Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a button structure and a lamp with the button structure. Background Art

[0002] As a lighting tool, lamps come in many different types depending on where they are used. Camping lanterns or work lights are common, and there are many types of work lights, including floodlights and panel lights. Work lights not only provide illumination but also serve a decorative purpose. They are commonly used in various workplaces, such as offices, workshops, workbenches, outdoor areas, and underground, providing lighting for people to work.

[0003] Work lights or camping lights used in the workplace or outdoors require buttons, knobs, and other controls to turn the lights on and off, dim them, and so on. To prevent damage to the switch when the work light falls, existing technologies, such as Chinese patent application number 202321296614.X, disclose a work light that includes a work light body, the top of which is provided with at least one knob switch for controlling the work light body, each knob switch being provided with a push switch; a protective frame provided on the top of the work light body, the bottom of the protective frame being provided with a first protective groove for protecting the knob switch, the top of the protective frame being provided with a second protective groove for protecting the push switch; and a handle 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 increases the cost, but also interferes with the rotation path of the knob, resulting in inconvenient operation.

[0005] Therefore, there is room for further improvement. Utility Model Content

[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-mentioned button structure.

[0008] The technical solution adopted by the present invention to solve the first technical problem is: a button structure, comprising:

[0009] switch;

[0010] A knob, driving the switch to rotate in a first direction; and

[0011] A button drives the switch to move linearly along a second direction;

[0012] Its characteristics are:

[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 utilizing existing button components and configuring the movement relationships between them, the button exerts pressure on the switch when impacted, causing the switch to move less than its designed travel distance. This limits the maximum travel distance of the switch under impact, protecting it from damage. This structure eliminates the need for additional protective components, simplifies the structure, and does not affect button operation.

[0016] Furthermore, in order to facilitate the rotation and linear movement of the switch, 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] In order to facilitate the reset of the switch 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, which 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 further includes an elastic member, which is sleeved on the outer periphery 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. The ends of the elastic member and the knob bracket cooperate to form a vertical pin, which is positioned within the receiving groove. When the switch is rotated, the elastic member rotates synchronously, preventing the sharp edge of the elastic member from rubbing against the knob and causing abnormal noise when the switch is rotated.

[0023] In order to facilitate 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: the button structure as described above is applied, the lamp holder serves as the 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, in order 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 corresponding position of the knob and the mounting groove and the bottom surface of the mounting groove.

[0026] Compared to the prior art, the present invention has the advantage of utilizing existing components of the button structure and configuring the movement relationship between these components. This ensures that, when the button structure is impacted, the pressure exerted by the button on the switch causes the switch to move a distance less than the designed travel distance. This limits the maximum travel distance of the switch under impact to within its travel distance, thereby protecting the switch from damage. This structure eliminates the need for additional protective components, simplifies the structure, and does not affect the operation of the button. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with 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 orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply 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, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0035] See also Figures 1 to 6 A lamp includes a lamp holder 1 and a button structure 2. The lamp holder 1 serves as the 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 interior of the lamp holder 1 to the exterior of the lamp holder 1. The knob bracket 221 is sleeved around the outer periphery of the switch 23 and is in direct contact with the switch 23. The knob bracket 221 can be fixed with screws 223, thereby acting as a brake on 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 assembled separately, 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 engaged with each other through 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 engaged 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 In the direction indicated by the arrow (or the reverse direction), when the lamp is normally positioned, the rotation axis of the knob 21 is a vertical line extending vertically. Both the positioning protrusion 2211 and the positioning groove 211 extend vertically, allowing for a certain amount of relative vertical movement between the knob 21 and the knob bracket 221. The positions of the positioning protrusion 2211 and the positioning groove 211 are also interchangeable.

[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 be reset after the knob bracket 221 (knob 21) is rotated (e.g., along the Figure 1 The elastic member 24 is twisted by rotating in the counterclockwise direction indicated by the middle arrow, and resetting means rotating in the opposite direction 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 by the positioning protrusion 2211 and the positioning groove 211 together, that is, a groove can also be provided in the positioning groove 211), which matches the vertical pin 241. The vertical pin 241 can be placed in the receiving groove 2212, thereby being clamped between the knob bracket 221 and the knob 21. When the switch 23 is rotated, the elastic member 24 rotates synchronously, thereby preventing the sharp edge of the elastic member 24 from rubbing against the knob 21 and generating abnormal noise when the switch 23 is rotated.

[0038] The knob cover 222 is set 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 can also 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 arrow B, while "resetting" refers to movement in the direction opposite to arrow B until the elastic member 24 is in its natural state. The rotation axis of the switch 23 (knob 21) extends along the second direction B. Because the knob bracket 221 and the knob 21 cooperate through the positioning protrusion 2211 and the positioning groove 211, the knob 21 does not need to be pressed down simultaneously when the button is pressed.

[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 above-mentioned switch 23 passes through the middle of the mounting groove 11, and the knob bracket 221 can partially pass through the middle of the mounting groove 11 into the lamp holder 1.

[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 flat, the bottom end of the knob 21 fits into 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 stroke 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 the fall, the switch 23 will definitely not be damaged.

[0042] Therefore, the design of the knob 21, button and switch 23 can prevent the switch 23 from being damaged when the lamp falls.
