Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

As shown in fig. 1 to 3, an embodiment of the present invention provides a suspension structure, including:

a suspension body 100, the suspension body 100 including a core 110, the core 110 having a first surface 111, a second surface 112 disposed opposite to the first surface 111, and a first opening 113 penetrating both the first surface 111 and the second surface 112; the hole wall of the first hole 113 is provided with a first internal thread;

a threaded sleeve 200, wherein a first external thread matched with the first internal thread is arranged on the outer peripheral surface of the threaded sleeve 200, and the threaded sleeve 200 can be installed into the first opening 113 from the second surface 112; the threaded sleeve 200 is provided with a second hole 210, and the hole wall of the second hole 210 is provided with a second internal thread; wherein the first external thread and the second internal thread have opposite rotation directions;

Wherein the second end 320 is capable of penetrating the first aperture 113 from the first surface 111 and fitting into the second aperture 210; a clamping space is formed between the first end 310 and the first surface 111.

The core 110 may be a rigid member, in which a first opening 113 is formed for installing the center bolt 300. referring to fig. 4, the center bolt 300 includes a first end 310 and a second end 320, the first end 310 is a bolt head, and the second end 320 is used for connecting with the thread bushing 200 located below. The thread housing 200 has a first external thread and a second internal thread with opposite directions, and when the center bolt 300 is rotated in a specific direction and moved downward in the thread housing 200, the thread housing 200 moves upward or tends to move upward with respect to the core 110. The clamping space formed between the bolt head and the first surface 111 may be used for mounting the carriage. In practical applications, the distance between the bolt head and the threaded sleeve 200 can be shortened by rotating the bolt head back and forth mainly in a specific direction, so that the vehicle frame is pressed against the core 110 or a support cushion plate arranged on the core 110 through the bolt head. Of course, if the rotation process of the bolt head is relatively smooth, the bolt head can be rotated in the same direction all the time.

In this embodiment, the reverse internal and external threads are provided on the threaded sleeve, so that the threaded sleeve can simultaneously generate a movement or a movement trend toward the bolt head during the process of screwing the central bolt into the threaded sleeve. In practical application, the clamping and fixing of the parts assembled in the clamping space can be completed only by operating the bolt head, so that the operation is convenient; in addition, because the threaded sleeve does not need to be operated, even if the space where the threaded sleeve is located is limited and even the space is difficult to reach by manpower, the connection strength and the assembly quality between the central bolt and the threaded sleeve can still be effectively ensured.

The spacing pad 410 can limit the downward displacement of the rubber layer 120.

Optionally, a gap is provided between the rubber layer 120 and the limiting pad 410. The provision of the gap prevents the deformation of the rubber layer 120 from being excessively restricted, thereby contributing to an increase in the vibration damping effect of the rubber layer 120.

Optionally, a connection platform 130 is embedded in the radially outer surface of the rubber layer 120.

The connecting platform 130 may be vulcanized with the rubber layer 120, and the embedded structure can improve the connecting strength between the two. The attachment platform 130 is used to integrally mount the suspension structure to a vehicle frame or other structure. In a preferred embodiment, as shown in FIG. 1, the attachment platform 130 is provided with a plurality of fastening bolts 131 to facilitate attachment to a vehicle frame or other structure.

Optionally, the rubber layer 120 covers at least one end of the connecting platform 130 away from the first surface 111. Namely, the connecting platform 130 and the limiting cushion plate 410 can be separated by the rubber layer 120, so that the two rigid structures are prevented from directly impacting, the vibration reduction effect is prevented from being influenced, and the service life of the connecting platform is prolonged.

Optionally, a hollowed-out structure 121 is disposed on an end surface of the rubber layer 120 away from the first surface 111.

As shown in fig. 3, the rubber layer 120 has an annular hollow on the bottom surface thereof for adjusting the rigidity of the rubber layer 120 as a whole, and also facilitates the rubber layer 120 to be easily deformed to adapt to the assembly, for example, the rubber layer 120 may need to be deformed by itself to make its upper end flush with the first surface 111 of the core 110 during the assembly to form a stable support for the components in the clamping space. Of course, the rubber layer 120 may not be provided with the hollow structure 121 according to the practical application requirement, for example, when the strength meets the use requirement.

Optionally, a first supporting cushion plate 420 and a second supporting cushion plate 430 which are oppositely arranged are arranged in the clamping space; the center bolt 300 penetrates the first support pad 420 and the second support pad 430 in an axial extending direction. The first supporting cushion plate 420 and the second supporting cushion plate 430 are provided with a gap for clamping a vehicle body or other structures, and through the arrangement of the two supporting cushion plates, a contact surface for clamping can be enlarged, and the stability of clamping and fixing is improved.
