[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Vehicle-mounted bicycle towing systems fall under the automotive application field, used to address the need for vehicles to tow disabled electric bicycles, motorcycles, etc., on the road. Current vehicle designs lack the option to add a towing system to the rear of the vehicle for electric bicycles and motorcycles. Existing towing systems in this technology are typically complex in structure, occupy a large amount of space, and are inconvenient for overall vehicle layout.

[0032] The following is for reference. Figures 1-3 A drag-and-drop component according to an embodiment of the present invention is described.

[0033] The towing assembly 1 according to the present invention includes a base 11, a wheel fixing bracket 12, and an extension bracket 13. The base 11 is connected to the vehicle body. The wheel fixing bracket 12 is rotatably disposed at the bottom of the base 11 so that the position of the wheel fixing bracket 12 relative to the vehicle body can be selectively adjusted. The extension bracket 13 is rotatably connected to the wheel fixing bracket 12 so that it can be selectively folded with the wheel fixing bracket 12. The wheel fixing bracket 12 and the extension bracket 13 together define a receiving space 101 for accommodating the wheel to be towed.

[0034] The towing assembly 1 according to the present invention is provided with a base 11, which is fixed to the vehicle body and supports the entire towing assembly 1. Mounting holes are provided on the base 11 for connection to the vehicle body via bolts or other fasteners; alternatively, the base 11 can be directly welded to the vehicle body to ensure the stability of the connection between the towing assembly 1 and the vehicle body. In actual assembly, the base 11 can extend in the height direction of the vehicle body. A wheel fixing bracket 12 is rotatably provided at the bottom of the base 11. The wheel fixing bracket 12 can rotate relative to the bottom of the base 11 in a plane perpendicular to the extension direction of the base 11, or simply understood as the wheel fixing bracket rotating in a horizontal plane. An extension bracket 13 is rotatably provided on the wheel fixing bracket. It should be noted that the rotation direction of the extension bracket 13 is not in the same plane as the rotation direction of the wheel fixing bracket 12. The extension bracket 13 can be understood as rotating in the plane containing the extension direction of the base 11. The rotation of the extension bracket 13 allows the extension bracket 13 and the wheel fixing bracket 12 to fold together. The extension bracket 13 and the wheel fixing bracket 12 define a space 101 for accommodating the wheel to be towed (i.e., the wheel of the disabled vehicle). When the towing assembly 1 is needed, the wheel fixing bracket 12 can be rotated to an angle perpendicular to the vehicle, i.e., the wheel fixing bracket 12 is perpendicular to the vehicle body and extends towards the rear of the vehicle. Then, the extension bracket 13 is opened, and the wheel of the disabled vehicle to be towed is placed in the space 101 defined by the extension bracket 13 and the wheel fixing bracket 12. The wheel is then fixed to the vehicle by the extension bracket 13 and the vehicle fixing bracket to facilitate towing the disabled vehicle. The wheel fixing bracket 12 is designed so that the entire towing assembly 1 can be hidden under the rescue vehicle by rotation after being assembled on the rescue vehicle. When needed, the wheel fixing bracket 12 can be rotated to the preset towing position, which is simple and easy to operate. The rotatable extension bracket 13 relative to the wheel fixing bracket 12 enables the towing assembly 1 to be folded, which can reduce the space occupied by the towing assembly 1 and facilitate the arrangement of the towing assembly 1.

[0035] According to one embodiment of the present invention, the wheel mounting bracket 12 includes: a first pivot portion 121 and a mounting bracket body 122, the first pivot portion 121 being rotatably disposed at the bottom of the base 11 and extending in a first direction; the mounting bracket body 122 being rotatably connected to the first pivot portion 121 and extending in a direction away from the first pivot portion 121; wherein, the first pivot portion 121 is adapted to rotate in the first direction to adjust the position of the mounting bracket body 122 relative to the vehicle body.

[0036] The wheel mounting bracket 12 is provided with a first pivot part 121 and a mounting bracket body 122. The first pivot part 121 is rotatably connected to the base 11. The first pivot part 121 is located at the bottom of the base 11 and extends in a first direction, which can be simply understood as the height direction of the vehicle body. The first pivot part 121 can be simply understood as a pivot shaft rotatably connected to the base 11. The mounting bracket body 122 is provided on the first pivot part 121. The mounting bracket body 122 can cooperate with the extension bracket 13 and jointly define the accommodating space 101 to accommodate the wheel to be towed. When the towing assembly 1 is needed, the fixing frame body 122 can be rotated to a preset position by rotating the first pivot 121 (the preset position is the position where the wheel fixing frame 12 is perpendicular to the vehicle body and extends towards the rear of the vehicle body in the above embodiment). Then, the fixing frame body 122 is engaged with the wheel to be towed to complete the towing task. After the towing task is completed, the fixing frame body 122 can be rotated to the bottom of the vehicle body and hidden by rotating the first pivot 121, making the entire towing assembly 1 more compact, occupying less space, and easy to carry and store. At the same time, it can also prevent the towing assembly 1 from being exposed and affecting the aesthetics and safety of the vehicle.

[0037] Furthermore, the fixed frame body 122 and the first pivot part 121 are also rotatably connected. It should be noted that the rotation direction of the fixed frame body 122 is different from that of the first pivot part 121. The first pivot part 121 can be understood as rotating in a first direction with itself as the axis, while the fixed frame body 122 rotates in a plane parallel to the first direction. That is, the fixed frame body 122 can adjust its height relative to the ground by rotating, so as to adapt to different vehicle models and improve the flexibility of the towing assembly 1.

[0038] According to one embodiment of the present invention, a first locking part 123 is provided on the wheel fixing bracket 12, which selectively restricts the rotation of the first pivoting part 121. The first locking part 123 can restrict the rotation of the first pivoting part 121. For example, when the towing assembly 1 is needed, the first locking part 123 is unlocked to release the restriction on the first pivoting part 121, so that the first pivoting part 121 can rotate to adjust the direction of the towing assembly 1; when the towing assembly 1 is not needed, the first locking part 123 can be locked after the first pivoting part 121 returns to its initial position, restricting the rotation of the first pivoting part 121. This can prevent the first pivoting part 121 from rotating due to vehicle vibration during vehicle operation, thereby improving vehicle safety.

[0039] According to an embodiment of the present invention, the towing assembly 1 further includes a limiting member 124, which is disposed on the base 11 or the wheel fixing frame 12. The limiting member 124 is adapted to restrict the rotation of the fixing frame body 122 and the first pivoting part 121 when the first pivoting part 121 drives the fixing frame body 122 to rotate to a predetermined position. When the towing assembly 1 is working, the wheel fixing frame 12 needs to rotate to a direction perpendicular to the vehicle body and extending towards the rear of the vehicle body. Therefore, the towing assembly 1 can be provided with the limiting member 124 on the wheel fixing frame 12. When the first pivoting part 121 drives the fixing frame body 122 to rotate to the preset position, the limiting member 124 can restrict the rotation of the first pivoting part 121, avoiding the first pivoting part 121 from rotating too much and causing the wheel fixing frame 12 to exceed the preset position and deflect. This can ensure that the disabled vehicle remains directly behind the rescue vehicle when the towing assembly 1 tows the disabled vehicle, improving the stability and safety of the towing assembly 1 when towing the disabled vehicle.

[0040] According to one embodiment of the present invention, the fixing frame body 122 includes a first bracket 1221 and a second bracket 1222. The first bracket 1221 and the second bracket 1222 are respectively connected to a first pivot portion 121 and gradually move away from each other in the extending direction of the fixing frame body 122 to define at least a portion of the receiving space 101. Since the fixing frame body 122 is a structure for fixing a disabled wheel, the construction of the fixing frame body 122 affects the towing assembly 1's ability to tow a disabled wheel. Specifically, the fixing frame body 122 defines a portion of the receiving space 101 by the first bracket 1221 and the second bracket 1222 gradually moving away from each other in the extending direction of the fixing frame body 122. This receiving space 101 is specifically designed for the wheel of the vehicle to be towed. When the wheel to be towed is received into the receiving space 101, the first bracket 1221 and the second bracket 1222 can limit the wheel to be towed on both sides to ensure that the wheel to be towed is stably fixed and contained during towing, avoiding shaking or falling off the wheel during towing.

[0041] According to one embodiment of the present invention, the dragging assembly 1 further includes: a first connecting rib 141 and a second connecting rib 142, one end of the first connecting rib 141 and one end of the second connecting rib 142 being connected to the base 11, and the other end of the first connecting rib 141 and the other end of the second connecting rib 142 being connected to the first bracket 1221 and the second bracket 1222, respectively. Figures 1-3As shown, after the first pivot 121 drives the fixed frame body 122 to rotate to a preset position, a first connecting rib 141 and a second connecting rib 142 can be provided between the fixed frame body 122 and the base 11. The first connecting rib 141 connects the first bracket 1221 to the base 11; the second connecting rib 142 connects the second bracket 1222 to the base 11. The provision of the first connecting rib 141 and the second connecting rib 142 can generate a certain pulling force on the fixed frame body 122 from the base 11, which can improve the stability of the fixed frame body 122 during the dragging process, prevent the fixed frame body 122 from being compressed and collapsed, and improve the safety of the dragging assembly 1.

[0042] In some embodiments, the first connecting rib 141 and the second connecting rib 142 may be steel wires.

[0043] According to one embodiment of the present invention, a second pivot portion 151 and a third pivot portion 152 are respectively provided on the first support 1221 and the second support 1222. The extension support 13 includes a third support 131, a fourth support 132 and a limiting support 133. The third support 131 is rotatably disposed on the second pivot portion 151; the fourth support 132 is rotatably disposed on the third pivot portion 152; the limiting support 133 is connected to the third support 131 and the fourth support 132 respectively; wherein the third support 131 and the fourth support 132 are spaced apart from each other to define at least another part of the receiving space 101, and the limiting support 133 is adapted to close the opening of the receiving space 101.

[0044] The extension bracket 13 and the wheel fixing bracket 12 are rotatably connected. Specifically, the first bracket 1221 and the second bracket 1222 are respectively provided with a second pivot portion 151 and a third pivot portion 152, and the extension bracket 13 is provided with a third bracket 131 and a fourth bracket 132, wherein: the third bracket 131 is rotatably disposed on the second pivot portion 151; and the fourth bracket 132 is rotatably disposed on the third pivot portion 152. The dragging assembly 1 realizes the rotatable connection between the third bracket 131 and the first bracket 1221 and the rotatable connection between the fourth bracket 132 and the second bracket 1222 through the second pivot portion 151 and the third pivot portion 152, thereby allowing the entire extension bracket 13 to rotate relative to the wheel fixing bracket 12, so as to realize the folding of the extension bracket 13 and the wheel fixing bracket 12. When the third bracket 131 and the fourth bracket 132 are connected to the second pivot 151 and the third pivot 152 respectively, the third bracket 131 and the fourth bracket 132 form another receiving space 101. An opening is formed between the free end of the third bracket 131 and the free end of the fourth bracket 132. When the towing assembly 1 is assembled with a wheel to be towed, the wheel to be towed can enter the receiving space 101 through the opening between the third bracket 131 and the fourth bracket 132, which can improve assembly efficiency.

[0045] In addition, the extension bracket 13 is also provided with a limiting bracket 133. The limiting bracket 133 is located at the opening formed by the third bracket 131 and the fourth bracket 132. That is, one end of the limiting bracket 133 is connected to the third bracket 131, and the other end of the limiting bracket 133 is connected to the fourth bracket 132. When the wheel to be towed enters the receiving space 101, the limiting bracket 133 can close the opening formed by the third bracket 131 and the fourth bracket 132 and limit the wheel to be towed, preventing the wheel to be towed from coming out of the receiving space 101 and improving the stability of the towing process.

[0046] According to one embodiment of the present invention, one of the third bracket 131 and the fourth bracket 132 is provided with a fourth pivot portion 1311, and the limiting bracket 133 is adapted to rotate around the fourth pivot portion 1311 to open or close the receiving space 101; the other of the third bracket 131 and the fourth bracket 132 is provided with a second locking portion 1321, and the second locking portion 1321 is adapted to restrict the rotation of the limiting bracket 133.

[0047] The towing assembly 1 is provided with a fourth pivot 1311 and a second locking part 1321 on the third bracket 131 and the fourth bracket 132, respectively. One end of the limiting bracket 133 is rotatably connected to the fourth pivot 1311, and the other end of the limiting bracket 133 can cooperate with the second locking part 1321. When a wheel to be towed needs to be assembled, the second locking part 1321 unlocks, and the limiting bracket 133 rotates about the fourth pivot 1311 as an axis, opening the opening formed by the third bracket 131 and the fourth bracket 132. After the wheel to be towed is assembled into the receiving space 101, the limiting bracket 133 rotates back to close the opening, and the second locking part 1321 locks to ensure the stability of the limiting bracket 133. The setting of the second locking part 1321 and the fourth pivot 1311 can prevent interference when the limiting bracket 133 is assembled with the wheel to be towed, and can also improve the stability of the limiting bracket 133 after assembly. The whole process is simple, convenient and easy to operate.

[0048] According to one embodiment of the present invention, a plurality of positioning holes 125 spaced apart from each other are respectively provided on the first bracket 1221 and the second bracket 1222, the second pivot portion 151 and the third pivot portion 152 are respectively configured as positioning pins provided in the corresponding positioning holes 125, and the third bracket 131 and the fourth bracket 132 are respectively rotatably connected to the corresponding positioning pins.

[0049] The second pivot 151 and the third pivot 152 are respectively configured as positioning pins on the first bracket 1221 and the second bracket 1222. Specifically, the dragging assembly 1 is provided with a plurality of positioning holes 125 on the first bracket 1221 and the second bracket 1222 respectively. The third bracket 131 can be rotatably connected to the first bracket 1221 by cooperating with a positioning hole 125 on the first bracket 1221 through a corresponding positioning pin. Similarly, the fourth bracket 132 can be rotatably connected to the second bracket 1222 by cooperating with a positioning hole 125 on the second bracket 1222 through a corresponding positioning pin. When the towing assembly 1 is in use, if the size of the wheel to be towed does not match the size of the accommodating space 101, the position of the positioning pin on the first bracket 1221 and the second bracket 1222 can be changed so that the positioning pin engages with other positioning holes 125, thereby adjusting the size of the accommodating space 101 formed by the fixed frame body 122 and the extension bracket 13, so as to adapt to wheels of different sizes and improve the flexibility of the towing assembly 1.

[0050] It should be noted that the preset position in this invention refers to the position when the towing component 1 is in use, at which time the wheel fixing bracket 12 of the towing component 1 is perpendicular to the width direction of the vehicle body; the initial position refers to the position when the towing component 1 is hidden under the vehicle body, at which time the wheel fixing bracket 12 is parallel to the width direction of the vehicle body.

[0051] In some embodiments, the towing assembly 1 is further provided with a signal device 102, which is rotatably mounted on the fixed frame body 122. The signal device 102 can detect the driving status of the rescue vehicle (i.e., the vehicle equipped with the towing assembly 1) in real time and display it to other surrounding vehicles through signal lights or other means, so that other vehicles can understand the status of the rescue vehicle. When the towing assembly 1 is in use, the signal device 102 can be rotated to be perpendicular to the ground so that the drivers and passengers of surrounding vehicles can observe it.
