Description

Technical Field

[0001] The utility model relates to the field of automobile underbody guard plates, in particular to an automobile underbody guard plate assembly. Background Art

[0002] When a car is driving, the tires will roll up the sand and gravel when they crush it, causing the sand and gravel to collide with the engine and other structures, causing engine damage; and when there is mud and water on the road, mud and water will form and be rolled up by the tires. The rolled up mud, water, sand and gravel can easily wrap around the engine and even enter the gaps in the engine, gearbox, etc., causing damage to the engine, gearbox, etc. and the car to break down. Therefore, a bottom guard plate is usually provided at the bottom of the car.

[0003] The traditional bottom guard is a whole plate-like structure, but with the increasing number of new energy vehicles, the batteries of new energy vehicles are mostly placed under the vehicle, and the strength of the current plastic bottom guard is difficult to provide adequate protection for the battery. Later, although the patent "A battery bottom guard" with application number CN202221671939.7 appeared, the main part of the bottom guard is set as a honeycomb structure, and a second part is set, the second part is composed of a first layer and a second layer, the first layer and the second layer are respectively attached to the upper and lower surfaces of the first part, and the second part is used to strengthen the structural strength of the first part.

[0004] Although the above-mentioned bottom guard plate increases the strength and protects the battery, the battery will generate heat when working at high intensity. The above-mentioned bottom guard plate will also cause poor heat dissipation of the battery, thereby causing high temperature of the battery. Utility Model Content

[0005] The utility model aims to provide an automobile underbody guard assembly to solve the problem of high temperature caused by poor heat dissipation of batteries after the underbody guard is installed.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automobile underbody guard assembly, including an underbody guard body, an air guide inner groove is arranged in the underbody guard body, an air inlet and an air outlet are arranged on the side wall of the underbody guard body, both of which are connected with the air guide inner groove, and the air inlet and the air outlet are respectively located on two opposite side walls of the underbody guard body; a heat dissipation air outlet connected with the air guide inner groove is arranged on the top of the underbody guard body, an inclined guide plate is arranged on the top of the air guide inner groove, the inclined guide plate is opposite to the heat dissipation air outlet, and the end of the inclined guide plate close to the air inlet is fixed to the top of the air guide inner groove, and the end close to the air outlet is inclined downward.

[0007] The beneficial effects of this program are:

[0008] 1. When the car is running, the outside air can form airflow in the air guide groove through the air guide groove, and the heat generated by the battery can be transferred to the air in the air guide groove and quickly discharged with the airflow, thereby effectively improving the heat dissipation effect of the battery. After the bottom guard plate is installed, it can shield the battery to prevent stones and other objects from colliding with the battery, so it can also maintain a good protection effect on the battery.

[0009] 2. The design of the heat dissipation vents enables the heat generated by the battery to be transferred to the air in the air guide inner slot more quickly, thereby further improving the heat dissipation effect of the battery and avoiding high temperature damage to the battery.

[0010] 3. The inclined guide plate in this solution is located below the heat dissipation vents, which can shield the heat dissipation vents. Even if stones, dust and other objects from the outside enter the air guide inner groove, they will not directly collide with the battery from the heat dissipation vents due to the shielding effect of the inclined guide plate, thereby further improving the protection effect on the battery.

[0011] Furthermore, a plurality of heat dissipation vents and inclined guide plates are provided, and the inclined guide plates correspond to the heat dissipation vents one by one.

[0012] The beneficial effect of this solution is that more heat dissipation vents can further improve the heat dissipation effect of the battery.

[0013] Furthermore, a protective groove with an upward opening is provided on the top of the bottom guard plate body, and the heat dissipation vent connects the protective groove with the air guide inner groove.

[0014] The beneficial effect of this solution is that when the bottom guard plate body is installed, the protective groove can accommodate the battery, so that the bottom guard plate body can cover the battery to protect the side wall of the battery.

[0015] Furthermore, a side hole plate is fixed to the side wall of the bottom guard plate body, and the vertical projection of one end of the side hole plate away from the protection body is located outside the bottom guard plate body.

[0016] The beneficial effect of this solution is that the bottom guard plate assembly of this solution can be installed more conveniently through the side hole plate.

[0017] Furthermore, the side wall of the bottom guard plate body is provided with a maintenance slot and is detachably connected with a sealing side plate, the maintenance slot is communicated with the air guide inner slot, and the sealing side plate is used to seal the maintenance slot.

[0018] The beneficial effect of this solution is that opening the maintenance slot can more conveniently clean the inside of the air guide inner slot, thereby preventing dust from accumulating in the air guide inner slot.

[0019] Furthermore, two dust baffles are hinged on the side wall of the protective plate, and the two dust baffles are respectively opposite to the air inlet and the air outlet and can respectively close the air inlet and the air outlet.

[0020] The beneficial effect of this solution is that when the car is not driving, the dust baffle can close the air inlet and the air outlet to prevent external dust from entering the air guide inner groove through the air inlet and the air outlet.

[0021] Furthermore, a limit block is fixed on the side wall of the air guide inner groove, and the limit block is opposite to the air inlet.

[0022] The beneficial effect of this solution is that the limit block can limit the rotation angle of the dust baffle so that the rotation angle of the dust baffle is less than 90°, thereby preventing the dust baffle from rotating too much and causing the air inlet to open too wide, causing external stones to enter the air guide inner groove and be difficult to clean.

[0023] Furthermore, a connecting rod is hinged between the two dustproof baffles, and the connecting rod and the two dustproof baffles form a parallelogram mechanism.

[0024] The beneficial effect of this solution is that when the dust baffle at the air inlet is pushed by the airflow, under the action of the connecting rod, the dust baffle at the air outlet will also open, reducing the obstruction of the airflow passing through the air guide inner groove, improving the heat dissipation effect, and facilitating the airflow to blow out the dust and other objects in the air guide inner groove.

[0029] The following is further described in detail through specific implementation methods:

[0030] The figure marks in the drawings of the specification include: bottom guard plate body 1, protective groove 2, air guide inner groove 3, side hole plate 4, heat dissipation vent 5, dust baffle 6, inclined guide plate 8, connecting rod 9, maintenance slot 10, sealing side plate 11, and limit block 12.

[0031] Example 1

[0032] Example 1 is basically as Figure 1 , Figure 2 and Figure 3As shown, it includes a bottom guard plate body 1 and two side hole plates 4. The bottom guard plate body 1 and the side hole plates 4 in this embodiment are both made of aluminum alloy. The two side hole plates 4 are respectively located on the front and rear sides of the bottom guard plate body 1 and are welded to the bottom guard plate body 1. A protective groove 2 with an opening facing upward is provided on the top of the bottom guard plate body 1, which is used to accommodate batteries during installation to protect the batteries.

[0033] The bottom guard plate body 1 is provided with an inner air guide groove 3, which in this embodiment is located below the protective groove 2. A plurality of heat dissipation vents 5 are provided at the bottom of the protective groove 2, and a plurality of inclined guide plates 8 are welded to the top of the inner air guide groove 3. The number of the inclined guide plates 8 in this embodiment is the same as the number of the heat dissipation vents 5. Specifically, the inclined guide plates 8 correspond to the heat dissipation vents 5 one by one, and the left end of the inclined guide plate 8 is welded to the top side wall of the inner air guide groove 3, and the right end is tilted downward.

[0034] The left wall of the bottom guard body 1 is provided with an air inlet, and the right wall is provided with an air outlet, and both the air inlet and the air outlet are connected to the air guide inner groove 3. Dust baffles 6 are provided at the air inlet and the air outlet, and the dust baffles 6 are hinged to the bottom guard body 1, so that the dust baffle 6 on the left side closes the air inlet, and the dust baffle 6 on the right side closes the air outlet.

[0035] Two connecting rods 9 are also provided in the air guide inner groove 3. The left ends of the two connecting rods 9 are respectively opposite to the dust baffle 6 on the left side, and are hinged to the lower end of the dust baffle 6 through a pin, and the right ends are respectively hinged to the dust baffle 6 on the right side, and the hinged positions are the lower ends of the two dust baffles 6. The connecting rod 9 and the two dust baffles 6 in this embodiment form a parallelogram mechanism, so that when the connecting rod 9 on the left side swings counterclockwise, the dust baffle 6 on the right side is driven to swing counterclockwise through the connecting rod 9.

[0036] The front side wall of the bottom guard plate body 1 is provided with a sealing side plate 11 and a maintenance slot 10 communicating with the air guide inner slot 3 . The sealing side plate 11 is connected to the bottom guard plate body 1 by bolts and is used to close the maintenance slot 10 .

[0037] The specific implementation process is as follows:

[0038] During installation, the battery is located in the protective groove 2, and the side hole plate 4 is attached to the bottom of the car. Bolts are used to install the side hole plate 4 on the bottom of the car. When in use, the side wall of the protective groove 2 can protect the battery. When the car is driving to the left, the dust baffle 6 on the left side swings counterclockwise under the action of the airflow, and the dust baffle 6 on the right side swings counterclockwise through the connecting rod 9, so that the airflow flows from left to right relative to the bottom guard plate body 1: the airflow enters the air guide inner groove 3 from the air inlet and is discharged from the air outlet. In this process, the heat generated by the battery is transferred to the air in the air guide inner groove 3 through the side wall of the bottom guard plate body 1 and the heat dissipation vents 5, and is discharged from the air outlet together with the airflow, while maintaining a good protection for the battery, the heat dissipation effect is improved to avoid high temperature damage to the battery.

[0039] When the car is not started, the two dust shields 6 respectively close the air inlet and the air outlet under the action of gravity to prevent stones and dust from entering the air guide inner groove 3. During the driving process of the car, even if there is a possibility that stones and other objects from the outside may enter the air guide inner groove 3 because the air inlet is open, they can be discharged from the air outlet along with the air flow, and the inclined bevel guide plate 8 can guide the air flow and shield the heat dissipation air outlet 5 to prevent stones from colliding with the battery from the heat dissipation air outlet 5, so the battery can still be protected.

[0040] When dust accumulates in the air guide inner groove 3 , the sealing side plate 11 is opened and the dust can be cleaned through the maintenance slot 10 .

[0041] Example 2

[0042] On the basis of Example 1, Figure 4 As shown, in this embodiment, a limit block 12 is provided on the right side of the left dust baffle 6. The limit block 12 in this embodiment is welded to the bottom side wall of the air guide inner groove 3, so that the dust baffle 6 is blocked by the limit block 12 after rotating counterclockwise at a certain angle, and cannot rotate 90°. The blocking of the limit block 12 can further limit the opening angle of the air inlet, and prevent the air inlet from being opened too wide, resulting in stones with too large particle sizes from entering the air guide inner groove 3, which is difficult to clean, and causing damage to the side wall of the air guide inner groove 3 and the connecting rod 9 and other structures.

[0043] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
