Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] like Figure 1-Figure 14 As shown, a lighting device with a multi-level switch function and a slidable protective cover provided in an embodiment of the present application is now described in detail.

[0042] The lighting device includes: a shell 1, a power supply 3, a light source 2, a sliding cover assembly 4, a high and low beam switch circuit board 6, a display button integrated assembly 5, a main board 51, a mounting bracket 52 and a charging module 7; the power supply 3 and the light source 2 are arranged at both ends of the shell 1, the power supply 3 is close to the rear end of the shell 1, the charging module 7 is arranged at the rear end of the shell 1 and is electrically connected to the power supply 3 for charging the power supply 3, the power supply 3 is a battery, and the light source 2 is a multi-lamp bead module, which can realize functions such as high and low beam, red light, yellow light, blue light, spotlight and floodlight.

[0043] The far and near switch circuit board 6 is fixed on the mounting bracket 52 and arranged side by side with the display button integrated component 5. The main board 51 is fixed to the bottom of the mounting bracket 52 by screws. The display button integrated component 5 is lifted and lowered on the mounting bracket 52. A notch 11 is provided above the display screen 55 close to the display button integrated component 5 on the shell 1. The sliding cover component 4 is slidably arranged on the shell 1 and can open or close the notch 11 to make the display screen 55 visible or hidden in the notch 11; the sliding cover component 4 has a protective cover function. When in use, the display screen 55 is displayed for customers to perform button operations and view information. When not in use, the display screen 55 is hidden and protected.

[0044] In this embodiment, an on / off switch 61 and a high / low beam switching switch 62 are provided on the high / low beam switch circuit board 6 at intervals. The on / off switch 61 is used to control the on / off of the light source 2, and the high / low beam switching switch 62 is used to switch between high beam and low beam. A touch bar 45 is provided on the sliding cover assembly 4. On the sliding path of the sliding cover assembly 4, the touch bar 45 can only touch the on / off switch 61 or the high / low beam switching switch 62 at a time, that is, the interval between the on / off switch 61 and the high / low beam switching switch 62 on the sliding path of the sliding cover assembly 4 is greater than the width of the touch bar 45, which can ensure that the touch bar 45 will not touch the on / off switch 61 and the high / low beam switching switch 62 when it stays in the interval. The sliding cover assembly 4 can enable the touch bar 45 to touch the on / off switch 61 or the high / low beam switching switch 62 during the sliding process. In this way, the on / off switch 61 and the high / low beam switching switch 62 can be triggered by sliding the sliding cover assembly 4. The user only needs to slide the sliding cover assembly 4 to unlock, turn on and switch the high / low beam mode of the lighting device, which greatly simplifies the operation steps.

[0045] In this embodiment, if Figure 5 , Figure 7-Figure 14As shown, the sliding cover assembly 4 includes a top plate 41 and a sliding block 42 . The top plate 41 acts as a protective cover to close or open the slot 11 . Two sliding blocks 42 are provided and are located on both sides of the top plate 41. The mounting bracket 52 includes four columns 523 and a mounting plate 524. The four columns 523 are fixed to the main board 51 by screws, and the mounting plate 524 is fixed to the fixing holes in the shell 1 by screws; two guide shafts 522 are provided on the mounting bracket 52, and a guide shaft 522 is installed between the two columns 523. The length direction of the guide shaft 522 is the same as the sliding path direction of the sliding cover assembly 4. The two sliding blocks 42 are respectively slidably connected with the corresponding guide shafts 522 to ensure the sliding stability of the sliding cover assembly 4 and to limit the position of the sliding cover assembly 4; each sliding block 42 is provided with a touch bar 45, one of which is used to touch the on-off switch 61, and the other touch bar 45 is used to touch the high and low beam switching switch 62, so as to realize the separate control of the on-off switch 61 and the high and low beam switching switch 62.

[0046] In this embodiment, in order to ensure the convenience of switching between high and low beams, spring pins 525 are provided on the two columns 523 located at the rear end. After the sliding block 42 drives the touch bar 45 to touch the high and low beam switching switch 62 once, the touch bar 45 is reset to the gap between the on and off switch 61 and the high and low beam switching switch 62 through the spring pins 525.

[0047] The operation process is as follows: the sliding cover assembly 4 slides from the closed state to the open state, and firstly one of the touch bars 45 touches the on / off switch 61, the light source 2 is started, and the lighting device illuminates. At this time, the touch bar 45 is located in the interval between the on / off switch 61 and the high / low beam switching switch 62. When the sliding cover assembly 4 continues to open, the sliding block 42 presses the spring ejector pin 525. At the same time, the touch bar 45 touches the high / low beam switching switch 62 to switch between high beam and low beam. The user cancels the sliding force on the sliding cover assembly 4. After that, the automatic restoring force of the spring ejector pin 525 prompts the sliding cover assembly 4 to slide in the closing direction, and makes the touch bar 45 stay in the gap between the on-off switch 61 and the high- and low-beam switching switch 62. At this time, the lighting device is in the high-beam state or the low-beam state. When the user needs to switch, he only needs to slide the sliding cover assembly 4 in the opening direction. After the high- and low-beam switching is completed, the sliding cover assembly 4 is automatically reset through the spring ejector pin 525, keeping the touch bar 45 in the gap between the on- and low-beam switching switch 61 and the high- and low-beam switching switch 62.

[0048] In order to ensure the stability of the sliding cover assembly 4 staying in the current position (one is in the closed position and the other is in the switching position), a first positioning hole 512 and a second positioning hole 513 are provided on the main board 51 at intervals, and a positioning bead 46 is provided at the bottom of the sliding block 42. The connecting line of the first positioning hole 512 and the second positioning hole 513 is the same as the sliding path, and the positioning bead 46 can be partially inserted into the positioning hole. When the positioning bead 46 is located at the first positioning hole 512, the sliding cover assembly 4 completely closes the notch 11 (i.e., the closed position). When the positioning bead 46 is located at the second positioning hole 513, the touch bar 45 is located in the interval between the on-off switch 61 and the high and low beam switching switch 62 (i.e., the switching position). The positioning hole and the positioning bead 46 cooperate to improve the feel of the sliding cover assembly 4 when it is turned, and to assist in positioning, thereby ensuring that the sliding cover assembly 4 stays stably in the required position.

[0049] In order to facilitate pushing or moving the sliding cover assembly 4, the upper surface of the top plate 41 is convexly provided with anti-skid grooves 44, and the upper surface of the anti-skid grooves 44 is flush with the upper surface of the shell 1, which can effectively prevent the anti-skid grooves 44 from being accidentally moved.

[0050] In this embodiment, the mounting bracket 52 is provided with a receiving port 521 for lifting and installing the display screen button integrated component 5, and the receiving port 521 is a rectangular groove structure, which has a guiding effect on the lifting and lowering of the display screen button integrated component 5; the display screen button integrated component 5 includes: a button bracket 53, the button bracket 53 is also provided with a rectangular groove structure, the button bracket 53 is movably provided with a button module 54 and a display screen 55, the display screen 55 is located above the button module 54, and when the display screen 55 is pressed, the button module 54 can be triggered to switch functions, the display screen 55 is used to display the current performance, mode, power status and other interactive information of the lighting device, and the button module 54 is used to realize the switching between multiple light sources, such as red light, blue light, yellow light, scattered light or concentrated light mode switching. Among them, when the sliding cover component 4 slides open, it drives the button bracket 53 to rise, so that the display screen 55 is displayed, so that the user can perform key operations and view information; when the sliding cover component 4 slides closed, the button bracket 53 automatically descends, thereby driving the display screen 55 to descend and be covered by the top plate 41 of the sliding cover component 4, so as to achieve hiding.

[0051] Specifically, the key module 54 includes: a key plate 541 , a first return spring 542 , a first retaining spring 543 , a mounting column 544 , a pot piece 545 , a switch key 546 , a second return spring 547 , a second retaining spring 548 and a switch column 549 . The mounting post 544 is arranged on the lower surface of the key board 541, and the first return spring 542 is sleeved on the mounting post 544 and the first retaining spring 543 is clamped on the mounting post 544, so as to prevent the first return spring 542 from being separated from the mounting post 544; the main board 51 is provided with a limiting hole 511 for the mounting post 544 to pass through, one end of the first return spring 542 abuts against the lower surface of the main board 51, and the other end abuts against the first retaining spring 543; the pot piece 545 is arranged on the key board 541, the switch post 549 is arranged on the lower surface of the switch button 546, the second return spring 547 is sleeved on the switch post 549 and the second retaining spring 548 is clamped on the switch post 549, and the key bracket 5 3 is provided with a horizontal plate 532, a switch button 546 is located above the horizontal plate 532, a key plate 541 is located below the horizontal plate 532, a through hole 533 is provided on the horizontal plate 532 for the switch column 549 to pass through, the switch column 549 is located just above the pot piece 545, a second clip 548 is located on the lower surface of the horizontal plate 532 and is larger than the through hole 533, which can effectively limit the rising range of the switch column 549, one end of the second return spring 547 abuts against the lower surface of the switch button 546, and the other end abuts against the upper surface of the horizontal plate 532, the display screen 55 is located above the switch button 546, and the display screen 55 and the switch button 546 can move up and down synchronously in the key bracket 53. In this embodiment, the main board 51, the far and near switch circuit board 6 and the key plate 541 are all circuit control boards.

[0052] When the sliding cover assembly 4 slides open and drives the key bracket 53 to rise, since the main board 51 is fixed, the key bracket 53 drives the key board 541 to rise while driving the mounting column 544 to rise. At this time, the first return spring 542 is in a compressed state. After the key bracket 53 rises, the display screen 55 is exposed. When the user presses the display screen 55, the display screen 55 moves downward to drive the switch button 546 to move downward, thereby driving the switch column 549 to move downward. When the switch column 549 moves downward, it presses the pot piece 545. The pot piece 545 presses the switch on the key board 541 to switch between multiple light sources 2. At the same time, when the switch column 549 moves downward, the second return spring 547 is in a compressed state. When the user cancels the pressing force on the display screen 55, the second return spring 547 returns to the initial state, pushing the switch button 546 and the display screen 55 to move upward, so that the switch column 549 is away from the pot piece 545, completing a switching operation. After the switching operation is completed, when the sliding cover assembly 4 slides closed, it cancels the lifting force on the button bracket 53, and the button bracket 53 automatically descends under the elastic force of the first return spring 542 to restore to the initial state, thereby driving the display screen 55 to descend so that the height is located below the lower surface of the sliding cover assembly 4. When the sliding cover assembly 4 is fully closed, the display is located directly below the sliding cover assembly 4 and is hidden.

[0053] In this embodiment, in order to protect the display screen 55, a glass bracket 56 is provided in the button bracket 53 above the display screen 55, and a glass plate 57 is provided on the glass bracket 56. The glass plate 57 is tempered glass. When the user presses the glass plate 57, the glass bracket 56 is driven to move downward. When the glass bracket 56 moves downward, the display screen 55 is driven downward. During the downward movement of the display screen 55, the switch button 546 is driven downward, thereby realizing the pressing action of the switch button 549 on the pot piece 545.

[0054] In order to achieve the sliding of the slide assembly 4 to drive the key bracket 53 to rise or fall, the bottom of each sliding block 42 is fixed with a wedge block 43 by screws, and the two sides of the key bracket 53 are convexly provided with a convex plate, and the lower surface of the convex plate is provided with an inclined surface 531. When the slide assembly 4 is opened, the wedge block 43 contacts and cooperates with the inclined surface 531 to make the key bracket 53 gradually rise, and the first return spring 542 is in a compressed state; when the slide assembly 4 is closed, the wedge block 43 and the inclined surface 531 are gradually separated, and the first return spring 542 is restored to make the key bracket 53 automatically fall. In this way, during operation, the user only needs to slide the slide assembly 4 left and right to realize the appearance or hiding of the display screen 55, and the operation is very simple. Among them, the top plate 41 is slidably arranged on the inner side of the slot 11.

[0055] In this embodiment, for ease of use, a clip 12 is provided on the side of the shell 1 away from the notch 11 , and the clip 12 can be clamped on the brim of the hat, so that it does not need to be held in the hand for use, which is convenient for users.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
