In related technologies, because T-BOX is generally integrated with an antenna, it is usually installed on the roof of the vehicle to ensure optimal network performance.

[0003] However, when the vehicle is in a bumpy state, the roof is prone to twisting, which causes the housing of the T-BOX vehicle terminal equipment to deform, causing friction between the housing and the circuit board, thus producing abnormal noise. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0020] Reference Figure 1 This application illustrates a vehicle-mounted terminal device housing, which may specifically include: Circuit board storage slot 3 is used to store circuit boards; A support column assembly 4 is disposed on the inner wall of the circuit board storage slot 3. The support surface of the support column assembly 4 abuts against one side of the circuit board to support the circuit board. The reinforcing column assembly 5 is disposed on the inner wall of the circuit board storage slot 3 and is used to support the circuit board storage slot 3; A limiting module 6 is disposed at the edge of the circuit board storage slot 3. The limiting module 6 abuts against the other side of the circuit board and is used to limit the movement range of the circuit board.

[0021] In this embodiment, the vehicle-mounted terminal device housing 1 can be a T-BOX (Telematics-BOX) housing. This housing includes a circuit board storage slot 3 for storing circuit boards such as printed circuit boards (PCBs). A support column assembly 4 can be disposed on the inner wall of the circuit board storage slot 3, abutting against one side of the circuit board to support it. A reinforcing column assembly 5 can be disposed on the inner wall of the circuit board storage slot 3 to support it and enhance the hardness and strength of the wall surface. The height of the reinforcing column assembly 5 is lower than that of the support column assembly 4. A limiting module 6 can be disposed at the edge of the circuit board storage slot 3.

[0022] When the circuit board is placed into the circuit board storage slot 3, such as Figure 1 As shown, one side of the circuit board abuts against the support column assembly 4 of the circuit board storage slot 3, and the other side of the circuit board abuts against the contact surface of the limiting module 6. Through the support column assembly 4 supporting the circuit board and the limiting module 6 restricting the movement of the circuit board, the support column assembly 4 provides the necessary physical support for the circuit board, ensuring that the circuit board remains stable during installation and use. At the same time, the support column assembly 4 and the limiting module 6 support and restrict different sides of the circuit board respectively, ensuring that the circuit board will not bend or move due to external forces, so that the circuit board will be completely fixed in the circuit board storage slot 3.

[0023] In some embodiments of this application, the support column assembly 4 and the reinforcing column assembly 5 are arranged around the inner wall of the circuit board storage slot 3. By surrounding the inner wall of the circuit board storage slot 3 with the support column assembly 4, the positions of the support column assembly 4 are distributed, so that each area of ​​the circuit board storage slot 3 can support the circuit board, preventing the circuit board from shaking due to insufficient support on one side. At the same time, it helps to distribute the pressure applied to the circuit board and reduce the risk of bending due to local stress concentration.

[0024] By surrounding the inner wall of the circuit board storage slot 3 with reinforcing column assemblies 5, and by dispersing the positions of the reinforcing column assemblies 5, the entire inner wall of the circuit board storage slot 3 can be supported, preventing deformation or damage to part of the inner wall of the circuit board storage slot 3 due to external pressure.

[0025] In some embodiments of this application, such as Figures 1 to 3 As shown in the figure, the direction of the X-axis shown in the figure is denoted as the long side direction, and the direction pointed to by the Y-axis shown in the figure is denoted as the wide side direction. The support column assembly 4 includes a first support column 11 and a second support column 12. The first support column 11 is disposed on the inner wall of the circuit board storage slot 3 in the long side direction, and the second support column 12 is disposed on the inner wall of the circuit board storage slot 3 in the wide side direction.

[0026] By setting the first support post 11 in the support post assembly 4 on the inner wall of the circuit board storage slot 3 along its long side, and setting the second support post 12 on the inner wall of the circuit board storage slot 3 along its wide side, for example, it can be as follows: Figure 1 As shown, the first support column 11 is placed on the inner wall of the lower side of the circuit board storage slot 3, and the second support column 12 is placed on the inner wall of the right side of the circuit board storage slot 3. Placing the support column assembly 4 on the inner wall of the circuit board storage slot 3 in different directions can effectively disperse the pressure applied to the circuit board by vehicle bumps.

[0027] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the reinforcing column assembly 5 includes a first reinforcing column 21 and a second reinforcing column 22. The first reinforcing column 21 and the first supporting column 11 are located on the same inner wall, and the second reinforcing column 22 and the second supporting column 12 are located on the same inner wall.

[0028] The first reinforcing column 21 of the reinforcing column assembly 5 is set on the inner wall of the same side as the first support column 11, and the second reinforcing column 22 is set on the inner wall of the same side as the second support column 12. By dispersing the positions of the reinforcing columns, multiple inner walls of the circuit board storage slot 3 can be supported, so that while the support column assembly 4 supports the circuit board stably, the hardness and strength of the circuit board storage slot 3 are strengthened, and the stability of the circuit board storage slot 3 is improved.

[0029] In some embodiments of this application, such as Figures 3 to 5 As shown, the support column assembly 4 also includes a third support column 13, a fourth support column 14, a fifth support column 15, and a sixth support column 16.

[0030] The fifth support column 15 and the sixth support column 16 include a support surface 103 and a support back 104; the support surface 103 and the support back 104 intersect to form a right-angle intersection area.

[0031] The right-angle intersection area formed by the intersection of the support surface 103 and the support back 104 provides higher bending stiffness and strength when subjected to external forces perpendicular to the support surface 103 during vehicle bumps, making it more difficult for the fifth support column 15 and the sixth support column 16 to bend or break, thereby enhancing the stability of the overall structure.

[0032] The third support column 13 and the second support column 12 are located on the same inner wall, and the fourth support column 14 is located on the inner wall opposite to the first support column 11.

[0033] The fifth support column 15 and the sixth support column 16 are located on the inner wall of the second support column 12 on the opposite side.

[0034] In some embodiments of this application, the reinforcing column assembly 5 and the supporting column assembly 4 are alternately distributed on the inner wall of the same side, for example, such as Figure 4 and Figure 5 As shown, the reinforcing column assembly 5 also includes a third reinforcing column 23, a fourth reinforcing column 24, a fifth reinforcing column 25, a sixth reinforcing column 26, and a seventh reinforcing column 27.

[0035] The third reinforcing column 23, the fourth reinforcing column 24, the fifth reinforcing column 25 and the fourth supporting column 14 are located on the same side of the inner wall, and the sixth reinforcing column 26 and the seventh reinforcing column 27 are alternately distributed on the same side of the inner wall with the fifth supporting column 15 and the sixth supporting column 16.

[0036] By alternating the distribution of support column assembly 4 and reinforcing column assembly 5 on the inner wall of the same side, the support column assembly 4 can stabilize the circuit board while strengthening the hardness and strength of the circuit board storage slot 3, thereby improving the stability of the circuit board storage slot 3.

[0037] In some embodiments of this application, the limiting module 6 includes two limiting posts 7, which are arranged diagonally along the circuit board storage slot 3.

[0038] For example, it can be like Figure 1 As shown, two limiting posts 7 are positioned diagonally along the circuit board storage slot 3. One limiting post is located inside the lower left corner of the circuit board storage slot 3, and the other is located inside the upper right corner of the circuit board storage slot 3. By setting them diagonally along the circuit board storage slot 3, the limiting of the circuit board can be balanced, ensuring that both sides of the circuit board are restricted from movement. Those skilled in the art can determine the specific position of the limiting module 6 according to actual design requirements, and no further limitations are made here.

[0039] In some embodiments of this application, the limiting module 6 may further include two connecting posts 41, wherein the connecting posts 41 are provided with threaded holes, and the two connecting posts 41 are arranged diagonally along the circuit board storage slot.

[0040] For example, it can be like Figure 1 As shown, the two connecting posts 41 can be positioned diagonally opposite each other in the circuit board storage slot 3. One connecting post is located inside the upper left corner of the circuit board storage slot 3, and the other connecting post is located inside the lower right corner of the circuit board storage slot 3. When the circuit board is placed in the circuit board storage slot 3, the pre-set threaded holes on the circuit board can be aligned with the threaded holes on the connecting posts 41, and connected by the first screw. The circuit board is further fixed in the circuit board storage slot 3 by the screw, which can prevent the circuit board from shifting due to vibration or impact when the vehicle experiences severe bumps.

[0041] In some embodiments of this application, such as Figure 6 As shown, the limiting post 7 includes a fixing rod 101 and a hook portion 102. One end of the fixing rod 101 is connected to the circuit board storage slot 3, and the other end is connected to the hook portion 102. The angle between the contact surface of the hook portion 102 and the side surface of the fixing rod 101 is greater than 90 degrees.

[0042] One end of the fixing rod 101 is connected to the circuit board storage slot 3, and the other end of the fixing rod 101 is connected to the hook part 102. The fixing rod 101 is used to fix the position of the limiting post 7, and the contact surface of the hook part 102 near the end of the circuit board storage slot 3 is used to abut against one side of the circuit board. By abutting against the circuit board with the contact surface of the hook part 102, the movement of the circuit board can be restricted.

[0043] For example, such as Figure 6 As shown, with the height direction of the circuit board storage slot 3 as the height and the width direction of the fixed rod 101 connecting the circuit board storage slot 3 as the base, a cross surface θ is constructed. The cross surface θ cuts off the cross surface of one of the limiting posts 7. After cutting the cross surface, it is as follows: Figure 7 As shown, the tangential angle β at the connection between the conventional hook portion 102 and the fixing rod 101 is generally set to a right-angled bent structure. By embedding the circuit board into the right angle, a stable surface contact fixing structure can be formed. In order to minimize contact inside the circuit board storage slot 3 and reduce the risk of frictional noise, the probability of contact friction can be reduced by achieving a smaller contact area. For example, as... Figure 7As shown, the tangential angle β at the connection between the hook portion 102 and the fixing rod 101 is set to an obtuse angle greater than 90°, so that the other side of the circuit board makes line contact with one side of the hook portion 102 (the side of angle β). This optimizes the traditional surface contact into a line contact, reducing the contact area and thus reducing the risk of friction and the probability of abnormal noise. The obtuse angle can be set to 95°-100°. Those skilled in the art can further determine the obtuse angle based on the actual design requirements and the position of the line contact, without making further limitations here. The height of the fixing rod 101 described in this application can be adjusted. By maintaining the original height of the hook portion 102 and extending the height of the fixing rod 101, and setting the tangential angle β at the connection between the hook portion 102 and the fixing rod 101 to an acute angle less than 90°, the other side of the circuit board makes line contact with one side of the hook portion. This also optimizes the traditional surface contact into a line contact, reducing the contact area and thus reducing the risk of friction and the probability of abnormal noise. The specific acute angle can be set to 75° or 85°. Those skilled in the art can further determine the obtuse angle based on the actual design requirements and the position of the line contact, without making further limitations here.

[0044] In some embodiments of this application, for example, such as Figure 2 and Figure 8 As shown, the support surface of the support column assembly 4 is provided with a first anti-friction coating 301, which is used to reduce the coefficient of friction between the support column assembly 4 and the circuit board.

[0045] In some embodiments, the first anti-friction coating 301 may be a coating material that reduces the coefficient of friction between the support surface of the support column assembly 4 and one side of the circuit board.

[0046] In one embodiment of this application, for example, such as Figure 8 As shown, a second anti-friction coating 302 is provided on the outer edge of the side of the vehicle terminal equipment housing 1 near the closed housing 2, which is used to reduce the coefficient of friction between the vehicle terminal equipment housing 1 and the closed housing 2.

[0047] In this embodiment of the application, when the splicing is completed, inside the T-BOX, the support column assembly 4 and the circuit board will inevitably have a contact surface, and the vehicle terminal equipment housing 1 and the closed housing 2 will inevitably have a contact area. This contact area is located in the area of ​​the vehicle terminal equipment housing 1 near the outer edge of the side of the closed housing 2. Therefore, for these places where there is inevitable contact, a first anti-friction coating 301 and a second anti-friction coating 302 will be provided to reduce friction, so that the static friction coefficient of the places where there is inevitable contact is reduced.

[0048] In some embodiments of this application, phosphor is provided in the first anti-friction coating 301 and the second anti-friction coating 302.

[0049] In practical applications, the coating material for the friction-reducing coating is usually dry film lubricant D96. The color of this material is similar to that of the vehicle terminal housing 1. After the coating is applied, it is not possible to visually inspect whether the operation is in accordance with the requirements. Therefore, fluorescent powder is added to the coating material. Through the fluorescence reaction of the fluorescent powder, it is easier to inspect whether the coating material completely covers the contact area.

[0050] In some embodiments of this application, the anti-friction coating 301 is provided with pigment.

[0051] In some embodiments of this application, the vehicle terminal device housing 1 is made of fiberglass and / or plastic materials.

[0052] The fiberglass material can be a fiber material made of glass, usually made by drawing molten glass into filaments through fine holes, and the plastic material can be a material with a high molecular polymer as the main component.

[0053] In this embodiment, the root cause of the TBOX noise lies in the incompatibility between the material of the vehicle terminal device housing 1 and the material of the enclosed housing, which easily leads to noise. Furthermore, since the TBOX is installed on the roof of the vehicle, where the ambient temperature is high, the TBOX material requires a high temperature resistance of 85°C and a relative humidity of 85%. Additionally, certain requirements are placed on the flame-retardant properties of the plastic material. Therefore, the vehicle terminal device housing 1 can be made by fusing 30% fiberglass material with plastic material to form a composite material. The specific content of fiberglass material can be determined by those skilled in the art based on actual design requirements, and is not limited here.

[0054] The vehicle terminal equipment housing 1 is made of composite material, including glass fiber and plastic. By using composite material for the vehicle terminal equipment housing 1, the vehicle terminal equipment housing 1 has high strength and corrosion resistance. At the same time, the composite material can effectively improve the wear resistance of the vehicle terminal equipment housing 1, thereby reducing the abnormal noise caused by squeezing friction between the housings and between the housing and the contents when deformation occurs.

[0055] like Figure 1 and Figure 9 As shown, another vehicle-mounted terminal device housing of this application is illustrated, which may specifically include: The vehicle-mounted terminal device 1 includes a fitting groove 43, which is located in the circuit board storage groove 3 along the long side direction, and a fitting groove hole 44 is provided on the fitting groove 43. The enclosed housing 2 includes a threaded connection hole 201 and a fitting plate 202. The fitting plate 202 is located along the long side of the enclosed housing 2, and a fitting hole 203 is provided on the fitting plate 202. The threaded connection hole 201 and the threaded hole on the connecting post 41 of the vehicle terminal equipment housing 1 are opposite to the threaded through hole of the circuit board, and the closed housing 2 and the circuit board are further fixed to the vehicle terminal equipment housing 1 with screws.

[0056] The fitting plate 202 will be embedded in the fitting groove 43 of the vehicle terminal equipment housing 1. The fitting hole 203 and the fitting groove hole 44 are opposite to each other, and the fitting screw is used to connect the fitting groove hole 44 through the fitting hole 203.

[0057] In this embodiment of the application, during assembly, the fitting plate 202 of the closed housing 2 is accurately inserted into the fitting groove 43 of the vehicle terminal equipment housing 1, so that the fitting hole 203 is opposite to the fitting groove hole 44, and then the two are fixed together by fitting screws.

[0058] In this utility model application, by providing a fitting groove 43 to the vehicle terminal equipment housing 1 and a fitting plate 202 to the closed housing 2, during the installation and connection process, the fitting plate 202 of the closed housing 2 is accurately inserted into the fitting groove 43 of the vehicle terminal equipment housing 1, so that the fitting hole 203 is aligned with the fitting groove hole 44, and then the two are fixed together by fitting screws, which can effectively improve the assembly efficiency and ensure that the two are more firmly fixed and will not deform.

[0059] Reference Figure 1 and Figure 10 This illustrates another vehicle-mounted terminal device provided in this application, which may further include: The vehicle-mounted terminal equipment housing 1 includes mounting ears 42 and multiple reinforcing plates 401; The mounting ear 42 has a mounting hole 50; In this embodiment, a reinforcing plate 401 is provided between the mounting ear 42 and the vehicle-mounted terminal equipment housing 1. The reinforcing plate 401 can be triangular, and the triangular reinforcing plate 401 has a stabilizing effect, which can prevent the mounting ear 42 from deforming during installation and affecting the installation accuracy. The mounting ear 42 is provided with a mounting hole 50. In actual use, the vehicle-mounted terminal equipment housing 1 of this utility model is fixed to the car by screws passing through the mounting holes 50 on the mounting ear 42.

[0060] In some embodiments of this application, the circuit board is an antenna circuit board, and the vehicle-mounted terminal device is mounted on the roof of the vehicle.

[0061] In this embodiment, the circuit board can be configured as an antenna circuit board for transmitting and receiving radio signals. To ensure optimal network performance, the vehicle-mounted terminal device can be installed on the vehicle roof.

[0062] This utility model discloses a vehicle-mounted terminal device housing, comprising a circuit board storage slot, a support column assembly disposed on the inner wall of the circuit board storage slot, the support surface of the support column assembly abutting against one side of the circuit board, a reinforcing column assembly disposed on the inner wall of the circuit board storage slot, and a limiting module. The structure is simple, easy to assemble, and has high mechanical strength. The minimal internal structure protects key components within the vehicle-mounted terminal device, ensuring normal operation. Furthermore, the inclusion of reinforcing components such as mounting ears firmly secures the vehicle-mounted terminal device housing when the vehicle is moving and experiencing bumps, reducing the probability of deformation between the housing and the enclosed shell, which could cause friction between the housing and its contents, thus eliminating abnormal noise.

[0063] For example, in the embodiments of this utility model, the vehicle may include a small car, a medium-sized car, a sedan, a truck, a trailer, a CDV (Car Derived Van), an MPV (multi-Purpose Vehicle), an SUV (Sport Utility Vehicle), etc. The specific type of vehicle is not limited in the embodiments of this application.

[0064] As the device embodiment is basically similar to the method embodiment, the description is relatively simple, and relevant parts can be found in the description of the embodiment.

[0065] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
