The other end of the supporting main shaft 111 is connected to the rear axle 400 through the first support rod 112 and the second support rod 113 respectively. The first support rod 112 and the second support rod 113 are respectively inclined outward in the direction toward the rear axle 400. An adjustable member 500 is also included, which is movably connected to the supporting main shaft 111. Both sides of the adjustable member 500 are connected to the first support rod 112 and the second support rod 113 respectively.

[0037] In this embodiment, the elastic frame 100 made of spring steel provides the overall vehicle body with good elasticity, reducing the tilt angle of the vehicle body and the impact on the driver, thereby improving comfort and riding experience.

One end of the bottom plate 230 is connected with the front baffle 210, and the other end of the bottom plate 230 is connected with the baffle. Of course, in actual operation, the rear baffle 220 can also be set as a channel steel with an opening towards one side of the front baffle 210 to further improve the overall strength of the battery mounting seat 200, and the front baffle 210 and the rear baffle 220 with openings respectively towards the inside of the battery mounting seat 200 can also be beneficial to realize the limiting of the battery, without the need for additional protection, which can effectively realize the limiting and fixing of the battery while preventing the battery from falling.

[0040] The seat support 120 includes a first connecting rod 121 and a second connecting rod 122, which are respectively connected to the two sides of the front baffle 210 and the rear baffle 220, and the side of the first connecting rod 121 and the second connecting rod 122 away from the battery mounting seat 200 is provided with a connecting plate 123, and the seat is mounted on the side of the seat mounting frame provided with the connecting plate 123. A plurality of fixing plates 231 are arranged below the bottom plate 230, and the vehicle body bottom frame 110 penetrates through the fixing plates 231 and is fixedly connected with the fixing plates 231. Specifically, the support shaft 111 is connected with the first support rod 112 and the second support rod 113 through the fixing plates 231. By connecting the seat support 120 and the vehicle body bottom frame 110 into one through the battery mounting seat 200, the stability of the overall vehicle body can be ensured.

[0041] Specifically, the elastic vehicle frame 100 further includes a storage rack 130, which includes a first support rod 131 and a second support rod 132, which are respectively connected to the two sides of the front baffle 210 and the rear baffle 220, and the side of the first support rod 131 and the second support rod 132 away from the battery mounting seat 200 is provided with a storage plate 133 for placing the battery controller or other parts, which makes full use of the space of the vehicle body and is beneficial to the subsequent design of the outer frame of the vehicle body.

[0042] In one embodiment, a steering handle 600 is further included, which is connected with the two wheels 700 through a steering shaft 610 respectively, and the steering shaft 610 is made of spring steel material. When the vehicle is subjected to a frontal impact, the steering shaft 610 deforms elastically to achieve buffering, avoiding the driver's hands directly receiving the impact force transmitted by the vehicle and causing hand numbness or even injury, which is beneficial to improve the comfort of the driver and ensure the driving safety of the driver.

[0043] In one of the embodiments, the adjustable member 500 comprises a connecting pressing plate 510, specifically, the middle part of the connecting pressing plate 510 is in sliding connection with the support spindle 111, and the two sides of the connecting pressing plate 510 are pressed against the first support rod 112 and the second support rod 113, respectively. The two sides of the bottom of the connecting pressing plate 510 are respectively provided with rubber pads 520, and the connecting pressing plate 510 is in abutment with the first support rod 112 and the second support rod 113 through the rubber pads 520, so as to slow down the impact between the connecting pressing plate 510 and the first support rod 112 and the second support rod 113, avoid damaging the connecting pressing plate 510 or the first support rod 112 and the second support rod 113, and affect the stability and safety of the vehicle body frame 110.

[0044] In one of the embodiments, the adjustable member 500 is provided with a locking member 530 for locking and fixing with the support spindle 111, and the locking member 530 is used to realize the fixing of the adjustable member 500 with the support spindle 111. When the position adjustment of the adjustable member 500 is needed, the locking member 530 is disassembled or loosened, and then the adjustment can be performed. In actual operation, an external thread can be arranged on the support spindle 111, and a nut 861 or the like structure is used as the locking member 530 to realize the locking and fixing, and the disassembly and assembly are convenient and the operation is simple. Of course, in addition to the present embodiment, other structures of the locking member 530 can also be used, as long as the locking and loosening operation of the locking member 530 can be realized, and such designs all belong to the protection scope of the present application.

[0045] In one of the embodiments, the front axle damping assembly 800 is further included, the front axle damping assembly 800 comprises a first damping shaft 810 and a second damping shaft 820, the upper ends of the first damping shaft 810 and the second damping shaft 820 are connected through a connecting frame 830, and the lower ends of the first damping shaft 810 and the second damping shaft 820 are connected to the two sides of the front axle 300, respectively; the connecting frame 830 is further provided with a support arm 840 connected with the front axle 300, and the support arm 840 is in rotary connection with the connecting frame 830. Specifically, as shown in the figure, Figure 6 When the connecting frame 830 is impacted by the first damping shaft 810 or the second damping shaft 820, the connecting frame 830 swings around the support arm 840, and through the swinging of the connecting frame 830, the inclination angle of the swing arm of the vehicle wheel 700 originally generated to the vehicle body is reduced by half, so as to reduce the shaking range of the vehicle body and keep the stability of the vehicle body, which is beneficial to improve the comfort of riding.

[0046] In one of the embodiments, the front axle damping assembly 800 further comprises a fixing frame 850, which is connected with the connecting frame 830 through the elastic member 860. When driving on the smooth road, the fixing frame 850 is locked and fixed with the connecting frame 830 through the elastic member 860, so that the connecting frame 830 cannot swing around the support arm 840, which can improve the rigidity of the front axle damping assembly 800, so that the vehicle is more stable when driving on the smooth road. When driving on the rough road, the elastic member 860 is removed so that the connecting frame 830 can swing around the support arm 840, which improves the damping effect of the front axle damping assembly 800. Specifically, when the position adjustment of the adjustable member 500 is needed, the locking member 530 is loosened, and then the adjustable member 500 is moved to the corresponding position, and the locking member 530 is tightened to connect and fix the adjustable member 500 with the support shaft 111.

[0047] In actual operation, the elastic member 860 comprises a nut 861 fixedly arranged on the fixing frame 850, and the connecting frame 830 is provided with a screw hole corresponding to the nut 861, and the bolt 862 is passed through the screw hole and the end of the bolt 862 is screwed into the nut 861, so as to realize the fixation of the fixing frame 850 and the connecting frame 830. When it needs to be loosened, the bolt 862 can be removed, which is simple and convenient. Of course, in addition to the present embodiment, other structures of the elastic member 860 such as buckles, straps and the like can also be used, as long as the elastic operation of the fixing frame 850 and the connecting member can be realized. Such design belongs to the protection scope of the present application.

[0048] In one of the embodiments, the connecting frame 830 is arranged as an arc-shaped elastic sheet. When the wheel 700 is impacted, the impact force is first damped through the first damping shaft 810 and / or the second damping shaft 820, and then the impact force is transmitted to the connecting frame 830 through the first damping shaft 810 and / or the second damping shaft 820. The arc-shaped elastic sheet structure of the connecting frame 830 makes the connecting frame 830 deformed when impacted, so as to realize the effect of second damping, which is beneficial to improve the overall damping performance of the vehicle, maintain the stability of the vehicle body, reduce the impact of the vehicle body on the driver, and further improve the comfort and riding experience of the driver.

[0049] In one of the embodiments, a rear axle damping assembly is further included, the rear axle damping assembly includes a damping shock absorber 900, one end of the damping shock absorber 900 is connected with the rear axle 400, the other end of the damping shock absorber 900 is connected with the seat support 120, specifically, the other end of the damping shock absorber 900 is connected with the connecting plate 123. Since the overall vehicle body is elastic, after being impacted, the overall vehicle body still has a certain elasticity, so that the driver causes the vehicle body to still shake when entering the smooth road surface from the uneven road surface. By connecting the damping shock absorber 900 between the seat support 120 and the rear axle 400, the damping performance of the overall vehicle body can be further improved, and the rebound force of the overall vehicle body can be effectively reduced, avoiding the situation that the vehicle body still shakes when entering the smooth road surface from the uneven road surface after being impacted, which is beneficial to improve the comfort and riding experience of the driver.

[0050] In one of the embodiments, the damping shock absorber 900 is a one-way damper, and is arranged to have small damping when compressed and large damping when stretched. Thus, when the vehicle body is impacted and the driver sits down, the seat will be quickly compressed downward with the driver, and the vehicle body can have normal damping effect. When the vehicle body rebounds, due to the effect of the one-way damper, the rebound speed is slowed down, avoiding the situation that the driver quickly bounces up and causes the buttocks to leave the seat, which is beneficial to improve the comfort and riding experience of the driver and also beneficial to protect the safety of the driver.

[0051] In particular, in the above embodiments, the support main shaft 111, the first support rod 112, the second support rod 113, the first connecting rod 121, the second connecting rod 122, the first support rod 131, and the second support rod 132 are all made of spring steel to realize the elasticity of the overall vehicle body. Moreover, by using the vehicle body made of spring steel, when the vehicle body is deformed due to strong impact, the deformation resistance of the vehicle body can be improved due to the characteristics of the spring steel, the risk of damage to the vehicle body is reduced, and the service life of the vehicle body is improved.

[0052] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
