Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0050] With the development of vehicle intelligence and the improvement of users' requirements for riding comfort, electric doors are increasingly configured on vehicles. An electric door is a door that realizes automatic opening and closing through electric control.

[0051] In the related art, the automatic opening and closing of an electric vehicle door can be achieved by a door opening and closing control device. However, during the daily use of a vehicle, the mechanical transmission structure in the door opening and closing control device often corrodes, thereby reducing the service life of the door opening and closing control device.

[0052] Based on this, to solve the problem of how to extend the service life of the door opening and closing control device, the present application provides a door opening and closing control device, a door and a vehicle. The device in the present application drives a worm to drive a worm gear to rotate through a driving component, so that the worm gear moves along the axial direction of the lead screw on the lead screw to control the opening or closing of the door. Among them, the worm gear and the worm are located in the first accommodating cavity of the housing, and the first part of the lead screw is located in the first accommodating cavity, and the second part of the lead screw is located in a waterproof cover, so that the mechanical transmission components in the door opening and closing control device are isolated from the outside world, reducing the probability of the mechanical transmission components of the device coming into contact with rainwater, etc., thereby avoiding the corrosion of the mechanical transmission components and achieving the effect of extending the service life of the door opening and closing control device. The specific device is as follows:

[0053] In a first aspect of the present application, an embodiment is proposed, as Figure 1 shown in the external structure diagram of a door opening and closing control device, and Figure 2 shown in the internal structure schematic diagram of a door opening and closing control device, the device includes:

[0054] A housing 01, a first accommodating cavity is provided in the housing 01, and the housing 01 is connected to a first component;

[0055] A worm gear 02 and a worm 03 meshing with the worm gear 02, the worm gear 02 and the worm 03 are located in the first accommodating cavity;

[0056] A lead screw 04, the target end 041 of the lead screw 04 is connected to a second component, and the first bushing 17 of the worm gear 02 is threadedly sleeved on the lead screw 04;

[0057] A waterproof cover 05, the lead screw 04 includes a first part 042 located in the first accommodating cavity and a second part 043 located outside the first accommodating cavity, the waterproof cover 05 covers the outside of the second part 043, and the waterproof cover 05 completely wraps the second part 043;

[0058] A driving component 06, connected to one end of the worm 03, the driving component 06 is used to drive the worm 03 to rotate;

[0059] Among them, the first component and the second component are one of a door or a door frame, and the first component and the second component are different components.

[0060] For example, the first component can be a door or a door frame, and the second component can be a door or a door frame. When the first component is a door, the second component is a door frame; when the first component is a door frame, the second component is a door.

[0061] Reference Figure 3 Figure 3 shows a schematic structural view of a transmission component of a door opening and closing control device. The transmission component of the device in this application mainly includes a lead screw 04, a worm gear 02, and a worm 03. The worm gear 02 and the worm 03 are a mechanical device for transmitting rotational motion and rotation. The worm gear 02, also known as a helical gear, is a gear with a helical rack. The worm 03 is a cylindrical shaft that mates with the worm gear 02, and its outer surface has a linear rack that is also helical in shape and mates with the rack of the worm gear 02. The motion is transmitted between the worm gear 02 and the worm 03 through the cooperation of the helical racks. By rotating the worm 03, the worm gear 02 can be driven to rotate.

[0062] The lead screw 04 is a cylindrical part with a thread on its surface, and the inner surface of the first bushing 17 of the worm gear 02 is provided with a thread that is thread - adapted to the lead screw 04. The first bushing 17 is sleeved on the lead screw 04 through the thread. When the driving component 06 drives the worm 03 to rotate, the worm gear 02 starts to rotate under the drive of the worm 03, and then drives the first bushing 17 fixed to the worm gear 02 to rotate, causing the worm gear 02 to move along the axial direction of the lead screw 04.

[0063] Since the worm 03 and the worm gear 02 are located in the first accommodation cavity of the housing 01, when the worm gear 02 moves along the axial direction of the lead screw 04, the housing 01 will move along the axial direction of the lead screw 04 under the drive of the worm gear 02, causing the distance between the housing 01 and the target end 041 of the lead screw 04 to change. Further, the change in the distance between the housing 01 and the target end 041 will further cause the distance between the door and the door frame to change, thereby realizing the opening or closing of the door.

[0064] In an optional embodiment, the waterproof cover 05 can be wrapped around the outer side of the second part 043 of the lead screw 04 and fit with the outer side of the second part 043. The material of the waterproof cover 05 can be rubber or plastic.

[0065] In an optional embodiment, taking the first component as the door and the second component as the door frame as an example, the housing 01 can be connected to the position of the door close to the door hinge, and the target end 041 can be connected to the position of the door frame close to the door hinge.

[0066] In an optional embodiment, the driving component 06 can be a driving motor, and the output shaft of the driving motor is connected to one end of the worm 03.

[0067] The device of this embodiment drives the worm 03 through the driving component 06 to drive the worm wheel 02 to rotate, so that the worm wheel 02 moves along the axial direction of the lead screw 04 on the lead screw 04 to control the opening or closing of the vehicle door. Among them, the worm wheel 02 and the worm 03 are located in the first accommodating cavity of the housing 01, the first part 042 of the lead screw 04 is located in the first accommodating cavity, and the second part 043 of the lead screw 04 is located in the waterproof cover 05, so that the mechanical transmission components in the vehicle door opening and closing control device are isolated from the outside world, reducing the probability of the mechanical transmission components of the device coming into contact with rainwater, etc., thereby avoiding the corrosion of the mechanical transmission components and achieving the effect of extending the service life of the vehicle door opening and closing control device.

[0068] Optionally, referring to Figure 2 , the second part 043 includes a first sub-part 0431 and a second sub-part 0432, and the waterproof cover 05 includes a first waterproof cover 051 and a second waterproof cover 052;

[0069] The first sub-part 0431 is located on the side of the housing 01 close to the second component, and the first waterproof cover 051 covers the outside of the first sub-part 0431;

[0070] The second sub-part 0432 is located on the side of the housing 01 away from the second component, and the second waterproof cover 052 covers the outside of the second sub-part 0432.

[0071] To optimize the structure of the vehicle door opening and closing control device, the second part 043 of the lead screw 04 located outside the accommodating cavity can be divided into a first sub-part 0431 and a second sub-part 0432. The first sub-part 0431 and the second part 043 are respectively located on opposite sides of the housing 01. The first sub-part 0431 is located on the side of the housing 01 close to the second component, and the second sub-part 0432 is located on the side of the housing 01 away from the second component.

[0072] To improve the sealing performance of the vehicle door opening and closing control device, the waterproof cover 05 includes a first waterproof cover 051 and a second waterproof cover 052. The first waterproof cover 051 covers the outside of the first sub-part 0431, and the second waterproof cover 052 covers the outside of the second sub-part 0432.

[0073] Optionally, referring to Figure 4 The structural schematic diagram of the first waterproof cover of a vehicle door opening and closing control device shown, the first waterproof cover 051 includes a plurality of frustum side surfaces 0511, the bottom edge of each frustum side surface 0511 is connected to the bottom edge of the adjacent frustum side surface 0511, or the top edge of each frustum side surface 0511 is connected to the top edge of the adjacent frustum side surface 0511;

[0074] One end of the first waterproof cover 051 fits against the outer side surface of the target end 041;

[0075] Referring to Figure 5Schematic diagram of the waterproof cover assembly of a door opening and closing control device, where Figure 5 Only some components of the door opening and closing control device are shown. At the other end of the first waterproof cover 051, a first sealing ring 0512 is provided, and a first sealing groove 011 is provided on the inner surface of the housing 01. The first sealing ring 0512 is located in the first sealing groove 011.

[0076] When the driving device drives the worm 03 to rotate, the lengths of the first sub - part 0431 and the second sub - part 0432 will change as the worm 03 rotates. When the door is opened, the length of the first sub - part 0431 will increase, and the length of the second sub - part 0432 will correspondingly decrease; conversely, when the door is closed, the length of the first sub - part 0431 will decrease, and the length of the second sub - part 0432 will correspondingly increase. Thus, it can be seen that the first sub - part 0431 is in a state where its length is constantly changing during the operation of the door opening and closing control device.

[0077] Based on this, to ensure the waterproofness of the first waterproof cover 051, the length of the first waterproof cover 051 should also change with the elongation or shortening of the first sub - part 0431. The first waterproof cover 051 is composed of a plurality of frustum side surfaces 0511. Among them, the frustum side surface 0511 refers to the side surface of the frustum. The plurality of frustum side surfaces 0511 of the first waterproof cover 051 are connected in sequence to form the waterproof surface of the first waterproof cover 051. Among them, the bottom edges of two adjacent frustum side surfaces 0511 are connected to each other, or the top edges of two adjacent frustum side surfaces 0511 are connected to each other.

[0078] After the plurality of frustum side surfaces 0511 are connected, a structure similar to a ripple is formed on the surface of the first waterproof cover 051, so that the first waterproof cover 051 has a certain stretchability. When the two ends of the first waterproof cover 051 are subjected to tensile or pressure forces, the stretchability of this structure similar to a ripple enables the first waterproof cover 051 to elongate or contract relatively freely, so as to adapt to the elongation or shortening of the first sub - part 0431.

[0079] Reference Figure 4 , the connection of the plurality of frustum side surfaces 0511 makes the first waterproof cover 051 as a whole in a tubular shape with openings on both sides. Therefore, to ensure the airtightness of the first waterproof cover 051, one end of the first waterproof cover 051 should be fitted to the outer surface of the target end 041 to prevent liquid from entering through the opening at this end.

[0080] Meanwhile, the other end of the first waterproof cover 051 should communicate with the first accommodation cavity to prevent liquid from entering through the opening at this end. Specifically, to ensure the tightness of the connection between the first waterproof cover 051 and the first accommodation cavity, a first sealing ring 0512 should be provided at the other end of the first waterproof cover 051, and a first sealing groove 011 should be provided on the inner surface of the housing 01, with the first sealing ring 0512 located within the first sealing groove 011 to achieve a better sealing effect.

[0081] In an alternative embodiment, barbs can be provided on the target end 041 such that one end of the first waterproof cover 051 fits against the surface of the barbs, thereby preventing the first waterproof cover 051 from detaching during the telescoping process.

[0082] In an alternative embodiment, the first sealing ring 0512 can be a Figure 5 star-shaped sealing ring as shown.

[0083] Optionally, the second waterproof cover 052 is provided with a second accommodation cavity, and the second accommodation cavity is provided with an opening;

[0084] The second sub-part 0432 passes through the opening and is located within the second accommodation cavity. A second sealing ring 0521 is provided at the edge of the opening, and a second sealing groove is provided on the inner surface of the housing 01, with the second sealing ring 0521 located within the second sealing groove.

[0085] Referring to Figure 6 the schematic structural diagram of the second waterproof cover of a door opening and closing control device shown, since one end of the lead screw 04 away from the second component is in a suspended state, the second waterproof cover 052 can be a cover body with an opening only at one end, and a second accommodation cavity for accommodating the second sub-part 0432 is provided inside, thereby simplifying the structure of the second waterproof cover 052 and improving the waterproof effect of the second waterproof cover 052.

[0086] Meanwhile, to prevent liquid from entering through the opening of the second accommodation cavity, the opening can be connected to the housing 01, thereby communicating the first accommodation cavity and the second accommodation cavity. Specifically, referring to Figure 5 , a second sealing ring 0521 should be provided at the edge of the opening, a second sealing groove should be provided on the inner surface of the housing 01, and the second sealing ring 0521 should be located within the second sealing groove to achieve a better sealing effect.

[0087] In an alternative embodiment, the second sealing ring 0521 can be a Figure 5 star-shaped sealing ring as shown.

[0088] In an alternative embodiment, to further prevent the second sealing ring 0521 from detaching from the second sealing groove, a sealing ring fixing plate can also be provided at the corresponding position of the second sealing groove.

[0089] Optionally, referring to the exploded structural schematic diagram of a door opening and closing control device shown in FIG. 7, the device further includes a shock-absorbing ring 07;

[0090] One end of the worm 03 is provided with a second bushing 031. The driving member 06 includes a driving shaft corresponding to the second bushing 031. The second bushing 031 is sleeved on the driving shaft 061, and the shock-absorbing ring 07 is located between the driving shaft 061 and the second bushing 031.

[0091] The driving member 06 includes a driving shaft 061. The driving shaft 061 can open or close the door by changing its own rotation direction. One end of the worm 03 is provided with a second bushing 031. The second bushing 031 is sleeved on the driving shaft 061, thereby realizing the connection between the driving member 06 and the worm 03.

[0092] When the door switches from the open state to the closed state, the driving shaft 061 needs to change its rotation direction. When the driving shaft 061 changes its direction, it will impact the inner surface of the second bushing 031, thereby accelerating the wear of the second bushing 031 and making the connection between the second bushing 031 and the driving shaft 061 become loose. Based on this, in order to reduce the impact force of the driving shaft 061 on the second bushing 031, the door opening and closing control device of the present application is also provided with a shock-absorbing ring 07. The shock-absorbing ring 07 is located between the driving shaft 061 and the second bushing 031, thereby buffering the impact force generated by the driving shaft 061.

[0093] In an alternative embodiment, the material of the shock-absorbing ring 07 can be rubber.

[0094] In an alternative embodiment, in order to improve the power transmission efficiency between the driving shaft 061 and the worm 03, splines can be provided on the driving shaft 061, and spline holes adapted to the splines can be provided on the first bushing 17, so that the driving shaft 061 remains relatively stationary with respect to the worm 03 during rotation.

[0095] Optionally, referring to Figure 7 , the device further includes a lead screw bracket 08 and a lead screw end 09. The lead screw bracket 08 is fixedly connected to the second component, and the lead screw end 09 is connected to the target end 041;

[0096] Referring to Figure 8 the structural schematic diagram of the lead screw bracket of a door opening and closing control device shown, and Figure 9 the structural schematic diagram of the lead screw end of a door opening and closing control device shown, a first connection hole 091 is provided on the lead screw end 09, a second connection hole 081 is provided on the lead screw bracket 08, and the lead screw bracket 08 and the lead screw end 09 are connected by a first connection pin 10 arranged in the first connection hole 091 and the second connection hole 081.

[0097] To facilitate the connection between the lead screw 04 and the second component, the door opening and closing control device further includes a lead screw bracket 08 and a lead screw end 09. The lead screw bracket 08 can be used to support and fix the lead screw 04, ensuring the stability and accuracy of the lead screw 04 during movement, preventing the lead screw 04 from bending or vibrating, and maintaining normal contact between the lead screw 04 and the worm gear 02. The lead screw end 09 is used to connect the lead screw 04 to the lead screw bracket to transfer force between the lead screw 04 and the lead screw bracket 08.

[0098] In an alternative embodiment, the lead screw end 09 can be provided with a thread structure matching the thread of the lead screw 04, and the two are connected by threads.
