Description

Technical Field

[0001] This application relates to the technical field of battery replacement for electric wide-body vehicles, and in particular to a dustproof device for a quick-connect connector of a power battery for an electric wide-body vehicle. Background Technology

[0002] With the development of electric wide-body vehicle technology, the energy supply of electric wide-body vehicles is generally divided into two modes: one is the charging mode, but the charging time is relatively long; the other is the battery swapping mode, that is, the depleted battery pack is removed and replaced with a fully charged new battery pack to achieve the purpose of quickly replenishing the power.

[0003] However, for the second mode mentioned above, the connection between the battery pack and the vehicle body requires quick-connect fittings and connectors as the battery swapping interface. Since the battery pack is not always assembled with the vehicle body in the battery swapping mode, the quick-connect fittings are easily contaminated by external pollutants or dust during the storage and transportation of the battery pack. This can affect the performance of the quick-connect fittings and connectors themselves, such as increasing the contact resistance of the power connectors or clogging the liquid cooling connectors. In severe cases, it can even prevent the male and female ends of the quick-connect fittings and connectors from mating, affecting the normal operation of the battery pack and the electric vehicle. Utility Model Content

[0004] To prevent external contaminants and dust from entering the quick-connect connector, this application provides a dustproof device for the power battery quick-connect connector of an electric wide-body vehicle.

[0005] This application provides a dustproof device for the quick-connect connector of the power battery of an electric wide-body vehicle, which adopts the following technical solution:

[0006] A dustproof device for the quick-connect connector of a power battery in an electric wide-body vehicle includes:

[0007] A power battery body, on which a power battery quick-connect connector plug is fixedly installed;

[0008] A power battery support, on which a power battery quick-connect connector socket is fixedly installed;

[0009] A dustproof component is mounted on the power battery bracket and is used to shield the power battery quick-connect connector socket.

[0010] By adopting the above technical solution, in the initial state, the dustproof component covers the power battery quick-connect connector socket to prevent external pollutants and dust from entering the power battery quick-connect connector socket. When it is necessary to connect the power battery quick-connect connector plug to the power battery quick-connect connector socket, the power battery body is placed on the power battery support, and the dustproof component opens the power battery quick-connect connector socket, allowing the power battery quick-connect connector plug to be inserted into the power battery quick-connect connector socket, thus completing the connection between the power battery quick-connect connector plug and the power battery quick-connect connector socket.

[0011] Optionally, the dustproof component includes:

[0012] A dust cover is provided on the power battery quick-connect connector socket;

[0013] A rotating shaft is fixedly mounted on the power battery support.

[0014] A connecting rod, which is V-shaped, is fitted at the bottom of the connecting rod and rotatably mounted on the rotating shaft, and a dust cover is fixedly connected to one end of the connecting rod.

[0015] By adopting the above technical solution, in the initial state, the dust cover is placed on the power battery quick-connect connector socket to prevent external pollutants and dust from entering the power battery quick-connect connector socket. When the power battery quick-connect connector plug needs to be inserted into the power battery quick-connect connector socket, the connecting rod rotates, which in turn drives the dust cover to rotate, opening the power battery quick-connect connector socket and facilitating the insertion of the power battery quick-connect connector plug into the power battery quick-connect connector socket.

[0016] Optionally, a pressure block is fixedly installed on the power battery body;

[0017] A pressure rod is fixedly installed at the end of the connecting rod away from the dust cover.

[0018] By adopting the above technical solution, when the power battery quick-connect connector plug needs to be inserted into the power battery quick-connect connector socket, the power battery body moves closer to the power battery support, the pressure block abuts against the pressure rod, the pressure block pushes the pressure rod to rotate around the pivot, the rotation of the pressure rod in turn drives the connecting rod to rotate around the pivot, the rotation of the connecting rod in turn drives the dust cover to rotate, and the power battery quick-connect connector socket opens, making it convenient for the power battery quick-connect connector plug to be inserted into the power battery quick-connect connector socket.

[0019] Optionally, a torsion spring is fitted on the rotating shaft, one end of the torsion spring is fixedly connected to the power battery support, and the other end of the torsion spring is fixedly connected to the connecting rod.

[0020] By adopting the above technical solution, when the power battery quick-connect connector plug is separated from the power battery quick-connect connector socket, the pressure block and the pressure rod separate. Under the action of the torsion spring, the connecting rod rotates around the pivot. The rotation of the connecting rod drives the dust cover to rotate, so that the dust cover covers the power battery quick-connect connector socket, preventing external pollutants and dust from entering the power battery quick-connect connector socket.

[0021] Optionally, it may also include a positioning component, the positioning component comprising:

[0022] Two positioning holes are provided on the power battery support;

[0023] Two positioning rods are fixedly installed on the power battery body.

[0024] By adopting the above technical solution, when the power battery quick-connect connector plug needs to be inserted into the power battery quick-connect connector socket, the two positioning rods are respectively inserted into the two positioning holes, realizing the quick positioning of the power battery quick-connect connector plug and the power battery quick-connect connector socket, and improving the insertion efficiency of the power battery quick-connect connector socket and the power battery quick-connect connector plug.

[0025] Optionally, the positioning component further includes:

[0026] The telescopic rod has its fixed end fixedly installed in the positioning hole, and its movable end abutting against the positioning rod.

[0027] A buffer spring is sleeved on the telescopic rod, with one end of the buffer spring fixedly connected to the fixed end of the telescopic rod and the other end of the buffer spring fixedly connected to the movable end of the telescopic rod.

[0028] By adopting the above technical solution, the positioning rod is inserted into the positioning hole and abuts against the movable end of the telescopic rod. The buffer spring plays a buffering role on the power battery body, avoiding collision and damage to the power battery body when it comes into contact with the power battery support.

[0029] Optionally, the positioning rod is frustum-shaped, and the diameter of the end of the positioning rod closer to the power battery body is larger than the diameter of the end of the positioning rod farther from the power battery body.

[0030] By adopting the above technical solution, it is convenient to insert the positioning rod into the positioning hole, thereby improving the insertion efficiency of the power battery quick-connect connector socket and the power battery quick-connect connector plug.

[0031] Optionally, rubber pads are fixedly installed at the ends of the power battery body and the power battery support that are close to each other.

[0032] By adopting the above technical solution, collisions that could damage the power battery body can be avoided when it comes into contact with the power battery support.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. In the initial state, the dustproof component covers the power battery quick-connect connector socket to prevent external pollutants and dust from entering the power battery quick-connect connector socket. When it is necessary to connect the power battery quick-connect connector plug to the power battery quick-connect connector socket, the power battery body is placed on the power battery support, and the dustproof component opens the power battery quick-connect connector socket, so that the power battery quick-connect connector plug can be inserted into the power battery quick-connect connector socket, thus completing the connection between the power battery quick-connect connector plug and the power battery quick-connect connector socket.

Rubber pads are fixedly mounted on the adjacent ends of both the power battery body 1 and the power battery support 2. The dustproof component is mounted on the power battery support 2 and is used to shield the power battery quick-connect connector socket 21.

[0052] In the initial state, the dustproof component covers the power battery quick-connect connector socket 21 to prevent external pollutants and dust from entering the power battery quick-connect connector socket 21. When it is necessary to connect the power battery quick-connect connector plug 12 to the power battery quick-connect connector socket 21, the power battery body 1 is placed on the power battery support 2, and the dustproof component opens the power battery quick-connect connector socket 21, so that the power battery quick-connect connector plug 12 can be inserted into the power battery quick-connect connector socket 21, thus completing the connection between the power battery quick-connect connector plug 12 and the power battery quick-connect connector socket 21.

[0059] The positioning rod 42 is inserted into the positioning hole 41 and abuts against the movable end of the telescopic rod 43. The buffer spring 44 plays a buffering role on the power battery body 1, so as to avoid collision and damage to the power battery body 1 when it comes into contact with the power battery support 2.

[0060] The implementation principle of the dustproof device for the power battery quick-connect connector of the electric wide-body vehicle in this application embodiment is as follows: In the initial state, the dustproof component covers the power battery quick-connect connector socket 21 to prevent external pollutants and dust from entering the power battery quick-connect connector socket 21.
