[0036] In addition, the terms "first", "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0037] The head-up display device 100 (Head Up Display, HUD) can project important driving information such as speed, navigation, etc. onto the windshield in front of the driver, so that the driver can view the driving information without lowering or turning his head.

[0038] The head-up display device 100 generally includes a combined head-up display system (C-HUD), a windshield head-up display system (W-HUD), and an augmented reality head-up display system (AR-HUD). The head-up display device 100 is gradually increasing in popularity, and the augmented reality head-up display system is becoming a new development direction.

[0039] The head-up display device 100 is generally connected and fixed to the instrument panel cross beam 300 (Car Cross Beam, CCB) through a head-up display support. With the development of the head-up display device 100, the function is becoming more and more powerful, and the size and weight are gradually increasing, so a more solid support is needed. In addition, in order to meet the modal target of the steering wheel, the support stiffness of the head-up display support is large. Then, in the case of a frontal collision of the vehicle 1, the support stiffness of the head-up display support is large and is not easy to deform, which will invade other spaces, for example, into the position of the instrument panel cross beam 300. If the invasion amount is too large, it is easy to cause the instrument panel cross beam 300 to break, which may cause potential harm to the driver and passengers.

[0040] Therefore, the design and manufacture of the head-up display support not only needs to consider the support stiffness to reduce the probability of breaking the instrument panel cross beam 300, but also needs to consider the modal target of the steering wheel.

[0041] To at least solve the above technical problems, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The embodiments of the present application provide a vehicle 1, which can be a pure electric vehicle, a hybrid vehicle, a fuel vehicle or other power vehicle 1.

[0042] Please refer to Figure 2 The vehicle 1 provided by the embodiments of the present application includes two A-pillars 400 which are spaced apart along a first direction (such as the X direction in Figure 2 The vehicle 1 further includes a front apron 200 and an instrument panel cross beam 300, which are spaced apart along a second direction (such as the Y direction in Figure 2The front wall 200 and the instrument panel beam 300 have a gap in the second direction (Y direction in the figure). The two ends of the front wall 200 in the first direction are connected with two A-pillars 400 respectively, and the two ends of the instrument panel beam 300 in the first direction are connected with the two A-pillars 400 respectively. The front wall 200, the instrument panel beam 300 and the two A-pillars 400 are connected and define a buffer area. The buffer area can accommodate the deformation amount of the front wall 200 when the vehicle 1 is deformed in a collision. It can be understood that the first direction can be the width direction of the vehicle 1, and the second direction can be the length direction of the vehicle 1.

[0043] Please refer to Figure 2 、 Figure 3 and Figure 4 The vehicle 1 further comprises a head-up display device 100, the head-up display device 100 comprising a head-up display bracket, a cover plate and a head-up display component (not shown in the figure). The cover plate is connected with the head-up display bracket and encloses a receiving cavity, and the head-up display component is arranged in the receiving cavity. The head-up display bracket is installed in the gap between the front wall 200 and the instrument panel beam 300 and is located in the buffer area.

[0044] The head-up display bracket comprises a bracket body 10 and a plurality of support pieces 20. The bracket body 10 comprises at least one mounting portion 11 for connecting the front wall 200. The plurality of support pieces 20 are arranged at intervals in the height direction (Z direction in the figure) of the vehicle 1. One end of the support piece 20 is connected with the bracket body 10, and the other end is used for connecting the instrument panel beam 300. The support piece 20 comprises at least one collapse portion. Figure 4

[0045] It can be understood that in the case of a frontal collision of the vehicle 1, if the intrusion amount is too large, the support piece 20 can be deformed at the collapse portion to provide a buffering effect, absorb the energy generated by the collision, reduce the energy transmitted to the instrument panel beam 300, and avoid breaking the instrument panel beam 300. In addition, the instrument panel beam 300 can protect the steering wheel, and can reduce the intrusion amount towards the steering wheel (not shown in the figure), which is beneficial to avoid potential harm to the driver and passenger.

[0046] In addition, the plurality of support pieces 20 are arranged at intervals in the height direction of the vehicle 1, which can support the head-up display bracket at multiple positions. The support piece 20 is also used for connecting the instrument panel beam 300. The plurality of support pieces 20 connecting the instrument panel beam 300 can improve the stability of the instrument panel beam 300, which is beneficial to reduce the vibration of the instrument panel beam 300. It can be understood that the steering wheel is installed on the instrument panel beam 300, and the plurality of support pieces connecting the instrument panel beam 300 can improve the stability of the steering wheel and also be beneficial to reduce the vibration of the steering wheel, thereby being beneficial to meet the modal target of the steering wheel.

[0047] ​Therefore, the HMD support provided by the application can solve the problem of easy breakage of the instrument panel beam 300 and facilitate meeting the modal target of the steering wheel.

[0048] Optionally, the plurality of support members 20 can include a first support member 21, a second support member 22, and a third support member 23.

[0049] Optionally, the first support member 21, the second support member 22, and the third support member 23 are sequentially and spacedly arranged in a direction from the top of the vehicle 1 to the chassis of the vehicle 1.

[0050] Please refer to Figure 5 and Figure 6 In some embodiments, the plurality of support members 20 at least includes the first support member 21, which is one of the plurality of support members 20 arranged close to the top of the vehicle 1. The collapse portion of the first support member 21 includes a collapse hole 211, and the axial direction of the collapse hole 211 is perpendicular to the length direction of the first support member 21 (such as the Y direction in Figure 5 In this way, the first support member 21 can collapse when the HMD support is impacted, avoiding intrusion into the area where the instrument panel support is located.

[0051] Optionally, the axial direction of the collapse hole 211 can be the Y direction. Optionally, the axial direction of the collapse hole 211 can be the Z direction.

[0052] Optionally, the collapse hole 211 can be a circular hole, an elliptical hole, or the like.

[0053] Exemplarily, the collapse hole 211 is an elliptical hole, and the long axis direction of the collapse hole 211 is the first direction, which facilitates the deformation of the first support member 21 at the collapse hole 211.

At this time, the axial direction of the collapse hole 211 can be the Z direction.

[0055] In this way, the side walls of the collapse portion have a tendency to collapse, which facilitates the deformation of the first support member 21 at the collapse portion.

[0056] Please refer to Figure 7 In some embodiments, the first support member 21 further includes at least one collapse rib 212, and the collapse rib 212 passes through the collapse hole 211 in the length direction of the first support member 21. It can be understood that the collapse rib 212 can increase the strength of the collapse portion of the first support member 21, which facilitates making up for the modal loss caused by the collapse hole 211.

[0057] Optionally, the collapse rib 212 protrudes in a direction away from the center of the collapse hole 211. In this way, the collapse rib 212 can generate a collapse deformation together with the collapse portion.

[0059] Optionally, the collapse rib 212 is two and is distributed on both sides of the center of the collapse hole 211 in the first direction.

[0060] Please refer to Figure 8 In some embodiments, the first support 21 comprises a guide rib 213 connected with the collapse rib 212 and located at least on one side of the collapse rib 212 close to the support body 10. It can be understood that the guide rib 213 can transmit the impact on the support body 10 to the collapse rib 212, so that the collapse rib 212 can generate a collapse deformation or even breakage.

[0061] Optionally, the guide rib 213 can also be located on one side of the collapse rib 212 close to the instrument panel beam 300. The guide ribs 213 on both sides of the collapse rib 212 in the length direction of the first support 21 can simultaneously press the collapse rib 212, so that the collapse rib 212 is more likely to generate a collapse deformation or even breakage.

[0062] Optionally, the first support 21 is two and is arranged in the first direction. Optionally, the head-up display support provided by the embodiments of the present application further comprises a connecting rod 30, which can be connected with the two first supports 21.

[0068] In this way, when the head-up display support is impacted, the second support 22 can generate a collapse deformation at the first connecting point 2201 and / or the second connecting point 2202.

[0069] Please continue to refer to Figure 5 In some embodiments, the plurality of supports 20 includes a third support 23, which is one of the plurality of supports 20 arranged close to the chassis of the vehicle 1.

[0070] Optionally, the third support 23 is provided with at least one bending part 231, and the bending part 231 forms a collapse part of the third support 23. It can be understood that when the head-up display support is impacted, the third support 23 can generate a collapse deformation at the bending part 231.

[0071] Optionally, the bending part 231 can be bent in a first direction (a width direction of the vehicle 1). Optionally, the bending part 231 can be bent in a height direction of the vehicle 1.

[0072] For example, the bending part 231 can be bent in a direction towards the top of the vehicle 1. For example, the bending part 231 can be bent in a direction towards the chassis of the vehicle 1.

[0073] Please continue to refer to Figure 6 In some embodiments, the support body is provided with a recess 101 for accommodating at least part of the head-up display device 100.

[0074] It can be understood that the cover plate of the head-up display device 100 can be arranged at the opening of the recess 101, and the cover plate can be enclosed with the recess 101 to form an accommodation cavity for accommodating the head-up display device.

[0075] It should be noted that the vehicle 1 provided by the embodiments of the present application can cause the head-up display support to collapse and deform during the collision process, thereby avoiding the rupture of the instrument panel support and avoiding the intrusion into the vehicle cabin, thereby improving the safety performance in the vehicle cabin.
