источник:Цянь Точность время:2022-9-14

One of the biggest benefits of electric wheelchairs is the use of an electric drive that allows users to move freely even without having to push themselves manually or with human power. These wheelchairs are prepared for people in different situations, while allowing more people with inconvenient lives to regain their freedom.

The electric wheelchair includes a mobile seat part, a body part used as a seat support, a seat adjustment mechanism arranged under the seat to maintain the balance of the seat part, a underbody part located under the body part, and a crawler walking mechanism.

  Electric wheelchair characterized in that the safety locking device is a double-wing safety locking device comprising a housing, a pair of latching members fixed to the wall of the housing by the action of a power spring, two pinions, one of which is configured as a small motor, each latching member having a small tooth edge and a large tooth edge, each of the two pinions engaging the small tooth edge of one said latching member. The large tooth edges of the two latch members engage the teeth of the circular bottom edge of the longitudinal plate of the seat section when the safety locking device is in the locked state, and when in the unlocked state, the large tooth edges of the latch members leave the teeth of the circular bottom edge of the longitudinal plate driven by said pinion and are locked in their initial position by means of their respective power springs.

  The performance of key wheelchair components and accessories therefore determines the quality of life for people who sit in wheelchairs 12-18 hours a day. This power wheelchair is designed to provide a functional mobility tool suitable for a special population. Such a power wheelchair usually includes additional accessories that are essential for the successful use of the wheelchair. In particular, it is important to choose a good spring manufacturer to get the most out of the power spring, which is an important accessory for the safety lock.

  Qianye precision has also made product updates in technology for power springs. First of all, our company adopts 301 stainless steel material with high precision and high hardness. Its thickness tolerance is controlled within the range of 0.01mm, and its hardness is HV580 degrees, which greatly improves the quality stability of spring products and meets the different needs of different customers for products. At the same time, our spring forming technology is different from the traditional spring machine, and the independently developed stretch forming process (has obtained the invention patent).The manufacturing equipment is developed and manufactured by our company, and the spring produced greatly increases the service life of the spring.

  Shenzhen Qianye Precision Metal Co., Ltd. is a global spring manufacturer with more than 20 years of spring manufacturing experience. As a professional spring supplier, we can provide various power springs and various spring application designs and solutions. We sincerely suggest that customers can obtain consulting services from our R&D engineers at the initial stage of product introduction and development. According to customer needs and assist in product design, development, proofing, so that your product can find the best solution to meet your application needs.
