Description

[Technical Field]

[0001] The present invention relates to the field of vehicle technology, and more particularly to electric four-wheel all-terrain vehicles. [Background technology]

[0002] As society develops, electric transport vehicles are widely used in all fields. When conventional four-wheeled transport vehicles travel over uneven terrain, such as farm roads, only three wheels are able to bear the force. This is because the four wheels of conventional products are fixed to the vehicle frame, meaning that when the terrain is uneven, the four tires cannot sway up and down to accommodate changes in the ground surface. Therefore, there is a need for all-terrain electric four-wheeled transport vehicles for auxiliary use.

[0003] Chinese utility model application number CN201320162697.3 discloses a transport vehicle. The transport vehicle can be converted into two-wheeled, four-wheeled, or other configurations depending on the terrain, using a simple structure consisting of a hinge shaft that passes through the vehicle bed and a locking member that can fix the rotation angle of the hinge shaft. During operation, the device ensures stability by applying force to different wheels. This not only affects the weight of the vehicle, but also significantly accelerates component wear, causing breakdowns and shortening the transport vehicle's service life, and making the transport vehicle inconvenient to use and dispose of.

[0004] In addition, a utility model patent with Chinese application number CN201820706646.5 discloses a full-time 4WD with a steerable new energy all-terrain pushcart. Even if one wheel of the pushcart slips, the other wheels provide stable power to maintain the load movement of the entire vehicle, allowing for excellent balance and steerability even on harsh road surfaces. Even if one set of drive axles fails, the other set of drive axles can operate normally and independently without the need for external traction. When this device is in use, the installation of drive axles ensures reliable operation of one set of wheels, but the installation of four sets of drive axles is too costly, significantly impacting the price of such a simple electric pushcart.

[0005] Therefore, to solve the above-mentioned problems, an all-terrain electric four-wheeled transport vehicle is provided. Summary of the Invention [Problem to be solved by the invention]

[0006] The object of the present invention is to provide an all-terrain four-wheeled electric cart that solves the problems in the background art described above.

The terrain adaptation mechanism allows the vehicle to adapt to different terrains and extend the service life of the vehicle body.

[0009] In a preferred technical solution of the present invention, the rotation range of the connecting block is -30° to 30°, which can adapt to different terrains.

[0010] As a preferred technical solution of the present invention, different modules are installed on the flat plate structure on the upper layer of the above-mentioned loading plate, and in the case of a flat plate truck, a protective bar is installed, and a loading platform is used for construction, and the loading platform and protective bar are used according to the situation.

[0011] In a preferred technical solution of the present invention, adjustable extension / retraction protection bars are provided on both sides of the length of the support plate and on the front of the support plate, making it easy to adjust the position of the protection bars.

[0012] As a preferred technical solution of the present invention, the protective bar is in sliding contact with the mounting plate below the mounting plate, and the mounting plate is engaged with a lock knob to be fixedly connected, and the protective bars on both sides of the mounting plate extend in the width direction below the vehicle body, making it easy to regulate the position of the protective bar.

[0013] As a preferred technical solution of the present invention, a fixing pin is further mounted vertically on the shaft at the upper end of the rear wheels and main wheels to facilitate locking the rear wheels and main wheels, and the position of the rear wheels and main wheels is restricted by the installation of the fixing pin.

[0014] In a preferred technical solution of the present invention, a collision prevention block having a protective effect is attached to the outer side of the loading plate, so that the loading plate has a protective effect.

[0015] Compared with the prior art, the present invention has the following significant advantages: the all-terrain electric four-wheeled vehicle is equipped with a terrain adaptation mechanism, and by using the terrain adaptation mechanism, when it is necessary to traverse different terrains, the rear wheels stick to the ground and do not tilt, thereby achieving the purpose of traversing various terrains. The specific details are as follows: 1. The installation of a terrain adapting mechanism allows it to adapt to different terrains, causing the top of the loading plate to tilt. The installation of a rear wheel rotatably connected to the bottom of the support block allows the middle of the connecting block to be rotatably connected to the outside of the pivot axis, allowing it to adapt to different terrains due to gravity. 2. The connecting block allows the rear wheels to rotate at an angle between -30° and 30°, making it adaptable to various terrains.
