Description

A mobile terminal

Technical Field

The present invention relates to the technical field of mobile terminal equipment, and in particular to a mobile terminal.

Background Art

With the development and popularization of smart mobile terminals, the appearance of mobile terminals is becoming more and more homogenized. At the same time, as consumers' requirements for mobile terminal performance and thinness are gradually increasing, the two restrict each other to some extent, making the traditional integrated mobile terminal design encounter a big bottleneck.

Summary of the invention

The present application provides a mobile terminal, which includes a host end, a slave end and a connecting mechanism. The host end is provided with a first battery, a processor and a first communication unit. The processor and the first communication unit are coupled to the first battery respectively. The first communication unit is used to communicate with an external device; the slave end is provided with a first display screen and a second battery. The first display screen is coupled to the second battery; the connecting mechanism is used to connect the host end and the slave end, and the slave end can be rotated relative to the host end through the connecting mechanism.

The mobile terminal provided in the present application includes a host processing part (host end) and a display control part (slave end), the host end is provided with a first battery, a processor and a first communication unit, the processor and the first communication unit are coupled and connected with the first battery respectively, the slave end is provided with a first display screen and a second battery, the first display screen is coupled and connected with the second battery, and the host end and the external device communicate through the communication connection between the first communication unit and the external device. Such a setting can realize the independent use of the slave end and the host end, the designs of the slave end and the host end do not affect each other, and the design avoids the homogenization of mobile terminal products. When designing the slave end, the number of devices on the slave end can be greatly reduced, so as to achieve a larger screen-to-body ratio, and then achieve the extreme lightness and thinness of the slave end. When designing the host end, the overall performance of the mobile terminal (such as battery capacity) is no longer limited by the appearance size. Splitting the mobile terminal into two relatively independent parts solves the problem that the mobile terminal product cannot be both light and thin and the battery capacity cannot be achieved at the same time.

The mobile terminal in this embodiment includes a host end 10, a slave end 20 and a connecting mechanism 30. The connecting mechanism 30 is arranged between the host end 10 and the slave end 20. The connecting mechanism 30 is used to connect the slave end 20 with the host end 10, and the connecting mechanism 30 can realize the rotation of the slave end 20 relative to the host end 10.

The slave end 20 can be connected to the host end 10 through a connecting mechanism 30 and can be rotated relative to the host end 10 to form an integral structure (see Figure 1); the slave end 20 and the host end 10 can also be used separately, that is, when using the mobile terminal, you can just hold this part of the slave end 20 and put the host end 10 in other positions, thereby achieving the purpose of using the slave end 20 and the host end 10 separately (see Figure 2).

Specifically, the host end 10 is provided with a first battery, a processor, and a first communication unit. The processor and the first communication unit are coupled to the first battery respectively, and the first battery supplies power to the processor, the first communication unit and other components.

The first battery can be in a detachable structure, so that the host end 10 can replace the energy source in time. The first battery can also be a battery with a small size, a long life, and does not need to be repeatedly charged and discharged. The first battery can also be a new type of battery that can be charged by light energy. The shape of the first battery can be square, round or other shapes, which are not specifically limited here. The charging form of the first battery of the host end 10 can be direct charging through an interface, and the charging form of the first battery of the host end 10 can also be wireless charging.

A first display screen and a second battery are provided in the slave end 20 . The first display screen is coupled to the second battery. The second battery is used to supply power to the first display screen and other components.

The second battery can be in a detachable structural form, which is convenient for timely replacement of the energy source from the machine end 20. The second battery can also be a battery with a small size, a long life, and does not require repeated charging and discharging. The second battery can also be a new type of battery that can be charged by light energy. The shape of the second battery can be square, circular or other shapes, which are not specifically limited here. The charging form of the second battery of the slave end 20 can be directly charged through the interface, or it can be charged through the host end 10. This part of the technical features will be described in detail later.

The first display screen may be a first display screen with a touch function. The first display screen may be a first display screen with a single-sided display. The first display screen may also be a transparent first display screen, which fully reflects the technological sense of the structure of the slave end 20.

The first communication unit is used to communicate with an external device, and the external device referred to in this embodiment includes a base station, a cloud server or other host end 10 or a terminal device, etc. The processor is used to process data. When the host end 10 and the slave end 20 are in a connected state, data can be updated and physically contacted for communication through a connection mechanism 30.

Optionally, the host end 10 is provided with a second communication unit, the second communication unit is coupled to the first battery, and the slave end 20 is provided with a third communication unit, the third communication unit is coupled to the second battery;

When the slave end 20 and the host end 10 are in a separated state, the third communication unit is connected to the second communication unit for communication, so as to realize communication between the slave end 20 and the host end 10;

When the slave end 20 and the host end 10 are in a connected state, the slave end 20 and the host end 10 can achieve communication connection with the second communication unit through the third communication unit; the slave end 20 and the host end 10 can also achieve physical contact communication connection through the connecting mechanism 30, at this time, the third communication unit and the second communication unit are in a disconnected state.

The third communication unit of the slave end 20 and the second communication unit of the host end 10 are any one of a Bluetooth communication unit, a WIFI communication unit, a ZigBee communication unit or an NFC communication unit. The short-range communication unit is used for near-field communication between the slave end 20 and the host end 10. The use scenarios include: home or office, etc. The host end 10 can be placed in a certain location. The user only needs to hold the slave end 20 to operate during use. The third communication unit and the second communication unit provide a near-field communication connection between the slave end 20 and the host end 10.

The first communication unit of the host end 10 is a remote communication unit. The first communication unit of the host end 10 is a main antenna to realize normal communication and network functions. The remote communication unit can be a cellular communication unit such as 2G\3G\4G\5G\6G, CDMA, etc., which is used for remote communication and transmission of data. The types of remote communication units are not listed here one by one.

The division of labor between the slave end 20 and the host end 10 is generally as follows: the slave end 20 is mainly used for display, TP control, and may also include imaging or other functions; while the host end 10 is used for calculation, storage, communication, energy storage imaging and other additional functions (such as audio output, external interface, etc.).

The mobile terminal provided in the embodiment of the present application includes a host processing part (host end 10) and a display control part (slave end 20), wherein the host end 10 is provided with a first battery, a processor, a first communication unit and a second communication unit, wherein the processor, the first communication unit and the second communication unit are coupled and connected to the first battery respectively, wherein the slave end 20 is provided with a first display screen, a second battery and a third communication unit, wherein the first display screen and the third communication unit are coupled and connected to the second battery respectively, wherein the host end 10 and the external device communicate with each other through the communication connection between the first communication unit and the external device, wherein the slave end 20 and the host end 10 can communicate with each other through the communication connection between the second communication unit and the third communication unit, or wherein the slave end 20 and the host end 10 can communicate with each other through the physical connection of the connection mechanism 30. Such a setting can realize the independent separation of the slave end 20 and the host end 10, wherein the designs of the slave end 20 and the host end 10 do not affect each other, and thus the homogenization of mobile terminal products is avoided in terms of design.

When designing the slave end 20, the number of components (camera modules) of the slave end 20 can be greatly reduced, thereby achieving a larger screen-to-body ratio, and then achieving the extreme lightness and thinness of the slave end 20. When designing the host end 10, the overall performance of the mobile terminal (such as battery capacity) is no longer limited by the appearance size. Splitting the mobile terminal into two relatively independent parts solves the problem that the mobile terminal product cannot be both light and thin and has a large battery capacity.

In addition, the slave end 20 can be rotated relative to the host end 10 through the connection mechanism 30, thereby enhancing the association between the slave end 20 and the host end 10.

Please refer to Figures 3 and 4. Figure 3 is a structural diagram of the host end 10 in Figure 1 of the present application, and Figure 4 is a structural diagram of the slave end 20 in Figure 1 of the present application.

Optionally, the host end 10 includes a first rear end surface 11 , a first front end surface 12 and a first side surface 13 .

The first rear end face 11 and the first front end face 12 are disposed back to back. It can be understood that the back to back arrangement specifically means that the first rear end face 11 and the first front end face 12 can be parallel or approximately parallel to each other, which is not limited here.

The first front end face 12 and the first rear end face 11 are connected by the first side face 13 to form a first accommodating cavity 14. The first accommodating cavity 14 is provided with a first battery, a processor, a first communication unit and a second communication unit. The first front end face 12 is provided with a through groove 15. The through groove 15 runs through the opposite ends of the first side face 13 to make the host end 10 present a U-shape.

The slave end 20 includes a second rear end face 21, a second front end face 22 and a second side face 23. The second rear end face 21 and the second front end face 22 are disposed opposite to each other and connected by the second side face 23 to form a second accommodating cavity 24. It can be understood that the opposite arrangement specifically means that the second rear end face 21 and the second front end face 22 can be parallel or approximately parallel to each other, which is not limited here.

The second accommodating cavity 24 is provided with a first display screen, a second battery and a third communication unit.

Optionally, the second rear end face 21 and the second front end face 22 are parallel or approximately parallel to each other, and the second side face 23 is perpendicular or approximately perpendicular to the second rear end face 21 and the second front end face 22 , respectively, so that the slave end 20 has a square structure.

It is worth noting that the U-shaped structure of the host end 10 and the square structure of the slave end 20 shown in Figures 3 and 4 are schematic diagrams of an overall outline. For example, when there are smooth transition surfaces on the host end 10 and the slave end 20, as long as the host end 10 is an overall U-shaped structure and the slave end 20 is an overall square structure, it is within the scope of protection of the present application.

Please refer to FIG. 5 , which is a schematic diagram of the three-dimensional structure of another embodiment of the mobile terminal of the present application in a connected state.

Specifically, part or all of the second front end surface 22 is used to display the information displayed on the first display screen. When the slave end 20 and the host end 10 are in a connected state, the slave end 20 can be rotated into the through slot 15, and the slave end 20 can also be rotated to the side of the host end 10 away from the through slot 15.

When the slave end 20 is accommodated in the through slot 15, the second front end face 22 can be set in a direction away from the bottom wall of the through slot 15, so that the user can normally view the information displayed on the first display screen when the slave end 20 is accommodated in the through slot 15; the second front end face 22 can also be set in the direction of the bottom wall of the through slot 15, so that the host end can protect the first display screen when the slave end 20 is accommodated in the through slot 15.

Optionally, the first accommodating cavity 14 may also be provided with a second display screen, and part or all of the bottom wall of the through groove 15 is used to display the information displayed on the second display screen. When the slave end 20 and the host end 10 are in a connected state, when the slave end 20 is rotated, the first display screen and the second display screen both display text or video information, and the text or video information may be related to each other or independent of each other.

Optionally, when the slave end 20 is accommodated in the through groove 15, the outer peripheral surface of the slave end 20 is aligned with the host end 10, that is, the second side surface 23 is aligned with the first side surface 13, and the second front end surface 22 or the second rear end surface 21 is aligned with the first front end surface 12. When the host end is U-shaped and the slave end is square, the slave end 20 and the host end 10 can be assembled to form a square-shaped whole.

Please refer to Figures 6 and 7. Figure 6 is a schematic cross-sectional view along the VI-VI direction in Figure 1 of the present application, and Figure 7 is a partially enlarged schematic view of the A area in Figure 6 of the present application.

The connecting mechanism 30 includes an elastic ejector pin 31. The elastic ejector pin 31 is provided on one of the side wall 16 of the through slot 15 and the second side surface 23. An ejector pin hole 32 matching the elastic ejector pin 31 is provided on the other of the side wall 16 of the through slot 15 and the second side surface 23. When the slave end 20 and the host end 10 are in a connected state, the elastic ejector pin 31 is elastically held in the ejector pin hole 32.

FIG6 shows a situation where an elastic ejector pin 31 is provided on the side wall 16 of the through groove 15 and an ejector pin hole 32 is provided on the second side surface 23. The working principle of the elastic ejector pin 31 will be explained in detail based on this in this embodiment. It can be understood that the situation where the elastic ejector pin 31 is provided on the second side surface 23 and the elastic ejector pin 31 is provided on the side wall 16 of the through groove 15 is similar to this and will not be described repeatedly.

There are two elastic ejector pins 31 , which are respectively disposed on two opposite side walls 16 of the through slot 15 .

The elastic ejector pin 31 may include a sealing shell 311 and an elastic component 312. The sealing shell 311 is connected to the side wall 16 of the through slot 15. The sealing shell 311 covers the elastic component 312 between the sealing shell 311 and the side wall 16 of the through slot 15. The elastic component 312 elastically extends out of the sealing shell 311 to be inserted into the ejector pin hole 32. The sealing shell 311 and the side wall 16 of the through slot 15 may be connected by a snap connection, a threaded connection, etc. In this embodiment, the sealing shell 311 and the side wall 16 of the through slot 15 are connected by a threaded connection.

The elastic component 312 includes a spring 313 and a telescopic head 314 connected to the spring 313 . The spring 313 supports the telescopic head 314 so that the telescopic head 314 can be extended and inserted into the ejector hole 32 .

Please refer to Figures 8 and 9. Figure 8 is a schematic cross-sectional view along the VIII-VIII direction in Figure 1 of the present application, and Figure 9 is a partially enlarged schematic view of the B area in Figure 8 of the present application.

The mobile terminal may further include a fixing mechanism 40 , which is used to work together with the connecting mechanism 30 to fix the slave end 20 on the host end 10 when the slave end 20 rotates into the through slot 15 .

The fixing mechanism 40 can be a protrusion 41 and a matching groove 42. One of the side walls 16 and the second side surface 23 of the through groove 15 is provided with a matching groove 42, and the other of the side walls 16 and the second side surface 23 of the through groove 15 is provided with a protrusion 41. The protrusion 41 and the matching groove 42 match each other.

Figures 8 and 9 show that the side wall 16 of the through slot 15 is provided with a protrusion 41, and the second side surface 23 is provided with a matching groove 42. This embodiment will use this as a basis to explain in detail the working principle of the matching between the protrusion 41 and the through slot 15. It can be understood that the situation in which the second side surface 23 is provided with the protrusion 41 and the side wall 16 of the through slot 15 is provided with the matching groove 42 is similar to this, and will not be repeated.

When the slave end 20 is fixed relative to the host end 10, the elastic ejector pin 31 is elastically held in the ejector pin hole 32 (see FIG. 7 ), and at the same time, the protrusion 41 is snapped into the matching groove 42 , so that the connecting mechanism 30 and the fixing mechanism 40 jointly fix the slave end 20 and the host end 10 together.

The specific process of assembling the slave end 20 and the host end 10 together by the cooperation of the protrusion 41, the matching groove 42, the elastic ejector pin 31 and the ejector pin hole 32 is as follows:

First, the second side surface 23 of the slave end 20 moves toward the side wall 16 of the through groove 15, and the elastic ejector pin 31 is held in the ejector pin hole 32. At this time, the elastic ejector pin 31 is in a state of being compressed by the slave end 20. Then, the slave end 20 rotates relative to the host end 10 until the convex portion 41 and the matching groove 42 are matched with each other, so that the slave end 20 is assembled to the host end 10. In the process of matching between the convex portion 41 and the matching groove 42, the elastic ejector pin 31 in the compressed state rebounds or is further compressed according to the specific matching conditions of the convex portion 41 and the matching groove 42, thereby eliminating the matching tolerance of the convex portion 41 and the matching groove 42.

The convex portion 41 may include a top wall 411 and a matching wall 412, wherein the matching wall 412 is connected to the first front end surface 12 or the side wall 16 of the through slot 15. In this embodiment, the matching wall 412 is connected to the side wall 16 of the through slot 15, and the matching wall 412 is arranged around the top wall 411. The top wall 411, the matching wall 412 and the side wall 16 of the through slot 15 are jointly arranged on the side wall 16 of the through slot 15 to protrude to form the convex portion 41.

Optionally, the angle between the mating wall 412 and the top wall 411 is an acute angle, that is, the protrusion 41 gradually shrinks from the top wall 411 to the first front end face 12 to form a locking space, and the mating groove 42 and the protrusion 41 cooperate with each other and are further clamped in the locking space, thereby increasing the mating strength between the protrusion 41 and the mating groove 42.

The angle between the mating wall 412 and the top wall 411 can also be any angle. The mating mechanism 40 further includes an elastic sleeve 43. The elastic sleeve 43 can be accommodated in the mating groove 42. The elastic sleeve 43 can also be sleeved on the protrusion 41. In this embodiment, the elastic sleeve 43 relies on its own elasticity to elastically shrink and sleeve on the protrusion 41.

The elastic sleeve 43 is arranged between the protrusion 41 and the matching groove 42. When the protrusion 41 and the matching groove 42 cooperate with each other, the elastic sleeve 43 is compressed between the two. This arrangement has two advantages: 1. The protrusion 41 and the matching groove 42 can be fixed together by interference fit; 2. The elastic sleeve 43 can prevent the slave end 20 from directly contacting the host end 10 when the protrusion 41 and the matching groove 42 cooperate with each other. The focus of the present application is that the slave end 20 and the host end 10 are separable and rotatable. That is to say, the slave end 20 and the host end 10 will often cooperate, separate and rotate during daily use. The elastic sleeve 43 can effectively ensure that the slave end 20 and the host end 10 are not damaged during the cooperation and separation process, thereby improving the service life of the slave end 20 and the host end 10. In addition, if the elastic sleeve 43 is damaged, it can also be conveniently disassembled and replaced, and the product life cycle is greatly improved.

The elastic sleeve 43 can be made of soft materials such as silicone or foam.

Please refer to FIG. 10 , which is a three-dimensional structural diagram of another embodiment of the mobile terminal of the present application in a connected state.

The fixing mechanism 40 can also be a buckle 44 and a locking groove 45. One of the side wall 16 of the through slot 15 and the second side surface 23 is provided with a buckle 44, and the other of the side wall 16 of the through slot 15 and the second side surface 23 is provided with a locking groove 45 matching the buckle 44. The elastic ejector pin 31 is held in the ejector pin hole 32, and the buckle 44 and the locking groove 45 are mutually engaged to achieve the fixing of the slave end 20 relative to the host end 10. FIG. 10 shows that the side wall 16 of the through slot 15 is provided with a buckle 44, and the second side surface 23 is provided with a locking groove 45 matching the buckle 44.

The second accommodating cavity 24 may not be provided with the camera module 25, but the first accommodating cavity 14 is provided with the camera module 25. When the slave end 20 needs to use the camera module 25 for taking photos or filming, the camera module 25 on the host end 10 is activated through the interaction between the third communication module and the second communication module, and then the slave end 20 calls the camera module 25 on the host end 10 to complete the tasks of taking photos or filming. In this way, the space in the second accommodating cavity 24 can be saved, and the slave end 20 can be made thinner and lighter.

The first accommodating cavity 14 and the second accommodating cavity 24 may also be provided with a camera module 25 for taking pictures or photographing.

Similarly, the second accommodating chamber 24 and the first accommodating chamber 14 can both be provided with buttons, and the button instructions of the slave end 20 can control the slave end 20, and the button instructions of the host end 10 can control the host end 10; of course, the second accommodating chamber 24 may not be provided with buttons, and the first accommodating chamber 14 may be provided with buttons, and the button instructions of the host end 10 can control the host end 10 and the slave end 20.

Optionally, when the slave end 20 and the host end 10 are in an assembled state or a rotated state, the host end 10 can charge the slave end 20 .

Specifically, when the slave end 20 and the host end 10 are in a rotating state, the host end 10 and the slave end 20 may be provided with contact terminals that cooperate with each other. The first battery and the second battery are electrically connected through the contact terminals between the elastic ejector pin 31 and the ejector pin hole 32 (see FIG. 7 ).

When the slave end 20 and the host end 10 are in an assembled state, the host end 10 and the slave end 20 may be provided with mutually matching contact terminals. The first battery and the second battery are electrically connected through the mutually matching contact terminals of the fixing mechanism 40, or the first battery and the second battery are electrically connected through the mutually matching contact terminals between the elastic ejector pin 31 and the ejector pin hole 32.

In addition, a space for charging the second battery of the slave end 20 can be designed on the host end 10. Two second batteries of the slave end 20 can be equipped on a daily basis, one of which is installed and used on the slave end 20, and the other can be charged on the host end 10. They can be used in rotation, thereby realizing the charging of the slave end 20 in the form of a physical connection between the host end 10 and the slave end 20.

In addition, the host end 10 can also charge the slave end 20 wirelessly, for example, the host end 10 is provided with a wireless charging transmitter, and the corresponding slave end 20 is provided with a wireless charging receiver, and when the slave end 20 and the host end 10 are close to or in contact, the host end 10 can charge the slave end 20 wirelessly, and optionally, the wireless charging method between the host end 10 and the slave end 20 can also be charging by WIFI, etc. The charging process of the host end 10 can be charging by connecting the charging cable to the socket.

Please refer to FIG. 11 , which is a three-dimensional structural diagram of another embodiment of the mobile terminal of the present application in a connected state.

The second accommodating cavity 24 may be provided with an electroacoustic device 26, which may be a microphone (the microphone may be divided into a main microphone and a secondary microphone), a speaker, a receiver, or the like for receiving or transmitting sound signals. The electroacoustic device 26 is responsible for inputting and outputting sound signals from the machine end 20, and a first sound hole 27 is provided on the machine end 20. The position of the first sound hole 27 matches the electroacoustic device 26, and the first sound hole 27 is used for the electroacoustic device 26 to output sound signals to the outside world or to pick up sound signals from the outside world.

The first sound hole 27 can be set on the second rear end face 21, the second front end face 22 or the second side face 23 of the slave end 20. However, considering that when the slave end 20 and the host end 10 are in the assembled state, the second rear end face 21 or the second side face 23 will be blocked by the host end 10, thereby affecting the normal sound output or sound input of the first sound hole 27, in the case where the host end 10 shares the electroacoustic device 26 of the slave end 20, the following will introduce in detail the solutions for these two cases.

When the first sound hole 27 is disposed on the second side surface 23:

A sound channel with a certain threshold value can be set between the second side surface 23 and the side wall 16 of the through groove 15, and the distance of the sound channel includes 0.5mm to 2mm, such as 0.5mm, 0.6mm, 0.8mm, 1.2mm, 1.8mm or 2mm. The first sound hole 27 ensures that the electroacoustic device 26 normally outputs or inputs sound when the slave end 20 and the host end 10 are in the assembled state through the sound channel, so that the host end 10 can share the electroacoustic device 26 of the slave end 20 when the slave end 20 and the host end 10 are in the assembled state.

A second sound hole 17 matching the position of the first sound hole 27 may also be provided on the host end 10, the second sound hole 17 is provided on the side wall 16 of the through groove 15, the first front end face 12 or the first side face 13 is provided with a third sound hole 18, the third sound hole 18 and the second sound hole 17 are mutually connected from the inside of the host end 10, and the sound emitted by the electroacoustic device 26 is transmitted or transmitted from the first sound hole 27, the second sound hole 17 and the third sound hole 18 in sequence when the slave end 20 and the host end 10 are in the assembled state, thereby ensuring that the electroacoustic device 26 can also normally output or input sound when the slave end 20 and the host end 10 are in the assembled state, and then the host end 10 can share the electroacoustic device 26 of the slave end 20 when the slave end 20 and the host end 10 are in the assembled state. FIG. 11 shows the situation where the third sound hole 18 is provided on the first side face 13.

Please refer to FIG. 12 , which is a three-dimensional structural diagram of another embodiment of the mobile terminal of the present application in a connected state.

The slave end 20 can also be provided with a first sound hole 27 at the connection between the second side surface 23 and the second front end surface 22 on one side of the side wall 16 close to the through groove 15, and the electro-acoustic device outputs or inputs sound from the first sound hole 27, thereby ensuring that the electro-acoustic device 26 can also output or input sound normally when the slave end 20 and the host end 10 are in an assembled state, and further, when the slave end 20 and the host end 10 are in an assembled state, the host end 10 can share the electro-acoustic device 26 of the slave end 20.

Please refer to FIG. 13 , which is a three-dimensional structural diagram of another embodiment of the mobile terminal of the present application in a connected state.

When the first sound hole 27 is arranged on the second rear end surface 21, a second sound hole 17 matching the position of the first sound hole 27 is arranged on the host end 10, the second sound hole 17 is arranged on the bottom wall of the through groove 15, and a third sound hole 18 is arranged on the first rear end surface 11 or the first side surface 13. The second sound hole 17 and the third sound hole 18 are mutually connected from the inside of the host end 10, and the sound emitted by the electro-acoustic device is transmitted into or out of the first sound hole 27, the second sound hole 17 and the third sound hole 18 in turn, thereby ensuring that the electro-acoustic device 26 can also normally emit sound or input sound when the slave end 20 and the host end 10 are in an assembled state, and then the host end 10 can share the electro-acoustic device 26 of the slave end 20 when the slave end 20 and the host end 10 are in an assembled state.

Please refer to FIG. 14 , which is a three-dimensional structural diagram of another embodiment of the mobile terminal of the present application in a separated state.
