Fig. 1 to 5 show a specific embodiment of the battery module of the present application, which includes a plurality of cylindrical upper cells 5 and a plurality of cylindrical lower cells 6, and the negative terminal of the bottom of the upper cells 5 and the positive terminal of the top of the lower cells 6 are connected in series by a cell series assembly. Also, the upper battery 5 and the lower battery 6 each include: the battery comprises a cylindrical battery shell, an inner core accommodated in the battery shell, and a positive electrode cap and a negative electrode cap which are respectively arranged at two axial ends of the battery shell; and the positive pole of the inner core is electrically connected with the positive pole cap, and the negative pole of the inner core is electrically connected with the negative pole cap and the battery shell, namely the positive pole cap is used as the positive pole leading-out terminal of the battery, and the negative pole cap and the battery shell are both used as the negative pole leading-out terminal of the battery.
The battery series assembly also includes a battery holder 1 made of an insulating material and a series conductive sheet 2 mounted in the battery holder 1, as in the conventional battery series assembly.
The key improvement of this embodiment lies in that the battery holder 1 and the series connection conducting strip 2 adopt a completely new and ingenious structural style, which is specifically as follows:
the battery support 1 is made of insulating plastic materials, and a plurality of battery inserting holes 101 are vertically formed in the battery support in a through mode. The series conductive plate 2 made of a metal material is fitted into the battery insertion hole 101. The series conductive sheet 2 includes: a generally circular base sheet 201, a plurality of upper claws 202 integrally extending upward from the base sheet 201, and a plurality of lower claws 203 integrally extending downward from the base sheet 201. Each of the upper spring claw 202 and the lower spring claw 203 is of a bent structure and is spaced around the center of the substrate 201. The upper and lower resilient claws 202 and 203 are provided in a bent structure in order to have elastic deformability in the radial direction of the battery insertion hole 101 so as to tightly hold the battery after the battery is inserted. Each of the upper and lower spring claws 202 and 203 is in (elastic) abutting contact with a hole wall of the battery insertion hole 101.
The four upper spring claws 202 and the four lower spring claws 203 are respectively arranged, and different from the existing eight-claw disc, the series connection conducting strip is provided with the spring claws at two axial sides of the substrate, and the existing eight-claw disc is only provided with the spring claws at one side of the substrate.
The series-connected conductive sheets 2 can be produced by integrally stamping a metal sheet with a stamping apparatus.
The negative terminal at the bottom of the upper cell 5 is inserted downward into the cell insertion hole 101, and the positive terminal at the top of the lower cell 6 is inserted upward into the cell insertion hole 101. The radius of the upper battery 5 and the small battery 6 is only slightly smaller than the diameter of the battery insertion hole 101, so that the upper spring claw 202 is clamped between the upper battery 5 and the battery insertion hole 101 and elastically deformed (in the radial direction of the battery insertion hole) by the clamping force, and the lower spring claw 203 is clamped between the lower battery 6 and the battery insertion hole 101 and elastically deformed by the clamping force. The upper battery 5 and the lower battery 6 are tightly held by the elasticity of the series connection conducting strips 2, so that the upper battery and the lower battery are fixed with the battery bracket 1 without welding the upper battery and the lower battery with the series connection conducting strips 2. Because the battery shell of the upper battery 5 is the negative electrode of the battery, the upper elastic claw 202 of the series conducting strip 2 tightly holds the battery shell at the negative electrode end of the upper battery 5, the conductive connection between the negative electrode of the upper battery 5 and the series conducting strip 2 is realized.
As already mentioned above, the battery cases of the upper battery 5 and the lower battery 6 are conductively connected to the negative electrode of the battery core, which would result in a short circuit if the positive electrode cap of the battery is conductively connected to the battery case. When the positive terminal of the lower battery 6 is inserted into the battery insertion hole 101 and is held tightly by the elastically deformed lower spring claw 203, the lower spring claw 203 of the series conductive piece 2 is brought into conductive connection with the negative terminal of the lower battery 6 if it directly contacts the battery case at the positive terminal of the lower battery. In order to realize the series connection of the lower battery 6 and the upper battery 5, the positive electrode (specifically, the positive electrode cap) of the lower battery 6 must be electrically connected to the series conducting strip 2, so that the series conducting strip 2 is simultaneously connected to the positive electrode and the negative electrode of the lower battery 6, thereby causing the short circuit of the lower battery. In this respect, the present embodiment is further modified as follows:
an insulating sleeve 3 surrounding the battery shell of the lower battery 6 is sleeved at the positive end of the lower battery 6, and a conductive sleeve 4 in conductive contact connection with the positive cap of the lower battery 6 is sleeved outside the insulating sleeve 3. The conductive sleeve 4 is inserted upward into the battery insertion hole 101, and the lower spring claw 203 of the series conductive piece 2 is clamped between the conductive sleeve 4 and the battery insertion hole 101 and elastically deformed by the clamping force. That is, the lower claws 203 of the series-connected conductive pieces 2 do not directly hold (contact) the lower battery 6, but indirectly hold the lower battery 6 by directly holding the conductive sleeve 4 fitted over the lower battery 6.
In this way, the conductive sleeve 4 is insulated from the battery case of the lower battery 6 by the insulating sleeve 3, and the conductive connection of the conductive sleeve 4 and the positive electrode cap of the lower battery 6 is not affected. After the assembly is completed, the positive electrode cap of the lower battery 6 is in conductive connection with the conductive sleeve 4, the conductive sleeve 4 is in conductive contact connection with the lower elastic claw 203 of the series conductive sheet 2, and the insulating sleeve 3 insulates and separates the conductive sleeve 4 from the battery shell (the battery shell is the negative electrode of the lower battery) of the lower battery 6, so that the lower battery is prevented from short circuit.
The conductive sleeve 4 includes a circular conductive ring sleeve and a conductive bottom wall integrally sealed (i.e., an opening at one end of the ring sleeve is sealed) and disposed at one axial end of the ring sleeve. The positive electrode cap of the lower battery 6 is in conductive contact with the conductive bottom wall of the conductive sleeve 4. In order to prevent the lower battery 6 from being separated from the conductive sleeve 4, a positive electrode cap of the lower battery 6 can be welded and fixed with the conductive sleeve 6.
Further, in order to facilitate the installation and positioning of the insulating sheath 3 and at the same time prevent the insulating sheath 3 from easily moving axially on the lower battery 7 after the assembly is completed, the present embodiment provides the insulating sheath 3 in a structure including: the insulating ring cover of ring shape, an organic whole set up in this insulating ring cover axial one end and radial inward extension's ring shape insulating diapire. Part of the positive electrode cap of the lower battery 6 extends out of (an inner hole of) the insulating bottom wall of the insulating sleeve 3 and is welded and fixed with the conductive bottom wall of the conductive sleeve 4.
Further, the positive electrode cap of the lower battery 6 includes a pole projecting axially outward, which projects out of (the inner hole of) the insulating bottom wall of the insulating sleeve 3 and is welded and fixed to the bottom wall of the conductive sleeve 4.
During assembly, when the insulating sleeve 3 is sleeved downwards into the upper end of the lower battery 6 and the insulating sleeve presses the upper end surface of the battery, the insulating sleeve 3 is installed in place, and then the conductive sleeve 4 is sleeved until the conductive sleeve cannot move downwards, and at the moment, the conductive sleeve 4 is in conductive contact with the positive electrode of the battery. In order to prevent the positive electrode cap of the lower battery 6 from being separated from the conductive sleeve 4 due to vibration during use, the conductive sleeve 4 and the positive electrode cap of the lower battery can be further welded and fixed.
Further, in the present embodiment, a heat insulating sheet 7 is further disposed in the battery insertion hole 101, sandwiched between the conductive cover 4 and the substrate 201, and the heat insulating sheet 7 is preferably a mica sheet or a ceramic sheet.
And, the positive terminal of the upper battery 6 is also sleeved with the insulating sleeve 3 and the conductive sleeve 4, so as to connect other batteries above the upper battery 6 in series.
For facilitating the installation location of series connection conducting strip 2 in battery cartridge hole 101, reduce the possibility that series connection conducting strip 2 breaks away from in battery cartridge hole 101 simultaneously, this embodiment sets up battery cartridge hole 101 to the step hole structure, and it includes: the hole-forming device comprises an upper hole section with a smaller hole diameter, a lower hole section with a larger hole diameter and an annular step formed between the upper hole section and the lower hole section. The substrate 201 of the series conducting strip 2 is abutted upwards against the annular step, the upper spring claw 202 of the series conducting strip 2 is arranged at the upper hole section, and the lower spring claw 203 of the series conducting strip 2 is arranged at the lower hole section.
In order to further reduce the possibility that the series conductive tab 2 falls off from the battery insertion hole 101 after the assembly is completed, the upper spring claw 202 and the lower spring claw 203 of the present embodiment are integrally formed with a plurality of protrusions, and the hole wall of the battery insertion hole 101 is formed with a plurality of radially recessed grooves. After the assembly is completed, the salient points are embedded into the grooves under the action of the radially outward extrusion force of the upper battery and the lower battery, so that the series connection conducting strips 2 are prevented from moving axially.
It should be noted that: the battery shell of some batteries is not conductively connected with the positive electrode or the negative electrode of the battery core, so that the positive electrode end of the lower battery 6 is not required to be sleeved with an insulating sleeve and a conductive sleeve, the positive electrode end of the upper part of the lower battery 6 can be directly inserted into the battery insertion hole 101 and tightly held by the lower elastic claw 203, and meanwhile, the positive electrode cap of the lower battery 6 is ensured to be in conductive contact with the substrate 201.
The above embodiments are only for illustrating the technical concepts and features of the present application, and the purpose of the embodiments is to enable people to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application. All equivalent changes and modifications made according to the spirit of the main technical scheme of the application are covered in the protection scope of the application.
