Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle batteries, and in particular to an outer insulating protective sleeve for an on-board battery of a new energy vehicle. Background Art

[0002] The technology of new energy vehicles in all aspects has become increasingly mature, and batteries are the core components of new energy vehicles.

[0003] Batteries are typically fixed to the battery carrier inside new energy vehicles via connectors. The high speed of the vehicle can cause the battery to be subjected to significant impact and vibration. Severe vibration can cause the battery to collide with other components inside the vehicle, causing damage to the battery and other in-vehicle facilities. To address this issue, we have developed an outer insulating protective cover for onboard batteries in new energy vehicles. Summary of the Invention

[0004] The purpose of the present invention is to provide an outer insulating protective cover for a vehicle-mounted battery of a new energy vehicle, so as to solve the problems raised in the above-mentioned background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is an outer insulating protective cover for a vehicle-mounted battery of a new energy vehicle, comprising an insulating cover body, a fixing mechanism, and a cooling mechanism. The fixing mechanism and the cooling mechanism are both placed on the inner wall of the insulating cover body, and the fixing mechanism is placed above the cooling mechanism.

[0007] The fixing mechanism includes a cavity and a base plate, the inner wall of the cavity is provided with a through groove and an air inlet, the inner wall of the base plate is provided with a slide groove, the inner wall of the slide groove is slidably connected with a fixing component, the inner wall of the cavity is slidably connected with a main force transmission cone and a sub-force transmission cone, there are four sub-force transmission cones, a force transmission rod is fixedly installed at the bottom of the main force transmission cone, a pull-down shaft is fixedly installed on the outer wall of the fixing component, one end of the pull-down shaft is fixedly connected with a locking component, the locking component is arranged above the cavity, and a connecting plate is fixedly installed between the bottoms of every two force transmission sub-concretes.

[0008] The cooling mechanism includes an air outlet guide shaft, which is fixedly installed on the bottom of the base plate, an axial flow fan is fixedly installed on the bottom of the base plate, an air inlet pipe is fixedly installed on the bottom of the air outlet guide shaft, an opening and closing assembly is fixedly installed on the outer wall of the air inlet pipe, a cross air distribution plate is fixedly installed on the inner wall of the air outlet guide shaft, a lower pressure rod is fixedly installed on the bottom of the force transmission rod, a push plate is fixedly installed on the outer wall of the lower pressure rod, and a limit baffle is provided inside the air inlet pipe, and there are four limit baffles.

[0009] Furthermore, the fixed assembly includes an arm, both ends of the arm are movably connected with a push rod, the bottom of the arm is fixedly installed with a sliding shaft, one side of the arm is fixedly installed with a pressure block, the other side of the arm is fixedly installed with a return spring, the bottom of the connecting plate is fixedly installed with an extrusion rod, one end of the extrusion rod is fixedly installed on the outer wall of the force transmission rod, the other end of the extrusion rod is fitted with the outer wall of the pressure block, the outer wall of the fixing mechanism is fixedly installed with a limiting sliding shell, the outer wall of the arm is slidably connected to the inner wall of the limiting sliding shell, and one end of the push rod is slidably connected to the inner wall of the limiting sliding shell.

[0010] The above-mentioned technical solution is adopted. In this solution, the vehicle battery is placed in the cavity. The main force transmission cone and four auxiliary force transmission cones at the bottom of the cavity are moved downward by the pressure of the vehicle battery. The extrusion rod squeezes the pressure block to push the arm rod to move in the slide groove. When the vehicle battery completely enters the cavity, the arm rod moves from one end to the other end in the slide groove, and the push rod is driven by it to slide on the limiting inclined surface in the limiting sliding shell. Due to the setting of the limiting inclined surface, the push rod will be pressed by the limiting inclined surface and slide out of the through groove. The four groups of push rods cooperate with each other to firmly fix the vehicle battery in the cavity to prevent it from shaking and avoid the vehicle battery from running off due to vibration during driving, thereby fixing the battery on all sides.

[0011] Furthermore, the locking assembly includes a limit plate, the top of the limit plate is slidably connected to a slide rod, the top of the slide rod is fixedly installed with a locking plate, the outer wall of the locking plate is fixedly installed with a tensile spring, and one end of the pull-down shaft is fixedly installed with a push block.

[0012] The above technical solution is adopted, in which the arm is connected through a pull-down shaft. Therefore, when it is pressed down, the pull-down shaft pulls the push block downward, and the lock baffle is squeezed by the push block and slowly extends out, locking the battery in the cavity, thereby fixing the battery up and down.

[0013] Furthermore, the opening and closing assembly includes an air baffle, the outer wall of which is slidably connected to the inner wall of the air inlet pipe. There are four air baffles, and a pressure spring is fixedly installed on the outer wall of the air baffle. One end of the lower pressure rod is slidably connected to the inner wall of the air baffle.

[0014] The above-mentioned technical solution is adopted. In this solution, when the force transmission main stage is pressed down, the force transmission rod drives the lower pressure rod to squeeze downward. Four push plates are installed on the lower pressure rod. One end of the lower pressure rod is slidingly connected to the inner wall of the air baffle. When the lower pressure rod is pressed down, the push plate pushes the air baffle to squeeze the pressure spring to move outward. When the push plate touches the limit baffle, the air baffle is fully opened to play a blocking role.

[0015] Furthermore, an air supply pipe is fixedly installed on the bottom of the inner wall of the insulating sleeve, the outer wall of the air supply pipe is fixedly connected to the inner wall of the air inlet pipe, and filter inlet plates are fixedly installed on both ends of the air supply pipe.

[0016] With the above technical solution, when the car is driving, the wind flows along the air supply pipe into the air inlet pipe, and the incoming wind will enter the air outlet guide shaft, playing a role of leveraging.

[0017] Furthermore, an insulating cutter frame is provided inside the insulating sleeve, and the insulating cutter frame divides the inner wall of the insulating sleeve into six independent areas, and the structural features in each area are consistent.

[0018] The above technical solution is adopted, in which the insulating cutting frame divides the insulating sleeve into six independent areas. Although the structure in each area is the same, there is no direct connection between the areas. When one area is damaged, the other areas will not be affected, which plays a role in reducing losses.

[0019] Furthermore, an isolation plate is fixedly installed on the bottom of the inner wall of the insulating sleeve. There are four isolation plates. One end of the isolation plate is fixedly installed on the outer wall of the air outlet guide shaft. A closed cavity is formed between every two isolation plates.

[0020] The above technical solution is adopted, in which four isolation plates are provided on the periphery of the air outlet guide shaft, and a closed cavity is formed between every two isolation plates, which plays a role in concentrating the wind force.

[0021] The present invention has the following beneficial effects:

[0022] (1) When the present invention is used, the vehicle battery is placed in the cavity, and the main force transmission cone and the four auxiliary force transmission cones at the bottom of the cavity are moved downward by the pressure of the vehicle battery. The extrusion rod squeezes the pressure block to push the arm rod to squeeze the reset spring to move in the slide groove on the bottom plate. When the arm rod moves, it drives the push rod to move in the limit sliding shell. When the vehicle battery completely enters the cavity, the arm rod moves from one end in the slide groove to the other end, and the push rod is driven by it to slide on the limit inclined surface in the limit sliding shell. Due to the design of the limit inclined surface When the battery is fixed, the push rod will be pressed by the limiting inclined surface and slide out of the through groove. The four groups of push rods cooperate with each other to firmly fix the vehicle battery in the cavity to prevent the vehicle battery from shaking around. When it is pressed down, the pull-down shaft pulls the push block downward, and the lock baffle will be squeezed by the push block and slowly extend to lock the battery in the cavity to prevent the battery from shaking up and down in the cavity due to bumps. The fixing assembly and the locking assembly cooperate with each other to firmly fix the battery in the cavity to achieve a completely fixed effect.

[0023] (2) When the present invention is used, when the force-transmitting main cone is pressed down, the push plate pushes the air baffle to squeeze the pressure spring and move outward. When the push plate touches the limit baffle, the air baffle is fully opened. When the car is driving, the wind flows along the air supply duct into the air inlet duct, and the incoming wind will enter the air outlet guide shaft. Four isolation plates are arranged on the periphery of the air outlet guide shaft, and a closed cavity is formed between every two isolation plates. The wind in the air outlet guide shaft is divided into four parts by the cross air distribution plate, and flows along the air flow holes on the air outlet guide shaft into the closed cavity. The wind drives the axial flow fan at the bottom of the base plate to rotate, and the generated wind enters the cavity through the air inlet, cooling the vehicle battery, preventing the vehicle battery from burning due to excessive temperature, and achieving a cooling effect.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1-11 As shown, the present invention is an outer insulating protective cover for a vehicle-mounted battery of a new energy vehicle, comprising an insulating cover body 1, a fixing mechanism 3, and a cooling mechanism 7. The fixing mechanism 3 and the cooling mechanism 7 are both placed on the inner wall of the insulating cover body 1, and the fixing mechanism 3 is placed above the cooling mechanism 7.

The inner wall of the cavity 31 is slidably connected with a main force transmission cone 36 and a secondary force transmission cone 37. There are four secondary force transmission cones 37. A force transmission rod 361 is fixedly installed at the bottom of the main force transmission cone 36. A pull-down shaft 35 is fixedly installed on the outer wall of the fixing component 38.

A connecting plate 39 is fixedly installed between the bottoms of the sub-concave stages 37. The purpose of this arrangement is to achieve a fixing effect. When the vehicle battery is placed in the cavity 31, the force-transmitting main concave stage 36 and the four force-transmitting sub-concave stages 37 at the bottom of the cavity 31 move downward under the pressure of the vehicle battery.

Due to the setting of the limit inclined surface, The push rod 387 will be forced by the limiting inclined surface to slide out of the through groove 312. The four groups of push rods 387 will cooperate with each other to firmly fix the vehicle battery in the cavity 31 to prevent it from shaking around. Because the pull-down shaft 35 is connected to the arm rod 381, when it is pressed down, the pull-down shaft 35 pulls the push block 323 downward, and the lock plate 322 will be squeezed by the push block 323 and slowly extend out, locking the battery in the cavity 31 to prevent the battery from shaking up and down in the cavity 31 due to bumps. The fixing component 38 and the locking component 32 cooperate with each other to firmly fix the battery in the cavity 31.

A limited baffle 77 is provided inside the air inlet pipe 78, and there are four limited baffles 77. The purpose of this arrangement is to achieve the effect of cooling. When the force transmission main circular platform 36 is pressed down, the force transmission rod 361 drives the lower pressure rod 75 to squeeze downward, and four push plates 76 are mounted on the lower pressure rod 75. One end of the lower pressure rod 75 is slidably connected to the inner wall of the air baffle plate 741. When the lower pressure rod 75 is pressed down, the push plate 76 pushes the air baffle After the cam 741 is in the air, the air inlet 78 is pushed inwards and the air inlet 78 is pushed inwards, so that the air inlet 78 is pushed inwards and the air inlet 78 is pushed inwards.

[0043] The fixing assembly 38 includes an arm 381, both ends of the arm 381 are movably connected with a push rod 387, the bottom of the arm 381 is fixedly installed with a sliding shaft 386, one side of the arm 381 is fixedly installed with a pressure block 385, the other side of the arm 381 is fixedly installed with a return spring 384, the bottom of the connecting plate 39 is fixedly installed with an extrusion rod 382, one end of the extrusion rod 382 is fixedly installed on the outer wall of the force transmission rod 361, and the other end of the extrusion rod 382 is fitted with the outer wall of the pressure block 385.

The purpose of this arrangement is to To prevent the battery from shaking around, when the main force transmission stage 36 and the four force transmission auxiliary stages 37 are pressed and moved downward, the extrusion rod 382 squeezes the pressure block 385 and pushes the arm rod 381 to squeeze the return spring 384 to move in the slide groove 34 on the bottom plate 33. When the arm rod 381 moves, it drives the push rod 387 to move in the limiting sliding shell 383. When the vehicle battery completely enters the cavity 31, the arm rod 381 moves from one end in the slide groove 34 to the other end, and the push rod 387 is driven by it to slide on the limiting inclined surface in the limiting sliding shell 383. Due to the setting of the limiting inclined surface, the push rod 387 will be forced by the limiting inclined surface to slide out of the through groove 312. The four groups of push rods 387 cooperate with each other to firmly fix the vehicle battery in the cavity 31.

[0044] The locking block assembly 32 includes a limit plate 325, the top of the limit plate 325 is slidably connected to the slide bar 321, the top of the slide bar 321 is fixedly installed with a lock block 322, the outer wall of the lock block 322 is fixedly installed with a tension spring 324, and one end of the pull-down shaft 35 is fixedly installed with a push block 323. The purpose of this arrangement is to prevent the battery from shaking up and down. The pull-down shaft 35 is connected to the arm 381, so when it is pressed down, the pull-down shaft 35 pulls the push block 323 downward, and the lock block 322 will be squeezed by the push block 323 and slowly extend out, locking the battery in the cavity 31.

[0045] When the lock body 71 is unlocked, the lock body 71 is unlocked, and the lock body 71 is unlocked, so that the lock body 71 can be unlocked.

[0046] An air supply pipe 5 is fixedly installed at the bottom of the inner wall of the insulating sleeve 1, and the outer wall of the air supply pipe 5 is fixedly connected to the inner wall of the air inlet pipe 78. Filter inlet plates 4 are fixedly installed at both ends of the air supply pipe 5. The purpose of this arrangement is to facilitate air intake. When the car is driving, the wind flows along the air supply pipe 5 into the air inlet pipe 78, and the incoming wind will enter the air outlet guide shaft 72.

[0047] An insulating cutter 2 is provided inside the insulating sleeve 1, which divides the inner wall of the insulating sleeve 1 into six independent areas. The structural features in each area are consistent. The purpose of this setting is to accommodate multiple vehicle batteries. Although the structure in each area is the same, there is no direct connection between the areas. When one area is damaged, the other areas will not be affected.

[0048] An isolation plate 6 is fixedly installed at the bottom of the inner wall of the insulating sleeve 1. There are four isolation plates 6. One end of the isolation plate 6 is fixedly installed on the outer wall of the air outlet guide shaft 72. A closed cavity is formed between every two isolation plates 6.

[0049] When in use, the vehicle battery is placed in the cavity 31, and the main force transmission platform 36 and the four force transmission auxiliary platforms 37 at the bottom of the cavity 31 move downward under the pressure of the vehicle battery. Because four groups of through grooves 312 are provided on the inner wall of the cavity 31, the force transmission rod 361 at the bottom of the main force transmission platform 36 is connected to four extrusion rods 382, and the four force transmission auxiliary platforms 37 are connected to the four extrusion rods 382 through the connecting plate 39. The arm rod 381 is slidably connected to the bottom plate 33, and a push rod 387 is installed at each end of the arm rod 381. The bottom outer wall of the arm rod 381 is connected to a pressure block 385. Therefore, when the main force transmission platform 36 and the four force transmission auxiliary platforms 37 are pressed downward, the extrusion rod 382 squeezes the pressure block 385 to push the arm rod 381. The extrusion return spring 384 moves in the slide groove 34 on the bottom plate 33, and drives the push rod 387 to move in the limit sliding shell 383 while the arm rod 381 moves. When the vehicle battery completely enters the cavity 31, the arm rod 381 moves from one end in the slide groove 34 to the other end, and the push rod 387 is driven by it to slide on the limit inclined surface in the limit sliding shell 383. Due to the setting of the limit inclined surface, the push rod 387 will be pressed by the limit inclined surface and slide out from the through groove 312. The four groups of push rods 387 cooperate with each other to firmly fix the vehicle battery in the cavity 31 to prevent it from shaking around. Because the pull-down shaft 35 is connected to the arm rod 381, when it is pressed down, the pull-down shaft 35 pulls the push block 323 downward to squeeze When the locking plate 76 is in the closed position, the locking plate 722 is locked and the locking plate 723 is locked. At this time, the wind flows along the air supply pipe 5 into the air inlet pipe 78, and the entered wind will enter the air outlet guide shaft 72. A cross air distribution plate 71 is installed in the air outlet guide shaft 72, and four isolation plates 6 are arranged on the periphery of the air outlet guide shaft 72. A closed cavity is formed between every two isolation plates 6. Therefore, the wind in the air outlet guide shaft 72 will be divided into four parts by the cross air distribution plate 71, and enter the closed cavity along the air flow hole on the air outlet guide shaft 72. Then the wind drives the axial flow fan 73 at the bottom of the bottom plate 33 to rotate. The axial flow fan 73 generates wind upward while rotating. The wind generated by the wind passes through the air inlet 311 and enters the interior of the cavity 31 to cool down the vehicle battery, thereby preventing the vehicle battery from burning due to excessive temperature.
