Technical Field

[0001] The present invention relates to capacitor technology, and in particular to a supercapacitor energy storage module. Background Art

[0002] The connection between capacitor modules and power modules in the existing technology mostly has the following problems: First, most of them adopt the layout method of PCB board + capacitor welding, which not only makes the plug-in assembly complicated and the PCB board warping and positioning inaccurate, but also has a high defect rate of the connection between the capacitor and the PCB board, and the resistance of the connection point is large, which inevitably leads to a certain amount of energy loss and insufficient resource utilization; second, if the layout method is unreasonable, it is easy to cause the PCB board space to be occupied, making it difficult to arrange and route components on the PCB board, resulting in an increase in the PCB board area, and thus an increase in the size of the controller.

[0003] When connecting its supercapacitor to other electronic components, it adopts plug-in connection, which is easy to disconnect or become loose during use, causing the supercapacitor to short-circuit or have poor contact, thus causing the equipment to malfunction. Summary of the Invention

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] Example 1

[0040] like Figures 1 to 15 As shown, the supercapacitor energy storage module of the present invention includes a base 1 and a capacitor body 2. The base 1 is provided with multiple docking seats 3, and the capacitor body 2 is provided with multiple docking parts 4 that cooperate with the docking seats 3. The docking parts 4 and the docking seats 3 form a docking assembly 5, which enables the capacitor body 2 to be installed on the base 1 and the single capacitor body 2 to be combined into a capacitor energy storage module 6.

[0041] The base 1 is provided with multiple docking seats 3, and the docking seats 3 are provided with symmetrically arranged mounting parts 7. A mounting hole 8 is provided in the middle of the mounting part 7. The docking seats 3 can be installed on the base 1 by bolts for easy disassembly and assembly. At the same time, the docking seats 3 can also be welded to the base 1 by welding.

[0042] A docking chamber 9 is formed in the middle of the docking seat 3 , and the docking member 4 with the conductive terminal 10 is inserted into the docking chamber 9 and contacts the internal contact terminal 11 to achieve electrical connection and limit the conductive terminal 10 at the same time.

[0043] A support protrusion 12 is located in the center of the docking chamber 9. This protrusion is used to limit the position of the conductive terminals 10. Symmetrically positioned contact terminals 11 are mounted on this protrusion, which is secured to the support protrusion 12 via conductive rods 13. A movable hole 15 is located in the center of this protrusion, which engages with a pressure rod 14. This movable hole 15 is located between the symmetrically positioned contact terminals 11, and a spring 16 is located within this movable hole 15.

[0044] The inner wall of the movable hole 15 is provided with a symmetrically arranged mounting groove 17, a sliding groove 18, and a rotationally symmetrical arcuate groove 19. The arcuate groove 19 connects the mounting groove 17 and the sliding groove 18, forming a 90° angle between the mounting groove 17 and the sliding groove 18. A guide ramp 20 is provided at the junction between the sliding groove 18 and the arcuate groove 19. This guide ramp 20 prevents the limit plate 21 from rotating when pressure is applied. When the limit plate 21 rotates a certain angle, the guide ramp 20 guides the mounting protrusion 22 into the sliding groove 18 when pressure is applied by the pressure rod 14.

[0045] A positioning groove 23 is provided at the upper end of the sliding groove 18. The arc angle of the arc groove 19 is also 90 degrees, so that after the mounting protrusion 22 is installed in the mounting groove 17, it is rotated 90 degrees to allow the mounting protrusion 22 to pass through the arc groove 19 from the mounting groove 17 to the arc groove 19. Then, under the elastic force of the spring 16, the mounting protrusion 22 is pushed into the positioning groove 23 to be limited.

[0046] A limiting plate 21 is disposed within the movable hole 15, and symmetrically disposed mounting protrusions 22 are provided on the limiting plate 21. The mounting protrusions 22 cooperate with the mounting groove 17 and the sliding groove 18. The mounting protrusions 22 are installed in the mounting groove 17, compressing the spring 16, which then passes through the arcuate groove 19 and places the mounting protrusions 22 in the positioning groove 23.

[0047] Symmetrical holes 24 are provided on the limiting plate 21 . When installing the limiting plate 21 , tweezers are placed in the holes 24 to clamp the limiting plate 21 , and then the limiting plate 21 is installed in the movable hole 15 .

[0048] When the mounting protrusion 22 is placed in the positioning groove 23, the spring 16 is in a compressed state. After the pressure rod 14 applies pressure to the limiting plate 21, the mounting protrusion 22 is kept from the positioning groove 23 and enters the sliding groove 18, thereby compressing the spring 16 to a certain distance. When the capacitor body 2 needs to be removed from the docking seat 3, it is only necessary to press the capacitor body 2 again, so that the pressure rod 14 on the docking member 4 applies pressure to the limiting plate 21, and the limiting plate 21 again applies pressure to the spring 16, thereby further compressing the spring 16.

[0049] Example 2

[0050] The contact terminal 11 is composed of a contact section 25, a mounting section 26, and a plurality of oblique sections 27 for connecting the contact section 25 and the mounting section 26. The contact section 25 contacts the pressure section 28. When the contact section 25 is pressed, the oblique section 27 is kept moving toward the mounting section 26.

[0051] Furthermore, a plurality of spherical protrusions 29 are provided on the contact section 25, and a spherical recess 30 is provided on the pressure section 28 to cooperate with the spherical protrusions 29, thereby increasing the contact area.

[0052] When the conductive terminal 10 is inserted into the docking chamber 9 along with the docking member 4, the conductive terminal 10 contacts the contact terminal 11, and the spherical protrusion 29 contacts the spherical recess 30. Furthermore, the conductive terminal 10 applies external pressure to the contact terminal 11, keeping the contact terminal 11 slightly deformed downward. It is only necessary to maintain contact and compression between the contact section 25 and the pressure section 28, and to ensure that the contact terminal 11 can continue to be pushed downward, so that the conductive terminal 10 can be unlocked and the docking member 4 can be separated from the docking seat 3.

[0053] The capacitor body 2 cooperates with the docking seat 3, and a docking piece 4 that cooperates with the docking seat 3 is provided at the lower end of the capacitor body 2. A symmetrically arranged conductive terminal 10 is provided in the middle of the docking piece 4. The conductive terminal 10 is inserted into the docking chamber 9 and contacts with the symmetrically arranged contact terminal 11 to achieve electrical connection.

[0054] A hinge rod 31 and a positioning rod 32 are provided within the docking chamber 9. A first through-hole 33 and a second through-hole 34 are provided on the docking seat 3. The hinge rod 31 is disposed within the first through-hole 33, and the positioning rod 32 is disposed within the second through-hole 34. A retaining member 35 is provided on the hinge rod 31 and hingedly connected to the hinge rod 31. The retaining member 35 has a notch 36 formed therein, and a limiting rod 37 is disposed within the notch 36. The limiting rod 37 is connected to the positioning rod 32 via a tension spring 38.

[0055] The docking member 4 is provided with a vertical slot 39 and a transverse slot 40, and the elastic section 41 on the conductive terminal 10 cooperates with the vertical slot 39, and the transverse section 42 cooperates with the transverse slot 40. The docking member 4 also has symmetrically arranged positioning extensions 43 for limiting the deformation direction of the elastic section 41.

[0056] Example 3

[0057] The retaining member 35 is composed of a limiting end 44 and a pulling end 45. The limiting end 44 is provided with a first inclined surface 46 and a second inclined surface 47. The first inclined surface 46 is located above the second inclined surface 47, and the limiting rod 37 is provided on the pulling end 45. The first inclined surface 46 is used to keep the pressure section 28 pushing the first inclined surface 46 when the conductive terminal 10 is inserted, causing the retaining member 35 to rotate, causing the limiting end 44 to rotate downward. Then, because the position of the retaining member 35 remains unchanged and only rotates, while the conductive terminal 10 moves, the conductive terminal 10 can continue to move downward, keeping the limiting end 44 in the limiting opening 48 and limiting it. Under the elastic force of the contact terminal 11 and the spring 16, the conductive terminal 10 generates a reverse force, pushing the conductive terminal 10 upward, while the conductive terminal 10 is limited by the retaining member 35 and remains fixed in the limited position.

[0058] After the conductive terminal 10 is inserted into the docking chamber 9, pressure is applied to the contact terminal 11 to keep the contact terminal 11 in contact with the conductive terminal 10. The conductive terminal 10 pushes the retaining member 35 to rotate on the hinge rod 31, so that the tension spring 38 is stretched, and the retaining member 35 limits the position of the conductive terminal 10.

[0059] The conductive terminal 10 is composed, from top to bottom, of a vertical section 49, a transverse section 42, a resilient section 41, an arcuate section 50, an inclined section 51, and a pressure-applying section 28. An arcuate opening 52 is formed in the middle of the arcuate section 50. When the retaining member 35 is within the arcuate opening 52, the retaining member 35 does not contact the lowest point of the inner wall of the arcuate opening 52.

[0060] The inclined section 51 is provided with a limiting opening 48, the lower end of which is provided with a limiting protrusion 53, which is provided with a guiding slope 54 and a limiting surface 55. The limiting end 44 is placed in the limiting opening 48. A blocking protrusion 56 is formed at the connection between the inclined section 51 and the arc section 50.

[0061] A through hole 57 for accommodating the conductive rod 13 is provided in the middle of the docking seat 3 .

[0062] The docking member 4 is also provided with a pressure rod 14, which is positioned between the symmetrically arranged conductive terminals 10, forming a limiting gap 58 between the pressure rod 14 and the conductive terminals 10. When the capacitor body 2 is installed and pulled upward by an external force, the limiting protrusion 53 can drive the limiting end 44 to move upward, causing the retaining member 35 to rotate upward. However, since the retaining member 35 is hinged within the docking chamber 9 by the hinge rod 31, the retaining member 35 remains stationary. The conductive terminals 10 are then pushed by the retaining member 35 toward the pressure rod 14, causing the pressure rod 14 to block the lower ends of the conductive terminals 10, preventing the limiting end 44 of the retaining member 35 from rotating to a horizontal position, thereby confining the docking member 4 within the docking seat 3.

[0063] like Figure 15 As shown, at this time, the conductive terminal 10 has been in contact with the contact terminal 11, and the retaining member 35 has limited the conductive terminal 10 so that it cannot be pulled out.

[0064] When the capacitor body 2 needs to be replaced, the capacitor body 2 only needs to be pressed toward the docking seat 3. The pressure rod 14 compresses the spring 16, causing the inclined section 51 to push the limiting end 44 on the retaining member 35, causing the limiting end 44 to enter the arc-shaped opening 52. Under the tension of the tension spring 38, the limiting end 44 on the retaining member 35 is kept horizontal, that is, the first inclined surface 46 remains horizontal. Then, the capacitor body 2 is pulled, and the conductive terminal 10 is moved upward together. The arc-shaped opening 52 drives the limiting end 44 of the retaining member 35 to rotate upward, compressing the tension spring 38. The retaining member 35 no longer restricts the conductive terminal 10, and the capacitor body 2 can be removed for replacement or maintenance.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
