Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, in particular to a spliced ​​LED light source module. Background Art

[0002] A light source module is an integrated module that integrates LED lights, PCB boards, and waterproof casings on a heat dissipation backplane. Existing light source modules are generally installed using connecting ears formed at both ends of the backplane to connect to the connecting sockets on the parts to be installed. However, when additional light source modules are required, the installation of the light source modules becomes more troublesome due to the limited number of connecting sockets. Therefore, a new type of light source module is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the description and other drawings.

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a spliced ​​LED light source module.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a spliced ​​LED light source module, comprising a module body and a back panel, the module body being fixedly connected to the back panel, the back panel being provided with a through slot, a connector 1 and a connector 2 being slidably connected in the through slot, the two connectors being respectively located at the two exits of the through slot, a connecting mechanism 1 being provided on both the connector 1 and the connector 2, the back panel being provided with an elastic mechanism for keeping the connector 1 and the connector 2 in the through slot, the back panel being provided with a driving mechanism for enabling the connector 1 and the connector 2 to overcome the elastic force of the elastic mechanism and extend out of the through slot, and a connecting mechanism 2 being provided on both sides of the back panel.

[0006] By adopting the above technical solution, using the connector one and the connector two that can be received in the through groove by the elastic mechanism, when multiple light source modules need to be installed, the connector one and the connector two can be pushed out of the through groove by the driving mechanism, and the connecting mechanism on the connector one is connected with the connecting mechanism on the connector two on the adjacent light source module, so that the light source modules in the Y direction can be spliced, and the connecting mechanism two located on both sides of the back panel are used for splicing the light source modules in the X direction. At the same time, the connecting mechanism two also serves as the connecting part of the light source module and is connected to the base for installation of the lamp when not splicing. In this way, the light source module can be spliced ​​while reducing the increase in its own volume, so that multiple light source modules can be fixedly installed by splicing themselves in the absence of a connecting base.

[0007] Preferably, the connecting mechanism 1 includes a connecting ear 1, the connecting ear 1 being rotatably connected to the connecting member 1 or the connecting member 2, the connecting ear 1 being provided with a bolt hole, the connecting member 1 and the connecting member 2 both being provided with a splicing interface, the connecting ear 1 and the splicing interface on the connecting member 1 being centrally symmetrical with the connecting ear 1 and the splicing interface on the connecting member 2. The utility model utilizes the rotatable connecting ear 1 so that the connecting ear 1 can be rotated to a vertical state to be spliced ​​with the connecting ear 1 on the adjacent connecting member 2, and then a bolt is passed through the bolt holes on the two connecting ears 1, and a nut is screwed on to achieve fixation between the connecting member 1 and the connecting member 2. The splicing interface provided in a centrally symmetrical manner enables the connecting member 1 and the connecting member 2 on adjacent light source modules to be spliced ​​with each other, providing conditions for splicing between the two connecting ears 1.

[0008] Preferably, both the first and second connectors are provided with limiting grooves, and the first connecting ear is rotatably connected within the limiting grooves. The utility model utilizes the limiting grooves to limit the rotation range of the first connecting ear, so that it can only rotate between a vertical state and a horizontal state, thereby facilitating the storage of the first and second connectors and the connection between the first connecting ear.

[0009] Preferably, the elastic mechanism includes an elastic ring and two connecting hooks, the two connecting hooks being fixedly connected to the first connector and the second connector respectively, and the elastic ring being hooked onto the two connecting hooks respectively. The utility model utilizes the elastic force of the elastic ring to stretch the elastic ring when the first connector and the second connector move away from each other, thereby generating an elastic force. When the driving mechanism no longer acts on the first connector and the second connector, the first connector and the second connector are retracted into the through slot under the action of the elastic force of the elastic ring.

[0010] Preferably, the driving mechanism includes a rotating shaft and two pushing members, both of which are fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the back plate. The two pushing members abut against the first connector and the second connector, respectively. The rotating shaft is provided with a fixing mechanism for fixing the rotating shaft. When the rotating shaft is rotated, the two pushing members push the first connector and the second connector to slide in opposite directions, so that they can slide out of the two openings of the through slot respectively. The rotating shaft can be fixed by the fixing mechanism, so that the pushing members remain in the current position, so that the first connector and the second connector will not retract into the through slot under the action of the elastic ring.

[0011] Preferably, the fixing mechanism includes a sliding member, an elastic member, and a clamping column. The sliding member is slidably connected to the rotating shaft. The elastic member is disposed between the rotating shaft and the sliding member. The clamping column is fixedly connected to the sliding member. The back plate is provided with a clamping hole for the clamping column to be clamped in. The utility model utilizes the elastic force of the elastic member to keep the clamping column inserted into the clamping hole, thereby fixing the rotating shaft. When the fixation needs to be released, the sliding member is pulled in a direction to overcome the elastic force of the elastic member, so that the clamping column exits the clamping hole, thereby releasing the limit on the rotating shaft.

[0012] Preferably, the pushing member is arc-shaped, and the round edge of the pushing member abuts against the connecting member 1 or the connecting member 2. The utility model uses the arc-shaped pushing member to push the connecting member 1 and the connecting member 2, which can reduce the contact area and reduce the resistance.

[0013] Preferably, the second connecting mechanism includes two second connecting ears, each of which is provided with a bolt hole. The two second connecting ears are rotatably connected to the two ends of the back plate, and the back plate is fixedly connected to a limit plate for limiting the rotation range of the second connecting ears. The second connecting ear of the utility model can rotate and can be used normally as a connecting part of the light source module when in a horizontal state. When in a vertical state, it can be fitted with the second connecting ears on other light source modules and fixed by bolts and nuts to achieve horizontal splicing.

[0014] Preferably, the second connecting ear includes a connecting frame and a slide plate, the bolt hole is provided on the slide plate, the slide plate is slidably connected to the connecting frame, and the connecting frame is rotatably connected to the back plate. The utility model utilizes the sliding connection between the slide plate and the connecting member so that when the second connecting ear is in a vertical state, the portion with the bolt hole can move downward so that it is not blocked by the heat dissipation fins on the back plate, thereby facilitating the fixation between the second connecting ear.

[0015] In summary, the beneficial effects of the present invention are:

[0016] 1. By using the first and second connecting ears, the light source modules can be spliced ​​horizontally or vertically, and the light source modules can also be fixed when the number of connecting sockets on the installation part is insufficient.

[0017] 2. The connecting ear 1 can be stored together with the connecting piece 1 and the connecting piece 2 as well as the driving mechanism and the elastic mechanism, thereby reducing the space occupied when the splicing is not in use. The connecting ear 2 can serve as the connecting part during splicing and the connecting part during normal installation.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0030] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, removable connections, or integration; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or interaction between two components. However, the term "direct connection" indicates that the two connected entities are not connected through a transitional structure, but are connected solely through a connecting structure to form a single entity. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0033] like Figure 1-3 As shown, a spliced ​​LED light source module includes a module body 1 and a back panel 2. The module body 1 is fixedly connected to the back panel 2. The back panel 2 is provided with a through slot 3. A connector 1 4 and a connector 2 are slidably connected in the through slot 3. The two connectors are respectively located at the two exits of the through slot 3. Connecting mechanism 1 is provided on connecting member 1 4 and connecting member 2. The back panel 2 is provided with an elastic mechanism for keeping connecting member 1 4 and connecting member 2 in the through slot 3. The back panel 2 is provided with a driving mechanism for making connecting member 1 4 and connecting member 2 overcome the elastic force of the elastic mechanism and extend out of the through slot 3. Connecting mechanism 2 is provided on both sides of the back panel 2.

[0034] By adopting the above technical solution, using connector 1 4 and connector 2 that can be accommodated in the through groove 3 through an elastic mechanism, when multiple light source modules need to be installed, connector 1 4 and connector 2 can be pushed out of the through groove 3 through a driving mechanism, and the connecting mechanism on connector 1 4 is connected with the connecting mechanism on connector 2 on the adjacent light source module to achieve splicing between the light source modules in the Y direction, and the connecting mechanism 2 located on both sides of the back panel 2 is used for splicing of the light source modules in the X direction. At the same time, the connecting mechanism 2 also serves as the connecting part of the light source module and is connected to the base for installation of the lamp when not splicing. In this way, the light source module can be spliced ​​while reducing the increase in its own volume, so that multiple light source modules can be fixedly installed by splicing themselves in the absence of a connecting base.

[0035] Connecting mechanism 1 includes connecting ear 1 6, which is rotatably connected to connecting member 1 4 or connecting member 2. Connecting ear 1 6 is provided with a bolt hole 7, and both connecting member 1 4 and connecting member 2 are provided with a splicing interface 8. The connecting ear 1 6 and splicing interface 8 on connecting member 1 4 are centrally symmetrically arranged with the connecting ear 1 6 and splicing interface 8 on connecting member 2. By rotating connecting ear 1 6, connecting ear 1 6 can be rotated to a vertical position for splicing with the connecting ear 1 6 on the adjacent connecting member 2. Bolts are then inserted through the bolt holes 7 on the two connecting ears 1 6, and nuts are tightened to secure the connecting member 1 4 and the connecting member 2. The centrally symmetrical splicing interface 8 allows connecting members 1 4 and 2 on adjacent light source modules to be spliced ​​together, providing conditions for splicing two connecting ears 1 6.

[0036] Both connector 1 4 and connector 2 are provided with limiting slots 9, and connecting ear 1 6 is rotatably connected in the limiting slots 9. The limiting slots 9 can limit the rotation range of connecting ear 1 6, so that it can only rotate between a vertical state and a horizontal state, which facilitates the storage of connector 1 4 and connector 2 and the connection between connecting ears 1 6.

[0037] The elastic mechanism includes an elastic ring 10 and two connecting hooks 11. The two connecting hooks 11 are fixedly connected to connector 1 4 and connector 2, respectively, and the elastic ring 10 is hooked onto the two connecting hooks 11. When connector 1 4 and connector 2 are moved away from each other by the elastic force of the elastic ring 10, the elastic ring 10 is stretched, generating an elastic force. When the driving mechanism no longer acts on connector 1 4 and connector 2, connector 1 4 and connector 2 are retracted into the through slot 3 under the elastic force of the elastic ring 10.

[0038] The drive mechanism includes a rotating shaft 12 and two pushers 13. Both pushers 13 are fixedly connected to the rotating shaft 12. The rotating shaft 12 is rotatably connected to the back plate 2. The two pushers 13 abut against the connecting member 1 4 and the connecting member 2, respectively. The rotating shaft 12 is provided with a fixing mechanism for fixing the rotating shaft 12. When the rotating shaft 12 is rotated, the two pushers 13 push the connecting member 1 4 and the connecting member 2 to slide in opposite directions, allowing them to slide out of the two openings of the through slot 3 respectively. The fixing mechanism can fix the rotating shaft 12, so that the pushers 13 remain in their current position, thereby preventing the connecting member 1 4 and the connecting member 2 from retracting into the through slot 3 under the action of the elastic ring 10.

[0039] The securing mechanism includes a sliding member 14, an elastic member 15, and a latch 16. The sliding member 14 is slidably connected to the rotating shaft 12. The elastic member 15 is disposed between the rotating shaft 12 and the sliding member 14. The latch 16 is fixedly connected to the sliding member 14. The back panel 2 defines a latch hole 17 for the latch 16 to engage. The elastic force of the elastic member 15 keeps the latch 16 inserted into the latch hole 17, thereby securing the rotating shaft 12. To release the securing mechanism, the sliding member 14 is pulled in a direction that overcomes the elastic force of the elastic member 15, causing the latch 16 to exit the latch hole 17, thereby releasing the restraint on the rotating shaft 12.

[0040] The pusher 13 is arc-shaped, and the round edge of the pusher 13 abuts against the connector 1 4 or the connector 2. Using the arc-shaped pusher 13 to push the connector 1 4 and the connector 2 can reduce the contact area and reduce the resistance.

[0041] The second connection mechanism includes two second connection ears 18, each of which has a bolt hole 7. The two second connection ears 18 are rotatably connected to the two ends of the back plate 2. The back plate 2 is fixedly connected to a limit plate 19 for limiting the rotation range of the second connection ears 18. The second connection ears 18 can rotate. When in a horizontal position, they can be used normally as the connection part of the light source module. When in a vertical position, they can be abutted with the second connection ears 18 on other light source modules and fixed with bolts and nuts to achieve horizontal splicing.

[0042] The second connecting lug 18 comprises a connecting frame 20 and a slide plate 21. Bolt holes 7 are defined in slide plate 21. Slide plate 21 is slidably connected to the connecting frame 20, and the connecting frame 20 is pivotally connected to the back plate 2. The sliding connection between slide plate 21 and the connector allows the portion of the second connecting lug 18 with the bolt holes 7 to move downward when the latter is in a vertical position, freeing it from obstruction by the heat dissipation fins on the back plate 2. This facilitates the securement of the second connecting lug 18.

[0043] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
