[0032] Please refer to Figures 1 to 3 , and now a waterproof structure for a vehicle-mounted millimeter-wave radar provided by an embodiment of the present invention includes:

[0033] A radar housing 1, an opening 11 is provided at the radar housing 1, and a plurality of interfaces are provided in the opening 11;

[0034] A waterproof wire box 2, the waterproof wire box 2 is connected to the opening 11; the waterproof wire box 2 is provided with a plurality of through holes 21 for a circuit 3 to enter;

[0035] A plurality of waterproof connectors 4, all the waterproof connectors 4 and all the through holes 21 correspond one by one; each waterproof connector 4 is connected to one through hole 21; a corresponding circuit 3 is provided in each waterproof connector 4.

[0036] In the present invention, by fixing the waterproof wire box 2 at the radar housing 1, waterproofing for each circuit 3 is achieved; in addition, the through holes 21 opened in the present invention can be connected to a plurality of standardized waterproof connectors 4. Thus, after the waterproof connectors 4 and the waterproof wire box 2 are fixed, and the waterproof wire box 2 and the radar housing 1 are fixed, a sealed space is formed inside the entire waterproof wire box 2, improving the protection ability against rain, snow, etc. and avoiding damage to the internal circuit 3.

[0037] In some embodiments, as Figure 1 and 3 shown, connection pieces 22 are respectively provided on both sides where the waterproof wire box 2 is fixed, and the connection pieces 22 are threadedly connected to the radar housing 1. Specifically, the connection pieces 22 are provided with fasteners for passing through bolts or screws, and the connection pieces 22 are fixed to the radar housing 1 through the fasteners. This method ensures a stable connection between the waterproof wire box 2 and the radar housing 1, and helps to protect the electronic components inside the radar from moisture and other environmental factors.

[0038] In some embodiments, as Figure 1 shown, a first sealing ring 211 is provided in each through hole 21, and a corresponding circuit 3 is provided in each first sealing ring 211. Specifically, the circuit 3 is fixed by the first sealing ring 211. The inner ring of the first sealing ring 211 has a shape matching the corresponding circuit 3 so as to tightly wrap the circuit 3 to prevent it from moving or loosening in the through hole 21 and avoid moving due to external vibration or impact.

[0039] In some embodiments, as Figure 4 and 5 shown, all interfaces include a power interface 121, a network interface 122, and an optical fiber interface 123; specifically, one end of the power line 31 facing the radar housing 1 is connected to the power interface 121; one end of the network cable 32 facing the radar housing 1 is connected to the network interface 122; one end of the optical fiber line 33 facing the radar housing 1 is connected to the optical fiber interface 123; the power interface 121 is used to provide the power required by the device. The network interface 122 is used to implement communication between the device and the network. The optical fiber interface 123 is used to support high-speed and long-distance optical fiber communication.

[0040] In some embodiments, as Figure 5 shown, a power connector 311 is provided at one end of the power line 31 facing the radar housing 1, a network connector 321 is provided at one end of the network cable 32 facing the radar housing 1, and an optical fiber connector 331 is provided at one end of the optical fiber line 33 facing the radar housing 1. The function of the power connector 311 is to ensure that the power line 31 can be firmly connected to the power interface 121 while maintaining stable power transmission. The function of the network connector 321 is to ensure that the network cable 32 can achieve stable and high-speed network communication connection with the network interface 122. The function of the optical fiber connector 331 is to ensure that the optical fiber line 33 can achieve optical fiber communication connection with the optical fiber interface 123.

[0041] In some embodiments, as Figure 3 shown, a ring of opening grooves 111 is provided at the opening 11, and a second sealing ring 112 is provided in the opening grooves 111. The setting of the second sealing ring 112 can effectively prevent rain, snow, etc. from penetrating into the radar housing 1 through the gaps.

[0042] In some embodiments, as Figure 1 and 3 shown, the bottom 20 of the waterproof cable box 2 is closely attached to the second sealing ring 112. By squeezing the second sealing ring 112, the sealing performance of the waterproof cable box 2 can be further enhanced, the gap distance can be reduced, the durability can be improved, and the electrical safety can be ensured.

[0043] In some embodiments, as Figure 5As shown in the figure, the waterproof connector 4 includes a locking nut 41, a seal 42 and a connector body 43; a seal 42 is embedded at one end of the connector body 43 facing away from the waterproof junction box 2, and the seal 42 sleeves one end of the line 3; a locking nut 41 is sleeved outside the seal 42, and the locking nut 41 is threadedly connected to one end of the connector body 43. Specifically, the waterproof connector 4 is formed through the following steps:

[0044] When the line 3 needs to be connected to the waterproof junction box 2, first sleeve the seal 42 on the line 3 and ensure it fits tightly. Then, insert one end of the connector body 43 facing away from the waterproof junction box 2 into the seal 42 and ensure it is firmly embedded. Finally, thread the locking nut 41 onto one end of the connector body 43 and fix and lock each line 3 (power line 31, network port connection line 32 and optical fiber line 33) by rotating the locking nut 41. During this process, the seal 42 is tightly compressed between the connector body 43 and the locking nut 41, forming an effective waterproof barrier.

[0045] In some embodiments, an external thread is provided at one end of the waterproof connector 4 facing away from the locking nut 41, and the external thread is threadedly connected to the internal thread at the through hole. During installation, just align the end of the waterproof connector 4 with the external thread to the through hole and rotate it so that its external thread fits tightly with the internal thread of the through hole. This connection method not only simplifies the installation process, but also improves the accuracy and reliability of the installation. At the same time, due to the tight fit between the external thread and the internal thread, it can also effectively prevent impurities such as moisture and dust from seeping in from the joint.

[0046] A vehicle-mounted millimeter-wave radar, the radar structure includes a waterproof structure for the junction box of the vehicle-mounted millimeter-wave radar; by adopting this waterproof structure, the waterproof performance of the millimeter-wave radar structure can be effectively improved, enabling it to be effectively tested in relatively harsh weather such as rainy and snowy weather, and avoiding false alarms and damage to the equipment caused by water seepage.

[0047] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
