Tunnel lamp driving control device and tunnel lamp

Abstract

This utility model discloses a tunnel light drive control device and a tunnel light. The tunnel light drive control device includes a housing, a battery, and a driver. The driver controls the tunnel light fixture, and the battery provides power. The battery and driver are located inside the housing. The top surface of either the battery or the driver is in close contact with the inner top surface of the housing, and the bottom surface of the other is in close contact with the inner bottom surface of the housing, with a gap between the battery and the driver. Each battery and driver has a corresponding fixing component for securing it to the housing. Because the battery and driver are in close contact with the inner surface of the housing, forming a large area of ​​direct contact, the large amount of heat generated by the battery and driver can be directly transferred to the housing, and then dissipated to the outside air by the housing, resulting in good heat dissipation. Moreover, the gap between the battery and the driver not only facilitates individual heat dissipation but also reduces mutual interference between them.

Description

To address this issue, energy storage batteries are installed as emergency power sources, and a driver is configured to enable intelligent switching between mains power and battery power. However, the internal space of tunnel light fixtures is limited, and the batteries and drivers, due to their large size, cannot be directly integrated into the fixture; therefore, they must be installed independently in an external enclosure. However, the batteries and drivers generate a significant amount of heat during operation, and prolonged exposure to high temperatures significantly impacts their lifespan. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Example 1 See Figures 1 to 7 This embodiment provides a tunnel light drive control device, including a housing 1, a battery 2, and a driver 3. The driver 3 is used to control the tunnel light fixture, and the battery 2 is used to power the driver 3 and the tunnel light fixture. The battery 2 and the driver 3 are located inside the housing 1. The top surface of either the battery 2 or the driver 3 is in close contact with the inner top surface of the housing 1, and the bottom surface of the other is in close contact with the inner bottom surface of the housing 1, with a gap between the battery 2 and the driver 3. The battery 2 and the driver 3 are respectively equipped with corresponding fasteners for fixing the battery 2 / driver 3 to the housing 1.

[0025] Because battery 2 and driver 3 are respectively attached to the inner surface of housing 1, forming a large area of ​​direct contact with housing 1, the large amount of heat generated by battery 2 and driver 3 can be directly transferred to housing 1 through contact, and then the housing 1 dissipates heat to the outside air, resulting in good heat dissipation. Moreover, the gap between battery 2 and driver 3 not only facilitates heat dissipation for each of them, but also reduces mutual interference between them.

[0026] The tunnel light drive control device of this embodiment will be further described below.

[0027] The housing 1 includes a shell 4, a front cover plate 5, and a rear cover plate. The front and rear ends of the shell 4 are open, and the front and rear cover plates 5 and 5 are respectively connected to the shell 4 and close the openings at both ends of the shell 4. The top surface and the inner surface of the housing 1 are both located on the shell 4. The shell 4 and the front and rear cover plates 5 can be connected by screws or clips, etc., which is not limited here.

[0028] The two fasteners are the upper fastener 6 and the lower fastener 15. The upper fastener 6 is used to press the battery 2 / driver 3 against the top surface inside the housing 1, and the lower fastener 15 is used to install the driver 3 / battery 2 onto the bottom surface inside the housing 1.

[0029] The upper fixing member 6 includes a first limiting part and the bottom surface of the battery 2 / driver 3 which is in close contact with the top surface inside the housing 1, thereby cooperating with the top surface inside the housing 1 to limit the vertical position of the battery 2 / driver 3.

[0030] Preferably, an elastic pad 14 can be provided between the first limiting part and the bottom surface of the battery 2 / driver 3 that is in close contact with the top surface of the housing 1. The two opposing surfaces of the elastic pad 14 are in close contact with the first limiting part and the bottom surface of the battery 2 / driver 3 that is in close contact with the top surface of the housing 1, respectively. The elastic pad 14 can, on the one hand, use its own elasticity to cooperate with the first limiting part to press the corresponding battery 2 / driver 3 firmly against the top surface of the housing 1. On the other hand, the friction between the elastic pad 14 and the battery 2 / driver 3 it is in close contact with can prevent the battery 2 / driver 3 from moving easily in the left-right and front-back directions. In this embodiment, the elastic pad 14 is made of sponge, but in other embodiments, the elastic pad 14 can also be made of rubber or other materials. This utility model does not limit this.

[0031] The lower fixing member 15 includes a second limiting part, which is arranged circumferentially around the driver 3 / battery 2 that is closely attached to the bottom surface of the inner side of the housing 1 and abuts against multiple side walls of the driver 3 / battery 2, thereby limiting the displacement of the driver 3 / battery 2 in the left-right and front-back directions.

[0032] In this embodiment, the top surface of battery 2 is in close contact with the inner top surface of housing 1, and the bottom surface of driver 3 is in close contact with the inner bottom surface of housing 1. The specific structures of the upper fixing member 6 and the lower fixing member 15 will be described below using this as an example. Of course, in other embodiments, the top surface of driver 3 can also be in close contact with the inner top surface of housing 1, and the bottom surface of battery 2 can be in close contact with the inner bottom surface of housing 1. In this case, due to the difference in structure between battery 2 and driver 3, the upper fixing member 6 and the lower fixing member 15 can also be adapted to better match the corresponding battery 2 / driver 3.

[0033] The first limiting part of the upper fixing member 6 is a bearing plate 7. An elastic pad 14 is provided between the upper surface of the bearing plate 7 and the bottom surface of the battery 2. The upper surface of the elastic pad 14 is in close contact with the bottom surface of the battery 2, and the lower surface of the elastic pad 14 is in close contact with the upper surface of the bearing plate 7. Moreover, the bearing plate 7 is provided with heat dissipation holes 8 to facilitate heat dissipation.

[0034] The upper fixing member 6 also includes two first limiting plates 9 and two second limiting plates 10. The two first limiting plates 9 are located on the left and right sides of the battery 2, corresponding to the left and right side walls of the battery 2 respectively; the two first limiting plates 9 cooperate to limit the left-right position of the battery 2. The two second limiting plates 10 are located on the front and rear sides of the battery 2, corresponding to the front and rear side walls of the battery 2 respectively; the two second limiting plates 10 cooperate to limit the front-rear position of the battery 2. Specifically, the first limiting plate 9 may be in close contact with the corresponding left / right side wall of the battery 2, or the minimum distance between the first limiting plate 9 and the corresponding left / right side wall of the battery 2 may be less than or equal to 1 cm; the second limiting plate 10 may be in close contact with the corresponding front / rear side wall of the battery 2, or the minimum distance between the second limiting plate 10 and the corresponding front / rear side wall of the battery 2 may be less than or equal to 1 cm. The bottoms of both the first limiting plates 9 and the second limiting plates 10 are connected to the supporting plate 7. The first limiting plate 9 and the second limiting plate 10 can restrict the displacement of the battery 2 in the left-right and front-back directions (since the battery 2 is pressed against the top surface inside the housing 1 by the supporting plate 7, only a rough restriction is needed on the left-right and front-back positions of the battery 2). Furthermore, in this embodiment, the first limiting plate 9, the second limiting plate 10, and the supporting plate 7 can be a single plate, with the first limiting plate 9 and the second limiting plate 10 formed by bending portions of the plate relative to the supporting plate 7.

[0035] The upper fixing part also includes two connecting plates 11, which are respectively connected to two first limiting plates 9. The connecting plates 11 are located on the side of the first limiting plates 9 connected to them that is away from the battery 2. Preferably, the connecting plates 11 are parallel to the inner top surface of the box body 1. Specifically, in this embodiment, the connecting plates 11 and the first limiting plates 9 are also the same plate, and the connecting plates 11 are formed by bending a portion of the plate relative to the first limiting plates 9. A plurality of connecting posts 12 are provided on the inner top surface of the box body 1. The lower end of the connecting post 12 abuts against the top surface of the connecting plate 11. The connecting post 12 is provided with screws, which pass through the top surface of the box body 1, the connecting post 12 and the connecting plate 11, thereby realizing the connection between the connecting plate 11 and the top surface of the box body 1.

[0036] A supporting protrusion 13 corresponding to the connecting plate 11 is provided on the inner side wall of the housing 1. The side wall portion of the supporting protrusion 13 is connected to the inner side wall of the housing 1, and the bottom surface of the supporting plate 7 abuts against the top of the corresponding side wall portion of the supporting protrusion 13. The supporting protrusion 13 provides support for the connecting plate 11, sharing the weight of the battery 2 and the upper fixing member 6 at the connection points of the connecting plate 11, the connecting post 12, and the screws. On the other hand, it can limit the connecting plate 11 when it is fixed to the connecting post 12 with screws, preventing it from moving up and down, thus facilitating the installation of screws. Moreover, the supporting protrusion 13 is arranged in the front-to-back direction. When the front cover plate 5 and the rear cover plate are installed and fixed to the housing 4 with screws, the screws can be connected to the supporting protrusion 13 after passing through the front cover plate 5 / rear cover plate. That is, the supporting protrusion 13 can also serve to fix the front cover plate 5 / rear cover plate.

[0037] The connection between the connecting plate 11 and the housing 1 allows the upper fixing member 6 to be fixed to the housing 1, thereby enabling the battery 2 to be pressed and fixed to the top surface inside the housing 1 by the bearing plate 7 in the upper fixing member 6. Preferably, the entire upper fixing member 6 can be made as a single piece.

[0038] The second limiting portion in the lower fixing member 15 includes two third limiting plates 16 and two fourth limiting plates 17. The two third limiting plates 16 are located on the left and right sides of the driver 3, respectively, and correspond to the left and right side walls of the driver 3; the third limiting plates 16 abut against the left / right side wall of the corresponding battery 2. The two fourth limiting plates 17 are located on the front and rear sides of the driver 3, respectively, and correspond to the front and rear side walls of the driver 3; the fourth limiting plates 17 abut against the front / rear side walls of the corresponding driver 3. The front and rear ends of the third limiting plates 16 are connected to the two fourth limiting plates 17, thereby connecting the two third limiting plates 16 and the two fourth limiting plates 17 into a single unit. Preferably, the third limiting plates 16 are perpendicular to the left / right side walls of the driver 3, and the fourth limiting plates 17 are parallel to the front / rear side walls of the driver 3.

[0039] The bottom surface inside the housing 1 is provided with several connecting posts, the upper end of which abuts against the bottom surface of the third limiting plate 16; the connecting posts are provided with screws, which pass through the bottom surface of the housing 1, the connecting posts and the third limiting plate 16, thereby realizing the connection between the third limiting plate 16 and the bottom surface of the housing 1.

[0040] The lower fixing member 15 also includes two upper limit plates 19, which are respectively connected to two fourth limiting plates 17. Specifically, in this embodiment, the upper limit plate 19 and the fourth limiting plate 17 can be the same plate, and the upper limit plate 19 is formed by bending a portion of the plate relative to the fourth limiting plate 17. The bottom surface of the upper limit plate 19 is in close contact with the top surface of the driver 3, or the minimum distance between the bottom surface of the upper limit plate 19 and the top surface of the driver 3 is less than 1 cm. The cooperation between the upper limit plate 19 and the bottom surface inside the housing 1 can limit the displacement of the driver 3 in the vertical direction (since the driver 3 is placed on the bottom surface inside the housing 1, it is not necessary to strictly require the upper limit plate 19 to press the driver 3 tightly against the bottom surface inside the housing 1; it is only necessary to roughly limit the vertical position of the driver 3).

[0041] An mounting protrusion 18 corresponding to the third limiting plate 16 is provided on the inner side wall of the housing 1. The side wall portion of the mounting protrusion 18 is connected to the inner side wall of the housing 1, and the top surface of the third limiting plate 16 abuts against the bottom of the side wall portion of the mounting protrusion 18. The mounting protrusion 18 can limit the third limiting plate 16 when it is fixed to the connecting column with screws, preventing it from moving up and down, thus facilitating the installation of screws. Moreover, the mounting protrusion 18 is arranged in the front-to-back direction. When the front cover plate 5 and the rear cover plate are respectively fixed to the housing 4 with screws, the screws can be connected to the mounting protrusion 18 after passing through the front cover plate 5 / rear cover plate. That is, the mounting protrusion 18 can also serve to fix the front cover plate 5 / rear cover plate.

[0042] The lower fixing member 15 can be fixed to the housing 1 by connecting the third limiting plate 16 to the housing 1, thereby allowing the position of the driver 3 in the left-right and front-back directions to be limited by the third limiting plate 16 and the fourth limiting plate 17 in the lower fixing member 15. Preferably, the entire upper fixing member 6 can be made as a single piece.

[0043] Example 2 See Figure 8 This embodiment provides a tunnel light drive control device based on embodiment 1. In this embodiment, no connecting column 12 is provided on the top surface inside the housing 1, and the two connecting plates 11 on the upper fixing member 6 abut against the two bearing protrusions 13 on the inner side wall of the housing 1 to form a limiting position; and an elastic pad 14 is provided between the bottom of the battery 2 and the top surface of the bearing plate 7.

[0044] The connecting plate 11 is limited by the supporting protrusion 13, so that the upper fixing member 6 and the battery 2 fixed thereon are fixed in the vertical direction. Since the battery 2 and the supporting plate 7 are provided with an elastic pad 14, when the upper fixing member 6 is inserted with the battery on it (at this time, the connecting plate 11 in the upper fixing member 6 slides into the box 1 along the upper surface of the corresponding supporting protrusion 12), the elastic pad 12 is compressed. After the upper fixing member 6 and the battery are inserted into place, the restoring force of the elastic pad 14 forces the top surface of the battery 2 to be in close contact with the top surface of the box 1. In addition, the friction between the elastic pad 14, the battery 2 and the supporting plate 7 also prevents the battery 2 from easily moving relative to the supporting plate 7 in the horizontal direction.

[0045] Example 3 See Figure 1 This embodiment provides a tunnel light, including a lamp 20 and a tunnel light drive control device as described in Embodiment 1 or Embodiment 2. The lamp 20 is provided with brackets 21 on both sides, and the tunnel light drive control device is fixedly installed between the two side brackets 21. A gap is left between the tunnel light drive control device and the lamp 20 to avoid the heat generated by the tunnel light drive control device from affecting the lamp 20.
