DETAILED DESCRIPTION

[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] According to one embodiment of the present application, a composite motion device is provided. Figures 1 to 10 As shown, the composite motion device comprises a connecting rod mechanism, a bearing mechanism 2 and a driving mechanism. Part of the connecting rod mechanism is suitable for connecting with a fixed device. The bearing mechanism 2 is rotationally connected with another part of the connecting rod mechanism. The driving mechanism is respectively connected to the connecting rod mechanism and the bearing mechanism 2, and the driving mechanism can drive the bearing mechanism 2 to move linearly relative to the fixed device, and the driving mechanism can also drive the bearing mechanism 2 to rotate relative to the fixed device.

[0044] In this example, the fixed device can be a seat, a part of the connecting rod mechanism is connected to the fixed device, and the other part of the connecting rod mechanism is connected to the supporting mechanism 2. The driving mechanism can drive the other part of the connecting rod mechanism to move linearly relative to the fixed device, that is, the connecting rod mechanism can be retracted or unfolded. Since the supporting mechanism 2 is connected to the other part of the connecting rod mechanism, the supporting mechanism 2 is driven to move linearly relative to the fixed device. The driving mechanism can also drive the supporting mechanism 2 to rotate relative to the fixed device, that is, to rotate relative to the connecting rod mechanism. The composite motion device of the present application can drive the supporting mechanism 2 to move linearly relative to the fixed device through a driving mechanism, and can also drive the supporting mechanism 2 to rotate relative to the fixed device, so as to simplify the structure of the composite motion device, make the structure of the composite motion device more compact, save installation space, and reduce costs.

[0045] The bearing mechanism 2 is suitable for installing a target product, such as a display screen 1. The driving mechanism can drive the bearing mechanism 2 to rotate relative to the fixed device, that is, it can adjust the rotation of the display screen 1 to adjust the pitch angle of the display screen 1. The driving mechanism can drive the connecting rod mechanism to move relative to the fixed device, so that the connecting rod mechanism can be expanded or retracted, and the bearing mechanism 2 is connected to the connecting rod mechanism. That is, when the connecting rod mechanism is in the expanded state, the bearing mechanism 2 can be extended; when the connecting rod mechanism is in the retracted state, the bearing mechanism 2 can be retracted. Therefore, the display screen 1 can be extended or retracted by adjusting the connecting rod mechanism to improve the convenience of the display screen 1 when in use.

[0046] In this example, when the driving mechanism is in transmission connection with the connecting rod mechanism, the driving mechanism can drive the connecting rod mechanism to be unfolded or retracted. When the driving mechanism is in transmission connection with the supporting mechanism 2, the driving mechanism can drive the supporting mechanism 2 to rotate.

[0047] When the driving mechanism is in transmission connection with the connecting rod mechanism, the driving mechanism is disconnected from the supporting mechanism 2. When the driving mechanism is in transmission connection with the supporting mechanism 2, the driving mechanism is disconnected from the connecting rod mechanism. Thus, the connecting rod mechanism and the supporting mechanism 2 can be prevented from affecting each other. That is, when the composite motion device is in operation, the driving mechanism is firstly in transmission connection with the connecting rod mechanism, the driving mechanism drives the connecting rod mechanism to be in the unfolded state, and then the driving mechanism is in transmission connection with the supporting mechanism 2 to drive the supporting mechanism 2 to rotate.

[0048] In an example, Figures 1 to 4 As shown, the connecting rod mechanism includes a first connecting rod 27, a second connecting rod 6, a third connecting rod 25 and a fourth connecting rod 11 connected end to end in sequence. The first connecting rod 27 is suitable for connecting to the fixing device, and the supporting mechanism 2 is rotatably connected to the third connecting rod 25.

[0049] like Figure 1 and Figure 2 As shown, the connecting rod mechanism includes a first connecting rod 27, a second connecting rod 6, a third connecting rod 25 and a fourth connecting rod 11. The first connecting rod 27, the second connecting rod 6, the third connecting rod 25 and the fourth connecting rod 11 are connected in rotation in sequence end to end to form a four-link structure. The first connecting rod 27 and the third connecting rod 25 are arranged opposite to each other, and the first connecting rod 27 is provided with a connecting portion, which is suitable for connecting and fixing equipment. For example, the first connecting rod 27 is fixedly connected to the seat back through the connecting portion, and the first connecting rod 27 can be connected to the seat back through fasteners such as studs or bolts. The third connecting rod 25 is provided with a second connecting portion 252, and the bearing mechanism 2 is rotatably connected to the second connecting portion 252 of the third connecting rod 25.

[0050] In this example, if Figure 4 As shown, the second connecting rod 6 and the fourth connecting rod 11 are arranged opposite to each other, and the ends of the second connecting rod 6 and the fourth connecting rod 11 are respectively connected to the opposite ends of the first connecting rod 27 and the opposite ends of the third connecting rod 25. For example, the fourth connecting rod 11 can be rotatably connected to the first connecting rod 27 and the third connecting rod 25 by rivet bolts 7, and washers 8 are also arranged on the rivet bolts 7 to improve the stability of the connection.

[0051] The second connecting rod 6 can also be rotatably connected to the first connecting rod 27 and the third connecting rod 25 by the rivet bolts 7. Of course, the second connecting rod 6 and the fourth connecting rod 11 can also adopt other rotating connection structures, which can be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0052] like Figure 4As shown, in this example, the fourth connecting rod 11 can be a rod body or a plate body structure, and the fourth connecting rod 11 is provided with two, and the two first connecting rods 27 are respectively connected to the opposite sides of the third connecting rod 25 to improve the stability of the third connecting rod 25. The second connecting rod 6 can be a frame structure, and the two sides of the frame are respectively rotatably connected to the opposite sides of the third connecting rod 25 to improve the stability of the third connecting rod 25. Alternatively, the second connecting rod 6 can also be two rod bodies or plate bodies. Of course, the specific structures of the second connecting rod 6 and the fourth connecting rod 11 can be determined by those skilled in the art according to actual conditions, and are not specifically limited here.

[0053] like Figure 4 As shown, in this example, the display screen 1 can be connected to the supporting mechanism 2 through the second fastener 5. For example, the second fastener 5 can be a bolt-nut structure, one end of the bolt is fixed to the display screen 1, and the other end of the bolt is passed through the supporting mechanism 2 and is screwed with a nut to fix the display screen 1. Among them, multiple second fasteners 5 can be provided to improve the stability of the connection of the display screen 1. For example, two, three or four can be provided. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0054] like Figure 2 and Figure 4 As shown, the third connecting rod 25 is provided with a second connecting portion 252, and the supporting mechanism 2 can be rotatably connected to the second connecting portion 252. For example, the second connecting portion 252 can be a perforated structure, and the supporting mechanism 2 can be rotatably connected to the second connecting portion 252 by a rivet bolt 7, so that the supporting mechanism 2 can rotate around the third connecting rod 25. The second connecting portion 252 is located in the middle of the third connecting rod 25, and connecting holes are respectively provided on two opposite sides of the second connecting portion 252, and the connecting holes on both sides are used to connect the second connecting rod 6 and the fourth connecting rod 11 respectively.

[0055] In one example, the driving mechanism can drive the third connecting rod 25 to move closer to or away from the first connecting rod 27 to drive the supporting mechanism to move linearly relative to the fixing device, and the driving mechanism can also drive the supporting mechanism 2 to rotate relative to the third connecting rod 25 .

[0056] For example, Figure 2 As shown, the driving mechanism can drive the third connecting rod 25 to rotate away from the first connecting rod 27. That is, the third connecting rod 25 moves linearly away from the fixing device relative to the fixing device, so that the connecting rod mechanism is in an expanded state. Figure 1 As shown, the driving mechanism can also drive the third connecting rod 25 to rotate close to the first connecting rod 27. That is, the third connecting rod 25 moves linearly close to the fixing device relative to the fixing device, so that the connecting rod mechanism is in the storage state.

[0057] In this example, if Figure 3As shown, the driving mechanism can also drive the supporting mechanism 2 to rotate. That is, after the driving mechanism drives the connecting rod mechanism to be in the unfolded state, the driving mechanism can be connected with the supporting mechanism 2 to drive the supporting mechanism 2 to rotate, thereby adjusting the pitch angle of the display screen 1.

[0058] In one example, the driving mechanism includes a first transmission member, a second transmission member, a third transmission member and a fourth transmission member. The first transmission member can be connected to the second transmission member to drive the third connecting rod 25 to move closer to or away from the first connecting rod 27. The third transmission member can be connected to the fourth transmission member to drive the supporting mechanism 2 to rotate.

[0059] Wherein, when the first transmission member is in transmission connection with the second transmission member, the third transmission member is disconnected from the fourth transmission member, and when the third transmission member is in transmission connection with the fourth transmission member, the first transmission member is disconnected from the second transmission member.

[0060] In this example, when the first transmission member is in transmission connection with the second transmission member, the driving mechanism can drive the third connecting rod 25 to move closer to or away from the first connecting rod 27. At this time, the third transmission member and the fourth transmission member are in a disconnected state. When the third transmission member and the fourth transmission member are in transmission connection with each other, the driving mechanism can drive the supporting mechanism 2 to rotate. At this time, the first transmission member and the second transmission member are in a disconnected state. So that the driving mechanism can sequentially drive the first connecting rod 27 to move relative to the fixed device and drive the supporting mechanism 2 to rotate.

[0061] In an example, Figures 4 to 9 As shown, the first transmission member includes a first gear 16, and the second transmission member includes a second gear 12. The first gear 16 and the second gear 12 are arranged on the third connecting rod 25, and at least one of the first gear 16 and the second gear 12 has a first tooth portion and a first relief portion arranged in a circumferential direction. Through the first tooth portion and the first relief portion, the first gear 16 and the second gear 12 can switch the transmission connection or disconnection between the driving mechanism and the connecting rod mechanism.

[0062] like Figure 4 and Figure 5 As shown, in this example, when the first gear 16 and the second gear 12 are meshed, the first gear 16 can drive the second gear 12 to rotate, thereby driving the third wheel connecting rod to rotate in a direction away from the first connecting rod 27, so that the connecting rod mechanism is in an expanded state, or driving the third wheel connecting rod to rotate in a direction close to the first connecting rod 27, so that the connecting rod is in a retracted state.

[0063] In this example, when the first tooth portion is engaged with the first gear 16 or the second gear 12, the first transmission member can be transmission-connected with the second transmission member, and when the first vent portion corresponds to the first gear 16 or the second gear 12, the first transmission member is disconnected from the second transmission member.

[0064] When the first gear 16 is provided with a first tooth portion and a first relief portion, the first tooth portion can mesh with the second gear 12, or the first relief portion corresponds to the second gear 12. When the second gear 12 is provided with a first tooth portion and a first relief portion, the first tooth portion can mesh with the first gear 16, or the first relief portion corresponds to the first gear 16.

[0065] Alternatively, the first gear 16 and the second gear 12 are both provided with a first tooth portion and a first relief portion. The first tooth portion of the first gear 16 can mesh with the first tooth portion of the second gear 12. The first relief portion of the first gear 16 can correspond to the second gear 12.

[0066] like Figure 6 As shown, when the teeth of the first gear 16 and the teeth of the second gear 12 are meshed and connected, the driving mechanism and the connecting rod mechanism can be switched to be in transmission connection, and the driving mechanism can drive the connecting rod mechanism to extend and retract.

[0067] like Figure 8 As shown, when the venting portion of the first gear 16 corresponds to the second gear 12, the first gear 16 and the second gear 12 are disconnected. That is, the driving mechanism is disconnected from the connecting rod mechanism, and at this time, the driving mechanism can be connected to the supporting mechanism 2 in a transmission manner.

[0068] In this example, if Figure 6 As shown, the second gear 12 may be a fan-shaped structure, and a first tooth portion is provided on the arc surface of the fan. Or the first gear 16 and the second gear 12 both have a first tooth portion and a first relief portion. That is, the first gear 16 and the second gear 12 are both incomplete gears.

[0069] In an example, Figure 4 , Figure 7 and Fig. 9 As shown, the third transmission member includes a third gear 19, and the fourth transmission member includes a fourth gear 3. The third gear 19 is arranged on the third connecting rod 25, and the fourth gear 3 is arranged on the supporting mechanism 2. At least one of the third gear 19 and the fourth gear 3 has a circumferentially arranged second tooth portion and a second relief portion.

[0070] In this example, if Figure 4As shown, the third gear 19 is disposed on the third connecting rod 25. The supporting mechanism 2 is also fixedly connected with the fourth gear 3. For example, the fourth gear 3 can be fixedly connected to the supporting mechanism 2 by a first fastener 4 such as a bolt or a stud. The third gear 19 can be meshed with the fourth gear, and the third gear 19 can drive the fourth gear 3 to rotate, thereby driving the supporting mechanism 2 to rotate.

[0071] In this example, when the second toothed portion is meshed with the third gear 19 or the fourth gear 3, the third transmission member can be transmission-connected with the fourth transmission member, and when the second relief portion corresponds to the third gear 19 or the fourth gear 3, the third transmission member is disconnected from the fourth transmission member. Through the second toothed portion and the second relief portion, the third gear 19 and the fourth gear 3 can switch the driving mechanism to be transmission-connected or disconnected with the supporting mechanism.

[0072] When the second tooth portion is engaged with the third gear 19 or the fourth gear 3, the third transmission member can be connected to the fourth transmission member in transmission, and when the second vent portion corresponds to the third gear 19 or the fourth gear 3, the third transmission member is disconnected from the fourth transmission member.

[0073] When the third gear 19 is provided with a second tooth portion and a second relief portion, the second tooth portion can mesh with the fourth gear 3, or the second relief portion corresponds to the fourth gear 3. When the fourth gear 3 is provided with a second tooth portion and a second relief portion, the second tooth portion can mesh with the third gear 19, or the second relief portion corresponds to the third gear 19.

[0074] Alternatively, the third gear 19 and the fourth gear 3 are both provided with a second tooth portion and a second relief portion. That is, the third gear 19 and the fourth gear 3 are both incomplete gears. Alternatively, the fourth gear 3 can also be provided with a fan-shaped structure, and a second tooth portion is provided on the arc surface of the fan-shaped structure. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here. The first tooth portion of the third gear 19 can mesh with the first tooth portion of the fourth gear 3. The first relief portion of the third gear 19 can correspond to the fourth gear 3.

[0075] like Fig. 9 As shown, the toothed portion of the third gear 19 meshes with the toothed portion of the fourth gear 3, and the third gear 19 can drive the fourth gear 3 to rotate. That is, the driving mechanism can be connected to the supporting mechanism 2 in a transmission manner. Figure 7 As shown, when the vented portion of the third gear 19 corresponds to the fourth gear 3, the third gear 19 is disconnected from the fourth gear 3, that is, the driving mechanism is disconnected from the supporting mechanism 2. At this time, the driving mechanism is in transmission connection with the connecting rod mechanism.

[0076] In an example, Figures 6 to 9As shown, when the first gear 16 is meshed with the second gear 12, the third gear 19 is disengaged from the fourth gear 3. When the third gear 19 is meshed with the fourth gear 3, the first gear 16 is disengaged from the second gear 12.

[0077] In this example, if Figure 6 and Figure 7 As shown, the first gear 16 is meshed with the second gear 12, and the third gear 19 is disconnected from the fourth gear 3. At this time, the driving mechanism is in transmission connection with the connecting rod mechanism, and the driving mechanism can drive the connecting rod mechanism to extend and retract.

[0078] like Figure 8 and Fig. 9 As shown, the first gear 16 and the second gear 12 are disconnected, and the third gear 19 is engaged with the fourth gear 3. At this time, the driving mechanism is in transmission connection with the supporting mechanism 2, and the driving mechanism can drive the supporting mechanism 2 to rotate.

[0079] In this example, the effects of the first gear 16 and the second gear 12, as well as the third gear 19 and the fourth gear 3, these two sets of gears can also be achieved through the curve shape of the cam slot, that is, the transmission connection or disconnection of the two cams can be achieved through the cam structure to switch the transmission connection between the driving mechanism and the connecting rod mechanism or the supporting mechanism 2. In addition, the extension or storage of the connecting rod mechanism can also be achieved through the screw nut transmission, that is, the nut is screwed to the screw, and the nut is driven to rotate through the driving mechanism, thereby driving the screw to move, thereby driving the third connecting rod 25 to move away from or toward the first connecting rod 27. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0080] In an example, Figure 4 and Figure 5 As shown, the driving mechanism includes a first transmission rod 17 , the first transmission rod 17 is rotatably connected to the third connecting rod 25 , and the first transmission member and the third transmission member are fixedly sleeved on the first transmission rod 17 respectively.

[0081] like Figure 4 and Figure 5 As shown, in this example, the driving mechanism includes a first transmission rod 17. The first transmission member includes a first gear 16, and the third transmission member includes a third gear 19. The first gear 16 and the third gear 19 are both fixedly sleeved on the first transmission rod 17. The first transmission rod 17 can synchronously drive the first gear 16 and the third gear 19 to rotate.

[0082] In this example, when the connecting rod mechanism is extended, the first gear 16 is meshed and connected with the second gear 12, and the third gear 19 is disconnected from the fourth gear 3. When the first transmission rod 17 rotates, it can drive the first gear 16 and the third gear 19 to rotate, and the first gear 16 can drive the second gear 12 to rotate, thereby driving the third connecting rod 25 to extend. The third gear 19 is disconnected from the fourth gear 3, that is, the third gear 19 is idle.

[0083] When the connecting rod mechanism is in the extended state, the first transmission rod 17 continues to rotate, the first gear 16 and the second gear 12 are disconnected, and the third gear 19 is engaged with the fourth gear 3. When the first transmission rod 17 rotates, it can drive the third gear 19 to drive the fourth gear 3 to rotate, thereby driving the supporting mechanism 2 to rotate.

[0084] When the connecting rod mechanism needs to be stored, the first transmission rod 17 reverses and first drives the bearing mechanism 2 to rotate to the initial position. The first transmission rod 17 continues to rotate, the third gear 19 and the fourth gear 3 are disconnected, and the first gear 16 and the second gear 12 are engaged, thereby driving the third connecting rod 25 to be stored.

[0085] In this example, if Figure 4 and Fig.10 As shown, the third connecting rod 25 is provided with a first connecting portion 251, and the first transmission rod 17 is rotatably connected to the first connecting portion 251. For example, the first connecting portion 251 is provided with a perforated structure, the first transmission rod 17 is penetrated in the perforated structure, and a card 9 is provided at the end of the first transmission rod 17 to limit the position, for example, the card 9 can be an E-shaped retaining spring, etc. The first gear 16 and the third gear 19 can be fixed on the first transmission rod 17 by the bayonet 15 and the square key 14. Alternatively, the first gear 16 and the third gear 19 can also be connected to the first transmission rod 17 in other ways, which can be determined by those skilled in the art according to the actual situation, and are not specifically limited here.

[0086] In an example, Figure 4 and Figure 5 As shown, the driving mechanism includes a driving motor 23, and the driving motor 23 can drive the first transmission member and the third transmission member to rotate. The first transmission member includes a first gear 16, and the third transmission member includes a third gear 19 to rotate. The driving motor 23 can drive the first gear 16 and the third gear 19 to rotate.

[0087] like Figure 4 and Figure 5 As shown, the first transmission rod 17 is sleeved with the sixth gear 18.

[0090] In this example, only one driving motor 23 is required to drive the connecting rod mechanism to extend or retract, and also to drive the supporting mechanism 2 to rotate, thereby reducing manufacturing costs, reducing noise, and saving installation space.

[0091] In an example, Figure 4 As shown, the compound motion device further includes a second transmission rod 13, the second transmission rod 13 is connected to the third connecting rod 25, and the second gear 12 is fixedly sleeved on the second transmission rod 13.

The second gear 12 can drive the second transmission rod 13 to rotate, so as to drive the fifth gear 10 to rotate.

[0093] like Figure 4 and Figure 5 As shown, in this example, two fifth gears 10 can be provided, which are respectively provided at both ends of the second transmission rod 13 , and third tooth portions 271 are correspondingly provided on opposite sides of the first connecting rod 27 to improve the rotation stability of the third connecting rod 25 .

[0094] In this example, one end of the fourth connecting rod 11 can be rotatably sleeved on the second transmission rod 13 to be rotatably connected to the third connecting rod 25. By connecting one end of the fourth connecting rod 11 to the second transmission rod 13, the connection structure can be made more compact.

[0095] like Figure 3 and Figure 4 As shown, in this example, the fifth gear 10 is fixedly sleeved on the second transmission rod 13, and the fifth gear 10 can be clamped and fixed by a card 9. The first connecting rod 27 is provided with a third tooth portion 271, and the third tooth portion 271 can mesh with the fifth tooth portion. When the first gear 16 drives the second gear 12 to rotate, it can drive the fifth gear 10 to rotate around the third tooth portion 271, so that the third connecting rod 25 can be driven to rotate more smoothly and stably.

[0096] In this example, the fifth gear 10 may be an incomplete gear, or the fifth gear 10 may be a fan-shaped structure. Those skilled in the art may determine the structure according to actual conditions, and no specific limitation is made here.

[0097] According to another embodiment of the present application, a vehicle is provided. It includes a display screen 1, and a composite motion device of the above embodiment. The composite motion device can be used to drive the display screen 1 to move, and the display screen 1 is installed on a supporting mechanism 2, and the composite motion device can drive the display screen 1 to extend or rotate. The composite motion device includes a connecting rod mechanism, a supporting mechanism 2 and a driving mechanism. The connecting rod mechanism has an expanded state and a stored state, and the supporting mechanism 2 is rotatably connected to the connecting rod mechanism. The driving mechanism is transmission-connected to the connecting rod mechanism, or is transmission-connected to the supporting mechanism 2. Therefore, the connecting rod mechanism can be driven to move between the expanded state and the stored state by a driving mechanism, and can also drive the supporting mechanism 2 to rotate, which simplifies the structure of the composite motion device, makes the structure of the composite motion device more compact, saves installation space, and reduces costs.

[0101] In this example, the sensor can sense the opening or closing of the door. That is, when the door is opened, the sensor sends a door opening signal, the drive mechanism operates, and the connecting rod mechanism is in a retracted state, thereby providing a larger space for passengers and facilitating passengers to get on or off the vehicle. When the door is closed, the sensor sends a door closing signal, the drive mechanism operates, and the connecting rod mechanism is in an extended state, so that the display screen 1 can be close to the passenger, and the camera can capture the position of the face to adjust the pitch angle of the display screen 1 to achieve a comfortable viewing angle.

[0102] In one example, the composite motion device of the present application can also be installed in other positions, such as the co-pilot position or the roof screen. The carrying mechanism 2 can also be installed with other target products, such as mobile phones, computer monitors, etc. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.
