In order to solve the problems in the prior art, the present invention provides a camera module, in which a housing forms an extension portion extending toward the outside of a connection frame at the front side of the connection frame, which not only can form a shielding structure for the connection frame, but also increases an arrangement space inside the housing.

Fig. 1 is a schematic structural view of a first embodiment of the camera assembly of the present invention. Fig. 2 is a top view of fig. 1. As shown in fig. 1 and 2, one embodiment of the present invention provides a camera assembly comprising:

the housing 10 includes a first housing 16 and a second housing 17, wherein a lens module (not shown in the figure) is disposed in the first housing 16, the second housing 17 extends from a rear side of the first housing 16 in a direction away from the rear side of the first housing 16, a second housing first sidewall 171 of the second housing 17 has a first distance L1 from a first housing first sidewall 161 of the first housing 16, and a second housing second sidewall 172 of the second housing 17 has a second distance L2 from a first housing second sidewall 162 of the first housing 16;

a connection frame 40, the connection frame 40 including a base 45 having a wire passing hole, and first and

second extension arms

46 and 47 extending longitudinally along both ends of the base 45;

wherein the first extension arm 46 is connected to the second housing first side wall 171, and the second extension arm 47 is connected to the second housing second side wall 172;

wherein the first distance L1 and the second distance L2 are defined such that the width L of the camera assembly is < the width l3 of the first housing 16 + the width of the first extension arm 46 + the width of the second extension arm 47.

The first extension arm 46, the second housing first side wall 171, and the base 45 each have a wire hole for wires in the camera assembly to pass through, such as wires of the lens module, the motor, the motherboard of the camera module, etc.

The camera module of the present embodiment has an advantage of reduced width compared to the comparative example shown in fig. 3. Specifically, as shown in fig. 3, the existing camera assembly includes a housing 1 and a link 2 connected to a side wall of the housing 1, wherein the link 2 includes a first extension arm 3 and a second extension arm 4. Typically, for the sake of appearance integrity, the housing 1 has a uniform width along the length direction, then the width of the camera assembly = the width of the housing 1 + the width of the first extension arm 3+ the width of the second extension arm 4.

As shown in fig. 2, the housing of the present embodiment is configured by two parts of the first housing 16 and the second housing 17 arranged along the length direction, and the second housing first side wall 171 of the second housing 17 has a first distance L1 from the first housing first side wall 161 of the first housing 16 and the second housing second side wall 172 of the second housing 17 has a second distance L2 from the first housing second side wall 162 of the first housing 16 in the width direction. That is, the housing 10 has different widths along the length direction.

Wherein, the first distance L1 and the second distance L2 are set to be contracted inwards, and the parts contracted inwards are used for being connected with the first extension arm 46 and the second extension arm 47 of the connecting frame 40, so that the width of the camera assembly of the embodiment=the width of the second housing 17+the width of the first extension arm 46+the width of the second extension arm 47, which is smaller than the width of the first housing 16+the width of the first extension arm 46+the width of the second extension arm 47, thereby achieving the purpose of reducing the overall width of the camera assembly.

Fig. 4 is a top cross-sectional view of a first embodiment of the camera assembly of the present invention, as shown in fig. 4, the camera assembly of the present embodiment further includes a lidar assembly 30, wherein the lidar assembly 30 and the lens module 20 are disposed within the first housing 16 along a width direction (horizontal direction) of the first housing 16.

As can be seen in fig. 4, the first housing 16 has a first cavity therein and the second housing 17 has a second cavity therein, the first and second cavities forming a communicating receiving cavity for receiving the various components of the camera assembly. The lens module 20 is disposed in the first cavity, and a portion of the laser radar assembly 30 is disposed in the first cavity and a portion of the laser radar assembly is disposed in the second cavity.

The first cavity has a larger width than the second cavity, and then the lens module 20 and the laser radar assembly 30 are disposed in the first cavity together, specifically, the length of the laser radar assembly 30 is greater than the length of the lens module 20, so that a portion of the laser radar assembly 30 exceeding the lens module 20 in the length direction can be disposed in the second cavity with a smaller width.

Wherein, the first casing 16 has a front end face 11, and the lens module 20 and the laser radar assembly 30 are disposed on the front end face 11, so that the first cavity is mainly used for accommodating the lens module 20 and the laser radar assembly 30, the width of the first cavity is at least greater than the sum of the widths of the lens module 20 and the laser radar assembly 30, and the width of the second cavity is at least greater than the width of the laser radar assembly 30 and can be smaller than the sum of the widths of the lens module 20 and the laser radar assembly 30, so as to simultaneously achieve the purpose of reducing the width and reasonably arranging.

Further, the length of the first cavity is defined to accommodate at least the lens module 20, and the length of the accommodating cavity is defined to accommodate at least the lidar assembly 30.

In a preferred embodiment, as shown in fig. 4, the laser radar device may further comprise a motor assembly 21, wherein the motor assembly 21 is disposed in the second cavity and located at the rear side of the laser radar assembly 30.

Wherein the second housing first side wall 171 and the first extension arm 46 are on the same side as the lens module 20. Alternatively, the motor assembly 21 may be co-lateral with the second housing first side wall 171 and the first extension arm 46.

For example, the first extension arm 46 may have a cavity inside, while the second extension arm 47 is a non-hollow structure. The first extension arm 46 may be used as a wire end. The cables of the motor assembly 21 may be threaded through the second housing first side wall 171 and the first extension arm 46 in sequence.

Further, when the first extension arm 46 is hollow and the second extension arm 47 is non-hollow, the width of the first extension arm 46 may be greater than the width of the second extension arm 47.

Alternatively, the retracted position of the second housing 17 may be set such that the first distance L1 is greater than the second distance L2, corresponding to the relationship of the widths of the first extension arm 46 and the second extension arm 47. The presence of the first distance and the second distance may provide a connection location for two extension arms of the connection frame 40, while the two sides of the second housing 17 may be set to be different distances to retract corresponding to extension arms having different widths. And the presence of the first distance and the second distance may cause the first housing 16 to form an external appearance of the first extension arm 46 and the second extension arm 47, then corresponding to extension arms having different widths, the two sides of the first housing 16 may be set such that the exposed widths of the first extension arm 46 and the second extension arm 47 are the same to achieve a uniform external appearance.

In one embodiment, as shown in fig. 4, the first distance L1 may be smaller than the width of the lens module 20. That is, at least a portion of the lens module 20 is also in communication with the second cavity to achieve a good ventilation and heat dissipation effect.

In the embodiment of the present invention, the first housing 16 and the second housing 17 may be implemented as a one-piece assembly, or may be implemented as a mutually-spliced structure. For example, as shown in fig. 2, the first housing 16 and the second housing 17 form a butt-joint splice seam 15, and the splice seam 15 may be located at the front end of the connection frame 40, i.e., at a position corresponding to the first cavity.

As shown in fig. 2 and 4, the second housing first side wall 171 and the second housing second side wall 172 may be formed to have arc-shaped edges, and the second housing 17 may be rotatable with respect to the connection frame 40 about the rotation axis 41 in the horizontal direction.

Fig. 5 is a schematic structural view of a second embodiment of the camera assembly of the present invention. Fig. 6 is a top view of fig. 5.

As shown in fig. 5 and 6, one embodiment of the present invention provides a camera assembly comprising:

the camera module comprises a shell 10, a lens module 20 and a laser radar component 30, wherein the lens module 20 and the laser radar component 30 are arranged in the shell 10;

a link 40, the link 40 having a rotation shaft 41 extending inward thereof, the housing 10 being mounted to the rotation shaft 41 so as to have a degree of freedom of rotation about the rotation shaft 41, the rotation shaft 41 extending in a direction coincident with a width direction of the housing 10;

the front end of the housing 10 further has an extension 12, and the extension 12 has a width extending toward the outside of the connection frame 40 in the width direction of the housing 10 to at least partially shield the connection frame 40 from the front side of the connection frame 40.

In the present embodiment, the rear end of the housing 10 is fixed within the range of the link 40 similarly to the prior art, and the range of the link 40 referred to herein refers to the range covered in the cross-sectional direction thereof. That is, the rear end of the housing 10 is fixed within the frame formed by the connection frame 40. The front end of the connecting frame 40 extends further outwards to form the extending part 12 beyond the cross section of the connecting frame 40, so that the extending part 12 can at least partially shield the connecting frame 40 from the front side of the connecting frame 40, thereby forming a more attractive appearance effect.

Further, as shown in fig. 7, the housing of the present embodiment utilizes the part of the space 50 in the width direction of the front of the connection frame 40 beyond the rear end of the housing 10, thereby increasing the corresponding arrangement space inside the housing, and by properly arranging the internal components and utilizing the part of the space, the camera of the present embodiment can achieve the object of reducing the length or volume of the apparatus.

And in a preferred embodiment, the extension 12 extends to both sides in the width direction of the housing 10, and the widths of the extensions extending toward both sides are the same or different, respectively.

The connecting frame 40 of the present embodiment is at least partially covered by the extending portion 12, and the connecting frame in the prior art is fully exposed to the view of the user, so for the sake of symmetry and aesthetic reasons, the width of the connecting frames on both sides of the cavity of the cylinder needs to be set to be uniform, i.e. to be set to be the width on the larger side, which eventually results in the overall width of the camera being too large, and further causes a series of problems caused by the large radius of rotation and the large size of the device. However, the extension portion 12 of the present embodiment may be used to cover the connection frame 40, and the width of the extension portion 12 beyond the connection frame 40 may be determined according to the width of the connection frame 40, so that the extension widths of the two ends may be unnecessarily set to be uniform, and the overall size of the camera may be reduced.

Fig. 8 shows a schematic structural view of a third embodiment of the camera assembly of the present invention. As shown in fig. 8, the housing 10 includes a front case 13 and a rear case 14 that are mutually spliced, and a splice 15 of the front case 13 and the rear case 14 is located at the extension 12.

Specifically, the rear case 14 includes:

a rear case contraction part 142, the rear case contraction part 142 being mounted to the rotation shaft 41 and being located within the range of the connection frame 40, the front end of the rear case contraction part 142 being located at the front side of the connection frame 40;

a rear case extension portion 141, the rear case extension portion 141 extending from a front end of the rear case contraction portion 142 toward an outside of the connection frame 40 along a width direction of the case 10;

the width of the front case 13 corresponds to the width of the rear case extension 141.

Therefore, the splice seam 15 is disposed on the extension portion 12, the opening side of the rear case 14 is disposed on the side of the rear case extension portion 141 with a larger opening radius, and the front case 13 has a uniform cross-sectional dimension as shown in fig. 8, so that the demolding directions and angles of the two case components are not affected, and the yield of the product is improved.

Fig. 9 and 10 show a schematic structural view of a fourth embodiment of the camera assembly of the present invention. As shown in the drawing, a lens module 20 and a lidar assembly 30 are provided at a front end face 11 of the housing 10;

the lens module 20 and the lidar assembly 30 are disposed within the extension 12.

The lens module 20 may further include a light supplementing module 22, where the light supplementing module 22 may be disposed along a vertical direction with the lens module 20, and in general, the width and length of the lens module 20 are greater than those of the light supplementing module 22. In the present embodiment, the lens module 20 and the light supplementing module 22 have larger dimensions as critical dimensions affecting the housing dimensions.

As can be seen from fig. 10, since the lens module 20 and the laser radar assembly 30 are disposed on the front end surface 11 of the housing 10, the front end surface 11 is the front end surface of the extension 12, and the size of the extension 12 is mainly determined by the size of the lens module 20 and the laser radar assembly 30. Accordingly, the width of the extension 12 is equal to or greater than the sum of the widths of the lens module 20 and the lidar component 30.

And, the length of the laser radar component 30 is greater than the length of the lens module 20, and the length of the extension portion 12 corresponds to the length of the lens module 20, and the laser radar component 30 extends from the extension portion 12 to the rear end of the housing 10.

It can be seen that the length of the extension 12 is determined by the length of the lens module 20, and the width is determined by the sum of the widths of the laser radar assembly 30 and the lens module 30. Correspondingly, the width of the rear case extension 141 is determined by the sum of the widths of the lidar component 30 and the lens module 30, and the width of the rear case contraction 142 needs to be larger than the width of the lidar component 30.

Further, it is necessary to arrange elements such as the motor assembly 21 in the rear case shrink portion 142, which can be arranged by utilizing the space of the side and rear of the lidar assembly 30 in the rear case shrink portion 142.

As shown in fig. 9, the connection frame 40 includes:

a connecting beam 42, the connecting beam 42 being disposed above the housing 10;

the wiring end 43, a cable connected to the motor assembly 21 of the camera module is provided in the wiring end 43, the wiring end 43 extends downward from one end of the connecting beam 42, the rotation shaft 41 protrudes from the inner surface of the wiring end 43, and the rotation shaft 41 passes through or is adjacent to the center of gravity of the camera module.

In a preferred embodiment, the connecting frame 40 further comprises:

a non-wiring end 44, the non-wiring end 44 extending downward from the other end of the connecting beam 42, and the rotation shaft 41 protruding relatively from the inner surfaces of the wiring end 43 and the non-wiring end 44.

In this case, since the wiring terminal 43 is generally required to have a cavity for wiring, and the wiring terminal 44 is not required to have a corresponding structure, the thickness (in the width direction of the case 10) W of the wiring terminal 43 _l Typically greater than the thickness W of the non-wire ends 44 _r 。

Based on the present embodiment, the extension 12 of the housing 10 protrudes from the front end of the connection frame 40 beyond the connection frame 40, so that the wire ends 43 and the non-wire ends 44 can be at least partially shielded. Thus, by setting the width of the extension 12, the center of the extension 12 may not coincide with the center of the inner range (hollow portion for housing) of the connection frame 40 as shown in fig. 9, but corresponds to the center of the entire width (outer contour) of the connection frame 40, so that the thicknesses of the portions of the wire ends 43 and the non-wire ends 44 having different thicknesses exposed from the periphery of the extension 12 are the same or are all shielded by the extension 12.

Therefore, the camera assembly of the embodiment can not only utilize the redundant space in the prior art for setting the internal element, but also utilize the part to partially shield the structure of the connecting frame, and realize the purpose of not changing the width of the connecting frame through the shielding, thereby further reducing the whole volume and width of the camera.

The above list of detailed descriptions is only specific to practical embodiments of the present invention, and is not intended to limit the scope of the present invention, and all equivalent embodiments or modifications, such as combinations, divisions or repetitions of features, without departing from the technical spirit of the present invention are included in the scope of the present invention.
