Depending on the installation location and structure, they are mainly divided into roof-mounted bicycle racks, rear-mounted bicycle racks, trailer-mounted bicycle racks, and trunk-mounted bicycle racks.

[0003] In the prior art, a vehicle-mounted bicycle rack often uses a single structure such as a strap to fix the main beam of the bicycle, and a single strap is used to wrap the main beam to limit the upper part of the bicycle. This not only places high demands on the quality of the strap, but also the friction between the bicycle and the strap during long-distance movement of the vehicle will affect the binding effect of the strap. Therefore, there is room for improvement. Summary of the invention

[0004] In view of this, the present application provides a frame clamp assembly for a vehicle-mounted bicycle rack, which can have a better effect of fixing the bicycle frame, so that the bicycle can not only be stably fixed on the vehicle-mounted bicycle rack with a relatively tight fixing effect, but also will not become loose due to friction.

[0005] In summary, in order to improve the stability of the connection between the beam clamp assembly for a vehicle-mounted bicycle rack and the bicycle beam, the present application proposes a beam clamp assembly for a vehicle-mounted bicycle rack.

[0006] The present application provides a beam clamp assembly for a vehicle-mounted bicycle rack using the following technical solution:

[0007] A beam clamp assembly for a vehicle-mounted bicycle rack comprises a strap seat, a switch seat and a support seat, wherein one end of the support seat is rotatably connected to the strap seat, and the other end is rotatably connected to the switch seat, the strap seat, the switch seat and the support seat together form a slot with an adjustable opening, the strap seat is provided with a strap, and the strap can be connected to the switch seat at one end away from the strap seat; the strap seat comprises a first body, the first body is rotatably connected to the support seat, the first body is provided with a first clamping surface near the slot, the first body is also provided with a first groove, and the bottom of the first groove is arranged at an angle to the first clamping surface; One end of the strap is connected to the first groove, and the strap is provided with a first tooth; the switch seat includes a second body and a switch, the second body is rotatably connected to the support seat, the second body is provided with a second clamping surface near the notch, and the second body is also provided with a second groove, and the bottom of the second groove is arranged at an angle to the second clamping surface; the switch is located in the second groove, the switch is connected to the second body, and the switch is provided with a second tooth, the second tooth can cooperate with the first tooth, and there is a spacing between the second tooth and the bottom of the second groove, and the switch can adjust the spacing.

[0008] By adopting the above technical solution, the user places the bicycle on the vehicle-mounted bicycle rack, and after fixing the wheel part of the bicycle, the beam part of the bicycle is limited by the beam clamp assembly. The beam clamp assembly can form a slot for placing the beam part through the strap seat, the switch seat and the support seat, and because the switch seat and the beam seat can rotate around the support seat, the size of the slot can be adjusted by the rotatable switch seat and the beam seat. The user puts the beam part of the bicycle into the slot, and connects the strap and the switch seat through the strap on the strap seat, so that the strap seat, the switch seat and the support seat are The seat and the strap together form a closed curve that can surround the bicycle beam, and because the length of the strap can be adjusted, the strap seat, the switch seat, the support seat and the strap can be close to and close the bicycle beam, and the fixing effect is relatively tight, and even bicycle beams of various sizes can be closed. Among them, the supporting force exerted on the bicycle beam is mainly provided by the notch formed by the strap seat, the switch seat and the support seat. Since the strap seat, the switch seat and the support seat have good rigidity, the vehicle-mounted bicycle frame has a better supporting effect on the bicycle beam. The strap is mainly responsible for closing the switch seat and The support seat enriches the universal applicability of the beam clamp assembly, so that when the bicycle is transported through the vehicle-mounted bicycle rack, the bicycle will not be affected by the friction with the strap seat and the switch seat. Although the beam clamp assembly also has a strap part, the strap accounts for a limited proportion and the impact is relatively weak. Overall, the beam clamp assembly has excellent compressive stiffness in the process of supporting the bicycle; the first clamping surface and the bottom of the first groove, the second clamping surface and the bottom of the second groove are all arranged at an angle, so that the angle that the first clamping surface and the second clamping surface can form is greater than the angle between the bottom of the first groove and The angle that can be formed by the bottom of the second groove makes the clamping range of the first clamping surface and the second clamping surface for clamping the bicycle beam larger, while the angle between the bottom of the first groove and the second groove used for the movement of the strap is smaller, so that when the first clamping surface and the second clamping surface are clamping a larger bicycle beam, the strap is more responsible for wrapping the first clamping surface and the second clamping surface, rather than providing supporting force to the bicycle beam. By reducing the load-bearing effect of the strap, not only the connection effect between the beam clamp assembly and the bicycle beam can be improved, but also the service life of the beam clamp assembly can be extended.

[0009] Preferably, the switch includes a button portion and a connecting portion, the button portion is connected to the connecting portion, two ends of the connecting portion are rotatably connected to the second groove, a torsion spring is provided on the connecting portion, and the second tooth is opened on the connecting portion.

[0010] By adopting the above technical solution, after the bicycle frame is placed between the strap seat, the switch seat and the support seat, the user can tightly limit the bicycle frame by connecting the strap and the switch seat. The specific steps of connecting the strap and the switch seat are: first, the user presses the button part, the connecting part and the second body rotate relative to each other, the spacing between the second teeth on the connecting part and the bottom of the second groove on the second body changes, and then it is easy to insert the strap into the spacing; secondly, the user inserts the strap into the spacing, wherein the side of the strap with the first teeth is arranged close to the connecting part; finally, the user puts down the button part, and the user achieves tight limitation of the bicycle frame by tightening the strap (it is also possible to first achieve tight limitation of the bicycle frame by tightening the strap and then put down the button part).

[0012] By adopting the above technical solution, since the first teeth cooperate with the second teeth and the above-mentioned connection part is set, after the strap is inserted into the spacing, the user can first put down the button part so that the strap is confined on the switch seat, and due to the design of the first teeth and the second teeth, the first teeth can slide unidirectionally in the gap between the second teeth and the bottom of the second groove, which is similar to the principle of cable ties, so that when the bicycle is transported through the vehicle-mounted bicycle rack, no matter whether the road is bumpy or not, it is difficult to cause the strap to loosen only by the friction between the bicycle frame and the strap, so that the frame clamp assembly has a better connection effect and a tighter connection.

[0013] Preferably, a first protrusion is provided at one end of the connecting portion, a third groove is formed on the first protrusion, and a pin lock is provided on the second body, and the pin lock can cooperate with the third groove.

[0028] 1. The user places the bicycle on the vehicle-mounted bicycle rack, and after fixing the wheel part of the bicycle, the beam part of the bicycle is limited by the beam clamp assembly. The beam clamp assembly can form a slot for placing the beam part through the strap seat, the switch seat and the support seat, and because the switch seat and the beam seat can rotate around the support seat, the size of the slot can be adjusted by the rotatable switch seat and the beam seat. The user puts the beam part of the bicycle into the slot, and connects the strap and the switch seat through the strap on the strap seat, so that the strap seat, the switch seat, the support seat and the strap together form a closed curve that can surround the bicycle beam, and because the length of the strap can be adjusted, the strap seat, the switch seat, the support seat and the strap can be close to and close the bicycle beam, fixing The fixing effect is relatively tight, and even bicycle beams of various sizes can be closed.

By reducing the load-bearing effect of the strap 4, not only the connection effect between the beam clamp assembly and the bicycle beam can be improved, but also the service life of the beam clamp assembly can be extended.

The tooth groove 30 and the tooth protrusion 26 are arranged in a centrally symmetrical manner, so that the tooth groove 30 and the tooth protrusion 26 together form a second tooth 18.

[0053] Since the first teeth 12 cooperate with the second teeth 18 and the above-mentioned connection portion 20 is arranged, after the strap 4 is inserted into the gap, the user can first put down the button portion 19 so that the strap 4 is confined on the switch seat 2, and due to the design of the first teeth 12 and the second teeth 18, the first teeth 12 can slide unidirectionally in the gap between the second teeth 18 and the bottom of the second groove 17, similar to the principle of a cable tie, so that when the bicycle is transported through the vehicle-mounted bicycle rack, regardless of whether the road is bumpy or not, it is difficult to cause the strap 4 to loosen only through the friction between the bicycle beam and the strap 4, so that the beam clamp assembly has a better connection effect and a tighter connection.

[0054] Furthermore, in the present embodiment, a first protrusion 31 is integrally formed at the right end of the connecting portion 20, a third groove 32 is formed on the first protrusion 31, and a pin lock 33 is screwed to the second body 13, so that when the distance between the second tooth 18 on the connecting portion 20 and the bottom of the second groove 17 is the smallest, the pin lock 33 can be inserted into the third groove 32 of the connecting portion 20, thereby ensuring the stability of the bicycle frame limit jointly by the strap 4, the strap seat 1, the switch seat 2 and the support seat 3.

[0055] Furthermore, in the present embodiment, the first body 8 is provided with an arc corner 44 at the connection between the bottom of the first groove 11 and the first clamping surface 10; and the second body 13 is also provided with an arc corner 44 at the connection between the bottom of the second groove 17 and the second clamping surface 16. By setting the arc corner 44, when the two ends of the strap 4 are respectively connected to the strap seat 1 and the switch seat 2, the strap 4 can not only fit the strap seat 1 and the switch seat 2 to the greatest extent, but also the arc connection corner is very conducive to the fitting of the strap 4, so that the beam clamp assembly can maximize the supporting effect of the strap seat 1 and the switch seat 2, and reduce the proportion of the strap 4 in the limited bicycle beam when the beam clamp assembly is connected to the bicycle beam.

[0056] Furthermore, in the present embodiment, a clamping groove 34 is provided on the first clamping surface 10 of the first body 8, and a soft pad 35 is glued into the clamping groove 34; a clamping groove 34 is also provided on the second clamping surface 16 of the second body 13, and a soft pad 35 is glued into the clamping groove 34; striped protrusions are provided on the soft pads 35 of the first body 8 and the second body 13, and a soft pad 35 is also glued to the left end of the support seat 3, and friction lines are provided on the soft pad 35 of the support seat 3. The soft pad 35 prevents the frame clamp assembly from scratching the paint of the bicycle frame, etc., which is beneficial to ensure the integrity of the bicycle to be transported.

[0057] Furthermore, in this embodiment, the width of the strap 4 at the end away from the strap seat 1 is smaller than the width of the strap 4 at the end close to the strap seat 1. The smaller width of the strap 4 at the end away from the strap seat 1 makes it easier for the strap 4 to pass through the switch seat 2.

[0058] Furthermore, in the present embodiment, a hole 36 is provided at one end of the strap 4 away from the strap seat 1, and the inner diameter of the hole 36 is larger than the outer diameter of half an adult's finger. The hole 36 on the strap 4 is convenient for the user's fingers to pass through, and it is easier to pull the strap 4 by passing the user's fingers through the hole 36 of the strap 4 than by pinching the strap 4.

[0059] Furthermore, in the present embodiment, the beam clamp assembly further comprises a support leg 41 and a connecting nail 42, the support leg 41 comprises a leg portion and a cover portion, the cover portion is inserted into the upper side of the leg portion, one end of the connecting nail 42 is inserted into the support seat 3, and the other end is inserted into the cover portion, one side of the upper portion of the leg and the other side of the upper portion of the leg in sequence, the end of the connecting nail 42 away from the support seat 3 is located in the cover portion, and the connecting nail 42 is threadedly connected with a nut at the end away from the support seat 3; the support seat 3 is provided with a circular groove at one end close to the support leg 41, the cover portion of the support leg 41 is also provided with a circular groove at one end close to the support seat 3, the connecting nail 42 is also located at the two circular grooves, a sleeve 43 is sleeved on the connecting nail 42, and the two ends of the sleeve 43 are respectively matched with the two circular grooves, so that the support seat 3 and the support leg 41 can not only adjust the position by relative rotation of the connecting nail 42, but also adjust the distance between the support leg 41 and the support seat 3 by the sleeve 43, thereby changing the clamping angle and clamping position of the beam clamp assembly and the bicycle beam.

[0060] Furthermore, in this embodiment, the leg portion of the support leg 41 is retractable, and the specific retractable method adopts the common retractable structure of the support leg 41 in the prior art, and the specific structure is not described here. (The common support leg includes a leg portion, and the leg includes an inner leg and an outer leg. The lower end of the outer leg is provided with a countersunk hole, and the inner end of the countersunk hole is hinged with an oil cylinder, and the other end of the oil cylinder is connected to the inner leg.)

[0061] Furthermore, in this embodiment, the switch 15 and the second body 13 may be connected by sliding connection in addition to rotation. It is only necessary to make the second tooth 18 away from the bottom of the second groove 17 so that the strap 4 can pass through the second groove 17 of the second body 13.
