[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: Please refer to Figures 1 to 6 :

[0030] The utility model provides a new energy vehicle battery pack that is convenient to replace, including: a main battery pack module 1, an external connection frame 2, and side limit connection blocks 3. On both sides of the main battery pack module 1, external connection blocks 101 are welded and arranged at intervals in an array. A concave side connection slot 102 is formed on the side surface of the external connection block 101, and a middle connection slot 103 is recessed on the side surface of the external connection block 101. Lower connection bolt holes 104 are formed in the middle connection slots 103 of the outermost external connection blocks 101 on both sides of the main battery pack module 1. External connection frames 2 are attached to both sides of the main battery pack module 1. Lower connection support blocks 201 are welded at intervals in the lower part of the inner side of the external connection frame 2. Side connection blocks 202 penetrate and slide in the middle of the external connection frame 2. A rear guiding inclined slot 203 is formed at the tail of the side connection block 202. The external connection block 101 is located above the main battery pack module 1. The top of the external connection block 101 and the lower connection support block 201 are in sliding contact. The side surface of the external connection frame 2 and the side surface of the lower connection support block 201 are in sliding contact. The side surface of the external connection block 101 and the side surface of the main battery pack module 1 are in sliding contact. Side limit connection blocks 3 penetrate and slide vertically in the middle of the external connection frame 2.

[0031] In the embodiment of the present disclosure, the interval distance between the lower connection support blocks 201 is greater than the width of the external connection block 101. The head end of the side connection block 202 is slidably inserted into the side connection slot 102. The middle part of the external connection block 101 is restricted from moving horizontally. The fixing screw 303 penetrates through the lower connection support block 201, dispersing the pressure borne by the fixing screw 303 and reducing the number of fixing screws 303 to ensure firmness.

[0032] In the embodiment of the present disclosure, the tail end of the side limit connection block 3 is fixedly connected to the middle connecting rod 301. A plurality of side limit connection blocks 3 are connected to the middle connecting rod 301 at intervals. An upper sliding groove connection frame 302 is welded and fixed to the top of the middle connecting rod 301. Fixing screws 303 are rotated on the side limit connection blocks 3 at the outermost edges on both sides of the main battery pack module 1. The fixing screws 303 are screwed into the lower connection bolt holes 104. Four fixing screws 303 are screwed into the lower connection bolt holes 104 to fix the external connection block 101, eliminating the need for the middle fixing screw 303, reducing the number of fixing screws 303, and improving the replacement and installation speed of the main battery pack module 1.

[0033] In the embodiment of the present disclosure, the upper chute connecting frame 302 is slidably connected to the rear guiding chute 203. The upper chute connecting frame 302 is guided by the rear guiding chute 203 to horizontally move the side connecting block 202. The head end of the side connecting block 202 is slidably inserted into the side connecting slot 102. The side limiting connecting block 3 is vertically slidably connected to the lower connecting support block 201. The middle connecting rod 301 is vertically slidably connected to the outer connecting frame 2. The side limiting connecting block 3 is slidably inserted into the middle connecting slot 103. Multiple side limiting connecting blocks 3 are slidably inserted into the middle connecting slot 103, realizing the connection and fixing operation between the main battery pack module 1 and the outer connecting frame 2, dispersing the pressure borne by the fixing screws 303, and reducing the number of fixing screws 303 to ensure firmness.

[0034] Embodiment 2: On the basis of Embodiment 1, the fixing screws 303 of the side limiting connecting block 3 are no longer provided. The fixing screws 303 are screwed to the outer connecting frame 2. The upper end of the fixing screw 303 contacts the middle connecting rod 301. While the middle connecting rod 301 rotates, it axially moves to push the middle connecting rod 301 upward. The middle connecting rod 301 and the side limiting connecting block 3 move upward synchronously, realizing the sliding insertion of multiple side limiting connecting blocks 3 of the middle connecting rod 301 into the middle connecting slot 103, realizing the connection and fixing operation between the main battery pack module 1 and the outer connecting frame 2, and reducing the fixing screws 303 to two, further reducing the number of fixing screws 303, accelerating the installation speed, and improving the installation efficiency.

[0035] The working principle of this embodiment: The outer connecting frame 2 is welded or bolt-fixed to the vehicle body. The lifting device lifts the main battery pack module 1 and moves it upward. The outer connecting block 101 vertically moves upward along the interval of the lower connecting support block 201, and then the outer connecting block 101 horizontally moves and slides to the top of the lower connecting support block 201. The lower connecting support block 201 supports the outer connecting block 101 and the main battery pack module 1, realizing the connection and positioning operation of the main battery pack module 1. Then, four fixing screws 303 are screwed to the lower connecting bolt holes 104 to fix the outer connecting block 101, eliminating the setting of the middle fixing screws 303, reducing the number of fixing screws 303, improving the replacement and installation speed of the main battery pack module 1. During the process of screwing and fixing the fixing screws 303, it is not necessary to lift and support the main battery pack module 1. The lifting device can be used for other vehicles, reducing the occupation time of the lifting equipment;

[0036] During the screwing process of the fixing screw 303 and the lower connecting bolt hole 104, the fixing screw 303 and the side limit connection block 3 move upward synchronously. The side limit connection block 3 and the middle connecting rod 301 move upward synchronously. The side limit connection block 3 moves upward and is slidably inserted into the upper middle connection slot 103. The middle connecting rod 301 and the upper chute connection frame 302 move upward synchronously. The upper chute connection frame 302 guides the horizontal movement of the side connection block 202 through the rear guiding chute 203. The front end of the side connection block 202 is slidably inserted into the side connection slot 102. The middle part and both sides of the outer connection block 101 are restricted, dispersing the pressure borne by the fixing screw 303, reducing the number of fixing screws 303 to ensure firmness, and further enhancing the firmness between the main battery pack module 1 and the outer connection frame 2.
