Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to an electric turning clothes hanger. Background Art

[0002] With the continuous development of modern life and the improvement of people's quality of life, the requirements for household storage and clothing hanging are getting higher and higher. Traditional clothes hangers can no longer meet people's needs for storage and hanging. Therefore, electric flip hangers have emerged as a new type of home product. Traditional clothes hangers are usually fixed and cannot be adjusted according to needs. They are not convenient for hanging clothes at different heights. At the same time, the load-bearing capacity of traditional clothes hangers is limited, and they are easily bent or broken due to gravity. As a high-tech home product, the electric flip hanger can solve these problems with its unique adjustable height and adjustable width.

[0003] Existing electric flip hangers, such as Chinese patent publication No. CN213524412U, disclose a lifting hanger and a cabinet, in which the motor is installed vertically, which causes the entire housing to extend downward, resulting in a waste of space in the cabinet in the height direction. Utility Model Content

[0004] The utility model aims to provide an electric turning clothes hanger, which can effectively solve the problem that the shell of the existing electric turning clothes hanger occupies too much lower space and causes waste.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The electric turning clothes hanger comprises two turning power members and a clothes hanger rod, wherein the turning power members comprise:

[0007] A shell, wherein the shell is disposed horizontally;

[0008] A motor, fixed in the housing and electrically connected to a control unit;

[0009] a linear telescopic member connected to a pin that moves linearly along the length of the housing; and,

[0010] Curved arm with slide;

[0011] The hanger rod is arranged between the crank arms of the two flip power parts, the linear telescopic component is transmission-connected with the motor, the pin shaft is slidingly connected with the slide groove, and the motor drives the crank arm to rotate through the linear telescopic component, thereby driving the hanger rod to swing back and forth.

[0012] In the above-mentioned electric flip hanger, the crank arm includes a swing part and a transmission part, the angle between the swing part and the transmission part is an acute angle or an obtuse angle, the hanger rod is connected to the swing part, and the slide groove is provided in the transmission part.

[0013] In the above-mentioned electric flip clothes hanger, the linear telescopic component is a screw assembly, which includes a screw body and a transmission member threadedly connected to the screw body, the transmission member is connected to the pin shaft, and the motor is transmission-connected to the screw body.

[0014] In the above-mentioned electric flip hanger, the horizontal height of the motor is higher than the horizontal height of the linear telescopic component, and the motor and the linear telescopic component are connected via a worm gear transmission.

[0015] In the above-mentioned electric flip hanger, a distance sensor electrically connected to the control unit is provided on the crank arm to detect the distance to the object in front when the hanger rod swings.

[0016] In the above-mentioned electric flip hanger, the distance sensor is located at the end where the curved arm is connected to the hanger rod, and faces the direction in which the hanger rod flips downward.

[0017] In the above-mentioned electric flip hanger, a flip switch is provided at the end of the crank arm of at least one flip power member connected to the hanger rod, and the flip switch is electrically connected to the control unit.

[0018] In the above-mentioned electric flip clothes hanger, a resistance sensor is fixed on the curved arm, and the resistance sensor is configured to sense the deformation of the curved arm and generate an electrical signal. The resistance sensor is electrically connected to the control unit.

[0019] In the above-mentioned electric flip hanger, the resistance sensor is a piezoelectric sheet or a strain gauge, which is mounted on the curved arm, and the electrical connection wire between the resistance sensor and the control unit is guided through the inside of the curved arm.

[0020] In the above-mentioned electric flip hanger, the installation position of the resistance sensor on the curved arm is closer to the housing than the hanger rod.

[0021] Compared with the prior art, the advantages of the utility model are:

[0022] By arranging the shell horizontally and providing a linear telescopic component that telescopes along the length direction of the shell, the problem of the shell of the current electric flip hanger occupying too much space below and causing waste is solved. The linear telescopic component is driven by a motor to move, and the linear telescopic component is connected to a pin that moves linearly along the length direction of the shell, so that the entire driving part is arranged along the length direction of the shell, and the shell is arranged horizontally, which reduces the space occupied in the vertical direction of the cabinet, allowing the flip hanger to be as close to the bottom of the cabinet as possible during installation, reducing the height requirement of the electric flip hanger in the cabinet, and electric flip hangers of the same height occupy less space in the height direction. In addition, the linear telescopic component drives the pin shaft to cooperate with the slide groove of the crank arm, thereby driving the crank arm to rotate and realize the reciprocating swing of the hanger rod. This structure can ensure that the position of the motor and the linear telescopic component is fixed relative to the shell while accurately controlling the swing of the hanger rod, thereby avoiding vibration caused by the swing of the motor during the driving process and causing abnormal noise. Moreover, since the hanger rod is driven to swing back and forth by the crank arm, there is also a force arm between the pin shaft and the rotation point of the crank arm. Under the same power, it can have a larger driving torque, so that heavier clothes can be hung on the hanger rod, thereby improving the carrying capacity of the flip hanger.

[0023] Furthermore, the crank arm includes a swing part and a transmission part, the angle between the swing part and the transmission part is an acute angle or an obtuse angle, the hanger rod is connected to the swing part, and the slide groove is provided in the transmission part. The acute angle or the obtuse angle between the swing part and the transmission part is preferably arranged parallel to the length direction of the slide groove, and after the slide groove is provided on the transmission part, the transmission part is kept under uniform force.

[0024] Furthermore, the linear telescopic component is a screw assembly, which includes a screw body and a transmission member threadedly connected to the screw body, the transmission member is connected to the pin, and the motor is connected to the screw body. The linear telescopic is achieved by the screw body and the threaded transmission member, the speed is controllable when the pin is driven to move linearly, and the hanger rod is not prone to setbacks when swinging and runs smoothly.

[0025] Furthermore, the horizontal height of the motor is higher than the horizontal height of the linear telescopic part, and the motor and the linear telescopic part are connected via a worm gear transmission. The arrangement of the motor does not occupy the space below the linear telescopic part, further improving the utilization rate of the space above the linear telescopic part and reducing the height requirement of the electric flip hanger.

[0026] Furthermore, a distance sensor electrically connected to the control unit is provided on the crank arm to detect the distance to the object in front when the hanger rod swings. The distance sensor is used to detect whether there is an obstacle on the swinging path when the hanger rod swings, thereby avoiding the hanger rod from colliding. When the user mistakenly operates the hanger rod to swing, unnecessary damage caused by the hanger rod collision can also be avoided.

[0027] Furthermore, the distance sensor is located at the end of the curved arm connected to the hanger rod, and faces the direction in which the hanger rod flips downward. Setting the distance sensor at the end of the curved arm can more accurately sense and calculate the distance to the obstacle, ensuring that the hanger rod can pass through when flipped. In addition, setting the distance sensor in the direction in which the hanger rod flips downward can prevent the user from accidentally flipping the hanger rod downward and hitting objects such as a cabinet door.

[0028] Furthermore, at least one of the crank arms of the flip power member has a flip switch at the end connected to the hanger rod, and the flip switch is electrically connected to the control unit. By providing a flip switch at the end connected to the crank arm and the hanger rod, the user can easily trigger the flip switch to retract the hanger rod after taking the clothes.

[0029] Furthermore, a resistance sensor is fixed on the crank arm, and the resistance sensor is configured to sense the deformation of the crank arm and generate an electrical signal, and the resistance sensor is electrically connected to the control unit. The deformation degree of the crank arm is detected by the resistance sensor, and when the deformation of the crank arm increases after encountering resistance, the resistance sensor generates an electrical signal to the control unit to stop the motor, thereby protecting the motor from burning and preventing the crank arm from further damage.

[0030] Furthermore, the resistance sensor is a piezoelectric sheet or a strain gauge, which is mounted on the crank arm, and the electrical connection wire between the resistance sensor and the control unit is guided through the inside of the crank arm. The piezoelectric sheet or the strain gauge has a high sensitivity, and can generate an electrical signal when the crank arm has a slight deformation, so as to confirm whether the operation of the crank arm is obstructed early, and the wire is guided from the inside of the crank arm, which increases the safety of the wire and avoids exposure and hanging.

[0031] Furthermore, the installation position of the obstruction sensor on the crank arm is closer to the housing than the hanger rod. The obstruction sensor is located between the obstruction point and the rotation point of the crank arm, which can accurately detect the deformation of the crank arm. The installation position of the obstruction sensor can extend the detection length of the obstruction sensor as much as possible, and can detect obstruction of a wider range of the crank arm.

[0044] The electric flip clothes hanger comprises two flip power members 100 and a hanger rod 200, wherein the flip power member 100 comprises: a shell 110, which is arranged horizontally; a motor 120, which is fixed in the shell 110; a linear telescopic component 130, which is connected to a pin 140 that moves linearly along the length direction of the shell 110; and a curved arm 150, which is provided with a slide groove 160; the hanger rod 200 is arranged between the curved arms 150 of the two flip power members 100, the linear telescopic component 130 is transmission-connected to the motor 120, the pin 140 is slidably connected to the slide groove 160, and the motor 120 drives the curved arm 150 to rotate through the linear telescopic component 130, thereby driving the hanger rod 200 to swing back and forth.

[0045] By placing the housing 110 horizontally and providing a linear telescopic component 130 that telescopes along the length direction of the housing 110, the problem of the housing 110 of the current electric flip hanger occupying too much space below and causing waste is solved. The linear telescopic component 130 is driven to move by the motor 120, and the linear telescopic component 130 is connected to the pin 140 that moves linearly along the length direction of the housing 110, so that the entire driving part is arranged along the length direction of the housing 110, and the housing 110 is arranged horizontally, thus reducing the space occupied in the vertical direction of the cabinet, allowing the flip hanger to be as close to the bottom of the cabinet as possible during installation, reducing the height requirement of the electric flip hanger in the cabinet, and hanging clothes of the same height occupies less space in the height direction. In addition, the linear telescopic component 130 drives the pin 140 to cooperate with the slide groove 160 of the crank arm 150, thereby driving the crank arm 150 to rotate and realize the reciprocating swing of the hanger rod 200. While accurately controlling the swing of the hanger rod 200, this structure can ensure that the motor 120 and the linear telescopic component 130 are fixed relative to the shell 110, thereby avoiding vibration caused by the swing of the motor 120 during the driving process and causing abnormal noise. Moreover, since the hanger rod 200 is driven to swing back and forth by the crank arm 150, there is also a certain lever arm between the pin 140 and the rotation point of the crank arm 150. Under the same power, it can have a larger driving torque, that is, heavier clothes can be hung on the hanger rod 200, and the carrying capacity of the flip hanger is also improved.

[0050] See also Figure 1 This is an embodiment of the electric flip clothes hanger of the utility model, which includes two flip power members 100 and a hanger rod 200. The two flip power members 100 are respectively fixed on two opposite side walls of the cabinet, and the two ends of the hanger rod 200 are respectively connected to the corresponding flip power members 100. The hanger rod 200 is driven by the flip power member 100 to switch between the storage position and the taking position. Generally, when in the storage position, the entire electric flip clothes hanger is in a vertical state, and the clothes are hung on the hanger rod 200. When the user needs to take the clothes, the hanger rod 200 is switched from the storage position to the taking position, and the hanger rod 200 is rotated 90 degrees in the direction of the cabinet door to a horizontal position, which is convenient for the user to take the clothes.

[0051] like Figures 2 to 8As shown, the flip power member 100 includes: a housing 110, a motor 120, a linear telescopic component 130 and a crank arm 150. The housing 110 is arranged horizontally, that is, the length direction of the housing 110 is parallel or approximately parallel to the depth direction of the cabinet. Since clothes are to be hung on the hanger rod 200, sufficient space must be left between the hanger rod 200 and the rear side of the cabinet. The housing 110 is arranged horizontally to just utilize the distance between the hanger rod 200 and the rear side of the cabinet, reducing the space occupied by the housing 110 in the vertical direction, thereby reducing the vertical space demand of the electric flip hanger. The motor 120 is electrically connected to a control unit 121, and the control unit 121 is arranged on a circuit board. The motor 120 and the circuit board are fixed together in the housing 110, and the circuit board where the control unit 121 is located is parallel to the inner side wall of the cabinet, so that the thickness of the housing 110 can be reduced and the housing 110 can be made thinner. In order to allow the housing 110 to be in a horizontal position, the linear telescopic part is connected to a pin 140 that moves linearly along the length direction of the housing 110. It is best that the linear telescopic part is also arranged along the length direction of the housing 110 to make full use of the space in the length direction of the housing 110. Correspondingly, a slide groove 160 is opened on the crank arm 150. The linear telescopic part is driven by the motor 120 to drive the pin 140 to slide in the slide groove 160, thereby driving the crank arm 150 to rotate, driving the hanger rod 200 connected to the crank arm 150 to swing back and forth, and switch between the storage position and the taking position. Through the above structure, the space occupied by the flip power part 100 in the vertical direction is minimized, and it is arranged in the depth direction of the cabinet with a larger space, so that the entire electric flip hanger reduces the space requirement in the height direction of the cabinet. For electric flip hangers of the same height, the hanger rod 200 will also have a lower height when it is turned to the taking position, which is convenient for users to take clothes. A slot is opened on the housing 110 for the crank arm 150 to extend, and the crank arm 150 can slide in the slot when swinging. In order to prevent dust from entering the shell 110 through the slot, a blocking piece 111 is provided in the shell 110 to close the slot. The blocking piece 111 has an opening and is sleeved on the curved arm 150. The blocking piece 111 slides closely against the inner wall of the shell next to the slot, thereby ensuring that the blocking piece 111 can slide with the curved arm 150 and can prevent dust from entering the shell 110 through the slot.

[0052] Furthermore, the length direction of the slide groove 160 forms an acute angle or an obtuse angle with the movement direction of the pin shaft 140, so that when the pin shaft 140 slides in the slide groove 160, it will generate a component force on the side wall of the slide groove 160 to drive the crank arm 150 to rotate, thereby driving the crank arm 150 to rotate.

[0053] Furthermore, the curved arm 150 includes a swinging part 151 and a transmission part 152, the hanger rod 200 is connected to the swinging part 151, and the slide groove 160 is opened on the transmission part 152. The slide groove 160 is generally opened along the length direction of the transmission part 152, so that a longer length of the slide groove 160 can be obtained, and when the pin shaft 140 drives the curved arm 150 to rotate, it has a sufficient swing amplitude, and the angle between the swinging part 151 and the transmission part 152 is an acute angle or an obtuse angle, ensuring that when the pin shaft 140 makes linear motion along the length direction of the shell 110, it can drive the curved arm 150 to drive the hanger rod 200 to slide smoothly between the existing position and the taking position without any dead point.

[0054] The swing part 151 of the crank arm 150 can be a whole long rod, or can be made up of two or more sections, so as to reduce the space occupied during transportation. In this embodiment, the swing part 151 is composed of two sections, one section is integrally arranged with the transmission part 152, and the other section is in the shape of a rod, and the two sections are connected together by sleeve connection and bolt connection, so that the two sections are connected as a whole.

[0055] like Figure 7 , Figure 8 As shown, in this embodiment, the linear telescopic component 130 is a screw assembly, which includes a screw body 131 and a transmission member 132 threadedly connected to the screw body 131. The screw body 131 is arranged along the length direction of the shell 110 to fully utilize the space in the length direction of the shell 110. The transmission member 132 can be a nut or a sleeve with an internal thread. In order to obtain a better driving effect, the transmission member 132 in this embodiment adopts a threaded sleeve, and a notch 133 is opened at the front end of the sleeve. The pin 140 is fixed in the notch 133. The notch 133 is used to avoid the crank arm 150, and can also support both ends of the pin 140, thereby ensuring that the pin 140 will not deviate when subjected to force. In order to ensure that the transmission member 132 can move along the length direction of the screw rod when the screw rod rotates, thereby driving the pin shaft 140 to perform linear motion, in this embodiment, the transmission member 132 and the housing 110 cooperate to limit the sliding direction of the transmission member 132 through the guide groove and the guide block. The housing 110 is provided with a guide block, and the outer surface of the transmission member 132 is provided with a guide groove along the length direction of the transmission member 132 to achieve the above purpose. In addition, a limit switch 112 is also provided in the housing 110, and a trigger member 135 is provided on the transmission member 132. The trigger member moves with the transmission member 132. The limit switch 112 is provided with two movement positions of the transmission member 132 when the crank arm 150 swings to the storage position and the taking position. After the trigger member triggers the limit switch 112, the limit switch 112 sends an electrical signal to the control unit 121 to stop the operation of the motor 120.

[0056] In addition to the above-mentioned screw assembly, the linear telescopic component 130 can also use an electric cylinder, which is also arranged along the length direction of the shell 110. The pin 140 is fixed on the piston of the electric cylinder, which can also realize the linear movement of the pin 140 along the length direction of the shell 110.

[0057] The motor 120 driving the linear telescopic component 130 includes but is not limited to the following installation forms:

[0058] One is to install the motor 120 vertically and the horizontal height of the motor 120 is higher than the linear telescopic component 130, that is, the motor 120 is inverted, the shaft of the motor 120 extends downward, and the shaft of the motor 120 is connected to the screw body 131 of the linear telescopic component 130 through a worm gear transmission, so as to make full use of the space above the linear telescopic component 130 and avoid the motor 120 occupying the space below the linear telescopic component 130;

[0059] Another method is to coaxially arrange the motor 120 and the linear telescopic component 130. If the lateral space is sufficient, this arrangement allows the motor 120 to be directly connected to the linear telescopic component 130, reducing the intermediate connecting components, and controlling the running speed of the linear telescopic component by the rotation speed of the motor 120. In addition to directly driving the linear telescopic component 130 of the screw assembly, this arrangement of the motor 120 can also drive the electric cylinder.

[0060] like Figures 2 to 6 As shown, on the basis of the above embodiment, in order to ensure the safe operation of the electric flip hanger, a distance sensor 170 connected to the control unit 121 can also be set on the crank arm 150 to sense the safe operation of the hanger rod 200 when it swings between the storage position and the taking position. If it is detected that it is too close to other objects, the distance sensor 170 will send a signal to the control unit 121 to stop the motor 120 to prevent accidents. Generally speaking, the most likely accident is that the hanger rod 200 switches from the storage position to the taking position. At this time, if the user is too close to the running path of the hanger rod 200 or the wardrobe door is not opened and the remote control pneumatic electric flip hanger is operated by mistake, it may cause accidents and cause the user to be injured or the wardrobe door to be damaged. Therefore, it is best to install the distance sensor 170 at the end of the crank arm 150 connected to the hanger rod 200, and face the direction of the hanger rod 200 turning downward, that is, the direction of the hanger rod 200 running from the storage position to the taking position. The distance sensor 170 can detect whether there is an obstacle blocking the front during this operation.

[0061] The distance sensor 170 can be an infrared reflective sensor or an ultrasonic sensor, which detects the distance between the distance sensor and the cabinet door in real time. If the cabinet door is in a closed state, the transmitting end of the distance sensor 170 emits infrared light or ultrasonic waves, which are received by the receiving end of the distance sensor 170, and the distance between the distance sensor 170 and the cabinet door is calculated. If the distance is too close, the cabinet door is deemed to be in a closed state, and the motor 120 will not run; if the infrared light or ultrasonic wave emitted by the distance sensor 170 is not reflected back, it means that the cabinet door has been opened and the motor 120 can be started normally.

[0062] A flip switch 180 is provided at the end where the curved arm 150 of at least one flip power member 100 is connected to the hanger rod 200. The flip switch 180 is electrically connected to the control unit 121. Through the flip switch 180, after the user takes or puts the clothes, the electric flip hanger can be conveniently controlled to start and the hanger rod 200 can be returned to the storage position without having to look for the remote control for operation, which greatly facilitates the user's operation.

[0063] If the electric flip hanger is not equipped with a distance sensor 170 or an obstacle in the blind area of ​​the distance sensor 170 hits the electric flip hanger during the flipping process, the object or the electric flip hanger will be damaged. Therefore, in this embodiment, an obstacle sensor 190 can also be fixed on the crank arm 150. The obstacle sensor 190 can detect the deformation of the crank arm 150. Specifically, the obstacle sensor 190 is fixed on the swing part 151 of the crank arm 150. When the crank arm 150 encounters an obstacle, the swing part 151 is most likely to deform. When the hanger rod 200 hits an obstacle during the flipping process, the crank arm 150 will be deformed to a certain extent. After the obstacle sensor 190 detects that the deformation exceeds the preset value, it will send an electrical signal to the control unit 121 to stop the motor 120 from running, so as to avoid the motor 120 from burning or the crank arm 150 from being damaged.

[0064] Furthermore, the resistance sensor 190 can be a piezoelectric sheet or a strain gauge, and mounted on the curved arm 150. The piezoelectric sheet and the strain gauge have high detection sensitivity. When the curved arm 150 is obstructed and slightly deformed, it can detect and send an electrical signal to the control unit 121 in time. The bonding method can also facilitate installation and simplify the installation steps without affecting the detection accuracy of the resistance sensor 190. The resistance sensor 190 is electrically connected to the control unit 121 through a wire, which is guided from the inside of the curved arm 150, that is, the wire is in a hidden state to avoid being caught during use.

[0065] When the curved arm 150 is obstructed, the obstruction point will form a fulcrum, and the driving force applied by the motor 120 will act on one end of the swing part 151, causing the part of the swing part 151 between the rotation point and the obstruction point to deform. Therefore, the installation position of the resistance sensor 190 on the curved arm 150 is closer to the shell 110 than the hanger rod 200, so that it can be discovered as early as possible whether the curved arm 150 encounters resistance, avoiding irreversible damage to the curved arm 150.

[0066] The resistance sensor 190 is respectively installed on the curved arm 150 of the two flip power parts 100. The resistance sensor 190 is bonded to the curved arm 150 by double-sided adhesive. The resistance sensor 190 collects the bending signal change of the curved arm 150, and then sends the signal to the MCU of the control unit 121 for processing. The resistance sensor 190 can sense the slight deformation of the curved arm 150, and amplifies the slight deformation of the curved arm 150 into a changing voltage signal through the sensor and the processing circuit. When the curved arm 150 encounters an obstacle, the curved arm 150 will deform to a certain extent due to the force, and the deformation can be collected by the resistance sensor 190, converted into a voltage signal to be collected and recognized by the MCU. After the MCU determines that the operation is obstructed, it immediately controls the motor 120 to reverse, thereby achieving the purpose and effect of anti-pinch.

[0067] The electric flip clothes hanger of this embodiment also includes a mounting plate 300. Each shell 110 corresponds to a mounting plate 300. During installation, the mounting plate 300 is first fixed to the inner wall of the cabinet. A slot corresponding to the mounting plate 300 is opened on the shell 110. The shell 110 only needs to be aligned with the mounting plate 300 and snap-connected with it to complete the fixed installation of the shell 110.

[0068] Through the above structure, the electric flip hanger rearranges the component positions of the flip power part 100, so that the entire electric flip hanger requires less space in the vertical direction, and during operation, the motor 120 remains relatively still relative to the shell 110, and does not swing to generate additional noise, which is also more conducive to the smooth operation of the motor 120. The motor 120 drives the linear telescopic component 130 to drive the crank arm 150 to rotate. The setting of the crank arm 150 makes the power driving the crank arm 150 to rotate have a certain power arm, and the power demand is relatively smaller, which is conducive to reducing costs, or having a larger driving torque under the premise that the power of the original motor 120 remains unchanged, that is, heavier clothes can be hung on the hanger rod 200, and the carrying capacity of the flip hanger is also improved.

[0069] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
