[0059] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0060] In the description of the utility model, it needs to be explained that, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second" and "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0061] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0062] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0063] With the development of intelligent driving technology, the number of sensors arranged inside and outside the vehicle is gradually increasing. Among them, the camera, as a typical sensor with video image capture, recording and transmission function, is widely used in various fields of the whole vehicle, such as alarm system, intelligent driving system, etc. In traditional design, the camera is generally arranged on the outer surface to realize the auxiliary driving function, such as reversing image, driving record, night vision assistance, blind filling camera, etc. With the development of technology, the camera function application is further developed, and the production of electronic rearview mirror, transparent A-pillar camera and other application modes further expands the application of camera in vehicle perception. With the continuous development of technology, the camera is also more and more applied to the intelligent cockpit, used to monitor the inside of the vehicle, suitable for more scenes, and realizes better human-computer interaction.

[0064] In the related art, the camera arranged on the outer surface is generally protruding relative to the vehicle outer shape, which causes certain influence on the vehicle styling and drag. In addition, the camera arranged on the inner surface is mostly fixedly arranged, and in order to protect privacy, some vehicle models increase physical baffles for cockpit monitoring cameras. The hidden camera hidden in the vehicle structure in the non-working state and exposed for work in the working state is also gradually applied.

[0065] In order to ensure the aesthetic effect, the camera is in a non-working state and is integrated with the interior and exterior trim of the whole vehicle, so a cover plate needs to be arranged to ensure the appearance effect. However, the cover plate and the camera are two relatively independent motion structures, the cover plate needs to avoid the motion envelope of the camera, and the motion decoupling of the cover plate and the camera is difficult, generally requiring multiple control signals and two power inputs, and there are defects of complex structure and large overall mechanism space occupation.

[0066] Therefore, the camera assembly provided by the embodiment of the utility model can drive the motion of the cover plate and the camera by using one driving device and a matched transmission mechanism, realize the extension of the camera and the synchronous everted of the cover plate in the working state, and realize the retraction of the camera and the synchronous inward turning of the cover plate in the hidden state, not only can meet the hidden use demand of the camera of the automobile, but also solve or partially solve the problems of complex mechanical mechanism and large overall mechanism space occupation, realize the motion cooperation of the cover plate and the camera, and meet the aesthetic demand.

[0067] The embodiment of the utility model will be described below in combination with Figures 1 to 9 .

[0068] According to the embodiment of the utility model, on the one hand, a camera assembly is provided, which is suitable for moving relative to a mounting environment piece 10, the mounting environment piece 10 is provided with a mounting gap 11, and the camera assembly comprises:

[0069] A camera 80 has a hidden state of being hidden in the mounting environment piece 10 and a working state of being at least partially extended from the mounting gap 11;

[0070] A cover plate 30 moves synchronously with the camera 80 to cover the mounting gap 11 in the hidden state and open the mounting gap 11 in the working state;

[0071] A driving device 50 has an output shaft 51;

[0072] A kinematic pair mechanism has a first rotary connection part and a second rotary connection part arranged at intervals, the first rotary connection part is connected with the output shaft 51, and the second rotary connection part is suitable for rotating around the output shaft 51 and forming a first motion path with a stroke change; the outer periphery surface of the kinematic pair mechanism rotates around the output shaft 51 to form a second motion path with a stroke change;

[0073] The camera motion mechanism 70 and the cover plate motion mechanism 40 are connected with one of the second rotary connection part and the outer periphery surface of the kinematic pair mechanism respectively;

[0074] The camera motion mechanism 70 is suitable for moving along one of the first motion path and the second motion path to drive the camera 80 to switch between the hidden state and the working state;

[0075] The cover plate movement mechanism 40 is adapted to move along the other one of the first movement path and the second movement path to drive the cover plate 30 to switch between the hidden state and the working state.

[0076] In the embodiment, the installation environment piece 10 can be an interior or exterior trim or an exterior styling of a vehicle, and the appearance can be more beautiful by hiding the camera 80 inside the installation environment piece 10.

[0077] The camera assembly further comprises a housing 20 capable of covering the camera 80 and other structural pieces for movement, facilitating integration of all accessories together with the vehicle assembly.

[0078] The cover plate 30 is in clearance fit with the installation environment piece 10 when the camera 80 is in the hidden state to cover the installation gap 11, and the cover plate 30 can open the installation gap 11 when the camera 80 is in the working state so as to extend the camera 80 to the working position.

[0079] In the embodiment, the driving device 50 is a motor, and the output shaft 51 is specifically a motor output shaft.

[0080] The movement pair mechanism refers to a mechanism driven by the driving device 50 to move along a predetermined trajectory, thereby facilitating driving of the camera movement mechanism 70 and the cover plate movement mechanism 40, and further driving of the camera 80 and the cover plate 30 to switch between the hidden state and the working state.

[0081] The movement pair mechanism can be a single component or a group of components. The specific structural form of the movement pair mechanism is described in detail below.

[0082] The camera assembly provided by the embodiment of the utility model has the first rotation connection part and the second rotation connection part which are arranged at intervals, the first rotation connection part is connected with the output shaft 51, the second rotation connection part is adapted to rotate around the output shaft 51 and form the first movement path with stroke change, and the outer circumferential surface of the movement pair mechanism rotates around the output shaft 51 to form the second movement path with stroke change; the camera movement mechanism 70 and the cover plate movement mechanism 40 are connected with one of the second rotation connection part and the outer circumferential surface of the movement pair mechanism respectively. One driving device and the matched transmission mechanism can be used to drive the two structures of the cover plate 30 and the camera 80 to move, realize the extension of the camera 80 in the working state and the synchronous turning-out of the cover plate 30, realize the retraction of the camera 80 in the hidden state and the synchronous turning-in of the cover plate 30, realize the scheme that the two movements of the cover plate 30 and the camera 80 are decoupled by using a single power source, can not only meet the hidden use demand of the camera of the vehicle, but also solve or partially solve the problems of complex mechanical mechanism and large overall mechanism space occupation, realize the movement cooperation of the cover plate and the camera, and meet the aesthetic demand.

[0083] The camera assembly provided by the embodiment of the utility model can realize the stable extension and recovery process of the camera 80, and cooperates with the opening and closing movement of the cover plate 30, only uses a single power source, realizes the decoupling of the movement of the cover plate 30 and the camera 80, and ensures the mutual cooperation of the movement. When the camera 80 is in a hidden state, the cover plate 30 is gap-fitted with the mounting environment piece 10, and after receiving a working command, the driving device 50 works, so that the cover plate 30 is opened outward, and at the same time, the camera 80 is extended to a working position.

[0084] As an optional implementation form, the kinematic pair mechanism can be the eccentric wheel 60.

[0085] The kinematic pair mechanism has a first rotation connection part and a second rotation connection part which are arranged at intervals, the first rotation connection part is connected with the output shaft 51, and the second rotation connection part is adapted to rotate around the output shaft 51 and form a first movement path with a stroke change. Corresponding to the eccentric wheel 60, the eccentric wheel 60 has an axis hole 61 and an eccentric hole 62, the axis hole 61 is arranged at the axis line position of the eccentric wheel 60, and the eccentric hole 62 is arranged away from the axis line position along the radial direction of the eccentric wheel 60. The output shaft 51 of the driving device 50 is connected with the eccentric hole 62, one end of the connecting rod 71 is hingedly connected with the axis hole 61, and with the rotation of the output shaft 51, the eccentric wheel 60 rotates around the eccentric hole 62 as the rotation center. At this time, the axis hole 61 rotates around the eccentric hole 62, and in turn drives one end of the connecting rod 71 to rotate around the eccentric hole 62. Since the connecting rod 71 is a rod with a fixed length, the other end will swing with the rotation around the eccentric hole 62. At this time, the first movement path is the path of the rotation of the axis hole 61 around the eccentric hole 62.

[0086] The outer periphery of the kinematic pair mechanism rotates around the output shaft 51 to form a second movement path with a stroke change. In the embodiment, the outer periphery of the eccentric wheel 60 is circular, but since the eccentric wheel 60 rotates around the eccentric hole 62 as the rotation center, the movement trajectory of a certain point of the outer periphery of the eccentric wheel 60 forms a non-circular trajectory, for example, an elliptical trajectory. At this time, the second movement path is the movement trajectory of a certain point of the outer periphery of the eccentric wheel 60. In the embodiment, by arranging the eccentric wheel transmission rod 45, the end of the eccentric wheel transmission rod 45 is in rolling contact with the outer periphery of the eccentric wheel 60, and by arranging the limiting ring 47 to limit the moving direction of the eccentric wheel transmission rod 45, the eccentric wheel 60 can drive the eccentric wheel transmission rod 45 to move up and down along the Z direction.

[0087] As an implementation form of the deformation, the kinematic pair mechanism can also be a cam structure or a crank rocker structure. Taking the cam structure as an example, the first rotating connection part and the second rotating connection part can be arranged on the cam structure, the first rotating connection part is connected with the output shaft 51, and the second rotating connection part is adapted to rotate around the output shaft 51 and form a stroke-changing first motion path; and the outer peripheral surface of the cam structure rotates around the output shaft 51 to form a stroke-changing second motion path. Further, the camera movement mechanism 70 and the cover movement mechanism 40 are conveniently driven. The specific structure of the cam structure will not be described here again, which can be reasonably deduced by a person skilled in the art under the inspiration of the utility model.

[0088] In addition, the camera movement mechanism 70 and the cover movement mechanism 40 are connected with one of the second rotating connection part and the outer peripheral surface of the kinematic pair mechanism, respectively. Taking the eccentric wheel 60 as an example. The camera movement mechanism 70 can be connected with the shaft hole 61 of the eccentric wheel 60, or can be in rolling contact with the outer peripheral surface of the eccentric wheel 60. Correspondingly, the cover movement mechanism 40 can be in rolling contact with the outer peripheral surface of the eccentric wheel 60, or can be connected with the shaft hole 61 of the eccentric wheel 60. A person skilled in the art can reasonably deduce another embodiment under the inspiration of one embodiment of the utility model, which will not be described here again.

[0089] The shaft hole 61 of the eccentric wheel 60 is used in cooperation with the connecting rod to control the movement of the camera 80, and the outer contour motion envelope of the eccentric wheel 60 is used in cooperation with the connecting rod to control the movement of the cover 30.

[0090] Hereinafter, taking the camera movement mechanism 70 connected with the shaft hole 61 of the eccentric wheel 60 and the cover movement mechanism 40 in rolling contact with the outer peripheral surface of the eccentric wheel 60 as an example, the implementation scheme of the utility model is described.

[0091] In some embodiments, in combination with Figure 5 As shown in the figure, the kinematic pair mechanism includes an eccentric wheel 60, the eccentric wheel 60 is provided with a shaft hole 61 at the position of the shaft center line, and an eccentric hole 62 is provided away from the position of the shaft center line in the radial direction of the eccentric wheel 60, and the output shaft 51 of the driving device 50 is connected with the eccentric hole 62.

[0092] The shaft hole 61 is provided at the position of the shaft center line of the eccentric wheel 60, and the eccentric hole 62 is provided away from the position of the shaft center line in the radial direction of the eccentric wheel 60. The outer peripheral surface of the eccentric wheel 60 is circular.

[0093] As a deformation, the eccentric wheel 60 is replaced by a cam structure, which can also realize the driving function of the driven wheel 72 and the eccentric wheel transmission rod 45, and can optimize the motion rhythm. Here, it will not be described again.

[0094] In some embodiments, in combination with Figure 4 , Figure 6 As shown in the figures, the camera movement mechanism 70 comprises:

[0095] A connecting rod 71, one end of which is hingedly connected to the shaft hole 61, and the other end of which is hingedly connected to the mounting lug 82 of the camera 80;

[0096] A driven rod 73, one end of which is hingedly connected to the mounting lug 82 of the camera 80, and the other end of which is adapted to rotate around the driven rod fixing pin 91.

[0097] One end of the connecting rod 71 is connected to the geometric center of the eccentric wheel 60 through the shaft pin 76. The other end of the connecting rod 71 is hingedly connected to the mounting lug 82 of the camera 80 through the mounting lug pin 77, and in addition, the driven rod 73, the driven wheel 72 and a plurality of mounting lugs 82 are also hingedly connected to the mounting lug pin 77, which will be described in detail below.

[0098] With the rotation of the output shaft 51, the eccentric wheel 60 rotates around the eccentric hole 62 as the center, the shaft hole 61 rotates around the eccentric hole 62, and in turn drives one end of the connecting rod 71 to rotate around the shaft pin 76. At this time, the other end of the connecting rod 71 makes a swinging motion, and in turn drives the mounting lug 82 of the camera 80 to make a swinging motion through the mounting lug pin 77, thereby providing power for the movement of the camera 80 between the working state and the hidden state.

[0099] One end of the driven rod 73 is hingedly connected to the mounting lug 82 of the camera 80, that is, one end of the driven rod 73 is hingedly connected to the other end of the connecting rod 71 through the mounting lug pin 77. The other end of the driven rod 73 is adapted to rotate around the driven rod fixing pin 91, which is fixed at a predetermined position and does not change position. When the other end of the connecting rod 71 makes a swinging motion, the connecting rod 71 drives the mounting lug pin 77 to move, and at this time the driven rod 73 constrains the movement path of the mounting lug pin 77. In turn, it is convenient for the camera 80 to switch between the working state and the hidden state along the predetermined path, and ensures the stability of the movement path of the camera 80.

[0100] In some embodiments, in combination with Figure 6 As shown in the figures, the camera movement mechanism 70 further comprises:

[0101] A suspension rod 75, one end of which is hingedly connected to the suspension rod mounting hole 81 opened in the camera 80, and the other end of which is adapted to rotate around the suspension rod fixing pin 92;

[0102] Among them, the suspension rod mounting hole 81 and the mounting lug 82 are arranged in parallel and spaced apart along the axis.

[0103] Since the camera 80 is matched with the mounting lug pin shaft 77 through the mounting lug 82, there is a risk of self-rotation of the mounting lug 82 around the mounting lug pin shaft 77, which can easily lead to an uncontrollable angle of the camera 80.

[0104] The suspension rod 75 is further provided, one end of the suspension rod 75 is hingedly connected with the suspension rod mounting hole 81 of the camera 80 through the suspension rod pin 79, and the other end is adapted to rotate around the suspension rod fixing pin shaft 92 which is fixed at a preset position and does not change position. Through cooperation with the driven rod 73, the suspension rod 75, the camera 80, the driven rod 73 and the connecting rod 71 form a simple four-bar linkage mechanism, which can drive the camera 80 to extend according to the set trajectory, avoiding the risk of self-rotation of the mounting lug 82 around the mounting lug pin shaft 77.

[0105] In some embodiments, in combination with Figure 3 As shown, the camera 80 is provided with at least two mounting lugs 82.

[0106] The camera movement mechanism 70 further comprises a mounting lug pin shaft 77 which is simultaneously provided in the at least two mounting lugs 82.

[0107] The number of driven rods 73 is at least two to be hingedly connected with different mounting lugs 82.

[0108] By providing the camera 80 with at least two mounting lugs 82 and the number of driven rods 73 being at least two to be hingedly connected with different mounting lugs 82, the camera 80 can be ensured to move around the axis of the mounting lug pin shaft 77 as the rotation axis, avoiding movement interference, reducing the inclination or even jamming of the camera 80, and improving the structural stability.

[0109] The mounting lug pin shaft 77 is connected to the mounting lugs 82 on the opposite side of the camera 80 through the mounting lug pin 78.

[0110] In some embodiments, in combination with Figure 4 As shown, the camera movement mechanism 70 further comprises:

[0111] The driven wheel 72 is in rolling contact with the outer periphery of the eccentric wheel 60, and the connecting rod 71 and the driven wheel 72 are both hingedly connected with the mounting lug 82.

[0112] By providing the driven wheel 72 and making the driven wheel 72 in rolling contact with the outer periphery of the eccentric wheel 60, the driven wheel 72 can be ensured to rotate synchronously under the driving of the eccentric wheel 60, thereby making the rotation of the camera 80 around the mounting lug pin shaft 77 more smooth and avoiding jamming.

[0113] It is worth pointing out that the above is only for one embodiment of the structure of the utility model, some structural adjustment is made in the above mechanism and still can realize the corresponding action and function required by the design purpose. For example, remove the driven wheel 72, other structures remain unchanged, rely on the coupling movement of the connecting rod 71 and the driven rod 73 under the mounting ear pin shaft 77, constitute the crank rocker structure, the camera assembly of the embodiment can still realize the switching of the cover plate and the camera between two states.

[0114] In some embodiments, in conjunction with Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 As shown in the figure, the cover plate movement mechanism 40 comprises:

[0115] The eccentric wheel transmission rod 45 is in rolling contact with the outer periphery of the eccentric wheel 60 at one end, and the other end is hinged with the sliding block 43; the cover plate 30 is provided with a guide rail 31, and the sliding block 43 is slidingly arranged in the guide rail 31;

[0116] The rotating rod 42 is hingedly connected to the cover plate mounting ear 32 provided on the cover plate 30 at one end, and is adapted to rotate around the rotating rod fixed pin shaft 93 at the other end;

[0117] The traction rod 44 is hingedly connected to the eccentric wheel transmission rod 45 and the rotating rod 42 at both ends.

[0118] In order to realize the synchronous movement of the cover plate 30 and the camera 80, the eccentric wheel transmission rod 45 is arranged, so that the eccentric wheel transmission rod 45 is in rolling contact with the outer periphery of the eccentric wheel 60 at one end, so that the eccentric wheel 60 can drive the eccentric wheel transmission rod 45 to move linearly in the preset direction when the eccentric hole 62 is taken as the center of rotation. The other end of the eccentric wheel transmission rod 45 is hinged with the sliding block 43 through the sliding block pin shaft 48, the cover plate 30 is provided with a guide rail 31, and the sliding block 43 is slidingly arranged in the guide rail 31; the cover plate 30 is moved by the eccentric wheel transmission rod 45, thereby providing power for the movement of the cover plate 30 between the working state and the hidden state.

[0119] The end of the guide rail 31 is provided with a stop block 33 to prevent the sliding block 43 from sliding out of the guide rail 31.

[0120] The cover plate movement mechanism 40 further comprises a rotating rod 42, one end of the rotating rod 42 is hingedly connected to the cover plate mounting ear 32 provided on the cover plate 30, and the other end is adapted to rotate around the rotating rod fixed pin shaft 93; so that the cover plate 30 takes the cover plate mounting ear 32 as the rotating hinge point, so that when the sliding block 43 slides relative to the guide rail 31, it can drive the cover plate 30 to overturn. In addition, the rotating rod fixed pin shaft 93 is fixed at a predetermined position and does not change position, which can constrain the movement path of the cover plate 30.

[0121] Further, the cover plate movement mechanism 40 further comprises a traction rod 44, both ends of the traction rod 44 are respectively hingedly connected with the eccentric wheel transmission rod 45 and the rotating rod 42. By arranging the traction rod 44, the movement actions of the eccentric wheel transmission rod 45 and the rotating rod 42 can be associated, the synchronous movement of the two is ensured, and the outturn distance of the side of the cover plate 30 provided with the cover plate mounting lug 32 relative to the mounting gap 11 is constrained.

[0122] The eccentric wheel transmission rod 45 is provided with a transmission rod pin hole 49, and the transmission rod limiting pin 46 penetrates into the transmission rod pin hole 49, so as to rotationally connect the eccentric wheel transmission rod 45 and the traction rod 44.

[0123] The guide rail 31 and the cover plate mounting lug 32 can be integrally formed with the cover plate 30, or are fixedly connected with the cover plate 30 in the form of welding.

[0124] In some embodiments, in combination with Figure 8 As shown, the cover plate movement mechanism 40 comprises a limiting ring 47, which is sleeved on the outer circumferential side of the eccentric wheel transmission rod 45, and the limiting ring 47 is suitable for limiting the movement of the eccentric wheel transmission rod 45 in a predetermined direction.

[0125] The limiting ring 47 is sleeved on the outer circumferential side of the eccentric wheel transmission rod 45, and in the embodiment, the eccentric wheel transmission rod 45 moves vertically along the Z direction under the limitation of the limiting ring 47.

[0126] In some embodiments, in combination with Figure 9 As shown, the cover plate 30 is provided with at least two cover plate mounting lugs 32.

[0127] The cover plate movement mechanism 40 further comprises a cover plate pin shaft 41, which is simultaneously penetrated into the at least two cover plate mounting lugs 32.

[0128] The number of the rotating rod 42 is at least two to be respectively hingedly connected with different cover plate mounting lugs 32.

[0129] By arranging the cover plate 30 with at least two cover plate mounting lugs 32, and the number of the rotating rod 42 is at least two to be respectively hingedly connected with different cover plate mounting lugs 32. Thus, the cover plate 30 can move with the axis of the cover plate pin shaft 41 as the rotation axis, the movement interference is avoided, the situation that the cover plate 30 is inclined or even stuck is reduced, and the structural stability is improved.

[0130] The specific movement process of the camera assembly provided in the embodiment is described in detail below.

[0131] When the driving device 50 receives the opening signal, the eccentric wheel 60 rotates anticlockwise around the output shaft 51, and the connecting rod 71 and the driven rod 73 restrict the driven wheel 72 to rotate anticlockwise around the driven rod fixing pin shaft 91. The driven wheel 72 starts to move along an arc to the right and down under the restriction of the driven rod 73, and moves to the position shown in the figure. Figure 5 Since the mounting ear pin shaft 77 connects the connecting rod 71, the driven wheel 72, the driven rod 73 and the mounting ear of the camera, and the symmetrically arranged driven rod 73 is connected to the mounting ear 82 of the camera through the mounting ear pin shaft 77, the camera 80 starts to move around the driven rod fixing pin shaft 91 with the driven wheel 72. On this basis, since the suspension rod 75 is connected to the suspension rod fixing pin shaft 92 at one end and to the suspension rod mounting hole 81 of the camera at the other end, the suspension rod 75 can drive the camera 80 to extend along the set track until the working position shown in the figure. Figure 7

[0132] At the same time, since the eccentric wheel 60 rotates anticlockwise around the output shaft 51, the eccentric wheel driving rod 45 starts to move downward along the Z direction under the restriction of the limiting ring 47, and drives the sliding block 43 to move downward. Since the sliding block 43 is restricted in the guide rail 31, the sliding block 43 moves downward relative to the guide rail 31. The upper end point of the eccentric wheel driving rod 45 is in contact with the eccentric wheel 60, and at this time, the eccentric wheel driving rod 45 is at the highest point in the Z direction, and the sliding block 43 connected to the lower end point of the eccentric wheel driving rod 45 is at the leftmost end of the guide rail 31 in this state. Since the traction rod 44 connects the eccentric wheel driving rod 45 and the rotating rod 42, the rotating rod 42 rotates around the rotating rod fixing pin shaft 93 during the downward movement of the eccentric wheel driving rod 45, and the other end of the rotating rod 42 is connected to the cover plate mounting ear 32, so that the cover plate mounting ear 32 drives the cover plate 30 to start to move, and the cover plate 30 performs a flip motion relative to the cover plate mounting ear 32. The movement of the cover plate mounting ear 32 and the guide rail 31 determines the movement track of the cover plate 30. Therefore, the eccentric wheel 60 continuously rotates anticlockwise until the cover plate 30 moves to the position shown in the figure, and is completely opened. Figure 9

[0133] When the camera 80 ends the working state, the driving device 50 controls the eccentric wheel 60 to reverse, and the mechanical structure is opposite to the above-mentioned opening movement process until it returns to the initial position.

[0134] It is worth pointing out that the above is only a structure description of one embodiment of the utility model, and some structural adjustments can still achieve the corresponding actions and functions required by the design purpose in the above mechanism.

[0135] ​​In addition, it is pointed out that the working direction of the above-mentioned embodiment is not limited to the downward extension of the camera, and the whole system can be rotated to realize the hidden camera function in each direction.

[0136] According to the embodiment of the utility model, on the other hand, a vehicle is also provided, including: vehicle body, and set up on vehicle body like above-mentioned camera assembly.

[0137] Obviously, the above-mentioned embodiment is only for clearly illustrating the example, and not the limitation of the embodiment. Although the embodiment of the utility model is described in combination with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations all fall within the scope defined by the utility model.
