Description

Technical Field

[0001] The invention relates to a heat dissipation grille, in particular to a rotary heat dissipation grille for a battery compartment of a bus; and also to an automatic rainproof wind-increasing heat dissipation control method having the rotary heat dissipation grille for the battery compartment of a bus. Background Art

[0002] At present, environmental problems and energy crises are becoming increasingly severe. These two major problems have brought huge challenges to the development of the automotive industry in countries around the world. As one of the most promising products among new energy vehicles today, electric buses have gradually replaced fuel buses and become a major component of urban public transportation. As the main power source for electric buses, the performance of batteries directly determines the power performance of the entire vehicle. However, during the driving of the bus, the battery in the working state will generate a lot of heat. If the heat cannot be dissipated in time, the battery life will be greatly reduced and the charging and discharging performance will also be affected. When the operating temperature of the battery accumulates to a certain height, a high temperature alarm will be generated and the work will stop, which will cause the bus to lose its power source and be forced to stop, causing serious traffic accidents.

[0003] At present, electric buses mainly use air cooling to dissipate heat from the battery compartment, thereby reducing the working environment temperature of the battery. Installing a grille on the battery compartment door can introduce outside air into the compartment, and take the heat discharged from the battery box out of the battery compartment, achieving the effect of air cooling. Currently, the most common forms of heat dissipation grilles are horizontal grilles and vertical grilles. Although the vertical grille with a windward opening can effectively increase the air intake, it will also greatly increase the chance of rainwater entering the compartment; while the horizontal grille can enhance the waterproof effect, but the air intake will be reduced. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems of the prior art and to provide a rotating bus battery compartment cooling grille which has good rainproof effect and is convenient for increasing the air intake to achieve air cooling and heat dissipation of the battery compartment. An automatic rainproof and wind-increasing heat dissipation control method having the rotating bus battery compartment cooling grille is also provided.

[0005] In order to achieve the above object, the present invention adopts the central scheme:

[0006] The rotating bus battery compartment heat dissipation grille comprises a battery compartment door; the battery compartment has a heat dissipation opening; the rotating bus battery compartment heat dissipation grille also comprises:

[0007] A grille panel, which is cooperatively disposed in the heat dissipation vent and communicates with the heat dissipation vent, and can rotate 360 ​​degrees horizontally relative to the battery compartment door;

[0009] Furthermore, the grille panel comprises:

[0010] A panel body, which is cooperatively disposed in the heat dissipation opening and connected to the rotation drive device;

[0011] A plurality of grille openings arranged and distributed on the panel body and connected to the heat dissipation opening;

[0012] A plurality of grille blocking pieces are respectively connected to the panel body and are obliquely arranged above each grille opening corresponding to each grille opening.

[0013] Furthermore, the angle formed between the grille baffle and the corresponding grille opening is 20 ° ~70 ° .

[0014] Furthermore, the grille baffle is an arc-shaped grille baffle.

[0015] Furthermore, the grille opening is a rectangular strip grille opening.

[0016] Furthermore, a plurality of the grille openings and the corresponding grille blocking pieces are arranged in a square shape on the panel body.

[0017] Furthermore, the rotation driving device is a micro motor; the output shaft of the micro motor is connected to the grille panel.

[0018] Furthermore, the rotation drive device is connected to the battery compartment door via a support rod.

[0019] Furthermore, the support rod includes a first bending portion, a connecting rod and a second bending portion; one end of the first bending portion is connected to the battery compartment door; the other end is connected to one end of the connecting rod; the other end of the connecting rod is connected to the second bending portion; the second bending portion is located at the center of the heat dissipation outlet and is connected to the rotation drive device.

DETAILED DESCRIPTION

[0037] The present application is further described in conjunction with the following examples.

[0038] like Figures 1 to 8 The rotating bus battery compartment heat dissipation grille is mainly used in electric buses, and includes a battery compartment door 1; the battery compartment has a heat dissipation vent 2; the rotating bus battery compartment heat dissipation grille also includes a grille panel 3 and a rotation drive device 4. The grille panel 3 is matched and arranged in the heat dissipation vent 2 and communicated with the heat dissipation vent 2, and can rotate 360 ​​degrees horizontally relative to the battery compartment door 1; the rotation drive device 4 is located at the center of the grille panel 3 and connected to the grille panel 3, and drives the grille panel 3 to rotate 360 ​​degrees horizontally relative to the battery compartment door 1.

[0039] The rotating bus battery compartment heat dissipation grille is provided with a grille panel 3 at the heat dissipation opening 2, the rotating drive device 4 is connected to the grille panel 3, and the grille panel 3 is driven to rotate 360 ​​degrees horizontally relative to the battery compartment door 1, so as to realize the rotation adjustment of the grille panel 3 relative to the battery compartment door 1. According to different weather conditions, the grille panel 3 can be driven to rotate by controlling the rotating drive device 4 to change the opening direction of the grille panel 3, thereby controlling the air intake in the battery compartment, improving the heat dissipation effect, and achieving a waterproof effect. According to different weather conditions, the rotating drive device 4 can be controlled to drive the grille panel 3 to rotate and change the opening direction of the grille panel 3: on sunny days, the grille panel 3 is driven to rotate to a vertical and windward form to increase the air intake in the battery compartment; on rainy days, the grille panel 3 is driven to rotate to a horizontal form to appropriately reduce the entry of rainwater into the battery compartment; in heavy rain, the grille panel 3 is driven to rotate to a vertical and leeward form to prevent rainwater from entering the battery compartment. Compared with the existing technology, the rotating bus battery compartment heat dissipation grille has a good automatic rainproof effect, which can prevent rainwater from entering the battery compartment, and can reasonably increase the air intake to achieve air cooling and heat dissipation in the battery compartment.

[0040] Preferably, the rotation drive device 4 is a micro motor, and the output shaft of the micro motor is connected to the grille panel 3. The grille panel 3 is driven to rotate by the micro motor, and the opening direction of the grille panel 3 is changed, thereby controlling the air intake in the battery compartment, improving the heat dissipation effect, and achieving a waterproof effect.

[0041] Specifically, the grille panel 3 includes a panel body 31, a grille opening 32 and a grille baffle 33. The panel body 31 is arranged in the heat dissipation passage 2 and connected to the rotation drive device 4; a plurality of grille openings 32 are arranged and distributed on the panel body 31 and communicate with the heat dissipation passage 2; a plurality of grille baffles 33 are respectively connected to the panel body 31 and are obliquely arranged above the grille opening 32 corresponding to each of the grille openings 32. By providing a plurality of grille openings 32 on the panel body 31, it is convenient to increase the air intake in the battery compartment to achieve air cooling and heat dissipation. The grille baffle 33 is obliquely arranged on each grille opening 32 to block the grille opening 32, which can prevent rainwater from entering the battery compartment on the one hand and does not affect the wind from entering the battery compartment on the other hand. Under different weather conditions, the rotation drive device 4 can change the opening direction of the grille panel 3 by driving the grille panel 3 to rotate, which can prevent rainwater from entering the battery compartment and can reasonably increase the air intake to achieve air cooling and rapid heat dissipation of the battery compartment.

[0042] The grille opening 32 and the grille baffle 33 obliquely disposed on the grille opening 32 form a grille opening that is connected to the heat dissipation passage 2 .

[0043] In order to ensure that the battery compartment has a good air intake, the angle formed between the grille baffle 33 and the corresponding grille opening 32 is 20 ° ~70 ° By limiting the angle formed between the grille baffle 33 and the grille opening 32, the size of the grille opening can be reasonably set so that the air intake into the battery compartment reaches a better state and the grille baffle 33 has a better blocking effect on rainwater. Figure 2 As shown, the angle formed between the grille baffle 33 and the corresponding grille opening 32 is 45 0 At this angle, the air volume entering the battery compartment reaches an optimal state and the grille baffle 33 has the best effect of blocking rainwater.

[0044] In this specific embodiment, the grille baffle 33 is an arc-shaped grille baffle 33. The surface of the arc-shaped grille baffle 33 is smooth. By setting the grille baffle 33 as a grille baffle 33 with an arc surface, rainwater falls on the grille baffle 33 and slides down directly and quickly, thereby preventing rainwater from entering the battery compartment. Of course, in another specific embodiment, the grille baffle 33 can also be a straight-faced grille baffle 33, which can block rainwater and reduce rainwater from entering the battery compartment.

[0045] In order to increase the air intake, the grille opening 32 is a rectangular grille opening 32. By providing the rectangular grille opening 32, the width of the grille opening 32 is increased, and the area of ​​the grille opening 32 is also increased, which helps wind enter the battery compartment to achieve air cooling and heat dissipation.

[0046] The plurality of grille openings 32 and the corresponding grille baffles 33 are arranged in a square shape on the panel body 31. By arranging the grille openings 32 and the grille baffles 33 in a square shape on the panel body 31, it helps to improve the overall aesthetics of the rotating bus battery compartment heat dissipation grille, making it comfortable for users to watch. Of course, the plurality of grille openings 32 and the corresponding grille baffles 33 can also be arranged in a rectangular shape on the panel body 31.

[0047] In this specific embodiment, the rotary drive device 4 is connected to the battery compartment door 1 through a support rod 5. Specifically, the support rod 5 includes a first bending portion 51, a connecting rod 52 and a second bending portion 53; one end of the first bending portion 51 is connected to the battery compartment door 1; the other end is connected to one end of the connecting rod 52; the other end of the connecting rod 52 is connected to the second bending portion 53; the second bending portion 53 is located at the center of the heat dissipation vent 2 and is connected to the rotary drive device 4. The provision of the support rod 5 helps to fix the rotary drive device 4, facilitates the connection between the rotary drive device 4 and the grille panel 3, controls the rotation and locking of the grille panel 3, and realizes the change of the opening direction of the grille panel 3. Among them, two wires can be connected from the rotary drive device 4 in the support rod 5, one is responsible for signal reception, and the other is connected to the power supply. The support rod 5 is composed of a first bending portion 51, a connecting rod 52 and a second bending portion 53. The first bending portion 51 is used to connect to the battery compartment door 1. Under the effect of bending, the connecting rod 52 can maintain a certain distance from the battery compartment door 1 to avoid the structure between the support rod 5 and the battery compartment door 1 being too tight. Then, it is connected to the connecting rod 52 through the first bending portion 51, so that the connecting rod 2 can extend to the center of the heat dissipation vent 2, and then connected to the second bending portion 53. It is connected to the rotation drive device 4 through the second bending portion 53 to support and fix the rotation drive device 4, which helps to control the rotation and locking of the grille panel 3 to change the opening direction of the grille panel 3.

[0048] The present application also provides an automatic rainproof wind-increasing heat dissipation control method, which is implemented by using the above-mentioned rotating bus battery compartment heat dissipation grille. Figure 8 , the specific steps are as follows:

[0049] S1. Receive the grille rotation mode command selected by the driver;

[0050] S2. According to the above-mentioned grille rotation mode command, a grille panel 3 angle rotation command is issued to the rotation drive device 4;

[0051] S3. The rotation drive device 4 executes the above-mentioned angle rotation instruction of the grille panel 3, and drives the grille panel 3 to rotate and lock.

[0052] In the present application, different grille position buttons are arranged on the function keyboard of the cab of the electric bus, such as "sunny mode", "rainy mode", "rainstorm mode", "windward 45 degree mode", "windward 30 degree mode", etc. Different grille position buttons can control the grille panel 3 to rotate to different angles, change the opening direction of the grille panel 3, and realize different grille rotation modes.

[0053] In step S1, the grille rotation mode instruction means that after the driver makes a judgment based on the weather outside the cab, he presses the corresponding grille gear button on the function keyboard in the cab. After pressing the corresponding grille gear button, a grille rotation mode instruction is sent to the electric bus control unit;

[0054] In step S2, after receiving the grille rotation mode command selected by the driver, the electric bus control unit determines the rotation angle of the grille panel 3 driven by the corresponding rotation drive device 4 in the grille rotation mode, and then issues an angle rotation command for the grille panel 3;

[0055] In step S3, the rotation drive device 4 receives the angle rotation instruction of the grille panel 3, and executes the angle rotation instruction of the grille panel 3, controls the rotation angle of the grille panel 3, and changes the opening direction of the grille panel 3 to achieve different grille rotation modes.

[0056] In "Sunny Mode", if Figure 3 ,Should Figure 3 The arrow in the attached figure indicates the direction of air relative to the electric bus. The weather outside the cab is sunny. The rotating drive device 4 controls the grille panel 3 to rotate vertically and the grille opening faces the wind. This will greatly increase the air intake in the battery compartment. The heat discharged from the battery box will be carried out of the battery compartment by the air, achieving an air cooling effect.

[0057] In "Rainy Mode", if Figure 4 ,Should Figure 4 The arrow in the attached figure indicates the direction of air relative to the electric bus. The weather outside the cab is rainy. The rotary drive device 4 controls the grille panel 3 to rotate to a horizontal position, with the grille opening facing downward. This can appropriately reduce the entry of rainwater into the cabin, but the air intake will also be reduced.

[0058] In "Rainstorm Mode", if Figure 5 ,Should Figure 5 The arrow in the figure indicates the direction of air relative to the electric bus. The weather inside and outside the cab is heavy rain. The rotary drive device 4 controls the grille panel 3 to rotate to a vertical position with the grille opening leeward, thereby reducing or preventing rain from entering the battery compartment.

[0059] In "45 degree windward mode" and "30 degree windward mode", if Figure 6 and Figure 7 ,Should Figure 6 and Figure 7 The arrow in the figure indicates the direction of air relative to the electric bus. As required, the rotary drive device 4 controls the grille panel 3 to be inclined at a corresponding angle to the horizontal, so that the diversity of grille forms can be achieved.

[0060] To sum up, according to the specific outdoor weather conditions, the driver can control the direction of the grille opening by controlling the rotation of the grille panel 3 in the cab, thereby controlling the air intake into the battery compartment, improving the heat dissipation effect, and achieving a waterproof effect, thereby creating a good working environment for the battery to extend the battery life and improve its safety performance.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, rather than to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present application.
