[0026] The present application provides a mounting bracket, a radar assembly and a vehicle. The mounting bracket, the radar assembly and the vehicle are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0027] The mounting bracket provided in the present application can be used to install radar equipment, sensor equipment, etc. However, in order to facilitate the description of the present solution, the following embodiments are all described in detail by taking radar equipment as an example.

[0028] refer to Figures 1 to 4The embodiment of the present application provides a radar assembly, including a radar device 40 and a mounting bracket, wherein the radar device 40 includes a radar mounting ear 41, and the mounting bracket includes a bracket body 10 and a snap-on spring piece 20, wherein the bracket body 10 includes a receiving cavity 11, wherein the receiving cavity 11 has a mounting opening 12, and wherein a limiting groove 13 communicating with the mounting opening 12 is formed in the receiving cavity 11; the snap-on spring piece 20 includes a fixing portion 22 connected to the bracket body 10 and a movable limiting portion 21, wherein the limiting portion 21 is located at the mounting opening 12. 2, and is arranged opposite to the limiting groove 13; wherein, the clamping spring piece 20 has a limiting state and a disassembly state. In the limiting state, the limiting groove 13 is used to limit the radar mounting ear 41, and the limiting portion 21 is used to press the end of the radar mounting ear 41 away from the limiting groove 13, and lock the radar mounting ear 41 in the limiting groove 13; that is, in the limiting state, one end of the radar mounting ear 41 presses against the limiting portion 21 of the clamping spring piece 20, and the other end is arranged in the limiting groove 13. In the disassembly state, the limiting portion 21 can move in a direction close to or away from the accommodating cavity 11, and is used to unlock the radar mounting ear 41. At this time, the radar mounting ear 41 can be pushed into the limiting groove 13 or taken out from the limiting groove 13.

[0029] It should be noted that the limiting portion 21 can be moved in a direction close to or away from the accommodating cavity 11. Specifically, the limiting portion 21 can be pressed into the accommodating cavity 11; or the limiting portion 21 can be pulled out of the accommodating cavity 11. However, it is not limited to this. In addition, the limiting groove 13 and the limiting portion 21 can also be used to limit other electronic devices, such as infrared sensors, etc., but it is not limited to this.

[0030] According to the above description, in the limited state, the clamping spring 20 presses against the end of the radar mounting ear 41 away from the limiting groove 13, and fixes the radar mounting ear 41 of the radar device 40 in the limiting groove 13, forming a locked state. In this way, on the one hand, the radar device 40 will not shake or move due to inaccurate position, and on the other hand, even under certain vibration or impact force in the external environment, the radar device 40 is not easy to be separated from the limiting groove 13. Therefore, this solution can improve the assembly stability of the radar device 40 and improve the reliability of the radar device 40. In addition, when disassembling the radar device 40, it is only necessary to press the limiting spring into the accommodating cavity 11 (or pull it out of the accommodating cavity) to unlock the limiting spring and the radar mounting ear 41, and the operator can remove the radar mounting ear 41 from the limiting groove 13 to complete the disassembly of the radar device 40. Similarly, when installing the radar device 40, first press the limiting spring piece into the accommodating cavity 11 (or pull it out of the accommodating cavity), and then push the radar mounting ear 41 into the limiting groove 13. At this time, the limiting spring piece can rebound from the accommodating cavity 11 and press the end of the radar mounting ear 41 away from the limiting groove 13 to complete the installation. Therefore, this solution also facilitates the rapid disassembly and assembly of the radar device 40.

[0031] In one embodiment, the radar device 40 may be a millimeter wave radar, a laser radar, an ultrasonic radar, etc., but is not limited thereto.

[0032] In one embodiment, the mounting bracket includes a connecting portion 15 connected to the bracket body 10. The connecting portion 15 protrudes outward from the bracket body 10. The connecting portion 15 may be provided with a connecting hole that passes through the thickness direction thereof. The connecting hole allows a threaded connector to pass through, so as to fix the entire mounting bracket to a designated position of the vehicle. The number of connecting portions 15 may be set as required. Figure 1 In the illustrated embodiment, three connecting portions 15 are provided, but the present invention is not limited thereto.

[0033] In one embodiment, the radar device 40 may include a plurality of radar mounting ears 41, and correspondingly, the mounting bracket may include a plurality of limiting grooves 13 as described above, and the plurality of radar mounting ears 41 correspond to the plurality of limiting grooves 13 one by one, and the corresponding radar mounting ears 41 are arranged in the limiting grooves 13. Further, the number of the snap-fit ​​spring pieces 20 may not correspond to the number of the limiting grooves 13, that is, the number of the snap-fit ​​spring pieces 20 may be at least one, and one snap-fit ​​spring piece 20 corresponds to one of the plurality of limiting grooves 13.

[0034] like Figure 1 In the illustrated embodiment, the mounting bracket includes three limiting slots 13 and two snap-on springs 20. The three limiting slots 13 are distributed at three vertices of a triangle. One of the two snap-on springs 20 corresponds to the limiting slot 13 located at the upper portion, and the other corresponds to the limiting slot 13 located at the lower right portion. Of course, in other embodiments, the mounting bracket may include other numbers of limiting slots 13 and other numbers of snap-on springs 20, but it should be noted that the number of snap-on springs 20 is generally less than or equal to the number of limiting slots 13.

[0035] It should be noted that, in order to facilitate the description of the present application, the following embodiments are described with one limiting groove 13 and one clamping elasticity.

[0036] refer to Figure 5 and Figure 6 Combined with Figure 3 and Figure 4 In one embodiment, the limiting groove 13 includes a limiting inner surface 131, and the limiting inner surface 131 is a semi-enclosed structure. When in the limiting state, the limiting inner surface 131 is used to cover the end of the radar mounting ear 41. The limiting inner surface 131 is a semi-enclosed structure, which can better cover the end of the radar mounting ear 41 and form a tighter fixation in the limiting state. In this way, even if there is a certain vibration or impact in the external environment, the radar mounting ear 41 is not easy to separate from the limiting groove 13, thereby ensuring the stable installation of the radar device 40.

[0037] In a further embodiment, the limiting inner surface 131 includes a top limiting surface 1311, which is located at the installation opening 12 and is used to limit the radar mounting ear 41 at the installation opening 12. By providing the top limiting surface 1311 at the installation opening 12, the radar mounting ear 41 can be prevented from detaching from the installation opening 12, thereby ensuring the stability and reliability of the installation of the radar device 40.

[0038] refer to Figure 6 Combined with Figure 4 In one embodiment, the limiting inner surface 131 is configured to match the shape of the radar mounting ear 41. When in the limiting state, the limiting inner surface 131 is completely fitted with the end of the radar mounting ear 41. In this way, the end of the radar mounting ear 41 is completely fitted with the limiting inner surface 131, which can increase the limiting matching area between the radar mounting ear 41 and the limiting groove 13, and reduce the gap between the radar mounting ear 41 and the limiting inner surface 131, thereby avoiding the shaking or loosening of the radar mounting ear 41 as much as possible, and improving the installation stability of the radar device 40.

[0039] Continue to refer Figure 5 and Figure 6 In one embodiment, the mounting bracket further includes a guide structure 30 connected to the bracket body 10, the guide structure 30 is located above the limiting groove 13, and the guide structure 30 includes a guide surface 31 connected to the limiting groove 13, and the guide surface 31 extends obliquely upward from the limiting groove 13 to the clamping spring piece 20. In the process of pushing the radar mounting ear 41 into the limiting groove 13, the guide surface 31 can play a guiding role, so that the radar mounting ear 41 can enter the limiting groove 13 more smoothly.

[0040] In a further embodiment, the guide structure 30 further includes a transition surface 32, the transition surface 32 connects the guide surface 31 and the limit groove 13, and the transition surface 32 is set as an arc surface. After such a configuration, when the radar mounting ear 41 slides from the guide surface 31 into the limit groove 13, the friction and resistance of the radar mounting ear 41 in this process can be reduced, thereby preventing possible wear during installation and making the entire installation process smoother and more stable.

[0041] In one embodiment, the guide structure 30 may be integrally formed with the bracket body 10 , but is not limited thereto.

[0042] refer to Figure 6 Combined with Figure 4In one embodiment, the accommodating cavity 11 further includes a groove 14 directly opposite to the limiting portion 21, the groove 14 is recessed toward a side away from the limiting portion 21, and the height of the lowest point of the groove 14 is lower than the height of the lowest point of the limiting groove 13. In the disassembly state, the limiting portion can be pressed into the accommodating cavity and pressed into the groove 14. The groove 14 is a accommodating space provided by the limiting portion 21. In the disassembly state, the limiting portion 21 can be pressed into the groove 14 lower than the limiting groove 13. The limiting portion 21 located in the groove 14 can avoid obstruction to the removal of the radar mounting ear 41 in the limiting groove 13 as much as possible, and the radar mounting ear 41 can be more conveniently taken out of the limiting groove 13.

[0043] Furthermore, the depth of the groove 14 is equal to the thickness of the limiting portion 21. When the limiting portion 21 is pressed into the groove 14, the top wall of the limiting portion 21 is flush with the bottom wall of the limiting groove 13, so that the limiting portion 21 located in the groove 14 has no interference with the radar mounting ear 41 in the limiting groove 13, and the radar mounting ear 41 can be smoothly taken out of the limiting groove 13. Similarly, in this state, the radar mounting ear 41 can also smoothly enter the limiting groove 13.

[0044] In one embodiment, the ratio of the thickness to the width of the snap-on shrapnel 20 is set to 1:5, that is, the width of the snap-on shrapnel 20 is 5 times its thickness, and the ratio of the thickness to the length of the snap-on shrapnel 20 is 1:8.75, that is, the length of the snap-on shrapnel 20 is 8.75 times its thickness. Such a setting can make the snap-on shrapnel 20 have better elasticity, so that the snap-on shrapnel 20 can be more conveniently pressed into the accommodating cavity 11, and rebound from the accommodating cavity 11 to abut against the radar mounting ear 41. In some exemplary embodiments, the thickness of the snap-on shrapnel 20 can be 1.6mm, then its width is 8mm and its length is 14mm. Alternatively, the thickness of the snap-on shrapnel 20 can be 1.5mm, and its width is 7.5mm. Its length is 13.125mm. However, it is not limited to this. It should be noted that the above-mentioned ratio restrictions are only preferred embodiments and are not used to limit the present application. In addition, in industrial manufacturing, there may be some errors in the proportions of the snap-on spring 20. For example, the ratio of the thickness to the width of the snap-on spring 20 may be between 1:4 and 1:6, and the ratio of the thickness to the length of the snap-on spring 20 may be between 1:7 and 1:9, which should also be considered within the scope of protection of this application.

[0045] The thickness direction and the depth direction of the groove 14 are: Figure 6 The top and bottom directions are shown, and the length direction is Figure 6 The left and right directions shown, the width direction is Figure 6 The direction perpendicular to the paper surface (i.e. Figure 1 up and down directions as shown).

[0046] The embodiment of the present application also provides a vehicle (not shown), comprising a radar assembly or a mounting bracket as shown in any of the above embodiments. The radar assembly can be set at any position of the vehicle, for example, the radar assembly can be set inside the front bumper or front grille of the vehicle, can also be set on the side of the vehicle body or around the side mirror, can also be set inside the rear bumper of the vehicle, but are not limited thereto.

[0047] The vehicle may be a car, truck, van, sport utility vehicle, or any other type of vehicle with a battery. In one embodiment, the vehicle is a high voltage traction battery powered electric vehicle (e.g., a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), etc.). In another embodiment, the vehicle is an autonomous vehicle that controls the maneuvering functions of the vehicle without direct input from a human driver.
