Technical Field

[0001] The utility model relates to the field of automobile instrument crossbeam assemblies, and particularly relates to a lapping structure of an automobile instrument crossbeam assembly. Background Art

[0002] The automobile instrument panel crossbeam assembly is a key component in the automobile interior system. Specifically, it is installed at the front of the vehicle. The automobile instrument panel crossbeam assembly also mounts many components such as a steering column, an air conditioner, and a safety airbag. The space is relatively compact, and it also needs to conform to the routing of various wire harnesses.

[0003] In order to mount other automobile components on the automobile instrument panel crossbeam assembly, it is usually necessary to weld a corresponding lapping structure to play a role in supporting or bridging the automobile components. During the welding process, it is necessary to first lap or place the lapping structure on the automobile instrument panel crossbeam assembly and adjust the lapping structure to a precise position before welding operations can be carried out. However, since the part of the automobile instrument panel crossbeam assembly used to connect the lapping structure is usually cylindrical, the lapping structure is prone to shaking during the welding process, which in turn affects the subsequent welding accuracy. Therefore, it is necessary to make improvements to the lapping structure so that it can be firmly lapped on the automobile instrument panel crossbeam assembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lapping structure of an automobile instrument crossbeam assembly to solve the problem that since the part of the automobile instrument panel crossbeam assembly used to connect the lapping structure is usually cylindrical, the lapping structure is prone to shaking during the welding process. The specific technical solutions are as follows:

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase does not necessarily refer to the same embodiment at various places in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] Please refer to Figures 1-5 , in the embodiment of the present utility model, a lapping structure of an automotive instrument crossbeam assembly includes a lapping member 1. The lapping member 1 includes a lapping member body 11 and a bent end 12 connected to the lapping member body 11. The lapping member 1 lapps on the automotive instrument crossbeam assembly 2 through the bent end 12. A bendable fastening strip 3 is connected to the inner side of the bent end 12. A fastening ring 4 is connected to the side surface of the lapping member body 11. The fastening strip 3 is curved and the fastening strip 3 is inserted into the fastening ring 4. The lapping member body 11 is bound to the automotive instrument crossbeam assembly 2 through the fastening strip 3. Among them, the lapping member body 11 and the bent end 12 cooperate with the fastening strip 3 to enclose an accommodating space for installing the automotive instrument crossbeam assembly 2. By setting the fastening strip 3, the lapping member 1 can be locked on the automotive instrument crossbeam assembly 2, so that the lapping member 1 is not easily deviated from the predetermined position, ensuring the welding accuracy of the lapping member 1 and the automotive instrument crossbeam assembly 2.

[0024] In some embodiments, by optimizing the structures of the fastening ring 4 and the fastening strip 3, the fastening strip 3 can be adjusted unidirectionally after being inserted into the fastening ring 4. Specifically, the fastening ring 4 is provided with a channel 41 for inserting the fastening strip 3. The inner wall of the channel 41 is provided with a protruding limiting portion 42. A plurality of helical grooves 31 are arranged on the outer surface of the fastening strip 3 along its length direction. The limiting portion 42 is arranged in any one of the helical grooves 31. By designing the cooperation between the helical grooves 31 and the limiting portion 42, the fastening strip 3 can be prevented from retracting and loosening the restraint on the automotive instrument crossbeam assembly 2. If the perimeter of the automotive instrument crossbeam assembly 2 is shorter, the fastening strip 3 can be pulled forward to reduce the accommodating space, and then adapt to the automotive instrument crossbeam assembly 2; further, the limiting portion 42 includes inclined teeth, and the teeth cooperate with the helical grooves 31 to complete the clamping.

[0025] In some embodiments, a pull ring 31 is connected to the end of the fastening strip 3. By providing the pull ring 31, it is convenient to pull the fastening strip 3. The inner surface of the fastening strip 3 is covered with a rubber layer 32. By providing the rubber layer 32, it can be avoided that the fastening strip 3 and the vehicle instrument crossbeam assembly 2 are worn during the process of pulling the fastening strip 3. Secondly, the large friction force between the rubber layer 32 and the vehicle instrument crossbeam assembly 2 can also be used to prevent the overlapping member 1 or the vehicle instrument crossbeam assembly 2 from shifting.

[0026] In this embodiment, the material of the fastening strip 3 is plastic. After the overlapping member 1 or the vehicle instrument crossbeam assembly 2 is welded, the fastening strip 3 can be cut according to needs. Preferably, the surface of the fastening strip 3 is provided with a groove 33, and the groove 33 is arranged close to the bending end 12. By providing the groove 33, it is convenient to cut the fastening strip 3.

[0027] In addition, in some embodiments, improvements are also made to the overlapping member body 11. Specifically, the overlapping member body 11 is provided with a weight-reducing hole and a reinforcing rib. The reinforcing rib is arranged at the connection between the overlapping member body 11 and the bending end 12. By providing the reinforcing rib, the connection strength between the overlapping member body 11 and the bending end 12 can be strengthened, and by providing the weight-reducing hole, the weight of the overlapping member 1 can be appropriately reduced.

[0028] It should be noted that the terms "first", "second", etc. in this article are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include one or more of the described features.

[0029] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
