DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0025] See also Figure 1 , which is a structural diagram of a bicycle rack provided by the utility model. Figures 1 to 6 The bicycle rack for a vehicle includes, for example, a base 10, a support frame 20, and a latch structure 30. The support frame 20 is rotatably disposed above the base 10, and the latch structure 30 is disposed between the base 10 and the support frame 20 for locking or unlocking the support frame 20.

[0026] For example, combining Figure 1 and Figure 5The vehicle bicycle rack can be installed at the rear of the car through the support frame 20 to carry and transport the bicycle; it can also be installed on the crossbeam of a trailer caravan through the fixing hoop under the base 10 to carry and transport the bicycle.

[0027] It is understood that, compared to using a bolt structure as the connection structure between the base 10 and the support frame 20, the use of the latch structure 30 as the connection structure between the base 10 and the support frame 20 allows the support frame 20 to be locked or unlocked by simply inserting or removing the fixing pin 31 of the latch structure 30, thereby expanding or folding the support frame 20. There is no need to rotate the bolt multiple times to loosen it, making operation simple and quick. The latch structure 30 can improve the convenience of use of the bicycle rack while ensuring the stability of the connection between the base 10 and the support frame 20.

[0028] Further, combined Figure 3 and Figure 4 The latch structure 30 includes, for example, a fixing pin 31 and a fixing support seat 32. The fixing support seat 32 is disposed on the base 10, and a support receiving groove 321 for mounting the support frame 20 is provided on one side of the fixing support seat 32 close to the support frame 20.

[0029] In one specific embodiment, a first insertion hole 322 is provided on the side wall of the support receiving groove 321, and a corresponding second insertion hole is provided on the support frame 20. When the support frame 20 and the base 10 need to be locked, the support frame 20 is first rotated into the support receiving groove 321 of the fixed support seat 32. At this time, the first insertion hole 322 is aligned with the second insertion hole. Then, the fixing pin 31 is inserted into the first insertion hole 322 on the side wall of the support receiving groove 321. The fixing pin 31 passes through the side wall of the support receiving groove 321 on one side and the support frame 20 located in the support receiving groove 321, and then passes through the side wall of the support receiving groove 321 on the other side, thereby locking the support frame 20 in the support receiving groove 321. When the support frame 20 and the base 10 need to be unlocked, the fixing pin 31 is simply pulled out from the first insertion hole 322 and the second insertion hole to release the locking of the support frame 20 and the base 10 by the fixing pin 31.

[0030] Furthermore, the latch structure 30 includes a flexible connector 33. One end of the flexible connector 33 is connected to the fixing pin 31, and the other end is connected to the base 10 or support frame 20. For example, when the fixing pin 31 is removed from the first insertion hole 322 and the second insertion hole, the flexible connector 33 can connect the removed fixing pin 31 to the base 10 or support frame 20, thereby preventing the removed fixing pin 31 from being lost. For example, the flexible connector 33 can be a flexible anti-lost rope.

[0031] Furthermore, the latch structure 30 includes a reinforcement structure 34 disposed on the sidewall of the support receiving slot 321. For example, the reinforcement structure 34 is disposed on the sidewall outside the fixed support base 32 and is located around the first insertion hole 322. In one specific embodiment, the reinforcement structure 34 includes a reinforcement boss disposed along the axial direction of the first insertion hole 322 and a reinforcement rib connected between the reinforcement boss and the outer wall of the fixed support base 32.

[0032] It is understood that since the fixed support seat 32 has a support receiving groove 321 for receiving the support frame 20 on the side thereof close to the support frame 20, and a first insertion hole 322 that cooperates with the fixing pin 31 is formed on the side wall of the support receiving groove 321, in order to ensure the strength of the fixed support seat 32 and prevent deformation of the fixed support seat 32, which would affect the locking effect of the fixed support seat 32 on the support frame 20, a reinforcement structure 34 is provided on the side wall of the support receiving groove 321. Furthermore, in order to prevent deformation of the first insertion hole 322, the reinforcement structure 34 is provided around the first insertion hole 322. This can improve the strength of the side wall of the fixed support seat 32 and prevent deformation of the first insertion hole 322 during the insertion and removal of the fixing pin 31.

[0033] Furthermore, the bicycle frame, for example, also includes a first clamping portion 40 and a second fixing portion 50. The first clamping portion 40 is provided on the support frame 20 for clamping the body of the bicycle; the second fixing portion 50 is provided on the support frame 20 or the base 10 for fixing the tire of the bicycle. For example, the first clamping portion 40 is a clamp movably mounted on the support frame 20, and the second fixing portion 50 is a U-shaped or trumpet-shaped fixing seat provided on the support frame 20 or the base 10. Preferably, a fixing strap is provided on the U-shaped or trumpet-shaped fixing seat, and an anti-slip strip is provided on the inner wall of the U-shaped or trumpet-shaped fixing seat. The number of the first clamping portion 40 and the second fixing portion 50 can be set according to the bicycle loading capacity of the bicycle frame, and is not limited here.

[0034] Furthermore, the bicycle rack for a vehicle further includes, for example, an articulated mounting member 60. The articulated mounting member 60 is fixedly connected to the base 10 and extends toward the support frame 20. Specifically, the support frame 20 is rotatably disposed above the base 10 via the articulated mounting member 60.

[0035] Preferably, the articulated mounting member 60 includes an articulated protruding plate 61 connected to both sides of the base 10 and a connecting plate 62 located below the base 10. The connecting plate 62 connects the two articulated protruding plates 61 to form an articulated mounting member 60 with a U-shaped structure. Specifically, both side walls of the articulated mounting member 60 with a U-shaped structure are provided with articulated holes. For example, the articulated protruding plate 61 and the connecting plate 62 can be welded together or can be an integrally formed structure; the articulated hole can be provided on the articulated protruding plate 61, can be provided on the connecting plate 62, or can be provided at the connection between the articulated protruding plate 61 and the connecting plate 62, and there is no limitation here.

[0036] It can be understood that, compared with directly setting the hinged protruding plates 61 on both sides of the base 10, setting the hinged mounting member 60 into a U-shaped structure can provide a supporting force to the bottom of the base 10 through the connecting plate 62 located below the base 10, thereby making the connection between the hinged mounting member 60 and the base 10 more secure and improving the connection stability between the base 10 and the support frame 20.

[0037] In a specific embodiment, combining Figure 1 and Figure 2 , the bicycle rack is mounted to the rear of the car through the support frame 20, and the base 10 is flippable; the support frame 20 includes a vertical frame 21 and a bottom frame 22, and the vertical frame 21 and the bottom frame 22 are connected in an arc to form an L-shaped support frame, and the second fixing portion 50 is arranged on the bottom frame 22. Among them, the hinged mounting member 60 is hinged to the arc connecting section of the L-shaped support frame, and the latch structure 30 is used to lock or unlock the bottom frame 22. For example, the arc connecting section of the L-shaped support frame is clamped between two hinged protruding plates 61, and the support frame 20 is rotatably arranged between the two hinged protruding plates 61 through a hinge shaft. When the L-shaped support frame is rotated to the specified position, the bottom frame 22 is located in the support accommodating groove 321, and the fixing pin 31 passes through the fixed support seat 32 and the bottom frame 22 to lock the L-shaped support frame.

[0038] Preferably, the angle formed between the hinged mounting member 60 and the base 10 is an acute angle, so that when the latch structure 30 locks the base 10 and the support frame 20, a stable triangular structure is formed between the base 10, the hinged mounting member 60 and the L-shaped support frame, thereby further improving the connection stability between the base 10 and the support frame 20.

[0039] In a specific embodiment, combining Figure 5 and Figure 6 The bicycle rack is installed on the crossbeam of the trailer caravan through the fixing hoop below the base 10 , the support frame 20 is flippable, and the second fixing part 50 is set on the base 10 .
