Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a fixing and locking component for automobiles. Background Technology

[0002] In the automotive manufacturing and assembly field, fastening and locking components (such as clips and clamps) are widely used for the installation and fixing of interior panels, wiring harnesses, pipes, and other components. For components that are long or require multiple points of support, such as roof trim strips, door sealing strips, and large wiring harnesses, multiple independent fastening components are usually installed side by side to achieve stable fixing.

[0003] However, existing locking components of this type have low installation accuracy and efficiency during application. Since these locking components are all independent units, they must be aligned and fixed to the vehicle body one by one during installation. This process is not only tedious and time-consuming, but also makes it difficult to ensure the relative positional accuracy between multiple locking components. Accumulated errors can easily lead to problems such as misalignment, uneven gaps, or stress concentration in the fixed parts, seriously affecting assembly quality and aesthetics. Furthermore, traditional locking components lack mechanical linkage, and each point can only provide isolated support. The vehicle inevitably generates continuous vibration during driving, causing slight relative movement between each locking component and the fixed part. After long-term use, they are prone to loosening due to wear, resulting in abnormal noise and deteriorating the vehicle's NVH (noise, vibration, and harshness) performance.

[0004] Therefore, a locking component for automobiles was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a fixing and locking component for automobiles. It solves the problems of existing automobile locking components requiring individual installation, which leads to difficulties in positioning and low efficiency when fixing at multiple points, and is prone to assembly problems due to accumulated errors. Furthermore, the lack of linkage between the locking components makes them prone to abnormal noises under vehicle vibration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A locking component for automobiles includes a fixing component, a fixing screw disposed on the fixing component, and a connector and a snap-fit ​​component respectively installed on both sides of the fixing component; the connector and the snap-fit ​​component can be snapped together to fix each other so as to splice multiple fixing components and realize the synchronous positioning and installation of multiple fixing components.

[0007] Preferably, the connector consists of two connecting plates connected by a damping hinge, and multiple toothed grooves are formed on the adjacent inner sidewalls of the two connecting plates.

[0008] Preferably, the multiple tooth grooves are combined to form a Christmas tree-shaped structure that is larger at the top and smaller at the bottom, and a rubber layer is fixedly provided on the inner wall of the tooth grooves.

[0009] Preferably, multiple sets of springs are fixedly disposed above the two connecting plates, and the multiple sets of springs are used to provide an elastic force to the two connecting plates to open them.

[0010] Preferably, the snap-fit ​​member is arc-shaped and is configured to compress the connecting plate of the adjacent fixing member when in contact with the connecting plate, overcome the elastic force of the spring to make it close, and after being snapped into the tooth groove, be tensioned by the restoring force of the spring.

[0011] Preferably, the outer wall of the snap-fit ​​component is covered with a rubber layer, and a limiting piece is fixedly provided on one side of it; the fixing component is made of rubber and can deform under force.

[0012] Preferably, a groove is provided on one side of the fixing member, and the connecting member is fixedly installed in the groove by screws, with a gap between the connecting member and the inner wall of the groove.

[0013] Preferably, the snap-fit ​​component is fixedly installed on the side of the fixing component away from the connector by screws; the snap-fit ​​component can slide upward along the groove of the adjacent fixing component and engage with the toothed groove of the connector in the groove.

[0014] Preferably, the toothed groove has a triangular structure and a lateral limiting surface at its bottom, so that the snap-fit ​​component inserted therein will not fall down.

[0015] Preferably, the limiting piece slides in the gap between the slide groove and the connector to achieve lateral limiting of the snap-fit ​​component and prevent it from falling off laterally.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves rapid splicing and overall installation of multiple fasteners through a snap-fit ​​design of connectors and snap-fit ​​parts, effectively solving the problems of positioning difficulties and low efficiency caused by the need for individual installation of traditional locking parts. The elastic snap-fit ​​mechanism, composed of a damping hinge, spring, and Christmas tree-shaped toothed groove, combined with the sliding engagement of the snap-fit ​​part with a limit plate and the slide groove, achieves locking during splicing and reliable anti-drop and anti-fall functions. Installation is effortless and provides a clear snap-fit ​​feel. The rubber layer on the toothed groove and the outer wall of the snap-fit ​​part effectively reduces vibration and noise, enhancing the adaptability of the locking part to irregular installation surfaces.

[0024] Please see Figure 1-4A type of automotive fixing and locking component includes a fixing component 1, a fixing screw 11 disposed on the fixing component 1, and a connector 2 and a snap-fit ​​component 3 respectively installed on both sides of the fixing component 1; the connector 2 and the snap-fit ​​component 3 can be snapped together to fix each other so as to splice multiple fixing components 1 and realize the synchronous positioning and installation of multiple fixing components 1. The connector 2 consists of two connecting plates 21 connected by a damping hinge 22. Multiple toothed grooves 211 are provided on the adjacent inner sidewalls of the two connecting plates 21. The multiple toothed grooves 211 are combined to form a Christmas tree-shaped structure that is larger at the top and smaller at the bottom. A rubber layer is fixedly provided on the inner wall of the toothed grooves 211. Multiple sets of springs 23 are fixedly provided above the two connecting plates 21. The multiple sets of springs 23 are used to provide elastic force to the two connecting plates 21 to open them. The snap-fit ​​3 is arc-shaped and is configured to press the connecting plate 21 of the adjacent fixing member 1 when it contacts the connecting plate (21), overcome the elastic force of the spring 23 to make it close, and after it is snapped into the tooth groove 211, it is tensioned by the restoring force of the spring 23. The outer wall of the snap-fit ​​3 is covered with a rubber layer, and a limit piece 31 is fixedly provided on one side of it. The fixing member 1 is made of rubber and can deform under force. A sliding groove 12 is provided on one side of the fixing member 1. The connecting member 2 is fixedly installed in the sliding groove 12 by screws, and there is a gap between it and the inner wall of the sliding groove 12. The snap-fit ​​component 3 is fixedly installed on the side of the fixing component 1 away from the connector 2 by screws; the snap-fit ​​component 3 can slide upward along the slide groove 12 of the adjacent fixing component 1 and engage with the toothed groove 211 of the connector 2 in the slide groove 12. The toothed groove 211 has a triangular structure and a lateral limiting surface at its bottom so that the snap-fit ​​component 3 inserted therein will not fall down. The limiting piece 31 slides in the gap between the slide groove 12 and the connector 2 to achieve lateral limiting of the snap-fit ​​component 3 and prevent it from falling off laterally.

[0025] In actual use, this automotive fixing locking component first uses fixing screws 11 to initially fix a single fixing component 1 to a preset position on the vehicle body. When multiple locking components need to be installed to fix long strips or large-area parts, the connecting component 2 and the snap-fit ​​component 3 can be used to snap the snap-fit ​​component 3 of the second locking component to be installed into the slide groove 12 of the already fixed locking component, and then push it upward along the groove. During this process, the rubber layer covering the outer side of the snap-fit ​​component 3 generates friction with the inner wall of the slide groove 12, providing initial movement damping. At the same time, the limiting piece 31 slides in the gap between the slide groove 12 and the connecting component 2. This design effectively prevents the snap-fit ​​component 3 from lateral displacement or falling off during the pushing process, achieving lateral limiting. When the top of the snap-fit ​​3 contacts and presses against the connecting plate 21 of the connector 2, the connecting plate 21 tends to open under the elastic force of the spring 23. However, its opening angle is constrained by the arc-shaped shape of the snap-fit ​​3, always maintaining a larger opening at the top and a smaller opening at the bottom. Under the pushing force, the snap-fit ​​3 rises as if climbing on the Christmas tree-shaped toothed groove 211, forcing the two connecting plates 21 to temporarily overcome the force of the spring 23 and close around the damping hinge 22. Once the snap-fit ​​3 slides past the target tooth tip, the connecting plate 21 quickly rebounds under the action of the spring 23, causing the snap-fit ​​3 to snap into the corresponding toothed groove 211. Because the toothed groove 211 is a triangular structure with a horizontal limiting surface at the bottom, the snap-fit ​​component 3 is reliably locked and will not fall. The rubber layer on the inner wall of the toothed groove 211 is closely fitted with the rubber layer on the outer wall of the snap-fit ​​component 3, which plays a role in vibration reduction and noise reduction. The two locking components are quickly positioned by the insertion and engagement of the connector 2 and the snap-fit ​​component 3. This process can be repeated to connect more locking components in series. All the assembled locking components form a whole, ensuring that multiple points along the linear path of the fixed object can be uniformly and firmly locked. This greatly simplifies the installation process of the multi-locking component system and effectively solves the problems of inaccurate positioning and low efficiency caused by the independent installation of each component in the traditional method. The fixing component 1 itself is made of rubber, which gives it a certain deformation capability and can better adapt to uneven installation surfaces, further improving the fixing effect.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
