Description

Technical Field

[0001] The present invention specifically relates to a pull-out device and a vehicle having the same. Background Technology

[0002] When pull-out devices (such as pull-out boxes) are installed inside the vehicle's passenger compartment, such as Figures 1 to 3 As shown, with the length direction of the pull-out device as the front-to-back direction of the actual vehicle and the pulling direction of the pull-out device as from back to front, this type of pull-out device generally includes a base assembly 1, a strip-shaped locking tongue A, a pull-out component 2, an outer protective plate 3, a handle assembly 4, a fixed housing 5, and a receiving housing J. The pull-out component 2 is a rectangular box-shaped container with an opening at the top. The base assembly 1 is located below the pull-out component 2. A slide rail structure (not shown) is provided between the base assembly 1 and the pull-out component 2 for the pull-out component 2 to complete the pulling action. The outer protective plate 3 is located on the outer side of the left and right surfaces of the pull-out component 2. The housing J is integrated with the front of the pull-out component 2, closing the front opening of the pull-out component 2 and having a structure that extends above the pull-out component 2. A pair of strip-shaped locking tongues A pass through the housing J and extend out of the housing J through the through hole D when locked. The handle assembly 4 controls the strip-shaped locking tongues A and is located on the front side of the housing J. A door-shaped fixed housing 5 covers the outside of the housing J and is fixedly connected to other parts of the vehicle. The inner side of the fixed housing 5 is provided with a lock box B, which has a lock hole C that can cooperate with the strip-shaped locking tongues A. Thus, when the pull-out device is locked, the strip-shaped locking tongues A pass through the through hole D and extend into the lock box B to engage with the fixed housing 5. When it is necessary to pull out the pull-out component 2, the strip-shaped locking tongues A will retract into the pull-out device along the left-right direction of the vehicle under the action of the handle assembly 4 and release the engagement with the fixed housing 5, so that the pull-out component 2 can be pulled out together with the handle assembly 4.

[0003] Please refer to further information. Figures 4 to 5 The housing J also includes a housing part K, a first transmission part E, a torsion spring I, and two second transmission parts F. The housing part K has a concave area in the middle, and the first transmission part E, the second transmission part F, and the torsion spring I are disposed in the concave area. The two second transmission parts F are located on the left and right sides of the first transmission part E and are rotatably disposed on the housing part K. A pair of strip-shaped locking tongues A are disposed on the rear side of the second transmission part F and connected to the second transmission part F. The torsion spring I is disposed on the lower side of the first transmission part E.

[0004] Specifically, the two ends of the torsion spring I abut against the lower part of the first transmission part E and the lower part of the concave area, respectively; the left and right sides of the lower part of the first transmission part E are provided with teeth, and the upper part of the first transmission part E is cuboid; correspondingly, the second transmission part F is an irregularly shaped part and its surface facing the first transmission part E is also provided with teeth, and the second transmission part F engages with the lower part of the first transmission part E by means of these teeth; at the same time, a sliding post G extending along the front-rear direction of the actual vehicle is provided on the end of the second transmission part F away from the first transmission part E, and a mating groove H is provided on the strip-shaped locking tongue A at the position corresponding to the sliding post G, in which the sliding post G can slide, and the mating groove H is provided along the vertical direction of the actual vehicle.

[0005] As described above, corresponding to these settings, the handle assembly 4 includes a handle body 41 that can rotate up and down and a follower part 42 connected to the rear of the handle body 41. The follower part 42 is located above the first transmission part E and can apply a downward force to the first transmission part E when the handle assembly 4 rotates. Thus, when the handle body 41 rotates upward under the action of external force, the follower part 42 will move downward and apply a downward force to the first transmission part E, causing the first transmission part E to move downward and the torsion spring I to deform elastically. At the same time, the second transmission parts F located on the left and right sides of the first transmission part E will be driven to rotate. At this time, the second transmission part F located on one side of the first transmission part E will rotate counterclockwise, and the second transmission part F located on the other side of the first transmission part E will rotate clockwise. The two second transmission parts F will drive the strip-shaped locking tongue A connected to them to move towards the center of the receiving part K, so that the strip-shaped locking tongue A is released from the engagement with the fixed housing 5, completing the unlocking of the pull-out device, so that the pull-out part 2 can be pulled out. Similarly, when the external force is removed, the first transmission part E will move upward under the elastic restoring force of the torsion spring I, and the strip-shaped locking tongue A will reset and engage with the fixed housing 5 again, so that the pull-out device returns to the locked state. It should be noted that, in order to ensure that the strip-shaped locking tongue A moves in the left-right direction of the actual vehicle during movement, the relevant technology will limit the strip-shaped locking tongue A in the up-down direction. This limiting effect can be achieved by constructing the shape of the receiving part K or adding additional limiting parts, which will not be elaborated here.

[0006] The disadvantage of the above-mentioned pull-out device design is that there is limited room for optimization of the jerkiness when locking. Specifically, in order to reduce the jerkiness when the strip-shaped locking tongue A is engaged and improve the smoothness of operation, a bevel is usually provided at the end of the strip-shaped locking tongue A that is used to engage with the fixed housing 5. However, since the length of the strip-shaped locking tongue A is limited, the slope of the bevel that can be provided on it is also very limited. Therefore, the effect of adjusting the strip-shaped locking tongue A to adjust the smoothness of the pull-out device is limited. Summary of the Invention

[0007] The purpose of this invention is to provide a pull-out device and a vehicle having the same.

[0008] The pull-out device provided by the present invention includes a fixed housing, a receiving member, a pull-out member, a moving magnetic part, and a fixed magnetic part. The fixed magnetic part and the moving magnetic part are each provided with alternately arranged N poles and S poles. The receiving member is connected to the pull-out member and can move with the pull-out member relative to the fixed housing. The moving magnetic part is rotatably disposed on the receiving member. The fixed magnetic part is fixed on the fixed housing and located near the moving magnetic part. The moving magnetic part can rotate relative to the fixed magnetic part under the action of an external force to change the interaction force between it and the fixed magnetic part, so that there is an attractive force and / or a repulsive force between the moving magnetic part and the fixed magnetic part, thereby locking or unlocking the pull-out device.

[0009] Optionally, the device further includes a handle assembly, which is located on one side of the pull-out member and can rotate relative to the pull-out member. The handle assembly is connected to the moving magnetic part. When the handle assembly rotates in a first direction, the moving magnetic part rotates relative to the fixed magnetic part, and the moving magnetic part and the fixed magnetic part repel each other or the force between them is zero, thus unlocking the pull-out device and allowing the pull-out member to move away from the fixed housing. When the handle assembly rotates relative to the pull-out member in a second direction, the moving magnetic part rotates in the opposite direction relative to the fixed magnetic part, and the moving magnetic part and the fixed magnetic part attract each other, causing the pull-out member to move in the opposite direction and reset, thus locking the pull-out device.

[0010] Optionally, it further includes a first housing, a rotating member, a transmission bridge, and an elastic member. The first housing is disposed on one end of the pull-out member. The fixed housing covers the first housing and the pull-out member. The accommodating member is disposed inside the first housing. The rotating member, the transmission bridge, and the elastic member are disposed on the accommodating member. The rotating member is located on the side of the transmission bridge, meshes with the transmission bridge, and is fixedly connected to the moving magnetic part. The elastic member is located between the transmission bridge and the accommodating member. When the handle assembly rotates relative to the pull-out member in a first direction under the action of an external force, the transmission bridge compresses the elastic member and drives the rotating member and the moving magnetic part to rotate. After the external force is removed, the elastic member pushes the transmission bridge to reset and drives the rotating member and the moving magnetic part to rotate in the opposite direction.

[0011] Optionally, the receiving member is provided with a through hole, the moving magnetic part is located in the through hole and can rotate within the through hole, the moving magnetic part is provided with a locking block that protrudes axially from the through hole, the rotating member is provided with a mating groove that can cooperate with the locking block, the rotating member is engaged with the moving magnetic part through the cooperation of the locking block and the mating groove, and the rotating member is fixedly connected to the moving magnetic part.

[0012] Optionally, the handle assembly includes a handle body and a follower connected to the handle body. The transmission bridge includes a contact portion and a rack connected to each other. The elastic element is located between the contact portion and the receiving member. The rack is located on the side of the contact portion and meshes with the rotating member. The follower is located near the contact portion and can apply force to the contact portion when the handle body rotates in a first direction, so that the contact portion compresses the elastic element. The rotating member and the moving magnet portion rotate relative to the fixed magnet portion.

[0013] Optionally, it further includes a guide plate, which is located on one side of the receiving member and fixedly connected to the receiving member. The rotating member is located between the guide plate and the receiving member. The rotating member is connected to the guide plate on the side away from the moving magnet and can rotate relative to the guide plate. The guide plate is provided with a first guide groove. A part of the contact portion extends into the first guide groove and the contact portion can move along the first guide groove.

[0014] Optionally, the rotating member has a recessed area on its surface facing the guide plate, and the guide plate has an annular protrusion that can engage with the recessed area.

[0015] Optionally, the receiving member is provided with a second guide groove, the contact portion is located between the handle body and the receiving member, and a protrusion extending outward perpendicular to the contact portion is provided on the side surface away from the handle body. The protrusion extends into the second guide groove and can slide along the second guide groove.

[0016] Optionally, the assembly further includes a second housing located within the first housing, with the receiving member and the guide plate located between the first housing and the second housing; the handle assembly also includes a rotating shaft located between the follower and the handle body, the rotating shaft being rotatably disposed on the second housing, the follower extending out of the second housing and into the guide plate, and extending above the contact portion.

[0017] Optionally, it also includes an exterior panel assembly disposed on the side of the first housing away from the pull-out member, and the exterior panel assembly is fastened to the fixed housing, the exterior panel assembly closing the first housing and exposing the handle body thereout.

[0018] The present invention also provides a vehicle including a pull-out device as described in any of the preceding claims.

[0019] In summary, by setting up a moving magnetic part and a fixed magnetic part, the moving magnetic part can change the force between itself and the fixed magnetic part under the action of external force. The pull-out device provided by the present invention does not need to set up a strip-shaped locking tongue, has the function of self-closing when closed and springing when opened, and also has high operation smoothness.

[0020] Furthermore, by providing an outer trim panel assembly at the front of the pull-out device (specifically on the side of the first housing away from the pull-out component), the outer trim panel assembly can be fastened to the fixed housing to close the first housing and expose only the handle body. That is, the front of the pull-out device is always exposed only by the handle body. The present invention can also provide a pull-out device with a hidden lock structure. Due to the use of a hidden lock, the pull-out device does not have the disadvantage of the exposed strip lock tongue in the related technology, and can greatly improve the premium appearance of the pull-out device.

[0021] The above description is merely an overview of the technical solution of the present invention.

Detailed Implementation

[0039] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0040] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] like Figure 6 and Figure 7As shown, this embodiment provides a pull-out device installed inside the passenger compartment of a vehicle. Taking the length direction of the pull-out device as the front-to-back direction of the vehicle, and the pulling direction as from back to front, this embodiment provides a moving magnetic part 6 and a fixed magnetic part 7 on the upper part of the pull-out device. Both the moving magnetic part 6 and the fixed magnetic part 7 are flat cylindrical. Multiple N poles and S poles are alternately formed on these two parts using magnetic printing technology. The circumferential angle occupied by each N pole and each S pole on the moving magnetic part 6 or the fixed magnetic part 7 is 60°. When the pull-out device is in a locked (also called engaged) state... In the normal state, the N pole of the moving magnetic part 6 is aligned with the S pole of the fixed magnetic part 7, and the S pole of the moving magnetic part 6 is aligned with the N pole of the fixed magnetic part 7, and the moving magnetic part 6 and the fixed magnetic part 7 attract each other. When it is necessary to unlock the pull-out device, simply rotate the moving magnetic part 6 by utilizing the principle that the shear force between the magnetic poles is much smaller than the attraction force, so that the N pole of the moving magnetic part 6 and the S pole of the fixed magnetic part 7 are gradually misaligned, and the S pole of the moving magnetic part 6 and the N pole of the fixed magnetic part 7 are gradually misaligned, until the attraction force between the moving magnetic part 6 and the fixed magnetic part 7 is equal to the repulsive force or the repulsive force is equal, and the locking of the pull-out device can be easily released.

[0042] As described above, the pull-out device includes a base assembly 1, a pull-out component 2, an outer protective plate 3, a handle assembly 4, a fixed housing 5, and a first housing 8. The pull-out component 2 is a rectangular box-shaped container with an open top. The base assembly 1 is located below the pull-out component 2. A slide rail structure (not shown) is provided between the base assembly 1 and the pull-out component 2 for the pull-out component 2 to complete the pull-out action. The outer protective plate 3 is located on the outer side of the left and right surfaces of the pull-out component 2. The first housing 8 is located at the front of the pull-out component 2, is integrated with the pull-out component 2 and closes the front opening of the pull-out component 2, and also has a structure that is higher than the pull-out component 2. In this embodiment, the handle assembly 4 is located on the upper front side of the first housing 8, and the door-shaped fixed housing 5 covers the outside of the first housing 8. The fixed housing 5 and the base assembly 1 are fixedly connected to other parts of the vehicle.

[0043] Please refer to the following: Figure 8 and Figure 9 In this embodiment, the fixed magnet part 7 is embedded in the rear part of the fixed housing 5 through a through area 52. The rear side of the fixed magnet part 7 is also provided with a rear protective plate 51 to conceal it and ensure the aesthetics of the pull-out device. Figure 10 and Figure 11As shown, the interior of the first housing 8 is provided with a receiving member 9, a guide plate 10, and a second housing 11 from back to front. The second housing 11 is bolted to the first housing 8, and the guide plate 10 is bolted to the first housing 8 and is pressed onto the receiving member 9 along the front-rear direction of the vehicle to fix the receiving member 9 onto the first housing 8. The moving magnet 6 is rotatably disposed on the receiving member 9. A first guide groove 101 leading to the receiving member 9 is opened in the middle of the guide plate 10 along the vertical direction of the vehicle. A transmission bridge 12 is slidably disposed in the first guide groove 101. A series of transmission mechanisms (see below) covered by the guide plate 10 are also provided between the receiving member 9 and the guide plate 10. Rotation upward is rotation along the first direction, and rotation downward is rotation along the second direction. When the handle assembly 4 rotates upward, the handle assembly 4 can drive the transmission bridge 12 to move downward, thereby driving these transmission mechanisms to move and drive the moving magnet 6 to rotate.

[0044] Specifically, please combine Figures 10 to 12 The transmission bridge 12 is irregularly shaped and includes a contact portion 121 and a rack 122. The contact portion 121 has a partial structure that fits with the first guide groove 101 with a clearance. The rack 122 is located between the guide plate 10 and the housing 9 and is arranged along the vertical direction of the actual vehicle. Two racks 122 are located on the left and right sides of the upper part of the contact portion 121, and each has a partial structure that is higher than the contact portion 121. The rack 122 is integrated with the contact portion 121, and its teeth face outward from the contact portion 121. The housing 9 is provided with a through hole 90 that can fit with the moving magnet 6 with a clearance. The moving magnet 6 is rotatably mounted on the housing 9 and has a portion that protrudes from the front surface of the housing 9. In this embodiment, the two moving magnets 6 are located on the left and right sides of the transmission bridge 12, and are spaced apart from the fixed magnet 7 through the rear sidewall of the first housing 8.

[0045] As described above, a rotating member 13 is also provided between the accommodating member 9 and the guide plate 10. This rotating member 13 is fixedly connected to the moving magnetic part 6 by means such as adhesive bonding, and it is provided with teeth that occupy about 1 / 3 of the circumferential length along the circumference. These teeth mesh with the rack 122. In this embodiment, an elastic member 14 (a spring in this embodiment) is fixedly connected to the lower surface of the contact part 121 by welding and stands upright between the accommodating member 9 and the contact part 121. The aforementioned handle assembly 4 includes a handle body 41, a follower part 42, and a rotating shaft 43. The handle body 41 and the follower part 42 are located on the front and rear sides of the rotating shaft 43 respectively and are connected as one unit. After the handle assembly 4 is assembled with the second housing 11, the rotating shaft 43 is rotatably mounted on the second housing 11, and the handle body 41 is located on the front side of the second housing 11. Figures 11 to 13As shown, the follower 42 passes through the second housing 11 and extends to the rear side of the second housing 11, while being located above the contact portion 121 and between the rack 122. Thus, when the handle body 41 rotates upward, the handle body 41 will drive the follower 42 to rotate downward and apply a downward force to the transmission bridge 12, causing the contact portion 121 to compress the elastic member 14. The contact portion 121 moves downward along the first guide groove 101 and drives the rack 122 to move downward as well, causing the rack 122 to drive the rotating member 13 that meshes with it to rotate, thereby rotating the moving magnet 6, ultimately achieving the purpose of changing the force between the moving magnet 6 and the fixed magnet 7.

[0046] Preferably, a locking block 15 consisting of a cylinder and a rectangular block is fixed in the middle of the moving magnet part 6, wherein the rectangular block is fixed to the moving magnet part 6, and the cylinder is fixed to the rectangular block and arranged along the front-rear direction of the actual vehicle, such as... Figure 14 As shown, the rotating member 13 is provided with two mating grooves: a first mating groove 131 and a second mating groove 132, which can respectively mate with the cylinder and the rectangular block. When the rotating member 13 is fastened onto the moving magnetic part 6, it also engages with the locking block 15, thereby increasing the contact area between the rotating member 13 and the moving magnetic part 6 and ensuring the reliability of the transmission between them. More preferably, the rotating member 13 can also be press-fitted with the locking block 15; in some possible embodiments, the rotating member 13 can also be tightly fastened to the portion of the moving magnetic part 6 that protrudes from the front surface of the receiving member 9, to further ensure the stability of the connection between the rotating member 13 and the moving magnetic part 6. Furthermore, the locking block 15 also facilitates the positioning operation during the assembly of the toothed rotating member 13 and the moving magnetic part 6.

[0047] Furthermore, the front surface of the rotating member 13 is provided with a forward-extending cylindrical protrusion and an annular protrusion, wherein the annular protrusion surrounds the outer periphery of the cylindrical protrusion and forms a recessed area 17 between itself and the cylindrical protrusion. Correspondingly, an annular protrusion (not shown) is also provided on the rear surface of the guide plate 10. The annular protrusion can engage with the recessed area 17 to ensure the stability of the rotating member 13 when it rotates in the pull-out device.

[0048] More preferably, in this embodiment, the contact portion 121 is further provided with a protrusion 1211 that protrudes vertically rearward from its rear surface. The middle of the receiving member 9 is provided with a second guide groove 91 that passes through it. The protrusion 1211 cooperates with the second guide groove 91 and can slide up and down in the second guide groove 91 to cooperate with the first guide groove 101 of the guide plate 10, so that the contact portion 121 has a reliable expected movement trajectory for sliding in the vertical direction of the actual vehicle. In some possible embodiments, when the pull-out device is in the locked state, the elastic member 14 is in a slightly compressed state, and the protrusion 1211 abuts against the upper edge of the second guide groove 91 to ensure the stability of the transmission bridge 12 in the pull-out device at this time.

[0049] Based on the above description, in this embodiment, the pull-out component 2, the first housing 8, the accommodating component 9, the second housing 11, and the handle assembly 4 are fixed together with the moving magnetic part 6 (or directly or indirectly). The fixed housing 5 is fixedly connected to the fixed magnetic part 7. When the pull-out device is in the locked state, the N pole of the moving magnetic part 6 is aligned with the S pole of the fixed magnetic part 7, and the S pole of the moving magnetic part 6 is aligned with the N pole of the fixed magnetic part 7. The force between the magnetic poles of the moving magnetic part 6 and the fixed magnetic part 7 is an attraction force. The components such as the first housing 8, the accommodating component 9, the second housing 11, and the handle assembly 4 are firmly attracted together with the fixed housing 5. When the occupant needs to unlock the pull-out device, the handle body 41 rotates and drives the moving magnetic part 6 to rotate. When the moving magnetic part 6 rotates 30°, half of the S pole of the moving magnetic part 6 is aligned with the N pole of the fixed magnetic part 7, and the other half of the S pole is aligned with the S pole of the fixed magnetic part 7. Alignment: Half of the N pole of the moving magnetic part 6 is aligned with the S pole of the fixed magnetic part 7, and the other half of the N pole is aligned with the N pole of the fixed magnetic part 7. The repulsive and attractive forces between the moving magnetic part 6 and the fixed magnetic part 7 cancel each other out. At this time, the occupant can pull out the pull-out piece 2 forward. Of course, the occupant can also continue to rotate the handle body 41 without pulling out the pull-out piece 2 when the moving magnetic part 6 is rotated 30°, until the S pole on the moving magnetic part 6 is aligned with the S pole of the fixed magnetic part 7, and the N pole on the moving magnetic part 6 is aligned with the N pole of the fixed magnetic part 7. At this time, the force between the moving magnetic part 6 and the fixed magnetic part 7 is a repulsive force. The occupant will clearly feel the rebound force. The occupant can easily pull out the pull-out piece 2 by applying a little force outward along this force. At the same time, the first housing 8, the housing 9, the second housing 11, and the handle assembly 4 all move forward relative to the fixed housing 5 and the base assembly 1. Similarly, when the passenger finishes placing or retrieving an item, the force applied to the handle body 41 is removed. Under the elastic restoring force of the elastic member 14, the transmission bridge 12 will reset, and the moving magnetic part 6 will also return to a state where its N pole is aligned with the N pole of the fixed magnetic part 7, and its S pole is aligned with the S pole of the fixed magnetic part 7. Then, by pushing back the pull-out member 2, the moving magnetic part 6 and the fixed magnetic part 7 will spontaneously attract each other when the distance between them is close enough. This will trigger a self-attraction effect on the pull-out device caused by the magnetic poles of the moving magnetic part 6 and the fixed magnetic part 7 attracting each other, allowing the pull-out device to smoothly return to the locked state.

[0050] In summary, by setting up a moving magnetic part 6 and a fixed magnetic part 7, the moving magnetic part 6 can change the force between itself and the fixed magnetic part 7 under the action of external force. The pull-out device provided by the present invention does not need to be set with a strip-shaped locking tongue, has the function of self-closing when closed and rebounding when opened, and also has high operation smoothness.

[0051] Furthermore, by providing a [missing information - likely a feature or design feature] at the front of the pull-out device (specifically on the side of the first housing 8 away from the pull-out member 2), Figure 6The exterior panel assembly 16 shown is designed to engage with the fixed housing 5 to close the first housing 8 and expose only the handle body 41 (i.e., the front of the pull-out device is always exposed with only the handle body 41 exposed). The present invention also provides a pull-out device with a hidden lock structure. Due to the use of a hidden lock, the pull-out device does not have the disadvantage of exposed strip lock tongue in related technologies, and can greatly improve the premium appearance of the pull-out device.

[0052] It should be noted that the pull-out device in this invention can not only be directly used as a pull-out device installed inside a vehicle, but can also be applied to other products that have pull-out and locking requirements, such as pull-out flip ashtrays, glove boxes, pull-out flip USB ports, etc. For example, those skilled in the art can directly use the pull-out device provided by this invention to realize the pull-out function of the ashtray, and then separately set the flip structure of the ashtray.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
