[0042] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0043] Please see Figures 1 to 4 This application provides a locking component 100, which includes a cap 1, a rod 2, and a locking member 3. The cap 1 has a mounting groove 11 and a locking hole 12, with one end of the locking hole 12 extending into the mounting groove 11. The rod 2 is inserted into the mounting groove 11 along a first direction X. The locking member 3 is disposed on the rod 2, and at least part of the locking member 3 is located within the locking hole 12. It is understood that the mounting groove 11 is adapted to the rod 2, so that the rod 2 can only be inserted and removed into the mounting groove 11 in the first direction X. For example, if the rod 2 is flat and rectangular, then the mounting groove 11 is flat and rectangular, and the dimensions of the two are adapted to each other, so that the rod 2 can slide along the first direction X within the mounting groove 11. The locking hole 12 is disposed on the side wall of the mounting groove 11. When the rod 2 is pulled outward, the locking member 3 abuts against the inner wall of the locking hole 12, preventing the rod 2 from disengaging from the mounting groove 11, thereby achieving a locking connection between the rod 2 and the cap 1.

[0044] It should be noted that the cap body 1 is made of a material with low hardness, such as plastic, to improve the comfort of manual operation of the locking component 100. The cap body 1 and the rod body 2 can be integrally injection molded, but the cost is high. In this embodiment, the cap body 1 and the rod body 2 are snap-fitted together, reducing the cost of the locking component 100. Optionally, the rod body 2 is made of metal, such as stainless steel or cast iron.

[0045] In some embodiments, please refer to Figure 1 and Figure 3 The locking hole 12 extends to the outer surface of the cap body 1. The locking member 3 can be pressed from the outside of the cap body 1 to disengage it from the locking hole 12, facilitating the disassembly of the cap body 1 from the rod 2. For example, when the locking member 3 is pressed, it deforms and disengages from the locking hole 12; or the rod 2 deforms, causing the locking member 3 to disengage from the locking hole 12; or the cap body 1 deforms, causing the locking member 3 to disengage from the locking hole 12.

[0046] In some embodiments, please refer to Figure 3 The outer surface of the hat body 1 is provided with anti-slip texture 13 to enhance the anti-slip properties of the hat body 1.

[0047] In some embodiments, please refer to Figure 3 and Figure 4 The locking member 100 also includes a first elastic arm 4, which is disposed on the rod 2. The first elastic arm 4 applies an elastic force toward the first direction X to the inner wall of the mounting groove 11, so that the inner wall of the locking hole 12 abuts against the locking member 3. Exemplarily, the first elastic arm 4 is disposed on the side of the rod 2 facing the first direction X, and abuts against the bottom surface of the mounting groove 11, where the bottom surface of the mounting groove 11 refers to the bottom surface opposite the opening of the mounting groove 11, thereby driving the cap 1 to move relative to the rod 2 along the first direction X, so that the locking member 3 always abuts against the inner wall of the locking hole 12. Thus, when the cap 1 and the rod 2 have manufacturing tolerances, this embodiment improves the problem of the cap 1 wobbling relative to the rod 2 in a direction parallel to the first direction X; furthermore, there is friction between the first elastic arm 4 and the bottom surface of the mounting groove 11, and friction between the locking member 3 and the inner wall of the locking hole 12, improving the problem of the cap 1 wobbling relative to the rod 2 in a direction perpendicular to the first direction X, and improving the problem of the cap 1 being prone to wobbling. Optionally, the first elastic arm 4 is formed by punching from the rod body 2, reducing the overall cost of the first elastic arm 4 and the rod body 2.

[0048] In some embodiments, the rod 2 and the cap 1 are bonded together. Exemplarily, the space between the inner wall of the mounting groove 11 and the rod 2 is filled with adhesive. Optionally, the adhesive is a type of adhesive that can be dissolved by a dissolving agent, such as 502 glue, super glue, instant glue, UV glue, etc.

[0049] Regarding the first elastic arm 4 described above, please refer to some embodiments. Figure 3 and Figure 4 The first end of the first elastic arm 4 is connected to the rod body 2, and the second end of the first elastic arm 4 extends in a direction perpendicular to the first direction X. A boss 41 is provided on the side of the second end of the first elastic arm 4 facing the first direction X, and the boss 41 abuts against the inner wall of the mounting groove 11. By extending the first elastic arm 4 in a direction perpendicular to the first direction X, the length of the first elastic arm 4 in the mounting groove 11 along the first direction X is shortened, and the length of the rod body 2 in the mounting groove 11 along the first direction X is increased, thereby increasing the stability of the connection between the rod body 2 and the cap body 1. Due to manufacturing tolerances, the first elastic arm 4 may have a situation where the first end of the first elastic arm 4 is in contact with the inner wall of the mounting groove 11 while the second end is spaced from the inner wall of the mounting groove 11. This would prevent the first elastic arm 4 from applying an elastic force to the cap body 1. However, by providing a boss 41 at the second end of the first elastic arm 4, this problem of the first elastic arm 4 being unable to apply an elastic force to the cap body 1 can be improved.

[0050] In some embodiments, please refer to Figure 3 and Figure 4The locking member 100 includes two first elastic arms 4 along the second direction Y, which are mirror-symmetrical about the locking member 3; wherein the second direction Y is perpendicular to the first direction X. The two first elastic arms 4 and the locking member 3 apply forces to the cap 1 at three points. Viewed along the third direction Z, the resultant force of the forces exerted by the two first elastic arms 4 on the cap 1 coincides with the force exerted by the locking member 3 on the cap 1, ensuring that the resultant force of the forces exerted by the first elastic arms 4 and the locking member 3 on the cap 1 does not create a torque, thus preventing the cap 1 from tilting or twisting relative to the rod 2. The third direction Z is perpendicular to the first direction X and the second direction Y.

[0051] In some embodiments, along the second direction Y, the width of the rod 2 is equal to the width of the mounting groove 11, and the opposite sides of the rod 2 along the second direction Y abut against the inner wall of the mounting groove 11. By clamping the rod 2 along the second direction Y through the inner wall of the mounting groove 11, the problem of the cap 1 wobbling relative to the rod 2 along the second direction Y is improved. Here, the second direction Y is the width direction of the rod 2, and the third direction Z is the thickness direction of the rod 2. An interference fit between the rod 2 and the cap 1 in the width direction reduces installation difficulty and causes less damage to the cap 1 compared to an interference fit between the rod 2 and the cap 1 in the thickness direction. Therefore, an interference fit between the rod 2 and the cap 1 in the width direction eliminates the need for an elastic arm to form an elastic abutment, reducing the cost of the locking member 100. Optionally, the ratio of the width of the rod 2 along the second direction Y to the thickness of the rod 2 along the third direction Z is greater than or equal to 10.

[0052] In some embodiments, please refer to Figure 3 and Figure 4 The rod 2 has a guide surface 244 on the side facing the first direction X. The guide surface 244 is connected to the side of the rod 2 along the second direction Y. The guide surface 244 is used to guide the rod 2 into the mounting groove 11. For example, the rod 2 includes a first surface 241 and a second surface 242 arranged opposite to each other along the second direction Y. The rod 2 abuts against the inner wall of the mounting groove 11 along the first surface 241 and the second surface 242 parallel to the second direction Y. The rod 2 also includes a third surface 243 facing the first direction X. The guide surface 244 connects the third surface 243 with the first surface 241 or the second surface 242. The angle between the guide surface 244 and the third surface 243 is greater than a flat angle. When the rod 2 is inserted into the mounting groove 11, the guide surface 244 can guide the first surface 241 or the second surface 242 into the mounting groove 11, reducing the difficulty of inserting the rod 2 into the mounting groove 11. Optionally, there are two guide surfaces 244, which are respectively connected to the first surface 241 and the second surface 242. Optionally, the guide surfaces 244 are arc surfaces, and are smoothly connected to at least one of the two opposite sides of the rod 2 along the second direction Y. Optionally, the third surface 243 is located on the first elastic arm 4.

[0053] In some embodiments, please refer to Figure 3 and Figure 4 The locking member 100 also includes a second elastic arm 5. The first end of the second elastic arm 5 is connected to the rod 2, and the second end of the second elastic arm 5 extends in the opposite direction to the first direction X, and also in the opposite direction to the third direction Z. It is understood that the second end of the second elastic arm 5 abuts against the inner wall of the mounting groove 11, and the second elastic arm 5 applies an elastic force to the inner wall of the mounting groove 11 in the opposite direction to the third direction Z, so that the rod 2 is always abutted against the inner wall of the mounting groove 11 along the third direction Z. Thus, when the cap 1 and the rod 2 have manufacturing tolerances, this embodiment improves the problem of the cap 1 wobbling relative to the rod 2 in a direction parallel to the third direction Z. The fact that the second end of the second elastic arm 5 extends in the opposite direction to the first direction X means that when the rod 2 is inserted into the mounting groove 11, the edge of the mounting groove 11 first contacts the first end of the second elastic arm 5, guiding the second end of the second elastic arm 5 into the mounting groove 11, reducing the difficulty of inserting the rod 2 into the mounting groove 11. Optionally, the second elastic arm 5 is formed by punching from the rod body 2, reducing the overall cost of the second elastic arm 5 and the rod body 2.

[0054] In some embodiments, please refer to Figure 3 and Figure 4 The locking member 100 includes two second elastic arms 5 along the second direction Y, and two first elastic arms 4 are mirror-symmetrical about the locking member 3. The two second elastic arms 5 apply forces to the rod 2 on both sides of the locking member 3, so that the rod 2 is stably held against the inner wall of the mounting groove 11 along the third direction Z, and the cap 1 is less likely to tilt or twist relative to the rod 2.

[0055] In some embodiments, please refer to Figure 1 and Figure 3 The snap-fit ​​component 3 is located on the side of the rod 2 facing the third direction Z. In the above embodiment, the second elastic arm 5 drives the rod 2 to always abut against the inner wall of the mounting groove 11 along the third direction Z. In this embodiment, since the snap-fit ​​component 3 is located on the side of the rod 2 facing the third direction Z, the second elastic arm 5 also applies a force toward the snap-fit ​​component 3 toward the snap-fit ​​hole 12, which improves the problem of the snap-fit ​​component 3 easily disengaging from the snap-fit ​​hole 12 and improves the stability of the cap 1 being snapped and connected to the rod 2 through the snap-fit ​​component 3.

[0056] In some embodiments, please refer to Figure 3 and Figure 4The snap-fit ​​component 3 includes a third elastic arm 31. The first end of the third elastic arm 31 is connected to the rod 2, and the second end of the third elastic arm 31 extends in the opposite direction to the first direction X, and also extends in the third direction Z. It is understood that the second end of the third elastic arm 31 abuts against the inner wall of the snap hole 12. The third elastic arm 31 can be pressed from outside the cap 1 to disengage the second end of the third elastic arm 31 from the snap hole 12, facilitating the disassembly of the cap 1 from the rod 2. Optionally, the third elastic arm 31 is punched from the rod 2, reducing the overall cost of the third elastic arm 31 and the rod 2.

[0057] To better understand the working principle of locking element 100, please refer to [link / reference needed]. Figure 5 This application embodiment also provides a power module 200, which includes a module body 210 and a locking member 100. The locking member 100 is disposed on the module body 210 and is used to lock or unlock the module body 210 to the insert frame (not shown). The power module 200 has the structural features and beneficial effects of the locking member 100, which will not be described in detail here.

[0058] Please refer to the following: Figure 3 The rod body 2 includes a connecting part 21, a deformable part 22, an extension part 23 and a fixing part 24 connected in sequence.

[0059] The connecting part 21 is used to connect to the module body 210. Exemplarily, the connecting part 21 is provided with mounting holes, and the connecting part 21 is connected to the module body 210 by screws. Optionally, there can be multiple mounting holes, for example, two.

[0060] The extension 23 has a hook 231 on the side facing away from the third direction Z, and the hook 231 is used to engage with the insert frame. Exemplarily, the insert frame has a groove (not shown) corresponding to the hook 231. When the hook 231 is located in the groove, the locking member 100 prevents the module body 210 from disengaging from the insert frame, thereby locking the module body 210 in the insert frame. The rod 2 can be installed inside the module body 210, and the outer shell of the module body 210 has a through hole corresponding to the hook 231, allowing the hook 231 to extend out of the module body 210. Optionally, the hook 231 is formed by punching and bending from the extension 23.

[0061] The deformable part 22 is used to bend when the fixed part 24 is subjected to force, so that the hook body 231 is away from the insertion frame. When the fixed part 24 is subjected to a force in the third direction Z, the deformable part 22 bends in the third direction Z, so that the hook body 231 is away from the groove; when the hook body 231 is completely away from the groove, the locking member 100 unlocks the module body 210 from the insertion frame.

[0062] The fixing part 24 is inserted into the mounting groove 11. That is, the rod body 2 is connected to the cap body 1 through the fixing part 24, and the snap-fit ​​component 3, the first elastic arm 4 and the second elastic arm 5 are all provided in the fixing part 24.

[0063] In some embodiments, please refer to Figure 3 The connecting portion 21 bends in the opposite direction to the Z-axis relative to the deformable portion 22. This causes both the deformable portion 22 and the extension portion 23 to tend to bend outwards from the module body 210 when the connecting portion 21 is installed on the module body 210, i.e., the hook 231 tends to insert into the groove, thus improving the problem of the structure accidentally leaving the groove and causing locking failure.

[0064] In some embodiments, please refer to Figure 3 and Figure 5 The end of the extension 23 connected to the fixing part 24 is bent in a Z-direction towards a third direction. For example, the end of the extension 23 connected to the fixing part 24 is provided with a stepped bending section 233, which has at least two right-angle bends. The bending section 233 is connected to the fixing part 24, so that the fixing part 24 moves toward the inside of the module body 210, thereby improving the problem of the locking member 100 interfering with the other power module 200.

[0065] In some embodiments, please refer to Figure 3 The extension portion 23 is provided with a reinforcing rib 232. By providing the reinforcing rib 232, the bending resistance of the extension portion 23 is enhanced, so that when the fixing portion 24 is subjected to a force in the third direction Z, the extension portion 23 can drive the deformable portion 22 to bend in the third direction Z, and drive the hook body 231 away from the groove, thus improving the problem that the hook body 231 cannot completely leave the groove due to the bending of the extension portion 23, and therefore cannot unlock the module body 210. Optionally, the reinforcing rib 232 is formed by stamping from the extension portion 23.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
