[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not intended to limit the present application.

[0029] Referring to Figure 1 and Figure 2 The embodiment of the present application provides a camera, which comprises a shell 1, a lens 2 and a conductive body, the shell 1 is provided with a mounting hole 11; the lens 2 is at least partially mounted in the mounting hole 11; the conductive part 3 is arranged in the mounting hole 11 and respectively contacts the lens 2 and the shell 1.

[0030] In actual application, the lens 2 is installed in the part of the mounting hole 11 to be exposed, the insulation layer is broken to facilitate static conduction, the conductive part 3 is installed between the lens 2 and the hole wall of the mounting hole 11 and respectively contacts the exposed part of the lens 2 and the hole wall of the mounting hole 11, which is convenient for the conductive part 3 to conduct static electricity between the lens 2 and the shell 1, and in the static discharge test, the static electricity is guided to the shell 1.

[0031] It should be noted that the lens 2 is usually referred to as a special treatment on the surface or edge of the lens 2 during the manufacturing or processing of the lens 2, so that part of the area exposes the white color of the underlying material. The conductive part 3 refers to a component or element with good conductivity, which mainly functions to transmit current to realize the conduction of the circuit, such as metal structure.

[0032] Compared with the prior art, the lens 2 and the shell 1 are connected through the conductive part 3, and in the electrostatic discharge test, the current can be guided from the lens 2 to the shell 1 through the conductive part 3, avoiding the current being guided to the circuit board, optimizing the electrostatic conduction route, ensuring the safety of the camera module function, and at the same time, this way does not need to point the conductive glue, simplifying the module production process, controlling the production cost and realizing the platformization.

[0033] Referring to Figure 3 , the conductive part 3 is elastically abutted between the lens 2 and the mounting hole 11. In actual application, the conductive part 3 is abutted with the lens 2 and the mounting hole 11 respectively, which can improve the connection stability of the conductive part 3 and avoid the shaking of the conductive part 3. In the assembly process, the conductive part 3 can be used as a positioning and supporting component to help the lens 2 be more accurately installed in the shell 1, improving the assembly precision.

[0034] Referring to Figure 3 , the conductive part 3 includes a fixed part 31 and an elastic part 32, the elastic part 32 is sleeved on the outer periphery of the lens 2 and elastically abuts with the lens 2, the fixed part 31 is connected with the elastic part 32, and the fixed part 31 is fixed to the shell 1.

[0035] In actual application, the elastic part 32 is arranged in the mounting hole 11 and sleeved on the outer periphery of the exposed part of the lens 2, and the elastic part 32 elastically abuts with the lens 2 to play a role of buffering and shock absorption. For example, bumps during vehicle driving, vibrations during machine operation, etc. The elastic abutment can effectively absorb and dissipate these impact forces, avoiding component damage, fatigue failure and other problems caused by rigid contact, prolonging the service life of the equipment; At the same time, the elastic abutment can make up for the manufacturing tolerance due to the limitation of process and equipment. The fixed part 31 is mainly used to fix the conductive part 3 and the shell 1 together, and the fixed part 31 and the shell 1 can be fixed outside the mounting hole 11 to avoid affecting the abutment of the elastic part 32 and the lens 2.

[0036] It should be noted that the elastic part 32 is a part or structure in an object that has elastic properties, which can deform when subjected to external force, and can recover to its original shape and size when the external force is removed.

[0037] Referring to Figure 4, the elastic part 32 includes a sleeve ring 321 and an abutting spring 322, the sleeve ring 321 is annular and sleeved on the outer periphery of the lens 2, one end of the abutting spring 322 is integrally connected with the sleeve ring 321, and the abutting spring 322 extends to the inner side of the sleeve ring 321 and elastically abuts with the lens 2. In actual application, the sleeve ring 321 can be sleeved on the outer periphery of the exposed part of the lens 2 first, and then the lens 2 is inserted into the mounting hole 11, at this time, the exposed part of the lens 2 abuts with the abutting spring 322, the sleeve ring 321 mainly plays a role of fixing and supporting the lens 2, and the abutting spring 322 mainly plays a role of realizing electrostatic conduction with the lens 2, so as to ensure that the current on the lens 2 can be guided to the conductive part 3, and then guided to the shell 1. The abutting spring 322 and the sleeve ring 321 can adopt an integrally formed structure, which is beneficial to modular production and improves production efficiency.

[0038] It should be noted that the sleeve ring 321 can be installed in the mounting hole 11 first, and then the exposed part of the lens 2 is inserted into the sleeve ring 321.

[0039] Specifically, referring to Figure 5 , the abutting spring 322 includes a first spring 3221 and a second spring 3222, a first end of the first spring 3221 is integrally connected to the sleeve ring 321, a second end of the first spring 3221 extends obliquely to the inner side of the sleeve ring 321, a first end of the second spring 3222 is integrally connected to the second end of the first spring 3221, and a second end of the second spring 3222 extends obliquely to the outer side of the sleeve ring 321. There is a circular arc transition connection structure between the first end of the second spring 3222 and the second end of the first spring 3221.

[0040] The abutting spring 322 first extends obliquely to the inner side of the sleeve ring 321, so that a certain interval is formed between the abutting spring 322 and the sleeve ring 321, so as to ensure that the abutting spring 322 has a certain elastic deformation space, and then extends obliquely to the outer side of the sleeve ring 321, so that the connection between the first spring 3221 and the second spring 3222 forms a circular arc structure. The circular arc structure has soft and smooth lines, which can protect the lens 2 from being scratched and prevent affecting the refraction and focusing of light.

[0041] Referring again to Figure 5 , the abutting spring 322 is provided in plurality, and the plurality of abutting springs 322 are circumferentially spaced apart along the inner side of the sleeve ring 321. In actual application, the plurality of abutting springs 322 can be uniformly and spaced apart on the sleeve ring 321, and the plurality of abutting springs 322 can be arranged around the lens 2 to apply uniform radial clamping force, which helps to ensure the stability of the position of the lens 2 in the radial direction and prevent displacement or shaking, thereby ensuring the reliability and accuracy of mechanical connection.

[0042] Referring again to Figure 4The camera further comprises a fixing member 4, the shell 1 is provided with a positioning groove 12, the fixing part 31 is inserted into the positioning groove 12, the fixing part 31 is provided with a first fixing hole 311, the shell 1 is provided with a second fixing hole 13 in the positioning groove 12, and the fixing member 4 is sequentially inserted into the first fixing hole 311 and the second fixing hole 13, so as to fix the fixing part 31 and the shell 1.

[0043] In actual application, the shell 1 is provided with the positioning groove 12 which is communicated with the mounting hole 11, and the fixing part 31 is inserted into the positioning groove 12, so that the positioning groove 12 provides an accurate mounting position for the fixing part 31, thereby improving the assembly efficiency and the consistency of product quality; and the existence of the positioning groove 12 can limit the movement of the fixing part 31 in a specific direction, thereby reducing the risk of loosening or falling off of the fixing part 31 due to external forces such as vibration and impact.

[0044] Meanwhile, the fixing part 31 is further provided with the first fixing hole 311, the shell 1 is provided with the second fixing hole 13, when the fixing part 31 is inserted into the positioning groove 12, the first fixing hole 311 and the second fixing hole 13 correspond to each other, and the fixing member 4 is inserted into the first fixing hole 311 and the second fixing hole 13 to be fixedly connected, so as to realize the fixed connection between the fixing part 31 and the shell 1. By adopting this structure, only one screw or bolt or other fixing member 4 is needed to be fixed after installation, so that the production process is convenient and the module production efficiency is improved.

[0045] It should be noted that the fixing member 4 can adopt a screw or a bolt structure.

[0046] Again referring to Figure 5 The sleeve ring 321 is provided with a cut groove 3211, and the cut groove 3211 is used to provide a deformation space for the abutting spring plate 322. Specifically, the sleeve ring 321 is provided with the cut groove 3211 at a position corresponding to the abutting spring plate 322, when the lens 2 is inserted into the sleeve ring 321, the lens 2 abuts against the abutting spring plate 322, so that the abutting spring plate 322 deforms away from the lens 2, at this time, the cut groove 3211 can provide a deformation space for the abutting spring plate 322, only in the case that there is enough deformation space, the abutting spring plate 322 can generate a stable and predictable elastic force within a certain abutting force range. When the deformation space is insufficient, the abutting spring plate 322 may reach the deformation limit too early, resulting in a sharp change in the elastic force, which cannot meet the requirement for stability of the elastic force in normal use, and affects the reliability of the connection with the lens 2. Moreover, the abutting spring plate 322 changes the space size by deformation, so that it can also adapt to lenses 2 of different sizes, thereby improving the practicality of the device.

[0047] It should be noted that the elastic part 32 can be formed by stamping, and the cutting groove 3211 is also formed by stamping. The stamping process generally does not require complex equipment and process, the mold cost is relatively low, and the material loss during stamping is relatively small. In addition, the production efficiency is high, so the processing cost of the product can be effectively reduced.

[0048] Referring again to Figure 5 , the sleeve 321 is open, and the open design makes the sleeve 321 not need to pass through the lens 2 completely like the closed sleeve 321 when installing. Only need to insert the lens 2 from the side opening, greatly reducing the difficulty and operation time of installation, and reducing the scratch of the surface layer of the lens 2. Due to the existence of the opening, the sleeve 321 can adjust the inner diameter size through appropriate elastic deformation, so as to better fit the lenses 2 of different sizes, expand its application range, and reduce the installation problems caused by slight differences in component size. And the open sleeve 321 does not need a complete annular structure to realize the connection function, so it can save some materials in the manufacturing process. This not only reduces the cost of raw materials, but also helps to reduce the weight of the sleeve 321 itself, thereby reducing the weight and cost of the entire camera module.

[0049] It can be understood that the size of the opening of the sleeve 321 should be less than half of the total size of the sleeve 321, so that the sleeve 321 has a good wrapping force on the lens 2.

[0050] Referring again to Figure 5 , the elastic part 32 further comprises a bending part 323, and the sleeve 321 is connected with the bending part 323 at the opening thereof. The bending part 323 bends away from the lens 2.

[0051] Specifically, the bending part 323 bends away from the lens 2, so that the connection between the sleeve 321 and the bending part 323 forms a circular arc structure. When the lens 2 is inserted into the sleeve 321, the circular arc structure can protect the lens 2 from being scratched. The bending part 323 can also abut with the hole wall of the mounting hole 11. In the case that the camera shakes or vibrates, the bending part 323 has a certain buffering capacity, so as to avoid the transmission of external force to the lens 2.

[0052] In one embodiment, the diameter of the sleeve 321 is between 10.5mm and 11.5mm, for example, the diameter of the sleeve 321 is 11.3mm. In this way, it can adapt to multiple lenses 2, and effectively realize the platform design.

[0053] In an embodiment, the maximum distance between the two abutting springs 322 is 9-10 mm, for example 9.95 mm, which can meet the size of most lenses 2 on the market, improving the practicality of the device; the abutting deformation of the abutting spring 322 and the lens 2 is 0.25-1.25 mm, for example 0.3 mm; this can ensure that the connection between the lens 2 and the abutting spring 322 is more stable, and the appropriate abutting deformation can keep the abutting spring 322 and the lens 2 in close contact, ensuring good electrical contact between the two, so that the static electricity generated on the lens 2 can be conducted to the housing 1 of the device through the abutting spring 322 in time, thereby effectively avoiding the harm of static electricity to the lens 2 and the internal circuit, improving the reliability and service life of the device. The abutting spring 322 can limit the displacement of the lens 2 in the radial direction through interference fit with the lens 2, ensuring that the lens 2 can be accurately installed to the predetermined position, ensuring the relative position accuracy between the optical axis of the optical system and other components, thereby improving the imaging quality and performance stability of the device.

[0054] At the same time, during the manufacturing process, there may be certain manufacturing tolerances in the size of the lens 2 and the abutting spring 322. By setting the abutting deformation, these tolerances can be compensated to some extent, allowing lenses 2 and springs produced by different batches or different manufacturers to be better matched for use. Even with some size deviation, appropriate abutting deformation can ensure that the connection and contact between the two meet the design requirements, improving the universality and interchangeability of the product, reducing production costs and inventory management difficulty.

[0055] Unlike the prior art, the embodiment of the application provides a camera, which includes a housing 1, a lens 2, and a conductive body. The housing 1 has a mounting hole 11. The lens 2 is at least partially installed in the mounting hole 11. The conductive part 3 is arranged in the mounting hole 11 and contacts the lens 2 and the housing 1, respectively. Compared with the prior art, the lens 2 and the housing 1 are connected through the conductive part 3, and in the electrostatic discharge test, the current can be guided from the lens 2 to the housing 1 through the conductive part 3, avoiding the current being guided to the circuit board, optimizing the electrostatic conduction route, and ensuring the safety of the camera module function. At the same time, by using this method, there is no need for point conductive glue, which simplifies the production process of the module, controls the production cost, and realizes platformization. The conductive part 3 is installed between the lens 2 and the hole wall of the mounting hole 11 and contacts the exposed part of the lens 2 and the hole wall of the mounting hole 11, respectively. This arrangement facilitates the conductive part 3 to conduct static electricity between the lens 2 and the housing 1, and in the electrostatic discharge test, the static electricity is guided to the housing 1, avoiding the static electricity being guided to the circuit board, and preventing the damage of the electrical elements on the circuit board.

[0056] The above description is only a specific implementation of the present application. It should be pointed out that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
