[0002] The vehicle-mounted slip ring, also known as the slip ring, is a key component of the radar system. Its main function is to realize the transmission of electrical signals between the fixed part and the rotating part. In the vehicle-mounted radar system, in order to be able to rotate 360 ​​degrees to capture all-round targets, the slip ring is used to enable the rotating part to maintain a continuous electrical signal connection with the fixed part.

[0003] In the prior art, such as the conductive slip ring disclosed in publication number CN116470361A, during the operation of the radar system, the conductive contact piece will frequently slide on the conductive ring, causing the conductive contact piece to be subjected to enormous friction and wear pressure during long-term use, resulting in rapid wear of the conductive contact piece. The contact between the worn conductive contact piece and the conductive ring cannot reach an ideal state, and insufficient contact is likely to occur, thereby having a serious adverse effect on the transmission of electrical signals, causing the electrical signals to be interrupted, weakened or distorted during transmission, affecting the normal operation of the radar system and requiring frequent maintenance and parts replacement.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more problems existing in the above solutions. Utility Model Content

[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0036] In addition, the accompanying drawings are merely schematic illustrations of the present application and are not necessarily drawn to scale.

Some of the blocks shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0037] In this exemplary embodiment, a vehicle-mounted slip ring is first provided. Figures 1 to 4 As shown in , the vehicle-mounted slip ring for carrying a vehicle-mounted radar system includes a slip ring 100, a rotating contact assembly 200 and a top seat 400; wherein the slip ring 100 includes a ring body 120, a conductive contact assembly 110 and a bearing 130; the ring body 120 has a first through hole; the conductive contact assembly 110 includes a conductive block 111, a first wire 112, a second wire 113 and a spring 114; the conductive block 111 is movably arranged in the ring body 120, one end of which is exposed to the hole wall of the first through hole, and the other end is connected to the second wire 113 through the first wire 112, and one end of the spring 114 is connected to the conductive block 111 for pushing the conductive block 111 toward the first through hole; the bearing 130 is arranged in the ring body 120, the outer ring is fixedly connected to the ring body 120, and the inner ring is exposed to the wall of the first through hole;

[0038] The rotating contact assembly 200 includes a rotating shaft 210, a conductive ring 220 and a third wire 230; the rotating shaft 210 is movably inserted into the first through hole and fixedly connected to the inner ring of the bearing 130, and the conductive ring 220 is sleeved on the rotating shaft 210, with one side in sliding contact with the conductive block 111 and the other side connected to the third wire 230; optionally, the rotating shaft 210 is in interference connection with the bearing 130 and can rotate in the first through hole.

[0039] The top seat 400 is fixedly disposed on the top of the rotating shaft 210 and is used to place the vehicle-mounted radar system.

[0040] Among them, the conductive ring 220, the third wire 230 and the corresponding conductive contact component 110 are two groups, one group is used to input the electrical signal of the vehicle-mounted radar system into the vehicle control system, and the other group is used to input the electrical signal of the vehicle control system into the vehicle-mounted radar system.

[0041] It should be noted that the third wire 230 is connected to the vehicle-mounted radar system, and the second wire 113 is connected to the vehicle control system. Through the contact between the conductive block 111 and the conductive ring 220, the vehicle-mounted radar system and the vehicle control system are connected to realize the transmission of electrical signals.

[0042] Optional, such as Figure 2 As shown, the ring body 120 has a first through slot inside, and the conductive block 111, the first wire 112, the second wire 113 and the spring 114 are movably disposed in the first through slot. The rotating shaft 210 has a second through slot inside, and the third wire 230 is movably disposed in the second through slot.

[0043] It should be noted that the first wire 112 and the second wire 113 are passed through the ring body 120 to protect the wires. The conductive block 111 can slide in the first through groove. When the end of the conductive block 111 that contacts the conductive ring 220 is worn, the conductive block 111 can be pushed toward the conductive ring 220 by the spring 114 to maintain full contact between the conductive block 111 and the conductive ring 220.

[0044] Further, such as Figure 3 As shown, the spring 114 can be pressed between the conductive block 111 and the second wire 113 , or the spring 114 can be pressed against the conductive block 111 and the stop in the first through groove to continuously push the conductive block 111 .

[0045] Optionally, the second wire 113 is fixed in the first through slot, and the first wire 112 is bent, providing a certain travel space for the conductive block 111. When the spring 114 pushes the conductive block 111, the bent first wire 112 is gradually straightened.

[0046] In one embodiment, it further includes: a protective component 500 connected to the top seat 400, used to cover the outer wall of the ring body 120, thereby protecting the ring body 120 and preventing rainwater, dust and other debris from entering the ring body 120 through the gap.

[0047] Further, such as Figure 4 As shown, the side wall of the top seat 400 has a first thread 410, the top of the protective component 500 has a second through hole, the side wall of the second through hole has a second thread 510, and the first thread 410 is engaged with the second thread 510, thereby fixing the protective component 500 to the top seat 400.

[0048] Optionally, the side wall of the top seat 400 is equal to the side wall of the second through hole in thickness. After the protective component 500 is fixedly connected to the top seat 400, the top surface of the top seat 400 and the top surface of the protective component 500 form a plane. Figure 1 As shown, it is convenient to place the vehicle-mounted radar system.

[0049] In one embodiment, the vehicle-mounted slip ring provided by the present application further includes: a base 300 fixedly disposed on the bottom surface of the ring body 120 for being fixedly connected to the vehicle, thereby fixing the vehicle-mounted slip ring to the vehicle. Optionally, the base 300 is fixedly connected to the vehicle via bolts.

[0050] In one embodiment, the ring body 120 has a through heat dissipation hole 140 .

[0051] Further, such as Figure 4 As shown, there are multiple heat dissipation holes 140 arranged in a ring array around the conductive ring 220.

[0052] It should be noted that the conductive ring 220 generates a large amount of heat due to friction. Each heat dissipation hole 140 and the heat dissipation holes 140 on the ring body 120 dissipate the heat on the conductive ring 220 to prevent the conductive ring 220 from overheating.

[0053] When the vehicle-mounted slip ring provided in the embodiment of the present application is in use, the second wire 113 is connected to the vehicle control system and fixed to the vehicle through the base 300, and then the third wire 230 is connected to the vehicle-mounted radar system, and the vehicle-mounted radar system is fixed on the top seat 400; the acquisition component of the radar system performs omnidirectional rotation capture through the rotating shaft 210. When the contact surface between the conductive block 111 and the conductive ring 220 is worn, under the action of the spring 114, the conductive block 111 is always in full contact with the conductive ring 220 to maintain normal transmission of the electrical signal; the external protective component 500 can protect the ring body 120.
