DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] like Figure 1-4 The illustrated battery cover structure with replaceable terminals includes a cover 2 and a terminal. The terminal is located on the cover 2. The cover 2 is used to be connected to the battery body 1. The terminal and the cover 2 are detachably connected.

[0024] The battery referred to in this embodiment can be a lead-acid battery, a lithium hybrid battery, or other types of batteries. The cover 2 is connected to the battery body 1. Specifically, the cover 2 is covered on the battery body 1. The cover 2 is provided with a terminal, which is used to connect with a car or a motorcycle to achieve a conductive connection between the battery and the circuit system of the car or motorcycle. As a preferred implementation in this embodiment, the terminal is connected to the cover 2 in a detachable manner, so that the replacement of the terminal is convenient and quick, so that the structure can be adapted to various models of cars and motorcycles, which is conducive to improving the applicability of the battery.

[0025] Specifically, there are two terminals, which are respectively located at the two ends of the cover body 2. The terminal and the cover body 2 are snap-connected. A connecting groove 3 is provided on the cover body 2, and a connecting plug 4 is provided on the terminal. The connecting plug 4 is snap-connected with the connecting groove 3, making disassembly and assembly convenient.

[0026] It should be emphasized that the present structure further includes a lead plate 5 and a mounting plate 6. The lead plate 5 is located between the terminal and the cover body 2. A mounting groove 7 is provided on the cover body 2. One end of the lead plate 5 is bent to form a first conductive block 18. The first conductive block 18 is inserted into the mounting groove 7 so that the first conductive block 18 is electrically connected to the lithium battery in the battery body 1. A second conductive block 19 is provided on one side of the lead plate 5. The second conductive block 19 is gap-fitted with the cover body 2. Specifically, an L-shaped fitting portion is formed on the second conductive block 19. The L-shaped fitting portion is provided with a hole for the lead column led out of the lead-acid battery to pass through. The lead column passes through the hole so that the second conductive block 19 is electrically connected to the lead-acid battery in the battery body 1, that is, the lead plate 5 is electrically connected to the battery body 1. The terminal is locked on the lead plate 5 by a connecting screw 8. The mounting plate 6 is located between the lead plate 5 and the cover body 2. A nut through hole 9 is provided on the mounting plate 6. A fixing through hole 11 is provided on the lead plate 5. A connecting through hole 10 is provided on the terminal. The connecting screw 8 passes through the connecting through hole 10, the fixing through hole 11 and the nut through hole 9 in sequence. The connecting screw 8 is connected to the nut through hole 9 by a thread, so that the terminal can be replaced conveniently and quickly.

[0027] It is worth mentioning that the nut through hole 9 is an elliptical hole. Specifically, a nut is provided on the nut through hole 9, and the nut is threadedly connected to the connecting screw 8. Setting the nut through hole 9 to an elliptical shape helps to avoid eccentricity of the nut and make it adapt to the tolerance.

[0028] It should be noted that the terminal includes a first terminal 12 and a second terminal 13, the first terminal 12 and the second terminal 13 can be a positive terminal and a negative terminal respectively, the first terminal 12 and the second terminal 13 are separated and both are located on the lead plate 5, the connecting through hole 10 is located on one end of the first terminal 12 and the second terminal 13, the first terminal 12 and the second terminal 13 are respectively locked on the lead plate 5 by connecting screws 8, the connecting plug 4 is located on the other end of the first terminal 12 and the second terminal 13, and the first terminal 12 and the second terminal 13 are respectively engaged with the cover body 2. In this embodiment, the first terminal 12 and the second terminal 13 are arranged at a distance, specifically, there is a certain gap between the first terminal 12 and the second terminal 13, and the first terminal 12, the second terminal 13 and the cover body 2 are connected in a detachable manner, and the gap between the first terminal 12 and the second terminal 13 can be adjusted to ensure that the side walls of the first terminal 12 and the second terminal 13 do not protrude from the outer wall of the battery, which helps to make the first terminal 12 and the second terminal 13 compatible with batteries of different sizes.

[0029] More specifically, at least two connection through holes 10 are provided on the first terminal 12, at least two connection through holes 10 are provided on the second terminal 13, and the number of the connection screws 8 matches the number of the connection through holes 10. If only one connection through hole 10 is provided on each of the first terminal 12 and the second terminal 13, the number of the connection screws 8 matches it, that is, the first terminal 12 is locked on the lead plate 5 by one connection screw 8, and the second terminal 13 is locked on the lead plate 5 by one connection screw 8, so that the first terminal 12 and the second terminal 13 are easy to rotate around the connection screw 8 on the lead plate 5, so that the bonding strength between the first terminal 12 and the second terminal 13 and the lead plate 5 is low, and the conductivity is low, resulting in an increase in current and easy heat generation. Therefore, in this embodiment, at least two connecting through holes 10 are provided on the first terminal 12, and at least two connecting through holes 10 are provided on the second terminal 13, so that the first terminal 12 is locked on the lead plate 5 by at least two connecting screws 8, and the second terminal 13 is locked on the lead plate 5 by at least two connecting screws 8, so that the connection structure between the first terminal 12, the second terminal 13 and the lead plate 5 is relatively firm and not easy to rotate, so that the conductivity of the first terminal 12 and the second terminal 13 is relatively high, and the phenomenon of heating caused by excessive current can be avoided. It can be understood that the number of the fixing through holes 11, the nut through holes 9 and the connecting through holes 10 matches, that is, the number of the fixing through holes 11 and the nut through holes 9 is at least four. In this embodiment, at least four nut through holes 9 are provided on the mounting plate 6, so that two adjacent nut through holes 9 cannot be connected, thereby avoiding the phenomenon of heating caused by the increase of current due to the connection between the two nut through holes 9, which is beneficial to increase the strength of the mounting plate 6 structure.

[0030] Preferably, the first terminal 12 is further provided with a first wiring port 14 and a second wiring port 15, and the plane where the first wiring port 14 is located intersects with the plane where the second wiring port 15 is located. Preferably, the plane where the first wiring port 14 is located is perpendicular to the plane where the second wiring port 15 is located, and the axis of the first wiring port 14 and the axis of the second wiring port 15 are located on the same plane.

[0031] A more preferred embodiment is that a third wiring port 16 and a fourth wiring port 17 are further provided on the second terminal 13, and the plane where the third wiring port 16 is located intersects with the plane where the fourth wiring port 17 is located. Preferably, the plane where the third wiring port 16 is located is perpendicular to the plane where the fourth wiring port 17 is located, and the third wiring port 16 and the fourth wiring port 17 are staggered so that the axis of the third wiring port 16 and the axis of the fourth wiring port 17 are located on different planes.

[0032] Thus, the first terminal 12 is provided with the first connection port 14 and the second connection port 15 by the above method, and the first connection port 14 and the second connection port 15 are used to cooperate with the connection card of the car or motorcycle so that the first terminal 12 is electrically connected to the car or motorcycle. The third connection port 16 and the fourth connection port 17 are provided on the second terminal 13 by the above method, and the third connection port 16 and the fourth connection port 17 are used to cooperate with the connection card of the car or motorcycle so that the second terminal 13 is electrically connected to the car or motorcycle. The structure of the first terminal 12 and the second terminal 13 is made more flexible, so that the first terminal 12 and the second terminal 13 are more convenient to connect, that is, the connection with the car or motorcycle is more convenient, and the applicability is improved. More specifically, in this embodiment, the first terminal 12 and the second terminal 13 can be made of 2.5 mm copper plate to ensure that the connecting through hole 10, the first connection port 14, the second connection port 15, the third connection port 16, and the fourth connection port 17 have enough axial distance, which is convenient for installation and helps to improve the conductive performance.

[0033] More specifically, the two terminals include two first terminals 12 and two second terminals 13. The shape of the cover body 2 is set to be a rectangle. The two first terminals 12 and the two second terminals 13 are respectively located at the four top corners of the surface of the cover body 2. The number of connecting grooves 3 is four, and the four connecting grooves 3 are located at the four top corners of the surface of the cover body 2.

[0034] In addition, two first terminals 12 are disposed on two adjacent vertex corners on the surface of the cover body 2 , and two second terminals 13 are disposed on two adjacent vertex corners on the surface of the cover body 2 .

[0035] In summary, the present structure is convenient and quick by providing two first terminals 12 and two second terminals 13 and utilizing multi-terminal wiring. It can be adapted to high-end vehicle models with more electrical appliances, has high applicability, and meets the requirements of conductivity and strength.
