[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] Embodiment 1

[0040] The present embodiment relates to a vehicle-mounted camera module, which can utilize the telescopic design of the camera 5 to avoid the existence of a convex structure on the ceiling, so as to enhance the exquisite perception of the ceiling appearance, and can prevent passengers from being bumped, so as to improve the quality of the entire vehicle.

[0041] In terms of overall structure, combined Figures 1 to 7As shown, the vehicle-mounted camera module of this embodiment is arranged in an installation space 10 on the roof of the vehicle, and the vehicle-mounted camera module includes a sliding component, a driving component 3 and a camera 5.

[0042] The sliding assembly is slidably arranged in the installation space 10, the camera 5 is arranged on the sliding assembly, and the driving assembly 3 is transmission-connected with the sliding assembly. Driven by the driving assembly 3, the sliding assembly can drive the camera 5 to slide up and down, so that the camera 5 extends from the opening 100 at the bottom of the installation space 10 into the vehicle, or retracts from the opening 100 into the installation space 10.

[0043] Based on the above overall introduction, it is worth mentioning that in the specific implementation, the layout position of the vehicle-mounted camera module of this embodiment can be set and adjusted according to the actual installation and functional requirements. For example, it can be arranged on the ceiling screen of the vehicle roof, or it can be arranged directly on the ceiling.

[0044] Furthermore, it should be noted that the expressions related to directions in this embodiment are only used as an exemplary description of this embodiment. In specific implementation, the expressions of directions in this embodiment vary with the different directions in which the vehicle-mounted camera module is set, that is, the directions in this embodiment refer to a relative coordinate system based on the vehicle-mounted camera module.

[0045] exist Figures 1 to 3 In the shown state, the opening 100 is located at the bottom of the installation space 10. In this arrangement, the up-down direction of the vehicle-mounted camera module is the same as the up-down direction of the vehicle. The extension of the camera 5 is a descent, and the retraction of the camera 5 is an ascent. This embodiment is also specifically introduced using this layout as an example.

[0046] Of course, if necessary, the opening 100 can also be set at the top of the installation space 10. At this time, the up and down directions of the vehicle-mounted camera module are opposite to the up and down directions of the entire vehicle. The extension of the camera 5 is rising, and the retraction of the camera 5 is falling.

[0047] It can be understood that by driving the sliding component 3 to move, the camera 5 is driven to slide up and down. The telescopic design of the camera 5 can hide the camera 5 when not in use to avoid adverse effects on the exquisite appearance of the vehicle interior. At the same time, it can also prevent the extended camera 5 from colliding with the passengers, thereby improving the quality of the vehicle.

[0048] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, continue to refer to Figures 1 to 3 As shown, a mounting shell 1 is provided at the roof of the vehicle, a mounting space 10 is formed in the mounting shell 1 , and an opening 100 is provided at the bottom of the mounting shell 1 .

[0050] In a specific implementation, the installation housing 1 includes a bottom housing 11 and a protective cover 12, and the installation space 10 is formed in a cavity surrounded by the bottom housing 11 and the protective cover 12. In addition, the installation housing 1 can be preferably fixed to the top cover sheet metal through a connecting bracket, for example, a mounting ear 111 can be provided on the bottom housing 11 for easy connection with the connecting bracket, and the mounting ear 111 can also be screwed with the connecting bracket, so that not only the detachable design of the installation housing 1 and the connecting bracket can be realized, but also the installation convenience of the installation housing 1 can be improved.

[0051] At the same time, as a preferred implementation form, see Figure 4 and Figure 5 As shown, in this embodiment, the driving assembly 3 includes a motor 31, a reduction mechanism 32 connected to the motor 31, and a power conversion mechanism 33 provided between the reduction mechanism 32 and the sliding assembly. The power conversion mechanism 33 is used to convert the rotational motion of the reduction mechanism 32 into the linear sliding of the sliding assembly.

[0052] The advantage of such an arrangement is that it not only makes the driving assembly 3 simple in structure and easy to design and assemble, but also enables reliable driving of the sliding assembly.

[0053] Secondly, in this embodiment, as a preferred implementation form, the speed reduction mechanism 32 includes a worm gear speed reduction unit 321. The worm 3211 in the worm gear speed reduction unit 321 is connected to the motor 31 by transmission, and the worm wheel 3212 in the worm gear speed reduction unit 321 is rotatably arranged in the installation space 10 and outputs rotational power to the power conversion mechanism 33.

[0054] Here, the speed reduction mechanism 32 adopts a worm gear reduction unit 321 , which can have the advantages of a large speed reduction ratio, a large transmittable torque, and the ability to achieve self-locking, which helps to ensure the driving effect of the drive component 3 .

[0055] Also as a preferred implementation form, in this embodiment, the speed reduction mechanism 32 further includes a gear reduction unit 322. The driving gear 3221 in the gear reduction unit 322 is drivingly connected to the worm gear 3212, and the driven gear 3222 in the gear reduction unit 322 is drivingly connected to the power conversion mechanism 33.

[0056] By further setting up a gear reduction unit 322, it can be ensured that the lifting speed of the camera 5 meets the requirements. It also has the advantages of simple structure, high transmission efficiency and strong bearing capacity, which is beneficial to ensure the reliability of power transmission between the driving component 3 and the sliding component.

[0057] Continue to see Figure 5 As shown, as a preferred implementation form, the power conversion mechanism 33 of this embodiment includes a rack 331 slidably arranged in the installation space 10, and a transmission gear 332 meshingly connected with the rack 331. In the specific structure, the camera 5 is connected to the rack 331, and the transmission gear 332 is transmission-connected to the driven gear 3222.

At the same time, also as a preferred implementation form, the transmission gear 332 is connected to the driven gear 3222 and is coaxially arranged with the driven gear 3222.

[0060] The advantage of such a configuration is that it can improve the integration of the driving assembly 3 and the sliding assembly, facilitate the arrangement of the two in the installation space 10, and also help reduce the overall space occupied by the camera module.

[0061] In addition, in this embodiment, as a preferred implementation form, combined with Figure 2 and Figure 6 As shown, the sliding assembly includes a mounting seat 2 connected to the rack 331, the camera 5 is connected to the mounting seat 2, and a guide mechanism is provided in the installation space 10 to limit the mounting seat 2 to slide along the up and down direction of the vehicle.

[0062] The main benefit of co-arranging the mounting seat 2 and the guide mechanism is that it can facilitate the arrangement of the camera 5 on the sliding component and can also ensure the stability of the sliding component sliding up and down.

[0063] To elaborate, in this embodiment, as a preferred implementation form, the guide mechanism includes at least one group of guide rods 4 arranged in the installation space 10, each group of guide rods 4 is two relatively arranged, and a guide hole 221 is provided on the mounting seat 2 corresponding to each guide rod 4, and each guide rod 4 is inserted into the corresponding guide hole 221.

[0064] Therefore, the guiding mechanism can adopt the guiding rod 4 and the guiding hole 221 that cooperate with each other, so that the structure is simple, the cost is low, and a good guiding effect can be guaranteed.

[0065] Of course, the number of guide rods 4 in this embodiment can be set and adjusted according to actual guiding requirements. Figure 2 and Figure 3In addition to the one group shown in the figure, multiple groups can also be designed. In this case, the number of the guide holes 221 and the number of the guide rods 4 can be kept consistent.
