DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pole 100 for use as an electrode of a power supply device 200. The pole 100 includes a base 10 and a pole body 20. The base 10 is used to connect to the housing 210 of the power supply device 200. The pole body 20 includes a first end face 21 and a second end face 22. The first end face 21 and the second end face 22 are arranged opposite each other and connected to the base 10. The pole body 20 is used to electrically connect to an external wire 310. The outer diameter of the pole body 20 gradually increases from the first end face 21 to the second end face 22.

[0039] The pole 100 proposed in the embodiment of the present invention can prevent the external wire 310 from falling off the pole body 20 by setting the outer diameter of the pole body 20 to gradually increase from the first end face 21 to the second end face 22, thereby improving the reliability of the connection between the pole 100 and the external wire 310.

[0040] In some embodiments, the base 10 and the pole body 20 are integrally formed. This embodiment provides the pole 100 with greater overall strength and a more reliable connection. Of course, the base 10 and the pole body 20 are not limited to being integrally formed. For example, in other embodiments, the base 10 and the pole body 20 may be separate components that are mechanically coupled, such as by screw fastening or welding.

[0041] In some embodiments, the base 10 and the pole body 20 are integrally processed or injection molded from metal materials.

[0042] In some embodiments, the pole 100 is a solid of revolution. Solids of revolution are easy to manufacture, which can improve production efficiency and reduce costs. Of course, the pole body 20 is not limited to a solid of revolution and can also be other shapes, such as a cube, depending on actual design needs.

[0043] In some embodiments, the pole body 20 is a solid of revolution. Solid of revolution is easy to manufacture, which can improve production efficiency and reduce costs. Of course, the pole body 20 is not limited to a solid of revolution and can also be other shapes, such as a cube, depending on actual design requirements.

[0044] like Figure 3 As shown, in some embodiments, the pole body 20 further includes a first outer peripheral surface 23, which is located between the first end surface 21 and the second end surface 22. The first outer peripheral surface 23 is provided with a first rough structure 231. The first rough structure 231 can increase the friction force of the first outer peripheral surface 23, so that the external wire 310 and the pole body 20 are not easily rotated relative to each other.

[0045] like Figure 3 As shown, in some embodiments, the first rough structure 231 includes one of a protrusion and a knurling. It should be noted that when the first rough structure 231 includes a knurling, it can be one of a straight knurling, a diagonal knurling, and a cross-knurling.

[0046] like Figure 2As shown, in some embodiments, the base 10 includes a first boss 11, a second boss 12, and a connecting portion 13. The first boss 11 is connected to the first end surface 21, the second boss 12 is spaced apart from the first boss 11, and the connecting portion 13 is connected between the first boss 11 and the second boss 12. The outer diameter of the connecting portion 13 is smaller than the outer diameters of the first boss 11 and the second boss 12, so that a groove 14 is formed between the first boss 11 and the second boss 12. In this embodiment, when the base 10 is fixedly connected to the housing 210 of the power supply device 200 through secondary injection molding, the plastic body of the housing 210 can be embedded in the groove 14 of the base 10, ensuring a secure connection between the base 10 and the housing 210 and preventing the pole 100 from falling off the housing 210.

[0047] It should be noted that the base 10 is not limited to the above-mentioned structure. For example, in some other embodiments, such as Figure 4 As shown, the base 10 is a single-layer structure. The term "single-layer structure" refers to a single-layer structure, such as a cylinder, rather than a multi-layer structure, such as an "I" shape. In this embodiment, by configuring the base 10 as a single-layer structure, the processing and manufacturing of the base 10 is facilitated, thereby improving production efficiency.

[0048] It should be noted that when the base 10 is a single-layer structure, in some embodiments, the base 10 is a cylinder or a cone. Figure 5 As shown, when the base 10 is a cone, it can be a right cone. The term "right cone" refers to a gradually increasing outer diameter of the base 10 from the second end face 22 toward the first end face 21. In this embodiment, when the base 10 is fixedly connected to the housing 210 of the power supply device 200 through secondary injection molding, the base 10 is securely engaged with the housing 210 of the power supply device 200 via its outer circumferential surface. When the pole body 200 is pulled by an external force, the pole 100 is not easily dislodged from the housing 210 of the power supply device 200.

[0049] like Figure 3 As shown, in some embodiments, the base 10 includes a third end surface 15, a fourth end surface 16, and a second outer peripheral surface 17. The third end surface 15 and the fourth end surface 16 are disposed opposite each other and connected to the first end surface 21. The second outer peripheral surface 17 is located between the third end surface 15 and the fourth end surface 16. The second outer peripheral surface 17 is provided with a second rough structure 171. The second rough structure 171 can increase the friction of the second outer peripheral surface 17, thereby preventing relative rotation between the base 10 and the housing 210 of the power supply device 200.

[0050] like Figure 3As shown, in some embodiments, the second rough structure 171 includes one of a protrusion and a knurling. It should be noted that when the second rough structure 171 includes a knurling, it can be one of a straight knurling, a diagonal knurling, and a cross-knurling.

[0051] It should be noted that when the base 10 is a single-layer structure, Figure 6 As shown, in some embodiments, the base 10 includes a third end surface 15, a fourth end surface 16, and a second outer peripheral surface 17. The third end surface 15 and the fourth end surface 16 are disposed opposite each other and connected to the first end surface 21. The second outer peripheral surface 17 is located between the third end surface 15 and the fourth end surface 16. The second outer peripheral surface 17 is provided with a countersunk hole 18 extending toward the center of the base 10. In this embodiment, when the base 10 is fixedly connected to the housing 210 of the power supply device 200 through secondary injection molding, the plastic body of the housing 210 can be embedded in the countersunk hole 18 of the base 10, ensuring a secure connection between the base 10 and the housing 210 and preventing the pole 100 from falling out of the housing 210.

[0052] like Figure 7 As shown, in some embodiments, when the base 10 is a single-layer structural member, the base 10 is a right cone, and the second outer peripheral surface 17 is provided with a countersunk hole 18 extending toward the center of the base 10. As described above, when the base 10 is fixedly connected to the housing 210 of the power supply device 200 through secondary injection molding, the right cone shape of the base 10 and the countersunk hole 18 on the second outer peripheral surface 17 of the base 10 can both improve the connection strength between the base 10 and the housing 210 of the power supply device 200, making it difficult for the terminal 10 to fall off the housing 210.

[0053] like Figure 1 and Figure 8 As shown, in some embodiments, the pole 100 is provided with a connection structure 30 , which is used to electrically connect to the energy storage module 220 of the power supply device 200 . The pole body 20 includes a metal column, and the connection structure 30 is also connected to the pole body 20 .

[0054] like Figure 1 and Figure 8 As shown, in some embodiments, the connection structure 30 includes a screw hole A extending from the base 10 toward the pole body 20, and the screw hole A is matched with the tab extending from the energy storage module 220. Correspondingly, the tab extending from the energy storage module 220 is a stud, and the stud is threadedly matched with the screw hole.

[0055] It should be noted that the connection structure 30 is not limited to the above-mentioned embodiment. For example, in some other embodiments, such as Figure 1 and Figure 9As shown, the connection structure 30 includes a stud B extending from the base 10. Correspondingly, the tab extending outward from the energy storage module 220 is provided with a screw hole, and the stud is threadedly engaged with the screw hole.

[0056] It should be noted that the connection structure 30 is not limited to the above-mentioned embodiment. For example, in some other embodiments, such as Figure 10 As shown, the connection structure 30 includes a tab C extending from the base 10 .

[0057] It should be noted that the connection structure 30 is not limited to the above-mentioned embodiment. For example, in some other embodiments, such as Figure 1 and Figure 11 As shown, the connection structure 30 includes a recess D extending from the pole body 20 , and the recess D is matched with the tab extending outward from the energy storage module 220 .

[0058] like Figure 12 As shown, in some embodiments, the pole 100 further includes an anti-detachment structure 40, which is provided on the first outer peripheral surface 23. The anti-detachment structure 40 is used to prevent the external wire 310 from falling off from the pole body 20. In this embodiment, by providing the anti-detachment structure 40 on the first outer peripheral surface 23 of the pole body 20 to prevent the external wire 310 from falling off from the pole body 20, the reliability of the connection between the pole 100 and the external wire 310 is improved.

[0059] like Figure 12 As shown, in some embodiments, the anti-drop structure 40 includes a boss provided on the first outer peripheral surface 23. When the external wire 310 is connected to the pole body 20, the boss abuts the external wire 310, preventing the external wire 310 from falling off from the pole body 20 along the direction from the first end surface 21 to the second end surface 22.

[0060] like Figure 12 As shown, in some embodiments, the boss is provided at the junction of the first outer peripheral surface 23 and the second end surface 22. Of course, the boss is not limited to being provided at this location, and the boss may also be provided at other locations on the first outer peripheral surface 23, as long as the boss can prevent the external wire 310 from falling off from the terminal body 20 along the direction from the first end surface 21 to the second end surface 22.

[0061] In some embodiments, the anti-slip structure 40 is continuously or discontinuously disposed around the first outer peripheral surface 23 .

[0062] It should be noted that the anti-slip structure 40 is not limited to a boss. For example, in some other embodiments, the anti-slip structure 40 includes a groove provided on the first outer peripheral surface 23. Correspondingly, the clamp of the external wire 310 is provided with a protrusion. When the clamp of the external wire 310 is clamped on the pole body 20, the protrusion is embedded in the groove, thereby preventing the clamp of the external wire 310 from loosening from the pole body 20.

[0063] like Figures 1 to 12 As shown, an embodiment of the present invention further proposes a power supply device 200, which includes a shell 210, an energy storage module 220 and the above-mentioned pole 100, wherein the energy storage module 220 is accommodated inside the shell 210, wherein the pole 100 is connected to the shell 210, and the pole 100 is electrically connected to the energy storage module 220.

[0064] The power supply device 200 proposed in this embodiment, because it adopts the above-mentioned pole 100 , has the advantage of preventing the external wire 310 from falling off from the pole body 20 , thereby improving the reliability of the connection between the pole 100 and the external wire 310 .

[0065] In some embodiments, the housing 210 is fixed to the base 10 of the pole 100 by secondary injection molding. Of course, the base 10 of the pole 100 and the housing 210 are not limited to being connected by secondary injection molding. The base 10 of the pole 100 and the housing 210 can also be connected by mechanical coupling, such as by threaded connection or fastening with fasteners.

[0066] In some embodiments, the energy storage module 220 includes at least one of a lithium battery, a sodium battery, a lead-acid battery, or a supercapacitor.

[0067] In some embodiments, the power supply device 200 includes a starting battery, and the power supply device 200 is used to connect to a vehicle via the pole 100 to supply power to the vehicle or start the ignition.

[0068] The structures, connection relationships, extended descriptions and beneficial effects of other components of the power supply device 200 proposed in this embodiment can refer to the above embodiments and will not be described in detail here.

[0069] like Figures 1 to 12 As shown, an embodiment of the present invention further proposes a power supply device 300, which includes an external wire 310 and the above-mentioned power supply device 200, wherein the external wire 310 includes a wire 320 and a connecting terminal 330 for connecting the wire 320, wherein the connecting terminal 330 has a connecting hole, and the connecting terminal 330 is sleeved on the pole body 20 through the connecting hole, or the connecting terminal 330 is a clamp, and the clamp is clamped on the pole body 20.

[0070] The power supply device 200 proposed in this embodiment, because it adopts the above-mentioned pole 100 , has the advantage of preventing the external wire 310 from falling off from the pole body 20 , thereby improving the reliability of the connection between the pole 100 and the external wire 310 .

[0071] like Figure 1As shown, in some embodiments, the clamp includes an arcuate portion 3301, a first extension portion 3302, a second extension portion 3303, and a fastening assembly 340. The arcuate portion 3301 includes a first end E1 and a second end E2. The first extension portion 3302 is connected to the first end E1, the second extension portion 3303 is connected to the second end E2, and the wire 320 is connected to the arcuate portion 3301. The arcuate portion 3301 is at least partially configured as a conductor. The fastening assembly 340 includes a bolt 3401 and a nut 3402. The bolt 3401 is inserted through the first extension portion 3302 and the second extension portion 3303. The nut 3402 is threadedly engaged with the bolt 3401. The nut 3402 has a loose position and a locked position. When the nut 3402 is in the loose position, the arcuate portion 3301 clamps the pole body 20. When the nut 3402 is in the locked position, the arcuate portion 3301 loosens the pole body 20.

[0072] Specifically, when the clamp needs to be installed on the pole 100, the operator rotates the nut 3402 to the loose position. At this point, the inner diameter of the arc portion 3301 is larger than the outer diameter of the pole body 20. The operator fits the arc portion 3301 over the pole body 20 and then rotates the nut 3402 to the locked position. The first extension 3302 and the second extension 3303 move toward each other, reducing the inner diameter of the arc portion 3301 to clamp the pole body 20, thus completing the installation of the clamp. When the clamp needs to be removed from the pole 100, the operator rotates the nut 3402 to the loose position. The inner diameter of the arc portion 3401 increases due to its own elastic force, and the operator can remove the clamp from the pole body 20.

[0073] It should be noted that the clamp is not limited to the above-mentioned embodiment. For example, in some other embodiments, the clamp can be set to two arc-shaped parts that are rotatably connected at one end, and the other ends of the two arc-shaped parts are locked or loosened by a fastening assembly. The specific embodiment can be determined according to actual design needs.

[0074] The structures, connection relationships, extended descriptions and beneficial effects of other components of the power supply device 300 proposed in this embodiment can refer to the above embodiments and will not be elaborated here.

[0075] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
