[0001] This utility model relates to the technical field of motor housing rear end cover, specifically a motor housing rear end cover that is easy to assemble. Background Technology
[0002] The rear end cover typically supports the motor shaft with bearings to ensure stable operation of the shaft, allowing the motor rotor to rotate accurately within the stator bore, thereby achieving the conversion of electrical energy into mechanical energy.
[0003] A search revealed a Chinese patent with publication number CN220382846U that discloses a motor housing rear end cover that is easy to assemble. The rear end cover body is placed on a mounting plate, and then the rear end cover body is rotated. At this time, the rear end cover body drives the second arc-shaped fixing block into the first arc-shaped fixing groove, and the arc-shaped fixing rod enters the second arc-shaped fixing groove. Then the second arc-shaped fixing block presses against the third arc-shaped fixing block, and then the third arc-shaped fixing block drives the moving rod to move upward, and then it is fixed by the elastic force of the spring.
[0004] However, in existing technologies, during installation, workers generally need to manually align the outer shell body with the rear cover body using the positioning structure, which requires repeated adjustments and thus reduces work efficiency and labor intensity. In order to solve the problem of increased time caused by repeated adjustments in the positioning of existing technologies, this application proposes to provide a guiding component between the rear cover body and the outer shell body, thereby facilitating quick connection between the rear cover body and the outer shell body and improving installation efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

The rear end cover body is disposed at one end of the outer shell body. A support plate is disposed on the outer shell body, and a sliding plate is disposed on the rear end cover body. A fixing component is disposed between the support plate and the sliding plate. A limiting rod is disposed at one end of the outer shell body near the rear end cover body, and the limiting rod is inserted into the rear end cover body.
[0007] Furthermore, there are two support plates, which are symmetrically arranged on the outer shell body, and one end of each support plate is chamfered.
[0008] Furthermore, the fixing component includes a fixing block, which is slidably mounted on the support plate. The upper end of the fixing block is provided with a rotating shaft, and the support plate is provided with a fixing groove, into which the fixing block is inserted.
[0009] Furthermore, the rotating shaft is rotatably connected to the fixed block, and the two ends of the rotating shaft are provided with helical lines. The upper end of the support plate is provided with a helical groove, and the helical lines and the helical groove are threadedly connected.
[0010] Furthermore, a push plate is provided at the end of the support plate away from the slide plate, a spring is provided between the push plate and the support plate, a telescopic rod is provided inside the spring, one end of the telescopic rod is installed on the support plate, and the other end of the support plate is installed on the push plate.

[0012] Furthermore, a limiting plate is provided between the limiting rod and the outer shell body, the limiting plate is inserted into the rear end cover body, and the end of the limiting plate near the rear end cover body is set as an arc.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up components such as a support plate, a sliding plate, a limiting rod, and a fixing block, allows the sliding plate component to be placed on the support plate during installation. Then, the rear cover body is pushed to move the sliding plate on the support plate. The support plate guides the direction and position of movement, thereby achieving an accurate connection between the support plate and the rear cover body. This avoids repeated adjustments and alignments by the workers during installation, thus improving work efficiency.
[0015] 2. This utility model, through the arrangement of components including a rotating shaft, a spiral, a spiral groove, a spring, a telescopic rod, and a push plate, achieves a fixed position of the rotating shaft during operation by cooperating with the rotating shaft component, the spiral component, and the spiral groove, thereby indirectly restricting the position of the fixing block and maintaining the connection or separation between the fixing block and the fixing groove. When disassembling the rear end cover body, the spring component, the telescopic rod component, and the push plate component cooperate to automatically push the rear end cover body away from the outer shell body.

[0023] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.
[0024] Please see Figure 1 , Figure 4 The present invention provides an easy-to-assemble motor housing rear end cover, comprising an outer shell body 1 and a rear end cover body 2. The rear end cover body 2 is disposed at one end of the outer shell body 1. A support plate 3 is disposed on the outer shell body 1, and a sliding plate 4 is disposed on the rear end cover body 2. Two support plates 3 are provided, symmetrically disposed on the outer shell body 1. One end of the two support plates 3 is chamfered 15 to improve the support stability of the rear end cover body 2. A fixing component is provided between the support plate 3 and the sliding plate 4. A limiting rod 13 is provided at the end of the outer shell body 1 near the rear end cover body 2. The limiting rod 13 is inserted into the rear end cover body 2, and the limiting rod 13 and the rear end cover body 2 cooperate with each other to limit the relative position between the outer shell body 1 and the rear end cover body 2.
[0025] like Figure 2 , Figure 3As shown, the fixing component includes a fixing block 5, which is slidably mounted on the support plate 3. A rotating shaft 7 is provided at the upper end of the fixing block 5, and a fixing groove 6 is provided on the support plate 3. The fixing block 5 is inserted into the fixing groove 6. The operator moves the rotating shaft 7, which drives the fixing block 5 to move accordingly, thereby adjusting the height of the fixing block 5. When the fixing block 5 is inserted into the fixing groove 6, it restricts the position of the slide plate 4. When the fixing block 5 is separated from the fixing groove 6, it releases the restriction on the slide plate 4.
[0026] In this embodiment, the rotating shaft 7 is rotatably connected to the fixed block 5. The two ends of the rotating shaft 7 are provided with helical lines 8, and the upper end of the support plate 3 is provided with a helical groove 9. The helical lines 8 and the helical groove 9 are threaded together. Through the mutual cooperation between the helical lines 8 and the helical groove 9, the position of the rotating shaft 7 can be restricted, thereby preventing the rotating shaft 7 from moving during operation.
[0027] Combination Figure 4 , Figure 5 As shown, a push plate 12 is provided at the end of the support plate 3 away from the slide plate 4. A spring 10 is provided between the push plate 12 and the support plate 3. A telescopic rod 11 is provided inside the spring 10. One end of the telescopic rod 11 is installed on the support plate 3, and the other end of the support plate 3 is installed on the push plate 12. During installation, the slide plate 4 drives the push plate 12 to move, and the push plate 12 compresses and stores the spring 10. During disassembly, the spring 10 releases the force and pushes the push plate 12 to reset. The push plate 12 automatically pushes the slide plate 4 to move, realizing the automatic separation between the rear cover body 2 and the outer shell body 1.
[0028] In this embodiment, a cover plate 16 is provided on one side of the telescopic rod 11. The cover plate 16 is connected to the support plate 3 by fixing bolts. By opening the cover plate 16, the inner spring 10 and other components can be inspected and maintained.
[0029] In a preferred embodiment, a limiting plate 14 is provided between the limiting rod 13 and the outer shell body 1. The limiting plate 14 is inserted into the rear end cover body 2. The end of the limiting plate 14 near the rear end cover body 2 is set as an arc. The limiting plate 14 increases the contact area between the outer shell body 1 and the rear end cover body 2, thereby improving the stability of the connection.
[0030] The implementation principle is as follows: During installation, the slide plate 4 is first placed on the support plate 3. Then, the rear cover body 2 is pushed to drive the slide plate 4 to slide on the support plate 3, thereby guiding the position of the rear cover body 2 and achieving accurate connection between the limiting rod 13 and the rear cover body 2. While the slide plate 4 moves, it drives the push plate 12 to move. The push plate 12 compresses the spring 10. When the rear cover body 2 moves to the preset position, the operator drives the rotating shaft 7 to rotate. The spiral line 8 at the lower end of the rotating shaft 7 separates from the fixed block 5, and then the rotating shaft 7 pushes the fixed block 5 to move downward and connect with the fixed groove 6, thereby restricting the position of the slide plate 4. Then, the rotating shaft 7 is driven to rotate again. The spiral line 8 at the upper end of the rotating shaft 7 cooperates with the spiral groove 9, thereby restricting the position of the rotating shaft 7. When disassembly is required, the operation is reversed.
[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
