The body of the traditional middle frame is of an integrated structure, has an antenna function and can receive and transmit signals. By adopting the electronic equipment with the middle frame, once the outer edge of the equipment is subjected to large force due to falling, collision and the like, internal devices and screens of the equipment are easy to damage and even break, and the use of a user is influenced.

SUMMERY OF THE UTILITY MODEL

An embodiment of the application provides a middle frame of an electronic device. The middle frame can reduce the probability and degree of damage of internal devices and screens of the electronic equipment due to external force, so that the market competitiveness of the electronic equipment can be improved.

In a first aspect, the middle frame includes a body and an elastic conductive member, the body includes an antenna portion disposed at an outer edge thereof and a main body portion disposed at an inner side of the antenna portion, the antenna portion and the main body portion are separately disposed, an inner side surface of the antenna portion and an outer side surface of the main body portion are spaced from each other, and the antenna portion and the main body portion are connected through the elastic conductive member.

Design like this, when electronic equipment outward flange atress, power can transmit antenna portion earlier on, because antenna portion and main part components of a whole that can function independently set up and formed the interval space between the medial surface of antenna portion and the lateral surface of main part, so antenna portion atress back can inwards move, thereby it takes place elastic deformation to absorb partial impact energy to support and press the electrically conductive piece of elasticity, impact energy has been less when making power further transmit on the inside device of equipment and the screen through the main part, so can reduce the probability and the degree that inside device of electronic equipment and screen damaged because of external force, consequently, electronic equipment's market competition can be promoted. Meanwhile, the current of the antenna part can flow back to the main body part through the elastic conductive part and then flow back to the cathode of the electronic equipment through the main body part, so that the antenna part can realize the antenna function.

In a first implementation manner of the first aspect, based on the first aspect, the antenna portion is disposed at an outer edge corner of the body, and the elastic conductive member is connected to the antenna portion.

The antenna part is arranged at the outer edge corner of the body, so that the layout of internal devices of the equipment is reasonable, and signals of the antenna part arranged at the outer edge corner are not easily influenced because the outer edge corner of the equipment is not usually held when the electronic equipment is held (if the electronic equipment is required to be held); in addition, if the outer edge corner is impacted firstly when the electronic equipment falls, the possibility of damaging the internal device and the screen of the electronic equipment is higher because the contact surface at the outer edge corner is small and the impact strength is higher, so that the probability and the degree of damaging the internal device and the screen of the electronic equipment due to external force can be reduced to a greater extent by arranging the antenna part and the elastic conductive piece at the outer edge corner of the body.

In a second embodiment of the first aspect, based on the first aspect or the first embodiment of the first aspect, the elastic conductive member is bent in a sheet structure or is in a spiral structure. The sheet structure is adopted, the occupied arrangement space is small, the electronic equipment is favorably thinned, the through-current capacity of the sheet structure is better, and the circuit stability is favorably realized.

By the design, when the electronic equipment is subjected to external force, the deformation degree of the transition part is large, so that the energy absorption effect can be fully achieved, and the deformation degrees of the outer connecting part and the inner connecting part are small, so that the reliability of electric connection between the main body part and the antenna part can be guaranteed.

In an embodiment of the third aspect, based on the third aspect, a contact surface between the external connection portion and the antenna portion and a contact surface between the internal connection portion and the main body portion are both parallel to the screen mounting surface of the middle frame. Because the force that the outward flange of electronic equipment received is mainly the lateral force that is roughly parallel to the screen installation face of center, consequently design like this, outer connecting portion and interior connecting portion are difficult to break away from with antenna portion and main part when can ensure the outward flange atress of electronic equipment to can guarantee the electric connection reliability better.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram of an embodiment of an electronic device according to the present disclosure; fig. 2 is a schematic exploded view of fig. 1. The electronic apparatus mainly includes a middle frame 100, a screen 200, internal devices, and the like. The electronic equipment can be a mobile phone, a tablet computer, a handheld computer, an interphone, a POS machine, a vehicle traveling recorder, a wearable device, a virtual reality device, a vehicle-mounted front-mounted device and other terminal products with screens.

The screen 200 may be a flexible screen or a rigid screen, and the type of the screen is not limited herein. The middle frame 100 is a mounting base for a screen and internal devices (such as a battery, a circuit board and the like) and is a main bearing member of electronic equipment. The screen 200 is fixedly installed on the screen installation surface of the middle frame 100. The screen 200 and the middle frame 100 may be adhered and fixed (an adhesive layer 300 may be formed in a product) by an adhesive medium (such as glue, a back glue, etc.), or may be connected and fixed by a fastener, where the fixing connection manner of the screen 200 and the middle frame 100 is not limited. The outer edge of the electronic device may be provided with a corner, in fig. 1 the part inside the dashed circle is a corner. Of course, the outer edges of the electronic device may also be provided without corners.

Referring to fig. 3, 4 and 5, fig. 3 is a schematic view of a corner region of fig. 1; FIG. 4 is a schematic view of the center body inside the dotted circle in FIG. 3; figure 5 is a cross-sectional view of the first embodiment of the middle frame at position a-a (see figure 3). The middle frame 100 mainly includes a body 101, an elastic conductive member 102, and a covering body 103.

The body 101 includes an antenna portion 1011 disposed at an outer edge thereof and a main body portion 1012 located inside the antenna portion 1011. The material of the body 101 may be aluminum, copper, magnesium alloy, aluminum alloy, copper alloy, or other metal material with good conductivity.

The elastic conductive member 102 connects the antenna portion 1011 and the main body portion 1012. Specifically, the elastic conductive member 102 includes an outer connecting portion 1021, an inner connecting portion 1022, and a transition portion 1023. The external connection portion 1021 is connected to the antenna portion 1011. The inner connecting portion 1022 is connected to the main body portion 1012. The transition portion 1023 is connected between the outer connecting portion 1021 and the inner connecting portion 1022. The elastic conductive member 102 may be of an integral structure or a split structure. The elastic conductive member 102 may be made of metal or other material with better conductive capability.

The cladding body 103 is clad on the surface of the body 101, and can be specifically molded on the surface of the body 101 in an injection molding mode, and the cladding body 103 can be made of plastic and other materials which are easy to be injection molded. The covering body 103 plays a role in cushioning, protecting the body 101 and shaping different appearance effects. The elastic conductive member 102 may be completely covered by the covering body 103, or may be partially or completely exposed outside the covering body 103.

At least a part of the antenna part 1011 of the body 101 is exposed outside the cover 103, i.e. at least a part of the antenna part 1011 is not covered by the cover 103. The main body 1012 of the main body 101 is connected to a negative electrode of the electronic device. The current of the antenna portion 1011 flows back to the negative electrode through the main body portion 1012, thereby realizing the functions of receiving and transmitting signals. As shown in fig. 4, the antenna portion 1011 and the main body portion 1012 are provided separately, that is, the antenna portion 1011 and the main body portion 1012 are two independent parts. The inner side surface of the antenna portion 1011 and the outer side surface of the main body portion 1012 are not in contact with each other and are spaced apart from each other, and a space is formed therebetween.

The cover 103 connects the main body portion 1012 and the antenna portion 1011 of the main body 101, and specifically, the portion of the cover 103 covering the main body portion 1012 and the portion of the cover 103 covering the antenna portion 1011 are connected together by another portion of the cover 103, so that the main body portion 1012 and the antenna portion 1011 are connected together. By the design, the integrity of the middle frame is good, and the integral strength of the middle frame is guaranteed to meet the force bearing requirement.

As shown in fig. 5, the cover 103 is provided with a relief groove C, and at least a part of the relief groove C is located between the outer side surface of the main body 1012 and the inner side surface of the antenna 1011.

In order to implement the antenna function, the body 101 of the conventional middle frame may have an integrated structure, and it can be understood that the antenna portion and the main body portion of the body 101 of the conventional middle frame are integrally disposed, so that the current of the antenna portion can flow back through the main body portion, thereby implementing the antenna function. Adopt the electronic equipment of this kind of center, in case because of falling, collide with etc. when leading to the electronic equipment outward flange to receive great power, power can transmit on electronic equipment's the inside device and the screen through the integral type body, and the unable absorption impact energy of integral type body leads to power to transmit on electronic equipment's the inside device and the screen on the time impact energy great, consequently, lead to electronic equipment's inside device and screen damage even cracked easily, influence the user and use.

And this application, when electronic equipment outward flange received great power, power can transmit antenna portion 1011 earlier on, because antenna portion 1011 sets up with main part 1012 components of a whole that can function independently and antenna portion 1011's medial surface and main part 1012's lateral surface between formed the interval space, so antenna portion 1011 can inwards move after the atress, thereby it takes place elastic deformation to support and press elastic conductive piece 102 and absorb some impact energy, impact energy has been less when making power further transmit on the inside device of equipment and on screen 200 through main part 1012, so can reduce the probability and the degree that inside device of electronic equipment and screen damaged because of external force, consequently can promote electronic equipment's market competition. Meanwhile, the current of the antenna part 1011 can flow back to the main body part 1012 through the elastic conductive member 102, and then flow back to the negative electrode of the electronic device through the main body part 1012, so that the antenna part 1011 can realize the antenna function.

If the space between the outer side of the main body 1012 and the inner side of the antenna 1011 is completely filled with the cover 103, and the antenna 1011 has substantially no displacement space, when the outer edge of the electronic device is stressed, the distance that the antenna 1011 moves inwards is very limited, and the antenna cannot well press the elastic conductive member 102 to deform and absorb energy, so that the energy absorption effect of the elastic conductive member 102 is affected. Through setting up the stress relief groove C, let at least a part of stress relief groove C be located between the medial surface of the lateral surface of main part 1012 and antenna portion 1011, reserved the displacement space for antenna portion 1011 like this for antenna portion 1011 can fully inwards move when the outward flange atress of electronic equipment and support and press elastic conductive piece 102 and warp the energy-absorbing, thereby can ensure elastic conductive piece 102's energy-absorbing effect.

In short, the energy absorption capacity of the middle frame is improved on the basis of not influencing the antenna function of the middle frame, so that the probability and the degree of damage to internal devices and a screen of the electronic equipment due to external force are reduced, and the market competitiveness of the electronic equipment is improved.

Specifically, for the body 101 with a corner at the outer edge, the antenna portion 1011 may be disposed at the corner at the outer edge of the body 101 and connected to the elastic conductive member 102. If the outer edge of the body 101 has a plurality of corners, the antenna portion 1011 may be disposed at one or more or all of the corners and connected to the elastic conductive member 102. Of course, the antenna portion 1011 may be disposed on other areas (e.g. a flat area) of the outer edge of the body 101 and connected to the elastic conductive member 102.

Set up antenna portion 1011 at the outward flange corner of body 101, do benefit to the overall arrangement rationalization of the inside device of electronic equipment, because the outward flange corner that can not hold electronic equipment usually when handheld electronic equipment (if need handheld), so set up antenna portion 1011 at outward flange corner, the signal of antenna portion 1011 is difficult to receive the influence. In addition, if the outer edge corner is firstly stressed when the electronic device is dropped, the impact strength is higher due to the small contact surface at the outer edge corner, so that the possibility of damaging the internal devices and the screen 200 of the electronic device is higher, and therefore, the probability and the degree of damaging the internal devices and the screen 200 of the electronic device due to external force can be greatly reduced by arranging the antenna part 1011 at the outer edge corner of the body 101 and connecting the elastic conductive member 102.

Specifically, the transition portion 1023 of the elastic conductive member 102 may have an elastic deformation capability higher than that of the outer connecting portion 1021 and also higher than that of the inner connecting portion 1022. That is, when the same external force is applied, the deformation degree of the transition portion 1023 is greater than the deformation degree of the outer connecting portion 1021 and greater than the deformation degree of the inner connecting portion 1022. With such a design, when the electronic device is subjected to an external force, the transition portion 1023 has a large deformation degree, so that the energy absorption function can be sufficiently performed, and the deformation degrees of the external connection portion 1021 and the internal connection portion 1022 are small, so that the reliability of the electrical connection with the main body portion 1012 and the antenna portion 1011 can be ensured. Specifically, different elastic deformation capacities can be achieved by setting the transition portion 1023, the outer connecting portion 1021 and the inner connecting portion 1022 to different shapes, and different elastic deformation capacities can be achieved by setting the transition portion 1023, the outer connecting portion 1021 and the inner connecting portion 1022 to different materials.

Specifically, the external connection portion 1021 and the antenna portion 1011, and the internal connection portion 1022 and the main body portion 1012 may be in surface contact, point contact, or line contact, or may be indirectly connected through an intermediate member without contact. With the surface contact, the external connection part 1021 and the internal connection part 1022 can be reliably supported by the main body part 1012 and the antenna part 1011, and thus are less likely to be deformed, and thus the electrical connection reliability can be better secured.

Specifically, when the external connection part 1021 and the antenna part 1011 and the internal connection part 1022 and the main body part 1012 are in surface contact, the contact surface between the external connection part 1021 and the antenna part 1011 and the contact surface between the internal connection part 1022 and the main body part 1012 may be parallel to the screen mounting surface of the middle frame 100, or may not be parallel to the screen mounting surface. Because the force applied to the outer edge of the electronic device is mainly a lateral force approximately parallel to the screen mounting surface of the middle frame 100, the parallel design can ensure that the outer connecting part 1021 and the inner connecting part 1022 are not easily separated from the antenna part 1011 and the main body part 1012 when the outer edge of the electronic device is applied with force, thereby better ensuring the reliability of electrical connection.

Specifically, the external connection portion 1021 may be connected to the top surface of the antenna portion 1011 (see fig. 5, 6, and 10), or may be connected to the inner surface of the antenna portion 1011 (see fig. 7, 8, and 9). The inner connecting portion 1022 may be connected to the top surface of the main body portion 1012 (see fig. 5, 6, and 10), or may be connected to the outer side surface of the antenna portion 1011 (see fig. 7, 8, and 9). The transition portion 1023 may be located at least partially inside the space between the inner side surface of the antenna portion 1011 and the outer side surface of the main body portion 1012 (see fig. 6, 7, 8, and 9), or may be located outside the space (see fig. 10).

When the external connection portion 1021 is connected to the inner side surface of the antenna portion 1011 and the internal connection portion 1022 is connected to the outer side surface of the main body portion 1012, a boss B (as shown in fig. 7) or a groove a (as shown in fig. 8) may be disposed on the inner side surface of the antenna portion 1011 and the outer side surface of the main body portion 1012, so that the boss B or the groove a forms a mounting surface parallel to the screen mounting surface of the middle frame 100, and the external connection portion 1021 and the internal connection portion 1022 are connected to the mounting surface.

Specifically, the external connection portion 1021 and the antenna portion 1011 may be fixedly connected, the internal connection portion 1022 and the main body portion 1012 may be fixedly connected, and the relative positions of the two fixedly connected to each other are fixed, so that the fixed connection can ensure the reliability of the electrical connection. The fixing connection may be welding, riveting, bolting, clipping, conductive adhesive bonding, etc., and the fixing connection between the inner connection part 1022 and the main body part 1012 and the fixing connection between the outer connection part 1021 and the antenna part 1011 are not limited herein.

Specifically, the elastic conductive member 102 may have a bent plate structure. The thickness dimension of the sheet structure is much smaller than its width and length dimensions. The sheet structure is adopted, the occupied arrangement space is small, the electronic equipment is favorably thinned, the through-current capacity of the sheet structure is better, and the circuit stability is favorably realized. The resilient conductive member 102 may also be a coil spring structure.

Specifically, when the elastic conductive member 102 has a sheet structure with a bend, the bend may be disposed at the transition portion 1023 to improve the elastic deformation capability of the transition portion 1023. The bend provided in the transition portion 1023 may be a V-shaped bend (see fig. 6, 7, 8, and 9), a U-shaped bend (see fig. 10), a W-shaped bend, or the like, and the shape of the bend provided in the transition portion 1023 is not limited herein. The bending may be disposed on the inner connecting portion 1022 or the outer connecting portion 1021 (as shown in fig. 9) to increase the contact area between the inner connecting portion 1022 and the main body portion 1012 and the contact area between the outer connecting portion 1021 and the antenna portion 1011.
