[0001] The utility model belongs to the technical field of energy storage equipment transportation, and particularly relates to a battery rack and a battery cluster with the battery rack. Background Art

[0002] During the battery transfer process, manufacturers usually install several batteries in a battery rack and fix them with bolts, and then transport the whole to the installation site. However, they do not consider the continuous vibration suffered during transportation due to road conditions and other factors. Due to the heavy weight of the batteries, not only may the fastening bolts fall off or break under the influence of continuous vibration, but also the batteries may slide out of the battery rack. Content of the Utility Model

[0003] In view of this, the first object of the utility model is to provide a battery rack, which can solve the problem that the protection effect of the existing battery rack on the battery pack is limited.

[0004] The second object of the utility model is to provide a battery cluster with the battery rack.

[0005] To achieve the above technical object, the first aspect of the utility model provides a battery rack, which includes a main frame, a battery support beam and a gear linkage mechanism. The battery support beam is arranged in the main frame, and the gear linkage mechanism is arranged in the main frame and below the battery support beam. The battery support beam is provided with an avoidance hole. The gear linkage mechanism includes a mounting beam fixed in the main frame, a gear pair rotatably connected to the mounting beam, an elastic member hinged to the mounting beam, and a limiting plate connected between the elastic member and the gear pair. One end of the limiting plate penetrates through the avoidance hole and protrudes from the orifice of the avoidance hole under the restoring force of the elastic member.

[0006] In one embodiment, the limiting plate is provided with a limiting hole corresponding to the mounting beam, and the limiting plate is movably connected to the mounting beam through a pin penetrating through the limiting hole.

[0007] In one embodiment, the length direction of the limiting hole forms an acute angle with the horizontal plane.

[0010] In one embodiment, the horizontal plate is further provided with fixing holes corresponding to the batteries, and the batteries are fixedly connected to the horizontal plate through fixing members passing through the fixing holes.

[0011] In one embodiment, the vertical plate has a first limiting portion for limiting the battery in a first direction.

[0012] In one embodiment, the vertical plate further has a second limiting portion for limiting the battery in a second direction, and the second direction is perpendicular to the first direction.

[0013] In one embodiment, the main body frame includes a cross beam, a longitudinal beam and a column which are connected to each other, and a plurality of installation positions for accommodating batteries are formed between the cross beam, the longitudinal beam and the column.

[0014] The second aspect of the present utility model provides a battery cluster, including a battery and the battery rack as described in the above technical solution. A groove is provided at the bottom of the battery; when the battery is pushed into the battery rack along the length direction of the battery support beam under the action of an external force, one end of the limiting plate first swings downward to be flush with the orifice of the avoidance hole under the combined action of the gravity of the battery and the restoring force of the elastic member, and at the same time drives the gear pair to rotate. When the battery is pushed into a preset position, one end of the limiting plate swings upward under the action of the restoring force of the elastic member to protrude from the orifice of the avoidance hole or be stuck into the groove, and at the same time drives the gear pair to rotate in the reverse direction.

[0036] Please refer to Figure 1 and Figure 5 , an embodiment of the first aspect of the present utility model provides a battery rack 1 for installing a battery 2. It should be noted that the battery 2 mentioned here may refer to a battery pack in which a lithium-ion battery pack, a battery management system, and other necessary electrical components are packaged in a protective container. Its main function is to store electrical energy and deliver the electrical energy to an electric motor to drive a vehicle or supply power to other devices.

[0037] Specifically, the battery rack 1 includes a main body frame 11, a battery support beam 12, and a gear linkage mechanism 13. Among them, the battery support beam 12 and the gear linkage mechanism 13 are both installed in the main body frame 11. From the vertical direction, the battery support beam 12 is located above the gear linkage mechanism 13.

[0038] Overall, the main body frame 11 is in a frame structure, including cross beams 111, longitudinal beams 112, and columns 113 that are connected to each other. It should be noted that for the consideration of transporting as many batteries 2 as possible, a plurality of installation positions are formed between the cross beams 111, longitudinal beams 112, and columns 113, which is beneficial to reducing the transportation cost by accommodating a plurality of batteries 2.

[0039] Such as Figure 2As shown, the battery support beam 12 is used to support the battery 2. It is in the shape of a long strip plate and is installed between multiple columns 113 within the main frame 11, and the length direction is parallel to the length direction of the longitudinal beam 112. Specifically, the battery support beam 12 includes a horizontal plate 121 and a vertical plate 122 intersecting with the horizontal plate 121. Among them, the horizontal plate 121 is used to support the battery 2, and the vertical plate 122 is used to be fixedly connected to the column 113. It should be noted that after the battery 2 is installed in place, in order to stably fix the battery 2 on the horizontal plate 121, a fixing hole 125 corresponding to the battery 2 is opened at one end of the horizontal plate 121. The fixing hole 125 and the opening of the installation position are on the same side of the battery rack 1, which is convenient to fix the battery 2 on the horizontal plate 121 through the fixing member inserted into the fixing hole 125.

[0040] Furthermore, when the battery 2 is pushed into the battery rack 1 along the length direction of the battery support beam 12 under the action of an external force, in order to ensure that the battery 2 can be pushed to the preset position, a flanging 124 is formed at one end of the horizontal plate 121. The flanging 124 and the fixing hole 125 are respectively located at both ends of the horizontal plate 121, which is convenient to limit the battery 2 in the length direction of the battery support beam 12. In this embodiment, it is the left-right direction. Preferably, the shape of the flanging 124 is L-shaped.

[0041] Furthermore, a first limiting portion 126 and a second limiting portion 127 are formed on the outer surface of the vertical plate 122. Among them, both the first limiting portion 126 and the second limiting portion 127 are located on the same side of the vertical plate 122, and the second limiting portion 127 is located above the first limiting portion 126. Specifically, the first limiting portion 126 protrudes from the bottom side wall of the vertical plate 122 and is adjacent to the fixing hole 125, and is used to limit the battery 2 in the first direction. The first direction mentioned here can refer to the width direction of the vertical plate 122 or the length direction of the cross beam 111; the second limiting portion 127 protrudes from the top side wall of the vertical plate 122 and is used to limit the battery 2 in the second direction. The second direction mentioned here is perpendicular to the first direction and can refer to the height direction of the vertical plate 122 or the length direction of the column 113. In some embodiments, the number of both the first limiting portion 126 and the second limiting portion 127 can be multiple. In this embodiment, the number of the first limiting portion 126 on each vertical plate 122 is one, and the number of the second limiting portion 127 is two. When the battery 2 is installed in place in the battery rack 1 and is vibrated due to factors such as road conditions, under the action of the first limiting portion 126 and the second limiting portion 127, it is beneficial to reduce the vibration amplitude of the battery 2 in the battery rack 1.

[0042] As Figure 3 and Figure 4As shown in the figure, the gear linkage mechanism 13 includes a mounting beam 131, a gear pair 132, an elastic member 133, and a limiting plate 134. Among them, the mounting beam 131 is installed between multiple columns 113 within the main body frame 11 and is located below the battery support beam 12; the gear pair 132 is installed on the mounting beam 131 and is rotatably connected to the mounting beam 131; one end of the elastic member 133 is hinged to the mounting beam 131; the limiting plate 134 is connected between the elastic member 133 and the gear pair 132. Specifically, the elastic member 133 can refer to a spring and is pre-pressed between the mounting beam 131 and the limiting plate 134. The gear pair 132 includes two meshing gears. It should be noted that due to factors such as road conditions, the battery 2 is usually subjected to continuous vibration during transportation. In order to reduce the damage effect of vibration on the fixing parts and the battery 2, in this embodiment, an avoidance hole 123 is also provided on the horizontal plate 121 of the battery support beam 12. The avoidance hole 123 is located at the same end as the end of the horizontal plate 121 where the fixing hole 125 is provided, facilitating one end of the limiting plate 134 to pass through the avoidance hole 123 and being able to protrude from the orifice of the avoidance hole 123 under the action of the restoring force of the elastic member 133. Please refer to Figure 6 and Figure 7 . In this way, when the battery 2 is pushed into the battery rack 1 along the length direction of the battery support beam 12 under an external force, one end of the limiting plate 134 first swings downward to be flush with the orifice of the avoidance hole 123 under the combined action of the gravity of the battery 2 and the restoring force of the elastic member 133, and at the same time drives the gear pair 132 to rotate for the installation of the battery 2. When the battery 2 is pushed to the preset position, the above-mentioned end of the limiting plate 134 swings upward to protrude from the orifice of the avoidance hole 123 under the action of the restoring force of the elastic member 133, and at the same time drives the gear pair 132 to rotate in the reverse direction, which is beneficial to the secondary protection of the battery 2 in the battery rack 1 in the left and right directions, and is beneficial to further reducing the risk of the battery 2 slipping out of the battery rack 1 due to forced vibration and even being damaged.

[0043] In this embodiment, in order to ensure that the movement trajectory of the limiting plate 134 in the vertical direction is within the expected design requirements, a limiting hole 135 corresponding to the mounting beam 131 is provided in the middle of the limiting plate 134, facilitating the relative movable connection of the limiting plate 134 and the mounting beam 131 through a pin passing through the limiting hole 135. Specifically, the limiting hole 135 can be in the shape of a long hole or a long groove. Preferably, the length direction of the limiting hole 135 forms an acute angle with the horizontal plane, facilitating the limitation of the up and down swing range of the limiting plate 134 in the vertical direction.

[0044] Furthermore, in order to reduce the sliding friction between the battery 2 and the limiting plate 134 during the process of pushing the battery 2, a chamfer 136 is provided at one end of the limiting plate 134 passing through the avoidance hole 123. The chamfer can be in the shape of a wedge or an arc, facilitating the reduction of resistance.

[0045] An embodiment of the second aspect of the present utility model provides a battery cluster. Please refer to Figure 5 , which includes a battery 2 and a battery rack 1 as described in the above embodiment. Among them, the battery 2 is installed in the battery rack 1, and a groove (not shown in the figure) is provided at the bottom of the battery 2. In this way, when the battery 2 is pushed into the preset position, one end of the limiting plate 134 swings upward under the restoring force of the elastic member 133 to protrude from the orifice of the avoidance hole 123 or be inserted into the groove of the battery 2. In this embodiment, the left end of the left limiting plate 134 protrudes from the orifice of the avoidance hole 123, and the right end of the right limiting plate 134 is inserted into the groove of the battery 2. At the same time, the gear pair 132 is driven to rotate. In this embodiment, the left gear rotates clockwise and the right gear rotates counterclockwise. This not only makes the above battery cluster have high stability during transportation, but also can judge whether the battery 2 is properly installed in the battery rack 1 by observing whether the end of the left limiting plate 134 is flush with the orifice of the avoidance hole 123.

[0046] Compared with the prior art, the present utility model has the following beneficial effects:

[0047] By arranging a battery support beam for supporting the battery and a gear linkage mechanism for limiting the battery in the main body frame, and arranging a limiting structure capable of limiting the battery on the battery support beam, when the battery is pushed into the battery rack, the installation direction and installation position of the battery are not only ensured, but also beneficial to judging the installation condition of the battery in the battery rack, so as to overcome the damage effect of continuous vibration on the battery during the transportation of the battery.

[0048] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
