[0003] Traditional electric vehicle frames often suffer from poor battery heat dissipation due to the separation between the battery and the battery charger. Furthermore, considering that separating the overall charging and discharging areas is safer, it is necessary to design a block-type structure that can ensure the separation of the charging and discharging areas. This solves the problem of the traditional electric vehicle frame bottom being designed with the charger and battery together, which is dangerous in summer, and the complex integrated circuit wiring that is intertwined and prone to short circuits. Utility Model Content

[0004] This utility model provides an electric vehicle frame with a separate charging and energy storage area, which aims to solve the problem that traditional electric vehicle frames often have poor battery heat dissipation due to the separation between the battery and the battery charger. In addition, considering that separating the overall charging and discharging areas is safer, it is necessary to design a block structure that can ensure the separation of the charging and discharging areas, thus solving the problem that the bottom of traditional electric vehicle frames is relatively dangerous in summer because the charger and battery are designed together for charging.

[0005] To achieve the above objectives, this utility model provides an electric vehicle frame with a charging and energy storage partition structure, including a charging partition and an energy storage partition;

[0006] The charging zone includes a rear frame, with a vertical support pole at the top center of the rear frame, a charger mounting tray at the top center of the rear frame, a controller at the center of the charger mounting tray, a charger mounted on the side of the controller, a converter electrically mounted on the side wall of the charger, a connecting bracket mounted on the back of the converter, a connecting crossbar horizontally mounted in the center of the connecting bracket, a U-shaped bracket mounted on the back of the connecting crossbar, outer frames mounted on both sides of the U-shaped bracket, and an I-shaped side wall bracket at the center of the side wall of the outer frame.

[0027] Please see Figures 1-5 This utility model provides an electric vehicle frame with a charging and energy storage partition structure, including a charging partition 1 and an energy storage partition 2;

[0028] Charging zone 1 includes a rear frame 11. A support pole 12 is vertically installed at the top center of the rear frame 11. A charger mounting tray 13 is installed at the top center of the rear frame 11. A controller 14 is installed in the center of the charger mounting tray 13. A charger 15 is installed on the side of the controller 14. A converter 16 is electrically installed on the side wall of the charger 15. A connecting bracket 17 is installed on the back of the converter 16. A connecting crossbar 18 is horizontally installed in the center of the connecting bracket 17. A U-shaped bracket 19 is installed on the back of the connecting crossbar 18. An outer frame 191 is installed on each side of the U-shaped bracket 19. An I-shaped side wall bracket 192 is provided in the center of the side wall of the outer frame 191.

[0029] In this embodiment: the power storage partition 2 includes a chassis suspension 21 installed at the other end of the I-shaped side wall frame 192, a roof frame 22 is installed at the end of the chassis suspension 21, and an arc-shaped frame 23 is installed at the top center of the roof frame 22.

[0030] The battery storage compartment 2 and chassis suspension 21 are used to house the battery, and the arc-shaped frame 23 is used to support the frame structure.

[0031] In this embodiment: a battery placement chassis 24 is installed on the bottom side of the vehicle chassis suspension 21. Safety beams 25 are provided on both sides of the battery placement chassis 24. A U-shaped binding frame 26 is installed laterally in the middle of the safety beam 25. Side wall trusses 27 are installed laterally on both sides of the U-shaped binding frame 26.

[0032] The battery is placed on the chassis 24, and one end of the safety beam 25 serves as the edge of the battery pack 28 to ensure the battery body is properly positioned and avoids bumps.

[0033] In this embodiment: a battery pack 28 is installed on the side wall of the battery placement chassis 24, a battery box 29 is installed horizontally in the middle of the battery pack 28, a vertical support rod 291 is installed vertically in the middle of the beam end of the safety beam 25, and a vehicle front mechanism 3 is installed horizontally on the side wall of the vertical support rod 291.

[0034] The battery pack 28 and battery box 29 are assembled on the vertical support rod 291 at one end of the box body.

[0035] In this embodiment: the front mechanism 3 includes a front suspension beam 31 installed on the side wall of the vertical support rod 291. A U-shaped bracket 32 ​​is installed at the middle of the bottom end of the front suspension beam 31. A fitting gasket 33 is installed horizontally at the middle of the top end of the U-shaped bracket 32. An I-shaped bracket 34 is vertically provided at the middle of the bottom end of the U-shaped bracket 32. A first L-shaped bracket 35 for connection is installed on the side of the I-shaped bracket 34. A support mechanism 4 is provided at the middle of the bottom end of the first L-shaped bracket 35.

[0036] The use of U-shaped bracket 32 ​​and I-shaped bracket 34 to share the load achieves the distribution of motion inertia of the front mechanism 3 during driving, making the front of the vehicle more stable during braking.

[0037] In this embodiment: a bottom frame 41 is horizontally installed at the middle of the bottom end of the support mechanism 4, a U-shaped frame 42 is horizontally installed at the end of the bottom frame 41, and a second L-shaped bracket 43 for transmission is installed on the bottom side of the U-shaped frame 42.

[0038] In this embodiment: a cockpit 36 ​​is provided laterally on the side of the I-shaped bracket 34, a driving truss 37 is installed on the side wall of the cockpit 36, a support bracket 38 is installed obliquely on the bottom side of the driving truss 37, and a rear wall bracket 39 is installed on the back of the support bracket 38.

[0039] The cockpit 36 ​​and cockpit 36 ​​cabin structure are used to house the battery and control unit circuits in the internal cavity. The space created by the rear wall bracket 39 is used to put the motor into the cavity, which can be classified and combined to avoid the battery being affected by the charger charging. In case of short circuit, it can effectively block the thermal conduction of the battery.

[0040] In this embodiment, the controller 14, charger 15 and converter 16 are all fixed to the surface of the corresponding mounting rod 392 by connecting screws 391.

[0041] The charger 15 and converter 16 are electrically connected at one end.

[0042] First step: Using the rear frame 11 as a base point, implement the adaptation and installation of the support pole 12;

[0043] The charging areas that require charging are assembled and installed together, and the controller 14, charger 15 and converter 16 are respectively arranged and installed on the charger installation tray 13 to guide the transfer between them.

[0044] By using the rods of the specific connecting bracket 17 as fulcrums, the corresponding U-shaped bracket 19 is integrated into an assembly. Through the outer frame 191 and the I-shaped side wall frame 192, the assembly of the rear end body of the electric vehicle forms a spatial cavity. During the electric vehicle's operation, there is a sufficient space to accommodate the charging area structure, and the power is transferred to the middle of the electric vehicle frame.

[0045] Step 2: Charging and powering the battery;

[0046] Personnel utilize one end of the side wall truss 27 to create space for the battery pack 28, placing it in the middle of the specific U-shaped binding frame 26. After the battery pack 28 is accommodated by the side wall truss 27, it is wrapped by the battery box 29. The weight is distributed according to the beam of the safety beam 25, and the battery placement chassis 24 serves as the bottom of the battery pack 28 for further weight distribution. At this point, an electrical connection is established with the rear charger 15, and an electrical connection is also achieved through one end of the converter 16. The weight distribution at the front of the vehicle is achieved through the support of the specific I-beam bracket 34. The U-shaped frame 42 serves as the vehicle's backbone support, and the space formed between it and the U-shaped bracket 32 ​​is used to house the front drive motor. When driving the vehicle, the space between the support bracket 38 and the central driver's cabin 36 allows for easy steering. In addition, the battery separation has the main advantage of ensuring faster heat dissipation of the integrated charger during summer charging, reducing short circuits during charging, and making the battery modules safer to use due to their reasonable arrangement. It also ensures that the charger is not exposed during charging, preventing electric shock due to conductivity and water contact when charging the electric vehicle.
