Description

Technical Field

[0001] This utility model relates to the field of vehicle charging technology, and more specifically, to a battery frame, a battery module, and a battery box. Background Technology

[0002] In current battery box designs, the battery frame typically includes main structural components such as a base plate, side plates, and a cover plate, which together form the basic unit for accommodating and protecting the battery module. When power demand is high, multiple battery frames can be stacked along the height direction to form a battery box, increasing the power supply capacity of the battery box. The stacked battery frames are fixed by connectors (such as bolts, long screws, etc.) located at their four corners, forming a rigid integral battery box. Patent document CN216488342U discloses a box, battery, and power supply device. The box is used to accommodate individual battery cells and includes: a positioning component, including a bottom wall and side walls connected to the periphery of the bottom wall, the side walls and the bottom wall enclosing a positioning cavity, and the bottom wall having a hollowed-out portion; a fixing frame, located in the positioning cavity and used to enclose the individual battery cells; and a bottom protective plate, disposed on the side of the bottom wall opposite to the positioning cavity.

[0003] However, during vehicle operation, the battery frame is continuously subjected to lateral forces along its width due to factors such as road bumps, centrifugal force during steering, and impacts from sudden braking. Because existing stacked structures primarily rely on their own weight and simple vertical restraints to maintain relative position, lacking effective constraints in the width direction, adjacent battery frames are prone to relative sliding along the width under repeated lateral force impacts. This sliding gradually accumulates with the continuous application of load, eventually leading to a significant relative positional shift, endangering the integrity of the battery pack structure and vehicle driving safety.

[0035] In existing battery boxes, the battery frame consists of a bottom side unit 11, a first side unit 13, a second side unit 14, and two third side units 15. Multiple battery frames are stacked vertically to supply power to the vehicle. However, during battery box transportation, when subjected to lateral force impact along the width direction, there is a lack of sufficient constraint mechanism between the battery frames, which makes it easy for adjacent battery frames to slide relative to each other, thus causing insufficient overall stability of the battery box.

[0036] Example 1:

[0037] This embodiment discloses a battery frame, such as Figure 1 As shown, the battery frame includes a frame component 10.

[0038] The frame assembly 10 includes a bottom side unit 11, a first side unit 13, a second side unit 14, and two third side units 15. Preferably, the frame assembly 10 is made of aluminum alloy, which reduces the weight of the frame assembly 10 and decreases the load on the vehicle.

[0039] like Figure 4 As shown, the first side unit 13 includes a first side plate 131, a first upper inclined portion 132, and a first lower inclined portion 133. The second side unit 14 includes a second side plate 141, a second upper inclined portion 142, and a second lower inclined portion 143. The first side plate 131, one third side unit 15, the second side plate 141, and another third side unit 15 are sequentially connected to form a ring. The bottom side unit 11 is disposed on one side of the ring, forming a hollow cavity with an opening on one side, providing space for components such as the battery pack 24. The first upper inclined portion 132 and the first lower inclined portion 133 are respectively connected to the opposite sides of the first side plate 131 to facilitate cooperation with other components. The first upper inclined portion 132 and the first lower inclined portion 133 are respectively disposed on the two sides of the ring. The inclined surface of the first lower inclined portion 133 is parallel to the inclined surface of the first upper inclined portion 132. The minimum included angle between the inclined surface of the first upper inclined portion 132 and the set plane 16 is less than 90° (e.g., Figure 8 As shown in α), it provides a structural foundation for the inclined part to bear lateral forces.

[0040] The second upper inclined portion 142 and the second lower inclined portion 143 are respectively connected to the two opposing sides of the second side plate 141. The second upper inclined portion 142 and the second lower inclined portion 143 are respectively provided on both sides of the annular shape. The inclined surface of the second lower inclined portion 143 is parallel to the inclined surface of the second upper inclined portion 142. The minimum included angle between the inclined surface of the second upper inclined portion 142 and the set plane 16 is less than 90° (e.g., Figure 8 As shown in β), it provides a structural foundation for the inclined part to bear lateral forces.

[0041] like Figure 4 As shown, the inclined surface of the first upper inclined portion 132 extends in the opposite direction to the inclined surface of the second upper inclined portion 142. This opposite extension direction allows the first upper inclined portion 132 and the second upper inclined portion 142 to resist lateral forces from opposite directions. Simultaneously, the trapezoidal abutment structure formed by the first upper inclined portion 132 and the second upper inclined portion 142, and the trapezoidal abutment structure formed by the first lower inclined portion 133 and the second lower inclined portion 143, ensures that when the battery frame abuts against other components, the mutually abutting trapezoidal structures effectively restrain lateral movement at the abutment point when the battery box is impacted by a lateral force in the width direction. This further enhances the overall structure's resistance to lateral swaying in the abutment state, thereby strengthening the frame assembly 10's resistance to swaying and ultimately improving the overall stability of the battery box.

[0042] Among them, such as Figure 8 As shown, the plane 16 is set to be perpendicular to the bottom side unit 11 and parallel to the length direction of the first side plate.

[0043] Preferably, such as Figure 8 As shown, the first side unit 13 also includes a first groove 134 and a first protrusion 135. The first groove 134 is disposed on the first side plate 131. The first groove is disposed between the first upper inclined portion 132 and the second upper inclined portion 142. The first protrusion 135 is disposed on the first side plate 131. The first protrusion 135 is disposed between the first lower inclined portion 133 and the second lower inclined portion 143. The first groove 134 and the first protrusion 135 are correspondingly disposed. Figure 8 As shown, the second side unit 14 also includes a second groove 144 and a second protrusion 145. The second groove 144 is disposed on the second side plate 141. The second groove is disposed between the first upper inclined portion 132 and the second upper inclined portion 142. The second protrusion 145 is disposed on the second side plate 141. The second protrusion 145 is disposed between the first lower inclined portion 133 and the second lower inclined portion 143. The second groove 144 and the second protrusion 145 are correspondingly disposed. By the cooperation of the first groove 134 and the first protrusion 135, and the cooperation of the second groove 144 and the second protrusion 145, the connection tightness of adjacent components is further enhanced, and the stability of the connection between the battery frames is improved.

[0044] Furthermore, such as Figure 3 As shown, the first side unit 13 also includes a plurality of first connecting slots 136, providing a structural basis for battery frame connection. The first connecting slots 136 are recessed from the first side plate 131. The first connecting slots 136 are located on the side of the first side plate 131 away from the second side plate 141. The first connecting slots 136 are adjacent to the first downwardly inclined portion 133. The plurality of first connecting slots 136 provide clearance space for bolted connections between the first side plate 131 of the battery frame and other components, allowing bolted connections between the first side plate 131 of the battery frame and other components, increasing the stability of the connection between the battery frame and other components, and facilitating the assembly and maintenance of the frame assembly 10 and other components. Figure 2 As shown, the second side unit 14 also includes a plurality of second connecting slots 146. The second connecting slots 146 are recessed from the second side plate 141. The second connecting slots 146 are located on the side of the second side plate 141 away from the first side plate 131. The second connecting slots 146 are adjacent to the second downwardly inclined portion 143. The plurality of second connecting slots 146 provide clearance space for the second side plate 141 of the battery frame to be bolted to other components, allowing the second side plate 141 of the battery frame to be bolted to other components, further increasing the stability of the connection between the battery frame and other components, while also facilitating the assembly and maintenance of the frame assembly 10 and other components.

[0045] Preferably, the third side unit 15 further includes a plurality of third connecting slots 153. The third connecting slots 153 are recessed from the third side plate 151. The third connecting slots 153 are located on the side of the third side plate 151 away from the first side plate 131. The third connecting slots 153 are adjacent to the bottom side unit 11. The plurality of third connecting slots 153 provide clearance space for the third side plate 151 of the battery frame to be bolted to other components, thereby increasing the stability of the connection between the third side plate 151 of the battery frame and other components, and facilitating the assembly and maintenance of the frame assembly 10 and other components.

[0046] Furthermore, such as Figure 8 As shown, the third side unit 15 includes a third side plate 151 and a third recess 152. A first side plate 131, one third side plate 151, a second side plate 141, and another third side plate 151 are sequentially connected to form a ring. The side of the third side plate 151 away from the bottom side unit 11 is recessed towards the end closer to the bottom side unit 11 to form a third recess 152. By providing the third recess 152, clearance space is provided for the subsequent installation of the sealing assembly 40. At least a portion of the first recess 134, one of the third recesses 152, at least a portion of the second recess 144, and another third recess 152 are sequentially connected to form an annular groove.

[0047] Preferably, such as Figure 7 As shown, the battery frame also includes a sealing assembly 40. The sealing assembly 40 is disposed within the annular groove, which provides installation space for the sealing assembly 40. One side of the sealing assembly 40 abuts against the first groove portion 134, the second groove portion 144, or the third groove portion 152, ensuring a secure installation. The sealing assembly 40 forms a sealed structure between the two battery frames, preventing dust and other contaminants from entering the sealing assembly 40 and solving the problem of foreign matter (such as dust and rainwater) intrusion.

[0048] Furthermore, such as Figure 7 As shown, the bottom unit 11 includes a bottom plate 111 and a reinforcing plate 112. The bottom plate 111 is disposed on one annular side, forming a hollow cavity with an opening on one side. The reinforcing plate 112 is disposed within the hollow cavity. One side of the reinforcing plate 112 is fixedly connected to the bottom plate 111. One side of the reinforcing plate 112 is connected to one of the third side units 15, and the other side is connected to another third side unit 15. The reinforcing plate 112 reinforces the battery frame along its length. Since the battery box is too long and therefore lacks strength, the design of the reinforcing plate 112 increases the structural strength of the battery box, solving the problem of insufficient strength along the length of the battery frame. The set plane 16 is perpendicular to the bottom plate 111.

[0049] Example 2:

[0050] This embodiment discloses a battery module, which includes a battery frame as described in any of the above embodiments. For example... Figure 5 As shown, the battery module also includes an electrical connection assembly 20. The electrical connection assembly 20 is detachably connected to the bottom unit 11. Further, the electrical connection assembly 20 includes a connector 21, a connecting wire 22, and a battery pack 24. Figure 6 As shown, the battery pack 24 is housed within the hollow cavity of the battery frame. Connector 21 is detachably connected to a third-side unit 15. Connector 21 is electrically connected to the battery pack 24 via a connecting cable 22, the two ends of which are connected to the vehicle, enabling the battery pack 24 to power the vehicle.

[0051] Preferably, the bottom unit 11 includes a base plate 111 and a temperature control pipe (not shown in the figure). The base plate 111 is disposed on one annular side, forming a hollow cavity with an opening on one side. At least part of the temperature control pipe is disposed within the base plate 111, so that the temperature control agent in the temperature control pipe can exchange heat with the battery pack 24 through the base plate 111.

[0052] like Figure 5 As shown, the battery module also includes a temperature control component 30. The temperature control component 30 includes an inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 and the outlet pipe 32 are detachably connected to a third side unit 15. The inlet pipe 31, the temperature control pipe, and the outlet pipe 32 are sequentially connected to form a complete temperature control cycle. Furthermore, the temperature control component 30 also includes a temperature sensor, which is electrically connected to the temperature control component 30. The temperature sensor obtains the internal temperature of the battery module through the temperature control component 30, allowing the temperature control component 30 to control the heating or cooling of the battery module based on the internal temperature.

[0053] Example 3:

[0054] This embodiment discloses a battery box, such as Figure 4As shown, the battery box includes multiple battery modules as described in any of the above embodiments. These multiple battery modules are connected sequentially in a predetermined direction, and the combination of these modules enhances the power supply capacity of the battery box. In two adjacent battery modules, the first upward-sloping portion 132 of one battery module abuts against the first downward-sloping portion 133 of the other. Similarly, the second upward-sloping portion 142 of one battery module abuts against the second downward-sloping portion 143 of the other. Through the cooperation of the first upward-sloping portion 132 and the first downward-sloping portion 133, and the second upward-sloping portion 142 and the second downward-sloping portion 143, a portion of the lateral force is borne by the battery frame, thereby reducing the swaying of the battery box and ultimately solving the problem of insufficient stability caused by relative sliding of the battery frame. The electrical connection components 20 of the multiple battery modules are electrically connected, enabling multiple battery modules to collaboratively supply power to the vehicle, meeting the vehicle's power needs.

[0055] Preferably, such as Figure 2 As shown, the frame assembly 10 also includes a protective unit 12. The protective unit 12 includes a first cover plate 121. The first cover plate 121 is connected to the opening side on the outside of the battery module. The protective unit 12 seals the opening side on the outside through the first cover plate 121 to prevent dust from entering, thus solving the problem of dust intrusion.

[0056] Furthermore, the protective unit 12 also includes a second cover plate 122, which is disposed on the side of the third side unit 15 near the electrical connection assembly 20. The second cover plate 122 is spaced apart from the third side unit 15. One side of the second cover plate 122 is connected to the first side plate 131, and the other end is connected to the second side plate 141. By providing the second cover plate 122, foreign objects are prevented from entering the space where the electrical connection assembly 20 is located, and from being damaged by collisions or compression of the electrical connection assembly 20.

[0057] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
