Description

Technical Field

[0001] The utility model relates to a charging seat used for charging a battery pack in a charging and swapping station, in particular to a charging seat with a protective cover shell, and belongs to the technical field of new energy vehicles. Background Art

[0002] The applicant has previously applied for an electric heavy-duty truck rapid battery swap station with Chinese patent publication number CN219214775U, a rapid transfer battery swap station with Chinese patent publication number CN218431196U, an electric truck side top-mounted battery swap system with Chinese patent publication number CN216761523U, etc., which are battery swap stations specifically used for charging and swapping electric trucks.

[0003] The battery swap station for electric trucks serves electric trucks, which have a poorer working environment than ordinary family cars. The battery pack of an electric truck is exposed to the outside, and dust and rainwater will accumulate on the battery pack. During the battery swap process, water droplets mixed with dust can easily drip down. The charging seat in the battery swap station is set inside the station, so the interface is generally exposed. In this way, when the battery pack falls, there is a certain probability that sewage will drip onto the interface of the charging seat, causing safety risks such as interface short circuit.

[0004] For this reason, it is necessary to provide certain protection for the interface of the charging station; for example, the battery box delivery vehicle charging mechanism with Chinese patent publication number CN217435544U has an openable or closable rain cover specially provided for the interface, which is driven to open and close by a cylinder, thereby achieving better protection effect.

[0005] However, since the above-mentioned rain cover needs a cylinder to control the opening and closing, this requires an additional control system, and needs to be well adapted to the existing control system of the battery swap station. It is necessary to accurately grasp the falling position of the battery pack relative to the charging seat, that is, it cannot be opened too early to avoid sewage dripping into the charging seat, and it cannot be opened too late to avoid the bottom interface of the battery pack from colliding with the rain cover, causing other risks.

[0006] Therefore, in view of the above-mentioned requirements of the charging stand, it is necessary to further improve the structure of the charging stand in order to meet the risk of preventing sewage dripping, and at the same time, it can be opened or closed in time. Utility Model Content

[0007] The purpose of the utility model is to provide a charging stand with a protective cover shell, in which a protective cover shell is arranged above the interface of the charging stand, and the gravity of the falling battery pack is used as the opening power. In the process of the battery pack falling, the cover shell is gradually opened by the falling distance until it is fully opened and the interface is docked; when the battery pack is taken away and raised, the gas spring is used to achieve automatic reset to reach a protective state; the entire protective cover shell structure does not require other dynamic power supply or power access, and is automatically closed or opened as the battery pack rises and falls.

[0008] In order to achieve the above-mentioned utility model object, the utility model provides a charging stand with a protective cover shell, including a battery bracket for receiving and placing a battery pack, an interface board is provided on the battery bracket, and a plurality of interfaces are provided on the interface board;

[0009] A protective cover mechanism is provided in the interface area;

[0010] The protective cover shell mechanism includes a protective plate and an opening and closing driving mechanism; both sides of the protective plate are provided with an opening and closing driving mechanism;

[0011] A support rod is provided at one end of the protective plate, and both sides of the support rod are fixed on the driving rod;

[0012] The drive rod is a "J" shaped component, the top of its arm is fixed to the guard plate;

[0013] The swing arm end of the driving rod is hingedly mounted on the battery bracket through a fixed hinge shaft, and the driving rod can rotate relative to the battery bracket around the fixed hinge shaft along with the protective plate;

[0014] A swing rod is provided, the bottom of the swing rod is hinged to the middle of the driving rod through a first hinge shaft;

[0015] The top of the swing rod is hinged to the adapter plate through a second hinge shaft;

[0016] The adapter plate is connected to the top of the linear self-resetting mechanism.

[0017] As a further improvement of the present utility model, the protective plate is a flat plate;

[0018] When the protective plate is in the closed state, the free end is tilted upward.

[0019] Furthermore, the free end of the protective plate is folded upward to form a baffle.

[0020] As a further improvement of the utility model, the linear self-reset mechanism is a gas spring.

[0021] The cylinder body of the gas spring is fixed on the battery bracket, the spring rod of the gas spring is vertically arranged upward, and the top of the spring rod is connected to the adapter plate.

[0022] Furthermore, the tops of the adapter plates or the linear self-resetting mechanisms on both sides are connected by a connecting rod.

[0023] Furthermore, a collision block is provided on the top of the adapter plate and / or the top of the connecting rod.

[0024] The opening process of the protective cover shell mechanism of the utility model is as follows: as the battery pack falls, the bottom of the battery pack first contacts the impact block, and the impact block is pressed downward by force, which correspondingly drives the adapter plate and the connecting rod to move downward, that is, drives the spring rod to retract vertically downward into the cylinder body; as the adapter plate moves downward, the swing rod is also driven to move downward, and during the downward movement of the swing rod, it swings at the same time, pushing the drive rod to start rotating around the fixed hinge axis, and finally driving the protective plate to flip outward and downward and open. During the whole process, the free end of the protective plate (that is, the baffle) will not be higher than the height of the impact block until the protective plate is fully opened to expose the interface.

[0025] When the battery pack is taken upward, the closing process of the protective cover shell mechanism of the utility model is reversed. Due to the operation of the gas spring, the spring rod is lifted vertically, thereby driving the adapter plate, the connecting rod and the impact block to move upward, and the connecting rod mechanism is reset, so that the protective plate is flipped inward and upward, closed, and finally covers the interface.

[0026] The utility model provides a charging stand with a protective cover shell, adopts a linear self-resetting mechanism such as a gas spring, and combines with a connecting rod mechanism to drive the protective plate. As the battery pack falls, the protective plate is automatically opened to both sides by the downward pressure of the battery pack; and as the battery pack is taken away, the linear self-resetting mechanism resets upward, driving the protective plate to close inward, thereby achieving the purpose of protection.

[0027] The charging stand with a protective cover shell of the utility model is a purely mechanical structure, which is driven by the falling and rising of the battery pack and is automatically opened or closed. It can realize the automatic expansion or closure of the interface part, meet the protection requirements of the electric truck charging and swapping station, and does not require the additional arrangement of electronic control devices, and can conveniently improve and lift the existing structure.

[0039] The overall structure of the charging stand with protective cover of the utility model is as follows Figure 1 As shown, the overall structure is similar to that of a conventional charging stand, including a battery holder 11 for receiving and placing a battery pack; an interface board 12 is generally provided in the middle of the battery holder 11 according to the design of the battery pack, and a plurality of interfaces 13 are provided on the interface board 12; the improvement of the utility model is that a protective cover mechanism 2 is provided in the area of ​​the interface 13; further as shown Figure 2 As shown, the specific structure of the protective cover shell mechanism 2 can be set according to the arrangement of the interface 13. For example, if the interface 13 is arranged in two rows, the protective cover shell mechanism 2 is provided with two opposing protective plates 21, and correspondingly, two sets of opening and closing drive mechanisms are provided.

[0040] The opening and closing driving mechanism of the single set of protective plates 21 of the protective cover shell mechanism 2 can be further referred to Figure 3 , Figure 4 ; The specific opening and closing states, such as Figure 5-Figure 10 shown.

[0041] The protective plate 21 is a flat plate. When in a closed state, the free end is slightly tilted upward, so that the received sewage can be discharged to the driving end; further, the free end of the protective plate 21 is folded upward to form a baffle 211, which further prevents sewage from dripping from the free end located above the interface 13.

[0042] One end of the protective plate 21 is fixed on the driving rod 22; the driving rod 22 is a "J"-shaped component, the top of its support arm is fixed to the protective plate 21, and a support rod 212 is provided at the fixed end of the protective plate 21, and both ends of the support rod 212 are fixedly connected to the top of the support arm of the driving rod 22.

[0043] The swing arm end of the driving rod 22 is hingedly mounted on the battery holder 11 via a fixed hinge shaft 221, so that the driving rod 22 can rotate around the fixed hinge shaft 221, thereby driving the protective plate 21 to rotate, thereby realizing the protective plate 21 rotating outward to open, or rotating the protective plate 21 inward to close.

[0044] The middle of the driving rod 22 is connected to the swing rod 23 through the first hinge shaft 231, and the bottom of the swing rod 23 is hinged to the driving rod 22 through the first hinge shaft 231; the top of the swing rod 23 is hinged to the adapter plate 24 through the second hinge shaft 232; the adapter plate 24 is connected to the self-resetting mechanism. In the utility model, the self-resetting mechanism is a gas spring 26, the cylinder body 261 of the gas spring 26 is fixed on the battery holder 11, and the spring rod 262 of the gas spring 26 is vertically arranged upward, and the top of the spring rod 262 is connected to the adapter plate 24.

[0045] The opening and closing drive mechanism of each set of protective plates 21 is provided with the same drive rod 22, swing rod 23, adapter plate 24, and gas spring 26 on both sides of the protective plate 21. The adapter plates 24 on both sides are connected by a connecting rod 27, thereby realizing synchronous action on both sides, so that the protective plate 21 can be opened or closed more smoothly.

[0046] A bump block 25 is provided on the top of the adapter plate 24 and / or the connecting rod 27. The position of the bump block 25 is set according to the structure of the bottom of the battery pack, and the contact area between the protective cover shell mechanism 2 and the battery pack is increased.

[0047] Combination Figure 6 , Figure 7 , Fig.10 The opening process of the protective cover shell mechanism 2 of the utility model is as follows: as the battery pack falls, the bottom of the battery pack first contacts the impact block 25, and the impact block 25 is pressed downward by force, which correspondingly drives the adapter plate 24 and the connecting rod 27 to move downward, that is, drives the spring rod 262 to retract vertically downward into the cylinder body 261; as the adapter plate 24 moves downward, the swing rod 23 is also driven to move downward. During the downward movement of the swing rod 23, it swings at the same time, pushing the drive rod 22 to start rotating around the fixed hinge shaft 221, and finally drives the protective plate 21 to flip outward and downward and open. During the whole process, the free end of the protective plate 21 (that is, the baffle 211) will not be higher than the height of the impact block 25 until the protective plate 21 is fully opened to expose the interface 13.

[0048] When the battery pack is taken upward, the closing process of the protective cover shell mechanism 2 of the utility model is reversed. Due to the operation of the gas spring 26, the spring rod 262 is lifted vertically, thereby driving the adapter plate 24, the connecting rod 27, and the impact block 25 to move upward, and the connecting rod mechanism is reset, so that the protective plate 21 is flipped inward and upward, closed, and finally shielding the interface 13.
