Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) lighting, in particular to an arm lamp for a UAV and a tethered UAV. Background Art

[0002] Traditional lighting fixtures are mounted on top of a lighting bracket to achieve top-down illumination. With the rapid development of electronic information technology, drone technology has also developed rapidly. Many existing drones can be equipped with lighting fixtures and fly into the air for lighting operations. However, the lighting fixtures used in existing drones have a complex structure, making them difficult to assemble and produce. In addition, they have poor heat dissipation performance and a short service life, which seriously affects the user's efficiency and experience. Utility Model Content

[0003] The main purpose of the present invention is to overcome the defects of the above-mentioned background technology and provide an arm light and a tethered drone.

[0004] In order to achieve the above-mentioned purpose, the present invention proposes an arm lamp for a drone, comprising a lamp housing, a plurality of light components, a heat sink and a connector. The bottom end face of the lamp housing is provided with a base plate, and the top end face of the lamp housing is provided with a positioning substrate. The base plate, the lamp housing and the positioning substrate together enclose an installation cavity. A plurality of light components are installed in the installation cavity and are electrically connected to the positioning substrate. The base plate is provided with light holes corresponding to the number of light components. The positioning substrate is bonded and connected to the heat sink on a side away from the lamp housing, and the connector is provided above the heat sink. The installation cavity is enclosed by the base plate, the lamp housing and the positioning substrate. Multiple groups of light components are installed in the installation cavity and are electrically connected to the positioning substrate at the same time. Multiple groups of light components can be made conductive without wires, which simplifies the structure while reducing the difficulty of assembly and production. The waste heat generated by the light components can be discharged in a timely manner through the heat sink bonded to the other side of the positioning substrate, effectively extending the service life of the light components.

[0005] Further optimizing the technical solution, the lighting assembly includes a lamp bead, a split substrate, and a focusing cup. The lamp bead is mounted on the split substrate and electrically connected to the positioning substrate. A lamp bead gasket is provided around the lamp bead, and the light input end of the focusing cup abuts the lamp bead gasket, while the light output end of the focusing cup corresponds to the light hole. The split substrate and the positioning substrate are separately connected for power supply, facilitating subsequent replacement and maintenance. If one set of lighting assemblies is damaged, only the corresponding set needs to be replaced. The lamp bead gasket provides stable support and protection for the lamp bead, preventing short circuits caused by contact between the focusing cup and the lamp bead or its solder joints, and allowing the lamp bead to remain centered, improving the lighting effect.

[0006] To further optimize the technical solution, a lens is provided on the upper cover of the light-emitting end of the focusing cup to protect the lamp beads and extend their service life.

[0007] To further optimize the technical solution, a sealing ring is provided on the lens, which can further enhance the dustproof and waterproof effect.

[0008] A further optimized technical solution is to provide a stepped surface on the inner wall of the light hole, wherein the lens is embedded in the light hole and the sealing ring is pressed against the stepped surface. By sandwiching the lens between the stepped surface and the light-emitting end of the focusing cup, and providing a sealing ring in between, the sealing effect is improved while the light-emitting end of the focusing cup is kept as close to the outside of the light hole as possible, thus avoiding light obstruction and illumination impairment.

[0009] To further optimize the technical solution, the connector includes a tube-clamping aluminum column, a fixing plate, and a C-shaped clip. Several sets of mounting ears extend symmetrically on both sides of the positioning base. One end of the tube-clamping aluminum column is vertically fixed to the mounting ears. The two ends of the fixing plate are respectively fixedly connected to the other end of the tube-clamping aluminum column. The C-shaped clip is fixed to the fixing plate. The C-shaped clip facilitates the entire arm light to be hung on the drone's arm for use.

[0010] To further optimize the technical solution, the lamp housing is a rectangular frame structure with a plurality of reinforcing ribs provided on the lamp housing, which makes the lamp housing structure more stable and has a longer service life.

[0011] A further optimized technical solution comprises a plurality of mounting holes and positioning posts provided on the lamp housing, and fixing holes and positioning holes corresponding to the mounting holes and positioning posts respectively provided on the base plate and positioning substrate. Fastening screws are provided in the fixing holes and mounting holes for securing the lamp. The coordination of the positioning posts and positioning holes facilitates quick alignment of the mounting holes and fixing holes after the base plate and positioning substrate are mounted on the lamp housing, and the fastening screws are then used to secure the lamp together, further improving assembly efficiency.

[0012] To further optimize the technical solution, an electrical connector is provided on the outer wall of the lamp housing, and the electrical connector is electrically connected to the positioning substrate, so as to facilitate quick connection with the power supply cable for power supply.

[0013] The present invention also proposes a tethered drone, comprising a drone body, a power supply, a power supply cable and the above-mentioned arm light, wherein the arm light is installed on the arm of the drone body through a connector, one end of the power supply cable is electrically connected to the power supply, and the other end of the power supply cable is electrically connected to the electrical connector on the arm light and the drone body, respectively. By hanging the arm light on the arm of the drone body and carrying it to the control, the power supply is supplied to the drone body and the arm light at the same time through the power supply cable, so that the drone body can carry the arm light and hover in the air for a long time to perform lighting operations, effectively improving the lighting effect.

[0014] The beneficial effects of the present invention include: a mounting cavity is formed by the base plate, the lamp housing and the positioning substrate, and multiple groups of lighting components are installed in the mounting cavity and electrically connected to the positioning substrate, and multiple groups of lighting components can be electrically connected to the positioning substrate at the same time without the need for wires, which simplifies the structure and reduces the difficulty of assembly and production. In addition, by fitting the positioning substrate and the heat sink for heat dissipation, the waste heat generated by the lighting components can be discharged in time, effectively extending the service life of the lighting components and improving the user's usage efficiency and experience.

[0027] See also Figures 1 to 6In one embodiment, the arm lamp 1 disclosed includes a lamp housing 101, a plurality of light components 102, a heat sink 103 and a connector 104. The lamp housing 101 is formed by integral injection molding and has a long rectangular frame structure. A plurality of reinforcing ribs 1011 are provided on the side walls of the lamp housing 101 to enhance the stability of its structure. A bottom plate 105 is provided on the bottom end surface of the lamp housing 101, and a positioning substrate 106 is provided on the top surface of the lamp housing 101. The bottom plate 105 is sealed at the bottom end of the lamp housing 101, and the positioning substrate 106 is sealed at the top end of the lamp housing 101. The bottom plate 105, the lamp housing 101 and the positioning substrate 106 together enclose an installation cavity 107. The plurality of light components 102 are installed in the installation cavity 107 and are fixed to the fixed cavity 107. The positioning substrate 106 is electrically connected. Specifically, a light on-state electrode 1062 is provided on the positioning substrate 106, and the power-on end of the light component 102 is fitted with the light on-state electrode 1062 for conductive connection. In this embodiment, the light components 102 are set to 6 groups; light holes 1051 corresponding to the number of light components 102 are opened on the bottom plate 105, and the light emitted by the light component 102 passes through the light holes 1051. The side of the positioning substrate 106 away from the lamp housing 101 is fitted and connected to the heat sink 103. Specifically, the positioning substrate 106 adopts an aluminum substrate, and the heat sink 103 adopts a multi-tooth aluminum heat sink. The connector 104 is arranged above the heat sink 103 for connecting to the arm of the drone. In this embodiment, the base plate 105, the lamp housing 101 and the positioning substrate 106 are used to enclose an installation cavity 107, and multiple groups of lighting components 102 are installed in the installation cavity 107 and electrically connected to the positioning substrate 106. No wires are required to achieve electrical connection between multiple groups of lighting components 102 and the positioning substrate 106 at the same time, which simplifies the structure and reduces the difficulty of assembly and production. In addition, the heat sink 103 attached to the other side of the positioning substrate 106 can discharge the waste heat generated by the lighting component 102 during operation in a timely manner, effectively extending the service life of the lighting component 102 and improving the user's usage efficiency and experience.

[0028] In a specific example, the lighting assembly 102 includes a lamp bead 1021, a split substrate 1022 and a focusing cup 1023. The lamp bead 1021 is mounted on the split substrate 1022 and is electrically connected to the positioning substrate 106. A lamp bead gasket 1024 is provided around the lamp bead 1021. The light input end of the focusing cup 1023 abuts against the lamp bead gasket 1024. The light output end of the focusing cup 1023 corresponds to the light hole 1051. Specifically, the lamp bead 1021 is an LED lamp bead, and the focusing cup 1023 is an aluminum light cup. It is fixed on an independent split substrate 1022 by welding, and then powered on by connecting the light-on potential 1062 on the split substrate 1022 with the positioning substrate 106, which is convenient for subsequent replacement and maintenance; the lamp bead gasket 1024 provides stable support and protection for the lamp bead 1021, avoiding short circuit caused by contact between the aluminum focusing cup 1023 and the lamp bead 1021 or its solder joint, and allowing the lamp bead 1021 to be centered, so that the light spot emitted by the focusing cup 1023 is good, effectively improving the lighting effect.

[0029] In a preferred embodiment, a lens 1025 is provided on the light-emitting end of the focusing cup 1023. The lens 1025 is preferably transparent, but can also be other colored lenses as needed to emit light of different colors. The lens also prevents foreign matter and rain from entering the focusing cup 1023, which could affect the lifespan of the lamp beads 1021, and provides a certain degree of dust and water resistance.

[0030] In a preferred embodiment, a sealing ring 1026 is provided on the lens 1025. The provision of the sealing ring 1026 further improves the dustproof and waterproof effects.

[0031] In a specific example, a stepped surface 1052 is provided on the inner wall of the light hole 1051. The lens 1025 is embedded in the light hole 1051, and the sealing ring 1026 is pressed against the stepped surface 1052. By sandwiching the lens 1025 between the stepped surface 1052 and the light-emitting end of the focusing cup 1023, with the sealing ring 1026 disposed in between, dust, rain, and the like are prevented from entering the mounting cavity 107, further improving the dust and water resistance. Furthermore, the light-emitting end of the focusing cup 1023 is positioned as close as possible to the outside of the light hole 1051, preventing light from being blocked by the sidewalls of the light hole 1051.

[0032] In a preferred embodiment, the connector 104 includes a tube-clamping aluminum column 1041, a fixing plate 1042, and a C-shaped clip 1043. Several sets of mounting ears 1061 extend symmetrically on both sides of the positioning base plate 106. One end of the tube-clamping aluminum column 1041 is vertically fixed to the mounting ear 1061. The two ends of the fixing plate 1042 are fixedly connected to the other ends of the tube-clamping aluminum column 1041 on both sides, and the C-shaped clip 1043 is fixedly mounted to the fixing plate 1042. Specifically, each arm lamp 1 is provided with two sets of connectors 104. The C-shaped clip 1043 on the connector 104 has a certain degree of elastic deformation, which allows it to be quickly clamped to the arm 201 to suspend the entire arm lamp 1 on the arm 201. The length of the tube-clamping aluminum column 1041 is greater than the thickness of the heat sink 103, which keeps the fixing plate 1042 away from the heat sink 103 to prevent it from pressing on the tooth surface of the heat sink 103 and affecting heat dissipation.

[0033] In a specific example, a number of mounting holes 1012 and positioning columns 1013 are respectively provided on the lamp housing 101, and fixing holes 1010 and positioning holes 109 corresponding to the mounting holes 1012 and the positioning columns 1013 are respectively opened on the base plate 105 and the positioning substrate 106. Fastening screws for fixing are provided in the fixing holes 1010 and the mounting holes 1012 (not shown in the figure). The positioning columns 1013 and the positioning holes 109 cooperate to facilitate the installation of the base plate 105 and the positioning substrate 106 at both ends of the lamp housing 101, so that the mounting holes 1012 and the fixing holes 1010 can be aligned, and then fixed by fastening screws, which further facilitates assembly.

[0034] In a specific example, an electrical connector 108 is provided on the outer wall of the lamp housing 101, and the electrical connector 108 is electrically connected to the positioning substrate 106. Specifically, a connector cover 1014 is provided at one end of the lamp housing 101, and the electrical connector 108 is inserted into the connector cover 1014 for fixation. The model of the electrical connector 108 is XT30U-M, and the electrical connector 108 is conveniently connected to the power supply 3 through the electrical connector 108.

[0035] See also Figures 1 to 7 In one embodiment, a tethered drone is also disclosed. The tethered drone includes a drone body 2, a power supply 3, a power supply cable 4, and the above-mentioned arm light 1. The arm light 1 is installed on the arm 201 of the drone body 2 through a connector 104. One end of the power supply cable 4 is electrically connected to the power supply 3, and the other end of the power supply cable 4 is electrically connected to the electrical connector 108 on the arm light 1 and the drone body 2, respectively, for connecting and supplying power to the drone body 2, the arm light 1, and the power supply 3, so that the drone body 2 can carry the arm light 1 into the air and stay for a long time to perform lighting work, thereby improving the lighting range.
