[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The present invention relates to a self-parallel light pole, comprising an upper support 100, a lower support 110, a first connecting rod 200, a second connecting rod 300, a third connecting rod 400, and a fourth connecting rod 500.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, the upper support 100 and the lower support 110 are distributed vertically, respectively. The shapes of the upper support 100 and the lower support 110 are not limited, and both the upper support 100 and the lower support 110 can be strip-shaped frame structures. In this embodiment, both the upper support 100 and the lower support 110 are horizontally oriented front to back. The first connecting rod 200 is in the shape of a long support rod, and the upper end of the first connecting rod 200 can be hinged to the upper support 100 through components such as a pivot, rivet, or screw. The hinge point between the upper end of the first connecting rod 200 and the upper support 100 is defined as the first hinge point 210. The first hinge point 210 can be a single joint or two symmetrical joints, that is, the upper end of the first connecting rod 200 has two symmetrical joints, and these two joints are hinged to the upper support 100 through the same pivot. The second connecting rod 300 is a long rod structure, and the lower end of the second connecting rod 300 can be hinged to the lower support 110 through components such as a pivot, rivet, or screw. The hinge point between the second link 300 and the lower support 110 is defined as the second hinge point 310. The first link 200 and the second link 300 can be configured to be parallel to each other. When the first link 200 rotates around the first hinge point 210 and the second link 300 rotates around the second hinge point 310, the first link 200 and the second link 300 remain parallel to each other, that is, the first link 200 and the second link 300 always maintain the same swing angle, while relative movement occurs between the first link 200 and the second link 300, and both the first link 200 and the second link 300 undergo relative translation along their length. In this embodiment, a first guide structure is provided on the first link 200, and the first guide structure is arranged along the length direction of the first link 200. The second link 300 is slidably connected to the first link 200 through the first guide structure, which allows the first link 200 and the second link 300 to maintain relative sliding along their length direction during the swinging process. The first guide structure can be a guide component such as a slide rail. In this embodiment, a first guide groove 220 is provided inside the first connecting rod 200, and the first guide groove 220 is opened along the length direction of the first connecting rod 200. The second connecting rod 300 is inserted into the first guide groove 220 and slides relative to the first connecting rod 200 along the first guide groove 220. A third connecting rod 400 is connected between the upper bracket 100 and the second connecting rod 300. One end of the third connecting rod 400 is hinged to the upper bracket 100, and this hinge point is defined as the third hinge point 410. The other end of the third connecting rod 400 is hinged to the upper end of the second connecting rod 300, and this hinge point is defined as the fourth hinge point 420. The third hinge point 410 and the fourth hinge point 420 can be connected by components such as a rotating shaft, rivet, or screw. In the direction shown in Figure 3, the third hinge point 410 is located in front of the first hinge point 210. Preferably, the third hinge point 410 and the first hinge point 210 are at the same horizontal height, or the third hinge point 410 and the first hinge point 210 have a first height difference.The fourth hinge point 420 is located below the first hinge point 210, and these three points—the first hinge point 210, the third hinge point 410, and the fourth hinge point 420—form a triangular distribution in space. The lower end of the fourth link 500 is hinged to the lower support 110, and this hinge point is defined as the fifth hinge point 510; the upper end of the fourth link 500 is hinged to the lower end of the first link 200, and this hinge point is defined as the sixth hinge point 520. One or two fourth links 500 can be connected between the first link 200 and the lower support 110, and the two fourth links 500 are symmetrically installed. The fifth hinge point 510 and the sixth hinge point 520 can be connected by components such as a pivot, rivet, or screw. When the second link 300 and the fourth link 500 swing relative to the lower support 110, the sixth hinge point 520 can move linearly relative to the length of the second link 300. A second guide structure can be provided on the second connecting rod 300, extending along the length of the second connecting rod 300. The second guide structure can be a slide rail component, with the pivot at the sixth hinge point 520 sliding along the second guide structure. In this embodiment, a second guide groove 320 is formed at the lower part of the second connecting rod 300 along its length. The sixth hinge point 520 passes through the second guide groove 320 via a pivot, and slides along the second guide groove 320. The second guide groove 320 constitutes the second guide structure. Simultaneously, the length of the second guide groove 320 can be used to limit the displacement stroke of the sixth hinge point 520, thereby controlling the overall swing stroke of the parallel lamp post. In the illustrated direction, the second hinge point 310 is located in front of the fifth hinge point 510, and the sixth hinge point 520 is located above the second hinge point 310. The second hinge point 310, the fifth hinge point 510, and the sixth hinge point 520 form a triangular distribution in space.

[0043] During the linkage process of the parallel light pole, the lower bracket 110 remains fixed at a fixed point. Pushing the first connecting rod 200 forward causes the second connecting rod 300 to swing forward synchronously and at the same angle around the second hinge point 310. The sixth hinge point 520 moves forward with the second connecting rod 300, causing the fourth connecting rod 500 to swing forward around the fifth hinge point 510. At this time, the sixth hinge point 520 pulls the first connecting rod 200 downward relative to the second connecting rod 300 along the length of the second connecting rod 300. Under the supporting action of the third connecting rod 400 and the pulling action of the first connecting rod 200 on the upper bracket 100, the third hinge point 410 and the first hinge point always remain at the same horizontal height or maintain the same relative height difference, such as... Figure 3 and Figure 4 As shown, regardless of its height, the upper support 100 always maintains the same orientation. Specifically, as... Figure 5 and Figure 6As shown, the parallel lamp post is applied to a table lamp. The first connecting rod 200 serves as the lamp post, the lower bracket 110 is mounted on the lamp holder 700, and the upper bracket 100 mounts the lamp head 710. Taking the downward lighting direction of the lamp head 710 as an example, when the first connecting rod 200 is swung, the lamp head 710 swings with the upper bracket 100 under the linkage of the parallel lamp post. Since the orientation of the upper bracket 100 remains unchanged, the lamp head 710 can always maintain downward lighting regardless of the height it moves to, without adjusting the position of the lamp head 710 relative to the upper bracket 100.

[0044] To position the first link 200 at its current swing position, an external damping component can be used to increase friction at each hinge point, thus positioning the lamp at the current height for use. When the first link 200 swings forward and downward to a relatively low position, the upper bracket 100, connected to the lamp head 710 and other components, generates a large torque on the lower bracket 110. This requires greater damping to position it or a larger external force to swing it upward and reset it. Therefore, an elastic element 600 is installed at the second hinge point 310. The elastic element 600 elastically compresses the second link 300 during its downward swing, exerting an elastic force on it. This elastic force tends to cause the second link 300 to swing upward and tilt. The elastic element 600 provides support for the second link 300 when it swings to a relatively low position and also assists in resetting it during its upward swing, saving the required external force. Specifically, the elastic element 600 can be a torsion spring, which is sleeved on the pivot of the second hinge point 310. One end of the torsion spring extends to abut against the second connecting rod 200, and the other end abuts against the lower bracket 110.
