Description

Technical Field

[0001] The present invention relates to the field of electronic technology, and in particular to a mounting bracket and an electronic device. Background Art

[0002] Panel switches, panel sockets, etc. are common panel electrical components and have a wide range of applications.

[0003] In the related art, the panel electrical components are installed in a carrier, such as a wall, through a bottom box. During the installation process, the panel electrical components are placed at the box opening of the bottom box, and screws are inserted through the fixing frame of the panel electrical components and threadedly engaged with the bottom box. By screwing the screws, the panel electrical components can be fixed at the box opening of the bottom box.

[0004] However, during the installation process, if the torque applied to the screws is too large, it is easy to cause the panel electrical components to be deformed or even damaged due to the squeezing of the screws. Summary of the invention

[0005] The disclosed embodiment provides a mounting bracket and electronic equipment, which can effectively prevent the panel electrical components from being deformed during the installation process. The technical solution is as follows:

[0006] In a first aspect, an embodiment of the present disclosure provides a mounting bracket, comprising a support portion, at least two elastic arms, and at least two mounting portions;

[0007] The first end of each elastic arm is connected to the support portion, and the second end of each elastic arm is spaced apart from the support portion;

[0008] The mounting parts correspond to the elastic arms one by one, each mounting part is connected to the second end of the corresponding elastic arm, and each mounting part abuts against each other and together forms a threaded hole;

[0009] The elastic arms are configured such that when the force applied to the mounting portion is greater than a threshold value, each elastic arm produces elastic deformation and drives the mounting portions to move away from each other, so that the inner diameter of the threaded hole increases, and the direction of the force is consistent with the axial direction of the threaded hole.

[0010] In an implementation of the present disclosure, the mounting portions are arranged in sequence along the circumference of the threaded hole, and the direction in which the mounting portions move away from each other is the radial direction of the threaded hole.

[0011] In another implementation of the present disclosure, the mounting portions abut against each other to form a cylindrical structure, the threaded hole is coaxial with the cylindrical structure, and the threaded hole passes through both axial ends of the cylindrical structure.

[0012] In yet another implementation of the present disclosure, each of the elastic arms is respectively connected to an outer peripheral wall of the tubular structural member, and each of the elastic arms is sequentially spaced apart along the circumference of the threaded hole.

[0013] In yet another implementation of the present disclosure, a guide hole is provided between the first end and the second end of the elastic arm;

[0014] The mounting bracket also includes guide arms, which correspond to the elastic arms one by one. The first end of each guide arm is connected to the support portion, and the second end of each guide arm is movably inserted into the corresponding guide hole, and the second end of each guide arm is inclined toward the mounting portion.

[0015] In yet another implementation of the present disclosure, the guide arm and the hole wall of the guide hole are slidably fitted together, and there is line contact between the guide arm and the hole wall of the guide hole.

[0016] In yet another implementation of the present disclosure, the angle between the guide arm and the support portion is less than 90° and greater than or equal to 60°.

[0017] In yet another implementation of the present disclosure, an angle between the elastic arm and the support portion is smaller than an angle between the guide arm and the support portion.

[0018] In yet another implementation of the present disclosure, the mounting bracket further includes a hollow hole;

[0019] The hollow holes correspond to the elastic arms one by one, and the hollow holes are located at the connection between the support part and the corresponding elastic arm.

[0020] In yet another implementation of the present disclosure, the support portion has a perforation;

[0021] The through hole is opposite to the threaded hole.

[0022] In a second aspect, an embodiment of the present disclosure provides an electronic device, including a panel electrical component, a screw, and the mounting bracket described in the first aspect;

[0023] The panel electrical components and the mounting bracket are arranged at intervals;

[0024] The screw passes through the panel electrical component and is inserted into the threaded hole of the mounting bracket, thereby connecting the panel electrical component to the mounting surface.

[0025] The technical solution provided by the embodiments of the present disclosure has the following beneficial effects:

[0026] The mounting bracket is used in electronic devices to cooperate with the installation between the panel electrical components and the bottom box in the electronic devices. During the installation process, the screw penetrates the panel electrical component and is inserted into the threaded hole. As the screw is screwed, the screw moves along the axial direction of the threaded hole until the nut of the screw is tightly against the panel electrical component. At this time, the installation between the panel electrical component and the bottom box has been completed. If the screw is continued to be screwed at this time, the torque on the screw will increase. At the same time, the screw applies a force to the panel electrical component and the mounting part at the same time, and the direction of the force is consistent with the axial direction of the threaded hole. As the torque on the screw continues to increase, the force on the panel electrical component and the mounting part also increases. When the force on the mounting part is greater than the threshold, the elastic arm will produce elastic deformation and drive the mounting parts to move back to each other, so that the inner diameter of the threaded hole increases, and the threaded fit between the threaded hole and the screw is released, and the screw stops applying a force to the panel electrical component and the mounting part, avoiding deformation and damage to the panel electrical component due to excessive force.

[0027] That is to say, when the installation between the panel electrical components and the base box is achieved through the installation bracket provided by the embodiment of the present disclosure, once the torque applied to the screw is too large, causing the force applied to the mounting part to be greater than a threshold value, the threaded fit between the threaded hole and the screw will be released, making it impossible for the screw to continue to apply force to the panel electrical components and the mounting part, thereby effectively protecting the panel electrical components.

DETAILED DESCRIPTION

[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0046] Figure 1 A schematic diagram of the structure of an electronic device provided in an embodiment of the present disclosure is provided. Figure 2 A cross-sectional view of an electronic device, combined with Figure 1 and Figure 2 In this embodiment, the electronic device includes a panel electrical component 200 , a screw 300 and a mounting bracket 400 .

[0047] The panel electrical component 200 and the mounting bracket 400 are arranged at intervals, and the screws 300 penetrate the panel electrical component 200 and are inserted into the threaded holes 40 of the mounting bracket 400, thereby connecting the panel electrical component 200 to the mounting surface.

[0048] It is worth noting that the mounting surface refers to a surface of a carrier on which an electronic device can be mounted. For example, if the carrier is a wall, the mounting surface may be a wall surface; if the carrier is a table, the mounting surface may be a table surface; if the carrier is a cabinet, the mounting surface may be a cabinet surface. The present disclosure does not limit the form of the carrier and the mounting surface.

[0049] In this embodiment, the installation of the electronic device on the installation surface can be completed in conjunction with the bottom box 100. In this case, the bottom box 100 can be regarded as a part of the carrier, and the screws 300 and the bottom box 100 are connected.

[0050] Of course, in other embodiments, the installation of the electronic device on the installation surface can be completed directly by screws 300. In this case, there is no need to cooperate with the bottom box 100, and it is only necessary to have a groove on the installation surface that can accommodate the panel electrical component 200.

[0051] The following description will be made by taking the case of installing electronic equipment in cooperation with the bottom box 100 as an example.

[0052] Exemplarily, the base box 100 is accommodated in a groove on the mounting surface, and a mounting platform 1100 is provided inside the base box 100, one end of the mounting platform 1100 is an open end, and the other end of the mounting platform 1100 is a supporting end, the open end of the mounting platform 1100 is located at the bottom of the base box 100, and the supporting end of the mounting platform 1100 is close to the box opening of the base box 100.

[0053] The panel electrical component 200 is located at the box opening of the bottom box 100. The mounting bracket 400 is located in the mounting platform 1100, and the mounting bracket 400 abuts against the supporting end of the mounting platform 1100. The screw 300 sequentially passes through the panel electrical component 200 and the supporting end of the mounting platform 1100 and is inserted into the mounting bracket 400, and the screw 300 and the mounting bracket 400 are threadedly matched.

[0054] The inner space of the bottom box 100 is used to accommodate the cables of the panel electrical device 200, and the panel electrical device 200 is located at the box opening of the bottom box 100 to close the bottom box 100. The mounting bracket 400 is against the supporting end of the mounting platform 1100, and the screw 300 passes through the panel electrical device 200 and the supporting end of the mounting platform 1100 in sequence and is inserted into the mounting bracket 400. The screw 300 and the mounting bracket 400 are threadedly matched. By screwing the screw 300, the panel electrical device 200 can be fixed at the box opening of the bottom box 100 under the cooperation of the screw 300 and the mounting bracket 400.

[0055] Exemplarily, the panel electrical device 200 is a panel socket, a panel switch, a panel controller, etc., which is not limited in the present disclosure.

[0056] Continue to see Figure 2 In this embodiment, the bottom box 100 further includes a pressure cover 500 , which is located at the open end of the mounting platform 1100 .

[0057] In the above implementation, the gland 500 is used to close the open end of the mounting platform 1100, preventing debris from entering the mounting platform 1100 and affecting the threaded fit between the mounting bracket 400 and the screw 300. In this way, the reliability of the electronic device is effectively improved.

[0058] Exemplarily, the pressure cover 500 includes a cover body 5100 and a support column 5200 . One end of the support column 5200 is connected to the cover body 5100 , and the other end of the support column 5200 abuts against the mounting bracket 400 . The cover body 5100 is located at the open end of the mounting platform 1100 .

[0059] The cover body 5100 and the support column 5200 are an integrated structural component. The cover body 5100 is located at the open end of the mounting platform 1100 and can cover the open end of the mounting platform 1100. The end of the support column 5200 facing away from the cover body 5100 extends into the mounting platform 1100 and abuts against the mounting bracket 400, thereby supporting the mounting bracket 400.

[0060] Figure 3 The schematic diagram of the structure of the mounting bracket is shown in Figure 1. Figure 3 In this embodiment, the mounting bracket includes a supporting portion 10 , at least two elastic arms 20 and at least two mounting portions 30 .

[0061] The first end of each elastic arm 20 is connected to the support portion 10, and the second end of each elastic arm 20 is spaced from the support portion 10. The mounting portions 30 correspond to the elastic arms 20 one by one, and each mounting portion 30 is connected to the second end of the corresponding elastic arm 20. The mounting portions 30 abut against each other and together form a threaded hole 40.

[0062] The elastic arms 20 are configured such that when the force applied to the mounting portion 30 is greater than a threshold value, each elastic arm 20 produces elastic deformation and drives each mounting portion 30 to move away from each other, so that the inner diameter of the threaded hole 40 increases, and the direction of the force is consistent with the axial direction of the threaded hole 40.

[0063] The mounting bracket is used in electronic devices to cooperate with the installation between the panel electrical device 200 and the bottom box 100 in the electronic device. During the installation process, the screw 300 penetrates the panel electrical device 200 and is inserted into the threaded hole 40. As the screw 300 is screwed, the screw 300 moves along the axial direction of the threaded hole 40 until the nut of the screw 300 is tightly against the panel electrical device 200. At this time, the installation between the panel electrical device 200 and the bottom box 100 has been completed. If the screw 300 is continued to be screwed at this time, the torque applied to the screw 300 will increase. At the same time, the screw 300 applies a force to the panel electrical device 200 and the mounting portion 30 at the same time, and the direction of the force is consistent with the axial direction of the threaded hole 40. As the torque applied to the screw 300 continues to increase, the force applied to the panel electrical device 200 and the mounting portion 30 also increases accordingly. When the force applied to the mounting portion 30 is greater than a threshold value, the elastic arm 20 will produce elastic deformation and drive the mounting portions 30 to move away from each other, so that the inner diameter of the threaded hole 40 increases, and the threaded fit between the threaded hole 40 and the screw 300 is released. The screw 300 stops applying force to the panel electrical component 200 and the mounting portion 30, thereby preventing the panel electrical component 200 from being deformed and damaged due to excessive force.

[0064] That is to say, when the installation between the panel electrical component 200 and the base box 100 is achieved by means of the installation bracket provided by the embodiment of the present disclosure, once the torque applied to the screw 300 is too large, causing the force applied to the mounting portion 30 to be greater than a threshold value, the threaded fit between the threaded hole 40 and the screw 300 will be released, making it impossible for the screw 300 to continue to apply force to the panel electrical component 200 and the mounting portion 30, thereby effectively protecting the panel electrical component 200.

[0065] In this embodiment, the threshold value corresponding to the force applied to the mounting portion 30 is a value set manually according to needs. The higher the threshold value, the greater the force applied to the mounting portion 30 required for the elastic arm 20 to produce elastic deformation, and vice versa, the smaller the threshold value, the smaller the force applied to the mounting portion 30 required for the elastic arm 20 to produce elastic deformation.

[0066] Continue to see Figure 3 In this embodiment, the mounting portions 30 are arranged in sequence along the circumference of the threaded hole 40 , and the direction in which the mounting portions 30 move away from each other is the radial direction of the threaded hole 40 .

[0067] That is to say, when the mounting parts 30 move back to back with each other, they move along the radial direction of the threaded hole 40. In this way, the inner diameter of the threaded hole 40 can be quickly increased, and the threaded fit between the threaded hole 40 and the screw 300 can be quickly released, thereby preventing the panel electrical component 200 from being subjected to excessive force for a long time, which is beneficial to protecting the panel electrical component 200.

[0068] In this embodiment, the mounting portions 30 abut against each other to form a cylindrical structure 50 . The threaded hole 40 is coaxial with the cylindrical structure 50 , and the threaded hole 40 passes through both ends of the cylindrical structure 50 in the axial direction.

[0069] In the above implementation, the mutually abutting mounting parts 30 can together form a cylindrical structure 50, the threaded hole 40 is located in the middle of the cylindrical structure 50, and the threaded hole 40 and the cylindrical structure 50 are coaxial with each other. When the mounting parts 30 move back to back, gaps will appear between the mounting parts 30, so that the cylindrical structure 50 becomes a similar cylindrical structure 50. After the mounting parts 30 are reset, they will be restored to form a cylindrical structure 50 together.

[0070] The structure of each mounting portion 30 can be determined according to the number of mounting portions 30. For example, if there are two mounting portions 30, each mounting portion 30 is a semi-cylindrical structure 50, and the openings of the two semi-cylindrical structures 50 are opposite to each other, thereby forming a cylindrical structure 50.

[0071] Exemplarily, the mounting portion 30 of the mounting bracket abuts against the support column 5200 , that is, the end of the cylindrical structure 50 abuts against the support column 5200 , so that the support column 5200 can provide stable support for the mounting portion 30 to facilitate the screw 300 to be inserted into the threaded hole 40 .

[0072] In this embodiment, each elastic arm 20 is connected to the outer peripheral wall of the cylindrical structure 50 , and each elastic arm 20 is arranged in sequence and spaced apart along the circumference of the threaded hole 40 .

[0073] In the above implementation, since the elastic arms 20 are arranged in sequence and spaced apart along the circumference of the threaded hole 40 , it is beneficial for each elastic arm 20 to drive the corresponding mounting portion 30 to move along the radial direction of the threaded hole 40 .

[0074] Exemplarily, the elastic arm 20 includes a first section 220 and a second section 230, the first end of the first section 220 is connected to the first end of the second section 230, the second end of the first section 220 is connected to the support portion 10, the second section 230 extends along the axial direction of the threaded hole 40, one side of the second section 230 is a concave arc surface, the concave arc surface of the second section 230 is connected to the outer peripheral wall of the tubular structure 50, and the first end and the second end of the second section 230 are respectively located at the first end and the second end of the tubular structure 50.

[0075] Such a design can ensure a stable connection between the elastic arm 20 and the cylindrical structure 50 .

[0076] Continue to see Figure 3In this embodiment, a guide hole 210 is provided between the first end and the second end of the elastic arm 20, and the mounting bracket further includes a guide arm 60, the guide arm 60 corresponds to the elastic arm 20 one by one, the first end of each guide arm 60 is connected to the support portion 10, the second end of each guide arm 60 is movably inserted into the corresponding guide hole 210, and the second end of each guide arm 60 is inclined toward the mounting portion 30.

[0077] Figure 4 is a schematic diagram of the moving process of the mounting portion 30, combined with Figure 4 When the mounting portion 30 is subjected to a force, since the guide arm 60 is inserted into the guide hole 210, the elastic arm 20 can be forced to move along the length direction of the guide arm 60 through the cooperation between the guide arm 60 and the guide hole 210, thereby driving the mounting portion 30 to move along the length direction of the guide arm 60. During the movement of the mounting portion 30, the mounting portions 30 will also move away from each other at the same time, so that the inner diameter of the threaded hole 40 increases.

[0078] That is to say, with the cooperation of the guide arm 60 and the guide hole 210 , the movement of the mounting portion 30 can be guided to ensure that the mounting portions 30 can move away from each other, thereby achieving the purpose of increasing the inner diameter of the threaded hole 40 .

[0079] It is worth noting that in order to ensure that the guide arm 60 can force the elastic arm 20 to move along the length direction of the guide arm 60 , the structural strength of the guide arm 60 should be greater than the structural strength of the elastic arm 20 to ensure the reliability of the guide arm 60 .

[0080] Exemplarily, the angle a between the guide arm 60 and the support portion 10 is an acute angle, so as to ensure that the mounting portions 30 can move away from each other under the guidance of the guide arm 60 .

[0081] For example, the angle a between the guide arm 60 and the support portion 10 is less than 90° and greater than or equal to 60°.

[0082] According to the Pythagorean theorem, on the basis that the axial movement stroke of the mounting portion 30 along the threaded hole 40 is constant, the larger the angle a is, the smaller the radial movement stroke of the elastic arm 20 along the threaded hole 40 is; conversely, the smaller the angle a is, the larger the radial movement stroke of the elastic arm 20 along the threaded hole 40 is.

[0083] Exemplarily, the angle a between the elastic arm 20 and the support portion 10 is smaller than the angle b between the guide arm 60 and the support portion 10 .

[0084] Such a design allows the elastic arm 20 to have a larger force arm when swinging about the connection between itself and the support portion 10, so that it can swing to a certain extent after a smaller force is applied to the mounting portion 30, thereby avoiding the elastic arm 20 having a force threshold that is too large to produce elastic deformation.

[0085] In this embodiment, the guide arm 60 and the hole wall of the guide hole 210 are slidably matched, and there is line contact between the guide arm 60 and the hole wall of the guide hole 210 .

[0086] In the above implementation, there is a line contact between the guide arm 60 and the wall of the guide hole 210. On the one hand, it can ensure the contact stability between the guide arm 60 and the wall of the guide hole 210, which is beneficial to the transmission of the force. On the other hand, it can effectively reduce the friction between the guide arm 60 and the wall of the guide hole 210.

[0087] See again Figure 3 In this embodiment, the support portion 10 is a long plate-shaped structural member, the number of the elastic arms 20 is two, the number of the mounting portions 30 is two, and the number of the guide arms 60 is two.

[0088] The two elastic arms 20 are respectively located at the two ends of the support portion 10 and are respectively connected to the ends of the support portion 10. The two mounting portions 30 are respectively connected to the corresponding elastic arms 20, and the two mounting portions 30 abut against each other to form a cylindrical structure 50, and the threaded hole 40 is located in the cylindrical structure 50. The two guide arms 60 are both located between the two elastic arms 20, one end of the two guide arms 60 is connected to the support portion 10, and the other end of the two guide arms 60 is inserted into the guide hole 210 of the corresponding elastic arm 20.

[0089] Of course, in other embodiments, the elastic arms 20 , the mounting portions 30 , and the guide arms 60 may also be other numbers, such as three, four, etc. The shape of the support portion 10 may also be changed accordingly to facilitate the connection of the elastic arms 20 and the guide arms 60 .

[0090] For example, if the number of the elastic arms 20, the mounting portion 30, and the guide arms 60 are all three, then the support portion 10 may be a triangular plate-shaped structural member, and the three elastic arms 20 are respectively connected to the three corners of the support portion 10. The present disclosure is not limited to this.

[0091] Exemplarily, the support portion 10 , the elastic arm 20 , the mounting portion 30 , and the guide arm 60 are an integrated structural component.

[0092] Such a design, on the one hand, ensures the structural integrity of the mounting bracket, which is beneficial to improving the structural strength; on the other hand, it can also improve the manufacturing efficiency of the mounting bracket and reduce the manufacturing cost.

[0093] See again Figure 3 In this embodiment, the support portion 10 has a through hole 80 , and the through hole 80 is opposite to the threaded hole 40 .

[0094] In the above implementation, the through hole 80 is used to accommodate the screw 300, and the screw 300 can penetrate the through hole 80 and then be inserted into the threaded hole 40. In this way, unnecessary interference and collision between the screw 300 and the support part 10 can be effectively avoided.

[0095] Exemplarily, the diameter of the through hole 80 is larger than the diameter of the threaded hole 40 .

[0096] Such a design can facilitate the screw 300 to be inserted into the through hole 80 . After the screw 300 is inserted into the through hole 80 , the through hole 80 can play a certain guiding role for the screw 300 , so that the screw 300 can be further inserted into the threaded hole 40 .

[0097] In other embodiments, in order to avoid unnecessary interference and collision between the screw 300 and the support portion 10 , a notch may be provided on the support portion 10 . The notch is located at the outer edge of the support portion 10 , which can also play a role in avoiding the screw 300 .

[0098] In this embodiment, the mounting bracket further includes hollow holes 70 , which correspond one to one with the elastic arms 20 , and the hollow holes 70 are located at the connection between the support portion 10 and the corresponding elastic arm 20 .

[0099] In the above implementation, since the hollow hole 70 is located at the connection between the support portion 10 and the corresponding elastic arm 20 , the structural strength of the connection is relatively low, which is conducive to the elastic deformation of the elastic arm 20 relative to the support portion 10 .

[0100] It is easy to understand that the threshold value can be adjusted by adjusting the size of the hollow hole 70. The larger the size of the hollow hole 70, the lower the structural strength of the connection between the support part 10 and the elastic arm 20, the easier it is for the elastic arm 20 to produce elastic deformation, and the lower the threshold value. Conversely, the smaller the size of the hollow hole 70, the higher the structural strength of the connection between the support part 10 and the elastic arm 20, the more difficult it is for the elastic arm 20 to produce elastic deformation, and the higher the threshold value.
