Description

Technical Field

[0001] This invention relates to the field of new energy battery trays, and discloses a modular combined liquid-cooled new energy battery tray with high heat dissipation. Background Technology

[0002] With the continuous development of new energy technologies, new energy vehicles have gradually become a core strategic development target for various countries and are a landmark product of technological and industrial transformation.

[0003] New energy batteries can be classified according to different material types as follows: lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-iron batteries, sodium-nickel chloride batteries, silver-zinc batteries, lithium batteries, air batteries (zinc-air batteries, aluminum-air batteries), solar batteries, sodium-sulfur batteries, etc.

[0004] Currently, ternary lithium batteries and lithium iron phosphate batteries are the dominant applications in passenger and commercial vehicles. To achieve effective heat dissipation, prevent battery overheating, and avoid dangerous accidents, cooling trays for new energy batteries are essential.

[0005] Existing new energy battery trays typically place a liquid cooling plate on the tray, and then place the battery on the liquid cooling plate to dissipate heat from the battery. However, when the battery tray is subjected to vibration or impact, the liquid cooling plate is prone to damage, leakage, or failure. Its poor stability is not conducive to long-term use, it is difficult to repair, and repair and replacement require a large amount of manpower and resources. Heat dissipation is usually concentrated in a local area, resulting in low heat dissipation efficiency. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention discloses a modular, combined liquid-cooled new energy battery tray with high-efficiency heat dissipation.

[0007] The technical solution of the present invention is: a modular combined liquid-cooled new energy battery tray with high-efficiency heat dissipation, including a support frame, and a tray combination unit, a cooling and heat dissipation unit, an early warning unit, and a shock absorption unit respectively disposed on the support frame and connected in sequence;

[0008] The tray assembly unit includes a base mounted on the support frame, multiple connectors that are movably snapped onto the base, an adjustment component that is correspondingly mounted on the connectors and used to clamp the new energy battery, a limiting plate movably mounted on the adjustment component, and a buffer component mounted on the limiting plate; the base is provided with mounting holes that can be correspondingly snapped onto the connectors.

[0009] The cooling and heat dissipation unit includes a cooling cavity disposed inside the base, multiple support frames disposed side by side inside the cooling cavity, a liquid cooling plate disposed on the inner side wall of the support frame, a heat dissipation fan disposed inside the support frame, and heat dissipation plates disposed one-to-one inside the support frame, with one end of the heat dissipation plate extending through to the outer wall of the base.

[0010] The base is provided with heat dissipation holes that can communicate with the cooling cavity; the longitudinal section of the support frame is inverted trapezoidal.

[0011] The early warning unit includes a pressure sensor disposed on the inner side wall of the support frame, a temperature sensor disposed on the base, a buzzer disposed on the base, and a microcontroller electrically connected to the pressure sensor, the temperature sensor, and the buzzer respectively.

[0012] The shock absorption unit includes multiple shock absorption columns arranged circumferentially on the outer wall of the base, and shock absorption springs and anti-collision blocks arranged one-to-one on the shock absorption columns. One end of the shock absorption spring is sleeved on the shock absorption column, and the other end of the shock absorption spring is fixedly connected to the anti-collision block.

[0013] Furthermore, the adjustment assembly includes a housing, a rotating shaft disposed on the housing, a first drive motor providing power to the rotating shaft, a first gear fixedly sleeved on the rotating shaft, a transmission gear set movably disposed on the housing and capable of meshing with the first gear, a second gear movably sleeved on the rotating shaft and capable of meshing with the transmission gear set, a first connecting rod set for connecting the first gear and the limiting plate, and a second connecting rod set for connecting the second gear and the limiting plate.

[0014] Explanation: The rotation of the shaft is controlled by the first drive motor, which drives the first gear fixedly mounted on the shaft to rotate, thereby controlling the movement of the first connecting rod assembly. The transmission gear set can drive the second gear to rotate in the opposite direction, effectively controlling the movement of the second connecting rod assembly. Because the first and second gears rotate in opposite directions, the first and second connecting rod assemblies can be controlled to translate in the same direction, which can efficiently adjust the position of the limit plate. Compared with conventional motor-controlled telescopic rod assemblies, this method can save space occupied by the drive device.

[0015] Furthermore, the first connecting rod assembly includes a first lever arm, a first transmission rod, and a first connecting rod. One end of the first lever arm is fixedly connected to the first gear, one end of the first transmission rod is movably hinged to the other end of the first lever arm, and one end of the first connecting rod is movably hinged to the other end of the first transmission rod.

[0016] Explanation: The rotation of the first gear can control the swing of the first lever arm, which in turn drives the first connecting rod to pull the limiting plate to move horizontally through the first transmission rod, effectively fixing the battery tray to the battery.

[0017] Furthermore, the second connecting rod assembly includes a second lever arm, a second transmission rod, and a second connecting rod. One end of the second lever arm is fixedly connected to the second gear, one end of the second transmission rod is movably hinged to the other end of the second lever arm, and one end of the second connecting rod is movably hinged to the other end of the second transmission rod.

[0018] Explanation: The rotation of the second gear can control the swing of the second lever arm, which in turn drives the second connecting rod to pull the limit plate to move horizontally via the second transmission rod, thereby improving stability and enhancing the battery tray's ability to fix and control the battery.

[0019] Furthermore, the housing is provided with through holes through which the first connecting rod and the second connecting rod can pass.

[0020] Note: The housing protects the internal components of the adjustment assembly. The first and second connecting rods pass through the through holes to control the push and pull of the limiting plate.

[0021] Furthermore, the buffer assembly includes a first spring sleeved on the first connecting rod and located between the housing and the limiting plate, a second spring sleeved on the second connecting rod and located between the housing and the limiting plate, and a plurality of buffer pads spaced apart on the limiting plate.

[0022] Explanation: The first spring and the second spring, respectively fitted on the first connecting rod and the second connecting rod, can limit the position of the limiting plate to prevent it from colliding and being damaged by the shell; the use of buffer pads can reduce the squeezing and collision between the limiting plate and the battery, thus improving safety.

[0023] Furthermore, the shock-absorbing column is provided with a mounting groove for installing a shock-absorbing spring; the shock-absorbing column is made of neoprene rubber.

[0024] Note: The shock-absorbing columns and springs can reduce the damage to the battery caused by impacts from the battery tray; the neoprene rubber material is wear-resistant, shockproof, and stable, enhancing its practicality.

[0025] Furthermore, the anti-collision block is made of polyethylene foam board; a waterproof board is provided on the support frame above the base.

[0026] Note: The anti-collision blocks made of polyethylene foam board are installed on the shock-absorbing columns, which can not only enhance the anti-collision and shock absorption effect, but also avoid affecting the heat dissipation of the battery tray; the waterproof board can make the battery tray waterproof and prevent water from entering and damaging the circuit.

[0027] Furthermore, the base is provided with hooks for installing flame-retardant covers; the bottom of the base is provided with anti-slip strips; the anti-slip strips are made of rubber.

[0028] Note: The flame-retardant cover is installed via hooks on the base to further enhance the safety of the device; the anti-slip strips increase the friction of the base and improve the stability of the device.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) The device of the present invention fixes the battery to the tray base through the tray assembly unit, and installs the adjustment component through the mounting hole corresponding to the plug-in to realize the combined control of the internal space of the battery tray, which is convenient for adjustment and maintenance; the adjustment component controls the movement of the limit plate, which solves the problem of unstable battery placement caused by the mismatch between the battery tray and the battery size; when the battery tray is subjected to vibration or collision, the buffer component can reduce the impact on the battery and improve safety.

[0031] (2) The device of the present invention utilizes a support frame set inside the cooling chamber to fix the liquid cooling plate, effectively enhancing stability and solving the problem of easy damage and leakage of the liquid cooling plate on conventional battery trays, and is easy to adjust and maintain; the heat dissipation fan set inside the support frame effectively enhances the cooling efficiency and achieves uniform heat dissipation; the heat dissipation effect is improved by the heat dissipation plate that penetrates to the outer wall of the base.
