Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a corner protection device and a vehicle. Background Technology

[0002] The tailgate is a component of a car, serving a supporting and protective function by sealing the trunk. It's typically mounted on top of the trunk via a hinge and is usually manually or electrically operated. To use it, the tailgate is flipped up to open the trunk for loading and unloading. However, when walking around the car with the tailgate flipped up, the user's head is likely to hit the sharp corner of the tailgate, which, being made of hard plastic, can cause injury. Current technology often addresses this by increasing the tailgate opening and raising the position of the sharp corner. However, even with the tailgate designed to open to its maximum permissible angle, a certain risk of head injury still exists. Summary of the Invention

[0003] The purpose of this invention is to provide a corner protection device and vehicle that can protect users from injury without affecting the opening and closing of the tailgate.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Corner protection devices include:

[0006] case;

[0007] A protective head is located outside the housing, and the protective head has a wrapping cavity;

[0008] The connecting rod is connected to the protective head;

[0009] A drive assembly, located within the housing, is pulsatorically connected to the connecting rod. The drive assembly is configured to selectively drive the connecting rod to first move along the axial direction of the connecting rod in a first translational direction and then rotate about the axial direction of the connecting rod in a first rotational direction, or to first rotate about the axial direction of the connecting rod in a second rotational direction and then move along the axial direction of the connecting rod in a second translational direction. The first translational direction is opposite to the second translational direction, and the first rotational direction is opposite to the second rotational direction.

[0010] As an optional technical solution for corner protection devices, the drive assembly includes a drive component, a rotating component, and a guide component. The drive component is pulsatorically connected to the rotating component, and the rotating component is rotatably connected to the housing. The connecting rod has an external thread, and the rotating component has an internal thread. The rotating component is threadedly connected to the connecting rod. The guide component is connected to the connecting rod. An axial guide structure is provided inside the housing, and the guide component is guided and engaged with the axial guide structure.

[0011] As an optional technical solution for corner protection devices, the axial guide structure is a straight groove formed on the inner wall of the housing.

[0012] As an optional technical solution for corner protection devices, the guide member has a guide protrusion, which slides in conjunction with the straight groove.

[0013] As an optional technical solution for corner protection device, two limiting bosses are provided inside the housing, and the two limiting bosses are distributed at intervals along the circumference of the connecting rod, with the guide protrusion located between the two limiting bosses.

[0014] As an optional technical solution for corner protection device, a circumferential guide structure is also provided inside the housing. The circumferential guide structure is distributed along the circumference of the connecting rod. The guide member can rotate under the guidance of the circumferential guide structure. The circumferential guide structure is an annular groove or arc-shaped groove opened on the inner wall of the housing.

[0015] As an optional technical solution for corner protection device, the axis of the output shaft of the driving component is set at an angle to the axis of the rotating component, and a transmission component is provided between the driving component and the rotating component.

[0016] As an optional technical solution for corner protection devices, the transmission assembly includes a worm and a worm wheel. The worm is fixedly connected to the output shaft of the drive component, and the worm wheel is fixedly sleeved on the rotating component. The worm and the worm wheel mesh with each other.

[0017] As an optional technical solution for corner protection devices, the protective head includes a U-shaped part and a sealing part. The U-shaped part has two side openings and one top opening. The connecting rod is connected to one side of the U-shaped part. The sealing part is closed and connected to one of the side openings of the U-shaped part away from the connecting rod. The U-shaped part and the sealing part together enclose and form the enclosing cavity.

[0018] As an optional technical solution for corner protection devices, the protective head is made of an elastic material.

[0019] A vehicle includes a body, a tailgate, and a corner protection device as described in any of the above embodiments. The body has a trunk, the tailgate is used to open and close the trunk, and the corner protection device is disposed on the inside of the tailgate. When the tailgate is opened, the drive assembly drives the protective head to wrap around the corner of the tailgate; when the tailgate is closed, the drive assembly drives the protective head to disengage from the corner of the tailgate and retract it into the inside of the tailgate.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a corner protection device, including a housing, a protective head, a connecting rod, and a drive assembly. The protective head is located outside the housing and has a covering cavity. The connecting rod is connected to the protective head. The drive assembly is located inside the housing and is drively connected to the connecting rod. The drive assembly is configured to drive the connecting rod to move axially and rotate about the axial direction. The corner protection device provided by this invention can be installed inside the tailgate of a vehicle. When the tailgate is open, the drive assembly first drives the connecting rod to move axially, and then drives the connecting rod to rotate about the axial direction. That is, the connecting rod first moves the protective head to the corner of the tailgate, and then drives the protective head to rotate so that the covering cavity covers the corner of the tailgate. Therefore, even if a user's head collides with the corner of the tailgate, the user will not be injured due to the protection of the protective head. When the tailgate is closed, the drive assembly first drives the connecting rod to rotate about the axial direction, and then drives the connecting rod to move axially. That is, the connecting rod first drives the protective head to rotate so that the covering cavity disengages from the corner of the tailgate, and then drives the protective head to move back, thus not affecting the closing of the tailgate. The corner protection device provided by this invention effectively solves the problem of head collisions at the corner of a vehicle's tailgate.

[0022] The present invention also provides a vehicle including the corner protection device provided by the present invention. By adopting the corner protection device, the user can be protected from injury without affecting the opening and closing of the tailgate, thus effectively solving the problem of head bumping at the tailgate corner.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figures 1 to 6 As shown, the present invention provides a corner protection device, including a housing 10, a protective head 20, a connecting rod 30, and a drive assembly. The protective head 20 is located outside the housing 10 and has a covering cavity 201. The connecting rod 30 is connected to the protective head 20. The drive assembly is located inside the housing 10 and is drively connected to the connecting rod 30. The drive assembly is configured to selectively drive the connecting rod 30 to move along the axial direction of the connecting rod 30 first and then rotate around the axial direction of the connecting rod 30, or to rotate around the axial direction of the connecting rod 30 first and then move along the axial direction of the connecting rod 30.

[0040] The corner protection device provided by this invention can be installed inside the tailgate 1 of a vehicle. When the tailgate 1 is opened, the drive assembly first drives the connecting rod 30 to move axially in the first translational direction, and then drives the connecting rod 30 to rotate axially in the first rotational direction. That is, the connecting rod 30 first drives the protective head 20 to translate to the corner position of the tailgate 1, and then drives the protective head 20 to rotate so that the wrapping cavity 201 wraps the corner of the tailgate 1. (Refer to...) Figure 5 Therefore, even if the user's head collides with the corner of the tailgate 1, the user will not be injured due to the protection of the protective head 20. When the tailgate 1 is closed, the drive assembly first drives the connecting rod 30 to rotate around the axial direction in the second rotational direction, and then drives the connecting rod 30 to move along the axial direction in the second translational direction. That is, the connecting rod 30 first drives the protective head 20 to rotate, causing the enclosure cavity 201 to disengage from the corner of the tailgate 1, and then drives the protective head 20 to translate and retract. Figure 6 This ensures that the closing of the tailgate 1 is not affected. The first translation direction is opposite to the second translation direction, and the first rotation direction is opposite to the second rotation direction, as shown in the reference. Figure 2 As shown by the arrow in the image.

[0041] Specifically, refer to Figure 1 and Figure 2 The protective head 20 includes a U-shaped portion 21 and a sealing portion 22. The U-shaped portion 21 has two side openings and one top opening. A connecting rod 30 is connected to one side of the U-shaped portion 21. The sealing portion 22 is closed and connected to one side opening of the U-shaped portion 21 opposite to the connecting rod 30. The U-shaped portion 21 and the sealing portion 22 together form a wrapping cavity 201. (Refer to...) Figure 5When the enclosure cavity 201 covers the corner of the tailgate 1, the U-shaped portion 21 covers the inner side 1a, outer side 1b, and bottom surface 1c of the tailgate 1, and the sealing portion 22 covers the left / right side 1d of the tailgate 1 (when the corner protection device protects the left corner of the tailgate 1, the sealing portion 22 covers the left side of the tailgate 1; when the corner protection device protects the right corner of the tailgate 1, the sealing portion 22 covers the right side 1d of the tailgate 1), thus providing all-around coverage of the corner. It should be noted that the inner side 1a, outer side 1b, bottom surface 1c, left side, and right side 1d of the tailgate 1 mentioned above are defined with the tailgate 1 in the closed state.

[0042] Preferably, the protective head 20 is made of an elastic material, such as a sponge, rubber, or latex, to provide better protection for the user when the user collides with the protective head 20. Preferably, all corners of the outer surface of the protective head 20 are rounded to further protect the user.

[0043] In this embodiment, refer to Figure 1 and Figure 3 The drive assembly includes a drive member 41, a transmission assembly 42, a rotating member 43, and a guide member 45. The drive member 41 can drive the rotating member 43 to rotate via the transmission assembly 42. A bearing 44 is provided between the rotating member 43 and the housing 10 to support the rotation of the rotating member 43. Optionally, two bearings 44 are provided, and the two bearings 44 are distributed at intervals along the axial direction of the rotating member 43. Optionally, the drive member 41 is a motor. In this embodiment, the axis of the output shaft of the drive member 41 is set at an angle to the axis of the rotating member 43, for example, the axis of the output shaft of the drive member 41 is perpendicular to the axis of the rotating member 43, thereby reducing the axial dimension of the overall structure. In this embodiment, the transmission assembly 42 includes a worm 421 and a worm wheel 422. The worm 421 is fixedly connected to the output shaft of the motor, and the worm wheel 422 is fixedly sleeved on the rotating member 43. The worm 421 and the worm wheel 422 mesh with each other. The power of the two intersecting shafts is transmitted through the worm wheel 422 and the worm 421, which is reliable and has low noise. Optionally, the worm gear 422 and the rotating component 43 are integrally formed. Alternatively, the transmission assembly 42 may also include two bevel gears, one of which is fixedly connected to the output shaft of the drive component 41, and the other bevel gear is fixedly connected to the rotating component 43, with the two bevel gears meshing. Alternatively, the drive component 41 may also directly drive the rotating component 43 to rotate.

[0044] Continue to refer to Figure 1 and Figure 3The rotating component 43 is coaxially arranged with the connecting rod 30. The rotating component 43 has an internal thread, and the connecting rod 30 has a threaded section 32. The rotating component 43 and the threaded section 32 of the connecting rod 30 are threadedly connected. The guide component 45 is fixedly connected to the connecting rod 30. Optionally, the connecting rod 30 also has a connecting section 33, which is located on the side of the threaded section 32 away from the protective head 20. Alternatively, the connecting section 33 can also be located on the side of the threaded section 32 facing the protective head 20, and the guide component 45 is fixedly sleeved on the connecting section 33. Optionally, the guide component 45 and the connecting section 33 can be interference-fitted or riveted. Optionally, the cross-section of the connecting section 33 is polygonal to prevent relative rotation between the guide component 45 and the connecting section 33, making the fixation of the guide component 45 more secure and reliable. Of course, the connection method between the guide component 45 and the connecting rod 30 is not limited to this. The guide component 45 can also be directly welded to the connecting rod 30, or the guide component 45 and the connecting rod 30 can be connected by fasteners, etc. An axial guide structure 121 is provided inside the housing 10, and the guide member 45 is guided and engaged with the axial guide structure 121.

[0045] Specifically, when the guide member 45 is engaged with the axial guide structure 121, the rotation of the connecting rod 30 is constrained. Therefore, the drive member 41 can only drive the connecting rod 30 to move axially via the rotating member 43. When the guide member 45 disengages from the axial guide structure 121, the rotational constraint on the connecting rod 30 is eliminated. Therefore, the drive member 41 can only drive the connecting rod 30 to rotate axially via the rotating member 43. The movement and rotation of the connecting rod 30 can be achieved simply by providing the axial guide structure 121 within the housing 10 to cooperate with the guide member 45. This design is simple and cost-effective.

[0046] In this embodiment, the axial guide structure 121 is a straight groove formed on the inner wall of the housing 10, and the guide member 45 has a guide protrusion 451, which slides in conjunction with the straight groove. Alternatively, the axial guide structure 121 can also be a straight boss formed on the inner wall of the housing 10, and the guide member 45 has a guide groove, which slides in conjunction with the straight boss.

[0047] Furthermore, referring to Figure 4 The housing 10 also includes a circumferential guide structure 122, which is distributed circumferentially along the connecting rod 30. The guide member 45 is guided and engaged with the circumferential guide structure 122, and can rotate under the guidance of the circumferential guide structure 122. The circumferential guide structure 122 is an annular groove or arc-shaped groove formed on the inner wall of the housing 10, and the guide protrusion 451 on the guide member 45 is located in the annular groove or arc-shaped groove.

[0048] Optionally, the guide member 45 includes a body and a pin disposed on the body. The body is annular and is fixedly sleeved on the connecting section 33 of the connecting rod 30. The body has a pin hole, and the pin is fixedly inserted into the pin hole. A portion of the pin protrudes from the body to form a guide protrusion 451. Alternatively, the guide member 45 can also be a pin directly, which is directly fixedly connected to the connecting rod 30. The connecting rod 30 has a pin hole, and the pin is fixedly inserted into the pin hole. A portion of the pin protrudes from the connecting rod 30 to form a guide protrusion 451.

[0049] Furthermore, continue to refer to Figure 4 The housing 10 contains two limiting bosses 123, which are spaced apart circumferentially along the connecting rod 30. A guide protrusion 451 is positioned between the two limiting bosses 123. By providing the two limiting bosses 123, the rotation angle of the connecting rod 30 can be limited, thus limiting the rotation angle of the protective head 20 and preventing excessive rotation. In this embodiment, the included angle between the two limiting bosses 123 is 180 degrees, meaning the rotation angle of the protective head 20 is 180 degrees, but this is not a limitation.

[0050] Alternatively, the drive assembly may include a telescopic drive and a rotary drive. The rotary drive is located at the output end of the telescopic drive and is connected to the connecting rod. The rotary drive drives the connecting rod to rotate about its axial direction, and the telescopic drive drives the rotary drive and the connecting rod to move together along the axial direction of the connecting rod. Optionally, the telescopic drive can be an electric cylinder or an electric actuator, and the rotary drive can be a motor.

[0051] In this embodiment, refer to Figure 1 The housing 10 includes a first housing 11 and a second housing 12. The first housing 11 includes two mating half-shells 111, which enclose a receiving space. The motor 41, transmission assembly 42, and rotating component 43 are all disposed within the receiving space formed by the two half-shells 111. The two half-shells 111 are detachably connected to facilitate the disassembly, assembly, and maintenance of the motor 41, transmission assembly 42, and rotating component 43. Figure 3 As shown, the second housing 12 is connected to the side of the first housing 11 facing away from the protective head 20 and is in communication with the first housing 11. An axial guide structure 121 and a circumferential guide structure 122 are disposed on the second housing 12. In this embodiment, the second housing 12 and the first housing 11 are detachably connected. Optionally, the second housing 12 and the first housing 11 are plug-in connected, but this is not a limitation. The second housing 12 and the first housing 11 can also be connected by screws or laser welding.

[0052] Furthermore, continue to refer to Figure 1 and combined Figure 2 and Figure 3As shown, the housing 10 also includes a third housing 13, which is connected to and communicates with the first housing 11 on the side facing the protective head 20. A connecting rod 30 passes through the third housing, and the threaded section 32 of the connecting rod 30 is located within the third housing 13, the first housing 11, and the second housing 12 to protect the threaded section 32, preventing impurities from accumulating thereand ensuring reliable fit between the connecting rod 30 and the rotating component 43. In this embodiment, the third housing 13 and the first housing 11 are detachably connected. Optionally, the third housing 13 and the first housing 11 are plugged in. Alternatively, the third housing 13 and the first housing 11 can be connected by screws or laser welding. Optionally, the connecting rod 30 also has an optical axis section 31, which is connected to the protective head 20. In this embodiment, the protective head 20 has a connecting hole, and the optical axis section 31 is plugged into the connecting hole. Of course, the connection method between the protective head 20 and the connecting rod 30 is not limited to this; they can also be connected by welding, snap-fitting, insert injection molding, or fasteners. Optionally, the connecting rod 30 can be a metal rod.

[0053] The present invention also provides a vehicle, including a vehicle body, a tailgate 1 and a corner protection device as described above. The vehicle body has a trunk, the tailgate 1 is used to open and close the trunk, and the corner protection device is disposed on the inner side of the tailgate 1. The housing 10 is connected to the inner side wall of the tailgate 1. When the tailgate 1 is opened, the drive assembly drives the protection head 20 to wrap around the corner of the tailgate 1. When the tailgate 1 is closed, the drive assembly drives the protection head 20 to disengage from the corner of the tailgate 1 and retract into the inner side of the tailgate 1.

[0054] By adopting the aforementioned corner protection device, users can be protected from injury without affecting the opening and closing of the tailgate 1, thus effectively solving the problem of head bumping at the corner of the tailgate 1.

[0055] In this embodiment, the vehicle is an automobile.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
