The relative movement between the first mounting bracket and the shell can drive the sensor to switch between a first position and a second position. The shell has a first mounting surface. When the sensor is in the first position, the distance between the sensor and the first mounting surface is a first distance. When the sensor is in the second position, the distance between the sensor and the first mounting surface is a second distance. The first distance is smaller than the second distance.

Description

Electronic devices and their control methods Technical Field

[0001] This application belongs to the field of electronic device design technology, specifically relating to an electronic device and a control method for the electronic device. Background Technology

[0002] Depending on user needs, electronic devices are typically equipped with sensors that enable them to perform certain preset detection functions. These devices are usually mounted on a foundation for subsequent operation. Taking a thermostat as an example, thermostats are usually mounted on a wall (in this case, the wall is the mounting base). The temperature sensor within the thermostat is relatively close to the wall, making it more susceptible to heat transfer from the wall, ultimately leading to lower detection accuracy. Conversely, when the thermostat is mounted on a wall, the heat generated during its operation is absorbed by the wall, resulting in a higher wall temperature that, in turn, heats the temperature sensor, ultimately affecting its detection accuracy.

[0003] Of course, this is not limited to temperature controllers. Other electronic devices equipped with sensors also suffer from poor detection accuracy when installed on a mounting base. This is because the sensors are easily affected by the mounting base (for example, the heat transferred from the mounting base can cause the sensor temperature to become too high, affecting its detection performance). Summary of the Invention

[0004] This invention discloses an electronic device and its control method to solve the problem that related electronic devices are easily affected by the installation foundation when their sensors are performing detection, and thus cannot adapt to scenarios with high detection accuracy requirements.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] In a first aspect, embodiments of this application disclose an electronic device, including a housing, a sensor, and a first mounting bracket;

[0007] The sensor is mounted on the first mounting bracket, which is movably mounted on the housing. The relative movement between the first mounting bracket and the housing can cause the sensor to switch between a first position and a second position. The housing has a first mounting surface, which is used to connect to the mounting base of the electronic device.

[0008] When the sensor is in the first position, the distance between the sensor and the first mounting surface is the first distance;

[0009] When the sensor is in the second position, the distance between the sensor and the first mounting surface is the second distance;

[0010] The first distance is less than the second distance.

[0011] Secondly, embodiments of this application disclose a control method for an electronic device, wherein the electronic device is the aforementioned electronic device, and the control method includes:

[0012] Upon receiving the first information, and in response to the first information, control the sensor to move to the first position;

[0013] Upon receiving the second information, and in response to the second information, control the sensor to move to the second position.

[0014] Thirdly, embodiments of this application disclose a control method for an electronic device, wherein the electronic device is the electronic device described above, and the electronic device further includes a display screen disposed on the housing, and the control method includes:

[0015] Obtain the detection compensation value of the sensor;

[0016] The sensor is maintained in the first position, and the display screen is controlled to display the sum of the detection compensation value and the actual detection value detected by the sensor at the first position as the detection result; wherein:

[0017] The step of obtaining the detection compensation value of the sensor includes:

[0018] Control the sensor to move to the first position and acquire the first detection value detected by the sensor at the first position;

[0019] Control the sensor to move to the second position and acquire the second detection value detected by the sensor at the second position;

[0020] Calculate the difference between the first detection value and the second detection value, and use the difference as the detection compensation value.

[0021] The technical solution adopted in this invention can achieve the following technical effects:

[0022] The electronic device disclosed in this application improves the structure of electronic devices in related technologies by movably mounting a first mounting bracket on a housing. This allows the sensor to rotate with the first mounting bracket relative to the housing, switching between a first position and a second position, thereby changing the sensor's distance from the first mounting surface. In practical operation, in scenarios where high sensor detection accuracy is not required, the first mounting bracket can move the sensor to the first position, allowing it to operate closer to the mounting base. In scenarios where high sensor detection accuracy is required, the first mounting bracket can move the sensor to the second position, allowing it to operate further away from the mounting base. This effectively mitigates the impact of the mounting base on detection accuracy, achieving a more precise detection result. Furthermore, operating from the second position, farther from the mounting base, avoids the impact of the mounting base on the sensor's response speed. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 8. This application discloses an electronic device, which includes a housing 100, a sensor 200, and a first mounting bracket 300.

[0032] The housing 100 is the outer main component of the electronic device, providing mounting positions and protection for other components of the electronic device. The housing 100 can be made of metal or plastic; this application embodiment does not limit the specific material of the housing 100. In this application embodiment, the housing 100 can be an integral structure or a split structure. The housing 100 has a first mounting surface 111, which is used to connect with the mounting base of the electronic device (e.g., a wall, ceiling, or cabinet), thereby enabling the electronic device to be mounted on the mounting base. The first mounting surface 111 and the mounting base of the electronic device can be connected by methods such as adhesive bonding, connector connection, or snap-fit.

[0033] As shown in Figure 1, the housing 100 may include a front housing 110 and a rear housing 120, which are connected together. The front housing 110 may include a first mounting surface.

[0034] Sensor 200 is a detection device of electronic equipment, enabling the electronic equipment to have at least one preset detection function. There can be various types of sensor 200, such as temperature sensor, humidity sensor, smoke sensor, etc. The embodiments of this application do not limit the specific type of sensor 200.

[0035] The first mounting bracket 300 is used to mount the sensor 200. Specifically, the sensor 200 can be fixed to the first mounting bracket 300, or it can be movably mounted on the first mounting bracket 300 within the range allowed by installation requirements. Of course, to ensure stability after installation, the sensor 200 can be fixedly connected to the first mounting bracket 300 by means of snap-fit, adhesive, or connection with connectors (such as threaded connectors). Regardless of the method, in this embodiment, the connection between the sensor 200 and the first mounting bracket 300 needs to ensure that the sensor 200 can move with the first mounting bracket 300.

[0036] The first mounting bracket 300 is movably mounted on the housing 100, thereby enabling it to move relative to the housing 100. Specifically, the first mounting bracket 300 can be rotatably mounted on the housing 100 or movablely mounted on the housing 100. The movement of the first mounting bracket 300 relative to the housing 100 can drive the sensor 200 to move, enabling the sensor 200 to switch between a first position and a second position.

[0037] When the sensor 200 is in the first position, the distance between the sensor 200 and the first mounting surface 111 is the first distance. In this case, the distance between the sensor 200 and the mounting base can be approximated as the first distance.

[0038] When the sensor 200 is in the second position, the distance between the sensor 200 and the first mounting surface 111 is the second distance. In this case, the distance between the sensor 200 and the mounting base can be approximated as the second distance.

[0039] In this embodiment, the first distance is less than the second distance, meaning that the sensor 200 in the second position is farther from the mounting base.

[0040] The electronic device disclosed in this application improves the structure of electronic devices in related technologies by movably mounting a first mounting bracket 300 on the housing 100. This allows the sensor 200 to rotate with the first mounting bracket 300 relative to the housing 100, switching between a first position and a second position, thereby changing the distance between the sensor 200 and the first mounting surface 111. In practical operation, if the detection accuracy requirement of the sensor 200 is not high, the first mounting bracket 300 can move the sensor 200 to the first position, allowing it to operate closer to the mounting base. If the detection accuracy requirement of the sensor 200 is high, the first mounting bracket 300 can move the sensor 200 to the second position, allowing it to operate farther from the mounting base. This effectively mitigates the influence of the mounting base on the detection accuracy, achieving a more precise detection effect.

[0041] Of course, since it can work from a second position far away from the installation base, it can avoid the influence of the installation base on the response speed of the sensor during detection.

[0042] As described above, the sensor 200 is mounted on the first mounting bracket 300, thereby enabling it to move relative to the housing 100 along with the first mounting bracket 300. Specifically, the first mounting bracket 300 can be located entirely outside or entirely inside the housing 100, as long as its movement relative to the housing 100 can cause the sensor 200 to move towards or away from the first mounting surface 111, thereby changing the distance between the sensor 200 and the first mounting surface 111 to adjust the detection position. This application does not limit whether the sensor 200 and the first mounting bracket 300 are inside or outside the housing 100.

[0043] Referring again to Figures 1 to 3, in this embodiment, the housing 100 has an inner cavity 112 and a through hole 113. The through hole 113 communicates with the inner cavity 112. The through hole 113 is formed on a first side surface 114 of the housing 100 adjacent to the first mounting surface 111. Normally, the front of the electronic device faces away from the first mounting surface 111; that is, the first mounting surface 111 is usually the back of the electronic device.

[0044] The electronic device disclosed in the embodiments of this application may further include a second mounting bracket 400, a first mounting bracket 300 movably disposed on the second mounting bracket 400, and the second mounting bracket 400 movably disposed on the housing 100, and can switch between an extended position and a retracted position. Of course, when the second mounting bracket 400 is in the extended position, at least a portion of the second mounting bracket 400 extends out of the housing 100, and when the second mounting bracket 400 is in the retracted position, the second mounting bracket 400 retracts into the housing 100.

[0045] During the movement of the second mounting bracket 400 between the extended position and the retracted position, it will drive the first mounting bracket 300 to move together, thereby causing the first mounting bracket 300 to drive the sensor 200 to move together.

[0046] When the second mounting bracket 400 is in the extended position, the first mounting bracket 300 is located outside the housing 100. The first mounting bracket 300, located outside the housing 100, can cause the sensor 200, also located outside the housing 100, to switch between a first position and a second position, thereby changing the distance between the sensor 200 and the first mounting surface 111. In the retracted position, the first mounting bracket 300 is located inside the housing 100, and the sensor 200 is exposed on the first side surface 114. During the retraction of the second mounting bracket 400, the distance between the sensor 200 and the first mounting surface 111 can be maintained at the first distance, or the distance between the sensor 200 and the first mounting surface 111 can change to the first distance. That is, after the second mounting bracket 400 has retracted completely, it ensures that the sensor 200 is at the first position with the first distance between it and the first mounting surface 111, thus enabling detection while exposed on the first side surface 114.

[0047] This structure allows the sensor 200 to switch between an extended and retracted position via the first mounting bracket 300 and the second mounting bracket 400. In the extended position, the sensor 200 is kept away from other components of the electronic device, thus preventing it from being affected by heat from those components. Especially when the sensor 200 is a temperature sensor, this structure not only protects it from the influence of the mounting base but also further protects it from the influence of other components of the electronic device.

[0048] After the electronic device is mounted on the mounting base, its front faces away from the mounting base. Since the first side 114 is located on a surface adjacent to the first mounting surface 111, it is not easily noticed by the user, thus improving the appearance of the electronic device. To ensure that the sensor 200 can move away from or towards the first mounting surface 111, this design first allows the sensor 200 and the first mounting bracket 300 to extend through the through hole 113 along with the second mounting bracket 400, thereby releasing the constraint of the housing 100. Then, with the second mounting bracket 400 in the extended position, the first mounting bracket 300, outside the housing 100, drives the sensor 200 from the first position to the second position. During the retraction of the second mounting bracket 400, the sensor 200 needs to move from the second position to the first position under the influence of the first mounting bracket 300, so that the first mounting bracket 300 and the sensor 200 can retract through the through hole 113.

[0049] In the embodiments of this application, the movement of the first mounting bracket 300 relative to the housing 100, the movement of the second mounting bracket 400 relative to the housing 100, and the movement of the first mounting bracket 300 relative to the second mounting bracket 400 can be achieved by manual driving or by a driving mechanism. The embodiments of this application do not impose any restrictions.

[0050] In an optional embodiment, the electronic device may further include a drive mechanism 600, which is housed within the housing 100 and connected to the second mounting bracket 400 to drive the second mounting bracket 400 to switch between an extended position and a retracted position. The drive mechanism 600 enables intelligent movement of the second mounting bracket 400. The drive mechanism 600 can be of various types, such as a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, a linkage mechanism, or a motor drive mechanism.

[0051] As shown in Figure 3, the drive mechanism 600 may include a drive motor 610 and a transmission mechanism 620. The transmission mechanism 620 may include a gear 621 and a rack 622. The gear 621 is connected to the power output shaft of the drive motor 610, and the rack 622 is connected to the second mounting bracket 400. The gear 621 and rack 622 mesh. When the drive motor 610 rotates in the first direction, the drive motor 610 drives the second mounting bracket 400 to retract through the meshing of the gear 621 and rack 622. When the drive motor 610 rotates in the second direction, the drive motor 610 drives the second mounting bracket 400 to extend through the meshing of the gear 621 and rack 622. The first direction and the second direction are opposite.

[0052] In a further alternative embodiment, the first end of the first mounting bracket 300 is rotatably connected to the second mounting bracket 400, and the second end of the first mounting bracket 300 is a free end, with the sensor 200 disposed at the second end of the first mounting bracket 300. The electronic device disclosed in this application embodiment may further include an elastic element 500, which connects the second end of the first mounting bracket 300 to the second mounting bracket 400.

[0053] With the second mounting bracket 400 in the extended position, the elastic element 500 drives the first mounting bracket 300 to rotate to the second position. During the retraction of the second mounting bracket 400, the through hole 113 interferes with the first mounting bracket 300 to compress the elastic element 500, and the second mounting bracket 400 moves with the first mounting bracket 300 into the housing 100.

[0054] This solution changes the constraint on the elastic element 500 by whether the through hole 113 interferes with the first mounting bracket 300 during the movement of the second mounting bracket 400, thereby adjusting the position of the sensor 200. This allows the sensor 200 to adjust between the first and second positions more accurately to follow the position of the second mounting bracket 400. Specifically, when the second mounting bracket 400 is in an extended position that allows the sensor 200 to switch between the first and second positions, the sensor 200 is driven to switch to the second position more accurately; when the second mounting bracket 400 is retracted and does not allow the sensor 200 to switch to the second position, the sensor 200 is driven to switch to the first position more accurately.

[0055] In further technical solutions, the first mounting bracket 300 may be a hydraulic telescopic component, a pneumatic telescopic component, a shape memory alloy component, etc. The embodiments of this application do not limit the specific type of the first mounting bracket 300.

[0056] The second mounting bracket 400 has a groove 410. When the first mounting bracket 300 is in the first position, the first mounting bracket 300 and the second mounting bracket 400 form a receiving space, and the elastic member 500 is disposed within the receiving space. In this case, the first mounting bracket 300 and the second mounting bracket 400 can also form a receiving space to accommodate the elastic member 500, and allow the elastic member 500 to be disposed within the receiving space, thereby contributing to the compactness of the structure and preventing the overall structure formed by the first mounting bracket 300, the sensor 200 and the second mounting bracket 400 from occupying a large space.

[0057] As described above, the elastic element 500 can perform an elastic driving function. The elastic element 500 can be of various types, such as a telescopic spring, rubber band, or bent metal sheet. This application does not limit the specific type of elastic element 500. In one optional embodiment, the elastic element 500 can be a torsion spring. The first rotating arm of the torsion spring is connected to the second end of the first mounting bracket 300, and the second rotating arm of the torsion spring is connected to the second mounting bracket 400. In this case, during the elastic deformation of the torsion spring, the first and second rotating arms will rotate relative to each other, thus better adapting to the relative movement of the rotatably connected first and second mounting brackets 300 and 400, thereby achieving better driving.

[0058] To prevent the second mounting bracket 400 from retracting excessively, in one option, the housing 100 may include a first limiting portion 115, which, when the second mounting bracket 400 is in the retracted position, makes limiting contact with the first limiting portion 115 in the retraction direction. Specifically, the first limiting portion 115 may be a first limiting protrusion, and the second mounting bracket 400 may include a second limiting protrusion, which, when the second mounting bracket 400 is in the retracted position, makes limiting contact with the first limiting protrusion in the retraction direction.

[0059] To prevent the second mounting bracket 400 from over-extending, in one option, the housing 100 may include a second limiting portion 116. In the extended position, the second mounting bracket 400 and the second limiting portion 116 make limiting contact in the extension direction of the second mounting bracket 400. Specifically, the second limiting portion 116 may be a third limiting protrusion, and the second mounting bracket 400 may include a fourth limiting protrusion. When the second mounting bracket 400 is in the retracted position, the third limiting protrusion and the fourth limiting protrusion make limiting contact in the retraction direction.

[0060] In one alternative embodiment, the housing 100 may include a third limiting portion 117, and the second mounting bracket 400 may have a guide groove 420 extending along its telescopic direction. The third limiting portion 117 guides and engages with the guide groove 420 in the telescopic direction, and also limits and engages in a direction perpendicular to the telescopic direction and perpendicular to the orientation of the groove opening of the guide groove 420. This allows for limiting the second mounting bracket 400 in another dimension, ultimately improving the stability of the telescopic movement of the second mounting bracket 400 and preventing it from deviating from the direction of the telescopic movement. The third limiting portion 117 may be a fifth limiting protrusion.

[0061] Since the sensor 200 is in the second position, the distance between the sensor 200 and the first mounting surface is relatively large. Therefore, if a user approaches the electronic device, there is a possibility of collision with the sensor 200 and the first mounting bracket 300, which could damage the electronic device. To address this, in one alternative solution, when the distance between the user and the electronic device is less than a preset distance threshold, the second mounting bracket 400 moves to a retracted position. This causes the second mounting bracket 400 to move the first mounting bracket 300 and the sensor 200, ultimately moving the sensor 200 to a first position closer to the first mounting surface 111. This position brings the sensor closer to the mounting base and further away from the user, thus mitigating the risk of the user accidentally damaging the sensor 200.

[0062] Of course, electronic devices can be equipped with distance detection devices (such as laser ranging modules, infrared ranging modules, etc.). The distance detection device is used to detect the distance between the user and the electronic device. When the distance between the user and the electronic device is less than a preset distance threshold, the device directly controls the drive mechanism 600, so that the drive mechanism 600 drives the second mounting bracket 400, thereby driving the first mounting bracket 300 and the sensor 200 closer to the first mounting surface 111.

[0063] In this embodiment, the first mounting bracket 300 can be made of plastic, metal, or other materials. This embodiment does not limit the type of the first mounting bracket 300. The first mounting bracket 300 can be a metal bracket, such as an iron component or an aluminum bracket; this embodiment does not limit the specific material of the first mounting bracket 300.

[0064] In the electronic device disclosed in this application embodiment, the first mounting bracket 300 can be a non-metallic bracket, such as a plastic bracket. Since the plastic bracket is not a good conductor of heat, less heat generated by other components of the electronic device can be transferred to the sensor 200, thereby mitigating the adverse thermal effects on the sensor 200.

[0065] The electronic devices disclosed in this application can be of various types. For example, an electronic device can be a thermostat installed on an indoor wall (in this case, the installation base is an indoor wall) or a smoke detector. This application does not limit the specific type of electronic device.

[0066] In a specific application scenario, the electronic device disclosed in this application can be a thermostat that works with an air conditioner (e.g., a household water-cooled air conditioner). The air conditioner uses the temperature detected by the thermostat to determine whether the ambient (indoor) temperature has reached the set value, and then controls its own on / off state to achieve real-time room temperature control. In this case, the mounting base can be the air conditioner unit itself, or it can be other indoor mounting bases (e.g., an indoor wall).

[0067] Based on the electronic device disclosed in the embodiments of this application, the embodiments of this application further disclose a control method for the electronic device, the control method comprising:

[0068] Step A1: Receive the first message and, in response to the first information, control the sensor 200 to move to the first position.

[0069] Step A2: Receive the second message and, in response to the second message, control the sensor 200 to move to the third position.

[0070] Based on the electronic device disclosed in the embodiments of this application, this application further discloses a control method for the electronic device, wherein the electronic device includes a display screen 700 disposed on a housing 100. The control method includes:

[0071] Step B1: Obtain the detection compensation value of sensor 200.

[0072] This detection compensation value can be preset according to the experiment or calculated through detection. For example, step B1 may include:

[0073] Step B11: Control the sensor 200 to move to the first position and obtain the first detection value detected by the sensor 200 at the first position.

[0074] Step B12: Control the sensor 200 to move to the second position and obtain the second detection value detected by the sensor 200 at the second position.

[0075] Step B13: Calculate the difference between the first detection value and the second detection value, and use the difference as the detection compensation value.

[0076] Step B2: Maintain sensor 200 in the first position, and control display screen 700 to display the sum of detection compensation value and actual detection value detected by sensor 200 in the first position as detection result.

[0077] In scenarios requiring high detection accuracy, this solution eliminates the need for sensor 200 to be constantly in the second position, thus avoiding the problem of sensor 200 being in a second position far from the installation base and easily interfering with passing users.

[0078] The above embodiments of the present invention focus on describing the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0079] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
