Description

Technical Field

[0001] This invention relates to the field of electronic device support structure technology, and in particular to a control method for a bracket and the bracket itself. Background Technology

[0002] To facilitate mounting on desktops, car dashboards, and other locations, existing brackets often feature suction cups. These suction cups are used to attach the brackets to devices such as mobile phones and tablets.

[0003] To ensure the stability of the phone after the suction cup holder is fixed, it can use sensors to detect the negative pressure value inside the suction cup cavity after the suction cup is attached. When the negative pressure value inside the suction cup is less than the preset value, the air pump is controlled to extract air, so that the pressure difference between the inside and outside of the suction cup is always maintained in a state where the suction cup can be stably attached to the attachment surface.

[0004] However, the preset values ​​of existing suction cup brackets are designed to ensure the stability of electronic devices mounted on the bracket. These preset values ​​are often quite large, which means that even a slight leak in the suction cup cavity is enough to reach the preset value, causing the air pump to start pumping air. This results in the air pump pumping air frequently, which greatly affects the user's actual experience and can easily reduce the lifespan of various components. Summary of the Invention

[0005] This invention provides a control method and a support for a bracket, in order to solve the technical problem of frequent air pumping in suction cup brackets with automatic air extraction function in the prior art.

[0006] This invention discloses a control method for a bracket, the bracket including a base, a suction cup, and an air extraction assembly. The suction cup is disposed on the base, and the air extraction assembly is connected to the cavity of the suction cup. A retaining member is disposed on the base for mounting electronic equipment. The bracket further includes a first detection component, a second detection component, and a control circuit. The control method includes: detecting the installation status of the electronic equipment on the retaining member using the first detection component and feeding the detection result back to the control circuit; detecting the air pressure parameter inside the cavity of the suction cup using the second detection component and feeding the detection result back to the control circuit; when the first detection component detects that an electronic equipment is mounted on the retaining member, and the control circuit determines that the negative pressure value inside the cavity of the suction cup is less than or equal to a first threshold based on the air pressure parameter, the control circuit controls the air extraction assembly to start; when the first detection component detects that no electronic equipment is mounted on the retaining member, and the control circuit determines that the negative pressure value inside the cavity of the suction cup is less than or equal to a second threshold based on the air pressure parameter, the control circuit controls the air extraction assembly to start; wherein the first threshold is greater than the second threshold.

[0011] Optionally, it also includes a third detection component, which is disposed on the base or the retaining member. The third detection component is used to detect the weight parameter of the electronic device and feed the detection result back to the control circuit. When the weight parameter is greater than or equal to a third threshold, the control circuit adjusts the first threshold parameter from a first value to a second value higher than the first value, wherein the third threshold is set between 220 grams and 260 grams.

[0012] Optionally, the system may also include a battery, which is electrically connected to the control circuit.

[0013] The present invention also discloses a bracket for implementing the bracket control method described above. The bracket includes a base, a suction cup, and an air extraction assembly. The suction cup is disposed on the base, and the air extraction assembly is connected to the cavity of the suction cup. A retaining member is disposed on the base for mounting electronic equipment.

The second detection component is used to detect the air pressure parameters inside the cavity of the suction cup. The control circuit receives the detection results from the first detection component and the second detection component, and controls the working state of the air extraction assembly according to the detection results.

[0014] Optionally, the base is provided with a pipeline communicating with the cavity of the suction cup, the second detection component is disposed in the base, and the second detection component is partially or entirely installed in the pipeline.

[0015] Optionally, the air extraction assembly is disposed within the base, and the air extraction assembly includes a vacuum pump and a motor connected to the control circuit, wherein the motor drives the vacuum pump to extract air from the cavity of the suction cup.

[0016] The beneficial effects of the bracket control method provided in this embodiment of the invention are as follows: the installation status of the electronic device holding the device is detected by the first detection component, and the air pressure parameters inside the suction cup cavity are detected by the second detection component. The control circuit controls the air extraction component to start under different conditions according to the detection results of the first and second detection components, thereby ensuring that the suction cup can be stably adsorbed on the adsorption surface while reducing the start frequency of the air extraction component.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] This invention provides a method for controlling a support, such as... Figure 1 and Figure 2As shown, the bracket includes a base 10, a suction cup 20, and an air extraction assembly 30. The suction cup 20 is disposed on the base 10, and the air extraction assembly 30 is connected to the cavity of the suction cup 20. A retaining member 40 is disposed on the base 10 for mounting electronic equipment. The bracket also includes a first detection component (not shown in the figure), a second detection component 11, and a control circuit 12. The control method of the bracket includes: detecting the installation status of the electronic equipment on the retaining member through the first detection component and feeding back the detection result to the control circuit 12; and detecting the air pressure parameter in the cavity of the suction cup 20 through the second detection component 11. The first detection component detects that the holding member 40 is equipped with electronic equipment, and the control circuit 12 determines that the negative pressure value in the cavity of the suction cup 20 is less than or equal to the first threshold based on the air pressure parameters. The control circuit 12 then controls the suction assembly 30 to start. When the first detection component detects that the holding member 40 is not equipped with electronic equipment, and the control circuit 12 determines that the negative pressure value in the cavity of the suction cup 20 is less than or equal to the second threshold based on the air pressure parameters, the control circuit 12 then controls the suction assembly 30 to start. The first threshold is greater than the second threshold.

[0021] The bracket control method provided in this embodiment of the invention controls the activation of the vacuum assembly 30 by detecting the installation status of electronic devices on the retaining member 40. When the first detection component detects that no electronic devices are installed on the retaining member 40, the bracket is adsorbed onto the adsorption surface (such as a desktop, car center console, etc.) by the suction cup 20. Even if the negative pressure value inside the cavity of the suction cup 20 is small, the suction cup 20 can still be adsorbed relatively stably on the adsorption surface due to the absence of the influence of the gravity of the electronic devices. Even if the negative pressure value inside the cavity of the suction cup 20 is less than or equal to the first threshold, the vacuum assembly 30 does not need to be activated. The vacuum assembly 30 is only activated when the negative pressure value inside the cavity of the suction cup 20 is less than or equal to the second threshold. The setting of the second threshold can be set according to the actual situation. It is only necessary to ensure that when no electronic devices are installed on the retaining member 40, the suction cup 20 can still be adsorbed relatively stably on the adsorption surface when the negative pressure value inside the cavity of the suction cup 20 is less than or equal to the second threshold. When the first detection component detects that an electronic device is installed on the holder 40, the electronic device's own gravity acts on the bracket, thus requiring a higher suction force on the suction cup 20 on the bracket. Therefore, when the negative pressure value in the cavity of the suction cup 20 is less than or equal to the first threshold, the air extraction component 30 needs to be activated to extract air to ensure that the suction cup 20 has sufficient suction force, thereby ensuring that the suction cup 20 can be stably adsorbed on the adsorption surface when the electronic device is installed on the holder 40. The first threshold is greater than the second threshold, meaning the negative pressure value inside the suction cup 20 corresponding to the first threshold is higher than the negative pressure value inside the suction cup 20 corresponding to the second threshold. A higher negative pressure value inside the suction cup 20 results in stronger suction. When no electronic equipment is installed on the holder 40, even if the second detection component 11 detects that the air pressure inside the suction cup 20 is less than or equal to the first threshold, the suction assembly 30 will not activate. The suction assembly 30 will only activate when there is a certain degree of air leakage in the suction cup 20, causing the negative pressure value inside the suction cup 20 to be less than or equal to the second threshold. This reduces the activation frequency of the suction assembly 30 during daily use. In this embodiment of the invention, the first detection component detects the installation status of electronic equipment on the holder 40, and the second detection component 11 detects the air pressure parameters inside the suction cup 20. The control circuit 12 controls the suction assembly 30 under different activation conditions, thereby ensuring that the suction cup 20 can stably adhere to the adsorption surface while reducing the activation frequency of the suction assembly 30.

[0022] The control method for the bracket provided in this embodiment of the invention refers to the negative pressure value inside the cavity of the suction cup 20 as the difference between the cavity of the suction cup 20 and the external atmospheric pressure. When the suction cup 20 is adsorbed onto the adsorption surface, the internal gas is squeezed out, thereby making the air pressure inside the cavity of the suction cup 20 lower than the external atmospheric pressure. Based on the principle of negative pressure, the suction cup 20 can be adsorbed onto the adsorption surface. The control circuit 12 can directly determine the magnitude of the negative pressure value inside the cavity of the suction cup 20 based on the air pressure parameter, for example, the air pressure parameter detected by the second detection component is directly a negative pressure value; the control circuit 12 can also indirectly determine the magnitude of the negative pressure value inside the cavity of the suction cup 20 based on the air pressure parameter, for example, the air pressure parameter detected by the second detection component is the actual air pressure value, then the control circuit 12 can calculate the negative pressure value based on the external atmospheric pressure and the actual air pressure value. In this case, to facilitate the calculation of the negative pressure value, a fixed external atmospheric pressure value, such as 101 kPa, can be used.

[0023] See Figure 1 and Figure 2 The present invention provides a method for controlling a stent, comprising: S201: The installation status of the holding electronic device is detected by the first detection component, and the detection result is fed back to the control circuit; S202: The second detection component detects the air pressure parameters inside the suction cup cavity and feeds the detection results back to the control circuit; S203: When the first detection component detects that the holding member is equipped with an electronic device, and the control circuit determines that the negative pressure value in the cavity of the suction cup is less than or equal to the first threshold based on the air pressure parameter, the control circuit controls the air extraction component to start. S204: When the first detection component detects that no electronic device is installed on the holding member, and the control circuit determines that the negative pressure value in the cavity of the suction cup is less than or equal to the second threshold based on the air pressure parameter, the control circuit controls the air extraction component to start.

[0024] In one embodiment, the first threshold is set between 30 kPa and 60 kPa. Therefore, when the first threshold is set to 30 kPa, meaning the control circuit 12 determines that the negative pressure inside the suction cup 20 is less than or equal to 30 kPa based on the air pressure parameters, and with electronic equipment installed on the retaining member 40, the control circuit 12 controls the suction assembly 30 to start. The suction assembly 30 extracts air from the cavity of the suction cup 20, thereby increasing the negative pressure inside the cavity of the suction cup 20 to ensure that the suction cup 20 has sufficient suction force to adhere to the suction surface. Similarly, when the first threshold is set to 60 kPa, meaning the negative pressure inside the cavity of the suction cup 20 is less than or equal to 60 kPa and electronic equipment is installed on the retaining member 40, the suction assembly 30 is activated. It should be understood that those skilled in the art can set the size of the first threshold according to actual conditions, thereby adjusting the size of the first threshold according to different usage scenarios or mobile phones of different weights to ensure that the suction force of the suction cup 20 can meet the actual usage scenario.

[0025] In one embodiment, the difference between the second threshold and the first threshold is greater than or equal to 10 kPa. The setting of the second threshold and the first threshold can be determined based on whether the suction cup 20 can be relatively stably adsorbed onto the adsorption surface when the holder 40 is used to mount electronic devices. Specifically, for example, when the first threshold is set at 60 kPa and the second threshold is set at 50 kPa, when the first detection component detects that an electronic device is installed on the holding member 40, if the negative pressure value in the cavity of the suction cup 20 is less than or equal to 60 kPa, the vacuum component 30 is activated to ensure that the negative pressure value in the cavity of the suction cup 20 remains at a relatively high value after the electronic device is installed on the holding member 40, thereby ensuring that the bracket can still be stably adsorbed on the adsorption surface by the suction cup 20. When the first detection component detects that no electronic device is installed on the holding member 40, the control circuit 12 determines that the negative pressure value in the cavity of the suction cup 20 is less than or equal to 60 kPa (i.e., the first threshold) and does not respond. Only when the negative pressure value in the cavity of the suction cup 20 is less than or equal to 50 kPa (i.e., the second threshold) is the vacuum component 30 activated to vacuum. Therefore, the number of times the vacuum component 30 vacuums can be reduced by the bracket control method provided in this embodiment. In one embodiment, the second threshold is greater than 15 kPa to ensure that the suction cup 20 can be stably adsorbed on the adsorption surface when the holder 40 is not equipped with electronic devices.

[0026] In one embodiment, the first detection component is one of a distance sensor, a magnetic sensor, an electromagnetic sensor, a light sensor, an infrared sensor, and a pressure sensor. Thus, when the first detection component is a distance sensor, if the first detection component does not detect an obstacle within a preset distance, it is determined that the electronic device is not installed; if the first detection component detects an obstacle within the preset distance and senses a change in the distance to the obstacle, it is determined that the installation status of the electronic device has changed. When the first detection component is a light sensor, if the first detection component detects that the light from the external environment is not blocked, it is determined that the electronic device is not installed; if the first detection component detects that the light from the external environment is blocked, it is determined that the electronic device is installed. In other embodiments, the first detection component may also be one of a magnetic sensor, an electromagnetic sensor, an infrared sensor, and a pressure sensor, as long as it can detect the installation status of the electronic device on the holder 40. The installation position of the first detection component can be determined according to actual needs, such as installing it on the holder 40 or on the base 10.

[0027] In one embodiment, the second detection component 11 is one of a pressure sensor, a vacuum pressure switch, or a negative pressure sensor. When the second detection component 11 is a pressure sensor, the pressure sensor detects the air pressure (i.e., air pressure parameter) inside the cavity of the suction cup 20 and feeds the detection result back to the control circuit 12. The control circuit 12 calculates the negative pressure value inside the cavity of the suction cup 20 based on the air pressure parameter and then determines whether the negative pressure inside the cavity of the suction cup 20 is less than or equal to a first threshold or a second threshold. When the second detection component 11 is a vacuum pressure switch, the vacuum switch is a switch that detects the vacuum range. When the vacuum level generated in actual operation reaches the specified requirements, the control circuit automatically opens and closes, sends an electrical signal, and instructs the vacuum adsorption mechanism to operate normally. Thus, when the second detection component 11 is a vacuum pressure switch, the control circuit 12 determines whether the negative pressure value inside the cavity of the suction cup 20 meets the conditions for starting the suction assembly based on the air pressure parameter fed back by the vacuum pressure switch. When the second detection component 11 is a negative pressure sensor, the negative pressure sensor detects the negative pressure value (i.e., air pressure parameter) inside the cavity of the suction cup 20 and feeds the detection result back to the control circuit 12. The control circuit 12 can directly determine whether the conditions for starting the suction assembly 30 are met based on the negative pressure value.

[0028] In one embodiment, the control method for the bracket provided by the present invention further includes a battery (not shown in the figure), which is electrically connected to the control circuit 12. By providing a battery, it is more convenient to power the various electronic components and circuits of the bracket, thereby realizing the corresponding functions. Simultaneously, the control method for the bracket provided by the present invention reduces the number of times the vacuum assembly 30 is activated, resulting in better battery life. It should be understood that, in embodiments where a battery is not provided, the bracket can be powered through a charging cable, solar panel, reverse power supply from a mobile phone, etc., to power its various electronic components and circuits.

[0029] In one embodiment, the control method for the bracket provided by the present invention further includes a third detection component (not shown in the figure). The third detection component is disposed on the base 10 or the retaining member 40. The third detection component is used to detect the weight parameter of the electronic device and feed the detection result back to the control circuit 12. When the weight parameter is greater than or equal to a third threshold, the control circuit 12 adjusts the first threshold parameter from a first value to a second value higher than the first value, wherein the third threshold is set between 220 grams and 260 grams. Thus, the third detection component detects the weight parameter of the electronic device. If the weight of the electronic device is detected to be heavy, by increasing the value of the first threshold, the bracket can adjust the size of the first threshold to meet the higher adsorption force requirements when a heavy mobile phone is installed on the retaining member. Specifically, when the third threshold is set to 220 grams, the third detection component detects that the weight parameter of the electronic device is greater than or equal to 220 grams. If the first threshold in the initial state is set to 30 kPa (i.e., the first value), then in order to keep the negative pressure value in the cavity of the suction cup 20 at a larger value, the first threshold needs to be increased. For example, the first threshold can be increased to 40 kPa (i.e., the second value) according to actual needs. This ensures that when the negative pressure value in the cavity of the suction cup 20 is less than or equal to 40 kPa and the holding member 40 is equipped with an electronic device, the suction component 30 is activated. This ensures that when a heavier electronic device is installed on the holding member 40, the size of the first threshold can be adjusted to meet the greater adsorption requirements of the heavier electronic device.

[0030] like Figures 1 to 4As shown, this embodiment of the invention also provides a bracket for implementing the bracket control method described above. The bracket includes a base 10, a suction cup 20, and an air extraction assembly 30. The suction cup 20 is disposed on the base 10, and the air extraction assembly 30 is connected to the cavity of the suction cup 20. A retaining member 40 is disposed on the base 10 for mounting electronic equipment. The bracket also includes a first detection component, a second detection component 11, and a control circuit 12. The first detection component is used to detect the installation status of the electronic equipment, the second detection component 11 is used to detect the air pressure parameters inside the cavity of the suction cup 20, and the control circuit 12 receives the detection results from the first detection component and the second detection component 11 and controls the working state of the air extraction assembly 30 according to the detection results. Therefore, the activation of the vacuum assembly 30 is determined by the detection results of the first and second detection components 11. This allows for reasonable control of the vacuum assembly 30's activation based on whether or not electronic equipment is installed on the retainer 40. When no electronic equipment is installed on the retainer 40, the bracket is not affected by the weight of the electronic equipment, so only a small suction force is needed to ensure the bracket is stably adhered to the suction surface by the suction cup 20. When electronic equipment is installed on the retainer 40, the bracket is affected by the weight of the electronic equipment, requiring a larger suction force from the suction cup 20 to ensure stability and prevent the electronic equipment and bracket from shifting or falling off the suction surface. Therefore, the detection results of the first and second detection components 11 ensure that the suction cup 20 is always stably adhered to the suction surface. Furthermore, the activation of the vacuum assembly 30 is controlled based on whether electronic equipment is installed on the retainer 40 and the air pressure within the suction cup 20, thus avoiding frequent activation of the vacuum assembly 30.

[0031] In one embodiment, such as Figures 2 to 4 The base 10 has a conduit 13 that communicates with the cavity of the suction cup 20. The second detection component 11 is disposed within the base 10, and is partially or entirely installed in the conduit 13. Thus, the second detection component 11 is disposed within the base 10 and communicates with the cavity of the suction cup 20 through the conduit 13. When the suction cup 20 is pressed and adsorbed onto the adsorption surface, it will not affect the detection result of the second detection component 11.

[0032] In one embodiment, such as Figures 2 to 4 The vacuum pump assembly 30 is disposed within the base 10. The vacuum pump assembly 30 includes a vacuum pump 31 and a motor 32 connected to the control circuit 12. The motor 32 drives the vacuum pump 31 to evacuate air from the cavity of the suction cup 20. As a result, the vacuum pump 31 evacuates air from the cavity of the suction cup 20, thereby increasing the negative pressure value inside the cavity of the suction cup 20, giving the suction cup 20 a greater adsorption force, and thus ensuring that the suction cup 20 can be stably adsorbed on the adsorption surface.

[0033] In one embodiment, such as Figures 2 to 4The retaining member 40 includes a support rod 41 and a retaining part 42. The two ends of the support rod 41 are rotatably connected to the retaining part 42 and the base 10, respectively. The base 10 is provided with a storage groove 14 for storing the support rod 41.

[0034] Specifically, the two ends of the support rod 41 are rotatably connected to the holding part 42 and the base 10, respectively. By adjusting the rotation angle of the support rod 41, the tilt angle and height of the holding part 42 can be changed to meet the user's usage needs from different viewing angles. The storage slot 14 on the base 10 can accommodate the rotated support rod 41 when the bracket is not in use, so that the support rod 41 and the base 10 form a close-fitting storage state, which greatly reduces the overall volume and thickness of the bracket, making it convenient for users to put the bracket into backpacks, pockets and other personal spaces, improving the portability of the product.

[0035] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
