Description

Technical Field

[0001] This utility model relates to the field of portable air conditioning technology, specifically a controller with a protective structure for portable air conditioners. Background Technology

[0002] Portable air conditioners are small, box-like structures with an air outlet at the top, an air inlet at the rear, a control panel at the front, and casters at the bottom. They contain electrical components for cooling and heating, as well as a controller for function control. Portable air conditioners are advantageous due to their small size, light weight, and good mobility. However, they may tip over during transport or in the event of an accidental impact. When tipped over, the entire unit can easily collide with the ground, damaging the built-in controller and reducing its lifespan.

[0003] Currently, the controller used in portable air conditioners is a separate product, consisting of a housing and a circuit board inside the housing. When the controller is assembled with the portable air conditioner, it is usually fixed to the side wall inside the housing of the portable air conditioner with screws. In other words, the entire controller and the portable air conditioner are in a rigid connection state. This rigid connection structure makes the circuit board inside the controller easily damaged by impact.

[0004] Therefore, this utility model provides a controller with a protective structure for a portable air conditioner. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a controller with a protective structure for portable air conditioners, so as to solve the problems mentioned in the background art. This utility model has the advantage of improving the impact resistance of the controller and greatly extending the service life of the controller adapted to portable air conditioners.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a controller with a protective structure for a portable air conditioner, comprising a controller body, the controller body including a square outer shell and a protective frame, the square outer shell being housed within the protective frame, and shock-absorbing support mechanisms located at four positions between the square outer shell and the protective frame, the shock-absorbing support mechanism including a positioning plate, diagonal braces, and an elastic structure, one side of the positioning plate being connected to the side wall of the square outer shell, the other side of the positioning plate being rotatably connected to one end of two diagonal braces, an elastic structure being provided between the two diagonal braces, and the other end of the two diagonal braces being in rolling engagement with one side of the protective frame.

[0007] Furthermore, the other end of the diagonal brace is connected to a support shaft, the inner side of the protective frame is provided with a V-shaped groove, and both ends of the support shaft are fitted with V-shaped rollers that roll in cooperation with the V-shaped groove.

[0008] Furthermore, the other end of the diagonal brace is fixedly connected to a guide sleeve sleeved outside the support shaft. The guide sleeve and the support shaft are slidably connected. A stop plate located on one side of the V-shaped roller and abutting against one end of the return spring is fixedly sleeved on the support shaft.

[0009] Furthermore, the guide sleeve has an annular groove near both ends, and a rubber sleeve is nested in the annular groove.

[0010] Furthermore, the elastic structure includes a transmission plate, a gear, and a buffer spring. One end of the diagonal brace is fixedly connected to a positioning shaft that is rotatably connected to the positioning plate. A gear is fixedly sleeved on the positioning shaft. The transmission plate is located between the two diagonal braces and meshes with the gear. The transmission plate and the positioning plate are slidably connected, and a buffer spring is provided between them.

[0011] Furthermore, a grooved plate is welded to one side of the positioning plate, a limit sleeve is welded to the blind end of the grooved plate, a rubber sleeve II is fixedly fitted inside the limit sleeve and fitted outside the transmission plate, a buffer spring is fitted outside the transmission plate and one end of the buffer spring abuts against the inner side of the blind end of the grooved plate, and a baffle is fixedly fitted on the transmission plate and abuts against the other end of the buffer spring.

[0012] Furthermore, a mounting plate is welded to one end of the protective frame, and a mounting hole is provided on one side of the mounting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a protective frame is fixedly connected to one side of the portable air conditioner housing and the inner wall of the housing. Then, the controller body is placed inside the protective frame. The controller body includes a square outer shell. A shock-absorbing support mechanism is provided between the four sides of the square outer shell and the protective frame. The shock-absorbing support mechanism can buffer the upward impact force applied to the controller body when the portable air conditioner is dropped to the side, thereby effectively protecting the controller body and extending the service life of the controller body.

[0015] 2. In this utility model, the shock-absorbing support mechanism includes two diagonal braces, two gears, a transmission plate, and a shock-absorbing spring. One end of the diagonal brace is equipped with a V-shaped roller. Therefore, under the meshing cooperation of the two gears and the transmission plate, the two diagonal braces have the function of synchronous swinging. This function makes the entire controller body move regularly when it is subjected to impact. Then, under the rolling guidance of the V-shaped roller, the buffer displacement action of the controller body is smoother and there will be no problem of motion jamming, making it more reliable and practical.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a controller with a protective structure for a portable air conditioner, including a controller body, the controller body including a square shell 1, the square shell 1 housing a circuit board assembly for control, and ventilation holes and wire holes on the outer wall of the square shell 1. In the prior art, the square shell 1 is installed on the side wall inside the portable air conditioner casing by bolts, but this hard connection method will reduce the impact resistance of the circuit board assembly inside the controller body.

[0023] In this technical solution, a protective frame 2 is added, and the square outer shell 1 is housed in the protective frame 2. The protective frame 2 is a square frame plate structure. Shock-absorbing support mechanisms are provided between the square outer shell 1 and the protective frame 2 at four different locations. Specifically, each of the four sides of the square outer shell 1 corresponds to a shock-absorbing support mechanism. The purpose is to buffer the impact force caused by the side drop of the mobile air conditioner and avoid damage to the circuit board assembly inside the controller body.

[0024] Specifically, the shock-absorbing support mechanism includes a positioning plate 3, diagonal braces 4, and an elastic structure 5. One side of the positioning plate 3 is connected to the side wall of the square outer shell 1. Preferably, the positioning plate 3 has a through hole, and the side wall of the square outer shell 1 has screw holes. The positioning plate 3 is fastened to the side wall of the square outer shell 1 through the cooperation of screws, through holes, and screw holes. This arrangement facilitates the assembly and disassembly of the positioning plate 3 and the square outer shell 1. The other side of the positioning plate 3 is rotatably connected to one end of the two diagonal braces 4. An elastic structure 5 is provided between the two diagonal braces 4. The two diagonal braces 4 on the positioning plate 3 form a figure-eight shape. The elastic structure 5 keeps the various shock-absorbing support mechanisms and the inner side wall of the protective frame 2 under elastic compression. The other end of the two diagonal braces 4 is in rolling cooperation with one side of the inner side of the protective frame 2. In this state, the included angle between the two diagonal braces 4 is between 110° and 120°, which is the optimal support angle. When the portable air conditioner is dropped to the side, the aforementioned rolling mechanism allows the controller body, along with its surrounding shock-absorbing support mechanism, to perform adaptive buffering movements in four directions. This greatly reduces the impact force of the portable air conditioner dropping to the circuit board assembly inside the controller body. It should be noted that when the portable air conditioner is dropped to the side, the controller body experiences significant vertical impact forces.

[0025] The elastic structure 5 includes a transmission plate 51, a gear 52, and a buffer spring 53. One end of the diagonal brace 4 is fixedly connected to a positioning shaft 42 that is rotatably connected to the positioning plate 3. Specifically, two hinge seats are welded to one side of the positioning plate 3, and the hinge seats are rotatably connected to the positioning shaft 42. The gear 52 is fixedly sleeved on the positioning shaft 42. The transmission plate 51 is located between the two diagonal braces 4 and meshes with the gear 52. Specifically, teeth that mesh with the gear 52 are fixedly provided on both sides of the transmission plate 51. The transmission plate 51 and the positioning plate 3 are slidably connected, and a buffer spring 53 is provided between them. Specifically, the buffer spring 53 is sleeved on the outside of the transmission plate 51, and one end of it abuts against the inner side of the blind end of the groove plate 31. A baffle 511 that abuts against the other end of the buffer spring 53 is fixedly sleeved on the transmission plate 51. The buffer spring 53 applies an elastic thrust to the transmission plate 51 through the baffle 511, causing the transmission plate 51 to tend to move toward the positioning plate 3. Under this tendency, the two diagonal braces 4 have a tendency to swing in opposite directions.

[0026] Furthermore, a grooved plate 31 is welded to one side of the positioning plate 3, and a limit sleeve 311 is welded to the blind end of the grooved plate 31. A rubber sleeve 7 is fixedly fitted inside the limit sleeve 311 and is fitted on the outside of the transmission plate 51. The inner wall of the rubber sleeve 7 fits against the outer wall of the transmission plate 51. The rubber sleeve 7 increases the sliding resistance of the transmission plate 51, so that the entire controller body can quickly return to a stable state after being impacted.

[0027] In this embodiment, the diagonal brace 4 and the protective frame 2 are in a rolling cooperation manner. The other end of the diagonal brace 4 is connected to the support shaft 6. The inner side of the protective frame 2 is provided with a V-shaped groove 21. Both ends of the support shaft 6 are fitted with V-shaped rollers 61 that roll with the V-shaped groove 21. One V-shaped roller 61 corresponds to one V-shaped groove 21. The two inclined surfaces on the V-shaped roller 61 abut against the two inclined surfaces in the V-shaped groove 21 respectively. This abutment effect comes from the elastic structure 5. This arrangement can effectively avoid the problem of the V-shaped roller 61 rolling and getting stuck in the V-shaped groove 21. Therefore, when the mobile air conditioner is dropped and hits the ground, each shock-absorbing support mechanism will adapt to the action, and the V-shaped roller 61 will adapt to roll along the V-shaped groove 21.

[0028] Furthermore, the other end of the diagonal brace 4 is fixedly connected to a guide sleeve 41 sleeved on the outside of the support shaft 6. The guide sleeve 41 and the support shaft 6 are slidably connected. The support shaft 6 is fitted with return springs 8 located on both sides of the guide sleeve 41. The support shaft 6 is fixedly fitted with a baffle 62 located on one side of the V-shaped roller 61 and abutting against one end of the return spring 8. When the portable air conditioner is thrown to the side, it will generate a lateral impact force on the entire controller body. That is to say, after the portable air conditioner is thrown to the side, it is in a horizontal state, while the controller body is in an upright state. When the impact force hits the controller body in the upright state, the guide sleeve 41, return spring 8 and baffle 62 set above will cause the support shaft 6 to move axially, and the return spring 8 will extend and retract. This can absorb the lateral impact force received by the controller body after being thrown to the side. Among them, annular grooves 411 near both ends can be opened in the guide sleeve 41. A rubber sleeve 9 is nested in the annular groove 411. The function of the rubber sleeve 9 is to increase the resistance of the support shaft 6 sliding relative to the guide sleeve 41, and the purpose is also to make the controller body quickly return to a stable state after being impacted.

[0029] In this embodiment, a mounting plate 22 is welded to one end of the protective frame 2. A mounting hole 221 is provided on one side of the mounting plate 22. When in use, the protective frame 2 is fixedly installed on a side wall inside the portable air conditioner housing by the mounting plate 22 and screws. At this time, the controller body is in a horizontal state.

[0030] Working principle: When the portable air conditioner falls to its side and hits the ground, the horizontally positioned portable air conditioner will exert an upward inertial impact force on the protective frame 2. Under this impact force, the shock-absorbing support mechanism above and below the current square outer shell 1 will move significantly. For example, the two diagonal braces 4 in the lower shock-absorbing support mechanism will swing outward, and the V-shaped roller 61 will roll along the V-shaped groove 21. The two diagonal braces 4 will drive the two gears 52 fixedly connected to them to rotate synchronously in opposite directions. The gears 52 drive the transmission plate 51 to move downward, and the baffle 511 moves downward and squeezes the buffer spring 53. The buffer spring 53 is compressed. At this time, the entire controller body will slowly descend relative to the protective frame 2, thereby resisting the upward impact force of the portable air conditioner falling to its side on the controller body.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
