[0001] This utility model relates to the field of connecting devices, and in particular to a spring-loaded device and an electronic device using the spring-loaded device. Background Technology

[0002] With the rapid development of electronic devices, foldable electronic devices have attracted widespread attention due to their portability. However, these devices typically require users to apply considerable external force to manually open the device, making operation inconvenient. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a spring-loaded opening device disposed on a first body of an electronic device, wherein the first body and a second body of the electronic device are closably connected. The spring-loaded opening device includes:

[0004] A base having a seat body, the seat body including a first end and a second end, the second end being opposite to the first end in the length direction of the seat body;

[0005] The displacement component includes:

[0006] A support member is disposed on the base body, and the support member has a first protrusion, which is disposed at the second end of the base body;

[0007] A first limiting component is disposed on the carrier and the base;

[0008] A recovery component is provided on the carrier and the base;

[0009] An elastic conductive element, wherein a first end of the elastic conductive element is connected to a first end of the base body, and a second end of the elastic conductive element is connected to the first protrusion;

[0010] A first magnetic element is disposed on one side of the carrier.

[0011] In one embodiment of the spring-opening device of the present invention, the displacement component further includes a second limiting component, and the recovery component is located between the first limiting component and the second limiting component.

[0012] In one embodiment of the spring-opening device of the present invention, both the first limiting component and the second limiting component include a limiting structure and a fixing element. The fixing element is connected to the base and the limiting structure is movably disposed on the base.

[0013] In one embodiment of the spring-opening device of this utility model, the recovery component further includes:

[0014] A second protrusion located on the support member;

[0015] An elastic element, one end of which is connected to the second protrusion, and the other end of which is connected to a third protrusion of the seat body;

[0016] In one embodiment of the spring-opening device of the present invention, the displacement component further includes a sliding device, which is fixedly disposed on the first protrusion, and the second end of the elastic conductive element surrounds the sliding device.

[0017] In one embodiment of the spring-opening device of the present invention, the sliding device further includes a first positioning part, which is adapted to and connected to a second positioning part on the first protrusion.

[0018] In one embodiment of the spring-loaded device of this utility model, the elastic conductive element is a shape memory metal wire alloy with an insulating layer, and the shape memory metal wire alloy is arranged along the length direction parallel to the base body.

[0019] In one embodiment of the spring-opening device of this utility model, the shape of the memory metal wire alloy is U-shaped or straight.

[0020] In one embodiment of the spring-opening device of this utility model, the first magnetic element is a multi-stage magnet. The multi-stage magnet is long and strip-shaped, and its magnetism consists of multiple N-stage and S-stage segments arranged alternately along the length of the magnet. The multi-stage magnet is fixedly disposed on the side wall of the support member along the length of the base.

[0021] In one embodiment of the spring-opening device of this utility model, the restoring force of the elastic element is greater than the frictional force between the bearing element and the seat and less than the contraction force of the elastic conductive element.

[0022] In one embodiment of the spring-opening device of this utility model, the length of the elastic conductive element that contracts after being energized is greater than or equal to the distance between adjacent magnetic poles of the multi-stage magnetized magnet.

[0023] This utility model also provides an electronic device, including a first body, a second body, and at least one of the aforementioned spring-opening devices. The spring-opening device is disposed on the first body, and the first body and the second body are closable. A second magnetic element corresponding to the spring-opening device is disposed on the second body. When the first body and the second body are closed, the first magnetic element and the second magnetic element at least partially overlap and attract each other. When the elastic conductive element is energized, it deforms, causing the first magnetic element to displace in the length direction of the base. As a result, the first magnetic element and the second magnetic element repel each other, thus springing open the second body.

[0024] In one embodiment of the electronic device described in this utility model, a pressure sensor and a microcontroller are further included. The microcontroller is connected to the pressure sensor and the elastic conductive element. The pressure sensor is disposed on the first body or the second body and located near the second magnetic element.

[0025] In one embodiment of the electronic device described in this utility model, the pressure sensor is used to sense a tapping action near its location. The pressure sensor converts the tapping action into a tapping signal and transmits the tapping signal to the microcontroller. The microcontroller outputs a control signal to the elastic conductive element according to the tapping signal and energizes the elastic conductive element to cause it to deform.

[0026] The present invention discloses a pop-up device and electronic device. The displacement component includes a support member, a first limiting member, a recovery member, and an elastic conductive member. By energizing the elastic conductive member, the elastic conductive member is deformed, which in turn causes the first magnetic member located on the support member to be displaced. This changes the magnetic relationship between the first magnetic member and the second magnetic member to repulsion, and pops up the second body where the second magnetic member is located. By energizing the elastic conductive member of the pop-up device, the second body of the electronic device can be popped up without manual opening, making it convenient to operate.

Figures 1 to 4 , Figure 1 A schematic diagram of the spring-opening device in one embodiment of this utility model is shown. Figure 2 An exploded view of the spring-loaded device in one embodiment of this utility model is shown. Figure 3A A schematic diagram illustrating the state of the spring-loaded device before it is powered on in one embodiment of this utility model. Figure 3B A schematic diagram illustrating the state of the pop-up device after it is powered on in one embodiment of this utility model. Figure 4 A schematic diagram of an electronic device according to an embodiment of the present invention is shown. The present invention proposes a spring-opening device 10, disposed on a first body 110 of the electronic device. The first body 110 and the second body 120 of the electronic device are closable. The spring-opening device 10 includes a base 1, a displacement component 2, and a first magnetic component 3. The base 1 has a seat 11 and a first end 12 and a second end 13 of the seat 11. The displacement component 2 further includes a support component 21, a first limiting component 22, a recovery component 23, and an elastic conductive component 24. The second end 13 of the seat 11 is opposite to the first end 12 of the seat 11 in the length direction x. The support component 21 is disposed on the seat 11. 21 has a first protrusion 211, which is disposed at the second end 13 of the base 11; a first limiting component 22 is disposed on the support member 21 and the base 11, and is used to limit the displacement of the support member 21 in the length direction x of the base; a restoring component 23 is disposed on the support member 21 and the base 11, and is used to restore the displacement of the support member 21 in the length direction x of the base; the first end 241 of the elastic conductive member 24 is connected to the first end 12 of the base 11, and the second end 242 of the elastic conductive member 24 is connected to the first protrusion 211; a first magnetic member 3 is disposed on one side of the support member 21; as shown Figure 3BAs shown, when the elastic conductive element 24 is energized, it deforms and drives the first magnetic element 3 to move along the length x of the base body via the first protrusion 211 (in one embodiment, the elastic conductive element 24 contracts when energized, and the elastic conductive element 24 drives the first magnetic element 3 to move towards the first end 12 of the base body 11 along the length x of the base body via the first protrusion 211). Then, the displacement of the first magnetic element 3 along the length x of the base body is limited by the first limiting component 22, thereby causing the first magnetic element 3 to repel the second magnetic element 4 disposed on the second body 120 and bounce away from the second body 120; after the elastic conductive element 24 is de-energized, it returns to its original state, and the first magnetic element 3 is reset by the restoring component 23 (e.g., Figure 3A As shown, the recovery component 23 drives the carrier 21 to move towards the second end 13 of the base 11 in the length direction x of the base body, and the first limiting component 22 limits the carrier 21 in the length direction x of the base body. By energizing the elastic conductive element 24 of the pop-up device 10, the second body 120 of the electronic device can be popped open, which is more convenient than manually opening the second body 120 of the electronic device.

[0084] In one embodiment, the displacement component 2 further includes a second limiting component 25, and the recovery component 23 is located between the first limiting component 22 and the second limiting component 25. With this configuration, when the elastic conductive element 24 is energized and deforms, causing the carrier component 21 to displace, and when the elastic conductive element 24 is de-energized and the recovery component 23 resets the carrier component 21, the two limiting components located on both sides of the carrier component 21 jointly limit the travel of the carrier component 21. This avoids displacement relative to the width direction y of the seat caused by uneven force applied to the carrier component 21 after the elastic conductive element 24 deforms. Compared to having only one limiting component, this also increases the stability of limiting the travel of the carrier component 21.

[0085] In one embodiment, both the first limiting component 22 and the second limiting component 25 include limiting structures 221 and 251 and fixing elements 222 and 252. The fixing elements 222 and 252 are connected to the base 11 and movably mount the limiting structures 221 and 251 onto the base 11. The limiting structures 221 and 251 can be recessed limiting grooves, baffles, or protruding limiting blocks. The fixing elements 222 and 252 can be screws, rivets, or buckles. For example, the limiting structure and the fixing element are coupled in such a way that the screw passes through the limiting groove on the carrier 21 and is threadedly connected to the mounting hole of the base 11. A gap is left between the screw and the surface of the limiting groove to facilitate the movement of the carrier 21 on the base 11. Alternatively, a baffle and screw combination can be used. The first limiting component 22 and the second limiting component 25 can also use different combinations of limiting structures and fixing elements. The limiting structures 221 and 251 and the fixing elements 222 and 252 can also be magnetic limiting devices or elastic limiting devices. This utility model is not limited to these. Through the cooperation of the limiting structure and the fixing element, the movement of the bearing member 21 in the length direction x of the seat body can be limited, and the movement of the bearing member 21 in the thickness direction z of the seat body can be restricted.

[0086] In one embodiment, the recovery component 23 further includes a second protrusion 232 and an elastic member 231. The second protrusion 232 is located on the support member 21. One end of the elastic member 231 is connected to the second protrusion 232, and the other end of the elastic member 231 is connected to a third protrusion 14 of the seat 11. Further, in one embodiment, the other end of the elastic member 231 is connected to the third protrusion 14 of the seat 11, and the other end of the elastic member 231 and the third protrusion 14 are fixed by a fixing element. In one embodiment, the elastic member 231 can be a spring, an elastic rubber member, a silicone elastic member 231, etc., and this invention is not limited to these. The displacement of the support member 21 is reset by the restoring force of the elastic member 231, resulting in a simple structure.

[0087] In one embodiment, the displacement component 2 further includes a sliding device 26, which is fixedly disposed on the first protrusion 211, and the second end 242 of the elastic conductive element 24 surrounds the sliding device 26. In one embodiment, the sliding device 26 can be a pulley, a slide rail, or other similar device, but is not limited thereto. Because the second end 242 of the elastic conductive element 24 surrounds the sliding device 26, when the elastic conductive element 24 is energized, it deforms and contracts. The sliding device 26 reduces sliding friction, better transmitting the contractile force of the elastic conductive element 24 to the support member 21 and causing the support member 21 to move.

[0088] In one embodiment, the sliding device 26 further includes a first positioning part 261, and the first protrusion 211 further includes a second positioning part 2111, with the first positioning part 261 and the second positioning part 2111 being adapted and connected. Specifically, in one embodiment, the first positioning part 261 is a "T"-shaped groove positioning member, and the second positioning part 2111 is a "T"-shaped protruding positioning member, or the first positioning part 261 is a "T"-shaped protruding positioning member, and the second positioning part 2111 is a "T"-shaped groove positioning member, with the protruding positioning member and the groove positioning member being adapted and connected. In this way, when the elastic conductive member 24 applies force to the sliding device 26, it can prevent the sliding device 26 from rotating under the force.

[0089] In one embodiment, the elastic conductive element 24 is a shape memory metal wire alloy with an insulating layer. The shape memory metal wire alloy is arranged along the length direction x parallel to the base body, and the shape of the shape memory metal wire alloy is U-shaped or straight. The elastic conductive element 24 is a shape memory metal wire alloy, which has a smaller thickness, which is beneficial to the internal space layout of the spring-loaded device 10, and also helps to reduce the overall thickness of the spring-loaded device 10.

[0090] In one embodiment, the first magnetic element 3 is a multi-stage magnet. The multi-stage magnet is elongated and has multiple N-stage and S-stage magnets arranged alternately along its length. The multi-stage magnet is fixedly mounted on the side wall of the support member 21 along the length x of the base. In one embodiment, the multi-stage magnet is a single unit. Compared to an elongated magnetic element composed of multiple N-stage and S-stage magnet blocks, a single multi-stage magnet eliminates the need to combine and fix multiple N-stage and S-stage magnet blocks, thus avoiding the problem of misalignment between multiple magnet blocks in the thickness direction of the spring-loaded device 10.

[0091] In one embodiment, the restoring force of the elastic element 231 is greater than the frictional force between the support element 21 and the seat 11 and less than the contraction force of the elastic conductive element 24. In another embodiment, the restoring force of the elastic element 231 is greater than the static frictional force between the support element 21 (including the components on the support element 21) and the seat 11. Specifically, in one embodiment, the restoring force of the elastic element 231 is 2N, and the maximum stroke of the elastic element 231 is 30 mm. Further, in one embodiment, the restoring force of the elastic element 231 is greater than the sum of the weights of the support element 21 and the components on the support element 21 and less than the contraction force of the elastic conductive element 24. Since the static frictional force between the support element 21 (including the components on the support element 21) and the seat 11 is less than the weight of the support element 21 (including the components on the support element 21), this setting of the restoring force of the elastic element 231 ensures that the support element will not fail to reset due to metal fatigue or other reasons, and also accelerates the reset speed of the support element 21.

[0092] Please see Figure 5 , Figure 5A schematic diagram illustrating the length change of the elastic conductive element before and after energization in one embodiment of the present invention is shown. In one embodiment, the length L2 of the elastic conductive element 24 after energization is greater than or equal to the distance L1 between adjacent like magnetic poles of the multi-stage magnetized magnet. When the elastic conductive element 24 is not energized, the magnetic poles of the first magnetic element 3 and the second magnetic element 4 are in a state of attraction between opposite poles. Figure 5 The direction indicated by the middle arrow shows the state of the spring-loaded device after the elastic conductive element is energized. When the elastic conductive element 24 is energized, it contracts and causes the bearing element 21 to shift along the length x of the base. The distance the bearing element 21 moves is greater than or equal to the distance L1 between adjacent like magnetic poles of the multi-stage magnetized magnets. Then, all the magnetic poles of the first magnetic element 3 and the second magnetic element 4 are in a state of repulsion due to their like poles, thus repelling the first magnetic element 3 and the second magnetic element 4. Because the displacement of the bearing element 21 is caused by the contraction of the elastic conductive element, the length L2 of the contraction of the elastic conductive element must be greater than or equal to the distance L1 between the like magnetic poles. Specifically, in one embodiment, the length of the elastic conductive element 24 after being energized is greater than or equal to 2.8 mm, the spacing between adjacent like magnetic poles of the multi-level magnetized magnet is 2.8 mm, and the surface magnetic field of the multi-level magnetized magnet is 4320 Gs ± 200 Gs. In practical applications, the length L2 of the elastic conductive element 24 after being energized, the spacing L1 of the like magnetic poles, and the surface magnetic field of the multi-level magnetized magnet can be set according to the weight of the first body 110 and the second body 120. This utility model is not limited thereto.

[0093] Please see Figure 4 This utility model also provides an electronic device 100, including a first body 110, a second body 120, and at least one of the aforementioned spring-loaded devices 10. The spring-loaded device 10 is disposed on the first body 110. The first body 110 and the second body 120 are closable. A second magnetic element 4 corresponding to the spring-loaded device 10 is disposed on the second body 120. When the first body 110 and the second body 120 are closed, the first magnetic element 3 and the second magnetic element 4 at least partially overlap and attract each other. When the elastic conductive element 24 is energized, it deforms, causing the first magnetic element 3 to displace in the length direction x of the body. Consequently, the first magnetic element 3 and the second magnetic element 4 repel each other, thus springing the second body 120 open. In one embodiment, the two spring-loaded devices 10 are respectively disposed at the lower left and lower right corners of the first body 110, and the two second magnetic elements 4 are correspondingly disposed on the first body 110. This symmetrical arrangement of the elastic devices is beneficial for applying uniform force to spring open the second body 120, especially when the size and weight of the second body 120 are large. The second body 120 of the electronic device 100 can be opened by energizing the elastic conductive element 24 of the opening device 10, which is more convenient than manually opening the second body 120 of the electronic device 100.

[0094] Please see Figure 4 and Figure 6 , Figure 6A schematic block diagram illustrating the operation of the pop-up device in one embodiment of the present invention is shown. In one embodiment, it further includes a pressure sensor 130 and a microcontroller 140. The microcontroller 140 is connected to the pressure sensor 130 and the elastic conductive element 24. The pressure sensor 130 is disposed on the first body 110 or the second body 120 and located near the second magnetic element 4. When the pressure sensor 130 senses the pressure action of the first body 110 or the second body 120 in its vicinity, the pressure sensor 130 transmits the pressure action electrical signal to the microcontroller 140. The microcontroller 140 controls the elastic conductive element 24 to be energized, and pops up the second body 120. The pressure sensor 130 can be used in conjunction with elements such as buttons, or can directly sense pressure action. In this way, the pressure sensor 130 can trigger the pop-up device (10, 20, 30) to work and pop up the second body 120 of the electronic device 100 according to the sensed pressure action, thereby enhancing the operability of the electronic device 100. Furthermore, in one embodiment, the microcontroller 140 is connected to the pressure sensor 130 and the power amplifier 150, the power amplifier 150 being connected via a power interface 5 (… Figure 6 (Not shown) is connected to the pop-out device 10, and the power supply 160 supplies power to the microcontroller 140 and the power amplifier 150. When the first body 110 or the second body 120 near the pressure sensor 130 is struck, the pressure sensor 130 senses the striking action and converts it into an electrical signal (striking signal) which is transmitted to the microcontroller 140. The microcontroller 140 amplifies the power signal (control signal) to the pop-out device 10 through the power amplifier 150 and transmits it to the pop-out device 10. The elastic conductive element 24 of the pop-out device 10 deforms and contracts, causing the first magnetic element 3 to displace in the length direction x of the seat. As a result, the first magnetic element 3 and the second magnetic element 4 repel each other, popping the second body 120 open. It should be noted that when there are two or more pop-up devices 10, the pressure sensor 130 can be a single sensor (located near the plurality of second magnetic elements 4, for example, in the middle of two second magnetic elements 4). When the microcontroller 140 receives a tapping signal from the pressure sensor 130, it simultaneously sends a signal to all pop-up devices 10 and pops up the second body 120. Alternatively, there can be multiple pressure sensors 130 located near the plurality of second magnetic elements 4. When the microcontroller 140 receives a tapping signal from the pressure sensor 130, it simultaneously sends a signal to all pop-up devices 10 and pops up the second body 120. Using a tapping method to activate the pop-up device 10 and pop up the second body 120 of the electronic device 100 provides a simple and convenient control method for opening the second body 120 of the electronic device 100.

[0095] The present invention discloses a pop-up device and electronic device. The displacement component includes a support member, a first limiting member, a recovery member, and an elastic conductive member. By energizing the elastic conductive member, the elastic conductive member is deformed, which in turn causes the first magnetic member located on the support member to be displaced. This changes the magnetic relationship between the first magnetic member and the second magnetic member to repulsion, and pops up the second body where the second magnetic member is located. By energizing the elastic conductive member of the pop-up device, the second body of the electronic device can be popped up without manual opening, making it convenient to operate.
