Description

Technical Field

[0001] The utility model relates to the technical field of bicycle suspension systems, in particular to a bicycle shock absorbing mechanism. Background Art

[0002] Bicycle suspension is an important part of the overall design of the bicycle, and plays a vital role in the comfort and performance of the bicycle. For common mountain bikes, they are roughly divided into hard-tail mountain bikes and soft-tail mountain bikes. Among them, the suspension of hard-tail mountain bikes is an integrated shape and has no rear shock absorber, while the suspension of soft-tail mountain bikes is a multi-link structure, and a pivot point is set on the frame to enable the rear end of the bicycle to move up and down.

[0003] In comparison, soft-tail mountain bikes have both suspension front forks and rear shock absorbers, which have better shock absorption effects. In actual riding, different shock absorbers are needed to meet different shock absorption requirements for different riding routes, and riders with different styles will adjust or choose shock absorbers according to their different riding styles.

[0004] When existing bicycle suspensions or bodies are designed and manufactured, they are only suitable for installing shock absorbers of fixed sizes due to their fixed structures, and cannot be adapted to shock absorbers of different specifications, resulting in poor versatility. Based on this, a bicycle shock absorbing mechanism is needed that can adapt to shock absorbers of different specifications without replacing the frame. Utility Model Content

[0007] 2. Specific technical solutions

[0008] A bicycle shock absorbing mechanism comprises a shock absorber and a connecting member, which is arranged at the connection between the front frame and the rear frame of the bicycle, wherein the front frame comprises a seat tube and a front lower tube, and the connecting member comprises a main pivot hole and a second pivot hole and a third pivot hole arranged on both sides of the main pivot hole, wherein the second pivot hole is located on the side where the front frame is located; the connecting member is pivotally connected to the middle and upper section of the seat tube through the main pivot hole, the second pivot hole is used for pivotally connecting to one end of the shock absorber, the other end of the shock absorber is pivotally connected to a side of the front lower tube close to the seat tube, and the third pivot hole is used for connecting to the rear frame.

[0009] Implementation principle and working principle: In this scheme, a connecting member is provided at the connection between the front frame and the rear frame, wherein the connecting member is pivotally connected to the seat tube through a main pivot hole, that is, the second pivot hole and the third pivot hole of the connecting member are pivotally connected to the shock absorber and the rear frame respectively. The advantage of such a setting is that when the frame is subjected to force, the force will be transmitted to the shock absorber through the rotation of the connecting member to achieve shock absorption; wherein, when it is necessary to replace shock absorbers of different sizes and specifications, it is only necessary to rotate the connecting member and adjust the position of the second pivot hole of the rotating member to change the installation position of the shock absorber, thereby meeting the adaptation of shock absorbers of different sizes and specifications.

[0010] Preferably, the connecting member comprises mounting plates symmetrically arranged on both sides of the longitudinal section of the seat tube, and a supporting tube is arranged between the two mounting plates. The beneficial effect of this preferred embodiment is that the connection strength of the connecting member can be effectively improved through the cooperation of the connecting member and the pivots at the pivot joints of each pivot hole, which is also beneficial to the dispersed transmission of force when the vehicle body is subjected to force.

[0011] Preferably, a groove is provided on the opposite side of the mounting plate, the groove extends from the second pivot hole to the third pivot hole, and the groove is integrally formed on the surface of the mounting plate; the two ends of the support tube are respectively connected to the bottom of the grooves of the mounting plates on both sides; the beneficial effect of this preferred embodiment is that the weight of the connecting part can be effectively reduced by setting the grooves on the surface of the mounting plate, which is beneficial to the lightweight of the vehicle body.

[0012] Preferably, the angle formed by the line connecting the hole centers of the main pivot hole and the second pivot hole, and the angle formed by the line connecting the hole centers of the main pivot hole and the third pivot hole is 128°-134°; the beneficial effect of this preferred embodiment is that with the setting of this parameter, force can be more easily transmitted to the shock absorber through the connecting piece during riding.

[0013] Preferably, a mounting seat is provided on one side of the front lower tube close to the seat tube, a first mounting hole is provided on the mounting seat, the first mounting hole is an axisymmetric mounting hole, a mounting module matched with the mounting hole is provided in the first mounting hole, a second mounting hole is provided on one side of the mounting module; the shock absorber is pivotally connected at the second mounting hole of the mounting module;

[0014] The beneficial effect of this preferred embodiment is that the bottom of the shock absorber is pivotally connected to the second mounting hole of the mounting module. Since the mounting module and the mounting hole it matches are symmetrical, the position of the second mounting hole can be changed by replacing the position of the mounting module, thereby changing the mounting position of the bottom of the shock absorber, that is, the mounting position or angle of the shock absorber, thereby changing the transmission of force on the frame and achieving a change in the shock absorbing effect.

[0015] Preferably, the first mounting hole is an oblong hole, and the second mounting hole is arranged at one end of the oblong hole in the length direction; the side of the mounting module that matches the first mounting hole shrinks inwardly to form a step shape;

[0016] The advantageous effects of this preferred embodiment are as follows: the first mounting hole is an oblong hole, which is convenient for processing, and the oblong hole is evenly stressed and has a longer service life; the stepped design of the mounting module enables the mounting module to be stably mounted in the first mounting hole by pivoting.

[0017] The beneficial effects of the utility model are:

[0018] 1. By changing the angle of the connecting piece on the seat tube, the distance between the second pivot hole of the connecting piece and the front lower tube can be changed, which can meet the installation requirements of shock absorbers of different sizes and specifications, and has strong versatility.

[0019] 2. Through the design of the installation module, the installation angle of the shock absorber on the front frame can be changed, the force transmission path can be changed, and then the shock absorption effect can be changed, so as to meet different shock absorption requirements without changing the frame and shock absorber.

[0030] Working principle: When it is necessary to replace the shock absorber 100 of different sizes, it is only necessary to rotate the connecting member 101 to change the distance between the second pivot hole 107 and the front lower tube 104, which can well cope with the installation of shock absorbers 100 of different sizes to meet the shock absorption requirements of different riding routes and riding styles.

[0031] During implementation, the connector 101 includes two mounting plates 108, wherein the mounting plates 108 are symmetrically arranged on both sides of the longitudinal section of the seat tube 103, specifically, the two mounting plates 108 are symmetrically pivoted on both sides of the pivot seat through the main pivot holes 105 thereon; wherein, the two mounting plates 108 have support tubes 109 welded or integrally formed on opposite sides thereof; the two mounting plates 108 have grooves 110 formed on the sides away from each other, wherein the grooves 110 extend from the left side to the right side of the connector 101, and the two ends of the support tubes 109 are connected to the bottom of the grooves 110 and communicate with the grooves 110; in this solution, the arrangement of the support tubes 109 and the grooves 110 is conducive to the lightweight of the connector 101 and the lightweight of the vehicle body, and the joint action of the main pivot hole 105, the pivot of the second pivot hole 107 and the support tubes 109 can effectively improve the strength of the connector 101 and the front frame 102 and the rear frame.

[0032] During implementation, the angle between the center of the main pivot hole 105 and the centers of the second pivot holes 107 and the third pivot holes 106 on both sides is 128°-134°. With this angle setting, during riding, force is more easily transmitted to the shock absorber 100 through the connecting piece 101, and the shock absorption effect is better.
