Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and in particular to a lamp. Background Technology

[0002] In related technologies, a lamp for the screen of electronic devices can provide both illumination and eye protection for the user. However, the common method of using a torsion spring to secure the lamp to the screen with a clip can easily damage the screen. Therefore, how to secure the lamp to the screen without causing damage is a problem that needs to be addressed. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a lamp that can clamp and fix to the screen of an electronic device, while reducing clamping damage to the screen.

[0004] The lamp according to an embodiment of the present invention includes: a lamp head, a first clamping part, a second clamping part, and a damping assembly. The lamp head is provided with a light source. The first clamping part has a first end and a second end, the first end being hinged to the lamp head, and the first clamping part is provided with a first circuit board, which is electrically connected to the light source. The second clamping part has a third end and a fourth end, the third end being hinged to the second end to close or open the first clamping part. The damping assembly includes a fixed shaft and an elastic ring rotatably connected to the fixed shaft. The fixed shaft is fixedly connected to the second end of the first clamping part, the elastic ring is disposed at the third end of the second clamping part, and a first positioning surface is provided on the outer periphery of the fixed shaft, the first positioning surface being located on the inner side of the cylindrical surface where the fixed shaft is located. The inner circumferential side of the elastic ring is provided with a second positioning surface, which is located inside the cylindrical surface of the inner cylinder where the elastic ring is located. The elastic ring is tightly fitted onto the fixed shaft and is used to provide damping for the relative rotation of the second clamping part and the first clamping part. When the second clamping part and the first clamping part are in the open state, the second positioning surface and the first positioning surface are offset from each other in the circumferential direction. When the second clamping part and the first clamping part are in the closed state, the second positioning surface and the first positioning surface cooperate with each other to provide a holding force to close the second clamping part and the first clamping part together. When the lamp is clamped on the screen of the electronic device, the first end abuts against the front side of the screen, and the fourth end abuts against the back of the screen.

[0005] The lamp according to the embodiment of this utility model has at least the following beneficial effects: The lamp includes a lamp head, a first clamping part, a second clamping part, and a damping assembly. The lamp head is provided with a light source. The first end of the first clamping part is rotatably connected to the lamp head, thereby realizing the opening or closing of the first clamping part and the lamp head. The third end of the second clamping part is rotatably connected to the second end of the first clamping part, thereby realizing the opening or closing of the second clamping part and the first clamping part. The damping assembly includes a fixed shaft at the second end and an elastic ring at the third end. The elastic ring is tightly fitted onto the fixed shaft to provide rotational damping for the first clamping part and the second clamping part. Thus, when the first end of the first clamping part abuts against the front side of the electronic device screen, the fourth end of the second clamping part abuts against the back side of the electronic device screen. Due to the damping effect of the damping assembly, the first clamping part and the second clamping part can remain relatively stationary, thereby fixing the electronic device... On the screen of the device, damage to the screen is avoided. Furthermore, since a first positioning surface is provided on the outer periphery of the fixed shaft, and a second positioning surface is provided on the inner cylindrical surface of the elastic ring, the first positioning surface is positioned inside the centerline relative to the cylindrical surface of the fixed shaft, and the second positioning surface is also positioned relative to the centerline relative to the inner cylindrical surface of the elastic ring. Thus, when the first and second clamping parts are in the open state, the first and second positioning surfaces are offset circumferentially. When the first and second clamping parts are closed, the first and second positioning surfaces can cooperate circumferentially, allowing the second clamping part to press against the first clamping part under the action of the second positioning surface on the elastic ring, providing a clamping force and ensuring that the first and second clamping parts can be tightly closed together. Therefore, the lamp of this application can be clamped and fixed to the screen of an electronic device, reducing clamping damage to the screen.

[0006] According to some embodiments of the present invention, both the first positioning surface and the second positioning surface are planar.

[0007] According to some embodiments of the present invention, the elastic ring includes an annular portion, the annular portion having a discontinuous opening.

[0008] According to some embodiments of the present invention, the elastic ring further includes a fixing part, which is connected to one end of the opening of the annular portion and is fixedly connected to the second clamping member.

[0009] According to some embodiments of the present invention, the second clamping part is provided with a first limiting part and a second limiting part inside. The first limiting part and the second limiting part are respectively provided on both sides of the rotation direction of the fixing part, so as to limit and fix the fixing part.

[0010] According to some embodiments of the present invention, a counterweight is also included, which is disposed within the second clamping part.

[0011] According to some embodiments of the present invention, the first clamping part is cuboid and includes a front plate and a bottom plate. The front plate is used to close with the lamp head, and the bottom plate is used to close with the second clamping part. One end of the front plate extends and protrudes from the bottom plate to form the front clamping part. When the lamp is clamped on the screen of the electronic device, the front clamping part abuts against the front side of the screen.

[0012] According to some embodiments of the present invention, the front clamping part is provided with an avoidance opening to facilitate opening the second clamping part.

[0013] According to some embodiments of the present invention, the lamp head includes a total internal reflection lens and a housing, with a light outlet at the bottom of the housing, and the light source is located on the side of the total internal reflection lens away from the light outlet.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] The following is for reference. Figures 1 to 4 This invention describes a lamp according to an embodiment of the present invention.

[0023] like Figures 1 to 3As shown, the lamp according to an embodiment of the present invention includes: a lamp head 100, a first clamping part 200, a second clamping part 300, and a damping assembly 400. The lamp head 100 is provided with a light source 110. The first clamping part 200 has a first end 201 and a second end 202. The first end 201 is hinged to the lamp head 100. The first clamping part 200 is provided with a first circuit board 210, which is electrically connected to the light source 110. The second clamping part 300 has a third end 301 and a fourth end 302. The third end 301 is hinged to the second end 202 to close or open the first clamping part 200. The damping assembly 400 includes a fixed shaft 410 and an elastic ring 420 rotatably connected to the fixed shaft 410. The fixed shaft 410 is fixedly connected to the second end 202 of the first clamping part 200. The elastic ring 420 is disposed at the third end 301 of the second clamping part 300. A first positioning surface 411 is provided on the outer periphery of the fixed shaft 410. The first positioning surface 411 is located inside the cylindrical surface of the fixed shaft 410. The inner circumferential side of the elastic ring 420 is provided with a corresponding second positioning surface 423. The second positioning surface 423 is located inside the cylindrical surface of the inner cylinder of the elastic ring 420. The elastic ring 420 is tightly fitted onto the fixed shaft 410 and is used to provide damping for the relative rotation of the second clamping part 300 and the first clamping part 200. When the second clamping part 300 and the first clamping part 200 are in the open state, the second positioning surface 423 and the first positioning surface 411 are offset from each other in the circumferential direction. When the second clamping part 300 and the first clamping part 200 are in the closed state, the second positioning surface 423 and the first positioning surface 411 cooperate with each other to provide a holding force that closes the second clamping part 300 and the first clamping part 200 together. When the lamp is clamped on the screen of the electronic device, the first end 201 abuts against the front side of the screen, and the fourth end 302 abuts against the back of the screen.

[0024] Understandably, this type of lamp includes a lamp holder 100, a first clamping part 200, a second clamping part 300, and a damping assembly 400. The lamp holder 100 is equipped with a light source 110. The first end 201 of the first clamping part 200 is rotatably connected to the lamp holder 100, thereby enabling the opening or closing of the first clamping part 200 and the lamp holder 100. The third end 301 of the second clamping part 300 is rotatably connected to the second end 202 of the first clamping part 200, thereby enabling the opening or closing of the second clamping part 300 and the first clamping part 200. The damping assembly 400... The device includes a fixed shaft 410 located at the second end 202 and an elastic ring 420 located at the third end 301. The elastic ring 420 is tightly fitted onto the fixed shaft 410 to provide rotational damping for the first clamping part 200 and the second clamping part 300. Thus, when the first end 201 of the first clamping part 200 abuts against the front side of the electronic device screen, the fourth end 302 of the second clamping part 300 abuts against the back side of the electronic device screen. Due to the damping effect of the damping assembly 400, the first clamping part 200 and the second clamping part 300 can remain relatively stationary. This secures the device to the screen of the electronic device while preventing damage to the screen. Furthermore, since the outer periphery of the fixed shaft 410 has a first positioning surface 411, and the inner cylindrical surface of the elastic ring 420 has a second positioning surface 423, the first positioning surface 411 is positioned inside the centerline relative to the cylindrical surface of the fixed shaft 410, and the second positioning surface 423 is also positioned relative to the centerline relative to the inner cylindrical surface of the elastic ring 420. Therefore, when the first clamping part 200 and the second clamping part 300 are in the open state, the first positioning surface 411 and the second positioning surface 423 are circumferentially aligned. The first clamping part 200 and the second clamping part 300 are in a staggered state. When the first clamping part 200 and the second clamping part 300 are closed, the first positioning surface 411 and the second positioning surface 423 can cooperate with each other in the circumferential direction. This allows the second clamping part 300 to be pressed against the first clamping part 200 under the action of the second positioning surface 423 on the elastic ring 420, so as to provide a clamping force and ensure that the first clamping part 200 and the second clamping part 300 can be closed with each other. Therefore, the lamp of this application can be clamped and fixed on the screen of electronic device and reduce clamping damage to the screen.

[0025] Specifically, the first clamping part 200 is also provided with a battery 240 for power supply, and the first circuit board 210 is electrically connected to the battery 240 and the light source 110 respectively.

[0026] It is understandable that both the first positioning surface 411 and the second positioning surface 423 are planar. For example, as... Figure 3As shown, in this embodiment, both the first positioning surface 411 and the second positioning surface 423 are planar. Therefore, when the first clamping part 200 and the second clamping part 300 are fully open, the first positioning surface 411 and the second positioning surface 423 are completely misaligned. At this time, only the frictional force generated by the clamping between the fixed shaft 410 and the elastic ring 420 provides rotational damping, so that the lamp can be fixedly clamped on the screen. When the second clamping part 300 and the first clamping part 200 rotate relative to each other and approach the closed state, the second positioning surface 423 and the first positioning surface 411 also gradually approach each other and generate an elastic restoring force that gradually aligns with each other, so that the second clamping part 300 can be easily closed. Since the second positioning surface 423 and the first positioning surface 411 are not in a completely aligned state when fully closed, they can always maintain a clamped state, so that the second clamping part 300 can always be tightly closed on the first clamping part 200.

[0027] It should be understood that in other embodiments, the first positioning surface 411 may also be a groove recessed toward the center line of the fixed shaft 410, and the second positioning surface 423 may also be a protrusion protruding toward the center line of the elastic member on the inner circumferential side of the elastic member, so that they can also play a role in cooperating with each other, so that after the second clamping part 300 and the first clamping part 200 are tightened, part of the protrusion enters into the groove, but does not completely enter the groove, so that there is always a holding force to keep the second clamping part 300 pressed against the first clamping part 200.

[0028] It is understood that the elastic ring 420 includes an annular portion 421, which has a discontinuous opening. For example, as Figure 3 As shown, in this embodiment, the elastic ring 420 includes an annular portion 421 with a broken opening, thereby making the annular portion 421 elastic.

[0029] It is understood that the elastic ring 420 also includes a fixing part 422, which is connected to one end of the opening of the annular part 421 and is fixedly connected to the second clamping member. For example, as Figure 3 As shown, in this embodiment, the fixing part 422 of the elastic ring 420 is connected to one end of the opening of the annular part 421, and is fixed in the second clamping member by the fixing part 422, thereby realizing the fixing of the elastic ring 420.

[0030] It is understood that the second clamping part 300 is internally provided with a first limiting part 310 and a second limiting part 320. The first limiting part 310 and the second limiting part 320 are respectively provided on both sides of the rotation direction of the fixing part 422 to limit and fix the fixing part 422. For example, as Figure 2As shown, in this embodiment, by providing a first limiting member and a second limiting member on both sides of the rotation direction of the fixing part 422 inside the second clamping part 300, the two sides of the rotation direction of the fixing part 422 are filled and fixed, thereby improving the consistency of the rotation of the second clamping part 300 and the elastic ring 420.

[0031] It is understandable that it also includes a counterweight 330, which is disposed within the second clamping part 300. For example, as Figure 2 As shown, in this embodiment, by providing a counterweight 330 inside the second clamping part 300, the stability of the lamp clamped on the screen is improved, and the lamp head 100 is prevented from being too heavy and tipping forward.

[0032] It is understood that the first clamping part 200 is cuboid in shape and includes a front plate 220 and a bottom plate 230. The front plate 220 is used to close with the lamp holder 100, and the bottom plate 230 is used to close with the second clamping part 300. One end of the front plate 220 extends and protrudes from the bottom plate 230 to form a front clamping part 221. When the lamp is clamped on the screen of an electronic device, the front clamping part 221 abuts against the front side of the screen. For example, as... Figures 1 to 2 As shown, in this embodiment, the first clamping part 200 is cuboid and includes a front plate 220 and a side plate. The bottom plate 230 is used to close with the second clamping part 300, the front plate 220 is used to close with the lamp head 100, and the portion of the front plate 220 extending out of the bottom plate 230 forms a front clamping part 221. The front clamping part 221 is used to abut against the front side of the screen, and the fourth end 302 is used to abut against the back of the screen, thereby achieving clamping and fixing on the screen.

[0033] Understandably, the front clamping part 221 is provided with a clearance opening 222 to facilitate opening the second clamping part 300. For example, as Figures 1 to 2 As shown, in this embodiment, the front clamping part 221 of the front plate 220 extending beyond the bottom is provided with a clearance opening 222. Thus, when it is necessary to open the second clamping member and the first clamping member which are in a closed state, the user can hold the fourth end 302 of the second clamping part 300 through the clearance opening 222 and rotate it to achieve the opening effect. This can both achieve clamping and fixation and facilitate the opening of the second clamping part 300.

[0034] It is understood that the lamp holder 100 includes a total internal reflection lens 120 and a housing 130, with a light outlet 133 at the bottom of the housing 130. The light source 110 is located on the side of the total internal reflection lens 120 away from the light outlet 133. For example, as Figures 1 to 2 As shown, in this embodiment, the light source 110 of the lamp head 100 is emitted from the light outlet 133 at the bottom of the housing 130 through the total internal reflection lens 120, thereby ensuring that the emitted light is uniform and has high brightness.

[0035] It is understood that the housing 130 includes a base 131 and an upper housing 132. The base 131 is hinged to the second end 202. The base 131 has an opening at the top and a light outlet 133 at the bottom. The upper housing 132 is cuboid with an opening at the bottom for fitting onto the base 131. For example, as... Figures 1 to 4 As shown, in this embodiment, the housing 130 is configured as a base 131 and an upper shell 132 fitted onto the base 131, thereby ensuring that the assembled housing 130 presents a cuboid shape. Thus, in the closed state, the lamp head 100, the first clamping part 200 and the second clamping part 300 together form a cuboid with a smooth and beautiful surface, and are convenient for storage and carrying.

[0036] Specifically, the base 131 is hinged to the second end 202. The base 131 has an opening at the top and a light outlet 133 at the bottom so that the light source 110 emits light from the bottom light outlet 133.

[0037] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
