However, the overall height of the bottom support structure of this back-type battery replacement box is high, which leads to a high center of gravity of the back-type battery replacement box, resulting in safety hazards when braking and turning during heavy-duty truck driving. At the same time, there is currently no bottom support structure suitable for the saddle-type battery replacement box of new energy heavy-duty trucks. Therefore, it is necessary to design a bottom support device for the battery box. Utility Model Content

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0029] Example: Refer to Figure 1-Figure 2 As shown, a bottom support device for a battery box includes:
[0030] Base 100, battery replacement connection mechanism 200, locking mechanism 300 for locking the battery box, positioning mechanism 400, first guide mechanism 500 and second guide mechanism 600;
[0031] The battery replacement connector mechanism is arranged on the upper part of the base 100, the locking mechanism 300 is arranged on the upper part of the base 100, the positioning mechanism 400 is arranged on the upper part of the base 100, the first guide mechanism 500 is used for X-axis guidance of the installation of the battery box, and the second guide mechanism 600 is used for Y-axis guidance of the installation of the battery box.
[0032] The width of the base 100 is the same as that of the heavy truck beam, and the bottom structure is lower, which is smaller and lower than the conventional heavy truck back-type vehicle-mounted base. With such a structural setting, the base 100 occupies less space and is lower in the entire vehicle, which can not only utilize the space on both sides of the heavy truck beam, but also make the overall height and center of gravity of the battery box lower.
[0033] Further, referring to Figure 2 As shown, the battery replacement connection mechanism 200 includes a mounting plate 201 and several connector joints 202 , wherein the several connector joints 202 are embedded inside the mounting plate 201 , and the mounting plate 201 is connected to the base 100 through an elastic member 203 .
[0034] The elastic member 203 enables the battery exchange connection mechanism 200 to have a certain floating effect, ensuring that the battery exchange connector assembly in the battery box is more closely connected to the connector joint 202 on the upper part of the base 100.
[0035] Among them, the locking mechanism 300 includes four locking components 301 distributed at the four corners of the base 100, and the locking component 301 includes a driving member 3011, a mounting shell 3012 and a locking pin 3013. The driving member 3011 is arranged at one end of the mounting shell 3012, one end of the locking pin 3013 is arranged inside the mounting shell 3012, and the other end of the locking pin 3013 is arranged outside the mounting shell 3012, and the locking pin 3013 arranged inside the mounting shell 3012 is connected to the moving end of the driving member 3011.
[0036] Before the battery box is placed in, the driving member 3011 drives the locking pin 3013 to retract, ensuring that the battery box has enough space to fall and be placed. When the battery box is put in place, the driving member 3011 drives the locking pin 3013 to extend to lock the battery box. With such a structural setting, the battery box is locked after being placed on the base 100, limiting the displacement of the battery box in the Z direction, ensuring that the battery box will not fall while the heavy truck is driving and the vehicle will not be powered off.
[0037] In addition, the positioning mechanism 400 includes a plurality of positioning pins 401. With such a structural arrangement, when the battery box is placed on the base 100, the battery box is first guided by the first guide mechanism 500 and the second guide mechanism 600, and then the battery box is positioned by the positioning pins 401, so that the battery replacement connector in the battery box and the connector joint 202 on the base 100 can be plugged in more accurately and conveniently, thereby achieving circuit conduction and ensuring normal use of the vehicle.
[0038] It should be noted that the first guide mechanism 500 includes two symmetrically arranged first guide components 501 , and the first guide components 501 include two symmetrically arranged guide posts 5011 , and the tops of the guide posts 5011 are chamfered.
[0039] The second guide mechanism 600 includes second guide components 601 symmetrically arranged on both sides of the base 100 . The second guide component 601 includes two symmetrically arranged guide blocks 6011 .
[0040] It should be further explained that a leaf spring 5012 is provided on the inner side of the guide post 5011. This structural arrangement is used to better limit the displacement of the battery box in the X-axis direction and ensure that the battery box is more stable on the base 100.
[0041] A mounting beam 700 is provided at the lower portion of the base 100 , and a plurality of mounting side panels 701 are provided on both sides of the mounting beam 700 .
[0042] Several buffer pads 101 are also provided on the upper part of the base 100 to cushion the battery box; load-bearing blocks 102 are also provided on both sides of the base 100 to make the weight of the battery box on the base 100 more evenly distributed.
[0043] The working principle of this utility model is as follows:
[0044] 1. When placing the battery box on the base 100, first use the first guide mechanism 500 and the second guide mechanism 600 to guide the battery box.
[0045] 2. Before the battery box is placed, the driving member 3011 drives the locking pin 3013 to retract to ensure that the battery box has enough space to fall and be placed. When the battery box is put into place, the driving member 3011 drives the locking pin 3013 to extend to lock the battery box.
[0046] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
