Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a docking device and a vehicle. Background Art

[0002] In the related art, the connection between the vehicle body and the chassis is usually achieved through bolts. Specifically, one of the vehicle body and the chassis is provided with a threaded hole, and the other is provided with a through hole. The bolt passes through the through hole and cooperates with the threaded hole, thereby achieving the locking of the vehicle body and the chassis together through the bolts. Usually, the vehicle body and the chassis are connected by multiple bolts, wherein one bolt corresponds to one through hole and one threaded hole. During assembly, one bolt passes through the corresponding through hole and cooperates with the corresponding threaded hole. However, this arrangement causes the locking and separation operations between the vehicle body and the chassis to take a long time.

[0003] In a flying car, the flight cabin (the flight cabin can be regarded as the body or part of the body) and the chassis adopt a mode that can be freely separated and combined. The traditional connection method between the body and the chassis cannot meet the requirements of a flying car. How to achieve accurate, reliable and efficient docking between the flight cabin and the chassis is an urgent problem to be solved. Utility Model Content

[0046] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0047] like Figure 1 As shown, in one embodiment, the docking device 100 includes a first connecting component 10 and a second connecting component 20. The first connecting component 10 and the second connecting component 20 can be locked together, and after the first connecting component 10 and the second connecting component 20 are locked together, they can also be separated. The docking device 100 can be used in a vehicle to achieve the connection and separation of the vehicle body and chassis. When in use, the first connecting component 10 is connected to one of the body and the chassis, and the second connecting component 20 is connected to the other of the body and the chassis.

[0048] like Figure 2 and Figure 3 As shown, in one embodiment, the first connecting component 10 includes a first body 1 and a first limiting unit 2, wherein the first limiting unit 2 is connected to the first body 1. The second connecting component 20 includes a second body 3, a second limiting unit 4, a driving assembly 5 and a locking member 6, wherein the second limiting unit 4, the driving assembly 5 and the locking member 6 are all connected to the second body 3.

[0049] The first body 1 and the second body 3 can approach or move away from each other in the first direction; when the first body 1 and the second body 3 approach each other in the first direction, the first limiting unit 2 can cooperate with the second limiting unit 4 to prevent the first body 1 and the second body 3 from moving relative to each other on the first plane, and the angle between the first plane and the first direction is greater than or equal to 0 degrees and less than or equal to 180 degrees; the driving component 5 can drive the locking member 6 to switch between the first position and the second position; when the locking member 6 is in the first position (refer to Figure 4 ), the locking member 6 is staggered with the first body 1 in the first direction, and the first body 1 and the second body 3 can move relative to each other in the first direction; when the locking member 6 is in the second position (reference Figure 3 ), the first limiting unit 2 cooperates with the second limiting unit 4, and the locking member 6 can press the first body 1 against the second body 3 in the first direction to prevent the first body 1 and the second body 3 from moving relative to each other in the first direction.

[0050] When the docking device 100 of this embodiment is applied to a vehicle, one of the first body 1 and the second body 3 can be connected to the vehicle body, and the other of the first body 1 and the second body 3 can be connected to the chassis. Then, the vehicle body and the chassis are driven to approach each other in the first direction until the first limiting unit 2 cooperates with the second limiting unit 4. Then, the locking member 6 is driven to move by the driving assembly 5 so that the locking member 6 presses the first body 1 onto the second body 3. In this way, the vehicle body and the chassis can be quickly locked together, thereby improving the locking efficiency of the vehicle body and the chassis.

[0051] Of course, in actual use, the vehicle body and the chassis can be connected by multiple docking devices 100 to improve the connection reliability between the vehicle body and the chassis. Here, "multiple" means greater than or equal to two, and the word "multiple" has the same meaning in each embodiment and will not be repeated in the following text.

[0052] Here, “moving on the first plane” means moving along a direction parallel to the first plane.

[0053] When the locking member 6 and the first body 1 are offset in the first direction, the locking member 6 and the first body 1 will not interfere with the following actions: action one, the first body 1 and the second body 3 approach each other along the first direction to make the first limiting unit 2 cooperate with the second limiting unit 4; action two, after the first limiting unit 2 cooperates with the second limiting unit 4, the first body 1 and the second body 3 can move away from each other along the first direction to separate the first limiting unit 2 and the second limiting unit 4.

[0054] In addition, when the first limiting unit 2 cooperates with the second limiting unit 4 and the locking member 6 presses the first body 1 onto the second body 3, the first body 1 and the second body 3 are locked together.

[0055] In addition, the first body 1 and the second body 3 approaching or moving away from each other in the first direction may mean that: the first body 1 is stationary, and the second body 3 moves along the first direction to approach or move away from the first body 1; or, the second body 3 is stationary, and the first body 1 moves along the first direction to approach or move away from the second body 3; or, both the first body 1 and the second body 3 can move, wherein the first body 1 and the second body 3 can move toward each other to approach each other, and the first body 1 and the second body 3 can also move away from each other.

[0056] In an achievable implementation, the first direction is perpendicular to the first plane. In an actual application scenario, the first direction may be a vertical direction, and the first plane may be a horizontal plane.

[0057] like Figure 3 and Figure 5 As shown, in one embodiment, the first limiting unit 2 is at least a portion of the first body 1; the second limiting unit 4 is a limiting groove arranged on the second body 3; the first body 1 can extend into the limiting groove so that the position of the first body 1 on the first plane is limited by the side wall of the limiting groove.

[0058] Specifically, after the first body 1 extends into the limiting groove, the first body 1 can resist the side wall of the limiting groove, so that the first body 1 can be prevented from moving relative to the second body 3 on the first plane. Among them, the area where the first body 1 contacts the side wall of the limiting groove can be regarded as the first limiting unit 2. In addition, it should be understood that the second limiting unit 4 is a limiting groove, which actually means that the second limiting unit 4 is the side wall of the limiting groove, that is, the position of the first body 1 on the first plane is limited by the side wall of the limiting groove. Among them, the first limiting unit 2 extends into the limiting groove and contacts the side wall of the limiting groove, thereby realizing the cooperation between the first limiting unit 2 and the second limiting unit 4.

[0059] In an achievable implementation, the first body 1 is a cylindrical structure, the limiting groove is a circular groove, and the cylindrical structure and the circular groove can be loosely matched. In addition, the first limiting unit 2 can be a section of the first body 1 close to the second body 3.

[0060] It should be noted that the first limiting unit may be a section of the first body 1 close to the second body 3, and the limiting groove may be provided on the surface of the second body 3 close to the first body 1. Among them, "the surface of the second body 3 close to the first body 1" may mean: when the relative position of the first body 1 and the second body 3 is in the first state, the second body 3 is close to the surface of the first body 1. In addition, when in the first state, the first body 1 and the second body 3 are arranged at intervals, and when in the first state, if the first body 1 subsequently approaches the second body 3 along the first direction, the first limiting unit 2 can cooperate with the second limiting unit 4. In addition, when in the first state, the first body 1 and the second body 3 may be coaxial and arranged at intervals.

[0061] like Figure 3 As shown, in one embodiment, in the first direction, at least a portion of the outer surface of the first body 1 is a first guide surface 11, and the first guide surface 11 extends from the surface of the first body 1 close to the second body 3 to the surface of the first body 1 away from the second body 3; and along the direction from the second body 3 to the first body 1, the first guide surface 11 gradually approaches the outer side surface of the second body 3.

[0062] In an achievable embodiment, the first guide surface 11 may be a conical surface, and the cross-sectional radius of the first guide surface 11 gradually increases along the direction from the second body 3 to the first body 1. In this case, the first guide surface 11 may be only a part of the outer surface of the first body 1, and the outer surface of the first body 1 except the first guide surface 11 may be a cylindrical surface. The cylindrical surface is coaxially arranged with the conical surface, and the maximum radius of the conical surface is equal to the radius of the cylindrical surface. In addition, both the conical surface and the cylindrical surface are closed-loop structures.

[0063] like Figure 3 As shown, in one embodiment, in the first direction, at least a portion of the inner surface of the limit groove is a second guide surface 41, and the second guide surface 41 extends from the surface of the second body 3 close to the first body 1 to the surface of the second body 3 away from the first body 1; and along the direction from the second body 3 to the first body 1, the second guide surface 41 gradually approaches the outer side surface of the second body 3.

[0064] In a feasible implementation, the second guide surface 41 may be a conical surface, and the cross-sectional radius of the second guide surface 41 gradually increases along the direction from the second body 3 to the first body 1 .

[0065] like Figure 3As shown, in one embodiment, the first connecting component 10 also includes a guiding unit 7, which is an annular structure and is arranged around the side wall of the first body 1; the end of the guiding unit 7 facing away from the second body 3 is connected to the side wall of the first body 1, and the end of the guiding unit 7 close to the second body 3 is spaced apart from the first body 1; the first limiting unit 2 is located in the guiding unit 7 and is spaced apart from the guiding unit 7, and the second body 3 can extend into the gap between the guiding unit 7 and the first limiting unit 2; in the first direction, at least a part of the inner surface of the guiding unit 7 is a third guiding surface 71, and the third guiding surface 71 extends from the surface of the guiding unit 7 close to the second body 3 to the surface of the guiding unit 7 facing away from the second body 3; along the direction from the second body 3 to the first body 1, the third guiding surface 71 gradually approaches the first body 1.

[0066] In a feasible implementation, the third guide surface 71 may be a conical surface, and the cross-sectional radius of the third guide surface 71 gradually decreases along the direction from the second body 3 to the first body 1 .

[0067] The second body 3 can be guided by the guiding unit 7 so that when the second body 3 approaches the first body 1 along the first direction, it can gradually move to a suitable position on the first plane, thereby allowing the first body 1 to extend into the limiting groove.

[0068] In an achievable implementation, in the first direction, the first body 1 does not protrude beyond the surface of the guide unit 7 close to the second body 3 .

[0069] like Figure 3 As shown, in one embodiment, a first connecting hole 12 is provided on the surface of the first body 1 close to the second body 3; a third limiting unit 8 is provided inside the first connecting hole 12, and the third limiting unit 8 is spaced apart from the bottom surface of the first connecting hole 12; when the locking member 6 is in the second position, at least a portion of the locking member 6 is located between the third limiting unit 8 and the bottom surface of the first connecting hole 12, and is pressed on the surface of the third limiting unit 8 close to the bottom surface of the first connecting hole 12, thereby achieving the pressing of the first body 1 on the second body 3.

[0070] The surface of the first body 1 close to the second body 3 may also refer to the surface of the first body 1 close to the second body 3 when the relative positions of the first body 1 and the second body 3 are in the first state. The side wall of the first connecting hole 12 is the side wall of the first body 1.

[0071] In addition, the third limiting unit 8 is arranged in the first connecting hole 12, which can effectively prevent damage caused by collision with foreign objects, thereby increasing the service life of the docking device 100.

[0072] In addition, in this embodiment, “the locking member 6 is offset from the first body 1 in the first direction” may refer to an area where the projection of the locking member 6 and the projection of the third limiting unit 8 do not overlap in an orthographic projection on a plane perpendicular to the first direction.

[0073] like Figure 3 As shown, in one embodiment, the third limiting unit 8 is disposed on the inner side of the first connecting hole 12. In addition, the third limiting unit 8 and the first body 1 can be an integrally formed structure. Similarly, the first limiting unit 2 and the guide unit 7 can be an integrally formed structure with the first body 1.

[0074] In one embodiment, the third limiting unit 8 is an annular boss, and the third limiting unit 8 is arranged around the axis of the first connecting hole 12 . Such an arrangement is more conducive to the cooperation between the third limiting unit 8 and the locking member 6 .

[0075] like Figure 6 As shown, in one embodiment, the locking member 6 includes a connecting structure 61 and a resisting structure 62, wherein the connecting structure 61 is used to connect the driving assembly 5, and the resisting structure 62 is arranged on the side of the connecting structure 61 and can extend between the third limiting unit 8 and the bottom surface of the first connecting hole 12 to be pressed against the surface of the third limiting unit 8 close to the bottom surface of the first connecting hole 12. The connecting structure 61 and the resisting structure 62 are connected to form an L-shaped structure, and the end of the connecting structure 61 away from the resisting structure 62 is connected to the driving assembly 5.

[0076] like Figure 3 As shown, in one embodiment, the driving assembly 5 includes a driving member 51, a transmission mechanism 52 and a limiting module 53, the driving member 51 is connected to the transmission mechanism 52, and the locking member 6 is rotationally connected to the transmission mechanism 52; the driving member 51 applies a driving force along a first direction to the locking member 6 through the transmission mechanism 52; one of the limiting module 53 and the locking member 6 is provided with a limiting column 6a, and the other is provided with a sliding groove 6b; the groove wall of the sliding groove 6b can guide and limit the limiting column 6a, so that the locking member 6 can rotate relative to the transmission mechanism 52 when moving along the first direction; wherein the angle between the axis around which the locking member 6 rotates relative to the transmission mechanism 52 and the first direction is greater than 0 degrees and less than 180 degrees. Such a setting can reduce the number of parts and components, and reduce the cost and assembly difficulty of the docking device 100.

[0077] In an achievable implementation, the sliding groove 6b is provided on the locking member 6, and the limiting column 6a is provided on the limiting module 53. In addition, the axis around which the locking member 6 rotates relative to the transmission mechanism 52 is perpendicular to the first direction, and the axis around which the locking member 6 rotates relative to the transmission mechanism 52 is parallel to the axis of the limiting column 6a.

[0078] like Figure 3As shown, in one embodiment, the transmission mechanism 52 is a screw transmission mechanism; the driving member 51 is connected to the screw 521 of the screw transmission mechanism, and the locking member 6 is connected to the nut 522 of the screw transmission mechanism. The driving member 51 applies force to the nut 522 through the screw 521, so that the nut 522 moves in the first direction, and then applies force in the first direction to the locking member 6. Among them, the axis of the screw 521 is parallel to the first direction. When working, the driving member 51 applies force to the screw 521, so that the screw 521 rotates around its own axis, and then drives the nut 522 to move in the first direction. In addition, the driving member 51 can be a device such as a rotary motor that can drive an object to rotate.

[0079] In a feasible implementation, when the driving member 51 is a rotary motor, the main shaft of the rotary motor and the screw 521 may be an integrated structure, which makes it easier to assemble the docking device 100 .

[0080] like Figure 5 and Figure 7 As shown, in one embodiment, a first guide structure 31 is provided on the second body 3, and a second guide structure 523 is provided on the nut 522. The first guide structure 31 cooperates with the second guide structure 523 to guide the movement of the nut 522 along the first direction.

[0081] In a feasible embodiment, the first guide structure 31 is a guide groove arranged on the second body 3, wherein the guide groove extends along the first direction, and the second guide structure 523 is a guide block arranged on the side of the nut 522, wherein the guide block is located in the guide groove and can extend along the length direction of the guide groove.

[0082] like Figure 3 As shown, in one embodiment, one end of the screw rod 521 away from the driving member 51 is connected to the limit module 53, and the screw rod 521 can rotate around its own axis relative to the limit module 53.

[0084] like Figure 3 As shown, in one embodiment, a plurality of locking members 6 are provided, and each locking member 6 is evenly arranged around the axis of the screw rod 521. Each locking member 6 is connected to the nut 522 in the same manner, and each locking member 6 can simultaneously press the first body 1 onto the second body 3, so that the pressing effect on the first body 1 can be improved, thereby making the connection between the first body 1 and the second body 3 more firmly.

[0085] like Figure 8 As shown, in one embodiment, the limiting module 53 is provided with an avoidance hole 531, and the avoidance hole 531 penetrates the limiting module 53 along the first direction; the locking member 6 is penetrated in the avoidance hole 531; one end of the locking member 6 protrudes out of the surface of the limiting module 53 close to the first body 1, so as to be used to press the first body 1 onto the second body 3; the other end of the locking member 6 protrudes out of the surface of the limiting module 53 away from the first body 1, so as to connect the transmission mechanism 52.

[0089] like Figures 3 to 5 As shown, in one embodiment, the second body 3 is provided with a second connection hole 32, and the second limiting unit 4 is a part of the second connection hole 32; the first body 1 can extend into the second connection hole 32, so that the position of the first body 1 on the first plane is limited by the side wall of the second connection hole 32; the locking member 6, the transmission mechanism 52 and the limiting module 53 are all arranged in the second connection hole 32, so that the second connection component 20 can be more compact. Any one of the three components of the locking member 6, the transmission mechanism 52 and the limiting module 53 is arranged in the second connection hole 32, which can mean that the component is completely located in the second connection hole 32, or it can mean that a part of the component is located in the second connection hole 32, and the other part is located outside the second connection hole 32.

[0090] In addition, in one embodiment, the second connection hole 32 penetrates the second body 3 along the first direction, and the driving member 51 is disposed outside the second connection hole 32. The driving member 51 is disposed outside the second connection hole 32, which may mean that the driving member 51 is completely disposed outside the second connection hole 32, or that a portion of the driving member 51 is located inside the second connection hole 32, and another portion is located outside the second connection hole 32.

[0091] like Figure 4 and Figure 5 As shown, in one embodiment, along the direction from the first body 1 to the second body 3, the second connecting hole 32 includes a first hole 321, a second hole 322 and a third hole 323 which are connected in sequence; the aperture of the first hole 321 is larger than the aperture of the second hole 322, so as to form a first step surface 324 between the first hole 321 and the second hole 322; the aperture of the third hole 323 is larger than the aperture of the second hole 322, so as to form a second step surface 325 between the second hole 322 and the third hole 323; the second limiting unit 4 is the first hole 321, and the locking member 6 can press the first body 1 on the first step surface 324; the inner wall of the second hole 322 is provided with a third step surface 326; the limiting module 53 is connected to the third step surface 326; at least a part of the transmission mechanism 52 is located between the second step surface 325 and the locking member 6; the third hole 323 penetrates to the surface of the second body 3 away from the first plate body, and the driving member 51 is connected to the transmission mechanism 52 from the third hole 323.

At this time, the inner surface of the receiving groove 327 in the first direction is the third step surface 326.

[0093] In addition, when the limiting module 53 is placed on the third step surface 326, the limiting module 53 does not protrude from the first step surface 324 along the direction from the second hole 322 to the first hole 321. This can prevent the limiting module 53 from interfering with the movement of the first body 1.

[0094] In addition, in the direction from the second hole 322 to the first hole 321, the locking member 6 and the transmission mechanism 52 do not protrude from the surface of the second body 3 close to the first body 1. This can effectively prevent the locking member 6 and the transmission mechanism 52 from being collided, thereby increasing the service life of the docking device 100.

[0095] It should be noted that the second limiting unit 4 is the first hole 321 , which actually means that the second limiting unit 4 is the side wall of the first hole 321 . Moreover, the above-mentioned limiting groove is the first hole 321 .

[0096] “The driving member 51 is connected to the transmission mechanism 52 at the third hole 323 ” may mean that the driving member 51 extends from the third hole 323 into the second connection hole 32 to connect with the transmission mechanism 52 , or may mean that the transmission mechanism extends from the third hole 323 to the second connection hole 32 to connect with the driving member 51 .

[0099] The first drainage hole may be a portion of the avoidance hole 531 and / or a portion of the spacing area between adjacent connecting arms 533 ; the second drainage hole may be a portion of the mounting groove 524 .

[0100] like Figure 3 As shown, in one embodiment, the driving member 51 is installed on the surface of the second body 3 facing away from the first body 1 (defined as the first surface), and the second connecting component 20 also includes a sealing cover 91 and a sealing gasket 92.

The sealing gasket 92 is arranged between the main shaft of the driving member 51 and the sealing cover 91 so as to fill the gap between the main shaft of the driving member 51 and the sealing cover 91, thereby realizing the sealing between the main shaft of the driving member 51 and the sealing cover 91.

[0101] It should be understood that the above-mentioned related settings can also be replaced by other methods, such as:

When in use, the first driving unit can drive the resisting structure 62 of the locking member 6 to move between the third limiting unit 8 and the bottom surface of the first connecting hole 12, and can reversely drive the resisting structure 62 to move out of the space between the third limiting unit 8 and the bottom surface of the first connecting hole 12; when the resisting structure 62 is located between the third limiting unit 8 and the bottom surface of the first connecting hole 12, the second driving unit can drive the resisting structure 62 to move close to the third limiting unit 8 to press the first body 1 against the second body 3, and the second driving unit can also reversely drive the resisting unit to move the resisting unit away from the third limiting unit 8.
