[0033] Example 1

[0034] The present embodiment provides a fixing structure to solve the problems in the related art that the fixing method of the sheet metal parts is complicated and cumbersome, and it is difficult to disassemble after the fixing process.

[0035] See also Figure 1 , Figure 4 and Figure 5A fixing structure is used to fix a sheet metal part 300. The fixing structure includes a frame 100 and a clamping assembly 200. The clamping assembly 200 includes an elastic element 210 and a non-return element 220, wherein the elastic element 210 is disposed on the frame 100, and the non-return element 220 is disposed on the elastic element 210. A fixing hole 110 is provided on the sheet metal part 300. The elastic element 210 can drive the non-return element 220 to be inserted into the fixing hole 110, and the non-return element 220 can abut against the sheet metal part 300, and the elastic element 210 can abut the sheet metal part 300 against the frame 100 through the non-return element 220.

[0036] Specifically, when using the fixing structure of the present embodiment, the frame 100 is controlled so that the elastic element 210 on the snap-on assembly 200 can be inserted into the fixing hole 110 on the sheet metal 300. After the elastic element 210 is inserted into the fixing hole 110, the operator applies an external force to the elastic element 210 so that the non-return element 220 on the elastic element 210 abuts against the sheet metal 300. The non-return element 220 cooperates with the frame 100 to abut the sheet metal 300 between the non-return element 220 and the frame 100, and the fixing is completed.

[0037] It is understandable that the shape of the elastic element 210 can be arbitrarily set according to the shape of the fixing hole 110, as long as the elastic element 210 can match the fixing hole 110. In addition, when the sheet metal part 300 itself carries a hole of any shape, it is not necessary to open the fixing hole 110 when fixing it. The elastic component can adaptively set the shape to a corresponding shape to fix the sheet metal part 300. Furthermore, if the sheet metal part 300 is not provided with a hole or it is not suitable to open a hole, the fixing structure of this embodiment can also be set at the edge of the sheet metal part 300. By abutting the edge of the sheet metal part 300 between the non-return element 220 and the frame 100, the sheet metal part 300 is fixed, thereby improving the practicality of this embodiment.

[0038] In some embodiments, for example, Figures 1 to 3 As shown, the elastic element 210 includes an elastic rod, and the elastic rod is arranged on the frame 100. At least two elastic rods are arranged on the frame 100, and at least one of the elastic rods is provided with a non-return element 220. When the multiple elastic rods are away from each other, the non-return element 220 can abut against the sheet metal part 300. In this way, after the elastic rods extend into the fixing holes 110, only external force needs to be applied to make the multiple elastic rods move away from each other, and the sheet metal part 300 can be fixed by the non-return element 220, so that the fixing process of this embodiment is simple and convenient.

[0039] In some embodiments, for example, Figure 1 , Figure 4 , Figure 5As shown, a through hole is provided on the frame 100, and a limiting member is inserted into the through hole. The limiting member extends between the multiple elastic rods, and the limiting member can make the multiple elastic rods move away from each other. After the elastic rod extends into the fixing hole 110 and extends to a suitable position, the limiting member is inserted into the through hole and extends between the multiple elastic rods. The limiting member can push the multiple elastic rods to a direction away from each other, thereby enabling the non-return element 220 to abut against the sheet metal part 300 and fix the sheet metal part 300. The matching of the limiting member and the through hole can make the installation process of this embodiment simpler. During installation, it is only necessary to insert the elastic rod into the suitable position in the fixing hole 110 and insert the limiting member into the through hole, which reduces the difficulty of using this embodiment and enables any operator to use it normally.

[0040] In some embodiments, for example, Figure 1 , Figure 4 As shown, an internal thread is provided in the through hole, and the stopper is set as a screw 130, which can cooperate with the internal thread and pass through the through hole. The screw 130 can abut on the elastic rod and make multiple elastic rods move away from each other. After the elastic rod is extended to a suitable position, the screw 130 is screwed into the through hole. As the screw 130 gradually extends into the through hole, the elastic rod can be moved in a direction to move away from each other, and the elastic member is elastically deformed to a suitable position, so that the non-return element 220 abuts against the sheet metal part 300. An internal thread is provided in the through hole, and the stopper is set as the screw 130, so that when the screw 130 is extended into the through hole, it can be made to stay at any position through thread cooperation, thereby ensuring the deformation degree of the elastic rod, that is, ensuring that the non-return element 220 can properly abut against the sheet metal part 300.

[0041] It can be understood that the elastic rods are elastic parts. When there is no limiter to stretch the multiple elastic rods apart and keep them away from each other, the multiple elastic rods tend to move toward the middle. In this way, the elastic rods can be easily operated when they are inserted into the through holes, and the situation where the end of the elastic rod is close to the diameter of the through hole, which increases the difficulty of insertion, can be prevented.

[0042] In some embodiments, for example, a boss is provided on the frame 100, and a through hole is provided at the center of the boss. In this way, when the screw 130 is installed in the through hole, the boss can position and guide the screw 130, making it easy to install, and the difficulty of installing the screw 130 is reduced by such a foolproof design.

[0043] In some embodiments, for example, Figure 2 , Figure 3 , Figure 5As shown, a threaded portion 211 is provided on one surface of the elastic rod facing another elastic rod, and the threaded portions 211 on multiple elastic rods can be enclosed to form a thread groove. The thread groove is connected to the through hole, and the axis of the thread groove coincides with the axis of the through hole. The threaded portion 211 is provided on the elastic rod, and multiple threaded portions 211 can be enclosed to form a thread groove, so that the screw 130 extends into the through hole and cooperates with the internal thread, and gradually extends toward the direction close to the elastic rod through rotation. The threaded portion 211 can continue to cooperate with the screw 130, thereby improving the reliability of the screw 130 and the through hole, that is, improving the reliability of the fixation of this embodiment. Through the cooperation of the screw 130 and the threaded portion 211, the elastic rod is pushed out in the direction of moving away from each other, which can slow down the deformation speed of the elastic rod, and avoid the elastic rod from being subjected to stress fatigue due to the elastic rod being deformed too fast, thereby affecting the life of this embodiment. In addition, the threaded fit is a more precise fit, and a threaded portion 211 is provided on the elastic rod. That is to say, after the screw 130 is extended to the specified position, the elastic rod will only cooperate with the screw 130 and be in the specified position. The position of the elastic rod will not be changed by external influences and will be in other positions, thereby affecting the abutment between the non-return element 220 and the sheet metal part 300, thereby improving the stability of this embodiment.

[0044] In some embodiments, the elastic rod is exemplarily facing the side of the fixing hole 110, and its shape matches the fixing hole 110, so that after the elastic rod is stretched outward, the non-return element 220 can abut against the sheet metal part 300 to fix the sheet metal part 300 and prevent the sheet metal part 300 from sliding along the elastic rod. In addition, after the elastic rod is stretched out, the side of the elastic rod can abut against the side of the fixing hole 110, and the elastic rod can further restrict the sheet metal part 300 by contacting and squeezing the fixing hole 110, so as to prevent the sheet metal part 300 from shaking after the fixing is completed. The sheet metal part 300 is completely fixed by squeezing the elastic rod and limiting the non-return element 220, thereby improving the reliability of the fixing of this embodiment.

[0045] In some embodiments, for example, Figure 2 , Figure 3 , Figure 5As shown, the length of the through hole is L1, the length of the thread groove is L2, and the length of the screw 130 is L3, which satisfies: L1<L3≤L1+L2. The length of the screw 130 is greater than the length of the through hole, ensuring that the screw 130 can extend out of the through hole when it is inserted into the through hole, and extend between multiple elastic rods to spread the multiple elastic rods apart. The length of the screw 130 is less than the sum of the lengths of the through hole and the thread groove, which can ensure that the end of the screw 130 will not extend out of the thread groove after the screw 130 is inserted into the through hole. On the one hand, it can ensure the effect of the screw 130 on spreading the multiple elastic rods and improve the reliability of this embodiment. On the other hand, the screw 130 can also be protected by the thread groove to prevent the screw 130 from hitting other external structures and affecting the reliability of the fixation, and also prevent the user or operator from accidentally touching the tip of the screw 130, causing harm to the user or operator.

[0046] In some embodiments, for example, Figure 3 As shown, the non-return element 220 includes a wedge block, which is arranged on a side of the elastic element 210 away from another elastic element 210. The end of the wedge block can abut against the sheet metal 300. The non-return element 220 is set as a wedge block. During the process of inserting the elastic rod into the fixing hole 110, the inclined surface of the wedge block can guide the elastic rod to be inserted without affecting the elastic rod. After the elastic rod is inserted into the appropriate position, the end of the wedge block can abut against the sheet metal 300 to fix the position of the sheet metal 300. The wedge block is arranged on the side of the elastic element 210 away from other elastic elements 210, which can ensure that after the elastic rods are deformed and move away from each other, the wedge block will abut against the sheet metal 300 again, avoiding misoperation and improving the convenience of the installation process of this embodiment.

[0047] In some embodiments, for example, Figure 2 , Figure 5 As shown, a stopper 140 is provided on one side of the frame 100 facing the elastic element 210, and the stopper 140 and the non-return element 220 can respectively abut against two side surfaces of the sheet metal part 300. By the cooperation between the stopper 140 and the non-return element 220, the stopper 140 abuts against one side surface of the sheet metal part 300, and the non-return element 220 abuts against the other side surface of the sheet metal part 300, so that the sheet metal part 300 can be completely limited and fixed reliably.

[0048] In some embodiments, for example, a reinforcing rib 120 is provided on one side of the frame 100 away from the elastic element 210. A plurality of reinforcing ribs 120 are provided, and the plurality of reinforcing ribs 120 are evenly distributed on the frame 100. By providing the reinforcing ribs 120 on the frame 100, the strength of the frame 100 is improved, cracks or shaking of the frame 100 during the fixing process of the sheet metal part 300 are prevented, the structural strength of the present embodiment is improved, and the reliability of the fixing operation of the present embodiment is improved.

[0049] It is worth mentioning that the reinforcing ribs 120 on the frame 100 are all connected to the bosses. In this way, the structural strength of the frame 100 can be improved as a whole through the cooperation between the reinforcing ribs 120 and the bosses, further making this embodiment more reliable and durable.

It can be understood that the sheet metal part 300 can be applied to any parts that require sheet metal, such as automobile chassis, automobile body, etc. Correspondingly, the fixing structure can also be set on any parts to cooperate with the sheet metal part 300 to complete the fixing operation.
