[0034] The core of the utility model is to disclose a lamp with an opening and closing mechanism, which has high control accuracy and low risk of parts getting stuck during the movement process.

[0035] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0036] See also Figure 1-14The embodiment of the utility model introduces a lamp with an opening and closing mechanism in detail. The core of the lamp is an innovative opening and closing mechanism. The efficient use and maintenance of the lamp are achieved through the coordinated work of the bracket 10, the light source assembly 20 and the opening and closing member 30. Specifically, the bracket 10 is used as a supporting structure for the light source assembly 20 and the opening and closing member 30. It is preferably made of high-strength material to ensure the stability and durability of the overall structure. A screw 40 is provided on the bracket 10. After receiving power input, the screw 40 rotates at the protruding portion of the bracket 10 surface, and the opening and closing member 30 is hinged to the bracket 10. On the bracket 10, it should be noted that the opening and closing member 30 includes a connecting end and an action end. The connecting end is an end that is in direct contact with the screw 40 to obtain power input during the rotation of the screw 40, and the action end is an end away from the screw 40. The hinge point is set between the connecting end and the action end of the opening and closing member 30, so that when the connecting end obtains power input and moves, the opening and closing member 30 rotates along its hinge point to drive the action end to rotate closer to or away from the screw 40; the light source assembly 20 is fixed on the bracket 10, and it can use high-efficiency LED lamp beads to achieve the purpose of energy saving and environmental protection while ensuring the lighting effect.

[0037] On the basis of the above structure, the opening and closing member 30 will at least pass through the first position and the second position during the rotation process along the hinge point. When the opening and closing member 30 is rotated to the first position, it can completely enclose the light source assembly 20. When the lamp does not need lighting or viewing, the opening and closing member 30 is rotated to the first position to effectively prevent external dust, moisture and other factors from damaging the light source assembly 20, thereby extending the service life of the light source assembly 20; and when the opening and closing member 30 is rotated to the second position, the opening and closing member 30 is opened to expose the light source assembly 20 to realize the lighting of the lamp, or to create a viewing atmosphere of the lamp being unfolded during the opening process; the above structure not only improves the practicality of the lamp, but also enhances its aesthetics, so that the lamp presents a simple appearance when it is closed, and a bright and spacious lighting effect when it is turned on.

[0038] The lamp with an opening and closing mechanism provided by the embodiment of the utility model hinges the opening and closing member 30 on the bracket 10, so as to achieve the purpose of enclosure and closure during the rotation of the opening and closing member 30 along its hinge point, and to open and expose the light source assembly 20. The light source assembly 20 is protected when the lamp does not need lighting, and is exposed when lighting is needed. At the same time, the opening speed of the opening and closing member 30 can also be controlled to create an atmosphere of viewing in which the lamp is slowly unfolded and lit. The opening and closing member 30 is driven by a screw rod 40 provided through the bracket 10. The screw rod 40 is directly connected to the connecting end on the opening and closing member 30 to directly transmit the opening and closing member 30 without the need for other transmission components. That is, the rotation transmission of the opening and closing member 30 in the present application is a single-stage transmission, which can not only improve the control accuracy of the opening and closing member 30, but also reduce the risk of stuck components on the transmission chain due to the small number of components in the transmission process.

[0039] Furthermore, in the process of the opening and closing member 30 being driven by the screw 40 to move, the opening and closing member 30 can be pushed and pulled by changing the position of the screw 40 in its axial direction to drive the opening and closing member 30 to move. In order to improve the stability and uniformity of the rotation process of the opening and closing member 30, in some embodiments of the utility model, the opening and closing member 30 is specifically composed of a shielding part 310 and a gear part 320, which are respectively arranged on both sides of the hinge. The gear part 320 is in direct contact with and meshing with the outer wall of the screw 40. During the rotation process, the screw 40 will drive the gear part 320 to rotate, and then drive the shielding part 310 on the other side of the hinge to rotate to perform the action of shielding or exposing the light source assembly 20. The setting of the gear part 320 can achieve the transmission effect of the screw drive with the screw 40, thereby improving the stability and reliability of the movement of the opening and closing member 30.

[0040] On the basis of the above embodiment, the gear portion 320 is designed to be an arc-shaped configuration, so that the gear portion 320 always maintains a meshing state with the outer wall of the screw 40 during the rotation process, which not only improves the continuity and stability of the transmission process, but also helps to reduce the wear caused by uneven contact between the gear and the screw 40, thereby extending the service life of the gear. In addition, the arc-shaped gear portion 320 is also more visually harmonious, complementing the overall shape of the opening and closing member 30, and enhancing the structural refinement of the lamp.

[0041] Furthermore, in the lamp with an opening and closing mechanism provided in the embodiment of the utility model, the hinge between the opening and closing member 30 and the bracket 10 is realized by the rotating shaft 340. Specifically, a through connecting hole 330 is provided on the opening and closing member 30, and a rotating shaft 340 is passed through the connecting hole 330 to allow the opening and closing member 30 to remain stable during rotation and reduce vibration or noise caused by unstable connection. Correspondingly, a support seat 50 with a sleeve 510 is also fixedly provided on the bracket 10. The support seat 50 is fixedly connected to the bracket 10 by screws to maintain a stable supporting effect. The sleeve 510 takes into account wear resistance and the ability to fix the rotating shaft 340 to ensure the stable rotation effect of the rotating shaft 340 in the support seat 50. The rotating shaft 340 passes through the connecting hole 330 and the sleeve 510, which not only simplifies the installation process of the opening and closing member 30, but also improves the installation accuracy.

[0042] On the basis of the above embodiment, in order to further improve the rotation stability of the opening and closing member 30, a single opening and closing member 30 is matched with two parallel and spaced support seats 50. Specifically, after the rotating shaft 340 passes through the connecting hole 330, both ends are respectively extended into a shaft sleeve 510 to ensure that the rotating shaft 340 is evenly distributed between the two support seats 50, thereby providing better support when the opening and closing member 30 rotates. The rotating shaft 340 with both ends extending into the shaft sleeve 510 has better support stability, can effectively disperse the load, and reduce the stress concentration of a single support point, thereby improving the durability of the opening and closing member 30.

[0043] It should be noted that the opening and closing member 30 can also be set as a U-shaped structure and have two connecting holes 330, so that the two ends of the rotating shaft 340 extend into a connecting hole 330 respectively, and the support seat 50 can be set as a single one, so that the middle area of ​​the rotating shaft 340 passes through the shaft sleeve 510 to realize the hinged setting of the opening and closing member 30 on the bracket 10.

[0044] The bracket 10 serves as a supporting structure for the opening and closing parts 30 and the light source assembly 20. The structural stability of the bracket 10 is of great significance to the service life and component arrangement of the lamp. In a specific embodiment of the utility model, the design of the bracket 10 adopts a disc configuration. The disc-structured bracket 10 is not only beautiful, but also the components arranged on the upper part have a compact structure, which is beneficial to improving the space utilization of the overall lamp and maintaining a close fit of the components. The screw 40 is arranged through the center of the disc so that other components, such as the opening and closing parts 30, can be evenly arranged in the surrounding area of ​​the screw 40. In particular, when multiple opening and closing parts 30 are arranged in the circumferential direction, it can be ensured that the rotation radius of each opening and closing part 30 is the same, thereby achieving a more coordinated and consistent opening and closing action.

[0045] On the basis of the above embodiment, the number of opening and closing members 30 is preferably set to three, and the three opening and closing members 30 are evenly arranged in the circumferential direction of the screw 40. The three opening and closing members 30 can cooperate with each other to avoid the problem of a single opening and closing member 30 being too large when the light source assembly 20 needs to be shielded. At the same time, the uniform distribution of the three opening and closing members 30 enables each opening and closing member 30 to obtain the same torque when rotating, thereby achieving a smoother and more precise opening and closing action; in addition, the design of the three opening and closing members 30 also takes into account the lighting range and effect of the lamp. Through the evenly distributed opening and closing members 30, a more uniform lighting effect can be achieved, avoiding lighting blind spots or uneven brightness caused by uneven distribution of the opening and closing members 30.

[0046] Further, in the lamp with an opening and closing mechanism provided in the embodiment of the utility model, the screw 40 is used to receive power input and transmit it to the opening and closing member 30 to drive the opening and closing member 30 to rotate, and the power input to the screw 40 can be through a variety of ways such as manual twisting and electric drive. In a specific embodiment of the utility model, the lamp also includes a motor 60 and a support 610, so that the screw 40 is driven to rotate by the motor 60. Specifically, the action end of the motor 60 is directly connected to the screw 40, so that the screw 40 is driven to rotate by the rotation of the motor 60, thereby realizing the automatic opening and closing of the opening and closing member 30. The motor 60 is configured to be fixed on the support 610, and the support 610 is provided with a plurality of screw holes for fixedly connecting with the surrounding structural parts in the lamp by screws. The support 610 can realize the stable setting of the motor 60 and absorb part of the vibration during the movement of the motor 60, so as to avoid the damage of the motor 60 to other parts in the lamp. The setting of the motor 60 not only simplifies the user's operation process, but also improves the intelligence level of the lamp. Furthermore, the user can control the motor 60 through a remote control or a smart device to realize functions such as remote control and timing control, thereby improving the user experience.

[0047] In order to further improve the service life of the lamp, in some embodiments of the present invention, the lamp also includes a shell 70, and the bracket 10 is fixed to the bottom of the shell 70 by screws. It should be noted that the depth of the shell 70 is greater than the setting height of the bracket 10 relative to the bottom of the shell 70, so that the shell 70 can not only provide sufficient setting space for the bracket 10 and internal components, but also facilitate heat dissipation and noise reduction, and can play a certain role in enclosing and protecting the bracket 10 and the components arranged on the bracket 10.

[0048] Furthermore, in some embodiments of the utility model, the light source assembly 20 is designed to be cylindrical in configuration so as to have a good appearance effect, and can achieve different lighting requirements through the cylindrical structure, such as downlights or spotlights, and at the same time, the light source assembly 20 has three connecting claws 210 evenly extending in its circumference, and each connecting claw 210 has a hole so as to be fixedly connected to the base 110 protruding from the bracket 10 through screws. The setting of the three connecting claws 210 can ensure the setting stability of the cylindrical structure of the light source assembly 20, and the base 110 protruding from the bracket 10 can create a certain space between the light source assembly 20 and the bracket 10 for wiring or setting other components, thereby improving the space utilization on the bracket 10.

[0049] It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other.
