Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a mounting structure, instrument beam component, and method for a vehicle head-up display device. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the advancement and development of vehicles, in-vehicle head-up display (HUD) technology has become quite common. HUDs use the principle of optical reflection to project information such as navigation, vehicle speed, and tire pressure onto the windshield, making it easier for drivers to quickly understand the basic information of the vehicle and improving driving safety.

[0004] In existing technologies, HUD mounting structures are installed on sheet metal brackets on the instrument crossbeam, which requires high dimensional accuracy. Furthermore, previous HUD mounting brackets were constructed by welding together multiple brackets. (See [link to previous technology]). Figure 1 As shown, this type of mounting bracket typically includes a first mounting strip 1, a second mounting strip 2, a first U-shaped frame 3 mounted on the first mounting strip, and a second U-shaped frame 4 supported by the second mounting strip 2. A central support frame 6 is also provided between the first and second mounting strips. A mounting part 5 is provided on one side of the central support frame 6 for connection with the front compartment of the cab. The central support frame is also used for connection with the steering column. Obviously, there is a problem of structural complexity. The mounting strips on both sides of the HUD mounting bracket are installed separately, which makes it impossible to guarantee the installation difference of the mounting strips on both sides, and the dimensional accuracy cannot be controlled. This can easily cause the projection onto the windshield to deviate from the line of sight. On the other hand, the central support frame integrates the connection with the front compartment of the cab and the steering column, but the central support frame and the HUD mounting bracket are separate modules. There is no connection between the front compartment of the cab, the steering column and the HUD mounting bracket. During vehicle turning, the mounting bracket is easy to detach from the steering mechanism, which is not conducive to ensuring the overall vehicle steering mode and is prone to resonance with the engine.

[0005] In addition, existing technologies disclose HUD bracket structures in which the two sides of the HUD bracket are connected as one piece. However, these structures do not take into account the connection between the HUD bracket and the steering column, and therefore cannot effectively guarantee the vehicle's steering mode. Moreover, the HUD bracket is a flat structure that only provides simple support for the HUD from the bottom, resulting in poor stability of the head-up display device and making it easy for the HUD to collide with other components after installation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mounting structure for a vehicle head-up display device that can meet the installation accuracy requirements of the head-up display device and also achieve the effect of crumple zone energy absorption in the vehicle's steering mode.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A mounting structure for a vehicle head-up display (HUD) includes a mounting bracket, which is an integral structure. The mounting bracket has a support groove to support the HUD, and the support groove fits into the lower half of the HUD. The mounting bracket has multiple openings that communicate with the support groove to facilitate signal transmission. The mounting bracket has a connecting edge on the side of the support groove, which can contact the HUD to facilitate fastener connection between the connecting edge and the HUD. One side of the mounting bracket can be connected to the front compartment of the driver's cab, the other side of the mounting bracket can be connected to the main beam, and the bottom of the mounting bracket can be connected to the steering column.

[0009] As described above, the mounting structure for a vehicle head-up display device includes several through holes at the bottom of the mounting bracket to cooperate with the head-up display device. These through holes allow for energy absorption and crumple at the points where the mounting bracket will collapse during a vehicle collision. The through holes also optimize the mounting bracket, preventing stress concentration and fracture failure during a collision. This enhances the energy absorption effect of the mounting bracket, thus preventing stress transmission to the steering column and avoiding secondary injuries to the driver from the steering wheel.

[0010] As described above, the mounting structure for a vehicle head-up display device has two through holes at the bottom of the mounting bracket, with a distance between the two through holes, and the area of ​​one through hole is larger than the area of ​​the other through hole.

[0011] As described above, the mounting structure for a vehicle head-up display includes a first connecting edge and a second connecting edge. The first connecting edge is connected to the upper side of the main beam, and the second connecting edge is connected to the main beam at a position lower than the connection position of the first connecting edge to the main beam. The second connecting edge is bent and its middle part protrudes upward, so that both the first and second connecting edges can be effectively fitted to the head-up display, ensuring a stable connection between the mounting bracket and the head-up display.

[0012] As described above, in a vehicle head-up display mounting structure, the second connecting edge is provided with a waist-shaped hole. The waist-shaped hole is located near the main beam and above the vehicle air conditioning mounting hole. While optimizing the second connecting edge, the waist-shaped hole allows the operator to see the air conditioning mounting hole below. On the instrument panel assembly line, the operator can confirm whether there is a certain mounting point for fastening the air conditioning and whether the head-up display is completely attached to the mounting surface of the instrument panel beam.

[0013] As described above, the mounting structure for a vehicle head-up display device has a reinforcing rib on the side of the mounting bracket that connects to the front compartment of the driver's cab to improve structural strength. The side of the mounting bracket near the main beam is a sloping side, and the sloping side of the mounting bracket is connected to the bottom of the mounting bracket at an obtuse angle. One end of the sloping side is bent to be welded to the main beam.

[0014] As described above, in a mounting structure for a vehicle head-up display device, considering the bottom structure of the head-up display device, the bottom of the mounting bracket is connected to the side of the mounting bracket near the front compartment of the driver's cab at an obtuse angle. A column connecting bracket is welded to the bottom of the mounting bracket to connect with the steering column. A notch is provided in the middle of the inclined side of the mounting bracket, and the column connecting bracket is exposed from the notch.

[0015] As described above, a mounting structure for a vehicle head-up display device is provided, wherein the mounting bracket is used to provide a front compartment connecting bracket on one side connected to the front compartment of the driver's cab. The front compartment connecting bracket is provided in at least two places, and the front compartment connecting bracket includes a gantry frame with a threaded hole in the middle and support frames on both sides of the gantry frame. The two sides of the gantry frame and the support frames are respectively fixedly connected to the mounting bracket.

[0016] Secondly, the present invention also provides a vehicle instrument crossbeam component, including the aforementioned mounting structure for a vehicle head-up display device.

[0017] Thirdly, the present invention also provides a method for installing a mounting structure for a vehicle head-up display device, comprising the following:

[0018] The mounting bracket is manufactured as a single piece. During the manufacturing process, a support groove is formed on the mounting bracket, and multiple openings are punched into the mounting bracket.

[0019] Connect one side of the mounting bracket to the front compartment connecting bracket, and connect the other side of the mounting bracket to the main beam.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1) The present invention provides an installation structure in which the mounting bracket is provided with a support groove, which can support the head-up display device. The support groove fits with the lower half of the head-up display device, thus ensuring stable support of the head-up display device by the mounting bracket and avoiding collisions between the head-up display device and other components. In addition, the setting of the connecting edge can make the head-up display device and the mounting bracket reliably connected. The integrated mounting bracket ensures the installation accuracy of the head-up display device. The mounting bracket can be connected to the front compartment of the cab and the steering column, so that the mounting bracket is connected to the front compartment of the cab, the steering column and the main beam, and can be connected into a unified whole, which is beneficial to improving the steering mode of the whole vehicle.

[0022] 2) The bottom of the mounting bracket in this invention is provided with a through hole, which allows the HUD to be installed through the through hole. In addition, the through hole can optimize the structure of the mounting bracket. In the event of a vehicle collision, stress concentration will occur preferentially at the through hole, resulting in fracture failure. This improves the energy absorption effect of the mounting bracket by collapsing, thereby preventing stress from being transmitted to the steering column and avoiding secondary injury to the driver from the steering wheel at the steering column. This improves the safety performance of the vehicle. Like the through hole, it also serves as a shielding function for signal transmission, which is beneficial for heat dissipation and weight reduction.

[0023] 3) The mounting bracket structure in this invention is reasonably designed. The mounting bracket is designed with an inclined side and a notch on the inclined side. The pipe column connecting bracket can be exposed from the notch. The notch design also prioritizes stress concentration to cause fracture failure. The side bending of one side of the mounting bracket also optimizes the overall structure. Under the premise of meeting the modal requirements, it will preferentially collapse in the event of a collision to improve safety. Moreover, the inclined side bending design is welded to the main beam. In addition, the first connecting edge and the end of the second connecting edge are connected to the main beam, thus ensuring the connection strength between the mounting bracket and the main beam.

[0024] 4) In this invention, a front compartment connecting bracket is provided on one side of the mounting bracket for connection with the front compartment of the cab. The front compartment connecting bracket has a reasonable structure. A column connecting bracket is provided at the bottom of the mounting bracket to ensure smooth connection between the mounting bracket and the steering column. Attached Figure Description

[0035] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] As described in the background section, existing HUD mounting brackets have problems such as being unfavorable to the vehicle's steering mode and failing to provide stable support for the head-up display device. In order to solve the above technical problems, this invention proposes a mounting structure for a vehicle head-up display device.

[0038] Example 1

[0039] In a typical embodiment of the present invention, reference is made to Figure 2As shown, a mounting structure for a vehicle head-up display (HUD) includes a mounting bracket 7, which is an integral structure. The mounting bracket 7 is provided with a support groove 18 to support the HUD, thus making the overall mounting bracket a box-like structure. The support groove 18 fits against the lower half of the HUD. The mounting bracket 7 is provided with multiple openings 11, which communicate with the support groove 18 to facilitate signal transmission. The mounting bracket 7 has a connecting edge on the side of the support groove 18, which can contact the HUD to facilitate fastener connection between the connecting edge and the HUD. One side of the mounting bracket 7 can be connected to the front compartment of the driver's cab, and the other side of the mounting bracket can be connected to the main beam 9 in the instrument crossbeam. The bottom of the mounting bracket 7 can be connected to the steering column.

[0040] refer to Figure 3 and Figure 5 As shown, considering the bottom structure of the head-up display device, the mounting bracket 7 includes a bottom, and the side of the mounting bracket 7 near the main beam is an inclined side. The mounting bracket also includes a side wall, which connects the inclined side and the connection side of the mounting bracket with the front compartment of the cab. The opening 11 is provided at the bottom, inclined side, side wall and connection side of the mounting bracket with the front compartment of the cab. The opening facilitates the signal transmission shielding function when the head-up display device is working, which is beneficial for heat dissipation and weight reduction.

[0041] It is easy to understand that the inclined side of the mounting bracket 7 is connected to the bottom of the mounting bracket 7 at an obtuse angle. One end of the inclined side is bent upward to be welded to the main beam 9. The bottom of the mounting bracket is also connected to the side of the mounting bracket near the front of the cab at an obtuse angle. A column connecting bracket 10 is welded to the bottom of the mounting bracket 7 to be connected to the steering column. A notch 19 is provided in the middle of the inclined side of the mounting bracket. The length of the notch 19 is less than the length of the inclined side. The notch has a set width, and the column connecting bracket is exposed from the notch. The width of the notch is less than the width of the column connecting bracket. The setting of the notch also prioritizes stress concentration to cause fracture failure, thereby improving safety.

[0042] Specifically, the column connecting bracket 10 includes a connecting base plate, the width of which is greater than the width of the notch. The connecting base plate is welded to the bottom of the mounting bracket. A connecting hole is provided at the connecting base plate, which can be exposed from the notch on the inclined side of the mounting bracket. Two connecting lugs are provided on the side of the connecting base plate away from the main beam, and the connection with the steering column is achieved through the two connecting lugs.

[0043] refer to Figure 5As shown, the mounting bracket 7 is used to connect to the front compartment of the cab. There are two front compartment connecting brackets 8, and the two front compartment connecting brackets 8 are spaced apart. The front compartment connecting bracket 8 includes a gantry frame 20. The gantry frame 20 has a threaded hole in the middle. Support frames 21 are respectively provided on both sides of the gantry frame 20. The two sides of the gantry frame 20 and the support frames are welded to the mounting bracket 7.

[0044] In some examples, the two sides of the portal frame 20 and the support frame can be flat plates or inclined plates, and the bottom side of the portal frame and the bottom side of the support frame 21 can be bent to increase the contact area with the mounting bracket and ensure the connection strength.

[0045] It should be noted that, considering the protruding block on the bottom side of the HUD, several through holes are provided at the bottom of the mounting bracket 7. The protruding block of the HUD passes through the through holes. In addition, when a vehicle collision occurs, the through holes of the mounting bracket will collapse and absorb energy. The through holes also serve to optimize the mounting bracket. When a vehicle collision occurs, stress concentration will occur preferentially at the through holes, resulting in fracture failure. This improves the energy absorption effect of the mounting bracket's collapse, thereby preventing stress from being transmitted to the steering column and avoiding secondary injury to the driver from the steering wheel at the steering column.

[0046] In this embodiment, reference Figure 4 As shown, the bottom of the mounting bracket 7 is provided with two through holes, which also serve to dissipate heat. The two through holes are spaced apart. The area of ​​the first through hole 15, which is the through hole near the waist-shaped hole, is larger than the area of ​​the second through hole 14. The two through holes are located on both sides of the column connecting bracket.

[0047] In other examples, the bottom of the mounting bracket 7 is provided with two through holes, with a distance between the two through holes, and the area of ​​one through hole is larger than the area of ​​the other through hole.

[0048] Understandably, the mounting bracket 7 is provided with a reinforcing rib 17 on the side connected to the front compartment of the cab to improve structural strength. There may be two reinforcing ribs 17, with a distance between them. The reinforcing rib 17 may be a reinforcing plate. The reinforcing rib 17 may be integrally formed with the mounting bracket, or the reinforcing rib may be welded to the outside of the mounting bracket later.

[0049] In this embodiment, reference Figure 5As shown, the connecting edge of the mounting bracket 7 is connected to the side wall. The connecting edge is formed by folding the top of the side wall. The connecting edge includes a first connecting edge 12 and a second connecting edge 13. The first connecting edge 12 is a flat plate. The first connecting edge 12 is bent downwards towards the main beam and welded to the upper side of the main beam. The second connecting edge 13 is connected to the main beam at a position lower than the connection position of the first connecting edge to the main beam. The second connecting edge 13 is bent and its middle part protrudes upwards. This allows both the first connecting edge 12 and the second connecting edge 13 to effectively fit with the head-up display device, ensuring a stable connection between the mounting bracket and the head-up display device. Moreover, the bent second connecting edge 13 is optimized to facilitate priority crumpling in the event of a vehicle collision, ensuring vehicle safety.

[0050] In addition, the second connecting edge 13 is provided with a waist-shaped hole 16. The waist-shaped hole 16 is located close to the main beam 9 and is located above the vehicle air conditioning mounting hole. While optimizing the second connecting edge, the waist-shaped hole allows the staff to see the air conditioning mounting hole below. On the instrument assembly line, the staff can confirm whether there is a certain mounting point for the air conditioning that is fastened and whether the head-up display device is completely attached to the mounting surface of the instrument beam.

[0051] The integrated mounting bracket provided in this embodiment ensures the installation accuracy of the head-up display device. The mounting bracket can be connected to the front compartment of the cab and the steering column, allowing for connections between the mounting bracket and the front compartment of the cab, the steering column, and the main beam, forming a unified whole. This improves the overall vehicle's steering modality. (Refer to...) Figure 6 and Figure 7 As shown, through existing software simulation analysis, using the installation structure provided in this embodiment, the vehicle's vertical steering mode is 42.5 Hz and the horizontal steering mode is 40 Hz, which is higher than the standard requirement of 35 Hz. In addition, the mounting bracket is provided with a support groove, which can support the head-up display device. The support groove fits in close contact with the lower half of the head-up display device, thus ensuring the stable support of the mounting bracket for the head-up display device and avoiding collisions between the head-up display device and other components.

[0052] Example 2

[0053] This embodiment also provides a vehicle instrument crossbeam component, including the mounting structure for a vehicle head-up display device described in Embodiment 1, wherein the mounting bracket is welded to the main beam in the vehicle instrument crossbeam, so that the mounting bracket, the front compartment of the driver's cab, the steering column and the main beam form an integral whole.

[0055] This embodiment also provides an installation method for a mounting structure of a vehicle head-up display device, including the following:

[0056] The mounting bracket is manufactured by integral molding, making it an integrated component. During the manufacturing process, a support groove is formed, and multiple openings are punched into the mounting bracket.

[0057] A front compartment connecting bracket is welded to one side of the mounting bracket, and a column connecting bracket is set at the bottom of the mounting bracket. The inclined side, the first connecting edge, and the second connecting edge of the mounting bracket are all welded to the main beam.
