Description

Technical Field

[0001] This utility model relates to the field of bicycle frame technology, specifically a novel bicycle frame. Background Technology

[0002] A bicycle rack is a support frame that can be installed in front of a car to position and hold a bicycle.

[0003] Publication numbers CN219096603U and CN217917786U both describe a bicycle frame. While it can support the bicycle at the front of the bike to some extent, its support components are relatively fixed. This means that when not in use, it occupies the same space as when in use, affecting its convenience when used with the vehicle. Furthermore, its support method is too simplistic, relying solely on a connecting beam. When the bicycle is placed on it, the continuous movement of the vehicle can cause it to be subjected to excessive stress, leading to breakage and compromising its safety.

[0004] Therefore, a new type of bicycle frame is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel bicycle frame that solves the problems of low support strength and incompatibility when folded in front of the bicycle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support beam comprising an I-beam support beam, an auxiliary support beam, a front connecting beam, and a rotating beam;

[0007] The I-beam support beam is rotatably connected to the front connecting beam, and the auxiliary support beam is rotatably connected to the rotating beam;

[0008] The supporting auxiliary beam has two sets of tire placement racks distributed in an alternating manner on both sides, and the tire placement racks are slidably connected to the supporting auxiliary beam;

[0009] At least two vehicle body limiting frames that are staggered are slidably installed on the outer side of the rotating beam;

[0010] The front connecting beam is installed on the outside of the vehicle via the vehicle connecting beam.

[0011] Preferably, the tire placement rack and the vehicle body limiting rack located on the same side operate as a group, and the two vehicle body limiting racks are located at different heights, and the two tire placement racks located at the same end of the supporting auxiliary beam are staggered.

[0012] Preferably, a support column is fixedly connected to the inner end of the tire placement rack, and a fastening band assembly for fastening the support is provided on the tire placement rack. A sliding shell is sleeved and connected to the outer side of the support auxiliary beam. One end of the support column is inserted into the outer side of the sliding shell. Fastening bolts are inserted into both the sliding shell and one end of the support column. A handle is threaded onto the upper end of the fastening bolt.

[0013] Preferably, the sliding housing is simultaneously fitted onto the outside of the rotating beam, and one end of the vehicle body limiting bracket is inserted into the outside of the sliding housing. The sliding housing and the handle are fastened and limited by the handle and the fastening bolt.

[0014] Preferably, a support frame is fixedly sleeved in the middle of the support auxiliary beam. At least two positioning holes are opened through one side of the support frame on both sides, and the two positioning holes are inclinedly distributed. A groove corresponding to the positioning hole is provided through the rotating beam. A hole for inserting a positioning bolt is provided below the positioning hole. A plug is connected through the positioning hole and the rotating beam. A limiting band for positioning support is sleeved on the plug.

[0015] Preferably, at least two plug-in pieces are fixedly connected to the side of the I-beam support beam, and at least two support frames are fixedly connected to one side of the front connecting beam, with the plug-in pieces inserted into the interior of the support frames.

[0016] Preferably, the positioning bolt and the plug are provided through the inside of the second support frame and the plug piece, and slots for the positioning bolt and the plug are provided on both sides of the second support frame and the plug piece.

[0017] Compared with the prior art, the present invention provides a novel bicycle frame with the following advantages:

[0018] 1. This new type of bicycle frame, through the cross arrangement of I-beam support beams, auxiliary support beams, and headstock connecting beams, as well as the matching folding structure installed at the front of the bicycle, can improve the ease of folding while ensuring the stable support strength of the device when installed at the front of the bicycle.

[0019] 2. When the new bicycle frame is in use, the I-shaped support beam and rotating beam are unfolded, and then the positions of the tire placement frame and the frame limiting frame are adjusted so that the device can be used in an unfolded state. It can also provide adaptive support for two bicycles separately, increasing the placement space in front of the vehicle.

[0020] 3. When the new bicycle frame is not in use, the I-beam support beam and rotating beam are folded, and the tire rack and body limiting rack are moved to the center, so that the whole device is folded, reducing its space occupation and making it more convenient to place it in front of the bicycle when not in use.

[0021] 4. When the new bicycle frame needs to be folded, moved, or placed, first disconnect the connection between the front connecting beam and the vehicle connecting beam, then remove the plug and the limiting band. At this time, the positioning bolt acts as a rotating support part, and the front connecting beam is flipped upward so that its upper surface gradually fits with the upper surface of the I-beam support beam, forming a folding and storage effect on the front connecting beam and the I-beam support beam, further reducing the space occupied when it is placed.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Please see Figure 1 - Figure 6The novel bicycle frame in this embodiment includes a support beam, which is composed of an I-shaped support beam 1, a support auxiliary beam 101, a front connecting beam 102, and a rotating beam 103.

[0032] The I-beam support beam 1 is rotatably connected to the head connecting beam 102, and the auxiliary support beam 101 is rotatably connected to the rotating beam 103;

[0033] Two sets of tire placement racks 2 are staggered on both sides of the supporting auxiliary beam 101, and the tire placement racks 2 are slidably connected to the supporting auxiliary beam 101.

[0034] At least two vehicle body limit brackets 201 are slidably mounted on the outer side of the rotating beam 103 in a staggered manner;

[0035] The front connecting beam 102 is installed on the outside of the vehicle via the vehicle connecting beam 7;

[0036] Specifically, by setting the connection between the rotating beam 103 and the supporting auxiliary beam 101 to be rotating, the rotating beam 103 and the supporting auxiliary beam 101 can be folded or unfolded for use. By setting the connection between the I-shaped support beam 1 and the front connecting beam 102 to be rotating, the front connecting beam 102 and the I-shaped support beam 1 can be folded or unfolded for use. In addition, under the sliding combination of the tire placement frame 2 and the supporting auxiliary beam 101, when the device is in use, the I-shaped support beam 1 and the rotating beam 103 are unfolded, and then the positions of the tire placement frame 2 and the body limiting frame 201 are adjusted so that the device is used in an unfolded state, and can be used to adaptively place and support two bicycles separately. When the device is not in use, the I-shaped support beam 1 and the rotating beam 103 are folded, and the tire placement frame 2 and the body limiting frame 201 are moved to the center so that the device as a whole is in a folded state, reducing its space occupation and making it more reasonable to place when not in use.

[0037] By using the cross arrangement of I-beam support beam 1, auxiliary support beam 101, and front connecting beam 102, as well as the matching folding structure installed at the front of the vehicle, the device can be made more convenient to fold while ensuring stable support strength.

[0038] The front connecting beam 102 is connected and fixed to the vehicle connecting beam 7 by using bolts or other fastening methods to ensure the stability and reliability of the overall connection between the device and the vehicle.

[0039] The tire placement rack 2 and the vehicle body limiting rack 201 located on the same side operate as a group, and the two vehicle body limiting racks 201 are located at different heights. The two tire placement racks 2 located at the same end of the supporting auxiliary beam 101 are staggered.

[0040] The inner end of the tire placement rack 2 is fixedly connected to a support column 4. The tire placement rack 2 is provided with a fastening belt group 3 for fastening the support. The outer side of the support auxiliary beam 101 is fitted with a sliding shell 5. One end of the support column 4 is inserted into the outer side of the sliding shell 5. The sliding shell 5 and one end of the support column 4 are simultaneously inserted with a fastening bolt 502. The upper end of the fastening bolt 502 is threaded with a handle 501.

[0041] The sliding housing 5 is simultaneously fitted onto the outside of the rotating beam 103, and one end of the vehicle body limiting bracket 201 is inserted into the outside of the sliding housing 5. The sliding housing 5 and the handle 501 are fastened and limited by the handle 501 and the fastening bolt 502.

[0042] By adjusting the flexible toothed part inside the fastening band group 3, it is inserted and positioned with the limiting part on one side to achieve the limiting effect. Since the limiting method of this part is existing technology, it is not shown in detail in the attached figure.

[0043] By turning the handle 501, the fastening of the sliding shell 5 and the support column 4 is released. Then, the tire mounting bracket 2 is pushed, causing the support column 4 to slide the sliding shell 5 on the support beam 101. After sliding to a position that is compatible with the size of the bicycle, the handle 501 is turned again, causing the fastening bolt 502 to move upward, thereby squeezing the sliding shell 5 and the support column 4 and causing them to deform. This results in a tight and limited position at the contact point between the sliding shell 5 and the support beam 101. Then, the fastening belt group 3 is adjusted to position the wheel, ultimately achieving an adjustable limit effect for the size of the bicycle tire.

[0044] A support frame 6 is fixedly sleeved in the middle of the support beam 101. At least two positioning holes 604 are opened through the sides of the support frame 6 on both sides, and the two positioning holes 604 are inclined. A groove corresponding to the positioning hole 604 is provided through the rotating beam 103. A hole for the positioning bolt 601 is provided below the positioning hole 604. The positioning hole 604 and the rotating beam 103 are connected through the insertion bolt 602. A limiting band 603 for positioning support is sleeved on the insertion bolt 602.

[0045] When the rotating beam 103 needs to be folded and stored, the positioning bolt 601 is kept in the insertion state with the hole on the support frame 6 and the slot of the rotating beam 103, so that the positioning bolt 601 acts as a rotating rod. Then, the rotating beam 103 is moved so that it is horizontal with the support auxiliary beam 101. At this time, the plug 602 is inserted into the positioning hole 604 located on the lower side, so that the plug 602 is above the rotating beam 103. Then, the limiting band 603 is inserted and fixed to the plug 602 to achieve the effect of limiting the rotating beam 103 and preventing it from rotating and shifting upwards.

[0046] When the rotating beam 103 needs to be used vertically, first release the connection between the limiting band 603 and the plug 602, then pull out the plug 602 to release the rotation limitation of the rotating beam 103, then push the rotating beam 103 so that it moves vertically under the rotation support of the positioning bolt 601, then insert the plug 602 into the positioning hole 604 at the upper angle, and at the same time pass through the upper groove of the rotating beam 103, then use the limiting band 603 to insert and position the plug 602, and then fix the rotating beam 103 in the vertical position under the simultaneous action of the positioning bolt 601 and the plug 602.

[0047] At least two plug-in pieces 606 are fixedly connected to the side of the I-beam support beam 1, and at least two support frames 605 are fixedly connected to one side of the front connecting beam 102. The plug-in pieces 606 are inserted into the inside of the support frames 605.

[0048] Furthermore, a positioning bolt 601 and a plug-in bolt 602 are provided through the inside of the second support frame 605 and the plug-in piece 606, and slots for the positioning bolt 601 and the plug-in bolt 602 are provided on both sides of the second support frame 605 and the plug-in piece 606.

[0049] When using the device, first, fix the front connecting beam 102, then simultaneously insert the I-beam support beam 1 and the plug-in piece 606 into the second support frame 605, so that the positioning bolt 601 and the plug-in piece 606 and the holes on the second support frame 605 are inserted and fixed. Then, insert and fix the limiting band 603 and the plug-in bolt 602, so that the positioning bolt 601 and the plug-in bolt 602 are in a horizontal state, so as to achieve the effect of horizontal limiting between the I-beam support beam 1 and the front connecting beam 102, ensuring its stability and reliability in actual use.

[0050] When it is necessary to fold, move, or place the device, first disconnect the connection between the front connecting beam 102 and the vehicle connecting beam 7, then remove the plug 602 and the limiting band 603. At this time, the positioning bolt 601 acts as a rotating support part, flipping the front connecting beam 102 upward so that its upper surface gradually fits against the upper surface of the I-beam support beam 1, forming a folding and storage effect on the front connecting beam 102 and the I-beam support beam 1, further reducing the space occupied when it is placed.

[0051] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
