Description

Technical Field

[0001] The present invention relates to the technical field of clothes drying machine structures, and in particular to a linear contact resistance mechanism, a power integration module and a clothes drying machine. Background Art

[0002] At present, since smart clothes drying machines can realize functions such as lifting, drying, and disinfecting, they are gradually accepted by the majority of users and widely used in every household; however, since the clothes drying machine can drive the clothes drying rod to move up and down, if the user stands under the clothes drying machine, the descending clothes drying rod can easily hit the user's head, posing a certain safety hazard.

[0003] In order to solve the above-mentioned safety problem, clothes drying machines on the market are provided with an obstruction mechanism, which can detect whether the clothes drying rod collides with other objects during its descent. The existing obstruction mechanism generally uses sensors and springs to detect the state of the winding assembly; however, since the spring has a certain extension and contraction range, the obstruction mechanism using sensors and springs to cooperate with each other is relatively large in size.

[0004] And the existing resistance mechanism is generally installed on the winding assembly, and determines whether the current clothes-drying rod encounters resistance by indirectly detecting the movement state of the rotating shaft on the winding assembly or the slider linked to the steel wire. In actual situations, if the clothes-drying rod encounters resistance during the lifting process, the tightness of the steel wire will be changed directly and first. However, if the movement state of the rotating shaft or the slider is detected as mentioned above, the accuracy and timeliness of the detection will be relatively poor, and the clothes-drying rod cannot be controlled to stop moving in the first time, and there are still safety hazards.

[0005] In addition, some resistance mechanisms cannot detect whether the current steel wire is in a relaxed state, so that when the winding assembly is just started, the steel wire needs to be tightened before the clothes-drying rod can be driven up and down, which makes the movement of the clothes-drying rod have a certain delay, making the user experience poor. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art, one of the purposes of the present invention is to provide a linear touch resistance mechanism to replace the traditional solution of using a spring, reduce the volume of the resistance mechanism, and at the same time use the wire pressing part to directly press the steel wire to improve the accuracy and timeliness of detection.

[0007] The second object of the present invention is to provide a power integration module, which integrates the resistance mechanism and other parts of the clothes drying machine into a box body, so that the wiring of the parts is neat and easy to install and disassemble.

[0008] The third object of the present invention is to provide a clothes drying machine, in which a box body integrated with an obstacle mechanism and other parts of the clothes drying machine is installed on a bottom plate of the clothes drying machine, thereby saving internal space of the clothes drying machine.

[0009] One of the purposes of the present invention is achieved by the following technical solution:

[0010] A body member having a side wall;

[0011] A switch spring is connected to the side wall and is provided with a contact portion connected to the wire of the main body within the deformation range of the switch spring, so that the switch spring presses or releases the contact portion when elastic deformation occurs;

[0012] The pressing member includes a supporting rod and a wire pressing portion, wherein the front and rear ends of the supporting rod have overlapping projections on the vertical plane where the side wall is located; the supporting rod is connected to the side of the wire pressing portion facing the main body; the wire pressing portion drives the supporting rod to move toward the direction of the main body under the action of external force, so as to support the switch spring sheet, cause it to undergo elastic deformation and press against the contact portion to realize conduction of the main body.

[0013] Furthermore, one end of the switch spring is connected to the side wall of the main body, and the other end is not connected to the side wall of the main body, so that an angle is formed between the switch spring and the side wall of the main body, and the contact portion is arranged on the side wall of the main body within the range of the angle.

[0014] Furthermore, the included angle between the switch spring and the side wall of the main body is 20° to 60°.

[0015] Furthermore, relative to an end of the switch spring piece that is not connected to the side wall of the main body, the contact portion is closer to an end of the switch spring piece that is connected to the side wall of the main body.

[0016] Furthermore, the wire pressing part includes a fixing frame and a roller, and two ends of the roller are pivotally connected to the fixing frame; and the orthographic projection area of ​​the roller on the horizontal plane is the same as the bottom area of ​​the roller.

[0017] Furthermore, there is a gap between the bottom edge of the fixing frame and the roller, and an inclined notch is provided on the bottom edge of the fixing frame, so that the length of the notch is greater than the width of the bottom edge.

[0018] The second object of the present invention is achieved by adopting the following technical solution:

[0019] A power integration module, comprising:

[0020] The box body comprises a bottom plate and a surrounding plate, and the two together define a containing space; the surrounding plate is non-enclosedly surrounded to form an open opening, and cavities are respectively provided on the box body at both sides of the open opening;

[0021] A main control board, arranged in the accommodation space and connected to the bottom plate;

[0022] A winding device is located at the opening and connected to the bottom plate and connected to the main control board wires; the outlet of the winding device is exposed outside the box;

[0023] As mentioned above, the straight line touch resistance mechanism is fixed in the cavity, and the main body is connected to the wires of the main control board; the wire pressing part is exposed outside the cavity and is located in the wire outlet direction of the wire outlet, so that the steel wire led out of the wire outlet of the winding device passes through the wire pressing part; when the steel wire is in a taut state, the steel wire presses against the wire pressing part so that the supporting rod supports the switch spring piece and presses toward the contact part.

[0024] Furthermore, a locking groove is provided in the cavity at a position corresponding to the supporting rod, and a protrusion corresponding to the locking groove is provided on the surface of the supporting rod facing the cavity, so that the protrusion of the supporting rod slides relative to the locking groove.

[0025] Furthermore, when the steel wire is in a taut state, the steel wire is led out from the wire outlet of the winding device in a tangential direction and presses against the wire pressing portion, and the steel wire and the long side of the bottom plate are parallel to each other.

[0026] The third object of the present invention is achieved by adopting the following technical solution:

[0028] The host is provided with a bottom panel;

[0029] As in the above-mentioned power integration module, the box body is reversely mounted on the bottom panel so that the bottom panel shields the accommodation space.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The method of using a pressure piece to hold and trigger the main body part replaces the traditional solution of using a spring, thereby reducing the volume of the resistance mechanism. At the same time, the wire pressing part is used to directly press the steel wire. When the steel wire is loose or broken, the steel wire cannot provide sufficient force to press the wire pressing part, which will cause the pressure piece to separate from the main body to achieve an emergency stop of the winding device, thereby improving the accuracy and timeliness of the detection.

DETAILED DESCRIPTION

[0041] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0042] Embodiment 1

[0043] This embodiment provides a linear touch resistance mechanism 4, which eliminates the original elastic reset element such as a spring, and relies on the switch spring 42 on the main body 41 to reset to achieve the purpose of emergency stop when encountering resistance, thereby reducing the overall volume of the resistance mechanism 4.

[0044] like Figure 1As shown, the linear touch resistance mechanism 4 in this embodiment includes a main body 41, and a switch spring 42 is provided on any side wall of the main body 41. The switch spring 42 has a certain elasticity relative to the main body 41 and can be elastically deformed under external force. The switch spring 42 can be cut from the side of the main body 41 close to the edge, or the switch spring 42 can be detachably installed on one side wall of the main body 41, so that one end of the switch spring 42 is detachably connected to the main body 41, and the other end of the switch spring 42 is also not connected to the main body 41, so that the switch spring 42 and the side wall of the main body 41 form an angle of 20° to 60°; when the switch spring 42 is pressed by external force, the switch spring 42 can move in the direction of the side wall of the main body 41 and deform, and when the external force disappears, the switch spring 42 can restore the deformation and move in the direction away from the side wall of the main body 41.

[0045] A contact portion 43 is provided at the position where the switch spring piece 42 passes during the elastic deformation of the switch spring piece 42, and the contact portion 43 is connected to the main circuit inside the body member 41. In this embodiment, the contact portion 43 is provided on the side wall of the body member 41 facing the switch spring piece 42, and the contact portion 43 falls within the angle range between the switch spring piece 42 and the body member 41, so that the switch spring piece 42 can touch and press the contact portion 43 during the deformation process, thereby triggering the main circuit inside the body member 41 to be turned on; when the switch spring piece 42 is away from the contact portion 43, the main circuit inside the body member 41 is disconnected.

[0046] In this embodiment, the contact portion 43 is closer to the end of the switch spring piece 42 that is not connected to the side wall of the main body 41, relative to the end of the switch spring piece 42 that is not connected to the side wall of the main body 41, so that the distance between the contact portion 43 and the switch spring piece 42 becomes closer, so that when the switch spring piece 42 is slightly displaced, the contact portion 43 can also immediately detect the movement of the switch spring piece 42, making the detection process more accurate.

[0047] A pressure piece is provided below the main body 41, and the pressure piece includes a supporting rod 44 and a pressing portion. In the present embodiment, the projections of the head and tail ends of the supporting rod 44 on the vertical plane where the side wall of the main body 41 is located completely overlap, that is, the supporting rod 44 is a straight rod.

[0048] One end of the abutting rod 44 is used to abut the switch spring 42 to deform the switch spring 42 so that it presses the contact portion 43, and one end of the abutting rod 44 is connected to the wire pressing portion. In this embodiment, the wire pressing portion can drive the abutting rod 44 to move in the direction of the main body 41 under the action of external force, so that the end of the abutting rod 44 abuts the switch spring 42 to elastically deform it and press it toward the contact portion 43, so that the switch spring 42 and the contact portion 43 are in contact with each other, so that the main body 41 is turned on; when there is no external force, the end of the abutting rod 44 of the wire pressing portion is separated from the switch spring 42, or the two are in contact but there is no interaction force, so that the switch spring 42 does not elastically deform and does not contact the contact portion 43, so that the main body 41 is not turned on.

[0049] In this embodiment, the wire pressing part includes a fixed frame 45 and a roller 46. The fixed frame 45 is set as a hollow four-frame structure, and the two ends of the roller 46 are pivoted on the fixed frame 45, so that the roller 46 can rotate in the fixed frame 45. The roller 46 is set as a cylindrical structure, and the orthographic projection area of ​​the roller 46 on the horizontal plane is the same as the bottom area of ​​the roller 46, and the orthographic projection of the roller 46 on the vertical plane where the side wall is located coincides with the orthographic projection of the supporting rod 44 on the vertical plane where the side wall is located. At the same time, there is a gap between the bottom edge of the fixed frame 45 and the roller 46, so that the gap can be used to accommodate objects of the clothes drying machine steel wire. When the obstruction mechanism 4 is used in the clothes drying machine, the clothes drying machine steel wire in a taut state presses the roller 46, and the rotatable roller 46 avoids affecting the normal retracting and releasing action of the steel wire, while reducing the friction between the roller 46 and the steel wire.

[0050] like Figure 4 As shown, after the wire pressing part is pushed by the taut steel wire, the wire pressing part drives the supporting rod 44 to move toward the main body 41, and the switch spring 42 presses the contact part 43, so that the main body 41 is turned on, and the clothes drying machine can be kept running normally; when the steel wire is loose or disconnected, the steel wire cannot provide enough thrust for the wire pressing part, so that the external force disappears, and the switch spring 42 gradually moves away from the contact part 43 during the elastic deformation recovery process, so that the main body 41 is not turned on, and the clothes drying machine can stop running. The wire pressing part can directly and accurately detect the state of the steel wire, which improves the detection accuracy of the resistance mechanism 4.

[0051] In addition, an inclined notch 47 is provided on the bottom edge of the fixing frame 45, and the steel wire enters into the gap between the fixing frame 45 and the roller 46 through the notch 47, so as to achieve the effect of the steel wire pressing against the roller 46; and the notch 47 is set to an inclined state, that is, the length of the notch 47 is greater than the width of the bottom edge, so that the steel wire in the taut state is not parallel to the notch 47, thereby preventing the steel wire from easily falling out of the notch 47 and affecting the normal operation of the resistance mechanism 4.

[0052] Embodiment 2

[0053] The present embodiment provides a power integration module, which integrates the main control board 2, the resistance mechanism 4 and the winding device 3 on a box body 1, so that the structure of the power integration module is more compact, the internal wiring is neat and orderly, and the safety hazards are eliminated while speeding up the efficiency of disassembly and assembly and improving the internal aesthetics.

[0054] like Figure 2 to Figure 7 As shown, the power integration module of this embodiment includes a box body 1 and a main control board 2 installed on the box body 1, a winding device 3 and the obstruction mechanism 4 in the first embodiment. The box body 1 includes a bottom plate 11 and a surrounding plate 12, and the surrounding plate 12 is vertically connected to the edge of the bottom plate 11, so that the two together define a storage space, and the storage space can be used to accommodate the main control board 2 and other components, so that the components are concentrated in the box body 1, and the wiring is neat. In this embodiment, the bottom plate 11 is set to a rectangular structure, so that the box body 1 formed by surrounding becomes a box structure.

[0055] The surrounding plate 12 includes two short side walls 121 and one long side wall 122, the two short side walls 121 are relatively connected at the short side edges at both ends of the bottom plate 11, and the long side wall 122 is connected at any long side edge of the bottom plate 11, and the two ends of the long side wall 122 are respectively connected to the two short side walls 121, and the surrounding plate 12 is non-closed to form an open opening, which is used to set the winding device 3, and a certain gap is retained between the open opening and the lower edge line of the box body 1, that is, the winding device 3 is closer to the upper edge line of the box body 1, so that when the power integration module is reversely installed on the bottom panel 5 of the clothes drying machine host, the surface of the winding device 3 can be close to the bottom panel 5, which is convenient for fixing the bottom panel 5 and the winding device 3.

[0056] A main control board 2 is arranged in the accommodation space, and the main control board 2 is connected to the bottom plate 11. A plurality of padding blocks 13 are arranged at the bottom of the bottom plate 11, and the padding blocks 13 can be set as a cylinder fixed on the bottom plate 11, or a protrusion fixed below the long side wall 122, or a reinforcing rib on the bottom plate 11, and the reinforcing rib spans the bottom plate 11, and protrusions are arranged at both ends of the reinforcing rib; so that the main control board 2 is placed on the bottom plate 11, and the side of the main control board 2 facing the bottom plate 11 is padded by the padding blocks 13, so that a certain gap is maintained between the main control board 2 and the bottom plate 11, so as to avoid the components on the main control board 2 directly contacting the bottom plate 11 and affecting the resistance of the components, and at the same time, it is also convenient for the main control board 2 to dissipate heat, so that air can pass through the gap between the main control board 2 and the bottom plate 11 to take away the heat generated by the main control board 2.

[0057] A wire opening 14 is provided on both short side walls 121, and the wire opening 14 is located below the short side walls 121, but the wire opening 14 is kept from contacting the upper edge and the lower edge of the short side walls 121. When the main control board 2 is placed in the box body 1, the power lines of various functional devices in the clothes drying machine are connected to the main control board 2 after passing through the wire opening 14, so that the internal wiring is neat and orderly, and safety accidents are avoided.

[0058] In this embodiment, the winding device 3 includes a shell 31, a winding group 32 and a motor 34 linked to the winding group 32, wherein the motor 34 can be connected to the main control board 2, and the movement state of the motor 34 is controlled by the main control board 2; one end of the shell 31 is connected to the bottom plate 11 of the box body 1, so that the winding device 3 is fixed on the bottom plate 11, and at the same time, the shell 31 extends to the outside of the box body 1 through the open mouth, so that the motor 34 can be set at a position outside the box body 1 without being limited by the limited space of the box body 1.

[0059] The side of the shell 31 facing the bottom plate 11 is inwardly recessed with two hollow cylinders 311, and a winding group 32 is provided in each of the two hollow cylinders 311, and an outlet 312 is provided at the outer end of each hollow cylinder 311; the orthographic projection of the outlet 312 on the horizontal plane does not coincide with the orthographic projection of the box body 1 on the horizontal plane, that is, the outlet 312 is exposed outside the box body 1. In the present embodiment, the winding group 32 includes a rotating shaft provided on the hollow cylinder 311 and a steel wire wound on the rotating shaft, and the steel wire is led out from the outlet 312 along the tangent direction of the rotating shaft.

[0060] A card interface 33 is provided on one side of the shell 31 facing the long side wall 122, and the orthographic projection of the card interface 33 on the horizontal plane does not overlap with the orthographic projection of the box body 1 on the horizontal plane. The card interface 33 is connected to the motor 34 so that the motor 34 is exposed outside the box body 1; and the motor 34 is linked with the winding group 32. When the motor 34 rotates, it can drive the winding group 32 to rotate clockwise or counterclockwise, so as to pull the steel wire out or retract it into the winding group 32, and drive the clothes-drying rod to complete the rising or falling action.

[0061] Even though the motor 34 is exposed outside the box body 1, the motor 34 is connected to the housing 31, and one end of the housing 31 is connected to the bottom plate 11, so the motor 34 and the box body 1 can still be disassembled and assembled synchronously.

[0062] like Figure 3 As shown, the winding device 3 is distributed on the center line A of the box body 1. Specifically, the two winding groups 32 are respectively located on the left and right sides of the center line A of the box body 1, and the motor 34 is located on the center line A of the box body 1, so that the power integration module has a left-right symmetrical structure.

[0063] At the same time, the height of the positive projection of the winding device 3 on the long side wall 122 is less than or equal to the height of the long side wall 122, that is, the overall height of the shell 31 and the motor 34 installed on the shell 31 is less than or equal to the height of the long side wall 122, so that when the box body 1 is reversely installed on the bottom panel 5 of the clothes drying machine, the winding device 3 will not protrude outside the box body 1, causing the box body 1 to be unable to be tightly installed on the bottom panel 5 of the clothes drying machine, and at the same time, the overall volume of the power integration module is relatively small, the structure is compact and the degree of integration is high.

[0064] At the same time, cavities 16 extend outward from the box body 1 on both sides of the open mouth. The cavity 16 is used to install the obstruction mechanism 4 in the first embodiment. The obstruction mechanism 4 determines whether the steel wire is broken or whether the clothes drying rod encounters an obstacle by detecting whether the steel wire is in a relaxed state. The specific structure of the obstruction mechanism 4 has been described in the first embodiment and will not be described in detail here. The obstruction mechanism 4 is fixed in the cavity 16, and the main body 41 is connected to the main control board 2 by wires. The main control board 2 can timely know the on and off status of the main body 41 and control the clothes drying machine to perform corresponding operations.

[0065] In this embodiment, a locking groove 161 is provided in the cavity 16 at a position corresponding to the retaining rod 44, and a protrusion 441 corresponding to the locking groove 161 is provided on the surface of the retaining rod 44 facing the cavity 16, so that the protrusion 441 of the retaining rod 44 slides relative to the locking groove 161 to ensure that the retaining rod 44 always moves back and forth along the locking groove 161, thereby preventing the retaining rod 44 from shifting and affecting the detection accuracy.

[0066] The wire pressing portion is exposed outside the cavity 16 and is located in the wire outlet direction of the wire outlet 312, so that the steel wire led out of the wire outlet 312 of the winding device 3 passes through the gap between the roller 46 and the bottom edge of the fixing frame 45; when the steel wire is in a taut state, the steel wire is led out from the wire outlet 312 of the winding device 3 in a tangential direction and presses against the roller 46, and the steel wire is parallel to the long side of the bottom plate 11, thereby improving the stability of the steel wire movement.

[0067] Embodiment 3

[0068] This embodiment provides a clothes drying machine, such as Figure 8 As shown, it includes a clothes drying machine host and a power integration module as described in the second embodiment; the host is provided with a bottom panel 5, and the box body 1 is reversely mounted on the bottom panel 5, so that the bottom panel 5 blocks the accommodation space. At the same time, in order to realize the installation of the box body 1 on the bottom panel 5 of the clothes drying machine host, at least one side wall fixing hole 15 extending outward is provided on each of the short side walls 121, and the side wall fixing hole 15 does not contact the bottom plate 11, that is, the side wall fixing hole 15 can be set on the upper edge line of the short side wall 121, or can be set in the middle of the short side wall 121, but always maintains a certain distance from the bottom plate 11, so that when the box body 1 is installed on the bottom panel 5 of the clothes drying machine, the accommodation space is directly opposite to the bottom panel 5 of the clothes drying machine, and the side wall fixing hole 15 is close to or close to the bottom panel 5 of the clothes drying machine, and then the box body 1 can be fixed on the bottom panel 5 of the clothes drying machine by passing the bolts through the screw holes on the bottom panel 5 of the clothes drying machine and the side wall fixing holes 15.

[0069] The long side of the bottom plate 11 is parallel to the long side of the bottom panel 5, and the power integration module is arranged on the center line of the bottom panel 5, so that the two ends of the steel wires led out from the winding group 32 are evenly led out from the two ends of the bottom panel 5 of the clothes drying machine, and the two ends of the steel wires extend to the bottom of the clothes drying machine main body and are connected to the clothes drying rod, thereby driving the clothes drying rod to rise and fall.

[0070] Installing the power integration module integrating the main control board 2, the obstruction mechanism 4 and the winding device 3 in the clothes drying machine can save the internal space of the clothes drying machine, make the lines in the clothes drying machine more orderly and tidy, improve the aesthetics of the interior of the clothes drying machine, and avoid the maintenance efficiency being unable to be improved due to distinguishing messy wires during the maintenance process.

[0071] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
