Thus, when the terminal device is used, the operating key 12 can trigger the electrical signal element 13 through the pressing part 12a when moving on the housing body 100, so that the electrical signal element 13 generates an electrical signal. In this process, the operation key 12 is movably disposed, causing it to be loosely fitted with the mounting hole 140. When the foreign matters such as liquid enter the mounting groove 120 along the mounting hole 140, the mounting groove 120 is reliably sealed by the sealing unit 300, so that the sealing unit 300 can prevent the foreign matters such as liquid from permeating into the terminal equipment from the mounting groove 120, the waterproof performance of the terminal equipment is effectively improved, the electronic devices such as a control mainboard are prevented from being damaged, and the reliability of the terminal equipment is improved.

In addition, it is understood that, as the portion of the electric signal element 13 is disposed in the mounting groove 120, the waterproof performance can be improved by disposing the waterproof layer 13 a. By using the shell assembly 11, the waterproof processing requirements on other electronic devices of the terminal equipment are reduced under the condition that the waterproof effect of the terminal equipment can be ensured.

It should be noted that the electrical signal element 13 includes a switch or a sensor capable of generating an electrical signal (e.g. 0, 1), such as a movable switch and an inductive switch, so as to complete the activation or the use of a specific function on the terminal device. Wherein, the movable switch comprises a button switch, a pull-plug switch, a spring switch and the like. The inductive switch comprises a magnetic displacement inductive switch, a photoelectric inductive switch, a pressure inductive switch and the like.

Thus, when the operation key 12 is in the open state, the operation key 12 is pressed, and the electric signal element 13 generates an electric signal, so that similar game commands such as 'shooting', 'going back to town', 'going back' and the like can be sent out, and a better game operation experience is given to a user.

Furthermore, the operation keys 12 are used for starting and closing the video recording mode; alternatively, the operation keys 12 are used for starting and closing the specific photographing mode. Alternatively, the operation key 12 is used as a key to turn on or off a function, such as turning on and off an APP, starting or off an automatic timer, starting or off an automatic recording, turning on or off an NFC function, and so on.

As shown in fig. 3, in one embodiment, the housing body 100 is a middle frame. Thus, the antenna support 200, the sealing unit 300, the electrical signal unit, the control mainboard, the operation key 12 and the like are directly assembled on the middle frame, so that the structure of the terminal device is more compact, and the requirement of miniaturization development of the terminal device can be met.

The sealing unit 300 may be formed by at least one sealing member, and a sealing structure capable of sealing the mounting groove 120 may be formed. The sealing of the mounting groove 120 is achieved, for example, using waterproof foam and/or waterproof silicone, and the like.

As shown in fig. 2 and 3, in some embodiments, the mounting groove 120 includes a limiting sidewall 121 disposed opposite to the mounting hole 140, and a portion of the sealing unit 300 is fixedly pressed above the limiting sidewall 121 by the antenna bracket 200. So, set firmly between spacing lateral wall 121 and antenna boom 200 through the extrusion with sealed unit 300, can seal the gap between antenna boom 200 and the spacing lateral wall 121, guarantee sealed effect.

In addition to any of the above embodiments, in some embodiments, the antenna holder 200 is fixedly connected to at least a portion of the sealing unit 300. In this way, when the antenna bracket 200 is assembled, at least a part of the sealing unit 300 can be fixedly connected to the antenna bracket 200 at the same time, and then when the antenna bracket 200 is assembled to the housing body 100, the sealing unit 300 is disposed at the edge of the mounting groove 120, so that the mounting and fixing of the sealing unit 300 are realized while the mounting and fixing of the antenna bracket 200 to the housing body 100 are completed, and the assembly efficiency of the housing assembly 11 is further improved.

In one example, the antenna mount 200 is positioned to mate with the sealing unit 300 to secure the sealing unit 300 to the antenna mount 200. For example, the positioning grooves and/or the positioning protrusions of the antenna holder 200 are used to be positioned and engaged with the sealing unit 300.

In addition to any of the above embodiments, in some embodiments, the sealing unit 300 includes a plurality of sealing members, at least two of the sealing members have different elastic deformation amounts, and the sealing member with the larger elastic deformation amount is clamped between the antenna bracket 200 and the mounting surface 110. Thus, the sealing unit 300 is formed by matching a plurality of sealing members, so that the sealing requirements of different positions of the mounting groove 120 can be met, and the mounting groove 120 is more reliable in sealing. In addition, the sealing member having a large elastic deformation amount is clamped between the antenna holder 200 and the mounting surface 110, so that the tolerance capability of the sealing unit 300 can be improved, and the mounting groove 120 can be reliably sealed without being affected by manufacturing errors and assembly errors of the housing body 100 and/or the antenna holder 200.

It should be noted that a plurality of sealing members can be integrally formed or coupled together to seal the mounting groove 120. Wherein, the sealing connection fit comprises bonding or overlapping arrangement and the like.

On the basis of the above embodiments, in some embodiments, a partial region between two adjacent sealing members is overlapped. So, utilize to overlap and set up two sealing members and can transmit the extrusion force each other, effectively avoid outside water to get into terminal equipment from mounting groove 120 inside, improve terminal equipment's waterproof performance.

Alternatively, the sealing member having a large elastic deformation amount includes waterproof foam or the like.

On the basis of any of the above embodiments, as shown in fig. 2 and fig. 4 to 6, in some embodiments, the sealing unit 300 includes a first sealing member 310, and the first sealing member 310 is fixedly disposed on the antenna bracket 200 and is in sealing engagement with the mounting groove 120. The first sealing member 310 may be fixed to the antenna holder 200 by various fixing means such as adhesion and fastening. In this way, when the antenna bracket 200 is assembled, the first sealing member 310 can be fixedly connected to the antenna bracket 200 at the same time, and then when the antenna bracket 200 is assembled to the housing body 100, the first sealing member 310 is disposed at the edge of the mounting groove 120, so that the first sealing member 310 and the mounting groove 120 are reliably and hermetically matched while the antenna bracket 200 is mounted and fixed to the housing body 100, and the assembly efficiency of the housing assembly 11 can be improved.

As shown in fig. 6, in some embodiments, the first sealing member 310 is provided with a first positioning portion 311, and the antenna bracket 200 is provided with a second positioning portion 220 which is in positioning fit with the first positioning portion 311. One of the first positioning portion 311 and the second positioning portion 220 is a positioning concave portion, and the other is a positioning convex portion engaged with the positioning concave portion. The positioning concave part comprises a positioning hole, a positioning groove, a positioning notch and the like. In this way, the first positioning portion 311 and the second positioning portion 220 are in positioning fit, so that the first sealing member 310 is fixed on the antenna bracket 200, and the operation is simple and the assembly is easy.

Based on any of the above-mentioned embodiments of the first sealing member 310, as shown in fig. 2 and fig. 4 to 6, in some embodiments, the sealing unit 300 further includes a second sealing member 320 having a larger elastic deformation than the first sealing member 310, the second sealing member 320 is clamped between the antenna bracket 200 and the mounting surface 110, and the second sealing member 320 cooperates with the first sealing member 310 to seal the mounting groove 120. In this way, the sealing requirements of different positions of the installation groove 120 can be met by the cooperation of the first sealing element 310 and the second sealing element 320, and the installation groove 120 is more reliably sealed. In addition, the second sealing member 320 having a large elastic deformation amount is clamped between the antenna holder 200 and the mounting surface 110, so that the tolerance capability of the sealing unit 300 can be improved, and the mounting groove 120 can be reliably sealed without being affected by manufacturing errors and assembly errors of the housing body 100 and/or the antenna holder 200.

In this way, the structural characteristics of the outer edge of the mounting groove 120 and the amount of elastic deformation of the sealing unit 300 are fully utilized. Because the elastic deformation amount of the first sealing member 310 is relatively small, the sealing effect can be ensured by using the surface sealing of the first sealing member 310 and the outer edge of the mounting groove 120, and because the elastic deformation amount of the second sealing member 320 is relatively large, the sealing effect can be ensured by using the second sealing member 320 to realize the extrusion sealing with the outer edge of the mounting groove 120, the sealing effect on the mounting groove 120 can be ensured by using the overlapping part of the first sealing member 310 and the second sealing member 320 to realize the surface sealing and the extrusion sealing, and the extrusion force applied to the first sealing member 310 by the antenna bracket 200 is transmitted through the second sealing member 320, so that the first sealing member 310 is in close contact with the shell body 100, thereby effectively avoiding the external water from entering the terminal device from the mounting groove 120, and improving the waterproof performance of the terminal device.

In combination with the above-mentioned embodiment of the position-limiting sidewall 121, the second sealing element 320 is fixedly pressed by the antenna bracket 200 above the position-limiting sidewall 121. Thus, by using the characteristic that the elastic deformation amount of the second sealing member 320 is relatively large, the second sealing member 320 is used to realize the extrusion sealing with the limiting side wall 121 to ensure the sealing effect, and the mounting groove 120 is reliably sealed without being influenced by the manufacturing error and the assembling error of the housing body 100 and/or the antenna bracket 200.

Further, as shown in fig. 2 to 5, in some embodiments, the mounting surface 110 includes a mating surface 111 disposed between the mounting groove 120 and the mounting side surface 130 and a mating end 112 disposed between the mating surface 111 and the position-limiting side wall 121. In this way, in the orthographic projection direction of the mounting surface 110, the mating surface 111 is in surface sealing fit with the first sealing element 310, the second sealing element 320 is in compression sealing with the limiting side wall 121, and the mating end 112 can be in surface sealing and compression sealing by using the overlapping portion of the first sealing element 310 and the second sealing element 320, that is, the second sealing element 320 is used to transmit the compression force applied to the first sealing element 310 by the antenna bracket 200, so that the first sealing element 310 is in close contact with the housing body 100, and the sealing effect on the mounting groove 120 is fully ensured.

In addition to any of the above embodiments of the position-limiting side wall 121, as shown in fig. 2, in some embodiments, the position-limiting side wall 121 includes a protruding strip 101 formed on the mounting surface 110, and the antenna holder 200 and the protruding strip 101 press the second sealing member 320.

Like this, when guaranteeing the extrusion effect, guarantee second sealing member 320 and sand grip 101 area of contact to improve waterproof sealing effect.

Optionally, in some embodiments, the width of the second seal 320 is greater than or equal to 1 mm. In this way, the sealing effect can be ensured, and the assembly accuracy requirement of the second sealing member 320 can also be reduced.

As such, the tolerance capability of the sealing unit 300 may be further improved by compressing the second sealing member 320 with the elastic layer 210. In addition, the elastic layer 210 is reliably contacted with the second sealing member 320, so that the influence on the sealing effect caused by the unreliable contact between the antenna support 200 and the second sealing member 320 due to the elastic deformation of the second sealing member 320 is avoided.
