[0053] Embodiment 1:

[0054] This embodiment provides an energy storage power supply, as Figures 1 - 8 shown, the energy storage power supply includes a battery module (not shown in the figure), a housing 200, and a vehicle charger assembly 100. A receiving cavity 201 is formed in the side wall of the housing 200. Both the battery module and the vehicle charger assembly 100 are installed in the receiving cavity 201. The vehicle charger assembly 100 is electrically connected to the battery module. A vehicle charger socket 10 is provided in the vehicle charger assembly 100, and a vehicle charger jack 202 is provided on the housing 200. An external electrical connector passes through the vehicle charger jack 202 and is electrically connected to the vehicle charger socket 10.

[0055] Furthermore, as Figures 1 - 8As shown, the vehicle charger assembly 100 further includes a circuit board 50, conductive elastic pieces, and a vehicle charger bracket 20. The circuit board 50 is provided with an avoidance through-hole 51. The conductive elastic pieces include a positive conductive elastic piece 40 and a negative conductive elastic piece 30. The vehicle charger bracket 20 is installed on the circuit board 50. The vehicle charger bracket 20 can define the connection and installation positions between the conductive elastic pieces and the circuit board 50. The conductive elastic pieces are electrically connected to the circuit board 50. The vehicle charger socket 10 passes through the avoidance through-hole 51 and is installed on the vehicle charger bracket 20. The vehicle charger socket 10 has a positive electrode and a negative electrode. The positive electrode of the vehicle charger socket 10 is elastically connected to the positive conductive elastic piece 40, and the negative electrode of the vehicle charger socket 10 is elastically connected to the negative conductive elastic piece 30.

[0056] Specifically, the vehicle charger assembly 100 is provided with a positive conductive elastic piece 40 and a negative conductive elastic piece 30. The positive and negative electrodes of the vehicle charger socket 10 are both electrically connected to the circuit board 50 through the elastic piece structure. On the one hand, the soldering process between the negative electrode of the vehicle charger socket 10 and the avoidance through-hole 51 of the circuit board 50 is omitted. On the other hand, the positive electrode of the vehicle charger socket 10 does not need to be connected to the circuit board 50 through a lead, simplifying the electrical connection structure between the circuit board 50 and the vehicle charger socket 10, reducing the manufacturing cost, and making the assembly operation more convenient and improving the production efficiency.

[0057] In addition, the vehicle charger bracket 20 is used for the installation and fixation of the vehicle charger socket 10 on the one hand. Compared with the installation method of directly clamping the vehicle charger socket 10 through the elastic piece, the vehicle charger socket 10 is not easy to slide or deflect, and the installation stability is higher. On the other hand, the vehicle charger bracket 20 positions the conductive elastic pieces on the circuit board 50, playing a role in positioning the conductive elastic pieces during the welding between the conductive elastic pieces and the circuit board 50, so as to improve the welding reliability between the conductive elastic pieces and the circuit board 50 and reduce the difficulty of production and manufacturing.

[0058] Exemplarily, as Figure 2 shown, a locking member 203 is arranged in the accommodation cavity 201. The circuit board 50 is locked to the housing 200 through the locking member 203. The inner wall of the accommodation cavity 201 presses the vehicle charger bracket 20 against the circuit board 50. The housing 200 is provided with a vehicle charger jack 202 for the vehicle charger socket 10 to pass through. Specifically, a plurality of locking members 203 are arranged on the inner side wall of the housing 200. The locking member 203 is specifically a snap-fastening buckle. The circuit board 50 is snap-fastened to the inner side wall of the housing 200 through the locking member 203. When installing the vehicle charger assembly 100, the vehicle charger socket 10 is passed through the vehicle charger jack 202, and then the circuit board 50 is snap-fastened to the housing 200. At this time, the vehicle charger socket 10 is docked with the vehicle charger bracket 20, playing an auxiliary positioning role in the installation of the vehicle charger bracket 20 and the circuit board 50 part. The installation structure of the vehicle charger assembly 100 is simple, and the internal structure of the housing 200 is neat and beautiful. In other embodiments, the locking member 203 can also be other locking structures such as bolts.

[0059] Exemplarily, as Figure 2 、Figure 5 and Figure 6 As shown in Figure 6 , the vehicle charger socket 10 includes a vehicle charger barrel 11 and a positive electrode connector 12. An installation through hole 211 is provided on the vehicle charger bracket 20. The vehicle charger barrel 11 passes through the vehicle charger bracket 20 and the circuit board 50, specifically passing through the installation through hole 211 and the clearance through hole 51. The vehicle charger barrel 11 serves as the negative electrode of the vehicle charger socket 10 and is electrically connected to the negative electrode conductive elastic sheet 30. The negative electrode conductive elastic sheet 30 extends into the inner wall of the installation through hole 211 and presses against the outer wall of the vehicle charger barrel. The positive electrode connector 12 is fixed to the vehicle charger barrel 11 and is insulated from the vehicle charger barrel 11. The positive electrode connector 12 serves as the positive electrode of the vehicle charger socket 10 and is electrically connected to the positive electrode conductive elastic sheet 40. Specifically, an insulating sheet is fixedly provided at the inner end of the vehicle charger barrel 11. The positive electrode connector 12 is clamped and fixed through the insulating sheet. The insulating sheet simultaneously serves the functions of clamping and installing the positive electrode connector 12 and electrically isolating the positive electrode connector 12 and the vehicle charger barrel 11.

[0060] In this embodiment, as Figure 5 and Figure 6 shown, the vehicle charger socket 10 further includes a positive electrode elastic sheet 14. A relief slot hole 111 is formed on the side wall of the vehicle charger barrel 11. One part of the positive electrode elastic sheet 14 is fixed to one end of the positive electrode connector 12 located inside the vehicle charger barrel 11, and the other part of the positive electrode elastic sheet 14 passes through the relief slot hole 111 and is elastically connected to the positive electrode conductive elastic sheet 40.

[0061] Exemplarily, as Figures 4 - 6 shown, the positive electrode elastic sheet 14 is arranged in a U-shaped structure, the middle part of which is fixed to the positive electrode connector 12. Relief slot holes 111 are formed on both opposite sides of the side wall of the vehicle charger barrel 11. The two end parts of the positive electrode elastic sheet 14 are respectively exposed through the two relief slot holes 111. There are two positive electrode conductive elastic sheets 40, and the two positive electrode conductive elastic sheets 40 respectively press against the outer side wall of the positive electrode elastic sheet 14 through the relief slot holes 111.

[0062] Exemplarily, the number of the negative electrode conductive elastic sheets 30 is at least two, and at least two negative electrode conductive elastic sheets 30 are arranged at intervals around the circumference of the vehicle charger bracket 20. As Figure 4 and Figure 7 shown, in this embodiment, the number of the negative electrode conductive elastic sheets 30 is also set to two, and the two positive electrode conductive elastic sheets 40 and the two negative electrode conductive elastic sheets 30 are arranged alternately around the circumference of the vehicle charger bracket 20.

[0063] Exemplarily, as Figure 4 and Figure 7 shown, the vehicle charger bracket 20 includes a cylindrical part 21 and a stepped part 22. An installation through hole 211 is provided in the cylindrical part 21 for the vehicle charger barrel 11 to pass through and be installed. The stepped part 22 is arranged on the outer peripheral part of the cylindrical part 21. During installation, the cylindrical part 21 passes through the clearance through hole 51, and the stepped part 22 presses against the circuit board 50, playing a role of axial and radial pre-positioning in the installation between the circuit board 50 and the vehicle charger bracket 20.

[0064] Exemplarily, the negative conductive elastic sheet 30 and the positive conductive elastic sheet 40 have the same structure, both being metal elastic sheets. Here, the negative conductive elastic sheet 30 is taken as an example to illustrate the structure of the conductive elastic sheet and its cooperation relationship with the vehicle charger holder 20:

[0065] As Figure 4 , Figure 7 and Figure 8 shown, one end of the negative conductive elastic sheet 30 is set as the pressing end 31, and the other end is set as the fixed end 32. Among them, the pressing end 31 is elastically connected to the vehicle charger socket 10, and the fixed end 32 is electrically connected to the circuit board 50. Specifically, the pressing end 31 of the negative conductive elastic sheet 30 is a movable end. The pressing end 31 penetrates from the inner wall of the mounting through hole 211, and the pressing end 31 arches towards the center direction of the mounting through hole 211 to press against the outer wall of the vehicle charger cylinder 11. A elastic sheet limiting groove 212 extending along the axial direction thereof is provided on the inner side wall of the mounting through hole 211. A relief notch 23 is provided on the cylindrical part 21 or the stepped part 22 corresponding to the elastic sheet limiting groove 212. The negative conductive elastic sheet 30 penetrates through the relief notch 23, and the pressing end 31 is limited in the elastic sheet limiting groove 212. A elastic sheet jack 53 is also provided on the circuit board 50. The fixed end 32 penetrates through the elastic sheet jack 53 and is electrically connected to the circuit board 50 through soldering in a soldering furnace.

[0066] Exemplarily, as Figure 4 and Figure 7 shown, a mounting seat 24 is provided on the stepped part 22. The mounting seat 24 is arranged outside the relief notch 23. The conductive elastic sheet penetrates through the mounting through hole through the relief notch 23, and the conductive elastic sheet is limited and installed on the mounting seat 24.

[0067] Exemplarily, a positioning post 25 is provided on one of the mounting seat 24 and the conductive elastic sheet, and a positioning hole 26 is provided on the other. The positioning post 25 penetrates through the positioning hole 26. In this embodiment, as Figure 4 , Figure 7 and Figure 8 shown, the mounting seat 24 is provided with a positioning hole 26. One end (i.e., the fixed end 32) of the conductive elastic sheet electrically connected to the circuit board 50 is set as a columnar structure, specifically a cylindrical structure. The fixed end 32 serves as the positioning post 25 and sequentially penetrates through the positioning hole 26 and the elastic sheet jack 53 and is fixed to the circuit board 50 through soldering in a soldering furnace.

[0068] Exemplarily, the vehicle charger holder 20 can also be directly fixedly connected to the circuit board 50 through a snap structure.

[0069] Embodiment Two:

[0070] As Figures 9 - 11 shown, on the basis of Embodiment One, this embodiment provides another vehicle charger assembly, and the difference between it and Embodiment One is that:

[0071] The positive conductive elastic sheet extends to the rear end of the vehicle charger cylinder 11, and the positive conductive elastic sheet does not penetrate into the installation through hole of the vehicle charger bracket 20. One end of the positive connector 12 passes through the vehicle charger cylinder 11 and is elastically connected to the positive conductive elastic sheet.

[0072] Furthermore, the structure of the negative conductive elastic sheet 30 in this embodiment and its cooperation structure with the vehicle charger bracket 20 are also different. As Figure 10 and Figure 11 shown, the mounting seat 24 is provided with positioning posts 25, the negative conductive elastic sheet 30 is provided with positioning holes 26, the positioning holes 26 are arranged between the pressing end 31 and the fixed end 32, and the circuit board 50 is provided with positioning reference holes 52. The positioning posts 25 are sequentially inserted through the positioning holes 26 and the positioning reference holes 52 to limit the negative conductive elastic sheet 30 between the vehicle charger bracket 20 and the circuit board 50. Specifically, for each negative conductive elastic sheet 30, two positioning posts 25 are provided on the mounting seat 24. Correspondingly, two positioning holes 26 on the negative conductive elastic sheet 30 and two positioning reference holes 52 on the circuit board 50 are also provided to improve the stability and reliability of the positioning and installation of the negative conductive elastic sheet 30.

[0073] Specifically, as Figure 11 shown, the negative conductive elastic sheet 30 further includes a transition section 33. The fixed end 32 and the pressing end 31 are respectively connected to both ends of the transition section 33 and extend in opposite directions, and the positioning hole 26 is arranged on the transition section 33.

[0074] In addition, in this embodiment, the step portion 22 is provided at the end of the cylindrical portion 21. The step portion 22 presses against the circuit board 50. The relief notch 23 is opened on the step portion 22. The relief through hole 51 is communicated with the installation through hole 211, and the vehicle charger socket 10 is inserted through the relief through hole 51 and the installation through hole 211.

[0075] Exemplarily, as Figure 9 and Figure 11 shown, a snap structure is provided between the vehicle charger socket 10 and the vehicle charger bracket 20 to limit the rotation angle of the vehicle charger socket 10 around the axis in the installation through hole 211. Specifically, a clamping protrusion 27 is provided on the inner wall of the installation through hole 211, and a clamping groove 13 is provided on the outer side wall of the vehicle charger cylinder 11. When the clamping protrusion 27 is snapped into the clamping groove 13, at the same time, multiple conductive elastic sheets also clamp the outer wall of the vehicle charger socket 10. The vehicle charger socket 10 and the vehicle charger bracket 20 are fixed to each other, restricting the rotation of the vehicle charger socket 10 around the axis in the installation through hole 211, and maintaining the vehicle charger socket 10 at an angle that is correctly electrically connected to the negative conductive elastic sheet 30 and the positive conductive elastic sheet 40.

[0076] Embodiment Three:

[0077] Based on Embodiment 2, this embodiment provides another vehicle charger component, which is different from Embodiment 2 in that:

[0078] The conductive elastic sheet does not include the positive conductive elastic sheet, and one end of the positive connector passes through the vehicle charger cylinder and is electrically connected to the circuit board through a wire.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
