By setting a concentric first conductive ring and a second conductive ring on the circuit board, and fixing a conductive spring on the connecting shaft of the button, the disconnection of the conductive connection and reset movement when the player presses the button is realized. At the same time, through the design of the locking plate and locking head, it can continue to maintain the downward state after the button is pressed, prompting the player that the button has been pressed.
The switching effect can be achieved without purchasing external switching components, which reduces production costs, and reduces the probability of accidentally touching through clear key status prompts, improving the experience of using the toy.

[0001] The utility model relates to the technical field of toy switch structures, and particularly to a key switch structure of an electronic toy. Background Art
[0002] Electronic toys are often provided with a key switch structure for starting and stopping corresponding functions of the toys. At present, most toys on the market adopt a switch element arranged on a circuit board, and the switch element is exposed on the toy surface through a key housing. A player can press the key to activate the switch element, and when the key is not stressed, it can be reset and moved under the drive of a reset spring. Although the switch element has the advantages of easy acquisition and stable function, the purchased switch element has a certain loss rate, and its price is higher than that of a conductive metal sheet, so the production cost cannot be further reduced. At the same time, the key switch structure of the existing electronic toy often cannot prompt the player of the touch state of the key, which is easy to cause accidental touch and lead to a poor use experience of the toy. In view of this, it is necessary to provide a key switch structure of an electronic toy to at least overcome or alleviate the above defects in the prior art. Summary of the Utility Model

When the locking head moves to be separated from the connecting block, the locking plate can be elastically reset to press the connecting block through the locking head.
[0008] Preferably, the conductive spring is in the shape of a funnel with one end extending outwards. The extended section of the conductive spring is fixed on the connecting shaft, and the second end is arranged on the extended section. The second end can be in contact with or separated from the second conductive ring as the connecting shaft moves.
[0009] Preferably, the connecting block is in a triangular prism structure, and the tip of the triangular prism structure faces the bottom of the first cavity or the second cavity.
[0010] Preferably, the first cavity is a V-shaped cavity, which is adapted to the connecting block, and one inclined surface of the V-shaped cavity is movably abutted against the connecting block.

The connection chamber is provided with a first opening for the key to expose on the first housing and a second opening for slidingly matching with the T-shaped head of the key.
[0014] Preferably, at least three mounting holes are further arranged on the first housing. Each mounting hole is used for fixing the conductive plug of the electronic toy, and the conductive plug is electrically connected to the positive terminal, the negative terminal and the load terminal of the circuit board through a wire.
[0015] Preferably, a sliding groove is arranged at the position of the third housing corresponding to the locking plate, and the locking plate is movably connected in the sliding groove.
[0016] Preferably, a plurality of sliding holes are respectively arranged in the third housing corresponding to the plurality of connection holes. Each sliding hole is movably connected with a connecting shaft in an insertable manner.

[0034] Please refer to Figure 1-8 , this embodiment provides a key switch structure of an electronic toy, which includes a housing 100, four keys 200 and a locking plate 300 that are respectively movably installed in the housing 100 in an elastically resetable manner through elastic members (such as springs, etc.), and a circuit board 400 fixed in the housing 100. Obviously, in other embodiments of the present utility model, the number of keys 200 can be correspondingly adjusted to two, three or more than five according to the design requirements of the electronic toy.
[0035] The housing 100 includes a first housing 110, a second housing 120 and a third housing 130. The first housing 110 and the second housing 120 are fixed and an installation cavity 101 is formed inside them. The third housing 130 is located in the installation cavity 101 and is fixed to the first housing 110. Among them, the circuit board 400 is fixed between the first housing 110 and the third housing 130, and the keys 200 and the locking plate 300 are movably installed between them in an elastically resetable manner.
[0036] A plurality of connection chambers 111 are respectively arranged in the first housing 110 corresponding to the plurality of keys 200. In this embodiment, a first opening 112 for the key 200 to expose on the first housing 110 and a second opening 113 for slidably mating with the T-shaped head of the key 200 are formed on the connection chamber 111. A corresponding key 200 is movably connected in the second opening 113, which is used to limit the key 200 to move only along the extension direction of the second opening 113. It can be understood that at least three mounting holes 114 (the number of mounting holes 114 is three in this embodiment) are also arranged on the first housing 110. Each mounting hole 114 is used to fix the conductive plug of the electronic toy (not shown in the figure). The conductive plug is electrically connected to the positive terminal, negative terminal and load terminal of the circuit board 400 through wires, so that the circuit board 400 can be connected to an external power supply and load (such as a fan, etc.) through the conductive plug, and then an electric circuit can be electrically connected.
[0037] A plurality of sliding holes 131 are respectively arranged in the third housing 130 corresponding to the plurality of keys 200. The sliding holes 131 have the same extension direction as the second opening 113. A corresponding key 200 is movably connected in the sliding hole 131 in an insertable manner, which is used to further limit the key 200 to move only along the extension direction of the sliding hole 131 (the second opening 113). Thus, even when the player presses the key 200 in an unconventional manner, the key 200 can still move in a direction perpendicular to the third housing 130 under the limitation of the second opening 113 and the sliding hole 131. In other embodiments of the present invention, the second opening 113 may not be provided on the housing 100. At this time, the key 200 may not be provided with a structure that movably cooperates with the second opening 113 correspondingly.
[0038] A chute 132 is also arranged on the third housing 130 at a position corresponding to the locking plate 300. The locking plate 300 is movably connected in the chute 132, which is used to limit the locking plate 300 to move only along the extension direction of the chute 132.
[0039] The key 200 protrudes out of the first housing 110 through the first opening 112. In this embodiment, the key 200 includes a fixed connecting shaft 210, a connecting block 220 and a T-shaped head 230. Among them, the connecting shaft 210 passes through the circuit board 400 and is movably connected in the sliding hole 131 in an insertable manner. A conductive spring 240 is fixed on the connecting shaft 210. The connecting shaft 210 is in contact connection with the circuit board 400 through the conductive spring 240. When the key 200 is pressed and moves downward, the connecting shaft 210 moves into the sliding hole 131. At this time, the connecting shaft 210 drives the conductive spring 240 to deform and store energy, which is used to enable the key 200 to move under the drive of the conductive spring 240 when not under the pressing force, so that the key 200 has the ability to automatically move and reset.
[0040] The connecting block 220 and the T-shaped head 230 are oppositely arranged on both sides of the button 200. Among them, the connecting block 220 and the locking plate 300 are movably in contact and cooperate, and are used to move along with the button 200 when the button 200 moves to push the locking plate 300 to move. The T-shaped head 230 is correspondingly movably clamped in the second opening 113 and is used to move in the second opening 113 along with the button 200 when the button 200 moves. Obviously, in other embodiments of the present invention, if the second opening 113 is not provided on the first housing 110, the button 200 may correspondingly not be provided with the T-shaped head 230.
[0041] A first concave cavity 310 and at least one second concave cavity 320 are arranged at intervals on the locking plate 300. The sum of the number of the first concave cavity 310 and the second concave cavity 320 is equal to the number of the buttons 200 (that is, equal to the number of the connecting blocks 220), and the first concave cavity 310 and the second concave cavity 320 are connected to the connecting blocks 220 in one-to-one correspondence.
[0042] It should be noted that the connecting block 220 is a triangular prism structure, and the tip of the triangular prism structure is arranged towards the bottom of the cavity of the locking plate 300. The first concave cavity 310 is a V-shaped cavity, which is adapted to the connecting block 220, and one inclined surface of the V-shaped cavity is movably in contact and cooperates with the connecting block 220. When the connecting block 220 moves along with the button 200, the connecting block 220 moves on the inclined surface of the first concave cavity 310, and can push the locking plate 300 to move in the direction of compressing the elastic member to store energy. At this time, the plurality of second concave cavities 320 move along with the locking plate 300, and the buckling connection relationship between the second concave cavities 320 and the connecting blocks 220 can be released, so that the connecting plate 220 can be restored to its original position along with the deformation of the conductive spring 240. Obviously, by pressing the button 200 corresponding to the first concave cavity 310, the movement and reset of other buttons 200 can be controlled, and thus the function of one-key reset can be realized.
[0043] A locking head 321 is arranged in the second concave cavity 320, and the locking head 321 is detachably cooperated with the corresponding connecting block 220. Among them, the locking head 321 is a wedge-shaped body structure, the inclined surface of the wedge-shaped body structure is movably in contact and cooperates with the connecting block 220, and the plane of the wedge-shaped body structure is detachably in contact with the plane of the connecting block 220. When the connecting block 220 moves along with the button 200, the connecting block 220 first moves on the inclined surface of the locking head 321, and can push the locking plate 300 to move in the direction of compressing the elastic member to store energy. When the connecting block 220 continues to move until it is separated from the locking head 321, the locking plate 300 elastically resets. At this time, even if the pressure on the button 200 is withdrawn, the button 200 will be buckled in the housing 100 by the contact between the locking head 321 and the connecting block 220, playing a role in reminding the player that the button has been pressed.
[0044] Obviously, when pressing other buttons 200 corresponding to another second cavity 320, or pressing the button 200 corresponding to the first cavity 310, during the process of driving the locking plate 300 to move in the direction of storing energy in the compression elastic member, the previously buckled button 200 in the housing 100 can be released.
[0045] A plurality of connection holes 410 are respectively arranged on the circuit board 400 corresponding to the plurality of buttons 200, and a connection shaft 210 is movably fitted in each connection hole 410. Concentric first conductive rings 420 and second conductive rings 430 are arranged on the circuit board 400 with the centers of the respective connection holes 410 as the centers. Among them, the diameter of the first conductive ring 420 is larger than the diameter of the second conductive ring 430. Both the first conductive ring 420 and the second conductive ring 430 are conductive metal structures, and during the process of deformation and restoration of the deformation of the conductive spring 240, the first conductive ring 420 and the second conductive ring 430 can achieve conductive connection and power-off connection through the conductive spring 240.
[0046] Specifically, the conductive spring 240 is in the shape of a funnel with one end extending outwards. The conductive spring 240 has a first end 241 in contact with the first conductive ring 420 and a second end 242 that can be separably in contact with the second conductive ring 430. Among them, the extended section of the conductive spring 240 is fixed on the connection shaft 210, and the second end 242 is located on the extended section. When the connection shaft 210 is forced to move downward, the extended section deforms, so that the second end 242 can move with the connection shaft 210 to contact the second conductive ring 430, and then cooperate with the first end 241 to conductively connect the first conductive ring 420 and the second conductive ring 430 to conduct the corresponding circuit in the circuit board 400 to realize the corresponding circuit function. When the connection block 220 is separated from the locking head 321, the conductive spring 240 can deform and reset, that is, the conductive spring 240 can drive the connection shaft 210 to reset and move. At this time, the second end 242 moves with the connection shaft 210 to separate from the second conductive ring 430, so that the first conductive ring 420 and the second conductive ring 430 are in a power-off connection state, and then the corresponding circuit in the circuit board 400 is cut off to turn off the corresponding circuit function.
[0047] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
