Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a two-wheel vehicle-mounted millimeter wave radar installation structure. Background Art

[0002] Electric vehicles are a commonly used means of transportation; however, when riding in rainy weather, riders need to wear protective gear such as raincoats and helmets, which increases their blind spots. At the same time, when riding in the rain, the water column in the rearview mirror will also affect the rider's line of sight, making it difficult to detect other vehicles traveling behind the vehicle during lane changes, increasing the risk of riding. Millimeter-wave radar is a radar that works in the millimeter wave band (millimeter wave) for detection; it can effectively detect obstacles within the target range and provide prompts to improve the safety of riding in the rain. Some new two-wheeled vehicle models are already equipped with millimeter-wave radar, but many existing models on the market cannot be directly installed with radar equipment. Utility Model Content

[0005] The bracket includes two parallel plate-shaped support members; the two plate-shaped support members are connected by a connecting rod;

[0006] The radar is fixed on a plate-shaped support, and a connector and signal line for connecting to the two-wheeled vehicle MCU are reserved in the middle of its bottom; the connector and signal line are located in the hollow area formed in the middle of the two plate-shaped support members; the signal line extends to one end and is placed on the connecting rod.

[0007] Preferably, the connecting rod is a hard connecting rod.

[0008] Preferably, a magnet is embedded in the plate-shaped support member for magnetic adsorption with the ferrous metal member.

[0009] Preferably, the fastening point includes a support ring and a limiting ring; the limiting ring is arranged along the inner wall of the support ring for being installed in cooperation with the bolt and the nut.

[0011] The stop bar is arranged along the inner wall of the support ring and is used to limit the bolts and nuts.

[0012] Preferably, the stop bar is an elastic rubber piece.

[0013] Preferably, the limiting ring has a built-in magnet for maintaining magnetic attraction with the nut and bolt.

[0014] Preferably, the hollow portions in the middle of the two plate-shaped support members form air channels for guiding flow.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] The utility model can effectively detect obstacles or other vehicles behind the vehicle by simply fixing the millimeter-wave radar at the rear of the vehicle, making riding safer; when the matching installation structure is fixed, the nut of the bolt will be stuck in the limit ring and maintain magnetic attraction, and the corresponding nut will also be affected by the magnetic attraction; in addition, the gear bar can increase the resistance to the stuck nut, preventing the bolt from loosening during long-term use; causing the radar to fall off and be firmly fixed and not easy to loosen.

[0024] Example 1

[0025] like Figure 1-2 As shown, the utility model proposes a two-wheeled vehicle-mounted millimeter-wave radar installation structure, including a bracket 1 and fastening points 3 arranged at the four corners of the bracket 1; the radar 2 is fixed to the bracket 1 and positioned with bolts, nuts and fastening points 3, so as to be installed on the rear frame of the two-wheeled vehicle; the radar 2 detects whether there is an obstacle behind.

[0026] The bracket 1 includes two parallel plate-shaped support members 11; the two plate-shaped support members 11 are connected by a connecting rod 12;

[0027] The radar 2 is fixed on the plate-shaped support 11, and a connector 21 and a signal line 22 connected to the two-wheeled vehicle MCU are reserved in the middle position of the bottom; the connector 21 and the signal line 22 are located in the hollow area formed in the middle of the two plate-shaped support members 11; the hollow part in the middle of the two plate-shaped support members 11 forms an air channel for diversion; when the equipment is running, the air flow can flow through the air channel to improve the heat dissipation effect of the entire radar 2 structure; at the same time, the shell of the radar 2 can also exchange heat with the air to achieve the heat dissipation function; in this embodiment, the signal line 22 extends to one end and is placed on the connecting rod 12, and the connecting rod 12 forms a support and limiting structure for the signal line 22 to prevent the signal line 22 from being exposed or squeezed to affect signal transmission; one end of the extended signal line 22 is connected to the vehicle's MCU through a dedicated connector to transmit data to the MCU; the MCU can obtain the data of the radar 2 to realize the early warning function by pre-writing the control program, and the existing old models can also obtain the above functions by adding hardware.

[0028] Example 2

[0029] like Figure 2 As shown, the utility model proposes a two-wheel vehicle-mounted millimeter wave radar installation structure, in which the connecting rod 12 is a hard connecting rod; it provides support force for the plate-shaped support members 11 on both sides, and at the same time, the deformation is small to avoid squeezing the shell of the radar 2 and causing damage to the radar 2.

[0030] In this embodiment, a magnet can be embedded in the plate-shaped support member 11 for magnetic adsorption with ferrous metal parts; when the device is fixed on the ferrous material, the installation can be completed by magnetic adsorption, and fasteners such as bolts can be used to further strengthen the device.

[0031] Example 3

[0032] like Figure 5-6 As shown in the figure, the present invention proposes a two-wheeled vehicle-mounted millimeter-wave radar mounting structure. In this embodiment, the fastening point 3 includes a support ring 31 and a retaining ring 33. The retaining ring 33 is arranged along the inner wall of the support ring 31 for mounting with the bolt and nut. The fastening point 3 also includes a stopper 32. The stopper 32 is an elastic rubber member and is arranged along the inner wall of the support ring 31 to limit the position of the bolt and nut. The retaining ring 33 has a built-in magnet to maintain magnetic attraction with the nut and bolt.

[0033] In this embodiment, holes are drilled in advance on the frame at the rear of the vehicle, and then the fastening points 3 are aligned with the various hole positions; bolts are inserted into the fastening points 3 and the pre-drilled positions, and nuts are used to lock them. If the frame itself is made of iron material, the bracket 1 can be directly adsorbed to the frame, and it is more stable after being fixed with bolts and nuts; the nut of the bolt will be stuck in the limit ring 33 and maintain magnetic attraction, and the corresponding nut will also be affected by the magnetic attraction; in addition, the block bar 32 can increase the resistance to the stuck nut to prevent the bolt from loosening during long-term use, causing the radar 2 to fall off.
