Description
TECHNICAL FIELD
[0001] The utility model relates to camera technical field, especially a telescopic camera. BACKGROUND
[0002] Automobile technology develops rapidly, and the iterative progress of automobile automatic driving technology also makes more and more cameras exist on the car, in order to cope with different use environment, the functional requirement needed by the camera also increases more and more.
[0003] In actual use, because the privacy requirement of people is more and more strong now, the conventional OMS (Occupancy Monitoring System, passenger monitoring system) module is not obvious in difference between long-term exposure and use, and cannot intuitively let the passenger feel when he is monitored. In order to protect the privacy of passengers and improve the identification, the existing OMS module gradually adds lifting structure. The conventional lifting structure has no buffer and limiting scheme, due to the lever action generated in the roller lifting, the lens cover will produce unexpected shaking, causing picture shaking, affecting the imaging effect; the lens cover may contact and rub with the outer cover during movement, producing noise; or the product is scratched outside, affecting the appearance, resulting in poor user experience. UTILITY MODEL CONTENT
[0004] Based on the lens cover of the existing telescopic OMS module, the lens cover is easy to be scratched by the outer cover and produce noise, and it is necessary to provide a telescopic camera.
[0005] A telescopic camera, comprising:
[0006] A lens cover having a slide with two open ends;
[0007] A lens body having a light entrance surface, the lens body being slidably arranged in the slide;
[0008] A driving member, the driving member being mounted on the lens cover, the driving member being drivingly connected to the lens body to make the light entrance surface extend out or retract into the slide; and
[0009] A plurality of flexible buffer members, the plurality of flexible buffer members being arranged in the slide around the lens body, the flexible buffer members being fixedly connected to one of the lens body and the lens cover and abutting against the other one to make the lens body and the lens cover arranged in a spaced manner.
[0010] In this way, the lens body shakes less when stretching and retracting, does not contact the lens cover, reduces noise, avoids scratching the outer periphery of the lens body, helps to maintain the flatness of the lens body in use, and improves the user experience. In addition, since the flexible buffer is generally poor in heat dissipation, the interval multi-point arrangement of the flexible buffer also helps to increase the heat dissipation of the lens body and avoid heat accumulation inside the retractable camera.
[0011] In one of the embodiments, the flexible buffer is an elastic piece.
[0012] In this way, it is beneficial to maintain the interval between the lens body and the lens cover in long-term use, avoid loose separation between the lens body and the flexible buffer, reduce the shaking of the lens body, and ensure the user experience.
[0013] In one of the embodiments, the lens cover is provided with a sunken groove at the sliding channel, and the flexible buffer is inserted into the sunken groove; or
[0014] The outer periphery wall of the lens body is provided with a sunken groove, and the flexible buffer is inserted into the sunken groove.
[0015] In this way, the sunken groove increases the contact area between the flexible buffer and the lens cover, and when the flexible buffer is fixed by gluing, it is beneficial to increase the firmness of the connection between the flexible buffer and the lens cover, and reduce the risk of falling off of the flexible buffer.
[0016] In one of the embodiments, the lens cover includes a cylinder body providing the sliding channel and a limiting step fixed to the end of the cylinder body;
[0017] The retractable camera further includes a limiting piece arranged at intervals around the lens body between the limiting step and the lens body, and the limiting piece is fixed to one of the limiting step and the lens body and used to abut the other.
[0018] In this way, the limiting piece fixed to the limiting step further limits the end of the lens body close to the light entrance surface, and increases the stability of the lens body when stretching and retracting.
[0019] In one of the embodiments, the limiting piece is semispherical.
[0020] In this way, the contact area between the limiting piece and the lens body is small, the friction is also small, and the semispherical design will not scratch the outer periphery wall of the lens body, which is beneficial to increase the flatness of the outer periphery wall of the lens body.
[0021] In one of the embodiments, the outer periphery wall of the lens body is annularly provided with a plurality of chamfered segments.
[0022] The limiting member is fixed to the limiting step and abuts against the chamfered section and has an abutting curved surface matching the shape of the chamfered section.
[0023] The limiting of the chamfered section by the abutting curved surface increases the limiting direction of the lens body, i.e. limiting the lens body from both horizontal and vertical directions, further increasing the stability of the lens body during extension and retraction.
[0024] In one embodiment, the abutting curved surface gradually approaches the lens body along the extension direction of the lens body.
[0025] In this way, when the length of the lens body is short and the extension direction is not along the vertical direction, the lens body is prone to be deviated due to the deformation of the flexible buffer when it is retracted in the sliding channel, and the abutting curved surface can correct the deviation of the lens body when it is extended again in the sliding channel.
[0026] In one embodiment, the limiting member is provided with a plurality of air slots located at the abutting curved surface.
[0027] In this way, the abutting area of the limiting member and the lens body is further reduced, reducing the frictional resistance and the noise during sliding.
[0028] In one embodiment, the flexible buffer is fixed to the lens cover, the limiting step is further provided with a guide rail portion extending along the extension and retraction direction of the lens body, the outer peripheral wall of the lens body is provided with a matching portion matching the shape of the guide rail portion, and the matching portion is slidably installed in the guide rail portion.
[0029] In this way, the stability and smoothness of the lens body during extension and retraction are increased.
[0030] In one embodiment, the guide rail portion is a guide rail groove penetrating through the limiting step along the extension and retraction direction, the matching portion is a guide rib fixed to the outer peripheral wall of the lens body and extending along the extension and retraction direction, and the groove width of the guide rail groove gradually increases from the middle portion to both ends.
[0031] In this way, on the one hand, it is convenient to install the lens body into the lens cover, and on the other hand, when the length of the lens body is short, the guide rail groove can also guide the guide rib into the guide groove. BRIEF DESCRIPTION OF DRAWINGS

[0047] Automobile technology is developing rapidly, and the iterative progress of automobile automatic driving technology also makes more and more cameras exist on the car. In order to cope with different use environments, the functional requirements needed by the camera are also increasing.
[0048] In practical use, due to increasingly strong privacy demands, conventional OMS (Occupancy Monitoring System) modules, being constantly exposed, show little difference between when in use and when not in use, failing to intuitively inform passengers when they are being monitored. To protect passenger privacy and improve recognizability, existing OMS modules are increasingly incorporating lifting structures. Conventional lifting structures lack buffering and limit mechanisms. The leverage effect generated during roller lifting can cause unexpected shaking of the lens cover, resulting in image shakiness and affecting imaging quality. Furthermore, the lens cover may rub against the outer casing during movement, generating noise; or it may scratch the lens exterior, affecting appearance and leading to a poor user experience.
[0049] Therefore, it is necessary to provide a retractable camera that has low noise and is not easily shaken.
[0050] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a telescopic camera in one embodiment of this application. Figure 2 for Figure 1The telescopic camera is provided with a lens cover 10, a lens body 20, a driving member and a flexible buffer 30. The lens cover 10 is provided with a slide channel 101 with two open ends. The lens body 20 is provided with a light inlet face 201. The lens body 20 is slidably arranged in the slide channel 101. The driving member is mounted on the lens cover 10 and is drivingly connected to the lens body 20 to make the light inlet face 201 extend out of or retract into the slide channel 101. The flexible buffer 30 is arranged in the slide channel 101 around the lens body 20 at intervals. The flexible buffer 30 is fixedly connected to one of the lens body 20 and the lens cover 10 and abuts against the other one to make the lens body 20 and the lens cover 10 arranged at intervals. Further, the flexible buffer 30 is a flexible member, such as foam, silica gel, cotton, etc. In this way, the lens body 20 shakes less when being extended or retracted and does not contact the lens cover 10, thereby reducing noise and avoiding the lens body 20 from being scratched, which is beneficial to keep the lens body 20 smooth in appearance and improve user experience. In addition, since the flexible buffer 30 usually has poor heat dissipation, the interval arrangement of the flexible buffer 30 is also beneficial to increase heat dissipation of the lens body 20 and avoid heat accumulation inside the telescopic camera. Optionally, the flexible buffer 30 is glued to the slide channel 101 of the lens cover 10 or the peripheral wall of the lens body 20. Further, in one embodiment provided in the present application, the lens cover 10 is provided with a sunken groove 102 (in the figure, the flexible buffer 30 mounted at the sunken groove 102 is hidden in order to show the sunken groove 102) at the slide channel 101. The flexible buffer 30 is inserted into the sunken groove 102. It can be understood that in other embodiments, the sunken groove 102 can also be provided at the peripheral wall of the lens body 20. In this way, in combination with the gluing effect, it is beneficial to prevent the flexible buffer 30 from falling off. It can be understood that in other embodiments, the flexible buffer 30 can also include a rigid mounting portion and a flexible abutting portion. The rigid mounting portion is inserted into the sunken groove 102 with interference and is further fixed by gluing. The flexible abutting portion abuts against the lens body 20.
[0051] Please refer to Figure 3 , Figure 3 for Figure 2The structure schematic diagram of the lens cover 10 and the flexible buffer 30 in the telescopic camera in another view, optionally, in an embodiment provided by the present application, the lens cover 10 comprises a barrel 11 providing a slide 101 and a limiting step 12 fixedly arranged at the end of the barrel 11, specifically, the barrel 11 comprises a lower cover 111 and an upper cover 112 detachably mounted on the lower cover 111 to facilitate the lens body 20 and the driving member to be loaded into the slide 101, the telescopic camera further comprises a limiting member 40 located between the limiting step 12 and the lens body 20 and arranged around the lens body 20 at intervals, the limiting member 40 is fixedly arranged on the limiting step 12 and abuts against the lens body 20, it can be understood that in other embodiments, the limiting member 40 can also be fixedly arranged on the lens body 20 and used to abut against the limiting step 12. In this way, the limiting member 40 fixedly arranged on the limiting step 12 further limits the end of the lens body 20 close to the light entrance face 201, and the stability of the lens body 20 in the telescopic process is increased. Further, in order to reduce the friction between the limiting member 40 and the lens body 20, in this embodiment provided by the present application, the limiting member 40 is in a semispherical shape, so that the contact area between the limiting member 40 and the lens body 20 is small, the friction is also small, and the semispherical design will not scratch the outer peripheral wall of the lens body 20, which is beneficial to increase the flatness of the outer peripheral wall of the lens body 20.
[0052] Please refer to Figure 4 , Figure 4 The structure schematic diagram of the lens cover 10 and the flexible buffer 30 in another embodiment provided by the present application. Optionally, in an embodiment provided by the present application, the outer peripheral wall of the lens body 20 is annularly provided with a plurality of chamfered sections 202, the limiting member 40 is fixedly arranged on the limiting step 12 and abuts against the chamfered sections 202 and has an abutting curved surface 401 matching the shape of the chamfered sections 202. The limiting of the chamfered sections 202 by the abutting curved surface 401 increases the limiting direction of the lens body 20, that is, the lens body 20 is simultaneously limited from the horizontal direction and the vertical direction, and the stability of the lens body 20 in the telescopic process is further increased. Further, when the length of the lens body 20 is short and the telescopic direction of the lens body 20 is not the vertical direction, the complete retraction of the lens body 20 into the slide 101 can cause the limiting member 40 to be separated from the lens body 20 and to be deviated under the neutral action, and when the lens body 20 is extended again, the abutting curved surface 401 can correct the deviation of the lens body 20, on the one hand, the lens body 20 can be in a preset position, and on the other hand, the limiting member 40 can also avoid hindering the lens body 20 from being extended.
[0053] Please refer to Figure 5 , Figure 5 for Figure 4A partial enlarged view of the lens cover 10 at X. Optionally, in order to further reduce the contact area between the limiting member 40 and the lens body 20 to reduce friction, the limiting member 40 is further provided with a plurality of air grooves located at the contact curved surface 401. Further, the air grooves extend along the extension direction and are arranged in sequence perpendicularly to the extension direction, in addition, the cross section of the air grooves is arc-shaped, and the protrusions formed between the air grooves, i.e. the cross section of the part for abutting against the lens body 20, is also arc-shaped, so that the contact curved surface 401 as a whole is wavy, which can further reduce friction. It can be understood that in other embodiments, the extension direction of the air grooves can also be inclined to the extension direction.
[0054] Please refer to Figure 6 and Figure 7 , Figure 6 a front view of the retractable camera in another embodiment of the present application, Figure 7 is Figure 6 a partial enlarged view of the retractable camera at Y. Optionally, in order to increase the stability and smoothness of the lens cover 10 during extension and retraction, the flexible buffer 30 is fixed to the lens cover 10, the limiting step 12 is further provided with a guide rail part 50 extending along the extension direction of the lens body 20, the outer peripheral wall of the lens body 20 is provided with a matching part 60 matching the shape of the guide rail part 50, and the matching part 60 is slidably installed in the guide rail part 50. As Figure 7 shown, the number of the guide rail part 50 and the matching part 60 is two groups, the first group corresponds to the two chamfered sections 202 of the lens body 20, and the second group corresponds to the two side walls of the lens body 20. It can be understood that the second group of guide rail parts 50 and matching parts 60 can be used in combination with the limiting member 40 in Figure 5 to increase the limiting effect of the lens cover 10 on the lens body 20. Specifically, the guide rail part 50 is a guide rail groove 51 extending through the limiting step 12 along the extension direction, the matching part 60 is a guide rib 61 fixed to the outer peripheral wall of the lens body 20 and extending along the extension direction, and the groove width of the guide rail groove 51 gradually increases from the middle to the two ends, which facilitates the lens body 20 to be installed into the lens cover 10, in addition, when the length of the lens body 20 is relatively short, the guide rail groove 51 can also guide the guide rib 61 to enter the guide groove. In order to further increase the smoothness of the cooperation between the guide rib 61 and the guide rail groove 51, the cross section of the guide rail groove 51 is arc-shaped, and the two ends of the guide rail groove 51 are further provided with chamfers.
[0055] The technical features of the above-mentioned embodiments can be combined in any way, in order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered as the scope of the present application.
[0056] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
