[0019] To more clearly illustrate the technical solutions of the embodiments of this specification, the accompanying drawings required for the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some examples or embodiments of this specification. For those of ordinary skill in the art, without creative efforts, this specification can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the figures represent the same structures or operations.
[0020] During the operation of the device, tremors and movements may occur, which may cause the connection parts between the feet and the device body to become loose. For example, fasteners such as bolts and nuts gradually lose their fastening effect, or the adhesive fails due to excessive shear force, thereby increasing the instability and safety hazards during the operation of the device.
[0021] In view of this, some embodiments of this specification provide an anti - detachment foot, which is respectively mated with the housing of the device through the first mating structure and the second mating structure, so that the anti - detachment foot is firmly fixed on the device, preventing the foot from falling off due to the tremors and movements of the device, and the foot is not easily pulled out manually. At the same time, the assembly operation is convenient and simple.
[0022] Figure 1It is a schematic structural diagram of an anti-detachment foot according to some embodiments of this specification.
[0023] As Figure 1 shown, in some embodiments, the anti-detachment foot includes a support body 1, a guiding and pulling-out structure 2, a first matching structure 3, and a second matching structure 4.
[0024] The guiding and pulling-out structure 2 is connected to the support body 1, and the guiding and pulling-out structure 2 is configured to provide guidance for the anti-detachment foot during installation.
[0025] The first matching structure 3 and the second matching structure 4 are provided on the support body 1. The first matching structure 3 protrudes or concaves outward along a first direction, and the second matching structure 4 protrudes or concaves outward along a second direction. The first matching structure 3 and the second matching structure 4 are respectively matched with the housing.
[0026] The support body 1 refers to the main body part of the anti-detachment foot and can bear the pressure of the device.
[0027] The device can be various types of machine devices. For example, audio equipment, mechanical devices, etc. The housing is the housing of the device, which is the outer shell of the device, used to support the device and serve as the installation foundation for the device components. The housing can be made of a variety of feasible materials, such as metal materials, plastics, etc.
[0028] In some embodiments, the shape of the support body 1 can be circular, square, polygonal, and irregular shapes, etc. It should be noted that Figure 1 in which the support body 1 is only for illustration, and the actual shape of the support body 1 may be different from Figure 1 in it.
[0029] In some embodiments, the actual shape of the support body 1 can be set as needed. For example, it can be set accordingly according to the size of the device, the shape of the housing of the device, etc.
[0030] In some embodiments, the support body 1 can be in contact with an external support surface. The external support surface refers to the plane that provides support force for the device. For example, the ground, the desktop, the tabletop, etc.
[0031] In some embodiments, the support body 1 can be arranged outside the housing of the device or can be embedded in the housing of the device.
[0032] In some embodiments, after the support body 1 is in contact with the external support surface, the external support surface can provide a support force for the support body 1, so that the support body 1 can provide a support force for the device, and the device can be placed on the external support surface through the support body 1.
[0033] The guiding and pulling-out structure 2 is a structure for providing installation guidance for the anti-detachment foot.
[0034] In some embodiments, the shape of the guiding and pulling-out structure 2 can be strip-shaped to facilitate clamping and guiding the installation direction.
[0035] In some embodiments, the shape, size, etc. of the guiding and pulling-out structure 2 can be set as needed. For example, it can be set according to the shape of the device housing.
[0036] In some embodiments, the guiding and pulling-out structure 2 can be connected to the supporting body 1 in various ways. For example, it can be connected by at least one of integral molding, snap connection, screw connection, etc.
[0037] In some embodiments, after the guiding and pulling-out structure 2 is connected to the supporting body 1, an installation tool 6 (such as, for example, a pair of needle-nose pliers, etc.) can be used to clamp the guiding and pulling-out structure 2 and move the guiding and pulling-out structure 2 in a predetermined direction (such as Figure 1 the X direction in the figure), so as to drive the supporting body 1 to move until the anti-detachment foot is moved to the installation position.
[0038] The installation position refers to the notch or hole reserved on the device for installing the anti-detachment foot. In some embodiments, the installation position can be set on the side surface and / or the bottom surface of the device housing.
[0039] In some embodiments, the installation position can include an installation opening. The installation opening refers to the notch or hole for accommodating the guiding and pulling-out structure 2. In some embodiments, the installation opening can be set on the device housing or inside the device.
[0040] In some embodiments, after the anti-detachment foot is installed, the guiding and pulling-out structure 2 can be embedded in the installation opening.
[0041] Continuing as Figure 1 shown in the figure, in some embodiments, the supporting body 1 can be fixed to the device housing through a matching structure.
[0042] The matching structure is a structure for restricting the relative movement between the supporting body 1 and the device housing. For example, the matching structure can include at least one of a groove, a protrusion, a pin, etc.
[0043] In some embodiments, the matching structure can include a first matching structure 3 and a second matching structure 4.
[0044] The first matching structure 3 is a matching structure located on the upper surface of the supporting body 1. The second matching structure 4 is a matching structure located on the side surface of the supporting body 1 close to the guiding and pulling-out structure 2.
[0045] In some embodiments, the first mating structure 3 and the second mating structure 4 can be respectively mated with the housing of the device. After the first mating structure 3 and the second mating structure 4 are respectively mated with the housing, the movement of the support body 1 relative to the device can be restricted.
[0046] In some embodiments, the first mating structure 3 can protrude or recess outward in the first direction. In some embodiments, the device housing can correspondingly have an inward recess or outward protrusion in the first direction that matches the first mating structure 3. That is, the outward protrusion of the first mating structure 3 mates with the inward recess of the device housing, or the inward recess of the first mating structure 3 mates with the outward protrusion of the device housing, thereby restricting the movement of the support body 1 relative to the device housing in the first direction. Among them, the first direction can be Figure 1 the Y direction shown in. In some embodiments, the first direction can be the vertical direction.
[0047] In some embodiments, the second mating structure 4 can protrude or recess outward in the second direction. In some embodiments, the device housing can correspondingly have an inward recess or outward protrusion in the second direction that matches the second mating structure 4. That is, the outward protrusion of the second mating structure 4 mates with the inward recess of the device housing, or the inward recess of the second mating structure 4 mates with the outward protrusion of the device housing, thereby restricting the movement of the support body 1 relative to the device housing in the second direction. Among them, the second direction can be Figure 1 the X direction shown in. In some embodiments, the second direction can be the horizontal direction. In some embodiments, the first direction can be perpendicular to the second direction.
[0048] In some embodiments, the first mating structure 3 and the second mating structure 4 respectively restrict the movement of the support body 1 relative to the device housing in the first direction and the second direction, so that when the anti-detachment foot is pulled by an external force, it is not easily detached from the device housing. In some embodiments, after the anti-detachment foot is installed, in the third direction, the support body 1 is restricted by the inner wall of the housing, so that the anti-detachment foot cannot move relative to the device housing in the third direction. Among them, the third direction can be Figure 1 the direction facing out of the paper surface shown in. In some embodiments, the third direction, the first direction, and the second direction are perpendicular to each other in pairs.
[0049] In some embodiments of this specification, through the combined design of the support body, the guiding and pulling-out structure, and the mating structure, not only provides a stable support and accurate installation guidance for the device, but also effectively prevents the problem of the foot moving or falling off during use, thereby significantly improving the reliability and use safety of the device.
[0050] In some embodiments, magnet blocks (not shown in the figure) can be provided inside the first mating structure 3 and the second mating structure 4.
[0051] In some embodiments, when the first mating structure 3 and the second mating structure 4 are convex, the magnet block can be disposed in the convex portion.
[0052] In some embodiments, when the first mating structure 3 and the second mating structure 4 are concave, the magnet block can be disposed on the inner walls of the first mating structure 3 and the second mating structure 4.
[0053] In some embodiments, the shape, size, etc. of the magnet block can be set as needed, for example, according to the sizes of the first mating structure 3 and the second mating structure 4.
[0054] In some embodiments, the device housing can be made of a metal material. When the device housing made of the metal material comes into contact with the anti-detachment feet, the magnet block can provide an additional adsorption force, so that the anti-detachment feet are firmly fixed on the device housing.
[0055] In some embodiments, the device housing can be provided with magnet blocks that are respectively adsorbed to the magnet blocks disposed in the first mating structure 3 and the second mating structure 4, so that the anti-detachment feet are firmly fixed on the device housing.
[0056] In some embodiments of this specification, by providing the magnet blocks, the anti-detachment feet can be adsorbed to the device housing to enhance the connection strength, and it is not easy to fall off during the operation and movement of the device.
[0057] Figure 2 It is a schematic structural diagram of the first mating structure 3 shown in some embodiments of this specification.
[0058] As Figure 2 shown, in some embodiments, the first mating structure 3 can be a groove, and the first mating structure 3 is concave along a first direction.
[0059] In some embodiments, the housing of the device can correspondingly have a first convex portion 31 along the first direction that matches the groove of the first mating structure 3.
[0060] After the anti-detachment feet are installed on the device housing, the first convex portion 31 can be embedded in the first mating structure 3 to limit the movement of the anti-detachment feet relative to the device housing in the first direction.
[0061] In some embodiments, the first mating structure 3 can be located on the upper surface of the support body 1 close to the guiding and pulling-out structure 2. In some embodiments, the first mating structure 3 can be connected to the guiding and pulling-out structure 2.
[0062] In some embodiments of the present specification, by designing the first mating structure as a groove and mating it with the first convex portion of the device housing, it is ensured that the anti-detachment feet are not prone to movement or loosening after installation. And under the action of the gravity of the device, the feet are further compressed, making the fit between the groove and the protrusion tighter, which can effectively resist external vibration and impact, and further improve the stability and reliability of the device operation.
[0063] Continuing as Figure 2 shown, in some embodiments, one side of the first mating structure 3 close to the guiding and pulling-out structure 2 is connected to the upper surface of the guiding and pulling-out structure 2 through an arc transition section 5.
[0064] In some embodiments, the arc transition section 5 can be a partial cylinder. For example, the arc transition section 5 can be a quarter cylinder. One of the two adjacent planes of the quarter cylinder is connected to the support body 1, and the other serves as the inner wall of the groove forming the first mating structure 3, and the arc-shaped surface of the quarter cylinder forms an arc-shaped transition. Among them, the connection manner between the arc transition section 5 and the support body 1 can be bonding, threaded connection, integral molding, etc. In some embodiments, the arc formed by the arc transition section 5 can be bent towards the direction of the first mating structure 3.
[0065] In some embodiments, the size of the arc transition section 5 can be set as needed. For example, it can be set based on the sizes of the first mating structure 3 and the guiding and pulling-out structure 2.
[0066] By providing the arc transition section, when installing the feet by pulling the guiding and pulling-out structure along the second direction, the first convex portion of the device housing can smoothly pass through the arc transition section and then enter the groove to mate with the first mating structure, reducing the installation difficulty and ensuring a firm installation.
[0067] Figure 3 is a schematic structural diagram of the arc transition section 5 shown in some embodiments of the present specification.
[0068] As Figure 3 shown, in some embodiments, the arc transition section 5 can include a first arc 51 and a second arc 52.
[0069] In some embodiments, the first arc 51 is close to the guiding and pulling-out structure 2, and the arc formed by the first arc 51 can be bent towards the direction of the guiding and pulling-out structure 2.
[0070] In some embodiments, the second arc 52 is away from the guiding and pulling-out structure 2, and the arc formed by the second arc 52 can be bent towards the direction of the first mating structure 3.
[0071] During the installation of the anti - detachment foot, the first convex part 31 will first contact the first arc 51 and be resisted by the first arc 51, and then move from the first arc 51 to the second arc 52. The first arc 51 bends towards the direction of the guiding and pulling - out structure 2, which can prevent the resistance received by the first convex part 31 from suddenly changing when it first contacts the first arc 51. Instead, the resistance gradually increases, enabling the first convex part 31 to smoothly move onto the first arc 51.
[0072] In some embodiments of this specification, by providing two arcs, the movement of the first convex part is made more smooth, which can reduce the wear of the anti - detachment foot and increase its service life.
[0073] Continue as Figure 3 shown, in some embodiments, the tangent slope of the first arc 51 at the contact point A with the upper surface of the guiding and pulling - out structure 2 can be the same as the slope of the upper surface of the guiding and pulling - out structure 2, and the tangent slope of the first arc 51 and the second arc 52 at their contact point B can be the same.
[0074] The same tangent slope ensures that the surface normal directions at the contact point A between the first arc 51 and the upper surface of the guiding and pulling - out structure 2 and at the contact point B between the first arc 51 and the second arc 52 are continuous, avoiding sudden changes in the movement resistance of the first convex part 31 at these two contact points.
[0075] In some embodiments of this specification, by smoothly connecting the guiding and pulling - out structure, the first arc, and the second arc in sequence, it can be ensured that the anti - detachment foot moves smoothly during installation, which can further reduce the wear of the anti - detachment foot and increase its service life.
[0076] Figure 4 is a schematic structural diagram of the second mating structure 4 shown according to some embodiments of this specification.
[0077] As Figure 4 shown, in some embodiments, the second mating structure 4 can be a groove, and the second mating structure 4 can be concave inward along the second direction.
[0078] For more descriptions about the second direction, refer to the relevant descriptions in Figure 1 .
[0079] In some embodiments, the device housing can correspondingly have a second convex part 43 along the second direction that matches the groove of the second mating structure 4.
[0080] After the anti - detachment foot is installed on the device housing, the second convex part 43 can be embedded in the second mating structure 4 to restrict the movement of the anti - detachment foot relative to the device housing in the second direction.
[0081] In some embodiments, the second mating structure 4 may be located on the side of the support body 1 where the guiding and pulling-out structure 2 is connected.
[0082] In some embodiments of this specification, by designing the second mating structure as a groove and mating it with the second convex portion of the device housing, it is ensured that the anti-detachment feet are not prone to movement or loosening after installation. And under the action of the device gravity, the feet will be further compressed, making the fit between the groove and the protrusion tighter, and effectively resisting external vibrations and impacts in the second direction, improving the stability and reliability of the device operation.
[0083] Continue as Figure 4 As shown, in some embodiments, the length of the lower surface 42 of the second mating structure 4 may be greater than the length of its upper surface 41.
[0084] After the anti-detachment feet are installed, the lower surface of the second mating structure will be stressed more frequently. By increasing the length of the lower surface, it helps to increase the durability of the anti-detachment feet.
[0085] In some embodiments, the anti-detachment feet may be made of a flexible material. For example, the anti-detachment feet may be made of silicone material, and the silicone material has a relatively high elastic modulus and flexibility. The anti-detachment feet may also be made of other feasible flexible materials, such as rubber, etc.
[0086] In some embodiments of this specification, the anti-detachment feet are made of silicone material, which can effectively absorb and reduce the damage to the device caused by external vibrations. At the same time, when the device is under its own gravity or additional gravity, the flexible feet will be compressed, making the fit between the mating structure and the device housing tighter, further preventing detachment.
