[0024] Combine the following Figures 1 to 7A lift mechanism 100 and an electronic device 200 according to an embodiment of the present application are described.

[0025] like Figure 1 As shown, according to some embodiments of the present application, the push rod mechanism 100 includes: a wheel body 106, a rod body 112 and a driving member 116. The wheel body 106 includes a slot body 108; one end of the rod body 112 is slidably connected to the slot body 108; the driving member 116 is connected to the wheel body 106, and the driving member 116 is used to drive the wheel body 106 to rotate, and the rotation of the wheel body 106 drives the rod body 112 to reciprocate along the slot body 108 between the first position and the second position.

[0026] In an embodiment of the present application, the push rod mechanism 100 includes a wheel body 106, a rod body 112 and a driving member 116. The wheel body 106 is provided with a groove body 108 that cooperates with the rod body 112. When the driving member 116 drives the wheel body 106 to rotate, it can drive the rod body 112 to slide along the groove body 108, thereby driving the rod body 112, so that the rod body 112 reciprocates between the first position and the second position.

[0027] Furthermore, the groove 108 of the wheel 106 provides guidance for the movement of the rod 112. When the wheel 106 rotates, the end of the rod 112 that matches the groove 108 moves along the extension track of the groove 108. The wheel 106 provides a carrier for the groove 108. The groove 108 is provided on the wheel 106 to guide the movement of the rod 112. The driving member 116 is connected to the wheel 106. The driving member 116 provides power for the rotation of the wheel 106. The wheel 106 is driven by the driving member 116, and the rod 112 is driven to move along the groove 108 during the rotation of the wheel 106.

[0028] Specifically, when the rod body 112 is in the first position, the rod body 112 is in an initial state, that is, the driving member 116 does not drive the wheel body 106 to rotate; when the rod body 112 is in the second position, that is, the driving member 116 drives the wheel body 106 to rotate, thereby driving the rod body 112 to move from the first position to the second position; when the driving member 116 drives the wheel body 106 to rotate in the opposite direction, the rod body 112 moves from the second position back to the first position.

[0029] The push rod mechanism 100 in the embodiment of the present application drives the wheel body 106 to rotate through the driving member 116, driving the rod body 112 to slide along the groove body 108 of the wheel body 106, so that the other end of the rod body 112 extends or retracts, thereby realizing mechanical transmission between the various components in the push rod mechanism 100. Compared with the related art in which the electric motor drives the two magnetic suction cups to attract or repel each other, the structure is simple and cost-saving.

[0030] like Figure 1 , Figure 3, Figure 5 As shown, in some embodiments of the present application, the groove body 108 includes a spiral groove body.

[0031] Specifically, by setting the groove body 108 to a spiral groove body, the end of the rod body 112 slides along the spiral direction of the spiral groove body during the rotation of the wheel body 106, thereby ensuring the smooth sliding of the rod body 112 and the operation of the mechanical transmission of the push rod mechanism 100, avoiding the occurrence of jamming and the like, improving the mechanical transmission efficiency of the push rod mechanism 100, and enhancing the user experience.

[0032] Specifically, the spiral groove is formed on the surface of the wheel body 106 . By forming the groove on the surface of the wheel body 106 , it is easier to process and assemble.

[0033] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the wheel body 106 rotates along the first direction a, driving the rod body 112 to move from the first position to the second position; Figure 5 and Figure 6 As shown, when the wheel body 106 rotates along the second direction b, it drives the rod body 112 to move from the second position to the first position.

[0034] In some embodiments, Figure 3 and Figure 4 As shown, the wheel body 106 rotates along the first direction a, driving the rod body 112 to slide along the groove body 108, so that the other end of the rod body 112 extends out of the opening 104. By driving the wheel body 106 to rotate an angle, one end of the rod body 112 slides along the spiral groove body, and the other end of the rod body 112 pushes out of the opening 104 and protrudes outside the housing, that is, the rod body 112 is in the second position for mechanically opening the folding device.

[0035] like Figure 5 and Figure 6 As shown, the wheel body 106 rotates along the second direction b, driving the rod body 112 to slide along the groove body 108, so that the other end of the rod body 112 retracts into the opening 104. The first direction a and the second direction b are opposite. When the wheel body 106 rotates along the second direction b, the rod body 112 slides from the second position to the first position along the spiral groove body, that is, the rod body 112 is reset. The present application realizes a push rod mechanism that only needs to set a small distance, occupies a small space, and is more conducive to improving the design of folding products.

[0036] In some embodiments of the present application, the slot body 108 includes an arc-shaped slot body. By setting the slot body 108 as an arc-shaped slot body, the sliding cooperation between the rod body 112 and the arc-shaped slot body is smoother, thereby improving the stability of the device operation.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the driving member 116 includes: a shape memory alloy member 118, the shape memory alloy member 118 is connected to the wheel body 106; a reset member 120, one end of the reset member 120 is connected to the wheel body 106; wherein the shape memory alloy member 118 is used to drive the wheel body 106 to rotate by deformation, driving the rod body 112 to move from the first position to the second position along the groove body 108; when the shape of the shape memory alloy member 118 is restored, the reset member 120 drives the wheel body 106 to rotate, driving the rod body 112 to move from the second position to the first position.

[0038] Specifically, the shape memory alloy part 118 is connected to the wheel body 106 to drive the wheel body 106 to rotate. One end of the reset part 120 is connected to the wheel body 106, and the reset part 120 can drive the wheel body 106 to automatically reset, thereby avoiding manual reset by the user and improving the user experience. Compared with the magnetic suction parts in the related art, the push rod mechanism 100 of the present application replaces the driving method of the motor through the characteristics of the shape memory alloy part. The implementation form is simple, the cost is low, and the space occupied and the activity space are small. It can improve the space utilization rate of the push rod mechanism 100 in the electronic device, realize the reasonable allocation of space resources, improve the stacking characteristics of the electronic device, and improve the user experience.

[0039] At the same time, there is no noise generated by the motor drive, no noise interference, and the user experience is improved. Furthermore, it replaces the magnetic suction parts and motors in the prior art, does not interfere with other components, and improves the stability of the operation of electronic equipment.

[0040] Specifically, Figure 3 and Figure 4 As shown, the driving member 116 also includes a driving circuit, and the shape memory alloy member 118 is electrically connected to the driving circuit. The driving circuit provides an electric connection path for the shape memory alloy member 118. After the shape memory alloy member 118 is powered on, the temperature of the shape memory alloy member 118 rises, shrinks and deforms, so as to drive the wheel body 106 to rotate along the first direction a; Figure 5 and Figure 6 As shown, when the shape memory alloy member 118 is powered off, its shape is restored to the shape before the power is turned on, and the reset member 120 drives the wheel body 106 to rotate along the second direction b.

[0041] like Figure 7 As shown, in some embodiments of the present application, the driving circuit includes a switch key 122, which is connected in series with the shape memory alloy member 118 to control the shape memory alloy member 118 to be powered on or off.

[0042] Specifically, the shape memory alloy 118 can be powered on by controlling the switch key 122, so that the shape memory alloy 118 drives the wheel 106 to rotate along the first direction a, so that the rod 112 extends out of the opening 104; or, the shape memory alloy 118 can be powered off by controlling the switch key 122, so that the shape memory alloy 118 restores its shape, and the reset member 120 resets at the same time, driving the shape memory alloy 118 to drive the wheel 106 to rotate along the second direction b, so that the rod 112 retracts into the opening 104. Compared with the mutual attraction and mutual repulsion between the magnetic attraction member and the electric motor in the related art, the principle is simple, the control is convenient, the response is rapid, the mechanical efficiency and response efficiency of the push rod mechanism 100 can be improved, the convenience of user use is improved, and the user experience is improved.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the reset member 120 includes a spring. When the shape memory alloy member 118 is deformed, the spring is stretched. When the shape memory alloy member 118 is restored to its original shape, the spring is reset to pull the wheel body to rotate in the opposite direction.

[0044] Specifically, the reset member 120 includes a spring. When the shape memory alloy member 118 is deformed, the spring is stretched. When the shape memory alloy member 118 is restored to its previous shape, the spring is reset, driving the wheel body 106 to rotate back to the initial position, and the rod body 112 slides back to the first position along the groove body 108 to achieve reset. At the same time, the spring structure is simple, low in cost, and occupies little space and activity space, which can further reduce the design difficulty and design cost and improve the space utilization rate of the push rod mechanism 100.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the wheel body 106 includes a positioning column 110 , and the shape memory alloy member 118 is connected to the positioning column 110 .

[0046] Specifically, the positioning column 110 provides support for the connection between the wheel body 106 and the shape memory alloy member 118 .

[0047] Specifically, the positioning column 110 is disposed on the wheel body 106 at a side opposite to the extension direction of the rod body 112 , thereby avoiding interference between the positioning column 110 and the rod body 112 when the wheel body 106 rotates, thereby improving the operating stability of the push rod mechanism 100 .

[0048] Specifically, the reset member 120 and the positioning column are arranged on two opposite sides of the wheel body 106, so that when the shape memory alloy member 118 deforms to drive the wheel body 106 to rotate, both opposite sides of the wheel body 106 are subjected to force, thereby ensuring the stability of the rotation of the wheel body 106.

[0049] like Figure 2 As shown, in some embodiments of the present application, the end of the rod body 112 includes a protruding structure 114 , and the protruding structure 114 is slidably connected to the groove body 108 .

[0050] Specifically, the rod body 112 is bent, and can achieve sliding cooperation with the groove body 108 through the protruding structure 114 at the end. By setting the protruding structure 114, a reasonable design of the space occupied by the push rod mechanism 100 can be achieved, so as to reduce the activity space of the push rod mechanism 100 and achieve a reasonable allocation of space resources.

[0051] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments of the present application, the wheel body 106 includes a circular wheel, and the starting point of the spiral groove body is located at the center of the circular wheel.

[0052] Specifically, the wheel body 106 is a round wheel, which has a simple structure, is easy to obtain, and rotates more quickly and labor-savingly. The starting point of the spiral groove is located at the center of the round wheel, and the center of the round wheel remains stationary. By setting the starting point of the groove at the center of the round wheel, the first position of the rod body 112 is also set at the center of the circle. During the rotation of the round wheel, the rod body 112 will slide along the spiral groove from the center of the circle, so that the rotation of the round wheel and the sliding of the rod body 112 along the groove body 108 are carried out simultaneously, avoiding the occurrence of phenomena such as falling out of the groove due to asynchronous movement.

[0053] In some embodiments of the present application, the wheel body 106 may be in the shape of a square wheel body, or a wheel body in other shapes, as long as it can support the trough body 108 and meet the space design requirements.

[0054] In some embodiments of the present application, the invention further includes: a limiting member, wherein the limiting member is located on both sides of the rod body.

[0055] Specifically, the limiting members are located on both sides of the rod body, and are used to limit the shaking of the rod body during the movement of the rod body, so that the rod body can be smoothly extended or retracted, avoiding shaking during the movement and causing jamming.

[0056] In some embodiments of the present application, a housing 102 is further included. The wheel body 106, the rod body 112 and the driving member 116 are all arranged in the housing 102. The housing 102 provides installation space for the wheel body 106 and the driving member 116, and provides protection for the wheel body 106 and the driving member 116. The housing is provided to facilitate the installation of the entire push rod mechanism on the application equipment, so as to facilitate installation.

[0057] Among them, when the rod body 112 is in the first position, the other end of the rod body 112 is located in the shell 102, that is, the driving member 116 does not drive the wheel body 106 to rotate; when the rod body 112 is in the second position, the other end of the rod body 112 extends out of the shell 102, that is, the driving member 116 drives the wheel body 106 to rotate, thereby driving the rod body 112 to move from the first position to the second position. When the driving member 116 drives the wheel body 106 to rotate in the opposite direction, the rod body 112 moves from the second position back to the first position.

[0058] like Figure 7 As shown, according to some embodiments of the present application, the electronic device 200 includes: a first folding body 202, the first folding body includes an opening 104; a second folding body 204, the first folding body 202 is connected to the second folding body 204, and the first folding body 202 and the second folding body 204 can be in a folded state or an unfolded state. When the first folding body 202 and the second folding body 204 are in the folded state, the second folding body 204 covers the opening 104; and a push rod mechanism 100 as in any of the above embodiments, the push rod mechanism 100 is arranged on the first folding body 202, and the other end of the rod body of the push rod mechanism is arranged corresponding to the opening.

[0059] Specifically, when the rod body 112 is in the first position, the other end of the rod body 112 is located in the opening; when the rod body 112 is in the second position, the other end of the rod body 112 extends through the opening 104 to push open the second folding body 204 .

[0060] Specifically, the electronic device 200 includes a first folding body 202, a second folding body 204 and a push rod mechanism 100. The first folding body 202 is rotatably connected to the second folding body 204, and the first folding body 202 and the second folding body 204 can be in a folded state or an unfolded state. The push rod mechanism 100 is arranged on the first folding body 202. When the first folding body 202 and the second folding body 204 are in a folded state, the rod body 112 of the push rod mechanism 100 is in a first position, and the end of the rod body 112 is located in the opening 104; when the first folding body 202 and the second folding body 204 need to be unfolded, the push rod mechanism 100 is triggered to make the rod body 112 move to the second position, and the end of the rod body 112 extends out of the opening 104, thereby pushing the first folding body 202 and the second folding body 204 open, thereby realizing the unfolding of the first folding body 202 and the second folding body 204.

[0061] Furthermore, the opening 104 is located on the folding side opposite to the first folding body 202 and the second folding body 204, and the rod body 112 of the push rod mechanism 100 can be pushed out by the first folding body 202 to realize the unfolding of the first folding body 202 and the second folding body 204 from the folded state. Compared with the magnetic suction parts and electric motors in the related technology, it saves occupied space and activity space, which is beneficial to improve the space utilization rate of the push rod mechanism 100 in the electronic device 200, realizes the reasonable allocation of space resources, and improves the stacking characteristics of the electronic device 200; and does not require motor drive, reduces the noise of the electric motor, avoids interference with other components in the electronic device 200, has a simple structure, reduces design difficulty and design cost, and improves the convenience of users using the electronic device 200, thereby improving the integration of various components in the electronic device 200 and improving the user experience.

[0062] Specifically, the housing 102 of the push rod mechanism 100 can be an integrated housing with the housing of the first folding body 202 , and the opening 104 is opened on the housing of the first folding body 202 , thereby reducing the number of parts and processing procedures.

[0063] Specifically, the other end of the rod 112 is located in the opening 104, and the end is flush with the outer surface of the first folding body 202, thereby ensuring the aesthetic appearance. Further, the cross-sectional shape of the rod 112 is the same as the cross-sectional shape of the opening 104, and the gap between the two is sufficient to allow sliding, so as to ensure that the end of the rod 112 can cover the opening 104 to the maximum extent, so as to ensure stable sliding while ensuring the aesthetic appearance.

[0064] like Figure 7 As shown, the electronic device 200 further includes a rotating portion 206 , through which the first folding body 202 and the second folding body 204 are rotatably connected, and the opening 104 is located at one side of the rotating portion 206 .

[0065] Specifically, the electronic device 200 also includes a rotating part 206, and the first folding body 202 and the second folding body 204 are rotatably connected through the rotating part 206. The opening 104 is located on one side of the rotating part 206. By setting the opening 104 close to the rotating part 206, the first folding body 202 and the second folding body 204 can be pushed open with a small force, thereby eliminating the motor or motor, and the first folding body 202 and the second folding body 204 can be pushed open from the folded state through the push rod mechanism 100.

[0066] like Figure 7 As shown, there are two push rod mechanisms 100 , and the two push rod mechanisms 100 are located at opposite ends of the first folding body 202 .

[0067] Specifically, the push rod mechanisms 100 are symmetrically arranged along the midline of the axis of the rotating part. The two push rod mechanisms 100 can ensure that the first folding body 202 and the second folding body 204 are evenly stressed when unfolded from a folded state, and the movement is more stable. At the same time, it avoids excessive force on one push rod mechanism 100, low mechanical efficiency, and poor activity effect, thereby improving the user experience.

[0068] Furthermore, when two push rod mechanisms 100 are used, the two shape memory alloy parts 118 in the two push rod mechanisms 100 can be connected in series and then connected in series with a switch key, so as to achieve synchronous movement of the two push rod mechanisms 100 controlled by one switch key; or, the two shape memory alloy parts 118 in the two push rod mechanisms 100 can be connected in parallel and then connected in series with a switch key, so as to achieve synchronous movement of the two push rod mechanisms 100 controlled by one switch key. By adopting the parallel connection method, when another shape memory alloy part 118 fails, the other push rod mechanism 100 is still in normal operation, thereby improving the user experience.

[0069] It is understandable that the number and location of the push rod mechanisms 100 can be reasonably adjusted according to the weight and size of the first folding body 202 and the second folding body 204 , and the present application does not impose strict restrictions on the number and location of the push rod mechanisms 100 .

[0070] like Figure 7 As shown, in some embodiments of the present application, a display screen 210 is also included, and the display screen 210 is arranged on the first folding body 202 and the second folding body 204; wherein, when the first folding body 202 and the second folding body 204 are in a folded state, the display screen is in a folded state; when the first folding body 202 and the second folding body 204 are in an unfolded state, the display screen can be in an unfolded state.

[0071] In a specific application, the display screen 210 provides display information for the user. The display screen 210 is arranged on the first folding body 202 and the second folding body 204. The folding or unfolding of the first folding body 202 and the second folding body 204 can realize the folding or unfolding of the display screen 210. By setting a foldable display screen, the user's demand for the use of a large-screen mobile terminal can be met.

[0072] Furthermore, compared with the use of magnetic parts and electric motors in the related art, the electronic device 200 using the push rod mechanism 100 saves occupied space and activity space, which is beneficial to improving the space utilization rate of the push rod mechanism 100 in the electronic device 200, realizing the reasonable allocation of space resources, and improving the stacking characteristics of the mobile terminal 200; and no motor drive is required, which reduces the noise of the electric motor and avoids interference with other components in the electronic device 200.
