Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0048] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] Pressure holding is a very common production process to strengthen the adhesion between two workpieces. For example, in the production process of the display industry, after pasting the glass and the middle shell, it is necessary to apply a specific pressure to them for a certain period of time to make the glass and the middle shell bond more tightly and ensure that the glass will not fall off during future use.

[0050] However, currently manual pressure maintenance cannot guarantee the uniformity of pressure, and fully automatic pressure maintenance is expensive and difficult to meet the needs of pressure maintenance operations.

[0051] Based on the above issues, see Figures 1 to 4 As shown, the present application provides a semi-automatic tire pressure maintaining fixture, including a frame 1, a wheel end pressure assembly, a power assembly 3, a control system 5 and an energy supply assembly 4, a groove is formed in the frame 1, an opening is provided on the frame 1, the groove is communicated with the opening, the wheel end pressure assembly includes at least one pressure wheel 2, the pressure wheel 2 includes a counterweight layer 21 and a contact layer 22, the counterweight layer 21 is rotatably arranged in the groove, the contact layer 22 is arranged on the counterweight layer 21, and is partially exposed outside the opening, the power assembly 3 is arranged on the frame 1, and is connected to the pressure wheel 2, the control system 5 is arranged on the frame 1, and is connected to the power assembly 3, for adjusting the rotation speed of the power assembly 3, the energy supply assembly 4 is arranged on the frame 1, and is connected to the control system 5, wherein a force applying portion 131 for a user to apply pressure is formed on the frame 1, and the force applying portion 131 is located above the pressure wheel 2.

[0052] Specifically, the present embodiment discloses a semi-automatic tire pressure-maintaining jig, including a frame 1, a wheel-end pressure assembly, a power assembly 3, a control system 5 and an energy supply assembly 4. In actual use, the frame 1 forms a force-applying portion 131, and is located above the pressure wheel 2. The user grasps the force-applying portion 131 on the frame 1 to bring the contact layer 22 of the pressure wheel 2 into contact with the glass. The counterweight layer 21 of the pressure wheel 2 can provide weight for glass pressure maintenance, and the contact layer 22 of the pressure wheel 2 can directly contact the glass to avoid damage to the glass during pressure maintenance. The power assembly 3 is connected to the pressure wheel 2 so that the power assembly 3 can drive the pressure wheel 2 to rotate. At the same time, the power assembly 3 is connected to the control system 5. The control system 5 can adjust the rotation speed of the power assembly 3 to achieve precise control of the power assembly 3 and ensure the uniformity of pressure, so that the rotation speed of the power assembly 3 can be controlled to meet the pressure maintenance process specification requirements. The structure is simple, the cost is low, and the use is flexible and convenient.

[0053] It should be noted that the user is responsible for the start, stop and direction of the device, and the control system 5 is used to adjust the speed of the power assembly 3 to achieve a semi-automatic effect.

[0054] See also Figure 1As shown, in this embodiment, a groove is formed in the frame 1, and an opening is also provided on the frame 1, the groove is connected to the opening, and the contact layer 22 of the pressure wheel 2 is partially exposed on the opening, so that the contact layer 22 of the pressure wheel 2 in the frame 1 can directly contact the glass, thereby achieving the pressure-maintaining effect of the pressure wheel 2.

[0055] In some embodiments, the control system 5 is used to adjust the rotation speed of the power assembly 3. The control system 5 is used to achieve precise adjustment of the rotation speed of the power assembly 3 to prevent the power assembly 3 from rotating too high or too low to affect the glass pressure maintenance effect.

[0056] In some embodiments, the energy supply component 4 is installed on the frame 1 and is used to connect with the control system 5. The energy supply component 4 can provide the required electrical energy for the control system 5 and the power component 3, ensuring that the use place of the device is not easily restricted and has a wider range of applications.

[0057] It should be noted that in order to adapt to more glass pressure-maintaining effects, the connection between the pressure wheel 2 and the frame 1 in the present device is set to be a detachable connection, that is, by replacing different pressure wheels 2 and using counterweight layers 21 of different weights, different glass pressure-maintaining effects can be achieved, thereby making the application range of the present device wider.

[0058] It can be understood that the counterweight layer 21 of different weights means that in a pressure wheel 2 of the same size, the volume ratio of the counterweight layer 21 and the contact layer 22 is different, so that the counterweight layer 21 produces different weights. For example, the volume ratio of the counterweight layer 21 and the contact layer 22 is 2:1, and the thickness of the contact layer 22 is greater than or equal to 5 mm. By limiting the size of the contact layer 22, the size of the pressure wheel 2 is limited, so that the pressure wheel 2 is small in size, and thus the device is small in size, which is convenient for users to hold and use.

[0059] For example, Figure 1 As shown, a rotating shaft 36 is installed in the frame 1, and nuts are provided at both ends of the rotating shaft 36. The rotating shaft 36 is fixed to the frame 1 by two nuts, and the pressure wheel 2 is rotatably installed on the rotating shaft 36. The user can disassemble the rotating shaft 36 and then disassemble the pressure wheel 2 on the rotating shaft 36, so that the pressure wheel 2 is easy to replace. By replacing the pressure wheel 2 with different specifications of the volume ratio of the counterweight layer 21 and the contact layer 22, the application range of the device is improved.

[0060] See also Figure 2 As shown, in another embodiment of the present application, a bearing 37 is provided on the rotating shaft 36 , and the bearing 37 is rotatably connected to the pressure wheel 2 .

[0061] Specifically, the rotating shaft 36 is fixed on the frame 1, and bearings 37 are installed at both ends of the rotating shaft 36. The two bearings 37 are rotatably connected to the pressure wheel 2, which is beneficial to reduce the friction between the pressure wheel 2 and the rotating shaft 36, improve the stability of the pressure wheel 2, and extend the service life of the pressure wheel 2. The structure is simple and easy to maintain.

[0062] See also Figure 2 and Figure 3 As shown, in another embodiment of the present application, the frame 1 includes an upper baffle 13, a front baffle 11 and a rear baffle 12, the top of the upper baffle 13 forms the force applying portion 131, the upper baffle 13 is provided with the power assembly 3, the front baffle 11 is provided on one side of the upper baffle 13, the control system 5 and the energy supply assembly 4 are provided on the front baffle 11, the rear baffle 12 is provided on the other side of the upper baffle 13, and is arranged opposite to the front baffle 11, wherein the groove is formed between the upper baffle 13, the front baffle 11 and the rear baffle 12, and the opening is formed on the side away from the upper baffle 13.

[0063] Specifically, the present embodiment discloses that the frame 1 includes an upper baffle 13, a front baffle 11 and a rear baffle 12, the top surface of the upper baffle 13 forms a force-applying portion 131, the force-applying portion 131 is for a user to grasp and apply pressure, the front end of the upper baffle 13 and the rear end of the upper baffle 13 are respectively installed with the front baffle 11 and the rear baffle 12, so that in the formed frame 1, the left side, the right side and the bottom are all hollowed out, so that a groove is formed in the shape enclosed by the upper baffle 13, the front baffle 11 and the rear baffle 12, an opening is formed at the bottom, and the left side of the frame 1 and the right side of the frame 1 also have openings; it can be understood that since the left side of the frame 1 and the right side of the frame 1 have openings, the frame 1 can install a larger pressure wheel 2, and the size of the pressure wheel 2 in the frame 1 is not easily limited. For example, the left side of the pressure wheel 2, the right side of the pressure wheel 2 and the bottom of the pressure wheel 2 can all be exposed outside the frame 1, thereby improving the applicable range of the size of the pressure wheel 2 on the frame 1.

[0064] In some embodiments, the shape of the upper baffle 13 can be circular, square or triangular, etc. For example, if the shape of the upper baffle 13 is circular, the corresponding shapes of the front baffle 11 and the rear baffle 12 are both arc-shaped; for example, if the shape of the upper baffle 13 is square, the corresponding shapes of the front baffle 11 and the rear baffle 12 are both square; in this embodiment, the shape of the upper baffle 13 is preferably square, and the shape of the front baffle 11 and the shape of the rear baffle 12 are also square, so that a U-shaped frame 1 can be formed, which can reduce the footprint of the device, is compact, easy to carry, convenient for users to use, and can make full use of the space of the device.

[0065] It is worth noting that since the top surface of the upper baffle 13 forms a force-applying portion 131, the thickness of the upper baffle 13 is 2-10 mm. In this embodiment, the thickness of the upper baffle 13 is preferably 5 mm, which avoids being too thick to increase costs and too thin to cause the upper baffle 13 to be insufficiently strong and easily damaged.

[0066] See also Figure 3 As shown, in another embodiment of the present application, a partition 14 is arranged between the front baffle 11 and the rear baffle 12, and the partition 14 divides the groove into a first space and a second space. The number of the pressure wheels 2 is two, and the two pressure wheels 2 are rotatably arranged in the first space and the second space respectively, and one of the pressure wheels 2 is connected to the power assembly 3.

[0067] Specifically, the present embodiment discloses that a partition 14 is arranged in the frame 1, and the partition 14 divides the groove in the frame 1 into a first space and a second space. The number of pressure wheels 2 is also set to two, and pressure wheels 2 are respectively arranged in the first space and the second space, and one of the pressure wheels 2 is connected to the power assembly 3; by arranging two pressure wheels 2, and one of the pressure wheels 2 is connected to the power assembly 3, the two pressure wheels 2 can maintain self-stability during the pressure maintaining process with the glass, thereby improving the pressure maintaining effect; it can be understood that since a single pressure wheel 2 makes it difficult for the device to maintain balance, therefore, by arranging two pressure wheels 2, the device can maintain balance and the use effect is better.

[0068] Preferably, the partition 14 is located in the middle of the frame 1, so that the size of the first space is the same as the size of the second space, which is conducive to installing two pressure wheels 2 of the same size on the frame 1 and improving installation convenience.

[0069] See also Figure 1 As shown, in another embodiment of the present application, a handle 6 is provided on a side of the upper baffle 13 facing away from the opening, and the handle 6 is staggered with the power assembly 3 .

[0070] Specifically, the present embodiment discloses a handle 6 installed on the top of the upper baffle 13, and the position of the handle 6 and the power assembly 3 are staggered to avoid affecting the use of the power assembly 3. At the same time, since the upper baffle 13 is a square baffle, a force-applying portion 131 is formed on the surface of the upper baffle 13. However, the user directly holds the upper baffle 13 to use the frame 1, which is not conducive to the user's hand grip. Therefore, by providing a handle 6 on the upper baffle 13, the user can hold the frame 1 by holding the handle 6, and the pressure wheel 2 in the frame 1 can be abutted against the glass, without holding the force-applying portion 131 of the frame 1, which makes the user's grip more convenient and improves the convenience of use.

[0071] In some embodiments, the handle 6 is in a U-shaped structure to facilitate the user's grip.

[0072] See also Figure 2 and Figure 3 As shown, in another embodiment of the present application, the power assembly 3 includes a power motor 31 and a transmission component. The power motor 31 is arranged on the frame 1 and is electrically connected to the control system 5. One end of the transmission component is arranged on the output shaft of the power motor 31, and the other end passes through the upper baffle 13 and is connected to the pressure wheel 2.

[0073] Specifically, the power motor 31 is installed on the upper baffle 13 and is located above one of the pressure wheels 2. It is electrically connected to the control system 5 through a wire, so that the control system 5 can adjust the power motor 31. At the same time, since the power motor 31 is directly located above the pressure wheel 2, the transmission component is used to directly connect the output shaft of the power motor 31 with the rotating shaft 36 where the pressure wheel 2 is located, which is beneficial to improving the transmission efficiency.

[0074] In some embodiments, slots are provided on the upper baffle 13 for installation of transmission components.

[0075] In some embodiments, a bracket 38 is disposed on the upper baffle 13 , and the power motor 31 is mounted on the bracket 38 , so as to facilitate fixing the power motor 31 on the upper baffle 13 .

[0076] Further, see Figure 2 and Figure 3 As shown, in another embodiment of the present application, the transmission component includes a first deceleration wheel 32, a second deceleration wheel 33 and a deceleration belt 34, the first deceleration wheel 32 is arranged on the output shaft of the power motor 31, the second deceleration wheel 33 is arranged on one of the pressure wheels 2, one end of the deceleration belt 34 is connected to the first deceleration wheel 32, and the other end passes through the upper baffle 13 and is connected to the second deceleration wheel 33.

[0077] Specifically, the transmission components disclosed in this embodiment include a first deceleration wheel 32, a second deceleration wheel 33 and a deceleration belt 34. The first deceleration wheel 32 is driven by the power motor 31, and the first deceleration wheel 32 drives the second deceleration wheel 33 through the deceleration belt 34. The second deceleration wheel 33 drives the pressure wheel 2 to rotate, which can not only change the output direction of the output shaft of the power motor 31, but also reduce the output power of the power motor 31, which is conducive to achieving deceleration and avoiding excessive rotation speed of the power motor 31.

[0078] In some embodiments, the first deceleration wheel 32, the second deceleration wheel 33 and the deceleration belt 34 can be replaced by synchronous wheels and synchronous belts, or by sprockets and chain belts. Users can select settings according to usage scenarios.

[0079] In some embodiments, one end of an output flange 35 is provided on the pressure wheel 2 , and the other end of the output flange 35 is connected to the second reduction wheel 33 .

[0080] Specifically, one end of the output flange 35 is fixed to the pressure wheel 2 by bolts, and the other end of the output flange 35 is sleeved on the rotating shaft 36. At the same time, the second deceleration wheel 33 is fixed on the output flange 35, so that the rotation of the second deceleration wheel 33 drives the output flange 35, and then drives the pressure wheel 2 on the output flange to rotate on the rotating shaft 36, thereby realizing the connection between the second deceleration wheel 33 and the pressure wheel 2.

[0081] See also Figure 4 As shown, in another embodiment of the present application, the energy supply component 4 includes a replaceable battery 41 and a power interface 42, the replaceable battery 41 is arranged on the frame 1 and is electrically connected to the control system 5, and the power interface 42 is electrically connected to the replaceable battery 41.

[0082] Specifically, a battery box is provided on the frame 1, and a replaceable battery 41 is installed in the battery box. The battery box is also provided with a power interface 42, which is connected to the replaceable battery 41 so that the replaceable battery 41 can be charged and used; the power interface 42 can be a USB interface or a triangular socket interface, etc., or it can be a combination of the two, such as a USB interface and a triangular socket interface, and the user can set it according to the usage scenario.

[0083] The replaceable battery 41 adopts a lithium battery pack, which can store more electrical energy than the transmission battery, has strong flexibility, and is safe and reliable.

[0084] In the above embodiment, the replaceable battery 41 adopts a lithium battery pack. In order to realize the replacement of the lithium battery pack, a quick connector is provided. The quick connector is also called a lithium battery quick connect plug or a lithium battery connector, such as XT30, XT60, etc. The quick connector is arranged in the battery box and is electrically connected to the lithium battery pack, so that the lithium battery pack can be easily and quickly replaced.

[0085] In another embodiment of the present application, the semi-automatic tire pressure maintaining jig further includes a button module 71, which is disposed on the frame 1 and connected to the control system 5, and the button module 71 is used to send control instructions to the control system 5 to control the power assembly 3.

[0086] Specifically, the button module 71 includes multiple buttons, each button corresponds to an input signal, and the input signal is sent to the control system 5 through the button. The control system 5 processes the input signal to control the power component 3 to perform a corresponding action, such as increasing the speed of the power component 3, reducing the speed of the power component 3, stopping the power component 3, and starting the power component 3.

[0087] In another embodiment of the present application, the semi-automatic tire pressure maintaining jig further includes a status indicator light 72 , and the status indicator light 72 is connected to the control system 5 .

[0088] Specifically, the status indicator light 72 includes a plurality of indicator lights for displaying the use status of the device, which is convenient for the user to identify. For example, the green indicator light is electrically connected to the control system 5, and the green indicator light indicates the operation status of the power assembly 3; another example is the red indicator light electrically connected to the control system 5, and the red indicator light indicates the fault status of the power assembly 3; another example is the power indicator light, which is electrically connected to the control system 5 and the energy supply assembly, and the power indicator light is used to display the power of the energy supply assembly.

[0089] In another embodiment of the present application, the control system 5 is a control panel, an integrated circuit board, a chip, or other electronic devices. The control system 5 controls the operation of the power assembly 3 to achieve an automatic control effect and save human and material resources. For example, the control system 5 is a microcontroller, and the microcontroller integrates a main control circuit module 51 and a drive circuit module 52. The microcontroller is preset with corresponding control software. The main control circuit module 51 is used to connect the replaceable battery 41, and the power interface 42 is connected to the replaceable battery 41 to realize the charging and discharging of the replaceable battery 41; the main control circuit module 51 is connected to the drive circuit module 52, and the drive circuit module 52 is connected to the power motor 31 to realize the control of the power motor 31; the status indicator light 72 and the button are connected to the main control circuit module 51. It is worth noting that the control software is loaded in the main control circuit module 51 to process specific application logic.

[0090] It can be understood that the drive circuit module 52 is determined according to the type of motor used. For example, if the power motor 31 is a DC motor, the drive circuit module 52 is an H-bridge driver, such as L298N, TB6612FNG, etc., and the connection method is a two-wire connection, that is, the positive and negative leads are directly connected to the output port of the drive circuit module 52, and then the voltage is adjusted by the PWM (pulse width modulation) signal to control the speed of the power motor 31, so that the speed of the power motor 31 can be effectively controlled by the drive circuit module 52; for example, if the power motor 31 is a stepping motor, the drive circuit is a driver, and the type The numbers are A4988, DRV8825, etc., and the connection method is a multi-wire connection, that is, each lead is connected to the corresponding input terminal of the driver, so that the speed of the power motor 31 can be effectively controlled through the drive circuit module 52; for example, the power motor 31 is a servo motor, and the drive circuit module 52 is a built-in driver. The connection method is a three-wire connection, namely, a power line, a signal line and a ground line. Since the drive circuit module 52 is a built-in driver, the servo circuit only needs to ensure normal operation; the user can choose the appropriate type of power motor 31 and the corresponding drive circuit module 52 according to the usage scenario.

[0093] S200, determining an execution action based on the input signal and generating a control instruction; wherein the execution action includes acceleration, deceleration, stop and start;

[0094] S300, sending the control instruction to a control system to generate a specified output power;

[0095] S400, inputting the designated output power into the power assembly to drive the pressure wheel to rotate.

[0096] Specifically, an input signal is obtained, and the input signal is provided by a user. The input signal can be implemented through keys, buttons, gestures, etc. For example, an input signal is sent to a control system through a key; an execution action is determined according to the input signal, and a control instruction is generated. The execution action includes acceleration, deceleration, stopping and starting. The execution action refers to accelerating, decelerating, stopping and starting the power component; and then the control instruction is sent to the control system to generate a specified output power. The specified output power refers to the output power of the power component. Power components of different powers have different rotational speeds. By inputting the specified output power, the power component drives the pressure wheel to rotate at a specified rotational speed. In this embodiment, the control method can effectively control the power component to ensure that it meets the pressure holding process requirements.

[0097] Exemplarily, each time the power of the power component is increased, it is quantitative and pre-set. Each time a quantitative power is added to the power component, the speed of the power component can be increased; each time the power of the power component is reduced, it is also quantitative and pre-set. Each time a quantitative power is reduced to the power component, the speed of the power component can be reduced; by setting a quantitative increase or decrease in power, the power component has multiple gears, and multi-gear switching is realized. By changing the power applied to the power component, the purpose of adjusting the speed of the power component is achieved.

[0098] In some embodiments, the user's input signal is obtained through buttons, and the number of buttons is set to four. The four buttons are all set on the frame. The four buttons are respectively a "+" button, a "-" button, a "Start" button, and a "Turn off" button. The "+" button is used to increase the speed of the power component, the "-" button is used to reduce the speed of the power component, the "Start" button is used to turn on the power component, and the "Turn off" button is used to turn off the power component.

[0099] In another embodiment of the present application, the control method further includes:

[0100] S500, real-time monitoring of the current operating status information of the power assembly, and providing the current operating status information to the user through a feedback mechanism, wherein the feedback mechanism includes any one or a combination of status indicator light and display screen feedback.

[0101] Specifically, the current operation status information includes normal operation information, stop operation information, abnormal operation information and rotation speed information. Normal operation information refers to the normal operation status of the power component, stop operation information refers to the stop operation status of the power component, abnormal operation information refers to the failure of the power component, and rotation speed information refers to the rotation speed of the power component. More specifically, by setting a voltage sensor on the power component, connecting the voltage sensor to the power component, and then connecting to the control system, real-time monitoring of the current operation status information of the power component can be achieved.

[0102] The present embodiment also discloses a feedback mechanism including any one or both of a status indicator light and a display screen, which can be set by the user according to the usage scenario. For example, a status indicator light and a display screen feedback combination is adopted. The status indicator light includes a plurality of indicator lights, and each operating status of a power component corresponds to an indicator light. At the same time, the display screen feeds back the current rotation speed of the power component. By setting the feedback mechanism, the user can quickly identify the device and use it conveniently.

[0103] In summary, the present invention provides a semi-automatic tire pressure-maintaining jig and a control method thereof, wherein a wheel-end pressure assembly is arranged on a frame, the wheel-end pressure assembly includes at least one pressure wheel, and the pressure wheel includes a counterweight layer and a contact layer, the counterweight layer is used to provide the main weight required for glass pressure maintenance, and the contact layer is used to contact the glass, and the user applies pressure on a force-applying portion on the frame to make the pressure wheel in the frame abut against the glass, and then the rotation speed of the power assembly is adjusted through a control system, so that the rotation speed of the power assembly is controllable to meet the pressure-maintaining process specification requirements, the structure is simple, the cost is low, and the use is flexible and convenient; by arranging a replaceable rotating shaft and pressure wheel, the device can also replace different pressure wheels to achieve different pressure-maintaining effects; the power motor and transmission components are arranged, which is conducive to reducing the rotation speed of the power motor and allowing the power motor to run smoothly.
