As the most important energy storage component of new energy vehicles, the battery pack is generally fixedly installed in a box for protection, and then the box with the battery pack is fixedly installed on the vehicle body.

[0003] Publication No.: CN216698605U, discloses: a mounting frame fixing structure for a new energy truck battery pack, which completes the fixed connection between the limit seat and the mounting frame body by threading three bolts on the upper end of the limit seat, thereby improving the stability of the battery pack body, and at the same time, by pushing the fixed round block, the sliding rod and the two limit blocks are inserted into the circumferential inner wall of the rotating groove, so that the fixed round block is rotated to drive the two limit blocks to rotate, so that the two limit blocks slide into the inner wall of the limit groove, and the installation and fixation of the two mounting frame bodies are completed. The fixed installation structure is simple and convenient, and the work efficiency of installation and disassembly is improved. It is necessary to first use multiple bolts, limit seats and support plates to fix the battery pack in the mounting frame body located on the lower side, and then use multiple sets of clamping mechanisms to fix the two mounting frame bodies. As a result, when taking and placing the battery pack, the staff needs to operate multiple bolts and multiple sets of clamping mechanisms one by one, which is relatively cumbersome and inconvenient for the installation and replacement of the battery pack.

Two clamping blocks 8 are relatively fixed on the bottom of the movable plate 7 and cooperate with the battery pack body 3. A through hole 9 is provided on the fixing plate 5. A positioning groove 10 is provided on the inner wall of the guide groove 4. Support rods 12 are fixed on the lower sides of the mutually adjacent sides of the two fixing plates 5. Elastic parts are provided on the support rods 12. A wedge block 14 is fixed on the elastic part. A positioning rod 15 is fixed on one side of the wedge block 14 and cooperates with the through hole 9 and the positioning groove 10. An extrusion block 11 is fixed on the clamping block 8 through a connecting rod and cooperates with the inclined surface of the wedge block 14.

[0025] The locking cam 14 is engaged with the locking cam 16 and the locking cam 17, and the locking cam 18 is engaged with the locking cam 16, so that the locking cam 16 is engaged with the locking cam 17.

[0026] The elastic member includes a guide plate 13, a limit block 16 and a spring 17. The limit block 16 is fixed to the end of the support rod 12 away from the fixed plate 5. The guide plate 13 is slidably mounted on the support rod 12. The wedge block 14 is fixed to the upper end of the guide plate 13. The spring 17 is mounted on the outside of the support rod 12, and the two ends of the spring 17 are respectively connected to the guide plate 13 and the limit block 16.

[0027] The lower end of the screw rod 6 is rotatably connected to an upper pressure plate 18, and two guide rods 19 are fixed between the top of the upper pressure plate 18 and the movable door body 1. Two round holes are relatively penetrated on the movable plate 7, and the guide rods 19 pass through the round holes. The movable plate 7 and the guide rods 19 are movably matched.

[0028] A groove 20 is formed on the outer surface of the movable door body 1. A knob 21 is disposed inside the groove 20. The knob 21 is fixedly connected to the upper end of the rotating shaft.

[0029] A plurality of mounting blocks 22 are fixed to the bottom of the outer wall of the outer shell 2, and two notches are provided on the outer wall of the movable door body 1. The cross section of the clamping block 8 is an L-shaped structure. The mounting blocks 22 facilitate the installation and fixation of the outer shell 2, and the notches facilitate the operation of the movable door body 1.

[0030] A mounting groove 23 is fixed at the bottom of the inner cavity of the outer shell 2 , and the battery pack body 3 is embedded in the mounting groove 23 .

[0031] Example:

[0032] When in use, the battery pack body 3 is first inserted and installed in the installation groove 23, and then the fixing plate 5 is adjusted to align with the guide groove 4, and the movable door body 1 is adjusted to move toward the upper end of the outer shell 2 through the notch. As the movable door body 1 moves, the fixing plate 5 is driven to slide downward along the direction of the guide groove 4 until the upper pressing plate 18 is pressed on the top of the battery pack body 3;

[0033] Then, the knob 21 is turned, and the screw rod 6 is driven to rotate under the action of the rotating shaft. Combined with the threaded cooperation between the movable plate 7 and the screw rod 6, and the movable cooperation between the movable plate 7 and the guide rod 19, the movable plate 7 is driven to move downward stably until the clamping block 8 is abutted against the battery pack body 3, and the battery pack body 3 is limitedly clamped, thereby ensuring the stability of the battery pack body 3;

[0034] In the process of adjusting the movable plate 7 to move downward, under the action of the connecting rod, the extrusion block 11 is driven to move downward synchronously. Combined with the mutual cooperation between the extrusion block 11 and the inclined surface of the wedge block 14, and the sliding cooperation between the guide plate 13 and the support rod 12, as the extrusion block 11 moves downward, the wedge block 14 is squeezed in the direction close to the fixed plate 5, and the spring 17 is stretched at the same time. When the movable plate 7 drives the clamping block 8 to abut against the battery pack body 3, under the action of the wedge block 14, the positioning rod 15 is driven to pass through the corresponding through hole 9 and inserted into the corresponding positioning groove 10, so that the fixed plate 5 is connected with the outer shell 2, and then the movable door body 1 is connected with the outer shell 2, without the need to fix them with bolts;

[0035] When disassembling the movable door body 1, it is only necessary to rotate the knob 21 in the opposite direction. Under the action of the screw 6, the movable plate 7 is adjusted to move upward, driving the clamping block 8 up and down to disengage from the limiting clamping of the battery pack body 3, and at the same time driving the extrusion block 11 upward away from the wedge block 14. Under the elastic action of the spring 17, combined with the guide plate 13, the wedge block 14 is driven to return to its initial position, and then the positioning rod 15 is driven to disengage from the corresponding positioning groove 10, which facilitates the rapid separation of the movable door body 1 and the outer shell 2, and then facilitates the removal and placement of the internal battery pack body 3, and facilitates the installation, fixation, removal and replacement of the battery pack.

[0036] Compared with the prior art, the utility model limits and clamps the battery pack body 3 by adjusting the clamping block 8. At the same time, with the cooperation of the extrusion block 11 and the wedge block 14, the positioning rod 15 passes through the corresponding through hole 9 and is pressed into the corresponding positioning groove 10, thereby realizing the connection and fixation between the movable door body 1 and the outer shell 2. There is no need to use bolts to fix the battery pack, nor is there any need to use bolts to connect and fix the movable door body 1 and the outer shell 2, which facilitates the installation process of the battery pack and the removal and placement during later disassembly and replacement.
