DETAILED DESCRIPTION

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] Please refer to Figure 1 and Figure 2 , the embodiment provides an air conditioner shell 100, which comprises a middle frame 110, a rotating shaft 120 (please refer to Figure 3 ), an end cover 130 and a decorative connecting piece 140, wherein the middle frame 110 is provided with an air outlet 111, and the rotating shaft 120 provided with an air guide door (not shown in the figure) on one side of the air outlet 111 is used to drive the air guide door to open or close the air outlet 111.

[0049] The number of the end cover 130 is two, and the two end covers 130 are connected to the two ends of the middle frame 110 respectively. The end cover 130 is provided with a mounting groove 133. The cross section of the mounting groove 133 can be trapezoidal, rectangular or semicircular, etc. Preferably, the width of the mounting groove 133 gradually decreases along the depth direction of the mounting groove 133, which presents an open wide and narrow inside form.

[0050] Please refer to Figure 2 and Figure 3The decorative connecting piece 140 comprises a decorative strip 141 and a shaft cover 142. The shaft cover 142 is connected to one end of the decorative strip 141. The cross-sectional shape of the decorative strip 141 is the same as that of the mounting groove 133. The decorative strip 141 is mounted in the mounting groove 133. The shaft cover 142 is rotatably covered on the end of the rotating shaft 120. In this way, the shaft cover 142 covers the end of the rotating shaft 120 during rotation. When viewed from the side of the air conditioner housing, the shaft cover 142 appears to be stationary, and the rotating rotating shaft 120 cannot be seen. The end surface of the rotating shaft 120 appears to be static, and the technology is more advanced. Furthermore, the end cover 130 and the rotating shaft 120 are connected by the decorative connecting piece 140 to form a whole, which further enhances the connection strength of the end cover 130 and the rotating shaft 120, and avoids loosening and vibration noise of the end cover 130 and the rotating shaft 120 during long-term use.

[0051] In addition, the decorative strip 141 of the decorative connecting piece 140 is mounted in the mounting groove 133 of the end cover 130, so that the decorative strip 141 is fixed to the end cover 130. The shaft cover 142 connected to the decorative strip 141 is rotatably covered on the end of the rotating shaft 120. The spatial position of the rotating shaft 120 can be further fixed without affecting the rotation of the rotating shaft 120, and the loosening of the rotating shaft 120 can be avoided.

[0052] Please refer to Figure 3 and Figure 4 The shaft cover 142 is a circular ring structure, and the end of the rotating shaft 120 has a mounting column 121. The circular ring structure is sleeved on the mounting column 121. In this way, the circular ring structure of the shaft cover 142 is sleeved on the mounting column 121 at the end of the rotating shaft 120, realizing the surrounding connection of the mounting column 121 at the end of the rotating shaft 120, and making the spatial position of the rotating shaft 120 more reliable.

[0053] In addition, the outer diameter of the circular ring structure is equal to the outer diameter of the rotating shaft 120, and the inner diameter of the circular ring structure and the outer diameter of the mounting column 121 are smaller than the outer diameter of the rotating shaft 120. In this way, after the circular ring structure of the shaft cover 142 is covered on the mounting column 121 at the end of the rotating shaft 120, the outer periphery of the circular ring structure is basically flush with the outer surface of the rotating shaft 120, which not only makes the connection between the shaft cover 142 and the rotating shaft 120 more compact, but also makes the connection between the two more flat, improving the aesthetic appearance.

[0054] The inner diameter of the circular ring structure can also be designed to be equal to or slightly smaller than the outer diameter of the mounting column 121, so that the circular ring structure of the shaft cover 142 can be in interference fit with the mounting column 121. The circular ring structure has a certain clamping force on the mounting column 121, making the connection between the two stable. Of course, the contact surface between the circular ring structure and the mounting column 121 is smooth, so that the circular ring structure and the mounting column 121 can rotate relative to each other. At the same time, the decorative strip 141 can provide a certain supporting force to the shaft cover 142, which is conducive to the stable covering of the shaft cover 142 on the end of the rotating shaft 120.

[0055] In other embodiments, the shaft cover 142 can also be a barrel structure, and the shaft cover 142 with the barrel structure can completely cover the mounting column 121 at the end of the rotating shaft 120, so that the end surface of the rotating shaft 120 is completely not exposed, and a static visual effect is completely presented.

[0056] Please refer to Figure 5 and Figure 6 The bottom surface of the mounting groove 133 is provided with a clamping groove 134, and the decorative strip 141 is provided with a clamping block 143 matched with the clamping groove 134. In this way, not only the decorative strip 141 is mounted in the mounting groove 133 of the end cover 130, but also the connection strength between the decorative strip 141 and the end cover 130 is further enhanced by the clamping groove 134 and the clamping block 143, so as to avoid dislocation of the decorative strip 141 relative to the end cover 130, and meanwhile, the clamping block 143 on the decorative strip 141 is clamped into the clamping groove 134 when the decorative strip 141 is mounted into the mounting groove 133, without increasing the assembly difficulty.

[0057] The clamping block 143 can have a structure with a large head and a small root, and the size of the head of the clamping block 143 is slightly larger than the size of the clamping groove 134, that is, the head of the clamping block 143 passes through the bottom wall of the clamping groove 134 after a certain degree of deformation, and the root of the clamping block 143 is located in the clamping groove 134, so that the head of the clamping block 143 abuts against the inner side surface of the end cover 130, and the clamping block 143 is not easy to fall off from the clamping groove 134. Here, the inner side surface of the end cover 130 refers to the surface of the end cover 130 close to the middle frame 110.

[0058] The decorative connecting piece 140 is an integral structure and is made of elastic material, that is, the decorative strip 141, the shaft cover 142 and the clamping block 143 are integrally formed by injection molding, and can be made of elastic materials such as rubber. In this way, the structural strength of the decorative strip 141 is large, and the decorative strip 141 has a certain deformation capacity, which can facilitate the mounting of the decorative strip 141 into the mounting groove 133 of the end cover 130 and the covering of the shaft cover 142 on the end of the rotating shaft 120.

[0059] The mounting groove 133 is arranged at the edge of the end cover 130, and the length of the mounting groove 133 is greater than or equal to 1 / 2 of the length of the edge of the end cover 130, and the length of the decorative strip 141 is equal to the length of the mounting groove 133. In this way, the decorative strip 141 is arranged along the edge of the end cover 130, which can improve the decoration effect, and the long length of the mounting groove 133 and the decorative strip 141 can improve the connection strength between the decorative strip 141 and the end cover 130.

[0060] Specifically, the end cover 130 comprises a horizontal plate 131 and a vertical plate 132, wherein the horizontal plate 131 covers the top surface of the middle frame 110, and the vertical plate 132 is connected to the edge of the horizontal plate 131 and covers the end surface of the middle frame 110. In this way, the end cover 130 is connected to the top surface and the end surface of the middle frame 110, which can improve the connection stability of the end cover 130 and the middle frame 110, and further strengthen the connection strength of the end cover 130 and the middle frame 110 under the action of the gravity of the end cover 130 itself.

[0061] The mounting groove 133 extends from the horizontal plate 131 to the vertical plate 132, and the decorative strip 141 fills the mounting groove 133. In this way, the mounting groove 133 and the decorative strip 141 are not only arranged on the horizontal plate 131 of the end cover 130, but also arranged on the vertical plate 132 of the end cover 130. The horizontal plate 131 and the vertical plate 132 are substantially perpendicular in spatial position, so there is a turning point, and the decorative strip 141 also has a turning point, which can further strengthen the connection strength of the decorative strip 141 on the end cover 130.

[0062] Here, "substantially perpendicular" can be generally understood as an angle between 80-110°, in other words, it does not require strict 90° perpendicularity. Moreover, the connection between the horizontal plate 131 and the vertical plate 132 does not require strict perpendicularity to each other, but can be a smooth transition.

[0063] Preferably, the mounting groove 133 starts from the edge of the horizontal plate 131 close to the back surface of the middle frame 110 and extends along the edge of the vertical plate 132 to the edge of the vertical plate 132 close to the front surface of the middle frame 110. In this way, the length of the decorative strip 141 and the mounting groove 133 is sufficient, which not only improves the connection strength of the decorative strip 141 on the end cover 130, but also makes the decorative effect of the decorative strip 141 on the end cover 130 better.

[0064] In other embodiments, the mounting groove 133 can also extend from the middle of the horizontal plate 131 to the middle of the vertical plate 132 and finally extend to the edge of the vertical plate 132 close to the front surface of the middle frame 110. In this way, the decorative strip 141 can also be well fixed and have a good decorative effect.

[0065] Please refer to Figure 7 The embodiment also provides an end cover 130, wherein an auxiliary connecting cover 135 is arranged on the end cover 130, the auxiliary connecting cover 135 is rotatably connected to the end of the rotating shaft 120, and the shaft cover 142 is connected to the end of the rotating shaft 120 through the auxiliary connecting cover 135.

[0066] Specifically, please refer to Figure 8 and Figure 9The auxiliary connecting cover 135 is in a barrel structure and has a positioning hole 136 in the middle part, and the auxiliary connecting cover 135 is rotatably covered on the end of the rotating shaft 120. Correspondingly, the shaft cover 142 is provided with a positioning column 144, and the positioning column 144 is matched with the positioning hole 136, so that the shaft cover 142 is covered on the end of the rotating shaft 120 through the auxiliary connecting cover 135.

[0067] The embodiment also provides an indoor unit, which comprises the air conditioner shell 100, and of course, the indoor unit also comprises conventional air conditioner parts, such as an evaporator, a guide vane, an auxiliary heater and the like, which are not described herein. In this way, the indoor unit provided by the embodiment not only beautifies the appearance of the end cover 130, but also strengthens the connecting strength of the end cover 130 and the rotating shaft 120, so that loosening and noise of the end cover 130 and the rotating shaft 120 are avoided.
