Second implementation of the first and second magnets: the first magnet 110 is a radially magnetized cylindrical magnet or a ring magnet, and the second magnet 120 is a radially magnetized cylindrical magnet or a ring magnet. The magnetic poles of the first magnet 110 and the magnetic poles of the second magnet 120 are radially distributed. In the case where the pressing piece 130 is released or fully pressed, the first and second magnets 110 and 120 are aligned as a whole. When the pressing member 130 is released, the magnetic poles of the first and second magnets 110 and 120 are oriented in the same direction, and magnetic attraction between the two magnets is achieved. In the case of full depression of the pressing member 130, the magnetic poles of the first and second magnets 110 and 120 are arranged to face in the same direction, and magnetic repulsion of the two magnets is achieved. The circumferential position of the first magnet 110 is adjusted through a gear rack mechanism, so that the magnetic poles of the first magnet 110 can be reversed, and the first magnet 110 and the second magnet 120 can be switched between a magnetic adsorption state and a repulsion state.

In some embodiments, referring to fig. 1, the gear 152 is pivotally connected to the housing 200 through a connecting shaft 153, the gear 152 is coaxially fixed to the connecting shaft 153, and both ends of the connecting shaft 153 are connected to the housing 200.

In the scheme, the electromagnet comprises an iron core and a coil wound on the iron core, and the energized coil generates a magnetic field. When the pressing piece 130 is not pressed, the second magnet 120 on the cover 300 and the iron core of the electromagnet are magnetically attracted, so that the cover 300 remains closed on the case 200. The trigger switch 154 has a fixed contact and a movable contact, and the trigger switch 154 is connected in a circuit. When the trigger switch 154 is pressed, the movable contact and the fixed contact are conducted, and it is known that the trigger switch 154 is pressed. When the trigger switch 154 is released or not depressed, the movable contacts are reset and the fixed contacts remain separated. Referring to fig. 8, when the pressing member 130 is pressed, the trigger switch 154 is triggered, and then the electromagnet is turned on to generate a magnetic field repulsive to the second magnet 120, so that the cover 300 moves upward by a certain distance with respect to the housing 200.

Illustratively, the second magnet 120 is axially magnetized, i.e., two poles of the second magnet 120 are distributed along the axial direction. Two magnetic poles of the electromagnet are arranged along the predetermined direction of the housing 200, and two magnetic poles of the second magnet 120 are arranged along the thickness direction of the cover 300, so that the electromagnet after being electrified and the second magnet 120 on the cover 300 in the closed state can be magnetically repelled.

In this case, a push rod 155 is provided on the rear surface 130a of the pressing member 130, and the trigger switch 154 is pushed by the push rod 155, so that the trigger switch 154 and the pressing member 130 may be disposed at a certain distance, thereby facilitating formation of a larger space within the housing 200 for disposing the second magnet 120 and the like.

When the push rod 155 is installed, referring to fig. 6 and 7, the housing 200 has a positioning groove 203, the push rod 155 can extend from one end of the positioning groove 203 and move back and forth along the positioning groove 203, and the trigger switch 154 is disposed at the other end of the positioning groove 203, which is convenient for guiding the push rod 155 to move on a predetermined path.

A third trigger implementation is a halbach magnet array. Referring to fig. 9 to 11, the trigger 150 includes a slider 156 disposed opposite to an edge of the back surface 130a of the pressing member 130, one end of the slider 156 facing the pressing member 130 is provided with a guide surface 1561 and/or an edge of the pressing member 130 facing the slider 156 is provided with a guide surface 131; the first magnet 110 is a first halbach magnet array 110a capable of moving on the housing 200 along a predetermined path, one end of the first halbach magnet array 110a is disposed opposite to the slider 156, the other end of the first halbach magnet array 110a is provided with a second elastic member 157, and the second elastic member 157 is used for resetting the first halbach magnet array 110a and the slider 156 when the pressing member 130 is released; the second magnet 120 is a second halbach magnet array 120a; when the pressing member 130 is pressed, the pressing member 130 pushes the slider 156 to move, and the slider 156 pushes the first halbach magnet array 110a to move along a predetermined path.

In this embodiment, the first magnet 110 and the second magnet 120 are provided as a first halbach magnet array 110a and a second halbach magnet array 120a, respectively. Referring to fig. 11, the halbach magnet array is a magnet structure formed by arranging a plurality of magnets in a certain magnetic pole orientation, and is an approximately ideal structure in engineering, and generates the strongest magnetic field with the least amount of magnets. By changing the relative positions of the first halbach magnet array 110a and the second halbach magnet array 120a, it is possible to switch between two states of magnetic attraction and repulsion of the two halbach magnet arrays.

Illustratively, referring to fig. 11, the first halbach magnet array 110a includes four magnets arranged in sequence, and the second halbach magnet array 120a includes six magnets arranged in sequence, with the magnetic poles of each magnet arranged in the direction of the arrow (a) in fig. 11. As shown in fig. 11 (a), there is a very strong magnetic attraction force between the first halbach magnet array 110a and the second halbach magnet array 120a. As shown in fig. 11 (a), the first halbach magnet array 110a is displaced by a certain amount relative to the second halbach magnet array 120a, and there is an extremely strong magnetic repulsive force between the first halbach magnet array 110a and the second halbach magnet array 120a. Of course, the number and arrangement of the magnets in the first halbach magnet array 110a and the second halbach magnet array 120a may have other combinations, and are not limited herein.

When the pressing member 130 is not pressed, the first halbach magnet array 110a is maintained at the initial position by the second elastic member 157, and at this time, both halbach magnet arrays maintain magnetic attraction, so that the cover 300 is maintained closed on the housing 200. In the process that the pressing member 130 is pressed down to move for a certain stroke, the edge of the back surface 130a of the pressing member 130 abuts against one end of the slider 156 to push the slider 156 and the first halbach magnet array 110a to move along a predetermined path, so as to change the relative positions of the two halbach magnet arrays, and the magnetic poles of the first halbach magnet array 110a after moving for the predetermined stroke are set as the magnetic poles of the second halbach magnet array 120a on the cover 300 to be mutually exclusive, so that the cover 300 moves upward for a certain distance relative to the housing 200. The second elastic member 157 is compressed to store energy during the pressing of the pressing member 130, and the second elastic member 157 drives the first halbach magnet array 110a and the slider 156 to be reset when the pressing member 130 is released. The second elastic element 157 may be a spring, a spring plate, or other elastic structure.

There are several implementations where the slider 156 and the pressing member 130 are provided with guide surfaces. Referring to fig. 10, the first implementation is: an end of the slider 156 facing the pressing member 130 is provided with a guide surface 1561. The second implementation mode is as follows: the edge of the pressing piece 130 facing the slider 156 is provided with a guide surface 131. The third implementation mode is as follows: one end of the slider 156 facing the pressing member 130 is provided with a guide surface 1561, and edges of the pressing member 130 facing the slider 156 are each provided with a guide surface 131.

In some embodiments, referring to fig. 10, the first halbach magnet arrays 110a are distributed in pairs on both sides of the pressing member 130, a slider 156 is disposed between each first halbach magnet array 110a and the pressing member 130, and a second elastic member 157 is disposed between each first halbach magnet array 110 a; referring to fig. 9, the second halbach magnet arrays 120a are distributed on the cover 300 in pairs and are disposed in one-to-one correspondence with the first halbach magnet arrays 110 a.

In this scheme, more magnets are arranged in a limited space through the first halbach magnet array 110a and the second halbach magnet array 120a arranged in pairs, and the corresponding sliding block 156 and the second elastic member 157, so as to form stronger magnetic adsorption and mutual repulsion effects. And by pressing the pressing member 130, the two sliding blocks 156 are moved, and the corresponding first halbach magnet array 110a is pushed by the sliding blocks 156 to move along a predetermined path, so as to generate a magnetic force with the corresponding second halbach magnet array 120a.

In some embodiments, referring to fig. 10, each magnet of the first halbach magnet array 110a is movably mounted on the housing 200 along an arc or a straight line.

In this scheme, the moving path of the first halbach magnet array 110a is set to be an arc line or a straight line, so that the relative positions of the first halbach magnet array 110a and the second halbach magnet array 120a can be realized, and the two states can be further adjusted to be switched between a magnetic adsorption state and a mutual exclusion state.

The housing 200 may be provided with a guide slot 204 extending along a predetermined path for the first halbach magnet array 110a and the slider 156 to move. The guide groove 204 may be disposed adjacent to a surface of the housing 200, so that when the pressing member 130 is pressed, the pressing member 130 pushes the slider 156 and the slider 156 pushes the first halbach magnet array 110a to move, and a larger space is formed inside the housing 200 to place other parts.

For the above embodiments, there are different implementations when the first elastic member is disposed. Referring to fig. 2 or fig. 7, the first elastic element 140 is a spring, the back surface 130a of the pressing element 130 has a guiding post 132, one end of the spring is sleeved on the guiding post 132 and abuts against the back surface 130a of the pressing element 130, and the other end abuts against the inner surface of the mounting groove 201. Or, the first elastic element 140 is a spring plate, and two ends of the spring plate respectively abut against the back surface 130a of the pressing element 130 and the inner surface of the mounting groove 201.

In this embodiment, the first elastic member 140 is configured as a spring, a resilient sheet, or other elastic structure, and is disposed between the back surface 130a of the pressing member 130 and the inner surface of the mounting groove 201 in a compressed manner. The pressing member 130 is compressed to store energy when pressed and is extended to release energy when the pressing member 130 is released. Wherein the spring can be limited by the guide post 132 on the pressing member 130. By providing the plurality of first elastic members 140, an elastic force to the pressing member 130 can be increased.

Referring to fig. 1, 6 and 9, an embodiment of the present disclosure provides an apparatus housing, including a housing 200, a cover 300, a rotating shaft 400 and the magnetic opening/closing button 100, wherein the cover 300 is pivotally connected to the housing 200 through the rotating shaft 400, and the magnetic opening/closing button 100 is disposed on the housing 200 and the cover 300.

The device housing may be a smart watch housing capable of accommodating a True Wireless Stereo (TWS) headset, a headset charging box, various wearable device housings, or other device housings having a cover 300 and a housing 200, among others.

The equipment shell that this application embodiment provided, owing to adopt above-mentioned magnetism to inhale formula and open and shut button 100, casing 200 need not to set up and dodge the hole, effectively reduces the dust foreign matter and gets into to dodge the hole and cause to press the possibility of feeling poor or even the dead knot tongue of card, has promoted the reliability. The buckle and the buckle tongue are eliminated, the structure exposed out of the shell 200 is reduced, the product appearance is better, and the sound generated when the cover body 300 is closed is effectively reduced.

When the housing 200 is disposed, referring to fig. 1, the housing 200 may include a metal middle frame 210 and a plastic middle frame 220 disposed on the metal middle frame 210, and the cover 300 and the plastic middle frame 220 are disposed adjacent to each other. In addition, the entire housing 200 may be made entirely of plastic or metal.

In order to enable the cover 300 to be automatically opened, in some embodiments, an energy storage driving assembly is disposed between the housing 200 and the cover 300. When the cover 300 is closed, the energy storage driving assembly stores energy. When the cover 300 is in a free state, the energy storage driving assembly releases energy to drive the cover 300 to open.

There are different implementations when setting the energy storage drive assembly. The first energy storage driving assembly is realized in the following way: the combination of the concave wheel, the cam and the elastic member. The elastic member may be a spring. Illustratively, a first end of the rotating shaft 400 is rotatably mounted in the central hole of the cover 300, and a second end of the rotating shaft 400 is fixed on the housing 200. The cover body 300 has a cam coaxial with the central hole, and an end surface of the cam has an arc-shaped protrusion. The rotating shaft 400 is sleeved with a concave wheel, one end face of the concave wheel is provided with an arc-shaped groove, and the concave wheel is connected with the rotating shaft 400 in a molded surface mode, so that the concave wheel can axially move along the rotating shaft 400 and cannot rotate around the rotating shaft 400. The arc protrusion of the cam and the arc groove of the concave wheel are matched in the axial direction of the rotating shaft 400. The rotating shaft 400 is further sleeved with an elastic member, the elastic member is compressed between the housing 200 and the concave wheel, and the concave wheel is pushed to the cam under the action of the elastic member. During the rotation of the cam around the rotation shaft 400, the concave wheel cannot rotate around the rotation shaft 400, and the arc-shaped protrusion of the cam and the arc-shaped groove surface of the concave wheel are in sliding fit. When the cover body 300 is in a closed state, the arc-shaped protrusions of the cam and the arc-shaped grooves of the concave wheels are staggered and not completely clamped, and the elastic piece is in a compression energy storage state. When lid 300 free state, the elastic component extends release energy, and concave wheel drive cam rotates certain angle round pivot 400, until the protruding and arc groove looks joint of arc type to drive lid 300 upset. Of course, there are other ways of assembling the shaft 400, the concave wheel, the cam and the elastic member.

The second energy storage driving assembly is a torsion spring, the torsion spring is sleeved on the rotating shaft 400, and two torsion arms of the torsion spring are respectively connected to the housing 200 and the cover 300. In the closed state of the cover 300, the torsion spring is deformed to store energy. When the cover 300 is in a free state, the torsion spring deforms to release energy, and the cover 300 can be driven to turn over.

The equipment shell comprises a shell body and a cover body, wherein the cover body is pivoted on the shell body through a rotating shaft, and one of the energy storage driving assemblies is arranged between the shell body and the cover body, so that the cover body is automatically turned over. The cover body is provided with a buckle, the shell body is provided with a movable buckle tongue, and the buckle tongue is connected with the key. When the cover body is closed on the shell body, the buckling tongue is buckled on the buckle to keep the cover body on the shell body. When the key is pressed down, the buckle tongue separates from the buckle, and the cover body is automatically turned over by a certain angle under the action of the energy storage driving assembly. In the equipment shell of the comparative example, in the process from the closing of the cover body to the complete opening of the cover body, the included angle of the free end of the cover body relative to the shell body is gradually increased from 0 degree to the maximum opening angle, and the energy storage driving assembly is required to provide larger torsion force for the cover body to drive the cover body to be opened. When the cover body is completely closed, the torsion provided by the energy storage driving assembly is the largest, and the torsion acts on the buckling tongue and the key through the buckle of the cover body, so that the key can bear overlarge buckling force when the cover body is completely closed, and the condition of inclined abrasion of the key is easily caused.

The device housing of the embodiment of the application adopts the magnetic-type opening and closing key 100 to replace a buckle and a buckle tongue, and the energy storage driving assembly is arranged between the shell 200 and the cover 300. Referring to fig. 1, when the cover 300 is closed on the housing 200, the first magnet 110 and the second magnet 120 are magnetically attracted to each other, and the cover 300 remains closed on the housing 200. Referring to fig. 5, the trigger 150 can trigger the first magnet 110 to generate a magnetic pole magnetically repelling the second magnet 120 when the cover 300 is in a fully closed state, such that the cover 300 moves upward with respect to the housing 200 by a certain distance, i.e., the included angle between the free end of the cover 300 and the housing 200 gradually increases from 0 ° to a predetermined included angle (e.g., 5 ° to 10 °) driven by the magnetic repulsion force between the first magnet 110 and the second magnet 120, and then the energy storage driving assembly drives the cover 300 to continuously open to a maximum opening angle (i.e., the cover 300' indicated by the two-dot chain line in fig. 5 or fig. 8). The device case of the embodiment of the present application may be configured to provide a smaller torsion force, which is balanced by the magnetic attraction force between the first magnet 110 and the second magnet 120, by the stored energy driving assembly when the cover 300 is completely closed, compared to the device case of the comparative example. The pressing piece 130 in the embodiment of the application does not need to bear excessive buckling force, and the reliability is good.

The electronic device provided by the embodiment of the application comprises the device shell.

Among other things, the electronic device may be a smart watch that can accommodate a True Wireless Stereo (TWS) headset, a headset charging box, various wearable devices, or other electronic devices having a cover 300 and a housing 200.

The electronic equipment that this application embodiment provided, owing to adopt above-mentioned equipment shell, casing 200 need not to set up and dodge the hole, effectively reduces the dust foreign matter and gets into to dodge the hole and cause to press the possibility of feeling poor or even the dead buckle tongue of card, has promoted the reliability. The buckle and the buckle tongue are eliminated, the structure exposed out of the shell 200 is reduced, the product appearance is better, and the sound generated when the cover body 300 is closed is effectively reduced.
