Description

Technical Field

[0001] The utility model relates to a self-generating device, and more specifically to a self-generating module spring sheet transmission connection structure and a self-generating switch. Background Art

[0002] The self-generating module is also called the micro-kinetic energy press-to-generate module. It uses the principle of electromagnetic induction to change the direction of magnetic flux by pressing, etc., to generate an electromotive force in the coil, and then form an induced current in the closed loop. It is currently widely used in some wireless control switches or devices, such as wireless doorbell buttons, wireless controlled light switches, remote controls and wireless keyboards, etc. It generates current by pressing to send control signals, and no longer needs to be powered by batteries.

[0003] The existing self-generating module mainly consists of two parts: a coil and a magnetic circuit. The magnetic circuit part is usually composed of a permanent magnet, a magnetic guide frame and a switching lever. The coil is wound on the magnetic circuit. The switching lever changes the magnetic flux direction of the magnetic circuit, so that an induced current is generated in the coil. During the switching process of the magnetic flux direction of the magnetic circuit, the switching speed directly affects the power generation efficiency and current intensity. For this reason, the existing self-generating modules mostly use a spring design on the lever, which uses the deformation of the spring during the pressing process to store energy, so that when the lever reaches the critical point of switching, the elastic force of the spring can be used to quickly switch the lever.

[0004] In some self-generating devices, the shrapnel is often not directly triggered, but indirectly controlled by the transmission member. At present, the cooperation between the transmission member and the shrapnel is mainly to set a shrapnel hole on the transmission member, and the free end of the shrapnel of the self-generating module extends into the shrapnel hole. Due to the manufacturing process limitations of the shrapnel hole, it is difficult to punch a small hole in a 2mm thick transmission member, which can easily cause the punching needle to break. Therefore, the height dimension of the existing shrapnel hole (the dimension of the shrapnel in the active direction) is often greater than 1mm, and the thickness of the shrapnel is relatively thin, generally only 0.2mm, which leads to more empty strokes during the transmission process, and a larger pressing key stroke is required, which affects the operating feel. If you want to form a shrapnel hole with a smaller height dimension, you can usually only use a transmission member with a thinner thickness, but the rigidity of the thinner transmission member is reduced, and its pressing deformation will affect the pressing stroke, and the above problem cannot be solved from the root.

[0005] In response to the above problems, Chinese patent application number CN202210897034.X discloses "a self-generating module double spring trigger mechanism and a self-generating key switch", in which a spring hole is provided on the transmission member, and the free end of the spring extends into the spring hole. The spring includes an upper spring and a lower spring arranged relatively to each other, and there is a gap between the upper spring and the lower spring in a free state. The upper spring is used to bend and store energy during the pressing process of the transmission member, and the lower spring is used to bend and store energy during the rebound process of the transmission member. This can reduce the pressing and rebound stroke of the spring, improve the triggering stability of the self-generating module, and improve the user experience of the self-generating product; and the size of the spring hole that cooperates with the double spring can be designed to be larger, which facilitates the production of the spring hole. The above patent application solves the problem of the matching stroke between the transmission member and the spring through the double spring design, but it requires the use of two springs to work together, which increases the number of parts and the product manufacturing cost. Summary of the invention

[0006] 1. Technical problems to be solved by the utility model

[0007] The purpose of the utility model is to overcome the shortcomings of the prior art that there is a large idle stroke between the spring and the spring hole due to the limitation of the spring hole punching process, and to provide a self-generating module spring transmission connection structure and a self-generating switch. By adopting the technical solution of the utility model, the spring hole is formed by bending the punching hole on the bending part at an angle α, so that the spring in the spring hole has an effective activity space d 2 Smaller than the width of the punched hole d 1 , so that a shrapnel hole with a smaller active space can be formed by a larger punching hole, which effectively solves the problem of a large empty travel between a single shrapnel and the shrapnel hole, resulting in a large key stroke and poor operating feel. It has the advantages of simple manufacturing process, adjustable and convenient active space, and low manufacturing cost. The matching clearance between the shrapnel and the shrapnel hole can be adjusted according to the requirements of different products, greatly improving the operating stability and operating texture of the product.

[0045] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0046] [Example 1]

[0047] Combination Figures 1 to 7 As shown, a spring-type transmission connection structure of a self-generating module of the present embodiment comprises a spring-type spring 1-1 arranged on the self-generating module 1 and a transmission member 2 for driving the spring-type spring 1-1 to bounce up and down, the transmission member 2 is used to transmit actions such as pressing, and apply such actions to the spring-type spring 1-1 to drive the self-generating module 1 to switch the direction of the magnetic circuit, the self-generating module 1 is provided with a magnetic lever 1-2, the magnetic lever 1-2 can make a lever movement in the self-generating module 1 to change the direction of the magnetic circuit, the spring-type spring 1-1 is installed at the end of the magnetic lever 1-2; a bending portion 2-1 is provided on the transmission member 2, the bending portion 2-1 has a spring-type spring hole 2-2, the free end of the spring-type spring 1-1 extends into the spring-type spring hole 2-2, the action of the transmission member 2 can be transmitted to the magnetic lever 1-2 through the spring-type spring 1-1, and the magnetic lever 1-2 switches the direction of the magnetic circuit to form an induced current. In this embodiment, the spring hole 2-2 is formed by bending the punched hole 2-2' on the bending portion 2-1 at an angle α. After bending, the effective activity space d of the spring 1-1 in the spring hole 2-2 is 2 Smaller than the width d of the punched hole 2-2' 1 When the bending portion 2-1 with the punched hole 2-2' is bent, the effective activity space d in the spring hole 2-2 is 2 The punching hole 2-2' can be formed by punching equipment, and the spring hole 2-2 is formed by bending the punching hole 2-2', which has a simple manufacturing process and lower manufacturing cost.

[0048] Specifically, the bending portion 2-1 can change the effective activity space d of the spring hole 2-2 by the bending position and / or the bending angle. 2That is, the position of the bending portion 2-1 can change the effective activity space of the spring hole 2-2 after the bending, and the bending angle can also change the effective activity space of the spring hole 2-2 after the bending. In this way, the matching clearance between the spring 1-1 and the spring hole 2-2 can be flexibly adjusted to meet the matching requirements of different products. The pressing operation of the self-generating module can be adjusted to the best state with a simple structure, which has very good practical value.

[0049] like Figure 4 As shown, in this embodiment, the bending line of the bending portion 2-1 is located in the area where the punching hole 2-2' is located, and the outer surface of the transmission member 2 is used as the lower hole wall 2-2b of the spring hole 2-2 to limit the spring 1-1, so that a larger punching hole 2-2' can be used to form a spring hole 2-2 of a suitable size, which solves the problem that a small-sized punching hole is difficult to form and facilitates the production of the spring hole 2-2. Generally speaking, the transmission member 2 is a sheet metal part with a thickness of 2mm, and the thickness of the spring 1-1 is 0.2mm. If the spring 1-1 is to have a smaller activity space in the spring hole 2-2, it is necessary to punch a small hole slightly larger than 0.2mm at the bending portion 2-1. However, the strength of the small-sized punching needle in the prior art cannot meet the requirements, and it is easy to break when punching a hole in a 2mm thick metal plate. Generally, it is the limit to punch a small hole with a width of 1mm. Therefore, it is very difficult to punch a small hole that meets the requirements. By adopting the technical solution of this embodiment, a punching hole 2-2' with a width of more than 1 mm can be punched out first, and then the bending position is made within the punching hole 2-2' area during the bending process, so that the hole wall on one side of the punching hole 2-2' is bent to the upper part, while the hole wall on the opposite side is not bent, forming Figure 5 In the state shown, the distance between the upper hole wall 2-2a and the outer surface of the transmission member 2 is the effective activity space d of the spring 1-1 in the spring hole 2-2. 2 , the effective activity space d 2 will be smaller than the width d of the punched hole 2-2' 1 In this way, the relatively large punching hole 2-2' which is convenient to form can be used to produce a relatively small spring hole 2-2. In addition, the above-mentioned effective activity space d can be adjusted by changing the position of the bending line. 2 .

[0050] like Figure 5 As shown, when the bending angle α of the bending portion 2-1 is equal to 90°, the far end hole wall of the punched hole 2-2' is used as the upper hole wall 2-2a of the spring hole 2-2 to limit the spring 1-1. 2 This can be achieved by changing the bending angle α of the bending portion 2-1, such as Figure 6 and Figure 7As shown, when the bending angle α of the bending portion 2-1 is less than or greater than 90°, the upper hole wall 2-2a is inclined, and the lower edge of the far end hole wall of the bent punching hole 2-2' serves as the effective activity space d of the spring sheet 1-1 through the spring sheet hole 2-2 2 The upper limit of the part can further reduce the effective activity space d 2 , and the gap is easy to adjust.

[0051] [Example 2]

[0052] The basic structure and working principle of the self-generating module spring-type transmission connection structure of this embodiment are the same as those of the first embodiment, except that:

[0053] like Figure 8 and Fig. 9 As shown, in this embodiment, when the bending line of the bending portion 2-1 is located outside the area where the punching hole 2-2' is located, the bending angle α of the bending portion 2-1 is less than or greater than 90°, and the outer edges of the upper and lower end hole walls of the punching hole 2-2' after bending serve as the effective activity space d of the spring sheet 1-1 by the spring sheet hole 2-2 2 At this time, the punching hole 2-2' is bent along with the bending portion 2-1 as a whole, but because the bending portion 2-1 itself has a certain wall thickness, when the bending angle α of the bending portion 2-1 is not equal to 90°, the upper hole wall 2-2a and the lower hole wall 2-2b of the punching hole 2-2' are in an inclined state, and the lower edge of the upper hole wall 2-2a and the upper edge of the lower hole wall 2-2b constitute the effective activity space d of the spring 1-1. 2 At this time, the effective activity space d 2 It is also smaller than the width d of the punched hole 2-2' 1 Moreover, by changing the bending angle α, the above-mentioned effective activity space d can be adjusted. 2 The size of the spring piece 1-1 ensures that it fits in the appropriate effective activity space d 2 Inside.

[0054] [Example 3]

[0055] The basic structure and working principle of the self-generating module spring-type transmission connection structure of this embodiment are the same as those of the first embodiment, except that:

[0056] like Figures 10 to 12As shown, in this embodiment, a convex point 2-2c is also stamped on one side of the transmission member 2 near the punching hole 2-2', and the convex point 2-2c is located on the side of the punching hole 2-2' that is not bent, and the convex point 2-2c is used as the lower limit portion of the spring hole 2-2. After the bending portion 2-1 is bent along the bending line, the far end hole wall of the punching hole 2-2' is used as the upper hole wall 2-2a of the spring hole 2-2 to limit the spring 1-1, and the convex point 2-2c on the outer surface of the transmission member 2 is used as the spring hole 2-2 to limit the lower end of the spring 1-1, so that the above-mentioned effective activity space d can be further reduced. 2 The size of the spring hole 2-2 is formed by using a larger punching hole 2-2' to form a spring hole 2-2 of appropriate size.

[0057] Fig.12 The figure shows the case where the bending angle α is equal to 90°. Similarly, the bending angle α can be further changed to limit the range of movement of the spring 1-1 by using the lower edge of the upper hole wall 2-2a and the protrusion 2-2c of the punching hole 2-2'.

[0058] [Example 4]

[0059] Reference Figures 13 to 16 As shown, the present embodiment relates to a self-generating switch, which includes a self-generating module 1, a transmission member 2, an elastic member 3, a base 4, a key panel 5 and a circuit board 8. The self-generating module 1 and the circuit board 8 are fixedly installed in the base 4, the self-generating module 1 is electrically connected to the circuit board 8, the transmission member 2 is movably arranged in the base 4 and cooperates with the elastic member 3, the key panel 5 is movably installed on the base 4, and is directly or indirectly connected to the transmission member 2, and the self-generating module 1 and the transmission member 2 are connected by the self-generating module spring-type transmission connection structure of the above-mentioned embodiment 1 or embodiment 2 or embodiment 3, so that the self-generating switch has a smaller pressing stroke and better pressing rebound feedback, which further improves the use texture of the self-generating switch.

[0060] The above-mentioned self-generating module 1 has an induction coil and a magnetic circuit structure that can be switched by a magnetic lever 1-2. The induction coil is connected to the circuit board 8. The spring 1-1 is installed at one end of the magnetic lever 1-2. When the key panel 5 is pressed, the key panel 5 drives the transmission member 2 to be pressed. At this time, the elastic member 3 is compressed, and at the same time drives the spring 1-1 to deform downward. When the elastic force of the spring 1-1 reaches the critical point of switching of the magnetic lever 1-2, the spring 1-1 can drive the magnetic lever 1-2 to quickly switch the magnetic circuit, thereby generating an induced current in the induction coil, and then the self-generating switch makes a corresponding response action after the key panel 5 is pressed. As for the specific structure of the self-generating module 1 and the circuit principle of the circuit board 8, they are similar to the prior art, so they will not be described in detail here.

[0061] In the self-generating switch of this embodiment, the elastic member 3 is a torsion spring, which is arranged on one side of the transmission member 2 close to the self-generating module 1 (such as Figure 1 and Fig.15 As shown in the figure, the internal structure of the self-generating switch is more compact, which is convenient for the flat design of the self-generating switch. In addition, a waterproof soft cover 6 is provided on the self-generating module 1 and the circuit board 8, and the waterproof soft cover 6 is fixed by an intermediate pressure cover 7 installed on the base 4. The waterproof soft cover 6 can be made of soft silicone, and the intermediate pressure cover 7 is used to press and fix the waterproof soft cover 6 to play a waterproof role.

[0062] The above-mentioned key panels 5 are provided with at least two, each of which has a pressing column. After pressing any key panel 5, it can act on the transmission member 2 through the pressing column to complete the self-discharge of the pressing action. Of course, the circuit board 8 is also provided with a contact switch corresponding to the corresponding key panel 5. When a key panel 5 is pressed, the corresponding contact switch is pressed at the same time, and then a signal of pressing the corresponding key panel 5 can be sent, so that each key panel 5 can be controlled as an independent function.

[0063] The utility model discloses a self-generating module spring transmission connection structure and a self-generating switch. The spring hole on the transmission member is formed by bending the punching hole on the bending part at an angle α, so that the spring has an effective activity space d in the spring hole. 2 Smaller than the width of the punched hole d 1 , so that a shrapnel hole with a smaller active space can be formed with a larger punching hole, effectively solving the problem of a large empty stroke between a single shrapnel and the shrapnel hole, which leads to a large key stroke and poor operating feel. It has the advantages of simple manufacturing process, adjustable and convenient active space, and low manufacturing cost. The matching clearance between the shrapnel and the shrapnel hole can be adjusted according to the requirements of different products, greatly improving the operational stability and operating texture of the product. Applied to the self-generating switch, the self-generating switch has a smaller pressing stroke and better pressing rebound feedback, further improving the use texture of the self-generating switch.

[0064] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
