Abstract

The invention relates to a lighting device convenient to store, which comprises a support rod, a movable rod and a lamp holder which are connected in sequence, and the lamp holder moves or swings relative to the support rod along with the movable rod, so that the lighting direction of the lamp holder can be changed, and the whole lighting device can be folded and stored. The lamp holder is electrically connected to the main board in the supporting rod through the electric lead so as to achieve power supply, the electric lead sequentially passes through the movable rod and the supporting rod, and the elastic piece is fixed between the supporting rod and the movable rod and arranged on the electric lead in a sleeving mode. In the process that the movable rod moves or swings relative to the supporting rod, the electric lead is pulled out by the redundant length at the connecting position of the movable rod and the supporting rod, and the elastic piece is also stretched to accumulate elastic force. And in the resetting process of the movable rod, the elastic piece shrinks, and meanwhile, the conductive wire is guided to retract into the movable rod or the supporting rod. Meanwhile, when the elastic piece is arranged outside the conductor wire in a sleeving mode, the effect of preventing other parts of the conductor wire from being scratched and damaged is achieved.

In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0034] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements.

[0035] Reference Figure 1 and Figure 2 This application provides a lighting device 10, which can switch between an unfolded state and a retracted state. In this embodiment, Figure 1 This illustration shows the lighting device 10 in its retracted state. In this state, the lighting device 10 can be held and carried by the user to provide illumination. For example, the user can obtain light by holding the lighting device 10, making it convenient for the user to move around at night. At the same time, when the lighting device 10 is in its retracted state, its size and space occupation are small, making it convenient to store and carry. Figure 2 This indicates that the lighting device 10 is in the deployed state. In this deployed state, the lighting device 10 has a higher illumination height and a wider illumination range. In this position, the user can hold it by hand, providing illumination over a large area while camping outdoors. It can also be used as a mobile streetlight or detector when traveling at night, facilitating both navigation and observation of the surrounding environment. Alternatively, refer to... Figure 3 In other usage scenarios, the lighting device 10 can be further unfolded into a support configuration, allowing it to be placed on a flat or uneven surface to provide illumination. For example, when reading or using a computer at home at night, appropriate lighting is needed to protect the eyes from strong light; in this case, the lighting device 10 can be supported on a table and used as a desk lamp. It should be understood that the lighting device 10 may not necessarily be able to unfold into a full-length support configuration. Figure 3 The bracket configuration shown only requires that the lighting device 10 is able to... Figure 1 The folded storage state shown is as follows: Figure 2 Simply switch between the shown unfolded states. Alternatively, provided the supporting structure of the lighting device 10 is sufficiently robust, the user can also directly... Figure 2 The lighting device 10, in its unfolded state, is supported on a support surface.

[0036] Reference Figure 1 and Figure 2The lighting device 10 of this application includes a support rod 100, a movable rod 200, and a lamp head 300 connected in sequence. The movable rod 200 is movably connected to the support rod 100. The lamp head 300 serves as the lighting element of the lighting device 10, emitting light to provide a light source for the user. The lamp head 300 is connected to the free end of the movable rod 200 (the other end of the movable rod 200 relative to the support rod 100). The movable rod 200 moves relative to the support rod 100, allowing the entire lighting device 10 to switch freely between an unfolded state and a folded state. Preferably, in this embodiment, the movable rod 200 is rotatably connected to the outside of the support rod 100. The movable rod 200 tilts relative to the support rod 100 along the axial direction of the support rod 100 until the movable rod 200 and the support rod 100 are side by side, achieving the folding and storage of the entire lighting device 10. It should be understood that, in other embodiments, firstly, the lamp head 300 can be directly connected to the support rod 100 to form the lighting device 10; in this application, the presence or absence of the movable rod 200 is not limited. Secondly, in other embodiments, the pitch angle of the movable rod 200 relative to the support rod 100 is not limited; that is, the movable rod 200 may not necessarily swing to be parallel to the support rod 100 to achieve the folded state of the lighting device 10. In other words, in this application, whether the lighting device 10 is folded and stored is not limited.

[0037] Specifically, in this embodiment, the support rod 100, as a supporting body, has a support end 101 and a mounting end 102 that are opposite each other along its axial direction. When the lighting device 10 is in the unfolded state, the support rod 100 can support the lighting device 10 on the support surface. The movable rod 200 has a first connecting end 201 and a second connecting end 202 that are opposite each other along its axial direction. The first connecting end 201 is connected to the mounting end 102; the second connecting end 202 is connected to the lamp holder 300. Preferably, in this embodiment, the first connecting end 201 is rotatably connected to the mounting end 102. When the first connecting end 201 rotates relative to the mounting end 102, the angle between the movable rod 200 and the support rod 100 changes, and the movable rod 200 can be flipped to be parallel to the support rod 100. At this time, the movable rod 200 is folded and stored on the side of the support rod 100, so that the lighting device 10 switches from the unfolded state to the stored state. Figure 1 As shown, when the lighting device 10 is in the retracted state, that is, when the movable rod 200 and the support rod 100 are in a side-by-side and close-to-each side posture, the lamp head 300 is fastened to the support end 101. Here, fastening means that the two are tightly joined together, which can be achieved by means of snaps, hooks, adhesives, magnets, etc.; the lamp head is fastened to the support end 101, including but not limited to the lamp head 300 being able to fasten to the side, edge, or bottom of the support end 101.

[0038] Preferably, in this embodiment, in conjunction with reference to... Figure 3 and Figure 4The support rod 100 includes a central shaft 110, a support plate 120, a reset member 130, and a bracket 140. The two opposite ends of the central shaft 110 along its axial direction correspond to the previously mentioned support end 101 and mounting end 102, respectively. The lamp head 300 is connected to the mounting end 102 via a movable rod 200. The lamp head 300 is mounted and connected to the central shaft 110 and is circumferentially limited (the circumferential limitation here means that the lamp head 300 cannot rotate relative to the central shaft 110 around its circumference). The support plate 120 is rotatably connected to the support end 101 along the circumference of the central shaft 110. The reset member 130 is located between the support end 101 (central shaft 110) and the support plate 120 and accumulates a reset force along the axial direction of the central shaft 110. This reset force continuously acts on the support plate 120 and abuts the support plate 120 against the support end 101 of the central shaft 110. The tripod 140 is connected to the side of the support plate 120 and is circumferentially limited (the circumferential limitation here means that the tripod 140 cannot rotate relative to the support plate 120 around the central axis 110). The tripod 140 can be in an unfolded support state to support the lighting device 10 on the support surface.

[0039] Specifically, in conjunction with reference Figures 5-7 The supporting end 101 of the central shaft 110 is provided with a first baffle 111 and a second baffle 112. The first baffle 111 and the second baffle 112 are opposite to each other and spaced apart along the axial direction of the central shaft 110. The support plate 120 is clamped and installed between the first baffle 111 and the second baffle 112. The reset member 130 is provided between the first baffle 111 and the support plate 120. Along the axial direction of the central shaft 110, the reset force released by the reset member 130 continuously acts on the support plate 120 and abuts the support plate 120 against the second baffle 112. The reset force is converted into the extrusion force between the surfaces of the support plate 120 and the second baffle 112, increasing the extrusion force between the support plate 120 and the second baffle 112 to increase the rotational damping between the support plate 120 and the central shaft 110.

[0040] In this application, the lamp head 300 is connected to the mounting end 102 of the central shaft 110 and is circumferentially limited, and the stand 140 is connected to the support plate 120 and is circumferentially limited. Therefore, when the central shaft 110 and the support plate 120 rotate relative to each other circumferentially along the central shaft 110, the lamp head 300 rotates circumferentially relative to the stand 140. When the central shaft 110 and the support plate 120 are stationary relative to each other circumferentially, the lamp head 300 is stationary relative to the stand 140 circumferentially, and the circumferential lighting orientation of the lamp head 300 is fixed. A reset member 130 is provided between the central shaft 110 and the support plate 120. The reset force released by the reset member 130 along the central shaft 110 is converted into a resisting force between the central shaft 110 and the support plate 120, increasing the rotational damping between them. On the one hand, this limits the circumferential misalignment of the lamp head 300 in a certain stationary state, and on the other hand, it increases the stability of the lighting device 10 in the relatively stationary state between the lamp head 300 and the stand 140. The support stability of the bracket 140 in the lighting device 10 is enhanced, allowing users to obtain a stable light source.

[0041] It should be understood that in other embodiments, the lamp head 300 and the mounting end 102 can also rotate circumferentially relative to each other, as long as the lamp head 300 and the mounting end 102 can stop at a certain fixed rotation angle during rotation, so that the lamp head 300 and the central shaft 100 can rotate synchronously together, and both rotate synchronously relative to the support plate 120 and the support frame 140. That is, this application does not limit whether the lamp head 300 and the mounting end 102 are circumferentially limited.

[0042] Preferably, in this embodiment, reference Figures 5-7 The bottom of the support end 101 is provided with a bottom end face 113 and a limiting shaft 103. The limiting shaft 103 includes a shaft body 114 and a boss 115 connected to the end of the shaft body 114. The other end of the shaft body 114 away from the boss 115 is connected to the bottom end face 113. The boss 115 extends radially along the shaft body 114 and forms a stepped surface 116 on the side of the boss 115 facing the bottom end face 113. The reset member 130 surrounds the shaft body 114, and the support plate 120 is passed through the shaft body 114. The support plate 120 rotates around the shaft body 114 relative to the central shaft 110. Figure 5 As shown, in this embodiment, the support plate 120 abuts against the stepped surface 116, the stepped surface 116 of the boss 115 is the second baffle 112, and the bottom surface 113 is the first baffle 111. The first baffle 111 is closer to the mounting end 102 along the axial direction of the central axis 110 than the second baffle 112. Figure 4(As shown). It should be understood that in other embodiments, the support plate 120 may also abut against the bottom surface 113. In this case, the bottom surface 113 is the second baffle 112, and the stepped surface 116 is the first baffle 111. The first baffle 111 is further away from the mounting end 102 along the axial direction of the central axis 110 than the second baffle 112. It should be noted that in this application, the distance between the first baffle 111 and the second baffle 112 and the mounting end 102 is not limited. The first baffle 111 and the second baffle 112 have relative meanings. In this application, for ease of description and understanding, the surface against which the support plate 120 abuts is defined as the second baffle 112, and the other is defined as the first baffle 111.

[0043] It should also be understood that the limiting shaft 103 is only one specific way to achieve the circumferential rotation of the support plate 120. In other embodiments, an annular groove circumferentially around the central axis 110 is formed on the side circumference of the bottom end surface 113, and the support plate 120 is provided with an aligning annular protrusion. The annular protrusion engaging with the annular groove can also achieve the circumferential rotation of the support plate 120. That is, the structural method for achieving the circumferential rotation of the support plate 120 in this application is not limited.

[0044] Preferably, in conjunction with reference Figure 5 and Figure 6 The support plate 120 has a receiving groove 121 on its end face facing the bottom end face 113 (facing the mounting end 102). The opening of the receiving groove 121 faces the bottom end face 113. A first baffle wall 111 covers the opening of the receiving groove 121. The reset member 130 is received and housed in the receiving groove 121, and is located between the bottom wall of the receiving groove 121 and the first baffle wall 111. This design isolates the reset member 130 from the outside world and protects it from damage such as impacts and corrosion from the external environment. Furthermore, referring to the reference... Figure 5 and Figure 7 A mounting groove 122 is provided on the end face of the support plate 120 opposite to the storage groove 121 (opposite to the mounting end 102). The mounting groove 122 accommodates the boss 115, so that the boss 115 does not protrude from the end face of the support plate 120 opposite to the mounting end 102. The mounting groove 122 makes the structure of the support plate 120 more compact, and the boss 115 is protected by the mounting groove 122 from contacting other components, thus reducing wear.

[0045] It should be understood that, firstly, without considering the housing and accommodating features of the reset member 130 and the boss 115, the presence or absence of the housing groove 121 and the mounting groove 122 is not limited in this application. Secondly, in other embodiments, when the second baffle 112 is closer to the mounting end 102 than the first baffle 111, and the support plate 120 abuts against the bottom end face 113 of the support end 101, the housing groove 121 is formed on the end face of the support plate 120 facing away from the bottom end face 113 (facing away from the mounting end 102), and the opening of the housing groove 121 faces away from the bottom end face 113. In this case, the mounting groove 122 is not required, and if the housing groove 121 is sufficiently deep, the boss 115 is directly accommodated within the housing groove 121. Therefore, in this application, the location of the housing groove 121 is not limited, and the housing groove 121 can be provided on any end face of the support plate 120 opposite to each other along the central axis 110.

[0046] Preferably, in conjunction with reference Figure 5 and Figure 6 The bottom wall of the receiving groove 121 protrudes axially along the central axis 110 with a hollow column 123. The hollow column 123 is sleeved on the outer wall of the shaft 114, and the reset member 130 surrounds the outer wall of the hollow column 123. This design increases the connection stability between the support plate 120 and the support end 101. Of course, in other embodiments, without considering connection stability, it is not limited whether the support plate 120 is provided with a hollow column 123.

[0047] Finally, preferably, refer to Figure 4In this embodiment, the reset member 130 includes a plurality of wave-shaped washers 131 stacked sequentially along the central axis 110. The user can change the magnitude of the reset force by increasing or decreasing the number of wave-shaped washers 131 as needed. It should be noted that the wave-shaped washers 131 are also called corrugated washers, which are regular, wavy circular thin sheets generally used to prevent loosening and mitigate impacts, requiring good elasticity and impact resistance. It is important to understand that stacking multiple wave-shaped washers 131 to form the reset member 130 is merely a specific way to accumulate reset force. For example, in one embodiment, the reset member 130 includes a telescopic spring, which is sleeved on the outer wall of the shaft 114. The telescopic spring is compressed along the central axis 110 to accumulate elastic force, which continuously acts on the support plate 120 and abuts the support plate 120 against the second baffle 112. In another embodiment, the reset member 130 includes a first magnet and a second magnet. The first magnet is disposed on the support plate 120, and the second magnet is disposed on the first baffle 111. In this case, the first magnet and the second magnet repel each other, causing the support plate 120 to abut against the second baffle 112. That is, in this application, the implementation of the reset member 130 is not limited. The reset member 130 includes, but is not limited to, multiple wave-shaped pads 131, a telescopic spring, and two magnets. When the reset member 130 is multiple wave-shaped pads 131 or a spring, the user can apply force along the axial direction of the central axis 110 to squeeze the wave-shaped pads 131 or the spring until they deform and accumulate elastic force to install it between the first baffle 111 and the second baffle 112.

[0048] Preferably, in conjunction with reference Figure 3 and Figure 4 In this embodiment, the stand 140 includes a sleeve 141, multiple tube feet 142, and multiple legs 143. The number of tube feet 142 and legs 143 are the same and correspond one-to-one. The sleeve 141 is sleeved on the outside of the central shaft 110 and can rotate circumferentially. The sleeve 141 is slidably connected to the central shaft 110 along the axial direction. The tube feet 142 have a rotating end 1421 and a fixed end 1422 that are opposite to each other along their axial direction. The rotating end 1421 is rotatably connected to the side of the sleeve 141, and the fixed end 1422 is supported on the support surface away from each other. The legs 143 are connected between the support plate 120 and the tube feet 142. The legs 143 have a movable end 1431 and a free end 1432 that are opposite to each other along their axial direction. The movable end 1431 is rotatably connected to the side of the support plate 120, and the free end 1432 is rotatably connected to the inside of the tube feet 142. The above describes how multiple pins 142 can be in the closed state. Figure 2 ) and unfolded state ( Figure 3 Switching between ) and correspondingly, the outrigger 143 is synchronously driven to rotate by the pin 142 and is in the closed state ( Figure 2 ) and unfolded state ( Figure 3 Switch between ) . For details, refer to Figures 2-3When the rotating end 1421 flips outward toward the sleeve 141, it simultaneously drives multiple fixed ends 1422 to switch from a state of being close together to a support state of being far apart. Simultaneously, the tube pins 142 drive the corresponding connected free ends 1432 to switch from a state of being close together to a support state of being far apart, and the movable end 1431 flips outward relative to the support plate 120. Thus, multiple tube pins 142 and multiple legs 143 all change from a closed state (…). Figure 2 Switch to support mode. Figure 3 This allows the tripod 140 to switch from the retracted state to the extended state. At this time, the outrigger 143 acts as an intermediate support frame, making the extended state of the entire tripod 140 more stable. The sleeve 141 and the support plate 120 rotate synchronously in the circumferential direction, thereby driving the tube leg 142 and the outrigger 143 to rotate synchronously.

[0049] It should be understood that, firstly, in other embodiments, the stand 140 may not include the sleeve 141 and the tube feet 142. In this case, the stand 140 is directly supported on the support surface by multiple legs 143 that are extended at an angle. The movable end 1431 of the legs 143 is rotatably connected to the side periphery of the support plate 120. The movable end 1431 rotates relative to the support plate 120 toward the central axis 110, simultaneously causing the free ends 1432 to switch from a supporting state where they are far apart to a retracted state where they are close together, so that the multiple legs 143 switch from an angled extended state to a side-by-side closed posture. In this embodiment, when the multiple legs 143 are in the side-by-side closed state, the free ends 1432 are close to each other and surround and abut against the outer wall of the central axis 110, and the multiple legs 143 surround the outer wall of the central axis 110. Secondly, in other embodiments, the movable end 1431 can also be fixedly connected to the side periphery of the support plate 120, with multiple legs 143 in an angled extended state, and the free end 1432 directly used to support the support surface, making it impossible to retract the tripod 140. Therefore, in this application, without considering a more stable and secure support state, the inclusion or exclusion of the sleeve 141 and multiple legs 142 is not limited. Without considering whether the tripod 140 can be retracted, the rotatable connection between the movable end 1431 of the legs 143 and the support plate 120 is not limited.

[0050] Preferably, refer to Figure 1 In this embodiment, when the entire lighting device 10 is in a fully retracted state, i.e., the stand 140 is closed and the movable rod 200 and support rod 100 are side by side, the lamp head 300 is fastened to the end face of the support end 101 and simultaneously to the bottom end of the stand 140. This further stabilizes the fully retracted posture of the entire lighting device 10 and the closed posture of the stand 140. It should be understood that in other embodiments, without considering the retracted stability of the lighting device 10, the position of the lamp head 300 fastening to the support end 101 is not limited, nor is it limited whether the lamp head 300 is fastened to the support end 101.

[0051] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
