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 has been a rapidly developing field in recent years. It provides efficient recharging for electric vehicles by rapidly replacing batteries, making it a crucial support for the new energy vehicle industry. As core facilities, battery swapping stations require complex functions within their battery swapping enclosures, not only meeting the needs of battery storage and replacement but also ensuring operational safety and equipment durability during use.

[0003] Existing battery swap boxes typically use a simple door structure, with opening and closing primarily relying on a mechanical transmission. However, this type of structure presents the following issues: First, existing battery swap box doors lack comprehensive protection. If a vehicle collides with the box due to operational errors, the box and its internal equipment may be damaged. Second, the door opening process fails to protect against accidental vehicle entry. A vehicle entering the box may directly contact partially opened door components, causing equipment damage or accidents. Third, existing door sealing mechanisms are susceptible to external interference, making it impossible to maintain the stability of the sealing plate in the closed state, thus affecting the equipment's protective 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. However, this structure cannot effectively absorb the impact force or achieve automatic reset after the impact, resulting in the protective plate requiring frequent maintenance or replacement, thereby reducing the durability and economy of the equipment. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a new energy battery exchange box with protective functions, 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.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A guide mechanism is provided on the front side of the battery exchange chamber close to the storage slot, and the guide mechanism is used to reset the sealing plate;

[0010] Side protection mechanisms are symmetrically arranged on both sides of the box body, and the side protection mechanisms are used to protect both sides of the box body.

[0011] Furthermore, a tooth groove is horizontally opened 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 room. The driving gear is engaged with the tooth groove, and the driving gear is used to control the opening and closing of the box door mechanism.

[0012] 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 mounting 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.

[0013] Furthermore, multiple groups of card strips are evenly arranged on the lower surface of the control rod, and the multiple groups of card strips correspond to the convex strips one by one. The card strips and the convex strips are staggered, and the convex strips are adapted to the gaps between the two card strips in the same group. 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.

[0014] Furthermore, the guiding mechanism includes a mounting plate fixed to the inner wall of one side of the battery exchange chamber, and two sliding rods slide through the surface of the mounting plate, and mounting heads are provided at the front ends of the two sliding rods.

[0015] 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.

[0016] Furthermore, a second spring is sleeved on the surface of the slide rod, and 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, and the adjusting nut is placed on the rear side of the mounting plate. The adjusting nut is used to adjust the extension distance of the guide wheel.

[0017] 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 protective plate placed on the side of the box body and a slider sliding inside the slide groove. The protective plate is arranged at an angle, and the bottom of the protective plate is placed on the ground. A connecting rod is fixed on the top of the protective plate, and the connecting rod is hinged on the two sliders.

[0018] Furthermore, a buffer spring is sleeved on the surface of the fixing rod, the bottom of the buffer spring is in contact with the lower surface of the slider, and the outer surface of the protective plate is evenly provided with buffer ridges.

[0019] The present invention provides a new energy battery replacement box with a protective function. It has the following beneficial effects:

[0020] The new energy battery exchange box with protective function provided by the present invention has an innovative design of the box door mechanism, a notch groove is set on the door panel, and the notch groove is sealed by a sealing plate. In conjunction with the cross bar and sleeve structure inside the installation groove, the sealing plate has a better sealing effect when the box door is closed. The combined design of the sealing plate with the control rod, the card strip and the convex strip avoids abnormal rotation or displacement of the sealing plate due to external forces by means of a locking limit, 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.

[0021] The guide mechanism utilizes a guide wheel and a slide rod to reset any remaining sealing plates individually. A second spring provides a forward force to the guide wheel, ensuring the correct return of the sealing plates when the door is opened. An adjustment nut allows for flexible adjustment of the guide wheel's extension distance to accommodate varying sealing plate positions. This ensures the sealing plates automatically reset over extended periods of use, resolving the issues of inefficient or manual reset required by conventional sealing plates and further enhancing the device's convenience and flexibility.

[0022] The side protection mechanism, through a combination of a protective plate, slider, and buffer spring, provides effective buffering protection against side impacts. Initially, the protective plate is tilted, with its bottom touching the ground. Upon a slight impact, the plate gradually becomes vertical and, through the slider, compresses the buffer spring, achieving a primary buffering effect. In the event of a stronger impact, the plate completely adheres to the side of the box, and the outer buffer ribs deform to provide a secondary buffer, further protecting the box and its internal equipment. This solves the problem of existing box side protection structures being unable to effectively absorb impact forces and unable to automatically reset after damage, extending the device's service life and improving its safety and reliability.

[0023] 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.

[0049] Example 2: Optimization experiment of door panel sealing performance

[0050] Working principle:

[0051] For the notch groove 22 of the door panel 21, through the crossbar 25 and the shaft sleeve 26 structure inside the installation groove 24, multiple sealing plates 28 can cooperate with each other through the control rod 29, the card 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 , with high elasticity and wear resistance, ensuring that it is not easy to age during long-term use. The design size of the mounting groove 24 is 10mm in width and 8mm in depth, which cooperates with the insertion portion of the sealing plate 28.

[0052] Experimental data

[0053] The sealing performance under different environments was tested experimentally, and the sealing effect of the limited design of the sealing plate 28 was compared with the sealing effect of the traditional design without limited design. The experimental conditions are as follows:

[0054] Temperature range: to

[0055] Relative humidity: 50%-90%;

[0056] External shock pressure: 0.5 MPa.

[0057]

[0058] Experimental results analysis

[0059] 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.

[0060] Example 3: Optimization experiment of sealing plate reset ability

[0061] How it works

[0062] The guide mechanism 3 resets the sealing plate 28 via a guide wheel 34 mounted at the front end of the slide bar 32. The guide wheel 34 is made of wear-resistant nylon (model: MC901, diameter 50mm), the slide bar 32 is made of stainless steel (model: 304SS), and a second spring 35 is mounted on the surface. The spring length is 30mm and the elastic coefficient is The adjusting nut 36 is used to precisely control the extension distance of the guide wheel 34 to ensure that the sealing plates 28 are reset one by one.

[0063] Experimental data

[0064] The guide wheel reset effect was measured at different sealing plate offset angles:

[0065] Offset angle range: to

[0066] Reset distance: 10mm to 50mm;

[0067] Test temperature:

[0068]

[0069] Experimental results analysis

[0070] The guide wheel structure of the present invention still has a high reset success rate when it deviates at a large angle. The reset time is slightly prolonged as the angle increases, but the performance is stable.

[0071] Example 4: Side protection mechanism buffer performance test

[0072] How it works

[0073] The protective plate 41, designed through a combination of a slider 44, a buffer spring 45, and a connecting rod 43, provides primary and secondary cushioning. The protective plate 41 is made of aluminum alloy (model: 6061-T6, thickness: 10mm). The buffer spring 45 is 50mm long and has a spring constant of 20 N / mm. The buffer rib 42 is made of rubber (model: NR-70, hardness: 70A) to absorb large impacts.

[0074] Experimental data

[0075] The cushioning effect of the protective plate 41 was measured under different impact forces:

[0076] Impact force range: 100 N to 500 N;

[0077] Deformation of protective plate: 1mm to 10mm;

[0078] Return time: 0.5s to 2s.

[0079]

[0080] Experimental results analysis

[0081] Experimental data show that the protective plate 41 can effectively return to its original position under a small impact force, and can effectively absorb energy in combination with the buffer ribs 42 under a large impact force. The overall structure has strong impact resistance and excellent reset performance.

[0082] Working principle: The internal motor drives the driving gear 14 to rotate, and then the mutual engagement of 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 presence 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 mounting groove 24. Limiting: 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 backward to activate the buffering effect, thereby protecting 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, closing the box door mechanism 2. The protruding control rod 29 will be squeezed inward 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;

[0083] The guide mechanism 3 can effectively reset the sealing plates 28 that have failed to return to their original position. If any sealing plates 28 are not in a vertical position when the door mechanism 2 is opened, they can be reset one by one by the guidance of the guide wheels 34 when returning to their original position. The guide wheels 34 can squeeze the sealing plates 28, and the second spring 35 can ensure that the guide wheels 34 always have a forward force. The extension distance of the guide wheels 34 can be controlled by rotating the adjustment nut 36, thereby improving the flexibility of the device in practical use.

[0084] The side protection mechanisms 4 on both sides can protect the sides of the box body 1. Due to the presence of the internal buffer spring 45, the slider 44 has a downward force, which then drives the protective plate 41 to the bottom and swings the protective plate 41 to make it in an inclined state, that is, the bottom is tilted 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 upward to squeeze the buffer spring 45, and then play a first-level buffering role to cope with slight impacts. The maximum tilt angle of the protective plate 41 can be controlled by setting a corresponding gear lever between the connecting rod 43 and the slider 44 for easy 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 play the purpose of secondary buffering.

[0085] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
