Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0055] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0056] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0057] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0058] As disclosed in the background section, some existing pull-out storage devices have open and close buttons. When the user presses the open button, the motor drives the drawer to open. However, when it is necessary to close the drawer, the open drawer often obstructs the user's ability to press the close button. Embodiments of this application provide a pull-out storage device that at least addresses this technical problem.

[0059] Please refer to Figures 1-4 The pull-out storage device provided in the embodiments of this application includes a mounting body 1, a drawer 2, and a driving component 3. The driving component 3 is disposed on the mounting body 1 and connected to the drawer 2. The driving component 3 is used to drive the drawer 2 to move relative to the mounting body 1. A triggering device 11 is disposed on the mounting body 1 and electrically connected to the driving component 3. A switch engaging part 21 is disposed on the drawer 2. When the drawer 2 is open, the triggering device 11 is triggered when the switch engaging part 21 moves away from the triggering device 11, thereby causing the driving component 3 to drive the drawer 2 to close.

[0060] Mounting body 1 serves as the mounting base for drawer 2, and drive component 3 is fixed to mounting body 1; switch mating part 21 can be a protrusion set on drawer 2, trigger device 11 is electrically connected to drive component 3, when trigger device 11 is triggered, drive component 3 can receive a signal, and drive component 3 will drive drawer 2 to move after receiving the signal.

[0061] It should be noted that the triggering of the triggering device 11 includes two triggering modes: the triggering device 11 being turned on and off, and there is no limitation on this.

[0062] In this embodiment, the drawer 2 is open when it is fully open. When the drawer 2 is fully open, the triggering device 11 will be triggered when the switch engagement part 21 moves a certain distance away from the triggering device 11. The distance that the switch engagement part 21 moves away from the triggering device 11 is the distance that the user pushes the drawer 2.

[0063] When drawer 2 is open, the user does not need to press the close button, but only needs to push drawer 2 to move it, so that the switch engagement part 21 moves a certain distance away from the trigger device 11. At this time, the trigger device 11 will be triggered, the drive unit 3 will receive a signal, and the drive unit 3 will drive drawer 2 to move so that drawer 2 is closed. Compared with the original drawer 2 closing method of pressing the close button, the operation is more convenient.

[0064] In this embodiment, the pull-out storage device also includes a controller, which is electrically connected to both the triggering device 11 and the driving component 3. When the triggering device 11 is triggered, it sends a signal to the controller, and the controller controls the driving component 3 to run after receiving the signal.

[0065] In some embodiments, the triggering device 11 is a contact triggering device, for example, the triggering device 11 may be a contact switch. When the drawer 2 is open, the switch engaging part 21 abuts against the triggering device 11, and the triggering device 11 is used to be triggered when the switch engaging part 21 disengages from the triggering device 11.

[0066] When the triggering device 11 is a contact triggering device, the user pushes the drawer 2 to move, causing the switch engagement part 21 to move a certain distance away from the triggering device 11 until the switch engagement part 21 disengages from the triggering device 11. At this time, the triggering device 11 will be triggered and send a signal to the controller. After receiving the signal, the controller controls the drive unit 3 to drive the drawer 2 to move so that the drawer 2 is closed.

[0067] In addition, the triggering device 11 is also used to be triggered when the switch engagement part 21 moves toward the triggering device 11 and the switch engagement part 21 abuts against the triggering device 11, thereby controlling the drive member 3 to stop running through the controller so that the drawer 2 remains open.

[0068] When opening drawer 2, the drawer 2 can be moved by pressing the existing open button or by voice control via the controller to drive the drive unit 3. During the movement of drawer 2, the switch engagement part 21 moves toward the trigger device 11 until the switch engagement part 21 abuts against the trigger device 11. At this time, the trigger device 11 is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive unit 3 to stop running, and the drawer 2 reaches the maximum open position.

[0069] In some other embodiments, the triggering device 11 is an inductive switch, and the switch mating part 21 does not need to contact the triggering device 11.

[0070] During the opening of drawer 2, the switch engagement part 21 gradually approaches the trigger device 11. The trigger device 11 senses the switch engagement part 21 and is triggered. At this time, the trigger device 11 sends a signal to the controller. After receiving the signal, the controller controls the drive component 3 to stop running, and drawer 2 reaches the maximum open position. When it is necessary to close drawer 2, the user pushes drawer 2 to move, causing the switch engagement part 21 to move a certain distance away from the trigger device 11. At this time, the switch engagement part 21 is removed from the sensing area of ​​the trigger device 11, the trigger device 11 is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive component 3 to drive drawer 2 to close.

[0071] In this embodiment, a first sliding member is provided on the drawer 2, and the first sliding member is fixedly connected to the drawer 2. A second sliding member is slidably provided on the first sliding member, and the first sliding member is connected to the drawer 2. The second sliding member is connected to the driving member 3. When the drawer 2 is open, the triggering device 11 is triggered when the first sliding member slides relative to the second sliding member, thereby causing the driving member 3 to drive the second sliding member to move. During the movement, the second sliding member drives the first sliding member and the drawer 2 to move synchronously.

[0072] By setting a first slider and a second slider that can slide relative to each other, when the drawer 2 is open, if the user pushes the drawer 2, the first slider slides relative to the second slider. At the same time, the switch engagement part 21 disengages from the trigger device 11, and the trigger device 11 is triggered, which in turn causes the drive member 3 to drive the second slider to move. The second slider drives the first slider and the drawer 2 to move synchronously until the drawer 2 is closed.

[0073] In some embodiments, the first slider is a housing 22, and the second slider is a slider 23, which is slidably disposed within the housing 22.

[0074] The drawer 2 is provided with a groove 24 for accommodating the housing 22. The housing 22 is embedded in the groove 24, and the housing 22 is provided with a first mounting hole 221 for fasteners such as screws to pass through. After the screw passes through the first mounting hole 221, it connects with the bottom wall of the groove 24 to fix the housing 22 in the groove 24.

[0075] It should be noted that when the user pushes the drawer 2 to move, the switch engagement part 21 and the housing 22 move synchronously with the drawer 2. While the switch engagement part 21 moves a certain distance away from the trigger device 11, the housing 22 slides relative to the slider 23. At this time, the trigger device 11 will be triggered and send a signal to the controller. After receiving the signal, the controller controls the drive component 3 to drive the slider 23 to move. During the movement, the slider 23 drives the housing 22 and the drawer 2 to move synchronously until the drawer 2 is closed.

[0076] Furthermore, a first elastic element 25 is provided inside the housing 22. The first elastic element 25 acts on the slider 23 to fix the slider 23 relative to the housing 22. When the first elastic element 25 acts on the slider 23 to fix the slider 23 relative to the housing 22, the drive member 3 drives the slider 23 to move, which will cause the housing 22 and the drawer 2 to move synchronously.

[0077] Since the drawer 2 has a certain resistance when sliding on the mounting body 1, the force exerted by the first elastic element 25 on the slider 23 must be greater than the resistance of the drawer 2 moving relative to the mounting body 1. Only when the driving element 3 drives the slider 23 to move can the housing 22 and the drawer 2 move synchronously.

[0078] Please refer to Figures 5-8 In some embodiments, the housing 22 is provided with a mounting groove 222, and the first elastic element 25 includes a torsion spring 251 and a spindle 252. The spindle 252 is disposed in the mounting groove 222, and the torsion spring 251 is sleeved on the spindle 252. The torsion spring 251 acts on the slider 23 so that the slider 23 is relatively fixed to the housing 22.

[0079] The spindle 252 passes through the torsion spring 251 and fixes the torsion spring 251 in the mounting groove 222. The torsion spring 251 acts on the slider 23 so that the slider 23 is relatively fixed to the housing 22. The force exerted by the torsion spring 251 on the slider 23 is greater than the resistance to the movement of the drawer 2 relative to the mounting body 1.

[0080] In addition, a sliding groove 223 is provided inside the housing 22, and the slider 23 slides in conjunction with the sliding groove 223.

[0081] The sliding groove 223 and the mounting groove 222 inside the housing 22 are separated. For example, the housing 22 is provided with a partition, which divides the inner cavity of the housing 22 into the sliding groove 223 and the mounting groove 222. Separating the sliding groove 223 and the mounting groove 222 allows the normal sliding process of the slider 23 to be unaffected by the torsion spring 251.

[0082] The slider 23 is roughly rectangular. The two opposite surfaces of the slider 23 are respectively attached to the two opposite inner walls of the slide groove 223, making the slider 23 slide more smoothly in the slide groove 223.

[0083] Furthermore, the slider 23 is provided with a flange 231, the housing 22 is provided with a stop surface 224, and one end of the torsion spring 251 is used to abut against the flange 231 and hold the flange 231 against the stop surface 224.

[0084] The flange 231 protrudes from the surface of the slider 23, and the stop surface 224 is disposed on the inner wall of the housing 22. When the resistance force of the torsion spring 251 on the slider 23 is greater than the resistance of the drawer 2 to the movement of the mounting body 1, it can ensure that one end of the torsion spring 251 abuts against the flange 231 and the flange 231 abuts against the stop surface 224, so that the driving member 3 can drive the slider 23 to move back and forth and drive the housing 22 and the drawer 2 to move synchronously. When the drawer 2 is in the open state, when the user pushes the drawer 2 to move, as long as the external pushing force is greater than the resistance force of the torsion spring 251 on the slider 23, the drawer 2 can drive the housing 22 to slide relative to the slider 23. Since the slider 23 is fixed, the flange 231 will disengage from the stop surface 224, thereby causing a certain displacement of the end of the torsion spring 251 that abuts against the flange 231.

[0085] In some embodiments, a limiting groove 225 is provided in the housing 22, and one end of the torsion spring 251 extends into the limiting groove 225. The limiting groove 225 is used to constrain the torsion spring 251 so that the end of the torsion spring 251 extending into the limiting groove 225 can swing along the motion plane of the slider 23.

[0086] The limiting groove 225 is provided on the inner wall of the housing 22. While one end of the torsion spring 251 abuts against the flange 231, the other end of the torsion spring 251 also extends into the limiting groove 225. The limiting groove 225 serves to constrain the movement direction of the torsion spring 251.

[0087] When the user pushes the drawer 2 to move, the drawer 2 causes the housing 22 to slide relative to the slider 23, and the flange 231 will disengage from the stop surface 224. Since the end of the torsion spring 251 that abuts against the flange 231 extends into the limiting groove 225, the end of the torsion spring 251 that abuts against the flange 231 will swing along the movement plane of the slider 23. In some other embodiments, the first elastic element 25 can also be a spring sheet or a spring. The spring sheet or spring is disposed between the housing 22 and the slider 23. When the user pushes the drawer 2 to move, the housing 22 slides relative to the slider 23, and the spring sheet or spring deforms. During the process of the driving member 3 driving the drawer 2 to open, the spring sheet or spring always abuts against the slider 23, so that the housing 22 can move synchronously with the slider 23.

[0088] In some embodiments, the slider 23 is provided with at least one mounting hole, and the pull-out storage device further includes a cable mechanism 4, the drive member 3 is connected to the cable mechanism 4 in a transmission manner, and the cable mechanism 4 cooperates with the mounting hole.

[0089] By setting up a cable mechanism 4 and connecting the drive component 3 to the cable mechanism 4, and the cable mechanism 4 cooperating with the mounting hole, the drive component 3 can drive the slider 23 to move through the cable mechanism 4 during operation. When one end of the torsion spring 251 abuts against the flange 231 and the flange 231 abuts against the stop surface 224, the housing 22 and the drawer 2 move synchronously with the slider 23.

[0090] Furthermore, the cable mechanism 4 includes a winding disc 41, a reversing disc 42, and a cable assembly 43. The winding disc 41 and the reversing disc 42 are rotatably mounted on the mounting body 1. The driving component 3 is connected to the winding disc 41 to drive the winding disc 41 to rotate. The cable assembly 43 is wound around both the winding disc 41 and the reversing disc 42, and the cable assembly 43 mates with the mounting hole.

[0091] The winding spool 41 and the reversing plate 42 are arranged along the moving direction of drawer 2. Please refer to... Figure 9 A slide rail seat 14 is fixedly installed on the mounting body 1, and a triggering device 11 is installed on the slide rail seat 14. The slide rail seat 14 and the drawer 2 are slidably engaged through a slide rail 26. The slide rail 26 generally includes two plates and a roller disposed between the two plates. One plate is fixedly connected to the slide rail seat 14, and the other plate is fixedly connected to the drawer 2. The two plates are slidably engaged through the roller in the middle.

[0092] A steering wheel bracket 12 is provided on the slide rail seat 14, and a rotating shaft 121 is provided on the steering wheel bracket 12. The steering wheel 42 rotates with the rotating shaft 121. A nut 1211 is provided at the end of the rotating shaft 121 away from the steering wheel bracket 12 to prevent the steering wheel 42 from disengaging.

[0093] During the operation of the drive unit 3, the drive unit 3 drives the winding disk 41 to rotate. Since the cable assembly 43 is wound around both the winding disk 41 and the reversing disk 42, and the cable assembly 43 is matched with the mounting hole, the cable assembly 43 can drive the reversing disk 42 to rotate synchronously with the winding disk 41, and drive the slider 23 to move.

[0094] Please refer to Figures 10-12 In some embodiments, the assembly hole includes a connected wire groove 232 and a second mounting hole 233, and an abutment surface 234 is provided at the connection between the second mounting hole 233 and the wire groove 232; the cable assembly 43 includes a cable 431, an end 432 and a second elastic member 433, the cable 431 passes through both the wire groove 232 and the second mounting hole 233, the end 432 is connected to one end of the cable 431, the end 432 is located in the second mounting hole 233, and the second elastic member 433 is disposed between the end 432 and the abutment surface 234 to tighten the cable 431.

[0095] The width of the groove 232 is smaller than the diameter of the second mounting hole 233. The diameter of the end face of the end 432 and the diameter of the abutment surface 234 are both slightly smaller than the diameter of the second mounting hole 233. The second elastic element 433 is disposed between the end 432 and the abutment surface 234 to tighten the cable 431.

[0096] There are two assembly holes, and the arrangement directions of the wire groove 232 and the second mounting hole 233 in the two assembly holes are opposite. There are two cable assemblies 43, and the two cable assemblies 43 correspond to the two assembly holes respectively. The cable 431 in one cable assembly 43 is wound around the winding reel 41, and one end of the cable 431 is connected to the end 432 in one of the second mounting holes 233. A second elastic element 433 is provided between the end 432 and the corresponding abutment surface 234. The cable 431 in the other cable assembly 43 is wound around both the winding reel 41 and the reversing disc 42, and one end of the cable 431 is connected to the end 432 in the other second mounting hole 233. A second elastic element 433 is provided between the end 432 and the corresponding abutment surface 234.

[0097] By providing two cable assemblies 43, each corresponding to a mounting hole, and a second elastic element 433 between the end 432 and the corresponding abutment surface 234 of each cable assembly 43, the cables 431 in both cable assemblies 43 can be kept taut, thereby allowing the slider 23 to move smoothly under the drive of the drive member 3. In some embodiments, the second elastic element 433 is a spring, with its two ends abutting against the end 432 and the abutment surface 234, respectively.

[0098] When the second elastic element 433 is a spring, and the two ends of the spring abut against the end 432 and the abutment surface 234 respectively, the spring can keep the cable 431 connected to the end 432 in a taut state.

[0099] In some embodiments, the drive component 3 is a window cranking motor, and a motor bracket 13 is provided on the mounting body 1, on which the window cranking motor is fixed. The window cranking motor is a conventional motor that works with the winding disc 41. The window cranking motor and the winding disc 41 are keyed together. When the window cranking motor is started, the winding disc 41 can rotate with the window cranking motor, thereby driving the reversing disc 42 and the cable 431 to move.

[0100] In some other embodiments, the driving component 3 may also include a motor and a worm gear mechanism that is driven to the motor. The motor is driven to the winding disc 41 through the worm gear mechanism. When the motor starts, the worm gear mechanism can also drive the winding disc 41 to rotate. Alternatively, the driving component 3 may also include a motor and a gear set that is driven to the motor. The motor is driven to the winding disc 41 through the gear set. When the motor starts, the gear set can also drive the winding disc 41 to rotate.

[0101] It is understandable that the drive component 3 can be determined according to actual needs, as long as it can drive the winding disc 41 to rotate. In some other embodiments, the cable mechanism 4 can also be replaced by a transmission system including belts and synchronous pulleys.

[0102] like Figure 12 As shown, when the two ends 432 are not collinear, the tension force F of the two cable assemblies 43 on the slider 23 generates a torsional torque T; when the two ends 432 are collinear, or when using belt drive, no torsional torque is generated on the slider 23. At this time, the constraint force requirement on the slider 23 is reduced, and the housing 22 can be integrated with the drawer 2 into a single part.

[0103] Figures 13-15 The three working states of the pull-out storage device are shown. Figure 12 The diagram shows that drawer 2 is in the closed state, the switch engagement part 21 is far from the trigger device 11, and one end of the torsion spring 251 holds the flange 231 against the stop surface 224. When the controller receives the signal to open drawer 2, the drive member 3 drives drawer 2 to open through the cable mechanism 4. Figure 13 The diagram shows the state of drawer 2 at its maximum open position. One end of torsion spring 251 holds flange 231 against stop surface 224, switch engagement part 21 holds against trigger device 11, and trigger signal causes drive 3 to stop running. Figure 14The diagram shows the state where drawer 2 is pushed inward a certain distance, resulting in relative displacement between housing 22 and slider 23. One end of torsion spring 251 swings a certain amplitude under the resistance of flange 231. Switch engagement part 21 just disengages from trigger device 11, triggering a signal to make drive member 3 run, thereby driving drawer 2 to close.

[0104] In some embodiments, please refer to Figure 16 The pull-out storage device includes a cable mechanism 4, a drive member 3 is connected to the cable mechanism 4, a fixing member 27 is provided on the drawer 2, the cable mechanism 4 and the fixing member 27 are connected by an elastic member, and the fixing member 27 is allowed to move relative to the cable mechanism 4 when the elastic member is compressed or stretched.

[0105] It should be noted that drawer 2 is also provided with a housing 28 for accommodating the fixing member 27. The housing 28 is part of drawer 2, and the fixing member 27 is a separate part independent of the housing 28. The fixing member 27 is fixedly connected to the housing 28, or the fixing member 27 is integrally formed with the housing 28. The fixing member 27 can be a fixing block. The elastic element is the spring in the cable mechanism 4. The connection method between the fixing member 27 and the cable mechanism 4 is the same as the connection method between the slider 23 and the cable mechanism 4, which will not be described in detail here.

[0106] When drawer 2 is open, triggering device 11 is triggered when fixing member 27 moves relative to cable mechanism 4, thereby causing drive member 3 to drive fixing member 27 to move, and causing drawer 2 to move synchronously.

[0107] When the user pushes the drawer 2 to move, the drawer 2 moves the fixing part 27, one of the springs in the pull cable mechanism 4 is compressed and the other spring is stretched until the switch engagement part 21 moves a certain distance away from the trigger device 11. At this time, the trigger device 11 will be triggered, the drive part 3 receives the signal and drives the drawer 2 to move so that the drawer 2 is closed.

[0108] Furthermore, the triggering device 11 is a contact triggering device, such as... Figure 16 As shown, the triggering device 11 is a contact switch, which is activated when the switch mating part 21 contacts or disengages from the triggering device 11; alternatively, the triggering device 11 can be a non-contact triggering device, such as... Figure 17 As shown, the triggering device 11 is a photoelectric switch, and correspondingly, the switch mating part 21 is a grating. When the drawer 2 is opened to the maximum, the grating is coupled with the photoelectric switch, the photoelectric switch sends a signal, and the driving component 3 stops running. When the user pushes the drawer 2 to move, the grating moves a certain distance away from or close to the photoelectric switch. At this time, the photoelectric switch will trigger a signal again to start the driving component 3 and thus drive the drawer 2 to close.

[0109] Please refer to Figure 18The embodiments of this application also provide a vehicle refrigerator, including a refrigeration module 5 and the above-mentioned pull-out storage device, wherein the mounting body 1 is a refrigerator body, and the refrigeration module 5 is disposed on the refrigerator body.

[0110] It should be noted that the refrigeration module 5 is a common module in existing refrigerators. The refrigeration module 5 is fixed on the refrigerator body, and the motor bracket 13 is fixed on the refrigeration module 5.

[0111] Figure 19 This is a schematic diagram of a pull-out storage device 6 or a car refrigerator 7 applied to a car. For example, the pull-out storage device 6 is installed on the front side of the passenger seat, or the car refrigerator 7 is installed on the back side of the armrest box, or the pull-out storage device 6 is installed in the trunk of the car as a storage box.

[0112] The working principle of the pull-out storage device 6 and the car refrigerator 7 provided in this application embodiment includes at least the following: During the process of opening the drawer 2, the drawer 2 is moved by pressing the open button or by voice control via the controller, which controls the drive component 3. During the movement of the drawer 2, the switch engagement part 21 moves towards the trigger device 11 until it abuts against the trigger device 11. At this point, the trigger device 11 is triggered and sends a signal to the controller. Upon receiving the signal, the controller stops the drive component 3, and the drawer 2 reaches its maximum open position. When it is necessary to close the drawer 2, the user pushes the drawer 2, causing the switch engagement part 21 to move a certain distance away from the trigger device 11 until it disengages from the trigger device 11. At this point, the trigger device 11 is triggered and sends a signal to the controller. Upon receiving the signal, the controller controls the drive component 3 to move the drawer 2, thereby closing the drawer 2.

[0113] The beneficial effects of the pull-out storage device 6 and the car refrigerator 7 provided in this application embodiment include at least the following: when the drawer 2 is open, the user does not need to press a button, but only needs to push the drawer 2 to move it, so that the switch engagement part 21 moves away from the trigger device 11 by a certain distance. At this time, the trigger device 11 will be triggered, and after the controller receives the signal, it controls the drive component 3 to drive the drawer 2 to move so that the drawer 2 closes. Compared with the original drawer 2 closing method of pressing a button, the operation is more convenient; by limiting the force of the torsion spring 251 on the slider 23 to be greater than the resistance of the drawer 2 relative to the mounting body 1, when the drive component 3 drives the slider 23 to move, the housing 22 and the drawer 2 can move synchronously and smoothly with the slider 23. The movement of the slider 23 is achieved through the setting of torsion spring 251 and slider 23, which makes the operating force and stroke of pushing the drawer 2 to close more precise, thus obtaining a more comfortable feel. The inner wall of the housing 22 is provided with a limiting groove 225, which can constrain the movement direction of torsion spring 251, so that the end of torsion spring 251 extending into the limiting groove 225 swings along the movement plane of slider 23, and torsion spring 251 can form effective contact with flange 231 of slider 23. By setting two cable assemblies 43, the cable 431 in the two cable assemblies 43 can be in a taut state under the action of the second elastic element 433, so that slider 23 can move smoothly under the drive of drive element 3.

[0114] In summary, the embodiments of this application provide a pull-out storage device 6 and a car refrigerator 7. When the drawer 2 is open, the user does not need to press the close button. He only needs to push the drawer 2 so that the switch engagement part 21 moves away from the trigger device 11 by a certain distance. The trigger device 11 will then be triggered, and the controller will control the drive component 3 to drive the drawer 2 to close. The closing operation of the drawer 2 is more convenient.

[0115] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
