Description

Technical Field

[0001] This utility model relates to the field of wiper motor technology, specifically to a device for fixing the wiper motor connector. Background Technology

[0002] The wiper motor is an important component of a car's wiper system. It drives the wipers to reciprocate across the rear windshield to clear rainwater, snow, or dust from the glass, ensuring the driver has a clear view from the rearview mirror and rear window.

[0003] The wiper motor connector is connected to the vehicle's electrical system via a wiring harness. When the vehicle is driving on bumpy roads, the wiring harness shakes, which in turn causes the connector to shake. This can lead to problems such as abnormal noise or fatigue breakage of the wiper motor connector, affecting the normal operation of the wiper system. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a device for fixing the wiper motor connector, which solves the problem that the existing wiper motor connector is prone to shaking when the car is driving on bumpy roads.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for fixing a wiper motor connector is provided, including a fixing member and an automotive mounting plate both fixed to the wiper motor. The fixing member is provided with a connector fixing shell for fixing the wiper motor connector, and the connector fixing shell is detachably fixed to the automotive mounting plate.

[0007] The working principle of this solution is as follows: by fixing the wiper motor connector inside the connector housing on the fixing component, the shaking of the connector has been reduced to a certain extent. Considering that there is a certain distance between the connector and the wiper motor in the car wiper system, the connector housing on the fixing component is a cantilever beam structure. Therefore, the connector housing is detachably and fixedly connected to the car mounting plate. This not only facilitates installation, but also more effectively reduces the shaking of the connector when the car is driving on bumpy roads, ensuring the stability and reliability of the wiper system.

[0008] Furthermore, the fastener includes a cover plate bolted to the wiper motor. One end of the cover plate has a vertically mounted cantilever rib, and the other end of the cantilever rib extends to the outside of the wiper motor and is fixed to the connector housing. The wiper motor connector harness passes sequentially through the bottom of the cover plate and the cantilever rib, and is electrically connected to the connector inside the connector housing. The cover plate and cantilever rib not only fix the connector housing but also restrict the movement of the wiper motor connector harness.

[0009] Furthermore, the cantilever rib includes a horizontal section and an inclined section. The horizontal section covers the wiper motor and is fixed to a cover plate at one end. One end of the inclined section is fixed to the other end of the horizontal section, and the other end of the inclined section is angled downwards and fixed to the connector housing. The inclined section of the cantilever rib optimizes the structural layout, making the device more compact and reducing space occupation.

[0010] Furthermore, the car mounting plate is bolted to the wiper motor, and a support plate is provided on one side of the car mounting plate to snap onto the connector housing. By additionally providing a support plate on the car mounting plate to snap onto the connector housing, the installation process is simplified, and the fixing strength of the connector housing is further improved, preventing the connector from shaking.

[0011] Furthermore, the support plate has a buckle hole, and the outer wall of the connector fixing shell is provided with a buckle body. A through groove is provided through the buckle body, and a buckle claw is provided on the bottom of the outer side of the buckle body. The support plate is inserted into the through groove of the buckle body and is connected to the buckle claw through the buckle hole.

[0012] Furthermore, the support plate has a rectangular plate structure, and steps for limiting movement are provided on both sides of the support plate. The steps facilitate the limiting movement when the support plate is connected to the buckle body.

[0013] Furthermore, a first recessed groove is formed on the outer wall of the connector fixing shell near the through groove. Considering that a mold will be used to produce the connector fixing shell during the production process, and the connector fixing shell will be integrally formed with the through groove containing the buckle, the first recessed groove is provided to increase the thickness of the mold at the through groove, thereby increasing the strength of the mold and facilitating the integral forming production of the connector fixing shell.

[0014] Furthermore, a second recess is provided on the outer wall of the buckle body, with the first and second recesses located on opposite sides of the through groove. The second recess reduces the thickness of the buckle claw, facilitating a certain deformation of the buckle claw to engage with the buckle hole.

[0015] Furthermore, the buckle claw is provided with a protrusion that can be inserted into the buckle hole.

[0016] Furthermore, the buckle hole can be round or square.

[0017] This utility model discloses a device for fixing a wiper motor connector, the advantages of which are:

[0018] This utility model uses a fastener to fix the connector inside the connector fixing shell, which effectively reduces the shaking of the connector when the car is driving on bumpy roads. Furthermore, the connector fixing shell can be detachably fixed to the car mounting plate, which further improves the fixing strength of the connector fixing shell and more effectively reduces the shaking of the connector.

Detailed Implementation

[0024] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0025] The inventors considered that existing wiper motor connectors lack a fixing device, making them prone to wobbling when driving on bumpy roads, especially the rear wiper motor. Therefore, the inventors fixed the connector by incorporating a fixing member 100 on the wiper motor. Furthermore, to prevent wobbling caused by the cantilever beam structure of the fixing member 100, the fixing member 100 is further fixed to a vehicle mounting plate 200 for fixing the wiper motor, thereby greatly improving the fixing strength of the connector and effectively preventing wobbling. The device for fixing the wiper motor connector is shown in detail below.

[0026] This solution is a device for fixing the wiper motor connector, including a fastener 100 and an automotive mounting plate 200.

[0027] refer to Figure 1 and Figure 2 The fastener 100 is fixed to the wiper motor, and a connector fixing shell 13 for fixing the wiper motor connector is provided on it.

[0028] For details, please refer to Figure 3The fastener 100 includes a cover plate 11 bolted to the wiper motor. One end of the cover plate 11 has a vertically mounted cantilever rib 12, and the other end of the cantilever rib 12 extends to the outside of the wiper motor and is fixed to the connector housing 13. The wiper motor connector harness passes sequentially through the bottom of the cover plate 11 and the cantilever rib 12 and is electrically connected to the connector inside the connector housing 13. The cover plate 11 and the cantilever rib 12 not only fix the connector housing 13 but also restrict the movement of the wiper motor connector harness.

[0029] As a specific structure of the cantilever rib 12, the cantilever rib 12 includes a horizontal section 121 and an inclined section 122. The horizontal section 121 covers the wiper motor and one end is fixed to the cover plate 11; one end of the inclined section 122 is fixed to the other end of the horizontal section 121, and the other end of the inclined section 122 is inclined downward and fixed to the connector fixing housing 13. The setting of the inclined section 122 of the cantilever rib 12 optimizes the structural layout, making the device more compact and reducing space occupation.

[0030] refer to Figure 1 and Figure 2 The car mounting plate 200 is a sheet metal part for automobiles, made of metal. The car mounting plate 200 is bolted to the wiper motor. In this embodiment, a support plate 21 is provided on one side of the car mounting plate 200, which is snapped into the connector fixing housing 13. By additionally providing the support plate 21 on the car mounting plate 200, which is snapped into the connector fixing housing 13, the installation process is simplified, and the fixing strength of the connector fixing housing 13 is further improved, preventing the connector from shaking.

[0031] As a specific structure for the snap-fit ​​connection between the connector fixing housing 13 and the support plate 21, the support plate 21 has a snap-fit ​​hole 212, and a snap-fit ​​body 131 is provided on the outer wall of the connector fixing housing 13. A through groove is provided through the snap-fit ​​body 131, and a snap-fit ​​claw 132 is provided on the bottom of the outer side of the snap-fit ​​body 131. The snap-fit ​​claw 132 has a protrusion that fits into the snap-fit ​​hole 212. The support plate 21 is inserted into the through groove of the snap-fit ​​body 131 and snap-fitted with the snap-fit ​​claw 132 through the snap-fit ​​hole 212. In this embodiment, the snap-fit ​​hole 212 is either circular or square.

[0032] For easy positioning, the support plate 21 is a rectangular plate structure, and steps 211 for limiting the position are provided on both sides of the support plate 21.

[0033] As a further embodiment, refer to Figure 4 A first recessed groove 133 is provided on the outer wall of the connector fixing shell 13 near the through groove. A second recessed groove 134 is provided on the outer wall of the buckle body 131, and the first recessed groove 133 and the second recessed groove 134 are located on both sides of the through groove.

[0034] In this embodiment, the effect of the first sink 133 is as follows: considering that the connector fixing shell 13 will be produced by mold in the production process, and the connector fixing shell 13 will be integrally formed with a through groove with buckle 131, the thickness of the mold at the through groove is increased by setting the first sink 133, thereby increasing the strength of the mold and achieving the effect of facilitating the integral forming of the connector fixing shell 13.

[0035] The second recess 134 reduces the thickness of the latching claw 132, making it easier for the latching claw 132 to deform to engage with the latching hole 212.

[0036] In summary, the working principle of this solution to reduce connector wobbling is as follows:

[0037] By fixing the wiper motor connector inside the connector mounting housing 13 on the fixing member 100, the shaking of the connector has been reduced to a certain extent. Considering that there is a certain distance between the connector and the wiper motor in the car wiper system, the connector mounting housing 13 on the fixing member 100 is a cantilever beam structure. Therefore, the connector mounting housing 13 is detachably and fixedly connected to the car mounting plate 200, which further reduces the shaking of the connector when the car is driving on bumpy roads, thereby ensuring the stability and reliability of the wiper system.

[0038] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent.
