Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and in particular, to a magnet assembly, a lamp sticker and a ceiling lamp. Background Art

[0002] A ceiling lamp is the most common lighting fixture for indoor lighting. Due to its characteristics of not occupying space and being closer to natural lighting, it is widely used for lighting in areas such as living rooms, bedrooms, kitchens or corridors. Generally, a ceiling lamp includes a base, a lamp sticker and a lampshade; the base is fixedly installed on the ceiling; the lamp sticker includes an optoelectronic component and a magnet assembly. One end of the magnet assembly is fixedly connected to the optoelectronic component, and the other end is provided with a magnet block, which is adsorbed and connected to the base; the lampshade is arranged on the side of the lamp sticker away from the base.

[0003] The prior art provides a magnet assembly, as Figure 1 shown, including a fixed column 01 and a magnet block 02. One end ( Figure 1 the lower end in

[0004] ) of the fixed column 01 is provided with a mounting groove adapted to the magnet block 02, and the magnet block 02 is embedded in the mounting groove. Among them, the fixed column 01 is made of a ferromagnetic material (a material that can be attracted by a magnet), such as stainless steel; the magnet block 02 is adsorbed and connected to the fixed column 1. Figure 2 In order to realize the automatic assembly of the magnet assembly and the optoelectronic component, it is necessary to stack a plurality of magnet assemblies neatly in a customized sleeve 03; among them, neat stacking means that the central axes of a plurality of magnet assemblies are on the same straight line. When the magnet assembly is loaded into the sleeve 03, the sleeve 03 is placed vertically, and the magnet assemblies can be neatly stacked in the sleeve 03. However, during transfer, transportation or installation, the sleeve 03 may be collided or toppled, resulting in eccentricity of a plurality of magnet assemblies (as shown in

[0005] ), that is, the central axes of a plurality of magnet assemblies are not on the same straight line. Even if the sleeve 03 is repositioned to the vertical state, due to the attractive force between adjacent magnet assemblies, it is very difficult for the magnet assemblies to return to the coaxial state. As a result, the magnet assemblies in the sleeve 03 cannot be used in automated equipment, which hinders the automated assembly process of the lamp sticker. If you still want to use automated equipment to assemble the magnet assembly, it is necessary to take out the magnet assembly from the sleeve 03 and then refill it, and the assembly efficiency of the lamp sticker is low.

[0006] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0007] On the one hand, an embodiment of the present invention provides a magnet assembly, including a fixing post and a magnet block; a butting protrusion is provided on the end face of the first end of the fixing post, the central axis of the butting protrusion coincides with the central axis of the fixing post, an installation groove is provided on the end face of the second end of the fixing post, and the fixing post is made of a ferromagnetic material; the magnet block is embedded in the installation groove, and the projection of the butting protrusion on the end face of the second end of the fixing post is within the projection range of the magnet block on the second end face.

[0008] Optionally, the radial cross-section of the butting protrusion is a centrally symmetric figure, and the center of rotational symmetry of the radial cross-section of the butting protrusion is located on the central axis of the fixing post.

[0009] Optionally, the radial cross-section of the butting protrusion is an annular shape.

[0010] Optionally, the butting protrusion includes a plurality of protruding points, and the plurality of protruding points are evenly distributed around the central axis of the fixing post.

[0011] Optionally, the height of the butting protrusion is 0.3 to 0.5 millimeters.

[0012] Optionally, the fixing post is provided with a through hole, the central axis of the through hole coincides with the central axis of the fixing post, and the diameter of the through hole is smaller than the diameter of the installation groove.

[0013] For the magnet assembly provided by the embodiment of the present invention, a butting protrusion is provided on the end face of the fixing post away from the magnet block, and the radial cross-sectional area of the butting protrusion is smaller than the radial cross-sectional area of the magnet block. When two adjacent magnet assemblies are stacked, one is the upper magnet assembly and the other is the lower magnet assembly; the lower magnet assembly first falls into the sleeve, and when the upper magnet assembly falls into the sleeve from top to bottom, the magnet block of the upper magnet assembly abuts against the butting protrusion of the lower magnet assembly. When the magnet block abuts against the butting protrusion, the magnetic flux of the magnet block gathers towards the butting protrusion, thereby increasing the attraction force at the contact surface of the two magnet assemblies; that is, the attraction force between the magnet block and the butting protrusion is enhanced. The attraction force in the middle area between the two magnet assemblies is greater than the attraction force in the surrounding area, enhancing the ability of the magnet assembly to resist external force impacts. Even if the sleeve is collided or tilted, it is not easy for the two adjacent magnet assemblies to be eccentric, reducing the possibility of eccentricity, enabling the magnet assemblies in the sleeve to be used in the automated assembly equipment of the lamp sticker, and the magnet assemblies will not be stuck by the automated assembly equipment, thereby improving the assembly efficiency of the lamp sticker.

[0014] On the other hand, an embodiment of the present invention further provides a lamp sticker, including an optoelectronic component and the magnet assembly of any one of the above, and the magnet assembly is fixedly connected to the optoelectronic component.

[0015] Optionally, a limiting flange extending away from the central axis of the fixing post is provided at the first end of the fixing post, and a mounting hole adapted to the fixing post is provided on the optoelectronic component; the second end of the fixing post extends into the mounting hole, and the limiting flange abuts against the optoelectronic component.

[0016] The lamp sticker according to the embodiment of the present invention can avoid the eccentricity problem of multiple magnet components in the sleeve due to the adoption of the magnet component in the above embodiment, thereby improving the assembly efficiency of the lamp sticker.

[0017] On the other hand, an embodiment of the present invention further provides a ceiling lamp including the above lamp sticker.

[0018] The ceiling lamp provided by the embodiment of the present invention can improve the assembly speed of the ceiling lamp due to the adoption of the lamp sticker in the above embodiment. Description of the Drawings

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mounting", "connecting", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. It may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] An embodiment of the present invention provides a magnet assembly. Refer to Figure 3 、Figure 4 and Figure 5 , including a fixing column 1 and a magnet block 2; a butting protrusion 11 is provided on the first end face 1a of the fixing column 1, the central axis of the butting protrusion 11 coincides with the central axis of the fixing column 1, and an installation groove 12 is provided on the second end face 1b of the fixing column 1; the magnet block 2 is embedded in the installation groove 12, and the projection of the butting protrusion 11 on the second end face 1b of the fixing column 1 is within the projection range of the magnet block 2 on the second end face 1b; wherein, the fixing column 1 is made of a ferromagnetic material. It should be understood that the "central axis" refers to the connection line of the circumcenter of the outer contour of the radial ( Figure 5 horizontal direction in) cross-section.

[0038] The magnet assembly provided by the embodiment of the present invention, referring to Figure 5 and Figure 7 , a butting protrusion 11 is provided on the end face 1a of the fixing column 1 away from the magnet block 2, and the radial cross-sectional area of the butting protrusion 11 is smaller than the radial cross-sectional area of the magnet block 2. When two adjacent magnet assemblies are stacked, the lower magnet assembly first falls into the sleeve 100. When the upper magnet assembly falls into the sleeve 100 from top to bottom, the magnet block 2 of the upper magnet assembly abuts against the butting protrusion 11. When the magnet block 2 abuts against the butting protrusion 11, the magnetic flux of the magnet block 2 gathers at the butting protrusion 11, increasing the attraction force at the contact surface of the two magnet assemblies; that is, the attraction force between the magnet block 2 and the butting protrusion 11 is enhanced. The attraction force in the middle area of the two magnet assemblies is greater than that in the peripheral area; enhancing the ability of the magnet assembly to resist external force impact, even if the sleeve 100 is collided or tilted, it is not easy for two adjacent magnet assemblies to be eccentric, reducing the possibility of eccentricity, enabling the magnet assembly in the sleeve to be used in the automatic assembly equipment of the lamp sticker, and the magnet assembly will not be stuck by the automatic assembly equipment, thereby improving the assembly efficiency of the lamp sticker.

[0039] It should be noted that in the prior art, referring to Figure 2 , when multiple magnet assemblies are stacked, the contact surface between two adjacent magnet assemblies is larger than the surface of the magnet block 02, the magnetic flux of the magnet block 02 is dispersed at the circumferential edge of the magnet block 02, and the gravitational force between the magnet block 02 of two adjacent magnet assemblies and the fixing column 01 is dispersed at the edge of the magnet block 02 (the magnetic flux is evenly distributed circumferentially along the surface of the magnet block 02), resulting in the attraction force between the two magnet assemblies being dispersed at the periphery of the magnet block 02. When multiple magnet assemblies are stacked, the ability of the magnet assembly to resist eccentricity is weak. When the sleeve 03 is collided or tilted, the magnet assembly is very easy to be eccentric. Compared with the prior art, in this application, referring to Figure 7, by means of the abutting protrusion 11, the contact surface area between two adjacent magnet components is reduced, and the contact surface of the two magnet components is arranged in the central region of the surface of the magnet block, increasing the magnetic flux in the central region of the magnet block and enhancing the attraction force in the central region between two adjacent magnet components, thereby enhancing the ability of the magnet component to resist eccentricity, reducing the possibility of eccentricity of the magnet component, and improving the assembly efficiency of the lamp sticker.

[0040] The fixing post 1 is made of a ferromagnetic material. The magnet block 2 is magnetically adsorbed and connected to the fixing post 1. The installation of the magnet block 2 and the fixing post 1 is convenient, which is beneficial to improving the assembly efficiency of the magnet component.

[0041] In some embodiments, referring to Figures 8 to 11 , the radial cross-section of the abutting protrusion 11 is a centrally symmetric figure, and the center of rotational symmetry of the radial cross-section of the abutting protrusion 11 is located on the central axis of the fixing post 1; in this embodiment, when multiple magnet components are stacked, the upper magnet component has higher stability and is not prone to tilting. It should be understood that the "radial cross-section" refers to the cross-section perpendicular to the central axis direction.

[0042] It should be noted that in some other embodiments, the radial cross-section of the abutting protrusion 11 may also be a non-centrally symmetric figure. Exemplarily, the radial cross-section of the abutting protrusion 11 may also be, for example, a trapezoid or other shapes, and as long as the central axis of the abutting protrusion 11 coincides with the central axis of the fixing post 1, the upper magnet component will not tilt under the action of gravity when multiple magnet components are stacked. When the radial cross-section of the abutting protrusion 11 is a centrally symmetric figure, the upper magnet component has higher stability; therefore, it should be understood that "the radial cross-section of the abutting protrusion 11 is a centrally symmetric figure" is only a preferred embodiment, rather than the only feasible embodiment.

[0043] In some embodiments, referring to Figure 8 , the radial cross-section of the abutting protrusion 11 is annular. The structure of the abutting protrusion 11 is simple, easy to manufacture, and has lower cost. It should be understood that if a through hole 13 is provided on the surface of the first end face 1a of the fixing post 1, the abutting protrusion 11 can only be a circular ring. If no through hole 13 is provided inside the fixing post 1, the abutting protrusion 11 can also be a cylinder, which will not be elaborated here.

[0044] In some embodiments, referring to Figures 9 to 11 , the abutting protrusion 11 includes a plurality of protruding points 11a, and the plurality of protruding points 11a are evenly distributed around the central axis of the fixing post 1. Exemplarily, the protruding point 11a can be circular (as shown in Figure 9 ), a partial circular ring (a small section of circular ring as shown in Figure 10 ), rectangular, triangular, or any other shape (as shown in Figure 11 ), which is not specifically limited here.

[0045] In some embodiments, the height of the abutting protrusion 11 is 0.3 to 0.5 millimeters; wherein, the height of the abutting protrusion 11 refers to the dimension of the abutting protrusion 11 along the direction perpendicular to the end face 1a of the first end of the fixing post 1. If the height of the abutting protrusion 11 is too large, it will not only occupy space but also cause material waste; if the height of the abutting protrusion 11 is too small, the attraction between the magnet block 2 and the end face 1a of the first end of the fixing post 1 is large, which affects the attraction between the magnet block 2 and the contact protrusion 1. It should be understood that "the height of the abutting protrusion 11 is 0.3 to 0.5 millimeters" is only a preferred embodiment, rather than the only embodiment.

[0046] In some embodiments, referring to Figure 5 , the fixing post 1 is provided with a through hole 13, the central axis of the through hole 13 coincides with the central axis of the fixing post 1, and the diameter of the through hole 13 is smaller than the diameter of the mounting groove 12; at this time, the limiting protrusion 11 is arranged around the through hole 13 on the end face 1a of the first end of the fixing post 1. The fixing post 1 is usually made of iron or iron alloy, which is convenient for the adsorption connection between the magnet block 2 and the fixing post 1; in this embodiment, setting a through hole on the fixing post 1 can reduce the weight of the fixing post 1, while reducing the material usage of the fixing post 1 and lowering the manufacturing cost of the magnet assembly 1.

[0047] It should be noted that, in some other embodiments, referring to Figure 6 , a groove 14 can also be provided on the bottom surface of the mounting groove 12 to replace the through hole 13 in the above embodiment, so as to avoid the through hole 13 affecting the setting of the abutting protrusion 11. The specific structure of the groove 14 (such as the radial cross-sectional shape and depth) is not specifically limited herein.

[0048] On the other hand, the embodiment of the present invention also provides a lamp sticker, which includes a photoelectric component and the magnet assembly in any of the above embodiments, and the magnet assembly is fixedly connected to the photoelectric component.

[0049] For the lamp sticker of the embodiment of the present invention, since the magnet assembly in the above embodiment is adopted, the eccentric problem of multiple magnet assemblies in the sleeve can be avoided, thereby improving the assembly efficiency of the lamp sticker.

[0050] In some embodiments, one end of the fixing post 1 away from the magnet block 2 is provided with a limiting flange 15 extending in a direction away from the central axis of the fixing post 1, and the photoelectric component is provided with a mounting hole (not shown in the figure) adapted to the fixing post 1; the second end of the fixing post 1 extends into the mounting hole, and the limiting flange 15 abuts against the photoelectric component. Exemplarily, the aperture of the mounting hole is slightly smaller than the diameter of the fixing post 1, and the fixing post 1 is fixed to the photoelectric component by interference fit, and the limiting flange is used to prevent the magnet assembly from falling off the photoelectric component.

[0051] On the other hand, the embodiment of the present invention also provides a ceiling lamp, which includes the above lamp sticker.

[0052] The ceiling lamp provided by the embodiment of the present invention can improve the assembly speed of the ceiling lamp because the lamp sticker in the above embodiment is adopted.

[0053] In the description of this specification, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0054] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope described in the claims.
