[0025] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, "second" information can also be referred to as "first" information.

[0026] As Figure 1 shown, the automobile trademark of the preferred embodiment of the present application comprises a base 1, a decorative cover 2 and a double-sided adhesive layer 3. For the convenience of description, reference is made to Figure 1 , Figure 3 , Figure 4 , the length direction of the base 1 is defined as the first direction X, the width direction of the base 1 is defined as the second direction Y, and the height direction of the base 1 is defined as the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Among them, the base 1 serves as a mounting carrier, one end of which is connected with the decorative cover 2 in the third direction Z, and the other end is provided with the double-sided adhesive layer 3 for bonding and fixing with the automobile counterpart, specifically, in order to limit the installation of the decorative cover 2, as Figure 1 , Figure 2As shown, the base 1 is provided with a limiting groove 11 at one end in the third direction Z, and the decorative cover 2 is installed in the limiting groove 11. In order to increase the connection strength between the decorative cover 2 and the base 1, a plurality of hot melt columns 21 are arranged at one end of the decorative cover 2 facing the base 1. Corresponding through holes 12 are arranged in the limiting groove 11 corresponding to the hot melt columns 21. The base 1 and the decorative cover 2 are welded and fixed by the hot melt columns 21 passing through the through holes 12. That is, by the hot riveting process, the end of the hot melt column 21 passing through the through hole 12 is heated, melted and cooled to be welded and fixed with the base 1. The base 1 and the decorative cover 2 are bonded without using double-sided tape, the overall connection strength between the base 1 and the decorative cover 2 is improved, and the assembly efficiency is improved.

[0027] Further, in the prior art, most domestic black car trademarks, the decorative cover 2 is generally made of high-brightness black spraying injection molding process or made of injection molding and then sprayed to form a finished product. The above two manufacturing processes have poor processing effect on complex surface features of the decorative cover 2 and poor overall appearance quality. Therefore, in the embodiment, the decorative cover 2 is made of an ABS film forming process (usually made of ABS plastic, processed by suction forming process. This process includes absorbing the preheated softened ABS plastic sheet on the surface of the mold, forming concave-convex texture by negative pressure, and then cooling and solidifying to form the product) and INS injection molding process (putting the ABS film sheet pre-formed by suction forming and completed by punching into the injection mold, and then injecting after closing the mold). That is, the ABS film sheet is punched and formed, and then INS injection is made to form the decorative cover 2. That is, one end of the decorative cover 2 with the convex block 22 is formed by the ABS film forming and then punched to a predetermined size, and then the INS injection is made to form the decorative cover 2, so as to improve the overall appearance quality and complex surface feature processing effect of the decorative cover 2. In order to reduce the injection cost and reduce the material amount of the hot melt column 21 structure, as shown in the figure, Figure 4 As shown, the end of the hot melt column 21 away from the decorative cover 2 is provided with a blind hole 211, which can reduce the structure amount of the hot melt column 21. Further, in order to ensure the connection strength between the decorative cover 2 and the base 1, as shown in the figure, Figure 4 As shown, the outer diameter of the hot melt column 21 is D, the inner diameter of the blind hole 211 is d, and 1mm≤D-d≤1.6mm, that is, the wall thickness of the hot melt column 21 is between 0.5mm-0.8mm, which meets the corresponding processing requirements. Preferably, in the embodiment, the outer diameter of the hot melt column 21 is 4mm, and the inner diameter of the blind hole 211 is 3mm.

[0028] Further, in order to avoid the overflow of the material after the melting of the hot-melt column 21, which leads to the uneven end surface of the double-sided adhesive layer 3 and the base 1, affecting the bonding strength with the counterpart of the automobile, in the embodiment, a counterbore 14 coaxial with the through hole 12 is arranged at the end of the base 1 away from the decorative cover 2, avoiding the overflow of the material after the melting of the hot-melt column 21, and at the same time, increasing the contact area between the material after the melting of the hot-melt column 21 and the base 1, further improving the connection strength between the base 1 and the decorative cover 2. Further, in order to make the connection between the base 1 and the decorative cover 2 uniform, the number of the hot-melt columns 21 is at least 3, and is uniformly distributed at the end of the decorative cover 2 facing the base 1, which can be adjusted according to the shape of the decorative cover 2 and the base 1. In the embodiment, the number of the hot-melt columns 21 is 4.

[0029] Further, in order to facilitate the design of the complex surface features on the decorative cover 2, making the overall appearance of the decorative cover 2 more uniform, in the embodiment, as shown in Figure 5 、 Figure 6 、 Figure 7 the end surface of the decorative cover 2 away from the base 1 is uniformly distributed with the protrusions 22 along the first direction X and the second direction Y, and the shape of the protrusions 22 is a regular quadrangular pyramid. The surface structure of the regular quadrangular pyramid is the same, which can make the overall appearance of the decorative cover 2 more uniform.

[0030] In some embodiments, in order to facilitate the processing of the protrusions 22, the bottom edge length of the protrusions 22 is L, and 0.8mm≤L≤2mm. In the embodiment, preferably, the bottom edge length of the protrusions 22 is 0.83mm. If L is less than 0.8mm, the processing difficulty is relatively large. For example, in the injection molding process, the excessively small protrusions 22 are difficult to accurately form, which is easy to cause size deviation or deformation. If L is greater than 2mm, the size of the protrusions 22 is too large, and the excessively large protrusions 22 will make the surface of the decorative cover 2 too conspicuous, affecting the overall appearance. At the same time, the excessively large protrusions 22 will also increase the material consumption and production cost.

[0031] Further, in some embodiments, the distribution density of the protrusions 22 also needs to be carefully considered. Too dense protrusions 22 can make the surface of the decorative cover 2 too crowded, affecting the overall appearance; and too sparse protrusions 22 can not form enough stereoscopic and hierarchical effects, therefore, the height of the protrusions 22 is H, and the spacing between the adjacent two protrusions 22 is M, H=M. Preferably, in the embodiment, the height of the protrusions 22 is 0.2mm, and the spacing between the adjacent two protrusions 22 is 0.2mm. According to the actual production requirements, the size of H and M can be adjusted correspondingly.

[0032] Further, the base 1 is generally made of ABS material by injection molding and electroplating, in order to ensure the bonding strength between the base 1 and the automobile counterpart, the other end of the base 1 in the third direction Z is bonded with a double-sided adhesive layer 3, and the thickness of the double-sided adhesive layer is between 0.5mm-1mm. Preferably, in the embodiment, the thickness of the double-sided adhesive layer 3 is 0.8mm, and the thickness of the double-sided adhesive layer 3 can be adaptively set according to the actual bonding requirement. Further, in order to improve the mounting precision between the whole automobile trademark plate and the automobile counterpart, the end of the base 1 away from the decorative cover 2 is provided with a positioning column 13 for connecting with the automobile counterpart, and the double-sided adhesive layer 3 is provided with a via hole through which the positioning column 13 passes.

[0033] The assembling process of the utility model is as follows: the hot melting column 21 on the decorative cover 2 is inserted into the corresponding through hole 12 on the base 1, at the same time, the decorative cover 2 is attached to the bottom of the limiting groove 11, the hot melting column 21 is melted by using hot riveting equipment or welding gun and then cooled, so that the decorative cover 2 is connected with the base 1 firmly, and then the double-sided adhesive layer 3 is pasted at the end of the base 1 away from the decorative cover 2.

[0034] In summary, the utility model embodiment provides an automobile trademark plate, the limiting groove 11 is formed at one end of the base 1 in the third direction Z, the decorative cover 2 is installed in the limiting groove 11, the positioning between the base 1 and the decorative cover 2 is accurate, the overall assembly efficiency of the automobile trademark plate is improved, in addition, the end of the decorative cover 2 towards the base 1 is provided with a plurality of hot melting columns 21, the limiting groove 11 is provided with the through hole 12 corresponding to the hot melting column 21, the base 1 and the decorative cover 2 are welded and fixed through the hot melting column 21 passing through the through hole 12, the connection strength of the base 1 and the decorative cover 2 is improved, the double-sided adhesive tape does not need to be customized according to the shape of the base 1 and the decorative cover 2, and the production cost of the automobile trademark plate is reduced.

[0035] The above only describes the preferred embodiments of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the utility model, and these improvements and replacements should also be regarded as the protection range of the utility model.
