Description

Technical Field

[0001] The invention relates to the technical field of automobile radar probes, and in particular to an automobile radar probe with a protective structure. Background Art

[0002] With the rapid development of automobile intelligence and autonomous driving technology, the importance of automotive radar as a key sensor for sensing the surrounding environment has become increasingly prominent. However, in complex and changeable road environments, radar probes are easily impacted and contaminated by external factors such as flying stones, mud, water, ice and snow, which can lead to performance degradation or even damage. Existing radar probe protection solutions are mostly simple shielding or wrapping. Although they can reduce direct impact to a certain extent, the protection effect is limited and cannot effectively reduce the probability of damage to automotive radar probes.

[0003] In order to solve the above problems, we propose an automobile radar probe with a protective structure. This device effectively protects the radar probe through multi-level buffering. Summary of the invention

[0004] In order to overcome the shortcomings of existing radar probe protection solutions that are mostly simple shielding or wrapping and have limited protection effects, the present invention provides a car radar probe with a protection structure. The device effectively protects the radar probe through multi-level buffering.

[0005] The technical solution is: a car radar probe with a protective structure, including a mounting tube, a connecting seat slidably connected inside the mounting tube, an electric push rod fixedly connected to the mounting tube, the telescopic end of the electric push rod is fixedly connected to the bottom end of the connecting seat, a guide tube is fixedly connected to the top of the connecting seat, a radar probe is slidably connected inside the guide tube, the radar probe and the connecting seat are connected by electric wires, a first spring is connected between the radar probe and the connecting seat, a sliding ring is slidably connected to the guide tube, a protective cover is fixedly connected to the top of the sliding ring, a second spring is connected between the bottom end of the sliding ring and the top end of the connecting seat, a positioning component is provided on the guide tube and the radar probe, the positioning component is used to position the radar probe to prevent the radar probe from shaking and affecting the detection effect, and a side protection component for protecting from the side is provided on the connecting seat.

[0006] As an improvement of the above solution, the protective cover is made of transparent glass.

[0007] As an improvement of the above-mentioned scheme, the positioning assembly includes ejector rods that are evenly distributed around the circumference, which are slidably connected to the guide cylinder, and the radar probe is slidably connected to positioning rods that are evenly distributed around the circumference, which are in contact with adjacent ejector rods, and a third spring is connected between the positioning rods and the radar probe.

[0008] As an improvement of the above solution, the sliding ring is in a truncated cone shape, and the inner side surface of the sliding ring is inclined to be extruded and matched with the ejector rod.

[0009] As an improvement of the above scheme, the side protection assembly includes side pressure plates that are evenly distributed around the circumference, which are slidably connected to the top of the connecting seat, a fourth spring is connected between the side pressure plate and the connecting seat, and an extension plate is fixedly connected to the side pressure plate.

[0010] As an improvement of the above solution, the sliding ring is in a truncated cone shape, and the outer side surface of the sliding ring is inclined to be extruded and matched with the side pressure plate.

[0011] As an improvement of the above scheme, it also includes a wire clamping assembly for arranging connecting wires, the wire clamping assembly is arranged on the connecting seat, the wire clamping assembly includes a longitudinally symmetrical mounting seat, the longitudinally symmetrical mounting seat is fixedly connected to the connecting seat, a wire clamping frame is rotatably connected to the mounting seat, and a torsion spring is connected between the wire clamping frame and the adjacent mounting seat.

[0012] As an improvement of the above scheme, it also includes a cleaning component for the protective cover, the cleaning component is arranged on the mounting tube, the cleaning component includes a transversely symmetrical guide rail, the transversely symmetrical guide rail is fixedly connected to the top of the mounting tube, a longitudinally symmetrical opening and closing plate is slidably connected between the transversely symmetrical guide rails, a wiping block is fixedly connected to the bottom end of the opening and closing plate, and a fifth spring is connected between the opening and closing plate and the two transversely symmetrical guide rails.

[0013] As an improvement to the above solution, a side where the opening and closing plates are close to each other is provided with an inclined surface extending downward to be pressed and matched with the protective cover.

[0014] As an improvement of the above solution, the wiping block is made of sponge material.

[0015] The present invention has the following advantages: 1. In the initial state, the radar probe is retracted in the installation tube for protection. When detection is required, the connecting seat drives the radar probe to extend, and the protective cover covers the outside of the radar probe, which can prevent the radar probe from being contaminated by sand, ice, snow, mud and water. When the device is impacted, the second spring expands and contracts to control the sliding ring to slide up and down to buffer part of the impact force, and the first spring expands and contracts to control the radar probe to slide up and down to further buffer the remaining impact force. The impact force can be effectively reduced through step-by-step buffering, reducing the probability of damage to the radar probe.

[0016] 2. In the initial state, the locking rod is inserted into the guide tube to fix the position of the radar probe to prevent the radar probe from shaking and affecting the detection effect. When the protective cover is hit and the control sliding ring slides downward, the ejection rod will push the locking rod to slide inward and no longer jam the guide tube, so that the radar probe can slide up and down to buffer the remaining impact force.

[0017] 3. When the device is impacted from the side, the fourth spring expands and contracts to control the side pressure plate to slide inward and outward to buffer part of the impact force. When the side pressure plate slides inward and outward, the sliding ring is squeezed to slide up and down to further buffer the remaining impact force. In this way, the impact on the side of the device can be buffered, and the protection effect on the radar probe is further improved.

[0018] 4. The wire clamp can be rotated inward to clamp the connecting wire to prevent the connecting wire from being pulled and loosened or damaged when the connecting seat is extended and retracted up and down in the installation tube.

[0019] 5. When the protective cover moves up and down, the wiping block keeps in contact with the protective cover, and the stains on the protective cover are wiped by the wiping block to avoid affecting the detection effect of the radar probe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0030] Embodiment 1: A car radar probe with a protective structure, such as Figure 1-Figure 5 As shown, it includes a mounting tube 1, a connecting seat 2, an electric push rod 3, a guide tube 4, a radar probe 5, a first spring 6, a sliding ring 7, a protective cover 8, a second spring 9, a positioning component and a side protection component. The connecting seat 2 is slidably connected in the mounting tube 1, the electric push rod 3 is fixedly connected to the left part of the mounting tube 1, the telescopic end of the electric push rod 3 is fixedly connected to the lower part of the connecting seat 2, the guide tube 4 is fixedly connected to the upper side of the connecting seat 2, the radar probe 5 is slidably connected in the guide tube 4, the radar probe 5 is connected to the connecting seat 2 through an electric wire, the radar probe 5 is connected to the connecting seat 2 with a first spring 6, the sliding ring 7 is slidably connected to the outer side of the guide tube 4, the protective cover 8 is fixedly connected to the upper side of the sliding ring 7, the protective cover 8 is made of transparent glass, the second spring 9 is connected between the lower side of the sliding ring 7 and the upper side of the connecting seat 2, the guide tube 4 and the radar probe 5 are provided with a positioning component, the positioning component is used to position the radar probe 5 to prevent the radar probe 5 from shaking and affecting the detection effect, and the connecting seat 2 is provided with a side protection component for protecting from the side.

[0031] When using the device, the device is fixed at a designated position of the car through the mounting tube 1. In the initial state, the connecting seat 2, the guide tube 4, the radar probe 5, the protective cover 8 and other components are in a state of being retracted into the mounting tube 1. When the car starts, the electric push rod 3 will shorten and drive the connecting seat 2 to slide upward, thereby driving the guide tube 4 and the radar probe 5 and other components to move upward and extend out of the mounting tube 1 for detection. During detection, the positioning component can position the radar probe 5 to prevent the radar probe 5 from shaking and affecting the detection effect, and the protective cover 8 covers the outside of the radar probe 5 to prevent the radar probe 5 from being contaminated by sand, ice, snow, mud and water. When the device is impacted, Under the action of the second spring 9, the sliding ring 7 will drive the protective cover 8 to slide up and down to buffer part of the impact force, and when the sliding ring 7 slides downward, it will also control the positioning component to release the radar probe 5. Under the action of the first spring 6, the radar probe 5 can also slide up and down in the guide tube 4 to further buffer the remaining impact force. The impact force can be effectively reduced through step-by-step buffering, reducing the probability of damage to the radar probe 5. At the same time, the side protection component can also buffer the impact force on the side of the device, further improving the protection effect of the radar probe 5. When the car is turned off, the electric push rod 3 will extend and drive the connecting seat 2 to move downward, thereby driving the radar probe 5 to retract into the mounting tube 1 for protection.

[0032] like Figure 4 As shown, the positioning assembly includes an ejector rod 10, a locking rod 11 and a third spring 12. The upper part of the guide cylinder 4 is slidably connected to four ejector rods 10 that are equidistantly distributed around the circumference. The sliding ring 7 is truncated cone-shaped. The inner side surface of the sliding ring 7 is inclined and squeezed to fit with the ejector rod 10. The lower part of the radar probe 5 is slidably connected to four locking rods 11 that are equidistantly distributed around the circumference. The locking rods 11 are in contact with adjacent ejector rods 10. A third spring 12 is connected between the locking rods 11 and the radar probe 5.

[0033] In the initial state, the locking rod 11 is inserted into the guide cylinder 4, thereby fixing the position of the radar probe 5 and limiting the up and down shaking of the radar probe 5 in the guide cylinder 4 to prevent the shaking of the radar probe 5 from affecting the detection effect during normal use. When the protective cover 8 is hit and controls the sliding ring 7 to slide downward, the sliding ring 7 will squeeze the ejection rod 10 to slide inward, and the ejection rod 10 slides inward to push the locking rod 11 to slide inward, and the third spring 12 is deformed. After the locking rod 11 slides inward, it no longer blocks the guide cylinder 4. At this time, the radar probe 5 can slide in the guide cylinder 4 to buffer the remaining impact force. After the impact force is buffered, under the action of the third spring 12 resetting, the locking rod 11 slides outward and resets and is clamped in the guide cylinder 4, thereby re-locking the position of the radar probe 5 for detection.

[0034] like Figure 5As shown, the side protection assembly includes a side pressure plate 13, a fourth spring 14 and an extension plate 15. The top of the connecting seat 2 is slidably connected with four side pressure plates 13 equidistantly distributed around the circumference. The sliding ring 7 is truncated cone-shaped. The outer side surface of the sliding ring 7 is inclined and squeezed to fit with the side pressure plate 13. The fourth spring 14 is connected between the side pressure plate 13 and the connecting seat 2, and the extension plate 15 is fixedly connected to the side pressure plate 13.

[0035] When using the device, when the connecting seat 2 drives the radar probe 5 to extend upward, the entire side defense assembly will also extend upward out of the mounting tube 1. When the device is impacted from the side, under the action of the fourth spring 14, the side pressure plate 13 will slide inward and outward on the connecting seat 2 to buffer part of the impact force. When the side pressure plate 13 slides inward and outward, it will also squeeze the sliding ring 7 to slide up and down, further buffering the remaining impact force. Under the action of the extension plate 15, the width of the side pressure plate 13 can be expanded to prevent the device from being impacted from the gap between the two side pressure plates 13.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, it also includes a wire clamping assembly for arranging the connecting wires, and the wire clamping assembly includes a mounting seat 16, a wire clamping frame 17 and a torsion spring 18. The lower part of the connecting seat 2 is fixedly connected to a front-to-back symmetrical mounting seat 16, and the wire clamping frame 17 is rotatably connected to the mounting seat 16. A torsion spring 18 is connected between the wire clamping frame 17 and the adjacent mounting seat 16.

[0037] When connecting the connecting wire to the connecting seat 2, the staff controls the wire clamping frame 17 to rotate outward and open, and the torsion spring 18 is deformed. When the connecting wire is connected, the staff releases the wire clamping frame 17. Under the action of the torsion spring 18 resetting, the wire clamping frame 17 rotates inward to clamp the connecting wire, so as to prevent the connecting wire from being pulled and loosened or damaged when the connecting seat 2 is extended and retracted up and down in the installation tube 1.

[0038] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a cleaning component for the protective cover 8, the cleaning component includes a guide rail 19, an opening and closing plate 20, a wiping block 21 and a fifth spring 22, the top of the mounting tube 1 is fixedly connected with a left-right symmetrical guide rail 19, and a front-back symmetrical opening and closing plate 20 is slidably connected between the left and right guide rails 19, and a downwardly extending inclined surface is provided on the side where the opening and closing plates 20 are close to each other for extrusion fit with the protective cover 8, a wiping block 21 is fixedly connected to the lower side of the opening and closing plate 20, and the wiping block 21 is made of sponge, and a fifth spring 22 is connected between the opening and closing plate 20 and the left and right guide rails 19.

[0039] When the connecting seat 2 drives the protective cover 8 to move upward and extend out of the mounting tube 1, the protective cover 8 will first contact the wiping block 21, and then squeeze the opening and closing plate 20 to slide back and open, and the fifth spring 22 will be deformed. When the connecting seat 2 drives the protective cover 8 to move downward and retract into the mounting tube 1, under the action of the fifth spring 22, the opening and closing plate 20 will slide toward each other and reset. In the process of the protective cover 8 moving up and down, the wiping block 21 maintains contact with the protective cover 8, and the stains on the protective cover 8 are wiped by the wiping block 21 to avoid affecting the detection effect of the radar probe 5.
