[0060] Figures 1 to 9 The present invention shows a motion mechanism of a camera 120, which includes a driving element 140, a main shaft 150, a first transmission mechanism 170, and a second transmission mechanism 180. The main shaft 150 is connected to the driving element 140. The first transmission mechanism 170 is connected to the main shaft 150, and the first transmission mechanism 170 is suitable for being connected to the camera 120. The main shaft 150 can drive the camera 120 through the first transmission mechanism 170, so that the camera 120 can move between the retracted position and the extended position along the first direction D1. The second transmission mechanism 180 is connected to the main shaft 150, and the second transmission mechanism 180 is suitable for being connected to the cover plate 130 of the camera 120. The main shaft 150 can drive the cover plate 130 through the second transmission mechanism 180, so that the cover plate 130 can move between the closed position and the open position along the second direction D2.

[0061] According to the movement mechanism of the camera 120 of the present invention, the driving element 140 drives the main shaft 150, and drives the cover plate 130 and the camera 120 through the first transmission mechanism 170 and the second transmission mechanism 180 respectively. Only one driving element 140 is used to drive the movement of the cover plate 130 and the camera 120. The structure is simple, and the camera 120 and the cover plate 130 move in two directions respectively, so that the camera 120 and the cover plate 130 can move synchronously and will not interfere with each other through corresponding coordination, which is convenient for control.

[0062] The utility model also provides a camera device, comprising a housing 100, a camera head 120, a cover plate 130, and a motion mechanism of the camera head 120. The camera head 120 is movably disposed in the housing 100 between a retracted position and an extended position along a first direction D1. The cover plate 130 is covered on the housing 100, and is movably disposed on the housing 100 between a closed position and an open position along a second direction D2 different from the first direction D1.

[0063] According to the camera device of the present invention, it is easy to control the cover plate 130 and the camera head 120 of the camera device, so that the driving of the camera head 120 and the driving of the cover plate 130 will not affect each other, and the failure rate is low.

[0064] The camera device according to the present invention further comprises a shell cover 110 , which is connected to the housing 100 and used to close the housing 100 . The shell cover 110 can preferably be detachably mounted on the housing 100 to facilitate installation and maintenance of components in the housing 100 .

[0065] Reference Figures 7 to 9 The second transmission mechanism 180 is configured as follows: when the camera 120 moves from the retracted position to the extended position, the second transmission mechanism 180 drives the cover plate 130 to move to the open position, so that the cover plate 130 can avoid the camera 120, so that the camera 120 does not interfere with the cover plate 130. The second transmission mechanism 180 is configured as follows: when the camera 120 moves from the extended position to the retracted position, the second transmission mechanism 180 drives the cover plate 130 to move to the closed position, so as to prevent the camera 120 from interfering with the cover plate 130 moved to the closed position. In general, the cover plate 130 is spaced apart from the camera 120 in the extended position, and the camera 120 is spaced apart from the cover plate 130 in the closed position, so as to prevent interference between the cover plate 130 and the camera 120.

[0066] Specifically, refer to Figure 1 , Figure 2 and Figure 5 The two side walls of the camera 120 perpendicular to the third direction D3 are provided with guide bars 121, which overlap the steps in the housing 100, so that the camera 120 can move relative to the housing 100 along the first direction D1. The housing 100 is provided with an opening 101. When the camera 120 is in the extended position, the camera 120 protrudes from the housing 100 through the opening 101, so that the camera 120 has a good field of view. Figure 1 , Figure 4 and Figure 5As shown, the housing 100 and the housing cover 110 are both provided with a limit block 102, and the limit block 102 is arranged on the inner wall of the housing 100 and the housing cover 110 perpendicular to the third direction D3, and the limit block 102 is arranged along the second direction D2. The limit block 102 is spaced apart from the inner wall of the housing 100 provided with the opening 101, and the cover plate 130 is penetrated between the limit block 102 and the inner wall of the housing 100 provided with the opening 101. Therefore, when the cover plate 130 is in the closed position, the cover plate 130 closes the opening 101, and when the cover plate 130 is in the open position, the cover plate 130 is located in the housing cover 110, and the opening 101 of the housing 100 is open.

[0067] Further, see Figure 5 The camera device further includes a sealing ring 191, which is disposed on the inner side of the housing 100 and around the opening 101. The sealing ring 191 abuts against the camera 120 in the extended position, and the sealing ring 191 abuts against the cover plate 130 in the closed position. In other words, when the cover plate 130 is in the closed position, the side wall of the cover plate 130 facing the opening 101 abuts against the sealing ring 191, so that the housing 100 is sealed, which is beneficial to prevent external dust, impurities and rainwater from entering the housing 100. When the camera 120 is in the extended position, the camera 120 abuts against the sealing ring 191, so when the camera 120 is working, external dust, impurities and rainwater still do not enter the housing 100, thereby maintaining the cleanliness of the environment inside the housing 100.

[0068] Reference Figure 1, the main shaft 150 is rotatable relative to the housing 100 and extends along the third direction D3, the driving element 140 can be selected as a motor, and the driving element 140 is fixed relative to the housing 100. The motion mechanism of the camera 120 also includes a reduction mechanism 160, and the reduction mechanism 160 includes a first worm 161, a second worm 162, a first worm wheel 163, and a second worm wheel 164. The first worm 161 is connected to the output shaft of the driving element 140 and extends along the first direction D1. The second worm 162 extends along the second direction D2 and is rotatable relative to the housing 100. The first worm wheel 163 is sleeved on the second worm 162 and is fixed relative to the second worm 162, and the first worm wheel 163 is meshed with the first worm 161. The main shaft 150 extends along the third direction D3, the second worm wheel 164 is sleeved on the main shaft 150 and meshed with the second worm 162, and the second worm wheel 164 is fixed relative to the main shaft 150. When the driving element 140 is started, the driving element 140 drives the first worm 161, and the rotation of the first worm 161 drives the first worm wheel 163, so that the second worm 162 rotates, and then drives the main shaft 150 to rotate through the second worm wheel 164, thereby finally driving the cover 130 and the camera 120 respectively, and the reduction mechanism 160 is additionally arranged, and through two-stage reduction, the torque transmitted to the main shaft 150 is increased to prevent the driving element 140 from having difficulty in synchronously driving the camera 120 and the cover 130.

[0069] Further, see Figures 1 to 3 The first transmission mechanism 170 includes a first transmission gear 171 and a first rack 172. The first transmission gear 171 is sleeved on the main shaft 150 and rotates synchronously with the main shaft 150. The first rack 172 is parallel to the first direction D1, and the first rack 172 is fixed to the camera 120 by a fastener 183. The first rack 172 is meshed with the first transmission gear 171. When the main shaft 150 rotates, the first transmission gear 171 rotates, and the camera 120 is driven to move along the first direction D1 through the first rack 172.

[0070] Further, see Figures 1 to 4 The second transmission mechanism 180 includes a second transmission gear 181 and a second rack 182. The second transmission gear 181 is sleeved on the main shaft 150 and fixed to the main shaft 150. The second rack 182 is parallel to the second direction D2 and fixed to the cover plate 130. The second rack 182 is meshed with the second transmission gear 181. When the main shaft 150 rotates, the second transmission gear 181 rotates, thereby driving the cover plate 130 to move along the second direction D2 through the second rack 182.

[0071] In order to prevent interference between the cover plate 130 and the camera 120 (i.e., when the camera 120 is in the extended position, the cover plate 130 is also in the closed position), the motion mechanism of the camera 120 according to the present invention is divided into two stages when it is started. Figure 7 and Figure 8 As shown, the first stage is that the camera 120 moves from the retracted position to the extended position, and at the same time, the cover 130 moves from the closed position to the open position; Fig. 9 As shown, the second stage is that after the cover 130 stops moving at the open position, the camera 120 continues to move until the camera 120 is located at the extended position.

[0072] According to the utility model, the movement mechanism of the camera 120 is divided into two stages when closing. In the first stage, the cover 130 stops at the open position, and the camera 120 moves from the extended position to the retracted position; in the second stage, the cover body moves from the open position to the closed position, and the camera 120 continues to move from the extended position to the retracted position.

[0073] Therefore, through the above arrangement, when the movement mechanism of the camera 120 according to the present invention is started and shut down, the camera 120 and the cover plate 130 will not interfere with each other.

[0074] To achieve the above purpose, the second transmission gear 181 can be selected as an incomplete gear, and the second transmission gear 181 is configured to mesh with the second rack 182 during the process of the cover plate 130 changing from the closed position to the open position, and when the cover plate 130 is in the open position, the second transmission gear 181 does not mesh with the second rack 182. In detail, when the cover plate 130 stops at the open position, the second transmission gear 181 does not mesh with the second rack 182, so the main shaft 150 has no driving effect on the cover plate 130, preventing the second transmission mechanism 180 from being damaged. The camera device also includes a magnet 190, which is fixed relative to the housing 100. Specifically, the magnet 190 is fixed to the inner top surface of the housing cover 110, and is used to absorb the cover plate 130 or the second rack 182 in the open position, so that when the second transmission gear 181 does not mesh with the second rack 182, the cover plate 130 can stop at the open position. Preferably, the cover plate 130 is made of plastic, and the second rack 182 is made of metal. When the cover plate 130 is in the open position, the second rack 182 contacts and adsorbs the magnet 190 .

[0075] Further, see Figure 3 The diameter of the first transmission gear 171 is smaller than the diameter of the second transmission gear 181. Therefore, when the main shaft 150 rotates, the movement speed of the first rack 172 is smaller than the movement speed of the second rack 182. Therefore, when the movement mechanism of the camera 120 is started, the cover 130 will reach the open position before the camera 120 reaches the extended position, further preventing the camera 120 from interfering with the cover 130.

[0076] The utility model also provides a vehicle, comprising a motion mechanism of the camera 120 described above.

[0077] According to the vehicle of the utility model, it is easy to control the cover plate 130 of the motion mechanism of the camera 120 and the camera 120, and the driving of the camera 120 and the driving of the cover plate 130 will not affect each other, and the failure rate is low.
