Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an emergency switch pressing structure and an air conditioner. Background Art

[0002] The air conditioner uses an infrared remote control to turn the unit on and off. However, an emergency switch needs to be set to prevent the remote control from being damaged or repaired. There are currently two ways to set emergency switches for air conditioner indoor units on the market. One is to open a hole on the control box cover, which requires external tools and is not easy to operate. The other is to press a button with a plastic elastic wall structure, such as the utility model patent with announcement number CN218296200U titled "Casing Upper Cover and Air Conditioner Indoor Unit". The elastic wall of this method is prone to aging and will lose the pressing function after repeated use. Utility Model Content

[0003] In view of the deficiencies existing in the prior art, the utility model provides an emergency switch pressing structure to solve the technical problems in the related art that the traditional emergency switch pressing structure is difficult to operate and easy to age.

[0004] The utility model provides an emergency switch pressing structure, comprising:

[0005] A lower cover is formed with a mounting compartment;

[0006] An upper cover is detachably arranged on the lower cover, and an upper end surface of the upper cover is provided with a mounting groove, wherein the mounting groove has a mounting opening communicating with the mounting bin and a plurality of limiting openings, and the plurality of limiting openings are arranged around the mounting opening;

[0010] A plurality of springs are respectively sleeved on each of the step screws, one end of the spring extends into the limit opening, and the other end thereof abuts against the pressing handle, so that the pressing handle is pressed under the action of an external force to compress the spring, and the spring is reset after the external force disappears.

[0011] Furthermore, the installation groove is provided with a first limiting table surface for abutting against or separating from the pressing handle.

[0012] Furthermore, a protrusion is provided at one end of the step screw away from the pressing handle, and the protrusion is exposed outside the corresponding limiting opening.

[0013] Furthermore, the stepped screw and the protrusion are configured to form an inverted T-shaped structure.

[0014] Furthermore, the limiting opening is provided with a second limiting table surface for abutting against or separating from the protrusion.

[0015] Furthermore, one end of the step screw rod close to the pressing handle is threadedly penetrated through the pressing handle, and a nut is threadedly provided on the end.

[0016] Furthermore, the pressing handle is provided with a plurality of through holes for accommodating the step screws.

[0017] Furthermore, the pressing column is provided with a plurality of reinforcing ribs along its length direction.

Each limit opening cooperates with the corresponding step screw to provide a precise sliding guide for the pressing handle; 2. The use of the spring in conjunction with the step screw allows a smooth and feedback force to be felt when the pressing handle is pressed. When external force is applied to the pressing handle, the spring is compressed, providing a certain sense of resistance, ensuring the stability of the operation. Once the external force is removed, the elastic potential energy of the spring causes the pressing handle to automatically reset without manual rebound, thereby improving the convenience and durability of use. The pressing column can be powered off by abutting against the emergency switch; 3. Through the limiting effect of the limit opening and the step screw, damage caused by excessive pressing can be effectively prevented, while ensuring the instant and accurate action of the switch, thereby improving the safety performance of the equipment in emergency situations.

[0031] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] See also Figures 1 to 5 The utility model provides an emergency switch pressing structure, comprising:

[0033] The lower cover 1 is formed with a mounting compartment 101;

[0034] An upper cover 2 is detachably provided on the lower cover 1, and an installation groove 201 is provided on the upper end surface of the upper cover 2. The installation groove 201 has an installation opening 202 communicating with the installation bin 101 and a plurality of limiting openings 203, and the plurality of limiting openings 203 are arranged around the installation opening 202;

[0035] A pressing handle 3, slidably disposed in the mounting groove 201;

[0036] A pressing column 4 is fixed to the pressing handle 3, and the pressing column 4 extends into the installation bin 101 through the installation opening 202;

[0037] A plurality of stepped screw rods 5 are arranged corresponding to the plurality of the limiting openings 203 , and each of the stepped screw rods 5 is arranged on the pressing handle 3 along the length direction of the pressing column 4 ;

[0038] A plurality of springs 6 are respectively sleeved on each of the step screws 5, one end of the spring 6 extends into the limiting opening 203, and the other end thereof abuts against the pressing handle 3, so that the pressing handle 3 is pressed under the action of an external force to compress the spring 6, and the spring 6 is reset after the external force disappears.

[0039] In this embodiment, a lower cover 1 is installed at the circuit board of the air conditioner. The lower cover 1 is formed with an installation chamber 101 for covering the circumference of the circuit board. An upper cover 2 is detachably provided above the installation chamber 101 for closing the installation chamber 101, which can effectively prevent dust and mosquitoes from entering the installation chamber 101 and causing damage to the circuit components of the air conditioner. An installation groove 201 is provided on the upper end surface of the upper cover 2. The installation groove 201 is provided with an installation opening 202 and a plurality of limit openings 203 connected to the installation chamber 101. The pressing handle 3 is slidably provided in the installation groove 201. The pressing column 4 is fixed on the pressing handle 3 and is used to extend into the installation bin 101 through the installation opening 202. When an emergency power-off operation is required, the operator presses the pressing handle 3, and the pressing column 4 fixed thereon enters the installation bin 101 through the linkage of the pressing handle 3. The pressing handle 3 is combined with the installation bin 101 of the lower cover 1 through the installation groove 201 of the upper cover 2, ensuring that the pressing handle 3 slides stably in the installation bin 101, avoiding misoperation or shaking of the pressing handle 3 when sliding, and improving the reliability and accuracy of use. The screw rod 5 cooperates to provide precise position guidance for the moving path of the pressing handle 3, so that it can slide smoothly up and down along the installation bin 101 to perform the power-off action; on the other hand, a spring 6 is sleeved on each step screw rod 5, one end of the spring 6 extends into the limit opening 203, and the other end abuts against the pressing handle 3. The cooperation of the spring 6 and the step screw rod 5 provides appropriate resistance for the pressing operation, so that the operator can clearly perceive the pressing process and force until the pressing limit position is reached, which not only ensures the stability of the operation, but also provides clear tactile feedback, thereby improving the user experience. When the external force is released, the elastic force of the spring 6 drives the pressing handle 3 to return to the initial position, thereby realizing automatic resetting without manual intervention. The cooperation of the limit opening 203 and the step screw rod 5 not only limits the moving range of the pressing handle 3, thereby avoiding damage caused by excessive pressing, but also ensures the instant and accurate switching action, thereby improving the safety performance of the equipment in emergency situations, and also disperses the stress generated during the pressing process through cooperation with the spring 6, thereby increasing the stability and durability of the entire device.

[0040] The installation groove 201 is provided with a first limiting table 204 for contacting or separating with the pressing handle 3 .

[0041] In this embodiment, the first limit table 204 serves as a limit point for the downward movement of the pressing handle 3. When the pressing handle 3 abuts against it, the operator can clearly feel that the pressing process has reached the preset limit position, which helps to ensure the accurate execution of emergency operations and avoid excessive pressing. At the moment when the pressing handle 3 abuts against the first limit table 204, it can effectively prevent the pressing handle 3 from moving further downward, and the structure can remain stable even under the action of a large external force, preventing the pressing column 4 from continuing to penetrate due to excessive operating force, thereby preventing damage to the circuit board.

[0042] A protrusion 501 is provided at one end of the stepped screw rod 5 away from the pressing handle 3 , and the protrusion 501 is exposed outside the corresponding limiting opening 203 .

[0043] In this embodiment, when the protrusion 501 abuts against the limiting opening 203 , the pressing handle 3 is in a stationary state. Further, the step screw 5 and the protrusion 501 are configured to form an inverted T-shaped structure, which is used to prevent the pressing column 4 from being separated from the limiting opening 203 .

[0044] The limiting opening 203 is provided with a second limiting platform 205 for contacting or separating with the protrusion 501 .

[0045] In this embodiment, when the second limiting table 205 is in contact with the protrusion 501, it can jointly bear and disperse the lateral force and longitudinal force generated by pressing, prevent wear or loosening caused by long-term use or strong pressing, and extend the service life. At the same time, the second limiting table 205 can also partially close the limiting opening 203, play a certain protective role, reduce external pollutants such as dust and moisture from entering the installation bin 101, and protect the internal structure from damage.

[0046] One end of the step screw rod 5 close to the pressing handle 3 is threadedly penetrated through the pressing handle 3 and is threadedly provided with a nut 7 ; the pressing handle 3 is provided with a plurality of through holes 8 for accommodating the step screw rods 5 .

[0047] In this embodiment, a plurality of through holes 8 are provided on the pressing handle 3 for the step screw 5 to pass through, and are locked by a nut 7 so as to fix the pressing handle 3, the spring 6 and the step screw 5 together. When the pressing handle 3 drives the pressing column 4 to extend into the installation bin 101, the step screw 5 is linked by the spring 6 to extend therein. The step screw 5 is coaxially spaced apart from the pressing column 4 so as to guide the moving path of the pressing column 4.

[0048] The pressing column 4 is provided with a plurality of reinforcing ribs 9 in the length direction thereof.

[0049] In this embodiment, the reinforcing ribs 9 can significantly improve the bending and torsional strength of the pressing column 4 .

[0050] The plurality of reinforcing ribs 9 converge to one end of the pressing column 4 away from the pressing handle 3 and form an inclined surface 10 .

[0051] In this embodiment, the inclined surface 10 helps to distribute the pressing force more evenly along the length direction of the pressing column 4, avoiding excessive pressure on local areas, making the entire pressing column 4 perform more evenly when subjected to force, and improving the smoothness of the pressing operation. At the same time, in order to improve the performance of the pressing column 4, the lower end of the pressing column 4 forms a tip-like shape to facilitate contact with the circuit board button.

[0052] This embodiment also provides an air conditioner, including a PCB assembly 11, provided with an emergency switch button; and

[0053] As described above, in the emergency switch pressing structure, the mounting compartment 101 is provided with a plurality of mounting points for fixing the PCB assembly 11, and the pressing column 4 is suspended above the emergency switch button.

[0054] In this embodiment, the PCB assembly 11 is installed in the installation bin 101, and the pressing column 4 is suspended above the emergency switch button, ensuring that the emergency power-off command can be quickly and directly transmitted to the switch button contact on the PCB assembly 11 through mechanical transmission, reducing intermediate links, and improving response speed and reliability. The installation bin 101 is provided with a plurality of installation points for fixing the PCB assembly 11, which is convenient for quickly positioning and fixing the PCB assembly 11 during production and assembly, and also provides convenience for later maintenance and troubleshooting, reducing the difficulty and time cost of maintenance.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
