DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution. Example 1

[0032] like Figure 1As shown, this embodiment proposes a modular power supply based on a hollow battery in a pole 1. The basic structure of the modular power supply based on a hollow battery in a pole 1 is similar to that of a general power supply. Specifically, the modular power supply based on a hollow battery in a pole 1 in this embodiment includes a pole 1, and a cell winding 5 is surrounded by the outside of the pole 1. The combination of the pole 1 and the cell winding 5 is installed in a battery housing 9. In this embodiment, the pole 1 is one of the positive or negative poles of the battery, and the battery housing 9 is the other of the positive or negative poles of the battery. Therefore, the pole 1 and the battery housing 9 are two poles for supplying power to external electrical equipment. The first end face of the battery housing 9 has a first groove, and the first end of the pole 1 protrudes from the first end face of the battery housing 9. The second end face of the battery housing 9 has a boss structure, and the above-mentioned boss mechanism matches the size, shape and position of the first groove of the first end face of the battery housing 9. At the same time, the battery housing 9 has a second groove in the middle of the second end face, and the size, shape and position of this second groove match the protruding portion of the first end of the pole 1.

[0033] A plug 4 is provided at the end face of the first end of the pole 1, and a plug 4 is provided at the second end face of the battery housing 9 corresponding to the second groove. The plug 4 is used to protect the electrical / non-electrical equipment inside the pole 1. The plug 4 can be in the form of a film, paper, plug or other structure that performs a sealing function.

[0034] The pole 1 has a cavity inside, and at least one section of the two ends of the cavity is an open structure, so the pole 1 forms a tube body, or a tubular structure with one end closed. The first internal component 6, the second internal component 7, and the third internal component 8 can be installed in the internal cavity of the pole 1. The outer layer components of the first internal component 6, the second internal component 7, and the third internal component 8 are connected to the pole 1 and are nested inside each other. The first internal component 6, the second internal component 7, and the third internal component 8 are not limited to three layers, and can be one or more layers, and can be customized or assembled as needed.

[0035] A first external device 11 or a second external device 12 is disposed on the outer peripheral surface of the battery housing 9. The external device is not limited to two layers, and may be one layer or more layers, and may be customized or assembled as required.

[0036] In this embodiment, the outer circumference of the protruding portion of the first end of the pole 1 is provided with a pole external connection structure 2, and the inner circumference of the second groove in the middle of the second end of the battery housing 9 is provided with a pole internal connection structure 3.

[0037] In addition, a battery housing connection structure 10 is provided on the inner circumference of the first groove at the first end of the battery housing 9 , and a battery housing connection structure 10 is provided on the outer circumference of the boss structure at the second end of the battery housing 9 .

[0038] The battery in the above-mentioned embodiment 1 is a concave-convex modular power supply. Example 2

[0039] like Figure 2 As shown, based on the modular power supply in the above-mentioned embodiment 1, in this embodiment, the first end of the pole 1 is shorter, and the structure of the first end of the pole 1 is basically the same as the structure of the second end. At this time, the battery housing 9 corresponding to the first end of the pole 1 is also a second groove, and the inner annular surface of the second groove has a pole internal connection structure 3.

[0040] The battery in the above-mentioned embodiment 2 is a double-concave modular power supply. Example 3

[0041] like Figure 3 As shown, based on the modular power supply in the above-mentioned embodiment 1, in this embodiment, the second end of the pole 1 is longer, and the structure of the second end of the pole 1 is basically the same as the structure of the first end. At this time, both ends of the pole 1 protrude from the end surface of the battery casing 9, and the outer annular surface of the pole 1 near the end has a pole external connection structure 2.

[0042] The battery in the above-mentioned embodiment 3 is a double-convex modular power supply.

[0043] Based on the modular power supplies in the above-mentioned embodiments 1-3, various combinations of modular power supplies are proposed below.

[0044] like Figure 4 As shown, the present embodiment adopts the three concave-convex modular power supplies in Embodiment 1, and the three concave-convex modular power supplies are connected end to end at once, that is, the pole 1 of the rear concave-convex modular power supply is inserted into the second groove at the tail of the front concave-convex modular power supply, and at the same time, the boss structure at the tail of the front concave-convex modular power supply is inserted into the first groove at the front end of the rear concave-convex modular power supply.

[0045] At this time, the pole inner connection structure 3 at the tail of the first concave-convex modular power supply is connected to the pole outer connection structure 2 at the front of the second concave-convex modular power supply. At the same time, the battery shell connection structure 10 at the end surface connection of the two adjacent concave-convex modular power supplies is connected to each other. At the same time, an assembly gap A is left for assembly.

[0046] like Figure 5 As shown, when a concave-convex modular power supply and a double-concave modular power supply are assembled, the pole outer connection structure 2 at the front of the latter concave-convex modular power supply is connected to the pole inner connection structure 3 at the rear of the former double-concave modular power supply. At the same time, the battery shell connection structure 10 at the end surface connection of the two adjacent concave-convex modular power supplies is connected to each other. At the same time, an assembly gap A is left for assembly.

[0047] like Figure 6As shown, when a concave-convex modular power supply and a double-concave modular power supply are assembled, the pole outer connection structure 2 at the front of the latter concave-convex modular power supply is connected to the pole inner connection structure 3 at the head of the former double-concave modular power supply. At this time, the end faces at the assembly point all have the first groove, so there is no assembly gap.

[0048] like Figure 7 As shown, when two concave-convex modular power supplies are respectively installed on the two end surfaces of a double-concave modular power supply, the pole outer connection structure 2 at the front of the concave-convex modular power supply is connected to the pole inner connection structure 3 at both ends of the middle double-concave modular power supply. At this time, an assembly gap A is left on one side, and no assembly gap is left on the other side.

[0049] like Figure 8 As shown, when a double-convex modular power supply is assembled with a concave-convex modular power supply, the pole 1 at one end of the double-convex modular power supply is inserted into the second groove at the tail of the concave-convex modular power supply, and the battery casing connection structure 10 at the matching end is connected to each other.

[0050] like Fig. 9 As shown, a dual-convex modular power supply is assembled with two concave-convex modular power supplies.

[0051] like Fig.10 As shown, a double-convex modular power supply can also be assembled with two double-concave modular power supplies, and in this case, the tail ends of the two double-concave modular power supplies are both facing the double-convex modular power supply.

[0052] like Fig.11 As shown, a double-convex modular power supply can also be assembled with two double-concave modular power supplies, in which case the front end of the rear double-concave modular power supply is connected to the rear end of the double-convex modular power supply, and the front end of the double-convex modular power supply is connected to the rear end of the front double-concave modular power supply.

[0053] like Fig.12 As shown, the battery housing 9 can have different outer contours as required, such as a circular, hexagonal, rectangular or triangular cross section. Fig.13 As shown, the figure shows the state of multiple modular power supplies based on hollow batteries in the pole 1 being assembled with each other when the cross-section of the battery housing 9 is of different shapes. At this time, the modular power supplies based on the hollow batteries in the pole 1 can be connected in parallel with each other through conductors.

[0054] like Fig.14As shown, in this embodiment, the modular power supply is applied to lighting equipment. Taking the concave-convex modular power supply as an example, since the pole 1 is a hollow structure, the position of the upper end of the pole 1 can be electrically connected to the positive electrode 21 of the lighting equipment at the outside of the modular power supply corresponding to the position of the pole 1, and the battery housing 9 is electrically connected to the negative electrode 22 of the lighting equipment. At this time, the drive circuit 23 can be placed in the cavity inside the electrode to minimize the volume of the lighting equipment. At this time, the modular power supply is used alone.

[0055] like Fig.15 As shown, in this embodiment, the modular power supply is applied to a charging device 30. Taking the concave-convex modular power supply as an example, since the pole 1 is a hollow structure, the modular power supply can be used as a power supply, and an internal rotating mechanism 31 and a driving motor 32 are arranged inside the pole 1. The output end of the other side of the driving motor 32 extends to the outside of the tail of the modular power supply through the driving shaft 33 and is connected to the external rotating mechanism 34. At this time, the modular power supply is used alone.

[0056] This embodiment only exemplifies some variations based on the basic structure. In other embodiments, the length and position of the pole 1 relative to the end face of the battery casing 9 can be adaptively changed according to actual needs, and they can be spliced ​​together for use. The above splicing includes series connection, parallel connection or a combination thereof. They can also be used alone and in conjunction with external electrical equipment according to actual needs.

[0057] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
