Description

Technical Field

[0002] Portable mechanical energy storage based on measuring springs or mainsprings is widely used as a green energy storage form in low-power devices such as toys and mechanical watches. To increase energy storage capacity, multiple measuring springs are typically connected in series or parallel. Currently, commonly used parallel measuring spring designs are usually based on a dual-mainspring barrel parallel design, such as the patent with publication number CN209118078U. There are also multi-mainspring barrel parallel designs, such as the axial parallel design based on spatial arrangement in patent CN101445202B, and the parallel design based on coplanar arrangement in patent CN110985598B. However, these parallel designs do not propose a complete energy storage system design, nor do they consider the energy storage density.

Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The objectives and effects of the present invention will become clearer as a result. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] like Figures 1-4 As shown, a modular parallel tape measure spring energy storage battery includes multiple energy storage unit cells A component 1 and B component cells 2, which are alternately assembled by connecting blocks in the outer casing. The modular design makes the overall device more flexible and easier to assemble and disassemble.

[0028] The two types of energy storage unit modules are distinguished by the number and arrangement of energy storage elements. Energy storage unit module A 1 includes: a lower housing 1-1, one input gear 1-2, four input gears 1-3, an upper housing 1-4, one output gear 1-5, four output gears 1-6, an energy storage element 1-7, and a ratchet and pawl mechanism 1-8. Energy storage unit module B 2 includes: a lower housing 2-1, one input gear 2-2, six input gears 2-3, an upper housing 2-4, one output gear 2-5, six output gears 2-6, an energy storage element 2-7, and a ratchet and pawl mechanism 2-8.

[0029] Five through holes are formed on the lower outer shell 1-1 according to the hexagonal close-packed structure of a two-dimensional crystal. Five through holes are formed on the upper outer shell 1-4, forming five pairs of through holes. Five energy storage units 1-7 are arranged between the lower outer shell 1-1 and the upper outer shell 1-4, each coaxial with one of the five through holes. The output shaft of each energy storage unit 1-7 passes through the through hole of the upper outer shell 1-4, and the input shaft passes through the corresponding through hole of the lower outer shell 1-1.

[0030] On the input shaft of the energy storage unit 1-7, which passes through the central through hole of the lower housing 1-1, an A ratchet and pawl mechanism 1-8 and an A input transmission gear 1-2 are fixedly installed in sequence. The A ratchet and pawl mechanism 1-8 is used to realize the unidirectional movement of the gear. At the four through holes on the outer periphery, an A input gear 1-3 is fixedly installed on the input shaft of the energy storage unit 1-7, and the A input gear 1-3 meshes with the A input transmission gear 1-2.

[0031] An A output transmission gear 1-5 is fixedly installed on the output shaft of the A energy storage unit 1-7, which passes through the central through hole of the upper outer shell 1-4; an A output gear 1-6 is fixedly installed on the output shaft of the A energy storage unit 1-7 at each of the four through holes on the outer periphery; the A output gears 1-6 mesh with the A output transmission gears 1-5, and the four A output gears 1-6 are connected in parallel with the A output transmission gears 1-5. This method allows energy to be concentrated and output from the A output transmission gears 1-5, while simultaneously completing the energy collection.

[0032] like Figure 5 , Figure 6 As shown, a threaded hole 1-1-1 is provided on the non-jointing edge of the lower outer shell 1-1 (as shown). Figure 4As shown, two threaded holes 1-1-1 are respectively opened in the middle position of the lower outer shell 1-1 near the upper and lower sides), and a pin hole 1-1-2 is opened on the splicing edge (as shown). Figure 4 As shown, four pin holes 1-1-2 are respectively opened at the four corners of the lower outer shell 1-1 (A). Correspondingly, threaded hole 1-4-1 is opened on the non-joining edge of the upper outer shell 1-4 (A), and pin hole 1-4-2 is opened on the joining edge. Threaded hole 2-1-1 is opened on the non-joining edge of the lower outer shell 2-1 (B), and pin hole 2-1-2 is opened on the joining edge; threaded hole 2-4-1 is opened on the non-joining edge of the upper outer shell 2-4 (B), and pin hole 2-4-2 is opened on the joining edge.

[0033] The assembly between the two energy storage unit modules is achieved through pin holes in their contact portions. For example, for energy storage unit module A 1 and energy storage unit module B 2, taking the upper shell as an example, the two sides of the upper shell 1-4 of A and the upper shell 2-4 of B are accurately matched through pin holes 1-4-2 and 2-4-2, and then connected through the second AB shell connecting block 3-2 and fixed with pins; similarly, the two sides of the lower shell 1-1 of A and the lower shell 2-1 of B are accurately matched through pin holes 1-1-2 and 2-1-2, and then connected through the first AB shell connecting block 3-1 and fixed with pins.

[0034] Each energy storage unit is completely independent, and all energy storage units have the same structure. Taking energy storage unit A (units 1-7) as an example, as follows: Figure 7 , Figure 8 As shown, energy storage unit A 1-7 includes: a housing 1-7-1, a measuring spring 1-7-2, a unit shaft 1-7-3, and a base 1-7-4. The unit shaft 1-7-3, measuring spring 1-7-2, and housing 1-7-1 are arranged coaxially from the inside out. The bottom of housing 1-7-1 is open and sealed by the base 1-7-4. The output shaft of energy storage unit A 1-7 is coaxially arranged at the top center of housing 1-7-1, and the input shaft of energy storage unit A 1-7 is coaxially arranged at the bottom center of base 1-7-4. Furthermore, each energy storage unit may include multiple measuring springs 1-7-2 connected in series inside.

[0035] Furthermore, the ratchet and pawl mechanism 1-8 includes a ratchet and a pawl. The ratchet is installed in the through hole at the center of the lower housing 1-1 of A, and the pawl is installed in the ratchet to prevent the ratchet from moving in the opposite direction to the preset direction (i.e., the restricted direction) so as to achieve unidirectional intermittent motion, thereby preventing the automatic reverse rotation and energy release when the measuring tape spring 1-7-2 is wound up.

[0036] like Figure 9As shown, energy storage unit cell A component 1 and energy storage unit cell B component 2 are arranged alternately in the hexagonal close-packed structure [2 -1 -1 0] direction (i.e., ABAB…AB) to achieve the densest arrangement in the [2 -1 -1 0] direction and achieve the highest space utilization rate; in the hexagonal close-packed structure [-1 0 1 0] direction, they can be arranged alternately or repeatedly (AA…AA or BB…BB) to achieve the densest arrangement in the [-1 0 1 0] direction and achieve the highest space utilization rate.

[0037] In practical applications, the bottom drive gear (i.e., the input transmission gear, referring to input transmission gear A 1-2 and / or input transmission gear B 2-2) drives the input gear (input gear A 1-3 and / or input gear B 2-3) to drive the input shafts of multiple energy storage units, causing the measuring tape spring 1-7-2 to tighten and drive the outer casing 1-7-1 to rotate. Finally, the outer casings 1-7-1 of multiple energy storage units achieve a parallel effect by transmitting power through the same output transmission gear (output transmission gear A 1-5 and / or output transmission gear B 2-5).

[0038] At this point, there are two output options available.

[0039] The first method is to directly connect the mechanical load for output through the output transmission gears (including A output transmission gears 1-5 and B output transmission gears 2-5).

[0040] The second method involves connecting to a specific circuit output, which controls the rotation speed in reverse. Specifically, this is achieved by connecting a speed-regulating generator module via an output transmission gear.

[0041] like Figure 10 As shown, the speed-regulating power generation module 4, connected to the energy storage unit A component 1, includes: a generator 4-1, a control chip 4-2, a drive chip 4-3, a step-down circuit 4-4, an energy storage circuit 4-5, a step-up circuit 4-6, and an output section 4-7. The generator 4-1 of the speed-regulating power generation module 4 is mechanically connected to the A output transmission gear 1-5, that is, the A output transmission gear 1-5 drives the generator 4-1 to rotate, thereby completing the conversion of mechanical energy into electrical energy.

[0042] The current output terminal of generator 4-1 is connected to the current input terminal of step-down circuit 4-4. The speed output terminal of generator 4-1 is connected to the input terminal of control chip 4-2. The output terminal of control chip 4-2 is connected to the input terminal of drive chip 4-3. The output terminal of drive chip 4-3 is connected to the signal input terminal of step-down circuit 4-4. The current output terminal of step-down circuit 4-4 is connected to the input terminal of energy storage circuit 4-5. The output terminal of energy storage circuit 4-5 is connected to the input terminal of boost circuit 4-6. The output terminal of boost circuit 4-6 is connected to the input terminal of output section 4-7.

[0043] The overall structure of the speed-regulating power generation module 26, connected to the energy storage unit B component 2, is the same as or similar to that of the speed-regulating power generation module 14, including: generator 26-1, control chip 26-2, drive chip 26-3, step-down circuit 26-4, energy storage circuit 26-5, step-up circuit 26-6, and output section 26-7. Generator 26-1 is mechanically connected to the B output transmission gear 2-5, meaning the B output transmission gear 2-5 drives generator 26-1 to rotate, thus completing the conversion of mechanical energy into electrical energy. Adjustments can be made according to actual needs to adapt the circuit to specific conditions.

[0044] The external energy storage coordination circuit 5 of the two types of speed-regulating power generation modules is connected to the energy storage circuit 4-5 of the speed-regulating power generation module 1 and the energy storage circuit 6-5 of the speed-regulating power generation module 2, respectively, to complete the energy integration and adjustment between the two types of speed-regulating power generation modules.

[0045] After the output transmission gear 1-5 is driven to rotate by the measuring tape spring 1-7-2, thereby driving the generator 4-1 to rotate, the control chip 4-2 can read the rotational speed of the generator 4-1 and compare it with the program setting value inside the control chip 4-2. The duty cycle D is obtained through a PID algorithm, and the PWM driver chip 4-3 is driven by the control chip 4-2 itself. The driver chip 4-3 then drives the step-down circuit 4-4, adjusting the circuit impedance. This impedance adjustment also causes a change in the current flowing through the generator 4-1, resulting in a change in the electromagnetic resistance experienced by the generator 4-1. By adjusting the electromagnetic resistance, the rotation of the measuring tape spring 1-7-2 is made uniform.

[0046] Simultaneously, the current generated by generator 4-1 flows through buck circuit 4-4 and then into energy storage circuit 4-5, completing the storage of electrical energy. Boost circuit 4-6 then boosts the voltage of energy storage circuit 4-5, enabling the driving of equipment requiring higher voltage and achieving stable voltage output. It should be noted that control chip 4-2 can select to collect the rotational speed of generator 4-1, the rotational speed of output transmission gear 1-5, or the rotational speed of measuring spring 1-7-2, as long as stable acquisition of the overall device rotational speed is achieved. Specific settings for each component and parameter are determined according to actual conditions. Similarly, the components and parameters of drive chip 4-3, buck circuit 4-4, energy storage circuit 4-5, boost circuit 4-6, and energy storage coordination circuit 5 are also set according to actual conditions.

[0047] It will be understood by those skilled in the art that the above descriptions are merely preferred examples of the invention and are not intended to limit the invention. Although the invention has been described in detail with reference to the foregoing examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of the invention should be included within the scope of protection of the invention.
