Description

Technical Field

[0001] The utility model relates to the technical field of automobile component mounting brackets, in particular to a mounting bracket and a vehicle-mounted terminal device. Background Art

[0002] As a core component of the Internet of Vehicles system, TBOX (Telematics BOX, intelligent vehicle terminal) can realize communication and data exchange between vehicles and cloud and mobile applications. It can not only provide functions such as remote vehicle control, status monitoring and fault diagnosis, but also provide car owners with more convenient and personalized information services. These advantages make TBOX an indispensable key component of intelligent networked vehicles.

[0003] At present, most vehicle-mounted terminal devices rely on metal mounting brackets for fixation. If the metal brackets are not properly treated with rust prevention, they will corrode and rust in harsh environments (such as encountering condensation, water vapor, or rain during transportation), which may weaken the structural strength of the brackets, thereby affecting the stability and safety of the vehicle-mounted terminal devices. In addition, existing metal brackets need to be assembled from multiple parts. The more parts there are, the higher the error rate in the assembly process. Each additional part means that every step in the production and assembly line requires extra attention, making it difficult to ensure the accuracy and completeness of the metal bracket after assembly. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the first purpose of the utility model is to propose a mounting bracket, which adopts an integrated non-metallic structure design, which not only avoids rust and corrosion, and ensures the stability and safety of the vehicle-mounted terminal device after installation. At the same time, the mounting bracket itself does not require assembly, which simplifies the production process, reduces the error rate, and greatly improves the stability and integrity of product quality.

[0006] The second objective of the present application is to provide a vehicle-mounted terminal device.

[0008] The mounting bracket of the utility model utilizes the design of an integrated structure between the first leg, the lower shell and the second leg, so that the three form an integral structure with higher firmness. In the production process, there is no need to splice and assemble the first leg, the lower shell and the second leg, which simplifies the production process and effectively reduces the risk of errors caused by manual splicing, thereby greatly improving the stability and integrity of product quality. At the same time, the first leg, the lower shell and the second leg are made of PP+GF40 material, which has the advantages of corrosion resistance, rust resistance, small size and light weight compared with traditional metal brackets, thereby solving the problem that metal brackets are prone to rust and corrosion in humid or harsh environments, ensuring the long-term durability of the mounting bracket and improving the stability and safety of the device body when supporting it.

[0009] In addition, the mounting bracket proposed in the application may also have the following additional technical features:

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] The following describes the mounting bracket and the vehicle-mounted terminal device according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, the mounting bracket of the embodiment of the utility model may include a lower shell 1 , a first leg 2 and a second leg 3 .

[0030] The first leg 2 and the second leg 3 are integrally formed on the lower shell 1 , and the first leg 2 and the second leg 3 are arranged opposite to each other, and the first leg 2 , the lower shell 1 and the second leg 3 form an inverted "X" structure.

[0031] Among them, it can be understood that the first leg 2, the lower shell 1 and the second leg 3 form an inverted "X"-shaped structure, which can form a U-shaped installation cavity, so that the device body 100 is surrounded on three sides (the lower surface and two side surfaces of the device body 100) during installation, thereby being able to limit the device body 100 and further improving the stability of the device body 100 when supporting it.

[0032] The lower shell 1, the first leg 2 and the second leg 3 are all made of PP+GF40 material.

[0033] It should be noted that the PP+GF40 material described in this embodiment is 40% glass fiber reinforced polypropylene, which is a high-quality composite material that combines the matrix properties of polypropylene (PP) and the reinforcing properties of glass fiber (GF). It has the characteristics of high strength and rigidity, heat resistance, and corrosion resistance. It can be made into products of various shapes through molding processes such as injection molding and extrusion. It has good machinability, thereby avoiding rust and corrosion. It not only improves the service life of the lower shell 1, the first leg 2 and the second leg 3, but also improves the stability and firmness of the device body 100 when supporting it.

[0034] A first flange 20 and a second flange 21 are bent at the top end of the first leg 2 , and a third flange 30 is bent at the top end of the second leg 3 .

[0035] Among them, it can be understood that by providing the first flange 20, the second flange 21 and the third flange 30, the contact area of ​​the first leg 2 and the second leg 3 when installed in a specific position of the vehicle (for example, above the co-pilot's glove box, below the center console or below the air outlet of the instrument panel, etc., depending on the personalized layout of different models) can be increased. At the same time, the first flange 20, the second flange 21 and the third flange 30 form a three-point support, which can effectively disperse the force points, thereby improving the stability and firmness of the mounting bracket during installation.

[0036] As a possible situation, in order to further improve the supporting strength and anti-warping ability of the first flange 20, the second flange 21 and the third flange 30, a plurality of equidistantly arranged triangular reinforcing ribs may be provided near the bending points on the inner sides of the first flange 20, the second flange 21 and the third flange 30.

[0037] Specifically, the design of the integrated structure between the first leg 2, the lower shell 1 and the second leg 3 enables the first leg 2, the lower shell 1 and the second leg 3 to form an integral structure with higher firmness. During the production process, there is no need to splice and assemble the first leg 2, the lower shell 1 and the second leg 3, which simplifies the production process and effectively reduces the risk of errors caused by manual splicing, thereby greatly improving the stability and integrity of product quality.

[0038] Furthermore, the first leg 2, the lower shell 1 and the second leg 3 are made of PP+GF40 material, which has the advantages of corrosion resistance, rust resistance, small size and light weight compared to traditional metal brackets. It solves the problem that metal brackets are prone to rust and corrosion in humid or harsh environments, ensures the durability of the mounting bracket, and improves the stability and safety of the device body 100 when supporting it. At the same time, its lightweight material characteristics reduce the weight of the entire vehicle.

[0039] In one embodiment of the present invention, Figure 3As shown, the first flange 20 and the third flange 30 are flush, and the height from the upper vertex of the first flange 20 to the lower surface of the lower shell 1 is h1 mm.

[0040] It should be noted that the upper vertex position of the first flange 20 described in this embodiment refers to the position at the highest point on the first flange 20 .

[0041] The height of the lower shell 1 is h2mm, wherein the height range of h1 is 77-79mm, and the height range of h2 is 10-11mm. It can be understood that, for example, the height of h1 can be 78, 78.5, etc., and the height of h2 can be 10.5, 10.6, 10.7, etc.

[0042] Specifically, by setting the height of the mounting bracket within a reasonable range, it is possible to meet the installation and support requirements for the device body 100 and the compact size design, thereby reducing the space occupied by the mounting bracket and optimizing the space layout.

[0043] In one embodiment of the present invention, Figure 1 As shown, a plurality of first reinforcing ribs 4 arranged in a crisscross pattern are provided in the downwardly concave cavity of the lower shell 1 , and the height of the first reinforcing ribs 4 is smaller than the height of the cavity of the lower shell 1 .

[0044] Specifically, by providing a plurality of first reinforcing ribs 4 arranged in a criss-cross pattern, the overall rigidity of the lower shell 1 can be increased, so that the shell is not easily deformed or twisted when subjected to external force, thereby ensuring the service life of the mounting bracket. Moreover, by reasonably designing the layout and size of the first reinforcing ribs 4, the manufacturing cost can be reduced while ensuring the structural strength, while achieving the purpose of lightweighting.

[0045] Among them, the reasonable layout of the first reinforcing ribs 4 can simulate the deformation and stress of each part in the lower shell 1 through overall simulation analysis, so as to increase the number and height of the first reinforcing ribs 4 according to the results, thereby improving the overall strength and reducing the overall deformation of the mounting bracket during injection molding.

[0046] In one embodiment of the present invention, Figure 1 As shown, the first flange 20, the second flange 21 and the third flange 30 are all provided with a downwardly recessed accommodating cavity (not marked in the figure), and a screw hole (not marked in the figure) is provided in the accommodating cavity.

[0047] Specifically, by providing a screw hole connector, it is convenient to fix the mounting bracket in a specific position with a matching connector (such as a bolt, a screw, etc.), and the design of the accommodating cavity can reduce material consumption and manufacturing costs while achieving the purpose of lightweighting.

[0048] In one embodiment of the present invention, Figure 1 As shown, the first flange 20 , the second flange 21 and the third flange 30 are bent in a direction away from the lower shell 1 , respectively, and the bending directions of the first flange 20 and the second flange 21 are perpendicular.

[0049] Specifically, through the above design, when the device body 100 is installed from top to bottom, it will not be affected by the first flange 20, the second flange 21 and the third flange 30, thereby improving the installation efficiency and accuracy of the device body 100, and making it more convenient to install the connecting parts. At the same time, the bending directions of the first flange 20 and the second flange 21 are vertical, which can more effectively resist the effect of torsional force. The connecting parts on the first flange 20 and the second flange 21 can support each other and jointly resist torsional deformation, thereby improving the overall torsional resistance.

[0050] In one embodiment of the present invention, Figure 2 As shown, conical positioning columns 31 are respectively provided on the downwardly disposed surfaces of the first flange 20 and the third flange 30 .

[0051] Specifically, the design of the tapered positioning column 31 enables the mounting bracket to more easily find and accurately snap into the preset rectangular groove when docking with the external mounting position, thereby ensuring the accurate positioning of the mounting bracket. The tapered structure has a guiding effect during the insertion process, reducing the difficulty of alignment during installation and improving installation efficiency.

[0052] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a plurality of second reinforcing ribs 5 and a plurality of third reinforcing ribs 6 are provided on the lower shell 1, and a plurality of fourth reinforcing ribs 7 arranged at equal distances are provided on the first leg 2 and the second leg 3 respectively.

[0053] Specifically, an overall simulation analysis is performed on the mounting bracket, and a second reinforcement rib 5, a third reinforcement rib 6 and a fourth reinforcement rib 7 are set at appropriate positions to improve the overall strength and deformation resistance of the mounting bracket. At the same time, the biggest problem of the "J"-shaped structure is warping. Through overall simulation analysis and calculation, while ensuring that the structure is ultra-thin and the dimensional tolerance is within the required range, the fourth reinforcement rib 7 is set to effectively disperse the stress concentration area, thereby significantly reducing the risk of warping and deformation.

[0054] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a plurality of threaded holes 8 are arranged in the cavity of the lower shell 1, a plurality of ferrules 9 are arranged on the lower surface of the lower shell 1, and the plurality of ferrules 9 are arranged coaxially corresponding to the plurality of threaded holes 8 one by one.

[0055] It should be noted that the positions of the multiple threaded holes 8 in this embodiment correspond one-to-one to the positions of the threaded holes on the shell of the device body 100, so that when the device body 100 is docked on the lower shell 1, the device body 100 can be quickly fixed to the lower shell 1 directly through connecting parts (such as bolts), and the provision of a ring 9 can cover and shield the outer ring of the connecting part, thereby improving the overall aesthetics.

[0056] At the same time, the presence of the ferrule 9 also provides a clear installation position for the connector, making the installation process smoother.

[0057] In one embodiment of the present invention, Figure 1 As shown, the wall thicknesses of the lower housing 1 , the first leg 2 and the second leg 3 are the same.

[0058] Specifically, the design of the same wall thickness of the three makes the strength performance more balanced when bearing external loads. It helps to reduce the local stress concentration problem caused by uneven wall thickness and improve the overall stability and durability of the entire structure. At the same time, the uniform wall thickness makes the shrinkage rate relatively consistent, which helps to reduce the internal stress and deformation caused by uneven shrinkage, thereby improving the service life of the mounting bracket.

[0059] Please refer to Figure 4 The vehicle-mounted terminal device of the second embodiment of the present application includes a device body 100 and the above-mentioned mounting bracket, and the device body 100 can be detachably connected to the mounting bracket.

[0060] It should be noted that the explanation of the aforementioned mounting bracket embodiment is also applicable to the vehicle-mounted terminal device of this embodiment, and will not be elaborated here.

[0061] In summary, the mounting bracket and vehicle-mounted terminal device of the embodiments of the present application adopt an integrated non-metallic structure design, which not only avoids rust and corrosion, ensures the stability and safety of the vehicle-mounted terminal device after installation, but also the mounting bracket itself does not require assembly, simplifies the production process, reduces the error rate, and greatly improves the stability and integrity of product quality.
