[0041] In view of the technical problem that the radar in the prior art adopts a fixed structure and cannot adjust the position, the present disclosure provides a motion structure of a hidden radar for driving the radar 101 ( Figure 2 As shown) rotate, Figure 1 As shown, the motion structure includes:

[0042] The radar protection mechanism 1 is used to fix the radar 101. The radar 101 is arranged inside the radar protection mechanism 1. The radar protection mechanism 1 isolates and protects the radar 101.

[0043] The rotating mechanism 2 and the driving mechanism 3, the radar protection mechanism 1 is connected to the rotating mechanism 2 and the driving mechanism 3 respectively, and the driving mechanism 3 is used to drive the radar protection mechanism 1 to rotate around the rotating mechanism 2, thereby driving the radar 101 to rotate;

[0044] When the radar 101 is at the initial position, the radar 101 is in a closed state; when the radar 101 rotates from the initial position to a certain height, the radar 101 is in an open state.

[0045] Specifically, the embodiment of the present disclosure provides a rotary hidden radar motion structure, the rotary mechanism 2 can be regarded as a rotation point, the movement of the hidden radar always rotates around the rotation point, and the driving mechanism 3 can drive the radar 101 to move through the motor, thereby realizing the opening and closing functions of the radar 101. Compared with other hidden radar motion structures, this structure has low product cost, high space utilization, simple structure, good stability and good appearance.

[0046] As an optional implementation, Figure 1 As shown, the radar protection mechanism 1 includes: an upper cover 102 and a cover body 103; wherein the upper cover 102 is arranged above the radar 101; the cover body 103 includes a bottom plate 1031 and two side cover plates 1032, the bottom plate 1031 is used to place the radar 101, and the two side cover plates 1032 are symmetrically arranged on both sides of the radar 101; Figure 3 As shown, the upper cover 102 and the cover body 103 form an isolation space, and the radar is arranged in the isolation space (the interior of the upper cover 102 is a hollow structure, and the radar is hidden in the upper cover 102. Figure 3 The radar cannot be seen directly in the

[0047] Figure 1 The figure shows a side view of the motion structure of the hidden radar. The side of the upper cover 102 is a trapezoid. The front end of the upper cover 102 (the end close to the radar transmitter) is thicker than the rear end of the upper cover 102, so as to shield the front end of the radar and act as a protective cover. In order to enable the radar protection mechanism 1 to rotate, the rear end of the upper cover 102 is designed to be thinner. The radar 101 can be fixed to the bottom plate 1031 by welding, screws, buckles, etc., and then the sides of the radar 101 are shielded by two side cover plates 1032, so that an isolation space can be formed to prevent the radar from being exposed to the outside and causing damage or being corroded by rain, thereby extending the service life of the radar.

[0048] As an optional implementation, Figure 1 As shown, the upper cover 102 is provided with an opening 1021, and the size of the opening 1021 is adapted to the laser transmitter of the radar 101. Since the radar uses laser as a signal source, the pulsed laser emitted by the laser transmitter hits the trees, roads, bridges and buildings on the ground, causing scattering, and a part of the light wave will be reflected to the receiver of the laser radar. According to the laser ranging principle, the distance from the laser radar to the target point is calculated, and the pulsed laser continuously scans the target object, so that the data of all target points on the target object can be obtained. After the imaging processing is performed with this data, an accurate three-dimensional stereo image can be obtained. Therefore, by retaining an opening 1021 in the upper cover 102, it is possible to protect the radar 101 without affecting the laser transmitter to emit laser, thereby avoiding affecting the detection accuracy of the radar.

[0049] As an optional implementation, Figure 1 As shown, the rotating mechanism 2 includes: a rotating base 201, a rotating shaft 202 ( Figure 2 As shown) and a connecting member 203;

[0050] The bottom of the rotating base 201 is fixed on the base 4 of the motion structure, and the top of the rotating base 201 is connected to the rotating shaft 202. The rotating shaft 202 is connected to the cover body 103 of the radar protection mechanism 1 through a connecting piece 203, for example, welded to the bottom plate 1031 of the cover body 103, thereby connecting the radar protection mechanism 1 and the rotating shaft, so that the radar protection mechanism 1 can rotate around the rotating shaft 202.

[0051] As an optional implementation, Figure 3 As shown, one end of the connecting member 203 is provided with a sleeve 2031 with a hollow structure. The size of the sleeve 2031 is adapted to the size of the rotating shaft 202. The inner diameter of the sleeve 2031 can be slightly larger than the diameter of the rotating shaft 202. The sleeve 2031 is sleeved on the rotating shaft 202, and the other end of the connecting member 203 is connected to the cover body 103.

[0052] As an optional implementation, Figure 1 As shown, a sliding track groove 1033 is respectively provided on the two side cover plates 1032; the driving mechanism 3 includes: a motor 301, two rocker arms 302, and a transmission component 303; wherein, the two rocker arms 302 are respectively provided corresponding to the two sliding track grooves 1033, one end of each rocker arm 302 is connected to the corresponding sliding track groove 1033, and can slide in the sliding track groove 1033; the other end of each rocker arm 1033 is connected to the transmission component 303, and the motor 301 drives the rocker arm 302 to slide in the sliding track groove 1033 through the transmission component 303.

[0053] For example, Figure 4 As shown, the transmission component 303 may be a worm and worm gear combination component, which includes: a worm and a worm gear; wherein, Figure 4 As shown, the worm includes a driving bevel gear 3031 and a first transmission shaft 3032, one end of the first transmission shaft 3032 is connected to the driving bevel gear 3031, and the other end is connected to the driving shaft of the motor 301;

[0054] like Figure 4 As shown, the worm gear includes a driven helical gear 3033 and a second transmission shaft 3034. The second transmission shaft 3034 and the first transmission shaft 3032 are perpendicular to each other. The driven helical gear 3033 is sleeved on the second transmission shaft 3034 and meshes with the driving helical gear 3031. Figure 6 As shown, both ends of the second transmission shaft 3034 are respectively connected to the two rocker arms 302 , thereby driving the rocker arms 302 to slide in the sliding track groove 1033 .

[0055] Through the above technical solution, such as Figure 1 As shown, when the hidden radar is turned on, the motor 301 rotates forward to drive the first transmission shaft 3032 of the worm to rotate, and then the active bevel gear 3031 drives the driven bevel gear 3033 meshing with it to rotate, and the second transmission shaft 3034 of the worm gear also rotates accordingly, and the two rocker arms 302 connected to the second transmission shaft 3034 also rotate accordingly, and one end of the rocker arms 302 on both sides of the radar protection mechanism 1 slides along the sliding track groove 1033 on the cover body 103. When the rocker arm 302 slides a certain angle, that is, when it slides from the first end of the sliding track groove 1033 to the second end, the hidden radar rotates to a certain height and is in a fully open position. Figure 3 Shown is the hidden radar fully activated.

[0056] Similarly, during the radar closing process, the motor 301 reverses to drive the first transmission shaft 3032 of the worm to rotate, and then the active bevel gear 3031 drives the driven bevel gear 3033 meshing with it to rotate, and the second transmission shaft 3034 of the worm gear also rotates accordingly, and the two rocker arms 302 connected to the second transmission shaft 3034 also rotate accordingly, and one end of the rocker arm 302 slides along the sliding track groove 1033 on the cover body 103. When the rocker arm 302 slides a certain angle, that is, when it slides from the second end of the sliding track groove 1033 to the first end, the hidden radar rotates to the initial position and returns to the closed state.

[0057] The worm gear structure is often used to transmit motion and power between two staggered axes. The worm wheel and the worm are equivalent to the gear and the rack in their middle plane, and the worm is similar in shape to the screw. The advantages of the worm gear structure are: a large transmission ratio can be obtained; the worm transmission is equivalent to the spiral transmission, which is a multi-tooth meshing transmission, so the transmission is smooth and the noise is very small; it has self-locking properties. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm can drive the worm wheel, but the worm wheel cannot drive the worm. Its reverse self-locking property can play a safety protection role.

[0058] As an optional implementation, Figure 1 As shown, the sliding track groove 1033 is arc-shaped, the height of the first end 1033a of the sliding track groove 1033 is greater than the height of the second end 1033b of the sliding track groove, and the sliding track groove is provided with a driving starting position 1033c, which is higher than the first end 1033a of the sliding track groove. The driving starting position 1033c refers to the position from which the rocker arm 302 starts to drive the entire radar protection mechanism 1 to rotate. During the distance from the first end 1033a of the sliding track groove 1033 to the driving starting position 1033c, only the rocker arm 302 itself rotates, and the radar protection mechanism 1 is not driven to rotate. By retaining a certain rotation margin in this way, it is ensured that the radar protection mechanism 1 is in a stable state before opening and after closing.

[0059] During the radar opening process, when the rocker arm 302 starts to slide, there is an idle rotation with a margin greater than ±1°, that is, the rotation trajectory of the rocker arm itself coincides with the motion trajectory of the radar protection mechanism 1, so that the radar protection mechanism 1 is in a stable state, and then the radar protection mechanism 1 is first unlocked from the locking mechanism 5, and then starts to rotate. When the rocker arm 302 slides a certain angle, the radar protection mechanism 1 is in a fully opened position. After being fully opened, the rocker arm 302 also has a margin greater than ±1° so that the radar protection mechanism 1 does not rotate and remains stable.

[0060] Similarly, during the closing process, the rocker arm 302 has a margin greater than ±1° when it starts to rotate, so that the radar protection mechanism 1 is in a stable state. When it is rotated to an angle greater than the margin, the radar protection mechanism 1 starts to rotate and slowly closes. When it is rotated to a certain angle, the radar protection mechanism 1 will first interact with the locking mechanism 5. After the radar protection mechanism 1 is closed, it will be firmly locked to be in a completely closed state. The rocker arm 302 also has a rotation margin greater than ±1° to keep the radar protection mechanism 1 stable.

[0061] As an optional embodiment, the motion structure further includes a locking mechanism 5, which is arranged at the bottom of the radar protection mechanism 1; Figure 5 As shown, the locking mechanism 5 includes:

[0062] The locking block 501 and the locking pin 502 , the locking block 501 is a hook-shaped object fixed to the bottom of the radar protection mechanism 1 , and the locking pin 502 is fixed by the base 4 of the motion structure.

[0063] In this embodiment, when the rocker arm 302 drives the radar protection mechanism 1 to rotate, it first unlocks the locking mechanism 5 and then starts to rotate. When the rocker arm 302 drives the radar protection mechanism 1 to unlock and slide a certain angle, the radar protection mechanism 1 is in the open state. Similarly, during the closing process, when the rocker arm 302 drives the radar protection mechanism 1 to rotate to a certain angle, the radar protection mechanism 1 will first interact with the locking mechanism 5, and the hook (locking block 501) under the bottom plate 1031 of the radar protection mechanism 1 will interact with the locking pin 502 fixed on the base 4. At this time, the radar protection mechanism 1 will be firmly locked and put into a completely closed state. Locking the radar protection mechanism 1 through the locking mechanism 5 has a protective effect on the radar, preventing it from moving up and down with the vehicle body and causing damage to the radar.

[0064] The present disclosure also provides a radar assembly, including the motion structure of the hidden radar described in any one of the above embodiments. The radar assembly includes a radar 101, a radar protection mechanism 1, a rotating mechanism 2, and a driving mechanism 3; the radar protection mechanism 1 is connected to the rotating mechanism 2 and the driving mechanism 3 respectively, and the driving mechanism 3 is used to drive the radar protection mechanism 1 to rotate around the rotating mechanism 2; when the radar 101 is in the initial position, the radar 101 is in a closed state; when the radar 101 rotates from the initial position to a certain height, the radar 101 is in an open state.

[0065] By designing the car radar to be rotatable, the radar is no longer fixed. When the radar is not in use, it can be hidden to avoid damage caused by long-term exposure. In addition, the space occupied by the radar assembly on the car body can be reduced to improve space utilization. The hidden radar has a simple structure and good stability, which improves the overall aesthetics of the car's appearance.

[0066] The present disclosure also provides a car, including the radar assembly described in any one of the above embodiments. By designing the car radar to be rotatable, the radar is no longer fixed. When the radar is in the initial position, the radar is in a closed state; when the radar is rotated from the initial position to a certain height, the radar is in an open state, thereby realizing the radar on and off functions. When the radar is not needed, the radar can be hidden in the car body through the car's central control platform. On the one hand, the radar is prevented from being damaged by long-term exposure, and on the other hand, the space utilization rate is improved. In addition, the hidden radar has a simple structure, good stability, and can enhance the overall aesthetics of the car's appearance.

[0067] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.

[0068] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
