Abstract
Description
Technical Field
[0001] The invention relates to a lighting device, in particular to a button structure and a lamp using the button structure. Background Art
[0002] As a lighting tool, lamps have many types due to their different places of use. Camping lamps or work lamps are common lamps. There are many types of work lamps, such as floodlights and panel lights. Work lamps not only play a lighting role, but also a decorative role. Work lamps are often used in various workplaces, such as offices, workshops, workbenches, outdoors, underground, etc., to provide lighting for people when they work.
[0003] Work lights or camping lights used in the workplace or outdoors require buttons, knobs, etc. to operate the switch, brightness, etc. of the lights. To prevent the switch from being damaged when the work light falls, existing technologies such as a Chinese patent with application number 202321296614.X disclose a work light, including a work light body, the top of the work light body is provided with at least one knob switch for controlling the work light body, and the knob switch is provided with a push switch; a protective frame, the protective frame is provided on the top of the work light body, the bottom of the protective frame is provided with a protective groove 1 for protecting the knob switch, the top of the protective frame is provided with a protective groove 2 for protecting the push switch, and a handle, the handle is rotatably provided on the work light body.
[0004] However, this type of lamp requires an additional protective frame to be provided on the top of the lamp body, which not only increases the overall height of the lamp and the cost, but also interferes with the rotation path of the knob, resulting in inconvenient operation.
[0005] Therefore, there is room for further improvement. Summary of the invention
[0006] The first technical problem to be solved by the present invention is to provide a button structure capable of protecting a switch with a simple structure in view of the deficiencies in the above-mentioned prior art.
[0007] The second technical problem to be solved by the present invention is to provide a lamp having the above button structure.
[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a button structure, comprising:
[0009] switch;
[0010] A knob drives the switch to rotate along a first direction; and
[0011] A button drives the switch to move linearly along a second direction;
[0012] Features:
[0013] Along the second direction, the distance between the top surfaces of the knob and the button is d1, and the movable distance of the knob is d2, wherein the top surfaces of the knob and the button are the sides away from the mounting base of the button structure, and the following relationship is satisfied:
[0014] d2>d1, d2-d1≤h, where h is the designed pressing stroke of the switch.
[0015] By using the existing components of the button structure and setting the motion position relationship between the components, when the button structure is hit, the pressure exerted by the button on the switch causes the switch to move a distance less than the designed stroke of the switch, thereby limiting the maximum movement distance of the switch to not exceed its stroke when hit, thereby protecting the switch from damage. This structure does not require additional protective components, is not only simple in structure, but also does not affect the operation of the button.
[0016] Furthermore, in order to facilitate the switch to rotate and move linearly, the button includes:
[0017] A knob bracket is sleeved on the outer periphery of the switch and fixed to the switch, and the knob is arranged on the outer periphery of the knob bracket and rotates synchronously with the knob bracket; and
[0018] The knob cover is arranged on a side of the knob bracket away from the switch, so as to drive the switch to move along the second direction through the knob bracket.
[0019] To facilitate the switch to reset after being pressed, the button structure further includes an elastic member, which is sleeved on the outer periphery of the knob bracket, so that the button and the switch maintain a tendency to reset by moving in a direction opposite to the second direction.
[0020] Furthermore, in order to facilitate the rotation and resetting of the switch, the button includes a knob bracket, the knob bracket is sleeved on the outer periphery of the switch and fixed to the switch, and the knob is arranged on the outer periphery of the knob bracket and rotates synchronously with the knob bracket;
[0021] The button structure also includes an elastic member, which is sleeved on the outer circumference of the knob bracket, so that the knob and the switch maintain a tendency to rotate in a direction opposite to the first direction and reset.
[0022] Furthermore, one or both of the knob and the knob bracket cooperate to form a receiving groove extending in the second direction, and the ends of the elastic member and the knob bracket cooperate to form a vertical pin, and the vertical pin is placed in the receiving groove. When the switch is rotated, the elastic member will rotate synchronously to avoid the sharp edge of the elastic member rubbing against the knob when the switch is rotated, thereby preventing abnormal noise.
[0023] In order to facilitate the synchronous rotation of the knob and the knob bracket, the inner peripheral wall of the knob and the outer peripheral wall of the knob bracket are matched through a keyway, so that the knob and the knob bracket rotate synchronously.
[0024] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a lamp, which also includes a lamp holder, characterized in that: a button structure as described above is applied, the lamp holder serves as an installation base of the button structure, and the switch extends from the inside of the lamp holder to the outside of the lamp holder.
[0025] Preferably, to facilitate the installation of the button structure, the lamp holder is provided with a mounting groove, which is formed by the lamp holder wall being recessed toward the lamp holder and is ring-shaped, and the switch passes through the middle of the mounting groove, and d2 is the minimum vertical distance between the bottom surface of the knob corresponding to the mounting groove and the bottom surface of the mounting groove.
[0026] Compared with the prior art, the advantages of the present invention are: by using the existing components of the button structure and setting the motion position relationship between the components, when the button structure is hit, the pressure exerted by the button on the switch causes the switch to move a distance less than the designed stroke of the switch, thereby limiting the maximum movement distance of the switch to not exceed its stroke when hit, thereby protecting the switch from damage. This structure does not require additional protection components, is not only simple in structure, but also does not affect the operation of the button. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions.
[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.
[0035] See also Figure 1 to Figure 6 A lamp includes a lamp holder 1 and a button structure 2. The lamp holder 1 serves as a mounting base for the button structure 2. The button structure 2 includes a knob 21, a button, a switch 23, and an elastic member 24. The button includes a knob bracket 221 and a knob cover 222. The switch 23 extends from the inside of the lamp holder 1 to the outside of the lamp holder 1. The knob bracket 221 is sleeved on the outer periphery of the switch 23 and is in direct contact with the switch 23. The two can be fixed by screws 223, so that the knob bracket 221 plays the role of braking the switch 23. The knob 21 is arranged on the outer periphery of the knob bracket 221 so as not to be in direct contact with the switch 23. If it is assembled alone, it will not have any effect.
[0036] The inner circumferential wall of the knob 21 and the outer circumferential wall of the knob bracket 221 are matched by keyways, so that the knob 21 and the knob bracket 221 rotate synchronously. In this embodiment, a positioning groove 211 is formed on the inner circumferential wall of the knob 21, and a positioning protrusion 2211 is formed on the outer circumferential wall of the knob bracket 221. The positioning protrusion 2211 can be inserted into the positioning groove 211 and matched with the positioning groove 211. Therefore, when the knob 21 is installed on the knob bracket 221, the knob 21, the knob bracket 211 and the switch 23 can rotate synchronously, and the rotation direction is the first direction A ( Figure 1 The direction indicated by the arrow in the figure or the reverse direction), that is, when the lamp is placed normally, the rotation axis of the knob 21 is a vertical line extending up and down. The positioning protrusion 2211 and the positioning groove 211 both extend up and down, so that there is a certain space for relative up and down movement between the knob 21 and the knob bracket 221. The positions of the positioning protrusion 2211 and the positioning groove 211 can also be interchanged.
[0037] The elastic member 24 is sleeved on the outer periphery of the knob bracket 221, and is preferably a spring. One end of the elastic member 24 can be in contact with or connected to the lamp holder 1, so as to facilitate the knob bracket 221 (knob 21) to be reset after rotation (such as along the Figure 1 The elastic member 24 is twisted when rotating counterclockwise as indicated by the middle arrow, and resetting means rotating in the opposite direction as indicated by the arrow, that is, clockwise, until the elastic member 24 is in a natural state), which can also improve the hand feel. The other end of the elastic member 24 cooperates with the knob bracket 221. In this embodiment, the ends of the elastic member 24 and the knob bracket 221 cooperate to form a vertical pin 241 extending up and down, and a receiving groove 2212 is formed in the positioning protrusion 2211 (the complete receiving groove 2212 can be formed by the positioning protrusion 2211 or the positioning groove 211 alone, or it can be formed by the positioning protrusion 2211 and the positioning groove 211 together, that is, a groove can also be set in the positioning groove 211), which matches the vertical pin 241. The vertical pin 241 can be placed in the receiving groove 2212, so as to be clamped between the knob bracket 221 and the knob 21. When the switch 23 is rotated, the elastic member 24 will rotate synchronously, so as to avoid the sharp edge of the elastic member 24 rubbing against the knob 21 when the switch 23 is rotated, thereby preventing abnormal noise from being generated.
[0038] The knob cover 222 is arranged on the top of the knob bracket 221. The knob bracket 221 and the switch 23 can be pressed down by pressing the knob cover 222. When pressing down, the elastic member 24 is compressed and thus can be reset by the elastic member 24. "Pressing down" means that the button and the switch 23 are pressed down along the Figure 4 The switch 23 (knob 21) moves in the second direction indicated by the arrow B, and "reset" means moving in the direction opposite to the arrow B until the elastic member 24 is in the natural state. The rotation axis of the switch 23 (knob 21) extends along the second direction B. Since the knob bracket 221 and the knob 21 cooperate with each other through the positioning protrusion 2211 and the positioning groove 211, when the button is pressed, the knob 21 does not need to be pressed down at the same time.
[0039] A mounting groove 11 is provided at the top of the lamp holder 1. The mounting groove 11 is formed by a downward depression of the top of the lamp holder 1 and is ring-shaped. The switch 23 passes through the middle of the mounting groove 11, and the knob bracket 221 can partially pass into the lamp holder 1 from the middle of the mounting groove 11.
[0040] When the assembly is in place and the elastic member 24 is in a natural state, along the second direction B, the top surface of the knob 21 is higher than the top surface of the knob cover 222, and the distance between the two is d1. The minimum vertical distance between the bottom surface of the knob 21 and the mounting groove 11 at the corresponding position and the bottom surface of the mounting groove 11 (the distance along the direction of arrow B) is d2, and d2>d1. d2 is also the distance that the knob 21 can move along the second direction B. After the knob 21 moves this distance, it abuts against the lamp holder 1 and cannot move further. The switch 23 is designed to have a pressable stroke of h. After the switch 23 is pressed at its initial position, the switch 23 will not be damaged within this preset stroke h. The above parameters satisfy: d2-d1≤h. Preferably, d1 is 0.55mm, d2 is 0.6mm, and h is 0.3mm.
[0041] Therefore, when the lamp falls, if the switch 23 falls downward, when the falling surface is a plane, the bottom end of the knob 21 fits with the bottom surface of the mounting groove 11 of the lamp holder 1 at the moment of falling, and the top end of the knob 21 is flush with the top end of the knob cover 222. The travel distance of the knob cover 222 is 0.05mm, and the switch 23 will only be displaced by 0.05mm (0.05mm is less than 0.3mm). The pressing stroke of the switch 23, that is, the button displacement is less than the pressing stroke of the switch 23. When only the top end of the knob 21 is touched during falling, the switch 23 will definitely not be damaged.
[0042] Therefore, through the design of the knob 21, the button and the switch 23, it is possible to avoid the switch 23 being damaged when the lamp falls.
