Description

Technical Field

[0001] This application relates to the field of multimedia equipment technology, and in particular to a foot pad support structure, housing, and electronic device. Background Technology

[0002] Foot pads, as components installed on the housing of electronic devices, are typically used to support electronic devices on surfaces such as the ground or desktop, to isolate the main body of the electronic device from the contact surface, thereby providing functions such as vibration reduction, noise reduction, insulation protection, and heat dissipation.

[0003] However, in the production process of related technologies, the feet are often connected to the housing of electronic devices only by applying adhesive backing. This results in insufficient weather resistance of the feet. After the feet are subjected to external impact or after long-term use, the adhesive backing is prone to aging, moisture absorption, and other phenomena, which leads to adhesive failure and causes the feet to separate and fall off from the housing. Utility Model Content

[0004] Therefore, it is necessary to provide a foot pad support structure, a housing, and electronic equipment to address the problem that foot pads are prone to separating and falling off from the housing after being subjected to external force or after prolonged use.

[0005] In a first aspect, embodiments of this application provide a foot pad support structure, which includes a housing wall and a support member. The housing wall is provided with a groove, and a boss is provided on the side wall of the groove. The boss is arranged around the circumference of the groove. The support member is assembled to the housing wall and includes a support portion and a snap-fit ​​portion connected to each other. The support portion is located on one side of the boss and at least partially protrudes from the groove. The snap-fit ​​portion is located on the side of the boss away from the support portion.

[0006] In some embodiments, the snap-fit ​​portion includes a central post and a snap-fit ​​wall. One end of the central post is connected to the support portion, and the snap-fit ​​wall is disposed on the outer side wall of the central post and is disposed near the end of the central post away from the support portion. The minimum distance between the snap-fit ​​wall and the support portion is not less than the thickness of the boss.

[0007] In some embodiments, the boss includes a first surface and a second surface opposite each other along the thickness direction, the first surface being disposed close to the support portion; along the periphery of the groove toward the center, the first surface gradually slopes toward the second surface.

[0008] In some embodiments, the snap-fit ​​wall includes a third surface facing away from the support portion, and the third surface gradually slopes away from the support portion in the direction from the periphery of the snap-fit ​​wall toward the center.

[0009] In some embodiments, the central column includes a plurality of sub-columns arranged in a centrally symmetrical manner, with gaps between adjacent sub-columns; the snap-fit ​​wall includes a plurality of sub-walls, with one sub-wall connected to one sub-column.

[0010] In some embodiments, the cross-sectional shape of the sub-pillar is arc-shaped in the direction perpendicular to the connection direction between the support and the snap-fit, and multiple sub-pillars together form a ring structure.

[0011] In some embodiments, the portion of the snap-fit ​​part located on the side of the boss away from the support part is made of an elastomeric material.

[0012] In some embodiments, the support portion and the snap-fit ​​portion are integrally formed.

[0030] Foot pads, as components installed on the housing of electronic devices, are typically used to support electronic devices on surfaces such as the ground or desktop, to isolate the main body of the electronic device from the contact surface, thereby providing functions such as vibration reduction, noise reduction, insulation protection, and heat dissipation.

[0031] However, in the production process of related technologies, the feet are often connected to the housing of electronic devices only by applying adhesive backing. This results in insufficient weather resistance of the feet. After the feet are subjected to external impact or after long-term use, the adhesive backing is prone to aging, moisture absorption, and other phenomena, which leads to adhesive failure and causes the feet to separate and fall off from the housing.

[0032] Based on the above issues, please refer to Figures 1 to 4This application provides a foot pad support structure 100, which is disposed on the housing 1000 of an electronic device so as to contact the support surface (desktop, ground, etc.) when the electronic device is placed, thereby providing stable support and protection.

[0033] In these embodiments of this application, the electronic device can be a television projector, laser television, or other device that needs to be placed on a support surface to operate. The foot support structure is disposed on the housing 1000, generally referring to the foot support structure being disposed on the surface of the housing 1000 that is in contact with the support surface.

[0034] This application provides a foot pad support structure 100, which includes a housing wall 10 and a support member 20. The housing wall 10 is provided with a groove 11, and a boss 12 is provided on the side wall of the groove 11. The boss 12 is arranged around the circumference of the groove 11. The support member 20 is assembled to the housing wall 10 and includes a support part 21 and a snap-fit ​​part 22 connected to each other. The support part 21 is located on one side of the boss 12 and at least partially protrudes from the groove 11. The snap-fit ​​part 22 is located on the side of the boss 12 away from the support part 21.

[0035] The housing wall 10 is a support wall on the housing 1000 to accommodate and support the internal components of the electronic device, and to provide a support member 20, which supports the housing 1000 on the support surface.

[0036] The housing wall 10 is provided with a groove 11, which is used to assemble the support member 20. Generally, the groove 11 is provided on the surface of the housing wall 10 opposite to the support surface, so that after the support member 20 is installed, it is supported on the support surface.

[0037] In these embodiments of this application, the groove 11 can be set as a through groove or a blind groove, so that the support member 20 can be assembled using the internal space of the groove 11.

[0038] The side wall of the groove 11 is provided with a boss 12 so that after the support member 20 is assembled onto the housing wall 10, the groove 11 can be used to provide a space for the support member 20, and the boss 12 can be used as a snap-fit ​​structure with the support member 20. In addition, the boss 12 can be used to restrict the movement of the support member 20 away from the housing wall 10 after the support member 20 is assembled onto the housing wall 10.

[0039] In these embodiments of the present application, a boss 12 is provided on the side wall. In possible implementations, the boss 12 is formed into a ring structure during the molding stage, and the outer contour of the boss 12 is the same as the cross-sectional shape of the groove 11. During the assembly stage, the boss 12 is set on the inner side wall of the groove 11 by a detachable connection method such as a connector or a snap-fit ​​connection. Alternatively, in some embodiments, the boss 12 and the groove 11 can be directly integrally formed.

[0040] The boss 12 is arranged around the circumference of the groove 11. In a possible implementation, the boss 12 is a ring structure that extends continuously around the circumference of the groove 11 to improve the stability and reliability of the support member 20 after it is assembled to the housing wall 10. Alternatively, the boss 12 can also be a multi-segment structure. The multi-segment structure of the boss 12 is arranged sequentially at intervals along the circumference of the groove 11 and is connected end to end, so that the multi-segment structure of the boss 12 together forms a ring structure that is arranged around the circumference of the groove 11.

[0041] The support member 20 is assembled with the housing wall 10, meaning that the support member 20 is assembled with the housing wall 10 through a groove 11 formed on the housing wall 10. In these embodiments of this application, the number of support members 20 provided on a single housing wall 10 may be no less than two, in order to improve the stability of the electronic device placed on the support surface after the support member 20 is assembled.

[0042] The support member 20 includes a support portion 21 and a snap-fit ​​portion 22 connected to each other. The support portion 21 is a structure in the support member 20 for contacting the support surface. Therefore, in these embodiments of the present application, by setting at least a portion of the support portion 21 to protrude from the groove 11, the support portion 21 can contact the support surface when the electronic device is in a static state, thereby providing support and protection for the electronic device using the support portion 21.

[0043] In these embodiments of the present application, the support portion 21 may be made of an elastomeric material to reduce the rigidity of the support portion 21 when it contacts the support surface, thereby providing a buffer and protection for the electronic device.

[0044] The support portion 21 is provided on one side of the boss 12, which means that the support portion 21 is provided on the side of the boss 12 corresponding to the side of the housing wall 10 near the support surface, so that it protrudes from the groove 11 on the side of the housing wall 10 near the support surface, and then contacts the support surface during use.

[0045] The snap-fit ​​part 22 is a structure in the support member 20 used for self-assembly. During the assembly process of the support member 20, the snap-fit ​​part 22 is assembled into the groove 11 and snap-fit ​​with the boss 12 is achieved by using the snap-fit ​​part 22, thus realizing the assembly of the support member 20 and the housing wall 10.

[0046] The snap-fit ​​portion 22 is located on the side of the boss 12 away from the support portion 21. The snap-fit ​​portion 22 located on the side of the boss 12 away from the support portion 21, together with the support portion 21, clamps the boss 12, thereby realizing the assembly of the support member 20 and the housing wall 10.

[0047] It should be noted that the snap-fit ​​part 22 is connected to the support part 21, and part of the snap-fit ​​part 22 has a structure located on the side of the boss 12 away from the support part 21, so that the snap-fit ​​part 22 and the support part 21 can jointly clamp and fix the boss 12.

[0048] Based on this, at least a portion of the snap-fit ​​part 22 is provided in the annular area enclosed by the boss 12, so as to pass through the boss 12 along the thickness direction of the housing wall 10 and connect with the support part 21. At the same time, on the side of the boss 12 away from the support part 21, this portion of the snap-fit ​​part 22 can extend to the periphery so that this portion of the snap-fit ​​part 22 can be snapped onto the side of the boss 12 away from the support part 21, and together with the support part 21, it is clamped on both sides of the boss 12 to realize the assembly of the support member 20 and the housing wall 10.

[0049] According to the foot pad support structure 100 provided in the embodiments of this application, a groove 11 with a boss 12 is provided on the side wall of the housing wall 10, and a support member 20 is provided including a support part 21 and a snap-fit ​​part 22 connected to each other. The snap-fit ​​part 22 is located on the side of the boss 12 away from the support part 21. In this way, the snap-fit ​​part 22 and the support part 21 are snapped together on the boss 12 to realize the assembly of the support member 20 and the housing wall 10. The structure is simple and easy to install, and it can improve the assembly reliability and weather resistance between the support member 20 and the housing wall 10, and reduce the risk of the support member 20 separating and falling off after being subjected to external impact or after long-term use.

[0050] In some embodiments, the snap-fit ​​portion 22 includes a central post 221 and a snap-fit ​​wall 222. One end of the central post 221 is connected to the support portion 21. The snap-fit ​​wall 222 is disposed on the outer side wall of the central post 221 and is disposed near the end of the central post 221 away from the support portion 21. The minimum distance between the snap-fit ​​wall 222 and the support portion 21 is not less than the thickness of the boss 12.

[0051] The snap-fit ​​part 22 includes a central post 221 and a snap-fit ​​wall 222. The central post 221 is the part of the snap-fit ​​part 22 used to connect with the support part 21. After the support member 20 is assembled with the housing wall 10, the central post 221 is set in the annular area enclosed by the boss 12, and its two ends are respectively connected to the support part 21 and the snap-fit ​​wall 222 located on both sides of the boss 12.

[0052] In these embodiments of this application, the plane where the support portion 21 is located can be set parallel to the plane where the snap-fit ​​wall 222 is located, and the two ends of the central column 221 are respectively connected to the center of the snap-fit ​​wall support portion 21 and the center of the snap-fit ​​wall 222. In this way, during the working stage of the foot pad support structure 100, the support portion 21 deforms after contacting the support surface. Since the two ends of the central column 221 are respectively connected to the center of the snap-fit ​​wall support portion 21 and the center of the snap-fit ​​wall 222, the force on the support member 20 is evenly distributed in the circumferential direction, further reducing the risk of the support member 20 separating and falling off.

[0053] The snap-fit ​​wall 222 is provided on the outer side wall of the central post 221. In a possible implementation, the snap-fit ​​wall 222 can be integrally formed with the central post 221 to improve the structural consistency of the snap-fit ​​part 22.

[0054] The snap-fit ​​wall 222 is located near the end of the central column 221 away from the support part 21. The minimum distance between the snap-fit ​​wall 222 and the support part 21 is not less than the thickness of the boss 12, so as to form a sufficiently large gap between the snap-fit ​​wall 222 and the support part 21. After the support member 20 is assembled, the boss 12 can be snapped into the gap to improve the structural stability of the foot pad support structure.

[0055] One end of the central column 221 is connected to the support part 21. In a possible implementation, one end of the central column 221 can be connected to the support part 21 by a detachable connection method such as threaded connection or snap-fit ​​connection, so as to reduce the assembly difficulty of the support part 20 and facilitate replacement during subsequent use; or, one end of the central column 221 can be fixedly connected to the support part 21 by means of adhesive or integral molding, so as to further improve the structural consistency of the support part 20.

[0056] In some embodiments, the boss 12 includes a first surface 121 and a second surface 122 that are opposite each other in the thickness direction. The first surface 121 is disposed close to the support portion 21. Along the periphery of the groove 11 toward the center, the first surface 121 gradually tilts toward the second surface 122.

[0057] The first surface 121 being located near the support portion 21 means that, in the state where the support member 20 is assembled, the first surface 121 is the surface of the boss 12 located near the support portion 21.

[0058] In some embodiments, the portion of the snap-fit ​​portion 22 located on the side of the boss 12 opposite to the support portion 21 is made of an elastomeric material. That is, the snap-fit ​​wall 222 can be made of an elastomeric material. It should be noted that the aforementioned elastomeric material in this application can be, but is not limited to, silicone, rubber, or other materials that can undergo elastic deformation when subjected to external force.

[0059] In this way, during the process of assembling the support member 20 to the housing wall 10, the elastic deformation characteristic of the snap-fit ​​part 22 can be utilized to press the snap-fit ​​wall 222 through the side of the boss 12 near the first surface 121 into the area enclosed by the boss 12, so that the snap-fit ​​wall 222 rebounds after being pressed through the boss 12 and is locked on the side of the boss 12 near the second surface 122.

[0060] In these embodiments of the present application, by setting the first surface 121 to gradually tilt toward the second surface 122 in the direction from the periphery of the groove 11 toward the center, the first surface 121 can be used as a guide surface to press the snap-fit ​​wall 222 toward the other side of the boss 12, so as to guide the snap-fit ​​wall 222 to gradually deform under the pressing action, which helps to reduce the assembly difficulty of the support member 20.

[0061] In some embodiments, the snap-fit ​​wall 222 includes a third surface 2221 that is away from the support portion 21. Along the periphery of the snap-fit ​​wall 222 towards the center, the third surface 2221 gradually tilts away from the support portion 21.

[0062] Accordingly, in these embodiments of this application, the third surface 2221 can be gradually inclined away from the support portion 21 in the direction from the periphery of the snap-fit ​​wall 222 toward the center, so that the shape of the snap-fit ​​portion 22 in the direction of being squeezed matches the shape of the boss 12, forming a structure with a small front end and a gradually increasing rear end. This is beneficial for the snap-fit ​​wall 222 to gradually deform under the squeezing action, which can reduce the risk of the snap-fit ​​portion 22 breaking during the squeezing process through the boss 12, and improve reliability.

[0063] In some embodiments, the central column 221 includes a plurality of sub-columns 2211 arranged in a centrally symmetrical manner, and there is a gap 101 between adjacent sub-columns 2211; the snap-fit ​​wall 222 includes a plurality of sub-walls 2222, and one sub-wall 2222 is connected to one sub-column 2211.

[0064] The central column 221 includes multiple sub-columns 2211 arranged in a centrally symmetrical manner, meaning that the central column 221 is composed of multiple sub-columns 2211 arranged in a centrally symmetrical manner, and the structure of each sub-column 2211 is independent and can undergo elastic deformation independently.

[0065] There is a gap 101 between adjacent sub-pillars 2211 so that when the end of the multiple sub-pillars 2211 away from the support part 21 is squeezed by the snap-fit ​​part 22, it can deflect towards the center. Since the snap-fit ​​wall 222 is set at the end of the central column 221 away from the support part 21, after the multiple sub-pillars 2211 deflect towards the center, the gap between the multiple sub-walls 2222 can be reduced simultaneously, thereby reducing the cross-sectional area of ​​the snap-fit ​​wall 222 as a whole. This further reduces the difficulty of the snap-fit ​​wall 222 passing through the boss 12 under the squeezing action, resulting in better reliability.

[0066] In these embodiments of this application, the number of sub-pillars 2211 may be set to two, three, four, etc.

[0067] In some embodiments, the cross-sectional shape of the sub-pillar 2211 is arc-shaped in the direction perpendicular to the connection direction between the support portion 21 and the snap-fit ​​portion 22, and multiple sub-pillars 2211 together form a ring structure.

[0068] In these embodiments of the present application, by setting the cross-sectional shape of the individual sub-pillar 2211 in the direction perpendicular to the connection direction between the support portion 21 and the snap-fit ​​portion 22 to be arc-shaped, the difficulty of the individual sub-pillar 2211 deflecting when subjected to external force can be reduced, and more space is provided at the center position for the sub-pillar 2211 to undergo elastic deformation, which is beneficial to improving the performance of the snap-fit ​​portion 22 passing through the boss 12 under the action of compression.

[0069] Multiple sub-pillars 2211 together form a ring structure so that after the snap-fit ​​part 22 passes the boss 12, the sub-walls 2222 can be evenly distributed around the central pillar 221, so that the snap-fit ​​force between the snap-fit ​​part 22 and the boss 12 is evenly distributed in the circumferential direction, further reducing the risk of the support member 20 separating and falling off when subjected to external force.

[0070] Secondly, embodiments of this application also provide a housing 1000, which includes a foot support structure 100 as provided in any of the foregoing embodiments. The housing 1000 has an accommodating space, and the foot support structure 100 is disposed on the side of a wall structure of the housing 1000 opposite to the accommodating space, so that the housing 1000 can contact the supporting surface using the foot support structure 100, thereby improving the structural stability and reliability of the components stored in the accommodating space.

[0071] Thirdly, embodiments of this application also provide an electronic device, which includes a housing 1000 as provided in any of the foregoing embodiments.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
