The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present invention and the above figures are used to distinguish similar objects without being used for Describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

The technical solution of the present invention can be applied to various types of devices, wherein the first device and the second device can be the same type of device, such as two housings, or different types of devices, for example, the first device is a display. The second device is a back cover, and the type of the device is not limited herein.

1 is a schematic structural view of an assembly system of a device according to an embodiment of the present invention, which includes a first device 100 and a second device 200 to be assembled, and a first control component 300 and a second control component 400.

Wherein, the first device 100 and/or the second device 200 form a cavity capable of accommodating a gas and a channel formed with a connecting cavity and an external environment after the first device 100 and the second device 200 are bonded together. .

In the embodiment of the present invention, the first control component may be a control component for implementing any one of the following three functions, and specifically includes:

The first type: the first control component 300 is configured to allow airflow from the cavity to flow through the channel to the second control component 400 when the air pressure of the external environment is less than the air pressure in the cavity, and is used for the air pressure in the external environment to be larger than the cavity The air pressure is not allowed to flow from the external environment to the cavity via the passage;

Correspondingly, the second control component 400 connected to the channel is configured to reduce the air pressure in the cavity, and is configured to prompt to disconnect the second control component from the channel when detecting that the air pressure in the cavity decreases to a preset value . It can be seen that when the first control unit 300 has the first function described above, the second control unit 400 is not required to transmit another control signal to trigger the first control unit 300 to control the airflow direction.

For example, the first control member may include a slider 300a that is matched with the passage seal, and the cross-sectional area of the slider increases sequentially from the cavity toward the passage direction. Correspondingly, the second control member may include a gas generating device, the gas generating device Used to create a low pressure gas stream to reduce the gas pressure in the cavity. 1a is a cross-sectional view showing the structure of an assembly system of a device according to an embodiment of the present invention. The following is an analysis of the process in which the slider 300a implements the first function described above: when the second control member 400 connected to the passage generates a low-pressure airflow, the slider 300a can be in the low-pressure airflow and the cavity generated by the second control member 400. The pressure difference between the high pressure air flows is moved to move away from the cavity to open the passage to allow airflow from the cavity to flow through the passage to the second control member 400, when the air pressure in the cavity is lowered to a preset value and When the second control component 400 is disconnected from the passage, the slider 300a can move toward the cavity under the action of the atmospheric pressure to close the passage, and the airflow is not allowed to flow from the external environment to the cavity via the passage, that is, the above structure The slider 300a can realize the control of the airflow direction by controlling the opening and closing of the channel, and during the opening and closing of the control channel, the second control component 400 is not required to transmit another control signal, only by the second control component itself. The function and the external atmospheric pressure can automatically control the opening and closing of the channel.

For another example, the first control component may include a one-way valve, and correspondingly, the second control component may include a gas generating device or an air extracting device, wherein the gas generating device is configured to generate a low-pressure airflow to reduce air pressure in the cavity, An air extraction device is used to extract gas from the cavity to reduce the air pressure within the cavity. In the actual application process, the air inlet of the one-way valve is disposed on the side close to the cavity, and the air outlet is disposed on the side away from the cavity, the one-way valve can realize the first function, the field The principle of the one-way valve can be known by the skilled person according to the prior art, and details are not described herein again.

It should be noted that only the two examples illustrate the specific structure that can implement the first function described above. In practical applications, other structures that can implement this function can also be used, and the specific structures are not listed here. Lift.

Second: the first control component 300 is configured to close the channel when the trigger signal is received;

Correspondingly, the second control component 400 connected to the channel is configured to reduce the air pressure in the cavity, and is further configured to send a trigger signal to the first control component 300 when detecting that the air pressure in the cavity decreases to a preset value, To close the channel. Therefore, when the first control component 300 has the second function, it is necessary to send a trigger signal to the first control component 300 by using the second control component 400, so as to prevent the airflow from passing through the channel to the air through the closed channel. The cavity flow, i.e., the first control component 300, requires the second control component 400 to transmit additional control signals during the closing of the control channel.

For example, the first control component may include a threaded valve 300b ₁ and a control button 300b ₂ disposed on the first device and/or the second device, the control button 300b _{2 being} configured to detect a decrease in air pressure within the cavity to a preset When the value is received, the trigger signal is received, and the valve flap of the threaded valve 300b ₁ is pressed according to the trigger signal to close the threaded valve 300b ₁ ; correspondingly, the second control component may include a gas generating device or an air extracting device, wherein The gas generating device is for generating a low pressure gas stream to reduce the gas pressure in the cavity, and the gas extracting device is for extracting gas in the cavity to reduce the gas pressure in the cavity. The following is a description of the second control unit as a gas generating device. Referring to FIG. 1b, FIG. 1b is a cross-sectional view showing another embodiment of the device assembly system according to the embodiment of the present invention. In the actual application, the initial state of the threaded valve 300b ₁ is an open state, so that when the second control member 400 connected to the passage generates a low-pressure airflow, the airflow is allowed to flow from the cavity to the second control member 400 via the passage, when the cavity When the internal air pressure is lowered to a preset value, the control button 300b ₂ receives the trigger signal from the second control unit 400 and drives the threaded valve 300b _{1 to} close, so as to prevent the air flow from flowing from the external environment to the cavity via the passage.

It should be noted that the specific structure that can implement the foregoing second function is described by way of example only. In practical applications, other structures that can implement this function may also be used, which are not enumerated here.

a third type: the first control unit 300 is configured to open a channel when receiving the first signal, and to close the channel when receiving the second signal;

Correspondingly, the second control component 400 is configured to generate a low-pressure airflow after transmitting the first signal to the first control component 300 to reduce the air pressure in the cavity, and when detecting that the air pressure in the cavity is lowered to a preset value, A second signal is sent to the first control component 300 to close the channel. Therefore, when the first control unit 300 has the third function described above, it is necessary to move to the first control unit via the second control unit 400. The member 300 transmits a first signal to enable flow of air from the cavity to the second control component 400 via the passage and a second signal to the first control component 300 to prevent flow of air from the ambient to the cavity via the passage That is, the first control component 300 requires the second control component 400 to transmit an additional control signal during the opening and closing of the control channel. For example, the second control component 400 can include a gas generating device for generating a low pressure gas stream to reduce the gas pressure in the cavity, or an air extracting device for extracting gas in the cavity to reduce Air pressure in the low cavity.

In this embodiment, the first control component 300 may be disposed in the channel or may be disposed on the outer interface of the channel. Specifically, the specific position of the first control component is not limited herein, as long as the channel can be matched with the channel to implement the corresponding The function is OK.

In the actual application process, the gas generating device is first connected to the channel, at this time, the two sides of the channel are divided It is not a cavity and a gas generating device, that is, after the gas generating device is connected to the channel, the external environment in which the cavity directly contacts the channel is a gas generating device; and then the gas generating device is turned on to generate a low-pressure airflow due to the gas pressure of the gas generating device. Less than the air pressure in the cavity, and the first control component allows the airflow to flow from the cavity to the second control component via the passage when the air pressure in the external environment (ie, the gas generating device at this time) is less than the air pressure in the cavity, thus The high pressure gas stream within the cavity flows from the cavity to the gas generating device via the passage, thereby reducing the gas pressure within the cavity.

When the first control component is a one-way valve, the second control component may include a gas generating device or an air extracting device, and the step 303 specifically includes: generating a low-pressure airflow by using a second control component connected to the channel to reduce the cavity in the cavity.

The control member flows, in one case, the function imparted by the structure of the first control member itself, such as the one-way valve described in the embodiment shown in Fig. 1; and the other case is generated by the self-structure and the second control member a low pressure gas stream, such as the slider described in the embodiment of Figure 1, which is driven away from the cavity by a pressure differential between the low pressure gas stream produced by the second control member and the high pressure gas stream in the cavity. The direction is moved to open the passage to allow airflow from the cavity to flow through the passage to the second control member.

304. When detecting that the air pressure in the cavity decreases to a preset value, disconnecting the second control component from the channel;

In this embodiment, when it is detected that the air pressure in the cavity is lowered to a preset value, the second control component is disconnected from the channel, and at this time, the external environment directly contacted by the cavity through the channel is a normal living environment. Here, the normal living environment pressure is defined as external atmospheric pressure, such as standard atmospheric pressure. Since the air pressure of the first control component in the external environment (defined as the external atmospheric pressure) is greater than the air pressure in the cavity, the airflow is not allowed to flow from the external environment to the cavity via the passage, and the air pressure in the cavity is smaller than the external atmospheric pressure, the first device With the second device, the assembly of the two can be achieved by using a pressure difference.

It should be noted that, in this embodiment, the first control component can realize that when the air pressure of the external environment is greater than the air pressure in the cavity, the airflow is not allowed to flow from the external environment to the cavity via the channel. In one case, the first The function imparted by the structure of the control unit itself, such as the one-way valve described in the embodiment shown in Fig. 1; and the other case, by means of its own structure and external atmospheric pressure, such as the description in the embodiment shown in Fig. 1.

Therefore, compared with the prior art, the embodiment of the invention is environmentally friendly, simple in process and does not affect the appearance of the product, and can be widely adapted to the assembly between the screen and the back cover of the ultra-thin/borderless/screwless/environmental mobile phone or the wearable device in the future. .

For the sake of understanding, the method for assembling the device in the embodiment shown in FIG. 3 is described in detail in a specific application scenario. For details, refer to FIG. 3a. In this application scenario:

The first device is a mobile phone panel 100', and the second device is a mobile phone backplane 200'; the first control component is a slider 300a' that is matched with the channel seal, and the cross-sectional area of the slider 300a' is sequentially from the cavity to the channel. Increased; the second control component is a gas generating device 400'.

First, the mobile phone panel 100' and/or the mobile phone backplane 200' are processed to form a gas-filled cavity 600' and form a communication between the mobile phone panel 100' and the mobile phone backplane 200'. The passage 700' of the cavity and the external environment. For example, the processing of the handset panel 100' and/or the second device described above may be such that a recess is formed in both the handset panel 100' and the handset backplane 200'.

Then, the slider 300a' is set, at which time the slider 300a' can be inserted into the channel 700' to seal the slider 300a' with the channel 700'.

In this application scenario, the mobile phone panel 100' and the mobile phone backplane 200' need to use the pressure difference to achieve the assembly of the two, which is equivalent to requiring a force acting on the assembled mobile phone panel 100' or the mobile phone backplane 200'. It is not possible to separate the mobile phone panel 100' from the mobile phone backplane 200', assuming that the force is 100 Newton, according to the projected area of the cavity 600' on the plane of the mobile phone panel 100' or the mobile phone backplane 200', to determine how much the air pressure in the cavity is reduced (the air pressure in the cavity is a preset value). The low-pressure airflow generated by the gas generating device 400' can be stopped and the gas generating device 400' can be disconnected from the channel, including:

Force, as assumed in the application scenario of 100 Newtons, S refers to the projected area of the cavity 600' on the plane of the mobile phone panel 100' or the mobile phone backplane 200'.

In this application scenario, assuming S is 25 square centimeters (5 cm x 5 cm rectangle), you can get the default value = 101325 - 100 / 0.0025 = 101325-40000 = 61325 N / m2, which is the default value ≈

0.6pa, which is equivalent to disconnecting the gas generating device 400' from the channel when the air pressure in the cavity is detected to be reduced to 0.6pa. At this time, the mobile phone panel 100' and the mobile phone backboard 200' are 100 Newtons. The force is pressed together to achieve stable assembly between the mobile phone panel 100' and the mobile phone backplane 200'.

Wherein, the gas generating device 400' may further include a gas pressure detecting module G1 for detecting whether the gas pressure in the cavity is lowered to a preset value, thereby generating gas before the gas generating device 400' is disconnected from the channel The device 400' is in communication with the cavity via the passage, corresponding to the gas pressure in the gas generating device, the passage and the cavity, so that the air pressure in the cavity can be detected by the air pressure detecting module provided in the gas generating device 400'.
