Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to an elastic fixing component, a lamp provided with the elastic fixing component, and a lighting system provided with the lamp. Background Art

[0002] Existing economical lamps have high cost requirements for the lamp body. Therefore, in order to control costs, the wall thickness of the lamp body is usually made relatively thin. However, due to the wall thickness limitation of the lamp body, it is impossible to use bolts to fix the lamp body and the light source board. Currently, the following methods are used to connect the lamp body and the light source board: gluing, rivets, riveting, and slot connection. Among them, the gluing connection method is cumbersome to operate, and has high requirements for the colloid and the uniformity of the gluing. In addition, the colloid is easily aged by the heat of the light source board, causing the light source board and the lamp body to fall off; the connection method of rivets and rivets requires the use of professional equipment such as rivet machines or rivet machines to operate, and after the light source board and the lamp body are connected using this connection method, it is difficult or even impossible to disassemble, so it is not conducive to the subsequent maintenance and replacement of the light source board; and the connection method of the slot connection is convenient for disassembly and assembly of the light source board and the lamp body, but the assembly requirements of this connection method are high. When the cumulative assembly tolerance is large, the light source board cannot be close to the lamp body or the heat dissipation carrier, resulting in the light source board unable to be timely cooled, thereby shortening the service life of the light source board, and when the cumulative assembly tolerance is small, it is not conducive to the assembly between the light source board and the lamp body, that is, the light source board is difficult to be inserted into the slot on the lamp body, and the light source board is very easy to deform during the assembly process, which makes the circuit on the light source board easily damaged and fail. Summary of the Invention

[0003] In order to solve the above problems, the main purpose of the present invention is to provide an elastic fixing assembly that is easy to assemble and disassemble and can ensure the tightness and firmness of the connection.

[0004] Another object of the present invention is to provide a lamp equipped with the elastic fixing assembly.

[0005] Another object of the present invention is to provide a lighting system equipped with the above-mentioned lamp.

[0006] In order to achieve the main purpose of the present invention, the present invention provides an elastic fixing assembly, which includes a clip and an elastic member. The clip has a supporting portion and a plug-in portion. The plug-in portion extends from the supporting portion. The plug-in portion has an elastically deformable hook portion near its own protruding end. The elastic member is sleeved on the plug-in portion. The first end of the elastic member can abut against the supporting portion, and a clamping position is formed between the second end of the elastic member and the hook portion.

[0007] As can be seen from the above, when the elastic fixing component fixes the fixed component, the plug-in part is passed through the fixed component, so that the hook part and the elastic part on the plug-in part are located on opposite sides of the fixed component and the elastic part is compressed, so that the elastic part pushes the support part to control the clamping part to move back to the fixed component under the action of its own elastic force, and at the same time the hook part moves toward the fixed component and abuts against the fixed component. At this time, a clamping position is formed between the elastic part and the hook part to clamp and fix the fixed component, and due to the action of the elastic part, the reliability of the elastic fixing component clamping and fixing the fixed component is ensured.

[0008] A further solution is that the plug-in portion includes two or more elastic arms distributed along the circumference of the support portion, and the extended ends of the elastic arms are curled into an arc shape toward the middle of the plug-in portion; the hook portion is located on the side of the elastic arm facing away from the middle of the plug-in portion.

[0009] As can be seen from the above, this design is conducive to improving the strength of the elastic arm, preventing the elastic arm from breaking due to elastic deformation, while also avoiding excessive deformation of the elastic arm and ensuring the elastic deformation effect of the elastic arm.

[0010] A preferred solution is that the hook portion has an inclined section and a bent section, the inclined section extends from the elastic arm back to the middle of the plug-in portion and obliquely toward the support portion, the bent section extends from the protruding end of the inclined section toward the support portion, the bent section is bent relative to the inclined section, and a clamping position is formed between the protruding end of the bent section and the second end of the elastic member.

[0011] As can be seen from the above, through the design of the hook portion, the hook portion itself can have a certain elastic deformation ability, which is beneficial to improving the clamping and fixing effect of the elastic fixing component on the fixed component, and at the same time is also beneficial to the molding of the hook portion to a certain extent.

[0012] Another preferred solution is that the support portion has a flat plate and a surrounding plate, the elastic arm extends from the flat plate, the first end of the elastic member can abut against the flat plate, the surrounding plate is arranged around the flat plate, and the surrounding plate is located between the flat plate and the hook portion.

[0013] As can be seen from the above, the setting of the enclosure is conducive to improving the strength of the flat plate, thereby ensuring the overall strength of the support part, avoiding excessive deformation of the support part due to the elastic force of the elastic part, and thus ensuring the clamping and fixing effect of the elastic fixing component on the fixed component; in addition, the above design is also conducive to improving the aesthetics of the product equipped with this elastic fixing component, and can better prevent external dust from entering the interior of the product.

[0014] A further solution is that the clip is formed by a stamping process; or the clip is formed by an injection molding process.

[0015] As can be seen from the above, using the stamping process to make the clip connector can make the production of the clip connector more convenient and help reduce production costs; while using the injection molding process to make the clip connector can help reduce the weight of the clip connector and help further improve the production efficiency of the clip connector.

[0016] A further solution is that when the clip is formed by a stamping process, the flat plate and the enclosure are provided with a first notch at the elastic arm, the elastic arm is stamped from the first notch, the elastic arm is provided with a second notch at the hook portion, and the hook portion is formed from the second notch.

[0017] As can be seen from the above, setting the first notch makes the stamping of the elastic arm more convenient and easy to operate; similarly, setting the second notch makes the stamping of the hook part more convenient and easy to operate, and makes the structure of the clip more simplified and reasonable.

[0018] Another preferred solution is that there are two elastic arms, and the two elastic arms are arranged in mirror symmetry; the angle between the two elastic arms is greater than 0° and less than or equal to 15°, and the first distance between the two elastic arms close to one end of the support part is greater than the second distance between the protruding ends of the two elastic arms.

[0019] As can be seen from the above, setting a certain angle between the two elastic arms is conducive to the elastic arms passing through the fixed component, making the installation of the elastic fixing component more convenient and easy to operate.

[0020] A further solution is that the elastic member is a compression spring; or the elastic member is a hollow elastic column, and the hollow elastic column is made of rubber, silicone or polyurethane.

[0021] As can be seen from the above, the use of compression springs as elastic parts is conducive to ensuring the clamping and fixing stability of the elastic fixing assembly, while also making the cost of the elastic fixing assembly lower; and as an alternative, a hollow elastic column made of rubber, silicone or polyurethane can also be used as the elastic part.

[0022] In order to achieve another purpose of the utility model, the utility model provides a lamp, including a lamp body and a light source board, the wall of the lamp body is provided with a first through hole, the light source board is installed in the lamp body, and the substrate of the light source board is provided with a second through hole that cooperates with the first through hole, wherein the lamp also includes the above-mentioned elastic fixing component, the plug-in part passes through the first through hole and the second through hole, one of the hook part and the elastic part is located inside the lamp body, and the other is located outside the lamp body, and the clamping position clamps and fixes the lamp body and the substrate.

[0023] As can be seen from the above, when the elastic fixing component is aligned with the lamp body and the light source board, the plug-in part is passed through the first through hole of the lamp body and the second through hole of the light source board, so that the hook part of the plug-in part and the elastic part are located on the opposite sides of the wall of the lamp body and the light source board and the elastic part is compressed, so that the elastic part pushes the support part to control the clamping part to move back toward the lamp body (or light source board) under the action of its own elastic force, and at the same time, the hook part moves toward the light source board (or lamp body) and abuts against the light source board (or lamp body). At this time, a clamping position is formed between the elastic part and the hook part to clamp and fix the lamp body and the light source board, and due to the action of the elastic part, the reliability of the elastic fixing component clamping and fixing the lamp body and the light source board is ensured, and the reliability of the lamp body dissipating heat to the light source board is ensured.

[0032] Elastic fixing component embodiment

[0033] Reference Figure 1 and Figure 2 The elastic fixing assembly 100 includes a clamping member 1 and an elastic member 2 .

[0034] Combine Figure 3 , the clip 1 has a support portion 11 and a plug-in portion. In the present embodiment, the plug-in portion preferably includes more than two elastic arms 12, and the more than two elastic arms 12 are distributed along the circumference of the support portion 11. Preferably, the number of elastic arms 12 is two, and the two elastic arms 12 are symmetrically arranged. The elastic arm 12 extends from the support portion 11, and the elastic arm 12 has an elastically deformable barb portion 121 near its own protruding end. In the present embodiment, the barb portion 121 is located on the side of the elastic arm 12 facing away from the middle of the plug-in portion, that is, the barb portion 121 is located on the side of the elastic arm 12 facing away from the other elastic arm 12; however, it should be noted that, as another optional solution, in other embodiments, the barb portion 121 may also be located on the side of the elastic arm 12 facing the other elastic arm 12, so that a structure similar to a card slot is formed between the barb portions 121 of the two elastic arms 12. Furthermore, the elastic arms 12 tend to move away from each other, and a spacing W is preferably provided between the two elastic arms 12, allowing the two elastic arms 12 to move toward or away from each other. The elastic member 2 is sleeved over the two elastic arms 12, with the first end of the elastic member 2 abutting the support portion 11 and the second end of the elastic member 2 forming a clamping point 10 with the barbed portions 121 of the two elastic arms 12.

[0035] The support portion 11 preferably has a flat plate 111 and a panel 112. The elastic arm 12 extends from the flat plate 111, and the first end of the elastic member 2 can abut against the flat plate 111. The panel 112 is arranged around the flat plate 111 in the circumferential direction, and the panel 112 is located between the flat plate 111 and the barb portion 121. The provision of the panel 112 is conducive to improving the strength of the flat plate 111, so as to ensure the overall strength of the support portion 11, and to prevent the support portion 11 from being excessively deformed by the elastic force of the elastic member 2, thereby ensuring the clamping and fixing effect of the elastic fixing component 100 on the fixed component. In addition, the design of the support portion 11 is conducive to improving the aesthetics of the product provided with the elastic fixing component 100. At the same time, the design of the support portion 11 can also prevent external dust from entering the interior of the product to a certain extent.

[0036] The barb portion 121 preferably includes an inclined section 1211 and a bent section 1212. The inclined section 1211 preferably extends from the middle portion of the elastic arm 12, facing away from the plug-in portion, and obliquely toward the support portion 11. That is, in this embodiment, the inclined section 1211 extends from the elastic arm 12, facing away from the other elastic arm 12, obliquely toward the support portion 11. The bent section 1212 extends from the protruding end of the inclined section 1211 toward the support portion 11, and the bent section 1212 is bent relative to the inclined section 1211. The protruding end 122 of the bent section 1212 forms a clamping position 10 with the second end of the elastic member 2. Preferably, the bent section 1212 is parallel to the height direction of the clip 1. By designing the barb portion 121 as described above, the barb portion 121 can have a certain elastic deformation ability under the cooperation of the inclined section 1211, the bent section 1212 and the manufacturing material, which is beneficial to improving the clamping and fixing effect of the elastic fixing component 100 on the fixed component. In addition, the above design is also beneficial to the molding of the barb portion 121 to a certain extent.

[0037] Furthermore, the extended end of the elastic arm 12 is curled into an arc shape toward the middle of the plug-in portion. In this embodiment, the extended end 122 of the elastic arm 12 is curled into an arc shape toward the other elastic arm 12. This design is conducive to improving the strength of the elastic arm 12, preventing the elastic arm 12 from breaking due to elastic deformation, and also avoiding excessive deformation of the elastic arm 12, and is conducive to ensuring the elastic deformation effect of the elastic arm 12. However, it should be noted that when the barb portion 121 is formed on the surface of the elastic arm 12 facing the other elastic arm 12, the extended end 122 of the elastic arm 12 is usually not designed to be curled into an arc shape, so as to ensure that the barb portions 121 of the two elastic arms 12 can cooperate with the elastic member 2 to clamp and fix the fixed component.

[0038] In addition, in this embodiment, the clip 1 is formed by a stamping process, and the material of the clip 1 is preferably stainless steel to ensure the structural strength of the clip 1 itself and the corrosion resistance of the clip 1. The use of stainless steel and the support of the clip 1 by a stamping process can make the production of the clip 1 more convenient and help reduce production costs. Preferably, based on the fact that the clip 1 is formed by a stamping process, the flat plate 111 and the enclosure 112 are provided with a first notch 113 at the elastic arm 12, and the elastic arm 12 is stamped and formed from the first notch 113. The provision of the first notch 113 can make the stamping of the elastic arm 12 more convenient and easy to operate; the elastic arm 12 is provided with a second notch 123 at the barb portion 121, and the barb portion 121 is formed from the second notch 123. Similarly, the provision of the second notch 123 makes the stamping of the barb portion 121 more convenient and easy to operate, and makes the structure of the clip 1 more simplified and reasonable. It should be noted that, in other embodiments, the clip 1 can also be molded by the injection molding process. Using the injection molding process to produce the clip 1 is beneficial to reducing the weight of the clip 1 and is beneficial to further improving the production efficiency of the clip 1. However, when using the injection molding process to mold the clip 1, a special injection mold needs to be made, which will increase the production cost to a certain extent.

[0039] like Figure 2 As shown, the two elastic arms 12 are preferably arranged in mirror symmetry, and there is preferably a non-zero angle a between the two elastic arms 12, which is greater than 0° and less than or equal to 15°; preferably, the angle a is 10°; wherein the first distance between the two elastic arms 12 near one end of the support portion 11 is greater than the second distance between the protruding ends of the two elastic arms 12. By arranging the two elastic arms 12 at a certain angle, it is convenient for the elastic arms 12 to pass through the fixed component, making the installation of the elastic fixing component 100 more convenient and easier to operate; and the angle design of the angle a can minimize the volume of the elastic fixing component 100 under the wall that makes the installation of the elastic fixing component 100 more convenient and easier to operate, thereby facilitating the miniaturization design of the product equipped with the elastic fixing component 100 and improving the aesthetics of the product.

[0040] In this embodiment, the elastic member 2 adopts a compression spring to ensure the clamping and fixing stability of the elastic fixing component 100, while also making the cost of the elastic fixing component 100 lower; and as another optional solution, in other embodiments, the elastic member 2 can also be a hollow elastic column, and the hollow elastic column can preferably be made of rubber, silicone or polyurethane.

[0041] In summary, it can be seen that through the design of the elastic fixing component 100, when the elastic fixing component 100 fixes the fixed component, the elastic arm 12 passes through the fixed component, so that the hook portion 121 of the elastic arm 12 and the elastic member 2 are located on opposite sides of the fixed component and the elastic member 2 is compressed. Under the action of its own elastic force, the elastic member 2 pushes the support portion 11 to control the clamping member 1 to move back toward the fixed component, and at the same time, the hook portion 121 moves toward the fixed component and abuts against the fixed component. At this time, a clamping position 10 is formed between the elastic member 2 and the hook portion 121 to clamp and fix the fixed component (one of the specific usage scenarios of the elastic fixing component 100 can be found in the use of the elastic fixing component 100 in the following lamp embodiment); in addition, due to the action of the elastic member 2, the reliability of the elastic fixing component 100 clamping and fixing the fixed component is ensured.

[0042] It should be noted that in other embodiments, as another optional scheme, the plug-in portion is no longer provided to include more than two elastic arms, but is in the shape of a truncated cone, and the bottom (i.e., the large diameter end) of the truncated cone-shaped plug-in portion is connected to the flat plate of the support portion, and the barb portion is provided close to the top (and the small diameter end) of the truncated cone-shaped plug-in portion; wherein, the shape of the barb portion is preferably basically the same as the shape when the plug-in portion includes more than two elastic arms, so it will not be repeated here.

[0043] Lamp Example

[0044] See also Figure 4 and Figure 5 The lamp 3 includes a lamp body 31, a light source board 32, and the elastic fixing assembly 100 described in the above-mentioned elastic fixing assembly embodiment. This embodiment is described by taking the elastic fixing assembly 100 as an example in which the plug-in portion includes an elastic arm; wherein, the wall of the lamp body 31 is provided with a first through hole 311, the light source board 32 is installed in the lamp body 31, and the base plate of the light source board 32 is provided with a second through hole 321 that matches the first through hole 311. The elastic fixing assembly 100 is used to fix the lamp body 31 and the light source board 32. When the elastic fixing assembly 100 is used to fix the lamp body 31 and the light source board 32, the elastic arm 12 is passed through the first through hole 311 and the second through hole 321, so that one of the barb portion 121 and the elastic member 2 is located inside the lamp body 31 and the other is located outside the lamp body 31, thereby allowing the clamping position 10 formed between the barb portion 121 and the elastic member 2 to clamp and fix the lamp body 31 and the base plate of the light source board 32.

[0045] As in the present embodiment, when the lamp body 31 and the light source board 32 are fixedly connected, the two elastic arms 12 of the clamping member 1 are passed through the first through hole 311 and the second through hole 321 in sequence from the outside of the lamp body 31 until the barb portion 121 on the elastic arm 12 moves to the bottom of the substrate of the light source board 32. At this time, the elastic member 2 is compressed by the lamp body 31 and the supporting portion 11 of the clamping member 1; in the process of the elastic arm 12 passing through the first through hole 311 and the second through hole 321, the two elastic arms 12 will move toward each other. When the barb portion 121 moves to the bottom of the light source board 32, the two elastic arms 12 will move away from each other under the action of their own elasticity, thereby causing the two barb portions 121 to also move away from each other and be in an open state. Next, release the pressure on the elastic fixing component 100, so that the elastic member 2 cooperates with the lamp body 31 to move the elastic arm 12 toward the outside of the lamp body 31 under the action of its own elastic force (that is, the hook portion 121 moves toward the substrate of the light source board 32), until the hook portion 121 abuts against the light source board 32. At this time, the clamping position 10 formed between the hook portion 121 and the elastic member 2 reliably clamps and fixes the lamp body 31 and the substrate of the light source board 32, so that the substrate of the light source board 32 can be close to the lamp body 31, and the lamp body 31 can reliably dissipate heat to the light source board 32.

[0046] Compared to the existing method of fixing the lamp body 31 and the light source board 32 with glue, the elastic fixing assembly 100 is simpler and more convenient to use to fix the lamp body 31 and the light source board 32. Furthermore, the light source board 32 will not fall off the lamp body 31 due to the heat of the light source board 32, thereby ensuring the stability and reliability of the fixed connection between the lamp body 31 and the light source board 32. Compared to the existing fixing methods using rivets or rivets, the lamp body 31 and the light source board 32 fixed by the elastic fixing assembly 100 are removable and easy to disassemble, thereby facilitating the repair and replacement of the light source board 32. Compared to the existing method of fixing the lamp body 31 and the light source board 32 with a slot structure, the elastic fixing assembly 100, through the cooperation between the clip 1 and the elastic member 2, effectively solves the problem of accumulated tolerance when fixing the lamp body 31 and the light source board 32 with a slot structure. It also makes the assembly and disassembly of the lamp body 31 and the light source board 32 more convenient, and the connection is more secure and stable.

[0047] Lighting system embodiment

[0048] A lighting system includes a control terminal and the lamp described in the above-mentioned lamp embodiment. The lamp also includes a control unit, the control unit being electrically connected to the substrate of the light source board. The control terminal is electrically connected to the control unit of the lamp, and / or the control terminal and the control unit exchange information. The control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel, or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the control unit. When the control terminal is an intelligent control panel or remote control, the control unit is provided with a first wireless communication module and the control terminal is provided with a second wireless communication module. The control terminal is electrically connected to the control unit, and / or the first wireless communication module and the second wireless communication module exchange information. Alternatively, the control terminal can be a smart mobile terminal (such as a mobile phone, tablet computer, smart wearable device, etc.) or an artificial intelligence robot. By providing the above-mentioned lamp, the lighting system makes maintenance and replacement of the light source board more convenient and easy to operate, and helps ensure the reliability of heat dissipation from the lamp body to the light source board, thereby ensuring the service life of the light source board.

[0049] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
