Problems solved by technology
[0004] However, the existing electric cylinder still has the following problems in actual use. Due to its complex structure and various components, it is not only difficult to assemble and assemble, but also the cost of materials and processing of the components is relatively high, so it is greatly improved. reduces its usability
In addition, the positions of the torque transmission components of the cylinder coupling parts are not checked correspondingly when they are clutched, so when the next fitting is performed, the alignment of the torque transmission components often occurs inaccurately. Makes it impossible for each torque transmission component to be embedded for transmission, and causes extreme inconvenience in use and operation

Embodiment Construction
[0076]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0077] Please refer to Figure 1 to Figure 5 As shown, the present invention provides an electric cylinder with a position detection mechanism, which mainly includes a main body 10 , a transmission mechanism 20 , a quick release mechanism 30 and a position detection mechanism 40 .
[0078] The main body 10 includes a base 11 and a motor 15. The base 11 has a lower shell seat 12 and an upper shell seat 13 that is covered and assembled correspondingly to the lower shell seat 12. Each shell seat 12, 13 is roughly half-cylindrical. , a hollow cavity 14 is formed between the upper housing base 13 and the lower housing base 12, and the upper housing base 13 and the lower housing base 12 ...

The invention provides an electric cylinder with a position detection mechanism. The electric cylinder comprises a body, a transmission mechanism, a rapid releasing mechanism and the position detection mechanism, wherein the transmission mechanism comprises a worm gear member and a driving screw, and the worm gear member is provided with a plurality of convex keys. The driving screw is sleeved with the rapid releasing mechanism which comprises a clutch wheel, the clutch wheel and the worm gear member can perform mutual axial displacement, and the clutch wheel is provided with a plurality of key grooves allowing the convex keys to be in engaged transmission or releasing transmission. The position detection mechanism comprises a variable resistor, a driving wheel and a driven wheel, wherein the driving screw is sleeved with the driving wheel which rotates along with the driving screw, and the driving wheel is connected with the variable resistor and is in engaged transmission with the driving wheel. When the worm gear member is released from the clutch wheel, the variable resistor generates a specific resistance value. Therefore, the position where the worm gear member is released from or is in engaged connection with the clutch wheel can be controlled accurately.
Description
technical field [0001] The invention relates to an electric cylinder, especially an electric cylinder with a position detection mechanism. Background technique [0002] It is quite common and common to apply electric cylinders (Actuator) to electric hospital beds, treadmills, wheelchairs and other equipment to adjust the height of the position or the size of the elevation angle; among them, it has fast The electric cylinder of the release mechanism can quickly adjust and change the hospital bed to gain the most precious golden rescue time. [0003] The existing electric cylinder mainly includes a main body, a transmission mechanism and a quick-release mechanism. The main body includes an electric motor and a worm protruding outward from the center of the motor, and the transmission mechanism includes a lead screw and is sleeved on the lead screw. One end and a worm wheel engaged with the aforementioned worm, the quick release mechanism includes two cylindrical coupling part...
