Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Figure 1, the present invention provides an elastic solid extrusion assembly structure, including a block 1 and a slot 2, the slot 2 is arranged on a snap-in case 5, and the snap-in case 5 is usually metal Base body, in a specific application scenario, the clamping shell 5 can be an aluminum shell, the clamping groove 2 can be set on the inner wall of the aluminum shell, the clamping block 1 is set on the base 4, and the base 4 and the materials used in the clamping shell 5 are all solid materials with elastic deformation capacity, which can be common plastic materials with relatively large elastic modulus, such as ABS materials, PC materials, PVC materials or Pte materials, also However, it is a common metal material with a small modulus of elasticity, such as aluminum, iron, copper, steel, and the like. Specifically, the block 1 is set on the upper surface of the base 4, and the slot 2 is set on the inner wall of the upper part of the aluminum shell at a position corresponding to the block 1, and is covered from one end of the base 4 through the aluminum shell. Insert, so that the clamping block 1 sinks into the clamping groove 2 to realize the clamping connection between the aluminum shell and the base 4 .

Specifically, a pressure relief groove 3 is also provided at the intersection with the block 1, and the pressure relief groove 3 is arranged close to the periphery of the block 1. Since the base is an elastic member, it is integrally formed with the base 4. When the clamping block 1 is squeezed, the clamping block 1 is deformed and the deformation tendency is transmitted to the periphery of the clamping block 1, and the pressure relief groove 3 is arranged close to the clamping block 1, so that the deformation generated by the clamping block 1 is transmitted When reaching other positions of the substrate, the pressure relief groove 3 provides a deformed accommodation space for the deformed substrate, avoiding the overall deformation of the base 4 due to the cooperation of the block 1 and the slot 2 and affecting the appearance of the product.

Specifically, the block 1 and the pressure relief groove 3 are integrally formed on the base 4, the block 1 is integrally formed on the protrusion on the base 4, and the pressure relief groove 3 is close to the block 1 The provided groove is integrally formed on the base 4. In this embodiment, the base 4 is made of plastic material, and the block 1 and the pressure relief groove 3 can be regarded as formed on the plastic through a mold. Since the function of the pressure relief groove 3 is to release the influence of the deformation on the overall configuration when the block 1 is deformed, the integral molding method is better than the combination molding, so that the mechanical waves caused by extrusion can be efficiently transmitted between the plastic media .

Specifically, as shown in FIG. 2 , a guide slope 6 is provided on the forward direction of the clamping block 1 , and the positive direction refers to the card when the clamping case 5 where the clamping groove 2 is located slides in along the surface of the base 4 . The side of the slot 2 that first contacts the block 1, the guide slope 6 is the side of the block 1 that first comes into direct contact with the snap-in case 5, because in industrial assembly, the snap-in case 5 usually pulls the snap-in slot into place with great force. 2. Push it directly onto the clamping block 1 to form a clamping connection, so the guide slope 6 will generate greater force with the clamping shell 5. Setting the front of the clamping block 1 as a guiding slope 6 can greatly reduce the impact of the clamping shell 5 and the clamping block 1 The damage caused during this process can avoid direct damage to the card block 1 during the card connection process between the card block 1 and the card slot 2.

Specifically, as shown in FIG. 2 , a redundant slope 7 is provided on the back of the block 1 , and the back refers to the opposite surface of the positive direction. The impact deformation caused by the shell 5 on the guide slope 6 will be released to the redundant slope 7 along the forward direction of the clamping shell 5, so as to prevent the deformation of the back surface of the block 1 from affecting the fit between the block 1 and the slot 2.

Specifically, as shown in FIG. 2, a clamping platform 8 is provided between the guide slope 6 and the redundant slope 7, the clamping platform 8, the clamping platform 8 is a plane, and the clamping platform 8 It is used to cooperate with the card slot 2 to realize card connection. Specifically, the width of the clamping platform 8 is close to the width of the clamping groove 2, and the width of the clamping groove 2 is greater than the width of the clamping platform 8. In this embodiment, the width of the clamping groove 2 is 2.5mm, the width of the clamping platform 8 is 2.0mm, since the clamping block 1 is an elastic member, after the clamping block 1 and the clamping shell 5 form an impact, the clamping platform 8 is forcibly embedded in the clamping groove 2, and the impact On the one hand, the generated deformation is released to the surrounding base 4; on the other hand, as shown in Figure 3, the clamping platform 8 changes its own structural shape to adapt to the card slot 2 under the action of deformation, and completely fills the card slot 2. In the groove 2, the clamping connection between the clamping shell 5 and the clamping shell 5 is realized.

Specifically, as shown in FIG. 2 , the clamping slot 2 slides into the clamping platform 8 from the forward direction of the clamping block 1 to realize the clamping assembly, and the extrusion deformation generated by the clamping block 1 during the clamping assembly is released until the pressure is relieved. On the groove 3 and the redundant slope 7, the card slot 2 is set on the clamping shell 5, the clamping block 1 is set on the base 4, and the clamping shell 5 is along the surface of the base 4 from the positive side of the clamping block 1 Slide in the back side of the block 1, that is, slide in from the right to the left in Figure 2. The guide slope 6 of the clamping block 1 first impacts the clamping shell 5, and the deformation generated by the impact is transmitted to the periphery of the clamping block 1, and part of it is released into the pressure relief groove 3, which is specifically shown as the pressure relief groove 3 of the base 4 phase Deformation occurs in the direction of the groove, and the other part is released to the redundant slope 7, specifically manifested as the overall deformation of the block 1, the block 1 receives a downward component force, and a separation from the front to the back of the block 1 , so that the entire clamping block 1 sinks, and at the same time, the redundant slope 7 bulges upward. The clamping shell 5 moves forward after contacting the guide slope 6 until the clamping block 1 sinks into the clamping groove 2 , and the deformed part of the clamping block 1 is filled in the clamping groove 2 , so that the clamping shell 5 and the base 4 fit together completely.

Specifically, the width of the pressure relief groove 3 is proportional to the elastic modulus of the base 4, the length, width and height of the pressure relief groove 3 determine the size of the pressure relief space of the pressure relief groove 3, and the size of the pressure relief space should be According to the adaptive setting of the material of the base 4, for the base 4 with a large elastic modulus, the base 4 will have a large deformation when it is impacted by the snap-fit shell 5, so the size of the pressure relief groove 3 needs to be set accordingly larger, and for the base 4 with a smaller modulus of elasticity, the base 4 undergoes less deformation when impacted by the snap-fit shell 5 , so the size of the pressure relief groove 3 needs to be set smaller accordingly. In this implementation, the length of the pressure relief groove 3 is the same as that of the block 1, and the width and height of the pressure relief groove 3 are adaptively adjusted according to the selection of specific materials. Referring to Fig. 3, in this embodiment, the height from the clamping platform 8 to the surface of the base 4 is greater than the depth of the clamping groove 2, so that the deformation margin of the clamping platform 8 can be completely filled in the clamping groove 2, so that Improve the strength of the combination of the block 1 and the slot 2.

In this embodiment, the clamping block 1 is arranged on the base 4, the clamping shell 5 is pushed along the surface of the base 4, and the position of the clamping block 1 on the base 4 is the same as that of the clamping groove 2 in the clamping shell. The positions on 5 correspond to each other, which means that the closer the clamping block 1 is set on the base 4 to the forward side, the more forward the time point when the clamping shell 5 impacts and contacts with the clamping block 1, then the clamping shell 5 The longer the sliding contact distance between 5 and the clamping platform 8 of the clamping block 1, and the closer the clamping block 1 is arranged on the base 4 to the side facing away, the impact contact between the clamping shell 5 and the clamping block 1 The later the time point is, the shorter the sliding contact distance between the clamping case 5 and the clamping platform 8 of the clamping block 1 is. Since the contact between the clamping housing 5 and the clamping block 1 is accompanied by a huge force impact, the clamping block 1 Being arranged on the side of the base 4 close to the back of the clamping block 1 can shorten the contact time between the clamping block 1 and the clamping shell 5 and reduce damage to the clamping block 1 caused by deformation.

Specifically, referring to FIG. 1 , the pressure relief groove 3 is arranged on the left and right sides where the block 1 intersects. In this embodiment, the block is released by setting the pressure relief groove 3 on the left and right sides of the block 1 1.

In turn, it affects the appearance of the product; by setting a guide slope in the positive direction of the block, it can avoid the force concentration during the cooperation between the block and the slot and damage the block; by setting a redundant slope on the back of the block, the block and the slot During the matching process of the card slot, the extrusion on the guide slope is released to the redundant slope; by setting the card connection platform between the guide slope and the redundant slope, the card connection between the card block and the card slot is realized, and at the same time, the card connection platform and the The redundant space formed between the slopes of the guide slope and the redundant slope reduces the requirements for matching precision between the clamping block and the clamping groove.
