[0039] The tank body connection assembly 1 according to the embodiment of the utility model includes a battery frame 100 , a tank body 200 and a drawstring assembly 300 .

[0040] The battery frame 100 is suitable for being fixed to a vehicle frame, and the battery frame 100 is provided with a plurality of first connection parts 110, the tank body 200 is provided below the battery frame 100, the strap assembly 300 includes an adjusting strap 310 and a plurality of second connection parts 320, the plurality of second connection parts 320 are provided at both ends of the adjusting strap 310, the adjusting strap 310 is connected to the tank body 200, and the plurality of second connection parts 320 and the plurality of first connection parts 110 are connected one by one to fix the tank body 200 to the battery frame 100.

[0041] The tank body 200 may be a urea tank but is not limited to a urea tank, or the tank body 200 may also be other components.

[0042] In addition, the adjustment strap 310 is connected to the tank body 200 , and the adjustment strap 310 can extend along the circumference of the tank body 200 , that is, the adjustment strap 310 can surround the tank body 200 , and then the adjustment strap 310 can be used to lift and fix the tank body 200 from the bottom of the tank body 200 .

[0043] According to the tank body connection assembly 1 of the embodiment of the utility model, by fixing the battery frame 100 to the vehicle frame, that is, the battery frame 100 is fixed relative to the vehicle frame, and then fixing the tank body 200 to the battery frame 100, the tank body 200 can be fixed relative to the vehicle frame while achieving relative fixation between the tank body 200 and the battery frame 100. In addition, the tank body 200 is arranged below the battery frame 100, that is, in the up and down direction, the tank body 200 can be directly hung on the battery frame 100, and the structural arrangement is more reasonable, which is convenient for disassembly and assembly of the tank body 200.

[0044] In addition, by providing the battery frame 100 with a first connection portion 110 and the drawstring assembly 300 with a second connection portion 320, the first connection portion 110 and the second connection portion 320 are connected. Compared with the tank body connection assembly in the related art, the tank body connection assembly 1 in the embodiment of the utility model omits the connecting crossbeam. With this arrangement, the drawstring assembly 300 can be directly connected to the battery frame 100, the number of parts of the tank body connection assembly 1 can be smaller, the connection structure of the drawstring assembly 300 and the battery frame 100 is simpler, the assembly of the tank body 200 and the battery frame 100 is simpler, and the fixing structure of the tank body 200 can be simplified, which is beneficial to improving the assembly efficiency of the tank body 200, facilitating the disassembly and assembly of the tank body 200, and making maintenance more convenient.

[0045] Furthermore, the battery frame 100 may be provided with a plurality of first connection parts 110 , and the drawstring assembly 300 may be provided with a plurality of second connection parts 320 , and the plurality of first connection parts 110 and the plurality of second connection parts 320 are connected in a one-to-one correspondence.

[0046] Specifically, a plurality of first connection portions 110 may be disposed on opposite sides of the width direction of the battery frame 100, and the second connection portions 320 at both ends of the adjusting strap 310 may be respectively connected to the first connection portions 110 on both sides of the width direction of the battery frame 100, thereby enabling the strap assembly 300 and the battery frame 100 to be connected and fixed, so that the tank body 200 may be fixed to the battery frame 100 using the strap assembly 300, and the connection between the plurality of first connection portions 110 and the plurality of second connection portions 320 may be more stable and reliable, and the connection between the adjusting strap 310 and the battery frame 100 may be more reliable, thereby further improving the stability of the fixation of the tank body 200.

[0047] In this way, the tank body connection assembly 1 according to the embodiment of the utility model can directly connect the pull strap assembly 300 to the battery frame 100, thereby simplifying the connection structure between the tank body 200 and the battery frame 100, and the disassembly and assembly of the tank body 200 is more convenient and quick, and is easy to maintain.

[0048] In some specific embodiments of the present invention, Figure 1-Figure 5 and Figure 7 As shown, the first connection portion 110 is configured as a clamping groove, and the second connection portion 320 is configured as a clamping column. The clamping column passes through the clamping groove and is clamped with the clamping groove.

[0049] Specifically, the snap-in groove can pass through the wall of the battery frame 100. By snap-connecting the snap-in column and the snap-in groove, the end of the drawstring assembly 300 can be detachably fixed to the battery frame 100, and then the drawstring assembly 300 can be connected and fixed to the battery frame 100. Moreover, the snap-in connection structure is simple, and the first connection part 110 and the second connection part 320 are reliably connected and easy to disassemble and assemble, which is conducive to simplifying the disassembly and assembly of the drawstring assembly 300 and the battery frame 100, and further improving the disassembly and assembly efficiency of the tank body 200.

[0050] In addition, it should be noted that the cross-sectional shape of the clamping column can be circular, that is, the clamping column is cylindrical, which is conducive to reducing the friction between the clamping groove and the clamping column, and the assembly of the clamping part and the clamping groove is easier and more labor-saving. Of course, the cross-sectional shape of the clamping column can also be elliptical, rectangular or other polygonal shapes.

[0051] Furthermore, if Figure 4 and Figure 6 As shown, the first connecting portion 110 includes an insertion hole 111 and a sliding groove 112 .

[0052] The insertion hole 111 is for inserting the second connection part 320, and the sliding groove 112 is connected to the insertion hole 111, so as to allow the second connection part 320 to slide to the sliding groove 112 and stop at the sliding groove 112. In other words, the second connection part 320 can be inserted into the insertion hole 111 first, and then slide into the sliding groove 112, so as to snap-fit ​​the second connection part 320 with the sliding groove 112, thereby realizing the snap-fit ​​connection between the second connection part 320 and the first connection part 110.

[0053] In addition, the diameter of the insertion hole 111 is larger than the width of the sliding groove 112. In other words, the diameter of the insertion hole 111 is larger than the maximum width of the sliding groove 112. In this way, the diameter of the insertion hole 111 can be larger, so that the second connecting part 320 can pass through the insertion hole 111, which is conducive to simplifying the assembly between the second connecting part 320 and the first connecting part 110, and the assembly is more convenient and quick.

[0054] Furthermore, if Figure 1-Figure 3 , Figure 5 and Figure 6 As shown, the insertion hole 111 is located at a side of the battery frame 100 in a horizontal direction, and the sliding groove 112 extends from the insertion hole 111 to the bottom of the battery frame 100 .

[0055] For example, the insertion hole 111 may be provided at one side in the width direction of the battery frame 100 .

[0056] With such a configuration, the insertion hole 111 can be higher than the sliding groove 112. When the second connection part 320 slides from the insertion hole 111 into the sliding groove 112, the second connection part 320 can be connected to the bottom of the battery frame 100. In this way, the second connection part 320 is not easy to escape from the insertion hole 111, thereby preventing the second connection part 320 from being separated from the first connection part 110, further improving the connection stability between the second connection part 320 and the first connection part 110, and making the connection between the pull strap assembly 300 and the battery frame 100 more reliable.

[0057] Moreover, by arranging the insertion hole 111 on the side of the battery frame 100 in the horizontal direction, the operable space on the side of the battery frame 100 is larger, and when the second connection part 320 is inserted into the insertion hole 111, the operation is more convenient and more efficient.

[0058] In some specific embodiments of the present invention, Figure 7 As shown, the second connecting portion 320 includes a connecting rod 321 and a stopping rod 322 .

[0059] The connecting rod 321 is connected to the end of the drawstring assembly 300, the stop rod 322 is connected to the end of the connecting rod 321 away from the drawstring assembly 300, the central axis of the connecting rod 321 is perpendicular to the central axis of the stop rod 322, and the connecting rod 321 is connected to the middle of the length direction of the stop rod 322, wherein the length of the connecting rod 321 is greater than the outer diameter of the stop rod 322.

[0060] The connecting rod 321 is connected to the middle of the length direction of the stop rod 322, which means that the connecting rod 321 is connected between the two ends of the length direction of the stop rod 322, but is not limited to the middle of the length direction of the stop rod 322. In this way, both ends of the stop rod 322 can protrude from the connecting rod 321 along its length direction, so that the two ends of the stop rod 322 can be clamped in the sliding groove 112 to prevent the stop rod 322 from being separated from the sliding groove 112, and the connection between the second connecting part 320 and the first connecting part 110 is more reliable.

[0061] Therefore, when assembling the drawstring assembly 300 and the battery frame 100, the stop rod 322 can be first inserted into the insertion hole 111, and then the connecting rod 321 can be rotated to make the stop rod 322 extend along the width direction of the sliding groove 112 and slide to the bottom of the sliding groove 112. At this time, the stop rod 322 can be stopped by the side wall of the sliding groove 112, that is, the stop rod 322 is clamped on the top of the bottom wall of the battery frame 100, and the battery frame 100 can fix the drawstring assembly 300 in the up and down directions, and then the drawstring assembly 300 can be used to lift and fix the tank body from the bottom of the tank body 200.

[0062] Moreover, after the second connecting part 320 and the first connecting part 110 are assembled in place, the connecting rod 321 can be inserted into the sliding groove 112, and the groove walls on both sides in the width direction of the sliding groove 112 can stop the connecting rod 321, that is, the sliding groove 112 can limit the movement of the connecting rod 321 in the length direction of the tank body 200, further improving the fixing stability of the second connecting part 320, so that the tank body 200 can be more reliably fixed to the battery frame 100.

[0063] In addition, the length of the stop rod 322 is greater than the outer diameter of the connecting rod 321. This arrangement can ensure that the two ends of the stop rod 322 in the length direction can protrude from the outer peripheral surface of the connecting rod 321, that is, the stop rod 322 and the connecting rod 321 can be in a "T" shape to ensure that the end of the stop rod 322 can be clamped on the side wall of the sliding groove 112, and the pull strap assembly 300 will not be detached from the battery frame 100.

[0064] In some specific embodiments of the present invention, Figure 4 As shown, the outer diameter of the connecting rod 321 is not greater than the slot width of the sliding slot 112 .

[0065] Specifically, the outer diameter of the connecting rod 321 is not greater than the inner diameter of the insertion hole 111 and the minimum width of the sliding groove 112. This configuration facilitates the insertion and removal of the connecting rod 321 in the insertion hole 111, and facilitates the sliding of the connecting rod 321 in the sliding groove 112, further simplifies the disassembly and assembly of the second connecting part 320 and the first connecting part 110, and makes the disassembly and assembly of the pull belt assembly 300 and the battery frame 100 more convenient and quick.

[0066] In some specific embodiments of the present invention, Figure 4 As shown, the outer diameter of the stop rod 322 is not greater than the inner diameter of the insertion hole 111 , and the length of the stop rod 322 is greater than the slot width of the sliding slot 112 .

[0067] The length of the stopping rod 322 is greater than the width of the sliding groove 112 , which means that the length of the stopping rod 322 is greater than the maximum width of the sliding groove 112 .

[0068] This arrangement can ensure that when the stop rod 322 slides to any position of the sliding groove 112, the stop rod 322 can be engaged with the sliding groove 112, that is, when the stop rod 322 slides to any position of the sliding groove 112, the portion of the stop rod 322 that exceeds the groove width of the sliding groove 112 can be stopped on the side wall of the sliding groove 112, preventing the stop rod 322 from slipping out of the sliding groove 112, thereby further improving the engagement stability of the second connecting part 320 and the first connecting part 110.

[0069] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the tank body 200 is provided with a limiting groove 210 , which can be recessed in the outer peripheral surface of the tank body 200 , the limiting groove 210 extends along the circumference of the tank body 200 , and at least a portion of the adjustment strap 310 is located in the limiting groove 210 .

[0070] That is to say, the limiting groove 210 can extend to the bottom surface of the tank body 200 and the opposite sides in the width direction of the tank body 200. In this way, at least a portion of the adjusting strap 310 can be set in the limiting groove 210, or the entire adjusting strap 310 can be set in the limiting groove 210. The opposite side walls of the limiting groove 210 can limit the adjusting strap 310 in the length direction of the tank body 200, thereby preventing the adjusting strap 310 from moving along the length direction of the tank body 200. The relative position fixation of the adjusting strap 310 and the tank body 200 is more stably and reliably fixed, further improving the fixing stability of the tank body 200.

[0071] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, there are multiple drawstring assemblies 300, and the multiple drawstring assemblies 300 are parallel to each other and arranged at intervals.

[0072] Specifically, multiple strap assemblies 300 can be arranged at intervals along the length direction of the tank body 200, so as to avoid position interference between adjacent strap assemblies 300, and multiple strap assemblies 300 can evenly distribute the force of the weight of the tank body 200, which can not only improve the reliability of fixing the strap assembly 300 to the tank body 200, but also extend the service life of the strap assembly 300, so as to make the connection between the tank body 200 and the battery frame 100 more stable and reliable.

[0073] Furthermore, in some other embodiments, a plurality of drawstring assemblies 300 may also be cross-arranged.

[0074] In some specific embodiments of the present invention, Figure 2 and Figure 5 As shown, the adjustment strap 310 includes a first strap 311 , a second strap 313 and an adjustment connector 315 .

[0075] A first connecting portion 110 is provided at one end of the first drawstring 311 and a first adjusting portion 312 is provided at the other end. A first connecting portion 110 is provided at one end of the second drawstring 313 and a second adjusting portion 314 is provided at the other end. An adjusting connector 315 is respectively connected to the first adjusting portion 312 and the second adjusting portion 314. The adjusting connector 315 can adjust the distance between the first adjusting portion 312 and the second adjusting portion 314 to adjust the length of the adjusting drawstring 310.

[0076] For example, the adjusting connector 315 can be a bolt, the first adjusting portion 312 and the second adjusting portion 314 can be set as bolt holes, the first pull strap 311 and the second pull strap 313 can be connected via the adjusting connector 315, and by adjusting the tightening degree of the adjusting connector 315, the distance between one end of the first pull strap 311 and one end of the second pull strap 313 can be adjusted, and then the overall length of the pull strap assembly 300 can be adjusted, so that after the two ends of the pull strap assembly 300 are connected to the battery frame 100, the pull strap assembly 300 can tighten the tank body 200, and the fixation of the tank body 200 is more reliable.

[0077] In addition, the total length of the adjusting strap 310 is adjusted by providing an adjusting connector 315 , so that the adjusting strap 310 can fix can bodies 200 of different specifications and sizes, thereby improving the versatility of the adjusting strap 310 .

[0078] Moreover, when it is necessary to separate the tank body 200 from the battery frame 100, the length of the drawstring 310 can be adjusted by adjusting the connecting piece 315 first, so that the operator can separate the second connecting part 320 and the first connecting part 110, that is, the drawstring assembly 300 can be separated from the battery frame 100, so that the tank body 200 can be removed from the battery frame 100, which makes disassembly and assembly more convenient and more efficient.
