[0032] Reference Figures 1 to 7 and mainly refer to Figure 1 , 4 7. A positioning and mounting mechanism for a motor end cover according to a first aspect embodiment of the present invention includes a support base 100, a moving mechanism 200, and a mounting component 300. The support base 100 is provided with a first assembly portion 110 for placing a motor body. The first assembly portion 110 is provided with a first positioning structure, which is used to cooperate with the motor body to position the motor body. The moving mechanism 200 is disposed on the support base 100. The mounting component 300 is mounted on the moving mechanism 200. The mounting component 300 is provided with a second assembly portion 310. The assembly part 310 is used to place the motor end cover. The second assembly part 310 is arranged opposite to the first assembly part 110. The mounting part 300 can move relative to the support base 100 in the vertical direction through the moving mechanism 200. The second assembly part 310 is provided with a second positioning structure, which is used to cooperate with the motor end cover to position the motor end cover. When the motor body is placed in the first assembly part 110 and positioned, and the motor end cover is placed in the second assembly part 310 and positioned, the mounting part 300 can drive the motor end cover to move closer to the motor body.

[0033] By adopting the above structure, operators can quickly install the motor body onto the support base 100 and position the motor body. Simultaneously, they can quickly install the motor end cover onto the mounting component 300 and position the motor end cover. Then, the mounting component 300 is driven to move the motor end cover closer to the motor body, thus completing the overall positioning of the motor and moving the motor end cover to the installation position, facilitating subsequent installation and connection. Compared to traditional manual positioning methods, there is no need to observe whether the holes are aligned or to repeatedly adjust the position of the motor end cover relative to the motor body. The positioning operation is simple, quick, and more efficient.

[0034] To facilitate the installation of the motor end cover, and to prevent the motor end cover from shifting relative to the motor body due to external forces during installation, thus avoiding the need for repositioning, refer to... Figure 4 and Figure 5In some embodiments of this utility model, the second assembly part 310 is provided with a through third mounting hole 330. The third mounting hole 330 is used to align with the first mounting hole of the motor end cover and the second mounting hole of the motor body, so that the first connector can pass through the third mounting hole 330 and pass through the first mounting hole and the second mounting hole, so that the motor body and the motor end cover are fixedly connected by the first connector.

[0035] By adopting the above structure, operators can directly perform the installation process through the third mounting hole 330 after completing the overall positioning of the motor, making the installation more convenient and faster. At the same time, during the installation process, the first positioning structure maintains the positioning of the motor body, and the second positioning structure maintains the positioning of the motor end cover. At this time, the motor end cover cannot be offset relative to the motor body, thereby ensuring the normal progress of the installation process and avoiding the problem of needing to reposition due to offset.

[0036] It is understood that in this embodiment, the first connecting member is a screw, and the first mounting hole and the second mounting hole are threaded holes. Of course, depending on actual needs, the first connecting member can also be a bolt, a connecting pin, or other connecting member. This utility model does not specifically limit this.

[0037] Reference Figure 1 , 2 6. In some embodiments of this utility model, the first assembly part 110 is provided with an installation groove 130, the shape of the installation groove 130 corresponds to the shape of the motor body, and the installation groove 130 is used to place the motor body.

[0038] By adopting the above structure, when the motor body is placed in the mounting groove 130, the mounting groove 130 can restrict the movement of the motor body relative to the support base 100 in the horizontal direction, and at the same time can prevent the motor body from tipping over due to external forces. This allows the motor body to be placed and installed more reliably on the first assembly part 110, and the motor body is less likely to fall off the first assembly part 110 during positioning, thus requiring reinstallation.

[0039] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the first positioning structure includes a first positioning block 120 disposed on the side wall of the mounting groove 130, the first positioning block 120 being used to cooperate with the positioning groove of the motor body for positioning; or, the first positioning structure includes a first positioning groove disposed on the side wall of the mounting groove 130, the first positioning groove being used to cooperate with the positioning block of the motor body for positioning.

[0040] By adopting the above structure, the positioning block and the positioning groove cooperate to position the motor body in a simple and reliable manner, and the operator can quickly place the motor body in the first assembly part 110 and position it.

[0041] It should be noted that the first positioning structure can also be a first positioning pin located on the side wall or bottom wall of the mounting groove 130, and the first positioning pin can be positioned in conjunction with the positioning hole of the motor body.

[0042] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the second positioning structure includes a second positioning block 320 disposed on the bottom wall of the second assembly part 310, the second positioning block 320 being used for positioning in conjunction with the positioning groove of the motor end cover; or, the second positioning structure includes a second positioning groove disposed on the bottom wall of the second assembly part 310, the second positioning groove being used for positioning in conjunction with the positioning block of the motor end cover.

[0043] By adopting the above structure, the positioning block and the positioning groove are simple and reliable to match, and the operator can quickly place the motor end cover on the second assembly part 310 and position it.

[0044] It should be noted that the second positioning structure can also be a second positioning pin provided on the side wall or bottom wall of the second assembly part 310, and the second positioning pin can be positioned in conjunction with the positioning hole of the motor end cover.

[0045] Reference Figure 4 and Figure 5 In some embodiments of this utility model, the second assembly part 310 is provided with a magnetic element 340. When the motor end cover is installed on the second assembly part 310, the magnetic element 340 can attract the motor end cover.

[0046] By adopting the above structure, the motor end cover can be quickly installed and removed using the magnetic component 340. The installation and removal operation is simple and efficient. At the same time, the installation method using the magnetic component 340 can also eliminate the need to set up an installation structure on the second assembly part 310 or the motor end cover, thereby saving costs and making the surface of the motor end cover more aesthetically pleasing.

[0047] It should be noted that in this embodiment, the magnetic component 340 is a magnetic post embedded in the bottom of the second assembly part 310. To ensure uniform force distribution, magnetic posts are provided on both sides of the second assembly part 310 in this embodiment. The motor end cover is magnetic and can attract the magnetic posts. Of course, depending on actual needs, the magnetic component 340 can also be a circular or arc-shaped magnetic ring, or the second assembly part 310 itself can be magnetic; this utility model does not specifically limit this.

[0048] Reference Figure 1 , 46. In some embodiments of this utility model, the moving mechanism 200 includes a slide rail 210 and a slider 220. The slide rail 210 is connected to the support base 100, the slider 220 is slidably mounted on the slide rail 210, and the slider 220 is connected to the mounting component 300. The slider 220 can drive the mounting component 300 to move relative to the support base 100 in the up-down direction.

[0049] By adopting the above structure, the linear guide rail 210 enables the slider 220 to move precisely along the guide rail 210, resulting in higher positioning accuracy. The slider 220 has a low coefficient of friction, which allows the mounting component 300 to remain stable during sliding.

[0050] It should be noted that in some embodiments, the number of slide rails 210 is at least two, and the number of sliders 220 is the same as the number of slide rails 210. The sliders 220 are connected to the slide rails 210 one by one, so that the mounting member 300 is connected to multiple sliders 220, the force is more even, and the sliding of the sliders 220 is more stable.

[0051] To facilitate control of the vertical movement of the mounting component 300 relative to the support base 100, refer to... Figure 1 , 3 4. In some embodiments of this utility model, a push-pull mechanism 400 is also included. The push-pull mechanism 400 is connected to the mounting component 300. The push-pull mechanism 400 can drive the mounting component 300 to move closer to or away from the support base 100.

[0052] By adopting the above structure, operators can easily and effortlessly move the mounting component 300 using the push-pull mechanism 400, thereby improving the efficiency of positioning and installation.

[0053] Reference Figure 1 , 3 4. In some embodiments of this utility model, the push-pull mechanism 400 includes a connecting seat 410, a handle 420, a connecting rod 430, a push-pull rod 440, and a guide sleeve 450. The connecting seat 410 is connected to the moving mechanism 200 or the support seat 100. The connecting seat 410 is rotatably connected to the handle 420. The handle 420 is rotatably connected to the connecting rod 430. The connecting rod 430 is rotatably connected to the push-pull rod 440. The guide sleeve 450 is connected to the connecting seat 410. The push-pull rod 440 passes through the guide sleeve 450 and is connected to the mounting member 300. The handle 420 can swing in the up-down direction and drive the connecting rod 430 to swing, so that the connecting rod 430 drives the push-pull rod 440 to move relative to the guide sleeve 450 in the up-down direction.

[0054] Specifically, the connecting seat 410 has a first connecting hole 411, and the handle 420 has a second connecting hole 421. The first connecting hole 411 and the second connecting hole 421 correspond to each other. A connector passes through the first connecting hole 411 and the second connecting hole 421, so that the connecting seat 410 and the handle 420 are rotatably connected. The handle 420 has a third connecting hole 422, and the connecting rod 430 has a fourth connecting hole 431. The third connecting hole 422 and the fourth connecting hole 431 correspond to each other. A connector passes through the third connecting hole 422 and the fourth connecting hole 431, so that the handle 420 and the connecting rod 430 are rotatably connected. The connecting rod 430 has a fifth connecting hole 432, and the push-pull rod 440 has a sixth connecting hole 441. The fifth connecting hole 432 and the sixth connecting hole 441 correspond to each other. A connector passes through the fifth connecting hole 432 and the sixth connecting hole 441, so that the connecting rod 430 and the push-pull rod 440 are rotatably connected.

[0055] By adopting the above structure, when the operator lifts the handle 420 upwards, the handle 420 drives the connecting rod 430 to swing, causing the connecting rod 430 to drive the push-pull rod 440 to move upwards relative to the guide sleeve 450, and the push-pull rod 440 to move the mounting part 300 upwards; when the operator presses the handle 420 downwards, the push-pull rod 440 moves the mounting part 300 downwards. Thus, the push-pull mechanism 400 allows the movement of the mounting part 300 to be controlled by swinging the handle 420, making operation simple and convenient. At the same time, the handle 420 drives the connecting rod 430 to swing through the lever principle, making operation more effortless.

[0056] It should be noted that in this embodiment, the push-pull mechanism 400 is a rocker slider mechanism. When the handle 420 swings to the lowest point, the motor end cover is installed on the motor body, and the pressure angle of the push-pull mechanism 400 reaches 90°. At this time, the push-pull mechanism 400 self-locks. Thus, when the handle 420 swings to the lowest point, the push-pull mechanism 400 can also lock the mounting part 300, which makes it easy to install the motor end cover on the motor body.

[0057] Reference Figure 6 and Figure 7 In some embodiments of this utility model, the connecting seat 410 is provided with a fourth mounting hole 412, and the moving mechanism 200 or the support seat 100 is provided with a fifth mounting hole 230. One of the fourth mounting hole 412 and the fifth mounting hole 230 is an elongated hole, which is used to allow the second connecting member to move relative to the support seat 100 in the vertical direction within the elongated hole. The second connecting member can pass through the fourth mounting hole 412 and the fifth mounting hole 230, so that the connecting seat 410 and the moving mechanism 200 or the support seat 100 are fixedly connected by the second connecting member.

[0058] By adopting the above structure, the elongated hole allows the second connector to move within a certain range, which facilitates the adjustment of the relative position of the connector 410 and the moving mechanism 200 or the support 100 during assembly.

[0059] It should be noted that in some embodiments, when the motor is relatively high, the motor end cover may already be on the motor body before the handle 420 has swung to its lowest point, preventing the pressure angle of the push-pull mechanism 400 from reaching 90°. This makes it impossible to lock the mounting component 300 using the self-locking mechanism of the push-pull mechanism 400. Therefore, by adjusting the height of the connecting seat 410 relative to the support seat 100 through the elongated hole within the second connecting component, the handle 420 can be swung to its lowest point to achieve a 90° pressure angle for the push-pull mechanism 400 when positioning and installing motors of different heights.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
