Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts manufacturing, and in particular to a hook-and-claw engagement structure between a grounding plate and a shock-absorbing pad. Background Technology

[0002] When the electric vehicle chassis is used to install and connect with the heat pump assembly (water-side integrated module), the design requires that the manifold mounting point on the water-side integrated module be used as the mounting point, with bushing shock absorption and then bolted to be fixed to the aluminum frame of the whole vehicle. One of the mounting points needs to be connected to the ground wire in the wiring harness assembly in the form of a grounding disc. The grounding disc needs to be approximately the same size as the bushing and aligned with the center to ensure that the fixing bolts can be installed normally.

[0003] Existing hook-and-pawl mating structures, such as the novel synchronizer gear ring and slider mating structure disclosed in utility model patent application number 202120242386.2, mainly include a gear ring and a slider. The slider is provided with a slider hook, and the gear ring is provided with a gear ring groove. The slider hook and the gear ring groove mate, and the slider hook drives the gear ring to move together, forming a gear ring and slider mating structure. In use, the gear ring and the slider are mated together. In neutral, the gear ring is always close to the slider side to ensure that there is a gap between the gear ring and the connecting tooth cone surface. This avoids drag torque between the friction surfaces when the gear ring and the connecting tooth rotate at different speeds during transmission operation, thus eliminating the energy consumption caused by the gear ring.

[0004] However, most existing methods connect the grounding plate and the shock-absorbing pad with glue. During the supply and transportation of the water-side integrated module or the handling of the whole vehicle, it is easy to fall off due to external forces such as vibration. Moreover, the manufacturing process requires the center of the grounding plate to be aligned with the bushing. Without an auxiliary alignment method, it is difficult to align them in one go. In addition, it is necessary to wait for the glue to dry completely, which makes the process uncertain and time-consuming. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hook-and-claw engagement structure between the grounding plate and the shock-absorbing pad, which reduces the possibility of the grounding plate falling off due to vibration or external force pulling caused by glue connection through physical connection. At the same time, it simplifies the manufacturing process by eliminating the need to control the amount of glue applied, thereby improving production efficiency and saving glue procurement costs.

[0006] This utility model discloses a hook-and-claw engagement structure between a grounding plate and a shock-absorbing pad, including a bushing mounted on a bolt; and a grounding contact plate mounted on the bolt and pressed tightly against the bushing; the grounding contact plate holds the bushing, and then the bolt passes through the bushing and the grounding contact plate to be fixedly connected to the aluminum frame of the vehicle. The bushing reduces vibration, and the grounding contact plate is connected to the ground wire in the wiring harness assembly.

[0007] Preferably, the bushing also has two slots and a recessed area at the mating point with the grounding plate. By creating two slots, it can be mated and connected to the grounding plate from both sides, saving the workers the trouble of adjusting and flipping it during installation. The recessed area at the mating point makes it easier to connect and improves stability.

[0008] Preferably, the grounding connector includes a connector body, a hook, and a wire clamp. The connector body is mounted on a bolt, the hook is mounted on the connector body, and the wire clamp is mounted on the connector body. The bushing is held in place by the hook, the ground wire in the wiring harness assembly is connected to the wire clamp, and the bolt passes through the connector body to fix it to the vehicle's aluminum frame.

[0009] Preferably, it also includes three sets of hooks with equal spacing between them; the three sets of hooks evenly distributed on the splice body can enhance the connection between the splice body and the bushing and prevent the bushing from falling off.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the grounding plate hugs the bushing, and then the bolt passes through the bushing and the grounding plate to fix and connect to the aluminum frame of the whole vehicle. By setting the bushing, vibration is reduced, and the grounding plate is connected to the ground wire in the wiring harness assembly. Attached Figure Description
