DETAILED DESCRIPTION

[0026] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments between or between technical features can be combined to form new embodiments without conflict.

[0027] In the description of the present application, it should be noted that for orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0028] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0029] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] One aspect of the present application provides a bicycle tail rack, such as Figure 1 , Figure 2 and Figure 3As shown, one preferred embodiment comprises a base 1, at least one pair of support arms 2 is installed on the base 1, and a wheel holder 3 for placing the wheel is slidingly installed on the support arm 2, and the wheel holder 3 can be slid to adapt to the corresponding size of the bicycle when the user needs to place a bicycle of different sizes. The wheel holder 3 is provided with a recess 31 for accommodating the wheel and a limiting block 32 for blocking the wheel. When the user places the wheel into the recess 31, the corresponding limiting block 32 on the two support arms 2 can limit the rolling of the wheel, avoiding the wheel from sliding in the recess 31, and further improving the installation stability of the bicycle. The base 1 is also rotatably provided with a connecting seat 4, which can be fixedly connected with the tail hook of the car.

[0031] Specifically, the number of limiting blocks 32 on each wheel holder 3 is one, and the limiting block 32 extends along the short edge direction of the recess 31; a fixing assembly 100 is also installed on the wheel holder 3, which is used to limit and fix the wheel in cooperation with the limiting block 32. The device fixes the wheel on the wheel holder 3 through two fixed points to avoid the wheel from shaking; one of the fixed points is the limiting block 32, and the other is the fixing assembly 100.

[0032] It can be understood that the wheel holder 3 of the traditional tail bicycle rack generally does not have an adjusting function. When the size of the bicycle changes, the original wheel holder 3 cannot provide more suitable support for the wheel; when the car is driving on a bumpy road, the wheel may be offset under the action of external force. The wheel holder 3 in the present application can be freely adjusted according to the specific size of the bicycle, and through the cooperation between the recess 31 and the limiting block 32, the wheel can be provided with more comprehensive protection.

[0033] In the embodiment, as shown in Figure 2 and Figure 3 , the wheel holder 3 is provided with an adjusting assembly 33 for adjusting the position of the wheel holder 3. When the size of the bicycle changes, the user can adjust the distance between the two wheel holders 3 in cooperation by changing the gear position of the adjusting assembly 33, so that the device can adapt to more sizes of bicycles, and further improve the applicability of the device.

[0034] Specifically, as shown in Figure 2 and Figure 3 , the bottom of the wheel holder 3 is provided with a sliding block 34, and the support arm 2 is provided with a sliding rail 21 that can slidingly cooperate with the sliding block 34. The user only needs to gently push the wheel holder 3 after opening the adjusting assembly 33 to drive the sliding block 34 to slide on the sliding rail 21, and then close the adjusting assembly 33 when the wheel holder 3 reaches the appropriate point to fix the wheel holder 3.

[0035] Further, as shown in Figure 3 and Figure 4As shown, the adjusting assembly 33 comprises an eccentric pin 330 and a handle 331 connected with the eccentric pin 330, the eccentric pin 330 is rotatably installed on the wheel holder 2, and a tensioning member 332 is fixedly installed on the eccentric pin 330, part of the tensioning member 332 is located inside the slide rail 21, and the size of the tensioning member 332 is greater than the width of the slide rail 21, so as to ensure that the tensioning member 330 will not be separated from the slide rail 21 during movement; the eccentric pin 330 is used to drive the tensioning member 332 to rotate and be clamped with the slide rail 21. The user can rotate the eccentric pin 330 through the handle 331 to drive the tensioning member 332 to move up and down, when the tensioning member 332 is not clamped with the slide rail 21, the wheel holder 3 is in an adjustable state, and when the tensioning member 332 is clamped with the slide rail 21, the wheel holder 21 is in a locked state.

[0036] It should be known that when the device shakes or the weight of the bicycle is too large, the position of the wheel holder 3 may be deviated, thereby affecting the connection stability between the sliding block 34 and the slide rail 21.

[0037] In view of the above situation, in some embodiments of the present application, as shown in Figure 2 and Figure 3 As shown, the two sides of the support arm 2 are provided with guide rails 22, and the wheel holder 3 is provided with guide grooves 35 for cooperating with the guide rails 22, the sliding angle of the wheel holder 3 is limited through the limiting cooperation of the guide rails 22 and the guide grooves 35, thereby ensuring that the sliding block 34 can move stably on the slide rail 21.

[0038] In the embodiment, as shown in Figure 2 The fixing assembly 100 comprises a pull belt 101 installed on one side of the wheel holder 3 and a buckle 102 installed on the other side, and the pull belt 101 and the buckle 102 can be limitedly matched. When the wheel abuts against the limiting block 32, the movable end of the pull belt 101 is inserted through the gap of the wheel and is inserted with the buckle 102. The user can change the insertion depth of the pull belt 101 and the buckle 102 according to the actual situation, thereby changing the fastening degree of the wheel. The limiting cooperation mode of the pull belt 101 and the buckle 102 includes but is not limited to that a plurality of clamping teeth are arranged on the pull belt 101, and then the buckle 102 is clamped with the clamping teeth at the corresponding position according to the required pulling of the pull belt 101.

[0039] In the embodiment, as shown in Figure 1 The connecting seat 4 is provided with an inclination plate handle 41 for controlling the rotation angle of the base 1. The user can adjust the rotation angle of the base 1 by pressing down the inclination plate handle 41, thereby making the base 1 and the vehicle present different angles, so as to avoid scratching between the bicycle on the device and the opened trunk of the car.

[0040] Further, as shown in Figure 1 and Figure 5As shown, the end of the connecting seat 4 is provided with a mounting portion 42, and a clamping assembly 5 for fixing the connecting structure between the automobile and the connecting seat 4 is mounted on the mounting portion 42. The clamping assembly 5 comprises a ball clamp 51 and a pressing rod 52 connected with the ball clamp 51. The pressing rod 52 is rotatably mounted on the mounting portion 42, and the pressing rod 52 drives the ball clamp 51 to move by rotating. When the user needs to connect the device with the automobile tail, the towing rod of the automobile tail is inserted into the mounting point of the connecting seat 4, and then the pressing rod 52 is pressed to easily drive the ball clamp 51 to press the ball head of the automobile tail, so that the connecting seat 4 is fixedly mounted on the automobile tail.

[0041] It should be noted that a threaded knob is further arranged on the ball clamp 51 to ensure that the ball clamp 51 can press the ball head.

[0042] In the embodiment, as shown in Figure 1 , the base 1 is provided with an arc-shaped mounting plate 11, and a support frame 200 is mounted in the inner arc of the mounting plate 11. The support frame 200 and the mounting plate 11 are connected by a bolt 110. In order to further improve the connection stability of the support frame 200 and the mounting plate 11, a first locking knob 111 is mounted on one end of the bolt 110 close to the support frame 200, and the first locking knob 111 is used to press the support frame 200 to tightly adhere to the mounting plate 11.

[0043] It can be understood that the mounting plate 11 is designed to be arc-shaped in the present application, which can limit the support frame 200 in the radial direction through the arc surface, so as to avoid relative rotation between the support frame 200 and the mounting plate 11. When the user needs to store the device, the support frame can be disassembled to reduce the occupied space of the device.

[0044] Further, as shown in Figure 1 and Figure 6 , in order to further improve the fixing effect of the device on the bicycle, a support rod 300 is rotatably mounted on the support frame 200. The number of the support rod 300 is not less than the number of the support arms 2, so that at least one support rod 300 can correspond to one bicycle. The support rod 300 is provided with a locking assembly 6, and the locking assembly 6 comprises a clamping plate 61 and a second locking knob 62. The second locking knob 62 is used to fix the opening angle of the clamping plate 61. When the bicycle is placed at the correct point of the wheel holder 3, the user can rotate the support rod 300 to place the girder of the bicycle in the clamping plate 61, and then tighten the second locking knob 62 to tightly adhere to the clamping plate 61, so as to ensure that the clamping plate 61 is always in the clamping state.

[0045] It can be understood that the locking assembly 6 can further improve the fixing effect of the device on the bicycle, and avoid the inclination of the body of the bicycle during the driving of the automobile.

[0046] It should be known that the installation of the tail bicycle frame will inevitably block the tail light and license plate of the car itself, and when the vehicle drives in a dark environment, it may not be possible for the rear person to accurately judge whether the front vehicle is installed with the tail bicycle frame, thereby increasing the risk of vehicle collision; in addition, if the license plate is blocked by the tail bicycle frame, it does not comply with the traffic regulations, and may cause the user to violate traffic regulations.

[0047] In order to further improve the safety of the device, in some embodiments of the present application, as shown in Figure 1 , the tail light 500 and the license plate frame 400 are installed on the side of the base 1 away from the connecting seat 4, which can further improve the safety performance of the device. The tail light 500 can be used to remind the rear person to pay attention to the distance, and the license plate frame 400 can be used to install the car license plate, so as to avoid traffic violations caused by the license plate of the vehicle being blocked.

[0048] Further, as shown in Figure 5 and Figure 6 , the anti-theft lock 600 is installed on the second locking knob 62 and the pressure rod 52, which can improve the anti-theft function of the device and reduce the risk of theft of the bicycle frame and the bicycle.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
