Description

Technical Field

[0001] The present invention relates to the technical field related to lighting equipment, and in particular to a street lamp module and a street lamp and a system including the street lamp module. Background Art

[0002] Street lights are an important part of urban infrastructure. In recent years, with the development of technology, the upgrading and transformation of street lights have played an important role in improving the quality, safety and intelligence of urban lighting. Nowadays, smart street lights, as part of urban intelligent construction, integrate a variety of intelligent functions.

[0003] As the functions of street lamps are improved, the number of related components loaded inside their shells is gradually increasing. Since street lamps are exposed to the outside world, over time, some failures will inevitably occur in the internal power supply components. At this time, the back cover of the shell needs to be removed to facilitate the staff to inspect and repair the internal components.

[0004] When performing the above construction, the workers need to remove the back cover. The existing street lamp back cover is usually connected to the street lamp housing through screws. Therefore, the entire removal process is more complicated, which increases the operation time. Due to the high-altitude operation, the operation risk is also increased. Summary of the invention

[0010] A cover body, which is arranged on a side of the shell away from the surface cover, is connected to the shell through an elastic locking mechanism, and is used to close the hysteresis cavity and the two side cavities, wherein the elastic locking mechanism cooperates with a pull-out unlocking mechanism arranged in the side cavity, and the pull-out unlocking mechanism is also connected to a top cover mechanism;

[0011] When the pull-out unlocking mechanism moves, it can cause the elastic locking mechanism and the top cover mechanism to move in sequence, the elastic locking mechanism releases the locking state between the cover body and the shell, and the top cover mechanism performs an ejection action on the unlocked cover body.

[0012] As a further solution of the present invention: a plurality of protrusions are formed on the cover body, and the protrusions are integrally formed with the cover body. When the cover body and the shell are in a locked state, the protrusions are located in the side cavity and cooperate with the elastic locking mechanism.

[0013] As a further solution of the present invention: a first inclined surface is formed at one end of the protrusion away from the cover body, the first inclined surface is connected to the side of the protrusion, and a limiting groove cooperating with the elastic locking mechanism is provided on the side of the protrusion.

[0014] As a further solution of the present invention: the elastic locking mechanism includes two locking members movably arranged in the side cavity, the two locking members are respectively connected to two groups of elastic telescopic members arranged in the side cavity, and a connecting shaft is fixedly connected between the two locking members, the connecting shaft cooperates with the pull-out unlocking mechanism, and the locking member is formed with a connected second inclined surface and a limiting surface on one side of the protruding portion.

[0015] As a further solution of the present invention: the elastic telescopic part includes a mounting tube fixedly installed in the side cavity, a support rod slidably fitted with the mounting tube, and a first cylindrical spring arranged inside the mounting tube, the head end of the support rod is fixed to the locking part, and the tail end is connected to the first cylindrical spring, and the end of the first cylindrical spring away from the support rod is connected to the inner wall of the mounting tube.

[0016] As a further solution of the present invention: the pull-out unlocking mechanism includes a connecting plate movably arranged in the side cavity and two driving members fixed on the connecting plate, the driving members are arranged in a hook shape and cooperate with the connecting shaft, and the connecting plate is connected to the top cover mechanism and is also connected to an elastic pull-out member.

[0017] As a further solution of the present invention: the elastic drawer comprises a guide cylinder fixed in the side cavity and a pull rod fixed to the connecting plate, the pull rod is slidably fitted with the guide cylinder and penetrates to the outside of the housing;

[0018] The pull rod is also fixed to a convex ring slidably arranged inside the guide cylinder. A second cylindrical spring is arranged inside the guide cylinder and sleeved on the outer circumference of the pull rod. One end of the second cylindrical spring is connected to the convex ring, and the other end is connected to the inner wall of the guide cylinder.

[0019] As a further solution of the present invention: the top cover mechanism includes a cross bar fixedly mounted on the connecting plate, a frame-shaped portion formed at one end of the cross bar away from the connecting plate, and a top rod slidably arranged in the frame-shaped portion, and a column is fixedly arranged at one end of the top rod away from the cover body;

[0020] Among them, a motion guide plate is also fixed in the side cavity, and a slide groove adapted to the column is provided on the motion guide plate. The column passes through the slide groove and is slidably connected to the motion guide plate. The slide groove includes a connected straight through groove and an inclined through groove.

[0022] A street lamp system, comprising the street lamp.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] By arranging a plurality of protrusions on the cover body, and movably arranging a locking piece cooperating with the protrusions in the side cavity, in actual use, it is only necessary to push the cover body into the hysteresis cavity with force, and by utilizing the cooperation between the first inclined surface and the second inclined surface, the locking piece moves and produces elastic deformation during the pushing-in process of the cover body; and after the protrusion on the cover body and the locking piece are fully engaged, the locking piece and the protrusion are elastically reset to achieve the purpose of fully combining the two, and the protrusion and the locking piece restrict each other, so as to realize the detachable connection between the cover body and the shell, and at the same time have the effect of convenient assembly;

[0025] Accordingly, when the cover needs to be disassembled, including replacement of parts and related maintenance work, the maintenance personnel do not need to rely on tools (such as common threaded connections require the use of screwdrivers, conventional snap connections require the use of prying tools, etc.), and only need to apply pulling force to the pull-out unlocking mechanism to cause the locking piece to be separated from the protruding portion; when the locking piece and the protruding portion are separated, the mutual restriction between the two disappears, and the locking state of the cover and the shell is released, and the two can be disassembled without any resistance and effort. Since there is no resistance, it can effectively prevent the relevant restricted parts from being damaged during the disassembly process, and there is even a risk of breaking and complete damage;

[0026] In addition, after the locking piece is disengaged from the protrusion, the top cover mechanism is triggered by mechanical cooperation, and a thrust force toward the outside of the shell is applied to the cover body. Under the action of this thrust force, the cover body can be more smoothly disengaged from the shell, playing a role in assisting disassembly and preventing the cover body from being embedded in the shell and difficult to remove.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0040] See also Figure 1-Figure 10 In an embodiment of the present invention, a street lamp module includes a housing 1 and further includes:

[0041] A cover 28 is installed on one side of the housing 1, and a lighting component is provided in the cover 28, and the lighting component is electrically connected to a power supply component provided in the housing 1;

[0042] Partition plates 8, two of which are provided in the housing 1, the two partition plates 8 divide the interior of the housing 1 into a hysteresis chamber 9 and two side chambers 10 respectively located on both sides of the hysteresis chamber 9, and the power supply assembly is provided in the hysteresis chamber 9;

[0043] A cover body 5 is provided on a side of the housing 1 away from the surface cover 28, and is connected to the housing 1 through an elastic locking mechanism, and is used to close the hysteresis chamber 9 and the two side chambers 10, and the elastic locking mechanism cooperates with a pull-out unlocking mechanism provided in the side chamber 10, and the pull-out unlocking mechanism is also connected to a top cover mechanism;

[0044] When the pull-out unlocking mechanism moves, it can cause the elastic locking mechanism and the top cover mechanism to move in sequence, the elastic locking mechanism releases the locking state between the cover body 5 and the shell 1, and the top cover mechanism performs an ejection action on the unlocked cover body 5.

[0045] It should be additionally explained that the surface cover 28 is connected to the tempered glass 2 , and the lighting assembly includes an aluminum substrate 3 arranged in the surface cover 28 , a plurality of lenses 4 arranged on the aluminum substrate 3 , and a reflector 7 located between the aluminum substrate 3 and the tempered glass 2 .

[0046] In actual use, as the use time increases, the power supply component in the hysteresis chamber 9 is prone to failure. When a failure occurs, the staff needs to perform maintenance, and first of all, the cover body 5 needs to be removed;

[0047] Specifically, during operation, the pull-out unlocking mechanism is controlled to move so that the pull-out unlocking mechanism cooperates with the elastic locking mechanism. During this process, the pull-out unlocking mechanism will prompt the elastic locking mechanism and the top cover mechanism to move in sequence, and the elastic locking mechanism will release the locked state between the cover body 5 and the shell 1. Then, the top cover mechanism will apply a pushing force to the unlocked cover body 5, so that the cover body 5 is pushed out from the shell 1, and the removal of the cover body 5 is completed. Compared with the threaded connection between the cover body 5 and the shell 1, the present application uses the interlocking cooperation between the mechanical structures, so that the staff can quickly complete the removal of the cover body 5 without using removal tools. Therefore, it brings convenience to the work of maintenance workers. At the same time, since the staff usually need to work at heights during maintenance, reducing the use of tools can also effectively improve the safety of the operation.

[0048] Please refer again Figure 8 , Fig. 9 as well as Fig.10 , a plurality of protrusions 11 are formed on the cover body 5, and the protrusions 11 are integrally formed with the cover body 5. When the cover body 5 and the housing 1 are in a locked state, the protrusions 11 are located in the side cavity 10 and cooperate with the elastic locking mechanism. A first inclined surface 1101 is formed at one end of the protrusion 11 away from the cover body 5, and the first inclined surface 1101 is connected to the side of the protrusion 11, and a limiting groove 1102 that cooperates with the elastic locking mechanism is provided on the side of the protrusion 11.

[0049] When assembling the cover body 5, the staff aligns the cover body 5 with the retardation cavity 9, and the protrusion 11 with the side cavity 10, and then pushes the cover body 5 into the retardation cavity 9. Correspondingly, the protrusion 11 enters the side cavity 10, and the first inclined surface 1101 acts on the elastic locking mechanism to prompt the elastic locking mechanism to store elastic potential energy. Then, after the cover body 5 is pushed to the terminal, the limiting groove 1102 corresponds to the elastic locking mechanism. At this time, the elastic locking mechanism releases the stored elastic potential energy, and then the elastic locking mechanism enters the limiting groove 1102, so that the cover body 5 is restricted and locked;

[0050] When it is necessary to remove the cover body 5 to inspect and repair the power supply component in the hysteresis chamber 9, the pull-out unlocking mechanism is controlled to drive the elastic locking mechanism to be withdrawn from the limiting groove 1102. Then, the elastic locking mechanism releases the restriction on the protrusion 11 through the limiting groove 1102, and then the top cover mechanism can smoothly push the cover body 5 out of the shell 1.

[0051] The elastic locking mechanism includes two locking members 12 movably arranged in the side cavity 10, the two locking members 12 are respectively connected to two groups of elastic telescopic members arranged in the side cavity 10, and a connecting shaft 16 is fixedly connected between the two locking members 12, the connecting shaft 16 cooperates with the pull-out unlocking mechanism, and the locking member 12 is formed with a connected second inclined surface 1201 and a limiting surface 1202 on one side facing the protruding portion 11.

[0052] When the cover body 5 is pushed into the hysteresis chamber 9, the first inclined surface 1101 will be released from the second inclined surface 1201. As the cover body 5 is pushed in, the first inclined surface 1101 cooperates with the second inclined surface 1201, which will cause the locking member 12 to give way. Specifically, the locking member 12 moves in a direction away from the protruding portion 11, and allows the elastic telescopic member to store elastic potential energy. After the cover body 5 is pushed to the terminal, the locking member 12 corresponds to the limiting groove 1102. At this time, the elastic telescopic member releases the stored elastic potential energy and drives the locking member 12 to bounce into the limiting groove 1102, and the limiting surface 1202 fits with a side of the limiting groove 1102 close to the first inclined surface 1101.

[0053] The elastic telescopic member includes a mounting tube 14 fixedly installed in the side cavity 10, a support rod 15 slidably fitted with the mounting tube 14, and a first cylindrical spring 13 arranged inside the mounting tube 14, the head end of the support rod 15 is fixed to the locking member 12, and the tail end is connected to the first cylindrical spring 13, and the end of the first cylindrical spring 13 away from the support rod 15 is connected to the inner wall of the mounting tube 14.

[0054] Furthermore, when the first inclined surface 1101 cooperates with the second inclined surface 1201 to cause the locking member 12 to give way, the support rod 15 correspondingly contracts toward the inside of the mounting tube 14, and the first cylindrical spring 13 is compressed. After the cover body 5 is pushed to the terminal, the locking member 12 corresponds to the limiting groove 1102, and then the first cylindrical spring 13 rebounds, driving the support rod 15 to slide toward the outside of the mounting tube 14, and the locking member 12 is bounced into the limiting groove 1102, restricting the protrusion 11, so that the cover body 5 and the shell 1 are connected.

[0055] Please refer again Fig. 9 and Fig.10 The pull-out unlocking mechanism includes a connecting plate 18 movably arranged in the side cavity 10 and two driving members 17 fixed on the connecting plate 18. The driving member 17 is arranged in a hook shape and cooperates with the connecting shaft 16. The connecting plate 18 is connected to the top cover mechanism and is also connected to an elastic pull-out member. The elastic pull-out member includes a guide cylinder 19 fixed in the side cavity 10 and a pull rod 20 fixed to the connecting plate 18. The pull rod 20 is slidably fitted with the guide cylinder 19 and penetrates to the outside of the housing 1;

[0056] Among them, the pull rod 20 is also fixed to a convex ring 21 slidably arranged inside the guide cylinder 19. The guide cylinder 19 is provided with a second cylindrical spring 22 sleeved on the outer periphery of the pull rod 20. One end of the second cylindrical spring 22 is connected to the convex ring 21, and the other end is connected to the inner wall of the guide cylinder 19.

[0057] When it is necessary to remove the cover body 5 to inspect and repair the power supply component in the hysteresis chamber 9, the staff can pull the pull rod 20 toward the outside of the shell 1. Specifically, when the pull rod 20 is pulled toward the outside of the shell 1, the pull rod 20 will drive the connecting plate 18 and the two driving members 17 to move together. Since the driving member 17 is arranged in a hook shape, the driving member 17 will hook the connecting shaft 16 when it moves, so that the connecting shaft 16 drives the two locking members 12 to be withdrawn from the limiting groove 1102, and the limiting effect of the locking member 12 on the protrusion 11 is released. Then, the pull rod 20 continues to move, and the top cover mechanism will be triggered to apply a top thrust to the unlocked cover body 5 at this time, so that the cover body 5 can fall off from the shell 1 smoothly.

[0058] The top cover mechanism includes a cross bar 23 fixedly mounted on the connecting plate 18, a frame-shaped portion 24 formed at one end of the cross bar 23 away from the connecting plate 18, and a top bar 25 slidably arranged in the frame-shaped portion 24, and a column 26 is fixedly arranged at one end of the top bar 25 away from the cover body 5;

[0059] Among them, a movement guide plate 27 is also fixedly provided in the side cavity 10, and a slide groove adapted to the column 26 is provided on the movement guide plate 27. The column 26 passes through the slide groove and is slidably connected to the movement guide plate 27. The slide groove includes a connected straight through groove 2701 and an inclined through groove 2702.

[0060] In the process of pulling the pull rod 20 toward the outside of the shell 1, the connecting plate 18 will drive the push rod 25 to move together through the cross bar 23 and the frame-shaped part 24. Correspondingly, the push rod 25 will drive the column 26 to slide in the straight through groove 2701 and the inclined through groove 2702 in sequence. After the locking member 12 is pulled out of the limiting groove 1102, the column 26 will enter the inclined through groove 2702. Then, the column 26 will slide with the movement guide plate 27 through the inclined through groove 2702. Under the guidance of the frame-shaped part 24, the push rod 25 will approach the cover body 5. Then, the end of the push rod 25 away from the column 26 can apply a pushing force to the cover body 5, so as to facilitate the separation of the cover body 5 from the shell 1.

[0061] Street lamp module, street lamp and system including the street lamp module

[0062] As another embodiment of the present invention, a street lamp is also provided, the street lamp comprises the street lamp module, and also comprises a sleeve 6 fixed to the bottom of the housing 1, and the bottom of the housing 1 is provided with a mounting groove 101 adapted to the sleeve 6, and the sleeve 6 is provided with a threaded hole 601;

[0063] During actual deployment, the sleeve 6 may be sleeved onto the top of the lamp pole, and then the sleeve 6 and the lamp pole may be fixed by bolts through the threaded holes 601 .

[0064] A street lamp system is also proposed, which comprises the street lamp.

[0065] The street lamp module is applied in practice. When in use, the cover body 5 is locked by the elastic locking mechanism. The staff pushes the cover body 5 into the hysteresis cavity 9 to complete the quick assembly of the cover body 5 and the shell 1. When the power supply component in the hysteresis cavity 9 needs to be inspected and repaired, it is only necessary to control the pull-out unlocking mechanism to prompt the elastic locking mechanism to unlock the cover body 5. At the same time, the top cover mechanism can ensure the smooth separation of the cover body 5 and the shell 1. Therefore, when performing assembly and disassembly work, the staff does not need to rely on tools, which brings convenience to the maintenance workers. At the same time, reducing the use of tools can also effectively improve the safety of high-altitude operations.

[0066] Furthermore, when the street lamp system is applied in practice, relevant sensor technology, single-chip microcomputer control, communication technology, and intelligent management can be selected according to actual needs to realize the control analysis of the circuit in the system;

[0067] Specifically, regarding the intelligence of the system, various sensors can be used, such as light sensors, environmental monitoring sensors, etc. These sensors can detect changes in the surrounding environment, such as light intensity, temperature and humidity, and transmit these data to the control system in real time;

[0068] Secondly, a single-chip microcomputer can be used as the main control unit. For example, a multifunctional intelligent street light control system based on a 51 single-chip microcomputer includes a light intensity detection module, a key input module, an audio and video alarm module, etc., which can realize functions such as time setting and light threshold setting. Similarly, a street light controller based on an STM32 single-chip microcomputer also has multiple modes such as time control, photosensitive control and manual control;

[0069] Furthermore, advanced communication technologies such as NB-IoT, ZigBee, LoRa, etc. can also be used to achieve remote monitoring and control. For example, the NB-IoT-based smart street light control system can not only adjust the brightness of the street lights, but also provide fault alarms. The smart street light system uses a combination of multiple communication technologies to achieve efficient and stable remote monitoring and management functions. Different communication technologies have their own advantages, and the appropriate communication method can be selected according to the specific application scenario to meet different needs;

[0070] In addition, the application of Internet of Things technology makes the street lamp control system more intelligent, which can realize functions such as remote control, remote measurement, remote communication, remote adjustment and remote viewing. This intelligent management not only improves the management efficiency of street lamps, but also reduces energy consumption.

[0071] The design of street light circuits includes power supply circuits, drive circuits, and control circuits. For example, in a solar street light system, photovoltaic cells charge batteries during the day, and batteries provide power for street light lighting at night. The design of LED street light power supplies involves the selection of step-down capacitor values, rectification and filtering circuits, etc.

[0072] To achieve automatic control, the output of the Schmitt trigger can be controlled by sensing the external light intensity through a photoresistor, thereby controlling the switch of the street light. In addition, automatic control circuits can also be realized through components such as relays and bidirectional thyristors.

[0073] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0074] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
