[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Combined with Figure 1-6In order to solve the above technical problems, the technical solution provided by the utility model is: a battery pack fastening device, including a panel 1. The panel 1 carries all parts. A plurality of through holes 3 are connected inside the panel 1, which are the positions where the crossbeam 2 is assembled in the panel 1. A plurality of crossbeams 2 matching the through holes 3 are connected inside the panel 1 for bolt guide installation. A limiting ring 4 is connected at one end of the crossbeam 2, and a plurality of card slots 5 matching the limiting ring 4 are connected at one side of the panel 1. The mutual cooperation between the limiting ring 4 and the card slot 5 makes it easy to fix the installation position of the crossbeam 2 in the through hole 3 of the panel 1.

[0020] The panel 1 is provided with connecting parts 19 at both ends, which are the parts where the panel 1 is connected to the insert 6. The connecting part 19 is connected with a mounting groove 7 on the side away from the panel 1, which is a place for installing the insert 6. The panel 1 is provided with inserts 6 matching the mounting groove 7 at both ends, and the insert 6 is used to support bolt locking. The connecting part 19 is located in the mounting groove 7 and is connected with a No. 1 clamping block 8. The bottom end of the insert 6 is connected with a No. 1 positioning groove 9 matching the No. 1 clamping block 8. The No. 1 clamping block 8 and the No. 1 positioning groove 9 are mainly used for aligning the insert 6 with the connecting part 19. The connecting part 19 is located on both sides of the No. 1 clamping block 8 and is connected with a No. 2 clamping block 10 close to one end of the panel 1. The bottom end of the insert 6 is connected to one side of the panel 1 with a plurality of No. 2 positioning grooves 11 that cooperate with the No. 2 clamping block 10. The No. 2 clamping block 10 and the No. 2 positioning grooves 11 are used to assist the insert 6 in aligning the position for installation, and also assist the insert 6 in sliding out of the installation groove 7 in the direction away from the panel 1. The connecting portion 19 is located on both sides of the No. 1 clamping block 8 and is connected to limit columns 12 away from the panel 1. The bottom of the insert 6 away from the panel 1 is connected to a plurality of limit grooves 13 that cooperate with the limit columns 12, which are mainly used to prevent the insert 6 from sliding out of the installation groove 7 in the direction away from the panel 1. The insert 6 is fixed to one end of the panel 1 by semi-engaging and limiting. The connecting portion 19 is located at the No. 2 clamping block 8. A No. 1 threaded hole 14 is connected between the block 10 and the limiting column 12, and a plurality of No. 2 threaded holes 15 are connected in the insert 6 to match the No. 1 threaded hole 14 for matching bolt operation. The top of the No. 1 threaded hole 14 is tightly fitted with the bottom of the No. 2 threaded hole 15, so that the bolts passing through the No. 1 threaded hole 14 and the No. 2 threaded hole 15 can be more tightly matched with the insert 6 and the connecting part 19 of the panel 1. A groove 17 matching the No. 2 threaded hole 15 is connected to the top of the connecting part 19 away from the end of the panel 1, which is convenient for the placement of the protruding part of the bolt head so that it will not protrude from the surface of the panel 1 and affect the installation and aesthetics of the battery pack. A shoulder block 18 is connected to the top of the connecting part 19 near the panel 1, which is used to close and support the edge of the panel 1 of the connecting part 19. Fastening blocks 16 that cooperate with the connecting part 19 are connected to both ends of the insert 6, which are used to fill the gap between the two sides of the insert 6 and the panel 1, so that the insert 6 is more firmly fixed on the panel 1. Except for the necessary grooves and holes, the interior of the insert 6 is a solid setting, so that when the insert 6 is installed in the mounting groove 7 of the connecting part 19, all adjacent areas of the insert 6 and the connecting part 19 are contact-type solid settings, which can enhance the mechanical strength of the connection method and the components, and the interior of the insert 6 is a hollow setting, which reduces the weight of the device.

[0021] When the utility model is implemented in detail, when installing the device, first insert the cross beams 2 into the corresponding through holes 3 on the panel 1 one by one. Due to the existence of the limiting ring 4, the cross beam 2 can only be inserted from the end away from the limiting ring 4, but it should be noted that the cross beam 2 needs to be inserted from the side of the panel 1 with the card slot 5. After insertion, the limiting ring 4 on the cross beam 2 is just snapped into the card slot 5, and the above two are fixed by welding. Then, the two inserts 6 are respectively installed in the installation grooves 7 on both sides of the panel 1. During installation, the No. 1 positioning groove 9 and the No. 2 positioning groove 11 in the bottom of the insert 6 are aligned with the No. 1 card block 8 and the No. 2 card block 10 on the connecting part 19 of the panel 1 and inserted from top to bottom. After insertion, the two limiting columns 12 on the connecting part 19 are also just snapped into each other with the limiting groove 13 on the insert 6, and no conflict occurs. After installation, the connecting part The two No. 1 threaded holes 14 on 19 and the No. 2 threaded hole 15 on the insert 6 are also in a coaxial state. Because after installation and engagement, the insert 6 is in a state where each adjacent portion is wrapped around the connecting portion 19. Due to the different shapes, the insert 6 will not be installed upside down on the panel 1 during the installation process, thereby avoiding the embarrassment of being welded and fixed on the panel 1 and unable to be removed after being installed upside down. In addition, due to the design of the insert 6 and the existence of the internal hollow setting, the functional mechanical strength of the device can be enhanced. After installation, the insert 6 can be reinforced on the panel 1 by welding, and the installation process is relatively simple. Due to the setting and installation of the above-mentioned components of the device, it is possible to effectively deal with the risk of deformation caused by battery expansion thereby affecting the fastener when the battery pack fastening device is used to carry the battery.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
