Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

As shown in Figure 1, a buckle elastic piece is applied to the buckle fixing of related components in the display device, including a support part 1, a first buckle part 2 and a second buckle part 3, the first buckle part 2 The two ends of the support part 1 are respectively extended in the same direction along the two ends of the support part 1. The two ends of the support part 1 are based on the direction shown in the support part 1 in FIG. 1, and the second clamp part 3 faces away from the The first clip part 2 is arched, and during the fastening process, the support part 1 supports the first clip part 2 and the second clip part 3, especially when the second clip part 3 is fastened, Since the second clamping portion 3 is an extension of the supporting portion 1, the second clamping portion 3 is inclined toward the first clamping portion 2 with the starting position of the extension as the base point. , the second card part 3 is also based on the starting position of the extension, so that the second card part 3 can rebound and be in close contact with the contact surface of the fastener; in order to make the fastening process or the disassembly process easier Conveniently, the second card part 3 is arranged in an arched shape, which increases the deformation of the second card part 3, and the deformation is the change of the angle of the second card part 3 relative to the support part 1, and the arched The second clamping portion 3 makes it easier for the fastener to be fastened, and reduces the friction between the fastener and the second clamping portion 3 .

For example, as shown in FIG. 2, the front case 4 and the backboard 5 of the TV set are fixedly connected through the buckle elastic piece. Between the card part 2 and the second card part 3, and in close contact with the first card part 2, the fastening end 41 of the front shell 4 slides along the outer surface 31 of the second card part 3 and When buckled to the end of the second clamping portion 3, the outer side 31 is the side of the second clamping portion 3 facing away from the first clamping portion 2, and during the sliding process of the fastening end 41, the The second clamping part 3 generates certain pressure and frictional force, and the pressure causes the second clamping part 3 to tilt toward the first clamping part 2 based on the starting point of the extension. As the support of the second clamping part 3, at the initial position where the second clamping part 3 extends, the support part 1 gives the second clamping part 3 a supporting force corresponding to and opposite to the pressure at the same time, so that when the fastening end 41 is fastened to the end of the second clamping portion 3, the second clamping portion 3 is no longer subjected to the pressure given by the fastening end 41 and parallel to the support portion 1 , so that under the action of the supporting force of the supporting part 1, the second locking part 3 recovers and deforms.

Further, as shown in FIG. 2, the second clamping portion 3 is arched and relatively straight. When the arched structure is under pressure, it has greater deflection and better deformation. It is not easy to be broken and damaged during card installation or disassembly. Because the arched structure of the second clamping portion 3 is deformed under the action of pressure, when the fastening end 41 of the front shell 4 slides above, a pressure parallel to the support portion 1 is generated, and at the same time, the second clamping portion 3 The friction force parallel to the tangential plane of the contact point is also generated at the contact point, and the pressure causes the oblique deformation of the second clamping part 3, so that the fastening end 41 and the second clamping part 3 will not be so tightly bonded, so the friction force will also be reduced. Smaller, it is easier to buckle the front shell 4 to the end of the second clamping part 3, and at the same time, it will produce less dander. One end of the second clamping portion 3 close to the supporting portion 1 can reserve a gap with the front case 4, so that the connection portion of the plastic frame in the TV structure can be embedded in the gap, thereby stabilizing the components of the entire TV, At the same time, the support part 1 may not be a flat surface, but a shape that can be connected with the rubber frame or other components. Due to the structure of the second clamping part 3, in the process of production, there is no need to reserve a gap for fitting between the end of the second clamping part 3 and the front shell 4. After the installation is completed, the second clamping part 3 The end face of the front shell 4 can be attached to the fitting surface of the front shell 4, so that the relative position of the front shell 4 and the buckle elastic piece can be solidified. The end 41 presses the second clamping part 3, causing the second clamping part 3 to have a certain deformation, and the degree of fit between the second clamping part 3 and the close-fitting surface of the front shell 4 will be reduced, so that the The fastening end 41 of the front shell 4 can be disassembled and installed better, and the service life is improved.

Preferably, in one of the embodiments, the second clamping portion 3 is arc-shaped, and since the arc-shaped structure is more smooth, the fastener can be slid on or removed from the second clamping portion 3 more easily. In order to be smooth, and the center of the arc is located on the side of the first clamping part 2, the second clamping part 3 has a certain amount of elastic deformation when it is clamped and disassembled, and the specific deformation process is as described above. , at least 1/3 of the area of the arc-shaped outer surface 31 fits with the fastener, which is used to ensure that the bonding area between the second clamping part 3 and the fastener is large enough to ensure the stability of the entire buckle shrapnel in the connection structure When the radius of the arc is constant, the length of the arc is also related to the size of the reserved gap. The larger the gap, the greater the length of the arc. For example, the front shell of the TV set 4 and the back plate 5, the area of the outer side 31 of the second clamping part 3 close to 1/2 is in close contact with the bonding surface of the front shell 4, so as to ensure that the buckle elastic piece is opposite to the front shell 4 The solidification of the position ensures the stability after the installation is completed. At the same time, the back plate 5 is snap-fitted and connected with the first clamping part 2 and the support part 1, further stabilizing the buckle elastic piece and the front shell. 4 relative position, to ensure the firmness of the connection between the buckle shrapnel and the front shell 4 and the back plate 5, the first card part 2 and the second card part 3 are connected to the back plate 5 and the front When the shell 4 is buckled and connected, the support part 1 is connected with other structures simultaneously to ensure the firmness of the connection structure of the entire TV set.

Further, as shown in FIG. 1, in another embodiment, the second clamping portion 3 includes a first segment 32 and a second segment 33, and the first segment 32 and the second segment 33 have clips Angle, the angle facing the first clamping portion 2 and is an obtuse angle, on the basis of the foregoing, the second clamping portion 3 is divided into the first segment 32 and the second segment 33, the The second section 33 can fit better on the fitting surface of the fastener.

For example, as shown in FIG. 2 , in the front case 4 of the TV set mentioned above, when the fastening end 41 of the front case 4 is firmly engaged with the second clamping portion 3 , the second The segment 33 is closely attached to the bonding surface of the front shell, and the end of the second clamping part 3 is attached to the fastening end 41 to jointly solidify the relative position between the front shell 4 and the buckle elastic piece. position, and during use, when the ends of the support part 1 and the second clamping part 3 of the buckle elastic piece are pressed toward the center of the buckle elastic piece at the same time, due to the first The clip part 2 is fastened to the backboard 5, and the angle between the support part 1 and the first clip part 2 is matched with the angle between the end face of the connecting section of the backboard 5, so that the buckle elastic piece will not be The connection between the first segment 32 and the second segment 33 of the second clamping part 3 will not be broken when it bounces up, which improves the service life of the buckle elastic piece.

As shown in Figures 1 and 2, the first segment 32 and the second segment 33 have an obtuse angle on the side facing the first clamping portion 2. On the basis of the foregoing, the first segment 32 and the second segment The distance between the front shell 4 is not too large, so that the connection between the buckle elastic piece and the front shell 4 and the back plate 5 is not firm, while maintaining the elasticity of the buckle elastic piece, so that the buckle elastic piece The front shell 4 can be easily snapped and disassembled with the buckle elastic piece. When snapped or disassembled, the second section 33 is subjected to a force parallel to the support part 1 and directed to the first clip part 2. When the pressure is applied, the second section 33 first takes the joint with the first section 32 as the base point, tilts toward the first locking part 2 and produces a certain deformation, and at the same time drives the first section 32 to move toward the first section 32. A clamping portion is inclined and produces a certain amount of deformation, and the base point of the first segment is the initial extension point of the second clamping portion 3 on the support portion 1, and the first segment 32 is subjected to a force parallel to the support portion 1. When the pressure is pointing to the first clamping part 2, the first segment 32 takes the initial extension point of the second clamping part 3 on the support part 1 as the base point, and drives the second segment to the The first clamping portion 32 is inclined. When the aforementioned pressure is not applied, the first section 32 and the second section 33 can recover and deform, so that the second section 33 can be in close contact with the front shell 4. The joint surface is closely attached to ensure the stability of the connection between the buckle shrapnel and the front shell 4 and the back plate 5, so as to realize the elastic effect of the buckle shrapnel. The backboard 5 is connected, and the support part 1 receives the supporting force from the backboard 5 at the same time.

Preferably, as shown in FIG. 1 , the second section 33 is connected with the first section 32 in a circular arc transition, so that the process of clamping and dismounting is smoother, and less burrs are generated during the process of clamping and dismounting. For example, as shown in FIG. 2 , in order to generate less lint during the clamping or dismounting process of the front shell 4 and the back plate 5 , the fastening end 41 of the front shell 4 slides to the first section 32 When connecting with the second segment 33, the circular arc connection enables the fastening end 41 to easily slide from the first segment 32 to the second segment 33, or enables the fastening end 41 to easily slide from the first segment 32 to the second segment 33. The second segment 33 slides to the first segment 32. Since there is no sharp edge, the fastening end 41 will not be scratched during the sliding process, which reduces the generation of dandruff.

Preferably, as shown in FIG. 2, the second section 33 is closely attached to the contact surface of the fastener, such as the front case 4 and the back plate 5 of the TV set mentioned above, and the second section 33 is closely attached to the front case The bonding surface of 4 is beneficial to maintain the solidification of the positions of the front shell 4, the back plate 5, and the buckle shrapnel and the firmness of the connection after the snap-fitting is completed.

Preferably, as shown in FIG. 2 , the included angle between the first clamping part 2 and the supporting part 1 corresponds to the end face angle of the fastening end of the fastening structure. As in the previous example, the back plate 4 and the The buckle shrapnel connection is more stable, which further makes the cooperation between the structures more stable and firm, and increases the firmness of the device using this cooperation method.

Further, the second card part 3 is provided with a hem 34 for being fastened by a fastener, and the side of the fold 33 is folded up relative to the first card part 2, and the hem is provided so that the second card part 3 and the second card part 3 The contact area of the mating connection surface of the fastener is larger, so that the connection structure is more reliable and stable.

Preferably, the folded edge 34 is connected with the second card part 3 in a circular arc transition, and the circular arc transition connection makes the fastener slide from the second clamp part 3 to the folded edge, reducing friction and friction generated by sliding. For example, the connection between the front shell 4 and the back plate 5 of the aforementioned TV set is realized through the buckle elastic piece. , if the transitional connection is a sharp edge, the sharp edge will scrape the buckle end during clamping, thereby generating lint, and at the same time, a relatively large force is required to make the buckle end 41 slide over the sharp edge Fitting with the folded edge 34, when disassembling, it needs a relatively large force to break the fastening end 41 of the front shell 4 over the sharp edge, so that the fastening end 41 can be disassembled to the second locking part, and At the same time, it is also easy to damage the front shell 4, and the circular arc transition is adopted. When clamping, there is no sharp edge, and less or no dander is generated, and the buckle end 41 will not slide to the folded edge. 34 creates an obstacle. When disassembling, the buckle end 41 can also easily pass through the arc segment and slide from the folded edge 34 to the second clamping part 3, and the transition of the arc can be clearly compared. Advantages, and the area of the folded edge 34 relative to the cross section of the second clamping portion 3 is large, so that the contact area between the second clamping portion 3 and the front shell 4 increases, which improves the firmness of the entire device. In addition, the folded edge 34 The area is large, and the hem 34 will not block or scratch the fastening end 41 during disassembly, so that the front shell 4 can be disassembled smoothly. Among them, the aforementioned second locking part 3 The cross section is the cross section of the second clamping portion 3 parallel to the folded edge 3 and not inside the folded edge 34 .

In one of the implementations, in order to better disassemble the fastener, such as the aforementioned front case 4 of the TV set, the end of the folded edge 34 is set at an acute angle, and the edge of the acute angle deviates from the fastener or the buckle of the front case 4 Connecting end 41, so that the hem hinders the disassembly of the fastener or the fastening end 41.

In other embodiments, the folded edge 34 deviates from the support portion 1, so that the angle between the folded edge 34 and the second clamping portion 3 is less than 90°, and the transition connection arc is located at the One side of the edge 34 can be fitted with the fastener, or as mentioned above, be fitted with the fastening end 41 of the front shell 4, so that the buckle elastic piece and the fastener or the front shell 4 can be solidified. At the same time, the disassembly of the fastener is more convenient, or the end of the flange 34 is rounded, and the side of the flange 34 can be completely aligned with the fastener. Fit, also can achieve the purpose of easy disassembly of fasteners.
