Detailed Description
A vehicle frame 1000 according to an embodiment of the present invention is described below with reference to fig. 1 to 13, and the vehicle frame 1000 is applied to an all-terrain vehicle, which refers to a vehicle that can travel on any terrain, and can travel freely on terrain where a normal vehicle is difficult to maneuver. Commonly known as beach vehicles in China.
As shown in fig. 1 to 3, a frame 1000 of an all-terrain vehicle according to an embodiment of the present invention may include a main frame 100, a front axle mounting device 200, a first sub-frame 300, a second sub-frame 400, a third sub-frame 600, and a roof frame 500, wherein the main frame 100 forms a main structure of the frame 1000, a cockpit 120 and a power cabin 130 may be formed in the main frame 100, the cockpit 120 may be provided for a driver and a passenger to sit therein, a driver seat and a passenger seat may be provided therein, the power cabin 130 is used for mounting and placing a power device, the power device may include an engine and/or an electric motor, and the all-terrain vehicle may be classified into a pure oil, a pure electric, and a hybrid driving form according to different power device types.
As shown in fig. 1 to 3, the front axle mounting device 200, the first subframe 300, the second subframe 400, the third subframe 600 and the roof frame 500 are all of separate structures with the main frame 100, that is, the front axle mounting device 200, the first subframe 300, the second subframe 400, the third subframe 600 and the roof frame 500 are not of an integral welding structure with the main frame 100, and all the above components are mounted and fixed at different positions of the main frame 100, thereby playing different functions.
The frame 1000 of the embodiment of the invention adopts a non-integral welding mode, so that the frame 1000 is easy to produce and manufacture, the flexibility of the arrangement of the frame 1000 can be increased, and the installation and the fixation of each functional part on the frame 1000 can be facilitated.
As shown in fig. 3 and 4, a front axle mounting device 200 is used to mount a front axle 5000, and the front axle mounting device 200 is fixed to the front end underside of the main frame 100. Conventional all-terrain vehicles generally adopt a pipe to form a front axle mounting structure on the front side of a vehicle frame, and the front axle and a hanging device positioned on the front side of the front axle need to be mounted on the mounting structure, but due to the fact that the hanging device is large in size, the pipe cannot extend to the front side of the all-terrain vehicle, and accordingly the front axle and the hanging device are difficult to mount. The front axle installation device 200 of the invention adopts a mode of independent arrangement, and can effectively adapt to the front axle 5000 and the suspension device, thereby reducing the installation difficulty of the front axle 5000 and the suspension device, and the installation reliability of the front axle 5000 and the suspension device is higher.
As shown in fig. 3,4 and 6, the first subframe 300 is mounted on the upper side of the front end of the main frame 100, and the first subframe 300 is located above the front axle mounting device 200, and the front parts of the first subframe 300, the front axle mounting device 200 and the main frame 100 form a component accommodating space. The first sub-frame 300 mainly plays a role of a supporting and mounting member, and a front portion of a housing cover of the all-terrain vehicle may be provided on the first sub-frame 300, and the first sub-frame 300 may play a role of mounting and fixing. Also, as shown in fig. 7 and 9, the component accommodation space may be used to accommodate the radiator 2000, so that the first subframe 300 may effectively protect the radiator 2000.
By arranging the first sub-frame 300 in the overall frame 1000 structure, the structural rigidity and strength of the first sub-frame 300 can be improved, the installation and fixation of each component can be facilitated, the structural strength of the frame 1000 can be further improved, and the shake of each component mounted thereon can be correspondingly reduced due to the improvement of the structural strength thereof, so that the failure rate of each component can be further reduced.
As shown in fig. 1 and 2, the lower end of the second subframe 400 is mounted on the main frame 100, and the second subframe 400 is located at the front side of the cockpit 120, and the lower end of the second subframe 400 is located at the front side of the cockpit 120, and the rear upper end of the first subframe 300 may be mounted on the second subframe 400. Wherein, a front shock absorber of a suspension device can be arranged at the front end of the second subframe 400, and a plurality of mounting points are arranged on the front shock absorber and are fixedly connected with the main frame 100.
It should be noted that, the surfaces of the main frame 100 and the second subframe 400 are required to be subjected to the painting step, and because the second subframe 400 and the main frame 100 are in independent structures, when the all-terrain vehicle is painted, the main frame 100 and the second subframe 400 can be painted respectively, so that the painting difficulty is effectively reduced, and because the part of the second subframe 400 is exposed out of the outer shell of the all-terrain vehicle, in order to better protect the second subframe 400, the paint layer on the surface of the second subframe is different from the paint layer of the main frame 100, and thus the painting cost of the main frame 100 is reduced.
As shown in fig. 12 and 13, the main frame 100 is formed with an oil tank compartment 150 inside the front portion of the cockpit 120, the upper portion of the oil tank compartment 150 is opened, the third sub-frame 600 is formed in a separate structure from the main frame 100, and the third sub-frame 600 is installed at the upper portion of the oil tank compartment 150. That is, the all-terrain vehicle of the present invention has the oil tank 7000 disposed in the cockpit 120 and the oil tank 150 disposed in the front portion (i.e., meter mounting region) of the cockpit 120, so that the space in the cockpit 120 can be reasonably utilized, and the oil tank 7000 and the power unit can be spaced apart, so that heat generated by the operation of the power unit can be prevented from being transferred to the oil tank 7000, and the safety in use of the oil tank 7000 can be ensured. In addition, by disposing the oil tank compartment 150 in the cockpit 120, the structural complexity of the frame 1000 can be reduced, the difficulty in disposing the oil tank 7000 can be reduced, and the overall weight of the all-terrain vehicle can be further made uniform.
The third subframe 600 may be conveniently installed and removed from the oil tank 7000, for example, after the oil tank 7000 is placed in the oil tank compartment 150, the third subframe 600 may be installed on the main frame 100, so that the installation reliability of the oil tank 7000 may be effectively ensured.
As shown in fig. 1 and 2, a roof frame 500 is provided above the main frame 100 and the second sub-frame 400, specifically, a roof frame 500 is mainly installed above the cockpit 120 and the power compartment 130, a front end of the roof frame 500 is installed at an upper portion of the second sub-frame 400, a rear portion of the roof frame 500 is installed on the main frame 100, and a rear portion of the roof frame 500 is located at a rear side of the cockpit 120. The roof rack 500 can play a role in protecting drivers and passengers, and when the all-terrain vehicle turns over, the roof rack 500 can firstly contact and collide with the ground, so that the bodies of the drivers and the passengers can be prevented from directly contacting and colliding with the ground, and the safety of the drivers and the passengers can be ensured.
Therefore, according to the frame 1000 of the all-terrain vehicle in the embodiment of the invention, by integrating the main frame 100 with each different auxiliary frame 1000 and the front axle mounting device 200, the frame 1000 can be easily mounted and arranged, the difficulty of mounting components of the frame 1000 can be reduced, the manufacturing cost of the frame 1000 can be reduced, and the structural reliability of the frame 1000 can be ensured.
