[0049] See also Figure 1 In one embodiment of the present invention, the upper support 100 of the automobile shock absorber with integrated bearing includes a mounting bracket 1, a housing 2, a rolling device 3 and an end cover 4; the mounting bracket 1 is provided with a first through hole 11 at the center of one end surface in the first direction for the shock absorber piston rod to pass through, the mounting bracket 1 is provided with a first matching groove 12 and a second matching groove 13 on two end surfaces opposite to each other in the first direction, the first matching groove 12 and the second matching groove 13 are both connected to the first through hole 11, wherein a lining is arranged in the first matching groove 12 The sleeve main spring 6, the second matching groove 13 is used to match with the shock absorber shell; the shell 2 is arranged in an annular shape, and the shell 2 is sleeved on the peripheral side of the mounting bracket 1 to jointly limit an accommodating cavity 5 with the shell 2; the rolling device 3 is arranged in the accommodating cavity 5, and is in contact with the mounting bracket 1 and the shell 2, so that the mounting bracket 1 and the shell 2 can rotate relative to each other; the end cover 4 is arranged on one side of the mounting bracket 1 along the first direction, and is used to cover the sleeve main spring 6, and is used to allow the shock absorber piston rod to pass through.

[0050] It should be noted that the present invention does not limit the shape of the first matching groove 12 and the second matching groove 13, which can be selected according to actual needs and can be square. In this embodiment, the shape of the first matching groove 12 and the second matching groove 13 is circular, so as to reasonably distribute the bearing pressure and better adapt to the automobile shock absorber.

[0051] It is understandable that the automobile shock absorber will deform when it is subjected to pressure movement. For this reason, a bushing main spring 6 is arranged in the first matching groove 12 to flexibly release the deformation generated during the movement of the shock absorber and reduce the loss of the shock absorber.

[0052] In addition, during the compression and rebound deformation of the spring, the terminal end of the spring will also undergo a certain rotational movement. In order to reduce this movement friction, in one embodiment of the present invention, the shell 2 and the mounting bracket 1 jointly limit an accommodating cavity 5, and the rolling device 3 is arranged in the accommodating cavity 5, so that the mounting bracket 1 and the shell 2 can rotate relative to each other and reduce the rotational friction.

[0053] In the technical solution of the present invention, a first through hole 11 is opened on the mounting bracket 1 for the shock absorber piston rod to pass through, and a bushing main spring 6 is placed in the first matching groove 12, so as to flexibly release the deformation generated during the movement of the shock absorber and reduce the loss of the shock absorber. The second matching groove 13 is used to cooperate with the shock absorber spring. In addition, the shell 2 and the mounting bracket 1 jointly limit an accommodating chamber 5, and the rolling device 3 is arranged in the accommodating chamber 5, so that the mounting bracket 1 and the shell 2 can rotate relative to each other to reduce the friction generated by the movement. The end cover 4 is arranged on one side of the mounting bracket 1 along the first direction, covers the bushing main spring 6, and is used for the shock absorber piston rod to pass through. Through such an arrangement, the automobile shock absorber upper support 100 with an integrated bearing integrates the automobile shock absorber bearing with the upper support, can simultaneously realize the connection with the shock absorber piston rod, bear the role of transmitting the spring elastic force, the piston rod damping force and the buffer block compression force, reduce the occupied space, and facilitate installation.

[0054] See also Figure 2 In one embodiment of the present invention, in order to better fix the upper support 100 of the automobile shock absorber with the integrated bearing, the mounting bracket 1 includes a first section 14 and a second section 15 which are successively reduced in size on the outside, the housing 2 is sleeved on the second section 15, and the portion of the first section 14 protruding from the second section 15 is used for bolt connection and fixation; by providing the first section 14 on the mounting bracket 1, the mounting bracket 1 can be connected with bolts and fixed to the automobile by bolts, thereby improving the stability of the upper support 100 of the automobile shock absorber with the integrated bearing.

[0055] Specifically, the first section 14 of the mounting bracket 1 is provided with a plurality of second through holes 16 along the first direction, and the plurality of second through holes 16 are spaced around the center of the mounting bracket 1. The upper support 100 of the automobile shock absorber with an integrated bearing also includes a threaded sleeve 18, which is embedded in the second through hole 16, and a threaded hole is provided in the middle of the threaded sleeve 18 along the first direction for threaded connection with a bolt. The present invention does not limit the number of the second through holes 16. In the present embodiment, the number of the second through holes 16 is four, and they are evenly spaced around the center of the mounting bracket 1, thereby reducing the component force along the second direction and ensuring a stable connection. In order to achieve a more stable connection, more second through holes 16 can also be adaptively provided.

[0056] See also Figures 2 to 3 In one embodiment of the present invention, the second section includes a first main body 151 and a second main body 152 whose outer dimensions decrease in sequence, and the shell 2 includes two first straight side sections 21 and a second straight side section 22; the two first straight side sections 21 extend along the first direction and are staggered in the second direction, one of the first straight side sections 21 is sleeved on the outer periphery of the first main body 151, and the other first straight side section 21 is correspondingly located on the outer periphery of the second main body 152; the second straight side section 22 extends along the second direction and is respectively connected to the ends of the two first straight side sections 21; wherein the two first straight side sections 21, the second straight side section 22 and a part of the second section 15 are jointly enclosed to form the accommodating cavity 5; by such an arrangement, while enclosing the accommodating cavity 5, it is also ensured that the shell 2 and the mounting bracket 1 are more closely fitted, thereby reducing the occupied space.

[0057] Specifically, see Figure 6 In one embodiment of the present invention, a portion of the first straight edge section 21 disposed on the outer periphery of the second main body 152 also extends along the second direction toward the center of the mounting bracket 1 with a protrusion 211, and a snap groove 17 is formed at a corresponding position of the second main body 152 of the mounting bracket 1, and the protrusion 221 is snapped into the snap groove 17, thereby forming a snap structure, so that the shell 2 is sleeved on the peripheral side surface of the mounting bracket 1.

[0058] See also Figure 5In one embodiment of the present invention, the rolling device 3 includes a first matching block 31, a second matching block 32 and a plurality of rolling parts 33; the first matching block 31 has two opposite side surfaces, one side is in contact with the part of the mounting bracket 1 forming the accommodating cavity 5, and the other side is provided with a first track 311; the second matching block 32 has two opposite side surfaces, one side is in contact with the part of the housing 2 forming the accommodating cavity 5, and the other side is provided with a second track 321, and the second track 321 and the first track 311 jointly limit a rolling groove; the plurality of rolling parts 33 are arranged in the rolling groove and can be rotatably installed in the rolling groove, wherein the rolling part 33 can be a roller, so as to bear a larger axial load. In this embodiment, the rolling part 33 is a ball, which has a lower cost and a smaller size than a roller, and can better compress the space.

[0059] Furthermore, when the rolling portion 33 is a ball, in order to better limit the position of the ball, the rolling device 3 also includes a retaining frame 34, and the retaining frame 34 is arranged corresponding to each of the balls to ensure that the balls are evenly distributed, prevent the balls from contacting each other, and reduce friction and wear.

[0060] In addition, one side of the first matching block 31 can be separately contacted with the first section 14 of the mounting bracket 1, and one side of the second matching block 32 can be separately contacted with the first bending section 23, thereby bearing the load in the first direction; and in the present embodiment, it can be understood that the automobile will inevitably produce shaking in other directions during driving. For this reason, the side of the first matching block 31 that contacts the part of the mounting bracket 1 that forms the accommodating cavity 5 is simultaneously connected to the second section 15 and the part of the first section 14 that protrudes from the second section 15; the side of the second matching portion that contacts the part of the shell 2 that forms the accommodating cavity 5 is simultaneously connected to the first straight edge section 21 and the first bending section 23, so that the rolling groove forms a certain angle with the first direction, so that the rolling portion 33 can simultaneously bear loads in other directions, further enhancing the vibration reduction effect; it should be noted that the present invention does not limit the specific angle of the angle, and it can be set according to the actual load distribution.

[0061] See also Figure 5In one embodiment of the present invention, the bushing main spring 6 includes a first skeleton 61, a second skeleton 62 and a connecting portion 63. The first skeleton 61 is arranged in an annular shape and includes two end surfaces along the first direction. The outer wall of the first skeleton 61 abuts against the wall surface of the first matching groove 12; the second skeleton 62 is arranged in an annular shape and is located on the inner side of the first skeleton 61, and is connected to the first skeleton 61 through an elastically arranged connecting portion, wherein at least a portion of the connecting portion 63 extends out of the two end surfaces, and the portion of the connecting portion 63 extending out of the two end surfaces abuts against the end cover 4.

[0062] Specifically, the connecting portion 63 is an elastic material, which may be an elastic plastic. In the present embodiment, the connecting portion 63 is rubber, so as to flexibly release the deformation generated during the movement of the shock absorber and reduce the loss of the shock absorber. In addition, it can be understood that when installing, the bushing main spring 6 is first pressed into the first matching groove 12, and then the end cover 4 is welded to the end face of the mounting bracket 1, and the part extending from the two end faces through the connecting portion 63 abuts against the end cover 4, so that the connecting portion 63 is pressed into the first matching groove 12 with a pre-tightening force, so as to stabilize the connection between the bushing main spring 6 and the first matching groove 12. In another embodiment of the present invention, the connecting portion 63 may also directly abut against the first matching groove 12, so as to further reduce the weight.

[0063] Furthermore, in one embodiment of the present invention, the connecting portion 63 is arranged to at least wrap a portion of the two end surfaces of the second skeleton 62 along the first direction, so that the second skeleton 62 can also support the connecting portion 63 in the first direction, thereby improving the stability of the bushing main spring 6.

[0064] Since the car will inevitably shake in other directions during driving, the piston rod of the car will also shake along the second direction. For this reason, in one embodiment of the present invention, the connecting portion 63 is provided with annular grooves 631 on the two side surfaces opposite to each other in the first direction, so that when the piston rod shakes along the second direction, the piston rod squeezes the connecting portion 63 through the second skeleton 62, and the connecting portion 63 can avoid the annular groove 631, thereby flexibly releasing the movement in other directions generated by the shock absorber and better protecting the piston rod.

[0065] In order to simplify the structure and facilitate processing, when the connecting part material is rubber, the first skeleton 61, the second skeleton 62 and the connecting part 63 can be formed by integrated vulcanization, so that they can be manufactured as a whole, thereby simplifying the manufacturing process and reducing costs. Moreover, since it is a one-time molding, the consistency of the size and shape of each product is ensured, thereby improving the overall performance of the bushing main spring 6.

[0066] It is understandable that the rolling device 3 is the main pressure-bearing part, and the strength of the part of the mounting bracket 1 that forms the accommodating cavity 5 may be insufficient. For this reason, in one embodiment of the present invention, the upper support 100 of the automobile shock absorber with an integrated bearing also includes a first reinforcing lining 7, which is embedded in the mounting bracket 1 and arranged corresponding to the rolling device 3. Specifically, when the part of the mounting bracket 1 that forms the accommodating cavity 5 includes the second section 15 and the part of the first section 14 protruding from the second section 15, the first reinforcing lining 7 can also be correspondingly set to an L-shape, so as to better reinforce the structure without increasing the weight too much.

[0067] Please refer to the figure, in another embodiment of the present invention, the upper support 100 of the automobile shock absorber with integrated bearing further includes a second reinforcing lining 8, which is embedded in the shell 2 and arranged corresponding to the rolling device 3. Specifically, when the part of the shell 2 forming the accommodating cavity 5 includes the first straight edge section 21 and the first bending section 23, the second reinforcing lining 8 can also be correspondingly arranged in an L-shape. In addition, the first reinforcing lining 7 and the second reinforcing lining 8 can be arranged selectively, and in this embodiment, they can also be arranged together, so as to better reinforce and increase the reliability of the upper support 100 of the automobile shock absorber with integrated bearing.

[0068] Furthermore, in order to facilitate processing and installation, in one embodiment of the present invention, the mounting bracket 1, the first reinforcing liner 7 and the threaded sleeve 18 can be integrally formed by injection molding. Specifically, the mounting bracket 1 is formed by positioning the first reinforcing liner 7 and the threaded sleeve 18 in a mold, and then the glass fiber nylon material is injected to form the mounting bracket 1, thereby achieving that the first reinforcing liner 7 and the threaded sleeve 18 are stably embedded in the mounting bracket 1. Similarly, the shell 2 and the second reinforcing liner 8 can be integrally formed by injection molding. The second reinforcing liner 8 is positioned in a mold, and then the glass fiber nylon material is injected to form the shell 2, thereby achieving that the second reinforcing liner 8 is stably embedded in the shell 2.

[0069] In one embodiment of the present invention, it should be noted that glass fiber nylon is a composite material that enhances the performance of nylon substrate by adding glass fiber. This material combines the excellent mechanical properties of nylon and the reinforcing characteristics of glass fiber, has high strength and high wear resistance, and is lighter than metal materials; therefore, at least one of the mounting bracket 1, the housing 2, the end cover 4, and the retaining frame 34 is made of glass fiber nylon material; on the basis of ensuring the strength required by the shock absorber, the weight is reduced. It can be understood that the material of the mounting bracket 1, the housing 2, the end cover 4, and the retaining frame 34 is selected as glass fiber nylon material, and in order to reduce more weight, the amount of the glass fiber nylon material used can also be increased.

[0070] In addition, in one embodiment of the present invention, the load borne by the end face of the mounting bracket 1 and the end cover 4 is relatively small, and the mounting bracket 1 and the end cover 4 are provided with a plurality of weight-reducing holes 9 in a special shape arranged in the first direction and arranged at intervals along the second direction, so as to further reduce the weight of the support 100 on the automobile shock absorber of the integrated bearing. It should be noted that the weight-reducing holes 9 are in a special shape to prevent them from cooperating with other parts during processing. In addition, the present invention does not limit the specific number of the weight-reducing holes 9, which can be set according to the actual load distribution.

[0071] The present invention also proposes a shock absorber, which includes an automobile shock absorber upper support 100 with an integrated bearing. The specific structure of the automobile shock absorber upper support 100 with an integrated bearing refers to the above-mentioned embodiment. Since the shock absorber adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0072] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
