[0041] To make the technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings
[0042] The first aspect of the present application provides a ball seat, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the ball socket includes a socket body 1, a buffer member 2, and a limiting member 3. The socket body 1 has a ball socket cavity 101, a first opening 102, a second opening 103, and a side through hole 104. The first opening 102, the second opening 103, and the side through hole 104 are respectively in communication with the ball socket cavity 101. Among them,
[0043] The first opening 102 and the second opening 103 are located at both ends of the ball socket cavity 101 along the first direction X, and the side through hole 104 is located between the first opening 102 and the second opening 103 along the first direction X.
[0044] A part of the limiting member 3 covers the first opening 102.
[0045] Another part of the limiting member 3 extends into the ball socket cavity 101 through the side through hole 104.
[0046] The buffer member 2 is located between the first opening 102 and the side through hole 104.
[0047] It can be understood that the first opening 102 of the ball socket can allow the buffer member 2 to pass through and be placed into the ball socket cavity 101. The limiting member 3 covers the first opening 102, which can limit the buffer member 2 and reduce the situation where the buffer member 2 escapes through the first opening 102. The second opening 103 of the ball socket can allow the ball head 4 to pass through and be placed into the ball socket cavity 101. The limiting member 3 extends into the ball socket cavity 101 through the side through hole 104, which is beneficial to limiting the ball head 4 located in the ball socket cavity 101. In this way, at least a part of the ball head 4 is kept in contact with the buffer member 2. The buffer member 2 can be used to contact the ball head 4 and buffer the ball head 4 to reduce the noise generated by the friction between the ball head 4 and the ball socket.
[0048] In the embodiment of the present application, the socket body 1 can be formed by steel cutting or aluminum precision casting. The material of the ball head 4 is generally similar to that of the socket body 1. When the two collide, obvious vibrations can occur, resulting in noise from the spherical hinge. The present application uses the buffer part to buffer the ball head 4 to reduce the noise generated by it.
[0049] In the embodiment of the present application, the buffer member 2 is used to buffer the ball head 4. It can form a buffer for the ball head 4 depending on its own material properties or its structural properties.
[0050] In the embodiment of the present application, the first opening 102 and the second opening 103 are located at both ends of the ball socket cavity 101 along the first direction X. This is beneficial for the buffer member 2 to pass through the first opening 102 and be placed into the ball socket cavity 101, and is also beneficial for the ball head 4 to pass through the second opening 103 and be placed into the ball socket cavity 101, which can reduce the interference between the buffer member 2 and the ball head 4 during assembly.
[0051] In the embodiment of the present application, the side through-hole 104 is located between the first opening 102 and the second opening 103 along the first direction X, which is beneficial for the buffer member 2 to be arranged between the first opening 102 and the side through-hole 104, so that a space for accommodating the ball head 4 is formed between the buffer member 2 and the part of the limiting member 3 extending into the ball socket cavity 101 through the side through-hole 104, and it is beneficial for the limiting member 3 to limit the ball head 4.
[0052] In the embodiment of the present application, a part of the limiting member 3 covers the first opening 102, which is beneficial for interfering with the buffer member 2. When the buffer member 2 is impacted by the ball head 4, the buffer member 2 can be limited within the ball socket cavity 101, reducing the situation of the ball seat failure of the present application. Among them, the limiting member 3 can cover a part of the first opening 102 or completely cover the first opening 102.
[0053] In the embodiment of the present application, another part of the limiting member 3 extends into the ball socket cavity 101 through the side through-hole 104, which is beneficial for a connection force to be generated between the limiting member 3 and the seat body 1 through the connection, and the connection force is beneficial for the limiting member 3 to limit the ball head 4 within the ball socket cavity 101. Among them, the limiting member 3 and the seat body 1 can be directly connected by bonding, clamping or welding, etc., or can be connected through an intermediate member such as a bolt.
[0054] In the embodiment of the present application, a part and another part of the limiting member 3 do not mean that the limiting member is composed of two parts, but mean that there are at least two different parts of the limiting member 3, so that the limiting member 3 can cover the first opening 102 while extending into the ball socket cavity 101.
[0055] In the embodiment of the present application, when the ball head 4 moves in a direction perpendicular to the first direction X, it will be interfered by the seat body 1 and cannot escape from the ball socket cavity 101. A part of the buffer member 2 is located between the first opening 102 and the side through-hole 104, which can make the ball head 4 be interfered by the buffer member 2 and the limiting member 3 when moving along the first direction X, and cannot escape from the ball socket cavity 101 through the first opening 102 or the second opening 103.
[0056] In the embodiment of the present application, the limiting member 3 can be detachably connected to the seat body 1 by clamping, bolt connection, etc.
[0057] In some embodiments of the present application, as Figure 4 shown, the limiting member 3 includes a covering part 31 and a connecting part 32. The covering part 31 is connected to the connecting part 32. The covering part 31 covers at least a part of the first opening 102, and the connecting part 32 extends into the ball socket cavity 101 through the side through-hole 104.
[0058] It can be understood that the covering portion 31 and the connecting portion 32 facilitate the limiting member 3 to simultaneously cover the first opening 102 and extend into the ball socket cavity 101, thereby realizing the limiting effect on the buffer member 2 and the ball head 4.
[0059] In the embodiment of the present application, the connecting portion 32 and the seat body 1 can be directly connected by means of bonding, clamping or welding, etc., or can be connected through an intermediate member such as a bolt. In this way, the connecting force generated by the connection can interfere with the part of the ball head 4 located in the ball socket cavity 101.
[0060] In the embodiment of the present application, a groove can be provided on the outer side of the seat body 1 near the first opening 102 for the connecting portion 32 to be placed in. In this way, it is beneficial to form a relatively smooth structure on the outer surface of the seat body 1, and reduce the situation that the connecting portion 32 is impacted on the outer surface of the seat body 1 and disengages from the side through hole 104.
[0061] In the embodiment of the present application, the covering portion 31, the buffer member 2, and the end of the connecting portion 32 away from the covering portion 31 are arranged in sequence along the first direction X. In this way, it is beneficial for the covering portion 31 and the connecting portion 32 to interfere with the buffer member 2 in the first direction X.
[0062] In the embodiment of the present application, the covering portion 31 and the connecting portion 32 can be made by an integral forming process such as cutting a sheet metal part. In this way, it is beneficial for the limiting member 3 to have sufficient structural strength to resist the impact from the ball head 4 or other components. In some embodiments of the present application, such as Figure 4 shown, the number of the connecting portions 32 is at least two, the number of the side through holes 104 corresponds to the number of the connecting portions 32, both ends of the covering portion 31 are correspondingly connected to two of the at least two connecting portions 32, the two side through holes 104 are respectively located on opposite sides of the ball socket cavity 101, and the two connecting portions 32 correspondingly extend into the ball socket cavity 101 through the two side through holes 104.
[0063] It can be understood that the two connecting portions 32 extending into the corresponding side through holes 104 are beneficial to generate connecting forces with different directions between the two connecting portions 32 and the seat body 1. The connecting forces with different directions can improve the connection performance between the limiting member 3 and the seat body 1 to resist impacts from different directions, and further reduce the situation that the connecting portion 32 is impacted and disengages from the side through hole 104.
[0064] In the embodiment of the present application, the connecting portion 32 and the side wall of the side through hole 104 can be connected by means of clamping, bonding, etc. to improve the connection performance between the two.
[0065] In the embodiment of the present application, the covering portion 31 is arc-shaped, and the two connecting portions 32 are respectively located at both ends of the covering portion 31 and extend along the radial direction of the covering portion 31.
[0066] In some embodiments of the present application, as Figure 4 shown, along the first direction X, the side through-hole 104 extends obliquely from one end far away from the ball socket cavity 101 to the end communicating with the ball socket cavity 101 towards the second opening 103.
[0067] It can be understood that the obliquely extending side through-hole 104 can form interference with the connecting portion 32 extending into it to provide a connecting force, which is beneficial to helping the covering portion 31 resist the impact along the first direction X. In this way, the limiting effect of the limiting member 3 on the buffer member 2 and the ball head 4 can be improved. Among them, the two obliquely extending side through-holes 104 can also make the two connecting portions 32 form an inverted V shape in the ball socket cavity 101. In this way, it can limit the ball head 4 located in the ball socket cavity 101 and reduce the situation of the ball head 4 coming out of the ball socket cavity 101.
[0068] In the embodiments of the present application, the inclination angle of the side through-hole 104 can be 30°, 45°, 60° or 75°, or other angles between 0 and 90°. Among them, the inclination angle of the side through-hole 104 can be the included angle formed between the axial direction of the side through-hole 104 and the first direction X.
[0069] In the embodiments of the present application, the outer surface of the seat body 1 is generally spherical, and the covering portion 31 can be arc-shaped. In this way, it is beneficial for the covering portion 31 to cover the outer surface of the seat body 1 without protruding from the seat body 1, so as to reduce the situation of the limiting member 3 being damaged by impact.
[0070] In some embodiments of the present application, as Figure 4 shown, the orthographic projection of the buffer member 2 on the projection plane, the orthographic projection of the covering portion 31 on the projection plane, and the orthographic projection of the connecting portion 32 on the projection plane at least partially overlap. The projection plane is a plane perpendicular to the first direction X.
[0071] It can be understood that such a setting can enable the covering portion 31 and the connecting portion 32 to form an interference and limiting effect on the buffer member 2 located in the ball socket cavity 101 in the first direction X, which is beneficial to reducing the situation of the buffer member 2 coming out of the ball socket cavity 101.
[0072] In the embodiments of the present application, when the ball head 4 is subjected to a pulling force or bending moment to pull out of the ball socket cavity 101, the upper surface of the connecting portion 32 can be in direct contact with the lower side surface of the ball head 4 to play an anti-pulling role.
[0073] In some embodiments of the present application, as Figure 7 shown, the buffer member 2 includes a buffer body 22 and an enclosing portion 23. The enclosing portion 23 is connected to one side of the buffer body 22 and extends along the circumferential direction of the buffer body 22. A buffer cavity 201 is formed between the buffer body 22 and the enclosing portion 23.
[0074] It can be understood that the buffer cavity 201 can allow the ball head 4 to extend therein, and the buffer body 22 and the surrounding portion 23 can remain in contact with the ball head 4 when the ball head 4 moves, so as to replace the contact between the ball head 4 and the wall surface of the ball socket cavity 101, thereby reducing the collision between the ball head 4 and the seat body 1 and reducing the generated noise.
[0075] In the embodiment of the present application, the buffer body 22 and the surrounding portion 23 can be manufactured by processes such as injection molding and are connected.
[0076] In some embodiments of the present application, such as Figure 5 、 Figure 6 and Figure 7 shown, the seat body 1 includes a first positioning structure 11, the buffer member 2 has a second positioning structure 21, the first positioning structure 11 is located in the ball socket cavity 101 and is connected in cooperation with the second positioning structure 21.
[0077] It can be understood that the cooperation between the first positioning structure 11 and the second positioning structure 21 can improve the stability of the buffer member 2 in the ball socket cavity 101 and reduce the situation where the buffer member 2 is displaced or rotated due to the impact of the ball head 4.
[0078] In the embodiment of the present application, the first positioning structure 11 and the second positioning structure 21 can be formed in cooperation by means of snap connection, bonding, etc.
[0079] In some embodiments of the present application, such as Figure 5 and Figure 6 shown, the first positioning structure 11 includes two first convex portions, both of the two first convex portions extend along the circumferential direction of the ball socket cavity 101 and form a first groove along the circumferential direction of the buffer member 2, the second positioning structure 21 includes a second convex portion 221 and a second groove 222, both ends of the second convex portion 221 along the circumferential direction of the buffer member 2 respectively have the second groove 222, the two first convex portions correspondingly extend into the first groove, and the second convex portion 221 extends into the second groove 222.
[0080] It can be understood that the first groove can allow the second convex portion 221 to extend therein, the second groove 222 can allow the first convex portion to extend therein, when the second convex portion 221 has a tendency to move along the first direction X, it will be interfered by the side wall of the second groove 222, thereby restricting or delaying the tendency of movement, so as to restrict the movement of the buffer member 2 relative to the ball socket cavity 101 along the first direction X. The two first convex portions and the second convex portion 221 are arranged in the rotational direction of the buffer member 2, and interference can be formed between them when the buffer member 2 has a tendency to rotate, so as to delay or restrict the rotation of the buffer member 2, thereby restricting the rotation of the buffer member 2 relative to the ball socket cavity 101.
[0081] In some embodiments of the present application, such as Figure 5And Figure 6 As shown in Figure 6 , the buffer member 2 includes a buffer body 22 and an enclosing portion 23. The number of the enclosing portions 23 is at least two. Two of the at least two enclosing portions 23 are respectively connected to the buffer body 22 and are located on opposite sides of the buffer body 22. The buffer body 22 is close to the first opening 102. The two enclosing portions 23 are separated from each other along a direction perpendicular to the second direction Y. Each enclosing portion 23 has a second positioning structure 21. The second direction Y is perpendicular to the first direction X.
[0082] It can be understood that when the second positioning structure 21 passes through the first opening 102, it generally receives an interference effect from the seat body 1. Therefore, setting the two enclosing portions 23 to be separated from each other along a direction perpendicular to the second direction Y is beneficial for the two enclosing portions 23 to undergo sufficient deformation when passing through the first opening 102, and further beneficial for the second positioning structure 21 to enter the ball socket cavity 101 and cooperate with the first positioning structure 11.
[0083] In the embodiment of the present application, the number of the enclosing portions 23 can be two, three, or four, or other numbers.
[0084] In the embodiment of the present application, the buffer body 22 and the enclosing portion 23 can be manufactured by an integral molding process such as injection molding.
[0085] In some embodiments of the present application, the first positioning structure 11 is located at the first opening 102. The second positioning structure 21 cooperates with the first positioning structure 11 to seal the first opening 102, and the buffer member 2 is bonded to the seat body 1.
[0086] It can be understood that the first positioning structure 11 is located at the first opening 102, and the second positioning structure 21 cooperates with the first positioning structure 11 to seal the first opening 102, which is beneficial for reducing the situation where impurities enter the ball socket cavity 101 through the first opening 102. In this way, it is beneficial for reducing the friction and wear between the ball head 4 and the ball socket cavity 101 or the buffer member 2 caused by the presence of impurities. The buffer member 2 is bonded to the seat body 1, which can improve the assembly efficiency of the two. At the same time, the bonding can also keep the buffer member 2 relatively stable on the seat body 1, and further beneficial for the limiting member 3 to be assembled on the seat body 1 and play a certain limiting role on the buffer member 2.
[0087] In the embodiment of the present application, the area of the second positioning structure 21 is the same as or larger than the area of the first opening 102, and forms an abutment with the side wall of the first opening 102 to achieve sealing.
[0088] In the embodiments of the present application, the second positioning structure 21 may be a portion that protrudes outward circumferentially on the buffer member 2, and the first positioning structure 11 is a groove formed by recessing outward circumferentially along the first opening 102 on the seat body 1. The two cooperate to achieve sealing, and at the same time, it can limit the movement of the buffer member 2 along the first direction X towards the ball socket cavity 101.
[0089] In the embodiments of the present application, the outer surface of the buffer member 2 may be first coated with an adhesive and pressed into the ball socket cavity 101 from the first opening 102, so as to form an adhesion with the seat body 1.
[0090] In some embodiments of the present application, the material of the buffer member 2 includes at least one of nylon, plastic, and metal.
[0091] It can be understood that the above materials are beneficial for the buffer member 2 to buffer the ball head 4, and reduce the noise generated by the impact on the ball head 4.
[0092] The second aspect of the present application can provide a spherical hinge. The spherical hinge includes a ball head 4 and a ball seat as described in the above embodiments. At least a part of the ball head 4 extends into the ball socket cavity 101 and is in contact with the buffer member 2.
[0093] It can be understood that the ball socket cavity 101 provides a space for the ball head 4 to move, which is beneficial for the ball head 4 to rotate relative to the ball seat. The ball head 4 is in contact with the buffer member 2, which is beneficial for reducing the collision between the ball head 4 and the ball seat, and further reducing the generated noise.
[0094] In the embodiments of the present application, the diameter of the ball head 4 is consistent with the diameter of the ball socket cavity 101, and the ball head 4 abuts against the buffer member 2 in the ball socket cavity 101.
[0095] In the embodiments of the present application, the size of the second opening 103 is similar to the size of the ball head 4, so that the ball head 4 can pass through and enter the ball socket cavity 101. Exemplarily, the second opening 103 is circular, the ball head 4 is spherical, and the size of the second opening 103 is the same as the size of the circle of the ball head 4 passing through the center of the sphere.
[0096] In the embodiments of the present application, the ball socket cavity 101 can provide a movable space for the ball head 4, for the ball head 4 to perform activities such as moving and rotating.
[0097] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
[0098] Other embodiments of the present application will be readily apparent to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common general knowledge or conventional technical means in the technical field not disclosed in the present application.
