Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to low-power wireless local area extensions. Background Art

[0002] With the rapid development of Internet of Things technology, low-power wireless communication technology has been widely used in smart home, industrial automation, environmental monitoring and other fields. When monitoring air quality or soil humidity, low-power wireless area extensions need to be placed outdoors.

[0003] For low-power wireless zone extensions, due to their relatively low power consumption, additional cooling measures are usually not required. However, in extremely high temperature environments (such as high temperatures in summer), if the device is running for a long time and the heat dissipation is poor, it may cause the device performance to degrade or even be damaged.

[0004] Therefore, how to improve the heat dissipation capacity of low-power wireless local extensions while maintaining a high temperature environment to ensure their stable operation and extend their service life has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] In order to dissipate heat for a low-power wireless local extension in a high-temperature environment, the present application provides a low-power wireless local extension.

[0006] The low-power wireless regional extension provided in this application adopts the following technical solutions:

[0007] A low-power wireless regional extension includes a cabinet, a baffle and a positioning component. A vent is opened on the side wall of the cabinet. One side of the baffle is hinged to the side wall of the cabinet. The baffle is used to cover the surface of the vent. The vent has an open and closed state, and the positioning component is used to switch the open and closed state of the vent.

[0008] By adopting the above-mentioned technical solution, the open / closed state of the vent is switched through the positioning component. When the external environment is in a high temperature state, the vent is switched to the open state, so that the outside wind can enter the inside of the cabinet to dissipate the heat inside, thereby reducing the damage to the electronic components caused by long-term operation of the equipment; when the outside world is in a rainy day or non-summer, the vent is switched to the closed state. At this time, the baffle covers the vent, which can reduce the entry of external dust and moisture into the extension, keep the electronic components from damage, and extend the service life of the equipment.

[0009] Optionally, the positioning assembly includes a torsion spring and a positioning frame, the torsion spring is installed at the hinge between the baffle and the cabinet, the elastic force of the torsion spring is used to drive the baffle to cover the surface of the vent under normal conditions, and the vent is in a closed state; plug plates are provided on both sides of the positioning frame, and slots for plugging the plug plates are provided on the sides where the baffle and the cabinet are close to each other; when the plug plate is plugged into the slot, the vent is in an open state.

[0010] By adopting the above-mentioned technical solution, by setting a torsion spring, the elastic force of the torsion spring can drive the baffle to cover the surface of the vent under normal conditions, so that the vent is in a closed state, reducing the entry of external dust and rainwater into the interior of the cabinet; when the vent needs to be switched to an open state, the baffle is rotated along the hinge between itself and the cabinet, so that there is a distance between the baffle and the cabinet, and then the plug-in plates on both sides of the positioning frame are respectively inserted into the slots, so that a stable triangular structure is formed between the baffle, the positioning frame and the cabinet, so as to keep the vent in an open state, thereby improving the heat dissipation effect inside the cabinet.

[0011] Optionally, the surface of the positioning frame is covered with a filter.

[0012] By adopting the above technical solution and setting a filter, dust and insects can be blocked, reducing the possibility of them entering the cabinet, so as to maintain the stability of the operation of the equipment.

[0013] Optionally, water baffles are provided on both sides of the positioning frame in the length direction, and the water baffles are abutted against the bottom wall of the baffle.

[0014] By adopting the above-mentioned technical solution, water baffles are arranged on both sides of the length of the positioning frame. The water baffles can be folded into the gap between the two sides of the baffle length and the cabinet, thereby reducing the situation where external rainwater splashes into the cabinet when the vents are not closed in time, thereby improving the service life of electronic components in the cabinet.

[0015] Optionally, the outer wall of the plug board is wrapped with a rubber layer.

[0016] By adopting the above technical solution and providing a rubber layer, the stability of the plug board inserted into the slot can be increased, and the free movement of the positioning frame on the cabinet can be reduced when the vent is in the open state.

[0017] Optionally, the vents are provided in multiple groups, and all the vents are spaced apart along the height direction of the cabinet; a gear is provided on one side of the baffle, and a rack is slidably installed on the side wall of the cabinet; and all the gears are meshed with the rack.

[0018] By adopting the above-mentioned technical solution, by rotating one of the baffles, the gear of the baffle can be meshed with the rack, thereby causing the rack to slide; since all the baffles on one side of the cabinet are provided with gears, and all the gears are meshed with the rack, all the baffles can be rotated at the same time, which facilitates the opening of the vents and improves work efficiency.

[0019] Optionally, the positioning assembly includes a cylinder, and an output shaft of the cylinder is connected to the rack.

[0020] By adopting the above technical solution, by pulling the rack through the movable plug of the cylinder, all the baffles on one side of the cabinet can be rotated at the same time, so that the open / closed state of the vents on one side of the cabinet can be switched, thereby improving work efficiency.

[0021] Optionally, a temperature sensor is provided inside the cabinet, and the temperature sensor is electrically connected to the cylinder.

[0022] By adopting the above-mentioned technical solution, when the temperature sensor senses that the temperature inside the cabinet is high, the temperature sensor transmits an electrical signal to the temperature sensor, so that the vents are switched to the open state; and when the temperature inside the cabinet drops, the cylinder is restarted to promptly close all the vents, thereby reducing the possibility of external dust entering the cabinet.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the baffle and positioning component, and using the positioning component to switch the vent to the open state, the outside wind can enter the cabinet to dissipate heat inside, reducing the damage to the electronic components caused by long-term operation of the equipment; when the positioning component is used to switch the vent to the closed state, the baffle covers the vent, which can reduce the outside dust and moisture from entering the extension, keep the electronic components from damage, and extend the service life of the equipment;

[0025] 2. By setting gears and racks and pulling the racks, since all gears are meshed with the racks, all baffles can be rotated at the same time, so that the vents on one side of the cabinet can be switched between open / closed states at the same time, thereby improving work efficiency.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Embodiment 1:

[0034] The embodiment of the present application discloses a low-power wireless zone extension.

[0035] Reference Figure 1 and Figure 2 The low-power wireless regional extension includes a cabinet 1, a baffle 2 and a positioning component 3. The cabinet 1 is provided with a plurality of vents 11, all of which are arranged at intervals along the height direction of the cabinet 1, and the extension direction of all of the vents 11 is parallel to the ground; the side wall of the cabinet 1 is provided with two mounting plates 12, which are respectively located on both sides of the length direction of the vent 11, and the two ends of the baffle 2 are rotatably connected with the two mounting plates 12 through a rotating shaft 21. The vent 11 has an open and closed state, and the positioning component 3 is used to switch the open and closed state of the vent 11.

[0036] Reference Figure 2 and Figure 3 The positioning assembly 3 includes a torsion spring 31, a positioning frame 32 and a filter 33. The torsion spring 31 is sleeved on the rotating shaft 21, and the two ends of the torsion spring 31 are respectively connected to the baffle 2 and the mounting plate 12. The elastic force of the torsion spring 31 is used to drive the baffle 2 to cover under normal conditions so that the vent 11 is in a closed state.

[0037] Reference Figure 3, plug-in plates 34 are provided on opposite sides of the positioning frame 32, and the surface of the plug-in plates 34 is wrapped with a rubber layer 35, and slots 22 for plugging in the plug-in plates 34 are provided on the side where the baffle 2 and the cabinet 1 are close to each other; when the vent 11 is switched to the open state, the baffle 2 is rotated toward the side away from the vent 11, so that the baffle 2 and the slot 22 of the cabinet 1 are exposed to the outside; at this time, the plug-in plates 34 on both sides of the positioning frame 32 are plugged into the slot 22 in an interference fit manner, so that a stable triangular structure can be formed between the positioning frame 32, the baffle 2 and the cabinet 1, so that the outside air can enter the cabinet 1 through the positioning frame 32 and the vent 11 in turn, so as to dissipate the heat of the electronic components inside the cabinet 1.

[0038] In this embodiment, the inner diameter of the slot 22 located on the baffle 2 gradually decreases from the side close to the baffle 2 to the side away from the baffle 2; when the positioning frame 32 is installed between the baffle 2 and the cabinet 1, the positioning frame 32 is first connected to the baffle 2, and then the plug-in plate 34 on one side of the positioning frame 32 is plugged into the slot 22 of the cabinet 1; this installation method can reduce the possibility of the installation frame detaching from between the cabinet 1 and the baffle 2.

[0039] Reference Figure 2 Water baffles 36 are provided on both sides of the positioning frame 32, and the water baffles 36 can abut against the side of the baffle 2 close to the cabinet 1, thereby reducing the possibility of rainwater entering the cabinet 1 through the gap between the end of the baffle 2 and the cabinet 1 when it rains.

[0040] The filter 33 covers the surface of the positioning frame 32. By setting the filter 33, dust and insects can be blocked and the possibility of them entering the cabinet 1 is reduced, so as to maintain the stability of the operation of the equipment.

[0041] The implementation principle of Example 1 of the present application is:

[0042] When the external environment is at a high temperature, the vent 11 is switched to the open state, so that the external wind can enter the cabinet 1 to dissipate the heat inside, thereby reducing the damage to the electronic components caused by long-term operation of the equipment; when the outside world is in a rainy day or non-summer, the vent 11 is switched to the closed state. At this time, the baffle 2 covers the vent 11, which can reduce the external dust and moisture from entering the extension, keep the electronic components from damage, and extend the service life of the equipment.

[0043] Embodiment 2:

[0044] The embodiment of the present application discloses a low-power wireless zone extension.

[0045] Reference Figure 4 and Figure 5The difference between Example 2 of the present application and Example 1 is that: a rack 13 is slidably installed on the side wall of the cabinet 1, and the sliding direction of the rack 13 is in the same direction as the height direction of the cabinet 1; the rotating shaft 21 on one side of the baffle 2 passes through the mounting plate 12 and is exposed to the outside, and the rotating shaft 21 is provided with a gear 38, and the gear 38 on one side of the baffle 2 is meshed with the rack 13.

[0046] The positioning assembly 3 includes a cylinder 39 and a temperature sensor. The cylinder 39 is installed on the side wall of the cabinet 1, and the movable plug of the cylinder 39 is fixed to the rack 13; the temperature sensor is installed inside the cabinet 1 and is electrically connected to the cylinder 39.

[0047] The implementation principle of Example 2 of the present application is:

[0048] When the temperature sensor senses that the temperature inside the cabinet 1 is high, the temperature sensor transmits an electrical signal to the temperature sensor, and pulls the rack 13 through the movable plug of the cylinder 39. Since all the gears 38 on one side of the cabinet 1 are meshed with the rack 13, the lower baffle 2 can rotate when the rack 13 is pulled, so that all the vents 11 can be in an open state to dissipate heat inside the cabinet 1; and when the temperature inside the cabinet 1 drops, the cylinder 39 is restarted to close all the vents 11 in time to reduce the possibility of external dust entering the cabinet 1.

[0049] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
