Description

Technical Field

[0001] The invention belongs to the field of portable lighting devices, and in particular relates to a multifunctional combination lamp. Background Art

[0002] Existing multifunctional combination lights generally have multiple lamps, and different lamps have different requirements. For example, the atmosphere lamp needs to change color or switch modes, the illumination lamp needs to control the brightness, and some lamps need to flash at a certain frequency. The compatibility of these different functions requires very complex circuit design. Some functions are difficult to achieve compatibility through a single circuit. If the control circuit and the switch are both set on the lamp head, the cost is high. Each lamp head with different functions needs to be installed with a control circuit, which will take up a lot of space. If there is no single-chip control circuit to achieve different functions, it is generally necessary to set up multiple switches. A single switch cannot achieve complex functions, and multiple switches will also take up a lot of space.

[0003] China Patent Announcement No.: "CN207122787U" Patent Name "Multifunctional Flashlight" Utility Model Patent, its control switch is set on the base, and there is only one plug-in position; similarly, China Patent Announcement No.: "CN209084464U" Patent Name "A Multifunctional Interchangeable Head Work Light" Utility Model Patent, its control switch is also set on the base, and there is only one plug-in position. Although this design is compact in structure, it is difficult to be compatible with too many functions, or different functions need to be realized through more complex circuits. Summary of the invention

[0004] In view of the above-mentioned prior art, an object of the present invention is to provide a multifunctional combination lamp which is more convenient to control and has lower cost.

[0005] The technical solution of the present invention is implemented as follows: a multifunctional combination lamp includes a base and a functional head, a plug-in structure is provided between the functional head and the base, the base is provided with a power supply, the functional head is provided with a plurality of conductive terminals, the base is provided with a plurality of docking terminals, the docking terminals are electrically connected to a control circuit or a power supply, when the functional head is plugged into the base through the plug-in structure, there is at least a first plug-in position and a second plug-in position, when from the first plug-in position to the second plug-in position, at least one conductive terminal or docking terminal changes the electrical connection state and at least one conductive terminal or docking terminal does not change the electrical connection state, and the plug-in structure realizes locking of the plug-in position through the conductive terminal or the docking terminal.

[0006] The beneficial effect of such a design is that the function of the combination lamp can be changed by changing the plug position. Each plug position corresponds to a function, which can reduce the complexity of the control circuit and realize the switching of more functions, especially the control of switching circuit power supply, without too much complicated control, so that the combination lamp can combine more functions. The control switch can be set on the function head, which is more convenient for control. The control circuit can be directly set on the base, which can further reduce the volume of the function head and make the overall design more compact. The conductive terminal or the docking terminal has a locking function, and there is no need to set other locking structures, which simplifies the structure of the product. Conductive terminals and docking terminals are provided at multiple plug positions to meet the needs of locking at different plug positions.

[0007] Furthermore, the plug-in structure includes a male end and a female end, which are respectively fixed to the base and the functional head. The male end includes a columnar portion and an ear portion. The columnar portion is cylindrical and located at the center of one end of the base or the functional head. The ear portion is located on the side of the columnar portion and is locally protruded by a certain height relative to the side of the columnar portion. The female end includes a hole portion and a clamping portion. The hole portion is provided with a circular cavity to accommodate the male end. The clamping portion is located on the inner wall of the circular cavity and is locally protruded relative to the circular cavity. In this way, when the functional head needs to be combined with the base, the ear portion of the male end and the clamping portion of the female end are first inserted in an offset manner, and then the male end is rotated relative to the female end so that the clamping portion abuts against the ear portion to limit the male end from being separated from the female end. In this way, the male end and the female end can be connected together, and have a limiting function in both the axial and radial directions, thereby fixing the base and the functional head together.

[0008] Furthermore, further, the butt terminal or the conductive terminal abuts against the elastic member so that the butt terminal and the conductive terminal are electrically connected under the action of the elastic member, and such a design of the butt terminal and the conductive terminal has better electrical connection performance.

[0009] Furthermore, a recessed hole is provided at the matching position corresponding to the docking terminal or the conductive terminal so that the docking terminal or the conductive terminal can be inserted into the recessed hole under the elastic force of the elastic member to form a lock to prevent the male end from rotating relative to the female end. The locking function is realized directly by using the terminal, which has a simple structure and a better locking effect. Compared with the prior art, a larger force is required to achieve the separation of the plug-in structure. The terminal locking makes the connection more stable and improves the reliability of field use.

[0010] Furthermore, the male end and the female end have different locking positions so that different docking terminals can be electrically connected to the conductive terminals by adjusting the locking position. In this way, the working mode of the functional head can be adjusted by the locking position. For multi-color ambient lights, the color of the light can be adjusted by adjusting the locking position. In this way, the function selection can be realized when the lamps are combined, making it more convenient and quick to use.

[0011] Furthermore, the docking terminal includes a center terminal, a switch terminal and a surround terminal. The center terminal is located at the center position, and the switch terminal and the surround terminal are arranged on the periphery of the center terminal. The center terminal is located at the center position and is less affected by the rotation. The switch terminal and the surround terminal are set at non-center positions and the connectivity state of the terminal can be controlled by rotation, that is, the switch and the terminal are combined into one, making the control more convenient. The ring terminal can also be set to match it so that it is always in an electrically connected state during the rotation process.

[0012] Furthermore, the multifunctional combination lamp comprises at least a lighting lamp combination, an atmosphere lamp combination and an electric fan combination, so that it can be conveniently used for camping and has the functions of lighting, rendering atmosphere and cooling down.

[0013] Furthermore, the docking terminal or the conductive terminal is provided with a moving mechanism, which can unlock the male end and the female end by moving the docking terminal or the conductive terminal, and this arrangement makes unlocking more convenient.

[0014] Furthermore, the conductive terminal includes a centering terminal, a half-ring terminal, a first terminal, a second terminal and a third terminal. The centering terminal is connected to the center terminal, the half-ring terminal is connected to the switch terminal, and the surrounding terminal is connected to the first terminal, the second terminal and the third terminal respectively when in different positions. In this way, different terminals of the surrounding terminal can be connected according to different functional requirements.

[0015] Furthermore, the mating surface of the semi-ring terminal is in the shape of a semicircular ring or a small semi-circular ring. The semi-ring terminal is designed to be in the shape of a semicircular ring so that the male end can always maintain electrical connection when rotating relative to the female end within a certain range. The mating surfaces of the first terminal, the second terminal and the third terminal are provided with recessed holes so that the surrounding terminal can be inserted into the recessed holes to achieve locking when mating with the first terminal, the second terminal and the third terminal. The design of the recessed holes can achieve locking functions at different positions, making the terminal connection more stable and less prone to accidental power outages.

DETAILED DESCRIPTION

[0038] As required, detailed embodiments of the present invention are disclosed herein, but it should be understood that the disclosed embodiments are merely exemplary of the present invention, and the present invention may be implemented in different and alternative forms. The accompanying drawings may not be drawn to scale, and certain features may be exaggerated or reduced to show the details of specific components. Therefore, the specific structural and functional details disclosed herein should not be understood as having a limiting meaning, but only as a representative basis to teach those skilled in the art to adopt the present invention differently. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a multifunctional combination lamp includes a base 1 and a functional head 2, a plug-in structure is provided between the functional head 2 and the base 1, the base 1 is provided with a power supply 4, i.e., a battery, the functional head 2 is provided with a control switch 3, the functional head 2 is provided with a plurality of conductive terminals 7 and at least one conductive terminal 7 is electrically connected to the control switch 3, the base 1 is provided with a plurality of docking terminals 6, the docking terminals 6 are electrically connected to the control circuit or the power supply 4, when the functional head 2 is plugged with the base 1 through the plug-in structure 5, there is at least a first plug-in position and a second plug-in position, when from the first plug-in position to the second plug-in position, at least one conductive terminal 7 or docking terminal 6 changes the electrical connection state, and the conductive terminal 7 located in the center does not change the electrical connection state, and the plug-in structure 5 realizes the locking of the plug-in position through the conductive terminal 7 or the docking terminal 6.

[0040] like Figure 1As shown, the combination is a lighting combination, the functional head 2 has a focusing function, and the whole is relatively large. For easy use, the functional head 2 of the lighting combination is provided with a handle 90, and a press control switch 3 is provided on the handle 90 for convenient control of the lighting, and the base 1 is provided with a charging interface and a discharging interface. The lighting needs strong light, normal light and weak light modes, and some lighting can also be turned on to flash intermittently at a certain frequency in order to transmit signals.

[0041] like Figure 2 As shown, the combination is an atmosphere light combination. The outer shell of the base 1 is provided with a non-slip lining 93. The atmosphere light has a monochrome mode and an automatic color switching mode. The automatic color switching needs to be realized using a control circuit. The monochrome mode maintains a single color, and different single color light sources can be lit by switching different circuits.

[0042] like Figure 3 As shown, the combination is a hanging lamp combination, and the base 1 can be selected to be a lighter base 1, which is easier to use and can be used as temporary lighting or have the function of an atmosphere lamp.

[0043] like Figure 4 As shown, the combination is an electric fan combination, and the speed of the electric fan can be easily controlled by switching the circuit, that is, the speed of the fan can be controlled by connecting different conductive terminals 7 and connecting terminals 6.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the plug-in structure 5 includes a male end 51 and a female end 52, which are fixed to the base 1 and the functional head 2 respectively. The male end 51 includes a columnar portion 53 and an ear portion 54. The columnar portion 53 is cylindrical and located at the center of one end of the base 1 or the functional head 2. The ear portion 54 is located on the side of the columnar portion 53 and locally protrudes a certain height relative to the side of the columnar portion 53. The female end 52 includes a hole portion 55 and a clamping portion 56. The hole portion 55 is provided with a circular cavity 57 to accommodate the male end 51. The clamping portion 56 is located on the inner wall of the circular cavity 57 and is locally protruded relative to the circular cavity 57. Grooving on the side of the columnar portion 53 can replace the locally protruding ear portion 54. Although the groove is more wasteful of materials than setting the ear portion 54, it should be regarded as an equivalent design to achieve the same plug-in function.

[0045] like Fig.21 As shown, the combination lamp can use a single-button multi-speed dimming circuit to realize the control of different functions of the combination lamp, wherein the position of the LED lamp can be changed to other structures according to functional requirements. For example, when an electric fan is used, it can be a motor, and PWM dimming can also be used to control the motor, and a SOT23-6 chip can be used.

[0047] like Figure 5-13 As shown, the butt terminal 6 or the conductive terminal 7 abuts against the elastic member 58 so that the butt terminal 6 and the conductive terminal 7 are electrically connected under the action of the elastic member 58. Preferably, the conductive terminal 7 can be set as a stepped shaft, and the spring sleeve is arranged outside one end of the conductive terminal 7 and abuts against the stepped surface 59 of the conductive terminal 7, so that the conductive terminal 7 can achieve expansion and contraction within a certain range.

[0048] like Figure 7 and Figure 8 As shown, a concave hole 60 is provided at the matching position corresponding to the docking terminal 6 or the conductive terminal 7 so that the docking terminal 6 or the conductive terminal 7 is inserted into the concave hole 60 under the elastic force of the elastic member 58 to form a lock to prevent the male end 51 from rotating relative to the female end 52. After the male end 51 is inserted into the female end 52 and rotated a certain angle, it can be locked in the axial and radial directions, but there is no locking structure in the circumferential direction. The use of the terminal to achieve the locking function simplifies the overall structure and reduces the production cost. Preferably, the docking end of the conductive terminal 7 is designed to be a cylindrical structure, and a concave hole 60 is provided on the docking terminal 6 to match the docking end of the conductive terminal 7 so that the docking end can be inserted into the concave hole 60.

If multiple terminals are provided and some terminals are in a non-working state, the non-working terminals can also be used to achieve the locking function.

[0049] like Figure 7-13 As shown, the docking terminal 6 or the conductive terminal 7 is provided with a moving mechanism 8 that can unlock the male end 51 and the female end 52 by moving the docking terminal 6 or the conductive terminal 7.

[0051] like Fig.12As shown, the moving mechanism 8 is set in a fork shape, including a fork 81 and a rod 82. The number of forks is the same as the number of conductive terminals 7 that need to be moved. If there are two conductive terminals 7, a U-shaped fork 81 can be set. The front end 83 of the fork 81 is provided with an inclined surface or an arc surface that abuts against the abutment portion 79 of the conductive terminal 7, which can guide the conductive terminal 7 to move in the vertical direction when the fork 81 moves in the horizontal direction. The rod 82 is fixed to the head shell 85 in a sliding manner relative to the head shell 85 through a positioning block 84. The rear end of the rod 82 is connected to a flexible button 86 fixed to the head shell 85. The flexible button 86 has a certain elasticity and can drive the moving mechanism 8 to reset. The rod 82 can be adjusted according to the position of the flexible button 86 and the fork 81, and can be set to various curved shapes according to the specific space, so as to avoid affecting the setting of other structures. The center of the flexible button 86 is provided with a fixing hole 89 to fix the rod 82, and the flexible button 86 is provided with a fixing groove 94, which can be installed to the mounting hole of the head shell 85 through the fixing groove.

[0052] Embodiment 2:

[0053] like Fig.14 and Fig.15 As shown, part of the conductive terminal 7 is installed on the head shell 85 of the functional head 2 in a manner that it can be moved in the horizontal direction.

A recessed hole 60 is set on the docking terminal 6 so that the conductive terminal 7 can achieve a locking function when the docking terminal 6 is inserted. The stepped portion of the conductive terminal 7 abuts against the front fork 88 of the moving mechanism 8. The moving mechanism 8 is connected to the flexible button 86 through a connecting rod 87 so that pressing the flexible button 86 can move the conductive terminal 7 to achieve an unlocking function. The conductive terminal 7 can also be set to a structure that moves along an inclined direction, and movements in different directions are regarded as equivalent designs.

[0054] Embodiment 3:

[0055] like Fig.16 As shown, the male end 51 and the female end 52 have different locking positions so that different electrical connections between the docking terminal 6 and the conductive terminal 7 can be achieved by adjusting the locking positions. The male end 51 is located on the functional head 2, and the female end 52 is located on the base 1.

[0056] like Fig.16 As shown, the docking terminal 6 includes a central terminal 61 , a switch terminal 62 and a surrounding terminal 63 . The central terminal 61 is located at a central position, and the switch terminal 62 and the surrounding terminal 63 are circumferentially arranged around the central terminal 61 .

[0059] like Fig.16 As shown, the switch terminal 62 and the surrounding terminal 63 are in contact with the spring to realize the telescopic function. The moving structure of the docking terminal 6 is designed with reference to the moving mechanism 8 in Example 2, that is, the unlocking is realized by the moving mechanism 8, and the locking function is realized by the elastic member 58, that is, after the position is aligned, the elastic member 58 pushes the docking terminal 6 to move to the concave hole 60 to realize locking. After the male end 51 is inserted into the female end 52, when it is rotated, the first terminal 73 is docked with the surrounding terminal 63 at the first position, and the switch terminal 62 is docked with the semi-ring terminal 72.

After being unlocked by the moving mechanism 8, it is rotated to other required positions.

[0060] Embodiment 4:

[0061] like Fig.17 As shown, this embodiment is similar to Embodiment 3, but the arrangement of the terminals is different. The first terminal 73, the second terminal 74 and the third terminal 75 are respectively arranged on both sides. After the male end 51 is inserted into the female end 52, directly and slowly rotating clockwise can lock the surrounding terminal 63 with the first terminal 73, and slowly rotating counterclockwise can lock the surrounding terminal 63 with the second terminal 74. After unlocking by the moving mechanism 8, it can be rotated to the locking state of the surrounding terminal 63 and the third terminal 75. This design of forward and reverse rotation can realize different functions and is very convenient to use. If more functions are required, more locking positions can be set in clockwise and counterclockwise rotation.

The recessed hole 60 is set with reference to other embodiments. The first terminal 73, the second terminal 74 and the third terminal 75 can realize the locking function with any recessed hole 60.

Seven colors can appear in seven positions. The interval terminal 65, the first ring terminal 66, the second ring terminal 67 and the third ring terminal 68 can be connected to the same wire and have the same potential. Different wires can also be connected as needed to achieve more functions. In this way, different functions can be achieved by rotating the male end 51 relative to the female end 52 to different positions. The conductive terminal 7 and the docking terminal 6 have 7 docking positions, and a rotation position mark is provided on the head shell 85 of the functional head 2 or the outer shell of the base 1, which can achieve at least 7 functions.
