These problems reduce control efficiency and result in lower efficiency in achieving the desired execution effect, thus affecting the practicality of the telescopic cylinder. Optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a dexterous hand-load-bearing electric telescopic cylinder to solve the problems mentioned in the background art, such as insufficient load-bearing capacity and complex structure that limits dexterity of existing telescopic cylinders.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dexterous hand-load-bearing electric telescopic cylinder, comprising: a driver housing, a right end cover mounted on one side of the driver housing, and a left end cover mounted on one end of the driver housing, and further comprising a compact mounting assembly and a rotation adjustment assembly:

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a dexterous hand load-bearing electric telescopic cylinder, including: a driver housing 1, a right end cover 2 installed on one side of the driver housing 1, and a left end cover 3 installed on one end of the driver housing 1;

[0025] A compact mounting assembly is provided on the inner side of the drive housing 1. The compact mounting assembly includes a motor housing 4, a hollow cup motor 5 is connected to the inner side of the motor housing 4, and a nut pin 13 is connected to the top of the hollow cup motor 5. The compact mounting assembly is used for internal mounting of the telescopic cylinder.

[0026] The inner side of the drive housing 1 is provided with a rotation adjustment assembly, which includes a drive gear 7, a driven wheel 9 connected to one side of the drive gear 7, and a planetary roller screw 14 connected to one end of the driven wheel 9. The rotation adjustment assembly is used for the inner adjustment of the telescopic cylinder.

[0027] Specifically, such as Figure 3 As shown, the motor housing 4 is slidably connected to the bottom end of the driver housing 1. The motor housing 4 is fixedly connected to the right end cover 2 and the left end cover 3. The motor housing 4 is slidably snapped into the bottom inner side of the driver housing 1 and then connected through the right end cover 2 and the left end cover 3 on both sides for fixing the telescopic cylinder as a whole.

[0028] Specifically, such as Figure 2 As shown, the hollow cup motor 5 is fixedly installed on one end of the inner side of the driver housing 1, and the drive gear 7 is installed on one rotating end of the hollow cup motor 5. The hollow cup motor 5 drives the drive gear 7 to rotate.

[0029] Specifically, such as Figure 2 As shown, a snap ring 8 is fixedly installed on one side of the driving gear 7, and a snap ring 10 is fixedly installed on one side of the driven gear 9. The driving gear 7 meshes with the driven gear 9, and the rotation of the driving gear 7 drives the driven gear 9 to rotate. Snap ring 8 and snap ring 10 are used to improve the stability of the installation of the driving gear 7 and the driven gear 9.

[0030] Specifically, such as Figure 4 As shown, a lead screw nut 11 is connected to one end of the driven wheel 9. A retainer 12 is connected to both ends of the inner side of the lead screw nut 11. The retainer 12 is provided at both ends of the inner side of the lead screw nut 11 to facilitate the limiting of the end of the planetary roller lead screw 14.

[0031] Specifically, such as Figure 2 As shown, a planetary roller screw 14 is threadedly connected to the inner side of the screw nut 11, and a nut pin 13 is connected to one end of the outer side of the planetary roller screw 14. The rotation adjustment of the planetary roller screw 14 controls the position transmission of the nut pin 13.

[0032] Specifically, such as Figure 2 As shown, a displacement sensor 6 is provided on the outer side of the nut pin 13. The displacement sensor 6 is used to monitor the position of the nut pin 13 and facilitate distance control. A connecting rod fixing head 15 is threaded to one end of the outer side of the nut pin 13. The connecting rod fixing head 15 is connected to an external adjustment mechanism to facilitate position rotation.

[0033] Specifically, such as Figure 2 As shown, a frame fixing head 16 is threadedly connected to one side of the right end cover 2. The frame fixing head 16 is used to fix the electric telescopic cylinder.

[0034] In this embodiment, the driver housing 1 and motor housing 4 are set to be installed in parallel with the hollow cup motor 5 and nut pin 13 inside. This saves space and makes the installed structure more tightly connected. The rotation adjustment of the multi-structure is more precise. During the extension and retraction adjustment of the electric telescopic cylinder, the inner side is set to rotate in multiple positions. The driven wheel 9 is driven to rotate by the driving gear 7. Then, the driven wheel 9 drives the lead screw nut 11 and planetary roller lead screw 14 to adjust their positions, thereby driving the nut pin 13 to extend and retract, further improving the adjustment accuracy.

[0035] Specifically, before using the electric telescopic cylinder, the machine body needs to be fixed and installed using the frame fixing head 16. Then, the connecting rod fixing head 15 is connected to the corresponding mechanism. When the electric telescopic cylinder is in use, the hollow cup motor 5 drives the drive gear 7 to rotate, and then the drive gear 7 drives the driven wheel 9 to rotate, causing the planetary roller screw 14 connected to the inner side of the driven wheel 9 to rotate, causing the roller screw pair on the outer side of the planetary roller screw 14 to rotate. A guide block is provided on the outer side of the screw nut 11 to restrict the rotational motion of the screw nut 11 to change it into linear motion, driving the nut pin 13 and the connecting rod fixing head 15 to push outward, so that the multi-link mechanism fixed on the connecting rod fixing head 15 performs the corresponding movement.
