[0002] This application claims priority to Korean Patent Application No. 10-2022-0001696, filed on January 5, 2022, which is incorporated herein by reference for all purposes, as fully set forth herein. Technical Field

[0003] This embodiment relates to a radar device mounting bracket assembly, and more specifically, to a radar device mounting bracket assembly that can achieve cost savings and simplify the assembly process by reducing the number of parts, improve quality by reducing tolerances during assembly, and achieve better stability and accuracy during angle adjustment. Background Technology

[0004] The vehicle is equipped with an electronic control unit (ECU) for electronically controlling various devices and receiving and processing information from sensors or switches installed thereon to perform control functions, thereby improving stability and steering feel.

[0005] Specifically, the vehicle has a radar system to identify surrounding objects, collect information such as distance to the vehicle, relative speed, or direction, and process this information so that the electronic control unit can perform collision avoidance or accident prevention functions by identifying the distance between the vehicle and surrounding objects. The radar system needs to be installed in the correct location to accurately identify the distance to surrounding objects.

[0006] However, errors are unavoidable during the manufacturing, assembly, or installation of radar devices onto vehicles. The traditional method to address these errors is to correct the radar device's orientation by adjusting its angle after mounting it on the bracket.

[0007] However, traditionally, too many components are used to adjust the angle of the radar device, leading to increased costs and assembly complexity. Furthermore, errors accumulate during assembly, causing excessive friction during angle adjustment, reducing the adjustment range, and resulting in a high defect rate. Summary of the Invention

[0008] This embodiment is conceived in the aforementioned context and relates to a radar device mounting bracket assembly that can achieve cost savings and simplify the assembly process by reducing the number of parts, improve quality by reducing tolerances during assembly, and achieve better stability and accuracy during angle adjustment.

[0009] According to this embodiment, a radar device mounting bracket assembly can be provided, the radar device mounting bracket assembly including: a first bracket, fixed to a vehicle body, and including a first connecting portion and a second connecting portion connected to the radar device and disposed on the front surface of the first bracket; a second bracket, including a third connecting portion connected to the radar device and movably connected to the first bracket in a forward or backward manner relative to the first bracket; and an adjusting member connected to the first bracket and the second bracket to move the second bracket relative to the first bracket.

[0010] According to this embodiment, cost savings and simplified assembly processes can be achieved by reducing the number of parts, and quality can be improved by reducing tolerances during assembly. Furthermore, better stability and accuracy can be achieved during angle adjustment. Attached Figure Description

[0024] According to this embodiment, the radar device mounting bracket assembly 100 includes: a first bracket 110, fixed to the vehicle body, and including a first connecting portion 111 and a second connecting portion 112 connected to the radar device R and disposed on the front surface 110a of the first bracket 110; a second bracket 120, including a third connecting portion 121 connected to the radar device R and movably connected to the first bracket 110 relative to the first bracket 110 in a forward or backward manner; and an adjusting member 130, connected to the first bracket 110 and the second bracket 120 to move the second bracket 120 relative to the first bracket 110.

[0025] The following reference Figure 1 The radar device R is connected to the vehicle body via the radar device mounting bracket assembly 100 according to this embodiment. A first bracket 110 is connected to and fixed to the vehicle frame. After the radar device R is connected to the radar device mounting bracket assembly 100 according to this embodiment, the angle of the radar device R can be adjusted by manipulating the adjustment member 130.

[0026] The first bracket 110 may include a first connecting portion 111 and a second connecting portion 112. The second bracket 120 is provided with a third connecting portion 121. The radar device R is connected to the first connecting portion 111 to the third connecting portion 121. The first connecting portion 111 and the second connecting portion 112 may protrude from the front surface 110a of the first bracket 110, and the third connecting portion 121 may protrude from the second bracket 120, extending beyond the front surface 110a of the first bracket 110.

[0027] The second bracket 120 is movably connected to the first bracket 110 in both forward and backward directions relative to the first bracket 110. Therefore, when the second bracket 120 moves forward or backward relative to the first bracket 110, the height of the third connecting portion 121 protruding from the front surface 110a of the first bracket 110 increases or decreases.

[0028] The movement of the second bracket 120 relative to the first bracket 110 can be performed by manipulating the adjustment member 130. In other words, after the radar device R is mounted on the radar device mounting bracket assembly 100 according to this embodiment, the angle of the radar device R can be adjusted by manipulating the adjustment member 130. According to this embodiment, the angle of the radar device can be adjusted using such a simplified structure, which reduces the number of parts, saves raw materials and manufacturing costs, and simplifies assembly compared to conventional techniques. It can also reduce errors in the assembly process to improve quality and achieve better accuracy and stability during angle adjustment.

[0029] According to an embodiment, the first connecting portion 111, the second connecting portion 112, and the third connecting portion 121 are connected to the radar device R via ball joints, such that the angle of the radar device R can be adjusted by manipulating the adjusting member 130 to move the second bracket 120 forward or backward relative to the first bracket. For example, as shown, the ends of the first connecting portion 111, the second connecting portion 112, and the third connecting portion 121 have ball studs, and the radar device R can have a socket formed to receive the ball studs. The ball studs can be inserted into the sockets, allowing the radar device R to be connected to the first connecting portion 111, the second connecting portion 112, and the third connecting portion 121. Therefore, as... Figure 2 As shown, when the second bracket 120 moves forward or backward (left or right in the figure), the radar device R can tilt forward or backward relative to the straight line connecting the end of the first connecting part 111 and the end of the second connecting part 112 (see reference numeral C in the figure).

[0030] The following reference Figure 3 The structure of the radar device mounting bracket assembly 100 according to this embodiment is described in more detail. According to the embodiment, the first bracket 110 may have a first through hole 311 extending through the first bracket 110 in the front-rear direction, and a third connecting portion 121 may be inserted into the first through hole 311 and protrude forward relative to the first bracket 110. Accordingly, the third connecting portion 121 may protrude beyond the front surface 110a of the first bracket 110 through the first through hole 311.

[0031] Furthermore, according to the embodiment, the first bracket 110 may have a second through hole 312 extending through the first bracket 110 in the front-rear direction, and the second bracket 120 may have a protruding guide 122 inserted into the second through hole 312 and supported by the first bracket 110. Since the guide 122 is inserted into the second through hole 312 and supported by the first bracket 110, movement of the second bracket 120 relative to the first bracket 110 can be performed stably.

[0032] In other words, as shown in the figure, the second bracket 120 may include a base portion and is shaped such that the third connecting portion 121 and the guide member 122 protrude forward from the base portion. The third connecting portion 121 and the guide member 122 formed on the base portion are inserted into the first through hole 311 and the second through hole 312. The guide member 122 can be inserted into the second through hole 312 to support the movement of the second bracket 120 relative to the first bracket 110, and as the second bracket 120 moves, the angle of the radar device R connected to the third connecting portion 121 is adjusted.

[0033] Furthermore, according to the embodiment, as shown in the figure, a pair of second through holes 312 and multiple guide members 122 can be provided. For example, when the second bracket 120 moves, an external impact may apply torque to the second bracket 120 with the guide member 122 as the central axis. If only one second through hole 312 and one guide member 122 are provided, it may be difficult to counteract the torque. In addition, the second bracket may vibrate, causing the radar device R to shift from its set position. To solve this problem, the first through hole 311, the second through hole 312, the third connecting part 121, and the guide member 122 can be formed into a cross shape, and multiple second through holes 312 and multiple guide members 122 can be provided, thereby effectively counteracting the torque applied to the second bracket 120. The movement of the second bracket 120 can also be stably supported by the guide member 122.

[0034] The following describes an adjustment member 130 for moving the second bracket 120 relative to the first bracket 110. According to an embodiment, the adjustment member 130 may be threadedly connected to either the first bracket 110 or the second bracket 120 while being rotatably but axially fixed to another bracket. Therefore, as the adjustment member 130 rotates, the first bracket 110 or the second bracket 120 moves threadedly in the axial direction of the adjustment member 130, while the other bracket remains axially fixed, thereby allowing the second bracket 120 to move relative to the first bracket 110. A user can adjust the angle of the radar device R by connecting the radar device R to the radar device mounting bracket assembly 100 according to this embodiment and attaching a tool to the adjustment member 130 to rotate the adjustment member 130.

[0035] According to an embodiment, the first bracket 110 may have a first connecting hole 321, the second bracket 120 may have a second connecting hole 322, and the adjusting member 130 may be inserted into the first connecting hole 321 and the second connecting hole 322. The adjusting member 130 may rotate while being inserted into the first connecting hole 321 and the second connecting hole 322, and is threadedly connected to the first bracket 110 or the second bracket 120, and is rotatably but axially fixedly connected to the other bracket.

[0036] According to the embodiments, such as Figure 3 and Figure 4As shown, the adjusting member 130 can be axially fixed relative to the first bracket 110 and threadedly connected to the second bracket 120. Therefore, when rotated, the adjusting member 130 is axially fixed together with the first bracket 110, while only the second bracket 120 moves forward or backward.

[0037] Furthermore, the rotation of the adjusting member 130 relative to the first support 110 can be supported by the bushing 410. For example, the first support 110 can be made of plastic, and the adjusting member 130 can be made of steel. In order to reduce friction and wear caused by the rotation of the adjusting member 130, a bushing 410 can be provided between the adjusting member 130 and the first support 110.

[0038] Furthermore, the fixing member 330, which is axially supported by the first bracket 110, can be connected to the adjusting member 130 to fix the adjusting member 130 axially relative to the first bracket 110. For example, the fixing member 330 can be a retaining ring.

[0039] According to the embodiments, such as Figure 5 and Figure 6 As shown, the adjusting member 130 can be threadedly connected to the first bracket 110 and axially fixed relative to the second bracket 120. Therefore, when the adjusting member 130 rotates, the adjusting member 130 together with the second bracket 120 can move forward or backward while the first bracket 110 is fixed.

[0040] Similarly, the rotation of the adjusting member 130 relative to the second support 120 can be supported by the bushing 410. For example, the bushing 410 can reduce friction and wear between the second support 120, which is made of plastic, and the adjusting member 130, which is made of steel.

[0041] Furthermore, the fixing member 330, which is axially supported by the second bracket 120, can be connected to the adjusting member 130 to fix the adjusting member 130 axially relative to the second bracket 120. For example, the fixing member 330 can be a retaining ring.

[0042] By using such a well-formed radar device mounting bracket assembly, cost savings and a simplified assembly process can be achieved by reducing the number of parts, while quality can be improved by reducing tolerances during assembly, and better stability and accuracy can be achieved during angle adjustment.
