[0090] In one embodiment of the present application, the electric device 1 is a vehicle. As shown in Figure 1 , it is a structural schematic diagram of a vehicle according to an embodiment of the present application. The vehicle can be a fuel automobile, a gas automobile or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile or a range extended automobile, etc. The vehicle can be provided with a motor 20, a controller 30 and a battery 300 inside. The controller 30 is used to control the battery 300 to supply power to the motor 20. For example, the battery 300 can be arranged at the bottom, the front or the rear of the vehicle. The battery 300 can be used for power supply of the vehicle, for example, the battery 300 can be used as an operating power source of the vehicle, used for circuit system of the vehicle, for example, used for power demand of starting, navigation and operation of the vehicle. In another embodiment of the present application, the battery 300 can not only be used as an operating power source of the vehicle, but also be used as a driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0091] The embodiments of the present application provide an electric device 1 using a battery 300 as a power source.

[0093] As shown in Figure 2 , Figure 3As shown, the support 100 comprises a support body 110 and a second connector 140, and the battery 300 comprises a first connector 310 for outputting the electric energy of the battery 300. The second connector 140 is mounted on the support body 110 and is used to be connected with the first connector 310 of the battery 300 to deliver the electric energy of the battery 300 to the electrical equipment body. The connecting end of the second connector 140 is arranged towards the gravity direction of the battery 300, so that the first connector 310 of the battery 300 can be connected with the second connector 140 in the opposite direction of the gravity direction to realize the connection between the first connector 310 and the second connector 140. By arranging the connecting end of the second connector 140 towards the gravity direction, the first connector 310 of the battery 300 can be connected with the second connector 140 in the opposite direction of the gravity direction, so that after the first connector 310 is connected with the second connector 140, the damage of the first connector 310 and / or the second connector 140 caused by the gravity of the battery 300 will not affect the use of the battery 300 or the electrical equipment 1. Moreover, during the installation of the battery 300, the first connector 310 can be connected with the second connector 140 by only pushing the battery 300 to move in the opposite direction of the gravity, which is convenient and fast.

[0094] In some embodiments, the battery assembly 10 further comprises a first conductive piece 410 and a second conductive piece 420, and the one end of the first conductive piece 410 and the one end of the second conductive piece 420 are connected with the second connector 140.

[0095] As shown, Figure 4 The connecting end of the second connector 140 comprises a terminal 141 for electrically connecting with the battery 300, and the terminal 141 extends along the gravity direction when the second connector 140 is mounted on the fixing frame 114 of the support 100. The extending direction of the terminal 141 is consistent with the connecting direction of the first connector 310 and the second connector 140, which avoids the bending or even breaking of the terminal 141 caused by the inconsistency between the extending direction of the terminal 141 and the connecting direction during the connection between the first connector 310 and the second connector 140, so as to affect the electric conduction performance between the first connector 310 and the second connector 140 and the electric safety performance of the electrical equipment 1.

[0096] The second connector 140 further includes a base 142, a first wire 143 and a second wire 144, the connecting end of the second connector 140 is fixed to the base 142, the terminal 141 of the connecting end of the second connector 140 includes first and second terminals with opposite polarities, one end of the first wire 143 is connected to the first terminal, one end of the second wire 144 is connected to the second terminal, the first wire 143 and the second wire 144 respectively extend from the two sides of the base 142 along the first direction A, and the first direction A is perpendicular to the direction of gravity. The first wire 143 and the second wire 144 respectively extend from the two sides of the base 142 along the first direction A, so that the second connector 140 has a smaller size in the second direction B, and the space occupied by the second connector 140 in the second direction B can be reduced. It should be noted that the first direction A, the second direction B and the direction of gravity are perpendicular to each other.

[0097] In addition, the first wire 143 and the second wire 144 extend out of the base 142 in opposite directions, reducing the risk of short circuit of the first wire 143 and the second wire 144, and improving the safety performance of the electrical equipment 1.

[0098] The first and second terminals are arranged at intervals along the first direction A so that the two terminals with opposite polarities have a certain distance therebetween, reducing the risk of short circuit of the first wire 143 and the second wire 144, and improving the safety performance of the electrical equipment 1.

[0099] The first and second terminals can have other arrangements, for example, in some embodiments, the arrangement direction of the first and second terminals is arranged at an angle with the first direction A.

[0100] In some embodiments, the first wire 143 and the second wire 144 are at least partially located in the base 142, the base 142 is provided with a first wire outlet hole 145 and a second wire outlet hole 146 on the two opposite sides along the first direction A, the first wire 143 extends from the first wire outlet hole 145, and the second wire 144 extends from the second wire outlet hole 146, one end of the first wire 143 extending out of the first wire outlet hole 145 is used for electrical connection with the electrical equipment 1, and one end of the second wire 144 extending out of the second wire outlet hole 146 is used for electrical connection with the electrical equipment 1, so that the battery 300 can deliver electrical energy to the electrical equipment 1 through the second connector 140.

[0101] The arrangement of the first wire outlet hole 145 and the second wire outlet hole 146 separates and limits the first wire 143 and the second wire 144 in their respective spaces, further reducing the risk of short circuit of the first wire 143 and the second wire 144, and improving the safety performance of the electrical equipment 1. In addition, the first wire outlet hole 145 and the second wire outlet hole 146 can also function to make the first wire 143 and the second wire 144 extend in a predetermined direction.

[0102] In some embodiments, the center line of the first wire outlet hole 145 and the center line of the second wire outlet hole 146 coincide, so that the structure of the second connector 140 is symmetrical or tends to be symmetrical, which is convenient for manufacturing.

[0103] In some embodiments, the first wire outlet hole 145 and the second wire outlet hole 146 can also be arranged on the same side of the base 142 along the first direction A, and the first wire 143 and the second wire 144 both extend out of the base 142 from the same side of the base 142 after the second connector 140 and the first connector 310 are docked.

[0104] In some embodiments, the size of the base 142 along the first direction A is greater than the size of the base 142 along the second direction B, wherein the first direction A, the second direction B and the direction of gravity are perpendicular to each other.

[0105] The first wire 143 and the second wire 144 are at least partially located in the base 142, which can be understood as that the first wire 143 can be partially or entirely located in the base 142, and the second wire 144 can be partially or entirely located in the base 142. When the first wire 143 and the second wire 144 are only partially located in the base 142, the part of the first wire 143 and the second wire 144 extending out of the base 142 is convenient for electrical connection with the electrical equipment 1. When the first wire 143 and the second wire 144 are entirely located in the base 142, the wires on the electrical equipment 1 need to be extended into the base 142 to be electrically connected with the first wire 143 and the second wire 144.

[0106] The first wire 143 and the second wire 144 are at least partially located in the base 142, which can also be understood as that part or all of at least one of the first wire 143 and the second wire 144 is located in the base 142.

[0107] In some embodiments, one end of the first wire 143 extending out of the base 142 is connected with the first conductive part 410, and one end of the second wire 144 extending out of the base 142 is connected with the second conductive part 420.

[0108] In other embodiments, the first conductive part 410 and the first wire 143 can be an integral structure, and the second conductive part 420 and the second wire 144 can be an integral structure.

[0109] The second connector 140 further comprises a second guide part 147 connected to the base 142. The second guide part 147 is two, and the two second guide parts 147 are arranged on both sides of the terminal 141 of the second connector 140 along the first direction A.

[0110] In some embodiments, the base 142 has a dimension along the first direction A that is greater than a dimension along the second direction B, the first direction A, the second direction B and the direction of gravity are perpendicular to each other. The larger dimension of the base 142 along the first direction A facilitates the installation and extension path arrangement of the first and second wires 143 and 144, and facilitates the arrangement of the first terminal, the second terminal and the two second guide portions 147. Moreover, the dimension along the first direction A is greater than the dimension along the second direction B, so that the dimension of the base 142 along the second direction B is smaller, which can reduce the space occupied by the bracket 100 and the weight of the bracket 100, and avoid the bracket 100 from imposing a burden on the structural size and weight of the electrical equipment 1.

[0111] In some embodiments, the second connector 140 is floatingly mounted to the bracket body 110, such as being connected between the base 142 of the second connector 140 and the bracket body 110 by an elastic member, to achieve floating connection of the second connector 140 and the bracket body 110, and avoid the first connector 310 from failing to be accurately matched in place due to manufacturing or installation errors during the mating process with the second connector 140.

[0112] As shown in Figure 5 The first connector 310 includes a base 311 and a port 312, the port 312 is arranged at the connection end of the first connector 310, the base 311 has a first surface 3111, one end of the connection end of the first connector 310 is connected to the first surface 3111 of the base 311, and a sealing groove 3112 is arranged on the first surface 3111. The profile of the sealing groove 3112 matches the profile of the base 311, and a sealing member is arranged in the sealing groove 3112.

[0113] The connection end of the first connector 310 includes the port 312, the port 312 is provided with positive and negative terminals, and the port 312 extends out of the first opening 3211, so that the positive and negative terminals of the first connector 310 can be respectively mated with the terminals 141 of the second connector 140.

[0114] The first connector 310 is further provided with a first guide portion 313, the first guide portion 313 is connected to the base 311 of the first connector 310, and the first guide portion 313 is used to guide the second connector 140 during mating of the first connector 310, so as to align the position of the second connector 140 with the first connector 310. The arrangement of the first guide portion 313 can ensure accurate mating of the first connector 310 and the second connector 140.

[0115] To further ensure the accuracy of the docking, the first guide portion 313 is configured to cooperate with the second guide portion 147 to guide the second connector 140 to align with the first connector 310 when the first connector 310 and the second connector 140 are docked, because the second connector 140 is provided with the second guide portion 147. The first connector 310 and the second connector 140 can be docked in a guided manner through the cooperation of the first guide portion 313 and the second guide portion 147, thereby improving the accuracy of the docking of the first connector 310 and the second connector 140.

[0116] In some embodiments, the first guide portion 313 is a guide sleeve, and the second guide portion 147 is a guide post. The first connector 310 and the second connector 140 can be docked in a guided manner through the cooperation of the guide sleeve and the guide post, which is simple in implementation and high in reliability. The first guide portion 313 is two, and the two first guide portions 313 are respectively located on the two sides of the port 312 of the first connector 310 along the first direction A. The second guide portion 147 is also two, and the second guide portion 147 is arranged in one-to-one correspondence with the first guide portion 313.

[0117] In some embodiments, the first guide portion 313 can also be a guide post, and the second guide portion 147 can be a guide sleeve.

[0118] As shown in Figure 6 , Figure 7 The battery assembly 10 also includes a first sealing member 500, which is used to seal the connection between the first guide portion 313 and the second guide portion 147 when the first guide portion 313 and the second guide portion 147 are cooperated into position. In some embodiments, the first sealing member 500 is arranged on the side of the base 142 of the second connector 140 opposite to the first connector 310. The first sealing member 500 is used to seal the space between the end face of the guide sleeve and the base 142 of the second connector 140 after the first connector 310 and the second connector 140 are docked, so as to avoid impurities such as dust and moisture from entering the space between the guide sleeve and the guide post, thereby damaging the guide sleeve and the guide post and affecting the positioning and guiding performance of the guide post and the guide sleeve. The first sealing member 500 can be made of butyronitrile rubber, fluorine rubber, nylon, or the like.

[0119] Cooperating into position is the cooperation state of the first guide portion 313 and the second guide portion 147 after the first connector 310 and the second connector 140 are docked.

[0120] In some embodiments, the first sealing member 500 can also be arranged on the end face of the guide sleeve of the first connector 310.

[0121] In some embodiments, the first guide part 313 is a guide post, the second guide part 147 is a guide sleeve, and the first seal 500 is used to seal between the end surface of the second guide part 147 and the base 142 of the first connector 310. The first seal 500 can be arranged on the end surface of the guide sleeve of the second connector 140 or on the side of the base 311 of the first connector 310 opposite to the second connector 140.

[0122] When the guide sleeve and the guide post are matched in place, the connection end of the connector in which the guide sleeve is arranged is sleeved with the connection end of the connector in which the guide post is arranged, and the end surface of the connection end of the connector in which the guide sleeve is arranged is sealed from the connector in which the guide post is arranged by the first seal 500. In some embodiments, the connection end of the first connector 310 is sleeved with the connection end of the second connector 140, and the connection end of the first connector 310 abuts against the first seal 500 to achieve sealing between the connection end of the first connector 310 and the connection end of the second connector 140.

[0123] The sealing connection between the connection end of the first connector 310 and the connection end of the second connector 140 can prevent fluids or solid particles from entering between the first connector 310 and the second connector 140 from the joint gap between the first connector 310 and the second connector 140, and prevent external impurities such as dust and moisture from entering between the first connector 310 and the second connector 140 to affect the electrical connection performance and safety performance of the two. The sealing connection of the first guide part 313 and the second guide part 147 and the connection end of the first connector 310 and the connection end of the second connector 140 share one sealing structure, which not only reduces the number of sealing structures of the battery assembly 10, but also makes the sealing connection of the battery assembly 10 continuous, further ensuring the sealing effect.

[0124] In some embodiments, the first guide part 313 and the second guide part 147 can also be other guide matching modes, for example, the first guide part 313 is a guide post, and the second guide part 147 is a sliding groove matched with the guide post, or the first guide part 313 is a sliding groove, and the second guide part 147 is a guide post matched with the sliding groove.

[0125] In order to improve the sealing performance of the first connector 310 to the first opening 3211, the battery 300 further comprises a seal (not shown in the figure), which is arranged between the first surface 3111 and the inner surface of the box 320 and surrounds the first opening 3211, and is used to achieve sealing connection between the first connector 310 and the box 320.

[0126] The use environment of the battery 300 is not a dust-free environment, but often accompanied by a large amount of dust, rainwater and other impurities in the environment.

[0127] In some embodiments, the battery assembly 10 further comprises a second seal 700, which seals between the connecting end of the first connector 310 and the connecting end of the second connector 140 when the first connector 310 and the second connector 140 are mated into place. When the first connector 310 and the second connector 140 are mated, the connecting end of the first connector 310 is sleeved on the connecting end of the second connector 140, and the second seal 700 is arranged between the inner circumferential surface of the connecting end of the first connector 310 and the outer circumferential surface of the connecting end of the second connector 140. The second seal 700 can be arranged on the inner circumferential surface of the connecting end of the first connector 310, or on the outer circumferential surface of the connecting end of the second connector 140.

[0128] The second seal 700 can be made of materials such as butyronitrile rubber, fluororubber, nylon, etc. The arrangement of the second seal 700 can prevent fluids or solid particles from entering between the first connector 310 and the second connector 140 from the mating gap between the first connector 310 and the second connector 140, and prevent external impurities such as dust and moisture from entering between the first connector 310 and the second connector 140 to affect the electrical connection performance and safety performance of the two. In addition, the arrangement of the second seal 700 can also play a buffering role at the mating position of the first connector 310 and the second connector 140, avoiding the impact of vibration, impact, etc. of the electrical equipment 1 on the first connector 310 and the second connector 140 at the mating position, thereby affecting the service life of the first connector 310 and the second connector 140.

[0129] In some embodiments, when the first connector 310 and the second connector 140 are mated, the connecting end of the second connector 140 is sleeved on the connecting end of the first connector 310, and the second seal 700 is arranged between the inner circumferential surface of the connecting end of the second connector 140 and the outer circumferential surface of the first connector 310. The second seal 700 can be arranged on the inner circumferential surface of the connecting end of the second connector 140, or on the outer circumferential surface of the connecting end of the first connector 310.

[0130] The second seal 700 is arranged between the inner circumferential surface of the connecting end of the first connector 310 and the outer circumferential surface of the connecting end of the second connector 140, or the second seal 700 is arranged between the inner circumferential surface of the connecting end of the second connector 140 and the outer circumferential surface of the connecting end of the first connector 310. The second seal 700 can provide radial resistance to the inner circumferential surface and the outer circumferential surface in contact therewith, thereby ensuring the sealing performance and making the mating of the first connector 310 and the second connector 140 more firm and reliable.

[0131] Dust, moisture and other impurities in the environment also have a great influence on the conductivity and safety performance of the first and second conductive wires 143 and 144. In some embodiments, the second connector 140 further comprises a sealing ring 148, which is arranged in the base 142, and the sealing ring 148 is used to realize the sealing between the first conductive wire 143 and the base 142, and the sealing between the second conductive wire 144 and the base 142. The arrangement of the sealing ring 148 can prevent dust, moisture and other impurities from entering between the first conductive wire 143 and the base 142 and between the second conductive wire 144 and the base 142, thereby ensuring the conductivity of the first and second conductive wires 143 and 144 and improving the safety performance of electricity use.

[0132] As shown in Figure 8 , Figure 9 In some embodiments, the battery 300 further comprises a box 320 and a battery cell 330, the battery cell 330 is arranged in the box 320, and the first connector 310 is electrically connected with the battery cell 330 to output the electric energy of the battery 300. The first connector 310 is used to be connected with the second connector 140 to realize the delivery of the electric energy of the battery 300 to the electrical equipment 1.

[0133] As shown in Figure 9 , Figure 10 In some embodiments, the outer surface of the box 320 is formed with a groove 321 recessed towards the inside of the box 320, and the first connector 310 is arranged in the groove 321. Only the top opening of the groove 321 needs to be aligned with the terminal 141 of the second connector 140 in the direction of gravity, and the battery 300 is moved in the opposite direction of the direction of gravity to realize the quick connection of the battery 300 and the second connector 140. When the second connector 140 is connected with the first connector 310, the second connector 140 is at least partially located in the groove 321.

[0134] The groove 321 is used to arrange the first connector 310, which avoids the excessive occupation of the space inside the box 320 by the first connector 310. The arrangement of the groove 321 also provides a connection space for the connection of the first connector 310 and the second connector 140. When it is needed to output the electric energy of the battery cell 330, the second connector 140 on the electrical equipment 1 is connected with the first connector 310 at the position of the groove 321, and the second connector 140 is partially or entirely located in the groove 321, which can reduce the distance between the battery 300 and the electrical equipment 1, make the distance between the battery 300 and the electrical equipment 1 closer, and also reduce the installation space required for the installation of the battery 300 on the electrical equipment 1, so that the structure of the electrical equipment 1 installed with the battery 300 is more compact.

[0135] In some embodiments, the terminal 141 of the second connector 140 is arranged towards the battery 300 in the direction of gravity, so that the first connector 310 can be docked with the second connector 140 in the opposite direction of gravity. When the second connector 140 is docked with the first connector 310, the second connector 140 is partially or entirely located in the recess 321, which can reduce the size of the electric device 1 for mounting the battery 300 in the direction of gravity, and the first connector 310 is docked with the second connector 140 in the opposite direction of gravity, which can make full use of the space of the electric device 1 in the direction of gravity, and can reduce the lateral size of the electric device 1.

[0136] Please continue to see Figure 9 、 Figure 10 In some embodiments, the box 320 comprises a lower shell 322 and an upper cover 323, the battery cell 330 is arranged in the lower shell 322, and the upper cover 323 covers the lower shell 322. The recess 321 is formed on the outer surface of the upper cover 323 and is recessed downward, and the recess 321 penetrates through one side of the upper cover 323 in the width direction. The box 320 adopts a split structure, which is convenient for mounting the battery cell 330 and other components inside the box 320, and is also convenient for manufacturing the box 320.

[0137] In some embodiments, the first connector 310 is arranged on the bottom wall of the recess 321, so that the first connector 310 is located at the deepest position of the recess 321, and when the second connector 140 is docked with the first connector 310, it can be located in the recess 321 as much as possible, further reducing the distance between the battery 300 and the electric device 1, so that the structure of the mounted battery 300 and the electric device 1 is more compact.

[0138] In other embodiments, the first connector 310 can also be arranged on the side wall of the recess 321.

[0139] Since the size of the base 142 of the second connector 140 in the first direction A is greater than that in the second direction B, correspondingly, the size of the recess 321 in the first direction A is greater than that in the second direction B, which can reduce the occupation of the space in the box 320 in the second direction B by the recess 321, and will not affect the placement of the battery cell 330.

[0140] The bottom wall of the groove 321 is provided with a first opening 3211, and the first connector 310 passes through the first opening 3211 to output the electric energy of the battery monomer 330 to the outside of the box body 320 through the first connector 310. The first connector 310 passes through the first opening 3211 to be connected with the second connector 140 and the battery monomer 330 inside the box body 320 at the same time, and the first connector 310 has two parts located in the groove 321 and accommodated in the box body 320 by the first opening 3211, which reduces the space occupation of the first connector 310 to the groove 321, leaves more space for the second connector 140 to be connected with the first connector 310, so that the second connector 140 can be located in the groove 321 as much as possible, and further makes the structure of the installed battery 300 and the electric device 1 more compact.

[0141] The first connector 310 passes through the first opening 3211 from the inside of the box body 320, and the first connector 310 covers the first opening 3211 and is sealingly connected with the box body 320 to close the first opening 3211. The first connector 310 covers and seals the first opening 3211, which can avoid rainwater, dust in the air and the like from entering the box body 320 from the first opening 3211 to damage the components inside the box body 320.

[0142] The base body 311 of the first connector 310 covers the first opening 3211 from the inside of the box body 320, the first surface 3111 of the base body 311 faces the first opening 3211, and the port 312 passes out of the first opening 3211. The base body 311 covers the first opening 3211 from the inside of the box body 320 to seal the first opening 3211, and when the second connector 140 is connected with the first connector 310, the base body 311 can prevent the first connector 310 from moving in the direction close to the second connector 140, so as to avoid that the second connector 140 pulls the first connector 310 to disconnect the electrical connection between the first connector 310 and the battery monomer 330.

[0143] In some embodiments, the sealing groove 3112 is arranged around the first opening 3211 on the base body 311 of the first connector 310. When the first connector 310 passes through the first opening 3211, the sealing member abuts against the lower surface of the upper cover body 323 from bottom to top to realize the sealing between the first connector 310 and the box body 320. The sealing member is arranged in the box body 320, which can avoid the sealing failure caused by external abrasion, corrosion and the like, and in addition, the sealing member is arranged in the box body 320 to avoid occupying the space of the groove 321, so that the groove 321 can leave more space for the second connector 140 to be connected with the first connector 310. The sealing member is arranged around the first opening 3211, and the sealing performance is better.

[0144] In some embodiments, a sealing groove 3112 can also be formed on the inner surface of the upper cover body 323, and a sealing member is arranged in the sealing groove 3112 of the upper cover body 323. When the first connector 310 passes through the first opening 3211, the first connector 310 abuts against the sealing member from bottom to top to achieve the sealing between the first connector 310 and the box body 320. The material of the sealing member can be selected from nitrile rubber, silicone rubber, nylon, etc.

[0145] In some embodiments, the first connector 310 and the box body 320 can also be sealed and connected by other ways.

[0146] The outer surface of the upper cover body 323 of the box body 320 is further provided with a guide groove 324 recessed to the inside of the box body 320. The guide groove 324 is in communication with the groove 321, and the guide groove 324 extends along the width direction of the upper cover body 323 and penetrates through the side of the upper cover body 323 away from the groove 321 in the width direction. The height position of the bottom wall of the groove 321 is lower than that of the guide groove 324, which facilitates the placement of the conductive wire connected between the second connector 140 and the electrical equipment 1. The fixing frame 114 of the bracket body 110 can also be partially accommodated in the guide groove 324, which not only reduces the size of the battery assembly 10 in the direction of gravity, but also limits the conductive wire placed in the guide groove 324.

[0147] It should be noted that the first direction A, the extension direction of the groove 321 and the extension direction of the guide groove 324 are consistent.

[0148] In order to ensure that the first connector 310 and the box body 320 have a stable and reliable connection relationship, in some embodiments, the battery 300 further comprises a fixing member 350 configured to pass through the first through hole 3212 on the bottom wall of the groove 321 to be connected with the first connector 310. The threaded connecting member can be a bolt, a screw, etc. The first connector 310 is fixed to the box body 320 by the fixing member 350, so that the first connector 310 cannot move relative to the box body 320, thereby enabling the first connector 310 and the battery monomer 330, and the first connector 310 and the second connector 140 to maintain a stable connection relationship.

[0149] In some embodiments, as Figure 11As shown, the battery 300 further comprises a reinforcing plate 340 arranged on the bottom wall of the groove 321, the reinforcing plate 340 is provided with a second through hole 341 and a second opening 342 through which the first connector 310 passes, the first opening 3211 is aligned with the second opening 342, and the port 312 and the first guide part 313 of the first connector 310 pass through the first opening 3211 and the second opening 342 in sequence. The second through hole 341 is aligned with the first through hole 3212, and the fixing member 350 passes through the second through hole 341 and the first through hole 3212 in sequence to connect with the first connector 310, so as to fix the reinforcing plate 340 and the first connector 310 to the box body 320. The reinforcing plate 340 can increase the stress area and ensure the overall sealing.

[0150] The arrangement of the reinforcing plate 340 can further improve the connection stability between the first connector 310 and the box body 320, and the reinforcing plate 340 can withstand the impact when the second connector 140 on the electrical equipment 1 is docked with the first connector 310. In addition, the bottom wall of the groove 321 is provided with the first opening 3211, so that the strength of the bottom wall of the groove 321 is reduced, thereby reducing the carrying capacity of the bottom wall of the groove 321, and the arrangement of the reinforcing plate 340 can make up for the defect of reduced carrying capacity caused by the first opening 3211 arranged on the bottom wall of the groove 321.

[0151] In some embodiments, the first through hole 3212 is a plurality of first through holes 3212, each first through hole 3212 is arranged along the edge of the first opening 3211, the reinforcing plate 340 is provided with a plurality of second through holes 341, the second through hole 341 is arranged one by one corresponding to the first through hole 3212, and the first through hole 3212 is arranged one by one corresponding to the mounting hole on the first connector 310. Each second through hole 341 is provided with a fixing member 350 in the first through hole 3212 and the mounting hole on the first connector 310 corresponding thereto, so that the first connector 310, the box body 320 and the reinforcing plate 340 are connected at multiple positions, ensuring uniform and stable connection, improving the anti-shock and impact resistance. In addition, the fixing member 350 simultaneously fixes the reinforcing plate 340 and the first connector 310 to the box body 320, which can reduce the number of fixing members 350, reduce the weight of the battery 300, save costs, and reduce the assembly difficulty of the battery 300.

[0152] The battery 300 further comprises a locking part 360 (see Figure 7 , Figure 8 The locking part 360 is mounted on the outer side of the box body 320.

[0153] As shown in Figure 12 , the bracket body 110 comprises a first beam 111, a second beam 112 and a fixing frame 114, the first beam 111 and the second beam 112 are arranged oppositely, and a containing space 115 for containing the battery 300 is formed between the first beam 111 and the second beam 112.

[0154] The bracket 100 also includes a third beam 113, which connects the first beam 111 and the second beam 112. The number of third beams 113 can be one, two, or more. In some embodiments, there are two third beams 113, which are arranged opposite each other. The provision of third beams 113 improves the structural stability of the bracket body 110, facilitating stable installation of the battery 300.

[0155] In some embodiments, there are two first beams 111 and one second beam 112. The two first beams 111 are positioned opposite each other and connected to a third beam 113. The second beam 112 is positioned between the two first beams 111 to form two receiving spaces 115. Each receiving space 115 is provided with a second connector 140. The two ends of the second beam 112 are connected to the two third beams 113, respectively. The second beam 112, the two first beams 111, and the two third beams 113 collectively form two "mouth"-shaped receiving spaces 115. The two receiving spaces 115 share the same second beam 112.

[0156] The bracket body 110 forms two accommodating spaces 115 through the second beam 112, which can accommodate two batteries 300. The two batteries 300 can provide a large amount of electrical energy for the electrical device 1 to ensure the normal operation of the electrical device 1, or one of the two batteries 300 can be used as a backup power supply, so that the electrical device 1 can continue to work stably for a long time.

[0157] In some embodiments, a fixing bracket 114 is provided corresponding to each receiving space 115, and a second connector 140 is mounted on the fixing bracket 114. The connection end of the second connector 140 is arranged toward the battery 300 in the direction of gravity, so that the battery 300 can be connected to the second connector 140 in the direction opposite to the direction of gravity to achieve electrical connection between the battery 300 and the second connector 140. A second connector 140 is provided on each fixing bracket 114, so that the battery 300 in each receiving space 115 has a second connector 140 that is connected thereto.

[0158] In some embodiments, the accommodating space 115 may be divided into multiple subspaces, each subspace may accommodate a battery 300 , and accordingly, a number of second connectors 140 corresponding to the number of subspaces may be provided on the fixing frame 114 corresponding to the accommodating space 115 .

[0159] The mounting brackets 114 are U-shaped and extend across the corresponding receiving spaces 115, creating an entrance for the battery 300 below the receiving spaces 115. This facilitates the mating of the first connector 310 with the second connector 140 in the direction opposite to gravity. One end of each mounting bracket 114 is connected to the first beam 111, and the other ends of each mounting bracket 114 are connected to each other.

[0160] The U-shaped fixing frame 114 can ensure that the space defined by the fixing frame 114, the first beam 111 and the second beam 112 has sufficient space in the direction of gravity, matching the thickness of the battery 300, so that after the battery 300 is installed on the bracket body 110, it can be completely accommodated in the space defined by the fixing frame 114, the first beam 111 and the second beam 112, so that the battery 300 can be stably installed on the bracket body 110.

[0161] In order to ensure the structural stability of the bracket body 110 and the load-bearing capacity of the bracket body 110 , one end of each fixing bracket 114 away from the first beam 111 may also be connected to the second beam 112 .

[0162] like Figure 13 As shown, in some embodiments, the two accommodating spaces 115 share a fixing frame 114 . The fixing frame 114 is U-shaped, and two ends of the fixing frame 114 are respectively connected to the two first beams 111 .

[0163] like Figure 14 As shown, in some embodiments, there is one accommodation space 115, namely, one first beam 111, one second beam 112, and two third beams 113 together define a "mouth"-shaped accommodation space 115, and the ends of the U-shaped fixing frame 114 are respectively connected to the first beam 111 and the second beam 112. In some embodiments, the bracket body 110 may also include only the first beam 111, the second beam 112, and the fixing frame 114, and the accommodation space 115 is defined by the first beam 111 and the second beam 112.

[0164] In some embodiments, three or more receiving spaces 115 may be formed on the bracket body 110 .

[0165] The bracket 100 also includes a locking mechanism 130 mounted on the bracket body 110 for locking the battery 300 to the bracket body 110. The locking mechanism 130 ensures that the battery 300 remains stably mounted on the bracket body 110, providing stable power to the electrical device 1 even when the electrical device 1 is subject to vibration or impact during operation.

[0166] The bracket body 110 is provided with a channel 116 extending along the direction of gravity, the channel 116 extends to the lower surface of the bracket body 110 to enable the locking part 360 to enter and exit the channel 116; the locking mechanism 130 is configured to lock the locking part 360 when the locking part 360 moves upward to a predetermined position of the channel 116; and the locking mechanism 130 is configured to release the locking of the locking part 360 to enable the locking part 360 to move downward under the gravity of the battery 300 to disengage from the channel 116.

[0167] One object of the present application is to enable quick replacement of the battery 300 and the bracket 100. The present application enables the first connector 310 of the battery 300 and the second connector 140 of the bracket 100 to be quickly connected in the opposite direction of the direction of gravity by arranging the connecting end of the second connector 140 on the bracket 100 to face the battery 300 in the direction of gravity. In order to maintain the stable connection of the battery 300 and the bracket 100, the battery 300 can be locked on the bracket 100 by arranging the locking mechanism. However, the structure of the locking mechanism 130 of the bracket 100 in the related art is complex, and the process of locking and unlocking the battery 300 is complex, which is not conducive to the quick replacement of the battery 300.

[0168] In view of this, as shown in Figure 15 The bracket body 110 is provided with a channel 116 extending along the direction of gravity, the channel 116 extends to the lower surface of the bracket body 110 to enable the locking part 360 to enter and exit the channel 116. Among them, the locking mechanism 130 is configured to lock the locking part 360 when the locking part 360 moves upward to a predetermined position of the channel 116; and the locking mechanism 130 is configured to release the locking of the locking part 360 to enable the locking part 360 to move downward under the gravity of the battery 300 to disengage from the channel 116.

[0169] The first beam 111 and the second beam 112 are each provided with a channel 116, the channel 116 on the first beam 111 extends to the lower surface of the first beam 111, and the channel 116 on the second beam 112 extends to the lower surface of the second beam 112.

[0170] Based on the above scheme, during the locking or unlocking of the battery 300, the battery 300 only needs to move upward or downward in the channel 116, without needing to adjust the battery 300 in other directions (such as the front-rear direction of the vehicle). Especially when unlocking the battery 300, after the locking mechanism 130 releases the locking of the locking portion 360, the locking portion 360 of the battery 300 can be separated from the channel 116 under the action of gravity of the battery 300, so that the locking and unlocking of the battery 300 are both convenient and fast, which is beneficial to improve the efficiency of the installation and dismounting of the battery 300 and to realize the quick replacement of the battery 300. In addition, for the support body 110, only the channel 116 needs to be provided to cooperate with the locking portion 360, without the need for excessive design, so as to be beneficial to simplify the structure of the support body 110.

[0171] The "predetermined position" of the channel 116 can be any appropriate position in the channel 116. For example, in the embodiment as shown in FIG. 1, the upper end of the channel 116 is closed, and the "predetermined position" can be the upper end of the channel 116. In other embodiments (not shown) in which the channel 116 is closed or open, a limiting protrusion can be provided on the side wall of the channel 116, and the "predetermined position" can be the position defined by the bottom surface of the limiting protrusion. Figure 3 The locking mechanism 130 can be any appropriate structure. For example,

[0172] Figure 16 In an embodiment of the present application, the locking mechanism 130 can include a first locking member 131, a second locking member 132, and a mounting seat 133, the first locking member 131 is rotatably mounted on the mounting seat 133, the mounting seat 133 is connected with the support body 110, and the mounting seat 133 is provided with an opening 1331 corresponding to the slide. The second locking member 132 is configured to prevent the first locking member 131 from rotating when the first locking member 131 is rotated to a locking position, so that the first locking member 131 is kept in the locking position. The first locking member 131 is configured to prevent the locking portion 360 located at the predetermined position of the channel 116 from moving downward when the first locking member 131 is in the locking position. Figure 17 As shown in FIG. 1, the locking portion 360 of the battery 300 can include a locking pin 361, one end of the locking pin 361 is connected to the box body 320, and the other end is used to cooperate with the slide.

[0173] Figure 18 As shown in FIG. 2, the locking portion 360 can further include a flange 362, the flange 362 is mounted on the box body 320 through a locking screw 363, the locking pin 361 has a threaded section, and one end of the locking pin 361 sequentially passes through the flange 362 and the side wall of the support body 110 and is locked on the support body 110 through a locking nut 364.

[0174] As shown in FIG. 2, the locking portion 360 can further include a flange 362, the flange 362 is mounted on the box body 320 through a locking screw 363, the locking pin 361 has a threaded section, and one end of the locking pin 361 sequentially passes through the flange 362 and the side wall of the support body 110 and is locked on the support body 110 through a locking nut 364. Figure 19

[0175] ​​​Thus, when the locking portion 360 of the battery 300 moves to the predetermined position of the channel 116, the locking portion 360 can be locked in the channel 116 by cooperation of the first locking member 131 and the second locking member 132, so as to realize locking of the battery 300. When unlocking is needed, the second locking member 132 can be first released from limiting the first locking member 131, so as to rotate the first locking member 131 from the locking position to the unlocking position, and realize unlocking of the battery 300.

[0176] In another embodiment of the present application, the mounting seat 133 can not be arranged, and the first locking member 131 and the second locking member 132 are directly arranged on the bracket body 110.

[0177] The extension direction of the channel 116 is consistent with the direction of gravity, and the locking mechanism 130 can lock the battery 300 on the bracket body 110 during the process of abutting the first connector 310 with the second connector 140 in the opposite direction of the direction of gravity, without the need for other operations to realize locking, so that the installation and locking mode and process of the battery 300 are simple. Moreover, after the locking mechanism 130 unlocks the battery 300, the battery 300 is separated from the channel 116 under the action of its own gravity, without the need for other steps of replacing the battery 300, and the efficiency of replacing the battery 300 is further improved.

[0178] The first locking member 131 and the second locking member 132 can be any appropriate structure, as long as they can smoothly realize locking and unlocking of the locking portion 360 of the battery 300.

[0179] As shown in Figure 20 In an embodiment of the present application, the first locking member 131 can be a ratchet wheel, and the second locking member 132 can be a pawl. The ratchet wheel is configured to be driven by the locking portion 360 to rotate in a first rotation direction (e.g., the clockwise direction of the figure plane) during upward movement of the locking portion 360. Figure 19 The pawl is configured to engage with the ratchet wheel to prevent the ratchet wheel from rotating in a second rotation direction (e.g., the counterclockwise direction of the figure plane) opposite to the first rotation direction when the locking portion 360 moves upward to the predetermined position of the channel 116, so as to lock the locking portion 360 in the channel 116 by the ratchet wheel, and realize locking of the battery 300. Figure 19

[0180] In some embodiments, cooperation of the ratchet wheel and the pawl can ensure the reliability of locking the locking portion 360, and ensure the reliability of mounting the battery 300 on the bracket 100. Moreover, when the battery 300 needs to be unlocked, the pawl can be separated from the ratchet wheel, which is convenient and fast to operate.
