Description

Technical Field

[0001] The present invention relates to the technical field of outdoor lighting devices, and more specifically, it relates to a multifunctional drive installation structure for outdoor lighting and its installation method. Background Art

[0002] Street lamps, as facilities that provide lighting functions for roads, mainly consist of lamps with light sources, lamp poles, electric wires, and foundation embedded parts, and these components form the lamp body part. Among them, the lamp is set at the top of the lamp pole, the lamp pole is set on the foundation embedded part, the foundation embedded part is set on the ground, the lamp pole adopts a hollow structure, the electric wire is placed inside the lamp pole and electrically connects the power part of the foundation embedded part with the light source. Under the action of the lamp, the light diffuses in all directions.

[0003] Currently, street lamps on the market include a lamp body and a drive part arranged on the lamp body. For traditional street lamps, the lamp body and the drive part are integrated. If the drive part is damaged, the entire lamp body needs to be disassembled, which makes replacement extremely inconvenient, time-consuming and laborious, and also increases labor costs. Therefore, there has emerged a structure on the market that separates the drive part from the lamp body. For example, the patent number is 202510041417.0, and the patent name is a street lamp driver separation, detachable installation structure and its detection method, which adopts a separated drive installation method. However, this installation method forms a circuit through an elastic member and an annular conductive disk. But in actual operation, such a connection method cannot effectively maintain a good assembly effect for a long time. Therefore, how to change the traditional connection method to form a double locking structure to ensure the long-term and effective maintenance of the external drive is the problem existing currently. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a multifunctional drive installation structure for outdoor lighting and its installation method, which has a double locking structure and a springback fastening structure, and can reduce the locking fatigue between the base and the bottom cover.

[0005] To achieve the above object, the present invention provides the following technical solution: An outdoor lighting multi-functional drive installation structure, including a lamp body and an external drive part detachably connected to the lamp body. The external drive part includes a base detachably connected to the lamp body, a bottom cover electrically connected to the base, and a housing body connected to the bottom cover. A drive circuit board is provided inside the housing body, and the drive circuit board is electrically connected to one end of an electrical connection plug provided on the bottom cover. The other end of the electrical connection plug on the bottom cover is electrically connected to an electrical connection socket provided on the bottom cover. A double locking structure is provided between the bottom cover and the base. The double locking structure includes an L-shaped inner installation groove provided on the inner wall of the bottom cover and an outer installation block provided on the outer wall of the base. The double locking member structure further includes an L-shaped structure provided on the electrical connection plug and a groove structure provided in the electrical connection socket and adapted to the L-shaped structure. When the bottom cover is connected to the base, the bottom cover is pressed and then rotated. At this time, the outer installation block enters the inner installation groove, and the L-shaped structure on the electrical connection plug enters the groove structure to complete the connection between the bottom cover and the base.

[0006] The present invention is further provided as follows: A rebound fastening structure is further provided between the base and the bottom cover. The rebound fastening structure includes a first air chamber provided in the bottom cover, an elastic abutting block provided in the first air chamber and slidably connected to the first air chamber, an air outlet provided on the first air chamber, a second air chamber communicated with the air outlet and provided outside the first air chamber, a reset device provided in the second air chamber, and a return flow channel provided on the elastic abutting block. The reset device is configured to discharge air unidirectionally outward when pressed. The air throughput of the return flow channel is greater than the air outlet volume of the reset device. When the bottom cover is rotationally matched with the base, the elastic abutting block is pressed, and the air flow in the first air chamber enters the second air chamber. The air pressure in the second air chamber increases, forming a pressure on the reset device. At this time, the reset device is pressed to discharge air unidirectionally outward to form pressure maintaining for the second air chamber, so that the elastic abutting block maintains the position of the last compression limit.

[0007] The present invention is further provided as follows: An annular sidewall airbag is further provided on the inner sidewall of the return flow channel. The sidewall airbag is configured to be concave inward when receiving the air flow back, so as to offset the returned air flow.

[0008] The present invention is further configured as follows: The reset device includes a reset air chamber connected to the second air chamber, a pressure-bearing piston plate disposed between the reset air chamber and the second air chamber, a reset spring disposed in the reset air chamber and abutting against the pressure-bearing piston plate, a one-way valve disposed in the reset air chamber, and an air inlet plug disposed in the reset air chamber. After the reset spring is compressed, the one-way valve provided in the reset air chamber can only discharge air unidirectionally. After being compressed and stabilized, a constant pressure is formed in the reset air chamber, and the reset spring always remains in a compressed state. When the bottom cover is unscrewed, the return flow channel on the elastic abutting block is opened. At this time, a passage is formed between the first air chamber and the second air chamber. By opening the air inlet plug, the reset air chamber is filled with air, and the reset of the reset spring is completed.

[0009] The present invention is further configured as follows: The drive circuit board is provided with an NFC module for adjusting the power of the lamp body through PWA programming; a light control module for adjusting the color temperature of the lamp according to the light intensity; an external adjustment module for externally connecting a regulator through a plug and adjusting the power within 0-10V; a thermistor for adjusting its own resistance according to the temperature change of the aluminum substrate of the lamp body, thereby adjusting the output current and adjusting the output power.

[0010] An installation method suitable for the above-mentioned outdoor lighting multi-functional drive installation structure specifically includes the following steps. S1: First, drive-connect the interface of the base with the connector in the lamp body, and then thread-connect the base with the drive installation port of the lamp body.

[0011] S2: After pairing the inner installation groove of the bottom cover with the outer installation block of the base, by pressing the bottom cover, the outer installation block is guided along the L-shaped groove structure of the inner installation groove.

[0012] When the bottom cover is slowly pressed, the elastic abutting block forms a pressure on the first air chamber. After the air flow in the first air chamber flows to the second air chamber, it forms a pressure on the pressure-bearing piston plate again. After the reset air chamber is pressed, the one-way valve discharges part of the gas in the reset air chamber to form pressure holding, and the installation of the bottom cover is completed.

[0013] When the bottom cover is quickly pressed, the elastic abutting block forms a pressure on the first air chamber. After the air flow in the first air chamber flows to the second air chamber, it forms a pressure on the pressure-bearing piston plate again. After the reset air chamber is pressed, the one-way valve has no time to discharge the gas, and the air flow flows back to the side wall air bag, thereby offsetting the force after the quick press, and still forming a slow installation of the bottom cover.

[0014] S3: After electrically connecting the circuit board in the outer shell body with the electrical connection plug, thread-connect it with the bottom cover to complete the installation of the external drive.

[0015] By adopting the above technical solutions, the beneficial effects are as follows: 1. In the present invention, the external drive part is set to include a base detachably connected to the lamp body, a bottom cover electrically connected to the base, and a housing connected to the bottom cover. A drive circuit board is provided in the housing, and the drive circuit board is electrically connected to one end of an electrical connection plug provided on the bottom cover. The other end of the electrical connection plug on the bottom cover is electrically connected to an electrical connection socket provided on the bottom cover, changing the traditional connection method of spring pins. The connection is made through the connection between the other end of the electrical connection plug and the electrical connection socket provided on the bottom cover, which makes the connection more stable. Moreover, in order to reduce the inconvenience of connection between the bottom cover and the base caused by screw connection, a double locking structure is provided between the bottom cover and the base. The setting of the double locking structure enables an internal and external two-way locking effect between the base and the bottom cover. The double locking structure is set to include an L-shaped inner installation groove provided on the inner wall of the bottom cover and an outer installation block provided on the outer wall of the base; the double locking structure further includes an L-shaped structure provided on the electrical connection plug and a groove structure provided in the electrical connection socket and adapted to the L-shaped structure. With the above structure, when the bottom cover is connected to the base, after the bottom cover is pressed and rotated, the outer installation block enters the inner installation groove at this time, and the L-shaped structure on the electrical connection plug enters the groove structure, completing the connection between the bottom cover and the base, thus forming a double locking effect, greatly improving the stability. Moreover, relying on a simple locking structure, the connection between the bottom cover and the base can be achieved;

[0016] 2. In order to ensure the stable connection of the double locking structure, reduce the damage to the double locking structure caused by improper operation, and improve the connection firmness between the base and the bottom cover, a spring-back fastening structure is further provided between the base and the bottom cover. The spring-back fastening structure is set to include a first air chamber provided in the bottom cover, an elastic abutting block provided in the first air chamber and slidably connected to the first air chamber, an air outlet provided on the first air chamber, a second air chamber communicated with the air outlet and provided outside the first air chamber, a reset device provided in the second air chamber, and a return flow channel provided on the elastic abutting block. The reset device is configured to discharge air unidirectionally when pressed. The ventilation volume of the return flow channel is greater than the air outlet volume of the reset device. Therefore, with the above structure, when the bottom cover is rotationally matched with the base, the elastic abutting block is pressed, the air flow in the first air chamber enters the second air chamber, the air pressure in the second air chamber increases, forming a pressure on the reset device. At this time, the reset device is pressed to discharge air unidirectionally, forming a pressure holding for the second air chamber, so that the elastic abutting block maintains the position of the last compression limit, thus reducing the damage to the double locking structure. Moreover, the spring-back fastening structure can also form a spring-back force between the base and the bottom cover, making the connection between the two more firm;

[0017] 3. When installing the bottom cover, if the force is unevenly controlled, especially when it is too large, the side wall airbag, which is annular and arranged on the inner side wall of the reflux channel, is configured to be concave inward under the pressure of the air flow reflux, so as to offset the reflux air flow. Since the air flow through the reflux channel is greater than the air output of the one-way valve in the reset air chamber, when the pressure on the bottom cover increases instantaneously, the air flow in this first air chamber will directly form pressure on the side wall airbag because it cannot enter the second air chamber in time, thus offsetting this part of the air flow and gradually offsetting the pressure. After the pressure is constant, the pressure on the side wall airbag decreases and it resets. The air flow in the first air chamber enters the second air chamber and forms pressure on the reset air chamber, thereby discharging the air pressure in the reset air chamber and maintaining the final constancy.

[0018] 4. In the present invention, an NFC module is also added to adjust the power of the lamp body through PWA programming; a light control module is used to adjust the color temperature of the lamp according to the light intensity; an external adjustment module is externally connected to a regulator through a plug and adjusts the power within 0 - 10V; a thermistor is used to adjust its own resistance according to the temperature change of the aluminum substrate of the lamp body, and then adjust the output current and the output power. Thus, the output power of the lamp body can be adaptively adjusted by NFC or external means, and the color temperature of the lamp can also be directly adjusted by the light control module. At the same time, through the thermistor, the resistance can be adjusted according to the temperature change of the aluminum substrate of the lamp body, and then the output current can be adjusted to adjust the output power, further improving the energy-saving effect of the outdoor lamp and greatly enhancing the practicality.

[0027] An outdoor lighting multi-functional drive installation structure, comprising a lamp body 1 and an external drive part 2 detachably connected to the lamp body 1. The external drive part 2 includes a base 20 detachably connected to the lamp body 1, a bottom cover 21 electrically connected to the base 20, and a housing 22 connected to the bottom cover 21. A drive circuit board is provided inside the housing 22, and the drive circuit board is electrically connected to one end of an electrical connection plug 210 provided on the bottom cover 21. The other end of the electrical connection plug 210 on the bottom cover 21 is electrically connected to an electrical connection socket 201 provided on the bottom cover 21. A double locking structure is provided between the bottom cover 21 and the base 20. The double locking structure includes an L-shaped inner installation groove 211 provided on the inner wall of the bottom cover 21 and an outer installation block 202 provided on the outer wall of the base 20. The double locking member structure further includes an L-shaped structure 212 provided on the electrical connection plug 210 and a groove structure provided in the electrical connection socket 201 and adapted to the L-shaped structure 212. When the bottom cover 21 is connected to the base 20, the bottom cover 21 is pressed and rotated. At this time, the outer installation block 202 enters the inner installation groove 211, and the L-shaped structure 212 on the electrical connection plug 210 enters the groove structure, completing the connection between the bottom cover 21 and the base 20. In the present invention, the external drive part 2 is set to include a base 20 detachably connected to the lamp body 1, a bottom cover 21 electrically connected to the base 20, and a housing 22 connected to the bottom cover 21. And a drive circuit board is provided inside the housing 22, and the drive circuit board is electrically connected to one end of an electrical connection plug 210 provided on the bottom cover 21. The other end of the electrical connection plug 210 on the bottom cover 21 is electrically connected to an electrical connection socket 201 provided on the bottom cover 21, changing the traditional connection method of spring pins. The connection is made through the connection method between the other end of the electrical connection plug 210 and the electrical connection socket 201 provided on the bottom cover 21. In this way, the connection is more stable. Moreover, in order to reduce the inconvenience of connection between the bottom cover 21 and the base 20 caused by threaded connection, a double locking structure is provided between the bottom cover 21 and the base 20. The setting of the double locking structure enables an internal and external two-way locking effect to be formed between the base 20 and the bottom cover 21. And the double locking structure is set to include an L-shaped inner installation groove 211 provided on the inner wall of the bottom cover 21 and an outer installation block 202 provided on the outer wall of the base 20. The double locking member structure further includes an L-shaped structure 212 provided on the electrical connection plug 210 and a groove structure provided in the electrical connection socket 201 and adapted to the L-shaped structure 212. With the above structure, when the bottom cover 21 is connected to the base 20, the bottom cover 21 is pressed and rotated. At this time, the outer installation block 202 enters the inner installation groove 211, and the L-shaped structure 212 on the electrical connection plug 210 enters the groove structure, completing the connection between the bottom cover 21 and the base 20, thus forming a double locking effect, greatly improving the stability, and relying on a simple locking structure, the connection between the bottom cover 21 and the base 20 can be achieved.

[0028] Further, a resilient fastening structure is also provided between the base 20 and the bottom cover 21. The resilient fastening structure includes a first air chamber 30 disposed within the bottom cover 21, an elastic abutting block 31 disposed within the first air chamber 30 and slidably connected to the first air chamber 30, an air outlet 32 disposed on the first air chamber 30, a second air chamber 33 communicated with the air outlet 32 and disposed outside the first air chamber 30, a reset device 4 disposed within the second air chamber 33, and a return flow channel 310 disposed on the elastic abutting block 31. The reset device 4 is configured to discharge air unidirectionally when pressed. The air throughput of the return flow channel 310 is greater than the air output of the reset device 4. When the bottom cover 21 is rotationally engaged with the base 20, the elastic abutting block 31 is pressed, and the air flow within the first air chamber 30 enters the second air chamber 33. The air pressure within the second air chamber 33 increases, forming a pressure on the reset device 4. At this time, the reset device 4 is pressed to discharge air unidirectionally, forming a pressure holding for the second air chamber 33, so that the elastic abutting block 31 maintains the position of the last compression limit. In order to ensure that the double-locking structure can be stably connected, and to reduce the damage to the double-locking structure caused by improper operation, and to improve the connection firmness between the base 20 and the bottom cover 21, a resilient fastening structure is also provided between the base 20 and the bottom cover 21, and the resilient fastening structure is set to include a first air chamber 30 disposed within the bottom cover 21, an elastic abutting block 31 disposed within the first air chamber 30 and slidably connected to the first air chamber 30, an air outlet 32 disposed on the first air chamber 30, a second air chamber 33 communicated with the air outlet 32 and disposed outside the first air chamber 30, a reset device 4 disposed within the second air chamber 33, and a return flow channel 310 disposed on the elastic abutting block 31. The reset device 4 is configured to discharge air unidirectionally when pressed. The air throughput of the return flow channel 310 is greater than the air output of the reset device 4. Therefore, with the above structure, when the bottom cover 21 is rotationally engaged with the base 20, the elastic abutting block 31 is pressed, and the air flow within the first air chamber 30 enters the second air chamber 33. The air pressure within the second air chamber 33 increases, forming a pressure on the reset device 4. At this time, the reset device 4 is pressed to discharge air unidirectionally, forming a pressure holding for the second air chamber 33, so that the elastic abutting block 31 maintains the position of the last compression limit, thereby reducing the damage to the double-locking structure, and the resilient fastening structure can also form a resilient force between the base 20 and the bottom cover 21, thereby making the connection between the two more firm.

[0029] Further, an annular sidewall airbag 311 is provided on the inner sidewall of the return flow channel 310. The sidewall airbag 311 is configured such that when affected by the air flow reflux, the sidewall airbag 311 is pressed and recessed inward to offset the reflux air flow. When installing the bottom cover 21, in case of uneven force control, especially when the force is too large, due to the annular sidewall airbag 311 provided on the inner sidewall of the return flow channel 310, the sidewall airbag 311 is configured such that when affected by the air flow reflux, the sidewall airbag 311 is pressed and recessed inward to offset the reflux air flow. Since the air flow through - put of the return flow channel 310 is greater than the air output of the one - way valve 43 in the reset air chamber 40, when the pressure on the bottom cover 21 increases instantaneously, the air flow in the first air chamber 30 will directly exert pressure on the sidewall airbag 311 because it cannot enter the second air chamber 33 in time, thus offsetting this part of the air flow and making the pressure gradually offset. After the pressure becomes constant, the pressure on the sidewall airbag 311 decreases and it resets. The air flow in the first air chamber 30 enters the second air chamber 33 and exerts pressure on the reset air chamber 40, thereby discharging the air pressure in the reset air chamber 40 and maintaining the final constancy.

[0030] Further, the reset device 4 includes a reset air chamber 40 connected to the second air chamber 33, a pressure - bearing piston plate 41 disposed between the reset air chamber 40 and the second air chamber 33, a reset spring 42 disposed in the reset air chamber 40 and abutted against the pressure - bearing piston plate 41, a one - way valve 43 disposed in the reset air chamber 40, and an air inlet plug 44 disposed in the reset air chamber 40. In the embodiment of the present invention, by configuring the reset device 4 to include the reset air chamber 40, the pressure - bearing piston plate 41, the reset spring 42, the one - way valve 43, and the air inlet plug 44, when the pressure - bearing piston plate 41 moves towards the reset spring 42 side, the reset spring 42 is compressed. The one - way valve 43 provided in the reset air chamber 40 can only discharge air unidirectionally. After the pressure is stabilized, a constant pressure is formed in the reset air chamber 40, and the reset spring 42 always remains in a compressed state. When the bottom cover 21 is unscrewed, the return flow channel 310 on the elastic abutting block 31 is opened. At this time, the first air chamber 30 and the second air chamber 33 form a passage. By opening the air inlet plug 44, the reset air chamber 40 is filled with air, and the reset spring 42 is reset. Then, when the user disassembles the bottom, the first air chamber 30 can be changed from the sealed state to the open state, and the air inlet plug 44 can also reset the reset spring 42, further completing the disassembly and the subsequent installation stability.

[0031] Furthermore, an NFC module is provided on the driving circuit board for adjusting the power of the lamp body 1 through PWA programming; a light control module for adjusting the color temperature of the lamp according to the light intensity; an external adjustment module for externally connecting a regulator through a plug and adjusting the power within 0 - 10V; a thermistor for adjusting its own resistance according to the temperature change of the aluminum substrate of the lamp body 1, thereby adjusting the output current and the output power. In the present invention, an NFC module is also added for adjusting the power of the lamp body 1 through PWA programming; a light control module for adjusting the color temperature of the lamp according to the light intensity; an external adjustment module for externally connecting a regulator through a plug and adjusting the power within 0 - 10V; a thermistor for adjusting its own resistance according to the temperature change of the aluminum substrate of the lamp body 1, thereby adjusting the output current and the output power. Then, the output power of the lamp body 1 can be adaptively adjusted in an NFC manner or an external manner, and the color temperature of the lamp can also be directly adjusted through the light control module. At the same time, through the thermistor, the resistance of the thermistor can be adjusted according to the temperature change of the aluminum substrate of the lamp body 1, thereby adjusting the output current and the output power, further improving the energy-saving effect of the outdoor lamp and greatly enhancing the practicability.

[0032] In the embodiment of the present invention, there are a total of 8 electrical connection plugs 210, which enclose the zero line, the live line, the positive and negative connection heads of the lamp body 1, the ground wire, the positive and negative poles for external power adjustment, and the NTC / 12V connection head. Users can connect the corresponding structures according to their needs. Of course, for the normal power-on circuit connection, the present invention will not elaborate.

[0033] An installation method suitable for the above-mentioned outdoor lighting multi-functional driving installation structure specifically includes the following steps. S1: First, drive-connect the interface of the base 20 with the connector inside the lamp body 1, and then thread-connect the base 20 with the driving installation port of the lamp body 1.

[0034] S2: After pairing the inner installation groove 211 of the bottom cover 21 and the outer installation block 202 of the base 20, by pressing the bottom cover 21, guide the outer installation block 202 along the L-shaped groove structure of the inner installation groove 211.

[0035] When the bottom cover 21 is slowly pressed, the elastic abutting block 31 forms a pressure on the first air chamber 30. The air flow in the first air chamber 30 flows to the second air chamber 33 and then forms a pressure on the pressure-bearing piston plate 41. After the reset air chamber 40 is pressurized, the one-way valve 43 discharges part of the gas in the reset air chamber 40 to form pressure holding, completing the installation of the bottom cover 21.

[0036] When the bottom cover 21 is quickly pressed, the elastic contact block 31 forms a pressure on the first air chamber 30. After the air flow in the first air chamber 30 flows to the second air chamber 33, it forms a pressure on the pressure-bearing piston plate 41. After the reset air chamber 40 is pressurized, the one-way valve 43 is too late to discharge the gas, and the air flow flows back to the side wall airbag 311, thereby canceling the force after the quick press, so as to still form a slow installation of the bottom cover 21.

[0037] S3. After the circuit board in the outer housing 22 is electrically connected to the electrical connection plug 210, it is then threadedly connected to the bottom cover 21 to complete the installation of the external drive.

[0038] By adopting the above technical solutions, the beneficial effects are as follows. In the assembly method of the present invention, after the inner installation groove 211 and the outer installation block 202 of the base 20 are paired, by pressing the bottom cover 21, the outer installation block 202 is guided along the L-shaped groove structure of the inner installation groove 211, and then through the spring-back fastening structure, the adjustment of different air pressure changes in the force condition is carried out, so that when the bottom cover 21 is installed, a constant pressure can be maintained, thereby reducing the damage to the double locking structure and affecting the connection stability.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solutions of the present invention should be included in the protection scope of the present invention.
