Description

Shell fragment, electronic equipment's casing and electronic equipment

Technical Field

The utility model relates to the technical field of elastic sheets applied to electronic equipment, in particular to an elastic sheet, a shell of the electronic equipment and the electronic equipment.

Background

For the security problem of the electronic device, an intruder may open the housing of the electronic device and tamper with the inside of the electronic device. The tamper-proof switch is arranged in the electronic equipment and can be used for monitoring the disassembly and assembly actions of the electronic equipment, so that whether the disassembly and assembly actions exist in the shell of the electronic equipment or not can be found in time. The shell of the electronic equipment presses the tamper switch to keep the tamper switch on, and once the shell is opened, the pressure acting on the tamper switch disappears, the tamper switch is disconnected, and the abnormality of the electric signal is recorded, so that the shell of the electronic equipment is found to be disassembled.

Some existing tamper-proof switches are provided with conductive materials on corresponding structural members of electronic equipment, and the disconnection and the connection of corresponding detection signals are realized through the cooperation of the conductive materials and conductive elastic pieces on a circuit board. However, the tamper-proof switch has a large number of conductive spring plates, a relatively complex structure and easy deformation of the spring plates to influence the use; and the disconnection and the connection of signals are required to depend on conductive materials arranged on structural parts of electronic equipment, so that the cost is high. The tamper-proof switch is contacted and separated with a separation structure on the shell of the electronic equipment through a conductive elastic sheet on the circuit board, so that the connection and disconnection of the detection signal are realized. Similarly, the tamper-proof switch has a large number of conductive spring pieces and high cost; in addition, because the two elastic sheets are in an interference state and are high in stress, the elastic sheets cannot be fixed by the surface mount technology (SMT: surface Mounted Technology) through the plate-beating soldering tin, screws are required to be added, the elastic sheets and the circuit board are required to be fixed in a mode of opening screw holes, and the screw holes cannot be locked due to the shielding of tongue parts of the elastic sheets, but only the screw holes are formed in the side edges of the elastic sheets, but the fixing effect of the elastic sheets is poor, and the problem of tilting and poor contact exists on one side of the elastic sheets. The tamper-proof switch further realizes the connection and disconnection of the detection signal by compressing the sensing spring plate of the detection element in the shell of the electronic device, but the detection element has higher cost than the common spring plate structure.

Well-known and/or repeated functions and constructions are not described in detail to avoid obscuring the utility model in unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not intended to be limiting, but merely as a basis for the "summary of the utility model" and as a representative basis for teaching one skilled in the art to variously employ the present utility model in virtually any appropriately detailed structure.

The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the utility model.

In order to solve the problems in the background art, the utility model discloses a spring plate 1, wherein the spring plate 1 is matched with an electronic device 2 for use, and the spring plate 1 can be matched with the electronic device 2 and a shell of electronic equipment for use to form a tamper-proof switch of the electronic equipment so as to realize the tamper-proof function of the electronic equipment.

Referring to fig. 1 and 2, the spring plate 1 includes:

the elastic piece body comprises an elastic arm and an electric connection part.

The spring plate body can be only provided with one spring plate, and a plurality of spring plates 1 are not required to be arranged, so that the cost of the tamper-proof switch is reduced. In addition, the elastic sheet body can be made of a one-piece conductive material with good elastic deformation capability, and is simple in structure. For example, the spring plate 1 may be made of stainless steel 304. The electrical connection portion is located at a side close to the electronic device 2, and the spring arm extends from the side close to the electronic device 2 to the side far away from the electronic device 2 to achieve a certain deformation space 15 when a force close to the electronic device 2 is applied to the spring arm from the side far away from the electronic device 2.

In fig. 3, the electrical connection portion includes a first electrical connection portion 11 and two second electrical connection portions 12 for connecting with the electronic device 2. The two electrical connection portions are electrically connected to the electronic device 2, for example, the two electrical connection portions may be fixed to and electrically connected to the electronic device 2 through SMT. The first electrical connection portion 11 may be located between the two second electrical connection portions 12, and the corresponding spring arm is also located between the two second electrical connection portions 12; the two second electrical connection portions 12 may be formed as flat plates, and the two second electrical connection portions 12 extend from a side connected with the spring arm to a side far away from the spring arm to form flat plates, so that the flat plates are fixed and electrically connected with the electronic device 2 through SMT. Because the second electrical connection part 12 and the spring arm do not have the problems that two spring plates in the existing structure interfere, the stress is large, and the spring plate is fixed only by the way that screws and threaded holes are matched for locking due to the fact that the tongue part of the spring plate shields the electrical connection part, the second electrical connection part 12 of the spring plate 1 can be completely fixed with the electronic device 2 through SMT and the electrical connection of the second electrical connection part 12 and the electronic device 2 is realized, and in terms of the structure realization process of the tamper-proof switch, the fixing structures such as threaded holes and the like are not required to be processed on the spring plate 1 and the electronic device 2, the process is simpler, and the cost is lower.

The spring arms comprise a first spring arm 13 and a second spring arm 14. One end of the first spring arm 13 is connected with the first electrical connection part 11, and the other end of the first spring arm 13 is connected with one of the second electrical connection parts 12; one end of the second elastic arm 14 is connected with the first electrical connection portion 11, and the other end of the second elastic arm 14 is connected with the other second electrical connection portion 12.

The first elastic arm 13 and the second elastic arm 14 may be disposed in mirror symmetry with respect to the first electrical connection portion 11, and when the first elastic arm 13 and the second elastic arm 14 are subjected to a force in a set direction, the first elastic arm 13 and the second elastic arm 14 deform, and the first electrical connection portion 11 abuts against the electronic device 2 and is electrically connected with the electronic device 2. The setting direction is a direction toward the first electrical connection portion 11. Referring to fig. 4 and 5, in a natural state, the elastic sheet 1 has no contact relationship between the first electrical connection portion 11 and the electronic device 2. The force can be applied to the first elastic arm 13 and the second elastic arm 14 at the same time, so that the first elastic arm 13 and the second elastic arm 14 deform at the same time, so that the first electrical connection portion 11 connected with the first elastic arm 13 and the second elastic arm 14 moves towards the direction close to the electronic device 2, and the first electrical connection portion 11 abuts against the electronic device 2 and forms an electrical connection relationship with the electronic device 2 in combination with fig. 6 and fig. 7.

The electric connection or separation with the electronic device 2 is realized through the conductive elastic sheet 1, the structure is simple, no additional conductive material is needed, and the cost is low. Through the two second electric connection parts 12 and the electronic device 2, the elastic arm is deformed by applying the acting force in the set direction to the elastic arm, and meanwhile, the first electric connection part 11 connected with the elastic arm is electrically connected with the electronic device 2, so that the conduction of the detection signal is realized. The spring arm can be electrically connected with the electronic device 2 without additional fixing structures such as screws, so that the structural design process of the tamper-proof switch is simpler and the cost is lower.

In some embodiments, referring again to fig. 2, the first spring arm 13 includes a first angled portion 131, a first bent portion 132, a second bent portion 133, and a second angled portion 134.

One end of the first inclined portion 131 is connected to one end of one of the second electrical connection portions 12, and the other end of the first inclined portion 131 extends toward one end of the first bending portion 132 along the first direction and is connected to one end of the first bending portion 132. That is, after the other end of the first inclined portion 131 extends toward the first bending portion, the first spring arm 13 and the second electrical connection portion 12 do not mutually block, so that the second electrical connection portion 12 can be electrically connected with the electronic device 2 through SMT.

The other end of the first bending portion 132 is connected to one end of the second bending portion 133, and the other end of the second bending portion 133 is connected to one end of the second inclined portion 134. The other end of the second inclined portion 134 extends along the second direction and is connected to the first electrical connection portion 11. The first bending part 132 forms a convex first bending 135 in the direction capable of protruding toward the second spring arm 14; the second bending portion 133 forms a convex second bending 136 toward the direction concave to the second spring arm 14. The first bending portion 132 and the second bending portion 133 are each formed with a deformation space 15 in which the first spring arm 13 is deformed in a set direction.

Specifically, the first spring arm 13 may be formed by bending a plate with conductive properties, where the first bending portion and the second bending portion respectively protrude towards two different directions to form corresponding bends, so that the first bending portion 132 and the second bending portion 133 are both formed with a deformation space 15 for deforming the first spring arm 13 along a set direction. Referring to fig. 2 again, the first bending portion 132 and the second bending portion 133 are disposed along the set direction, and the second bending portion 133 is closer to the electronic device 2 than the first bending portion 132.

The deformation spaces 15 formed by the first bending portion 132 and the second bending portion 133 for deforming the first spring arm 13 in the set direction may be the same or different in size. The first bending portion 132 and the second bending portion 133 make the elastic sheet 1 have higher elasticity, and reduce impact on the electronic device 2 under the condition that the elastic sheet 1 receives a larger acting force, thereby increasing stability of the detection signal.

The first bending portion 132 may be formed with a biasing portion for applying a biasing force in a set direction, and the biasing portion may be formed as a flat plate; or the side of the first bending portion 132 away from the electronic device 2 is formed into a flat plate structure before forming the first bending, and the flat plate structure is used as a force application portion, so that the force in the set direction is better applied to the first elastic arm 13, and the first electrical connection portion 11 is quickly and stably moved towards the electronic device 2 after the first elastic arm 13 is deformed, so that a stable electrical connection relationship is formed with the electronic device 2.

The second inclined portion 134 is designed such that a certain gap is formed between the second bending portion 133 and the electronic device 2 when the first arm 13 is not subjected to the force in the set direction, and the second bending portion 133 still does not interfere with the electronic device 2 after the first arm 13 is deformed when the first arm 13 is subjected to the force in the set direction.

In some embodiments, similar to the first spring arm 13, the second spring arm 14 includes a third angled portion 141, a third bent portion 142, a fourth bent portion 143, and a fourth angled portion 144.

One end of the third inclined portion 141 is connected to one end of the other second electrical connection portion 12, and the other end of the third inclined portion 141 extends toward one end of the third bending portion 142 along the third direction and is connected to one end of the third bending portion 142. The other end of the third bending portion 142 is connected to one end of the fourth bending portion 143, and the other end of the fourth bending portion 143 is connected to one end of the fourth inclined portion 144. The other end of the fourth inclined portion 144 extends in the fourth direction and is connected to the first electrical connection portion 11. The third bending part 142 forms a convex third bending 145 towards the direction of the first spring arm 13, and the fourth bending part 143 forms a convex fourth bending 146 towards the direction of the first spring arm 13; the third bending portion 142 and the fourth bending portion 143 are each formed with a deformation space 15 in which the second spring arm 14 deforms in the set direction.

Referring to fig. 2 again, the second spring arm 14 and the first spring arm 13 may be symmetrically disposed about the first electrical connection portion 11, and the first spring arm 13 and the second spring arm 14 are simultaneously subjected to a force along a set direction. The design and effect of the parts of the second spring arm 14 are similar to those of the first spring arm 13, and will not be described again.

In addition, the first spring arm 13 and the second spring arm 14 have no contact interference relationship, that is, the first bending 135 and the third bending 145 have no contact regardless of whether the spring 1 is subjected to the force in the set direction or the force in the set direction. The structure is different from the existing structure in that two elastic pieces are matched with a separation structure on a shell of the electronic equipment, and the risk that the elastic pieces are warped due to the fact that acting force is applied to the elastic pieces when the separation structure is inserted between the two elastic pieces in two contacts to separate the two elastic pieces does not exist.

In some embodiments, the elastic sheet 1 is integrally formed, that is, the elastic sheet 1 can be formed by bending a plate with a certain length and width and conductive performance according to the structure, and compared with the existing elastic sheet, the manufacturing process is simpler and the cost is lower.

In some embodiments, the second electrical connection portion 12 is provided with a through hole 121 for attaching and fixing the electronic device 2, and the through hole 121 penetrates through the second electrical connection portion 12. Referring to fig. 3 again, two through holes 121 may be respectively disposed on the two second electrical connection portions 12, and the through holes 121 may increase the tin consumption of the elastic sheet 1 when electrically connected to the electronic device 2 through SMT, so as to increase the connection firmness between the elastic sheet 1 and the electronic device 2.

The utility model also discloses a housing of the electronic device, as shown in fig. 8, comprising a detachable first structure 3 and a detachable second structure 4. Wherein a spring plate 1 according to any of the above embodiments is arranged between the first structure 3 and the second structure 4.

The first structural body 3 and the second structural body 4 provide a force in a set direction in a state where the first structural body 3 and the second structural body 4 are assembled with each other to conduct a circuit provided on the electronic device 2, and the first structural body 3 and the second structural body 4 release a force in a set direction in a state where the first structural body 3 and the second structural body 4 are separated from each other to break a circuit provided on the electronic device 2. When the circuit is on, a corresponding detection signal is generated, and when the circuit is off, a corresponding detection signal is not generated.

The electronic device 2 may be a PCB detection circuit board, and three metal areas 21 connected to the chip are reserved on the PCB detection circuit board, wherein two metal areas 21 respectively form an electrical connection relationship with the second electrical connection portion 12, and the remaining metal area 21 may be used to form an electrical connection relationship with the first electrical connection portion 11.

When the elastic sheet 1 is not acted by the acting force in the set direction, the first electrical connection part 11 and the metal area 21 are in a disconnected state, when the elastic sheet 1 is acted by the acting force in the set direction, the elastic sheet 1 is deformed to enable the first electrical connection part 11 to be in contact with the metal area 21, a circuit is conducted, a corresponding detection system can detect a conducting signal, and further whether the shell of the electronic equipment is detached or not is judged.

In some embodiments, the dome 1 has opposite first and second sides in the direction of the force.

The first side of the elastic sheet 1 is connected with the first structural body 3, specifically, the electronic device 2 is arranged on the first structural body 3, and the elastic sheet 1 is connected with the electrical device; the second structure 4 is provided with a pressing member 41 for pressing the spring arm to provide a force in a set direction on a side facing the internal space of the electronic device. The press-fitting member 41 may be two press-fitting plates or one press-fitting column protruding from the surface of the second structural body 4 toward the inner surface of the electronic device.

Taking an electronic device as a notebook computer as an example, the second structure body 4 may be a D-case of the notebook computer.
