[0022] The following combines the drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] "Top surface", "bottom", and "bottom surface" are referenced to the normal use state of the frame of the electric logistics vehicle, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0024] As Figures 1-5 shown, a frame structure of an electric logistics vehicle includes a main frame body 1. Both ends of the main frame body 1 have horizontally extending bearing pipes 101. The bearing pipes 101 are fixedly connected with fixed brackets 103. At least one bearing pipe 101 is internally coaxially slidably fitted with a telescopic rod 102. The telescopic rod 102 is fixedly connected with a movable bracket 104. Removable shelves 2 are connected to the fixed brackets 103 and the movable brackets 104 at the same end of the main frame body 1. A distance adjusting mechanism for adjusting the distance is provided between the two shelves 2.

[0025] The above-mentioned vehicle frame is applicable to logistics electric vehicles and can increase the cargo-loading capacity of the logistics electric vehicles. The fixing bracket 103 is provided with mounting holes, and the goods shelf 2 or the cargo box can be mounted on the fixing bracket 103 through the bolt assembly 5, so as to load goods through the goods shelf 2 or the cargo box. The front and rear ends of the vehicle frame main body 1 are both provided with load-bearing pipes 101 and fixing brackets 103, so that both the front and rear ends of the vehicle frame main body 1 can have a strong cargo-loading capacity, thereby enhancing the overall cargo-loading capacity of the vehicle frame main body 1. Since when the electric vehicle is moving forward, in order not to block the line of sight and maintain the flexibility of steering, it is not suitable to load large goods in the front. Therefore, the telescopic rod 102 is mounted on the load-bearing pipe 101 at the rear end of the vehicle frame main body 1. The front and rear ends of the vehicle frame main body 1 are both provided with two load-bearing pipes 101 at the same horizontal height. Through the arrangement of the two load-bearing pipes 101, the load-bearing range can be increased and the stability of loading goods can be improved. An adjustable bracket 104 is erected between the two telescopic rods 102. The adjustable bracket 104 and the fixing bracket 103 at the tail end of the vehicle frame main body 1 are both mounted with the goods shelf 2 through the bolt assembly 5. The two goods shelves 2 can slide relative to each other, and the distance between the two goods shelves 2 can be adjusted through the distance-adjusting mechanism. The cargo box can be placed on the two goods shelves 2 or goods can be directly placed on them. Through the arrangement of the two goods shelves 2, the cargo-loading area can be increased and the cargo-loading capacity of the vehicle frame main body 1 can be enhanced. Moreover, by adjusting the distance between the two goods shelves 2, it can be adapted to load goods of different sizes, improving the convenience of use. When not loading goods, the distance between the two goods shelves 2 can also be adjusted to the minimum to reduce the overall volume of the vehicle frame main body 1 and enhance the flexibility of the electric vehicle during driving.

[0026] A further improvement is that, as Figures 3-5As shown in the figure, the distance adjustment mechanism includes a connecting rod 3 distributed parallel to the axis of the bearing pipe 101. At both ends of the connecting rod 3, there are socket pipes 202 that are coaxially and slidably fitted. The two socket pipes 202 are respectively fixedly connected to the two shelves 2. On the side surface of the connecting rod 3, there are a plurality of positioning holes 301 distributed at equal intervals along its extending direction. The socket pipe 202 has a first threaded hole 203, and a locking screw 302 is threadedly connected to the first threaded hole 203. The end of the locking screw 302 extends into one of the positioning holes 301. The cooperation between the connecting rod 3 and the socket pipe 202 realizes the guiding and supporting functions, improving the stability of the connection between the two shelves 2. When adjusting the distance between the shelves 2, turn the locking screw 302 to make it withdraw from the positioning hole 301. At this time, the shelf 2 can be pulled to move, realizing the adjustment of the distance between the two shelves 2, thereby realizing the adjustment of the loading area of the frame body 1. While improving the loading capacity, it is convenient to carry goods of different sizes; when the distance between the two shelves 2 is adjusted in place, the locking screw 302 can be screwed into the corresponding positioning hole 301 to realize the locking between the shelf 2 and the connecting rod 3. At this time, the stability between the two shelves 2 can be improved through the connecting rod 3; the cooperation between the bearing pipe 101 and the telescopic rod 102 can realize the adjustment of the movable bracket 104 while playing a supporting role for the movable bracket 104, thereby improving the stability of the support for the shelf 2.

[0027] A further improvement is that, as Figure 2 and 4 shown, the bearing pipe 101 and the frame body 1 are integrally formed, and the socket pipe 202 and the shelf 2 are integrally formed. The integrally formed structure has higher connection strength. Through the above settings, the strength of the bearing pipe 101 and the shelf 2 can be improved, and then the strength of the frame body 1 can be improved.

[0028] A further improvement is that, as Figures 3-5 shown, on the top of the opposite sides of the two shelves 2, there are clamping rods 201 provided, and the surface of the clamping rod 201 has an anti-slip layer. The setting of the clamping rod 201 can play a limiting role on the goods carried on the shelf 2, preventing the goods from falling during transportation, and then improving the stability of the loading of the frame body 1.

[0029] A further improvement is that, as Figures 3-5 shown, on both side surfaces of the shelf 2 parallel to the axis of the bearing pipe 101, there are retractable expansion struts 4 provided. The adjustment of the distance between the shelves 2 can realize the adjustment of the loading area in the front-back direction of the frame body 1. Through the expansion struts 4, the support range can be expanded in the left-right direction, further improving the stability of the support for the goods.

[0030] A further improvement is that, as Figure 5As shown, the extension strut 4 is in the same horizontal plane as the shelf 2. One end of the extension strut 4 is hinged to the shelf 2, and an elastic rope sleeve 403 is fixedly connected to the shelf 2. The rope sleeve 403 is sleeved on the other end of the extension strut 4. When the extension strut 4 is not in use, the extension strut 4 is stored on both sides of the shelf 2, and the extension strut 4 is bound to the shelf 2 through the rope sleeve 403 to prevent the extension strut 4 from rotating under the action of external force and affecting the normal driving of the electric vehicle; when the width of the goods loaded on the shelf 2 exceeds the width of the shelf 2, the rope sleeve 403 can be separated from the extension strut 4, and then the extension strut 4 is unfolded. The extension strut 4 can increase the bearing range of the shelf 2 in the width direction, thereby expanding the effective support area for the goods and improving the stability of the support for the goods.

[0031] A further improvement is that, as Figure 5 shown, a limiting member is further provided on the extension strut 4; the limiting member includes a plurality of second threaded holes 402 vertically opened on the extension strut 4, and the second threaded holes 402 are equally spaced along the extending direction of the extension strut 4. A stud 401 is threadedly connected to one of the second threaded holes 402, and the length of the stud 401 is greater than the length of the second threaded hole 402. When the extension strut 4 is unfolded, the stud 401 can be screwed into the second threaded hole 402 corresponding to the width of the goods, and the top end of the stud 401 protrudes beyond the top surface of the extension strut 4, which can play a supporting effect on the goods; by arranging the stud 401 in different second threaded holes 402, the limiting and supporting effects on goods of different widths can be realized; when a cargo box needs to be installed on the shelf 2, by rotating the extension strut 4 and adjusting the position of the stud 401 in different second threaded holes 402, the stud 401 can be accurately docked with the threaded holes at the bottom of the cargo box, improving the convenience and firmness of the docking between the cargo box and the shelf 2, and further improving the convenience of using the frame body 1.
