The physical keys 120 integrated with the screen component 132 may be disposed above, below, or on the side of the screen component 132.

Referring to fig. 3 to 6, in an embodiment, the door 131 has a screen mounting area 1313, and the screen mounting area 1313 is a mounting cavity matched with the shape of the screen assembly 132. Specifically, in one embodiment, the door 131 has a frame 1311 and a support beam 1312 disposed on the frame 1311, the support beam 1312 divides the frame 1311 into a window installation region (a position where the window 133 is installed) and a screen installation region 1313, the window 133 is fixed in the window installation region, and the screen assembly 132 is fixed in the screen installation region 1313. The transparent window 133 is made of transparent plastic, and is formed as an integrated structure with the frame 1311 through a two-color injection molding process.

Referring to FIG. 6, the side wall of the mounting chamber has a ring of supports 1314 for supporting the screen assembly 132. The outer panel 1322, the touch panel 1323, and the display 1324 are stacked in this order. The periphery of the outer panel 1322 protrudes from the touch screen 1323. In some embodiments, the touch screen 1323 protrudes from the display 1324, but it is also possible to assemble the touch screen 1323 and the display as a whole. The protruding portion of the outer panel 1322 is mounted on the support 1314 and is adhesively fixed to the door body 131. The bonding method can fix the screen assembly 132 to the door 131. Wherein, better, this glue solution can adopt the thermal reaction to glue, and this thermal reaction glues the back and forms elasticity flexible glue that solidifies, under the condition that satisfies the fixed demand to screen subassembly 132, plays buffering guard action and waterproof function to screen subassembly 132. Moreover, the thermal reaction adhesive is not easy to corrode, and can meet the higher requirements of cleaning and disinfection in medical equipment.

Further, in an embodiment, the supporting platform 1314 is provided with a dispensing slot 1315 for accommodating glue solution. The dispensing slot 1315 is provided with a circle inside the mounting cavity.

The dispensing grid 1317 can contain the glue therein to avoid uneven distribution of the glue in each part of the dispensing slot 1315. The glue solution is uniformly distributed at each position of the glue dispensing groove 1315, so that the thickness of the glue solution after the screen is pasted can be accurately controlled, the requirement of bonding is met, and the problem of reliability caused by deformation of the door body part is solved. Particularly, the gluing structure can meet the gluing requirement of an extremely narrow frame, for example, under the condition that the size of the outer panel 1322 protruding out of the touch screen 1323 is 0.5mm-1mm, the common gluing structure is difficult to realize, but the gluing structure is feasible.

In an embodiment, the protruding portion 1316 can directly cut off the dispensing slot 1315 to form a closed dispensing grid 1317, so as to prevent the glue in the dispensing grid 1317 from running off and ensure the gluing effect.

In one embodiment, the raised portion 1316 does not directly separate the dispensing slot 1315, but reserves a part of gap for the connection between the dispensing grids 1317, so that the glue flows adaptively during dispensing, thereby improving dispensing efficiency.

In some embodiments, the length of the dispensing grid 1317 at the corner is greater than that of the dispensing grids 1317 at other non-corners, so that the dispensing grid 1317 at the corner can accommodate more glue. The glue dispensing grids 1317 at the non-corners can be set to be equal in length, so that glue in the glue dispensing grids 1317 are basically consistent, and batch operation of the glue dispenser is facilitated.

Further, referring to fig. 5 and 6, in one embodiment, the peripheral projection of the outer panel 1322 is located above the support 1314 and encloses a first adhesive region a with the support 1314 and/or the sidewall of the mounting chamber.

In some embodiments, the protruding portion of the periphery of the touch screen 1323 and the sidewall of the display screen 1324 and the sidewall of the support 1314 form a second adhesive region b.

When the glue solution distribution dispensing slot 1315, the glue dispensing slot 1315 and the support 1314 will deform after press-bonding, so that the redundant glue solution automatically overflows into the first gluing area a and/or the second gluing area b, the gluing area is increased, the bonding strength is increased, and the requirement of periphery waterproofing is met.

In order to further prevent water from entering the door 131 from the gap between the screen assembly 132 and the side wall of the installation cavity, in one embodiment, a water guiding groove is formed in the door 131, the gap between the screen assembly 132 and the side wall of the installation cavity is communicated with the water guiding groove, and the water guiding groove extends to the outside of the door 131 to guide out the water in the gap. The outlet of the water chute may be disposed at the bottom of the door 131, so as to guide the water out of the bottom of the door 131.

In order to further enhance the waterproof effect, the outer side edge of the outer panel 1322 is sleeved with a rubber ring, and the rubber ring is arranged between the wall of the installation cavity (screen installation area 1313) and the outer panel 1322.

Besides the above-mentioned adhesive sealing fit, the screen assembly 132 and the door 131 can also be full-screen at the periphery of the screen assembly 132 by soft glue interference, for example, only the above-mentioned rubber ring is used for waterproof sealing.
