Description

Technical Field

[0001] The utility model relates to the technical field of automobile radar installation, in particular to a front radar bracket installed on a front crossbeam column of a vehicle frame. Background Art

[0002] At present, new energy heavy-duty trucks must meet the forward AEB regulatory requirements and must be equipped with a forward millimeter-wave radar.

[0003] In the prior art, forward millimeter-wave radars are mostly installed and fixed on the front lower guard or front crossbeam of the vehicle, with the disadvantages of low installation height and easy collision damage. At the same time, the frequency of disassembly of the front lower guard is high, and the forward millimeter-wave radar needs to be calibrated repeatedly when its position is changed. When installed at the front lower guard position or on the front crossbeam, the positioning deviation of the forward millimeter-wave radar is large, and there are also disadvantages such as difficulty in wiring harness connection. The wiring harness difficulty specifically refers to that if the front radar bracket is installed at the front lower guard position, then due to the connection between the front lower guard position and the front bumper, the front radar bracket can only be installed first and then the front bumper, which will reduce the installation efficiency of new energy heavy trucks when producing new energy heavy trucks. Utility Model Content

[0004] In order to achieve the purpose of reducing the positioning deviation of a forward millimeter-wave radar while preventing collision damage, a front radar bracket installed on a front crossbeam column of a vehicle frame is provided.

[0005] The following technical solution is adopted: a front radar bracket installed on the front cross beam column of the frame, the front cross beam column of the frame is installed on the front cross beam of the frame, and the volume of the front radar bracket is less than 2dm 3 , and is not higher than the front crossbeam of the frame, including: a base bracket, fixedly installed on the front crossbeam pipe column of the frame; an adapter bracket, fixedly installed on the base bracket; a mounting bracket, one end of which is fixedly installed on the adapter bracket, and the other end is used to fix the forward millimeter-wave radar.

[0006] Beneficial effects: Compared with the prior art, this solution is completely different. First, this solution installs the front radar bracket on the front crossbeam column of the frame. In the event of a vehicle collision, the front crossbeam column of the frame is relatively high and difficult to collide with. Moreover, the forward millimeter-wave radar is not easy to move when installed on the front crossbeam column of the frame. The positioning deviation of the forward millimeter-wave radar is small, which satisfies the accurate detection of the forward radar. At the same time, the height of the front radar bracket is not higher than the front crossbeam of the frame and the volume is small. Even if the collision height reaches the height of the front crossbeam of the frame, the front radar bracket will be located in the space formed by the front and rear front crossbeams of the frame. When the front crossbeam of the frame is not seriously damaged, the front radar bracket will not be damaged.

[0007] Subsequently, by changing the size of the adapter bracket, it can be used to adjust the position of the mounting bracket, so as to flexibly change the position of the forward millimeter-wave radar.

[0008] Finally, in this solution, the front radar bracket is installed on the front crossbeam column of the vehicle frame, and it has no connection with the front bumper or the front underguard beam of the vehicle. When the prior art installs on the front underguard beam and uses a wire harness to connect to the front radar bracket, it is necessary to connect the wire harness first and then install the front bumper. However, this solution can achieve the purpose of improving the production efficiency of vehicle installation without considering the sequence of installing the front radar bracket, the front underguard, and the front bumper.

[0009] Preferably, the base bracket is provided with an engaging arc surface that matches the outer surface shape of the front crossbeam column of the vehicle frame, and the engaging arc surface is used to tightly press against the outer surface of the front crossbeam column of the vehicle frame.

[0010] Beneficial effect: Since the shape of the outer surface of the column is circular, by matching with this circular shape, the structural stability can be improved.

[0011] Preferably, it further includes nuts and bolts; the adapter bracket is provided with a first support surface, and the base bracket is provided with a second support surface; the adapter bracket is fixedly installed on the base bracket through bolts; on the first support surface of the adapter bracket close to the base bracket, a first bolt hole is opened; and on the second support surface of the base bracket close to the adapter bracket, a second bolt hole that matches the first bolt hole is opened; nuts are welded on both the first bolt hole and the second bolt hole, and the nuts match the threads of the first bolt hole and the second bolt hole; the first bolt hole and the second bolt hole are connected by bolts.

[0012] Beneficial effect: In this way, it can withstand greater external forces, reduce loosening caused by vibration or impact, and improve the stability and operation reliability of the entire structure. The design of welding nuts strengthens the strength of the area around the bolt holes, prevents the deformation or damage of the hole positions during repeated disassembly and assembly or under external forces, and extends the service life of the entire device.

[0013] Preferably, a first weight-reducing hole is opened on the first support surface, and a second weight-reducing hole that matches the first weight-reducing hole is opened on the second support surface.

[0014] Beneficial effect: Both the first weight-reducing hole and the second weight-reducing hole can reduce the weight of the front radar bracket.

[0015] Preferably, both the adapter bracket and the mounting bracket are in a "U" shape, and the mounting bracket is fixedly installed on the adapter bracket through bolts; a third bolt hole is opened on the side of the adapter bracket, and a fourth bolt hole that matches the third bolt hole is opened on the side of the mounting bracket; nuts are welded on both the third bolt hole and the fourth bolt hole, and the nuts match the threads of the third bolt hole and the fourth bolt hole; the third bolt hole and the fourth bolt hole are connected by bolts.

[0016] Beneficial effects: The adapter bracket and the mounting bracket are both in a "U" shape, which can reduce the weight. And nuts are installed on the two brackets, which can bear greater external forces, reduce loosening caused by vibration or impact, and improve the stability and operation reliability of the entire structure. The design of the welded nut strengthens the strength of the area around the bolt hole, prevents the hole position from deforming or being damaged during repeated disassembly and assembly or under the action of external forces, and extends the service life of the entire device.

[0017] Preferably, a third support surface is provided on the mounting bracket, and a fifth bolt hole is opened on the third support surface of the mounting bracket for fixedly connecting the forward millimeter-wave radar through a bolt.

[0018] Beneficial effects: By fixedly connecting the forward millimeter-wave radar through a bolt, the stability of the millimeter-wave radar installed on the mounting bracket can be increased.

[0019] Preferably, a third weight-reducing hole is opened on the third support surface.

[0020] Beneficial effects: The third weight-reducing hole can reduce the overall weight of the front radar bracket.

[0021] Preferably, the bolt is an M6 bolt.

[0022] Beneficial effects: The M6 bolt is one of the internationally common standard specifications, with high wide applicability, and is convenient for procurement and replacement. The M6 bolt is suitable for a variety of medium and light load connection requirements, and there is no need to use bolts with higher specifications. Under the condition of reducing the bolt weight, it can also achieve the stability when installing the base bracket, adapter bracket and mounting bracket.

[0023] Preferably, the base bracket is located at the center of the front crossbeam column of the vehicle frame.

[0024] Beneficial effects: This is convenient for accurately positioning the forward millimeter-wave radar and the calibration is simple.

[0025] Preferably, the base bracket is welded at the middle position of the front crossbeam column of the vehicle frame.

[0026] Beneficial effects: By adopting the welding method, the base bracket and the front crossbeam column of the vehicle frame are firmly connected together. This enhances the stability of the structure and can avoid the problem of inaccurate positioning caused by the position deviation of the forward millimeter-wave radar.

[0027] The beneficial effects of the present utility model

[0028] Compared with the prior art, the structure of this solution is completely different. First, this solution installs the front radar bracket on the front crossbeam column of the frame. In the event of a vehicle collision, the front crossbeam column of the frame is relatively high and difficult to collide with. Moreover, the forward millimeter-wave radar is not easy to move when installed on the front crossbeam column of the frame. The positioning deviation of the forward millimeter-wave radar is small, which satisfies the accurate detection of the forward radar. At the same time, the height of the front radar bracket is not higher than the front crossbeam of the frame and the volume is small. Even if the height of the collision reaches the height of the front crossbeam of the frame, the front radar bracket will be located in the space formed by the front and rear front crossbeams of the frame. When the front crossbeam of the frame is not seriously damaged, the front radar bracket will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS
