[0038] Reference Figures 1 to 5 The present invention provides a control handle 100 .

[0039] In an embodiment of the present invention, the control handle 100 is applied to a driving mechanism, which (not shown) also includes a motor (not shown). The control handle 100 is connected to the motor through a line or a wireless module to control the start and stop, speed or output power of the motor.

[0040] Specifically, the shell 10 of the control handle 100 includes a shell 11, an end cover 12 and a connecting pipe 13, wherein the shell 11 and the end cover 12 are a shell 11 structure integrally formed of a plastic material, the shell 11 is formed with an installation cavity 11a and a avoidance hole 11b connected to the installation cavity 11a, the end cover 12 is threadedly connected to one end of the shell 11, and is provided with a avoidance hole connected to the installation cavity 11a, the connecting pipe 13 extends into the installation cavity 11a through the avoidance hole, and the connecting pipe 13 is used to prevent the circuit connecting the control board 21 and the motor from being exposed, so as to improve the safety and service life of the driving mechanism.

[0041] The control panel 21 of the control assembly is arranged in the installation cavity 11a, the sealing portion 222 of the button 22 is arranged in the installation cavity 11a and connected to the control panel 21, the operating portion 221 is connected to the sealing portion 222, and a portion is exposed by the avoidance hole 11b, the tenon seat 30 is inserted into the installation cavity 11a, and abuts against the plate surface of the control panel 21 on the side away from the sealing portion 222, so that the sealing portion 222 abuts against the cavity side wall of the installation cavity 11a, the sealing member 42 of the sealing assembly 40 is connected to the opposite end of the shell 11 away from the end cover 12, and is detachably inserted into the open end of the installation cavity 11a to seal the installation cavity 11a, and the bottom shell 41 is detachably connected to the sealing member 42.

[0042] When the control handle 100 of the present invention is assembled, the sealing part 222 is pre-connected to the control board 21, and the control board 21 is accommodated in the installation cavity 11a. At this time, the sealing part 222 corresponds to the avoidance hole 11b, and the tenon seat 30 is inserted into the installation cavity 11a, and the control board 21 is lifted toward the side of the avoidance hole 11b, so that the sealing part 222 abuts against the cavity side wall of the installation cavity 11a, and the operating part 221 is exposed from the avoidance opening, and the sealing part 222 abuts against the cavity side wall of the installation cavity 11a, separating the avoidance hole 11b from the installation cavity 11a. The sealing member 42 is detachably connected to the tenon seat 30, and covers the open end of the installation cavity 11a to seal the open end of the installation cavity 11a. In the present application, the sealing portion 222 and the sealing member 42 are both connected to the tenon seat 30, and the installation cavity 11a is formed into a closed space by the sealing portion 222 and the sealing member 42. In this way, the structure of the control handle 100 is relatively simple, and its disassembly and maintenance are relatively convenient. In addition, the sealing member 42 and the sealing portion 222 are assembled by the tenon seat 30, which largely avoids the occurrence of inadequate sealing, thereby improving the sealing performance of the control handle 100.

[0043] Please see again Figure 2In one embodiment of the present invention, the tenon seat 30 is provided with a guide surface 31 and a top surface 32, wherein the tenon seat 30 can be formed of metal or plastic material, and the top surface 32 and the guide surface 31 are formed at the upper end of the tenon seat 30, that is, the side facing the avoidance hole 11b during assembly, wherein the top surface 32 is extended along the length direction of the housing 11, and the extension track is adapted to the extension track of the control board 21, so that when the top surface 32 abuts against the board surface of the control board 21, its contact area is maximized, and the two are assembled more tightly, thereby improving the sealing effect of the sealing part 222. The guide surface 31 is provided on the side of the tenon seat 30 facing the end cover 12, and the top surface 32 extends horizontally in the present application, and the angle between the guide surface 31 and the top surface 32 is an obtuse angle. During assembly, the tenon seat 30 is inserted into the installation cavity 11a from the opening of the housing 11 away from the end cover 12.

[0044] In the present application, the control panel 21 and the button 22 are pre-assembled outside the shell 11, and are placed in the installation cavity 11a as a whole after the assembly is complete. The operating part 221 corresponds to the avoidance hole 11b, and the tenon seat 30 extends from the opening end of the installation cavity 11a. The guide surface 31 is pre-pressed against the control panel 21. As the tenon seat 30 continues to penetrate deeper, the guide surface 31 gradually lifts the control panel 21 toward the side of the avoidance hole 11b, so that the top surface 32 presses against the lower plate surface of the control panel 21, and then the sealing part 222 presses against the cavity side wall of the installation cavity 11a, and the operating part 221 is exposed from the avoidance hole 11b. In the present application, through the guiding effect of the guide surface 31, on the one hand, it is more labor-saving when assembling the tenon seat 30, and on the other hand, it can prevent the tenon seat 30 from damaging the control panel 21 when it is inserted into the installation cavity 11a, thereby improving the production yield of the control handle 100.

[0045] Furthermore, a guide groove 30a is provided on the side of the tenon seat 30 away from the guide surface 31. The guide groove 30a is opened on the side of the tenon seat 30 away from the top surface 32 and extends along the length direction of the tenon seat 30. The side wall of the installation cavity 11a is convexly provided to form a guide rib 111. The guide rib 111 is an integrally formed structure with the shell 11 and extends along the length direction of the shell 11. The cross-section thereof is formed to be adapted to the cross-section of the guide groove 30a. When the tenon seat 30 is inserted into the shell 11, the guide rib 111 is slidably embedded in the guide groove 30a. In the present application, the guide groove 30a and the guide rib 111 are used to prevent the tenon seat 30 from being misaligned and stuck when it is inserted into the installation cavity 11a, thereby ensuring the assembly efficiency and improving the assembly yield.

[0046] In one embodiment of the present invention, the operating portion 221 and the sealing portion 222 are integrally formed of elastic materials such as silicone or rubber, wherein the operating portion 221 has a waist-shaped profile, and the sealing portion 222 includes a sealing plate 2221 and a sealing convex rib 2222. The sealing plate 2221 is rectangular and connects the operating portion 221 and the control board 21, and the sealing convex rib 2222 is disposed around the outer side of the operating portion 221. When the tenon seat 30 is inserted into the installation cavity 11a, the guide plate lifts the control board 21 so that the abutting surface 32 abuts against the lower plate surface of the control board 21, and the operating portion 221 extends out of the avoidance hole 11b. The sealing convex rib 2222 elastically abuts against the sealing plate 2221 and the control board 21, separating the avoidance hole 11b from the installation cavity 11a, thereby preventing impurities or liquids from entering the installation cavity 11a through the gap between the operating portion 221 and the avoidance hole 11b, so that the sealing performance of the control handle 100 is better.

[0047] Please see again Figure 3 and Figure 5 In order to further simplify the overall structure of the control handle 100 and make the disassembly, assembly and maintenance of the control handle 100 more convenient, in one embodiment of the present invention, the control board 21 is provided with a connection hole 21a that runs through the upper and lower board surfaces thereof, and the board surface of the sealing plate 2221 that is away from the sealing rib 2222 is provided with a connection protrusion 2223, and the connection protrusion 2223 is engaged in the connection hole 21a to connect the sealing plate 2221 and the control board 21. In the present application, the number of the connection holes 21a is two, and the two connection holes 21a are arranged in the control board 21 at intervals, and the two connection protrusions 2223 are respectively engaged in the two connection holes 21a, which can not only connect the sealing plate 2221 and the control board 21, but also position the button 22 and the control board 21, thereby improving the assembly accuracy. Of course, the connection hole 21a can also be set as a rectangular connection hole 21a, so that while ensuring the assembly accuracy, the processing of the button 22 and the control board 21 is more convenient. The shapes and numbers of the connection holes 21a and the connection protrusions 2223 are not particularly limited.

[0048] In one embodiment of the present invention, the control assembly further includes a support seat 23, which is used to pre-position the control assembly in the installation cavity 11a, wherein the support seat 23 is convexly provided with two positioning bosses 231, and the control panel 21 is provided with a positioning hole 21b that passes through its two opposite board surfaces, and the diameter of the positioning hole 21b is slightly larger than the diameter of the positioning boss. During actual assembly, the button 22 is connected to the control panel 21, and the control panel 21 is pre-positioned on the support seat 23 through the positioning boss 231 and the positioning hole 21b, and then the three are placed in the installation cavity 11a. It should be noted that when the control panel 21 is placed on the support seat 23, the edges on both sides thereof should protrude from the support seat 23, so that when the tenon seat 30 is inserted into the installation cavity 11a, the abutting surface 32 abuts against its protruding part.

[0049] Please see again Figure 3 In the present application, the tenon seat 30 is provided with a slot 30b, and the support seat 23 is provided with a spring buckle 232. When the tenon seat 30 is inserted into the installation cavity 11a, the spring buckle 232 is elastically embedded in the slot 30b. Through the force of the spring buckle 232 against the bottom wall of the slot 30b, the tenon seat 30 and the support seat 23 are respectively pressed against the side walls of the installation cavity 11a. In this way, the internal structure of the control handle 100 is more tightly connected, thereby avoiding the control handle 100 from making abnormal noises during use.

[0050] In one embodiment of the present invention, the seal 42 includes a main body 421 and a buckle 424, wherein the main body 421 and the buckle 424 are integrally formed of an elastic material, and the elastic material may be silicone, rubber or thermoplastic polyurethane elastomer rubber (TPU Thermoplastic polyurethanes). The outer contour size of the main body 421 is slightly larger than the opening size of the mounting cavity 11a. When the tenon seat 30 is inserted into the mounting cavity 11a, the main body 421 is elastically sleeved on the open end of the mounting cavity 11a, and its outer side surface abuts against the cavity side wall of the mounting cavity 11a to seal the open end of the mounting cavity 11a. The buckle 424 elastically snaps into the card hole to connect the main body 421 with the tenon seat 30. In this way, the connection structure between the seal 42 and the shell 11 is simple, which facilitates the disassembly and assembly of the control handle 100.

[0051] Furthermore, the sealing member 42 further includes a limiting protrusion 422 connected to the body 421, and the tenon seat 30 is provided with a limiting hole 30c penetrating two opposite surfaces thereof, and the limiting protrusion 422 is inserted into the limiting hole 30c. The present application limits the limiting protrusion 422 in the limiting hole 30c, so that the sealing member 42 can be prevented from being lost when the control handle 100 is disassembled.

[0052] In one embodiment of the present invention, the control board 21 includes a board body 211 and a connection interface 213 and a switch 212 connected to the board body 211, wherein the board body 211 is a printed circuit board (PCB Printed Circuit Board), the type of the connection interface 213 can be one or more of USB, micro USB, Type-C, and Lightning, and the type of the connection interface 213 is not specifically limited, the connection interface 213 and the switch 212 are connected to the board body 211 by welding, the connection interface 213 is used to charge the control handle 100 or input a corresponding program, and the switch 212 is used to control the switch 212 of the control handle 100, and the body 421 is provided with a sealing protrusion 423, the body 421 is connected to the opening end of the installation cavity 11a, and the sealing protrusion 423 is plugged into the connection interface 213. In this way, impurities and liquids can be prevented from entering the connection interface 213, and the performance of the control handle 100 is guaranteed.

[0053] The present invention also proposes a driving mechanism, which includes a motor and a control handle 100. The specific structure of the control handle 100 refers to the above embodiment. Since the present driving mechanism adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. It can be understood that the motor can be a servo motor or a stepper motor, and the control handle 100 can also control other electrical equipment. For example, in one embodiment, the control handle 100 communicates with the intelligent robot through a WIFI module, and the start and stop, preset actions, etc. of the intelligent robot can be controlled by the control handle 100. The specific application of the control handle 100 is not specifically limited here.

[0054] The present invention further provides a method for assembling a control handle 100. In one embodiment, the method for assembling the control handle 100 includes the following steps:

[0055] S10: Assemble the sealing portion 222 of the button 22 on one side of the control board 21, and then place the control assembly assembled with the control board 21 and the button 22 into the installation cavity 11a from the opening end of the installation cavity 11a, so that the operating portion 221 of the button 22 faces the avoidance hole 11b;

[0056] S20: Insert the tenon seat 30 into the installation cavity 11a from the open end of the installation cavity 11a, so that the tenon seat 30 abuts against the lower surface of the control board 21, the sealing portion 222 abuts against the side wall of the installation cavity 11a, and the operating portion 221 extends out of the avoidance hole 11b;

[0057] S30: Assemble the sealing member 42 with the tenon seat 30 and insert it into the open end of the installation cavity 11a, and then assemble the bottom shell 41 on the sealing member 42 to seal the installation cavity 11a.

[0058] In the present application, the sealing portion 222 and the sealing member 42 are both connected to the tenon seat 30, and the installation cavity 11a is formed into a closed space by the sealing portion 222 and the sealing member 42. In this way, the structure of the control handle 100 is relatively simple, and its disassembly and maintenance are relatively convenient. In addition, the sealing member 42 and the sealing portion 222 are assembled by the tenon seat 30, which largely avoids the occurrence of inadequate sealing, thereby improving the sealing performance of the control handle 100.
