Description

Technical Field

[0001] This application belongs to the technical field of imaging devices, and particularly relates to a camera motor and an electronic device. Background Art

[0002] Currently, during the use of a camera motor, the moving parts of the motor may rub against and impact the fixed parts, generating debris that affects the quality of the camera. Therefore, before leaving the factory, a vibration test is required to determine the generation of debris. Specifically, usually after the motor undergoes a vibration test, the product is disassembled to confirm whether the upper and lower contact surfaces and the side contact surfaces are impacted and rubbed to generate debris, and a comparison and determination are made on the degree of defect at the impact site and the amount of debris.

[0003] For related camera motors, due to the continuous increase in the pixel count of the camera, the weight of the lens must also increase. In the structural design of related technologies, when subjected to impact, the force at the impact position will be greater, the probability of chipping will be higher, and the probability of generating black spots in the camera image will be higher, thus affecting the user experience. Summary of the Invention

[0004] This application aims to provide a camera motor and an electronic device. By setting an anti-collision platform and moving the injection port of the base away from the anti-collision platform, the debris generated by the irregular filaments at the injection port position during impact or friction is avoided, greatly improving the imaging quality.

[0005] To achieve the above object, the camera motor provided in the embodiment of the first aspect of this application includes: a housing; a base detachably connected to the housing, the base is provided with a light-transmitting hole, and an anti-collision platform is provided on the side of the base facing the housing, and the anti-collision platform protrudes from the surface of the base; a motor main body disposed in the accommodation cavity formed by the connection of the base and the housing; an injection port disposed on the base, and the injection port and the anti-collision platform are misaligned on the base.

[0006] According to the embodiment of the camera motor provided by this application, it mainly includes a detachably connected base and housing, and a motor main body located in the accommodation cavity formed after the two are connected. Under the action of the motor main body, the position of the lens can be adjusted. Among them, after the camera motor is impacted, the motor main body will collide with the base. Generally, the base is made of plastic. Therefore, when a collision occurs, the motor main body will collide with the anti-collision platform provided on the base, and thus debris will be generated. The generated debris is likely to fall to the position of the light-transmitting hole and generate a black shadow during shooting, thus affecting the imaging effect. By moving the injection port that is likely to generate debris during collision away from the anti-collision platform, that is, the position of the injection port on the base does not coincide with the position of the anti-collision platform on the base, that is, they are misaligned. When a collision occurs, the injection port is transferred to a non-impact surface, which will greatly reduce the debris generated by the irregular filaments at the injection port position during impact or friction.

[0007] Specifically, the base and the housing are detachably connected for easy installation. When the housing is connected to the base, a receiving cavity is formed inside. The motor body is disposed in the receiving cavity. The base is provided with a light-transmitting hole adapted to the lens, so that light can normally pass through the lens and enter the sensor, thereby realizing imaging. When the camera motor is violently impacted by an external force, the motor body will move correspondingly due to inertia. Since the base is provided with a collision-preventing platform protruding inward, that is, the collision-preventing platform is disposed on the side of the base facing the housing, the motor body will collide with the collision-preventing platform during the impact, reducing the collision area, which is also beneficial to reducing the generation of debris and the appearance of black shadows during shooting.

[0008] It should be emphasized that on the basis of setting the collision-preventing platform in this application, the injection port of the base is moved away from the collision-preventing platform to avoid debris generated by irregular filaments at the injection port position during impact or friction, greatly improving the imaging quality.

[0009] The electronic device provided by the embodiment of the second aspect of this application includes: a housing; any one of the camera motors as described in the above first aspect embodiment, disposed on the housing.

[0010] According to the embodiment of the electronic device provided by this application, it mainly includes a housing and a camera motor disposed on the housing. The camera motor can be disposed on the front side of the housing to drive the lens for photographing an object in front, or can be disposed on the back side of the housing to drive the lens for photographing an object behind, and even can be connected to the housing in a movable connection manner.

[0011] Among them, the housing can be the middle frame, front panel or rear cover plate of the electronic device, etc.

[0012] In addition, since the electronic device includes the camera motor of any of the above embodiments, it has the beneficial effects of any of the above embodiments.

[0013] Among them, the electronic device includes devices with shooting requirements such as mobile phones, tablets, cameras, video cameras, laptops, etc.

[0014] The additional aspects and advantages of this application will become obvious in the following description part, or be learned through the practice of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The electronic device provided in the embodiment of the present application can be a device with a shooting requirement such as a mobile phone, a tablet, a camera, a video camera, a notebook, etc.

[0028] The following refers to Figures 1 to 7 Describe a camera motor and an electronic device provided according to an embodiment of the present application.

[0029] As Figure 1 and Figure 2 As shown, an embodiment of the present application provides a camera motor 100, including: a housing 102; a base 104 detachably connected to the housing 102, a light-transmitting hole 1042 on the base 104, an anti-collision platform 1044 provided on the side of the base 104 facing the housing 102, and the anti-collision platform 1044 protruding from the surface of the base 104; a motor main body 106 provided in the accommodation cavity formed by the connection of the base 104 and the housing 102; an injection port 1046 provided on the base 104, and the injection port 1046 is misaligned with the anti-collision platform 1044 on the base 104.

[0030] According to the embodiment of the camera motor 100 provided by the present application, it mainly includes a detachable base 104 and a housing 102, and a motor main body 106 located in the accommodation cavity formed after the two are connected. Under the action of the motor main body 106, the position of the lens can be adjusted. Among them, after the camera motor 100 is impacted, the motor main body 106 will collide with the base 104. Generally, the base 104 is made of plastic material. Therefore, when a collision occurs, the motor main body 106 will collide with the anti-collision platform 1044 provided on the base 104, and thus debris will be generated. The generated debris is very likely to fall to the position of the light-transmitting hole 1042, and black shadows will be generated during shooting, thus affecting the imaging effect. In the present application, by moving the injection port 1046 that is likely to generate debris during a collision away from the anti-collision platform 1044, that is, the position of the injection port 1046 on the base 104 does not coincide with the position of the anti-collision platform 1044 on the base 104. When a collision occurs, the injection port 1046 is transferred to a non-impact surface, which will greatly reduce the debris generated by the irregular filaments at the position of the injection port 1046 during impact or friction.

[0031] Specifically, as Figure 3As shown, the base 104 and the housing 102 are detachably connected for easy installation. When the housing 102 is connected to the base 104, a receiving cavity is formed inside. The motor main body 106 is disposed in the receiving cavity. The base 104 is provided with a light-transmitting hole 1042 that is adapted to the lens, so that light can normally pass through the lens and enter the sensor, thereby achieving imaging. When the camera motor 100 is violently impacted by an external force, the motor main body 106 will move correspondingly due to inertia. Since the base 104 is provided with a collision prevention platform 1044 that protrudes inward, that is, the collision prevention platform 1044 is disposed on the side of the base 104 facing the housing 102. During the impact, the motor main body 106 will collide with the collision prevention platform 1044, reducing the collision area and also facilitating the reduction of debris generation and the appearance of black shadows during shooting.

[0032] It should be emphasized that on the basis of setting the collision prevention platform 1044, the injection port 1046 of the base 104 is moved away from the collision prevention platform 1044 to avoid debris generated by irregular filaments at the position of the injection port 1046 during impact or friction, greatly improving the imaging quality.

[0033] Among them, the detachable connection between the base 104 and the housing 102 can be a magnetic connection or a snap connection.

[0034] Among them, the housing 102 and the base 104 can be in the shape of a cube or a cuboid, or generally in the shape of a cube or a cuboid, as long as there is space for setting the collision prevention platform 1044 on the base 104 on the basis of meeting the size of the light-transmitting hole 1042.

[0035] Among them, the shape of the light-transmitting opening can be adapted to the lens for light to pass through.

[0036] For the collision prevention platform 1044, the end facing the housing 102, that is, the end that collides with the motor main body 106, can be set as a flat surface to reduce the pressure during collision and reduce the generation of debris.

[0037] Furthermore, as Figure 5 shown, the camera motor 100 further includes: a first groove 1082, disposed on the base 104, the collision prevention platform 1044 is disposed in the first groove 1082, and the first groove 1082 is recessed from the surface of the side of the base 104 facing the housing 102 in a direction away from the housing 102.

[0038] By providing a first groove 1082 on the base 104, the first groove 1082 is provided on the side of the base 104 facing the housing 102 and extends outward to form a groove shape. At this time, by setting the anti-collision platform 1044 into the first groove 1082, on the one hand, the size of the anti-collision platform 1044 can be reduced, and on the other hand, under the action of the first groove 1082, when a collision occurs, the debris generated on the anti-collision platform 1044 will fall into the first groove 1082, which can effectively reduce the possibility of falling onto the light-transmitting hole 1042 and greatly reduce the possibility of black shadows occurring during shooting.

[0039] It should be noted that, as Figure 4 shown, the shape of the anti-collision platform 1044 can be the same as the shape of the first groove 1082, and there can also be unilateral or bilateral gaps 1070, as long as the debris can fall into the first groove 1082.

[0040] Furthermore, there is a gap between at least one side wall of the anti-collision platform 1044 located in each first groove 1082 and the inner wall of the first groove 1082.

[0041] By restricting the position of the anti-collision platform 1044 in the first groove 1082, that is, restricting that the side wall of the anti-collision platform 1044 in the first groove 1082 does not contact the inner wall of the first groove 1082, that is, there is a gap between the two, so as to provide a collection path for the falling debris and improve the collection effect.

[0042] Specifically, the cross-section of the anti-collision platform 1044 is rectangular.

[0043] In a specific embodiment, one side wall of the anti-collision platform 1044 is not adjacent to the inner wall of the first groove 1082, but is spaced apart.

[0044] In another specific embodiment, the two opposite side walls of the anti-collision platform 1044 do not contact the inner wall of the first groove 1082. Further, the two side walls are two circumferential side walls, or the two side walls are two radial side walls.

[0045] In another specific embodiment, three side walls of the anti-collision platform 1044 do not contact the inner wall of the first groove 1082.

[0046] Furthermore, it further includes: a dust sticking material 110, which is filled in the first groove 1082.

[0047] By filling the dust sticking material 110 in the first groove 1082, it can effectively adsorb dust and debris, thereby improving the adsorption ability of the debris, adsorbing the debris into the first groove 1082 as much as possible, and reducing the influence on the viewfinder of the inner lens.

[0048] The dust-binding material 110 may be in a colloid form, such as glue, and materials having properties of resistance to high and low temperature environments, high temperature and high humidity environments, and water washing may be selected.

[0049] Furthermore, if Figure 5 As shown, it also includes: a second groove 1084, which is arranged on the base 104, and the shape of the second groove 1084 is adapted to the shape of the light-transmitting hole 1042. In the radial direction of the light-transmitting hole 1042, the second groove 1084 is arranged on the inner side of the anti-collision platform 1044.

[0050] By setting a second groove 1084 on the base 104 that is adapted to the shape of the light-transmitting hole 1042, under the action of the second groove 1084, after the anti-collision platform 1044 collides, the debris will fall into the second groove 1084 during the process of moving toward the light-transmitting hole 1042, thereby reducing the probability of black shadows appearing and improving the shooting quality.

[0051] The second groove 1084 is disposed close to the light-transmitting hole 1042 , which makes it easier to collect debris moving toward the light-transmitting hole 1042 .

[0052] Furthermore, if Figure 6 As shown, it also includes: dust-binding material 110 filled in the second groove 1084.

[0053] By filling the second groove 1084 with dust-adhesive material 110, dust and debris can be effectively adsorbed, thereby improving the adsorption capacity of debris, adsorbing the debris into the second groove 1084 as much as possible, and reducing the impact on the framing of the inner lens.

[0054] The dust-binding material 110 may be in a colloid form, such as glue, and materials having properties of resistance to high and low temperature environments, high temperature and high humidity environments, and water washing may be selected.

[0055] Furthermore, the motor body 106 specifically includes: a lens carrier 1062, on which at least one lens is provided; a magnet 1064, which is wound around the outside of the lens carrier 1062; a spring 1066, which is provided at both ends of the lens carrier 1062; a coil 1068, which is provided on the lens carrier 1062, and the coil 1068 cooperates with the magnet 1064 to drive the lens carrier 1062 to move; wherein, there is a gap 1070 between the lens carrier 1062 and the base 104.

[0056] The motor body 106 mainly includes a lens carrier 1062, a magnet 1064, a shrapnel 1066 and a coil 1068. Among them, one or more lenses are provided on the lens carrier 1062, and the positions of the lenses correspond to the positions of the light-transmitting holes 1042 on the base 104, so that light can pass through the lenses and then enter the sensor through the light-transmitting holes 1042, thereby realizing imaging. In addition, by winding a magnet 1064 around the lens carrier 1062 and providing a coil 1068 on the lens carrier 1062, the lens carrier 1062 can be driven to move under the cooperation of the coil 1068 and the magnet 1064, thereby realizing the driving of the lens. It can be understood that after the coil 1068 is energized, a magnetic field will be formed, and the magnet 1064 itself also has a certain magnetic field, which can be realized through the interaction force of the two magnetic fields. Further, by adjusting the current direction of the coil 1068, the magnetic poles of the magnetic field will also change, so as to realize the driving of the lens carrier 1062 under the cooperation at this time.

[0057] It should be added that by respectively arranging shrapnels 1066 at both ends of the lens carrier 1062, a certain buffering effect can be achieved, so as to reduce the possibility of direct collision when being impacted. At the same time, under the action of the shrapnel 1066, due to buffering and attenuating the impact force, the debris generated by the anti-collision platform 1044 can also be reduced.

[0058] Among them, in the normal state, there is a gap 1070 between the lens carrier 1062 and the base 104, so as to provide a certain margin for the movement of the lens carrier 1062.

[0059] Further, a carrier collision platform 1063 is provided on the lens carrier 1062, and the position of the carrier collision platform 1063 corresponds to the position of the anti-collision platform 1044 one by one. The lens carrier 1062 moves towards the base 104, and the carrier collision platform 1063 abuts against the anti-collision platform 1044.

[0060] By providing a carrier collision platform 1063 on the lens carrier 1062 corresponding to the position of the anti-collision platform 1044, the impact on the lenses in the lens carrier 1062 can be reduced. That is, under the action of the carrier collision platform 1063, when being impacted, a collision will occur between the carrier collision platform 1063 and the anti-collision platform 1044, thereby realizing

[0061] Further, the number of the anti-collision platforms 1044 is multiple, and the multiple anti-collision platforms 1044 are evenly arranged on the base 104 around the axis of the light-transmitting hole 1042.

[0062] By selecting multiple anti-collision platforms 1044 and evenly arranging the multiple anti-collision platforms 1044 on the base 104, when a collision occurs, the force on the anti-collision platforms 1044 can be made more uniform, reducing the possibility that some anti-collision platforms 1044 are damaged too much and causing tilting.

[0063] In a specific embodiment, the anti-collision platforms 1044 can be selected as four, which are respectively arranged at the four corners of the rectangular base 104.

[0064] This application also proposes a structural design solution for reducing the occurrence of black spots in the camera image in a specific embodiment. The anti-collision platforms 1044 of the motor are retained and optimized. Due to limited space, the position area of the anti-collision platforms 1044 can be appropriately reduced, and the minimum reduced size is length × width = 0.15 mm × 0.15 mm. Move the injection port during the production process out of the anti-collision platforms 1044 to the non-impact surface to avoid debris generated by the irregular filaments at the injection port position during impact or friction. At the same time, a plurality of grooves are designed on the inner base 104 of the motor. Based on the utilization of the motor space, there are multiple choices for the groove positions. Among them, the two preferred groove positions are: ① around the position where debris is generated by the impact and friction of the motor (i.e., the first groove 1082), and the debris generated at the impact position of the motor can be immediately intercepted; ② around the inner circumference of the motor base 104 (i.e., the second groove 1084) to prevent the debris inside the motor from flowing out of the motor. Add dust-catching glue (i.e., the dust-catching material 110) to the grooves. This glue has the function of effectively adsorbing and capturing dust, and has the characteristics of resisting high and low temperature environments, high temperature and high humidity environments, and water washing. There is a sufficient gap 1070 between the carrier of the motor and the base 104 during the impact process and the grooves. The minimum value of the gap 1070 is 0.05 mm to ensure that the carrier and the base 104 will not be adhered by the dust-catching glue during the impact process after adding the dust-catching glue.

[0065] Among them, through the structural solution of the above specific embodiment, the generation of black spots in the camera can be reduced, the user experience can be improved, and the product strength can be increased; at the same time, it also has the advantages of low technical difficulty and strong manufacturability. In addition, the application range of this solution is wide, not limited to the shrapnel 1066 motor, and is applicable to piezoelectric ceramic motors or ball motors.

[0066] As Figure 7 shown, the electronic device 200 provided by the embodiment of the second aspect of this application includes: a housing 202; any camera motor 100 as in the embodiment of the first aspect above, which is arranged on the housing 202.

[0067] According to the embodiment of the electronic device 200 provided by this application, it mainly includes a housing 202 and a camera motor 100 arranged on the housing 202. The camera motor 100 can be arranged on the front side of the housing 202 to photograph the object in front, or can be arranged on the back side of the housing 202 to photograph the object behind, and even can be connected to the housing 202 in a movable connection manner to achieve random shooting.

[0068] In addition, since the electronic device 200 includes the camera motor 100 of any of the above embodiments, it has the beneficial effects of any of the above embodiments.

[0069] According to the embodiments of the camera motor and the electronic device of the present application, by moving the injection port of the base away from the anti-collision platform on the basis of setting the anti-collision platform, the debris generated by the irregular filaments at the injection port position during impact or friction is avoided, greatly improving the imaging quality.
