Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a dimmer. Background Art

[0002] When it is necessary to adjust the brightness of the lamp body, it can be adjusted by a dimmer. When the dimmer is in use, the button on the dimmer is pressed to trigger the control contact inside the regulator, and then the spring is used for resetting. When the elastic force of the spring for resetting the button is large, the pressing force required for the button is also large, and the use experience is poor. When the elastic force of the spring for resetting the button is small, it is difficult for the button to be completely reset after the pressure is removed, resulting in a relatively loose position of the button. Therefore, a dimmer with a better use experience is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dimmer to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or creation condition.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A dimmer, comprising: a housing; a control board connected inside the housing, a control contact is arranged on the top side of the control board, and shock pads are respectively arranged on the control contacts; a button is movably arranged on the housing in the up and down direction, a pressing column extending downward is connected to the bottom side of the button, an avoidance hole is arranged on the housing opposite to the pressing column, a spring is arranged between the bottom side of the button and the housing, and when the button moves downward, the spring can be compressed and deformed, and the pressing column can be abutted against the shock pad.

[0006] This technical solution has at least the following beneficial effects: When it is necessary to use the dimmer to adjust the light effect of the lamp, the button is pressed downward, the spring between the bottom side of the button and the housing is compressed, the pressing column at the bottom side of the button passes through the avoidance hole downward, and abuts against the shock pad, and the control contact is pressed and controlled through the shock pad, reducing the noise generated when the control contact works. When the pressure on the button is removed, the spring returns upward, and at the same time, the shock pad can also assist the button to return upward, ensuring the button reset effect even after reducing the elastic force provided by the spring. In addition, the button can also be set so that the pressing column at its bottom side directly abuts against the shock pad in the initial state. When a force is applied to the button, the pressing column at the bottom side of the button directly acts on the shock pad to press the control contact. In this way, the button structure on the dimmer is more compact, the noise is smaller during use, and the control sensitivity is higher, improving the use experience of controlling and adjusting the lamp.

[0007] As a further improvement of the above technical solution, an installation cylinder extending downward is connected to the bottom side of the button. An installation hole is provided on the outer shell. The spring is sleeved outside the installation cylinder. The installation cylinder passes downward through the installation hole, and an anti-detachment block is connected to the bottom end of the installation cylinder. The button passes through the installation hole on the outer shell through the installation cylinder on its bottom side, so as to realize a vertically movable connection with the outer shell. After the button is pressed and used, the elastic force of the spring pushes the button upward to reset. By using the interference between the anti-detachment block at the bottom end of the installation cylinder and the position of the installation hole, the direct upward detachment of the installation cylinder from the installation hole of the outer shell can be restricted.

[0008] As a further improvement of the above technical solution, the installation cylinder includes two arc-shaped insertion blocks spaced and connected to the bottom side of the button. The spring is sleeved outside the two arc-shaped insertion blocks, and the anti-detachment block is connected to the bottom end of at least one of the arc-shaped insertion blocks. The two spaced arc-shaped insertion blocks can elastically approach each other by using the spaced position between the two arc-shaped insertion blocks to reduce the volume occupied by the entire installation cylinder. In this way, when the installation cylinder is inserted into the installation hole, the two arc-shaped insertion blocks can be elastically approached to each other and then inserted into the installation hole, so that the anti-detachment block can pass through the installation hole. After the installation is completed, the two arc-shaped insertion blocks elastically recover in the direction away from each other. At this time, the anti-detachment block cannot directly upwardly detach from the installation hole.

[0009] As a further improvement of the above technical solution, at least two installation cylinders are arranged at intervals in the horizontal direction. Springs are respectively sleeved outside the two installation cylinders, and the pressing column is located between the two installation cylinders. One installation cylinder on the bottom side of the button and one installation hole on the outer shell form a vertically movable limit. In this way, at least two vertically movable limits arranged at intervals are formed between the button and the outer shell, and the pressing column is arranged between the two installation cylinders, which can improve the stability of the vertical movement of the button and better apply force to the control contacts on the control board through the pressing column.

[0010] As a further improvement of the above technical solution, the housing includes a bottom box, a circuit board, a mounting bracket and a face cover. The bottom box encloses a cavity with an upward opening. The circuit board is connected inside the bottom box. The mounting bracket is connected to the opening position of the bottom box. The mounting bracket encloses a downwardly disposed mounting groove. The control board is connected inside the mounting groove. The avoidance hole is disposed on the top side of the mounting bracket. The button is disposed on the top side of the mounting bracket in the vertical direction. The face cover is provided with a hole for avoiding the button. The face cover is connected to the top side of the bottom box. During installation, the bottom box can be buried in an external structural member and the panel is exposed. The panel can be used to cover and decorate the position of the bottom box part. A cavity for receiving and installing electrical components is enclosed inside the bottom box. The circuit board for power connection can be installed inside the bottom box. The mounting bracket is installed at the opening position of the cavity inside the bottom box, which can block and seal the internal space of the bottom box. The button is disposed on the top side of the mounting bracket in the vertical direction. At this time, the spring is located between the bottom side of the button and the top side of the mounting bracket. And a mounting groove for installing the control board is enclosed on the bottom side of the mounting bracket. During use, the button passes downward through the avoidance hole and abuts against the shock pad on the control contact point.

[0011] As a further improvement of the above technical solution, positioning ribs are disposed around the avoidance hole on the bottom side of the mounting bracket. The shock pad is located inside the positioning ribs. The positioning ribs on the bottom side of the mounting bracket extend in a circular shape, forming a positioning groove on the bottom side of the mounting bracket. During assembly, the shock pad can be first installed in the positioning groove, which is convenient for positioning the shock pad and improves the overall assembly efficiency.

[0012] As a further improvement of the above technical solution, clamping blocks are disposed inside the mounting bracket. The bottom surface of the clamping block inclines towards the center of the mounting bracket. A plurality of clamping blocks are spaced around the inside of the mounting bracket. The control board is located on the top sides of the plurality of clamping blocks. Due to the inclined design of the bottom surface of the clamping block, an inclined surface for guiding the installation of the control board is formed. During assembly, the side of the control board is guided along the bottom surface of the clamping block, and after passing over the clamping block, it is moved to the top side of the clamping block. Then the control board can be clamped and positioned by the clamping blocks, and the control board is supported by the plurality of clamping blocks to prevent the control board from coming out.

[0013] As a further improvement of the above technical solution, a limiting rib is connected to the top side of the mounting bracket. The limiting rib abuts against the inner side of the button. The limiting rib abuts against the inner side of the button, which can further limit the position of the button and improve the stability of the button during use.

[0014] As a further improvement of the above technical solution, a lamp body is connected to the top side of the control board. A light guide body is connected to the position on the mounting bracket opposite to the lamp body. During use, the lamp body transmits light outward through the light guide body. The light guide body can be used to improve the uniformity of the light output. The user can better judge the control and adjustment situation by observing the light effect of the light guide body.

[0015] As a further improvement of the above technical solution, a metal plate is connected inside the bottom box, and the metal plate is exposed outside the bottom box. The whole dimmer can be conveniently grounded through the metal plate, improving the overall safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0027] Refer to Figure 1 And Figure 2 , a dimmer, comprising a housing 100, a control board 200 and a button 300. Among them, the control board 200 is connected inside the housing 100. A control contact 210 is arranged on the top side of the control board 200, and shock pads 220 are respectively arranged on the control contact 210. The button 300 is movably arranged on the housing 100 in the up and down direction. A pressing column 310 extending downward is connected to the bottom side of the button 300. An avoidance hole 131 is arranged at the position of the housing 100 facing the pressing column 310. A spring 320 is arranged between the bottom side of the button 300 and the housing 100. When the button 300 moves downward, the spring 320 can be compressed and deformed, and the pressing column 310 can be abutted against the shock pad 220.

[0028] As can be seen from the above, when it is necessary to use a dimmer to adjust the light effect of a lamp, the button 300 is pressed downward. The spring 320 located between the bottom side of the button 300 and the housing 100 is compressed. The pressing post 310 on the bottom side of the button 300 passes downward through the avoidance hole 131 and presses against the shock pad 220. The control contact 210 is pressed and controlled through the shock pad 220, reducing the noise generated when the control contact 210 works. When the pressure on the button 300 is removed, the spring 320 returns upward. At the same time, the shock pad 220 can also assist the button 300 to reset upward, ensuring the reset effect of the button 300 even after reducing the elastic force provided by the spring 320. In addition, the button 300 can be set in the initial state, and the pressing post 310 on its bottom side also directly abuts against the shock pad 220. When a force is applied to the button 300, the pressing post 310 on the bottom side of the button 300 directly acts on the shock pad 220 to press down the control contact 210. In this way, the structure of the button 300 on the dimmer is more compact, with less noise during use and higher control sensitivity, improving the user experience of controlling and adjusting the lamp.

[0029] In practical applications, there are multiple buttons 300. According to the different functions of the buttons 300, the buttons 300 can be configured into different sizes. Multiple buttons 300 are arranged side by side on the housing 100. Correspondingly, there are also multiple control contacts 210 on the control board 200. Multiple avoidance holes 131 are respectively provided at positions on the housing 100 opposite to the multiple control contacts 210. At this time, the pressing posts 310 on the bottom sides of the multiple buttons 300 can respectively pass through the multiple avoidance holes 131 to act on the multiple control contacts 210.

[0030] The button 300 can move relative to the housing 100 in the up and down direction, and there are various structural forms. For example, the outer side of the button 300 is directly connected to the housing 100 in a sliding rail and sliding groove manner. In this embodiment, an installation cylinder extending downward is connected to the bottom side of the button 300. An installation hole is provided on the housing 100. The spring 320 is sleeved outside the installation cylinder. The installation cylinder passes downward through the installation hole. An anti - detachment block 330 is connected to the bottom end of the installation cylinder. The button 300 passes through the installation hole on the housing 100 through the installation cylinder on its bottom side, thereby realizing a movable connection with the housing 100 in the up and down direction. After the button 300 is pressed and used, the elastic force of the spring 320 pushes the button 300 upward to reset. By using the interference between the anti - detachment block 330 at the bottom end of the installation cylinder and the position of the installation hole, the direct upward detachment of the installation cylinder from the installation hole of the housing 100 can be restricted.

[0031] For the convenience of assembling the installation cylinder and the housing 100, in this embodiment, as Figure 5As shown, the mounting cylinder includes two arc-shaped insertion blocks 340 that are spaced and connected to the bottom side of the button 300. Both arc-shaped insertion blocks 340 extend in the vertical direction, and both arc-shaped insertion blocks 340 arch in a direction away from each other to facilitate elastic deformation. The spring 320 is sleeved outside the two arc-shaped insertion blocks 340, and the anti-detachment block 330 is connected to the bottom end of at least one of the arc-shaped insertion blocks 340. The space between the two spaced arc-shaped insertion blocks 340 can elastically approach each other by using the space position between the two arc-shaped insertion blocks 340, so as to reduce the volume occupied by the entire mounting cylinder. Thus, when inserting the mounting cylinder into the mounting hole, the two arc-shaped insertion blocks 340 can be elastically approached to each other and then inserted into the mounting hole, so that the anti-detachment block 330 can pass through the mounting hole. After installation, the two arc-shaped insertion blocks 340 elastically recover in a direction away from each other. At this time, the anti-detachment block 330 cannot directly move upward out of the mounting hole.

[0032] In order to improve the stability of the button 300 moving in the vertical direction on the housing 100, in this embodiment, at least two mounting cylinders are arranged at intervals in the horizontal direction. The springs 320 are respectively sleeved outside the two mounting cylinders. The pressing column 310 is located between the two mounting cylinders. For example, for a button 300 with a small volume, two mounting cylinders can be arranged at intervals in the horizontal direction. At this time, avoidance holes 131 are respectively arranged at positions on the housing 100 opposite to the two mounting cylinders. For a button 300 with a large volume, four mounting cylinders can be distributed in a rectangle at the bottom side of the button 300. At this time, avoidance holes 131 are respectively arranged at positions on the housing 100 opposite to the four mounting cylinders. One mounting cylinder at the bottom side of the button 300 and one mounting hole on the housing 100 form a vertical movement limit. Thus, at least two spaced vertical movement limits are formed between the button 300 and the housing 100, and the pressing column 310 is arranged between the two mounting cylinders, which can improve the stability of the button 300 moving up and down and better apply force to the control contacts 210 on the control board 200 through the pressing column 310.

[0033] As a specific embodiment of the housing 100, the housing 100 includes a bottom box 110, a circuit board 120, a mounting bracket 130 and a face cover 140. The bottom box 110 encloses a cavity with an upward opening. The circuit board 120 is connected inside the bottom box 110. A top post can be provided at the bottom side of the cavity. Placing the circuit board 120 on the top post can conveniently position the circuit board 120. Screws are driven into the top post through the circuit board 120 to further fasten the circuit board 120 inside the bottom box 110. A wire hole is opened at the bottom side of the bottom box 110, and an external wire can pass through the wire hole and be connected to the circuit board 120, thereby realizing electrical connection with the circuit board 120. The mounting bracket 130 is connected to the opening position of the bottom box 110. The mounting bracket 130 can be connected to the inner side of the bottom box 110 by a buckle. A step can be provided on the inner side of the bottom box 110, and when the mounting bracket 130 is inserted into the bottom box 110, it can be conveniently positioned on the step. The mounting bracket 130 encloses a downwardly disposed mounting groove. The control board 200 is connected inside the mounting groove. The avoidance hole 131 is provided on the top side of the mounting bracket 130. At this time, the mounting hole is opened on the top side of the mounting bracket 130. The button 300 is arranged on the top side of the mounting bracket 130 in the up and down direction. The face cover 140 is provided with a hole 141 for avoiding the button 300. The face cover 140 is connected to the top side of the bottom box 110. The face cover 140 can also be connected to the top side of the bottom box 110 by a buckle.

[0034] For this housing 100, the bottom box 110 can be buried in an external structural member and the panel is exposed. The panel can be used to shield and decorate the position of the bottom box 110 part. A cavity for receiving and installing electrical components is enclosed inside the bottom box 110. The circuit board 120 for power connection can be installed inside the bottom box 110. The mounting bracket 130 is installed at the opening position of the cavity inside the bottom box 110, which can shield and block the internal space of the bottom box 110. The button 300 is arranged on the top side of the mounting bracket 130 in the up and down direction. At this time, the spring 320 is located between the bottom side of the button 300 and the top side of the mounting bracket 130. A mounting groove for installing the control board 200 is enclosed on the bottom side of the mounting bracket 130. During use, the button 300 passes downward through the avoidance hole 131 and abuts against the shock-absorbing pad 220 on the control contact 210.

[0035] Since it is necessary to align the shock-absorbing pad 220 with the control contact 210 on the control board 200, as Figure 4As shown, it is necessary to improve the stability of the installation of the shock pad 220 on the mounting bracket 130. In this embodiment, a positioning rib 132 is provided around the avoidance hole 131 on the bottom side of the mounting bracket 130, and the shock pad 220 is located within the positioning rib 132. The positioning rib 132 on the bottom side of the mounting bracket 130 extends in a circumferential manner, forming a positioning groove on the bottom side of the mounting bracket 130. During assembly, the shock pad 220 can be first installed into the positioning groove, thereby facilitating the positioning of the shock pad 220 and improving the overall assembly efficiency.

[0036] In addition, in order to facilitate the positioning of the spring 320, a fixing rib can also be provided on the top side of the mounting bracket 130. The fixing rib extends around the avoidance hole 131. When installing the spring 320, the spring 320 can be directly placed on the top side of the mounting bracket 130 and abutted against the inner side of the fixing rib, thereby improving the convenience of installing the spring 320.

[0037] In order to facilitate the installation and fixation of the control board 200 within the mounting bracket 130, the control board 200 can be fixed within the mounting bracket 130 by means of snap connection. In this embodiment, a clamping block 133 is provided on the inner side of the mounting bracket 130. The bottom surface of the clamping block 133 is inclined towards the direction close to the center of the mounting bracket 130. A plurality of clamping blocks 133 are arranged at intervals around the inner side of the mounting bracket 130, and the control board 200 is located on the top side of the plurality of clamping blocks 133. Due to the inclined design of the bottom surface of the clamping block 133, an inclined surface for installation guidance can be formed for the installation of the control board 200. During assembly, the side of the control board 200 is guided along the bottom surface of the clamping block 133, moves over the clamping block 133 and then moves to the top side of the clamping block 133, so that the control board 200 can be clamped and positioned by the clamping block 133, and the control board 200 can be supported by the plurality of clamping blocks 133 to prevent the control board 200 from coming out.

[0038] In order to further improve the limiting effect on the button 300, as Figure 3 shown, in this embodiment, a limiting rib 134 is connected to the top side of the mounting bracket 130, and the limiting rib 134 abuts against the inner side of the button 300. The limiting rib 134 abuts against the inner side of the button 300, which can further limit the position of the button 300 and improve the stability of the use of the button 300.

[0039] In some embodiments, a lamp body is connected to the top side of the control board 200, and a light guide 230 is connected to the mounting bracket 130 at a position opposite to the lamp body. During use, the lamp body transmits light outward through the light guide 230. The light guide 230 can be used to improve the uniformity of the light output. The user can better judge the control and adjustment situation by observing the lighting effect of the light guide 230. In practical applications, there can be multiple lamp bodies. At this time, there are also multiple light guides 230. The multiple light guides 230 are respectively opposite to the multiple lamp bodies, and multiple independent channels are formed in the mounting bracket 130. The multiple light guides 230 are respectively inserted into the multiple channels, so as to reduce the problem of light leakage between the multiple light guides 230.

[0040] In order to facilitate the grounding of the wires in the bottom box 110 and improve the structural strength of the bottom box 110, in this embodiment, a metal plate 111 is connected inside the bottom box 110, and the metal plate 111 is exposed outside the bottom box 110. The entire dimmer can be easily grounded through the metal plate 111, improving the overall safety of use. In practical applications, a through groove is formed inside the bottom box 110, and the metal plate 111 is a plate body with multiple bends. The metal plate 111 includes a bottom connection section, side vertical sections and flat sections. Two side vertical sections are formed by bending the two sides of the bottom connection section upward. The bottom connection section is connected to the bottom side of the bottom box 110. The two side vertical sections are respectively located at both ends of the through groove of the bottom box 110, and together with the bottom box 110 itself, they enclose the above-mentioned cavity. Flat sections are respectively connected to both sides of the two side vertical sections, and the two flat sections extend in directions away from each other. At this time, the mounting bracket 130 is connected to the top side of the bottom box 110 and is located between the two side vertical sections, and the two end portions of the face cover 140 are respectively connected to the two flat sections. When wiring, the external wires pass through the bottom side of the bottom box 110, the bottom connection section and are connected to the circuit board 120. The wires that need to be grounded can be directly connected to the side vertical sections, and the entire metal plate 111 can also be used to strengthen the structural strength of the bottom box 110.
