Technical Field

[0001] This invention relates to the field of radar interface technology, specifically to a signal interface adapter for a radar box. Background Technology

[0002] A radar box is a miniaturized terminal that integrates a radar transceiver module, a feedback unit, and primary signal processing. It can directly output target position, velocity, or point cloud information and is widely used in scenarios such as traffic flow detection, access control triggering, obstacle avoidance for unmanned vehicles, and industrial area monitoring. Its plug-and-play feature allows users to quickly acquire on-site perception data without having to delve into the underlying radar protocol.

[0003] Because different manufacturers use different physical connectors and electrical protocols for their radar boxes, various forms of connectors, such as circular aviation connectors, rectangular latches, network ports, and pin headers, are often used interchangeably in the field. Furthermore, even within the same form, there may be differences in signal definitions, such as differential, single-ended, CAN, and Ethernet. When a radar box needs to be interconnected with receiving devices with different interface specifications, a special adapter must be used, resulting in numerous spare parts, frequent plugging and unplugging, and easy misalignment. This creates a common and prominent interface compatibility problem between radar boxes and receiving devices. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a signal interface adapter for radar boxes, which solves the problem that when radar boxes need to be interconnected with receiving devices of different interface specifications, special adapters must be used, resulting in numerous spare parts, frequent plugging and unplugging, and easy instability in alignment, thus creating a common and prominent problem of inconvenient interface adaptation between radar boxes and receiving devices.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a signal interface adapter device for a radar box, comprising an adapter unit, including a housing, classification components disposed on the front and rear sides of the housing, and a docking component disposed inside the housing to connect and adapt the classification components on the front and rear sides. The classification component has several sets of different types of interface components internally.

[0006] Preferably, the sorting component includes annular grooves on the front and rear sides of the housing, with toothed rings rotatably disposed inside each of the annular grooves on both sides. Several sets of threaded holes are provided on the side of each set of toothed rings that are far apart from each other.

[0008] Preferably, the interface component includes a threaded sleeve with threads inside the threaded hole, and springs are fixedly installed inside the threaded sleeves on both the front and rear sides. A connecting ring is fixedly installed on the side of the spring away from the threaded sleeve. A signal interface female head is embedded inside the connecting ring on the front side, and a first contact point is provided on the side of the signal interface female head near the threaded hole.

[0009] Preferably, a signal interface male connector is embedded inside the rear connecting ring, and a second contact is provided on the side of the signal interface male connector near the threaded hole.

[0013] Preferably, the guide groove is U-shaped, and the guide groove corresponds to the sliding groove.

[0014] Preferably, the distance between the inner walls of the left and right sides of the sliding groove is adapted to the diameter of the threaded sleeve.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a signal interface adapter device for a radar box, which has the following advantages: The radar box's signal interface adapter uses rotatable annular toothed rings on both the front and rear sides of the same housing. This allows for the circumferential distribution of various male and female connectors, which can be quickly switched via a handwheel. The selected connector is then slid down to the central docking assembly via a sliding groove connected to the annular groove. The built-in signal conversion module and relay contacts enable flexible crimping and protocol translation between the circumferentially distributed connectors and the central circuit board. This eliminates the need for frequent replacements of traditional one-to-one adapters, improving on-site interface adaptation efficiency and reducing the number of spare parts and carrying burden.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1-6 The device includes an adapter unit 1, which includes a housing 11, sorting components 12 disposed on the front and rear sides of the housing 11, and a docking component 13 disposed inside the housing 11 to connect and adapt the sorting components 12 on the front and rear sides; the sorting components 12 are provided with several sets of interface components 121 of different types inside.

[0021] In this embodiment, the sorting component 12 includes annular grooves 122 formed on the front and rear sides of the housing 11. Gear rings 123 are rotatably arranged inside the annular grooves 122 on both sides. Several sets of threaded holes 124 are formed on the side of the two sets of gear rings 123 that are far apart from each other. Mounting grooves 125 are formed on the inner sidewalls of the two sets of annular grooves 122. Rotating shafts 126 are rotatably arranged inside the two sets of mounting grooves 125. Gears 127 are fixedly arranged on the outer side of the two sets of rotating shafts 126. The two sets of gears 127 mesh with the two sets of gear rings 123 respectively.

[0022] In this embodiment, handwheels 128 are fixedly connected to the ends of the two sets of rotating shafts 126 that are far apart from each other, and several sets of interface parts 121 are respectively arranged inside several sets of threaded holes 124.

[0023] In this embodiment, the interface component 121 includes a threaded sleeve 1211 threaded inside the threaded hole 124. Springs 1212 are fixedly installed inside the threaded sleeves 1211 on both the front and rear sides. A connecting ring 1213 is fixedly installed on the side of the spring 1212 away from the threaded sleeve 1211. A signal interface female head 1214 is embedded inside the front connecting ring 1213. A first contact point 1215 is provided on the side of the signal interface female head 1214 near the threaded hole 124.

[0024] In this embodiment, a signal interface male connector 1216 is embedded inside the rear connecting ring 1213, and a second contact 1217 is provided on the side of the signal interface male connector 1216 near the threaded hole 124.

[0025] Specifically, such as Figure 6 The first contact 1215 and the second contact 1217 shown are both single-pin pins, arranged in pairs within the same interface component 121: the PIN-A pin is dedicated to DC power supply, and the PIN-D pin carries differential data signals; the radar box is connected to the relay contact 135 via the PIN-A pin, the sensing board 134, and the power bus of the circuit board 132 to supply power to the signal conversion module 138 circuit; the differential data signal is elastically pressed by the PIN-D pin to the relay contact 135, and then led through the microstrip line of the sensing board 134 to the signal conversion module 138 to complete level conversion and protocol encapsulation before being output.

[0026] Working principle: Depending on the output type of the radar box on site, the operator first rotates the corresponding side handwheel 128. The handwheel 128 drives the gear 127 to rotate via the rotating shaft 126. The gear 127 meshes with the gear ring 123, causing the gear ring 123 to rotate in the annular groove 122 until the threaded sleeve 1211 of the required interface part 121 is aligned with the upper opening of the sliding groove 136. At this time, the threaded sleeve 1211 is still engaged with the threaded hole 124, thereby fixing the female or male head to the gear ring 123 and rotating synchronously with it, realizing classified storage and pre-selection positioning.

[0027] Furthermore, once the interface component 121 is pre-selected, the operator screws the threaded sleeve 1211 to disengage it from the threaded hole 124, and then pushes the threaded sleeve 1211 axially along the sliding groove 136. The threaded sleeve 1211 slides down in the guide groove 137 until its front end abuts against the limiting screw sleeve 133. The threaded sleeve 1211 continues to rotate, so that it engages with the limiting screw sleeve 133. During the engagement process, the threaded sleeve 1211 compresses the spring 1212 through the connecting ring 1213, and drives the first contact 1215 on the female side or the second contact 1217 on the male side to move forward until it is elastically pressed against the relay contact 135 on the corresponding side of the sensing plate 134 on the circuit board 132, forming a reliable electrical connection.

[0028] In summary, by using the handwheel 128 to drive the gear 127 to mesh with the gear ring 123, the threaded sleeve 1211 rotates with the gear ring 123 for pre-selection, and then slides down along the sliding groove 136 and presses the first contact 1215 or the second contact 1217 to the relay contact 135 of the induction plate 134 with the help of the spring 1212 and the connecting ring 1213. This allows for quick adaptation and installation within the housing 11, eliminating the need for traditional one-to-one adapters, significantly reducing the number of spare parts, and improving on-site adaptation efficiency. At the same time, the floating compensation of the spring 1212 maintains the contact reliability after multiple insertions and removals.

[0029] Example 2, please refer to Figure 1-9 The classification component 12 includes annular grooves 122 on the front and rear sides of the housing 11. Gear rings 123 are rotatably disposed inside the annular grooves 122 on both sides. Several sets of threaded holes 124 are provided on the side of the two sets of gear rings 123 that are far apart from each other. Mounting grooves 125 are provided on the inner sidewalls of the two sets of annular grooves 122. Rotating shafts 126 are rotatably disposed inside the two sets of mounting grooves 125. Gears 127 are fixedly disposed on the outer side of the two sets of rotating shafts 126. The two sets of gears 127 mesh with the two sets of gear rings 123 respectively.

[0030] In this embodiment, handwheels 128 are fixedly connected to the ends of the two sets of rotating shafts 126 that are far apart from each other, and several sets of interface parts 121 are respectively arranged inside several sets of threaded holes 124.

[0031] In this embodiment, the interface component 121 includes a threaded sleeve 1211 threaded inside the threaded hole 124. Springs 1212 are fixedly installed inside the threaded sleeves 1211 on both the front and rear sides. A connecting ring 1213 is fixedly installed on the side of the spring 1212 away from the threaded sleeve 1211. A signal interface female head 1214 is embedded inside the front connecting ring 1213. A first contact point 1215 is provided on the side of the signal interface female head 1214 near the threaded hole 124.

[0032] In this embodiment, a signal interface male connector 1216 is embedded inside the rear connecting ring 1213, and a second contact 1217 is provided on the side of the signal interface male connector 1216 near the threaded hole 124.

[0033] In this embodiment, the docking component 13 includes an adapter hole 131 opened inside the housing 11. A circuit board 132 is embedded inside the adapter hole 131. Guide grooves 137 are opened on both the front and rear sides of the circuit board 132. Limiting screw sleeves 133 are fixedly installed inside the two sets of guide grooves 137. Sensing plates 134 are fixedly installed inside the two sets of guide grooves 137. Several sets of relay contacts 135 are provided on the outer side of the two sets of sensing plates 134.

[0034] In this embodiment, the inner wall of the adapter hole 131 is provided with two sets of sliding grooves 136, and the tops of the two sets of sliding grooves 136 are respectively connected to two sets of annular grooves 122.

[0035] In this embodiment, the docking component 13 includes an adapter hole 131 opened inside the housing 11. A circuit board 132 is embedded inside the adapter hole 131. Guide grooves 137 are opened on both the front and rear sides of the circuit board 132. Limiting screw sleeves 133 are fixedly installed inside the two sets of guide grooves 137. Sensing plates 134 are fixedly installed inside the two sets of guide grooves 137. Several sets of relay contacts 135 are provided on the outer side of the two sets of sensing plates 134.

[0036] In this embodiment, the inner wall of the adapter hole 131 is provided with two sets of sliding grooves 136, and the tops of the two sets of sliding grooves 136 are respectively connected to two sets of annular grooves 122.

[0037] In this embodiment, the cross-sectional shape of the limiting screw sleeve 133 is set to L-shape, and the signal conversion module 138 is provided on the outside of the circuit board 132.

[0038] Specifically, such as Figure 6 As shown, there are several groups of signal interface female connectors 1214, each representing a different type of signal interface. The first contact 1215 on each group of signal interface female connectors 1214 is distributed in a different position to distinguish between different types of interfaces. The signal interface male connector 1216 is a matching component of the signal interface female connector 1214, so the distribution of the second contact 1217 is the same as the distribution of the first contact 1215.

[0039] In summary, by setting rotatable annular toothed rings 123 on both the front and rear sides of the same housing 11, various specifications of male and female interfaces are distributed circumferentially and can be quickly switched by the handwheel 128. Then, the selected interface is slid down to the central docking component 13 in one go by the sliding groove 136 connected to the annular groove 122. The built-in signal conversion module 138 and relay contact 135 realize the elastic crimping and protocol translation between the circumferentially distributed interfaces and the central circuit board 132. Thus, only two steps are needed to complete the alignment: rotating to select the signal interface and sliding down for installation, avoiding the frequent replacement of traditional one-to-one adapters.

[0040] Example 3, please refer to Figure 1-9 The device includes an adapter unit 1, a housing 11, sorting components 12 disposed on the front and rear sides of the housing 11, and a docking component 13 disposed inside the housing 11 to connect and adapt the sorting components 12 on the front and rear sides; the sorting components 12 are provided with several sets of interface components 121 of different types inside.

[0041] In this embodiment, the sorting component 12 includes annular grooves 122 formed on the front and rear sides of the housing 11. Gear rings 123 are rotatably arranged inside the annular grooves 122 on both sides. Several sets of threaded holes 124 are formed on the side of the two sets of gear rings 123 that are far apart from each other. Mounting grooves 125 are formed on the inner sidewalls of the two sets of annular grooves 122. Rotating shafts 126 are rotatably arranged inside the two sets of mounting grooves 125. Gears 127 are fixedly arranged on the outer side of the two sets of rotating shafts 126. The two sets of gears 127 mesh with the two sets of gear rings 123 respectively.

[0042] In this embodiment, handwheels 128 are fixedly connected to the ends of the two sets of rotating shafts 126 that are far apart from each other, and several sets of interface parts 121 are respectively arranged inside several sets of threaded holes 124.

[0043] In this embodiment, the interface component 121 includes a threaded sleeve 1211 threaded inside the threaded hole 124. Springs 1212 are fixedly installed inside the threaded sleeves 1211 on both the front and rear sides. A connecting ring 1213 is fixedly installed on the side of the spring 1212 away from the threaded sleeve 1211. A signal interface female head 1214 is embedded inside the front connecting ring 1213. A first contact point 1215 is provided on the side of the signal interface female head 1214 near the threaded hole 124.

[0044] In this embodiment, a signal interface male connector 1216 is embedded inside the rear connecting ring 1213, and a second contact 1217 is provided on the side of the signal interface male connector 1216 near the threaded hole 124.

[0045] In this embodiment, the docking component 13 includes an adapter hole 131 opened inside the housing 11. A circuit board 132 is embedded inside the adapter hole 131. Guide grooves 137 are opened on both the front and rear sides of the circuit board 132. Limiting screw sleeves 133 are fixedly installed inside the two sets of guide grooves 137. Sensing plates 134 are fixedly installed inside the two sets of guide grooves 137. Several sets of relay contacts 135 are provided on the outer side of the two sets of sensing plates 134.

[0046] In this embodiment, the inner wall of the adapter hole 131 is provided with two sets of sliding grooves 136, and the tops of the two sets of sliding grooves 136 are respectively connected to two sets of annular grooves 122.

[0047] In this embodiment, the cross-sectional shape of the limiting screw sleeve 133 is set to L-shape, and the signal conversion module 138 is provided on the outside of the circuit board 132.

[0048] Specifically, such as Figure 6 As shown, there are several groups of signal interface female connectors 1214, each representing a different type of signal interface. The first contact 1215 on each group of signal interface female connectors 1214 is distributed in a different position to distinguish between different types of interfaces. The signal interface male connector 1216 is a matching component of the signal interface female connector 1214, so the distribution of the second contact 1217 is the same as the distribution of the first contact 1215.

[0049] Furthermore, according to the type difference, the interface components 121 of the first contact 1215 arrange the first contact 1215 or the second contact 1217 on the end face of the connecting ring 1213 with different circumferential angles and radial levels; the relay contacts 135 on the sensing plate 134 are set in the same angle and level matrix to form a position arrangement that corresponds one-to-one with the interface component 121. When the threaded sleeve 1211 slides along the guide groove 137 to the limiting threaded sleeve 133 and rotates to engage, the first contact 1215 or the second contact 1217 and the relay contact 135 will simultaneously engage only when the angle and level are matched, realizing dual mechanical and electrical identification and preventing mis-insertion.

[0050] Secondly, after bonding is completed, the relay contact 135 leads high-frequency differential pairs, CAN-H / L or Ethernet TX / RX signals to the signal conversion module 138 inside the circuit board 132 via microstrip lines. This module has a built-in programmable impedance matching network, protocol state machine and level conversion array, and automatically calls the corresponding firmware according to the contact position code to complete the physical layer rate, level and polarity self-adaptation.

[0051] Specifically, the signal conversion module 138 processes the input radar data stream as follows: it compensates for the insertion loss introduced by the contact to the microstrip line through a configurable equalizer; it parses the RAW, LVDS, or UDP frames output by the radar box into a unified internal parallel code stream; and it re-encapsulates the data stream into CAN-FD, 1000BASE-T, or RS-485 frame format according to the target interface device 121 type, and outputs it to the signal interface male connector 1216 or the signal interface female connector 1214 via the rear relay contact 135, thereby achieving bidirectional seamless adaptation and conversion of interface standards and data protocols between the radar box and the receiving device.

[0052] In this embodiment, the guide groove 137 is U-shaped, and the guide groove 137 corresponds to the sliding groove 136.

[0053] In this embodiment, the distance between the inner walls on the left and right sides of the sliding groove 136 is adapted to the diameter of the threaded sleeve 1211.

[0054] Working principle: Depending on the output type of the radar box on site, the operator first rotates the corresponding side handwheel 128. The handwheel 128 drives the gear 127 to rotate via the rotating shaft 126. The gear 127 meshes with the gear ring 123, causing the gear ring 123 to rotate in the annular groove 122 until the threaded sleeve 1211 of the required interface part 121 is aligned with the upper opening of the sliding groove 136. At this time, the threaded sleeve 1211 is still engaged with the threaded hole 124, thereby fixing the female or male head to the gear ring 123 and rotating synchronously with it, realizing classified storage and pre-selection positioning.

[0055] Once the interface component 121 is pre-selected, the operator screws the threaded sleeve 1211 to disengage it from the threaded hole 124, and then pushes the threaded sleeve 1211 axially along the sliding groove 136. The threaded sleeve 1211 slides down in the guide groove 137 until its front end abuts against the limiting screw sleeve 133. The threaded sleeve 1211 is rotated to engage with the limiting screw sleeve 133. During engagement, the threaded sleeve 1211 compresses the spring 1212 through the connecting ring 1213, and drives the first contact 1215 on the female side or the second contact 1217 on the male side to move forward until it is elastically pressed against the relay contact 135 on the corresponding side of the sensing plate 134 on the circuit board 132, forming a reliable electrical connection.

[0056] Specifically, the signal conversion module 136 converts the radar box output signal received by the front signal interface female connector 1214 through the internal wiring of the circuit board 132, and outputs it to the signal interface male connector 1216, which has been connected in the same rotation and sliding engagement manner, via the rear sensing board 134 and the relay contact 135, thus completing the interface adaptation and data forwarding between the radar box and the receiving device. When it is necessary to change the interface type, the threaded sleeve 1211 is rotated in the opposite direction to disengage it from the limiting screw sleeve 133. The spring 1212 resets and drives the contact to separate. Then, the original interface piece 121 is pulled out axially, and the handwheel 128 is rotated again to switch to the new interface piece 121. Repeating the above steps can achieve quick blind plugging adaptation.

[0057] In summary, axial locking is achieved through the threaded engagement of the threaded sleeve 1211 and the limiting sleeve 133, ensuring that the first contact 1215 or the second contact 1217 and the relay contact 135 remain in contact under a constant preload, preventing loosening caused by vibration or external force. At the same time, the signal conversion module 138 completes protocol translation through the internal wiring of the circuit board 132, realizing seamless conversion between different interface standards between the radar box and the receiving equipment, ensuring signal integrity and extending the service life of the equipment.
