Description

Technical Field

[0001] The utility model relates to the technical field of bicycle brackets, and more specifically, to a fixing structure for a bicycle bracket. Background Art

[0002] With the increasing popularity of cycling, urban residents are increasingly inclined to choose bicycles as a means of transportation for short trips in their daily lives. However, due to the limitations of urban road planning and the specificity of cycling venues, residents often need to transport their bicycles from their place of residence to a suitable location for cycling. In addition, modern families may own multiple bicycles to meet the needs of different family members or different cycling activities. To solve this problem, a bicycle bracket that can be clamped on a car has emerged on the market, which allows users to transport their bicycles to the destination safely and conveniently.

[0003] To ensure the stability and safety of the bicycle during transportation, structures such as cable ties or straps are usually equipped on the bracket. These structures can fix the bicycle tire to the bracket, but structures such as cable ties or straps can only prevent the bicycle from falling off, and the connection between the bicycle and the bracket is still loose. Therefore, a clamping device is generally required to fix the bicycle to the bracket itself. Due to reasons such as different sizes and shapes of bicycles, the connection positions between the bracket and the bicycle are not fixed, including but not limited to positions such as the horizontal bar, diagonal bar, upright column, and even the tire of the bicycle. However, the clamping devices in the prior art are relatively cumbersome to operate and cannot achieve quick disassembly and installation. Summary of the Utility Model

[0004] The main purpose of the present utility model is to provide a fixing structure for a bicycle bracket, which can solve the problem that the clamping devices in the prior art are relatively cumbersome to operate and cannot achieve quick disassembly and installation.

[0005] To achieve the above purpose, the present utility model provides a fixing structure for a bicycle bracket, including: an installation structure having a relatively arranged first end and second end; a first claw assembly installed at the first end of the installation structure, the first claw assembly having a first released state and a first clamped state; a second claw assembly installed at the second end of the installation structure, the second claw assembly having a second released state and a second clamped state, the second claw assembly further having a free state and a constrained state, and when the second claw assembly is in the constrained state, the second claw assembly remains in the second clamped state; a driving structure, when the second claw assembly is in the free state and the second claw assembly is in the second released state, the driving structure drives the first claw assembly to switch from the first released state to the first clamped state, and when the second claw assembly is in the free state and the second claw assembly is in the second clamped state, the driving structure drives the first claw assembly to switch from the first clamped state to the first released state.

[0006] Further, the driving structure includes a moving part and a transmission part. The moving part is mounted on the mounting structure and can move relative to the mounting structure between the first jaw assembly and the second jaw assembly. The first end of the transmission part is hinged to the moving part, and the second end of the transmission part is hinged to the first jaw assembly, so that the first jaw assembly can be switched between a first released state and a first clamped state.

[0007] Further, the first jaw assembly includes two hinged first jaws. One of the two first jaws is fixedly connected to the mounting structure. The first end of the transmission part is hinged to the moving part, and the second end of the transmission part is hinged to the other of the two first jaws. The hinge point between the first end of the transmission part and the moving part is the first hinge point, and the hinge point between the second end of the transmission part and the other first jaw of the two first jaws is the second hinge point. The connection line between the first hinge point and the second hinge point is the first connection line, and the hinge point between the two first jaws is the third hinge point, and the third hinge point is located below the first connection line; or, the first jaw assembly includes two hinged first jaws, and at least one transmission part is hinged to each of the two first jaws.

[0008] Further, the driving structure further includes a first elastic structure. The first elastic structure is sleeved on the mounting structure and is limited between the first jaw assembly and the moving part. When the second jaw assembly is in the second released state, the first elastic structure is compressed. When the second jaw assembly is in the free state and the second jaw assembly is in the second clamped state, the first elastic structure can provide an elastic force for the moving part to move in a direction away from the first jaw assembly.

[0009] Further, the second jaw assembly includes two hinged second jaws. The two second jaws are sequentially sleeved on the second end of the mounting structure along the length direction of the mounting structure. Among the two second jaws, the second jaw close to the first jaw assembly can provide an acting force for the moving part to move toward the side where the first jaw assembly is located.

[0010] Further, the second jaw assembly further includes a first connecting member and a second elastic structure. One ends of the two second jaws are hinged through the first connecting member. The second elastic structure is mounted on the first connecting member, and the second elastic structure can provide an elastic force for the two second jaws to move away from each other, and the elastic force of the second elastic structure is greater than the elastic force of the first elastic structure.

[0011] Further, the second jaw assembly further includes a second elastic structure. The second elastic structure is sleeved on the mounting structure, and both ends of the second elastic structure are in contact with the two second jaws respectively. The second elastic structure can provide an elastic force for the two second jaws to move away from each other, and the elastic force of the second elastic structure is greater than the elastic force of the first elastic structure.

[0012] Further, first long holes are provided on both of the two second holding claws, and the second end of the mounting structure sequentially passes through the two first long holes. Among the two second holding claws, a first convex structure is provided on the second holding claw close to the first holding claw assembly, and the first convex structure can be in abutting cooperation with the end of the moving part away from the first holding claw assembly.

[0013] Further, the fixing structure for the bicycle bracket further includes a constraint limiting structure. The constraint limiting structure is mounted on the second end of the mounting structure. The constraint limiting structure is located on the side of the second holding claw assembly away from the first holding claw assembly and can move relative to the mounting structure in a direction close to or away from the first holding claw assembly, so that the second holding claw assembly can be switched between a constrained state and a free state.

[0014] Further, among the two second holding claws, a second convex structure is provided on the second holding claw away from the first holding claw assembly, and the second convex structure can be in abutting cooperation with the end of the constraint limiting structure facing the second holding claw assembly, so that the second holding claw assembly is in a constrained state.

[0015] Applying the technical solution of the present utility model, there are provided an installation structure, a first jaw assembly and a second jaw assembly. One of the first jaw assembly and the second jaw assembly is clamped and fixed to the bicycle rack at the rear of the vehicle, and the other of the first jaw assembly and the second jaw assembly is clamped and fixed to the bicycle. When it is necessary to fix the bicycle to the bicycle rack at the rear of the vehicle, first, the second jaw assembly is in a free state, and then the second jaw assembly is in a second clamping state. At this time, the driving structure drives the first jaw assembly to switch from the first clamping state to the first releasing state. At this time, one of the beam on the bicycle rack at the rear of the vehicle and the beam of the bicycle is clamped into the first jaw assembly, and then the second jaw assembly is in a second releasing state. The driving structure drives the first jaw assembly to switch from the first releasing state to the first clamping state, so as to realize the clamping and fixing of the first jaw assembly to one of the bicycle rack at the rear of the vehicle and the bicycle. Then, the other of the beam on the bicycle rack at the rear of the vehicle and the beam of the bicycle is clamped into the second jaw assembly, and the second jaw assembly is in a constrained state, so as to realize the clamping and fixing of the second jaw assembly to the other of the bicycle and the bicycle rack at the rear of the vehicle. When it is necessary to remove the bicycle and disassemble the bicycle rack with the fixing structure, first, the second jaw assembly is in a free state. At this time, the second jaw assembly can freely switch between the second clamping state and the second releasing state. Then, the second jaw assembly is in a second releasing state, so as to realize the separation of the second jaw assembly from one of the bicycle and the bicycle rack at the rear of the vehicle. Then, the second jaw assembly is in a second clamping state again. At this time, the driving structure drives the first jaw assembly to switch from the first clamping state to the first releasing state, so as to realize the separation of the first jaw assembly from the other of the bicycle rack at the rear of the vehicle and the bicycle, thereby realizing the disassembly of the bicycle rack with the fixing structure.

[0026] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] Combined with reference to Figures 1 to 7As shown in the figure, the present utility model provides a fixing structure for a bicycle bracket. The fixing structure for the bicycle bracket includes: an installation structure 10 having a first end and a second end arranged opposite to each other; a first claw assembly 20 installed at the first end of the installation structure 10, the first claw assembly 20 having a first released state and a first clamped state; a second claw assembly 30 installed at the second end of the installation structure 10, the second claw assembly 30 having a second released state and a second clamped state, the second claw assembly 30 further having a free state and a constrained state, and when the second claw assembly 30 is in the constrained state, the second claw assembly 30 remains in the second clamped state; a driving structure 40, when the second claw assembly 30 is in the free state and the second claw assembly 30 is in the second released state, the driving structure 40 drives the first claw assembly 20 to switch from the first released state to the first clamped state, and when the second claw assembly 30 is in the free state and the second claw assembly 30 is in the second clamped state, the driving structure 40 drives the first claw assembly 20 to switch from the first clamped state to the first released state.

[0028] In this embodiment, when the second claw assembly 30 is in the free state, the second claw assembly 30 can freely switch between the second released state and the second clamped state. When the second claw assembly 30 is in the constrained state, the second claw assembly 30 cannot freely switch between the second released state and the second clamped state. At this time, the second claw assembly 30 remains in the second clamped state. The fixing structure for the bicycle bracket of the present application is used to fix a bicycle on a rear bicycle bracket. One of the first claw assembly 20 and the second claw assembly 30 is clamped and fixed to the rear bicycle bracket, and the other of the first claw assembly 20 and the second claw assembly 30 is clamped and fixed to the bicycle.

[0029] For the convenience of description, it is assumed that the first clamping jaw assembly 20 is used to clamp and fix the bicycle rack at the rear of the vehicle, and the second clamping jaw assembly 30 is used to clamp and fix the bicycle. During use, the second clamping jaw assembly 30 is in a free state. Then, pinch the second clamping jaw assembly 30 by hand to make the second clamping jaw assembly 30 in the second clamping state. At this time, the driving structure 40 drives the first clamping jaw assembly 20 to switch from the first clamping state to the first releasing state, moves the first clamping jaw assembly 20 to the bicycle rack at the rear of the vehicle, and then clips the beam of the bicycle rack at the rear of the vehicle into the clamping space of the first clamping jaw assembly 20. Then, release the second clamping jaw assembly 30 by hand to make the second clamping jaw assembly 30 in the second releasing state. At this time, the driving structure 40 drives the first clamping jaw assembly 20 to switch from the first releasing state to the first clamping state, realizing the clamping and fixing of the first clamping jaw assembly 20 and the bicycle rack at the rear of the vehicle. Then, move the part of the bicycle to be clamped into the clamping space of the second clamping jaw assembly 30 to make the second clamping jaw assembly 30 in a constrained state, realizing the clamping and fixing between the second clamping jaw assembly 30 and the bicycle. When it is necessary to remove the bicycle and disassemble the bicycle rack with the fixing structure, first, make the second clamping jaw assembly 30 in a free state. At this time, the second clamping jaw assembly 30 can freely switch between the second clamping state and the second releasing state. Then, make the second clamping jaw assembly 30 in the second releasing state to realize the separation between the second clamping jaw assembly 30 and the bicycle. Then, make the second clamping jaw assembly 30 in the second clamping state again. At this time, the driving structure 40 drives the first clamping jaw assembly 20 to switch from the first clamping state to the first releasing state, realizing the separation between the first clamping jaw assembly 20 and the bicycle rack at the rear of the vehicle, thereby realizing the disassembly of the bicycle rack with the fixing structure. As can be seen from the above, under the driving action of the driving structure 40, the linkage of the first clamping jaw assembly 20 and the second clamping jaw assembly 30 can be realized, the installation and disassembly of the fixing structure of the bicycle rack can be realized, and further the connection and fixation and disconnection between the bicycle and the bicycle rack at the rear of the vehicle can be realized. The entire installation and disassembly process does not require the use of other tools, the operation is relatively simple, the quick installation and disassembly of the fixing structure of the bicycle rack can be realized, and further the connection and fixation efficiency and disconnection efficiency between the bicycle and the bicycle rack at the rear of the vehicle can be improved.

[0030] Referring to Figures 1 to 7 As shown in the figure, in an embodiment of the present invention, the driving structure 40 includes a moving part 41 and a transmission part 42. The moving part 41 is installed on the installation structure 10 and can move relative to the installation structure 10 between the first clamping jaw assembly 20 and the second clamping jaw assembly 30. The first end of the transmission part 42 is hinged to the moving part 41, and the second end of the transmission part 42 is hinged to the first clamping jaw assembly 20, so that the first clamping jaw assembly 20 can be switched between the first releasing state and the first clamping state.

[0031] In this embodiment, taking Figure 1It is described that when the second gripper assembly 30 is in a free state and in the second released state, the moving part 41 moves relative to the mounting structure 10 towards the side where the first gripper assembly 20 is located. At this time, the transmission part 42 rotates counterclockwise to drive the first gripper assembly 20 to switch from the first released state to the first clamped state. When the second gripper assembly 30 is in a free state and in the second clamped state, the moving part 41 moves relative to the mounting structure 10 towards the side where the second gripper assembly 30 is located. At this time, the transmission part 42 rotates clockwise to drive the first gripper assembly 20 to switch from the first clamped state to the first released state.

[0032] Referring to Figures 1 to 7 As shown in the figure, in an embodiment of the present invention, the first gripper assembly 20 includes two hinged first grippers 21. One of the two first grippers 21 is fixedly connected to the mounting structure 10. The first end of the transmission part 42 is hinged to the moving part 41, and the second end of the transmission part 42 is hinged to the other of the two first grippers 21. The hinge point between the first end of the transmission part 42 and the moving part 41 is the first hinge point, and the hinge point between the second end of the transmission part 42 and the other first gripper 21 of the two first grippers 21 is the second hinge point. The connection line between the first hinge point and the second hinge point is the first connection line, and the hinge point between the two first grippers 21 is the third hinge point. The third hinge point is located below the first connection line.

[0033] In this embodiment, taking Figure 1 as an example for description, when the second gripper assembly 30 is in a free state and in the second released state, the moving part 41 moves relative to the mounting structure 10 towards the side where the first gripper assembly 20 is located, and the transmission part 42 rotates counterclockwise and drives the first gripper 21 hinged thereto to rotate counterclockwise. At this time, this first gripper 21 rotates towards the side where the first gripper 21 fixedly connected to the mounting structure 10 is located, thereby realizing the switching of the first gripper assembly 20 from the first released state to the first clamped state. When the second gripper assembly 30 is in a free state and in the second clamped state, the moving part 41 moves relative to the mounting structure 10 towards the side where the second gripper assembly 30 is located, and the transmission part 42 rotates clockwise and drives the first gripper 21 hinged thereto to rotate clockwise. At this time, this first gripper 21 rotates towards the side away from the first gripper 21 fixedly connected to the mounting structure 10, thereby realizing the switching of the first gripper assembly 20 from the first clamped state to the first released state.

[0034] In an embodiment of the present invention, the first gripper assembly 20 includes two hinged first grippers 21, and at least one transmission part 42 is hinged to each of the two first grippers 21.

[0035] In this embodiment, at least one transmission part 42 is hinged to each of the two first clamping claws 21. The transmission part 42 can drive the first clamping claw 21 hinged thereto to rotate clockwise or counterclockwise, thereby realizing the switching of the first clamping claw assembly 20 between the first clamping position and the first releasing position.

[0036] Referring to Figures 1 to 7 As shown, in an embodiment of the present invention, the driving structure 40 further includes a first elastic structure 43. The first elastic structure 43 is sleeved on the mounting structure 10. The first elastic structure 43 is limited between the first clamping claw assembly 20 and the moving part 41. When the second clamping claw assembly 30 is in the second releasing state, the first elastic structure 43 is compressed. When the second clamping claw assembly 30 is in the free state and the second clamping claw assembly 30 is in the second clamping state, the first elastic structure 43 can provide an elastic force for the moving part 41 to move in a direction away from the first clamping claw assembly 20.

[0037] In this embodiment, when the second clamping claw assembly 30 is in the second releasing state, the first elastic structure 43 is compressed. One end of the first elastic structure 43 abuts against the end of the first clamping claw assembly 20 facing the second clamping claw assembly 30, and the other end of the first elastic structure 43 abuts against the end of the moving part 41 away from the second clamping claw assembly 30. When the second clamping claw assembly 30 is in the free state and the second clamping claw assembly 30 is in the second clamping state, under the action of the elastic restoring force of the first elastic structure 43, the moving part 41 moves toward the side where the second clamping claw assembly 30 is located. Through the above settings, the switching of the first clamping claw assembly 20 from the first clamping state to the first releasing state can be realized.

[0038] In one embodiment, the first elastic structure 43 is a spring.

[0039] Referring to Figures 1 to 7 As shown, in an embodiment of the present invention, the second clamping claw assembly 30 includes two hinged second clamping claws 31. The two second clamping claws 31 are sequentially sleeved on the second end of the mounting structure 10 along the length direction of the mounting structure 10. Among the two second clamping claws 31, the second clamping claw 31 close to the first clamping claw assembly 20 can provide a force for the moving part 41 to move toward the side where the first clamping claw assembly 20 is located.

[0040] In this embodiment, the two second clamping claws 31 are hinged. When the second clamping claw assembly 30 is in the free state and the second clamping claw assembly 30 is in the second releasing state, under the push of the second clamping claw 31 close to the first clamping claw assembly 20, the moving part 41 can move toward the side where the first clamping claw 21 is located, thereby realizing the switching of the first clamping claw assembly 20 from the first releasing state to the first clamping state.

[0041] Referring to Figures 1 to 7As shown, in one embodiment of the utility model, the second claw assembly 30 also includes a first connecting member 32 and a second elastic structure 33, one end of the two second claws 31 is hinged through the first connecting member 32, the second elastic structure 33 is installed on the first connecting member 32, and the second elastic structure 33 can provide the two second claws 31 with an elastic force to move away from each other, and the elastic force of the second elastic structure 33 is greater than the elastic force of the first elastic structure 43.

[0042] In this embodiment, the second elastic structure 33 is sleeved on the first connecting member 32. Since the elastic force of the second elastic structure 33 is greater than the elastic force of the first elastic structure 43, when the second claw assembly 30 is in a free state, in the absence of an external force, the second elastic structure 33 can open the two second claws 31, so that the second claw assembly 30 is in a second loose state, and at this time, the first claw assembly 20 is in a first clamping state. When it is necessary to switch the second claw assembly 30 from the second loose state to the second clamping state, the two second claws 31 are manually pinched, and under the action of an external force, the two second claws 31 can overcome the elastic force of the second elastic structure 33 and rotate in a direction close to each other, thereby realizing the conversion of the second claw assembly 30 from the second loose state to the second clamping state.

[0043] In one embodiment, the second elastic structure 33 is a torsion spring.

[0044] See also Figures 1 to 5 As shown, in one embodiment of the utility model, the bicycle rack fixing structure further includes a second connecting member 24 and two third connecting members 60, the mounting structure 10 is a round rod, the moving part 41 is a sleeve, the sleeve is sleeved on the outer circumference of the round rod, and can move towards or away from the first claw assembly 20 under the action of the second claw assembly 30, the transmission part 42 is a connecting rod, one end of the two first claws 21 close to the second claw assembly 30 is hinged through the second connecting member 24, one of the two first claws 21 is fixedly connected to the mounting structure 10, and the other of the two first claws 21 is fixedly connected to the mounting structure 10. A first connecting portion 22 is provided on the sleeve, a first connecting hole 23 is provided on the first connecting portion 22, a second connecting portion 44 is provided on the end of the sleeve close to the first claw assembly 20, a second connecting portion 44 is provided on the second connecting portion 44, and third connecting holes 421 are provided at both ends of the connecting rod, one of the third connecting members 60 is penetrated through the second connecting hole 45 and the third connecting hole 421 at one end of the connecting rod to realize the hinge connection between the connecting rod and the sleeve, and the other third connecting member 60 is penetrated through the first connecting hole 23 and the third connecting hole 421 at the other end of the connecting rod to realize the hinge connection between the connecting rod and the first claw 21.

[0045] In one embodiment, the moving part 41 is a sleeve, which is sleeved on the mounting structure 10. A receiving groove 411 is provided at one end of the sleeve facing the first claw assembly 20. A limiting protrusion 211 is provided at one end of the first claw 21 fixedly connected to the mounting structure 10 and facing the second claw assembly 30. When the second claw assembly 30 is in a free state and the second claw assembly 30 is in a second released state, the first elastic structure 43 is completely located in the receiving groove 411, the limiting protrusion 211 extends into the receiving groove 411, one end of the first elastic structure 43 abuts against the limiting protrusion 211, and the other end of the first elastic structure 43 abuts against the bottom of the receiving groove 411.

[0046] In one embodiment, the second connecting member 24 and the third connecting member 60 are both pins.

[0047] In one embodiment of the utility model, the second claw assembly 30 also includes a second elastic structure 33, which is sleeved on the mounting structure 10, and the two ends of the second elastic structure 33 are respectively abutted against the two second claws 31. The second elastic structure 33 can provide the two second claws 31 with an elastic force to move away from each other, and the elastic force of the second elastic structure 33 is greater than the elastic force of the first elastic structure 43.

[0048] In this embodiment, the second elastic structure 33 is sleeved on the mounting structure 10 and is located between the two second claws 31. One end of the second elastic structure 33 abuts against one of the two second claws 31, and the other end of the second elastic structure 33 abuts against the other of the two second claws 31. Since the elastic force of the second elastic structure 33 is greater than the elastic force of the first elastic structure 43, when the second claw assembly 30 is in a free state and in the absence of external force, the second elastic structure 33 can open the two second claws 31, so that the second claw assembly 30 is in a second released state. At this time, the first claw assembly 20 is in the first clamping state. Tight state, when it is necessary to switch the second claw assembly 30 from the second released state to the second clamped state, manually pinch the two second claws 31, and under the action of external force, the two second claws 31 can overcome the elastic force of the second elastic structure 33 and rotate in the direction close to each other, thereby realizing the conversion of the second claw assembly 30 from the second released state to the second clamped state. At this time, the second elastic structure 33 is compressed. When the hand is released, under the action of the elastic restoring force of the second elastic structure 33, the two second claws 31 can rotate in the direction away from each other, thereby realizing the conversion of the second claw assembly 30 from the second clamped state to the second released state.

[0049] In one embodiment, the second elastic structure 33 is a compression spring.

[0050] See also Figures 1 to 7As shown, in an embodiment of the present utility model, first long holes are provided on both of the two second holding claws 31. The second end of the mounting structure 10 sequentially passes through the two first long holes. Among the two second holding claws 31, a first convex structure 311 is provided on the second holding claw 31 close to the first holding claw assembly 20, and the first convex structure 311 can be in abutting cooperation with one end of the moving part 41 away from the first holding claw assembly 20.

[0051] In this embodiment, first long holes are provided on both of the two second holding claws 31. The first long holes extend along the length direction of the second holding claws 31 where they are located. The provision of the first long holes can ensure the smooth rotation of the second holding claws 31. A first convex structure 311 is provided on the second holding claw 31 close to the first holding claw assembly 20. The provision of the first convex structure 311 can strengthen the structural strength of the abutting position with the moving part 41, and thus can extend the service life of the second holding claw 31 close to the first holding claw assembly 20.

[0052] Referring to Figures 1 to 7 As shown, in an embodiment of the present utility model, a second long hole 312 is provided on the first convex structure 311. The second long hole 312 is correspondingly provided with the first long hole on the second holding claw 31 where it is located, and the extending direction of the second long hole 312 is the same as the extending direction of the first long hole.

[0053] Referring to Figures 1 to 7 As shown, in an embodiment of the present utility model, the fixing structure for a bicycle bracket further includes a constraint and limit structure 50. The constraint and limit structure 50 is installed at the second end of the mounting structure 10. The constraint and limit structure 50 is located on the side of the second holding claw assembly 30 away from the first holding claw assembly 20, and can move relative to the mounting structure 10 in a direction close to or away from the first holding claw assembly 20, so that the second holding claw assembly 30 can be switched between a constrained state and a free state.

[0054] In this embodiment, when it is necessary for the second holding claw assembly 30 to be in a constrained state, the constraint and limit structure 50 is moved in a direction close to the first holding claw assembly 20 until one end of the constraint and limit structure 50 facing the second holding claw assembly 30 abuts against the second holding claw assembly 30. When it is necessary for the second holding claw assembly 30 to be in a free state, the constraint and limit structure 50 is moved in a direction away from the first holding claw assembly 20 until when the second holding claw assembly 30 is in the second released state, the constraint and limit structure 50 still does not contact the second holding claw assembly 30.

[0055] In an embodiment, the constraint and limit structure 50 is in threaded cooperation with the second end of the mounting structure 10. By rotating the constraint and limit structure 50, the constraint and limit structure 50 can move relative to the mounting structure 10 in a direction close to or away from the first holding claw assembly 20.

[0056] Referring toFigures 1 to 7 As shown, in an embodiment of the present utility model, among the two second clamping claws 31, a second convex structure 313 is provided on the second clamping claw 31 far from the first clamping claw assembly 20. The second convex structure 313 can be in abutting cooperation with one end of the constraint and limit structure 50 facing the second clamping claw assembly 30, so that the second clamping claw assembly 30 is in a constrained state.

[0057] In this embodiment, a second convex structure 313 is provided on the second clamping claw 31 far from the first clamping claw assembly 20. The provision of the second convex structure 313 can strengthen the structural strength of the position where it abuts against the constraint and limit structure 50, and thus can extend the service life of the second clamping claw 31 far from the first clamping claw assembly 20.

[0058] In an embodiment of the present utility model, a fourth long hole is provided on the second convex structure 313. The fourth long hole is correspondingly arranged with the first long hole on the second clamping claw 31 where it is located, and the extending direction of the fourth long hole is the same as the extending direction of the first long hole.

[0059] Combined with reference to Figures 1 to 5 As shown, in an embodiment of the present utility model, the fixing structure for a bicycle bracket further includes two fourth connecting members 70. Two fourth connection holes 11 are provided at the first end of the mounting structure 10. Two fifth connection holes are provided on one of the two first clamping claws 21. The two fourth connection holes 11 and the two fifth connection holes are arranged in one-to-one correspondence. The two fourth connecting members 70 are respectively passed through the correspondingly arranged fifth connection holes and fourth connection holes 11 in sequence, thereby realizing the fixed connection between the first clamping claw 21 and the mounting structure 10.

[0060] In an embodiment, the fourth connecting member 70 is a bolt.

[0061] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: An installation structure, a first clamping jaw assembly, and a second clamping jaw assembly are provided. One of the first clamping jaw assembly and the second clamping jaw assembly is clamped and fixed to the bicycle rack at the rear of the vehicle, and the other of the first clamping jaw assembly and the second clamping jaw assembly is clamped and fixed to the bicycle. When it is necessary to fix the bicycle to the bicycle rack at the rear of the vehicle, first, the second clamping jaw assembly is in a free state, and then the second clamping jaw assembly is in a second clamping state. At this time, the driving structure drives the first clamping jaw assembly to switch from the first clamping state to the first loosening state. At this time, one of the beam on the bicycle rack at the rear of the vehicle and the beam of the bicycle is clamped into the first clamping jaw assembly. Then, the second clamping jaw assembly is in a second loosening state, and the driving structure drives the first clamping jaw assembly to switch from the first loosening state to the first clamping state, realizing the clamping and fixing of the first clamping jaw assembly to one of the bicycle rack at the rear of the vehicle and the bicycle. Then, the other of the beam on the bicycle rack at the rear of the vehicle and the beam of the bicycle is clamped into the second clamping jaw assembly, and the second clamping jaw assembly is in a constrained state, realizing the clamping and fixing of the second clamping jaw assembly to the other of the bicycle and the bicycle rack at the rear of the vehicle. When it is necessary to unload the bicycle and disassemble the bicycle rack with the fixing structure, first, the second clamping jaw assembly is in a free state. At this time, the second clamping jaw assembly can freely switch between the second clamping state and the second loosening state. Then, the second clamping jaw assembly is in a second loosening state, realizing the separation of the second clamping jaw assembly from one of the bicycle and the bicycle rack at the rear of the vehicle. Then, the second clamping jaw assembly is in a second clamping state again. At this time, the driving structure drives the first clamping jaw assembly to switch from the first clamping state to the first loosening state, realizing the separation of the first clamping jaw assembly from the other of the bicycle rack at the rear of the vehicle and the bicycle, thereby realizing the disassembly of the bicycle rack with the fixing structure. As can be seen from the above, under the driving action of the driving structure, the linkage of the first clamping jaw assembly and the second clamping jaw assembly can be realized, the installation and disassembly of the fixing structure of the bicycle rack can be realized, and further the connection and disconnection between the bicycle and the bicycle rack at the rear of the vehicle can be realized. The entire installation and disassembly process does not require the use of other tools, the operation is relatively simple, and the quick installation and disassembly of the fixing structure of the bicycle rack can be realized.
