DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The utility model provides a sodium ion starting battery for an internal combustion engine.

[0028] like Figure 1 As shown, it includes a shell 1 and a top cover 2 installed on the shell 1, the top cover 2 is provided with a positive electrode and a negative electrode of the battery, a battery filling block 3 is installed in the shell 1, a plurality of embedding grooves are evenly opened on the battery filling block 3, a sodium ion battery 4 is installed in the embedding groove, and a plurality of series components are arranged on the inner walls of the shell 1 and the top cover 2, and a plurality of the sodium ion batteries 4 are connected together through the series components to form a sodium ion starting battery pack.

[0029] like Figure 2 , 7 As shown, a plurality of extrusion grooves 5 are provided at positions corresponding to the series components on the upper and lower sides of the battery filling block 3, and a connecting groove is provided between two adjacent extrusion grooves 5. A resistance bracket 6 is placed in the extrusion groove 5 and the connecting groove. An adjusting screw is threadedly connected in the extrusion groove 5. The resistance bracket 6 is placed on the end of the adjusting screw. The resistance bracket 6 is in resistance to the top of the sliding connecting rod 8. The height of the adjusting screw in the extrusion groove 5 is changed by threading, and the height of the resistance bracket 6 in the battery filling block 3 is changed, that is, the sliding distance of the resistance bracket 6 against the sliding connecting rod 8, so as to adjust the tilting height of the elastic bow piece 9, so that the elastic bow piece 9 can tightly resist the positive and negative electrodes of the sodium ion battery 4 to maintain good electrical contact.

[0030] like Figure 4 , 5 , 6, the series assembly includes a plurality of sliding bases 7 fixed on the outer shell 1 and the top cover 2, a sliding connecting rod 8 slidingly penetrated on the top of the sliding base 7, and an elastic bow piece 9 with one end detachably fixed on the sliding connecting rod 8 and the other end extending toward the positive and negative electrodes of the sodium ion battery 4. The elastic bow piece 9 is abutted and connected to the positive and negative electrodes of the sodium ion battery 4, and the battery filling block 3 is abutted on the sliding connecting rod 8. The sliding base 7 includes a mounting sleeve 71 fixed on the inner wall of the outer shell 1 and the top cover 2 and a mounting sleeve 71 extending from the outer wall of the mounting sleeve 71 toward the positive and negative electrodes. The guide slider 72 extends in the direction of the sodium ion battery 4, and the side wall of the guide slider 72 is set as an inclined sliding surface. The elastic bow piece 9 includes a horizontal portion 91 integrally formed and fixed on the sliding link 8, a connecting portion 92 whose horizontal end is in contact with the positive and negative electrodes of the sodium ion battery 4, and a supporting sliding portion 93 connected and inclined between the horizontal portion 91 and the connecting portion 92. The supporting sliding portion 93 slides and contacts on the inclined sliding surface of the guide slider 72, and the inclination angle of the supporting sliding portion 93 is greater than the inclination of the inclined sliding surface.

[0031] Further, the sliding link 8 is made of insulating material, a conductive ring plate 10 is fixed in the middle of the sliding link 8, a positioning nut 11 is threadedly connected to the upper part of the sliding link 8, and the horizontal part 91 is inserted and fixed between the conductive ring plate 10 and the positioning nut 11. By screwing and squeezing the positioning nut 11, the disassembly and assembly of the elastic bow piece 9 can be realized. To meet the series-parallel design of sodium-ion batteries, any number of elastic bow pieces 9 can be disassembled and assembled arbitrarily. A conductive path is formed among the sodium-ion battery 4, the elastic bow piece 9, and the conductive ring plate 10, enabling the series connection paths of multiple sodium-ion batteries 4 in the battery filling block 3 to form a sodium-ion starting battery pack. A positioning slot is provided on the conductive ring plate 10, and a limiting bump 15 that is in concave-convex fit with the positioning slot is provided on the horizontal part 91. The setting of the limiting bump 15 can play a limiting role when the elastic bow piece 9 is installed on the sliding link 8, enabling the elastic bow piece 9 to maintain the required extension direction.

[0032] As Figure 6 shown, a limiting block 12 is provided on one side of the supporting sliding part 93 facing the guiding slider 72. The inner side wall of the limiting block 12 is vertically arranged, a limiting sliding groove is opened in the middle of the limiting block 12, and the width of the limiting sliding groove is equal to the width of the guiding slider 72. The limiting sliding groove is slidably buckled on the guiding slider 72. The limiting block 12 plays a limiting role, and through the limitation of the guiding slider 72, the elastic bow piece 9 can just extend towards the positive and negative electrodes of the sodium-ion battery 4, preventing the elastic bow piece 9 from rotating on the sliding link 8, causing the positive and negative electrodes of the elastic bow piece 9 to be misaligned with those of the sodium-ion battery 4 and resulting in an open circuit.

[0033] As Figure 5 、 6 shown, a clamping block sliding groove is provided in contact with the sliding link 8, a plugging clamping block 13 is slidably connected in the clamping block sliding groove, a plugging inclined surface is provided at the front end of the plugging clamping block 13, a plugging clamping spring 14 is connected between the plugging clamping block 13 and the clamping block sliding groove, a limiting ring is provided at the top of the mounting sleeve 71, and the upper edge of the plugging clamping block 13 is clamped under the limiting ring. The setting of the plugging clamping block 13 can clamp the sliding link 8 on the sliding base 7, preventing the inverted sliding link 8 from falling out of the sliding base 7 of the top cover 2 after installation.

[0034] Working principle:

[0035] In the present utility model, the appropriate number and extending direction of elastic bow pieces 9 can be selected to be installed on the sliding connecting rod 8 according to the series-parallel design of the sodium-ion start-up storage battery to meet the design requirements. The positioning nut 11 can be screwed on the sliding connecting rod 8 to squeeze and fix the horizontal part 91 of the elastic bow piece 9 on the conductive ring piece 10. Furthermore, through the mutual cooperation of the limiting bump 15 and the positioning slot hole, the extending direction of the elastic bow piece 9 is limited to ensure that the connecting part 92 of the elastic bow piece 9 can abut against the positive and negative electrodes of the sodium-ion battery 4, so as to form a conductive path among the sodium-ion battery 4, the elastic bow piece 9 and the conductive ring piece 10, thereby forming a sodium-ion start-up storage battery pack.

[0036] After assembling the series components, the sliding connecting rod 8 can be passed through the sliding base 7 and used in cooperation with the plug-in card block 13 and the plug-in spring 14 to be clamped in the limiting ring of the sliding base 7, which can prevent the series components from sliding out of the sliding base 7 when the top cover 2 is inverted.

[0037] For the assembly of the sodium-ion start-up storage battery, the top cover 2 is buckled on the outer shell 1, and the top cover 2, the outer shell 1 and the battery filling block 3 are mutually squeezed and fixed. The abutting bracket 6 on the battery filling block 3 abuts against the top of the sliding connecting rod 8, so that the sliding connecting rod 8 slides in the installation sleeve 71. At the same time, the sliding connecting rod 8 will squeeze the elastic bow piece 9, and the supporting sliding part 93 of the elastic bow piece 9 abuts against the inclined sliding surface of the guiding slider 72. Through the inclined surface extrusion, the connecting part 92 and the supporting sliding part 93 are warped outwards to abut against the positive and negative electrodes of the sodium-ion battery 4, forming a tightly fitting connection, forming a good circuit connection, and jointly forming the sodium-ion start-up storage battery.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
