[0002] With the advancement of science and technology and the development of the communication field, mobile phones, tablet computers and other terminal devices are becoming increasingly popular.

[0050] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0051] The embodiment of the present disclosure provides a middle frame assembly, Figure 1 is an exploded schematic diagram of a middle frame assembly provided in an embodiment of the present disclosure, referring to Figure 1 As shown, the middle frame assembly may include a middle frame body 1 , an antenna base 2 and a metal rotating part 3 .

[0052] The following is an introduction to the various components of the middle frame assembly:

[0053] 1. Middle frame body 1

[0054] The middle frame body 1 can be used to accommodate relevant components of the terminal device. The present disclosure does not specifically limit the material of the middle frame body 1, and can be matched and set according to factors such as the usage scenarios and manufacturing costs of different terminal devices. For example, the middle frame body 1 can be made of one or more materials such as metal, alloy, and plastic.

[0055] An opening 11 is formed on the outer side wall of the middle frame body 1 . The opening 11 is used to accommodate the antenna base 2 . The shape and size of the opening 11 are adapted to the antenna base 2 .

[0056] The present disclosure does not specifically limit the number of openings 11, and can be set according to the number of antenna bases 2 required by different terminal devices. For example, a frame of the middle frame body 1 can have one or more openings 11; for another example, multiple frames of the middle frame body 1 each have one or more openings 11.

[0057] 2. Antenna base 2

[0058] The antenna base 2 is located in the opening 11 and connected to the middle frame body 1 .

[0059] The present disclosure does not make any specific limitation on the connection relationship between the antenna base 2 and the middle frame body 1. A detachable connection method such as threaded fastening connection and snap connection can be adopted, or a non-detachable connection method such as glue dispensing and welding can be adopted. The specific connection relationship can be matched and set according to factors such as the material of the antenna base 2 and the middle frame body 1, the usage scenario of the terminal device, and the connection strength of different terminal devices to the antenna base 2 and the middle frame body 1.

[0060] The antenna base 2 is an insulator base, such as plastic (polyethylene PE, polypropylene PP, polyvinyl chloride PVC, etc.), ceramics, rubber, glass, etc., which can be selected based on the mechanical strength of the terminal device and the manufacturing cost of the antenna base 2. The insulator antenna base 2 can reduce the shielding and blocking of the antenna signal generated by the oscillation coupling between the metal rotating part 3 and the circuit board 7, improve the strength of the antenna signal, and improve the use effect of the metal rotating part 3.

[0061] 2.1. Accommodation slot 21

[0062] The antenna base 2 may have a receiving groove 21, the receiving groove 21 faces the outside of the middle frame body 1, and the receiving groove 21 is used to receive the metal rotating part 3. The present disclosure does not specifically limit the shape, size, groove depth and other factors of the receiving groove 21, and can be matched and set according to the shape, size and other factors of the metal rotating part 3.

[0063] The side wall of the receiving groove 21 has a first through hole 21a, and the first through hole 21a is used to receive the second elastic member 51 of the blocking member 5. The present disclosure does not specifically limit the number of the first through holes 21a, and can be matched and set according to the number of blocking members 5 in different middle frame assemblies. The present disclosure does not specifically limit the position of the first through hole 21a, and can be matched and set according to the relative position of the second elastic member 51 in the blocking member 5 and the receiving groove 21.

[0064] The bottom of the receiving groove 21 has a second through hole 21b, and the second through hole 21b is used to accommodate the trigger part 62 of the bouncing mechanism 6. The present disclosure does not specifically limit the number of the second through holes 21b, and can be matched and set according to the number of bouncing mechanisms 6 in different middle frame assemblies. The present disclosure does not specifically limit the position of the second through hole 21b, and can be matched and set according to the relative position of the trigger part 62 of the bouncing mechanism 6 and the receiving groove 21.

[0065] 2.2. Third side wall 22

[0066] Reference Figure 5 As shown, Figure 5 It is a structural schematic diagram of a middle frame assembly provided by an embodiment of the present disclosure, wherein the third side wall 22 of the antenna base 2 is flush with the outer side wall of the middle frame body 1, wherein the third side wall 22 is the side wall where the notch of the receiving groove 21 is located. The third side wall 22 is flush with the outer side wall of the middle frame body 1. On the one hand, it is convenient for assemblers to assemble the middle frame assembly and improve production efficiency. At the same time, the flush design is beneficial to the structural stability of the terminal device, reduces the possibility of mechanical damage caused by uneven edges, and improves the durability of the terminal device. On the other hand, the transition of the flush structure is smoother, giving users a sense of overall balance, improving the aesthetics of the terminal device, and can also improve the comfort of holding the terminal device and improve the user's experience.

[0067] 3.Metal rotating parts 3

[0068] The metal rotating member 3 is at least partially located in the receiving groove 21 and is hinged to the antenna base 2 . The metal rotating member 3 can rotate relative to the antenna base 2 at a preset angle.

[0069] When the metal rotating part 3 rotates to the first position relative to the antenna base 2, the metal rotating part 3 is located in the accommodating groove 21. At this time, the metal rotating part 3 is in a non-working state. The clearance environment between the metal rotating part 3 and the circuit board 7 is poor, but the metal rotating part 3 is located in the accommodating groove 21 and does not need to occupy additional space. The overall volume of the terminal device is small, which is suitable for scenarios where users carry and move the terminal device.

[0070] When the metal rotating part 3 rotates to the second position relative to the antenna base 2, the metal rotating part 3 is partially located outside the accommodating groove 21. At this time, the metal rotating part 3 is suitable for working state. The clearance environment between the metal rotating part 3 and the circuit board 7 is good. The antenna signal generated by the oscillation coupling between the metal rotating part 3 and the circuit board 7 is located in a relatively open environment. The antenna signal quality of the terminal device is good, which is conducive to users in places with poor antenna signals such as elevators and remote mountainous areas to achieve good communication.

[0071] 3.1. First side wall 31

[0072] The first side wall 31 of the metal rotating part 3 can have a groove 31a. The first side wall 31 is a side wall of the metal rotating part 3 that is perpendicular to the bottom of the accommodating groove 21. The groove 31a can be snap-fitted with the blocking part 5 to prevent the metal rotating part 3 from rotating from the first position to the second position under the action of the first elastic part 4, so as to ensure that the metal rotating part 3 will not pop out of the accommodating groove 21 when the user does not apply external force to the metal rotating part 3, thereby avoiding harm to the user or external force causing the popped-up metal rotating part 3 to be deformed or cracked, and other adverse phenomena.

[0073] 3.2. Second side wall 32

[0074] The metal rotating part 3 has a second side wall 32, which is opposite to the bottom of the accommodating groove 21. The second side wall 32 is also opposite to the trigger part 62 located in the second through hole 21b. When a user applies a pressing force to the metal rotating part 3, the pressing force can be transmitted to the trigger part 62 through the second side wall 32. The trigger part 62 is squeezed and will change its height in the accommodating groove 21 under the action of elastic force or other forms of force.

[0075] 3.3. Fourth side wall 33

[0076] When the metal rotating member 3 rotates to the first position relative to the antenna base 2, Figure 5As shown, the fourth side wall 33 of the metal rotating member 3 is flush with the third side wall 22 of the antenna base 2, wherein the fourth side wall 33 is the side wall of the metal rotating member 3 away from the bottom of the receiving groove 21. The fourth side wall 33 of the metal rotating member 3 is flush with the third side wall 22 of the antenna base 2. On the one hand, it is helpful to prevent foreign objects (such as sand, water drops, etc.) from being located at the place where there is a height difference between the fourth side wall 33 and the third side wall 22, thereby causing the foreign objects to enter the interior of the middle frame assembly through the second through hole 21b and other gaps at the bottom of the receiving groove 21 during the process of the metal rotating member 3 rotating relative to the antenna base 2 to rotate to the second position, causing damage to other components of the terminal device, which is beneficial to improving the service life of the terminal device. At the same time, the flush design is beneficial to the structural stability of the middle frame assembly, reducing the possibility of mechanical damage caused by the height difference between the fourth side wall 33 and the third side wall 22, and improving the durability of the terminal device; on the other hand, the transition of the flush structure is smoother, giving users a sense of overall balance, improving the aesthetics of the terminal device, and can also improve the comfort of holding the terminal device and improve the user's experience.

[0077] 4. First elastic member 4

[0078] The middle frame assembly may further include a first elastic member 4, referring to Figure 2 As shown, Figure 2 It is an exploded schematic diagram of another middle frame assembly provided in an embodiment of the present disclosure. The first elastic member 4 is respectively connected to the antenna base 2 and the metal rotating member 3. When the metal rotating member 3 is in the first position, the first elastic member 4 is in a compressed state, and the first elastic member 4 applies an elastic force to the metal rotating member 3 toward the second position.

[0079] The present disclosure does not make any specific limitation on the connection relationship between the first elastic member 4 and the antenna base 2 and the metal rotating member 3 respectively. A detachable connection method such as a threaded fastening connection and a snap connection may be adopted, or a non-detachable connection method such as gluing and welding may be adopted. The specific setting may be matched according to factors such as the size and shape of the antenna base 2 and the metal rotating member 3, and the connection strength of the terminal device to the connection.

[0080] When the metal rotating member 3 is located at the second position, the first elastic member 4 may be in a natural state. At this time, the first elastic member 4 does not apply elastic force to the metal rotating member 3 .

[0081] When the metal rotating part 3 is in the second position, the first elastic part 4 can be in a compressed state. At this time, the first elastic part 4 applies an elastic force to the metal rotating part 3 in the opposite direction from the second position to the first position, and the metal rotating part 3 abuts against the side wall of the accommodating groove 21. The supporting force of the side wall of the accommodating groove 21 on the metal rotating part 3 is greater than the elastic force of the first elastic part 4, and the metal rotating part 3 no longer rotates relative to the antenna base 2.

[0082] 5. Stopper 5

[0083] The middle frame assembly may further include a blocking member 5, which is connected to the antenna base 2. When the metal rotating member 3 is in the first position, the blocking member 5 applies a resistance to the metal rotating member 3 that is opposite to the elastic force and greater than the elastic force. At this time, since the resistance of the blocking member 5 is greater than the elastic force of the first elastic member 4, the metal rotating member 3 will not rotate relative to the antenna base 2 and exceed the accommodating slot 21 when the user does not apply external force to the metal rotating member 3. This can prevent the metal rotating member 3 protruding from the accommodating slot 21 from causing harm to the user or external force (for example: when the terminal device is put into a pocket, the friction of the pocket on the metal rotating member 3) causing the metal rotating member 3 protruding from the accommodating slot 21 to deform or crack, or other adverse phenomena.

[0084] Reference Figure 2 As shown, the blocking member 5 may include a second elastic member 51 and a ball 52, wherein the second elastic member 51 is located in the first through hole 21a and connected to the antenna base 2, and the ball 52 is connected to the second elastic member 51. When the metal rotating member 3 is located at the first position, the ball 52 is partially embedded in the groove 31a of the first side wall 31 of the metal rotating member 3, and the ball 52 cooperates with the groove 31a to provide resistance to the metal rotating member 3, and the resistance is opposite to the elastic force of the first elastic member 4 and is greater than the elastic force, thereby limiting the metal rotating member 3 at the first position.

[0085] When the metal rotating member 3 is located at the second position, the ball bearings 52 have been separated from the grooves 31 a . At this time, the ball bearings 52 do not exert any resistance on the metal rotating member 3 .

[0086] 6. Bounce mechanism 6

[0087] The middle frame assembly may further include a bouncing mechanism 6, which may include a mechanism body 61 and a triggering portion 62. The mechanism body 61 is connected to the middle frame body 1, and the triggering portion 62 is connected to the mechanism body 61 and is located in the second through hole 21b.

[0088] The present disclosure does not make any specific limitation on the connection relationship between the mechanism body 61 and the middle frame body 1. A detachable connection method such as a threaded fastening connection and a snap connection may be adopted, or a non-detachable connection method such as gluing and welding may be adopted. The specific connection relationship may be matched and set according to factors such as the volume shape of the mechanism body 61 and the connection strength of different terminal devices to the mechanism body 61 and the middle frame body 1.

[0089] The bouncing mechanism 6 has a first state and a second state, and the mechanism body 61 can drive the trigger part 62 to move between preset height positions. The present disclosure does not specifically limit the driving method of the mechanism body 61 on the trigger part 62. For example, the mechanism body 61 can drive the trigger part 62 through multiple connecting rods and elastic members, and the mechanism body 61 can also drive the trigger part 62 through a motor. The present disclosure embodiment takes the example of the mechanism body 61 driving the trigger part 62 through multiple connecting rods and elastic members, and other similar situations are not repeated.

[0090] 6.1. First state

[0091] Reference Figure 3 As shown, Figure 3 It is a cross-sectional schematic diagram of a middle frame assembly provided by an embodiment of the present disclosure. When the bouncing mechanism 6 is in the first state, the height S1 of the trigger portion 62 protruding from the bottom of the accommodating groove 21 is less than or equal to the distance L between the second side wall 32 and the bottom of the accommodating groove 21 when the metal rotating part 3 is in the first position. At this time, the trigger portion 62 has no contact with the metal rotating part 3, and the trigger portion 62 does not apply any elastic force to the metal rotating part 3.

[0092] When the bouncing mechanism 6 is in the first state, if the trigger part 62 is squeezed, the bouncing mechanism 6 switches to the second state. In the second state, the height S2 of the trigger part 62 protruding from the bottom of the accommodating groove 21 is greater than the distance L between the second side wall 32 and the bottom of the accommodating groove 21 when the metal rotating part 3 is in the first position. In the process of switching the trigger part 62 from the first state to the second state, the trigger part 62 contacts the metal rotating part 3 and applies a reverse force to the metal rotating part 3. The reverse force applied by the trigger part 62 to the metal rotating part 3 is in the same direction as the elastic force applied by the first elastic part to the metal rotating part 3, and the reverse force applied by the trigger part 62 to the metal rotating part 3 is greater than the elastic force applied by the first elastic part to the metal rotating part 3, which is greater than the resistance applied by the ball 52 and the groove 31a to the metal rotating part 3. The metal rotating part 3 can rotate from the first position to the second position.

[0093] 6.2. Second State

[0094] Reference Figure 4 As shown, Figure 4 It is a cross-sectional schematic diagram of another middle frame assembly provided in an embodiment of the present disclosure. When the bouncing mechanism 6 is in the second state, the height S2 of the trigger portion 62 protruding from the bottom of the accommodating groove 21 is greater than the distance L between the second side wall 32 and the bottom of the accommodating groove 21 when the metal rotating part 3 is in the first position.

[0095] When the bounce mechanism 6 is in the second state, if the trigger part 62 is squeezed, the bounce mechanism 6 switches to the first state, and the user presses the metal rotating part 3 located in the second position, and the metal rotating part 3 contacts the trigger part 62 in the second state and transmits the pressing force to the trigger part 62. The user continues to press the metal rotating part 3, and the metal rotating part 3 rotates to the first position, and the trigger part 62 switches from the second state to the first state.

[0096] Based on the same concept, an embodiment of the present disclosure further provides a terminal device, which may include a middle frame assembly as described in any one of the above embodiments.

[0097] The terminal devices involved in the present disclosure may also be referred to as terminals, mobile terminals, electronic devices, user equipment (UE), etc. Exemplarily, the terminal device may be a smart phone, a tablet computer, a laptop computer, a wearable device (e.g., a smart watch), etc., or it may be a professional shooting device such as a digital camera, a SLR camera / micro-single camera, a gimbal camera, a sports camera, a drone, etc. It should be understood that the present disclosure does not specifically limit the specific technology and specific device form adopted by the terminal device. In the description of the above embodiments, a mobile phone is taken as an example for description, but the present disclosure is not limited to this.

[0098] Reference Figure 6 As shown, Figure 6 It is a partial schematic diagram of a terminal device provided by an embodiment of the present disclosure. The terminal device may further include a circuit board 7 and a conductive element 8. The circuit board 7 is connected to the middle frame body 1; the conductive element 8 is electrically connected to the circuit board 7 and the metal rotating part 3 respectively.

[0099] The present disclosure does not specifically limit the components of the circuit board 7, and can be matched and set according to the components required by the metal rotating part 3 to realize its own different functions, such as: power amplifier (PA), low noise amplifier (LNA), filter (Filter), switching element, etc.

[0100] It is understandable that the terminal device provided by the embodiment of the present disclosure includes a hardware structure and / or software module corresponding to each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0101] The conductive element 8 is a spring connector. On the one hand, the spring connector (Pogo pin) is designed with elastic material, which can ensure the electrical connection between the metal rotating part 3 and the circuit board 7 during the rotation of the metal rotating part 3, so as to ensure good electrical contact at the connection, thereby ensuring stable and reliable signal transmission and reducing the risk of failure of the metal rotating part 3 caused by poor contact; on the other hand, the spring connector is made of wear-resistant material, has a long service life, is not easily affected by deformation such as compression and extension, can be reused many times, thereby increasing the service life of the terminal equipment and reducing replacement and maintenance costs. At the same time, the spring connector is small in size and simple in structure, and can effectively utilize the internal space of the middle frame assembly, which is conducive to the pursuit of compact and lightweight design of terminal equipment.

[0102] The working process of the terminal device is as follows:

[0103] First, the metal rotating part 3 is in the first position. At this time, the third side wall 22 of the antenna base 2 is flush with the outer wall of the middle frame body 1, and the fourth side wall 33 of the metal rotating part 3 is flush with the third side wall 22 of the antenna base 2. The metal rotating part 3 is located in the accommodating groove 21 and does not need to occupy additional space. The overall volume of the terminal device is small, which is suitable for scenarios such as users carrying and moving the terminal device.
