[0033] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0034] The following is for reference. Figures 1-5 The battery box 100 according to an embodiment of the present utility model is described.

[0035] Reference Figure 1 and Figure 2 As shown, the battery box 100 of the first aspect of the present invention includes: a shell 10, a partition 20 and a limiting pressure plate 30. The outer wall of the shell 10 is provided with an insertion hole 11. The partition 20 is disposed on the inner wall of the shell 10, thereby dividing the space inside the shell 10 into at least two battery placement spaces, which are respectively used to place batteries. The limiting pressure plate 30 passes through the insertion hole 11 and abuts against the bottom of the partition 20.

[0036] Specifically, the battery box 100 is mainly composed of a shell 10, a partition 20 and a limiting pressure plate 30. The outer wall of the shell 10 is provided with an insertion hole 11, which can facilitate the insertion of the limiting pressure plate 30. The number of limiting pressure plates 30 can also be selected according to the arrangement of the batteries in the battery box 100.

[0037] Furthermore, the partition 20 is disposed on the inner wall of the housing 10, so that the partition 20 can divide the space inside the housing 10 into at least two layers of battery placement space, which can not only increase the number of batteries that can be placed, but also separate the batteries in adjacent layers, thereby avoiding the concentration of heat generated by the batteries.

[0038] Furthermore, the limiting pressure plate 30 passes through the insertion hole 11 and abuts against the bottom of the partition 20. In this way, the limiting pressure plate 30 and the partition 20 work together to increase the distance between adjacent battery layers in the height direction of the housing 10, that is, to increase the gap between adjacent battery layers, thereby facilitating air flow, reducing heat accumulation, and having a better heat dissipation effect.

[0039] Therefore, the limiting pressure plate 30 in the battery box 100 has a through hole 11 that abuts against the bottom of the partition 20, which can increase the gap between adjacent layers of batteries in the height direction of the housing 10, thereby facilitating air flow, reducing heat accumulation, and having a better heat dissipation effect.

[0040] According to some embodiments of this utility model, such as Figure 2 As shown, the partition 20 is provided with multiple storage slots 21 for placing batteries, and a portion of the limiting pressure plate 30 is located at the bottom of the storage slot 21.

[0041] The partition 20 is hollowed out to form multiple storage slots 21, which can place multiple batteries independently. The independent storage slots 21 can improve air circulation, make the temperature around each battery more uniform, avoid local overheating, and thus extend the overall life of the battery.

[0042] In addition, each battery has an independent storage slot 21, which reduces the possibility of direct contact between batteries, thereby reducing the risk of short circuits caused by accidental contact.

[0043] Furthermore, a portion of the limiting pressure plate 30 is located at the bottom of the storage slot 21, so that the limiting pressure plate 30 can support and fix the battery, thereby preventing the battery in the storage slot 21 from shifting.

[0044] According to some embodiments of this utility model, such as Figure 2 As shown, the inner wall of the housing 10 is provided with a groove 12 extending along the height direction of the housing 10, and the spacer 20 is slidably disposed in the groove 12.

[0045] The spacer 20 can slide along the groove 12 on the inner wall of the housing 10, which not only serves to position and install the spacer 20, but also has the advantage of saving effort when the spacer 20 slides in the groove 12.

[0046] According to a specific embodiment of the present invention, the limiting pressure plate 30 includes a fixing part 31 and a limiting part 32. The fixing part 31 can be fixed to the outer periphery of the insertion hole 11, and the limiting part 32 is connected to the fixing part 31. Moreover, the limiting part 32 is disposed inside the housing 10, and the top surface of the limiting part 32 is in contact with the bottom of the partition 20.

[0047] Specifically, when the limiting part 32 is fully inserted into the housing 10, the fixing part 31 engages with the outer periphery of the insertion hole 11 to limit the movement of the limiting pressure plate 30 away from the housing 10.

[0048] Furthermore, fixing holes 311 can be provided on both sides of the fixing part 31, and screws can be passed through the fixing holes 311 to further fix the limiting pressure plate 30 to the housing 10.

[0049] Furthermore, the top surface of the limiting part 32 is in contact with the bottom of the partition 20, so that the limiting part 32 can serve as the bottom of the storage slot 21 in the partition 20 and can also provide some support for the partition 20.

[0050] According to some embodiments of this utility model, such as Figure 3 As shown, the limiting pressure plate 30 also includes an elastic part 33 and a sliding piece 34. The elastic part 33 is located at the bottom of the limiting part 32 and is stacked with the limiting part 32. The sliding piece 34 is stacked at the bottom of the elastic part 33 and is used to press the top of the battery.

[0051] The elastic part 33 is located at the bottom of the limiting part 32. The elastic part 33 can be set as a rubber pad. Since the limiting pressure plate 30 is located between two adjacent battery layers, the rubber pad can undergo elastic deformation under force, which can make the fit between the two adjacent battery layers and the limiting pressure plate 30 tighter and also play a buffering role.

[0052] Furthermore, the sliding plate 34 is stacked at the bottom of the elastic part 33. For example, a battery is provided on the partition 20, and a battery is also provided in the housing 10 below the partition 20. The sliding plate 34 is pressed and engaged with the battery below the partition 20, which not only increases the distance between the battery on the partition 20 and the battery below the partition 20 in the height direction of the housing 10, increasing airflow, but also prevents the battery from moving. The battery below the partition 20 also provides a certain support for the limiting pressure plate 30.

[0053] According to some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the battery box 100 also includes a heat dissipation window 40, and a heat dissipation vent 41 is provided on the outer wall of the housing 10. The heat dissipation window 40 is movably disposed on the heat dissipation vent 41.

[0054] When the internal temperature of the casing 10 is too high, the gas pressure increases due to the heat, and the gas can be discharged outward through the heat dissipation window 40, thereby achieving a better exhaust and heat dissipation effect.

[0055] Furthermore, the heat dissipation window 40 can be movably disposed at the heat dissipation vent 41. When the internal temperature of the housing 10 rises further, the heat dissipation window 40 can be moved to open the heat dissipation vent 41, thereby further accelerating the airflow and improving the heat dissipation effect.

[0056] According to some embodiments of the present invention, the heat dissipation window 40 includes: a driving member, a pull wire, and a mesh member 42. One end of the pull wire is connected to the driving member. The mesh member 42 includes a mesh frame 421 and a mesh 422. The mesh 422 is disposed on the mesh frame 421. The mesh frame 421 is connected to the other end of the pull wire. The driving member drives the mesh frame 421 to be movably disposed on the heat dissipation opening 41 through the pull wire, thereby opening and closing the heat dissipation opening 41.

[0057] The driving component can be a motor. One end of the pull wire is connected to the output end of the motor, and the other end of the pull wire is connected to the mesh frame 421. When the motor is started, the motor moves the mesh frame 421 by pulling the pull wire. The motor can open and close the heat dissipation vent 41 of the mesh frame 421 by rotating forward and backward.

[0058] Furthermore, since the mesh 422 is located in the mesh frame 421, when the temperature inside the housing 10 is not high, there is no need to open the heat dissipation vent 41. The mesh 422 can also allow air to circulate, thus playing a role in heat dissipation.

[0059] According to some embodiments of this utility model, such as Figure 1 As shown, a lock hole is provided on the outer wall of the mesh frame 421, and an electric lock 43 is provided on the outer wall of the housing 10. The electric lock 43 can selectively cooperate with the lock hole for unlocking and locking the mesh component 42.

[0060] The electric lock 43 includes a mechanical switch and a control circuit board (chip). The control system of the control circuit board can control the mechanical switch to engage with the lock hole on the outer wall of the mesh frame 421, thereby locking the mesh component 42.

[0061] Furthermore, the electric lock 43 can selectively engage with the keyhole limit switch. That is, the mechanical switch of the electric lock 43 can be controlled to engage with the keyhole limit switch, or it can be controlled to disengage from the keyhole, thus enabling it to be used for unlocking and locking the mesh component 42. The electric lock 43 can also be operated remotely.

[0062] According to some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the battery box 100 also includes a base 50 and a cover 60. The base 50 has a mounting groove 51. The housing 10 is placed in the mounting groove 51. A damper 52 and an elastic member 53 are provided at the bottom of the mounting groove 51. The elastic member 53 is sleeved on the outer periphery of the damper 52. An opening 13 is formed at the top of the housing 10. The cover 60 covers the opening 13.

[0063] The mounting slot 51 can provide a mounting position for the housing 10 and also prevent the housing 10 from moving.

[0064] Furthermore, a positioning hole 54 is provided at the bottom of the mounting groove 51, and a damper 52 is provided at the positioning hole 54. An elastic element 53 is sleeved on the outer periphery of the damper 52. The elastic element 53 can be set as a spring. In this way, the damper 52 and the spring can work together to reduce vibration, thereby achieving a better vibration reduction and buffering effect on the battery box 100 and the internal battery of the housing 10.

[0065] Furthermore, the top of the casing 10 has an opening 13, which facilitates the insertion and removal of the battery. The cover 60 seals the opening 13, thus protecting the battery inside the casing 10.

[0066] Furthermore, the cover 60 is provided with mounting holes 61, through which bolts can pass to make the connection between the cover 60 and the housing 10 more stable and secure.

[0067] The vehicle according to a second aspect of the present invention includes: the battery box 100 of the above embodiment.
