Description

Technical Field

[0001] The present application belongs to the technical field of motor assemblies, and specifically relates to a motor assembly, a camera device, and an electronic device. Background Art

[0002] In the related art, the camera device of an electronic device includes a motor, which includes a housing, a carrier, a position sensor, and a sensing element, with the position sensor being disposed on the carrier. The camera of the camera device is mounted on the carrier, which can drive the position sensor and lens to move relative to the housing. When the electronic device is in a low-temperature or high-temperature environment, temperature changes can cause the carrier to shrink or expand, which in turn causes deviations in the calibrated positions of the position sensor and the sensing element. Thus, under varying temperatures, the motor's movement position is inaccurate, which can cause the motor's focus or anti-shake function to fail. Summary of the Invention

[0003] The present application aims to provide a motor assembly, a camera device and an electronic device, which solve the problem in the related art that the movement position of the motor is inaccurate under changing temperatures, resulting in failure of the motor focus or anti-shake.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes a motor assembly, comprising: a shell; a carrier, located in the shell, the carrier can move relative to the shell, and the carrier is used to fix the lens; a controllable deformable part, provided on the shell; a position detection part; a sensing part, one of the position detection part and the sensing part is provided on the carrier, and the other of the position detection part and the sensing part is provided on the controllable deformable part, and the position detection part and the sensing part cooperate to determine the position of the carrier; wherein the controllable deformable part is used to deform when the carrier is deformed due to temperature changes, and adjust the relative position of the sensing part and the position detection part.

[0006] In a second aspect, an embodiment of the present application provides a camera device, comprising: a lens; and the motor assembly of the first aspect, wherein the lens is disposed on a carrier.

[0007] In a third aspect, an embodiment of the present application proposes an electronic device, comprising: the motor assembly in the first aspect; or the camera device in the second aspect.

[0008] In an embodiment of the present application, the motor assembly includes a housing, a carrier, a position detecting component, a controllable deformation component, and a sensing component.

[0009] The controllable deformation member is arranged on the shell, and the shell serves as a mounting carrier of the controllable deformation member and has the function of mounting and fixing the controllable deformation member.

[0010] The carrier is located within the housing and is capable of moving relative to the housing. It is used to secure the lens; that is, the camera's lens is mounted on the carrier. The carrier can drive the lens's relative movement relative to the housing to meet focus and anti-shake requirements.

[0011] One of the position detecting member and the sensing member is disposed on a carrier, and the other of the position detecting member and the sensing member is disposed on a controllable deformable member. That is, the position detecting member is disposed on a carrier, and the sensing member is disposed on a controllable deformable member. Alternatively, the position detecting member is disposed on a controllable deformable member, and the sensing member is disposed on a carrier. In other words, the carrier serves as a mounting carrier for one of the position detecting member and the sensing member, and has the function of mounting and fixing the one of the position detecting member and the sensing member, while the controllable deformable member serves as a mounting carrier for the other of the position detecting member and the sensing member, and has the function of mounting and fixing the other of the position detecting member and the sensing member.

[0012] Among them, when the carrier is deformed due to changes in ambient temperature, the controllable deformable part will also be deformed, and the deformation trend of the controllable deformable part is adapted to the deformation trend of the carrier. When the carrier is deformed, it will drive one of the position detection part and the sensing part to move, and when the controllable deformable part is deformed, it will drive the other of the position detection part and the sensing part to move. Therefore, when the carrier is deformed due to temperature changes, the controllable deformable part will also deform to adjust the relative position of the sensing part and the position detection part accordingly, so that the position of one of the sensing part and the position detection part can adaptively match the position of the other of the sensing part and the position detection part. In this way, the relative position of the sensing part and the position detection part can be adjusted, the accuracy of the relative position of the sensing part and the position detection part can be guaranteed, the position of the carrier can be accurately determined, and then the position of the lens located on the carrier can be accurately determined, providing effective and reliable structural support for ensuring precise focus or anti-shake, and meeting the use requirements of motor precise focus and anti-shake.

[0031] The following combination Figures 1 to 9 The motor assembly 10 , the imaging device, and the electronic device according to the embodiments of the present application are described.

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the motor assembly 10 according to some embodiments of the present application includes: a shell 100; a carrier 200, which is located in the shell 100, the carrier 200 can move relative to the shell 100, and the carrier 200 is used to fix the lens; a controllable deformable member 300, which is arranged on the shell 100; a position detection member 400; a sensing member 500, one of the position detection member 400 and the sensing member 500 is arranged on the carrier 200, and the other of the position detection member 400 and the sensing member 500 is arranged on the controllable deformable member 300, and the position detection member 400 and the sensing member 500 are used to cooperate to determine the position of the carrier 200; wherein the controllable deformable member 300 is used to deform when the carrier 200 is deformed due to temperature changes, and adjust the relative positions of the sensing member 500 and the position detection member 400.

[0033] The motor assembly 10 according to the embodiment of the present application includes a housing 100 , a carrier 200 , a position detecting member 400 , a controllable deformation member 300 , and a sensing member 500 .

[0034] The controllable deformable member 300 is disposed in the housing 100 . The housing 100 serves as a mounting carrier 200 for the controllable deformable member 300 and has the function of mounting and fixing the controllable deformable member 300 .

[0035] The carrier 200 is located within the housing 100 and is movable relative to the housing 100. The carrier 200 is used to secure the lens. Specifically, the lens of the camera is mounted on the carrier 200. The carrier 200 drives the lens to move relative to the housing 100 to meet the requirements of focusing and anti-shake.

[0036] One of the position detecting member 400 and the sensing member 500 is disposed on the carrier 200, and the other of the position detecting member 400 and the sensing member 500 is disposed on the controllable deformable member 300. That is, the position detecting member 400 is disposed on the carrier 200, and the sensing member 500 is disposed on the controllable deformable member 300. Alternatively, the position detecting member 400 is disposed on the controllable deformable member 300, and the sensing member 500 is disposed on the carrier 200. In other words, the carrier 200 serves as a mounting carrier 200 for one of the position detecting member 400 and the sensing member 500, and has the function of mounting and fixing the one of the position detecting member 400 and the sensing member 500, and the controllable deformable member 300 serves as a mounting carrier 200 for the other of the position detecting member 400 and the sensing member 500, and has the function of mounting and fixing the other of the position detecting member 400 and the sensing member 500.

[0037] When the carrier 200 deforms due to changes in ambient temperature, the controllable deformable member 300 also deforms, and the deformation trend of the controllable deformable member 300 matches the deformation trend of the carrier 200. When the carrier 200 deforms, it drives one of the position detection member 400 and the sensing member 500 to move. When the controllable deformable member 300 deforms, it drives the other of the position detection member 400 and the sensing member 500 to move. Therefore, when the carrier 200 is deformed due to temperature changes, the controllable deformable part 300 will also deform accordingly to adjust the relative positions of the sensing part 500 and the position detection part 400 accordingly, so that the position of one of the sensing part 500 and the position detection part 400 can adaptively match the position of the other of the sensing part 500 and the position detection part 400. In this way, the relative positions of the sensing part 500 and the position detection part 400 can be adjusted, the accuracy of the relative positions of the sensing part 500 and the position detection part 400 can be ensured, the position of the carrier 200 can be accurately determined, and then the position of the lens located on the carrier 200 can be accurately determined, providing effective and reliable structural support to ensure precise focus or anti-shake, and can meet the use requirements of motor precise focus and anti-shake.

[0038] In some embodiments, the controllable deformation element 300 includes a thermal deformation element or an electro-deformation element.

[0039] In this embodiment, the type of the controllable deformation member 300 is defined such that the controllable deformation member 300 includes a thermal deformation member or an electro-deformation member.

[0040] When the controllable deformable member 300 includes a thermo-induced deformable member, the deformation of the controllable deformable member 300 is changed by thermal actuation. For example, the controllable deformable member 300 contracts as the temperature increases, and expands as the temperature decreases. For example, the controllable deformable member 300 expands as the temperature increases, and contracts as the temperature decreases. This arrangement can meet the requirements for adjusting the relative position of the sensing member 500 and the position detection member 400.

[0041] When the controllable deformable member 300 includes an electro-deformable member, the controllable deformable member 300 is electrically connected to the controller of the electronic device. The controller can control the controllable deformable member 300 to input the required current, voltage, etc., thereby changing the expansion and contraction amount of the controllable deformable member 300 and adjusting the relative position of the sensing member 500 and the position detection member 400. For example, if the position detection member 400 is provided on the carrier 200 and the sensing member 500 is provided on the controllable deformable member 300, the controller can control the deformation amount and deformation angle of the controllable deformable member 300 according to the offset position of the position detection member 400 provided on the carrier 200, thereby causing the sensing member 500 to move toward the position detection member 400, so that the relative displacement between the position detection member 400 and the sensing member 500 is offset, thereby ensuring the relative position of the position detection member 400 and the sensing member 500, and realizing precise focusing and anti-shake of the motor.

[0042] In some other embodiments, the controllable deformable member 300 includes a thermo-induced deformable member and an electro-induced deformable member. The thermo-induced deformable member is driven by heat to achieve the purpose of changing the deformation amount of the controllable deformable member 300. For example, the controllable deformable member 300 contracts as the temperature rises, and the controllable deformable member 300 expands as the temperature drops. For example, the controllable deformable member 300 expands as the temperature rises, and the controllable deformable member 300 contracts as the temperature drops. This setting can meet the use requirements of adjusting the relative position of the sensing member 500 and the position detection member 400. At the same time, the controllable deformable member 300 is electrically connected to the controller of the electronic device, and the controller can control the controllable deformable member 300 to input the required current, voltage, etc., thereby changing the expansion and contraction amount of the controllable deformable member 300 and achieving the purpose of adjusting the relative position of the sensing member 500 and the position detection member 400. Taking the example of the position detection part 400 being arranged on the carrier 200 and the sensing part 500 being arranged on the controllable deformable part 300, the controller can control the deformation amount and deformation angle of the controllable deformable part 300 according to the offset position of the position detection part 400 arranged on the carrier 200, so that the sensing part 500 can be moved toward the position detection part 400, so that the relative displacement between the position detection part 400 and the sensing part 500 is offset, so as to ensure the relative position of the position detection part 400 and the sensing part 500, and realize precise focusing and anti-shake of the motor.

[0043] Exemplarily, the controllable deformable member 300 comprises a shape memory alloy. The controllable deformable member 300 can change shape as the internal temperature of the motor changes, thereby compensating for dimensional changes of the carrier 200 caused by temperature changes. This allows the relative positions of the position detecting member 400 or the sensing member 500 disposed on the carrier 200 and the sensing member 500 or the position detecting member 400 disposed on the controllable deformable member 300 to be adjusted, thereby ensuring the accuracy of the positions of the position detecting member 400 and the sensing member 500.

[0044] The temperature at which the shape memory alloy begins to deform is called the austenite start temperature (Austenite Start temperature), also known as the A phase transition temperature. When the material temperature of the shape memory alloy rises to the As temperature, the material of the shape memory alloy undergoes a phase transition from the martensite phase (Martensite) to the austenite phase (Austenite). At the same time, the shape of the shape memory alloy material will change accordingly. In the material of the shape memory alloy, the As temperature usually varies with the alloy composition, and is also affected by factors such as the processing method and heat treatment method of the shape memory alloy material.

[0045] In some embodiments, when the temperature changes, one of the carrier 200 and the controllably deformable member 300 expands, and the other of the carrier 200 and the controllably deformable member 300 contracts.

[0046] In this embodiment, the mating structure of the carrier 200 and the controllable deformable member 300 is further defined such that, when the temperature changes, one of the carrier 200 and the controllable deformable member 300 expands, while the other contracts. For example, the carrier 200 expands as the temperature increases, contracts as the temperature decreases, and the controllable deformable member 300 contracts as the temperature increases, while the controllable deformable member 300 expands as the temperature decreases. For another example, the carrier 200 contracts as the temperature increases, expands as the temperature decreases, and the controllable deformable member 300 expands as the temperature increases, while the controllable deformable member 300 contracts as the temperature decreases.

[0047] Since the carrier 200 and the controllable deformable part 300 have opposite deformation tendencies with temperature changes, the requirement of adaptively adjusting the position of one of the sensing part 500 and the position detection part 400 relative to the other of the sensing part 500 and the position detection part 400 can be met to ensure the relative position of the sensing part 500 and the position detection part 400, thereby providing effective structural support for ensuring precise focusing and anti-shake of the motor assembly 10.

[0048] Figure 6 The shape of the controllable deformation member 300 at 0°C is shown. Figure 7 The shape of the controllable deformation member 300 at 25°C is shown. Figure 8 The shape of the controllably deformable member 300 at 70° C. is shown. It can be seen that the controllably deformable member 300 contracts as the temperature rises.

[0049] In some embodiments, when the controllable deformable member 300 and the carrier 200 are deformed due to temperature changes, the controllable deformable member 300 and the carrier 200 drive the position detecting member 400 and the sensing member 500 to move along the height direction of the housing 100 .

[0050] In this embodiment, the direction in which the controllable deformable member 300 and the carrier 200 drive the position detecting member 400 and the sensing member 500 to move is defined. Specifically, when the controllable deformable member 300 and the carrier 200 are deformed due to temperature changes, the controllable deformable member 300 and the carrier 200 drive the position detecting member 400 and the sensing member 500 to move along the height direction of the housing 100.

[0051] For example, the position detection element 400 is disposed on the carrier 200 and the sensing element 500 is disposed on the controllable deformation element 300. Figure 5 The arrows in FIG. 4 indicate the movement trajectories of the position detection member 400 and the sensing member 500. Figures 6 to 8 The diagram illustrates the deformation trend of the controllable deformable member 300 as the temperature changes. As the temperature rises, the carrier 200 expands, driving the position detecting member 400 to move upward along the height of the housing 100. The controllable deformable member 300 contracts as the temperature rises, driving the sensing member 500 to move upward along the height of the housing 100. The motion trajectories of the position detecting member 400 and the sensing member 500 match, ensuring their relative positional relationship.

[0052] In some other embodiments, the carrier 200 contracts as the temperature rises to drive the position detection component 400 to move downward along the height direction of the shell 100, and the controllable deformable component 300 expands as the temperature rises to drive the sensing component 500 to move downward along the height direction of the shell 100. The movement trajectories of the position detection component 400 and the sensing component 500 match, which can ensure the relative position relationship between the position detection component 400 and the sensing component 500.

[0053] In some other embodiments, when the controllable deformable member 300 and the carrier 200 are deformed due to temperature changes, the controllable deformable member 300 and the carrier 200 also drive the position detecting member 400 and the sensing member 500 to move in a height direction perpendicular to the housing 100 .

[0054] In some embodiments, as Figure 2 and Figure 4 As shown, the carrier 200 is provided with an avoidance position 210 , and the controllable deformable member 300 is located at the avoidance position 210 ; the position detection member 400 or the sensing member 500 provided on the carrier 200 is arranged opposite to the avoidance position 210 .

[0055] In this embodiment, the structure of the carrier 200 is further defined.

[0056] The carrier 200 is provided with a clearance 210, and the controllable deformable member 300 is located in the clearance 210. The clearance 210 is used to avoid the controllable deformable member 300, and thus avoid the sensing member 500 or the position detection member 400 provided on the controllable deformable member 300. In this way, when the controllable deformable member 300 deforms to drive the sensing member 500 or the position detection member 400 to move, it will not interfere with the carrier 200. The clearance 210 will not hinder the deformation of the controllable deformable member 300, and the relative positions of the position detection member 400 and the sensing member 500 can be satisfied.

[0057] In addition, the position detecting member 400 or the sensing member 500 provided on the carrier 200 is arranged opposite to the avoidance position 210 to provide structural support for ensuring the positional relationship between the position detecting member 400 and the sensing member 500 is adjusted.

[0058] In some embodiments, a portion of the outer peripheral wall of the carrier 200 is recessed to form a space 210 .

[0059] In this embodiment, the structure of the carrier 200 is further defined such that a portion of the outer peripheral wall of the carrier 200 is recessed to form a clearance area 210. In other words, the location of the clearance area 210 is defined.

[0060] This arrangement enables the avoidance space 210 to not only effectively avoid the controllable deformable member 300 , but also reduces the difficulty of processing the motor assembly 10 , thereby improving the processing convenience of the product and reducing the production cost of the product.

[0061] In some other embodiments, a space 210 is defined inside the carrier 200 .

[0062] In some embodiments, as Figure 4 As shown, one of the position detecting member 400 and the sensing member 500 is located between the other of the position detecting member 400 and the sensing member 500 and the controllable deformation member 300 .

[0063] In this embodiment, the matching structure of the position detecting member 400 , the sensing member 500 and the controllable deformation member 300 is further defined.

[0064] One of the position detecting member 400 and the sensing member 500 is located between the other of the position detecting member 400 and the sensing member 500 and the controllable deformable member 300. That is, the position detecting member 400 is located between the sensing member 500 and the controllable deformable member 300, and the position detecting member 400 is disposed on the side of the controllable deformable member 300 facing the sensing member 500. Alternatively, the sensing member 500 is located between the position detecting member 400 and the controllable deformable member 300, and the sensing member 500 is disposed on the side of the controllable deformable member 300 facing the position detecting member 400.

[0065] This arrangement can prevent the controllable deformable member 300 from interfering with the position detection member 400 and the sensing member 500 , thereby ensuring the effectiveness and stability of the sensing signal transmission between the position detection member 400 and the sensing member 500 , and providing structural support for determining the position of the carrier 200 .

[0066] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a concave portion 310 is provided on the side of the controllable deformation member 300 facing away from the position detection member 400 and the sensing member 500 .

[0067] In this embodiment, the structure of the controllable deformable member 300 is further defined, with a recess 310 provided on the side of the controllable deformable member 300 facing away from the position detection member 400 and the sensing member 500. This arrangement ensures a uniform thickness of the controllable deformable member 300 and controllable deformation of the controllable deformable member 300, enabling the controllable deformable member 300 to deform in a predetermined direction. Furthermore, the recess 310 limits the relative displacement of the controllable deformable member 300 and the housing 100, thereby ensuring the effective and reliable assembly of the controllable deformable member 300 and the housing 100.

[0068] In some embodiments, as Figure 2 As shown, the motor assembly 10 also includes: a first mating piece 600; a second mating piece 700, one of the first mating piece 600 and the second mating piece 700 is arranged on the shell 100, and the other of the first mating piece 600 and the second mating piece 700 is arranged on the carrier 200, and the first mating piece 600 and the second mating piece 700 cooperate to drive the carrier 200 to move relative to the shell 100.

[0069] In this embodiment, the structure of the motor assembly 10 is further defined, and the motor assembly 10 further includes a first mating piece 600 and a second mating piece 700 .

[0070] One of the first and second fittings 600 and 700 is disposed on the housing 100, while the other is disposed on the carrier 200. The housing 100 serves as a mounting carrier 200 for one of the first and second fittings 600 and 700, and has the function of mounting and securing the first and second fittings 600 and 700. The carrier 200 serves as a mounting carrier 200 for the other of the first and second fittings 600 and 700, and has the function of mounting and securing the other of the first and second fittings 600 and 700. This arrangement ensures that the first and second fittings 600 and 700 are dimensionally compatible.

[0071] The carrier 200 can move relative to the housing 100 under the action of the first mating part 600 and the second mating part 700. At the same time, the lens can move relative to the housing 100 driven by the carrier 200, providing structural support for the motor assembly 10 to have anti-shake and focusing functions.

[0072] In some embodiments, as Figure 2 As shown, one of the position detection component 400 and the sensing component 500 is located on the first side 230 of the carrier, and the other of the first matching component 600 and the second matching component 700 is located on the second side 240 of the carrier; the first side 230 of the carrier and the second side 240 of the carrier are adjacent sides of the carrier 200.

[0073] In this embodiment, the structure of the motor assembly 10 is further defined.

[0074] One of the position detecting element 400 and the sensing element 500 is located on the first side 230 of the carrier, and the other of the first matching element 600 and the second matching element 700 is located on the second side 240 of the carrier.

[0075] For example, the position detecting member 400 is disposed on the first side 230 of the carrier, and the second matching member 700 is disposed on the second side 240 of the carrier. The first side 230 and the second side 240 of the carrier are adjacent sides of the carrier 200. In other words, the position detecting member 400 and the second matching member 700 are located on adjacent sides of the carrier 200. This prevents signal interference, ensures the accuracy of the position detecting member 400 and the sensing member 500 in cooperating to determine the position of the carrier 200, and ensures the accuracy of the first matching member 600 and the second matching member 700 in cooperating to drive the movement of the carrier 200.

[0076] At the same time, this structural arrangement can also prevent one of the position detecting component 400 and the sensing component 500 from interfering with the other of the first matching component 600 and the second matching component 700 at the installation position, thereby facilitating assembly.

[0077] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the housing 100 includes: a housing body 110 ; a base 120 connected to one side of the housing body 110 ; a controllable deformation member 300 disposed on the base 120 ; and a carrier 200 located between the housing body 110 and the base 120 .

[0078] In this embodiment, the housing 100 includes a housing body 110 and a base 120 .

[0079] The base 120 is connected to one side of the housing body 110 .

[0080] The controllable deformable member 300 is mounted on the base 120. The base 120 serves as the mounting carrier 200 for the controllable deformable member 300 and has the function of mounting and fixing the controllable deformable member 300. This ensures the positional relationship between the controllable deformable member 300 and the carrier 200, and thus the positional relationship between the sensing member 500 and the position detection member 400.

[0081] In some other embodiments, the controllable deformation member 300 is disposed on the shell body 110 .

[0082] In some embodiments, as Figure 2 and Figure 4 As shown, the motor assembly 10 also includes: a plurality of slide rails 800, which are arranged in the shell 100, the carrier 200 is slidably connected to the slide rails 800, and the plurality of slide rails 800 are arranged at intervals around the center of the carrier 200; the first matching part 600 includes a coil, and the second matching part 700 includes a first magnetic part; the position detection part 400 includes a Hall detection part, and the induction part 500 includes a second magnetic part.

[0083] In this embodiment, the structure of the motor assembly 10 is further defined. The motor assembly 10 also includes a plurality of slide rails 800. The plurality of slide rails 800 are all arranged in the shell 100. The carrier 200 is slidingly connected to each slide rail 800. The carrier 200 can move along the length direction of the slide rail 800 to ensure the trajectory of the carrier 200 relative to the shell 100.

[0084] Among them, multiple slide rails 800 are arranged at intervals around the center of the carrier 200. This arrangement can increase the guiding area and guiding angle of the guide rails and the carrier 200, so that the carrier 200 can slide smoothly as a whole, avoiding the occurrence of tilting or even jamming of the carrier 200, and ensuring the accuracy and smoothness of the movement of the carrier 200 relative to the shell 100.

[0085] The first mating component 600 includes a coil, and the second mating component 700 includes a first magnetic component. When the coil is energized, a first magnetic field is generated around the coil, and a second magnetic field is generated around the first magnetic component. The interaction between the first and second magnetic fields effectively drives the carrier 200 to move relative to the housing 100.

[0086] Exemplarily, the first magnetic member includes any one of the following or a combination thereof: a samarium cobalt magnet, a ferrite magnet, a neodymium iron boron magnet, and an alnico magnet.

[0087] The position detection element 400 includes a Hall detection element, and the induction element 500 includes a second magnetic element. The Hall detection element and the second magnetic element cooperate to determine the position of the carrier 200 .

[0088] Exemplarily, the carrier 200 is a plastic part.

[0089] According to some other embodiments of the present application, a camera device is provided, including: a lens; and a motor assembly 10 according to any of the above embodiments, wherein the lens is disposed on a carrier 200 .

[0090] The camera device provided herein includes a lens and a motor assembly 10 according to any of the above embodiments. The lens is mounted on a carrier 200, which drives the lens to move to meet the requirements of focusing and anti-shake. The camera device has all the beneficial effects of the motor assembly 10 described above, which will not be detailed here.

[0091] According to some further embodiments of the present application, an electronic device is proposed, including: the motor assembly 10 of any one of the above embodiments; or the camera device of the above embodiments.

[0092] The electronic device provided in the present application includes a motor assembly 10 or a camera device. Therefore, all the beneficial effects of the motor assembly 10 or the camera device are not described here one by one.

[0093] For example, the electronic device can be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also known as an AR (Augmented Reality) device), a virtual reality device (also known as a VR (Virtual Reality) device) and a handheld game console, etc.

[0094] Exemplarily, the induction element 500 includes a sensing magnet, the position detection element 400 includes a Hall detection element, the first matching element 600 includes a coil, and the second matching element 700 includes a driving magnet.

[0095] For example, this application utilizes a controllable deformable element 300, affixing the sensing magnet to the structure of the controllable deformable element 300. Taking advantage of the temperature-dependent deformation of the controllable deformable element 300, when the temperature rises, the controllable deformable element 300 contracts, and when the temperature drops, the controllable deformable element 300 expands. The motor carrier 200 expands with increasing temperature and contracts with decreasing temperature. This temperature-dependent deformation of the controllable deformable element 300 compensates for the effect of temperature on the motor's focus position.

[0096] For example, the present application utilizes the characteristics that the carrier 200 and the controllable deformable member 300 have opposite deformation trends with temperature changes to compensate for the influence of the change in the internal temperature of the motor on the deviation of the focus position or the anti-shake position.

[0097] Illustratively, the controllable deformation member 300 is fixed on the base 120 of the housing 100 , the sensing magnet is fixed on the surface of the controllable deformation member 300 , and the Hall detection member is fixed on the carrier 200 , thereby ensuring the accuracy of the relative position of the sensing magnet and the Hall detection member.

[0098] For example, Figure 2 As shown, the motor assembly 10 includes a housing 110 , a slide rail 800 , a driving magnet, a coil, a Hall detection element, a sensing magnet, a controllable deformation element 300 , a base 120 , a welding foot 900 and a carrier 200 .

[0099] Exemplarily, the housing body 110 is a plastic part, and the housing body 110 is used to protect components inside the motor assembly 10 .

[0100] Exemplarily, the slide rail 800 is used to support the movement direction of the carrier 200 and to connect the circuit for the coil.

[0101] Exemplarily, the driving magnet and the coil generate electromagnetic force to provide power for the movement of the carrier 200 .

[0102] Exemplarily, the coil and the magnet generate electromagnetic force to provide power for the movement of the carrier 200 .

[0103] Exemplarily, the Hall detection element is used to sense the magnitude of the magnetic field force of the facing sensing magnet.

[0104] Exemplarily, the sensing magnet is used to generate a magnetic field, and the generated magnetic field is sensed by the Hall detection element.

[0105] For example, the controllable deformation member 300 can sense temperature changes to drive the sensing magnet to move.

[0106] Illustratively, the base 120 is used to protect components inside the motor assembly 10 .

[0107] Illustratively, solder pins 900 provide positive and negative voltages to the motor.

[0108] For example, the carrier 200 is used to fix the lens, and the carrier 200 can drive the lens to move together to achieve the focusing function and anti-shake function of the camera device.

[0109] For example, Figure 3As shown, the shell body 110 and the base 120 are connected together by a dispensing process. The shell body 110 and the base 120 cooperate to protect the components inside the motor assembly 10. The shell body 110 and the slide rail 800 are connected together by a dispensing process. The shell body 110 fixes the driving magnet by a dispensing process. The carrier 200 can move along the length direction of the four slide rails 800. The coil is fixed on the four sides of the carrier 200. When the coil is energized, an electromagnetic force is generated between it and the driving magnet, driving the carrier 200 to move. The Hall detection element is fixed to the carrier 200. The controllable deformation element 300 is fixed to the sensing magnet, and the controllable deformation element 300 is fixed to the surface of the base 120.

[0110] For example, Figure 4 As shown, the Hall effect detector, sensing magnet, controllable deformable member 300, and base 120 are the core structures for compensating the focus position and compensating the anti-shake position of the motor assembly 10. The specific compensation principle is: taking advantage of the characteristic that the material of the controllable deformable member 300 deforms with temperature changes, the controllable deformable member 300 contracts when the temperature rises, and expands when the temperature drops. The sensing magnet is fixed to the controllable deformable member 300. When the internal temperature of the motor assembly 10 rises, the carrier 200 expands with the temperature rise. At this time, the controllable deformable member 300 is affected by the internal temperature change of the motor assembly 10 and contracts, thereby pushing the deformation direction and change amount of the sensing magnet and the carrier 200 to be consistent, so that the relative position of the sensing magnet and the Hall effect detector remains unchanged from the relative position at room temperature (25°C). Conversely, when the internal temperature of the motor assembly 10 decreases, the carrier 200 contracts with the temperature drop. At this point, the controllable deformable member 300 is affected by the temperature drop within the motor assembly 10, causing it to expand. This causes the sensing magnet and carrier 200 to deform in the same direction and by the same amount, thus ensuring that the relative position of the sensing magnet and the Hall effect sensor remains unchanged from their relative positions at room temperature (25°C). By utilizing the temperature-dependent deformation of the controllable deformable member 300, the effect of the temperature within the motor assembly 10 on the deviation of the motor's focus and anti-shake positions is offset, ensuring the accuracy of the motor assembly 10's focus and anti-shake performance.

[0111] like Figure 5 As shown in the figure, when the camera device is in a high-temperature environment, the carrier 200 expands to drive the Hall effect detector upward (the arrow indicates the direction of movement of the carrier 200), and the controllable deformable member 300 contracts to push the sensing magnet to move, thereby ensuring that the relative position of the Hall effect detector and the sensing magnet does not shift. Conversely, when the camera device is in a low-temperature environment, the carrier 200 contracts to drive the Hall effect detector downward, and the controllable deformable member 300 contracts to push the sensing magnet to move, thereby ensuring that the relative position of the Hall effect detector and the sensing magnet does not shift.

[0112] Figures 6 to 8 The shapes of the controllable deformable member 300 at different temperatures are shown. Utilizing the characteristic that the controllable deformable member 300 deforms with temperature, the controllable deformable member 300 contracts when the temperature rises, and expands when the temperature drops.

[0113] Figure 9 The figure shows the characteristics of the deformation of the controllable deformable member 300 and the carrier 200 changing with temperature. The deformation trends of the controllable deformable member 300 and the carrier 200 changing with temperature are exactly opposite, which can compensate for the influence of temperature change on the deviation of the anti-shake position and the focus position.
