[0002] The anti-vibration battery safety latch is a safety latch designed to enhance the shock resistance of battery packs. Typically installed on the battery compartment door, its latch structure ensures the door remains closed despite vibration or impact, protecting the battery pack interior from damage. This latch design not only enhances battery pack safety but also extends its service life. The use of anti-vibration battery safety latches is particularly important in specific applications, such as electric vehicles and energy storage systems, to ensure stable operation of battery packs under various complex operating conditions.

[0003] Existing battery lock buckles usually adopt a single-layer protection solution. However, in an environment with severe vibration, once the single-layer locked battery lock buckle falls off, a large amount of tiny stones and rainwater will enter the battery compartment. The friction between the stones due to vibration will cause battery leakage or even fire, greatly increasing safety hazards and economic losses. Utility Model Content

[0004] In order to overcome the problem that once the single-layer locked battery lock falls off, a large amount of tiny stones and rainwater will enter the battery compartment. The friction caused by the stones between the battery packs due to vibration will cause battery leakage or even fire, greatly increasing safety hazards and economic losses.

[0005] The technical solution of the present utility model is: a seismic-resistant battery safety lock, comprising an integrally formed lock component 1, a lock component 2, and a lock component 3, the lock component 1 comprising an insertion shaft, the lock component 2 comprising an insertion tube, the insertion tube being axially provided with a through hole, the insertion tube being radially provided with a hole 1, the insertion shaft being radially provided with a hole 2, when the insertion shaft is inserted into the through hole, the hole 1 and the hole 2 can be aligned, the lock component 3 can be inserted into the hole 1 and the hole 2, the lock component 3 and the lock component 1 are connected by a connecting belt A; the lock component 1 and the lock component 2 are connected by a connecting belt B, and the lock component 2 is located between the lock component 1 and the lock component 3.

[0006] Preferably, by inserting the locking member 1 into the locking member 2, a fixing ring is formed between the locking member 1, the locking member 2 and the connecting belt B. Figure 6A loop is formed by the connecting belt B on the left side, which is fixed on the top of the battery compartment through this fixing loop to prevent the battery compartment from being opened and intruding sand and rainwater to cause damage to the battery. Thanks to the structure of hole one, hole two and locking part three, the structure has shock resistance, so that it cannot be easily shaken open. The existing battery compartment usually places the power supply inside and connects the power supply in series, where the positive pole of the first battery is connected to the positive terminal on the outside of the battery compartment, and the negative pole of the last battery is connected to the negative terminal on the outside of the battery compartment. The battery compartment here is existing technology and the specific structure will not be repeated.

[0007] Preferably, a block 1 is provided on one side of the insertion shaft for inserting the insertion tube, and the block 1 is provided with a notch 1. The side of the notch 1 away from the insertion shaft is opening 1, and the side of the notch 1 close to the insertion shaft is opening 2. The opening 1 is larger than the opening 2. Pinching the block 1 can reduce the size of the notch 1. When the notch 1 is reduced, the block 1 can pass through the perforation. By pinching the deformed block 1, the block 1 can be inserted into the perforation. After the block 1 passes through the perforation, the block 1 relaxes, so that the block 1 cannot fall off from the locking piece 2. Pinching here refers to pinching the block 1 with your hands to reduce the opening 1. It can also refer to the block 1 being squeezed by other objects to reduce the opening 1.

[0008] Preferably, the block 1 has a slope on the side away from the insertion axis, and the block 1 has a plane 1 on the side close to the insertion axis. The insertion axis is perpendicular to the plane 1. The slope allows the block 1 to slide easily into the through hole, and the plane 1 can prevent the block 1 from sliding out of the through hole at will, thereby forming a first seismic-resistant structure.

[0009] Preferably, a block two is provided on one side of the insertion tube, the block two includes a through hole for passing through the block one, the block two is provided with a notch two, the side of the block two away from the insertion tube is a plane two, the plane one can fit with the plane two, and the plane two cooperates with the plane one, and the plane one and the plane two are in contact with each other, so that the plane two presses against the plane one to prevent the block one from sliding down.

[0010] Preferably, the locking component three includes a pin shaft, one end of which is connected to the connecting belt A, and the other end is provided with a block three, and the block three includes two integrally formed expanding wings, which can be fitted on the block three. The expanding wings here refer to the barbs at the block three pointing to the direction of the pin shaft at a certain angle. When the locking component three is inserted into the hole one and the hole two, the expanding wings can prevent the pin shaft from falling off from the hole one and the hole two, thereby forming a second seismic structure.

[0011] Preferably, the locking piece 1, locking piece 2, locking piece 3 and connecting belt A and connecting belt B are made of polypropylene drawing grade resin. Thanks to the advantages of polypropylene drawing grade resin such as strong breaking strength, bending resistance and corrosion resistance, the device is more durable and has a longer service life.

[0012] Preferably, the thickness of the connecting belt A and the connecting belt B is two millimeters. Since the connecting belt A and the connecting belt B need to be bent, the connecting belt A and the connecting belt B here are two millimeters thick, which can provide a certain toughness to prevent breakage while being easy to bend.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figures 1-6The present invention provides an embodiment: a seismic-resistant battery safety lock, comprising an integrally formed lock component 1, a lock component 2, and a lock component 3, wherein the lock component 1 comprises an insertion shaft 11, the lock component 2 comprises an insertion tube 21, the insertion tube 21 is axially provided with a through hole 211, the insertion tube 21 is radially provided with a hole 1 212, the insertion shaft 11 is radially provided with a hole 2 111, when the insertion shaft 11 is inserted into the through hole 211, the hole 1 212 and the hole 2 111 can be aligned, the lock component 3 can be inserted into the hole 1 212 and the hole 2 111, the lock component 3 3 and the lock component 1 are connected by a connecting belt A401; the lock component 1 and the lock component 2 are connected by a connecting belt B402, and the lock component 2 2 is located between the lock component 1 and the lock component 3 3. By inserting the locking member 1 into the locking member 2 2, a fixed loop is formed between the locking member 1, the locking member 2 2 and the connecting belt B402, and the fixing loop is set on the top of the battery compartment to prevent the battery compartment from being opened and intruding sand, mud and water to cause damage to the battery. Thanks to the structure of the hole 1 212, the hole 2 111 and the locking member 3 3, the structure has shock resistance and cannot be easily shaken open. The existing battery compartment usually places a power supply inside and connects the power supplies in series, wherein the positive pole of the first battery is connected to the positive terminal on the outside of the battery compartment, and the negative pole of the last battery is connected to the negative terminal on the outside of the battery compartment. The battery compartment here is existing technology and the specific structure is not repeated.

[0024] See also Figure 1-Figure 5In this embodiment, a block 12 is provided on one side of the insertion shaft 11 for inserting the insertion tube 21. The block 12 is provided with a notch 121. The side of the notch 121 away from the insertion shaft 11 is an opening 1211, and the side of the notch 121 closer to the insertion shaft 11 is an opening 2 1212. The opening 1211 is larger than the opening 2 1212. Pinching the block 12 can reduce the size of the notch 121. When the notch 121 is reduced, the block 12 can pass through the through-hole 211. By pinching the deformable block 12, the block 12 can be inserted into the through-hole 211. After the block 12 passes through the through-hole 211, the block 12 relaxes, preventing the block 12 from falling off the locking member 2 2. Pinching here refers to manually pinching the block 12 to reduce the opening 1211. It can also refer to the block 12 being squeezed by other objects to reduce the opening 1211. Block 12 has a sloped surface 122 on the side facing away from the insertion shaft 11, and a flat surface 123 on the side facing the insertion shaft 11. The insertion shaft 11 is perpendicular to flat surface 123. Slope 122 allows Block 12 to slide easily into through-hole 211, while flat surface 123 prevents Block 12 from sliding out of through-hole 211, forming a first layer of earthquake resistance. Block 213 is provided on one side of the insertion tube 21. Block 213 includes a through-hole 2131 for passing Block 12. Block 213 is also provided with a notch 2132. Block 213 has a flat surface 2133 on the side facing away from the insertion tube 21. Flat surface 123 is adapted to fit into Flat surface 2133. Compatible with Flat surface 123 is Flat surface 2133. Flat surface 123 and Flat surface 2133 contact each other, allowing Flat surface 2133 to press against Flat surface 123, preventing Block 12 from sliding out. The third locking member 3 includes a pin 31, one end of which is connected to the connecting strap A401, and the other end is provided with a third block 32. The third block 32 includes two integrally formed wings 321, which fit snugly against the third block 32. The wings 321 here refer to the barbs on the third block 32 that point at a certain angle toward the pin 31. When the third locking member 3 is inserted into the first hole 212 and the second hole 111, the wings 321 prevent the pin 31 from falling out of the first hole 212 and the second hole 111, forming a second anti-seismic structure.

[0025] See also Figure 1In this embodiment, the locking member 1, locking member 2, locking member 3, and connecting bands A401 and B402 are made of polypropylene wire drawing grade resin. Thanks to the advantages of polypropylene wire drawing grade resin, such as strong breaking strength, bending resistance, and corrosion resistance, the device is more durable and has a longer service life. The thickness of the connecting bands A401 and B402 is two millimeters. Because the connecting bands A401 and B402 need to be bent, the connecting bands A401 and B402 are both two millimeters thick, which makes them easy to bend while providing a certain degree of toughness to prevent breakage.

[0026] When working, the battery compartment used here has a accommodating compartment and an upper cover, and the accommodating compartment and the upper cover are connected by a hinge, wherein the upper cover is provided with a fixing hole three on the side away from the hinge, and the accommodating compartment is provided with a fixing hole four corresponding to the fixing hole three. The structure of the battery compartment here is the existing technology and will not be repeated here. First, the locking piece 2 is passed through the fixing hole three and the fixing hole four, and then the insertion shaft 11 of the locking piece 1 is inserted into the through hole 211 of the locking piece 2. At this time, the opening 1211 of the block 12 will be affected. The through hole 211 is squeezed and shrunk. At this time, the locking piece 1 is pushed into the locking piece 2 2 until the block 12 is completely pushed out of the through hole 211. The block 12 pushed out of the through hole 211 will stretch and open, and the opening 1211 will restore to its original size. The plane 123 of the block 12 is pressed against the plane 2133 of the block 213 and cannot fall off. At the same time, the hole 211 is also aligned with the hole 1 212. The locking piece 3 is passed through the hole 2 111 and the hole 1 212. The wings 321 are first unfolded and pressed against the hole 21 2 is squeezed and deformed, and the wings 321 are close to the block 32. When the pin 31 completely passes through the second hole 111 and the first hole 212, the wings 321 are expanded and stretched. The wings 321 can resist the insertion tube 21 to prevent the pin 31 from falling off from the hole 212. In this way, two layers of protection are formed for the batteries in the battery compartment, and the device will not fall off when it is shaken. When the device needs to be disassembled, the wings 321 are pinched by hand to push the pin 31 out of the lock piece 1 and the lock. Piece 2 2, then use your hands to pry open the notch 2132 to enlarge the through hole 2131, and at the same time pinch the block 12 to shrink the opening 1211. At this time, you can push the block 12 out of the through hole 211, and the disassembly is completed. Compared with traditional cable ties, this device has the characteristics of easy disassembly. In addition, you can also use scissors to cut the connecting belt A401 and the connecting belt B402 to complete the disassembly. The device may reduce the seismic effect if used again after disassembly. The specific usage depends on the degree of deformation of the device.

[0027] Through the above steps, by inserting the lock fastener 1 into the lock fastener 2, a fixed loop is formed between the lock fastener 1, the lock fastener 2 and the connecting belt B402. Figure 6A loop formed by the left connecting belt B402 is fixed on the top of the battery compartment through this fixing loop to prevent the battery compartment from being opened and the intrusion of sand and rainwater to cause damage to the battery. Thanks to the structure of the hole 1 212, the hole 2 111 and the locking part 3, the structure has shock resistance and cannot be easily shaken open, so as to solve the problem that once the single-layer locked battery lock falls off, a large amount of tiny stones and rainwater will enter the battery compartment. The friction caused by the stones between the battery packs due to vibration will cause battery leakage or even fire, greatly increasing safety hazards and economic losses.
