[0053] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0054] Embodiment 1

[0055] like Figure 1-Figure 5 As shown, in this embodiment, a battery terminal head is provided, including a column 1 and a connector 2; a boss 11 is arranged on the battery body, and the column 1 is arranged on the boss 11 of the battery body. The number of the columns 1 is two, and the two columns 1 are respectively the positive and negative electrodes of the battery body. The outer contour of the boss 11 is adapted to the inner contour of the lower port of the wiring cavity of the shell 201, and a sealing ring 12 is arranged at the inner contour of the lower port of the wiring cavity of the shell 201, and the sealing ring 12 can be used to seal the connection between the boss 11 and the wiring cavity of the shell 201.

[0056] An intermediate support plate 101 is provided on the column 1, and the intermediate support plate 101 is fixed at the upper end of the column 1, and a top surface 102 is provided at the upper end of the intermediate support plate 101; side support plates 103 are provided on both sides of the intermediate support plate 101, and gaps are provided between the two side support plates 103 and the intermediate support plate 101, and the upper ends of the side support plates 103 are fixed to the sides of the top surface 102, and the lower ends of the side support plates 103 are fixed to the upper end of the column 1.

[0057] The connector 2 includes a shell 201, which is connected to the end of the cable, and a wiring cavity is opened inside the shell 201; a conductive block 202 is fixedly connected to the top of the wiring cavity, in contact with the top surface 102, and the conductive block 202 is electrically connected to the cable; two clamping plates 203 are symmetrically arranged on both sides of the lower surface of the conductive block 202, and the upper ends of the clamping plates 203 are fixed to the lower surface of the conductive block 202.

[0058] The clamping plate 203 can be made of a material with good conductivity. The column 1, the middle support plate 101 and the side support plate 103 are integrally formed and have good conductivity. The column 1, the middle support plate 101, the side support plate 103, the conductive block 202 and the clamping plate 203 can be made of copper-plated nickel material.

[0059] Embodiment 2

[0060] like Figure 2-Figure 6 As shown, based on the first embodiment, in order to fix the connector 2 on the battery body and improve the stability of the connector 2 plugged into the column 1, the present embodiment can also improve the stability of the electrical connection.

[0061] The side support plate 103 comprises:

[0062] An arc-shaped first plate portion 1031, the lower end of which is fixed to the upper end of the column 1, and the middle portion of which is bent toward the middle support plate 101;

[0063] The inclined plate 1032 is arranged between the first plate portion 1031 and the top surface 102, the lower end of the inclined plate 1032 is fixedly connected to the upper end of the first plate portion 1031, the upper end of the inclined plate 1032 is fixedly connected to the side of the top surface 102, and the inclined plate 1032 gradually tilts toward the middle support plate 101 from bottom to top.

[0064] The middle support plate 101 is S-shaped. When the inclined plate 1032 is deformed and causes the top surface 102 to move upward and press against the lower surface of the conductive block 202, the S-shaped middle support plate 101 can produce corresponding deformation, which is conducive to the upward displacement of the top surface 102, thereby causing the top surface 102 to press against the lower surface of the conductive block 202.

[0065] The clamping plate 203 includes an elastic plate 2031, and the elastic plate 2031 is connected to the side of the top surface 102. Figure 3-Figure 5 As shown, the elastic plate 2031 is S-shaped, and the two ends of the elastic plate 2031 are respectively connected to the top surface 102 and the second plate portion 2032. The deformation of the elastic plate 2031 can cause the second plate portion 2032 to move, and the inflection point of the elastic plate 2031 close to the second plate portion 2032 is against the lower surface of the conductive block 202. When the elastic plate 2031 is deformed, the second plate portion 2032 is limited to swing left and right in the wiring cavity to prevent the second plate portion 2032 from moving upward as a whole to a large extent; the end of the elastic plate 2031 away from the top surface 102 is connected to the arc-shaped second plate portion 2032, and the curvature of the second plate portion 2032 is the same as that of the first plate portion 1031; when the connector 2 is plugged into the column 1, the outer arc surface of the second plate portion 2032 fits on the inner arc surface of the first plate portion 1031.

[0066] Two lifting blocks 3 are also provided inside the shell 201. The two lifting blocks 3 are symmetrically slidably connected on both sides of the shell 201. A first spring 6 for pressing the lifting blocks 3 downward is provided between the top of the lifting block 3 and the side wall of the shell 201. The bottoms of the two lifting blocks 3 extend into the wiring cavity and are provided with inclined pushing surfaces 301; two rotating columns 4 are symmetrically provided on both sides of the shell 201, and a top wheel 401 for lifting the lifting blocks 3 upward is fixed on the side wall of each rotating column 4; two driving arms 5 are symmetrically provided on both sides of the shell 201, and the two driving arms 5 are fixed at the ends of the rotating columns 4 on the same side; when the driving arms 5 swing, the driving arms 5 can rotate with the rotating columns 4.

[0067] When the rotating column 4 rotates, the top wheel 401 on the rotating column 4 rotates upward, and the upwardly rotating top wheel 401 pushes the lifting block 3 to move upward. When the top wheel 401 rotates to a position directly above the rotating column 4, the lifting block 3 moves up to the highest state. Conversely, when the top wheel 401 rotates downward with the rotating column 4, the top wheel 401 eliminates the pushing force on the lifting block 3, and the lifting block 3 moves downward.

[0068] The lower end of the second plate portion 2032 is provided with an inclined pressure-bearing surface 2033;

[0069] When the lifting block 3 moves upward, the pushing surface 301 contacts the pressure surface 2033 and pushes the lower end of the second plate portion 2032 to move.

[0070] Specific, combined Figure 3-Figure 5 After the lifting block 3 moves upward, the pushing surface 301 first contacts the pressure surface 2033, and the lifting block 3 continues to move upward, and the pushing surface 301 presses the pressure surface 2033 upward, causing the lower end of the second plate portion 2032 to move upward. At this time, the second plate portion 2032 is deformed by the force, that is, the middle part of the second plate portion 2032 is deformed toward the first plate portion 1031, so that the outer arc surface of the second plate portion 2032 and the inner arc surface of the first plate portion 1031 fit more closely, and the first plate portion 2032 is more tightly pressed against the inner arc surface of the first plate portion 1031. The cooperation between 1031 and the second plate portion 2032 can play a locking role, and can stably insert the connector 2 on the column 1. Moreover, when the second plate portion 2032 generates a top pressure on the first plate portion 1031, the first plate portion 1031 will also be deformed, and the connection between the first plate portion 1031 and the inclined plate 1032 will move toward the middle of the wiring cavity, and the inclined plate 1032 will move upward against the top surface 102, thereby making the top surface 102 and the conductive block 202 contact more closely.

[0071] In addition, when the inclined pushing surface 301 cooperates with the pressure surface 2033 to push the lower end of the second plate portion 2032 upward, under the action of the upward thrust of the pushing surface 301, the pressure surface 2033 will also slide on the pushing surface 301, causing the lower end of the second plate portion 2032 to move toward the middle of the wiring cavity, that is, the second plate portion 2032 generates a thrust on the first plate portion 1031, so that the outer arc surface of the second plate portion 2032 and the inner arc surface of the first plate portion 1031 fit more closely, thereby fixing the connector 2 on the battery body, that is, improving the stability of the connector 2 inserted into the column 1, and further improving the stability of the electrical connection.

[0072] Embodiment 3

[0073] like Figure 6-Figure 8 As shown, on the basis of the second embodiment, in this embodiment, the interiors of the two driving arms 5 are slidably connected with telescopic rods 7, the outer ends of the two telescopic rods 7 are fixed with locking rods 8, a locking groove 2011 is opened on the side wall of the shell 201, and the locking rod 8 is movably connected to the interior of the locking groove 2011; and a stopper 10 is slidably connected to the side wall of the shell 201 through a second spring 9, the upper end of the stopper 10 is movably inserted into the interior of the locking groove 2011, and a handle is fixed to one side of the stopper 10.

[0074] like Figure 7-Figure 8 As shown, when the top wheel 401 is located directly above the rotating column 4, the driving arm 5 is in a horizontal state. At this time, the locking rod 8 is opposite to the opening of the locking slot 2011. In this state, the stopper 10 is pulled downward by the handle to slide downward, and the upper end of the stopper 10 moves out from the inside of the locking slot 2011. The mouth of the locking slot 2011 opens, pushing the locking rod 8, and the telescopic rod 7 retracts into the inside of the driving arm 5. At the same time, the locking rod 8 enters the inside of the locking slot 2011, and the handle is released. The stopper 10 rebounds upward by the second spring 9, causing the stopper 10 to slide upward into the locking slot 2011. At this time, the stopper 10 locks the locking rod 8 in the inside of the locking slot 2011. In this state, the connector 2 is fixed to the battery body by the cooperation of the first plate portion 1031 and the second plate portion 2032.

[0075] On the contrary, if Figure 8 As shown, when the locking rod 8 slides out of the locking slot 2011, the driving arm 5 can rotate, and the driving arm 5 rotates with the rotating column 4, so that the top wheel 401 eliminates the upward pressure on the lifting block 3, that is, the upward thrust of the pushing surface 301 on the pressure surface 2033 disappears, causing the clamping force of the second plate portion 2032 on the first plate portion 1031 to be reduced or even disappear. In this state, the connector 2 can be easily pulled off the column 1, thereby facilitating the disassembly and assembly of the connector 2.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
