FIG. 1 is a schematic illustration of a housing assembly shown according to an exemplary embodiment. FIG. 2 is a schematic view of a housing assembly shown in accordance with another exemplary embodiment. FIG. 3 is a schematic view of a housing assembly shown in accordance with yet another exemplary embodiment. Please refer to fig. 1-3.

As shown in fig. 1, the present embodiment provides a housing assembly, which includes a first housing and a second housing, wherein at least one sliding rail structure (not shown in the drawings) is disposed between the first housing and the second housing; the first housing comprises an antenna 100, the second housing comprises at least one metal area 200, and the antenna 100 and the metal area 200 are connected through at least one flexible inductor 300.

Specifically, the housing assembly of the present embodiment is used for a sliding terminal device, and the terminal device may be a mobile phone, a computer, a tablet device, a personal digital assistant, a medical device, a fitness device, etc., and the present embodiment is not limited to a specific form.

The first housing in this embodiment may be a front housing of the terminal device, and the corresponding second housing may be a rear housing of the terminal device. The front casing and the rear casing of the terminal device may be made of casing materials commonly used in the prior art, for example, materials such as metal, plastic, and ceramic may be used, which is not further limited in this embodiment.

The projection areas of the first shell and the second shell before relative sliding are basically overlapped, and the first shell covers the second shell to form a shell assembly. Before relative sliding, the antenna 100 is directly connected with the metal area 200, so that a conductive loop is formed between the antenna 100 and the metal area 200, when a human body touches the mobile phone, if static electricity is carried on the human body, the static electricity is guided to the metal area 200 after passing through the antenna 100, and then the static electricity is discharged through a grounding end on the metal area 200.

When the first housing and the second housing slide relatively, the antenna 100 and the metal area 200 are separated from each other in position, and at this time, the flexible inductor 300 is used to connect the two. The flexible inductor 300 has a low resistance, and since the charges are preferentially conducted from a low-resistance place, in this state, if static electricity is carried on a human body when the human body touches the mobile phone, the static electricity is guided to the metal area 200 through the antenna 100 and the flexible inductor 300, and is discharged through the grounding end of the metal area 200, so that the static electricity is not accumulated in the clearance area 400, and the use safety of the mobile phone is ensured.

Specifically, the antenna 100 is connected to the metal area 200 through at least one flexible inductor 300 to form an electrostatic discharge loop, which specifically includes:

at least one electrostatic discharge point 110 is arranged at the receiving end of the antenna 100; the metal region 200 below the clearance area 400 is provided with at least one electrostatic discharge endpoint 210;

the electrostatic discharge point 110 is connected to the electrostatic discharge end point 210 via the flexible inductor 300 to form an electrostatic discharge loop.

according to the invention, at least one flexible inductor 300 is arranged between the antenna 100 of the first shell and the metal area 200 of the second shell, and the flexible inductor 300 has good conductivity, so that a conductive loop can be formed between the antenna 100 and the metal area 200, and static electricity in the clearance area 400 is transmitted to the grounding end on the metal area 200 through the conductive loop, so that static electricity discharge is realized, normal use of the mobile phone is guaranteed, and potential safety hazards are reduced.

Further, the metal region 200 may be located on a metal middle frame of the terminal device. The metal area 200 is arranged on the metal middle frame, static electricity leakage can be carried out by utilizing the existing structure of the metal middle frame, additional parts are not needed, and the number of parts of the terminal equipment is reduced.

Further, a connection line between the electrostatic discharge point 110 and the projection of the electrostatic discharge end point 210 in the plane in which the first housing and the second housing slide relatively is parallel to the sliding direction of the first housing and the second housing. That is, the electrostatic discharge point 110 and the electrostatic discharge end point 210 are disposed on the same side of the housing assembly, such that a connection line between projections of the electrostatic discharge point 110 and the electrostatic discharge end point 210 on a plane where the housing assembly slides relative to each other is parallel to a straight line indicated by a direction in which the housing assembly slides relative to each other, thereby reducing a distance between the electrostatic discharge point 110 and the electrostatic discharge end point 210.

Further, when the first housing and the second housing are in the sliding-open state, the distance between the electrostatic discharge point 110 and the electrostatic discharge end point 210 is equal to the length of the flexible inductor 300 in the free state. Through the arrangement, the length of the flexible inductor 300 can be minimized, so that the resistance value of the flexible inductor 300 is further reduced, and the conductivity of the flexible inductor is improved; in addition, the connection mode also enables the stress of the connection point of the flexible inductor 300 and the metal area 200 to be more uniform, improves the connection stability, and prolongs the service life of the equipment.

Specifically, in this embodiment, the flexible inductor 300 may be connected to the antenna 100 and the metal area 200 by soldering.

More closely, the specific form of the welding can be laser welding, which is an efficient and precise welding method using a laser beam with high energy density as a heat source, and has high welding precision, short welding time, small heat productivity, small welding stress, and no deformation after welding, thereby ensuring high welding quality, substantially ensuring consistent welding impedance at the connecting point of the flexible inductor 300 and the antenna 100 and the metal area 200, and improving stability during use.

Further, the flexible inductor 300 may be a flexible circuit board made of a magnetic material. The magnetic material in this embodiment may be any suitable magnetic material in the prior art, such as nickel zinc ferrite or manganese zinc ferrite, and this embodiment does not limit this.

Further, the inductance value of the flexible inductor 300 is preferably 33 to 100nh, and setting the inductance value within this range enables good discharge of static electricity.

When the antenna 100 is connected to the metal area 200 through a flexible inductor 300, the flexible inductor 300 is preferably disposed in the middle of the antenna 100 and the metal area 200, so as to minimize the average value of the conductive paths of static electricity transmitted in all directions, reduce the time of static electricity leakage, and improve the safety of use.

As shown in fig. 2, based on the above description, in another possible embodiment, two flexible inductors 300 are disposed between the antenna 100 and the metal area 200, and the two flexible inductors 300 are symmetrically disposed with respect to the perpendicular bisector of the metal area 200. For example, one of the flexible inductors 300 may connect a quarter length of the antenna 100 to a quarter length of the metal region 200, and the other flexible inductor 300 may connect a three quarter length of the antenna 100 to a three quarter length of the metal region 200.

Specifically, the flexible inductor 300 in this embodiment includes a first flexible circuit board 310 and a second flexible circuit board 320, and in the direction from right to left in fig. 2, the first flexible circuit board 310 may connect a quarter length of the antenna 100 to a quarter length of the metal area 200, and the second flexible circuit board 320 may connect a three quarter length of the antenna 100 to a three quarter length of the metal area 200. As shown in fig. 2, static electricity enters the housing assembly from the antenna 100, and due to the presence of the first flexible circuit board 310 and the second flexible circuit board 320, the static electricity will be discharged through the nearest discharge paths, i.e. the static electricity will be guided onto the metal area 200 through the first flexible circuit board 310 and the second flexible circuit board 320 respectively in the directions shown by arrows in fig. 2, and thus be discharged through the ground terminal on the metal area 200.

As shown in fig. 3, based on the above description, in yet another possible embodiment, three flexible inductors 300 are disposed between the antenna 100 and the metal area 200, wherein a first flexible inductor 300 connects the middle of the antenna 100 and the middle of the metal area 200, and a second flexible inductor 300 and a third flexible inductor 300 are symmetrically disposed with respect to the perpendicular bisector of the metal area 200. For example, a first flexible inductor 300 may connect a quarter of the length of the antenna 100 to a quarter of the length of the metal area 200, a second flexible inductor 300 may connect the middle of the antenna 100 to the middle of the metal area 200, and a third flexible inductor 300 may connect three quarters of the length of the antenna 100 to three quarters of the length of the metal area 200.

Specifically, the flexible inductor 300 in this embodiment includes a third flexible circuit board 330, a fourth flexible circuit board 340, and a fifth flexible circuit board 350, in the direction from right to left in fig. 3, the third flexible circuit board 330 may connect the one-fourth length of the antenna 100 and the one-fourth length of the metal area 200, the fourth flexible circuit board 340 may connect the middle of the antenna 100 and the middle of the metal area 200, and the fifth flexible circuit board 350 may connect the three-fourth length of the antenna 100 and the three-fourth length of the metal area 200. When static electricity is discharged, the nearest discharge path is preferably discharged, so that the use safety of the mobile phone is ensured.

In other possible embodiments, a plurality (more than three) of flexible inductors 300 may be further disposed between the antenna 100 and the metal area 200, and the flexible inductors 300 are uniformly distributed, so as to ensure uniformity of the length of the electrostatic discharge path.
