Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically a wall-mounted circuit switch with a silent structure. Background Technology

[0002] Wall-mounted circuit switches (such as wall switches and panel switches) are among the most basic and frequently used control components in building electrical systems. Their core function is to safely and reliably switch circuits on and off. Traditional mechanical switches typically employ a rocker or push-button structure, and their working principle relies on the rapid contact and separation between the internal moving contact (usually a copper spring) and the static terminal. During this process, mechanical collisions inevitably occur between the moving parts.

[0003] In pursuit of trigger sensitivity and a clear on / off feel, traditional switches often rely on direct, high-speed collisions between metal components (such as copper contacts and brass terminals). This hard impact produces a crisp, loud "click" sound. In places requiring a quiet environment, such as at night, in a study, or in a bedroom, this noise can disturb users and affect their rest or concentration.

[0004] To address the noise problem, the industry has made some attempts, but most of them involve adding flexible materials such as rubber and plastic at the contact points of metal parts to absorb noise. However, due to the electric arc generated when the metal parts are connected, they are prone to deformation or even melting, which leads to the failure of the damping effect, increased contact resistance, and even safety hazards such as switch overheating, seriously affecting the life and reliability of the switch. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall circuit switch with a silent structure, including a base, a mounting panel fixed on the front surface of the base, and a protective frame snapped onto the side of the mounting panel.

[0006] A switch cover is movably connected to the front surface of the mounting panel, and the switch cover is located inside the protective frame.

[0007] The base is equipped with a power connection mechanism, which includes two terminals arranged vertically inside the base, namely a power-off terminal and a power-on terminal, and a copper contact plate that contacts the two terminals in sequence.

[0008] The base also has a rocker plate fixed to the back of the switch cover, and a control mechanism for controlling the rocker plate swing is set at the shaft position on the back of the rocker plate.

[0009] On the back of the rocker, along its length, there is a buffer mechanism to reduce the noise generated when the circuit is turned on or off.

[0010] Preferably, rotating knobs are fixed symmetrically at the pivot positions on both sides of the rocker.

[0011] The base is equipped with a stabilizing mechanism, which includes a collar fixed inside the base and symmetrically arranged near the front end. The rotating knob is rotatably connected inside the collar.

[0012] Preferably, the side circumferential array of the rotary knob has multiple positioning holes.

[0013] The side of the collar has a positioning interface, and a positioning rod is movably sleeved in the positioning interface. The front end of the positioning rod is inserted into the corresponding positioning hole.

[0014] Preferably, the inner side of the collar is symmetrically provided with protrusions, and the side of the positioning rod is symmetrically provided with strip grooves along its length, and the protrusions are slidably connected in the strip grooves.

[0015] Preferably, a limiting ring is fixed to the tail end of the positioning rod, and the limiting ring is attached to the side of the collar at a set position.

[0016] Preferably, a retraction spring is movably sleeved on the side of the positioning rod, with the two ends of the retraction spring respectively abutting the corresponding surfaces of the collar and the limiting ring.

[0017] Preferably, the control mechanism includes a sleeve fixed to the shaft core position on the back of the rocker, a sleeve rod movably sleeved inside the sleeve, and a ball bearing embedded in the front end of the sleeve rod, with the ball bearing adhering to the surface of the copper contact plate.

[0018] Preferably, a spring rod is movably sleeved inside the sleeve, with both ends of the spring rod respectively attached to the inside of the sleeve and the opposite surface of the sleeve rod.

[0019] Preferably, the buffer mechanism includes two arc-shaped rods fixed parallel to each other on the back of the rocker, away from the shaft core and on both sides. The two ends of the arc-shaped rods are provided with mating grooves, which fit against the side of the copper plate at a set angle.

[0020] Preferably, a buffer pad is fixed inside the mating groove, and the buffer pad is attached to the corresponding surface of the copper connector plate.

[0021] Compared with the prior art, this utility model provides a wall circuit switch with a silent structure, which has the following beneficial effects:

[0022] 1. This wall-mounted circuit switch with a silent structure features a unique buffer mechanism that intervenes instantaneously before the metal conductive parts come into contact. Through elastic materials and soft contact, it effectively absorbs and buffers most of the impact kinetic energy, fundamentally avoiding the problem of crisp noise caused by hard metal impacts. This achieves an extremely quiet operation, making it particularly suitable for bedrooms, studies, and other places that require a quiet environment.

[0023] 2. This wall-mounted circuit switch with a silent structure absorbs mechanical impact energy through a buffer mechanism without participating in conduction or enduring electric arcs for extended periods. It is mainly composed of rubber pads set on a non-conductive arc-shaped rod, avoiding safety hazards such as increased contact resistance and overheating caused by aging and melting of soft materials. Furthermore, the control mechanism ensures that current switching is reliably completed by high-performance metal copper contact plates and terminals, thus achieving silent operation while fully guaranteeing the switch's electrical performance, safety, and mechanical lifespan.

[0024] 3. This wall-mounted circuit switch with a silent structure generates a slight tactile vibration feedback when the switch is in position, through the cooperation of a spring-driven positioning rod and a silicone ring. This allows the operator to clearly perceive whether the operation is in place, improving the confidence of the operation and the user experience. At the same time, both the silent structure and the feedback structure are based on a sophisticated mechanical design. The core buffer component has a simple structure, is easy to process and assemble, and does not require complex hydraulic, pneumatic or electronic components. While achieving excellent silent performance and good feel, it effectively controls manufacturing costs and is conducive to large-scale production and promotion. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] Please see Figure 1 - Figure 8 As shown, the wall circuit switch with a silent structure proposed in this embodiment includes a base 1, on which a mounting panel 2 is fixed by screws. The mounting panel 2 has a slot on its side edge, and a buckle is provided on the inner side of the protective frame 3. The buckle is engaged in the slot to fully fix the protective frame 3 and the mounting panel 2.

[0041] The front surface of the mounting panel 2 is movably connected to a switch cover 4. The size of the switch cover 4 matches the size inside the protective frame 3, and the upper and lower sides of the cover are arc-shaped, so as to ensure that when the two ends of the switch cover 4 are tilted, the two sides rotate in an arc, avoiding the switch cover 4 from hitting the inner wall of the protective frame 3.

[0042] The base 1 is equipped with a power connection mechanism 11, which includes a power-off terminal 111 and a power-on terminal 112 arranged vertically at the top and bottom of the base 1, and a copper contact plate 12 that can swing around its central pivot point. The copper contact plate 12 can alternately contact the power-off terminal 111 or the power-on terminal 112 during the swing to realize the circuit switching.

[0043] The base 1 also has a rocker plate 13 fixed to the back of the switch cover 4. Its front side is fixed to the back of the switch cover 4 by a snap-fit ​​structure. At the same time, rotating knobs 131 are symmetrically fixed at the shaft cores on both sides of the rocker plate 13. The base 1 is equipped with a stabilizing mechanism 16, which includes two collars 161 symmetrically fixed on both sides of the front end of the base 1. The rotating knobs 131 are inserted into the collars 161 and can rotate, so that when either end of the switch cover 4 is pressed, the cover and the rocker plate 13 swing around the rotating knobs 131 as the shaft core.

[0044] Meanwhile, a control mechanism 14 for controlling the rocker plate 12 rocker-type swing is provided at the shaft position on the back of the rocker 13. It includes a sleeve 141 integrally formed with the switch cover 4, and a sleeve rod 142 with a diameter matching its inner diameter is slidably sleeved in the sleeve 141. A ball 143 is embedded at the front end of the sleeve rod 142. At the same time, a spring rod 144 is also installed in the sleeve 141. Its two ends are respectively pressed against the inner bottom of the sleeve 141 and the inner end of the sleeve rod 142, so that the ball 143 maintains elastic contact with the copper plate 12. When the rocker 13 swings, the elastic force is used to control the extension and retraction of the sleeve rod 142 in the sleeve 141, so that the ball 143 always rolls against the upper surface of the copper plate 12, ensuring that the copper plate 12 can swing smoothly and steadily.

[0045] Two elastic arc-shaped rods 151 are fixed parallel to each other on the back of the rocker 13 along its length and between the shaft and both sides, forming a buffer mechanism 15. The two ends of the arc-shaped rods 151 are provided with mating grooves 152, and rubber buffer pads 153 are glued in the grooves. When the rocker 13 swings to a certain angle (when the switch cover 4 is not fully pressed into place, one end of the copper contact plate 12 is about to be attached to the corresponding terminal, but has not yet made contact), the mating grooves 152 are just locked into the side edge of the copper contact plate 12. The buffer pads 153 effectively absorb the collision energy in advance, so that when the switch cover 4 is fully pressed into place, one end of the copper contact plate 12 is fully attached to the corresponding terminal, thus achieving a silent power switching effect.

[0046] The working principle of the wall circuit switch with silent structure proposed in this embodiment is as follows: When in use, the user presses either end (on or off) of the switch cover 4, and the switch cover 4 drives the rocker 13 that is fixed to it to move together. At this time, the rocker 13 swings around the rotating knob 131 as the axis, and the adjustment mechanism 14 on the back of the rocker 13 moves accordingly. The ball 143 at its front end is always in close contact with and rolls on the upper surface of the copper contact plate 12 under the elastic force provided by the spring rod 144. This rolling contact transforms the swing of the rocker 13 into a smooth push on the middle of the copper contact plate 12, causing the copper contact plate 12 to start swinging around its fulcrum.

[0047] Just before the copper contact plate 12 is about to contact the power-off terminal 111 or the power-on terminal 112, the buffer mechanism 15 on the back of the rocker 13 starts to function. The mating groove 152 at the front end of the arc-shaped rod 151 fixed on the rocker 13 is precisely engaged with the side edge of the copper contact plate 12. The rubber buffer pad 153 bonded therein makes soft contact with the copper contact plate 12 first, effectively absorbing and buffering most of the collision kinetic energy.

[0048] Subsequently, the switch cover 4 is fully pressed into place, and the control mechanism 14 continues to push the copper contact plate 12 so that one end overcomes the greatly reduced impact force and smoothly and gently makes full contact with the corresponding terminal (power-on terminal 112 or power-off terminal 111) to complete the connection or disconnection of the circuit. Since the main impact energy has been absorbed by the buffer pad 153, hard impact between the metal parts (copper contact plate 12 and terminal) is avoided, thus achieving a silent operation effect.

[0049] Example 2

[0050] Please see Figure 3 - Figure 8 As shown, the wall circuit switch with a silent structure proposed in this embodiment, based on the first embodiment, further includes multiple positioning holes 132 evenly distributed around the side of the rotating knob 131, and a positioning interface 162 on the side of the collar 161, in which a positioning rod 163 is inserted. The front end of the positioning rod 163 can be inserted into a positioning hole 132, thereby ensuring that the switch cover 4 is fully pressed into place.

[0051] The collar 161 has symmetrical protrusions 1611 on its inner side, and the positioning rod 163 has two symmetrical strip grooves 1631 on its side. The protrusions 1611 slide into the grooves, so that the positioning rod 163 can only move axially and cannot rotate. The tail end of the positioning rod 163 is welded with a limit ring 164. When it is in the closed position, the limit ring 164 fits against the outside of the collar 161. The positioning rod 163 is fitted with a contraction spring 165, and its two ends press against the outer wall of the collar 161 and the inner side of the limit ring 164 respectively, so that the positioning rod 163 maintains the tendency to insert forward.

[0052] It should be further explained that the front end of the positioning rod 163 is round, and the side near the front end is provided with an elastic silicone ring. The round button at the front end of the positioning rod 163 is inserted into the corresponding positioning hole 132 to provide feedback force, and facilitates the front end of the positioning rod 163 to quickly disengage from the positioning hole 132 when the other end of the switch cover 4 is pressed.

[0053] During the insertion and positioning process, the silicone ring on the side of the positioning rod 163 collidees with the edge of the positioning hole 132 interface, causing the rocker 13 and the switch cover 4 to vibrate slightly for feedback while avoiding impact and noise.

[0054] The working principle of the wall circuit switch with a silent structure proposed in this embodiment is as follows: its basic silent switching principle is exactly the same as that of Embodiment 1. The difference is that the positioning structure added in this embodiment mainly provides feedback force when the switch cover is fully pressed into place. When the rocker 13 rotates with the rotating knob 131 as the axis until the docking groove is inserted into the side edge of the copper plate for buffering and absorbing the collision force, the positioning rod 163 is not inserted into any positioning hole 132. When the switch cover is fully pressed into place, the contraction force of the contraction spring 165 pulls the limit ring 164, so that the positioning rod 163 is quickly inserted into the corresponding positioning hole 132. When the positioning rod 163 approaches the elastic silicone ring around the front side and hits the edge of the interface of the positioning hole 132, the switch cover 4 vibrates slightly, thereby providing feedback to the operator so that the operator can clearly know that the switch cover is pressed into place.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
