Description

Technical Field

[0001] This utility model relates to the field of battery compartments, and more specifically, to a waterproof, ventilated and drained structure for battery compartments. Background Technology

[0002] Electric vehicles (EVs) are cars that use an electric motor as their power source, powered by batteries or other energy storage devices to drive their wheels. EVs can be charged by external power sources, such as the power grid or charging stations, or by an onboard generator (as in hybrid vehicles) or a fuel cell (as in hydrogen fuel cell vehicles). The batteries are typically lead-acid batteries, which have high capacity, high discharge power, and a long lifespan. The battery compartment is the part designed to house and secure the batteries; it not only provides storage space but also ensures the stability and safety of the batteries during use.

[0003] For example, application number CN202021847577.3 discloses an electric forklift that facilitates battery pack replacement. The electric forklift can easily replace the battery pack module, enabling continuous operation and improving its working capacity. The ventilation holes can be used for ventilation and heat dissipation of the battery compartment. The above device solves the problem of easy battery pack replacement. However, because it is easy to replace the battery pack, the battery compartment needs to be opened frequently, which can easily lead to poor sealing of the battery compartment. When using an electric vehicle, it is necessary to ensure that the battery compartment has good sealing and also to prevent water from entering the battery compartment.

[0004] Therefore, a waterproof, ventilated, and drained structure for the battery compartment is proposed to address the above issues. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof, ventilated and drained battery compartment structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof ventilation and drainage structure for a battery compartment, comprising an electric vehicle body, a battery compartment, a vent, a groove, and a waterproof ventilation and drainage plate. The battery compartment is excavated on the bottom end face of the electric vehicle body, and a vent is provided through the bottom end face of the battery compartment. A groove is provided on one side below the vent, and a bolt groove is provided on the inner side of the groove. The groove is bolted and connected to the waterproof ventilation and drainage plate through the bolt groove. The waterproof ventilation and drainage plate includes a protective shell and a baffle. A limiting groove is excavated on the upper end face of the protective shell, and the protective shell is connected to the baffle through the limiting groove. A first through groove is excavated inside the protective shell, and a second through groove is provided through the upper end face of the baffle. A closing plate is connected to the inner edge of the second through groove through a hinge.

[0007] Preferably, the protective shell and the groove in the waterproof ventilation and drainage board form a bolted connection structure, the battery compartment forms a communication structure with the second through groove through the vent, the vent forms a communication structure with the first through groove through the second through groove, and the closing plate forms a rotation structure around the hinge center through the hinge and the baffle.

[0008] Preferably, the closing plate has a cavity structure, and the closing plate is specifically made of a low-density polyethylene float. A fluororubber plate is provided at the edge of the closing plate, and a sealing gasket is provided at the contact surface between the second through groove and the closing plate.

[0009] Preferably, the contact surface between the side of the closing plate away from the hinge and the inner side of the second through groove is inclined, and the contact surfaces between the three sides of the closing plate and the second through groove are all inclined. A sealing ring is provided on the contact surface between the closing plate and the baffle through the hinge.

[0010] Preferably, the surfaces of the protective shell, baffle, and closing plate are coated with epoxy anti-corrosion coating, and the battery compartment is connected to the first through slot through a vent and a second through slot.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] Compared with existing technologies, this battery compartment waterproof ventilation and drainage structure has a waterproof ventilation and drainage plate installed at the vent on the bottom surface of the battery compartment. The battery compartment is connected to the first channel through the vent and the second channel. Since the contact surfaces of the three sides of the closed plate with the second channel are all inclined, the closed plate can rotate in one direction through the above structure. This device has the effect of ventilation and drainage, and can also prevent water backflow, thus achieving a waterproof effect.

[0013] Compared with existing technologies, this battery compartment waterproof ventilation and drainage structure, during use, involves bolting a waterproof ventilation and drainage plate into a groove below the vent on the lower end face of the battery compartment, thus fixing the plate in place. This bolt-locking structure between the electric vehicle body and the waterproof ventilation and drainage plate achieves ventilation and drainage for the battery compartment, while also preventing backflow of water. This facilitates heat dissipation within the battery compartment and ensures its airtightness. The waterproof ventilation and drainage plate consists of a protective shell, a baffle, a limiting groove, a first through groove, a second through groove, and a closing plate. Since the battery compartment is connected to the first through groove via the vent and the second through groove, it allows for ventilation through the vent... The second and first channels facilitate ventilation and drainage of the battery compartment's interior. Since the contact surfaces of the closing plate and the second channel on three sides are inclined, the rotation angle of the closing plate is limited, preventing backflow of water. The closing plate is specifically made of a low-density polyethylene float, facilitating its rotation. Furthermore, the edges of the closing plate are fitted with fluororubber plates, and the contact surfaces between the second channel and the closing plate are fitted with sealing gaskets. A sealing ring is also provided at the contact surfaces between the closing plate and the baffle via a hinge. These features ensure a tight seal between the closing plate and the second channel when they are closed. Through this structure, the device provides both ventilation and drainage while preventing backflow of water, thus achieving a waterproof effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 3 The battery compartment waterproof ventilation and drainage structure shown includes an electric vehicle body 1, a battery compartment 2, a vent 3, a groove 4, and a waterproof ventilation and drainage plate 5. The battery compartment 2 is excavated on the bottom end face of the electric vehicle body 1, and the vent 3 is provided through the bottom end face of the battery compartment 2. A groove 4 is provided on one side below the vent 3, and a bolt groove is provided on the inner side of the groove 4. The groove 4 is bolted and connected to the waterproof ventilation and drainage plate 5 through the bolt groove. The waterproof ventilation and drainage plate 5 includes a protective shell 51 and a baffle 52. A limiting groove 53 is excavated on the upper end face of the protective shell 51, and the baffle 52 is limited and connected to the protective shell 51 through the limiting groove 53. A first through groove 54 is excavated inside the protective shell 51, and a second through groove 55 is provided through the upper end face of the baffle 52. A closing plate 56 is connected to the inner edge of the second through groove 55 through a hinge.

[0024] Specifically, the waterproof ventilation and drainage plate 5 is bolted to the inner side of the groove 4 below the vent 3 on the lower end face of the battery compartment 2 to fix the waterproof ventilation and drainage plate 5, thus creating a bolt-limited structure between the electric vehicle body 1 and the waterproof ventilation and drainage plate 5. The waterproof ventilation and drainage plate 5 provides ventilation and drainage for the battery compartment 2, facilitates heat dissipation inside the battery compartment 2, and ensures the airtightness of the battery compartment 2. The waterproof ventilation and drainage plate 5 consists of a protective shell 51, a baffle 52, a limiting groove 53, a first through groove 54, a second through groove 55, and a closing plate 56. Since the battery compartment 2 uses the vent 3 and the second through groove 55 to form a communication structure with the first through groove 54, it allows for easy passage through the vent 3, the second through groove 55, and the first through groove 54. The inner cavity of the battery compartment 2 is ventilated and drained. Since the three sides of the closing plate 56 are inclined to the contact surface with the second through groove 55, the rotation angle of the closing plate 56 can be limited to prevent water backflow. The closing plate 56 is made of a low-density polyethylene float, which facilitates the rotation of the closing plate 56. The edges of the closing plate 56 are provided with fluororubber plates, and the contact surface between the second through groove 55 and the closing plate 56 is provided with a sealing gasket. The contact surface between the closing plate 56 and the baffle 52 is provided with a sealing ring. When the closing plate 56 and the second through groove 55 are closed, the sealing between the closing plate 56 and the second through groove 55 is guaranteed. This device has the effect of ventilating and draining water, and can also prevent water backflow, thus having a waterproof effect.

The vent 3 forms a communication structure with the first through groove 54 through the second through groove 55. The closing plate 56 forms a rotating structure around the hinge center with the baffle 52 through the hinge. Since the battery compartment 2 forms a communication structure with the first through groove 54 through the vent 3 and the second through groove 55, the vent 3, the second through groove 55 and the first through groove 54 can be used to facilitate ventilation and drainage of the inner cavity of the battery compartment 2.

[0028] In a preferred embodiment, the closing plate 56 has a cavity structure, and the closing plate 56 is specifically made of a low-density polyethylene float. A fluororubber plate is provided at the edge of the closing plate 56, and a sealing gasket is provided at the contact surface between the second through groove 55 and the closing plate 56, thereby ensuring the sealing between the closing plate 56 and the second through groove 55 when the closing plate 56 and the second through groove 55 are closed.

The battery compartment 2 is connected to the first channel 54 through the vent 3 and the second channel 55 to ensure the service life of the device.

[0031] The working process of this utility model is as follows: First, the waterproof ventilation and drainage plate 5 is installed with bolts inside the groove 4 on one side below the vent 3 on the lower end face of the battery compartment 2, fixing the waterproof ventilation and drainage plate 5, so that the electric vehicle body 1 and the waterproof ventilation and drainage plate 5 are bolted together. Since the battery compartment 2 is connected to the first through groove 54 through the vent 3 and the second through groove 55, the ventilation port 3, the second through groove 55, and the first through groove 54 facilitate ventilation and drainage of the inner cavity of the battery compartment 2. Furthermore, since the contact surfaces of the three sides of the closing plate 56 with the second through groove 55 are all inclined, the… The rotation angle of the closing plate 56 is limited, and since the closing plate 56 is made of a low-density polyethylene float, it is easy for the closing plate 56 to rotate. Furthermore, since the edge of the closing plate 56 is provided with a fluororubber plate, and the contact surface between the second channel 55 and the closing plate 56 is provided with a sealing gasket, and the contact surface between the closing plate 56 and the baffle 52 is provided with a sealing ring through the hinge, when the closing plate 56 and the second channel 55 are closed, the sealing between the closing plate 56 and the second channel 55 is guaranteed.
