Description

Technical Field

[0001] This utility model relates to the field of camera modules, specifically to a camera that can be side-welded. Background Technology

[0002] Cameras have a wide range of applications. Taking mobile phone cameras as an example, current mobile phone cameras include a substrate, lens, motor, bracket, and other structures. During assembly, the substrate and motor need to be soldered together. To facilitate soldering, copper soldering terminals need to be provided at the bottom of the motor opposite the substrate. To prevent subsequent installed structures from obstructing the soldering area and to prevent the heat from soldering from damaging other structures, the motor needs to be soldered to the substrate first before installing other structures. However, because the soldering position is located between the substrate and the motor, soldering is relatively inconvenient, and the installation efficiency of the camera is also affected.

[0003] Currently, there exists a camera module and electronic device as disclosed in application number CN202122015802.8, wherein the camera module includes a first substrate, the first substrate is stacked on a second substrate, the outer surface of the stacked first substrate is provided with a first welding surface, the outer surface of the stacked second substrate is provided with a second welding surface, and the first welding surface and the second welding surface are connected by welding to connect the first substrate and the second substrate.

[0004] In the aforementioned camera module, because the first and second welding surfaces are not obstructed, the first and second substrates can be connected by locally heating the first and second welding surfaces during welding. Although the aforementioned patent provides technical inspiration for setting the welding surfaces on the outer surface to facilitate welding, when applied to welding a motor to a substrate, the first and second welding surfaces are perpendicular to each other, and welding can only be performed in a vertical position. Therefore, the contact area between the first and second welding surfaces is small, resulting in defects such as small welding area and low strength. Consequently, this welding method cannot be applied to welding periscope motors to substrates where high reliability is required. Utility Model Content

[0005] The present invention aims to provide a camera that can be welded from the side to solve the problems of small welding area and low strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a camera that can be side-welded, comprising a substrate and a motor, wherein the motor sidewall is provided with a welding end, the substrate is connected to an extension plate, and the extension plate is provided with a solder pad opposite to the welding end, the solder pad being electrically connected to the substrate.

[0007] The beneficial effects of this plan are: 1. In this solution, the welding end is located on the side wall of the motor. During installation, the welding pad is welded to the welding end. Compared with the two welding surfaces that are distributed in an L-shape in the prior art, the welding pad in this solution is directly opposite the welding end. Therefore, the contact area between the welding pad and the welding end in this solution is larger. When the welding pad and the welding end are welded, the area of ​​the welding part is larger, the welding strength is greater, and the welding reliability is higher.

[0008] 2. The solder pads are connected to the base plate via an extension plate. Since the soldering end is located on the side of the motor, the heat generated by the soldering can be dissipated quickly with minimal impact on other components. At the same time, the solder pads on the extension plate are opposite to the soldering end. Therefore, in this solution, the part of the extension plate near the motor is located on the side of the motor. After the motor is installed, the extension plate can limit the motor, thereby improving the motor installation strength.

[0009] Furthermore, the pads and the side of the soldering end facing the pads are parallel.

[0010] The beneficial effects of this solution are: parallelism allows for a larger welding area between the pad and the welding end, resulting in greater welding strength and higher reliability.

[0011] Furthermore, the cross-section of the pad along the height direction is C-shaped.

[0012] The beneficial effects of this solution are as follows: In addition to the side facing the welding end, the inner periphery of the C-shaped pad can also increase the available welding surface, thereby further increasing the welding area and improving the welding strength.

[0013] Furthermore, a welding plate is provided on the side of the motor, the welding plate is provided with a receiving groove, the welding pad is located in the receiving groove and the side wall of the welding pad is attached to the side wall of the receiving groove, one side wall of the welding plate is attached to the welding end, and the welding plate is provided with a conductive part that connects the welding pad and the welding end.

[0014] The beneficial effects of this solution are as follows: In this solution, the pads are fixed to the welding ends by welding the welding plate. Compared with welding the pads directly to the welding ends, the pads in this solution are located in the receiving groove. In this case, the sidewalls of the pads that are in contact with the receiving groove are welded to the receiving groove, thus resulting in greater welding strength between the pads and the welding plate. Furthermore, when multiple welding ends and pads are provided, multiple receiving grooves are provided on the welding plate, allowing the welding plate to be fixed to multiple pads and multiple welding ends simultaneously, connecting multiple pads and welding ends into a single unit. No single pad or welding end will be subjected to force independently, further reducing the risk of the pads detaching from the motor due to damage to the welding area.

[0015] Furthermore, the cross-section of the receiving groove along the height direction is also C-shaped.

[0016] The beneficial effects of this solution are: the inner peripheral sidewall of the pad can also be attached to and welded to the sidewall of the receiving groove, further increasing the welding area between the pad and the receiving groove and improving the welding strength.

[0017] Furthermore, the welding plate is provided with a shielding part, which is located on the side of the receiving groove away from the welding end.

[0018] The beneficial effects of this solution are as follows: After the welding plate in this solution is installed, the shielding part can shield the welding pad and the welding end, preventing external dust or other objects from contacting the welding part between the welding pad and the welding end, which would cause damage to the welding part.

[0019] Furthermore, at least one of the sides of the pad facing the welding end and the side away from the welding end is provided with a limiting step, which abuts against the side wall of the receiving groove.

[0020] The beneficial effects of this solution are: the limiting step can limit the installation of the welding plate, ensuring that the conductive part is located between the welding pad and the welding end.

[0021] Furthermore, the sidewall of the pad is provided with a groove, and the limiting step is formed by the sidewall of the groove.

[0022] The beneficial effects of this solution are: the settling tank in this solution can accommodate the side wall of the receiving tank, thereby preventing the side wall of the receiving tank from protruding too much outward, which facilitates the installation of the welding plate and its contact with the welding end.

[0023] Furthermore, there are two extension plates, which are located on both sides of the motor, and each side of the motor has a welding end that is opposite to the two extension plates.

[0024] The beneficial effects of this solution are: the connection strength between the substrate and the motor is further increased. At the same time, the two extension plates can limit the motor from both sides, further improving the connection strength between the substrate and the motor.

[0025] Furthermore, an adhesive layer is provided between the extension plate and the motor, the adhesive layer being used to fix the extension plate and the motor.

[0026] The advantages of this solution are as follows: First, the extension plate is fixed to the motor via an adhesive layer, preventing the motor from tilting relative to the substrate before soldering and improving the installation accuracy of both. Second, since the extension plate and motor are fixed together via the adhesive layer, the motor is also fixed to the substrate via the extension plate. Even if the motor is under stress, the extension plate can still support the motor, thereby preventing damage to the solder joint between the solder pad and the soldering end.

[0029] Example The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a side-welded camera includes a substrate 1 and a motor 2. The substrate 1 is located below the motor 2. In this embodiment, the substrate 1 uses a conventional rigid circuit board, and the motor 2 is a periscope motor 2. The front sidewall of the motor 2 is provided with multiple welding ends 21, which are distributed sequentially from left to right. The rear sidewall of the motor 2 is also provided with multiple welding ends 21, which are also distributed sequentially from left to right. Specifically, in this embodiment, the welding ends 21 are made of copper. Based on the existing periscope motor 2 structure, the welding ends 21 are moved from the bottom of the motor 2 to the front and rear sidewalls of the motor 2. Apart from this, the other structures of the motor 2 are the same as those in the prior art, and will not be described in detail in this embodiment.

[0030] The substrate 1 has extension plates 3 on both the front and rear sides. In this embodiment, the extension plates 3 are inverted L-shaped and integrally formed with the substrate 1. This embodiment is described using the front extension plate 3 and the welding end 21 as an example: multiple pads 31 are fixed on the extension plate 3. The pads 31 correspond one-to-one with the welding end 21 on the front side. In actual implementation, the pads 31 and the extension plate 3 can be integrally formed, and conductive material can be used as the material of the extension plate 3 and the pads 31. Alternatively, only the pads 31 can be made of conductive material, and wires can be fixed on the extension plate 3 to realize the electrical connection between the pads 31 and the substrate 1.

[0031] The pad 31 is parallel to the welding end 21. The cross-section of the pad 31 along the height direction of the camera is a C-shape with the opening facing upwards. The front and rear side walls of the pad 31 are provided with C-shaped grooves. The side walls of the grooves extending along the thickness direction of the extension plate 3 form a limiting step 32. The extension plate 3 is provided with a welding plate 4. The side of the welding plate 4 facing the welding end 21 is provided with multiple receiving grooves 43. The receiving grooves 43 correspond one-to-one with the pad 31. The vertical cross-section of the receiving grooves 43 is a C-shape with the opening facing downwards. The pad 31 is located in the receiving groove 43, and the left and right side walls and the inner peripheral side walls of the pad 31 are in contact with the side walls of the receiving groove 43. The arc-shaped side of the outer periphery of the pad 31 abuts against the limiting step 32 to limit the welding plate 4. In this embodiment, after the motor 2 is installed between the two extension plates 3, the side wall of the welding plate 4 facing the welding end 21 is in contact with the side wall of the welding end 21. The side wall of the welding plate 4 located between the receiving groove 43 and the welding end 21 is a conductive part 42 made of conductive material, used to achieve electrical connection between the solder pad 31 and the welding end 21. In this embodiment, the projection of the conductive part 42 to the right completely covers the welding end 21, increasing the welding strength. A shielding part 41 is formed on the left side of the welding plate 4, allowing the motor 2 to shield the welding part after installation, preventing dust and other contaminants from entering and causing damage.

[0032] An adhesive layer is provided between the lower part of the extension plate 3 and the motor 2. The two sides of the adhesive layer are respectively glued and fixed to the extension plate 3 and the motor 2 to fix the extension plate 3 and the motor 2.

[0033] In this embodiment, during camera installation, the welding plate 4 is first installed on the extension plate 3, and then the motor 2 is installed between the two extension plates 3. The extension plates 3 and the motor 2 are then fixed together with an adhesive layer to improve the installation strength of the motor 2. Then, laser welding is used to weld the pad 31 to the side wall of the receiving groove 43 and the conductive part 42 to the welding end 21, thus completing the electrical connection between the motor 2 and the substrate 1.
