Description

Technical Field

[0001] The utility model relates to the field of sunshades, in particular to an automatic sunshade temperature control device and its temperature control circuit. Background Art

[0002] The sunshade has a comprehensive external sunshade function, which can effectively block the radiation of ultraviolet rays, reduce the indoor temperature, reduce the air-conditioning load, and has an energy-saving effect. Most traditional sunshades are retracted and extended manually or, although electrically retractable, require manual control. For some locations that need to shade at regular times or according to the ambient temperature, it is necessary for people to go there on time and operate the sunshade, which is rather inconvenient. Summary of the Invention

[0003] In order to solve the above problems, the first object of the utility model is to provide an automatic sunshade temperature control circuit, which can control the expansion and contraction of the automatic sunshade based on the current ambient temperature, realize automatic control, replace manual control, and is more convenient to use.

[0004] In order to achieve the above object, the utility model adopts the following technical solutions:

[0005] The automatic sunshade temperature control circuit is characterized in that: it includes a power supply arranged on the main circuit, a driving motor for controlling the expansion and contraction of the automatic sunshade, a thermostat for detecting the ambient temperature, and a first limit switch and a second limit switch for respectively detecting and feedbacking the unfolded state and the retracted state of the automatic sunshade; the driving motor is simultaneously connected to a forward driving circuit for controlling the forward rotation of the driving motor and a reverse driving circuit for controlling the reverse rotation of the driving motor; the forward driving circuit and the reverse driving circuit are connected to the main circuit in parallel through two groups of relays; the first limit switch and the second limit switch are respectively arranged on the forward driving circuit and the reverse driving circuit, and the thermostat is connected to control the two groups of relays for turning on or off the forward driving circuit and the reverse driving circuit.

[0006] The utility model adopts the above technical solutions, which relate to an automatic sunshade temperature control circuit. The power supply in the automatic sunshade temperature control circuit is arranged in the main circuit and serves as the energy supply component of the whole temperature control circuit. The driving motor controls the expansion and contraction of the automatic sunshade by the forward and reverse rotation of its output end, and the thermostat is used to detect the ambient temperature.

[0007] Before use, set the temperature thresholds on the thermostat, including the deployment threshold and the closing threshold, with the deployment threshold being higher than the closing threshold. When the ambient temperature detected by the thermostat is higher than the deployment threshold, the thermostat controls two groups of relays to connect the forward drive circuit (the reverse drive circuit is disconnected), and at this time, the drive motor rotates forward to deploy the automatic sunshade until the automatic sunshade triggers the first limit switch, and the automatic sunshade is adjusted in place for deployment, and the motor stops. When the ambient temperature detected by the thermostat is lower than the closing threshold, the thermostat controls two groups of relays to connect the reverse drive circuit (the forward drive circuit is disconnected), and at this time, the drive motor rotates in reverse to retract the automatic sunshade until the automatic sunshade triggers the second limit switch, and the automatic sunshade is adjusted in place for retraction, and the motor stops.

[0008] Based on the above solution, the temperature control circuit of this automatic sunshade can control the expansion and contraction of the automatic sunshade based on the current ambient temperature, realizing automatic control, replacing manual control, and being more convenient to use.

[0009] In a further solution, the two groups of relays are connected in parallel to the thermostat through a control circuit, and the thermostat is connected in parallel across the power supply terminals. The thermostat controls the two groups of relays through the control circuit, thereby controlling the on and off of the forward drive circuit and the reverse drive circuit.

[0010] In a specific implementation, the relay is a five-pin relay. The relay includes a terminal 1 connected to the main circuit, and terminals 2 and 3 for connecting to the control circuit, and terminals 5 and 4 for connecting to the forward drive circuit and the reverse drive circuit respectively; the thermostat controls whether the terminals 2 and 3 of the two groups of relays are energized, thereby controlling the connection of the forward drive circuit and the reverse drive circuit. In this solution, when the thermostat controls the terminals 2 and 3 of the relay to be energized, the terminal 1 of the relay is connected to the terminal 5, that is, the forward drive circuit is connected, and the drive motor rotates forward to deploy the automatic sunshade. When the thermostat controls the terminals 2 and 3 of the relay not to be energized, the terminal 1 of the relay is connected to the terminal 4, that is, the reverse drive circuit is connected, and the drive motor rotates in reverse to retract the automatic sunshade.

[0011] The second object of the present utility model is to provide an automatic sunshade temperature control device, adopting the above-mentioned automatic sunshade temperature control circuit. In a further preferred solution, a first reel and a second reel are positioned on the frame of the automatic sunshade, and a plurality of annular pull ropes are wound between the first reel and the second reel; the drive motor drives the first reel to rotate, one end of the awning cloth of the automatic sunshade is fixed on the annular pull rope, and the first limit switch and the second limit switch are respectively arranged on the frame at both ends of the annular pull rope. In this solution, during the forward or reverse rotation of the drive motor, the first reel is driven to rotate, thereby driving the annular pull rope to run between the first reel and the second reel, and one end of the awning cloth moves with the annular pull rope to realize deployment or retraction.

[0012] The number of arrangements of the annular draw rope in the above solution can be set based on the length of the tarpaulin.

[0013] In a specific solution, the first reel is a driving reel, the second reel is a fixed reel or a driven reel, and the annular draw rope winds around the first reel at least one turn, preferably two turns or more, to ensure the connection stability between the annular draw rope and the first reel.

[0014] In a specific solution, a pull rod is arranged on the outer end of the tarpaulin of the movable sunshade, and the pull rod is connected to the annular draw rope; the pull rod is used to trigger the first limit switch and the second limit switch. The pull rod ensures the flatness during the movement of the front end of the tarpaulin and can be used to trigger the first limit switch and the second limit switch on the frame. In a further solution, the first limit switch and the second limit switch are arranged on the frames on both sides of the tarpaulin, and the pull rod extends out of both ends of the tarpaulin to trigger the first limit switch and the second limit switch.

[0023] Embodiment 1:

[0024] Such as Figure 1As shown in the figure, this embodiment relates to an automatic sunshade temperature control circuit, which includes a power supply 10 arranged on the main circuit a, a drive motor 11 for controlling the expansion and contraction of the automatic sunshade, a thermostat 12 for detecting the ambient temperature, and a first limit switch 13 and a second limit switch 14 for detecting and feeding back the deployed state and retracted state of the automatic sunshade respectively. The drive motor 11 is simultaneously connected to a forward drive circuit b for controlling the forward rotation of the drive motor 11 and a reverse drive circuit c for controlling the reverse rotation of the drive motor 11. The forward drive circuit b and the reverse drive circuit c are connected in parallel to the main circuit a through two groups of relays 15. The first limit switch 13 and the second limit switch 14 are respectively arranged on the forward drive circuit b and the reverse drive circuit c. The thermostat 12 is controlled to connect the two groups of relays 15 to turn on or off the forward drive circuit b and the reverse drive circuit c. In a further solution, the two groups of relays 15 are connected in parallel to the thermostat 12 through a control circuit d, and the thermostat 12 is connected in parallel across the power supply 10. The thermostat 12 controls the two groups of relays 15 through a control circuit to control the on-off of the forward drive circuit b and the reverse drive circuit c.

[0025] The power supply 10 in this automatic sunshade temperature control circuit is arranged in the main circuit a and serves as the energy supply component of the entire temperature control circuit. The drive motor 11 controls the expansion and contraction of the automatic sunshade by the forward and reverse rotation of its output end, and the thermostat 12 is used to detect the ambient temperature. Before use, temperature thresholds, including an expansion threshold and a closing threshold, are set on the thermostat 12, and the expansion threshold is higher than the closing threshold. When the ambient temperature detected by the thermostat 12 is higher than the expansion threshold, the thermostat 12 controls the connection of the two groups of relays 15 to turn on the forward drive circuit b [the reverse drive circuit c is disconnected]. At this time, the drive motor 11 rotates forward to deploy the automatic sunshade until the automatic sunshade triggers the first limit switch 13, and the automatic sunshade is adjusted to the deployed position and the motor stops. When the ambient temperature detected by the thermostat 12 is lower than the closing threshold, the thermostat 12 controls the connection of the two groups of relays 15 to turn on the reverse drive circuit c [the forward drive circuit b is disconnected]. At this time, the drive motor 11 rotates in reverse to retract the automatic sunshade until the automatic sunshade triggers the second limit switch 14, and the automatic sunshade is adjusted to the retracted position and the motor stops. The first limit switch 13 and the second limit switch 14 in the above solution are in the off state when the automatic sunshade touches them and are in the on state when the automatic sunshade separates from them.

[0026] Based on the above solution, this automatic sunshade temperature control circuit can control the expansion and contraction of the automatic sunshade based on the current ambient temperature, realizing automatic control, replacing manual control, and being more convenient to use.

[0027] In Figure 1In the specific implementation shown, the relay 15 is a five-pin relay. The relay 15 includes a terminal 1 connected to the main circuit a, terminals 2 and 3 for connecting to the first control branch d and the second control branch e, and terminals 5 and 4 for connecting to the forward drive circuit b and the reverse drive circuit c respectively. The thermostat 12 controls whether the terminals 2 and 3 of the two relays 15 are energized, thereby controlling the on / off of the forward drive circuit b and the reverse drive circuit c. In this solution, when the thermostat 12 controls the terminals 2 and 3 of the relay 15 to be energized, the terminal 1 of the relay 15 is connected to the terminal 5, that is, the forward drive circuit b is connected, and the drive motor 11 rotates forward to deploy the automatic sunshade. When the ambient temperature drops below the closing threshold, the thermostat 12 controls the terminals 2 and 3 of the relay 15 to be de-energized, and the terminal 1 of the relay 15 is connected to the terminal 4, that is, the reverse drive circuit c is connected, and the drive motor 11 rotates in reverse to retract the automatic sunshade.

[0028] For the circuit components described in the above solution, the following components can be specifically used:

[0029] Limit switch, MAE type self-resetting, press to close, reset to open and connect.

[0030] Relay, original Huike 12V 5-pin automotive relay.

[0031] Motor: JS50 DC micro 12V stirring and rotating brush motor.

[0032] Thermostat: XH-W3001 intelligent digital thermostat microcomputer temperature control instrument temperature switch.

[0033] Power supply: Photovoltaic 12V mobile power supply.

[0034] Embodiment 2:

[0035] As Figure 2 and 3 shown, this embodiment provides an automatic sunshade temperature control device, which adopts the automatic sunshade temperature control circuit described in Embodiment 1. In a further preferred solution, a first reel 31 and a second reel 32 are positioned on the frame 30 of the automatic sunshade, and an annular pull rope 33 is wound between the first reel 31 and the second reel 32. The drive motor 11 drives the first reel 31 to rotate, one end of the awning cloth 34 of the automatic sunshade is fixed on the annular pull rope 33, and the first limit switch 13 and the second limit switch 14 are respectively arranged on the frame at both ends of the annular pull rope 33.

[0036] The arrangement quantity of the annular pull rope in the above solution can be set based on the length of the awning cloth.

[0037] In a specific solution, the first reel is a driving reel, the second reel is a fixed reel or a driven reel, and the annular pulling rope 33 is wound around the first reel 31 at least twice to ensure the connection stability between the annular pulling rope 33 and the first reel 31, so that the driving reel can drive the annular pulling rope 33 to run. A pull rod 36 is arranged on the outer end of the awning cloth 34 of the movable awning, and the pull rod 36 is connected to the annular pulling rope 33; the pull rod 36 is used to trigger the first limit switch 13 and the second limit switch 14. The pull rod 36 ensures the flatness of the front end of the awning cloth 34 during the moving process and can be used to trigger the first limit switch 13 and the second limit switch 14 on the frame body.

[0038] Further, the first limit switch 13 and the second limit switch 14 are arranged on the frame body 30 on both sides of the awning cloth 34, and the pull rod 36 extends out of the two end parts of the awning cloth 34 to trigger the first limit switch 13 and the second limit switch 14. Arranging the first limit switch 13 and the second limit switch 14 on both sides can reduce interference, but the installation position requires that the pull rod can provide sufficient pull rod pressure to ensure that the first limit switch 13 and the second limit switch 14 can be triggered.

[0039] In this solution, during the forward or reverse rotation of the driving motor 11, the first reel 31 is driven to rotate, and then the annular pulling rope 33 is driven to run between the first reel 31 and the second reel 32, and the outer end of the awning cloth 34 moves along with the annular pulling rope 33 to realize unfolding or folding.

[0040] In the description of this specification, the description with reference to terms such as "an embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
