[0048] As shown in the background technology, in the prior art, the battery box is fixed to the beam of the heavy truck by screws. When replacing the battery, the staff needs to manually remove the screws connecting the battery box and the beam to remove the battery box with insufficient power, and then manually tighten the screws to install the fully charged battery box.

[0049] However, the above method of replacing the battery box is time-consuming and labor-intensive, and the replacement efficiency is low.

In this way, the replacement of the battery box is completed, the operation is convenient, and the replacement efficiency of the battery box is improved.

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0052] Reference Figures 1 to 3 As shown, the vehicle provided in the present application includes a vehicle frame 100 and a battery box 200 , and the battery box 200 has at least one connecting member 210 .

[0053] The frame 100 includes a frame body 110 and a locking assembly 120 arranged on the frame body 110. The frame body 110 has at least one mounting hole 111. The connecting piece 210 is inserted into the frame body 110 through the mounting hole 111. The locking assembly 120 is located between the frame body 110 and the battery box 200. The locking assembly 120 is used to fix or release the connecting piece 210.

[0054] The connector 210 is configured to abut or disengage with the locking assembly 120 when the locking assembly 120 moves toward or away from the mounting hole 111 to partially cover or fully open the mounting hole 111 , so as to lock or unlock the battery box 200 to the frame 100 .

[0055] It is understandable that at least one connector 210 and at least one mounting hole 111, that is, the number of connectors 210 and mounting holes 111 can be one or more, and the embodiment of the present application does not impose too many restrictions on this. It should be noted that the number of mounting holes 111 can also be more than the number of connectors 210, and the extra mounting holes 111 can be used as reserved mounting holes 111. By changing the size of the reserved mounting holes 111, battery boxes 200 of different sizes can be installed on the frame body 110; by changing the position of the reserved mounting holes 111, the battery box 200 can be installed at different positions of the frame body 110.

[0056] Reference Figure 1 and Figure 3As shown, by setting a connector 210 on the battery box 200 and setting a mounting hole 111 on the frame body 110, the connector 210 is inserted into the frame body 110 through the mounting hole 111 to achieve the connection between the battery box 200 and the frame body 110. The vehicle body is provided with a locking assembly 120, which is located between the frame body 110 and the battery box 200. Figure 2 As shown, when the locking assembly 120 covers a portion of the mounting hole 111 , the locking assembly 120 abuts against the connector 210 , so that the connector 210 cannot be pulled out of the mounting hole 111 , and the connector 210 and the locking assembly 120 jointly lock the battery box 200 to the frame 100 .

[0057] It should be noted that the above-mentioned locking method can independently realize the locking or unlocking of the battery box 200 and the frame 100; it can also be used in combination with other methods. For example, at least one connecting hole 112 and a connecting structure inserted in the connecting hole 112 can be provided on the frame body 110, and a locking piece is inserted on the battery box 200, and a part of the connecting structure is inserted in the battery box 200, so that the locking piece and the part of the connecting structure jointly lock the battery box 200 to the frame 100. The embodiments of the present application do not impose too many restrictions on this.

[0058] When disassembling the battery box 200 with low power, the locking assembly 120 covers part of the mounting hole 111 (refer to Figure 2 As shown), the locking assembly 120 is away from the mounting hole 111 ( Figure 2 (in the direction indicated by the arrow in the middle) to move the locking assembly 120 to fully open the mounting hole 111 (refer to Figure 1 As shown), the connector 210 is disengaged from the locking assembly 120, and the connector 210 is no longer restricted by the locking assembly 120. The connector 210 can be pulled out of the mounting hole 111, so that the battery box 200 is unlocked from the frame 100.

[0059] When installing the fully charged battery box 200, the locking assembly 120 fully opens the mounting hole 111 (refer to Figure 1 The connecting member 210 on the battery box 200 is inserted into the frame body 110 through the mounting hole 111. The locking assembly 120 is oriented toward the mounting hole 111 ( Figure 1 The locking assembly 120 covers part of the mounting hole 111 (refer to Figure 2 As shown in FIG. 1 , the locking assembly 120 abuts against the connecting member 210, and the connecting member 210 is restricted by the locking assembly 120, so that the connecting member 210 cannot be pulled out from the mounting hole 111, so that the connecting member 210 and the locking assembly 120 jointly lock the battery box 200 to the frame 100. Thus, the replacement of the battery box 200 is completed, the operation is convenient, and the replacement efficiency of the battery box 200 is improved.

[0060] In some embodiments, reference Figures 1 to 3 As shown, the connecting member 210 has an abutting portion 211 , and the abutting portion 211 is used to abut against or disengage from the locking assembly 120 .

[0061] It can be understood that by providing the abutting portion 211 on the connecting member 210, when the abutting portion 211 abuts against the locking assembly 120, the connecting member 210 cannot be pulled out from the mounting hole 111, and the connecting member 210 and the locking assembly 120 jointly lock the battery box 200 to the frame 100. When the abutting portion 211 is no longer abutted against the locking assembly 120, the connecting member 210 can be pulled out from the mounting hole 111, so that the battery box 200 is unlocked from the frame 100.

[0062] It should be noted that the shape of the abutment portion 211 can be a cube, a cuboid, a cone or a wedge, or other shapes, as long as the abutment portion 211 can be inserted into the frame body 110 through the mounting hole 111, and the embodiment of the present application does not impose too many restrictions on this.

[0063] In some embodiments, reference Figure 2 and Figure 3 As shown, there are at least two connecting members 210 , each of which is located on two opposite sides of the locking assembly 120 , and the abutting portions 211 are all facing the locking assembly 120 .

[0064] The number of the connecting members 210 is at least two. For example, there may be two connecting members 210, and the two connecting members 210 may be symmetrically distributed on opposite sides of the locking assembly 120; there may also be three connecting members 210, and the three connecting members 210 may be spaced apart on opposite sides of the locking assembly 120. Since the connecting members 210 are inserted into the mounting holes 111 one by one, the relative positions of the connecting members 210 may refer to Figure 1 The relative positions of the mounting holes 111 in the middle; the connecting members 210 may be more than three, and the embodiment of the present application does not impose too many restrictions on the number of connecting members 210.

[0065] It should be noted that the abutting portions 211 of the connecting members 210 are all facing the locking assembly 120. When the locking assembly 120 moves toward the mounting hole 111 to cover part of the mounting hole 111, the locking assembly 120 can respectively abut against the abutting portions 211 on both sides thereof, so that all the connecting members 210 and the locking assembly 120 can jointly lock the battery box 200 to the frame 100, which can effectively transmit and disperse the locking force, thereby enhancing the locking effect and ensuring the firmness of the connection between the battery box 200 and the frame 100.

[0066] In some embodiments, reference Figure 1As shown, the locking assembly 120 includes a locking member 121 and a moving member 122 . The locking member 121 is connected to the moving member 122 . The moving member 122 is used to drive the locking member 121 to move toward or away from the mounting hole 111 .

[0067] Specifically, the moving member 122 drives the locking member 121 toward the mounting hole 111 ( Figure 1 +X direction as indicated by the arrow in the middle) so that the locking member 121 covers part of the mounting hole 111 (refer to Figure 2 As shown), the locking member 121 abuts against the connecting member 210, and the connecting member 210 cannot be pulled out from the mounting hole 111. The connecting member 210 and the locking member 121 jointly realize the locking function.

[0068] The moving member 122 drives the locking member 121 away from the mounting hole 111 ( Figure 2 (in the direction indicated by the arrow in the middle) to move the locking member 121 to fully open the mounting hole 111 (refer to Figure 1 As shown), the locking member 121 is disengaged from the connecting member 210, and the connecting member 210 can be pulled out from the mounting hole 111, thereby unlocking the battery box 200.

[0069] In some embodiments, reference Figure 3 and Figure 4 As shown, the locking member 121 is provided with at least one avoidance groove 1211 for avoiding the connecting member 210 .

[0070] At least one avoidance groove 1211. Exemplarily, there can be one avoidance groove 1211 or more avoidance grooves 1211, as long as the number of avoidance grooves 1211 is consistent with the number of connectors 210. The embodiment of the present application does not impose too many restrictions on this.

[0071] It can be understood that by providing the avoidance groove 1211 on the locking member 121, referring to Figure 1 As shown, when the avoidance groove 1211 corresponds to the mounting hole 111 , the mounting hole 111 is fully opened, so that the connecting member 210 and the locking member 121 are disengaged from each other, the connecting member 210 can be pulled out from the mounting hole 111 , and the battery box 200 is unlocked from the frame 100 .

[0072] When the avoidance groove 1211 is staggered with the mounting hole 111, refer to Figure 2 As shown, the locking member 121 covers a portion of the mounting hole 111 , so that the connecting member 210 abuts against the locking member 121 , the connecting member 210 cannot be pulled out from the mounting hole 111 , and the battery box 200 is locked to the vehicle frame 100 .

[0073] In some embodiments, reference Figure 1 , Figure 2 and Figure 5As shown, the locking assembly 120 further includes a sleeve 123 , which is connected to the frame body 110 , and a portion of the moving member 122 is inserted into the sleeve 123 .

[0074] A partition plate 1221 is provided on the moving member 122 , and the partition plate 1221 divides the sleeve 123 into a first chamber 1231 and a second chamber 1232 .

[0075] The sleeve 123 has a first oil hole 1233 and a second oil hole 1234. The first oil hole 1233 is connected to the first chamber 1231, and hydraulic oil is injected into or flows out of the first chamber 1231 through the first oil hole 1233. The second oil hole 1234 is connected to the second chamber 1232, and hydraulic oil is injected into or flows out of the second chamber 1232 through the second oil hole 1234 to drive the moving part 122 and the locking part 121 to move toward or away from the mounting hole 111.

[0076] The sleeve 123 is connected to the frame body 110. For example, the sleeve 123 and the frame body 110 can be connected by screws or in other ways. The shape of the sleeve 123 can be a rectangular parallelepiped, a cube, a cylinder, or other shapes, and the embodiments of the present application do not impose too many restrictions on this.

[0077] Specifically, when hydraulic oil is injected into the second chamber 1232 through the second oil hole 1234, the pressure in the second chamber 1232 increases, so as to drive the partition plate 1221 to move away from the mounting hole 111, and the moving member 122 drives the locking member 121 to move away from the mounting hole 111. As a result, the volume of the second chamber 1232 increases, the volume of the first chamber 1231 decreases, and the hydraulic oil in the first chamber 1231 is discharged through the first oil hole 1233.

[0078] When hydraulic oil is injected into the first chamber 1231 through the first oil hole 1233, the pressure in the first chamber 1231 increases to drive the partition plate 1221 to move toward the mounting hole 111, and the moving member 122 drives the locking member 121 to move toward the mounting hole 111. As a result, the volume of the first chamber 1231 increases, the volume of the second chamber 1232 decreases, and the hydraulic oil in the second chamber 1232 is discharged through the second oil hole 1234.

[0079] In some embodiments, reference Figure 1 and Figure 5 As shown, the locking assembly 120 further includes at least one fastener 124 , and the fastener 124 connects the sleeve 123 and the frame body 110 .

[0080] It can be understood that the fastener 124 connects the sleeve 123 to the frame body 110 to ensure that they will not separate or loosen during use.

[0081] At least one fastener 124, that is, the number of fasteners 124 can be one or more. In a specific implementation, the fastener 124 can be a screw, a through hole is provided on the sleeve 123, a threaded hole is provided on the frame body 110, the screw is inserted into the threaded hole through the through hole, and the screw is connected to the threaded hole by threads, so that the sleeve 123 is fixed to the frame body 110.

[0082] In some embodiments, reference Figure 6 and Figure 7 As shown, the vehicle also includes a hydraulic system 300, which includes an oil storage tank 310, an oil pump 320, an oil pipe 330 and a first control valve 340. The oil pipe 330 connects the oil storage tank 310, the oil pump 320 and the first control valve 340, and the first control valve 340 is connected to the first oil hole 1233 and the second oil hole 1234 respectively through the oil pipe 330.

[0083] The first control valve 340 controls the oil pipe 330 to inject hydraulic oil into the first oil hole 1233 to drive the movable member 122 and the locking member 121 to move toward the mounting hole 111. The first control valve 340 controls the oil pipe 330 to inject hydraulic oil into the second oil hole 1234 to drive the movable member 122 and the locking member 121 to move away from the mounting hole 111.

[0084] It should be noted that the first control valve 340 may be an electric four-way valve, and the first control valve 340 may be electrically connected to a controller of the entire vehicle.

[0085] Reference Figure 6 As shown, when disassembling the battery box 200 with low power, the vehicle controller controls the first control valve 340, conducts the hydraulic oil from the oil pump 320 to the circuit of the second chamber 1232, conducts the hydraulic oil from the first chamber 1231 to the circuit of the oil storage tank 310, and controls the hydraulic oil pump 320 to start working, the hydraulic oil is drawn out from the oil storage tank 310 and flows into the second chamber 1232, and at the same time, the space of the first chamber 1231 is compressed, the hydraulic oil in the first chamber 1231 is squeezed and flows into the oil storage tank 310, and the partition plate 1221 begins to move away from the mounting hole 111 ( Figure 2 As the oil pump 320 continues to work, the partition plate 1221 drives the moving member 122 and the locking member 121 to continuously move away from the mounting hole 111 until the locking member 121 completely opens the mounting hole 111 (refer to Figure 1 As shown), the locking member 121 is disengaged from the connection member 210, and the connection member 210 can be pulled out from the mounting hole 111, and the battery box 200 is unlocked from the frame 100.

[0086] Reference Figure 7As shown, when the fully charged battery box 200 is installed, the connector 210 on the battery box 200 is inserted into the frame body 110 through the mounting hole 111. The vehicle controller controls the first control valve 340 to conduct the hydraulic oil from the oil pump 320 into the first chamber 1231, and conducts the hydraulic oil from the second chamber 1232 into the oil tank 310. The oil pump 320 continues to work, and the partition plate 1221 begins to move toward the mounting hole 111 ( Figure 1 As the oil pump 320 continues to work, the partition plate 1221 drives the moving member 122 and the locking member 121 to continue to move toward the mounting hole 111 until the locking member 121 covers a portion of the mounting hole 111 (refer to Figure 2 As shown), the locking member 121 abuts against the connecting member 210, and the connecting member 210 cannot be pulled out from the mounting hole 111. The connecting member 210 and the locking member 121 jointly lock the battery box 200 to the frame 100.

[0087] It should also be noted that a one-way valve 360 ​​may be provided on the oil pipe 330 to control the flow of hydraulic oil in a fixed direction to prevent the hydraulic oil from flowing back and affecting the locking angle or locking force. An oil pressure sensor may also be provided on the oil pipe 330. On the one hand, the oil pressure sensor can be used to detect the oil pressure condition in the hydraulic system 300. When the oil pressure sensor detects that the pressure value reaches the target value, it means that the battery box 200 has been tightened and the oil pump 320 has been turned off. On the other hand, when the hydraulic oil leaks, the driver or staff can be notified in time to reduce the possibility of the hydraulic system 300 failure affecting the battery replacement.
