Description

Technical Field

[0001] This application relates to the field of mechanical fixation technologies, and particularly to a pressing structure and an electronic device. Background Art

[0002] In the field of mechanical fixation technologies, pressing and fixing is a common fixing method. In a pressing and fixing structure, one end of a spring piece is usually pressed on a target structural member, and the other end is fixed with a screw. During the process of tightening the screw, one end of the spring piece presses the target structural member against the target wall surface. During the process of tightening the screw, the spring piece is very likely to damage the target structural member. Summary of the Utility Model

[0003] To solve the above problems, an embodiment of this application provides a pressing structure that uses the elastic potential energy of the pressing structure to press a target structural member against a target wall surface, solving the problem that the target structural member is very likely to be damaged when pressing the target structural member.

[0004] For this reason, the following technical solutions are adopted in the embodiments of this application:

[0005] In a first aspect, an embodiment of this application provides a pressing structure for pressing a target structural member against a target wall surface, that is, the outer wall surface of the target structural member is in close contact with the target wall surface. Among them, a support wall surface is provided at a relative position of the target wall surface, and there is a gap between the support wall surface and the target structural member. The pressing structure of the embodiment of this application includes: a pressing main body. The pressing main body includes an elastic structure extending along a preset direction. The elastic structure has a first abutting portion and a second abutting portion that are oppositely arranged in a first direction, and the first direction is perpendicular to the preset direction. Among them, when the elastic structure generates a tensile deformation along the preset direction, the first abutting portion and the second abutting portion approach each other, and the pressing main body can be arranged in the gap. When the pressing main body with a tensile deformation is arranged in the gap, under the action of the elastic potential energy generated by the tensile deformation, the first abutting portion abuts against the target structural member and exerts a first acting force on the target structural member, and the target structural member is in close contact with the target wall surface. At the same time, the second abutting portion abuts against the support wall surface, and the second abutting portion exerts a second acting force on the support wall surface, and the second acting force is opposite to the first acting force in direction.

[0006] It should be further noted that the embodiment of the present application provides a pressing structure, which includes a pressing main body. The pressing main body includes an elastic structure extending along a preset direction. In a first direction perpendicular to the preset direction, the elastic structure is provided with opposite first abutting portions and second abutting portions. Under the action of an external force, the elastic structure can undergo elastic deformation. Further, the first abutting portion and the second abutting portion on the elastic structure approach each other along the first direction. When the external force is withdrawn or becomes smaller, under the action of elastic potential energy, the first abutting portion and the second abutting portion on the elastic structure move away from each other, and the press main body has a tendency to return to the shape before elastic deformation. Therefore, when the pressing structure after elastic deformation is placed in the gap formed by the target structural member and the supporting wall surface, the first abutting portion can abut against the target structural member, and the second abutting portion abuts against the supporting wall surface. Under the action of elastic potential energy, the pressing structure presses the target structural member against the target wall surface.

[0007] Further, the existing pressing structure of the elastic sheet and the screw fastening is similar to a rigid pressing structure, while the pressing structure of the embodiment of the present application is similar to an elastic pressing structure. That is to say, within the range of elastic potential energy, the pressing structure of the embodiment of the present application can elastically press the target structural member against the target wall surface. Therefore, the force applied by the pressing structure of the embodiment of the present application to the target structural member can be controlled within the force-bearing range of the target structural member without damaging the target structural member itself.

[0008] In addition, the pressing structure of the embodiment of the present application also allows a certain displacement or deformation of the target structural member. Exemplarily, when pressing a power tube against the target heat dissipation surface of a radiator, the power tube can undergo a certain displacement due to the deformation of the radiator, or the power tube itself can deform due to heat. The target structural member can exert a reaction force on the pressing structure of the embodiment of the present application, thereby changing the first force applied by the first abutting portion to the target structural member.

[0009] In addition, for the pressing structure of the embodiment of the present application, it only needs to place the pressing structure in the gap formed by the target structural member and the supporting wall surface after the pressing main body undergoes elastic deformation. The entire installation process is fast and convenient. During the assembly process of the pressing structure of the embodiment of the present application, the operation steps of personnel are reduced, the processing cycle of the entire product including the target structural member is shortened, the installation is fast and efficient, and it can be applied to the usage scenario of batch delivery. Exemplarily, in an electronic device, it may be necessary to press a large number of power tubes. The pressing structure of the embodiment of the present application can reduce the operation steps of personnel during the assembly process of the power tubes, shorten the assembly cycle of the entire electronic device, and can achieve the task of rapid batch delivery of the electronic device.

[0010] In a possible implementation manner, the first abutting portion and / or the second abutting portion are arranged in a plurality along a second direction, and the second direction is perpendicular to the preset direction and the first direction.

[0011] In this implementation, by arranging the first abutting portion and / or the second abutting portion in a plurality along the second direction, the positions where the pressing structure of the embodiment of the present application applies force to the target structural member can be increased, the force-bearing area of the pressing structure is increased, thereby reducing the pressure of the pressing structure on the target structural member and reducing the possibility of crushing the target structural member. Additionally, arranging a plurality of abutting portions along the second direction can reduce the requirement for the surface flatness of the target structural member, and the pressing structure can adapt to the surface deformation of the target structural member. That is to say, when the target structural member itself deforms and causes a change in the contact surface of the pressing structure, or there is a large difference in flatness on the surface of the target structural member in contact with the pressing structure, arranging a plurality of abutting portions along the second direction can be well adapted to this situation.

[0012] In another possible implementation, the first abutting portion and / or the second abutting portion are arranged in a plurality along a preset direction.

[0013] In this implementation, arranging the first abutting portion and / or the second abutting portion in a plurality along the preset direction can increase the positions where the pressing structure of the embodiment of the present application applies force to the target structural member, increase the force-bearing area of the pressing structure, thereby reducing the pressure of the pressing structure on the target structural member and reducing the possibility of crushing the target structural member. Additionally, it can be applicable to the application scenarios of multiple target structural members. Exemplarily, in an electronic device, a plurality of power tubes may be provided. When the pressing structure is provided with a plurality of abutting portions along the preset direction, the pressing structure can press a plurality of power tubes at one time, improving the working efficiency.

[0014] In another possible implementation, a plurality of target structural members are arranged along the target wall surface; under the action of the elastic potential energy generated by the tensile deformation, the first abutting portion abuts against the plurality of target structural members and applies a first force to the plurality of target structural members, and the plurality of target structural members are closely attached to the target wall surface.

[0015] In this implementation, when a plurality of target structural members need to be pressed against the target wall surface, the pressing structure of the embodiment of the present application can press a plurality of target structural members simultaneously. Exemplarily, in an electronic device, a plurality of power tubes may be provided. The pressing structure of the embodiment of the present application can press a plurality of power tubes at one time, improving the working efficiency.

[0016] In another possible implementation, at least two target structural members are arranged oppositely. The target structural member includes a first wall surface and a second wall surface arranged oppositely. The first wall surface is closely attached to the target wall surface, and there is a gap between the second wall surface and the support wall surface; wherein, the second wall surface of one target structural member is the support wall surface of the other target structural member.

[0017] In this implementation manner, the pressing structure of the embodiments of the present application can be applied to the scenario where target structural members are arranged on both sides of a gap. When multiple target structural members are arranged on both sides of the gap, the side of each target structural member away from the target wall surface is the supporting wall surface of the other target structural member on the opposite side. When it is necessary to press the target structural members on both sides against the target wall surfaces on both sides, the pressing structure of the embodiments of the present application can press multiple target structural members on both sides simultaneously. Exemplarily, in an electronic device, multiple power tubes can be arranged on both sides of a certain radiator (such as an S-shaped heat dissipation channel), and the pressing structure of the embodiments of the present application can press multiple power tubes on both sides at one time, improving the working efficiency.

[0018] In another possible implementation manner, the elastic structure extends along a preset trajectory to form a first abutting portion and / or a second abutting portion; the preset trajectory includes a preset curve or a preset broken line.

[0019] In this implementation manner, an exemplary way to form a first abutting portion and / or a second abutting portion through a preset trajectory is provided, and the preset trajectory includes but is not limited to a preset curve or a preset broken line.

[0020] In another possible implementation manner, the elastic structure includes a first elastic sheet and a second elastic sheet. The first elastic sheet protrudes and bends in a first direction to form a first abutting portion, and the second elastic sheet protrudes and bends in the opposite direction of the first direction to form a second abutting portion.

[0021] In this implementation manner, an exemplary implementation manner of the first abutting portion and / or the second abutting portion is provided. Exemplarily, the first abutting portion and / or the second abutting portion can be formed by bending the first elastic sheet and the second elastic sheet.

[0022] In another possible implementation manner, the first elastic sheet also protrudes and bends in the opposite direction of the first direction to form a second abutting portion; the second elastic sheet protrudes and bends in the first direction to form a first abutting portion.

[0023] In this implementation manner, one elastic sheet can be bent in sequence to form a first abutting portion, a second abutting portion, a first abutting portion, etc., and the other elastic sheet can be bent in sequence to form opposite second abutting portions, opposite first abutting portions, opposite second abutting portions, etc. This implementation manner improves the overall stiffness of the pressing structure of the present application.

[0024] In another possible implementation manner, the distance between the first abutting portion and the second abutting portion is related to the gap; wherein, when the elastic structure is in a natural state, the distance between the first abutting portion and the second abutting portion is greater than the gap; when the elastic structure is in a tensile deformation state, the distance between the first abutting portion and the second abutting portion is less than the gap.

[0025] In this implementation, the distance between the first abutting portion and the second abutting portion is related to the gap. According to different application scenarios, the gap between the target structural member and the supporting wall surface may be different. Therefore, by setting the distance between the first abutting portion and the second abutting portion, the pressing structure of the embodiment of the present application can be applicable to different application scenarios.

[0026] In another possible implementation, the length of the elastic structure extending along the preset direction is related to the number of target structural members.

[0027] In this implementation, in practical applications, there may be scenarios where multiple target structural members need to be pressed. Therefore, by setting the length of the elastic structure extending along the preset direction, the pressing structure of the embodiment of the present application can press multiple target structural members, with simple operation and high installation efficiency.

[0028] In another possible implementation, the pressing structure is integrally formed.

[0029] In this implementation, the pressing structure of the embodiment of the present application is integrally formed, which improves the processing efficiency of the pressing structure.

[0030] In another possible implementation, the target structural member is a power tube, and the target wall surface is the heat dissipation surface of the heat dissipation device.

[0031] In this implementation, in an application scenario, the target structural member can be a power tube, and the target wall surface is the heat dissipation surface of the heat dissipation device. The pressing structure of the embodiment of the present application can press the power tube against the heat dissipation surface of the heat dissipation device, thereby achieving the heat dissipation purpose of the power tube.

[0032] In a second aspect, the embodiment of the present application provides an electronic device, including a target structural member and any one of the pressing structures described above, and the pressing structure is used to press the target structural member against the target wall surface.

[0041] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0042] The term "and / or" in this article is a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The symbol " / " in this article represents that the associated objects are in an "or" relationship, for example, A / B represents A or B.

[0043] The terms "first" and "second" etc. in the description and claims of this article are used to distinguish different objects, rather than to describe the specific order of the objects. For example, the first response message and the second response message etc. are used to distinguish different response messages, rather than to describe the specific order of the response messages.

[0044] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific manner.

[0045] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" refers to two or more. For example, a plurality of processing units refers to two or more processing units, etc.; a plurality of elements refers to two or more elements, etc.

[0046] In the field of mechanical fixing technology, different fixing methods are usually adopted according to different usage scenarios. For example, after the target structural member is installed, if there is a gap between the target structural member and the target wall surface, the usage effect of the target structural member will be affected. Therefore, a pressing device or a pressing structure for pressing the target structural member against the target wall surface is required to make the target structural member closely fit the target wall surface, so as to ensure the normal use of the target structural member.

[0047] In one solution, the target structural member is pressed by using a spring piece, so that the target structural member closely fits the target wall surface to ensure the usage effect of the target structural member. As Figure 1 shown, one end of the spring piece 3 is fastened to the component 4 by screws, and the other end presses the first wall surface on the upper side of the target structural member. The first wall surface on the lower side of the target structural member 2 is pressed against the target wall surface 401 of the component 4, realizing the close fit between the target structural member 2 and the target wall surface 401. Exemplarily, the target structural member 2 can be a power tube, and the target wall surface 401 can be the heat dissipation surface of a heat dissipation device. In order to ensure the close contact between the power tube and the heat dissipation surface, the spring piece pressing method as Figure 1 shown is adopted. The spring piece is placed above the power tube, and then the spring piece is locked by screws. The power tube is pressed against the heat dissipation surface by relying on the elasticity of the spring piece.

[0048] In this solution, each target structural member needs to use an independent or a group of spring pieces, and screws need to be used to press the spring pieces on the power tube one by one to ensure the close fit between the power tube and the heat dissipation surface. When the number of power tubes is large, the manufacturing process of this solution is complex and the cost is high. In addition, each target structural member is pressed by relying on the arc convex points of the spring piece, and the contact position is generally point contact or line contact, which is easy to cause warping or displacement. Taking the target structural member 2 as a power tube as an example, when the pressure is too large, the power tube will be crushed, causing a combustion risk.

[0049] To solve the problems in the above solution, an embodiment of the present application provides a pressing structure, which uses the elastic potential energy of the pressing structure to press the target structural member against the target wall surface, solving the problem that the target structural member is easily damaged when being pressed.

[0050] Next, the embodiments of the present application will be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Those of ordinary skill in the art can know that with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0051] Please refer to Figure 2a 、 Figure 2b 、 Figure 2c 、 Figure 2d , Figures 2a - 2dThe figure shows a schematic diagram of a pressing structure. As Figure 2a shown, the pressing structure 100 of the embodiment of the present application includes a pressing main body, and the pressing main body includes an elastic structure extending along a preset direction, and the first abutting portion 101 and the second abutting portion 102 which are oppositely arranged on the elastic structure.

[0052] Optionally, the pressing structure 100 includes a first end portion 103 and a second end portion 104. Optionally, the pressing structure 100 can also be provided with connecting devices such as handles, hooks, ropes, steel wires, etc. on the first end portion 103 and the second end portion 104, so as to facilitate the user or the device to apply forces on the first end portion 103 and the second end portion 104.

[0053] Exemplarily, taking the target structural member 2 as a power tube for illustration, after the power tube is inserted, it can be that the first end portion 103 is fixed and the second end portion 104 applies a pulling force away from the first end portion 103; or the first end portion 103 and the second end portion 104 respectively apply pulling forces away from each other. Under the action of an external pulling force, the distance dimension L between the first abutting portion 101 and the second abutting portion 102 of the pressing structure 100 becomes smaller, and the pressing structure 100 is placed between two rows of power tubes in a metal cavity or near a water channel. As the external pulling force is removed, the metal elastic sheet rebounds, and the distance dimension has a tendency to return to the original distance dimension L, so that the power tubes on both sides are all pressed at one time.

[0054] Optionally, as Figure 2a shown, the elastic structure includes a first elastic sheet and a second elastic sheet. The first elastic sheet protrudes and bends in the first direction to form the first abutting portion 101, and the second elastic sheet protrudes and bends in the opposite direction of the first direction to form the second abutting portion 102. Exemplarily, as Figure 2a shown, the first elastic sheet can be the first elastic sheet, the third elastic sheet, the fifth elastic sheet, the seventh elastic sheet arranged from bottom to top in the second direction; the second elastic sheet can be the second elastic sheet, the fourth elastic sheet, the sixth elastic sheet, the eighth elastic sheet arranged from bottom to top in the second direction.

[0055] Optionally, the first elastic sheet also protrudes and bends in the opposite direction of the first direction to form the second abutting portion 101; the second elastic sheet protrudes and bends in the first direction to form the first abutting portion 102. As Figure 2a shown, taking the first elastic sheet arranged from bottom to top in the second direction as an example, the first elastic sheet can be bent in sequence to form the first abutting portion 101, the second abutting portion 102, the first abutting portion 101, etc. As Figure 2aAs shown, taking the second elastic piece arranged from bottom to top in the second direction as an example, the second elastic piece can be bent successively to form opposite second abutting parts 102, opposite first abutting parts 101, opposite second abutting parts 102, etc. Compared with the first elastic piece that only bends to form the first abutting part 101 and the second elastic piece that only bends to form the second abutting part 102, this implementation method improves the overall stiffness of the pressing structure of the present application.

[0056] Exemplarily, the pressing structure 100 can adopt a bidirectional grid metal elastic piece structure, which can simply and quickly apply a stable and uniform pressing force to all power tubes distributed on both sides of the pressing structure 100. The first elastic piece and the second elastic piece are set as two mirrors symmetric about a preset direction. One elastic piece is provided with a first abutting part 101, and the other elastic piece is provided with a second abutting part 102 that is a mirror image of the first abutting part 101.

[0057] Optionally, the pressing structure 100 is integrally formed. Compared with other processing methods, using integral forming can improve the processing efficiency of the pressing structure 100. Exemplarily, the pressing structure in the embodiment of the present application adopts an integrated structure design and is formed by a simple mold in one processing, thus avoiding independently processing each elastic piece and improving the manufacturing efficiency of the pressing structure 100.

[0058] As Figure 2b shown, optionally, the distance between the first abutting part 101 and the second abutting part 102 is related to the gap between the target structural member 2 and the target wall surface 401. That is to say, when the pressing structure 100 is in the initial state, the distance between the first abutting part and the second abutting part is greater than the gap; when the pressing structure 100 is in the tensile deformation state, the distance between the first abutting part 101 and the second abutting part 102 is less than the gap. Depending on different application scenarios, the gap between the target structural member 2 and the supporting wall surface 401 may be different. Therefore, by setting the distance between the first abutting part 101 and the second abutting part 102, the pressing structure 100 in the embodiment of the present application can be applicable to different application scenarios.

[0059] As Figure 2bAs shown, exemplary, when the pressing structure 100 does not undergo elastic deformation, the distance between the first abutting portion 101 and the second abutting portion 102 is L. When the pressing structure 100 undergoes elastic deformation, the distance between the first abutting portion 101 and the second abutting portion 102 becomes L1. Wherein, L1 is less than L. The distance between the target structural member 2 and the supporting wall surface is L2. Wherein, L1 < L2 < L. Therefore, after the pressing structure 100 undergoes elastic deformation, it can enter the gap formed by the target structural member 2 and the supporting wall surface. After the pressing structure 100 is placed in the gap formed by the target structural member 2 and the supporting wall surface, the distance between the first abutting portion 101 and the second abutting portion 102 is L1. Under the action of the potential energy of the elastic deformation, the distance between the first abutting portion 101 and the second abutting portion 102 becomes L2. And there is still a gap between the distance L2 and L, that is to say, there is still some elastic potential energy in the pressing structure 100. Under the action of the elastic potential energy of the remaining partial elastic deformation, the first abutting portion 101 abuts against the target structural member 2 and applies a first acting force to the target structural member 2, and the second abutting portion 102 applies a second acting force in the opposite direction to the supporting wall surface. Under the action of the first acting force, the target structural member 2 is pressed against the target wall surface 401.

[0060] Optionally, the first abutting portion 101 and / or the second abutting portion 102 are arranged in a plurality along a preset direction. Arranging the first abutting portion and / or the second abutting portion in a plurality along a preset direction can increase the position where the pressing structure in the embodiment of the present application applies an acting force to the target structural member, increase the force-bearing area of the pressing structure, thereby reducing the pressure of the pressing structure on the target structural member and reducing the possibility of crushing the target structural member.

[0061] Furthermore, arranging the first abutting portion 101 and / or the second abutting portion 102 in a plurality along a preset direction can be applicable to application scenarios of multiple target structural members. Exemplary, in an electronic device, a plurality of power tubes may be provided. When the pressing structure is provided with a plurality of abutting portions along a preset direction, the pressing structure can press a plurality of power tubes at one time, improving the working efficiency.

[0062] As Figure 2c shown, when opposite acting forces are applied to the first end portion 103 and the second end portion 104, the pressing structure 100 may undergo elastic deformation, and then the first abutting portion 101 and the second abutting portion 102 approach each other and can enter the gap formed by the target structural member 2 and the supporting wall surface. When the acting forces applied to the first end portion 103 and the second end portion 104 are withdrawn or reduced, due to the action of the elastic potential energy of the elastic deformation, the first abutting portion 101 and the second abutting portion 102 move away from each other, the first abutting portion 101 abuts against the target structural member 2, applies a first acting force to the target structural member 2, and the second abutting portion 102 applies a second acting force in the opposite direction to the supporting wall surface. Under the action of the first acting force, the target structural member 2 is pressed against the target wall surface 401.

[0063] As shown Figure 2d Optionally, the first abutting portion 101 and / or the second abutting portion 102 are arranged in a plurality along the second direction, and the second direction is perpendicular to the preset direction and the first direction.

[0064] Furthermore, by arranging the first abutting portion 101 and / or the second abutting portion 102 in a plurality along the second direction, the positions where the pressing structure in the embodiment of the present application applies force to the target structural member 2 can be increased, the force-bearing area of the pressing structure is increased, thereby reducing the pressure of the pressing structure 2 on the target structural member, and reducing the possibility of crushing the target structural member 2.

[0065] Optionally, arranging a plurality of abutting portions along the second direction can reduce the requirement for the surface flatness of the target structural member 2, and the pressing structure 100 can adapt to the surface deformation of the target structural member 2. That is to say, when the target structural member 2 itself deforms and causes a change in the contact surface of the pressing structure 100, or there is a large flatness difference on the surface of the target structural member 2 in contact with the pressing structure 100, arranging a plurality of abutting portions along the second direction, and the plurality of abutting portions can elastically deform along the first direction, so as to be applicable to the situation where the abutting surface of the target structural member 2 is uneven.

[0066] Please refer to Figure 3 , Figure 3 which shows a schematic diagram of a scenario using a pressing structure. As Figure 3 shown, optionally, a plurality of target structural members 2 are arranged along the target wall surface. Under the action of the elastic potential energy generated by the tensile deformation, the first abutting portion 101 abuts against the plurality of target structural members 2 and applies a first force to the plurality of target structural members 2, and the plurality of target structural members 2 are closely attached to the target wall surface 401.

[0067] Furthermore, when a plurality of target structural members 2 need to be pressed against the target wall surface 401, the pressing structure 100 in the embodiment of the present application can press a plurality of target structural members 2 at the same time. Exemplarily, as Figure 3 shown, in an electronic device, a plurality of power tubes may be provided, and the pressing structure in the embodiment of the present application can press a plurality of power tubes at one time, improving the working efficiency.

[0068] Optionally, at least two target structural members 2 are arranged oppositely, the target structural member 2 includes a first wall surface 201 and a second wall surface 202 arranged oppositely, the first wall surface 201 is closely attached to the target wall surface 401, and there is a gap between the second wall surface 202 and the support wall surface. Among them, the second wall surface 202 of one target structural member 2 is the support wall surface of another target structural member 2. That is to say, the support wall surface may be the second wall surface 202 of the target structural member 2 in the relative position.

[0069] Furthermore, the pressing structure 100 in the embodiments of the present application can be applied to the scenario where the target structure members 2 are arranged on both sides of a gap. When multiple target structure members 2 are arranged on both sides of the gap, the side of each target structure member 2 away from the target wall surface 401 is the supporting wall surface for the other target structure member on the opposite side. When it is necessary to press the target structure members 2 on both sides against the target wall surfaces 401 on both sides, the pressing structure 100 in the embodiments of the present application can press multiple target structure members 2 on both sides simultaneously.

[0070] Exemplarily, as Figure 3 shown, in an electronic device, multiple power tubes can be arranged on both sides of a certain radiator (such as an S-shaped heat dissipation channel). The pressing structure in the embodiments of the present application can press multiple power tubes on both sides at one time, improving the working efficiency.

[0071] Optionally, the target structure member 2 is a power tube, and the target wall surface 401 is the heat dissipation surface of the heat dissipation device. That is to say, the target structure member can be a power tube, and the target wall surface is the heat dissipation surface of the heat dissipation device. The pressing structure in the embodiments of the present application can press the power tube against the heat dissipation surface of the heat dissipation device, thereby achieving the heat dissipation purpose of the power tube.

[0072] Optionally, as Figure 3 shown, the length of the elastic structure extending along the preset direction is related to the number of target structure members 2. That is to say, the more the number of target structure members 2 along the preset direction, the longer the length of the elastic structure extending along the preset direction, so that the pressing structure 100 in the embodiments of the present application can press multiple target structure members at one time, with simple operation and high installation efficiency.

[0073] In the embodiments of the present application, for the convenience of explaining the technical solutions of the embodiments of the present application, the heat dissipation problem of power tubes is used for exemplary illustration, but it does not limit the applicable scenarios of the pressing structure in the embodiments of the present application. For example, the target structure member can be a power tube, and the target wall surface can be the heat dissipation surface of the heat dissipation device.

[0074] The technical solutions of the embodiments of the present application can be used not only for pressing the power tube itself, but also for the rapid pressing of unilateral / bilateral target structure members in other cases where there are support structures on both sides, and are not limited to the energy field. In other embodiments, the target structure member can be a workpiece to be processed, and the target wall surface can be the installation surface of the equipment platform. After the pressing structure in the embodiments of the present application presses the workpiece to be processed against the installation surface of the equipment platform, the workpiece to be processed is processed, and the processing work can be drilling, grinding, painting, powder spraying, etc.

[0075] Taking the power tube as an example of the target structural member, the pressing structure 100 of the embodiment of the present application can meet the pressing requirements of the power tubes of high-power energy products, and is particularly applicable to the scenarios where the power tubes on both sides or one side of structures such as S-shaped water channels and multiple cavities need to be pressed. Exemplarily, in the pressing scenario of a large number of power tubes arranged in a matrix, the use effect of the pressing structure 100 is remarkable, and the power tubes arranged on one side or both sides can be pressed at one time.

[0076] Exemplarily, the target structural member can be a power tube, and the target wall surface can be the heat dissipation surface of the heat dissipation device. The pressing structure of the embodiment of the present application can press the power tube onto the heat dissipation surface of the heat dissipation device, so as to realize the heat dissipation of the target structural member and ensure the normal operation of the power tube. In the embodiment of the present application, the power tube can be one or more of various types of switching devices such as metal oxide semiconductor field effect transistor (MOSFET), bipolar junction transistor (BJT), insulated gate bipolar transistor (IGBT), gallium nitride (GaN), etc., and the embodiment of the present application will not list them one by one.

[0077] With the rapid development of the new energy industry, the photovoltaic industry and the electric vehicle industry usually need to use a large number of power tubes. For example, a large number of power tubes are often required in energy products. Products with larger power will use more than hundreds of power conversion systems (PCS for short). The use of a large number of power tubes brings huge challenges to the manufacturability and reliability of the products. The power tubes generate a large amount of heat and have extremely high requirements for heat dissipation. When dissipating heat naturally through the housing or through liquid cooling with a water cooling pipe, elastic pieces are required to press each power tube to ensure close fitting and smooth heat dissipation. Once the fitting is not tight, it will cause the power tube to quickly heat up until it catches fire and burns.

[0078] Optionally, the pressing structure 100 can be used in power modules in product devices such as electric vehicle charging stations or charging piles, industrial and commercial photovoltaic inverters, etc. That is to say, the products that can use the pressing structure 100 are mainly high-power products using power tubes, including but not limited to product devices such as electric vehicle charging stations or charging piles, industrial and commercial photovoltaic inverters, etc. Exemplarily, the pressing structure 100 is mainly used in power modules or products containing power tubes.

[0079] That is to say, the first abutting portion 101 and the second abutting portion 102 can be arranged in multiple numbers along a preset direction or a second direction. Therefore, when the pressing structure 100 abuts against the power device, the contact area is larger than that of a conventional point-contact elastic sheet. When multiple abutting portions simultaneously press the power transistor, the reliability of the pressing contact area is also ensured.

[0080] Furthermore, the pressing force of the pressing structure 100 is dispersed to multiple abutting portions, making the pressing contact mode approximate to surface contact, reducing the pressure generated by pressing, and avoiding crushing of the power transistor.

[0081] Furthermore, the pressing structure 100 can quickly press the power transistors arranged in rows on one side or both sides, avoiding the installation work of fastening screws one by one, with high working efficiency, and can quickly press the power transistors on one side or both sides.

[0082] Exemplarily, the length of the elastic structure and the number of abutting portions can be customized according to the number of power transistors; they can also be made into standardized size numbers according to usage conditions. The pressing structure 100 can achieve the technical effect of pressing all the power transistors on both sides with one operation.

[0083] Please refer to Figure 4 , Figure 4 which shows a schematic structural diagram of another pressing structure. As Figure 4 shown, optionally, the elastic structure can also extend along a preset broken line to form the first abutting portion 101 and / or the second abutting portion 102.

[0084] Optionally, the elastic structure extends along a preset trajectory to form the first abutting portion 101 and / or the second abutting portion 102; the preset trajectory includes a preset curve or a preset broken line.

[0085] Exemplarily, in a digital energy 800V liquid-cooled DCDC (Direct Current to Direct Current) module, the power transistors are arranged in a matrix form. The pressing structure 100 of the embodiment of the present application can be bent along a broken line to form the first abutting portion 101 and the second abutting portion 102. For example, when the power transistors are located on both sides of an S-shaped water channel, the pressing structure 100 can play a role in batch and quickly pressing the symmetric power transistors adjacent to the water channel, with high working efficiency.

[0086] That is to say, the elastic structure of the pressing structure 100 can be two elastic sheets, and after being bent, the first abutting portion 101 and the second abutting portion 102 are formed. The bent outer shape can be in various forms such as corrugations, broken lines, curves, etc., and can adapt to various complex environments.

[0087] It should be further noted that the material of the pressing structure 100 is not limited to materials such as metal and nylon. The force-bearing positions of the first end portion 103 and the second end portion 104 are not limited to structures such as holes, hooks, and lugs.

[0088] Furthermore, the existing "shrapnel + screw" pressing structure is similar to a rigid pressing structure, while the pressing structure 100 in the embodiment of the present application is similar to an elastic pressing structure. That is to say, within the range of elastic potential energy, the pressing structure 100 in the embodiment of the present application can elastically press the target structural member 2 onto the target wall surface 401. The acting force exerted by the pressing structure 100 in the embodiment of the present application on the target structural member 2 can be controlled within the force-bearing range of the target structural member 2 without damaging the target structural member 2 itself.

[0089] It should be further noted that the pressing structure 100 in the embodiment of the present application also allows a certain displacement or deformation of the target structural member 2. Exemplarily, when pressing a power tube onto the target heat dissipation surface of a radiator, the power tube can undergo a certain displacement due to the deformation of the radiator, or the power tube itself can deform due to heat. The target structural member 2 can exert a reaction force on the pressing structure 100 in the embodiment of the present application, thereby changing the first acting force exerted by the first abutting portion on the target structural member 2, and the first abutting portion 101 or the second abutting portion 102 undergoes displacement, so that the pressing structure 100 can adapt to the displacement or deformation of the target structural member 2. This avoids the occurrence of loosening or crushing of the target structural member 2 after being pressed, and avoids the situation where the target structural member 2 cannot work properly due to displacement or deformation.

[0090] Furthermore, for the pressing structure 100 in the embodiment of the present application, after the pressing main body undergoes elastic deformation, the pressing structure 100 only needs to be placed in the gap formed by the target structural member 2 and the supporting wall surface, and the entire installation process is fast and convenient. During the assembly process of the pressing structure 100 in the embodiment of the present application, the number of personnel operation steps is reduced, the processing cycle of the entire product is shortened, the installation is fast and efficient, and it can be applied to the usage scenario of batch delivery. Exemplarily, in an electronic device, a large number of power tubes may need to be pressed. The pressing structure in the embodiment of the present application can reduce the number of personnel operation steps during the power tube assembly process, shorten the assembly cycle of the entire electronic device, and can achieve the task of rapid batch delivery of the electronic device.

[0091] The embodiment of the present application also provides an electronic device, including a target structural member 2 and the pressing structure 100 in the embodiment of the present application. The pressing structure 100 can press the target structural member 2 onto the target wall surface 401.
