Technical Field

[0001] This utility model relates to the field of HUD communication, and in particular to a wire harness integration box. Background Technology

[0002] HUD—Head-Up Display, also known as a head-up display system, projects current driving information, such as vehicle speed and RPM, onto a virtual display screen at a certain distance in front of you through the windshield.

[0003] Before a HUD can be used, it needs to be tested using a HUD testing fixture. During testing, the HUD testing fixture sends commands to the HUD control board via an industrial control computer. The control board then controls the projector's actions according to these commands, such as projecting, slicing, flipping, and adjusting brightness, to ensure a clear image projected onto the windshield. Throughout this process, the control board communicates with the industrial control computer and the projector via wiring harnesses.

[0004] However, different HUDs have different communication connection methods between the projector and the corresponding control board, such as Lin, Can, and Canfd communication connections. When HUD testing fixtures test HUDs with different communication connection types, multiple types of HUDs occupy a lot of space and require frequent installation of control boards, corresponding projectors, and industrial control computers, making it difficult to achieve fast switching and stable connection.

Adjacent control box bodies are detachably connected. The control box body is used to accommodate a control board. Each layer of the control board is connected to a first wire harness and a second wire harness. Each of the control boxes is provided with a docking through hole, which allows the first wire harness to communicate with the industrial control computer after passing through itself. Each of the control boxes has a through-hole wire harness slot along the first direction.

[0010] In one embodiment, a clamping hole is provided at the connection between the first clamping rod and the second clamping rod, and the clamping hole is positioned opposite to the connecting through hole.

[0011] In one embodiment, one of the two adjacent control boxes is provided with a limiting groove, and the other is provided with a mating protrusion.

[0012] In one embodiment, the wire harness integration box includes a bottom integration box disposed at the bottom of the control box group. The bottom integration box has an output through hole, which allows the second wire harness in the last layer of the wire harness slot to pass through and communicate with the projector.

[0013] In one embodiment, the wire harness integration box further includes a wire harness aggregator disposed in the bottom integration box, the wire harness aggregator having a wire harness integration hole disposed opposite to the output through hole.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this application provides a wire harness integration box 10, which is applied in a HUD testing fixture 20. The wire harness integration box 10 includes a control box assembly 100, which includes a plurality of control box bodies 110 stacked sequentially along a first direction a, preferably a vertical direction.

[0033] The two adjacent control boxes 110 are detachably connected. The control box 110 is used to house the control board, and each layer of the control board is connected to a first wiring harness and a second wiring harness. In actual use, multiple control boxes 110 can be used to house control boards of HUD products with various communication connection types. The number of control boxes 110 can be 2, 3, 5 or more, and the specific number is not limited.

[0034] Each control box 110 has a through hole 1121, through which the first wiring harness passes and communicates with the industrial control computer. That is, the first wiring harness of each control board communicates with the industrial control computer through the through hole 1121. In a specific setup, the industrial control computer is also electrically connected to the electrical cabinet, and the industrial control computer sends power and input commands to the control board through the first wiring harness.

[0035] Each control box 110 has a through-hole wire harness slot 1111 along the first direction a. The last wire harness slot 1111 is used to integrate the second wire harness of the same layer and the second wire harness of the upper layer, which then communicate with the projector. That is, the second wire harness of the control board is uniformly integrated to the end of the control box group 100 through the wire harness slot 1111. It should be noted that the second wire harness includes video cables and control cables. The video cables are used to control the projection output of the projector, and the control cables are used to control the projector's flipping and other action commands. For classified storage, each control box 110 has two wire harness slots 1111, which respectively accommodate the video cable and the control cable. In specific settings, the two wire harness slots 1111 in the same layer are symmetrically arranged about the center line of the control box 110.

[0036] The aforementioned wiring harness integration box 10, by setting up multiple control boxes 110 stacked sequentially, can accommodate control boards for various communication connection types of HUD products within the multiple control boxes 110, thus improving the utilization and tidiness of the HUD testing fixture 20's work surface. Furthermore, the first wiring harness of each control board communicates with the industrial computer through corresponding mating through holes 1121, and the second wiring harness of the control board is integrated into the bottom of the control box assembly 100 through wiring harness slots 1111. When different types of HUD products need to be tested, the communication connection method compatible with the projector can be selected from the aggregated second wiring harness, thereby enabling rapid switching of the testing object and ensuring connection stability.

[0037] It is important to emphasize that the control board contains a power supply chip. To ensure heat dissipation of the chip, in a preferred embodiment, the control box 110 includes a first bottom wall 111 and a first side wall 112 connected to the first bottom wall 111. The first bottom wall 111 has a wire harness groove 1111, and the first side wall 112 has a docking through hole 1121 and a plurality of first heat dissipation through holes 1122, which are spaced apart. In a specific configuration, the first side wall 112 is preferably a hollow rectangular frame, and the first heat dissipation through holes 1122 are formed on opposite sides of the hollow rectangular frame. The length extension direction of the first heat dissipation through holes 1122 is parallel to the first direction a, and the shape of the first heat dissipation through holes 1122 is preferably an oblong hole. To meet the dustproof requirements of the control board, the number of first heat dissipation through holes 1122 on the same side is preferably five, but not limited to five, and can be set according to the size of the control box 110. In this case, to increase heat dissipation without affecting dustproofing, a fan can be added to the control box 110. To ensure that the connection between the first wiring harness and the industrial control computer does not affect the heat dissipation requirements, the mating through hole 1121 and the first heat dissipation through hole 1122 are set on opposite sides.

[0038] Combination Figure 4 , Figure 5 and Figure 6As shown, in order to prevent the first wire harness from shaking randomly, the control box 110 also includes a clamping member 120 disposed on the first side wall 112. The clamping member 120 has a clamping groove 123 that is directly opposite to the docking through hole 1121. In actual use, the first wire harness passes through the clamping groove 123 and the docking through hole 1121 in sequence and then communicates with the industrial control computer. The clamping groove 123 is used to limit the first wire harness.

[0039] To facilitate the design of the clamping member 120 for limiting the first wire harness, more specifically, the clamping member 120 includes a first clamping rod 121 and a second clamping rod 122 disposed on the first side wall 112. In a specific configuration, the first clamping rod 121 and the second clamping rod 122 are respectively provided with a first fixing through hole 1211 and a second fixing through hole 1221. Two fasteners pass through the first fixing through hole 1211 and the second fixing through hole 1221 respectively to detachably connect the first clamping rod 121 and the second clamping rod 122 to the first side wall 112. The fasteners can be bolts, screws, or other components. Furthermore, the first clamping rod 121 and the second clamping rod 122 are connected at a preset angle so that a clamping groove 123 is formed between the first clamping rod 121 and the second clamping rod 122. The clamping groove 123 is preferably a V-shaped structure, but is not limited to the above-mentioned V-shape, and can be any geometric shape. With the above settings, when the first wire harness passes through the clamping groove 123, the first clamping rod 121 and the second clamping rod 122 play a positioning and limiting role on the first wire harness, which can effectively prevent the first wire harness from shaking randomly.

[0040] by Figure 4 For example, the opening of the V-shaped clamping groove 123 faces the first heat dissipation through hole 1122 on the right. It should be noted that during specific installation, the opening of the V-shaped clamping groove 123 can also face the first heat dissipation through hole 1122 on the left, so as to scale the clamping groove 123 for clamping the first wire harness, which is beneficial to fix the first wire harness in the middle position of the mating through hole 1121.

[0041] To avoid damaging the first wire harness, the clamping member 120 is preferably made of soft rubber. It should be emphasized that when the first wire harness is thin, the clamping groove 123 may have difficulty clamping it. Therefore, more specifically, a clamping hole 124 is provided at the connection between the first clamping rod 121 and the second clamping rod 122, and the clamping hole 124 is directly opposite the mating through hole 1121. With this arrangement, the thinner first wire harness can be fixed and limited through the clamping hole 124.

[0042] To facilitate a detachable connection between two adjacent control boxes 110, in a preferred embodiment, one of the two adjacent control boxes 110 is provided with a limiting groove 113, and the other is provided with a mating protrusion 114. This arrangement facilitates the individual disassembly or overall assembly of each adjacent hierarchical structure within the control box assembly 100.

[0043] To facilitate the connection of the second wiring harness integrated at the bottom of the control box assembly 100 to the corresponding projector, in a preferred embodiment, the wiring harness integration box 10 includes a bottom integration box 200, which is disposed at the bottom of the control box assembly 100. The bottom integration box 200 has an output through hole 221, through which the second wiring harness in the last layer wiring harness slot 1111 passes and communicates with the projector. In a specific configuration, the bottom integration box 200 includes a second bottom wall 210 and a second side wall 220 connected to the second bottom wall 210. The second side wall 220 has an output through hole 221. With the above configuration, the second wiring harness located at the bottom of the control box assembly 100 connects to the projector from the side upward through the output through hole 221, facilitating the docking operation for workers.

[0044] To enhance the overall heat dissipation of the wire harness integration box 10, the second side wall 220 is also provided with a plurality of spaced second heat dissipation through holes 222. The second side wall 220 is preferably a hollow rectangular frame, and the second heat dissipation through holes 222 and the output through holes 221 are arranged on opposite sides.

[0045] Combination Figure 7 As shown, to stabilize the second wire harness, the wire harness integration box 10 further includes a wire harness aggregator 300 disposed in the bottom integration box 200. The wire harness aggregator 300 has a wire harness integration hole 332 disposed opposite to the output through hole 221. In actual use, the second wire harness passes through the wire harness integration hole 332 and the output through hole 221 in sequence to communicate with the projector. The wire harness integration hole 332 is used to limit the second wire harness.

[0046] In a specific configuration, the wire harness aggregator 300 includes a base 310, a hook 320, and a flip cover 330. The base 310 is located on the second bottom wall 210 of the bottom integrated box 200. During installation, the base 310 is attached to the second bottom wall 210 with an adhesive layer, such as double-sided tape. The above configuration facilitates the adjustment of the position of the wire harness aggregator 300. The hook 320 is fixed on the base 310. One end of the flip cover 330 is rotatably mounted on one end of the base 310. In a specific setting, the flip cover 330 is pivotally connected to one end of the base 310 through the fixed shaft 340. The other end of the flip cover 330 is provided with a limiting hook 331 that is adapted to the hook 320. The limiting hook 331 is engaged with the hook 320. The flip cover 330 is provided with a wire harness integration hole 332.

[0047] With the above configuration, the wire harness integration hole 332 integrates and limits the second wire harness, and the flip cover 330 cooperates with the base 310 to complete the locking, thereby ensuring the stability of the second wire harness. In order not to damage the second wire harness, the wire harness aggregator 300 is preferably made of polyethylene, but not limited to polyethylene; any soft material is acceptable.

[0048] See again Figure 1 and Figure 4 To facilitate the detachable installation of the wiring harness integration box 10 and the HUD testing fixture 20, a limiting support seat 230 is provided at the corner of the bottom integration box 200. The limiting support seat 230 includes a docking plate 231 and an extension plate 232 connected to the docking plate 231. The docking plate 231 is L-shaped and connected to the corner of the bottom integration box 200. The extension plate 232 is detachably connected to the table panel 21 of the HUD testing fixture 20 by fasteners.

[0049] To improve the safety of the wiring harness integration box 10, in a preferred embodiment, the wiring harness integration box 10 further includes a top cover 400, which is rotatably disposed on the top control box 110. In a specific configuration, the top cover 400 is rotatably connected to the first side wall 112 of the top control box 110 via a hinge 500.

[0050] See again Figure 2 To enhance the connection stability between the top cover 400 and the top control box 110, the top cover 400 and the top control box 110 are further reinforced by a locking assembly 600. The locking assembly 600 includes a latch and a locking element adapted to the latch. One of the latch and the locking element is located on the side of the top cover 400 opposite to the hinge 500, and the other is located on the first side wall 112 of the top control box 110. It should be noted that the latch and locking element are a common plug-in type structure and will not be elaborated upon here. Through the above design, the top cover 400 will not open due to slight external force, ensuring the safety of the wiring harness integration box 10. To ensure both lightweight design and insulation, the wiring harness integration box 10 is entirely made of phenolic resin.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
