Description

Technical Field

[0001] This utility model relates to the technical field of wiper motor housing for thin-walled components, and in particular to a wiper motor housing for thin-walled components that is easy to assemble. Background Technology

[0002] As a specialized tool for cleaning car windshields, windshield wipers are driven by a dedicated wiper motor to make the wipers swing back and forth along the windshield for cleaning. As a type of windshield wiper motor, the thin-walled motor has a relatively thin motor housing compared to traditional motors. In order to improve the stability of the thin-walled wiper motor, a special thin-walled motor housing is often used.

[0003] Common thin-walled wiper motor housings, because they operate within the wiper blade, differ from traditional motors in that they not only have a traditional outer shell but also a metal housing at the front cover for mounting transmission components such as the turbine. While these common thin-walled wiper motor housings offer good stability during use, some issues still exist:

[0004] When assembling and installing common thin-walled wiper motor housings, they are mostly fastened with multiple sets of bolts, which is inefficient during production and processing. Utility Model Content

[0005] The purpose of this utility model is to provide an easy-to-assemble motor housing for thin-walled wiper components, thereby solving the problem of the cumbersome assembly of existing motor housings for thin-walled wiper components.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easy-to-assemble wiper thin-walled motor housing, including a motor housing body and a front cover plate. The front cover plate is installed on the top of the motor housing body. An auxiliary structure is fixedly connected to the top of the inner sidewall of the motor housing body. The auxiliary structure includes a sleeve, an insert, a slot, a positioning hole, a groove, and a buckle. The sleeve is fixedly connected to the bottom of the front cover plate. A bottom cover is fixedly connected to the bottom of the motor housing body. A conductive housing is fixedly connected to the top of the front cover plate. A heat dissipation structure is sleeved on the outer side of the motor housing body.

[0007] In use, when assembling the wiper thin-walled motor housing, the stator, windings and other parts are installed inside the motor housing body. Then, the motor housing body is connected to the front cover and closed. The wiper is then connected to the output end of the transmission housing, so that the motor with the wiper thin-walled motor housing can drive the wiper to reciprocate.

[0008] Preferably, the insert has an insert block inside, the top of the inner side wall of the motor housing body is fixedly connected to a slot, the insert block has a positioning hole inside, the upper side wall of the outer side wall of the motor housing body has a slot, and a buckle is installed inside the slot. The assembly of the motor housing is more convenient by snapping the buckle.

[0009] Preferably, the cross-sectional area of ​​the outer diameter of the insert is smaller than the cross-sectional area of ​​the inner diameter of the motor housing body, and the slot and the positioning hole are in a locking structure, so that the motor housing body is not easy to detach after docking with the front cover plate.

[0010] Preferably, several slots are fixedly connected to the top of the inner sidewall of the motor housing body, and the several slots are arranged in a ring at the top of the inner sidewall of the motor housing body. The friction between the motor housing body and the front cover plate is increased by the interlocking of several inserts with the slots.

[0011] Preferably, the heat dissipation structure includes a limiting groove, a retaining ring, a limiting block, folded heat dissipation fins, and a positioning protrusion. The limiting groove is formed on the outer side wall of the motor housing body. A retaining ring is fixedly connected to the top of the outer side wall of the bottom cover. A limiting block is fixedly connected to the top of the retaining ring. Folded heat dissipation fins are sleeved on the outer side of the motor housing body. A positioning protrusion is provided on the inner side wall of the folded heat dissipation fins. After the folded heat dissipation fins are installed, the inner wall is in close contact with the outer side wall of the motor housing body, thereby accelerating the heat conduction efficiency of the motor housing body.

[0012] Preferably, the limiting groove and the positioning protrusion are engaged, and the limiting block and the bottom end of the folding heat sink are embedded, so that the folding heat sink is not easy to move after installation.

[0013] Preferably, the limiting blocks are arranged in a ring at the top of the retaining ring to increase the friction between them and the folded heat dissipation fins.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the assembly of the motor housing of the thin-walled wiper component is more convenient through the double fixation of the insert and slot and the snap-fit; at the same time, foldable heat dissipation fins are fitted on the outside of the motor housing body to increase the heat dissipation area of ​​the motor housing of the thin-walled wiper component.

[0015] 1. When the front cover plate is pressed to align with the motor housing body, the insert will be inserted into the slot to form an embedded part. Then, the buckle is inserted into the slot and passes through the positioning hole to form a locking mechanism. The ring locking mechanism makes the connection between the motor housing body and the front cover plate more secure.

[0016] 2. When assembling the motor housing body, foldable heat dissipation fins are pre-fitted onto the outer side of the motor housing body, and the positioning protrusions on the inner wall of the foldable heat dissipation fins are engaged in the limiting groove, so that the inner wall of the limiting groove is stably and tightly attached to the outer wall of the motor housing body, thereby increasing the heat dissipation area of ​​the thin-walled motor housing.

Detailed Implementation

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

[0024] Please see Figures 1-5This utility model provides an easy-to-assemble wiper motor housing, comprising a motor housing body 1 and a front cover plate 2. The front cover plate 2 is installed on the top of the motor housing body 1, and a bottom cover 5 is fixedly connected to the bottom of the motor housing body 1. A conductive housing 3 is fixedly connected to the top of the front cover plate 2. An auxiliary structure 4 is fixedly connected to the top of the inner side wall of the motor housing body 1. The auxiliary structure 4 includes a sleeve 401, an insert 402, a slot 403, a positioning hole 404, a groove 405, and a buckle 406. The sleeve 401 is fixedly connected to the bottom of the front cover plate 2, and the sleeve 401 has an internal locking mechanism. There is an insert 402, and a slot 403 is fixedly connected to the top of the inner side wall of the motor housing body 1. The insert 402 has a positioning hole 404 inside, and a slot 405 is opened on the upper side of the outer side wall of the motor housing body 1. A buckle 406 is installed inside the slot 405. The cross-sectional area of ​​the outer diameter of the sleeve 401 is smaller than the cross-sectional area of ​​the inner diameter of the motor housing body 1. The slot 405 and the positioning hole 404 are in a snap-fit ​​structure. Several slots 403 are fixedly connected to the top of the inner side wall of the motor housing body 1, and the several slots 403 are arranged in a ring at the top of the inner side wall of the motor housing body 1.

[0025] See attached document Figure 1 , Figure 2 and Figure 3 When assembling and using the motor housing of this thin-walled wiper component, the stator, rotor, and other parts of the thin-walled motor are installed inside the motor housing body 1, and the motor housing body 1 is assembled with the front cover plate 2. Traditional assembly methods mostly use bolts or rivets, which are time-consuming in mass production. To address this, several slots 403 are fixed at the top of the inner wall of the motor housing body 1. When the front cover plate 2 is pressed to align with the motor housing body 1, the insert 402 is inserted into the slot 403 to form an embedded shape, thereby increasing the closing friction between the motor housing body 1 and the front cover plate 2, making it less likely for the motor housing body 1 to detach from the front cover plate 2. Subsequently, the buckle 406 is inserted into the slot 405 and passes through the positioning hole 404 to engage with the slot 403. The ring engagement method makes the connection between the motor housing body 1 and the front cover plate 2 more stable, and no bolts or other fasteners or matching tools are needed during assembly, making the assembly of the motor housing of this thin-walled wiper component more convenient.

[0026] A heat dissipation structure 6 is fitted on the outer side of the motor housing body 1. The heat dissipation structure 6 includes a limiting groove 601, a retaining ring 602, a limiting block 603, folded heat dissipation fins 604, and a positioning protrusion 605. The limiting groove 601 is opened on the outer side wall of the motor housing body 1. The retaining ring 602 is fixedly connected to the top of the outer side wall of the bottom cover 5. The limiting block 603 is fixedly connected to the top of the retaining ring 602. The folded heat dissipation fins 604 are fitted on the outer side of the motor housing body 1. The positioning protrusion 605 is provided on the inner side wall of the folded heat dissipation fins 604. The limiting groove 601 and the positioning protrusion 605 are in a snap-fit ​​structure. The limiting block 603 and the bottom end of the folded heat dissipation fins 604 are in an embedded structure. The limiting blocks 603 are distributed in a ring at the top of the retaining ring 602.

[0027] See attached document Figure 1 , Figure 2 , Figure 4 and Figure 5 In common thin-walled motors, heat dissipation is achieved by applying a heat sink layer to the outer wall of the motor housing body 1 during use, or by creating fins on the outer wall during the production of the motor housing. This significantly increases the production cost and processing complexity of the thin-walled motor housing. Therefore, during the assembly of the motor housing body 1, folded heat sink fins 604 are pre-fitted onto the outer side of the motor housing body 1, and the positioning protrusions 605 on the inner wall of the folded heat sink fins 604 are engaged in the limiting grooves 601. At the same time, the retaining ring 602 abuts against the bottom of the folded heat sink fins 604, and the limiting block 603 is embedded in the bottom groove of the folded heat sink fins 604. This ensures that the inner wall of the limiting groove 601 is stably and tightly attached to the outer wall of the motor housing body 1, allowing the heat absorbed by the motor housing body 1 to be quickly conducted to the folded heat sink fins 604. This increases the heat dissipation area of ​​the thin-walled motor housing and reduces its cost and production complexity.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
