Description

Technical Field

[0001] This utility model belongs to the field of vehicle frame processing equipment, and more specifically, it relates to an overall vehicle frame mounting rack. Background Technology

[0002] The frame is the main load-bearing structure of a bicycle or electric bicycle. It integrates and connects core components such as wheels, fork, handlebars, seat, drivetrain, and braking system. It also bears static loads (such as rider weight) and dynamic loads (such as pedaling force and road impact) during riding. It is the mechanical and functional integration foundation of the entire vehicle.

[0003] Its core structure consists of the following components: the head tube provides the mounting interface for the front fork steerer tube; the seat tube is a vertical or inclined tubular structure, with the upper end connecting to the top tube and the lower end intersecting with the bottom bracket, serving as the mounting carrier for the saddle (seatpost); the rear fork is a frame structure extending from the bottom of the seat tube to the rear wheel hub, including the top and bottom forks; the down tube is a tubular structure extending from the bottom bracket to below the head tube, serving as the main load-bearing beam of the frame; the bottom bracket is the node where the down tube, seat tube, and rear fork top forks intersect, with a built-in bottom bracket mounting position, providing a fixed base for the crankset (crank system), and all pedaling forces are transmitted to the rear wheel through the bottom bracket.

[0004] If the frames are directly stacked or placed randomly after production, the residual welding stress will cause the tubing to deform due to gravity (for example, when aluminum alloy is naturally cooled after welding, unsupported tubing is prone to bending); at the same time, stacking and squeezing will change the relative position of the tubing and destroy the preset geometric parameters.

[0005] The placement rack uses a customized positioning structure (such as slots that match the profile of the vehicle frame and adjustable brackets) to forcibly fix the vehicle frame during circulation, temporary storage, and inspection, thus avoiding precision loss caused by external forces.

[0006] Traditional racks typically use suspension and lifting methods to place the vehicle frame, which often causes the frame to sway during use. For example, Chinese patent CN210551124U discloses a vehicle frame rack that uses a suspension method to place the vehicle frame. Utility Model Content

[0007] To address the above deficiencies, this utility model provides an integrated vehicle frame mounting bracket, including a crossbeam and vertical bars. The two ends of the crossbeam are respectively fixed to two vertical bars by right-angle fittings, and several flat-angle fittings are respectively fitted on the crossbeam and vertical bars.

[0008] Each of the aforementioned flat-angle kits is respectively equipped with a pivot for fixing the headset of the frame, a support plate for supporting the chainstay, a fork plate for supporting the front fork, a limiting plate for fixing the rear seat fork, and a clamp for limiting the downtube, seat tube, and top tube.

[0009] The two ends of the crossbeam are also provided with through connecting grooves, and two adjacent crossbeams are assembled into a whole by connecting rods and bolts.

[0010] Furthermore, there are no fewer than four clamps, which are respectively installed at each branch end of the connecting rod, and the connecting rod is connected to the flat angle fitting at the lower tube.

[0011] Furthermore, the clamp includes two V-shaped clamps, the connecting ends of which are hinged by spring pins, and the other end is an openable opening.

[0012] Furthermore, the limiting plate includes a support plate and an adjusting clamp plate installed on the support plate. The ends of the two adjusting clamp plates that are far apart from each other are provided with columnar protrusions for being fitted by the rear fork.

[0013] Furthermore, the assembly end of the connecting rod is integrally formed with a connecting panel, and slots are provided at the four corners of the connecting panel. The slots and the screw holes at the corners of the connecting grooves are symmetrical.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] Compared to traditional suspended racks, this invention uses different fixing structures for different parts of the frame, such as clamping, fastening, and supporting, to achieve a more stable fixation of the frame. Even if the rack is accidentally bumped in the workshop, it will not cause the frame to tilt or fall off.

[0016] Furthermore, the individual shelves can be spliced ​​and combined to form a whole, making it easier to move the entire unit. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figures 1 to 2 As shown, this embodiment provides an overall vehicle frame mounting frame, including a crossbeam 1 and a vertical bar 2. The two ends of the crossbeam 1 are fixed to the two vertical bars 2 by right-angle fittings 21, and several flat-angle fittings 22 are respectively fitted on the crossbeam 1 and the vertical bars 2.

[0025] Several flat-angle kits 22 are each equipped with a pivot 9 for securing the headset of the frame 8 (e.g., Figure 4 As shown, the linkage 12 includes: a support plate 5 for fixing the headset after installation; a fork plate 6 for supporting the front fork; a limiting plate 4 for fixing the upper rear fork; and clamps 7 for limiting the lower tube, riser tube, and top tube. There are at least four clamps 7, each installed at one of the branches of the linkage 12. Figure 3 As shown, clamp 7 includes two V-shaped clamps (such as...) Figure 3 As shown in the attached diagram (71 and 72), the two V-shaped clamps are hinged at the connecting ends by spring pins, and the other end is an openable opening. The connecting rod 12 is connected to the flat angle fitting 22 at the lower tube. It should be noted that both the right angle fitting 21 and the flat angle fitting 22 are two panels fixed by bolts. The difference between the two is that they are used at the corner and the flat surface. It can be understood that the right angle fitting 21 is formed by two flat angle fittings 22 in one piece. It has two sleeved connecting ends and is a traditional industrial connector, which will not be described in detail here.

[0026] In detail, the support plate 5 is a flat plate, and the limiting plate 4 includes a support plate 5 and an adjusting clamp installed on the support plate 5. The adjusting clamp is fixed in the slot opened in the support plate 5 by a movable connection. The movable connection can be made by opening several equally spaced slots for insertion, or by setting a sliding groove, the adjusting clamp can be inserted into the sliding groove, and then a tension spring is added for spring-back clamping. The ends of the two adjusting clamps that are far apart from each other are provided with columnar protrusions for being fitted by the rear fork. The front fork plate 6 has the same function as the limiting plate 4, and is also provided with columnar protrusions for being fitted by the front fork to realize the limiting function of each part.

[0027] Both ends of the crossbeam 1 are provided with through connecting grooves 11. Two adjacent crossbeams 1 are assembled into a whole by connecting rods 10 and bolts. The assembly end of the connecting rod 10 is integrally formed with a connecting panel. The four corners of the connecting panel are provided with slots. The slots are symmetrical with the screw holes opened at the corners of the connecting grooves 11. That is, when splicing is required, the connecting panels of the two connecting rods 10 are attached together and then long bolts are passed through. The two ends of the long bolts are threaded to the screw holes at the two crossbeams 1 respectively.

[0028] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
