Description

Technical Field

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

[0002] like Figures 1 to 3 As shown, when the pull-out device is installed inside the passenger compartment of a vehicle, it is considered to be installed along the front-to-back direction of the actual vehicle and pulled out from front to back. In the following text, the end of the pull-out device located at the rear of the passenger compartment is referred to as the front end of the pull-out device, and the end located at the front of the passenger compartment is referred to as the rear end of the pull-out device. 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 first housing 6. 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 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 6 is integrated with the pull-out component 2 at the front part of the pull-out component 2, which closes the front opening of the pull-out component 2 and has a part structure that is higher than the pull-out component 2. A pair of strip-shaped locking tongues A are inserted into the first housing 6 and protrude from the first housing 6 through the through holes D on both sides of the first housing 6 when locked. The handle assembly 4 can control the strip-shaped locking tongues A and is located on the front side of the first housing 6. The door-shaped fixed housing 5 is covered on the outside of the first housing 6 and fixedly connected to other parts of the vehicle. The inner side of the fixed housing 5 is provided with a lock box B, and the lock box B is provided with a lock hole C that can cooperate with the strip-shaped locking tongues A. Thus, when the pull-out device is in the locked state, the strip-shaped locking tongue A passes through the through hole D and extends into the lock box B to engage with the fixed housing 5. When it is necessary to pull out the pull-out part 2, the strip-shaped locking tongue A will retract into the pull-out device along the left and right direction of the actual vehicle under the drive of the handle assembly 4 and release the engagement with the fixed housing 5, so that the pull-out part 2 can be pulled out together with the handle assembly 4.

[0003] Please refer to further information. Figures 4 to 5 The first housing 6 also includes a receiving member 7, a first transmission part E, a torsion spring I, and two second transmission parts F. The receiving member 7 has a recessed area in the middle, and the first transmission part E, the second transmission part F, and the torsion spring I are disposed in the recessed 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 receiving member 7. A pair of strip-shaped locking tongues A are respectively disposed on the side of the second transmission part F away from the first transmission part E and connected to the corresponding 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 bottom of the recessed area of ​​the accommodating member 7, 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 at the end of the second transmission part F away from the first transmission part E, and a mating groove H is provided on the end of the strip-shaped locking tongue A near the second transmission part F, in which the sliding post G can slide, and the mating groove H extends along the upper and lower sides of the actual vehicle.

[0005] As described above, corresponding to these settings, the handle assembly 4 includes a handle body 41 that can rotate upward or downward and a follower part 42 connected to the rear of the handle body 41; the follower part 42 is located on the upper side of the upper part of 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 member 7, so that the strip-shaped locking tongue A is released from the engagement with the fixed housing 5, thereby completing the unlocking of the pull-out device and allowing the pull-out member 2 to 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 upper and lower lateral directions. This limiting effect can be achieved by constructing the shape of the receiving part 7 or adding limiting accessories, which will not be elaborated here.

[0006] The drawback of the aforementioned pull-out device design is the limited room for improvement in terms of the smoothness of locking. Specifically, in related technologies, to improve the smoothness of locking the strip-shaped latch A, a bevel is usually provided at the end of the strip-shaped latch A that engages with the fixed housing 5. However, since the length of the strip-shaped latch A is limited, the slope of the bevel that can be provided on it is also very limited, resulting in limited effectiveness in adjusting the smoothness of pulling out this type of pull-out device by adjusting the shape of the strip-shaped latch A. 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 present invention provides a pull-out device comprising a pull-out component, a transmission arm, a locking component, and a reset elastic component. The transmission arm is disposed on the pull-out component and can move inward or outward together with the pull-out component, extending from a first side of the pull-out component to a second side opposite to the first side. The pull-out component is provided with a protrusion extending towards its second side. The locking component is located on the movement path of the pull-out component and can lock with the protrusion. The first end of the locking component can be detachably engaged with the transmission arm, and the second end of the locking component is located between the reset elastic component and the pull-out component. When the transmission arm is engaged with the locking component, the transmission arm can drive the locking component to rotate and compress the reset elastic component under the action of external force, releasing the locking component from the protrusion and allowing the pull-out component to move outward. When the pull-out component moves inward, the locking component can be pushed by the reset elastic component to lock with the protrusion again and lock the pull-out component.

[0009] Optionally, it also includes a base assembly located on the second side of the pull-out member, the pull-out member being movable relative to the base assembly, a locking member located between the pull-out member and the base assembly, the middle part of the locking member being rotatably disposed on the base assembly, and when the transmission arm applies force to the locking member under the action of an external force, the first end and the transmission arm can rotate toward the pull-out member, and the second end can rotate away from the pull-out member.

[0010] Optionally, it also includes an auxiliary assembly fixed to the base assembly, wherein a lock shaft is fixed on the lock, and a shaft support is provided on the auxiliary assembly. The shaft support is located on both sides of the lock, and the lock shaft is rotatably mounted on the shaft support.

[0011] Optionally, it also includes a receiving member, which is provided with a pressing plate and a toothed transmission member. The pressing plate can move relative to the receiving member under the action of an external force. The toothed transmission member is rotatably disposed on the receiving member, with one end meshing with the transmission arm and the other end slidably connected to the pressing plate. When the pressing plate moves under the action of an external force, it can drive the toothed transmission member to rotate and drive the transmission arm to move towards the pull-out member.

[0012] Optionally, the receiving member is provided with first limiting guide rails at both ends, and the two ends of the pressing plate cooperate with the first limiting guide rails and can slide along the first limiting guide rails.

[0013] Optionally, the toothed transmission component is located on both sides of the transmission arm, with teeth at the end near the transmission arm and lugs at the end away from the transmission arm. The pressing plate is provided with a follower post extending from the pressing plate into the lug. When the pressing plate moves towards the second side of the pull-out component under the action of external force, the toothed transmission components located on different sides of the transmission arm are driven by the follower post and rotate in opposite directions, causing the transmission arm to move towards the pull-out component.

[0014] Optionally, it further includes an elastic element and a first housing, the first housing being located at one end of the pull-out member, the receiving member being disposed inside the first housing, the elastic element being located between the first housing and the transmission arm and being fixedly connected to the transmission arm, the transmission arm moving towards the pull-out member under the drive of the toothed transmission member, the elastic element being compressed, and the transmission arm being reset under the push of the elastic element after the external force is removed.

[0015] Optionally, the transmission arm is L-shaped, extending from the upper side of the pull-out member, through the front side of the pull-out member, to the lower side of the pull-out member. The receiving member is provided with a transmission limiting guide rail, which protrudes outward from the receiving member. The upper part of the transmission arm cooperates with the transmission limiting guide rail and can slide along the transmission limiting guide rail. A U-shaped limiting member is provided near the lower part of the transmission arm. A portion of the structure of the transmission arm is located in the opening of the limiting member and is spaced apart from the closed end of the limiting member.

[0016] Optionally, it also includes a handle assembly, which includes a handle body, a follower part, and a rotating shaft. The rotating shaft is located between the handle body and the follower part. The follower part can apply force to the pressing plate under the drive of the handle body to make the pressing plate slide.

[0017] Optionally, it also includes an exterior panel assembly and a fixed housing, the fixed housing being disposed on the outside of the first housing, the exterior panel assembly being disposed between the handle body and the first housing and located in front of the first housing, and being able to fasten with the fixed housing and cover the first housing.

[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 providing a protrusion on the pull-out component and a transmission arm, and by setting a locking element that can hinder the movement of the protrusion in the expected direction of movement when the pull-out component is opened, and then connecting the transmission arm to the locking element, so that the movement of the transmission arm can drive the locking element to move away from the expected movement trajectory of the protrusion, the present invention provides a pull-out device with the following beneficial effects:

[0020] The pull-out device provided by this invention has a large adjustment range for the smoothness of operation and the tactile feedback. Specifically, since the second end of the pull-out component usually abuts against the protrusion when it is in the pulled-out state or in the reset state, those skilled in the art can adjust the smoothness and tactile feedback to the occupant as needed by flexibly setting the length and slope of the protrusion. At the same time, since the protrusion is set on the pull-out component, the adjustable length range of the protrusion is obviously much larger than the range of the inclined surface that can be set on the bar-shaped locking tongue in the related art, and the protrusion has a large adjustment range for the smoothness of operation and the tactile feedback.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

Detailed Implementation

[0051] 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.

[0052] 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.

[0053] 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 of the pull-out device as the front-to-back direction of the vehicle, and the pulling direction as from rear to front, with the first side as the upper side and the second side as the lower side, the pull-out device includes a base assembly 1, a pull-out component 2, an outer protective plate 3, a handle assembly 4, a fixing housing 5, and a first housing 6. The pull-out component 2 is a rectangular box-shaped container with an upper opening. The base assembly 1 is located below the pull-out component 2, and a connection is provided between the base assembly 1 and the pull-out component 2. A slide rail structure (not shown) is used to allow the pull-out component 2 to complete the pull-out action; an outer protective plate 3 is provided on the outer side of the left and right surfaces of the pull-out component 2 extending along its length; a first housing 6 is located at the front of the pull-out component 2, which is integrated with the pull-out component 2 and closes the front opening of the pull-out component 2, and has a structure that is higher than the pull-out component 2; a handle assembly 4 is provided on the upper front side of the first housing 6; a door-shaped fixing housing 5 is provided on the outer side of the first housing 6; the fixing housing 5 and the base assembly 1 are fixedly connected to other parts of the vehicle. In particular, in this embodiment, a [feature] is provided on the lower surface of the pull-out component 2. Figure 8 The diagram shows a protrusion 21 with a triangular cross-section (partially filled for clarity), and a locking member 8 that rotates with the rotation of the handle assembly 4 is provided between the base assembly 1 and the pull-out member 2. When the pull-out device is in the locked state, the locking member 8 blocks the front of the protrusion 21 so that the pull-out member 2 cannot move forward (i.e., be pulled open). When the handle assembly 4 rotates upward under the action of external force (i.e. when unlocking the pull-out device), the locking member 8 will move away from the expected trajectory of the protrusion 21, so that the pull-out member 2 can be pulled out without obstruction, thus unlocking the pull-out device.

[0054] Specifically, the handle assembly 4 in this embodiment includes, as follows: Figure 9 The shown components are a handle body 41, a rotating shaft 43, and a torsion spring 44. A second housing 9 is also fixedly installed inside the first housing 6. The rotating shaft 43 is rotatably mounted on the second housing 9 in the left-right direction of the vehicle. The torsion spring 44 is sleeved on the outer periphery of the rotating shaft 43 and abuts against the second housing 9, so that the handle body 41 can rotate around the rotating shaft 43 and can rotate upward under the action of external force. After the external force is removed, it can be reset by the elastic force of the torsion spring 44. It should be noted that the specific arrangement between the torsion spring 44 and the second housing 9 to achieve this effect is flexible and can be done by those skilled in the art, and will not be elaborated here.

[0055] Please refer to further information. Figure 10The handle assembly 4 also includes a follower part 42 connected to the rear of the handle body 41. The follower part 42 and the handle body 41 form a fixed angle. After the handle assembly 4 is assembled with the second housing 9, the handle body 41 is located on the front side of the second housing 9, and the follower part 42 passes through the second housing 9 and extends to the rear side of the second housing 9. Correspondingly, at the rear of the second housing 9, a row of vertical ribs 91 extending upward from the rear surface of the second housing 9 is provided on the position directly below the follower part 42. A sound-absorbing felt 92 is glued to the upper side of the vertical ribs 91. The sound-absorbing felt 92 is spaced apart from the follower part 42. When the handle body 41 rotates upward to a certain stroke, the follower part 42 will strike the second housing 9 through the sound-absorbing felt 92, so as to indicate that the occupant pull device of rotating the handle body 41 has been unlocked through the reaction force.

[0056] In this embodiment, to achieve the effect that the pull-out device unlocks when the follower part 42 strikes the second housing 9, as described above, Figure 10 and Figure 11 As shown, inside the first housing 6, between the first housing 6 and the second housing 9, a receiving member 7 and a transmission arm 10 are also provided. The receiving member 7 is bolted to the second housing 9 and to different parts of the first housing 6, as shown below. Figure 14 and Figure 15 The transmission arm 10 extends downward from the upper part of the pull-out device to the lower part of the pull-out device and can be hooked with the aforementioned locking member 8. The receiving member 7 is provided with a series of transmission components. The handle body 41 can apply force to these transmission components to make the transmission arm 10 move, thereby driving the locking member 8 to rotate and finally realize the locking of the pull-out device.

[0057] Specifically, please refer to the following: Figures 11 to 12 The accommodating member 7 is provided with a transmission arm 10, an elastic member 11 (a spring in this embodiment), a pressing plate 12, and two toothed transmission members 13. The transmission arm 10 is located below the elastic member 11 and is fixedly connected to the elastic member 11. The two toothed transmission members 13 are arranged on the left and right sides of the transmission arm 10. The pressing plate 12 is located in front of the transmission arm 10, the elastic member 11, and the toothed transmission members 13. More specifically, the accommodating member 7 is provided with a first limiting guide rail 14 with a V-shaped buckle end on both the left and right ends. The left and right ends of the pressing plate 12 are respectively engaged with the first limiting guide rail 14 and can move up and down along the first limiting guide rail 14. A contact block 121 is provided in the middle of the pressing plate 12. The follower part 42 of the handle assembly 4 passes through the second housing 9 and extends to the upper side of the contact block 121. When the handle body 41 rotates upward, it can apply a downward force to the contact block 121, so that the pressing plate 12 also moves downward.

[0058] Please refer to further information. Figure 13 and Figure 14The pressing plate 12 has follower posts 122 extending rearward from its rear surface on both ends. The upper part of the elastic member 11 extends out of the receiving member 7 and contacts the first housing 6 (or can be fixedly connected). The transmission arm 10 passes through the receiving member 7 along the upper and lower sides of the actual vehicle, and has a cross rib for engaging the elastic member 11 at the middle position of its upper part. The left and right surfaces of its upper part have outwardly protruding teeth. The toothed transmission member 13 is specifically cylindrical, with a central through hole 131 in its middle. A mating shaft 71 fixed on the receiving member 7 passes through it. The toothed drive member 13 is rotatably mounted on the receiving member 7 through the central through hole 131. At the same time, the toothed drive member 13 has teeth about 1 / 3 of its circumference on the end near the drive arm 10, which mesh with the upper part of the drive arm 10. The toothed drive member 13 has a lug 132 extending outward from its side surface on the end away from the drive arm 10. The lug 132 has an elongated through hole 1321 along the front-rear direction of the actual vehicle. The follower post 122 extends into the through hole 1321 and can slide along the through hole 1321. Thus, when the handle body 41 rotates upward under the action and drives the pressing plate 12 to move downward, the toothed transmission members 13 located on different sides of the transmission arm 10 will rotate in opposite directions. The transmission arm 10 will move upward under the drive of the toothed transmission members 13 and compress the elastic member 11. Similarly, when the external force applied to the handle body 41 is removed, the elastic member 11 will push the transmission arm 10 downward under the action of the elastic force, and cause the toothed transmission members 13 to return to their original position.

[0059] Preferably, the pressing plate 12 is provided with a second limiting guide rail 15 extending rearward from its rear surface. The second limiting guide rail 15 is located below the follower post 122 and has a V-shaped snap-fit ​​end. Correspondingly, the receiving member 7 is provided with a third limiting guide rail 16 having a V-shaped snap-fit ​​end that is connected to the second limiting guide rail 15. The pressing plate 12 can move up and down relative to the third limiting guide rail 16. Based on this, the first limiting guide rail 14 and the third limiting guide rail 16 work together to form a guide rail that ensures that the pressing plate 12 has a reliable up and down movement trajectory.

[0060] Similarly, on the left and right sides of the portion of the transmission arm 10 located below the accommodating member 7, there are transmission limiting guide rails 17 extending forward from the surface of the accommodating member 7. The transmission limiting guide rails 17 have V-shaped snap-fit ​​ends and snap-fit ​​with the transmission arm 10 on the lower side of the structure with tooth features on the transmission arm 10. This can also form a guide rail function similar to the aforementioned first limiting guide rail 14 and third limiting guide rail 16, ensuring the reliability of the up and down movement of the transmission arm 10.

[0061] More preferably, a limiting buckle 18 with a V-shaped buckle end is provided on the periphery of the mating shaft 71. The limiting buckle 18 extends forward from the surface of the accommodating member 7 and passes through the limiting groove 133 correspondingly provided on the toothed transmission member 13. It can fasten the toothed transmission member 13 onto the accommodating member 7 without hindering the toothed transmission member 13 from rotating on the accommodating member 7. When the toothed transmission member 13 rotates, the limiting groove 133 will rotate relative to the limiting buckle 18. When the handle body 41 rotates to the limit (i.e., the aforementioned handle body 41 collides with the first housing 6), the edge of the end of the limiting groove 133 will collide with the limiting buckle 18. The purpose of the limiting buckle 18 in this embodiment is to ensure that the toothed transmission member 13 can be stably mounted on the accommodating member 7 in the front-rear direction of the actual vehicle.

[0062] Please continue reading. Figures 14 to 16 In this embodiment, the transmission arm 10 is generally L-shaped. After passing downward through the receiving member 7, it passes backward through the first housing 6 at the lower front side and extends between the pull-out member 2 and the base assembly 1 to contact the locking member 8, and has the following characteristics: Figure 17 The L-shaped hook end 101 extending to the rear side of the first housing 6 is shown, and this hook end 101 is detachably fastened to the locking member 8. Further, in this embodiment, a U-shaped limiting member 22 is provided near the lower front part of the transmission arm 10, specifically at the front side of the transmission arm 10. The opening of the limiting member 22 is fixed to the first housing 6 with its opening facing rearward; more specifically, its open end passes through the first housing 6, has a V-shaped buckle shape, and is engaged with the first housing 6 at the rear side; the lower part of the transmission arm 10 is located inside the open end of the limiting member 22 and is spaced apart from the closed end of the limiting member 22. The limiting member 22 can limit the range of motion of the transmission arm 10.

[0063] As described above, the transmission arm 10 is connected to the locking member 8 via the hook end 101, and can apply force to the locking member 8 using the lever principle to rotate the locking member 8, thereby unlocking the pull-out device. Specifically, the locking member 8 is a V-shaped member, with its front end located above and connected to the hook end 101, and its rear end located in front of the protrusion 21, and in contact with the front end of the protrusion 21 when the pull-out device is in the locked state (e.g., ...). Figure 18 With the front end of the locking member 8 as the first end 81 and the rear end of the locking member 8 as the second end 82, when the pull-out device is engaged, the height of the first end 81 is lower than the height of the second end 82. A locking member pivot 83, arranged along the left-right direction of the actual vehicle, is fixed in the middle of the locking member 8. An auxiliary assembly 19 is provided on the lower side of the locking member 8, and the auxiliary assembly 19 is fixed on the base assembly 1 (see...). Figure 19The base assembly (with part of the base hidden to clearly show the auxiliary assembly) includes a base plate 191, a flexible member 192, a pivot support 193, a reset elastic member 194 (a spring in this embodiment) and a connector 195. The flexible member 192, the pivot support 193, the reset elastic member 194 and the connector 195 are arranged sequentially from front to back on the base plate 191. The connector 195 is a bolt used to pass through the base plate 191 and the base assembly 1 from bottom to top to fix the base plate 191 to the base assembly 1. The flexible component 192 is a lollipop-shaped rubber component located below the first end 81 and fixed to the base plate 191. The pivot support 193 is a plate disposed on the left and right sides of the lock component 8, extending upward from the surface of the base plate 191 and located behind the lock component pivot 83, for the lock component pivot 83 to rest against it. The reset elastic component 194 is located below the second end 82, with one end fixedly connected to the second end 82 and the other end fixedly connected to the base plate 191, for realizing the reset of the lock component 8. Further, in the circumferential direction of the lock component pivot 83, a portion of the lock component pivot 83 contacts the pivot support 193, and the other portion passes through the corresponding plate of the base assembly 1. This plate has a U-shaped hole 23 with an opening facing the pivot support 193 (see...). Figure 16 The locking pin 83 passes through the hole and abuts against the pin support 193, so that the locking pin 8 is rotatably disposed between the base assembly 1 and the pull-out part 2.

[0064] As described above regarding the transmission arm 10, when the handle body 41 rotates upward under the action of an external force, the transmission arm 10 will move upward; based on this, when performing the unlocking operation on the pull-out device (i.e., the transmission arm 10 moves upward), such as Figure 20 and Figure 21 As shown, the hook end 101 of the transmission arm 10 will push the first end 81 of the lock member 8 upward, causing the lock member shaft 83, which is fixedly connected to the lock member 8, to rotate, and the second end 82 to rotate downward, compressing the reset elastic member 194, and separating the rear surface of the lock member 8 from the front surface of the protrusion 21; at this time, the occupant can then grasp the handle body 41 and apply force outward, which will cause the transmission arm 10 and the pull-out member 2 to move as shown. Figure 22 The device moves forward as shown (at this time, the handle assembly 4, the first housing 6, the second housing 9 and the receiving member 7 also move forward together, not shown in the figure), thereby pulling out the pull-out member 2 to perform the operation of placing or retrieving items.

[0065] As described above, after the transmission arm 10 moves forward and separates from the locking member 8, the second end 82 will move upward under the elastic force of the reset elastic member 194 until it abuts against the lower surface of the base assembly 1 or the protrusion 21 (e.g., Figure 23Simultaneously, the first end 81 will move downwards a corresponding height based on the upward movement distance of the second end 82. Afterwards, when the occupant completes the placement or retrieval operation and pushes the pull-out piece 2 inwards, the pull-out piece 2 moves backwards under the occupant's push, and the second end 82 will again abut against the inclined lower surface of the protrusion 21 and move relative to that surface (actually, the surface is moving backwards); subsequently, at the moment when the rear surface of the second end 82 passes the lowest point of the protrusion 21 (e.g.... Figure 24 After that, the second end 82 will move upward again under the elastic force of the reset elastic member 194 and return to the height when the pull-out device is locked, and once again obstruct the expected pull-out trajectory of the protrusion 21. The first end 81 will also return to the height when the pull-out device is locked, and the hook end 101 of the transmission arm 10 will return to the lower side of the first end 81. At this point, the pull-out member 2 has been reset.

[0066] Furthermore, in this embodiment, a first feature 811 and a second feature 812 are connected on the lower surface of the first end 81 of the lock member 8. The first feature 811 is located in front of the second feature 812. The first feature 811 is a chamfer that is higher in the front and lower in the back. The second feature 812 is a rounded corner that makes the lower surface of the first end 81 concave. The purpose of setting these two features is to ensure that the transmission arm 10 can be smoothly reset.

[0067] Specifically, to ensure that the second end 82 and the protrusion 21 truly separate when the handle body 41 rotates to its travel limit, the second end 82 is often set to move downwards to the lower side of the lowest point of the protrusion 21 when the handle body 41 rotates to its travel limit. Figure 25 As shown, there is a gap d1 between the second end 82 and the lowest point of the protrusion 21. The height of the second end 82 at this time is denoted as the first abutment height, and the height of the first end 81 is denoted as the second force-bearing height. Subsequently, when the pull-out member 2 is pushed back, the second end 82 will abut against the protrusion 21 under the elastic force of the reset elastic member 194. Therefore, during the reset process, when the second end 82 abuts against the lowest point of the protrusion 21 again, the height of the second end 82 is denoted as the second abutment height, and the height of the first end 81 is denoted as the second force-bearing height. The second abutment height will be higher than the first abutment height and a first force-bearing height will exist. The height difference d2 means that the second force-bearing height will be lower than the first force-bearing height, resulting in a second height difference d3. This situation will cause the hook end 101 of the transmission arm 10 to interfere with the first end 81 during the reset process, resulting in the hook end 101 being unable to reset (i.e., unable to return to the lower side of the first end 81). Furthermore, since some occupants are accustomed to rotating the handle body 41 upward while pushing back the pull-out part 2, the hook end 101 of the transmission arm 10 will also be in an upward-curved state at this time, further increasing the risk of interference between the hook end 101 and the first end 81.

[0068] Based on this, in this embodiment, the aforementioned first feature 811 and second feature 812 are provided on the first end 81 of the lock member 8; due to the presence of the chamfered first feature 811, the thickness of the first end 81 of the lock member 8 will have the smallest value at its leading edge; such as Figure 26 As shown, when the hook end 101 of the transmission arm 10 interferes with the first end 81 during the reset process, the hook end 101 can slide smoothly into the lower side of the first end 81 along the inclined surface formed by the first feature 811 on the locking member 8. Preferably, when the hook end 101 slides into the recessed area formed by the second feature 812 on the locking member 8, the hook end 101 has completed the reset and returned to a stable hooking state with the locking member 8. In addition, when the hook end 101 slides into the recessed area formed by the second feature 812 on the locking member 8, it will also make a slight impact sound with the recessed area. This impact sound can also serve as a reminder to the occupant that the reset is complete, ensuring the occupant's operating experience.

[0069] In summary, by providing a protrusion 21 at the lower part of the pull-out member 2 and a transmission arm 10, and by providing a locking member 8 that can hinder the movement of the protrusion 21 in the expected direction of movement when the pull-out member 2 is opened, and by connecting the transmission arm 10 to the locking member 8, the movement of the transmission arm 10 can drive the locking member 8 to move away from the expected movement trajectory of the protrusion 21. This invention provides a pull-out device with the following beneficial effects:

[0070] 1. The pull-out device provided by the present invention has a large adjustment range for the smoothness of operation and the jerkiness. Specifically, since the second end 82 usually abuts against the protrusion 21 when the pull-out component 2 is in the pulled-out state or in the reset state, by flexibly setting the length and slope of the protrusion 21, those skilled in the art can adjust the smoothness and jerkiness of the movement of the pull-out component 2 to the passenger as needed. At the same time, since the protrusion 21 is a rib set at the bottom of the pull-out component 2, the settable length range of the protrusion 21 is obviously much larger than the range of the inclined surface that can be set on the strip lock tongue in the related art, and the protrusion 21 has a large adjustment range for the smoothness of operation and the jerkiness.

[0071] 2. Based on the aforementioned structure, the present invention only requires the provision of an outer trim assembly 20 (e.g., on the side of the first housing 6 away from the pull-out member 2) at the front of the pull-out device (specifically, on the side of the first housing 6 away from the pull-out member 2). Figure 6 As shown), the outer trim panel assembly 20 is fastened to the fixed housing 5 to close the first housing 6. The front of the pull-out device is always exposed except for the handle body 41, which provides a pull-out device with a hidden lock structure. Due to the use of the hidden lock, the pull-out device provided by the present invention does not have the situation of exposed strip lock tongue in the related technology, which can greatly improve the product appearance of the pull-out device.

[0072] It should be noted that the positions of components such as the handle assembly 4, locking member 8, transmission arm 10, and base assembly 1 in the above embodiments can be flexibly adjusted by those skilled in the art when arranged inside the vehicle. For example, the handle assembly 4 can also rotate around the vertical and lateral directions of the actual vehicle as the axis of rotation. In this case, the locking member 8 and the base assembly 1 are respectively arranged on the right side of the pull-out member 2. The locking member 8 is an L-shaped component that first extends along the left-right direction of the actual vehicle and then extends along the front-back direction of the actual vehicle. Furthermore, 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 with pull-out and locking requirements, such as pull-out flip ashtrays. Specifically, 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.

[0073] 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. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
