[0073] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0074] Reference below Figure 1-Figure 35The retaining spring structure 100 according to an embodiment of the present invention is described. The retaining spring structure 100 can effectively disperse the force on the ball head structure 300 and support the ball head structure 300, making it difficult for the ball head structure 300 to fall out of the ball socket structure 200, thereby improving the installation stability and reliability of the ball head structure 300.

[0075] like Figure 1-Figure 35 As shown, according to a retaining spring structure 100 of an embodiment of the present invention, the retaining spring structure 100 is suitable for being installed in the ball socket structure 200 and cooperating with the ball head structure 300 in a limiting manner, that is, the retaining spring structure 100 can be installed in the ball socket structure 200, and can cooperate with the ball head structure 300 located in the ball socket structure 200 to achieve a limiting effect on the ball head structure 300, thereby limiting the movement range of the ball head structure 300 and preventing the ball head structure 300 from escaping from the ball socket structure 200, thereby ensuring the installation stability and accuracy of the ball head structure 300 in the ball socket structure 200.

[0076] The spring clamp structure 100 includes an intermediate connecting part 1 and two clamping and limiting parts 2. The intermediate connecting part 1 is connected to the two clamping and limiting parts 2 respectively, that is, one end of the intermediate connecting part 1 is connected to one of the clamping and limiting parts 2, and the other end of the intermediate connecting part 1 is connected to the other clamping and limiting part 2, thereby forming an overall spring clamp structure 100.

[0077] The two clamping limit parts 2 are used to respectively cooperate with the ball head structure 300 in a limited position, that is, the two clamping limit parts 2 can be distributed on both sides of the ball head structure 300 or other specific positions to cooperate with the ball head structure 300 in a limited position, limit the ball head structure 300 from moving in the radial or axial direction, thereby preventing the ball head structure 300 from escaping from the ball socket structure 200, and at the same time ensure that the ball head structure 300 can rotate freely within the limited range, achieving flexible rotation. Figure 8 and Figure 29 As shown, the two clamping limit portions 2 are distributed on opposite sides of the ball head structure 300 in the radial direction ( Figure 2 The left and right sides shown in the figure) are used to limit the ball head structure 300 between the two clamping limit parts 2, thereby limiting the axial movement of the ball head structure 300 from escaping from the ball socket structure 200, and also limiting the radial movement range.

[0078] Furthermore, at least part of the two snap-fit ​​limit portions 2 are constructed as inclined extension sections, which extend obliquely in the direction away from the middle connecting portion 1 along the direction in which the ball head structure 300 is inserted into the ball socket structure 200 to form a support angle between the two inclined extension sections.

[0079] refer to Figure 6-Figure 9 As shown, at least part of the left and right clamping limit parts 2 are constructed as inclined extension sections, and the direction of the inclined extension sections away from the middle connecting part 1 is Figure 6As shown in the left and right directions of the middle connecting part 1, the direction in which the left inclined extension section is away from the middle connecting part 1 is the left direction, and the direction in which the right inclined extension section is away from the middle connecting part 1 is the right direction. The direction in which the ball head structure 300 is inserted into the ball socket structure 200 is the up and down direction, so that the two inclined extension sections extend downwardly in the direction away from the middle connecting part 1 to form a support angle between the two inclined extension sections.

[0080] The support angle formed by the two inclined extension sections can effectively improve the load-bearing capacity and durability of the retaining spring structure 100. Therefore, after the ball head structure 300 is inserted into the ball socket structure 200, the retaining spring structure 100 can effectively disperse the force on the ball head structure 300 and support the ball head structure 300, and is not easy to fall out of the ball socket structure 200, thereby improving the installation stability and reliability of the retaining spring structure 100.

[0081] According to the retaining spring structure 100 of an embodiment of the present invention, by constructing at least parts of the two clamping limit parts 2 as inclined extension sections, the inclined extension sections are inclinedly extended in the direction away from the middle connecting part 1 along the direction in which the ball head structure 300 is inserted into the ball socket structure 200 to form a support angle between the two inclined extension sections, thereby effectively improving the load-bearing capacity and durability of the retaining spring structure 100. After the ball head structure 300 is inserted into the ball socket structure 200, the retaining spring structure 100 can effectively disperse the force of the ball head structure 300 and bear the ball head structure 300, so that the ball head structure 300 is not easy to fall out of the ball socket structure 200, thereby improving the installation stability and reliability of the ball head structure 300.

[0082] In some embodiments, each of the clamping and limiting portions 2 includes a clamping and limiting section 24 . The clamping and limiting sections 24 of the two clamping and limiting portions 2 are spaced apart and relatively distributed, and respectively cooperate with two sides of the ball head structure 300 .

[0083] Specifically, if Figure 7-Figure 9 As shown, each snap-fitting limit portion 2 includes a snap-fitting limit section 24. The snap-fitting limit sections 24 of the two snap-fitting limit portions 2 are spaced apart by a certain distance and are distributed relative to each other. In this way, the two snap-fitting limit sections 24 can respectively contact the ball head structure 300 from both sides of the ball head structure 300 to form a symmetrical limiting effect, thereby effectively limiting the range of motion of the ball head structure 300 while maintaining a certain degree of flexibility, thereby preventing the ball head structure 300 from excessive movement or escaping from the control of the snap-fitting limit portion 2 and escaping from the ball socket structure 200, thereby achieving effective snap-fitting limit and positioning of the ball head structure 300.

[0084] Among them, the relatively distributed clamping limit sections 24 can also evenly apply a limit force to the ball head structure 300 to prevent the ball head structure 300 from excessively deflecting or shaking during movement, thereby ensuring the movement stability and movement accuracy of the ball head structure 300.

[0085] In some embodiments, the clamping and limiting portion 2 further includes a first supporting segment 22 . The first supporting segment 22 is located between the middle connecting portion 1 and the clamping and limiting segment 24 , and the first supporting segment 22 is suitable for supporting the ball and socket structure 200 .

[0086] Specifically, if Figure 6 and Figure 9 As shown, the clamping limit portion 2 also includes a first support segment 22, which is located between the middle connecting portion 1 and the clamping limit segment 24. After the retaining spring structure 100 is installed on the ball socket structure 200, the first support segment 22 is supported on the ball socket structure 200. The function of the first support segment 22 is to provide support to ensure that the clamping limit portion 2 of the retaining spring structure 100 can be stably installed on the ball socket structure 200, thereby ensuring that the clamping limit segment 24 can stably cooperate with the ball head structure 300 to achieve the limitation of the ball head structure 300.

[0087] Therefore, through the supporting effect of the first supporting section 22, stable support can be provided for the clamping limit part 2, ensuring that it is more firmly matched with the ball socket structure 200, and making the clamping limit part 2 less likely to shift or shake, thereby improving the stability and load-bearing capacity of the entire spring structure 100, and ensuring that the clamping limit section 24 can accurately and stably cooperate with the ball head structure 300, thereby realizing a precise limiting effect, making it difficult for the ball head structure 300 to fall out of the ball socket.

[0088] In some embodiments, the inclined extension section includes a first inclined section 21 and a second inclined section 23 . The first inclined section 21 is connected between the intermediate connecting portion 1 and the first supporting section 22 , and the second inclined section 23 is connected between the first supporting section 22 and the clamping limit section 24 .

[0089] Specifically, if Figure 6 and Figure 7As shown, the inclined extension section includes a first inclined section 21 and a second inclined section 23. The first inclined section 21 extends downwardly and the second inclined section 23 extends backward. One end of the first inclined section 21 is connected to the intermediate connecting portion 1, and the other end of the first inclined section 21 is connected to one end of the first supporting section 22, so that the first inclined section 21 is connected between the intermediate connecting portion 1 and the first supporting section 22, one end of the second inclined section 23 is connected to the other end of the first supporting section 22, and the other end of the second inclined section 23 is connected to the clamping limit section 24, so that the second inclined section 23 is connected between the first supporting section 22 and the clamping limit section 24. As a result, the first inclined section 2 1. The second inclined section 23, the first supporting section 22 and the clamping limit section 24 are connected as an integral structure, which improves the structural strength of the retaining spring structure 100. Particularly, due to the inclined extension of the first inclined section 21 and the second inclined section 23, the load-bearing capacity and durability of the retaining spring structure 100 can be further improved, thereby further improving the installation stability and accuracy of the ball head structure 300, that is, the retaining spring structure 100 can be more stably and reliably clamped to fix the ball head structure 300, preventing the retaining spring structure 100 from severe deformation and inability to support the ball head structure 300, thereby increasing the effect of preventing the ball head structure 300 from escaping from the ball socket structure 200.

[0090] In some embodiments, the snap-fit ​​limit portion 2 further includes a second support segment 26 , which is located at one end of the snap-fit ​​limit portion 24 away from the intermediate connection portion 1 and is spaced apart from the first support segment 22 . The second support segment 26 is suitable for supporting the ball and socket structure 200 .

[0091] Specifically, if Figure 6 and Figure 7 As shown, the clamping limit portion 2 further includes a second support segment 26. The second support segment 26 is located at one end of the clamping limit segment 24 away from the middle connecting portion 1. Figure 6 As shown in the front-to-back direction, the second support section 26 is located at the rear end of the clamping limit section 24. The function of the second support section 26 is to provide support to ensure that the clamping limit portion 2 of the retaining spring structure 100 can be stably installed on the ball socket structure 200, thereby ensuring that the clamping limit section 24 can stably cooperate with the ball head structure 300 to achieve the limitation of the ball head structure 300.

[0092] The second support segment 26 is spaced apart from the first support segment 22, so that the first support segment 22 and the second support segment 26 can provide support at different locations, such as Figure 6As shown in the front-to-back direction, the first support section 22 can provide support in front of the ball socket structure 200, and the second support section 26 can provide support in the rear of the ball socket structure 200, thereby improving the overall support effect of the retaining spring structure 100, improving the structural strength and bearing capacity of the retaining spring structure 100, and further ensuring that the clamping limit portion 2 of the retaining spring structure 100 can be more stably installed on the ball socket structure 200, so that the retaining spring structure 100 can provide stable support for the ball head structure 300 at both the front and rear positions, ensuring that the clamping limit section 24 can cooperate with the ball head structure 300 more stably.

[0093] In some embodiments, the inclined extension section further includes a third inclined section 25 , and the third inclined section 25 is connected between the clamping limit section 24 and the second supporting section 26 .

[0094] Specifically, if Figure 6 and Figure 7 As shown, the inclined extension section also includes a third inclined section 25, one end of the third inclined section 25 is connected to the second supporting section 26, and the other end of the third inclined section 25 is connected to the clamping limit section 24, so that the third inclined section 25 is connected between the clamping limit section 24 and the second supporting section 26. As a result, the third inclined section 25, the second supporting section 26 and the clamping limit section 24 are connected as an integral structure, which improves the structural strength of the retaining spring structure 100. Due to the inclined extension of the third inclined section 25, the bearing capacity and durability of the retaining spring structure 100 can be further improved, thereby further improving the installation stability and accuracy of the ball head structure 300, that is, the retaining spring structure 100 can more stably and reliably clamp and fix the ball head structure 300, preventing the retaining spring structure 100 from severe deformation and inability to stably support the ball head structure 300, thereby further increasing the effect of preventing the ball head structure 300 from escaping from the ball socket structure 200.

[0095] In some embodiments, the distance between the first support sections 22 of the two snap-fit ​​limit parts 2 is L1, the distance between the snap-fit ​​limit sections 24 of the two snap-fit ​​limit parts 2 is L2, and the distance between the second support sections 26 of the two snap-fit ​​limit parts 2 is L3, and satisfies: L2<L1<L3.

[0096] Specifically, if Figure 6 As shown, the distance between the two first support segments 22 is L1, the distance between the two clamping limit segments 24 is L2, and the distance between the two second support segments 26 is L3, wherein L2<L1<L3, that is, the distance between the two clamping limit segments 24 is the smallest, and the distance between the two second support segments 26 is the largest.

[0097] As a result, the entire spring retaining structure 100 presents a shape that changes from wide to narrow and then to wide. The larger distance between the two second support segments 26 makes it easier for the spring retaining structure 100 to be clamped into the ball socket structure 200. The smaller distance between the two clamping limit segments 24 allows the two clamping limit segments 24 to stably clamp the ball head structure 300 to achieve effective positioning of the ball head structure 300, and the slightly larger distance between the two first support segments 22 prevents the spring retaining structure 100 from falling off easily after being installed on the ball socket structure 200.

[0098] In some embodiments, the two clamping limit portions 2 are symmetrically distributed at both ends of the middle connecting portion 1 .

[0099] Specifically, if Figure 6-Figure 9 As shown, the two clamping limit parts 2 are symmetrically distributed at the left and right ends of the middle connecting part 1, that is, the two clamping limit parts 2 have the same structure. Therefore, the two symmetrically distributed clamping limit parts 2 can improve the overall stability of the retaining spring structure 100, so that when the two clamping limit parts 2 are respectively limited with the ball head structure 300, it can ensure that the two clamping limit parts 2 and the ball head structure 300 are uniformly stressed, thereby improving the limiting stability of the ball head structure 300, and the two clamping limit parts 2 on both sides can share the weight and external force of the ball head structure 300, thereby preventing the retaining spring structure 100 from loosening or falling off, and further effectively preventing the ball head structure 300 from falling out of the ball socket structure 200.

[0100] In other embodiments, Figure 8 As shown, the support angle is a and satisfies: 90°<a<180°.

[0101] That is to say, the support angle a can be set to 95°, 100°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 178° or other angles between 90° and 180°.

[0102] Among them, if the support angle a is set too small, it is easy to cause the retaining spring structure 100 to fall off and cannot be stably installed on the ball and socket structure 200. If the support angle a is set too large, it is not conducive to the installation and removal of the retaining spring structure 100.

[0103] Therefore, by setting the support angle a to an angle between 90° and 180°, the structural strength and load-bearing capacity of the retaining spring structure 100 can be guaranteed, and it can withstand the weight of the ball head structure 300 without serious deformation. It can also ensure that the retaining spring structure 100 is stably installed on the ball socket structure 200 and is not easy to fall off from the ball socket structure 200, thereby improving the limiting reliability of the ball head structure 300, and also facilitating the retaining spring structure 100 to be installed on and removed from the ball socket structure 200, thereby improving the convenience of disassembly.

[0104] The present invention also provides a ball and socket assembly 1000 .

[0105] According to an embodiment of the present invention, the ball and socket assembly 1000 includes a ball and socket structure 200, a ball head structure 300 and a retaining spring structure 100 of any one of the above embodiments. The ball head structure 300 is inserted into the ball and socket structure 200, the retaining spring structure 100 is installed on the ball and socket structure 200, and the clamping limit portion 2 is used to limit the ball head structure 300 along the insertion direction of the ball head structure 300 and the ball and socket structure 200.

[0106] Specifically, if Figure 1 and Figure 2 As shown, the ball and socket assembly 1000 includes a ball and socket structure 200, a ball head structure 300 and a retaining spring structure 100. The ball head structure 300 can be inserted into the ball and socket structure 200 from top to bottom along the up and down directions. The retaining spring structure 100 is installed in the ball and socket structure 200. The snap-fit ​​limiting portion 2 is used to limit the ball head structure 300 along the insertion direction of the ball head structure 300 and the ball and socket structure 200, that is, the snap-fit ​​limiting portion 2 is used to axially limit the ball head structure 300 to prevent the ball head structure 300 from moving upward or downward to fall out of the ball and socket structure 200.

[0107] Among them, in the retaining spring structure 100, by constructing at least parts of the two clamping limit parts 2 as inclined extension sections, the inclined extension sections are inclinedly extended in the direction away from the middle connecting part 1 along the direction of the ball head structure 300 being inserted into the ball socket structure 200, so as to form a support angle between the two inclined extension sections, thereby effectively improving the load-bearing capacity and durability of the retaining spring structure 100. Therefore, after the ball head structure 300 is inserted into the ball socket structure 200, the retaining spring structure 100 can effectively disperse the force of the ball head structure 300 and bear the ball head structure 300, and it is not easy to fall out of the ball socket structure 200, thereby improving the installation stability and reliability of the ball head structure 300.

[0108] Therefore, through the setting of the retaining spring structure 100, the installation stability and reliability of the ball head structure 300 are greatly improved, and the ball head structure 300 is effectively prevented from being offset and detached from the ball socket structure 200, thereby improving the working stability and reliability of the ball socket assembly 1000. In addition, the retaining spring structure 100 is simple, easy to install, has a strong load-bearing capacity, and can reduce manufacturing costs.

[0109] In some embodiments, a ball socket hole 2021 and an inserting groove 203 are formed in the ball socket structure 200 , the inserting groove 203 is connected to the ball socket hole 2021 , and the ball head structure 300 is provided with a limiting groove 3011 .

[0110] Specifically, if Figures 15-18 As shown, a ball socket hole 2021 and a plug-in slot 203 are formed in the ball socket structure 200. The ball socket hole 2021 is used to accommodate the ball head structure 300, and the plug-in slot 203 is used to install the retaining spring structure 100. The ball socket hole 2021 can be set as a circular hole, an elliptical hole, a spherical hole or a hole of other shapes, and can be flexibly set according to actual conditions and needs. Among them, the plug-in slot 203 is connected to the ball socket hole 2021, so that it is convenient for the retaining spring structure 100 to be installed in the plug-in slot 203 to further limit the ball socket structure 200. Figure 14 As shown, the ball head structure 300 is provided with a limiting groove 3011, which is concave inward along the circumference of the ball head structure 300. The retaining spring structure 100 can extend into the limiting groove 3011 to achieve the clamping and limiting of the ball head structure 300, limiting the axial displacement of the ball head structure 300 and escaping from the ball socket structure 200.

[0111] Furthermore, the ball head structure 300 is inserted into the ball socket hole 2021 , and the retaining spring structure 100 is inserted into the insertion groove 203 and at least partially extends into the limiting groove 3011 to cooperate with the ball head structure 300 in a limiting manner.

[0112] That is to say, the ball head structure 300 can be inserted into the ball socket hole 2021 from top to bottom to achieve the coordinated installation of the ball head structure 300 and the ball socket structure 200, and the retaining spring structure 100 can be extended from the outside to the inside into the plug-in groove 203 to achieve the plug-in connection between the retaining spring structure 100 and the plug-in groove 203. At the same time, at least a part of the retaining spring structure 100, namely the clamping limit section 24, is limited and matched with the ball head structure 300 in the limit groove 3011, thereby achieving the clamping limit of the ball head structure 300, limiting the axial displacement of the ball head structure 300 and escaping from the ball socket structure 200.

[0113] In addition, the retaining spring structure 100 and the ball head structure 300 of the present invention are limited and cooperated, so it is not easy to generate abnormal noise, which reduces the noise generation.

[0114] During the actual installation process, Figure 14 、 Figure 29 and Figure 30 As shown, the ball head structure 300 is inserted into the ball socket hole 2021 from top to bottom. During the downward insertion of the ball head structure 300, the two snap-fit ​​limit sections 24 will open in directions away from each other under the action of the ball head structure 300, that is, open toward the outside, until the distance between the two snap-fit ​​limit sections 24 can allow the maximum size of the ball head structure 300 to be snapped into between the two snap-fit ​​limit sections 24. After that, the ball head structure 300 will continue to move downward. At the same time, the two snap-fit ​​limit sections 24 will reset in a direction close to each other until the two snap-fit ​​limit sections 24 extend into the limit groove 3011 to cooperate with the ball head structure 300 to limit the ball head structure 300, thereby realizing the limitation of the ball head structure 300.

[0115] In some embodiments, the ball socket structure 200 includes a first ball socket shell 201 and a second ball socket shell 202 , an insertion groove 203 is formed between the first ball socket shell 201 and the second ball socket shell 202 , and a ball socket hole 2021 is formed in the second ball socket shell 202 .

[0116] Specifically, if Figure 2 、 Figures 14-18 As shown, the ball socket structure 200 includes a first ball socket shell 201 and a second ball socket shell 202. Figure 2 As shown in the upper and lower directions, the first ball socket shell 201 is located on the upper side and the second ball socket shell 202 is located on the lower side. A certain distance is separated between the first ball socket shell 201 and the second ball socket shell 202 to form a plug-in groove 203, and a cavity is provided in the second ball socket shell 202 to form a ball socket hole 2021.

[0117] Furthermore, the ball head structure 300 includes a rod body 302 and a ball head 301. The rod body 302 is inserted into the first ball socket shell 201, and the ball head 301 extends into the ball socket hole 2021. A limiting groove 3011 is formed at the connection between the rod body 302 and the ball head 301.

[0118] Specifically, if Figure 14 As shown, the ball head structure 300 includes a rod body 302 and a ball head 301. The connection between the rod body 302 and the ball head 301 is circumferentially concave inward to form an annular retaining groove 3011. The size of the retaining groove 3011 matches the size of the engaging retaining section 24 of the retaining spring structure 100, facilitating the retaining spring structure 100 to extend into the retaining groove 3011 and retain the ball head structure 300. The first ball socket shell 201 is used to accommodate the rod body 302, and the second ball socket shell 202 is used to accommodate the ball head 301. The shape and size of the ball socket hole 2021 in the second ball socket shell 202 match those of the ball head 301, so that the ball head 301 can be smoothly inserted and accommodated in the ball socket hole 2021 while ensuring a certain degree of flexibility.

[0119] When the ball head structure 300 is actually installed, the ball head portion 301 first extends downward into the ball socket hole 2021, and then the rod body portion 302 is downwardly passed through the first ball socket shell 201. At the same time, the retaining spring structure 100 will deform so that its retaining limit section 24 extends into the limit groove 3011 to axially limit the ball head portion 301.

[0120] Among them, such as Figure 10-13 As shown, after the retaining spring structure 100 is installed in the plug-in slot 203 , no cut edge of the retaining spring structure 100 is exposed, thus improving the salt spray performance of the retaining spring structure 100 and thereby increasing the service life of the retaining spring structure 100 .

[0121] In some embodiments, the inner wall surface of the first ball socket shell 201 and / or the second ball socket shell 202 is constructed as a limiting contour surface 204, the shape of the limiting contour surface 204 is the same as the shape of the snap-fit ​​limiting portion 2, and the limiting contour surface 204 is used to cooperate with the snap-fit ​​limiting portion 2 in the upper limit direction of the plug-in spring structure 100.

[0122] That is to say, the inner wall surface of the first ball socket shell 201 can be constructed as a limiting contour surface 204, or the inner wall surface of the second ball socket shell 202 can be constructed as a limiting contour surface 204, and the shape of the limiting contour surface 204 is the same as the shape of the clamping limiting part 2. In this way, after the retaining spring structure 100 is inserted into the insertion groove 203, the surface of the clamping limiting part 2 of the retaining spring structure 100 is tightly fitted with the limiting contour surface 204, thereby realizing the installation of the retaining spring structure 100 on the ball socket structure 200, and the limiting contour surface 204 and the clamping limiting part 2 are limited in the insertion direction of the retaining spring structure 100, effectively preventing the retaining spring structure 100 from falling off from the ball socket structure 200.

[0123] Specifically, if Figures 19-22 As shown, the inner wall surface of the second ball socket shell 202 is constructed as a limiting contour surface 204. The shape of the limiting contour surface 204 is the same as the shape of the clamping limiting portion 2. The plugging direction of the clamping spring structure 100 is Figure 2 In the front-to-back direction shown in , the spring structure 100 is inserted into the plug-in slot 203 from front to back. After the spring structure 100 is plugged into the plug-in slot 203, the surface of the clamping limit portion 2 of the spring structure 100 is tightly fitted with the limiting contour surface 204. Since the size of the limiting contour surface 204 also increases, decreases, and then increases from front to back, the limiting contour surface 204 can restrict each other with the clamping limit portion 2, restricting the movement of the spring structure 100 in the front-to-back direction, ensuring that the spring structure 100 can be stably maintained in the plug-in slot 203 after insertion, so that the spring structure 100 will not fall off or move at will.

[0124] In some embodiments, one of the first ball socket shell 201 and the second ball socket shell 202 is provided with a disassembly groove 205, which is connected to the insertion groove 203. The disassembly groove 205 is used for the disassembly tool 500 to extend into, and the disassembly tool 500 is used to disassemble the retaining spring structure 100 to allow the clamping limit portion 2 to detach from the limit contour surface 204.

[0125] That is to say, a disassembly groove 205 can be set on the first ball socket shell 201, or a disassembly groove 205 can be set on the second ball socket shell 202, and the disassembly groove 205 is connected to the plug-in groove 203, and the disassembly tool 500 can be extended into the disassembly groove 205 and contact the intermediate connecting part 1 to disassemble the spring structure 100, so that the clamping limit part 2 is separated from the limit contour surface 204, that is, the distance between the two clamping limit sections 24 increases until the ball head 301 can be disengaged from between the two clamping limit parts 2, thereby realizing the disassembly of the ball head structure 300. Afterwards, the spring structure 100 can be reset under the action of its own elastic force, that is, the clamping limit part 2 is fit and connected to the limit contour surface 204 again.

[0126] Specifically, if Figures 29-32 As shown, a disassembly groove 205 is provided on the second ball socket shell 202, and the disassembly groove 205 extends along the height direction of the second ball socket shell 202 and is connected with the plug-in groove 203. The disassembly tool 500 can be extended into the disassembly groove 205 and contact the intermediate connecting part 1, and then a certain force is applied. Under the action of the second inclined section 23 and the limiting contour surface 204, the clamping limiting part 2 is separated from the limiting contour surface 204, and the two clamping limiting sections 24 are opened in directions away from each other, that is, they are opened toward the outside, so that the distance between the two clamping limiting sections 24 increases until the ball head 301 can be disengaged from between the two clamping limiting sections 24, thereby realizing the disassembly of the ball head structure 300.

[0127] In some embodiments, one of the first ball socket shell 201 and the second ball socket shell 202 is also formed with two disassembly inclined surfaces 206, and the two disassembly inclined surfaces 206 respectively correspond to the two snap-in limit parts 2 one by one, and the two snap-in limit parts 2 are suitable for deforming along the corresponding disassembly inclined surfaces 206 in a direction away from each other under the action of the disassembly tool 500.

[0128] Specifically, if Figure 25-27 As shown, two disassembly inclined surfaces 206 are formed on the second ball socket shell 202, and the two disassembly inclined surfaces 206 respectively cooperate with the two clamping limit parts 2 one by one, that is, each disassembly inclined surface 206 has a clamping limit part 2 to cooperate with it, and the two disassembly inclined surfaces 206 can provide guidance and disperse force for the two clamping limit parts 2 during the disassembly process.

[0129] When the disassembly tool 500 is actually used to disassemble the ball head structure 300, the disassembly tool 500 can be extended into the disassembly groove 205, and then a certain force F is applied. Then, the two clamping limit parts 2 will be deformed along the corresponding disassembly inclined surfaces 206 in the direction away from each other under the action of the force applied by the disassembly tool 500, so that the distance between the two clamping limit parts 2 increases until the ball head part 301 can be disengaged from between the two clamping limit parts 2, thereby realizing the disassembly of the ball head structure 300. After the ball head structure 300 is disassembled, the two clamping limit parts 2 can also be reset along the two disassembly inclined surfaces 206 in the direction close to each other.

[0130] Therefore, by setting the disassembly inclined surface 206, a smooth disassembly path is provided for the two clamping limit parts 2, which can guide the two clamping limit parts 2 to deform along their surfaces, making the disassembly process simpler and more efficient, and avoiding damage to the retaining spring structure 100 due to direct force during the disassembly process, thereby improving the service life of the retaining spring structure 100.

[0131] In some embodiments, the ball and socket assembly 1000 further includes a buffer 400 , which is mounted on the first socket shell 201 . A support protrusion 303 is provided outside the rod body 302 , and the buffer 400 is supported between the support protrusion 303 and the first socket shell 201 .

[0132] Specifically, if Figure 1 As shown, the ball and socket assembly 1000 further includes a buffer member 400, which is installed in the first ball and socket shell 201. Figure 14 As shown, a supporting protrusion 303 is provided on the outside of the rod body 302, and the supporting protrusion 303 is located at the upper part of the limiting groove 3011. In this way, when the ball head structure 300 is installed in the ball socket structure 200, the buffer component 400 is supported between the supporting protrusion 303 and the first ball socket shell 201, thereby ensuring the stable installation of the buffer component 400.

[0133] Furthermore, when the ball head structure 300 rotates rapidly, the rod body 302 of the ball head structure 300 will collide with the first ball socket shell 201. The setting of the buffer 400 can make the rod body 302 contact the buffer 400 to provide buffering and avoid the generation of abnormal impact noise.

[0134] In actual design, the buffer member 400 can be made of elastic material.

[0135] In some embodiments, the buffer member 400 defines a through hole 401 , and the rod portion 302 is disposed through the through hole 401 .

[0136] Specifically, if Figure 33-Figure 35As shown, the buffer component 400 is provided with a through hole 401, which is connected to the ball socket hole 2021. In this way, when the ball head structure 300 is installed, the ball head portion 301 can be extended into the ball socket hole 2021 through the through hole 401, and the rod body portion 302 is passed through the through hole 401, and the rod body portion 302 can rotate within a certain range in the through hole 401.

[0137] In actual design, the through holes 401 can be constructed as circular holes, elliptical holes, etc.

[0138] In other embodiments, the first ball socket shell 201 is provided with a mounting groove 2011 , and the buffer member 400 is disposed in the mounting groove 2011 and is positionally engaged with the first ball socket shell 201 .

[0139] Specifically, if Figure 15 As shown, the first ball socket shell 201 is concave, that is, concave downward by a certain distance to form a mounting groove 2011. The shape and size of the mounting groove 2011 match the shape and size of the buffer component 400, so that the buffer component 400 can be installed in the mounting groove 2011 and limited by the first ball socket shell 201 to ensure stable installation of the buffer component 400.

[0140] In actual design, Figure 34 As shown, a limit block 402 may be provided on the buffer member 400, as shown in FIG. Figure 4 As shown, a limiting hole 207 is provided on the first ball socket shell 201, and the limiting block 402 matches the limiting hole 207, so that the limiting block 402 can extend into the limiting hole 207 to achieve limiting cooperation between the buffer component 400 and the first ball socket shell 201, preventing the buffer component 400 from shaking or deflecting.

[0141] In addition, the buffer component 400 can also be installed on the first ball socket shell 201 through other fixed connection methods, and glue can also be injected on the first ball socket shell 201 so that the buffer component 400 can be adhered to the first ball socket shell 201, thereby better realizing the fixed connection between the buffer component 400 and the first ball socket shell 201.

[0142] The present invention also provides a strut assembly including the ball and socket assembly 1000 according to any one of the above embodiments.

[0143] According to the strut assembly of the embodiment of the present invention, by providing the above-mentioned ball and socket assembly 1000, it can be ensured that the strut assembly can maintain a stable connection under any working conditions, thereby improving the safety and reliability of the strut assembly and extending the service life of the strut assembly.

[0144] The support rod assembly of this embodiment can be a hood support rod, a trunk support rod, a tailgate support rod, etc.

[0145] The present invention also provides a vehicle comprising the strut assembly of the above embodiment.

[0146] According to the vehicle of the embodiment of the present invention, the overall stability and safety of the vehicle can be enhanced by the above-mentioned strut assembly, thereby ensuring that the vehicle can travel safely and ensuring the safety of passengers.
