Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a battery replacement locking structure for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that are completely powered by rechargeable batteries (or other unconventional vehicle fuels). The batteries provide electrical energy to the electric motors to drive the motors and thus propel the vehicle. They integrate advanced technologies in vehicle power control and drive to form vehicles with new technologies and new structures. When the battery of a new energy vehicle is dead, in order to save time, the battery is generally replaced directly at a battery swap station. The battery is fixed to the bottom of the vehicle with multiple bolts. When the battery is removed, the battery fixing bolts are removed through the mechanical device of the battery swap station, and then the new battery is fixed to the bottom of the vehicle with bolts. The vehicle will experience various road conditions and vibrations during driving, which may cause the bolts to loosen over a long period of time. Once the bolts are loose, the battery will no longer be firmly fixed, which will affect the stability and safety of the battery. In addition, when the bolts are frequently tightened and loosened, the bolts will be severely worn, and the tightening force of the worn bolts will decrease, which will cause the battery pack to move and shake due to bumps, acceleration, deceleration, etc. during vehicle driving.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-Figure 9 , which is the first embodiment of the present invention, and this embodiment provides a new energy vehicle battery replacement locking structure. The new energy vehicle battery replacement locking structure includes a main body component 100, including a frame chassis 101 and a battery pack 102, and the battery pack 102 is arranged in the frame chassis 101.

[0035] The frame chassis 101 is the chassis of the new energy vehicle, which is used to install the battery pack 102. The battery pack 102 is used to provide a power source for the new energy vehicle. This is a prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0036] The locking assembly 200 is disposed on the main assembly 100, and includes a fixed block 201a, a fixed rod 201b, a stopper 201c, a buffer pad 201d, a locking block 201e, an extrusion block 201g, a rotating column 201h and a fixed shaft 201i. One side of the fixed block 201a is fixed to the battery pack 102, the fixed rod 201b is fixed in the frame chassis 101, the stopper 201c is fixed to the outside of the fixed rod 201b, and the buffer pad 201d is fixed to the bottom of the stopper 201c and is sleeved on the fixed rod 201b. On the outside, the locking block 201e is located in the fixed rod 201b, the extrusion block 201g is arranged above the locking block 201e, the rotating column 201h is rotatably connected in the fixed rod 201b, the fixed shaft 201i is fixed in the extrusion block 201g, and a spiral groove 201h-1 is provided on the rotating column 201h, and the fixed shaft 201i slides in the spiral groove 201h-1. One side of the top of the locking block 201e is inclined, and the inclined surface of the locking block 201e contacts the bottom of the fixed block 201a, and both sides of the extrusion block 201g are inclined.

[0037] There are multiple groups of locking assemblies 200, which are respectively located on both sides of the battery pack 102. The multiple groups of locking assemblies 200 can improve the stability of the fixation of the battery pack 102. There are two locking blocks 201e, which are respectively located on both sides of the inside of the fixing rod 201b. An inner hexagonal slot is provided at the bottom end of the rotating column 201h, and a rotary wrench can be inserted into the inner hexagonal slot to rotate the rotating column 201h.

[0038] When fixing the battery pack 102, the battery pack 102 is placed in the chassis 101 through the mechanical trolley inside the battery swap station, and the fixing block 201a is sleeved on the outside of the fixing rod 201b. At this time, the battery pack 102 is moved upward so that the fixing block 201a contacts the buffer pad 201d, and then the rotating column 201h is rotated by rotating the wrench. At this time, the fixed shaft 201i will slide in the spiral groove 201h-1, and the two will drive the extrusion block 201g to move downward, so that the oblique surfaces on both sides of the extrusion block 201g squeeze the two locking blocks 201e, thereby pushing the locking block 201e to move to the outside of the fixing rod 201b, and the locking block 201e is The top inclined surface of 01e contacts with the fixed block 201a and squeezes the fixed block 201a, so that the fixed block 201a can move upward and make the contact between the fixed block 201a and the buffer pad 201d more tightly, thereby completing the locking and fixation of the battery pack 102. The buffer pad 201d can buffer and shock the battery pack 102, thereby avoiding the situation where the battery pack 102 is subjected to strong vibration when the new energy vehicle is bumpy. The battery pack 102 is locked and fixed by squeezing and supporting the fixed block 201a by the locking block 201e, which can avoid the situation where the fastening force is reduced during frequent installation and disassembly.

[0039] The fastening assembly 300 is arranged on the locking assembly 200, and includes a gear 301a, a tooth plate 301b, a movable plate 301c, a plug rod 301d and a connecting column 301e. The gear 301a is rotatably connected to the fixed rod 201b through a mounting frame and is sleeved on the outside of the rotating column 201h. The tooth plate 301b is located on one side of the gear 301a and meshes with the gear 301a. The rotating column 201h is provided with a chamber 201h-2, and the movable plate 301c is provided with a plug rod 301d and a connecting column 301e. Plate 301c is located in chamber 201h-2, one end of the rod 301d is fixed to the movable plate 301c, and the other end is inserted into the rotating column 201h, a slot 301a-1 is provided on the gear 301a, the rod 301d is engaged with the slot 301a-1, one end of the connecting column 301e is fixed to the tooth plate 301b, a through slot 201b-1 is provided on the fixed rod 201b, and the connecting column 301e is movably connected to the through slot 201b-1.

[0040] The number of fastening assemblies 300 corresponds to that of locking assemblies 200. The movable plates 301c are arc-shaped and are two in number, respectively located on both sides of the interior of the chamber 201h-2. When the insertion rod 301d is not engaged with the slot 301a-1, the gear 301a and the rotating column 201h are in a separated state. At this time, the rotation of the rotating column 201h will not affect the gear 301a. A guide column is fixed in the fixed rod 201b, and the tooth plate 301b is movably connected to the guide column to support and position the tooth plate 301b.

[0041] When the insertion rod 301d is engaged with the slot 301a-1, the gear 301a is connected to the rotating column 201h through the cooperation of the two. At this time, the gear 301a is limited by the tooth plate 301b, so that the gear 301a cannot rotate, and the rotating column 201h cannot rotate, thereby preventing the extrusion block 201g of the battery pack 102 from moving when it is locked.

[0042] When the tooth plate 301b moves, it drives the gear 301a to rotate, and drives the rotating column 201h to rotate through the gear 301a. When the rotating column 201h rotates, the extrusion block 201g can continue to squeeze the locking block 201e downward, so that the locking block 201e can continue to move outward and squeeze the fixed block 201a upward, so that the fixed block 201a can be more tightly contacted with the buffer pad 201d, thereby increasing the fastening force of the battery pack 102, thereby preventing the battery pack 102 from being displaced or the fixing force from loosening when it is vibrated.

[0043] The trigger assembly 400 is arranged on the fastening assembly 300, and includes a fixing sleeve 401a, a fixing column 401b, an airbag 401c, a connecting tube 401d, a stabilizing sleeve 401e, a piston plate 401f, a sensing ball 401g and a first spring 401h. The fixing sleeve 401a is fixed to the top of the block 201c, the fixing column 401b is fixed to one side of the connecting column 301e, the airbag 401c is located in the fixing sleeve 401a, one end of the connecting tube 401d is fixed to the fixing sleeve 401a and is connected to the airbag 401c, the stabilizing sleeve 401e is fixed to the top of the connecting tube 401d and is connected to the connecting tube 401d, the piston plate 401f is located in the stabilizing sleeve 401e, the sensing ball 401g is arranged on the top of the piston plate 401f, and both ends of the first spring 401h are respectively fixed to the piston plate 401f and the inner bottom wall of the stabilizing sleeve 401e.

[0044] The number of trigger components 400 corresponds to the fastening components 300. The sensing ball 401g has a certain weight. When the new energy vehicle is driving normally, the sensing ball 401g will move downward by its own weight and press the piston plate 401f downward, and then press the first spring 401h through the piston plate 401f, so that the first spring 401h is in a compressed state.

[0045] When the new energy vehicle bumps and produces relatively strong vibrations, the sensing ball 401g will move upward due to the vibration and separate from the piston plate 401f. At this time, the first spring 401h will push the piston plate 401f upward. When the sensing ball 401g moves downward, it will press the piston plate 401f downward again. When the piston plate 401f is moving downward, the gas below it will be transported to the airbag 401c through the connecting pipe 401d. After the gas is injected into the airbag 401c, it will expand and push the fixed column 401b to move, so that the fixed column 401b drives the connecting column 301e to move, so that the tooth plate 301b can be driven to move through the connecting column 301e, so that the new energy vehicle can increase the fastening force of the battery pack 102 when the bumps are severe.

[0046] When the new energy vehicle resumes stable driving, the piston plate 401f and the sensing ball 401g will both reset. At this time, the gas inside the airbag 401c will slowly leak outward, thereby relieving the squeezing of the fixed column 401b, so that the tooth plate 301b can be reset, and the gear 301a and the rotating column 201h can be rotated in the opposite direction to the initial angle, so that the fastening force of the battery pack 102 can be restored to the initial fixed state, thereby reducing the wear of each component and preventing the fixed block 201a from applying a strong squeezing force to the buffer pad 201d for a long time, which will cause damage to the buffer pad 201d and reduce the buffering and shock-resistant effect.

[0047] Example 2

[0048] Reference Figure 1-Figure 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] Specifically, a vent hole 401f-1 is provided on the piston plate 401f, a baffle 402a is hinged to the bottom of the piston plate 401f through a hinge plate, the baffle 402a blocks the vent hole 401f-1, a mounting block 402b is fixed in the connecting pipe 401d, and a blocking block 402c is hinged to the bottom of the mounting block 402b through a hinge plate.

[0050] A stabilizing shaft is fixed inside the baffle 402a, and the stabilizing shaft is movably connected to the hinge plate. A torsion spring is fixed outside the stabilizing shaft, and one end of the torsion spring is fixed to the hinge plate. After the baffle 402a is opened, it can be reset and closed by the torsion spring.

[0051] When the piston plate 401f moves upward, the generated air flow will push the baffle 402a downward to open through the air hole 401f-1, so that gas can be injected from the bottom of the piston plate 401f. When the piston plate 401f moves downward, the baffle 402a will block the air hole 401f-1, so that the gas below cannot flow outward, and will be compressed by the piston plate 401f and pushed into the connecting pipe 401d. At this time, the gas will push the blocking block 402c downward to open it, so that the gas can enter the interior of the airbag 401c and cause the airbag 401c to expand.

[0052] When the piston plate 401f moves upward, the blocking block 402c will be pushed upward by the gas below and fit with the mounting block 402b, thereby temporarily blocking the gas inside the airbag 401c to prevent the gas inside the airbag 401c from being released outward too quickly. As the piston plate 401f continues to move up and down, the airbag 401c can be quickly inflated.

[0053] When the piston plate 401f stops moving and stops injecting gas into the airbag 401c, the gas inside the airbag 401c will be slowly released outwards.

[0054] Specifically, a limiting rod 402d is fixed to one side of the bottom of the mounting block 402b, and the limiting rod 402d is L-shaped.

[0055] When the blocking block 402c opens downward to a certain angle, it will contact the limiting rod 402d, so that the blocking block 402c can be limited by the limiting rod 402d to prevent the blocking block 402c from opening downward at too large an angle, thereby causing the gas below to be unable to push the blocking block 402c to close upward.

[0056] Specifically, a force-bearing plate 403a is fixed to one end of the fixing column 401b, and one side of the force-bearing plate 403a is in contact with the airbag 401c.

[0057] The force-bearing plate 403a is movably connected to the fixing sleeve 401a, and the contact area between the airbag 401c and the fixing column 401b is increased by the force-bearing plate 403a.

[0058] Specifically, the second spring 403b is fixed to one side of the force-bearing plate 403a, and one end of the second spring 403b is fixed to the inner wall of the fixing sleeve 401a.

[0059] When the gas inside the airbag 401c is released outward, the second spring 403b can push the force-bearing plate 403a to move, thereby driving the fixing column 401b and the connecting column 301e to move in the opposite direction through the force-bearing plate 403a.

[0060] Specifically, a third spring 403c is fixed to the inner top wall of the stabilizing sleeve 401e, and the bottom end of the third spring 403c is in contact with the sensing ball 401g.

[0061] The third spring 403c applies downward squeezing force to the sensing ball 401g. Only when the vibration generated by the new energy vehicle is large, the sensing ball 401g will offset the elastic force of the third spring 403c and move upward. When the vibration is small, the sensing ball 401g cannot move, thereby avoiding the situation where the sensing ball 401g moves too frequently.

[0062] Example 3

[0063] Reference Figure 1-Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0064] Specifically, a connecting block 302a is fixed to one side of the movable plate 301c, an extrusion rod 302b is arranged at the bottom of the connecting block 302a, a force groove 302a-1 corresponding to the extrusion rod 302b is opened on the connecting block 302a, a push column 302c is fixed to the bottom of the extrusion rod 302b, and the bottom end of the push column 302c passes through to the outside of the bottom end of the rotating column 201h.

[0065] The inner wall of the force groove 302a-1 is inclined, the extrusion rod 302b is U-shaped, and the bottom end of the rotating column 201h extends into the hexagonal groove. When the rotating wrench is inserted into the hexagonal groove, the push column 302c will be pushed to move upward, and the extrusion rod 302b will be driven to move upward through the push column 302c, so that the extrusion rod 302b squeezes the inclined surface of the inner wall of the force groove 302a-1, and the two cooperate to drive the connecting block 302a to move, and the movable plate 301c and the insertion rod 301d are driven to move through the connecting block 302a, so that the insertion rod 301d can be separated from the slot 301a-1.

[0066] Specifically, a fourth spring 302d is fixed to one side of the connecting block 302a, and one end of the fourth spring 302d is fixed to another connecting block 302a.

[0067] The fourth spring 302d applies a thrust to the two connecting blocks 302a, and the connecting blocks 302a drive the movable plate 301c and the insertion rod 301d to move, so that the insertion rod 301d is more tightly engaged with the slot 301a-1.

[0068] Specifically, a fifth spring 302e is fixed to the bottom of the extrusion rod 302b, and the bottom end of the fifth spring 302e is fixed to the inner wall of the chamber 201h-2 and is sleeved on the outside of the push column 302c.

[0069] The fifth spring 302e is used to apply a pulling force to the extrusion rod 302b so that it can return to its original position after moving.

[0070] Specifically, a stabilizing block 202a is fixed on the top of the locking block 201e, a stabilizing column 202b is fixed inside the fixing rod 201b, the stabilizing block 202a is movably connected to the outside of the stabilizing column 202b, a sixth spring 202c is sleeved on the outside of the stabilizing column 202b, and both ends of the sixth spring 202c are respectively fixed to the two stabilizing blocks 202a.

[0071] The stabilizing block 202a cooperates with the stabilizing column 202b to position the locking block 201e to prevent it from shifting during movement. When the extrusion block 201g is separated from the locking block 201e, the stabilizing block 202a can be pulled to move by the sixth spring 202c, and the locking block 201e can be driven to move into the fixing rod 201b by the stabilizing block 202a, thereby releasing the restriction on the fixing block 201a, and then the fixing block 201a can be moved downward, and the battery pack 102 can be disassembled.

[0072] In summary, the battery replacement locking structure for new energy vehicles of the present invention has the following advantages:

[0073] 1. It can provide a stable fastening force to the battery pack 102, and the fastening force will not be reduced due to frequent installation and removal;

[0074] Second, the buffering and shock-resistant effect of the battery pack 102 can be improved to prevent the battery pack 102 from being subjected to excessive vibration, which may cause damage to its internal components;

[0075] 3. When the battery pack 102 is subjected to relatively strong vibration, the tightening force of the battery pack 102 may be increased;

[0076] Fourth, when the battery pack 102 is in a stable state, the additional tightening force can be reduced to the initial position, thereby avoiding the situation where the wear of each component is aggravated.

[0077] During use, when fixing the battery pack 102, the battery pack 102 is placed in the frame chassis 101 through the mechanical trolley inside the battery swap station, and the fixing block 201a is sleeved on the outside of the fixing rod 201b. At this time, the battery pack 102 is moved upward so that the fixing block 201a contacts the buffer pad 201d, and then the rotating column 201h is rotated by rotating the wrench. At this time, the fixed shaft 201i will slide in the spiral groove 201h-1, and the two will cooperate to drive the extrusion block 201g to move downward, so that the oblique surfaces on both sides of the extrusion block 201g squeeze the two locking blocks 201e, thereby pushing the locking block 201e to move to the outside of the fixing rod 201b, and making The top inclined surface of the locking block 201e contacts the fixing block 201a and squeezes the fixing block 201a, so that the fixing block 201a can move upward and make the fixing block 201a contact with the buffer pad 201d more tightly, thereby completing the locking and fixation of the battery pack 102. The buffer pad 201d can buffer and shock the battery pack 102, thereby preventing the battery pack 102 from being subjected to strong vibrations when the new energy vehicle is bumpy. The locking block 201e squeezes and supports the fixing block 201a to lock and fix the battery pack 102, which can avoid the situation where the tightening force is reduced during frequent installation and disassembly.

[0078] When the new energy vehicle bumps and produces a strong vibration, the sensing ball 401g will move upward due to the vibration and separate from the piston plate 401f. At this time, the first spring 401h will push the piston plate 401f to move upward. When the sensing ball 401g moves downward, it will press the piston plate 401f downward again. When the piston plate 401f is downward, the gas under it will be transported to the airbag 401c through the connecting pipe 401d. After the gas is injected into the airbag 401c, it will expand and push the fixed column 401b to move, so that the fixed column 401b drives the connecting column 301e to move, so that the tooth plate 301b can be driven to move through the connecting column 301e.

[0079] When the tooth plate 301b moves, it drives the gear 301a to rotate, and drives the rotating column 201h to rotate through the gear 301a. When the rotating column 201h rotates, the extrusion block 201g can continue to squeeze the locking block 201e downward, so that the locking block 201e can continue to move outward and squeeze the fixed block 201a upward, so that the fixed block 201a can be more tightly contacted with the buffer pad 201d, thereby increasing the fastening force of the battery pack 102, thereby preventing the battery pack 102 from being displaced or the fixing force from loosening when it is vibrated.

[0080] When the new energy vehicle resumes stable driving, the piston plate 401f and the sensing ball 401g will both reset. At this time, the gas inside the airbag 401c will slowly leak outward, thereby relieving the squeezing of the fixed column 401b, so that the tooth plate 301b can be reset, and the gear 301a and the rotating column 201h can be rotated in the opposite direction to the initial angle, so that the fastening force of the battery pack 102 can be restored to the initial fixed state, thereby reducing the wear of each component and preventing the fixed block 201a from applying a strong squeezing force to the buffer pad 201d for a long time, which will cause damage to the buffer pad 201d and reduce the buffering and shock-resistant effect.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
