[0002] Currently, the motor assembly of a camera generally includes a coil and a magnetic member. The coil is fixed on a housing, and the magnetic member is fixed on a carrier of the camera. After the coil is powered on, it can drive the magnetic member to move, thereby driving the carrier and the camera to move, realizing functions such as zooming and anti-shaking of the camera.

[0003] However, the change in the position of the magnetic member leads to a change in the magnetic field position of the magnetic member. To reduce the mutual interference between other magnetic fields in the electronic device and the magnetic field of the magnetic member, a larger layout space needs to be provided for the motor assembly, thus affecting the overall layout of the electronic device. Summary of the Utility Model

[0046] The following will be combined with Figures 1 to 6 Describe a motor assembly 100, a camera device, and an electronic device according to an embodiment of this application.

[0047] In a first aspect, as Figure 1 and Figure 2 shown, an embodiment of this application provides a motor assembly 100, including: a housing 110; a slide rail 120 disposed on the housing 110, the slide rail 120 having electrical conductivity; a carrier 130 disposed on the slide rail 120 and located inside the housing 110, the carrier 130 being movable along the slide rail 120; a coil 140 disposed on the carrier 130 and electrically connected to the slide rail 120; a magnetic member 150 disposed on the housing 110, the magnetic member 150 being opposite to the coil 140.

[0048] In an embodiment of the present application, the motor assembly 100 includes a housing 110, a slide rail 120, a carrier 130, a coil 140, and a magnetic member 150. The slide rail 120 and the magnetic member 150 are disposed on the housing 110, the coil 140 is disposed on the carrier 130, the carrier 130 is slidably disposed on the slide rail 120. When the coil 140 is energized, a magnetic field is generated. The magnetic field of the coil 140 and the magnetic field of the magnetic member 150 interact with each other, causing the coil 140 to move, thereby driving the carrier 130 to move. Since the magnetic member 150 is disposed on the housing 110 and its position does not change, the position of the magnetic field of the magnetic member 150 is also fixed. Based on this, the required layout space of the motor assembly 100 can be reduced.

[0049] Moreover, the slide rail 120 has electrical conductivity, and the coil 140 and the slide rail 120 are electrically connected, that is, the coil 140 is powered through the slide rail 120, without adding an additional power supply line for the coil 140 on the carrier 130, thereby reducing the complexity of the structure of the motor assembly 100, making the structure of the motor assembly 100 simpler and easier to manufacture.

[0050] Wherein, the carrier 130 is used to fix the camera to drive the camera to move.

[0051] In the present application, by setting the slide rail 120 to a conductive material, the coil 140 can be fixed on the carrier 130, so that the coil 140 can move together with the carrier 130. Thus, the magnetic member 150 can be fixed on the housing 110. For the fixed magnetic member 150, its magnetic field is also fixed, reducing the possibility of the magnetic field of the magnetic member 150 being interfered, thereby enhancing the anti-magnetic interference ability of the motor assembly 100.

[0052] Wherein, the material of the slide rail 120 can be copper, gold, silver, or an alloy of the above three.

[0053] Such as Figure 2 、 Figure 3 and Figure 4 shown, as a possible implementation manner, it further includes: a slide rail sleeve 160 sleeved on the slide rail 120, along the moving direction of the carrier 130, the slide rail sleeve 160 has at least two heat conduction effects; a temperature sensing member 170 disposed on the carrier 130, the temperature sensing member 170 is used to detect the temperature of the slide rail sleeve 160, and the temperature of the slide rail sleeve 160 is used to determine the position of the carrier 130.

[0054] Specifically, the motor assembly 100 further includes a slide rail sleeve 160 sleeved on the slide rail 120. The temperature sensing element 170 is disposed on the carrier 130. The temperature sensing element 170 can move along with the carrier 130 and detect the temperature at the corresponding position of the slide rail sleeve 160. Since the slide rail sleeve 160 has at least two heat conduction effects along the moving direction AB or BA of the carrier 130, the position of the slide rail sleeve 160 detected by the current temperature sensing element 170 can be determined according to the temperature measured by the temperature sensing element 170, so that the position of the carrier 130 can be determined. As described above, by detecting the temperature of the slide rail sleeve 160 by the temperature sensing element 170, the position of the carrier 130 can be determined. Furthermore, when zooming, the current of the coil 140 can be controlled based on the temperature of the slide rail sleeve 160, improving the accuracy of the motor assembly 100.

[0055] Wherein, the number of the slide rails 120 can be multiple, for example: 2, 3, 4, 5, 6, 7, etc. A slide rail sleeve 160 is sleeved on one of the slide rails 120, and a temperature sensing element 170 is disposed on the carrier 130. The stroke of the carrier 130 can be divided into multiple focusing positions. Since the temperatures at various positions of the slide rail sleeve 160 are different along the guiding direction AB or BA of the slide rail 120, the current focusing position of the carrier 130 can be determined according to the temperature detected by the temperature sensing element 170. Moreover, it is not restricted by the stroke of the carrier 130. Therefore, it can be applied to the motor assembly 100 with a large stroke, thus being applicable to cameras with a larger volume, and making the movement of the entire carrier 130 more accurate, achieving more accurate focusing.

[0056] As Figure 4 shown, as a possible implementation manner, the temperature sensing element 170 has a flexible portion 172, and the flexible portion 172 abuts against the slide rail sleeve 160.

[0057] Specifically, the end portion of the temperature sensing element 170 is the flexible portion 172, and the flexible portion 172 abuts against the slide rail sleeve 160. Thus, when the carrier 130 moves, the flexible portion 172 can generate elastic deformation, so that the temperature sensing element 170 always abuts against the slide rail sleeve 160, thereby improving the accuracy of the temperature detection of the slide rail sleeve 160 by the temperature sensing element 170.

[0058] Wherein, the material of the flexible portion 172 can be rubber or silica gel, etc.

[0059] The slide rail 120, the slide rail sleeve 160, and the temperature sensing member 170 form a position sensing structure. The slide rail sleeve 160 is sleeved outside the slide rail 120. The slide rail 120 functions to fix the position of the slide rail sleeve 160 during position sensing. The slide rail sleeve 160 is made of graphene material with high heat dissipation characteristics and high hardness. The slide rail sleeve 160 is in a frustum shape to ensure temperature differences at different positions of the slide rail sleeve 160. One end of the temperature sensing member 170 is connected to the slide rail sleeve 160. The end of the temperature sensing member 170 in contact with the slide rail sleeve 160 is a flexible portion 172. This flexible portion 172 can sense temperature and can always remain in contact with the slide rail sleeve 160 during the focusing process. When the temperature sensing member 170 detects different temperatures at different positions where it contacts the slide rail sleeve 160, it will transmit the current position to the shooting processor of the electronic device, thereby enabling the temperature sensing member 170 to ensure accurate focusing of the camera.

[0060] As a possible implementation manner, the temperature sensing member 170 and the slide rail 120 are electrically connected.

[0061] Specifically, the temperature sensing member 170 and the slide rail 120 are electrically connected, that is, the temperature sensing member 170 is powered and / or transmits signals through the slide rail 120, thereby making the structure of the motor assembly 100 simpler and reducing production costs.

[0062] As a possible implementation manner, the area of one end of the slide rail sleeve 160 is larger than the area of the other end of the slide rail sleeve 160.

[0063] Specifically, the area of one end of the slide rail sleeve 160 is larger than the area of the other end of the slide rail sleeve 160, that is, along the moving direction AB or BA of the carrier 130, the cross-sectional area of the slide rail sleeve 160 is different, and the heat conduction effect is related to the cross-sectional area. By setting the cross-sectional area of the slide rail sleeve 160 to be various, the difference in the heat conduction effect at different positions of the slide rail sleeve 160 along the moving direction AB or BA of the carrier 130 is realized. Such a setting method has a simple structure and is easy to produce.

[0064] As Figure 2 and Figure 4 shown, as a possible implementation manner, the slide rail 120 is cylindrical or prismatic, and the slide rail sleeve 160 is frustum-shaped.

[0065] Specifically, the slide rail 120 is cylindrical or prismatic, and the slide rail sleeve 160 is frustum-shaped, so that the shape of the entire slide rail sleeve 160 is more regular, making the calculation of determining the position of the carrier 130 by temperature more accurate and improving the accuracy of the motor.

[0066] Among them, the slide rail 120 can be cylindrical, triangular prism-shaped, quadrangular prism-shaped, pentagonal prism-shaped, hexagonal prism-shaped, etc., and the slide rail sleeve 160 is frustum-shaped, triangular pyramid frustum-shaped, quadrangular pyramid frustum-shaped, pentagonal pyramid frustum-shaped, hexagonal pyramid frustum-shaped, etc.

[0067] Along the guiding direction AB or BA of the slide rail 120, the slide rail sleeve 160 is frustum-shaped. The temperature sensing element 170 can move along with the carrier 130 to detect the temperature at the corresponding position of the slide rail sleeve 160. Since the slide rail sleeve 160 is frustum-shaped, the heat conduction effects at different positions of the slide rail sleeve 160 are different. Therefore, according to the temperature measured by the temperature sensing element 170, the position of the slide rail sleeve 160 detected by the current temperature sensing element 170 can be determined, and thus the position of the carrier 130 can be determined. As described above, by detecting the temperature of the slide rail sleeve 160 by the temperature sensing element 170, the position of the carrier 130 can be determined. Furthermore, when zooming, the current of the coil 140 can be controlled based on the temperature of the slide rail sleeve 160 to improve the accuracy of the motor assembly 100.

[0068] Since the slide rail sleeve 160 is frustum-shaped, along the guiding direction AB or BA of the slide rail 120, the cross-sectional area of each position of the slide rail sleeve 160 is different, and the corresponding volume also has differences, resulting in different temperatures at each position of the slide rail sleeve 160, with a temperature difference.

[0069] Moreover, the temperature inside the motor assembly 100 rises as a whole. However, since the slide rail sleeve 160 is located in a small space and the slide rail 120 also generates heat during the conduction of electricity, the temperature of the slide rail sleeve 160 is higher than the temperature inside the motor assembly 100, so that the temperature of the slide rail sleeve 160 can be detected by the temperature sensing element 170. And in this application, the position accuracy depends on the accuracy of the temperature sensing element 170. The higher the accuracy of the temperature sensing element 170, the higher the position accuracy of the determined carrier 130.

[0070] Among them, the slide rail 120 is in direct contact with the slide rail sleeve 160, and heat is exchanged through the kinetic energy transfer between molecules. The formula is Q = K×A×ΔT÷L, where Q represents the conduction heat dissipation, K represents the thermal conductivity, A represents the cross-sectional area, ΔT represents the temperature difference at both ends of the heat transfer path, and L represents the length of the heat transfer path. The heat transfer path is through the slide rail sleeve 160. And since the slide rail sleeve 160 is frustum-shaped, when the carrier 130 moves to different positions, the corresponding positions of the slide rail sleeve 160 are different, and the cross-sectional areas corresponding to different positions of the slide rail sleeve 160 are different, so the temperatures corresponding to different positions are also different.

[0071] For example, the temperature of the slide rail sleeve 160 corresponding to the focusing position of the motor assembly 100 is 80°C (the thinnest position of the slide rail sleeve 160) - 100°C (the thickest position of the slide rail sleeve 160). Of course, in other embodiments of the present application, it may also be other temperatures. The accuracy of the temperature sensing element 170 is 1°C. Moreover, during the operation of the motor assembly 100, temperature rise will occur. Specifically, after the motor assembly 100 continuously operates for 5 minutes, the internal temperature of the motor assembly 100 can reach 70°C. To avoid the phenomenon of inaccurate focusing caused by the internal temperature rise of the motor assembly 100, the temperature of the slide rail sleeve 160 can be calibrated, and the calibration process can be executed once per minute.

[0072] Since the temperature of the slide rail sleeve 160 itself is higher than the internal temperature of the motor assembly 100, the temperature sensing element 170 is in contact with the slide rail sleeve 160, and the temperature sensing element 170 only senses the temperature of the slide rail sleeve 160. The focusing stroke of the motor assembly 100 is 200um, which can be divided into 100 focusing positions, and the temperature difference corresponding to adjacent minimum focusing positions is 2°C. When the motor assembly 100 focuses, the temperature sensing element 170 detects and calibrates the temperature of the entire stroke of the slide rail sleeve 160, obtains the temperature difference in the focusing stroke of the slide rail sleeve 160, and thus calibrates the sensed temperatures of different focusing positions on the surface of the slide rail sleeve 160 to ensure the accuracy of the focusing of the motor assembly 100.

[0073] Of course, in other embodiments of the present application, the accuracy of the temperature sensing element 170 can be selected as ±0.1°C, or other accuracies.

[0074] As a possible implementation manner, the slide rail sleeve 160 is made of graphene.

[0075] Specifically, the slide rail sleeve 160 is made of graphene, and graphene has better heat dissipation performance, making the temperature difference at different positions on the entire slide rail sleeve 160 more obvious, so that the position of the carrier 130 can be determined more clearly, and the accuracy of the motor can be improved.

[0076] As Figure 2 shown, as a possible implementation manner, at least two protrusions 132 are provided on the peripheral side of the carrier 130, the coil 140 is arranged between adjacent protrusions 132; the protrusion 132 has a through hole 134, and the slide rail 120 passes through the through hole 134.

[0077] Specifically, at least two protrusions 132 are provided on the peripheral side of the carrier 130, and the coil 140 is arranged between adjacent protrusions 132, that is, the coil 140 is indented into the carrier 130, which helps to reduce the volume of the carrier 130. A through hole 134 is provided on the protrusion 132, and the slide rail 120 passes through the through hole 134, thereby reducing the occupation of the space of the carrier 130 by the slide rail 120, so that the carrier 130 can better carry the camera.

[0078] Among them, the slide rail sleeve 160 also passes through the through hole 134.

[0079] The number of the protrusions 132 can be four, which are respectively arranged at the four corners of the carrier 130. The number of the coils 140 can be four, which are respectively arranged between two adjacent protrusions 132. The number of the magnetic members 150 can be four, which respectively correspond to the four coils 140. Specifically, the four coils 140 are fixed on the four sides of the carrier 130. When the coils 140 are energized, an electromagnetic force is generated between the coils 140 and the magnetic members 150 to drive the carrier 130 to move. The slide rail sleeve 160 is sleeved on a slide rail 120. The temperature sensing member 170 is fixed to the carrier 130. When the carrier 130 moves, the temperature sensing member 170 will move together with the carrier 130. Thus, the temperature sensing member 170 detects different positions of the slide rail sleeve 160. The slide rail 120 is designed to be made of a conductive material to supply power to the coils 140 and the temperature sensing member 170. The slide rail 120 not only plays a role in supporting the movement of the carrier 130, but also supplies power to the coils 140 and the temperature sensing member 170 and transmits the signal of the temperature sensing member 170.

[0080] Such as Figure 1 and Figure 2 shown, as a possible implementation manner, the housing 110 includes: a first housing 112; a second housing 114, one end of the slide rail 120 is connected to the first housing 112, and the other end of the slide rail 120 is connected to the second housing 114; welding feet 116, which are arranged on at least one of the first housing 112 and the second housing 114, and the welding feet 116 are electrically connected to the slide rail 120.

[0081] Specifically, the housing 110 includes a first housing 112, a second housing 114 and welding feet 116. The first housing 112 and the second housing 114 are buckled to protect the carrier 130, the magnetic members 150 and the coils 140 inside. The welding feet 116 are arranged on at least one of the first housing 112 and the second housing 114 and are electrically connected to the slide rail 120, so as to supply power to the slide rail 120 and realize the power supply of the motor assembly 100.

[0082] Specifically, the first housing 112 and the second housing 114 are connected together by a dispensing process, and the two together protect the internal components. The first housing 112 and the slide rail 120 are connected together by a dispensing process, the second housing 114 is connected together by a dispensing process, and the magnetic members 150 and the first housing 112 are connected together by a dispensing process.
