Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery exchange boxes, and specifically to a new energy battery exchange box with a protective function. Background Art

[0002] New energy battery swapping technology is a rapidly developing technology field in recent years. It achieves efficient energy replenishment by quickly replacing batteries for electric vehicles and is an important support for the new energy vehicle industry. As a core facility, the battery swapping station needs to carry complex functions. It not only needs to meet the needs of battery storage and replacement, but also needs to ensure operational safety and equipment durability during use.

[0003] Existing battery swap boxes usually adopt a simple box door structure, and the opening or closing mainly depends on a mechanical transmission device. However, this type of structure has the following problems in use: First, the box door of the existing battery swap box lacks a complete protection design. When a vehicle hits the box due to an operating error, the box and the internal equipment may be damaged; second, the vehicle's accidental entry protection is not considered during the box door opening process. When the vehicle enters, it may directly contact the box door parts that are not fully opened, causing equipment damage or safety accidents; third, the existing box door sealing device is easily disturbed by external forces, and it is impossible to ensure the stability of the sealing plate in the closed state, thereby affecting the equipment protection performance.

[0004] In addition, in order to cope with possible impacts on the side of the box, traditional designs often use a fixed protective plate structure, but this structure cannot effectively absorb the impact force or achieve automatic reset after the impact, resulting in the need for frequent maintenance or replacement of the protective plate, thereby reducing the durability and economy of the equipment. Summary of the invention

[0005] In response to the shortcomings of the prior art, the present invention provides a new energy battery exchange box with protective function, which can effectively protect the box from various safety hazards during use, including vehicle accidental entry protection, stability of the box door sealing plate and buffering protection performance of the box side, so as to improve the overall equipment safety and reliability, while enhancing the equipment's flexibility and durability.

[0007] Furthermore, a tooth groove is transversely provided on the inner wall of the door panel, and a driving gear is installed on the side of the front surface of the storage groove close to the battery exchange chamber. The driving gear is meshed with the tooth groove, and the driving gear is used to control the opening and closing of the box door mechanism.

[0008] Furthermore, a convex strip is provided on one side of the upper surface of the shaft sleeve, and a control rod is slidably installed inside the installation groove. The control rod is placed parallel to the cross bar, and the end of the control rod exceeds the side of the door panel.

[0009] Furthermore, a plurality of groups of clamping strips are evenly arranged on the lower surface of the control rod, and the plurality of groups of clamping strips correspond to the convex strips one by one, and the clamping strips and the convex strips are staggered, and the convex strips are adapted to the gap between two clamping strips in the same group, and a first spring is installed on the inner side of the mounting groove, and one end of the first spring is in contact with the inner end surface of the control rod.

[0010] Furthermore, the guiding mechanism includes a mounting plate fixed to an inner wall of one side of the power exchange chamber, two sliding rods slidingly penetrate the surface of the mounting plate, and mounting heads are provided at the front ends of the two sliding rods.

[0011] Furthermore, a guide wheel is rotatably mounted on the front end of the mounting head, the axis of the guide wheel is vertically arranged, the position of the guide wheel corresponds to the sealing plate, and the guide wheel is used to reset the sealing plate when the door is closed.

[0012] Furthermore, a second spring is sleeved on the surface of the slide rod, the second spring is placed between the mounting head and the mounting plate, an adjusting nut is screwed on the surface of the slide rod, the adjusting nut is placed on the rear side of the mounting plate, and the adjusting nut is used to adjust the extension distance of the guide wheel.

[0013] Furthermore, slide grooves are symmetrically opened on both sides of the box body, and fixed rods are vertically arranged inside the slide grooves. The side protection mechanism includes a protection plate placed on the side of the box body and a slider sliding inside the slide groove. The protection plate is tilted and the bottom of the protection plate is placed on the ground. A connecting rod is fixed on the top of the protection plate, and the connecting rod is hinged on two sliders.

The combined design of the sealing plate, the control rod, the clamping strip and the convex strip avoids abnormal rotation or displacement of the sealing plate due to external force by means of clamping and limiting, effectively improving the safety and stability after the box door is closed, thereby solving the problem of unreliable sealing of the existing box door, and further improving the sealing performance and protective effect of the battery exchange box.

[0016] The guide mechanism uses the guide wheel and the slide rod structure to reset the sealing plates that have not returned to their original positions one by one, and the second spring provides the guide wheel with a forward force to ensure the correct reset of the sealing plate when the door panel is opened. The setting of the adjustment nut allows the extension distance of the guide wheel to be flexibly adjusted to adapt to the position of different sealing plates, thereby realizing the automatic reset function of the sealing plate in long-term use, solving the problem of low reset efficiency or manual adjustment of traditional sealing plates, and further enhancing the convenience and flexibility of the device.

[0017] The side protection mechanism can provide effective buffer protection when the side is hit by a combination of a protective plate, a slider and a buffer spring. The protective plate is tilted in the initial state, with the bottom touching the ground. When it is slightly hit, the protective plate gradually tends to be vertical and squeezes the buffer spring through the slider to achieve a primary buffer effect; when the impact is strong, the protective plate completely fits the side of the box vertically, and the outer buffer convex strips provide secondary buffering through deformation, further protecting the box and internal equipment, solving the problem that the existing box side protection structure cannot effectively absorb the impact force and cannot automatically reset after damage, extending the service life of the device and improving the safety and reliability of the equipment.

[0018] Through overall structural optimization and functional design, the present invention not only improves the sealing performance, protective effect and ease of use of the battery swap box, but also provides comprehensive protection for vehicles that may be hit or misoperated, effectively solving the shortcomings of existing battery swap boxes in terms of safety and durability, and has broad application prospects.

[0031] Example 2: Optimization experiment of door panel sealing performance Working principle: With respect to the notch groove 22 of the door panel 21, through the structure of the cross bar 25 and the shaft sleeve 26 inside the installation groove 24, multiple sealing plates 28 can cooperate with each other through the control rod 29, the clamping strip 210 and the convex strip 27 to achieve limited sealing. The sealing plate 28 is made of silicone rubber material (model: KE-951U, high temperature resistance performance up to to The mounting groove 24 has high elasticity and wear resistance, ensuring that it is not prone to aging during long-term use. The design size of the mounting groove 24 is 10 mm in width and 8 mm in depth, which is matched with the insertion part of the sealing plate 28.

[0032] Experimental data The sealing performance under different environments was tested experimentally, and the sealing effect of the limit design of the sealing plate 28 was compared with that of the traditional design without limit. The experimental conditions are as follows: Temperature range: to

[0033] Relative humidity: 50%-90%; External impact pressure: 0.5 MPa.

[0034]

[0035] Experimental results analysis Comparative data show that the leakage rate of the group of the present invention is significantly reduced, the sealing recovery time is shorter, and the durability is greatly improved, which proves the effectiveness of the limiting structure design.

[0036] Example 3: Optimization experiment of sealing plate reset capability How it works The guide mechanism 3 performs a reset operation on the sealing plate 28 through a guide wheel 34 installed at the front end of the slide bar 32.

[0039]

[0040] Experimental results analysis The guide wheel structure of the present invention still has a high reset success rate when it is offset at a large angle, and the reset time is slightly prolonged as the angle increases, but the performance is stable.

[0041] Example 4: Side protection mechanism buffer performance test How it works The protective plate 41 provides primary and secondary buffering effects by combining a slider 44, a buffer spring 45 and a connecting rod 43. The protective plate 41 is made of aluminum alloy (model: 6061-T6, thickness 10mm), the buffer spring 45 is 50mm long and has an elastic coefficient of 20 N / mm; the buffer ridge 42 is made of rubber material (model: NR-70, hardness 70A) to absorb large impact forces.

[0042] Experimental data Under different impact forces, the buffering effect of the protective plate 41 is measured: Impact force range: 100 N to 500 N; Deformation of protective plate: 1mm to 10mm; Return time: 0.5s to 2s.

[0043]

[0044] Experimental results analysis Experimental data show that the protection plate 41 can return to its original position effectively under a small impact force, and can achieve significant energy absorption effect in combination with the buffer ribs 42 under a large impact force. The overall structure has strong impact resistance and excellent reset performance.

[0045] Working principle: The internal motor drives the driving gear 14 to rotate, and then the mutual engagement between the driving gear 14 and the tooth groove 23 can drive the box door mechanism 2 to slide horizontally as a whole to achieve opening or closing. When a vehicle enters, the box door mechanism 2 slides into the storage groove 13, so that the end of the battery exchange room 11 is open. At this time, the vehicle can enter the battery exchange room 11 through the ramp 12 to perform battery exchange. During the opening process, due to the existence of the first spring 211, the control rod 29 always has an outward force. At this time, the end of the control rod 29 exceeds the side of the door panel 21. At this time, the card strip 210 is misaligned with the convex strip 27. At the same time, the sealing plate 28 remains vertical due to its own weight, and the front side is affected by the inner wall of the installation groove 24. Limitation: when the box door mechanism 2 is not fully opened, if a vehicle enters the battery exchange room 11 due to an operational error, the vehicle will first hit the surface of the suspended sealing plate 28, causing the sealing plate 28 to flip backwards to activate the buffering effect and achieve protection for the entire box body 1. After the vehicle leaves, the sealing plate 28 returns to its position due to its own weight. At this time, the convex strip 27 returns to its position just above, and the box door mechanism 2 is closed. The protruding control rod 29 will be squeezed and retracted by one side of the battery exchange room 11 when it is fully closed. At this time, the two card strips 210 in the same group can engage and limit the convex strip 27 to achieve the limitation of multiple sealing plates 28, preventing the sealing plate 28 from rotating when the door panel 21 is in the closed state, thereby preventing illegal entry; The guide mechanism 3 can effectively reset the sealing plate 28 that has failed to return to its original position. If any sealing plate 28 is not in a vertical state when the door mechanism 2 is opened, it can be reset one by one through the guidance of the guide wheel 34 when returning to its original position. The guide wheel 34 can squeeze the sealing plate 28, and the second spring 35 can make the guide wheel 34 always have a forward force, and the extension distance of the guide wheel 34 can be controlled by rotating the adjustment nut 36, thereby improving the flexibility of the device when it is practical. The side protection mechanisms 4 on both sides can protect the sides of the box body 1. Due to the existence of the internal buffer spring 45, the slider 44 has a downward force, which then drives the protective plate 41 to be placed at the bottom, and swings the protective plate 41 to make it in an inclined state, that is, the bottom is inclined outward and the bottom is in contact with the ground. When the side is hit, the protective plate 41 will tend to be vertical due to the impact, and then drive the slider 44 to move up to squeeze the buffer spring 45, and then play a primary buffering role to cope with slight impacts. The maximum inclination angle of the protective plate 41 can be controlled by setting a corresponding gear lever between the connecting rod 43 and the slider 44 to facilitate installation. At the same time, this solution can be reused and can automatically return to its original position after a slight impact. When the impact force is too large, the protective plate 41 will be vertically attached to the side of the box body 1. At this time, the outer buffer ridge 42 can be deformed to achieve the purpose of secondary buffering.
