[0001] This utility model relates to the field of lamp holder design technology, and in particular to a lamp holder device with a switch. Background Technology

[0002] Currently, with the continuous changes in market demand, external auxiliary devices such as head-mounted battery compartments not only need normal auxiliary power supply functions, but some also require lighting.

[0003] However, many current lamp head designs cannot control the on and off of the light, resulting in the light being constantly on. This means that the lamp head will remain on when the light is not needed, thus having the opposite effect. Furthermore, the constantly on lamp head will increase the power consumption of the entire external device.

[0004] Therefore, how to provide a lamp holder that can be turned on or off is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0045] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0047] The purpose of this invention is to provide a lamp holder device with a switch, which can control the lighting of the lamp holder by means of a switch knob on the lamp holder. Users can control the lighting according to their needs, turning on the lighting when needed and turning it off when not needed, thus without increasing power consumption.

[0048] To achieve the above objectives, the present invention provides the following technical solution:

[0049] Please see Figures 1 to 5 This embodiment provides a lamp holder device with a switch, including: a cylindrical body 100, a light-emitting component 200, positive and negative electrode components, and a control component 500; the cylindrical body 100 is a cylindrical structure, and a rotatable switch knob 110 is sleeved on its outer periphery; the light-emitting component 200 is installed at one end inside the cylindrical body 100 and is used to emit light after being powered on; the positive and negative electrode components are installed at the other end inside the cylindrical body 100, and the positive and negative electrode components include a positive electrode component 300 and a negative electrode component 400, which are insulated and isolated from each other by a first gasket 710. The positive and negative electrode components are used to connect the power supply and supply power to the light-emitting component 200; the control component 500 is installed inside the cylindrical body 100 and is located between the light-emitting component 200 and the positive and negative electrode components. The control component 500 connects the light-emitting component 200 and the positive and negative electrode components, and the control component 500 can turn the light-emitting component 200 on or off as the switch knob 110 is rotated.

[0050] Specifically, the cylindrical body 100 is the main body of the lamp holder device, which supports other components. The cylindrical body 100 has a cylindrical structure, and a switch knob 110 is sleeved in the middle of its outer peripheral wall. Inside the cylindrical body 100, a light-emitting component 200, a control component 500, and positive and negative electrode components are installed in sequence, wherein the positive and negative electrode components include a positive electrode component 300 and a negative electrode component 400. In this embodiment, in order to facilitate the installation of the light-emitting component 200, a partition is provided in the middle of the inside of the cylindrical body 100. The light-emitting component 200 is installed on one side of the partition, while the control component 500 and the positive and negative electrode components are installed on the other side of the partition. This also avoids the heat generated by the light-emitting component 200 during operation from affecting the operation of the control component 500.

[0051] The positive electrode assembly 300 and the negative electrode assembly 400 are respectively connected to the positive and negative terminals of the power supply, and are insulated from each other by a first point to prevent short circuits. Both the positive electrode assembly 300 and the negative electrode assembly 400 are connected to the control assembly 500, which in turn is electrically connected to the light-emitting assembly 200. The light-emitting assembly 200 acts as an actuator, emitting light when powered on. The control assembly 500 is positioned between the positive and negative electrode assemblies and the light-emitting assembly 200, functioning as a switch to control the circuit's conduction or deactivation, thereby controlling the operation of the light-emitting assembly 200. It should be noted that the switch knob 110 in this application is rotatably mounted on the outer periphery of the cylinder body 100, and the switch knob 110 cooperates with the control assembly 500. When the switch knob 110 is rotated at a certain angle, the control assembly 500 will conduct or deactivate the circuit, thus controlling the operation of the light-emitting assembly 200. With this configuration, the operator can turn the switch knob 110 to turn the lamp head device on or off.

[0052] Preferably, the light-emitting component 200 includes: a light panel with a light strip 210 and a light cup 220; the light panel with a light strip for emitting light is provided in the middle of the light panel with a light strip; the light cup 220 is a conical cylindrical structure, and its smaller diameter end is installed on the light panel with a cup holder 230 and is sleeved on the outer periphery of the light strip. The light cup 220 is used to reduce light loss of the light strip and improve light efficiency.

[0053] Specifically, such as Figure 2 and Figure 3 As shown, the light panel strip 210 also adapts to the shape of the cylindrical body 100, and is a circular plate structure. A light strip that can emit light for illumination is set at the center of the plate. Furthermore, in order to prevent the light emitted by the light strip from scattering and causing poor lighting effect, a light cup 220 with a conical cylindrical structure is provided around the circumference of the light strip. The inner wall of the light cup 220 is a smooth surface that can reflect light. Its smaller diameter end can be installed on the light panel strip 210 through the cup holder 230. The light panel strip 210 is installed on the partition set inside the cylindrical body 100.

[0054] Preferably, the control component 500 includes: a switch control board 510, a first Hall switch 520, a second Hall switch 530, and a magnet 540; the switch control board 510 is installed inside the cylinder body 100 and is connected to the lamp panel 210 via a cable; the positive electrode component 300 and the negative electrode component 400 are both electrically connected to the switch control board 510; the first Hall switch 520 is used to control the circuit of the switch control board 510 to be turned on, so that the lamp panel 210 is activated; the second Hall switch 530 is used to control the circuit of the switch control board 510 to be turned off, so that the lamp panel 210 is turned off; the magnet 540 is installed on the inner wall of the switch knob 110 and the outer wall of the cylinder body 100, and it can rotate synchronously with the switch knob 110; the magnet 540 is used to trigger the first Hall switch 520 or the second Hall switch 530 when the switch knob 110 is rotated.

[0055] Specifically, such as Figures 2 to 5 As shown, the switch control board 510 in this embodiment is also a circular plate structure, which is installed on the lower side of the partition inside the cylinder 100, and two Hall elements are welded to its edge; when the first Hall switch 520 is triggered, the switch control board 510 will conduct the circuit between the positive and negative electrode components and the light-emitting component 200, thereby realizing illumination; when the second Hall switch 530 is triggered, the switch control board 510 will disconnect the circuit between the positive and negative electrode components and the light-emitting component 200, thereby turning off the lamp head device; it can be understood that both the first Hall switch 520 and the second Hall switch 530 can be triggered by the magnet 540. Therefore, in this embodiment, a magnet 540 is fixedly installed in the magnet 540 slot on the inner side wall of the switch knob 110. When the switch knob 110 is rotated, the magnet 540 will rotate accordingly. When the magnet 540 moves to a position close to the first Hall switch 520, specifically as follows... Figure 4 As shown, at this time, the switch control board 510 is turned on, and the lamp holder device starts to illuminate. When the switch knob 110 is rotated further, the magnet 540 moves to the position of the second Hall switch 530, which triggers the second Hall switch 530, thereby turning off the lamp holder device. Specifically, as shown... Figure 5 As shown; with this setup, the lamp holder can be turned on and off by rotating the switch knob 110.

[0056] Preferably, the positive electrode assembly 300 is installed inside the cylinder body 100, and includes a copper ring 310 and two first contacts 320 vertically connected to the copper ring 310. The ends of the first contacts 320 away from the copper ring 310 are welded to the switch control board 510.

[0057] In this embodiment, the lamp holder is mounted on an external auxiliary device such as a head-mounted battery compartment, and its positive and negative electrode components are connected to the externally mounted battery compartment. The positive electrode component 300 in this embodiment includes a ring-shaped copper ring 310 and two first contacts 320 vertically connected to the copper ring 310. The ends of the first contacts 320 are soldered to the switch control board 510, and the copper ring 310... Figure 3 As shown, its outermost bottom ring will be exposed and will be connected to the positive terminal of the external device.

[0058] Furthermore, the negative electrode assembly 400 includes a stud 410 and a second spring 420 disposed inside the stud 410. The stud 410 is threaded to the end of the cylinder 100 away from the light-emitting assembly 200. The second contact 430 of the second spring 420 passes through the stud 410 and the copper ring 310 and is connected to the switch control board 510.

[0059] The negative electrode assembly 400 is installed at the bottom of the lamp holder assembly. When the lamp holder assembly is installed on an external device, it will be connected to the battery compartment. Therefore, the negative electrode assembly 400 in this embodiment includes a stud 410, a second spring 420, and a second contact 430. The stud 410 has a stepped structure, with its smaller diameter end threaded to the inner wall of the lower end of the cylinder 100, while the larger diameter end is threaded to the inner wall of the battery compartment of the external device. Both the second spring 420 and the stud 410 are made of conductive metal and are welded together. The second spring 420 can abut against the battery in the battery compartment of the external device to limit the battery position. In order to ensure stable contact position and avoid damage to the lamp holder assembly due to poor contact, the center of the second spring 420 is also connected to the switch control board 510 through the second contact 430. The second contact 430 passes through the copper ring 310 and is directly welded to the switch control board 510. With this configuration, the negative electrode component 400 serves as both the negative electrode of the lamp holder and the negative electrode of the external device. When the lamp holder is in the off state, the lamp lighting is off, and the stud 410 of the lamp holder is connected to the negative electrode of the external device. In other words, the lamp holder acts as the negative electrode of the entire device, supplying power to the entire device without increasing power consumption. When the lamp holder is in the on state, the lamp lighting is on, and the lamp holder not only acts as the negative electrode of the entire device but also provides illumination.

[0060] Preferably, the side wall of the cylinder body 100 is provided with a positioning pin 120 along its radial direction, and the inner side wall of the switch knob 110 is provided with a travel groove 111 that cooperates with the positioning pin 120. The positioning pin 120 is engaged in the travel groove 111 to limit the rotation angle of the switch knob 110.

[0061] Understandably, in order to quickly and conveniently turn the lighting on or off, this embodiment limits the rotation angle of the switch knob 110; specifically, as shown in... Figure 4 and Figure 5 As shown, a protruding positioning pin 120 is installed on the side wall of the cylinder body 100. At the same time, a concave end blocking travel groove 111 is provided on the inner side wall of the switch knob 110. The positioning pin 120 can move within the travel groove 111, but the positioning pin 120 cannot disengage to form the groove.

[0062] like Figure 4 As shown, when the switch knob 110 is in the open position, the magnet 540 corresponds to the first Hall switch 520, and the positioning pin 120 is exactly at the leftmost end of the travel groove 111. Therefore, the switch knob 110 cannot continue to rotate clockwise. Figure 5 As shown, when the switch knob 110 is in the off position, the magnet 540 corresponds to the second Hall switch 530, and the positioning pin 120 is located at the rightmost end of the travel groove 111. In this way, the switch knob 110 can no longer be rotated counterclockwise. This setting allows the switch knob 110 to rotate only within a specified range, improving the convenience of opening or closing the lamp holder.

[0063] Preferably, the side wall of the cylinder 100 is further provided with an elastic limiting component along its radial direction. The elastic limiting component includes a first spring 130 radially disposed on the cylinder 100 and a steel ball 140 installed at the end of the first spring 130. The first spring 130 always tends to push the steel ball 140 away from the cylinder 100. The inner side wall of the switch knob 110 is provided with two limiting grooves 112. The two limiting grooves 112 are respectively used to engage with the steel ball 140 when the magnet 540 triggers the first Hall switch 520 or the second Hall switch 530, so as to limit the rotation of the switch knob 110.

[0064] Understandably, in order to ensure that the switch knob 110 remains stable when rotated to the open or closed position, i.e., to prevent the switch knob 110 from deviating from the preset position after being rotated to the correct position, this embodiment has a radially extending blind hole on the outer wall of the cylinder body 100, and a first spring 130 is installed in the blind hole. A steel ball 140 is installed at the top of the first spring 130. When the switch knob 110 is in the installed state, the switch knob 110 will press against the steel ball 140 and compress the first spring 130. At the same time, the inner wall of the switch knob 110 is aligned with the first Hall effect sensor corresponding to the magnet 540. The positions of switch 520 and the second Hall switch 530 are respectively provided with arc-shaped limiting grooves 112. In this way, when the switch knob 110 is rotated, and the magnet 540 triggers the positions of the first Hall switch 520 and the second Hall switch 530, the steel ball 140 will move outward precisely to the limiting groove 112 under the action of the first spring 130. At this time, the switch knob 110 will not shake randomly due to the limiting effect of the first spring 130 and the steel ball 140, thus fixing the switch knob 110. It will only continue to rotate when it is twisted by an external force, thereby switching the state.

[0065] Preferably, the end of the cylinder 100 away from the positive and negative electrode assembly is fitted with a housing 600, which is threaded to the side wall of the cylinder 100 and is used to fix the protective glass 610 to the end face of the photocell 220.

[0066] Understandably, in order to protect the light-emitting component 200 from damage, a protective glass 610 is attached to the end face of the light cup 220. In this embodiment, the protective glass 610 is fixed to the top of the light cup 220 by the outer shell 600, specifically as follows: Figure 2 and Figure 3 As shown; in addition, the lamp housing also has the function of limiting the movement of the switch knob 110 along the axis of the cylinder body 100.

[0067] Preferably, a sealing ring 720 is provided between the outer casing 600 and the protective glass 610, a second gasket 730 is provided between the protective glass 610 and the light cup 220, and a third gasket 740 is installed between the outer casing 600 and the switch knob 110.

[0068] Similarly, to prevent water from entering the lamp holder, a sealing ring 720 is filled between the outer casing 600 and the protective glass 610. The sealing ring 720 also has a buffering effect to prevent the outer casing 600 from damaging the protective glass 610 during installation. Likewise, to prevent the light cup 220 from damaging the protective glass 610 when it comes into contact with it, a second gasket 730 is installed between their ends. At the same time, to prevent severe wear between the outer casing 600 and the switch knob 110, a second gasket 730 is also installed between them.

[0069] Preferably, the switch knob 110 has several rotating protrusions evenly distributed on its outer periphery.

[0070] Understandably, this design makes it easier for operators to apply force to the switch knob 110 and reduces the likelihood of slippage.

[0071] In summary, this application provides a lamp holder device with a switch, the specific assembly steps of which are as follows: First, fix the switch control board 510 on the cylindrical body 100, then assemble the positive electrode component 300, the third gasket 740 and the negative electrode component 400 in sequence, wherein the negative electrode component 400 is fixed to the cylindrical body 100 by threads; then assemble the lamp plate with lamp 210, the reflector 220 holder, the reflector 220, the second gasket 730, the protective glass 610 and the sealing ring 720 in sequence; install the positioning pin 120, the first spring 130 and the steel ball 140 on the cylindrical body 100, install the magnet 540 on the switch knob 110 and assemble it on the cylindrical body 100; then install the third gasket 740 and the outer shell 600 in sequence, wherein the outer shell 600 is fixed to the cylindrical body 100 by threads.
