Description

Technical Field

[0001] This utility model relates to the field of outdoor lighting technology, specifically a height-adjustable lighting structure. Background Technology

[0002] Outdoor sunshade devices (such as parasols and awnings) are widely used in various outdoor scenarios, providing not only sun protection but also wind and rain protection. Some outdoor sunshade devices include lighting for convenient nighttime use; however, existing lighting devices have fixed positions. For example, patent application CN202420903316.0, entitled "Shared Smart Sunshade Umbrella," discloses a sunshade umbrella with an LED light at the bottom of the sliding tube, using the LED as a light source. However, once the umbrella is open, the position of the sliding tube is fixed, and the LED light at the bottom of the tube also remains stationary. This fails to meet the usage habits and needs of different users, therefore, the lighting structure of existing outdoor sunshade devices needs further improvement. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a simple, reasonable and easy-to-use adjustable lighting structure that can better meet the usage habits and needs of different users by raising and lowering the position of the light source.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A liftable lighting structure includes a lighting device with a light source inside. The lighting device is mounted on the sunshade device via a lifting mechanism, allowing the light source to be positioned closer to or further away from the sunshade device.

[0006] Further optimization measures for this technical solution are as follows:

[0007] As an improvement, the lifting mechanism includes a base and a telescopic assembly. The telescopic assembly is composed of nested, telescopic cylindrical tubes, and the upper end of each cylindrical tube is provided with a limiting edge. The lighting device is provided with a winding wheel connected to the driving device. A pulling rope is wound on the winding wheel, and the upper end of the pulling rope is fixed to the base.

[0008] As an improvement, the lifting mechanism includes a base and a telescopic assembly. The telescopic assembly is composed of successively telescopic nested conical cylinders. The lighting device is equipped with a winding wheel connected to the driving device. A pull rope is wound on the winding wheel, and the upper end of the pull rope is fixed to the base.

[0009] As an improvement, the lifting mechanism includes a base and a telescopic assembly. The telescopic assembly is composed of continuous X-shaped splicing parts, with the two ends of adjacent X-shaped splicing parts respectively hinged to form a rhombus structure. The X-shaped splicing parts are composed of two splicing rods hinged in the middle. The lighting device is equipped with a winding wheel connected to the driving device. A pulling rope is wound on the winding wheel, and the upper end of the pulling rope is fixed to the base.

[0010] The lifting mechanism uses electric lifting. When rising, the drive device drives the winding wheel to rotate, thereby winding the pull rope onto the winding wheel to reduce the length of the unwound pull rope and pull the lighting device upward. When descending, the drive device rotates in the opposite direction to release the pull rope, and the lighting device descends under the action of gravity.

[0011] As an improvement, the lifting mechanism includes a base and a telescopic assembly. The telescopic assembly is composed of nested cylindrical tubes that extend and retract sequentially. Adjacent cylindrical tubes are interference-fitted, and the upper end of each cylindrical tube is provided with a limiting edge.

[0012] As an improvement, the lifting mechanism includes a base and a telescopic assembly, the telescopic assembly being composed of successively telescopic nested conical cylinders, with an interference fit between adjacent conical cylinders.

[0013] As an improvement, the lifting mechanism includes a base and a telescopic assembly. The telescopic assembly is composed of continuous X-shaped splicing parts, with the two ends of adjacent X-shaped splicing parts respectively damped and hinged to form a rhombus structure. The X-shaped splicing parts are composed of two splicing rods hinged in the middle.

[0014] The lifting mechanism can also be manually lifted, using the friction generated by the interference fit between the parts to keep the lighting device in a certain position when there is no external force, and to raise or lower the lighting device when an external force is applied.

[0015] As an improvement, a lighting lamp is provided at the lower part of the lighting device, and a light-transmitting cover is provided around the lighting lamp. The light-transmitting cover can provide a certain degree of protection for the internal lighting lamp.

[0016] As an improvement, the upper part of the lighting device is equipped with a spotlight, and the outer cover of the spotlight is equipped with a projection cover. The projection cover is decorated with a pattern, and under the illumination of the spotlight, the pattern on the projection cover is projected onto the sunshade of the sunshade device, thereby achieving the purpose of projection decoration.

[0017] As an improvement, a transparent protective cover is provided outside the projection dome. The transparent protective cover can protect the projection dome and the spotlights inside.

[0018] The advantages of this utility model compared with the prior art are:

[0019] This utility model discloses a height-adjustable lighting structure, which is simple, reasonable, and easy to use. Through the lifting mechanism, the lighting device can be raised or lowered, thereby achieving the purpose of moving the light source closer to or further away from the sunshade.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings:

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0034] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0036] Example 1, as Figures 1 to 4 As shown, a liftable lighting structure includes a lighting device 1, which contains a light source. The lighting device 1 is mounted on the sunshade device 2 via a lifting mechanism so that the light source can be positioned close to or away from the sunshade 21 of the sunshade device 2.

[0037] The aforementioned sunshade device 2 can be a parasol, awning, etc.

[0038] In this embodiment, an electric lifting structure is adopted, the sunshade device 2 is a sun umbrella, and the sunshade material 21 is the umbrella surface. The lifting mechanism includes a base 3 and a telescopic assembly 4. The telescopic assembly 4 is composed of successively telescopic nested cylindrical tubes 41, and the upper end of each cylindrical tube 41 is provided with a limiting edge 41a. The lighting device 1 is provided with a winding wheel 6 connected to the driving device 5. A pull rope 7 is wound on the winding wheel 6, and the upper end of the pull rope 7 is fixed to the base 3. The base 3 is fixed to the center of the sun umbrella, and the two ends of the telescopic assembly 4 are respectively connected to the base 3 and the lighting device 1. The limiting edge 41a can prevent the cylindrical tubes 41 from separating from each other.

[0039] The aforementioned drive device 5 is preferably a motor. A telescopic column structure is formed by successively telescopically nested cylindrical tubes 41, with the diameter of each tube decreasing from top to bottom. When the lighting device 1 needs to rise, the motor starts, driving the winding wheel 6 to rotate, thereby winding the pull rope 7 onto the winding wheel 6. The length of the unwound portion of the pull rope 7 decreases, and the upper end of the pull rope 7 is fixed to the base 3. As the pull rope 7 is wound, an upward force is generated, pulling the lighting device 1 upward, thus achieving the purpose of raising the lighting device 1. When the lighting device 1 needs to descend, the motor rotates in the opposite direction, driving the winding wheel 6 to rotate and releasing the pull rope 7 wound on the winding wheel 6. The length of the unwound portion of the pull rope 7 increases, the upward pulling force disappears, and under the action of gravity, the lighting device 1 naturally descends.

[0040] The lighting device 1 is equipped with both a main light 11 and a projection light. The main light 11 is located at the lower part of the lighting device 1, and a light-transmitting cover 12 is installed around the main light 11. The spotlight 13 is located at the upper part of the lighting device 1, and a projection cover 14 is installed around the spotlight 13. A transparent protective cover 15 is installed around the projection cover 14.

[0041] The lower lighting lamp 11 is mainly used for lighting, while the upper spotlight 13 can project the pattern on the projection cover 14 onto the inner surface of the umbrella. The projection lamp can be used to decorate the sunshade device 2 and can also project some slogans onto the umbrella.

[0042] The lighting structure applied to the sunshade device 2 of this invention uses a lifting mechanism to allow the light source to move closer to or further away from the sunshade object 21 of the sunshade device 2. Once the sunshade device 2 is installed, the height of the sunshade object 21 from the ground is fixed. By adjusting the distance between the light source and the sunshade object 21, the distance between the light source and the ground, or the distance between the light source and the user, can be adjusted to meet the usage habits and needs of different users. Furthermore, adjusting the distance between the light source and the sunshade object 21 can also adjust the projection effect, making the projection effect more refined.

[0043] Example 2, as Figures 5 to 6 As shown, in this embodiment, electric lifting is also used, and its structure is similar to that of Embodiment 1. The difference lies in the structure of the telescopic component 4. Specifically, in this embodiment, the lifting mechanism includes a base 3 and a telescopic component 4. The telescopic component 4 is composed of successively telescopic nested conical cylinders 42. The lighting device 1 is equipped with a winding wheel 6 connected to the driving device 5. A pull rope 7 is wound on the winding wheel 6, and the upper end of the pull rope 7 is fixed to the base 3. The bottom circle diameter of the conical cylinders 42 decreases from top to bottom. The characteristic of one end being larger than the other end of the conical cylinders 42 forms a limit between adjacent conical cylinders 42, preventing adjacent conical cylinders 42 from detaching.

[0044] Example 3, as Figure 7 As shown, the same electric lifting mechanism is used, and its structure is similar to that of Embodiment 1. The difference lies in the structure of the telescopic component 4. Specifically, in this embodiment, the lifting mechanism includes a base 3 and a telescopic component 4. The telescopic component 4 is composed of continuous X-shaped splicing parts 43. The two ends of adjacent X-shaped splicing parts 43 are hinged to form a rhombus structure. The X-shaped splicing parts 43 are composed of two splicing rods hinged in the middle. The lighting device 1 is equipped with a winding wheel 6 connected to the driving device 5. A pull rope 7 is wound on the winding wheel 6, and the upper end of the pull rope 7 is fixed to the base 3. The continuous X-shaped splicing parts 43 are connected to form a continuous rhombus structure. The telescopic component 4 is extended and retracted by the deformation of the rhombus structure, thereby realizing the lifting and lowering of the lighting device 1.

[0045] Example 4, as Figure 8 As shown, a manual lifting structure is adopted, and its telescopic structure is similar to that of Embodiment 1. The difference is that the electric structure (drive device 5, winding wheel 6, and pull rope 7) of Embodiment 1 is omitted in this embodiment. Specifically, in this embodiment, the lifting mechanism includes a base 3 and a telescopic component 4. The telescopic component 4 is composed of successively telescopic nested cylindrical tubes 41, with an interference fit between adjacent cylindrical tubes 41. The upper end of each cylindrical tube 41 is provided with a limiting edge 41a. The friction generated by the interference fit keeps the telescopic component 4 in a fixed state when no external force is applied. When the lighting device 1 needs to be raised or lowered, the user only needs to manually stretch or compress the telescopic component 4.

[0046] Example 5, as Figure 9 As shown, a manual lifting structure is adopted, and its telescopic structure is similar to that of Embodiment 2. The difference is that the electric structure in Embodiment 2 is omitted in this embodiment. Specifically, in this embodiment, the lifting mechanism includes a base 3 and a telescopic component 4. The telescopic component 4 is composed of successively telescopic nested conical cylinders 42, with an interference fit between adjacent conical cylinders 42. Similarly, the frictional force generated by the interference fit between adjacent conical cylinders 42 causes the telescopic component 4 to extend and retract under the action of external force, thereby realizing the manual lifting and lowering of the lighting device 1.

[0047] Example 6, as Figure 10As shown, a manual lifting structure is also adopted, and its telescopic structure is similar to that of Embodiment 3. The difference is that the electric structure in Embodiment 3 is omitted in this embodiment. Specifically, in this embodiment, the lifting mechanism includes a base 3 and a telescopic component 4. The telescopic component 4 is composed of continuous X-shaped splicing parts 43. The two ends of adjacent X-shaped splicing parts 43 are respectively damped and hinged to form a rhomboid structure. The X-shaped splicing parts 43 are composed of two splicing rods hinged in the middle. The damped hinge allows the connection to maintain a certain angle when no external force is applied. When the lighting device 1 needs to be raised or lowered, the user only needs to manually stretch or compress the telescopic component 4 to extend or retract it, thereby realizing the manual raising and lowering of the lighting device 1.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
