DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] First embodiment

[0030] Please refer to Figure 1 The embodiment of the present invention provides a limiting mechanism 100, which is used to open the sliding door 300 in the air conditioner 10, so as to facilitate the disassembly and cleaning of the sliding door 300. The sliding door 300 can be disassembled and cleaned by rotating, which is convenient and fast, and the rotation process is stable and reliable, the rotation texture is good, and the user experience is good.

[0031] It should be noted that the limiting mechanism 100 is applied to the sliding door 300 of the air conditioner 10, and the air conditioner 10 is an air conditioner cabinet. The air conditioner 10 is placed indoors, and the air conditioner 10 can blow hot air or cold air into the room to adjust the indoor temperature. In this embodiment, the air conditioner 10 includes an air conditioner body 200 and a sliding door 300. The sliding door 300 is connected to the air conditioner body 200 through the limiting mechanism 100, so that the sliding door 300 can rotate relative to the air conditioner body 200, so as to facilitate the disassembly and cleaning of the sliding door 300. If the sliding door 300 needs to be cleaned, the sliding door 300 is controlled to rotate a certain angle relative to the air conditioner body 200, so that the user can disassemble the sliding door 300 for cleaning; after the cleaning is completed, the sliding door 300 is installed on the air conditioner body 200, and then the sliding door 300 is controlled to rotate and reset relative to the air conditioner body 200 to achieve the cleaning operation of the sliding door 300.

[0032] The limiting mechanism 100 includes a first rotating member 110, a second rotating member 120 and a transmission rack 130. The first rotating member 110 is rotatably matched with the second rotating member 120, and the first rotating member 110 can rotate relative to the second rotating member 120. The first rotating member 110 or the second rotating member 120 is used to be fixedly connected to the sliding door 300. In this embodiment, the first rotating member 110 is fixedly connected to the sliding door 300, and the second rotating member 120 is transmission-connected to the air conditioner body 200. When the first rotating member 110 rotates relative to the second rotating member 120, the sliding door 300 also rotates relative to the air conditioner body 200, which facilitates the disassembly and cleaning of the sliding door 300.

[0033] Specifically, the air conditioner main body 200 is provided with an air outlet 210, and the air flow blown out by the air conditioner main body 200 can be blown out to the room through the air outlet 210 to realize the temperature adjustment function of the air conditioner 10. In this embodiment, the transmission rack 130 is arranged on the second rotating member 120, and the second rotating member 120 is connected to the air conditioner main body 200 through the transmission rack 130. The transmission rack 130 is used to mesh with the driving gear 201 on the air conditioner main body 200. The rotation of the driving gear 201 can drive the transmission rack 130 to move, thereby driving the sliding door 300 to move through the second rotating member 120 and the first rotating member 110 to open or close the air outlet 210, thereby realizing the start or stop of the air conditioner 10.

[0034] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6It is worth noting that the first rotating member 110 is provided with a plurality of limiting teeth 111, which are arranged at intervals and distributed in a divergent manner, and a limiting cavity 112 is formed between two adjacent limiting teeth 111. The limiting cavity 112 is used to limit the second rotating member 120 to improve the stability and rotation texture of the rotation process. The second rotating member 120 is provided with a latch 121, which is arranged between the plurality of limiting teeth 111 and extends into a limiting cavity 112. The two limiting teeth 111 forming the limiting cavity 112 can limit the latch 121 to limit the angle of each rotation of the first rotating member 110 relative to the second rotating member 120, thereby ensuring a stable and reliable rotation process. The first rotating member 110 can rotate relative to the second rotating member 120 under the action of external force, so that the latch tooth 121 disengages from the limiting tooth 111 and extends into another limiting cavity 112. During this process, the limiting tooth 111 has a certain resistance to the latch tooth 121. The user can overcome the resistance and drive the first rotating member 110 to rotate relative to the second rotating member 120 to improve the rotation texture and provide a good user experience.

[0035] In this embodiment, the shape of the latch 121 matches the shape of the limiting cavity 112. When the latch 121 extends into the limiting cavity 112, the latch 121 is clamped between the two limiting teeth 111 forming the limiting cavity 112. Both limiting teeth 111 can abut and limit the latch 121 to prevent the latch 121 from rotating freely, that is, to prevent the first rotating member 110 from rotating freely relative to the second rotating member 120. For ease of understanding, the limiting effect of the limiting tooth 111 on the latch 121 is called soft limiting. The soft limiting can prevent the first rotating member 110 from rotating freely relative to the second rotating member 120. However, the force applied by the outside can overcome the force of the soft limiting and drive the first rotating member 110 to continue to rotate relative to the second rotating member 120, so that the latch 121 is separated from the limiting tooth 111 and extends into another limiting cavity 112.

[0036] In this embodiment, the first rotating member 110 is further provided with a first limit tooth 113 and a second limit tooth 114. The first limit tooth 113 is spaced apart from the limit tooth 111, and a limit cavity 112 is formed between the first limit tooth 113 and the limit tooth 111. The latch tooth 121 extends into the limit cavity 112. The first limit tooth 113 can abut against the latch tooth 121 to prevent the first rotating member 110 from rotating relative to the second rotating member 120 along the first direction. The first limit tooth 113 can limit the first limit position of the latch tooth 121 rotating in the first direction, that is, limit the final position of the first rotating member 110 rotating relative to the second rotating member 120 along the first direction. At this time, the first rotating member 110 and the second rotating member 120 are closed, and the sliding door 300 is covered outside the air conditioner body 200. The second limit tooth 114 is arranged at an interval with the limiting tooth 111, and a limiting cavity 112 is formed between the second limit tooth 114 and the limiting tooth 111, and the latch tooth 121 extends into the limiting cavity 112. The second limit tooth 114 can abut against the latch tooth 121 to prevent the first rotating member 110 from rotating relative to the second rotating member 120 along the second direction. The second direction is opposite to the first direction. The second limit tooth 114 can limit the second limit position of the latch tooth 121 rotating in the second direction, that is, limit the final position where the first rotating member 110 can rotate relative to the second rotating member 120 along the second direction. At this time, the first rotating member 110 and the second rotating member 120 are opened to the maximum extent, and the sliding door 300 is rotated outward to the maximum extent relative to the air-conditioning body 200, which is convenient for disassembly and cleaning. However, it is not limited to this. In other embodiments, the first rotating member 110 may no longer be provided with the first limit tooth 113 and the second limit tooth 114, but may be provided with a third limit tooth. One side of the third limit tooth can limit the first limit position of the locking tooth 121 rotating in the first direction, and the other side can limit the second limit position of the locking tooth 121 rotating in the second direction. The setting form of the limit teeth is not specifically limited.

[0037] Specifically, the first limit tooth 113 and the second limit tooth 114 are relatively arranged on both sides of the plurality of limit teeth 111. When the latch tooth 121 rotates to the first limit position along the first direction, the latch tooth 121 is clamped between the first limit tooth 113 and one of the limit teeth 111. At this time, the first limit tooth 113 abuts and limits the latch tooth 121 to prevent the latch tooth 121 from continuing to rotate along the first direction. The limit tooth 111 can abut and limit the latch tooth 121 to prevent the latch tooth 121 from rotating freely. In other words, at this time, the latch tooth 121 can no longer rotate along the first direction, but can rotate along the second direction under the action of external force. When the latching tooth 121 rotates to the second limit position along the second direction, the latching tooth 121 is clamped between the second limit tooth 114 and a limiting tooth 111. At this time, the second limit tooth 114 abuts and limits the latching tooth 121 to prevent the latching tooth 121 from continuing to rotate along the second direction. The limiting tooth 111 can abut and limit the latching tooth 121 to prevent the latching tooth 121 from rotating freely. In other words, at this time, the latching tooth 121 can no longer rotate along the second direction, but can rotate along the first direction under the action of an external force. For ease of understanding, the limiting effect of the first limit tooth 113 and the second limit tooth 114 on the latching tooth 121 is called hard limiting. The hard limiting can prevent the first rotating member 110 from rotating relative to the second rotating member 120 under the action of an external force, that is, prevent the latching tooth 121 from disengaging from the first limit tooth 113 or the second limit tooth 114.

[0038] In this embodiment, the number of the limiting teeth 111 is three, and the number of the limiting cavities 112 is four, wherein a limiting cavity 112 is formed between the first limiting tooth 113 and one limiting tooth 111, two limiting cavities 112 are formed between the three limiting teeth 111, and a limiting cavity 112 is formed between the second limiting tooth 114 and one limiting tooth 111, and the latching tooth 121 can extend into any limiting cavity 112. Specifically, the angle formed by two adjacent limiting cavities 112 is 60 degrees, that is, the angle of each rotation of the latching tooth 121 is 60 degrees, and the maximum angle that the latching tooth 121 can rotate is 180 degrees. However, it is not limited to this. In other embodiments, the number of the limiting teeth 111 can be four or five, the number of the limiting cavities 112 can be five or six, and the angle formed by two adjacent limiting cavities 112 can be 30 degrees or 40 degrees. The number of the limiting teeth 111 and the size of the angle formed by two adjacent limiting cavities 112 are not specifically limited.

[0039] In this embodiment, the tooth height of the first limit tooth 113 is greater than the tooth height of the limiting tooth 111, and the increase in the tooth height can improve the limiting ability of the first limit tooth 113 on the latching tooth 121, so as to realize the hard limiting of the first limit tooth 113 on the latching tooth 121 and the soft limiting of the limiting tooth 111 on the latching tooth 121. Specifically, the tooth height of the second limit tooth 114 is equal to the tooth height of the first limit tooth 113 and greater than the tooth height of the limiting tooth 111, and the increase in the tooth height can improve the limiting ability of the second limit tooth 114 on the latching tooth 121, so as to realize the hard limiting of the second limit tooth 114 on the latching tooth 121 and the soft limiting of the limiting tooth 111 on the latching tooth 121.

[0040] It is worth noting that the latching tooth 121 and / or the limiting tooth 111 are made of elastic material to realize the soft limiting of the limiting tooth 111 on the latching tooth 121, so as to facilitate the function of the first rotating member 110 rotating relative to the second rotating member 120. In this embodiment, the latching tooth 121 is made of a rigid material, and the limiting tooth 111, the first limit tooth 113 and the second limit tooth 114 are all made of an elastic material, but it is not limited thereto. In other embodiments, the latching tooth 121 is made of an elastic material, and the limiting tooth 111, the first limit tooth 113 and the second limit tooth 114 are all made of a rigid material, or the latching tooth 121, the limiting tooth 111, the first limit tooth 113 and the second limit tooth 114 are all made of an elastic material, and the materials of the latching tooth 121, the limiting tooth 111, the first limit tooth 113 and the second limit tooth 114 are not specifically limited.

[0041] In this embodiment, the first rotating member 110 is provided with a first accommodating tube 115, and the second rotating member 120 is provided with a first fixed shaft 122. The first accommodating tube 115 is sleeved outside the first fixed shaft 122 and rotates with the first fixed shaft 122 to realize the function of the first rotating member 110 rotating relative to the second rotating member 120. The first limit tooth 113, the second limit tooth 114 and a plurality of limit teeth 111 are all arranged on the inner circumferential wall of the first accommodating tube 115, and the latch tooth 121 is arranged on the end surface of the first fixed shaft 122. The latch tooth 121 can be separated from the limit tooth 111 during the rotation of the first accommodating tube 115 relative to the first fixed shaft 122, and extend into different limit cavities 112. When the latch tooth 121 rotates to the first limit position, the first limit tooth 113 limits the latch tooth 121 to prevent the latch tooth 121 from continuing to rotate along the first direction. When the latching tooth 121 rotates to the second limit position, the second limit tooth 114 limits the latching tooth 121 to prevent the latching tooth 121 from continuing to rotate along the second direction.

[0042] Specifically, the first rotating member 110 is disposed above the second rotating member 120. When the first rotating member 110 and the second rotating member 120 need to be assembled, the first accommodating tube 115 is sleeved outside the first fixed shaft 122 from top to bottom to realize the function of the first accommodating tube 115 rotating relative to the first fixed shaft 122; when the first rotating member 110 and the second rotating member 120 need to be disassembled, the first accommodating tube 115 is pulled away from the first fixed shaft 122 from bottom to top, which is convenient for disassembly and assembly.

[0043] Furthermore, the latch tooth 121 is arranged at the top of the first fixed shaft 122, and a first limit platform 123 is arranged at one end of the first fixed shaft 122 away from the latch tooth 121. The cross-sectional area of ​​the first limit platform 123 is larger than the cross-sectional area of ​​the first fixed shaft 122. The first limit platform 123 abuts against the first accommodating cylinder 115. The first limit platform 123 can support the first accommodating cylinder 115 to prevent the first accommodating cylinder 115 from moving downward relative to the first fixed shaft 122.

[0044] Please continue to refer to Figure 1 In this embodiment, the first rotating member 110 is provided with a first buckle 116, and the second rotating member 120 is provided with a second buckle 124. The first buckle 116 can be engaged with the second buckle 124 to prevent the first rotating member 110 from rotating relative to the second rotating member 120, thereby preventing the sliding door 300 from rotating relative to the air-conditioning body 200.

[0045] When the sliding door 300 of the air conditioner 10 needs to be cleaned, the driving gear 201 is first controlled to rotate, and the driving gear 201 can drive the transmission rack 130 to move, thereby driving the entire limiting mechanism 100 to move, and then driving the sliding door 300 fixedly connected to the first rotating member 110 to move, so as to open the air outlet 210. At this time, the air conditioner 10 is in a state where air can be discharged normally, the first rotating member 110 and the second rotating member 120 are closed, the latch tooth 121 is at the first extreme position, and is in contact with the first extreme position. The limit tooth 113 abuts against the first buckle 116 and the second buckle 124; then the clamping state of the first rotating member 110 and the second rotating member 120 is released, so that the first rotating member 110 can rotate relative to the second rotating member 120, so that the sliding door 300 rotates a certain angle relative to the air conditioner body 200. When the sliding door 300 rotates to the maximum extent, the first rotating member 110 and the second rotating member 120 are opened to the maximum extent, and the clamping tooth 121 is located at the second limit position and abuts against the second limit tooth 114. At this time, the user can conveniently clean the sliding door 300. If the sliding door 300 is to be disassembled for cleaning, the first rotating member 110 is pulled away from the second rotating member 120 from bottom to top, which is convenient and quick. After cleaning, it is reset and restored in sequence to realize the cleaning operation of the sliding door 300.

[0046] The limiting mechanism 100 described in the embodiment of the present invention, the first rotating member 110 and the second rotating member 120 are rotatably matched, the first rotating member 110 or the second rotating member 120 is used to be fixedly connected to the sliding door 300, the first rotating member 110 is provided with a plurality of limiting teeth 111, the plurality of limiting teeth 111 are divergently distributed, and a limiting cavity 112 is formed between two adjacent limiting teeth 111, the second rotating member 120 is provided with a latching tooth 121, the latching tooth 121 is arranged between the plurality of limiting teeth 111 and extends into a limiting cavity 112, the first rotating member 110 can rotate relative to the second rotating member 120 under the action of external force, so that the latching tooth 121 disengages from the limiting tooth 111 and extends into another limiting cavity 112. Compared with the prior art, the limiting mechanism 100 provided by the present invention adopts a first rotating member 110 and a second rotating member 120 that rotate in coordination with each other and a latching tooth 121 arranged between a plurality of limiting teeth 111. Therefore, the disassembly, assembly and cleaning of the sliding door 300 can be achieved by rotation, which is convenient and quick, and the rotation process is stable and reliable, the rotation texture is good, and the user experience is good.

[0047] Second embodiment

[0048] Please refer to Figure 7 The present invention provides a limiting mechanism 100. Compared with the first embodiment, the difference of this embodiment is that the structures of the first rotating member 110 and the second rotating member 120 are different.

[0049] It should be noted that the first rotating member 110 is provided with a second fixed shaft 117, and the second rotating member 120 is provided with a second accommodating tube 125 having an end wall 126. The second accommodating tube 125 is sleeved outside the second fixed shaft 117 and rotatably cooperates with the second fixed shaft 117 to realize the function of the second rotating member 120 rotating relative to the first rotating member 110. The first limit tooth 113, the second limit tooth 114 and the plurality of limit teeth 111 are all arranged on the end surface of the second fixed shaft 117, and the latch tooth 121 is arranged on the end wall 126. The latch tooth 121 can be separated from the limit tooth 111 and extend into different limit cavities 112 during the process of the second accommodating tube 125 rotating relative to the second fixed shaft 117. When the latch tooth 121 rotates to the first limit position, the first limit tooth 113 limits the latch tooth 121 to prevent the latch tooth 121 from continuing to rotate along the first direction. When the latching tooth 121 rotates to the second limit position, the second limit tooth 114 limits the latching tooth 121 to prevent the latching tooth 121 from continuing to rotate along the second direction.

[0050] Specifically, the second rotating member 120 is disposed above the first rotating member 110. When the first rotating member 110 and the second rotating member 120 need to be assembled, the second accommodating tube 125 is sleeved outside the second fixed shaft 117 from top to bottom to realize the function of the second accommodating tube 125 rotating relative to the second fixed shaft 117; when the first rotating member 110 and the second rotating member 120 need to be disassembled, the second accommodating tube 125 is pulled away from the second fixed shaft 117 from bottom to top, which is convenient for disassembly and assembly.

[0051] Further, the first limit tooth 113, the second limit tooth 114 and the plurality of limit teeth 111 are all arranged on the top of the second fixed shaft 117. A second limit platform 118 is arranged at one end of the second fixed shaft 117 away from the limit tooth 111, and the cross-sectional area of ​​the second limit platform 118 is larger than the cross-sectional area of ​​the second fixed shaft 117. The second limit platform 118 abuts against the second accommodating tube 125, and the second limit platform 118 can support the second accommodating tube 125 to prevent the second accommodating tube 125 from moving downward relative to the second fixed shaft 117.

[0052] In this embodiment, the first rotating member 110 is connected to the air conditioner body 200 by transmission, and the second rotating member 120 is fixedly connected to the sliding door 300. When the second rotating member 120 rotates relative to the first rotating member 110, the sliding door 300 also rotates relative to the air conditioner body 200, so as to facilitate the disassembly and cleaning of the sliding door 300. Specifically, the transmission rack 130 is arranged on the first rotating member 110, and the first rotating member 110 is connected to the air conditioner body 200 by transmission through the transmission rack 130. The transmission rack 130 is used to mesh with the driving gear 201 on the air conditioner body 200. The rotation of the driving gear 201 can drive the transmission rack 130 to move, thereby driving the sliding door 300 to move through the first rotating member 110 and the second rotating member 120 to open or close the air outlet 210, so as to start or stop the air conditioner 10.
