Detailed Description

Preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1A and 1B, the interior of the vehicle V is provided with a floor console FC, on which a storage door cover mechanism is generally provided, which opens or shields a storage space by overturning, so as to facilitate storage.

As shown in fig. 2A, when the storage space is not required, the door cover 1 is locked on the floor console FC in the first position; as shown in fig. 2B, when the storage space is required to be used, the door cover 1 is unlocked and rotates from the first position to the second position relative to the floor console FC under the assistance of the elastic structure to expose the storage space 2, and at this time, the rotation angle of the door cover 1 is smaller, so that only a part of the storage space 2 is exposed; after the opening is completed, as shown in fig. 2C, the door cover 1 can be rotated from the second position to the third position relative to the floor console FC by external force of a hand, so that the storage space 2 is completely exposed; in the rotation process, when the external force is withdrawn, the door cover 1 can be stopped at a corresponding position, namely, the door cover 1 can hover at any position between the second position and the third position, so that a user can select the opening angle of the door cover 1 according to the requirement. The door 1 is further arranged to rotate gently from the first position to the second position under the assistance of the elastic structure.

In order to achieve the above-mentioned functions, as shown in fig. 3A and 3B, an embodiment of the present utility model provides a turnover mechanism, which includes a fixing member 10 and a turnover member 20, wherein the turnover member 20 is rotatably connected to the fixing member 10 through a rotation shaft 30, so that the turnover member 20 can rotate relative to the fixing member 10.

The flip mechanism further comprises a clutch mechanism 40 arranged between the flip 20 and the mount 10 to achieve two opening phases. The clutch mechanism 40 rotates in synchronization with the rotation shaft 30 to rotate the flip member 20 from the first position to the second position in the first opening stage (i.e., the opening assisting stage), and the clutch mechanism 40 remains stationary to allow the flip member 20 to hover at any position between the second position and the third position in the second opening stage (i.e., the hover stage). In a specific embodiment, the clutch mechanism 40 includes a clutch plate 41 and a friction plate 42, and the rotating shaft 30 is fixed by a lock nut 43 after passing through shaft holes on the fixing member 10, the clutch plate 41, the friction plate 42 and the tilting member 20 in order, thereby connecting the fixing member 10 and the tilting member 20. The friction plate 42 may be provided in two, respectively, on both sides of the flipping member 20 and in close contact with the flipping member 20, so as to provide sufficient friction to the flipping member 20 in the hovering section to hover at any position between the second position and the third position.

An elastic washer 44 and a metal washer 45 may be disposed between the lock nut 43 and the turnover member 20 to prevent abnormal noise from being generated during rotation and the lock nut 43 from being loosened.

The flip mechanism further includes a drive mechanism 50 for driving the flip member 20 from the first position to the second position to complete the opening assist. In some embodiments, as shown in fig. 3C and 3D, the driving mechanism 50 is a torsion spring, which is wound on the rotating shaft 30, and one end of the torsion spring is fixedly connected to the fixing member 10, and the other end is fixedly connected to the clutch plate 41. When the turnover member 20 is locked at the first position, the torsion spring is in a compressed state, and when the turnover member 20 is unlocked, the clutch plate 41 rotates under the elastic force (i.e. pretightening force) of the torsion spring, so that the rotating shaft 30 and the turnover member 20 are driven to rotate together from the first position to the second position relative to the fixing member 10, and the opening-assisting section is completed.

In some other embodiments, the drive mechanism 50 may be a coil spring or other elastic member, so long as the power assisted opening is enabled. When the driving mechanism 50 is a coil spring, one end of the driving mechanism is fixedly connected with the fixing piece 10, the other end of the driving mechanism is wound on the rotating shaft 30, and after unlocking, the rotating shaft 30 is rotated by pretightening force, so that the turnover piece 20 and the clutch plate 41 are driven to synchronously rotate.

The flip mechanism further includes a deceleration mechanism 60 for decelerating the flip member 20 at the opening assist stage to smoothly rotate the flip member 20 from the first position to the second position. In a specific embodiment, the speed reducing mechanism 60 is a gear damping structure (for example, a silicone oil gear damping structure), which includes a gear damper 61 and a rack gear 62, the gear damper 61 is fixed on the clutch plate 41, the rack gear 62 is fixed on the fixing member 10, the gear damper 61 and the rack gear 62 are meshed with each other, when the clutch plate 41 rotates under the driving of the driving mechanism 50, the gear damper 61 and the rotating shaft 30 rotate together with the clutch plate 41, and the rack gear 62 is stationary due to being fixed on the fixing member 10, so that the gear damper generates a damping force, the rotation speed of which is slow, and then the smooth rotation of the turnover member 20 is realized. As shown in fig. 3B and 3C, the gear damper 61 may be fixed to the clutch plate 41 by a bracket 63, and in particular, the gear damper 61, the bracket 63 and the clutch plate 41 are fastened by a screw 64 and an insert 65.

In this embodiment, the rotating shaft 30 passes through the rack 62 and can rotate relative to the rack 62, i.e. the rack 62 is sleeved outside the rotating shaft 30. In other embodiments, the rotation shaft 30 may not pass through the rack 62, but the rack 62 may be disposed beside the rotation shaft 30, i.e., the rack 62 is fixed only to the fixing member 10 without being connected to the rotation shaft 30.

The positions of the rack gear 62 and the gear damper 61 can be exchanged as required, that is, the gear damper 61 is fixed on the fixing member 10, and the rack gear 62 is fixed on the clutch plate 41, thereby realizing the deceleration.

It will be appreciated that the rotational speed of the flipper 20 is determined by the magnitude of the driving force of the driving mechanism 50 and the reduction mechanism 60, and thus, the rotational speed of the flipper 20 can be adjusted by adjusting the magnitude of the driving force of the driving mechanism 50 and the gear ratio or damping type of the reduction mechanism 60. In some embodiments, as shown in fig. 3A and 3D, the fixing member 10 may be provided with a multi-stage hanging point structure 11, which includes a plurality of clamping grooves, and the compression amount of the torsion spring can be adjusted by clamping one end of the torsion spring in different clamping grooves, so as to adjust the magnitude of the driving force.

As shown in fig. 4A, the clutch plate 41 is provided with a first stop structure 411, the fixing member 10 is provided with a second stop structure 12, and as shown in fig. 4B, when the turnover member 20 rotates from the first position to the second position, the first stop structure 411 and the second stop structure 12 abut against each other, so that the clutch plate 41 is blocked by the fixing member 10 to stop rotating, and the turnover member 20 also stops at the second position. It will be appreciated that the second position is determined by the positions of the first stop structure 411 and the second stop structure 12, and by adjusting the positions of the first stop structure 411 and the second stop structure 12, the specific position of the second position can be adjusted, so as to adjust the opening angle of the opening assisting section.

In some embodiments, the first detent structure 411 may be a recess and the second detent structure 12 may be a protrusion that is received in the recess when in the second position, thereby achieving a detent. In other embodiments, the first stop structure 411 and the second stop structure 12 may be planar, and when in the second position, they fit and abut each other, so that the clutch plate 41 and the fixing member 10 interfere to achieve the stop. It will be appreciated that the first stop structure 411 and the second stop structure 12 may be other desirable structures as long as the stops are achieved.

In some embodiments, a first retaining structure 412 may be provided on the clutch plate 41, a second retaining structure 13 may be provided on the fixing member 10, the first retaining structure 412 and the second retaining structure 13 may be detachably connected, and when the clutch plate 41 rotates from the first position to the second position, the first retaining structure 412 and the second retaining structure 13 are fixedly connected, so that the clutch plate 41 is fixedly connected with the fixing member 10 and is kept in the second position; when the flip member 20 continues to rotate from the second position to the third position or from the third position to the second position, the clutch plate 41 is kept still at the second position, as shown in fig. 4C, so that the flip member 20 can rotate between the second position and the third position, and the clutch plate 41 is not influenced by the friction force of the friction plate 42 to rotate along with the flip member 20, thereby losing the hovering effect; when the flip member 20 returns to the first position from the second position, the clutch plate 41 also returns to the first position from the second position, and the first retaining structure 412 and the second retaining structure 13 are separated under the action of an external force.

In a specific embodiment, the first holding structure 412 and the second holding structure 13 are opposite magnets, and the separable connection is achieved by the attraction of the magnets. The first retaining structure 412 and the second retaining structure 13 may also be snaps and detents or other desired detachable connection structures.

With continued reference to fig. 3A and 3B, in the present embodiment, the flipping pieces 20 are provided in two, and the clutch mechanism 40, the driving mechanism 50, and the speed reducing mechanism 60 are also provided in two for connection with the two flipping pieces 20, respectively. The fixing member 10 includes a first connecting member 14 and a second connecting member 15 connected to each other, and the second holding structure 13 is located on the first connecting member 14; the second connecting piece 15 is provided with two supporting legs 151, and the rotating shaft 30 is one and is matched with the two supporting legs 151, the two overturning pieces 20, the two clutch mechanisms 40 and the two speed reducing mechanisms 60 respectively, so that the two overturning pieces 20 are connected with the two brackets 151, and the opening of the opening assisting section and the opening of the hovering section can be realized. The fixing member 10 can be manufactured more conveniently by dividing it into the first coupling member 14 and the second coupling member 15.

It will be appreciated that the number of flipper members 20 can also be increased to three, four or more as desired, and that the clutch mechanism 40, drive mechanism 50 and reduction mechanism 60 can correspondingly be increased to a corresponding number.

The rotating shaft 30 may be provided with a positioning element for positioning the position (such as the position of the supporting leg 151) of the fixing element 10 on the rotating shaft 30, so as to ensure the tolerance and the axial position of the rotating shaft 30 and the fixing element 10, thereby ensuring the tolerance and the axial position of the whole turnover mechanism. In a specific embodiment, the positioning member includes two insert slots 31, in which an insert 32 can be inserted into the insert slot 31, the two insert slots 31 are spaced apart, and the connecting portion between the fixing member 10 and the rotating shaft 30 is located between the two insert slots 31 and limited by the insert 32, so that the fixing member 10 is positioned between the two insert 32. In this embodiment, since the rack gear 62 is fixed to the leg 151 and is fitted over the outside of the rotation shaft 30, the rack gear 62 is also positioned between the two insertion pieces 32. It will be appreciated that in other embodiments, the rack 62 may not be penetrated by the shaft 30, and the positioning member does not position it directly, but rather merely positions the mount 10, and that when the rack 62 is secured to the mount 10, its position will also follow the mount 10.

The rotating shaft 30 may be provided with a clamp groove 33 for fixing the rotating shaft 30 to a clamp, so as to facilitate the installation of the turnover member 20, the clutch mechanism 40, the driving mechanism 50, the speed reducing mechanism 60, etc. with the rotating shaft 30.

Both ends of the rotation shaft 30 (i.e., the connection ends with the fixing member 10 and the turnover member 20, etc.) are made of metal materials, and the middle portion is made of plastic, so that the connection strength can be ensured on the one hand, and the cost can be reduced on the other hand. In one embodiment, the shaft 30 may be manufactured by insert molding, further reducing manufacturing costs.

The movement principle of the turnover mechanism of the utility model is as follows:

as shown in fig. 4A, in the first position, the flip mechanism is in a locked state, and the flip member 20 is locked to the fixing member 10 by a lock mechanism (not shown in the figure); after unlocking, under the drive of the driving mechanism 50, the clutch plate 41 rotates relative to the fixed part 10, so that the rotating shaft 30 is driven to rotate by the speed reducing mechanism 60, the rotating shaft 30 rotates slowly with the turnover part 20 until the first stop structure 411 abuts against the second stop structure 12, the clutch plate 41 stops rotating, and the turnover part 20 also stops rotating to reach the second position, as shown in fig. 4B; under the action of external force (such as the force of a hand), the overturning piece 20 can overcome the friction force of the friction plate 42, so as to rotate around the rotating shaft 30 continuously to a third position, as shown in fig. 4C, in the process, if the external force is removed, the overturning piece 20 can stop rotating and does not fall off due to the friction force of the friction plate 42, so as to hover at any position between the second position and the third position; when the turnover mechanism needs to be returned to the initial state, only an external force is applied to the turnover member 20, the turnover member 20 can be rotated from the third position to the second position by overcoming the friction force of the friction plate 42, then the clutch plate 41 is disconnected from the fixing member 10 by the external force, the elastic force of the driving mechanism 50 is overcome, the clutch plate 41 is rotated to the first position from the second position with the rotating shaft 30 and the turnover member 20, the process is opposite to the opening process, and after the turnover member 20 is returned to the first position, the turnover member 20 is locked by the locking mechanism, so that the turnover mechanism can be returned to the initial state.

According to the turnover mechanism provided by the embodiment of the utility model, the turnover piece 20 is enabled to rotate smoothly in the opening assisting section through the speed reducing mechanism 60, so that a beater is avoided, and the visual effect is better.

As shown in fig. 5A and 5B, another embodiment of the present utility model provides a tilting mechanism which is substantially the same as the tilting mechanism in fig. 3A in that the reduction mechanism 60 of the tilting mechanism of the present embodiment is a shaft damper (e.g., a silicone shaft damper), which is mounted on the fixed member 10 through a damper bracket 610, and the rotating shaft 30 passes through the shaft damper and damper bracket 610, and when the rotating shaft 30 rotates with the tilting member 20 from the first position to the second position relative to the fixed member 10, the shaft damper generates a damping force, thereby reducing the speed of the rotating shaft 30 and smoothly rotating the tilting member 20 from the first position to the second position, as shown in fig. 5C. The shaft damping is a reduction mechanism commonly used in the art, and the structure and principle thereof are not described herein.

In this embodiment, the driving mechanism 50 is a coil spring, one end of which is wound on the rotating shaft 30, and the other end of which is fixed on the fixing member 10, and the rotating shaft 30 is rotated by the pretightening force of the coil spring, so as to drive the turning member 20 and the clutch plate 41 to rotate from the first position to the second position.

Specifically, as shown in fig. 5B and 5D, the coil spring is mounted on the fixing member 10 through a shaft 510, that is, one end of the coil spring is wound around the rotation shaft 30 and the other end is wound around the shaft 510, and the shaft 510 is fixed to the fixing member 10 so that the coil spring is connected to the fixing member 10 and the rotation shaft 30, respectively.

It will be appreciated that in this embodiment, the coil spring may be replaced with a torsion spring or other resilient member to urge the flipper 20 from the first position to the second position. When a torsion spring is used, a multi-stage hitch point structure 11 as shown in fig. 3A may also be provided on the mount 10 to adjust the magnitude of the driving force as needed.
