[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0025] Example 1:
[0026] like Figure 1-Figure 3 As shown, a CTC body frame that facilitates inverted battery arrangement includes a lower body 100, and L-shaped mounting grooves 101 that are connected to each other are provided at the left and right ends of the lower body 100, and one side of the L-shaped mounting groove 101 is connected to the lower end of the lower body 100, a battery pack 102 is installed inside the L-shaped mounting groove 101, and a sliding assembly is provided between the battery pack 102 and the bottom of the L-shaped mounting groove 101, side fenders 103 are bolted to the left and right ends of the lower body 100, and the two side fenders 103 are respectively abutted against the left and right ends of the battery pack 102, and a bottom guard plate 104 is installed at the lower end of the lower body 100, and the bottom guard plate 104 is tightly abutted against the lower body 100 and the lower ends of the two side fenders 103.
[0027] The lower body 100 is one of the important components of the car. The L-shaped mounting groove 101 not only makes it convenient for the staff to quickly install or replace the battery pack 102, but also allows the battery pack 102 to be installed in an inverted manner, which can increase the safety of the car. The two side guards 103 abut the left and right ends of the battery pack 102 to ensure that it is always in the middle position of the L-shaped mounting groove, which facilitates the subsequent connection of the battery pack 102. The lower end of the side guard 103 is also provided with a pulling groove. After the connection between the side guard 103 and the lower body 100 is released, the side guard 103 can be better removed. The bottom guard plate 104 can protect the bottom of the lower body 100 and also protect the part of the battery pack 102 protruding from the lower end of the lower body 100.
[0028] When the battery pack 102 needs to be replaced: first, remove the bottom guard plate 104, then release the lock between the two side guard plates 103 and the lower body 100, and then use the lifting slot to remove the side guard plates 103. Finally, push the battery pack 102 from the slot on either side of the L-shaped mounting slot 101. Since the sliding assembly reduces the friction between the battery pack 102 and the bottom of the L-shaped mounting slot 101, the battery pack 102 can slide out of the L-shaped mounting slot 101 more quickly, so that the staff can use the lift to catch the battery pack 102 and replace the battery pack 102.
[0029] In this embodiment, an L-shaped mounting groove 101 is provided inside the lower vehicle body 100 so that the installed battery pack 102 is integrated with the lower vehicle body 100. This reduces the space occupied by the battery pack 102 inside the vehicle. The L-shaped mounting groove 101 places the installed battery pack 102 in an inverted state. In the event of a fire in the vehicle, this increases the time for people inside the vehicle to escape and improves the safety of the vehicle.
[0030] Example 2:
[0031] like Figures 1-4 As shown, based on the first embodiment, other components on a CTC body frame that facilitates the inverted arrangement of the battery are further described. The sliding assembly includes two horizontal bars 200, which are symmetrically fixedly connected to the lower ends of the battery pack 102. A slide groove 201 is provided at the lower end of the two horizontal bars 200, and a plurality of balls 202 matching the slide groove 201 are provided at the bottom of the L-shaped mounting groove 101.
[0032] A groove 203 is defined at the bottom of the L-shaped installation slot 101 , and a plurality of through slots 204 are defined at the bottom of the groove 203 .
[0033] A plurality of heat dissipation fins 205 are fixed to the lower end of the lower body 100 , and the heat dissipation fins 205 are arranged alternately with the through slots 204 in each row.
[0034] The front and rear ends of the bottom guard plate 104 are both arranged to be inclined, and the front and rear inclined surfaces are both arranged to be filter mesh-shaped.
[0035] A plurality of cross bars 206 are provided at the upper end of the lower body 100 .
[0036] In this embodiment, the groove 203 increases the distance between the battery pack 102 and the bottom of the L-shaped mounting groove 101, so that the respective relief valves provided at the lower end of the L-shaped mounting groove 101 and corresponding to the respective through grooves 204 can regulate the pressure inside the battery pack 102. When the internal pressure of the battery pack 102 rises to a preset safety critical value, the relief valve will automatically open to release part of the pressure to prevent the battery system inside the battery pack 102 from being damaged due to excessive pressure. This can protect the integrity of the battery pack 102 and extend the service life of the battery pack 102. The respective through grooves 204 are mainly used for heat dissipation, and can also discharge the gas discharged by the relief valve.
[0037] When the car is driving, the inclined surface on the front side of the bottom guard plate 104 allows air to flow in and out from the inclined surface on the rear side of the bottom guard plate 104. In this way, when the air flows through the inside of the bottom guard plate 104, the flowing air will take away the heat on the surface of each cooling fin 205, thereby lowering the temperature around the battery pack 102 and reducing damage to the battery pack 102. In addition, the inclined surface is not easy to accumulate dust and affect the air circulation.
[0038] Each cross bar 206 can strengthen the lateral strength of the lower vehicle body 100, and can indirectly protect the battery pack 102 from excessive damage and accidents in the event of a side collision.
[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
