This type of electric tractor combines the functions of a traditional tractor with modern remote control technology, making operation more flexible and convenient.

[0003] In order to facilitate remote control, the existing remote control type electric tractor is generally light in structure, which results in a small weight of the goods to be transported or towed. For such small electric tractors, in order to be used continuously, the battery is generally replaced to maintain the battery life. However, the battery installation structure in the current small electric tractor is compact and needs to be installed with a limit structure, which results in cumbersome operation when disassembling and installing the battery, wasting time and affecting the speed of disassembling and replacing the battery. In view of this, we propose a remote control type electric tractor. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Embodiment: A remote control electric tractor, see Figures 1 to 5 , including an electric tractor body 1 and a control box 2. This type of electric tractor has two operating modes: manual driving and remote control driving, which can be switched according to the needs of actual work scenarios. For example, the TOYOTA 4CBTYR electric remote control tractor can achieve seamless conversion between these two modes in on-site demonstrations. The control box 2 is used to receive remote control commands and drive the moving wheels to rotate. A battery box 3 is fixedly provided inside the control box 2. Two box covers are provided on the control box 2, one of which is aligned with the position of the battery box 3. A battery 4 is installed inside the battery box 3. The installation position of the battery 4 can be limited by the battery box 3. Two folding lifting components 5 are fixedly installed on the upper surface of the side plate at the bottom of the inner cavity of the battery box 3. A bottom plate 6 connected to the folding lifting component 5 is fixedly provided at the bottom of the battery 4. A support block 7 connected to the bottom plate 6 is fixedly provided on the upper surface of the folding lifting component 5. The connection position can be limited by the combination of the bottom plate 6 and the support block 7. In this way, the battery 4 can be controlled to move up and down by the folding lifting component 5;

[0025] A slot 701 is provided on the side where the support block 7 and the bottom plate 6 are in contact, and a plug plate 601 combined with the slot 701 is fixedly provided on the bottom side of the bottom plate 6, and the slot 701 and the plug plate 601 are connected obliquely; the combination of the plug plate 601 and the slot 701 can limit the installation position of the bottom plate 6, and the oblique insertion method makes it possible for the bottom plate 6 to be moved to the support block 7 in an inclined manner, so that it can only be moved at the same angle when separated, so that the connection position can be fixed under the weight of the battery 4 itself, and it is not easy to get loose.

[0026] Specifically, the front and rear groove surfaces of the slot 701 are both inclined portions 702 inclined forward, the angle between the front inclined portion 702 and the bottom groove surface of the slot 701 is an acute angle 703, and the angle between the rear inclined portion 702 and the bottom groove surface of the slot 701 is an obtuse angle 704; the acute angle 703 and the obtuse angle 704 can be formed by setting the inclined portions 702 on both sides, and such a shape setting can ensure a certain inclined surface to achieve the effect of oblique insertion limiting.

[0027] Furthermore, the cross-sectional shape of the plug board 601 is the same as the cross-sectional shape of the slot 701; the same shape facilitates docking and can ensure the strength of the connection.

[0028] Furthermore, the surfaces of the plug board 601 that contact the slot 701 are all smooth surfaces; the provision of smooth surfaces can reduce the resistance of contact movement and facilitate the insertion of the plug board 601.

[0029] It is worth mentioning that a mounting base 8 is fixedly provided on the upper surface of the box cover of the control box 2, and the mounting base 8 is connected to the inner cavity of the control box 2, and a reinforced antenna 9 is installed on the upper surface of the mounting base 8; the setting of the reinforced antenna 9 can enhance the effect of the control box 2 receiving commands, avoid the problem of remote control failure due to electromagnetic influence, and maintain a good control effect. The setting of the mounting base 8 can adjust the installation position of the reinforced antenna 9.

[0030] It is worth noting that a protective cover 10 is installed on the upper surface of the box cover of the control box 2 and outside the reinforced antenna 9, and positioning blocks 801 are fixedly provided on the side walls of the four sides of the mounting base 8, and the positioning blocks 801 are in contact with the inner wall of the protective cover 10, and a positioning groove 802 is opened on the side wall of the positioning block 801, and a connecting block 1001 combined with the positioning groove 802 is fixedly provided on the inner wall of the protective cover 10; the setting of the protective cover 10 can protect the reinforced antenna 9 to prevent damage caused by accidental contact, and the setting of the positioning block 801 can limit the installation position of the protective cover 10, which is convenient for the connecting block 1001 to be quickly inserted into the positioning groove 802. At the same time, the combination of the two can enhance the stability of the installation position of the protective cover 10.

[0031] It is worth mentioning that a strip groove 1002 is provided on the side plate of the protection cover 10, which can provide protection without affecting the reception of instructions.

[0032] Working principle: first, place the bottom plate 6 on the battery 4 on the upper side of the support block 7 so that the plug plate 601 is aligned with the position of the slot 701, and then move it downward by oblique insertion to insert the plug plate 601 into the inside of the slot 701, so that the battery 4 can be fixedly installed on the upper side of the folding lifting component 5, and then the battery 4 can be driven to move downward by controlling the folding lifting component 5 so that it can be installed in the battery box 3. Through such structural cooperation, the limiting structure for installing the battery 4 can be omitted. When it is necessary to disassemble and replace the battery 4, it is only necessary to open the box cover at the corresponding position, and then move it to the top of the battery box 3 through the folding lifting component 5, and then move it upward by oblique support to remove it, so as to achieve the effect of quick disassembly, effectively reducing the operating steps of disassembling and assembling the battery 4, and the oblique insertion method can ensure the tightness of the connection under the gravity of the battery 4, and there will be no offset problem, which ensures the installation strength. Through the cooperation of the overall structure, the battery 4 can be quickly replaced to reduce the waste of time. The reinforced antenna 9 set on the control box 2 can improve the effect of receiving instructions and reduce the problem of electromagnetic interference on instruction reception.
