Technical Field

[0072] Figure 1 is a schematic structural diagram of a drive assembly 100 according to an exemplary embodiment. Figure 2 yes Figure 1 The front view of the middle drive assembly 100, Figure 3 yes Figure 2 A partially enlarged schematic diagram of the middle drive assembly 100, Figure 4 yes Figure 1 A side view of the drive assembly 100 is shown. Figure 1-Figure 4As shown, the driving assembly 100 may include a first bracket 1, a second bracket 2, a first elastic member 3 and a first memory alloy elastic wire 4. The first bracket 1 and the second bracket 2 may be slidably connected along a first direction, that is, Figure 1 The first bracket 1 and the second bracket 2 can slide back and forth in the direction indicated by arrow A. The first bracket 1 may include a first mounting portion 11, and the second bracket 2 may include a second mounting portion 21. After the first bracket 1 and the second bracket 2 are slidably connected, the first mounting portion 11 and the second mounting portion 21 can be arranged opposite each other along the first direction. One end of the first elastic member 3 can be connected to the first mounting portion 11 and the other end can be connected to the second mounting portion 21, so that the deformation direction of the first elastic member 3 is parallel to the first direction. One end of the first memory alloy elastic wire 4 is connected to the first bracket 1 and the other end can be connected to the second bracket 2. Based on this, when the first memory alloy elastic wire 4 is energized and tightened and in a tightened state, the tightening and contraction of the first memory alloy elastic wire 4 can pull the first bracket 1 and the second bracket 2 to slide relative to each other, and the first mounting portion 11 and the second mounting portion 21 move closer to each other in the first direction, and the first elastic member 3 is compressed by the first mounting portion 11 and the second mounting portion 21. When the first memory alloy elastic wire 4 is de-energized and relaxed and in a relaxed state, the force acting on the first bracket 1 and the second bracket 2 disappears, the first elastic member 3 recovers its deformation, pushing the first bracket 1 and the second bracket 2 to slide relative to each other, and the first mounting portion 11 and the second mounting portion 21 move away from each other in the first direction, thereby achieving a change in the relative positional relationship between the first bracket 1 and the second bracket 2. In the embodiment provided in the present disclosure, the end of the first memory alloy elastic wire 4 connected to the first bracket 1 can be connected to the first mounting portion 11 to reduce losses during power transmission and improve the mechanical efficiency of the drive assembly 100.

[0073] In the technical solution disclosed herein, the first memory alloy elastic wire 4 provides a force in a tightened state, causing the first mounting portion 11 and the second mounting portion 21 to move closer to each other. When the first memory alloy elastic wire 4 is in a relaxed state, the first elastic member 3 recovers its deformation and provides a force that causes the first mounting portion 11 and the second mounting portion 21 to move away from each other, thereby achieving a switching of the relative positional relationship between the first bracket 1 and the second bracket 2. Compared to the related art scheme of achieving power transmission through a gear transmission assembly or a lead screw, the structure of the drive assembly 100 can be simplified and the occupied space can be reduced. The embodiments disclosed herein are described by taking the example of the first memory alloy elastic wire 4 switching to a tightened state when powered on and switching to a relaxed state when powered off. In other embodiments, the tightening and loosening of the first memory alloy elastic wire 4 can also be achieved by adjusting the temperature, and the present disclosure is not limited to this.

[0074] exist Figure 1-Figure 4In the embodiment shown, the first bracket 1 and the second bracket 2 can be stacked and arranged in the same overall direction. In order to achieve the relative arrangement of the first mounting portion 11 and the second mounting portion 21 in the first direction in this stacked structure, the second bracket 2 may include an opening 23, and the second mounting portion 21 may extend upward from the edge of the opening 23. The first mounting portion 11 of the first bracket 1 may pass through the opening 23 and be arranged relative to the second mounting portion 21, which is beneficial to reducing the occupied space of the drive assembly 100. In other cases, the first bracket 1 may include an opening 23, the first mounting portion 11 may extend upward from the edge of the opening 23, and the second mounting portion 21 of the second bracket 2 may pass through the opening 23 and be arranged relative to the first mounting portion 11. This is not limited in this disclosure. In some other embodiments, the first bracket 1 and the second bracket 2 may also be stacked and arranged basically in a cross shape or a T-shape. The specific design can be as needed, and this is not limited in this disclosure.

[0075] In the above embodiment, when the first elastic member 3 recovers its deformation, causing the first mounting portion 11 and the second mounting portion 21 to move away from each other to the target position, the first elastic member 3 may be in a natural state, or in a slightly extended or slightly compressed state. At this time, the relative positional relationship between the first mounting portion 11 and the second mounting portion 21 can be maintained by the first elastic member 3. When the first mounting portion 11 and the second mounting portion 21 approach each other along the first direction to the target position, the first elastic member 3 is compressed, thereby applying a force to the first mounting portion 11 and the second mounting portion 21. Therefore, in order to maintain the relative positional relationship between the first mounting portion 11 and the second mounting portion 21, in one embodiment, the first memory alloy wire 4 can be controlled to remain in a continuously tightened state. The force exerted by the first memory alloy wire 4 on the first bracket 1 and the second bracket 2 offsets the force exerted by the first elastic member 3 on the first mounting portion 11 and the second mounting portion 21, thereby allowing the first mounting portion 11 and the second mounting portion 21 to maintain their current relative positional relationship. In this embodiment, when the first mounting portion 11 and the second mounting portion 21 need to be moved away from each other, the first memory alloy elastic wire 4 can be powered off to switch to a relaxed state.

[0076] In another embodiment, Figure 1-Figure 4As shown, the second bracket 2 may include a rotating shaft 22, which may be perpendicular to the plane in which the first bracket 1 and the second bracket 2 slide relative to each other. The driving assembly 100 may also include a buckle 5 and a second elastic member 6, wherein the buckle 5 may be rotatably connected to the rotating shaft 22, and one end of the second elastic member 6 may be connected to the buckle 5 and the other end may be connected to the first bracket 1. Based on this, when the first memory alloy elastic wire 4 is in a tightened state and the first mounting portion 11 and the second mounting portion 21 approach each other along the first direction, the first mounting portion 11 can press the buckle 5 to make the buckle 5 rotate around the rotating shaft 22, thereby compressing the second elastic member 6 until the first mounting portion 11 and the buckle 5 are limited in the first direction, that is, when the first mounting portion 11 and the buckle 5 are set along the first direction, the first mounting portion 11 no longer presses the buckle 5, and the second elastic member 6 can push the buckle 5 to reset. At this time, the driving component 100 can switch to the contracted state, and the relative position relationship between the first mounting portion 11 and the second mounting portion 21 can be maintained through the abutment between the buckle 5 and the first mounting portion 11. The driving component 100 can be maintained in a compressed state, so that the first memory alloy elastic wire 4 can be powered off after the abutment between the buckle 5 and the first mounting portion 11, which is beneficial to saving energy consumption. When the drive assembly 100 switches from the compressed state to the pop-up state, the buckle 5 can rotate relative to the rotating shaft 22 to compress the second elastic member 6, the buckle 5 and the first mounting portion 11 are released from the limit, the first elastic member 3 is reset, and provides a force to the first mounting portion 11 and the second mounting portion 21, so that the first mounting portion 11 and the second mounting portion 21 move away from each other until the first elastic member 3 returns to its natural state, and the drive assembly 100 switches to the pop-up state. At this time, the drive assembly 100 can be maintained in the pop-up state by the force of the first elastic member 3.

[0077] In this embodiment, the buckle 5 can cooperate with the first mounting portion 11 to limit the position, allowing the drive assembly 100 to remain in a compressed state. The buckle 5 can then be rotated relative to the rotating shaft 22 to release the limit, allowing the drive assembly 100 to switch to the pop-up state. In one embodiment, the buckle 5 can be driven by a motor or other power element to rotate relative to the rotating shaft 22 to release the limit. In other embodiments, such as the embodiments provided in the present disclosure, the drive assembly 100 can also include a second memory alloy elastic wire 7, one end of which is connected to the buckle 5 and the other end of which can be connected to the second bracket 2. Based on this, when the driving component 100 switches from the compressed state to the pop-up state, the second memory alloy elastic wire 7 is in the energized state, that is, in the tightened state. At this time, the second memory alloy elastic wire 7 can pull the buckle 5 to rotate relative to the rotating shaft 22 to release the limit on the first mounting part 11, the first elastic member 3 is reset, and the first mounting part 11 and the second mounting part 21 are away from each other; and when the driving component 100 switches from the pop-up state to the compressed state, the second memory alloy elastic wire 7 is in the de-energized state, that is, in the relaxed state. In the process of the first memory alloy elastic wire 4 pulling the first mounting part 11 and the second mounting part 21 closer to each other, the first mounting part 11 can press the buckle 5 along the buckle 5 toward the side of the first mounting part 11, so that the buckle 5 moves relative to the rotating shaft 22, and the second elastic member 6 is compressed. Until the buckle 5 and the first mounting part 11 are limited, the second elastic member 6 is reset and the driving component 100 switches to the compressed state. The second memory alloy spring wire 7 can be energized at the moment the drive assembly 100 needs to switch to the compressed state, and can be deenergized at any time after the buckle 5 and the first mounting portion 11 are released from the restraint. This disclosure is not limited to this. In this embodiment, the technical solution of using the second memory alloy spring wire 7 to pull the buckle 5 relative to the rotating shaft 22 to release the restraint can further simplify the structure of the drive assembly 100 compared to solutions that use a power element such as a motor to drive the buckle 5 to rotate.

[0078] like Figure 4As shown, the buckle 5 may include a rotating portion 51 and a tail portion 52, the rotating portion 51 may be rotatably connected to the rotating shaft 22, the tail portion 52 may extend from the rotating portion 51 toward the second mounting portion 21, the middle portion of the rotating portion 51 and the tail portion 52 may be connected to one end of the second elastic member 6, the tail portion 52 may include a surface 522 facing the second mounting portion 21, and when the drive assembly 100 switches from the pop-up state to the compressed state, the second mounting portion 21 may apply a force to the buckle 5 through the surface 522 to rotate it around the rotating shaft 22. The tail portion 52 may include an abutment surface 521 for limiting the first mounting portion 11 and the second mounting portion 21. When the first memory alloy wire 4 pulls the first mounting portion 11 and the second mounting portion 21 closer to each other, the first mounting portion 11 can press against the surface of the tail portion 52 set toward the first mounting portion 11, so that the buckle 5 rotates. When the drive assembly 100 switches to the compression state, the first mounting portion 11 can abut against the abutment surface 521, thereby limiting the first mounting portion 11 in the first direction.

[0079] In an exemplary embodiment provided by the present disclosure, the second bracket 2 may include a bracket body 24, a first pulley 25, and a second pulley 26. The rotating shaft 22 may be connected to the bracket body 24, and the first pulley 25 and the second pulley 26 may both be connected to the bracket body 24. The first pulley 25, the second pulley 26, and the rotating shaft 22 may extend in the same direction relative to the bracket body 24. The second memory alloy elastic wire 7 may be drawn out from the buckle 5 and wrapped at least once around the first pulley 25 and the second pulley 26 before being connected to the bracket body 24. Based on this, the first pulley 25 and the second pulley 26 can, on the one hand, limit the position of the second memory alloy elastic wire 7 in a relaxed state. On the other hand, if the length of the second memory alloy elastic wire 7 is required to be the same, the first pulley 25 and the second pulley 26 can shorten the length of the second memory alloy elastic wire 7 on the drive assembly 100, thereby shortening the overall length of the drive assembly 100. Among them, the first pulley 25 and the second pulley 26 can be rotatably connected to the bracket body 24 respectively, the first pulley 25 can include a first matching groove 251, and the second pulley 26 can include a second matching groove 261. The second memory alloy elastic wire 7 can be partially wound in the first matching groove 251 and the second matching groove 261, so that each strand of the second memory alloy elastic wire 7 wound on the first pulley 25 can be separated through the first matching groove 251, and each strand of the second memory alloy elastic wire 7 wound on the second pulley 26 can be separated through the second matching groove 261, so as to avoid the second memory alloy elastic wires 7 from being entangled or knotted with each other.

[0080] In this embodiment, taking the second bracket 2 including two pulleys, the first pulley 25 and the second pulley 26 as an example, in other embodiments, the second bracket 2 may also include only one pulley or may include three or more pulleys. When the second bracket 2 includes multiple pulleys, the second memory alloy elastic wire 7 can be led out from the buckle 5 and wound around each pulley at least once in accordance with a certain winding rule before being connected to the bracket body 24.

[0081] Similarly, the first pulley 25 and the second pulley 26 can also be used to wind the first memory alloy elastic wire 4. Specifically, the first memory alloy elastic wire 4 can be led out from the second bracket 2 and wound around the first pulley 25 and the second pulley 26 at least once according to a certain pattern before being connected to the first bracket 1. In this way, when the same length of the first memory alloy elastic wire 4 is required, the size of the drive assembly 100 can be shortened by winding around the first pulley 25 and the second pulley 26 in a linear segment relative to the first memory alloy elastic wire 4. Specifically, the first memory alloy elastic wire 4 can be wound into the matching grooves of the first pulley 25 and the second pulley 26, thereby limiting the position of the first memory alloy elastic wire 4 and preventing tangling.

[0082] Of course, in the embodiments provided in the present disclosure, the first memory alloy elastic wire 4 and the second memory alloy elastic wire 7 are respectively wound around the first pulley 25 and the second pulley 26 as an example for explanation. In fact, in other embodiments, the first memory alloy elastic wire 4 can also be wound around some of the pulleys included in the second bracket 2, while the second memory alloy elastic wire 7 is wound around another part of the pulleys included in the second bracket 2, that is, the first memory alloy elastic wire 4 and the second memory alloy elastic wire 7 are respectively wound around different pulleys; in some other embodiments, the first memory alloy elastic wire 4 is wound around some of the pulleys included in the second bracket 2, while the second memory alloy elastic wire 7 is wound around some of the pulleys included in the second bracket 2, and the same pulley can be wound with the first memory alloy elastic wire 4 and the second memory alloy elastic wire 7 at the same time (such as the first memory alloy elastic wire 4 is wound around the upper half of the same pulley, and the second memory alloy elastic wire 7 is wound around the lower half). It should be noted that when any one or more pulleys are only used to wind the first memory alloy elastic wire 4, the any one or more pulleys can also be rotatably connected to the first bracket 1.

[0083] In the above technical solution, the length of the first memory alloy elastic wire 4 can be determined based on the movement stroke of the first mounting portion 11 and the second mounting portion 21 when they approach each other, while the length of the second memory alloy elastic wire 7 can be determined based on the movement stroke of the buckle 5 when the limit is released. In one embodiment, since the abutment between the buckle 5 and the first mounting portion 11 only requires a certain contact area, the limit can be released when the buckle 5 rotates a small angle, while the first mounting portion 11 and the second mounting portion 21 need to move a larger stroke before the drive assembly 100 can switch to the compressed state. Therefore, the length of the first memory alloy elastic wire 4 can be set to be greater than the length of the second memory alloy elastic wire to meet the relationship between the movement stroke when the first mounting portion 11 and the second mounting portion 21 approach each other and the movement stroke of the buckle 5 when the limit is released.

[0084] Regarding the installation and fixation of the second memory alloy elastic wire 7 in the above-mentioned embodiments, in one embodiment, the second bracket 2 may include a first mounting column 27, the buckle 5 may include a second mounting column 53, the second mounting column 53 may be connected to the rotating part 51, one end of the second memory alloy elastic wire 7 may be fixedly connected to the first mounting column 27, and the other end may be fixedly connected to the second mounting column 53, and when the second memory alloy elastic wire 7 is tightened, the second mounting column 53 may provide a force to the rotating part 51 to drive the rotating part 51 to rotate away from the first mounting part 11.

[0085] The second memory alloy elastic wire 7 can be fixedly connected to the first mounting post 27 and the second mounting post 53 or detachably connected. For example, in one embodiment, the second memory alloy elastic wire 7 can be welded to the first mounting post 27 and the second mounting post 53 respectively. In another embodiment, the first mounting post 27 and the second mounting post 53 are fixedly connected by stamping.

The first mounting post 27 and the second mounting post 53 are then stamped to fix the second memory alloy elastic wire 7 to the first mounting post 27 and the second mounting post 53 respectively.

[0086] Similarly, regarding the installation and fixation of the first memory alloy elastic wire 4, in one embodiment, the second bracket 2 may include a third mounting post 28, and the first bracket 1 may include a fourth mounting post 12. One end of the first memory alloy elastic wire 4 may be connected to the third mounting post 28, and the other end may be connected to the fourth mounting post 12. The position of the third mounting post 28 on the second bracket 2 and the position of the fourth mounting post 12 on the first bracket 1 may be designed to generate a force that pushes the first mounting portion 11 and the second mounting portion 21 toward each other when the first memory alloy elastic wire 4 is tightened.

For example, the first memory alloy wire 4 and the second memory alloy wire 7 each comprise a nickel-titanium alloy wire. The nickel-titanium alloy wire has the characteristic that when the temperature rises, the nickel-titanium alloy wire contracts and maintains its contraction. When the temperature drops, the nickel-titanium alloy wire can be stretched back to its original length.

A portion of the compression spring may be sleeved on the guide column 211, so that the deformation direction of the compression spring can be limited by the guide column 211 to prevent the compression spring from deforming in a direction deviating from the first direction. Of course, the length of the guide column 211 in the first direction should be set relatively short to prevent the guide column 211 from interfering with the movement between the first mounting portion 11 and the second mounting portion 21 when the drive assembly 100 switches to a compressed state. Here, the second mounting portion 21 includes the guide column 211 as an example for explanation. In other embodiments, the first mounting portion 11 may also include the guide column 211, and the present disclosure does not limit this. Similarly, the second elastic member 6 may also include a compression spring, and the second bracket 2 or the buckle 5 may also include a guide column 211.

[0089] In each of the above embodiments, the first bracket 1 may further include a mounting slot 13, and the drive assembly 100 may further include a first magnet 8. The first magnet 8 may be disposed in the mounting slot 13. When the drive assembly 100 is configured to a corresponding electronic device, the first magnet 8 may interact with a paired magnet included in a corresponding component on the electronic device to generate a repulsive force or an adsorption force acting on the corresponding component on the electronic device, thereby changing the state of the electronic device. This embodiment will be described in detail in conjunction with the electronic device later. The drive assembly 100 may include a single or multiple first magnets 8. When the drive assembly 100 includes multiple first magnets 8, the multiple first magnets 8 may be arranged according to a certain polarity pattern, such as the N pole and S pole of two adjacent first magnets 8 being arranged opposite each other.

The first magnet 8 included in the driving assembly 100 may be provided on the first bracket 1, and the second device body 202 may include a second magnet (not shown). The first memory alloy elastic wire 4 in the driving assembly 100 is in a tightened state, so that the first mounting portion 11 and the second mounting portion 21 move along the first direction and approach each other to the first target position, so that when the driving assembly 100 switches to a compressed state, the first magnet 8 and the second magnet are arranged relative to each other and can interact to generate a repulsive force for driving the first device body 201 and the second device body 202 to rotate relative to each other, so that the first device body 201 and the second device body 202 switch to an expanded state, from Figure 5The state shown by the solid line is switched to the state shown by the dotted line. Of course, in the process of the electronic device 200 being completely switched to the unfolded state shown by the dotted line, other motor components can be set to drive the rotating shaft 22L to rotate; the second device body 202 can also include a third magnet (not shown). The first memory alloy elastic wire 4 in the driving component 100 is in a relaxed state. Under the action of the first elastic member 3, the first mounting portion 11 and the second mounting portion 21 move away from each other to the second target position. When the driving component 100 is switched to the pop-up state, the first magnet 8 and the third magnet are arranged relative to each other, and interact with each other to generate an adsorption force for adsorbing the first device body 201 and the second device body 202, so that the first device body 201 and the second device body 202 remain in a folded state, that is, they can be maintained at Figure 5 The state shown by the solid line.

[0092] Of course, this description is based on the example of the first mounting portion 11 and the second mounting portion 21 approaching each other to the first target position, the first magnet 8 and the second magnet interacting to drive the first device body 201 and the second device body 202 to rotate relative to each other to unfold when the driving assembly 100 is in the compressed state, and the first mounting portion 11 and the second mounting portion 21 move away from each other to the second target position, and the first magnet 8 and the third magnet interacting to maintain the folded state between the first device body 201 and the second device body 202 when the driving assembly 100 is in the ejected state. In other embodiments, the first mounting portion 11 and the second mounting portion 21 may approach each other to the first target position, the first magnet 8 and the second magnet interacting to maintain the folded state between the first device body 201 and the second device body 202 when the driving assembly 100 is in the compressed state, and the first mounting portion 11 and the second mounting portion 21 move away from each other to the second target position, and the first magnet 8 and the third magnet interacting to drive the first device body 201 and the second device body 202 to rotate relative to each other to unfold when the driving assembly 100 is in the ejected state. In this embodiment, the first magnet 8 is provided on the first bracket 1, and the second bracket 2 is fixedly connected to the first device body 201 as an example for explanation. In other embodiments, the first magnet 8 can also be provided on the second bracket 2, and the first bracket 1 can be fixedly connected to the first device body 201.

Similarly, mounting holes may be formed on the first bracket 1 and the second bracket 2, respectively, and a locking member may pass through the mounting hole to lock the first bracket 1 and the third device body 301, and another locking member may pass through the mounting hole to lock the second bracket 2 and the fourth device body 302, so that when the first mounting portion 11 and the second mounting portion 21 approach each other and the driving component 100 switches to a compressed state, the third device body 301 and the fourth device body 302 approach each other, and the overlapping area gradually increases, so as to move from Figure 7 The status shown switches to Figure 6 The state shown; when the first mounting portion 11 and the second mounting portion 21 are away from each other and the drive assembly 100 is switched to the eject state, the third device body 301 and the fourth device body 302 are away from each other, and the overlapping area gradually decreases to Figure 6 The status shown switches to Figure 7 In the state shown, part of the fourth device body 302 protrudes from the third device body 301, so that electronic structures such as a flash, a camera, and an infrared sensor can be set in the non-overlapping area between the third device body 301 and the fourth device body 302.

[0094] The present disclosure also provides a Figure 8 and Figure 9 The electronic device 400 shown in the figure may include a shell 401 and a camera assembly 402.

Figure 8 The status shown switches to Figure 9 When the first mounting portion 11 and the second mounting portion 21 are away from each other and the drive assembly 100 is switched to the pop-up state, the camera assembly 402 can extend through the mating port 401 of the housing, and the electronic device 400 can be moved from the housing 401. Figure 9 The status shown switches to Figure 8The state shown can prevent the camera component 402 from occupying the display area of ​​the electronic device 400, which is beneficial to improving the screen-to-body ratio.

[0095] It should be noted that in Figure 6 The electronic device 200 and Figure 7 、 Figure 8 The electronic device 300 shown may also include a camera component 402, which can be set in any device body of the electronic device 200 and the electronic device 300, and the corresponding driving component 100 for driving the camera component 402 can be set in the same device body to push the camera component 402 to extend out of the corresponding device body or retract into the corresponding device body.
