Description

Technical Field

[0001] The present invention relates to the field of lamps, and particularly to a folding work lamp, a folding method thereof and a self-locking method thereof. Background Art

[0002] Existing work lamps are divided into fixed lighting lamps and mobile lighting lamps. For fixed lighting lamps, they are suitable for use in specific lighting sites, such as wall lamps fixed on walls or ceiling lamps installed on ceilings. Generally, such lamps are relatively large in size, have relatively high brightness, and can illuminate a relatively wide range. However, the disadvantage of such fixed lighting lamps is that it is difficult to move them according to the needs of the staff. The characteristics of mobile lighting lamps are opposite to those of fixed lighting lamps. For example, a flashlight lamp. Among them, mobile lighting lamps are small in volume, suitable for carrying, and can be placed at a specific angle according to the use location to illuminate small corner areas. However, it is very difficult for the existing mobile lighting lamps with small size to achieve large-range lighting. Therefore, users need to often move the lamps during use. If the size is large, it is difficult to carry. Therefore, most of the existing mobile work lamps have at least one of the following defects: First, some existing work lamps are relatively large in volume, making them difficult to carry and store; Second, some existing work lamps are relatively small in volume, with a small lighting range, and need to constantly move positions during the use of the lamps, making the use operation inconvenient; Third, the existing work lamps are not convenient to fix during use, and can only adapt to specific installation positions. Once the use environment changes, it is difficult to maintain the fixed position of the lamps; Fourth, the lighting angle of the existing work lamps is fixed with the installation position of the lamps and is difficult to adjust; Fifth, improper storage of the existing work lamps after use is likely to cause damage to the lamps, affecting future use.

[0003] With the development of the economy, there are more and more vehicles such as cars and electric vehicles, which also facilitate people's travel. However, vehicle maintenance and inspection are becoming more and more important for car owners and maintenance personnel. The parts under the engine hood of the vehicle need to be frequently inspected and maintained. During the inspection process, an engine inspection lamp is usually required for lighting. The existing fixed lamps cannot meet the user's needs, and it is difficult to illuminate specific positions under the engine hood. When moving the lamp, due to the small lighting range, it is necessary to constantly move the position. If it is too large, it is difficult to carry in the vehicle, and the lamp is also difficult to store and put away. Summary of the Invention

[0083] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present invention.

[0084] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are 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. Therefore, the above - mentioned terms should not be construed as limiting the present invention.

[0085] It is understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of an element may be one, while in other embodiments, the number of the element may be multiple. The term "a" should not be construed as a limitation on the quantity.

[0086] Referring to the accompanying drawings of the present invention Figures 1 to 20 As shown, a folding work lamp according to a first preferred embodiment of the present invention is illustrated in the following description. The folding work lamp includes at least two lamp body units 10 and at least one pivoting device 20, wherein the lamp body units 10 are arranged on the pivoting device 20, supported by the pivoting device 20 and connected to the lamp body units 10, and the pivoting device 20 allows the lamp body units 10 to rotate based on the pivoting device 20, so that the folding work lamp has a folded state and an unfolded state and can switch between the folded state and the unfolded state.

[0087] As an example, when the number of the lamp body units 10 is three and the number of the pivoting devices 20 is two, the lamp body units 10 and the pivoting devices 20 are arranged in sequence and alternately, that is, the same pivoting device 20 connects two of the lamp body units 10. Those skilled in the art can understand that in other alternative embodiments of the present invention, the number of the lamp body units 10 may be two and the number of the pivoting devices 20 may be one; or the number of the lamp body units 10 may be four and the number of the pivoting devices 20 may be three. In the preferred embodiment of the present invention, the number of the lamp body units and the pivoting devices 20 of the folding work lamp is not limited.

[0088] As Figure 1As shown, when the folding work lamp is in the unfolded state, two of the lamp body units 10 connected to the same pivot device 20 are arranged at both ends of the pivot device 20, that is, the pivot device 20 is connected and supports the lamp body units 10 in two opposite directions, so that the two lamp body units 10 extend in opposite directions from both sides of the pivot device 20, increasing the illumination range of the folding work lamp. It is worth mentioning that the unfolding angle α between the two lamp body units 10 connected to the pivot device 20 and the pivot device 20 is set. Preferably, when the folding work lamp is in the fully unfolded state, α can reach 180°, that is, when the folding work lamp is fully unfolded, two or more of the lamp body units 10 of the folding work lamp are in the same plane, maximizing the illumination range of the lamp body units 10 of the folding work lamp. Preferably, in this preferred embodiment of the present invention, the illumination directions of the lamp body units 10 of the folding work lamp are the same, that is, when the folding work lamp is completely in the unfolded state, each of the lamp body units 10 irradiates in the same direction (the X direction in the figure). Those skilled in the art can understand that when the folding work lamp is unfolded from the folded state to the unfolded state, the lamp body units 10 of the folding work lamp are opened and suitable for lighting.

[0089] As Figure 2 shown, when the folding work lamp is in the folded state, the two lamp body units 10 are located on the same side of the pivot device 20 and overlap each other, so that the overall length of the folding work lamp is reduced, which is beneficial to the storage of the folding work lamp and saves the storage space of the folding work lamp. It is worth mentioning that when the folding work lamp is in the fully folded state, the unfolding angle α between the two lamp body units 10 connected to the pivot device 20 and the pivot device 20 can be as small as 0°. When the folding work lamp is fully folded, the two lamp body units 10 connected to the same pivot device 20 are folded forward (the Y direction in the figure) and / or folded backward (the opposite direction of the Y direction in the figure) on the same side of the pivot device 20 to minimize the lamp body length of the folding work lamp, suitable for storage and accommodation.

[0090] It can be understood that in this preferred embodiment of the present invention, when the folding work lamp is switched from the folded state to the unfolded state, the unfolding angle α between the two lamp body units 10 connected to the pivot device 20 and the pivot device 20 ranges from 0° to 180°, that is, the flipping angle of the pivot device 20 is between 0° and 180°.

[0091] The folding work lamp further includes two locking devices 30, wherein the locking devices 30 are disposed at the ends of the lamp body unit 10, and the locking devices 30 are pivotable to allow the locking devices 30 to pivotally switch between a locking position 301 and at least one unlocking position 302.

[0092] As Figure 3 shown, the folding work lamp is in the folded state, and when the locking device 30 is rotated to the unlocking position 302, the folding work lamp is in the unlocked state, allowing the folding work lamp to be unfolded from the folded state to the unfolded state. As Figure 4 shown, the folding work lamp is in the folded state, and when the locking device 30 is rotated to the locking position 301, the folding work lamp is in the locked state, and the locking device 30 buckles the lamp body unit 10 on the pivoting device 20 to prevent the lamp body unit 10 from being unfolded. The locking device 30 of the folding work lamp is telescopically disposed on the lamp body unit 10, and the locking device 30 can extend outward from the end of the lamp body unit 10 to extend the overall length of the folding work lamp. It is worth mentioning that when the folding work lamp is in the unfolded state or the board unfolded state, the locking device 30 can be hung or hooked on a hooked object, such as the hood of a vehicle.

[0093] The locking device 30 is further provided with at least one locking space 300, wherein in the locked state, the locking space 300 of the locking device 30 is adapted to accommodate the pivoting device 20, and when the folding work lamp is suspended for use, the locking device 30 is adapted to hook the attached object on the locking space 300.

[0094] As Figure 5 and Figure 6 shown, when the folding work lamp is in the unfolded state, it can be hung on both sides of the hooked object, wherein the locking device 30 of the folding work lamp can extend outward from both ends of the lamp body unit 10 to adjust the length of the folding work lamp to adapt to hooked objects of different widths, such as the hood of a vehicle. When the folding work lamp is in the semi-unfolded state, one of the locking devices 30 of the folding work lamp is rotated to the unlocking position 302 to allow the folding work lamp to be suspended on the hood of the vehicle.

[0095] It is worth mentioning that when the folding work lamp is in the folded state, by rotating the locking device 30 to the locking position 301, the pivoting device 20 is hooked by the locking device 30 in the hanging space 300 of the locking device 30, that is, the locking device 30 of the folding work lamp locks the pivoting device 20 and the lamp body unit 10 to achieve self-locking of the folding work lamp. As Figure 7 shown, the lamp body unit 10 of the folding work lamp includes a first lamp body unit 10a, a second lamp body unit 10b and a third lamp body unit 10c. The pivoting device 20 further includes a first pivoting device 20a and a second pivoting device 20b. The first lamp body unit 10a and the second lamp body unit 10b are arranged on the first pivoting device 20a, and the second lamp body unit 10b and the third lamp body unit 10c are arranged on the second pivoting device 20b. The lamp body unit 10 has a light emitting surface 101 and a backlight surface 102. The lamp body unit 10 projects light outward from the light emitting surface 101, and the backlight surface 102 faces away from the light emitting surface 101 of the lamp body unit 10, that is, the light emitting surface 101 and the backlight surface 102 of the lamp body unit 10 are arranged back to back. Preferably, in this preferred embodiment of the present invention, the light emitting surfaces 101 of the first lamp body unit 10a, the second lamp body unit 10b and the third lamp body unit 10c are parallel to each other (in the X-axis direction in the figure), that is, when the folding work lamp is in the unfolded state, the light irradiation directions of the lamp body units 10 are parallel to each other.

[0096] It is worth mentioning that in this preferred embodiment of the present invention, the structures of the first lamp body unit 10a, the second lamp body unit 10b and the third lamp body unit 10c of the lamp body unit 10 are substantially the same. The following further describes the structure and function with the lamp body unit 10. The structures and functions of the first pivoting device 20a and the second pivoting device 20b of the pivoting device 20 are the same. The following further describes the structure and function of the pivoting device 20.

[0097] More preferably, in this preferred embodiment of the present invention, the first pivot device 20a and the second pivot device 20b of the pivot device 20 are arranged at two ends of the second lamp body unit 10b in a mutually reverse flipping manner. Let the flipping direction of the first pivot device 20a be the forward direction, and the flipping direction of the second pivot device 20b be the reverse direction. That is, when the folding work lamp rotates, the first lamp body unit 10a and the second lamp body unit 10b flip towards the illumination direction (the X-axis direction in the figure), so that when the folding work lamp is in the folded state, the light-emitting surface 101a of the first lamp body unit 10a faces the light-emitting surface 101b of the second lamp body unit 10b; the second lamp body unit 10b and the third lamp body unit 10c flip towards the reverse direction of the illumination direction (the reverse X-axis direction in the figure), so that when the folding work lamp is in the folded state, the backlight surface 102b of the second lamp body unit 10b faces the backlight surface 102c of the third lamp body unit 10c. In short, when the folding work lamp switches from the unfolded state to the folded state, the lamp body units 10 of the folding work lamp are folded into a three-fold structure. The first lamp body unit 10b is flipped by the first pivot device 20a and folded above the second lamp body unit 10b (along the X-axis direction in the figure), and the third lamp body unit 10c is flipped by the second pivot device 20b and folded below the second lamp body unit 10b (along the reverse direction of the X-axis in the figure).

[0098] As Figure 3 and Figure 4 shown, the locking device is arranged at one end of the first lamp body unit 10a and one end of the third lamp body unit 10c. When the folding work lamp is in the folded state, the two locking devices 30 can be pivoted to the locking position 301. The first pivot device 20a and the second pivot device 20b are in the hanging space 300 of the locking device 30 to limit the rotation of the first lamp body unit 10a and the third lamp body unit 10c. When the folding work lamp is in the folded state, when the locking device 30 pivots from the locking position 301 to the unlocking position 302, the locking space 300 of the locking device 30 is outside the first pivot device 20a and the second pivot device 20b, allowing the folding work lamp to rotate and unfold from the folded state to the unfolded state.

[0099] As Figure 8 and Figure 9As shown, the lamp body unit 10 includes a lamp body main body 11 and at least one light source 12 disposed on the lamp body main body 11. The light emitting surface 101 of the lamp body unit 10 is formed on the surface of the light source 12, and the light source 12 projects and irradiates light outward from the light emitting surface 101. The backlight surface 102 of the lamp body unit 10 is formed on the lamp body main body 11 and is disposed back-to-back with the light emitting surface 101. Preferably, in this preferred embodiment of the present invention, the light source 11 of the lamp body unit 10 is an LED light source, and the light source 11 is a light source in a long strip or plate shape structure. Those skilled in the art can understand that the shape of the lamp body unit 10 and the type of the light source 11 are only examples here, rather than limitations. In other alternative embodiments of the present invention, the lamp body unit 10 can also be implemented as a cylindrical structure, and the light source 11 can also be implemented as an OLED light source.

[0100] The lamp body unit 10 further includes a lamp body front end 13 and a lamp body rear end 14 extending from the lamp body front end 13. The first pivoting device 20a is pivotally disposed on the lamp body rear end 14 of the first lamp body unit 10a and the lamp body front end 13 of the second lamp body unit 10b. The second pivoting device 20b is pivotally disposed on the lamp body rear end 14 of the second lamp body unit 10b and the lamp body front end 13 of the third lamp body unit 10c. One of the locking devices 30 is disposed on the lamp body front end 13 of the first lamp body unit 10a, and the other locking device 30 is disposed on the lamp body rear end 14 of the third lamp body unit 10c.

[0101] Preferably, the light source 12 of the lamp body unit 10 is detachably disposed on the lamp body main body 11. More preferably, the light source 12 is snapped onto the upper end of the lamp body main body 11.

[0102] The lamp body unit 10 is further provided with at least one lamp body cavity 103. The light source 12 and the lamp body main body 11 together form the lamp body cavity 103, and the light source 12 is disposed above the lamp body cavity 103. It is worth mentioning that electronic components such as wires or conductors electrically connecting the lamp body unit 10 are arranged in the lamp body cavity 103 of the lamp body unit 10. The lamp body unit 10 further includes a partition 15. The partition 15 is disposed on the lamp body main body 11, and a telescopic space 104 is formed between the partition 15 and the lamp body main body 11. The partition 15 is spaced between the lamp body cavity 103 and the telescopic space 104. The locking device 30 is telescopically disposed in the telescopic space 104 of the lamp body unit 10.

[0103] Accordingly, the lamp body main body 11 is further provided with two symmetrical partition mounting grooves 110, the partition 15 is disposed in the partition mounting grooves 110, and the partition 15 is used to limit the locking device 30 to move in parallel and telescopically within the telescopic space 104.

[0104] As Figures 10 to 12 shown, the pivoting device 20 includes a first pivoting unit 21, a second pivoting unit 22 and a stopping unit 23. The first pivoting unit 21 is coupled to the second pivoting unit 22, and a stopping groove 201 is formed by the first pivoting unit 21 and the second pivoting unit 22. The stopping unit 23 is movably disposed in the stopping groove 201 of the pivoting device 20. The two lamp body units 10 are respectively disposed on the first pivoting unit 21 and the second pivoting unit 22 of the pivoting device 20. The first pivoting unit 21 and the second pivoting unit 22 are relatively rotatably disposed to facilitate the unfolding and folding of the two lamp body units 10 disposed on the pivoting device 20.

[0105] The first pivoting unit 21 is further provided with a first stopping unit 210, and the second pivoting unit 22 is further provided with a second stopping unit 220. The first stopping unit 210 of the first pivoting unit 21 corresponds to the second stopping unit 220 of the second pivoting unit 22, and the first stopping unit 210 of the first pivoting unit 21 and the second stopping unit 220 of the second pivoting unit 22 together form the stopping groove 201. The stopping unit 23 of the pivoting device 20 is movably disposed in the stopping groove 201 of the pivoting device 20. When the stopping unit 23 is located between the first stopping unit 210 of the first pivoting unit 21 and the second stopping unit 220 of the second pivoting unit 22, that is, when the stopping unit 23 is located between the first pivoting unit 21 and the second pivoting unit 22, the stopping unit 23 prevents the first pivoting unit 21 and the second pivoting unit 22 from rotating relative to each other, that is, the pivoting device 20 is in a stopping state. When the stopping unit 23 is pushed to the first stopping unit 210 of the first pivoting unit 21 or the second stopping unit 220 of the second pivoting unit 22, the stopping unit 23 can rotate relative to the first pivoting unit 21 with the second pivoting unit 22, or the stopping unit 23 can rotate relative to the second pivoting unit 22 with the first pivoting unit 21, that is, the pivoting unit is in a pivotable state.

[0106] Preferably, in this preferred embodiment of the present invention, the stopping unit 23 is pushed to the second stopping unit 220 of the second pivoting unit 22, where the stopping unit 23 is disengaged from the first pivoting unit 21 to allow the stopping unit 23 to rotate synchronously with the second pivoting unit 22.

[0107] Preferably, the stopping unit 23 includes a stopping body 231 and at least one tooth groove 232 formed on the stopping body 231, where the tooth groove 232 is disposed on the outer periphery of the stopping body 231. The first stopping unit 210 of the first pivoting unit 21 and the second stopping unit 220 of the second pivoting unit 22 are gear-shaped grooves adapted to the stopping unit 23. Accordingly, the first stopping unit 210 of the first pivoting unit 21 has a plurality of fixed positions. When the stopping unit 23 enters the first stopping unit 210 of the first pivoting unit 21, the tooth groove 232 of the braking unit 23 is fixed to a fixed position of the first pivoting unit 21, so that the pivoting device 20 is in the stopping state, preventing the two lamp body units 10 connected to the pivoting device 20 from rotating to maintain the position of the lamp body unit 10. Those skilled in the art can understand that the folding work lamp can be switched between a plurality of working positions between the folded state and the unfolded state, that is, the folding work lamp can be unfolded (or folded) to a plurality of working positions, and the pivoting device 20 can be locked at any working position to maintain the stability of the pose of the folding work lamp and prevent it from being unfolded or folded randomly.

[0108] As an example, in this preferred embodiment of the present invention, the pivoting device 20 is provided with a working position every 10° from the folded state to the unfolded state, that is, the first pivoting unit 21 and the second pivoting unit 22 of the pivoting device 20 can be fixed when they rotate relative to each other by 10° from the folded state to the unfolded state, and the relative positions and angles of the two lamp body units 10 connected to the pivoting device 20 are kept fixed, so that the folding work lamp has a variety of lighting postures to adapt to different lighting environments and maintain the pose stability of the folding work lamp in different lighting environments. Those skilled in the art can understand that the fixed working positions of the pivoting device 20 are only examples here and are not restrictive. Therefore, in other alternative embodiments of the present invention, the pivoting device 20 can also be implemented in a stepless adjustment manner to fix the working positions of the lamp body units 10.

[0109] The pivot device further includes at least one reset device 24 and a push button 25. The reset device 24 is disposed on the second stop unit 220 of the second pivot unit 22, and the push button 25 is disposed on the first pivot unit 21. The stop unit 23 has a stop position and a pivotable position. When the stop unit 23 is in the stop position, that is, when the stop unit 23 is located between the first stop unit 210 of the first pivot unit 21 and the second stop unit 220 of the second pivot unit 22, the stop unit 23 prevents the relative rotation of the first pivot unit 21 and the second pivot unit 22. It is worth mentioning that the reset device 24 pushes the stop unit 23 to the stop position under the elastic action. The push button 25 is movably disposed on the first pivot unit 21, and the stop unit 23 is drivingly connected to the push button 25, wherein the push button 25 can push the stop unit 23 from the stop position to the pivotable position, so that the pivot device 20 is in the pivotable state.

[0110] The first pivot unit 21 includes a first receiving portion 211, a first rotating body 212, and a first rotating shaft 213. The first rotating shaft 213 and the first receiving portion 211 are disposed on the first rotating body 212, and the lamp unit 10 is disposed on the first receiving portion 211 of the first pivot unit 21.

The receiving portion 221 and the third rotating shaft 223 of the second pivot unit 22 are disposed on the second rotating body 222, and the lamp unit 10 is disposed on the second receiving portion 221 of the second pivot unit 22. The first stop unit 210 is formed on the first rotating body 212 of the first pivot unit 21, and the second stop unit 220 is formed on the second rotating body 222 of the second pivot unit 22. The first rotating shaft 213 of the first pivot unit 21 and the second rotating shaft 223 of the second pivot unit 22 are coaxially disposed, allowing the first rotating shaft 213 of the first pivot unit 21 to rotate relative to the second rotating shaft 223 of the second pivot unit 22.

[0111] Preferably, the first receiving portion 211 of the first pivoting unit 21 faces the second receiving portion 221 of the second pivoting unit 22. When the folding work lamp is in the folded state, the lamp body unit 10 connected to the first receiving portion 211 of the first pivoting unit 21 and the lamp body unit 10 connected to the second receiving portion 221 of the second pivoting unit 22 can be positively corresponding to avoid the lamp body units 10 from being interlaced with each other. It can be understood that when the folding work lamp is in the folded state, the two lamp body units 10 connected by the pivoting device 20 are stacked one above the other, further reducing the space required for storing the folding work lamp.

[0112] Preferably, in this preferred embodiment of the present invention, the first rotating shaft 213 of the first pivoting unit 21 is sleeved outside the second rotating shaft 223 of the second pivoting unit 22, and the first pivoting unit 21 and the second pivoting unit 22 are pivotally fixed by the first rotating shaft 213 and the second rotating shaft 223. Those skilled in the art can understand that the first rotating shaft 213 and the second rotating shaft 223 can be pivotally fixed by means of screw fixation. The stopping unit 23 is movably disposed on the first rotating shaft 213 of the first pivoting unit 21 and is held in the stopping position under the thrust of the reset device 24. When the stopping unit 23 is in the stopping position and is acted upon by the pushing button 25, it is pushed along the first rotating shaft 213 to the pivotable position.

[0113] The first receiving portion 211 has a first receiving space 2110, and the second receiving portion 221 has a second receiving space 2210. The front end 13 or the rear end 14 of the lamp body of the lamp body unit 10 is fixedly disposed in the first receiving space 2110 of the first receiving portion 211 or the second receiving space 2210 of the second receiving portion 221. The first pivoting unit 21 further has a first convex arc surface 214 and a first concave arc surface 215, wherein the first convex arc surface 214 is formed on the first rotating body 212, and the first concave arc surface 215 is formed on the first receiving portion 211. The second pivoting unit 22 further has a second convex arc surface 224 and a second concave arc surface 225, wherein the second convex arc surface 224 is formed on the second rotating body 222, and the second concave arc surface 225 is formed on the second receiving portion 221. The first convex arc surface 214 of the first pivoting unit 21 faces the second concave arc surface 225 of the second pivoting unit 22, and the second convex arc surface 224 of the second pivoting unit 22 faces the first concave arc surface 225 of the first pivoting unit 21, so as to allow the first pivoting unit 21 and the second pivoting unit 22 to rotate coaxially. Preferably, in this preferred embodiment of the present invention, the first rotating body 212 of the first pivoting unit 21 and the second rotating body 222 of the second pivoting unit 22 are implemented as cylindrical structures, that is, the first convex arc surface 214 of the first pivoting unit 21 and the second convex arc surface 224 of the second pivoting unit 22 are arc surfaces. More preferably, the first rotating body 212 and the first receiving portion 211 are of an integral structure, and the second rotating body 222 and the second receiving portion 221 are of an integral structure.

[0114] The first receiving portion 211 has an upper surface 2111 of the first receiving portion and a lower surface 2112 of the first receiving portion. The upper surface 2111 of the first receiving portion and the lower surface 2112 of the second receiving portion are arranged back to back. The second receiving portion 221 has an upper surface 2211 of the second receiving portion and a lower surface 2212 of the second receiving portion. The upper surface 2211 of the second receiving portion and the lower surface 2212 of the second receiving portion of the second receiving portion 221 are arranged back to back. Preferably, the plane where the upper surface 2111 of the first receiving portion 211 is located is parallel to the tangent plane at the connection of the first convex arc surface 214 of the first pivoting unit 21 and the first receiving portion 211. The plane where the upper surface 2211 of the second receiving portion 212 is located is parallel to the tangent plane at the connection of the second convex arc surface 224 of the second pivoting unit 22 and the second receiving portion 221. When the first pivoting unit 21 and the second pivoting unit 22 of the pivoting device 20 are rotated to the unfolded state, the first receiving portion 211 of the first pivoting unit 21 abuts against the second receiving portion 221 of the second pivoting unit 22 to prevent the pivoting device 20 from continuing to rotate. It can be understood that when the first receiving portion 211 of the first pivoting unit 21 abuts against the second receiving portion 221 of the second pivoting unit 22, that is, when the lamp body unit 10 is fully unfolded, the first receiving portion 211 of the pivoting device 20 and the second receiving portion 221 of the second pivoting unit 22 are rotated to a flat angle state, that is, the two lamp body units 10 connected to the pivoting device 20 extend in the same length direction, thereby maximizing the illumination length of the folding work lamp in the unfolded state. In other words, when the folding work lamp is in the unfolded state, the first receiving portion 211 of the pivoting device 20 and the second receiving portion 221 are facing each other in the positive direction, and the upper surface 2111 of the first receiving portion 211 extends reversely in parallel with the upper surface 2121 of the second receiving portion 212 of the second receiving portion. When the folding work lamp is in the folded state, the first receiving portion 211 of the pivoting device 20 and the second receiving portion 221 are facing each other in the reverse direction, and the lower surface 2112 of the first receiving portion 211 and the lower surface 2122 of the second receiving portion 212 of the second receiving portion are arranged face to face.

[0115] Preferably, in this preferred embodiment of the present invention, the radian angles corresponding to the first concave arc surface 215 of the first pivoting unit 21 and the second concave arc surface 225 of the second pivoting unit 22 are approximately 90° or slightly less than 90°, that is, the diameter of the first rotating body 212 of the first pivoting unit 21 is twice the thickness of the first receiving portion 211, so that when the folding work lamp is in the folded state, the backlight surfaces 102 (or light emitting surfaces 101) of the two lamp body units 10 connected by the pivoting device 20 can face each other directly.

[0116] As Figure 12 shown, the first pivoting unit 21 of the pivoting device 20 is further provided with a first wire groove 216, wherein the first wire groove 216 communicates with the first receiving space 2110 of the first receiving portion 211 and the first stopping unit 210. The second pivoting unit 22 of the pivoting device 20 is further provided with a second wire groove 226, wherein the second wire groove 226 communicates with the second receiving space 2210 of the second receiving portion 221 and the second stopping unit 220. It can be understood that the wires of the two lamp body units 10 disposed on the pivoting device 20 reach the first stopping unit 210 from the first receiving space 2110 of the first receiving portion 211 through the first wire groove 216, and then reach the second receiving space 2210 of the second receiving portion 221 through the second stopping unit 220 through the second wire groove 226, so as to realize the electrical connection of the two lamp body units 10.

[0117] As Figures 13 to 16 shown, the locking device 30 includes a locking body 31 and a telescopic device 32, wherein the telescopic device 32 is disposed on the locking body 31 and extends from the locking body 31. The telescopic device 32 of the locking device 30 is telescopically disposed on the lamp body 11 of the lamp body unit 10. By pulling the telescopic device 32 of the locking device 30 from the telescopic space 104 of the lamp body unit 10 to the outside of the lamp body unit 10 by the locking body 31 of the locking device 30, the length of the folding work lamp is extended or the hooking range of the locking body 31 is expanded to adapt to the working scenario of the folding work lamp. As Figure 5 shown, when performing engine maintenance on a vehicle, the locking body 31 of the locking device 30 at both ends of the folding work lamp is pulled, so that the telescopic device 32 of the locking device 30 is pulled out from the telescopic space 104 of the lamp body unit 10, so that the folding work lamp can be hooked on both sides of the vehicle engine hood.

[0118] The locking body 31 is pivotally arranged on the telescopic device 32. The locking body 31 has a rotating shaft, and the locking body 31 can rotate based on the rotating shaft. Preferably, the locking body 31 can rotate freely based on the rotating shaft, that is, the locking body 31 can rotate 360° at the end of the telescopic device 32 to adjust the position and angle of the locking space 300.

[0119] The telescopic device 32 is telescopically arranged in the telescopic space 104 of the lamp body unit 10, and the telescopic device 32 can reciprocally move in the telescopic space 104 of the lamp body unit 10. Specifically, the telescopic device 32 includes a telescopic rod 321 and a slider 322. The slider 322 is arranged at one end of the telescopic rod 321 and is used to limit the movement of the telescopic rod 321. The telescopic rod 321 further includes a traction end 3211 and a sliding end 3212 extending from the traction end 3211. The slider 322 is fixedly arranged at the sliding end 3212 of the telescopic rod 321, and the traction end 3211 of the telescopic rod 321 is fixed to the locking body 31 of the locking device 30.

[0120] The locking body 31 drives the slider 322 to move synchronously with the telescopic rod 321 through the traction end 3211 of the telescopic rod 321. The lamp body 11 further includes a slide rail 111, and the slide rail 111 protrudes inwards from the telescopic space 104 of the lamp body unit 10.

[0121] The locking device 30 further includes at least one traction unit 33. The traction unit 33 is telescopically arranged between the telescopic rod 321 of the locking device 30 and the lamp body 11 of the lamp body unit 10. The traction unit 33 is in a stretched traction state, and the telescopic rod 321 of the locking device 30 is tractioned by the traction unit 33 so that the locking body 31 of the locking device 30 is in a tightened state, which is convenient for hooking on the object to be hooked.

[0122] Preferably, one end of the traction unit 33 is arranged at the sliding end 3212 of the telescopic rod 321, and the other end of the traction unit 33 is arranged at the front end 13 or the rear end 14 of the lamp body of the lamp body unit 10. Preferably, in this preferred embodiment of the present invention, the traction unit 33 of the locking device 30 can be but not limited to elastic devices such as elastic rubber bands, springs, and tension belts.

[0123] As Figure 14As shown, the locking body 31 of the locking device 30 is pivotally arranged on the telescopic device 32. The locking body 31 includes a holder 311, a rotating unit 312, and a hooking unit 313 arranged on the rotating unit 312.
