Detailed Description

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings of the specification.

The present invention relates to a camera device. As exemplarily shown in fig. 1, a preferred camera device of the present invention comprises a front housing 1, a rear housing 2, and a lens module, wherein the front housing 1 and the rear housing 2 are connected to each other to form a cavity 4 between the front housing 1 and the rear housing 2, the lens module comprises a lens module 5 and a sensor plate 6 behind the lens module 5, the lens module 5 penetrates through a through hole included in the front housing 1 and is fixedly connected to the front housing 1, the sensor plate 6 is located in the cavity 4 and is fixedly connected to the lens module 5 and/or the front housing 1, the sensor plate 6 comprises a sensor 7, the sensor 7 is capable of receiving light transmitted through the lens module 5, wherein,

the camera device further comprises a spring plate penetrating floating type connector, wherein the spring plate penetrating floating type connector comprises two or more PIN PINs 3 and two or more conductive spring plates 8;

the sensor plate 6 comprises two or more perforations 9, on the inner walls of which perforations 9 an electrically conductive material 9a is plated or deposited, which electrically conductive material 9a constitutes part of the electrically conductive pattern of the sensor plate 6;

the PIN needle 3 comprises a PIN front end 3a and a PIN rear end 3b, the PIN needle 3 penetrates through a through hole included in the rear shell 2 and is fixedly connected to the rear shell 2, so that the PIN front end 3a is located in the cavity 4, and the PIN rear end 3b is located outside the cavity 4;

the conductive elastic sheet 8 is positioned in the cavity 4 and is provided with an elastic sheet front end 8a and an elastic sheet rear end 8b, and the elastic sheet rear end 8b comprises a part of the conductive elastic sheet 8 fixedly connected to the PIN needle front end 3 a; the spring front end 8a comprises the part of the conductive spring 8 except the spring rear end 8b, the spring front end 8a is at least partially positioned in the through hole 9 included in the sensor board 6, and forms stable electric connection with the conductive material 9a plated or deposited on the inner wall of the through hole 9 through the elastic force of the conductive spring 8; the elastic piece rear end 8b is fixedly connected to the PIN needle front end 3a and is stably and electrically connected with the PIN needle 3.

In the camera device of the present invention as described above, the form of the front case 1 and the rear case 2 and the manner of connecting them are not particularly limited as long as the front case 1 and the rear case 2 are fixedly connected to each other in a fitting manner to form the cavity 4 therebetween. Here, the term "cavity" means a closed space, the boundary of which should be understood to include: the outer surfaces of the front case 1 and the rear case 2; and a face defined by the boundary formed by the outer surface of the front and rear housings 1 and 2 and the side walls of any holes, channels or slits present on the front and rear housings 1 and 2. The space may be in communication with the outside by means of holes, channels or slits of any shape and size, etc. located on said front shell 1 and/or said rear shell 2. A person skilled in the art may consider that the front housing 1 and the rear housing 2 are fixedly coupled to each other in a cooperative manner by means of various methods such as integral molding, casting, welding, adhesive bonding, screw fastening, rivet fastening, internal and external screw fastening, and/or bayonet fastening. In fact, in the present invention, there may be no definite boundary between the front case 1 and the rear case 2, so that they may be regarded as one integral case, in which case (for example, in the case of integrally molding them), the front case 1 and the rear case 2 may be regarded as a relatively front portion and a relatively rear portion of the integral case.

In the camera device of the present invention as described above, the lens module 5 of the lens module is optionally used to accommodate a lens. The sensor board 6 is located within the cavity such that light passing through the lens module 5 through the optional lens can be transmitted to a sensor 7 contained by the sensor board 6.

In the camera device of the present invention as described above, the sensor board 6 may be fixedly coupled to the rear end of the lens module 5 (as exemplarily illustrated in fig. 1) and/or fixedly coupled to the front case 1 by any means known to those skilled in the art. Preferably, the sensor plate 6 is fixedly attached to the rear end of the lens module 5.

The manner of the fixed connection is not particularly limited as long as the manner enables the light passing through the lens module 5 to reach the sensor 7 included in the sensor board 6. Here, for example, it is conceivable to realize the fixed connection in a plurality of ways, such as by screws, rivets, adhesive, casting, welding, snap-fitting, integral molding or integration. Here, the sensor board 6 and the lens module 5 are preferably fixedly connected by an adhesive to form a lens module.

In the camera device of the present invention as described above, the sensor 7 is a light sensor commonly used in the art, which is capable of receiving a light signal from the lens module 5 and converting the light signal into an electrical signal.

In the camera device of the present invention as described above, a spring-through-plate floating connector is further included, which includes the conductive spring 8, the PIN 3, and a conductive material 9a on the inner wall of the through hole 9 included in the sensor board 6.

In the camera device of the present invention as described above, the conductive elastic piece 8 needs to have certain elastic performance, that is, the conductive elastic piece 8 has a certain elastic modulus, which enables the sensor board 6 to move and/or rotate in multiple directions in X, Y and Z direction due to the elastic modulus of the conductive elastic piece 8 itself in the use position. In addition, the elastic modulus of the conductive elastic piece 8 can also make the elastic piece front end 8a form stable electric connection with the conductive material 9a plated or deposited on the inner wall of the through hole 9 through the elastic modulus (i.e. elastic force) of the conductive elastic piece 8. In addition, the conductive dome 8 is also required to be able to conduct electrical signals from the sensor board 6 and to transmit electrical signals from the outside to the sensor board 6. Here, the person skilled in the art can select the conductive elastic sheet 8 satisfying the above conditions according to the actual application.

Here, the material of the conductive elastic piece 8 is not particularly limited as long as it can achieve the above object. The conductive elastic piece 8 may be made of metal or nonmetal, preferably metal, such as copper or stainless steel. The conductive dome 8 may also be a composite material, such as a non-conductive material coated with a conductive coating. In addition, the conductive elastic sheet 8 may be covered with a non-conductive protective layer, such as a plastic layer, in a portion except for a portion in contact with the PIN front end 3a and the conductive material 9 a.

In the present invention, the term "spring sheet" is to be understood in a broad sense, i.e. the conductive spring sheet 8 of the present invention is not limited to being in a sheet shape, but may also be in a rod shape, or in a partial sheet shape and a partial rod shape.

In addition, as exemplarily shown in fig. 1 to 6, the spring front end 8a preferably comprises a portion having an n-shaped or U-shaped cross-sectional shape, and the portion having an n-shaped or U-shaped cross-sectional shape of the spring front end 8a is located at least partially within the perforation 9 comprised by the sensor board 6, the maximum distance between the two branches of the portion having an n-shaped or U-shaped cross-sectional shape being not smaller than the maximum inner diameter of the perforation 9, and further preferably, the maximum distance between the two branches of the portion having an n-shaped or U-shaped cross-sectional shape being larger than the maximum inner diameter of the perforation 9 when not yet within the perforation 9, i.e., when the conductive spring 8 is in a free state, such that in a use state, the two branches of the portion having an n-shaped or U-shaped cross-sectional shape abut against the conductive material 9a plated or deposited on the inner wall of the perforation 9 due to the elastic modulus of the conductive spring 8 itself, so that the front end 8a of the striking plate forms a stable electrical connection with the conductive material 9a plated or deposited on the inner wall of the through hole 9.

It should be noted here that the ≡ or U-shaped cross-sectional shape should not be construed narrowly as the shape exemplarily shown in fig. 1 to 6, but it may also be formed into other shapes including the ═ or U-shaped cross-sectional shape, such as a circular ring shape, a clip shape, and the like. It is also within the scope of the utility model to have the spring front end 8a in the shape of, for example, a circular or clip.

In particular, as exemplarily shown in fig. 2, both branches of the portion of ≡ section shape are straight, which may enable, among other things, a free movement of the sensor plate 6 in the Z-direction in the position of use, thus absorbing the Z-direction displacement tolerances. The person skilled in the art will understand that the two branches of the U-shaped cross-sectional shaped portion may also be straight (not shown in the figures).

In addition, as shown by way of example in fig. 3 and 5, one or both of the two branches of the portion of n-shaped or U-shaped cross-sectional shape can also be projecting towards the outside of the n-shaped or U-shaped, which is particularly advantageous for making the elastic tab front end 8a form a stable electrical connection, in the position of use, with the conductive material 9a plated or deposited on the inner wall of the perforation 9.

In addition, in the ≡ or U-shaped cross-sectional shape as described above, one or both of the two branches it includes also preferably have a recess dented toward the inside of the ═ or U-shape. As shown in fig. 4, in a preferred clip front end 8a, there is an inwardly depressed recess on one branch of the ≡ shaped cross-sectional shape. The recess preferably has a dimension in the direction of the optical axis of the camera device that can accommodate the thickness of the sensor plate 6 or the height of the inner wall of the through hole 9. Such a recess not only makes it possible to stabilize the electrical connection of the spring front end 8a with the conductive material 9a in the use position, but also makes it less likely that the conductive spring 8 will detach from the through hole 9 of the sensor plate 6 during assembly and use of the camera device of the present invention.

In the camera device of the present invention as described above, the shape of the through hole 9 is not particularly limited, and it may be designed in various shapes such as a circle, a square, an ellipse, an opposite sign, and the like.

In the camera device of the present invention as described above, a conductive material 9a is plated or deposited on the inner wall of the through hole 9, as shown in fig. 2 to 5. The material forming the conductive material 9a is not particularly limited as long as the material can transmit an electric signal from a photosensor to the outside via the conductive material 9a, or transmit an electric signal from the outside to the photosensor via the conductive material 9 a. In particular, the material of the conductive material 9a may be the same as or different from, preferably the same as, the material forming the conductive pattern of the sensor plate 6. The material of the conductive material 9a includes, but is not limited to, copper, gold, silver, nickel, an alloy containing them, and the like.

In the camera device of the present invention as described above, the PIN 3 may be a substance known in the art for achieving electrical conduction or electrical signal transmission in a connector, preferably a metallic substance, more preferably cemented carbide.

In the camera device of the present invention as described above, the PIN 3 may be fixedly attached to the rear case 2 in various ways. The fixing connection mode includes but is not limited to adhesive connection, screw nut connection, internal and external thread connection, elastic deformation connection or any combination thereof. In addition, in a particularly preferred embodiment, the PIN 3 may be fixedly attached to the rear housing 2 by means of an insert molding process to form an insert molding. In this case, the PIN 3 and the rear housing 2 can be firmly and firmly fixedly connected, and the fixed connection can also play a good role in isolation in the case that the cavity 4 needs to be sealed.

In addition, in the case where the rear case 2 is made of metal, electrical insulation is also required between the PIN 3 and the rear case 2.

In the camera device according to the present invention, the manner of fixedly connecting the rear end 8b of the spring piece to the PIN front end 3a is not particularly limited as long as the rear end 8b of the spring piece and the PIN front end 3a can be electrically connected to each other stably. Here, the fixing connection means includes, but is not limited to, a conductive adhesive connection, a welding connection, a threaded bushing connection, a binding connection, or any combination thereof.

In addition, the PIN rear end 3b can be connected with an automobile end connector in a manner known to those skilled in the art, so that the optical sensor is electrically connected with the automobile end connector.

In the camera device of the present invention as described above, the mutual positions of the two or more PIN PINs 3, the mutual positions of the two or more through holes 9, the mutual positions of the PIN PINs 3 and the through holes 9, the shape and length of the conductive elastic piece 8, and the lengths of the PIN front end 3a and the PIN rear end 3b are not particularly limited. The technical parameters matched with each other can be completely selected by those skilled in the art according to the teaching of the utility model, so as to achieve the purpose of the utility model.

In addition, the respective numbers of the PIN PINs 3, the conductive dome 8, the perforations 9 comprised by the sensor board 6 and the through holes comprised by the rear shell 2 are independent from each other, i.e. they are not necessarily equal, however, it is preferred that the respective numbers are equal. The number may be 2 as illustrated in fig. 1 or 4 as illustrated in fig. 6 according to actual needs. Of course, the number may also be a number of 3, 5, 6, 7, 8 or more, respectively.

Fig. 6 illustrates a spring-through-plate floating connector of the present invention. For the sake of clarity, only the sensor board 6, the back shell 2, the PIN 3 and the conductive dome 8 are shown in fig. 6. When the spring plate-through-plate floating type connector is used in the camera device, the sensor plate 6 is connected with the conductive spring plate 8 fixedly connected with the PIN PIN 3 through the through hole 9 contained in the sensor plate. In such a connection manner, due to the elastic modulus of the conductive elastic sheet 8, the sensor board 6 can move and/or rotate in multiple directions in directions X, Y and Z, so that the problem of displacement tolerance of circuit board assembly in the camera device can be effectively solved.
