Description

Technical Field

[0001] The utility model relates to the technical field of battery vehicles, in particular to a novel driving-for-hire vehicle frame. Background Art

[0002] With the increase in demand for designated driver electric vehicles on the market, the battery capacity is getting larger and larger, and the weight is also increasing accordingly. There are currently two ways to dispose of batteries for designated driver electric vehicles. One is to place the battery on the rear rack of the frame. In this way, since the battery is above the rear wheel, the weight will be on the rear wheel. When passing through some bumpy roads, the heavy weight can easily cause the wheel to break. At the start, due to the heavy tail end and the rear-wheel drive, it is particularly easy to tilt the head, which has a safety impact on driving. The second is to place the battery vertically behind the seat tube. In this way, in order to avoid the seat being too high, the battery will be placed as low as possible and close to the ground. When riding, it is easy to touch the ground and it is easy to get water in, affecting the use.

[0003] Therefore, it is urgent to design a novel replacement driving vehicle frame structure to overcome the above-mentioned deficiencies of one or more prior arts. Summary of the Invention

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: to provide a new type of designated driving vehicle frame, characterized in that it includes: a middle tube, the front side of the middle tube is fixedly connected to a cross beam tube, the cross beam tube can be folded from a predetermined position, the rear side of the middle tube is connected to a battery compartment rack, batteries are placed in the battery compartment rack, the two sides of the battery compartment rack are rotatably connected to shock absorbers, the bottom of the middle tube is connected to a rear fork, the end of the rear fork away from the reinforcement plate is rotatably connected to the shock absorber, the longitudinal section of the battery compartment rack is in the shape of a "7", and the battery is adapted to the battery compartment rack.

[0005] In a preferred embodiment, a reinforcing plate is further connected to the bottom of the middle tube, and the end of the rear fork away from the connection with the shock absorber is rotatably connected to one end of the reinforcing plate.

[0006] In a preferred embodiment, the reinforcing plate is further connected to a control box compartment at one end away from the rear fork, and the top of the control box compartment is connected to the crossbeam tube.

[0007] In a preferred embodiment, a waist hole is further provided at one end of the crossbeam tube adjacent to the middle tube.

[0008] In a preferred embodiment, the two shock absorbers are connected to one end of the battery compartment frame via a connecting shaft.

[0009] In a preferred embodiment, the end of the rear fork connected to the shock absorber is further provided with a hook plate, and the end of the shock absorber away from the battery compartment frame is rotatably connected to the hook plate.

[0010] In a preferred embodiment, the end of the reinforcement plate connected to the rear fork is also fixedly connected to the bottom of the battery compartment rack.

[0011] The beneficial effect of the present invention is that through the structural design of the "7"-shaped battery compartment rack, the two placement methods in the existing technology are combined together, so that part of the battery is placed vertically and part is placed horizontally, which can not only avoid the weight of the battery being entirely pressed on the rear wheel, but also avoid the vertically placed part being too high or too low, and can solve the problem of the nose tilting, and avoid the battery being too close to the ground, killing two birds with one stone, and can also ensure battery life and improve practicality.

[0021] like Figure 1-Figure 2As shown, the utility model provides a new type of substitute driving frame, which is characterized in that it includes: a middle tube 10, a crossbeam tube 11 is fixedly connected to the front side of the middle tube 10, and the crossbeam tube 11 can be folded from a predetermined position, and the rear side of the middle tube 10 is connected to a battery compartment rack 12, in which batteries 13 are placed, and shock absorbers 14 are rotatably connected to both sides of the battery compartment rack 12, and reinforcing plates 15 are connected to both sides of the bottom of the middle tube 10, and the end of the reinforcing plate 15 facing the rear side of the middle tube 10 is connected to a rear fork 17, and the end of the rear fork 17 away from the reinforcing plate 15 is rotatably connected to the shock absorber 14, and the longitudinal section of the battery compartment rack 12 is "7"-shaped, and the battery 13 is adapted to the battery compartment rack 12.

[0022] Furthermore, the end of the reinforcing plate 15 away from the rear fork 17 is also connected to a control box compartment 16 , and the top of the control box compartment 16 is connected to the crossbeam tube 11 .

[0023] Furthermore, a waist hole 111 is formed at one end of the crossbeam tube 11 adjacent to the middle tube 10 .

[0024] Furthermore, the two shock absorbers 14 are connected to one end of the battery compartment frame 12 via a connecting shaft 141 .

[0025] Furthermore, a hook piece 171 is further provided at one end of the rear fork 17 connected to the shock absorber 14 , and an end of the shock absorber 14 away from the battery compartment frame 12 is rotatably connected to the hook piece 171 .

[0026] Furthermore, one end of the reinforcing plate 15 connected to the rear fork 17 is also fixedly connected to the bottom of the battery compartment frame 12 .

[0027] Specifically, the top of the middle tube 10 is used to connect the seat, the bottom of the middle tube 10 is used to connect the five-way bridge, and a crossbeam tube 11 is fixedly connected to the front side of the upper middle part of the middle tube 10. The crossbeam tube 11 is used to connect the handlebars and the front fork. The crossbeam tube 11 is provided with a folder at a predetermined position, so that the crossbeam tube 11 can be folded in half from the position where the folder is located to achieve the folding of the frame, reduce the overall length of the frame, and facilitate carrying; at the same time, in order to solve the problems existing in the two battery 13 placement methods in the prior art, a battery compartment rack 12 is connected to the rear side of the middle tube 10, and the battery compartment rack 12 includes a vertical portion and a horizontal portion. The vertical portion and the horizontal portion are combined to form a "7"-shaped battery compartment rack 12. The interior of the battery is provided with a battery 13 adapted to the battery compartment frame 12. The battery 13 is also in the shape of a "7". Through the structural design of the battery compartment frame 12, the two placement methods in the prior art are combined, so that the battery 13 is partially placed in a vertical position and partially placed in a horizontal position, which can avoid the weight of the battery 13 being fully pressed on the rear wheel and the vertically placed part being too high or too low. It can solve the problem of tilting the head and avoid the battery 13 being too close to the ground, killing two birds with one stone. In order to improve the riding comfort, the battery compartment frame 12 is also connected to the shock absorber 14. At the same time, a rear fork 17 is connected to the bottom of the middle tube 10. The end of the rear fork 17 away from the middle tube 10 is connected to a hook piece 171. The hook piece 171 is rotatably connected to the shock absorber 14. When driving, the shock absorber 14 absorbs the impact force or the extrusion force, and then slowly releases the absorbed force, thereby reducing the amplitude of the bounce and achieving the shock absorption effect. Since there are two shock absorbers 14, in order to ensure that the two shock absorbers 14 are evenly stressed, the two shock absorbers 14 are connected to the battery compartment frame 12 at one end thereof through a connecting shaft 141. The connecting shaft 141 passes through the battery compartment frame 12, so that when the force is transmitted from the battery compartment frame 12, the force is evenly transmitted to the two shock absorbers 14 through the connecting shaft 141, thereby avoiding uneven stress and affecting the shock absorption effect, and also avoiding deformation of the frame. A patch is also fixedly welded at the bottom of the middle tube 10. The reinforcing plate 15 and the rear fork 17 are rotatably connected to the reinforcing plate 15 at one end away from the hook piece 171. When the middle tube 10 is subjected to force, the middle tube 10 will sink under the action of the force through the rotatable connection between the rear fork 17 and the reinforcing plate 15, so that the shock absorber 14 can play a shock-absorbing effect; a control box compartment 16 is also connected to the end of the reinforcing plate 15 away from the rear fork 17. The top of the control box compartment 16 is detachably connected to the crossbeam tube 11. The control box compartment 16 is arranged below the crossbeam tube 11, which can not only increase the overall strength of the frame, but also prevent water from entering the control box compartment 16; in order to facilitate the movement of the frame after folding, a waist hole 111 is opened in the end of the crossbeam tube 11 adjacent to the middle tube 10, eliminating the need for an additional handle.

[0028] In summary, the present application combines the two placement methods in the prior art through the structural design of the "7"-shaped battery compartment rack 12, so that the battery 13 is placed partially in a vertical position and partially in a horizontal position. This can not only avoid the weight of the battery 13 being entirely pressed on the rear wheel, but also avoid the vertically placed part being too high or too low. It can not only solve the problem of the nose tilting, but also avoid the battery 13 being too close to the ground, killing two birds with one stone, and can also ensure battery life and improve practicality.

[0029] The present invention is not limited to what is described in the specification and implementation methods, and therefore can be easily realized by those skilled in the art. Other advantages and modifications are possible without departing from the spirit and scope of the general concept defined by the claims and their equivalents. The present invention is not limited to the specific details, representative devices, and illustrated examples shown and described herein.
