Description

Technical Field

[0001] The present invention relates to the technical field of automobile tools, and in particular to a vehicle and a luggage rack thereof. Background Art

[0002] With the continuous development of automobile industry technology, car luggage racks are widely used in many types of cars. Luggage racks can improve the overall structure of the car's appearance, meet the user's demand for diversified car appearance, and at the same time carry the car user's luggage and increase the storage space of the car.

[0003] At present, the car luggage rack is usually fixedly installed on the car roof, and can be used to place items after adding a transverse luggage rack. However, the existing roof luggage rack objectively has some problems or needs to be improved.

[0004] For example, since the luggage rack is disposed on the roof and is located at a relatively high position, it is rather laborious for the user to place items on the luggage rack, and overall the utilization rate of the luggage rack located on the roof is very low.

[0005] For example, when items are placed on the roof rack, it may block the view of the sunroof; when items are placed on the roof rack, the height dimension of the car will be increased, which may make some roads with height restrictions impassable.

[0006] For example, when a luggage rack is installed on the roof, the wind resistance has already increased to a certain extent. When the luggage rack is used to place items, the wind resistance will be further increased. Especially when the vehicle is traveling at high speed, the energy consumption of the vehicle will increase due to the significant increase in wind resistance.

[0007] Therefore, it is necessary to provide a vehicle and a luggage rack thereof to solve at least one of the above problems. Summary of the invention

[0008] In view of the defects existing in the prior art, a vehicle and a luggage rack thereof are provided in an embodiment of the present invention.

[0086] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0087] The present invention provides a vehicle and a luggage rack thereof, which can change the position and shape of the luggage rack while retaining the function of the original roof luggage rack, so that it can be switched to a rear luggage rack, thereby improving the diversity of the luggage rack's functions, convenience of use, safety, better energy saving, etc.

[0088] Please refer to Figures 1 to 14 In the embodiment of the present application, a luggage rack of a vehicle is provided, and the luggage rack of the vehicle may include: a guide member 13, the guide member 13 is fixed on the roof sheet metal 11 and is arranged along a first direction X; a luggage rack body 2, the luggage rack body 2 as a whole extends longitudinally along the first direction X, and can be slidably matched with the guide member 13, the luggage rack body 2 includes a front luggage rack 21, a rear luggage rack 22, and a bending structure 3 arranged between the front luggage rack 21 and the rear luggage rack 22; the luggage rack body 2 has a first position (such as Figure 1 As shown), and the front luggage rack 21 is located at the roof sheet metal 11 and the rear luggage rack 22 is located at the second position of the rear sheet metal 12 (as shown Figure 2 ,like Figure 3 and Figure 4 As shown); when the luggage rack body 2 switches from the first position to the second position, the luggage rack body 2 slides backward along the first direction X (i.e., the side of the rear sheet metal 12) relative to the guide member 13 to a predetermined position, the front luggage rack 21 stops sliding, and the rear luggage rack 22 bends downward at a predetermined angle relative to the front luggage rack 21 at the bending structure 3.

[0089] The luggage rack provided in the present application is based on the roof luggage rack, and a guide member 13 is provided so that the luggage rack body 2 can move backward or forward along the guide member 13. When the luggage rack moves backward, the rear luggage rack 22 is bent downward by the bending structure 3 until the rear end of the rear luggage rack 22 is attached to the rear sheet metal 12 and fixed, thus realizing the function of switching from the roof luggage rack to the rear storage rack, thereby improving the diversity of the luggage rack functions, the convenience of use, and the safety, and making the vehicle more energy-efficient when driving at high speed.

[0090] Taking placing a bicycle on the luggage rack as an example, after the roof luggage rack is switched to the rear rack, the user can easily place the bicycle on the rear rack because the rear rack is relatively low; the bicycle placed on the rear rack will not increase the height of the vehicle, and thus will not affect the vehicle's passability, and will not block the view of the sunroof; since the rear rack is located at the rear of the vehicle, the bicycle placed on the rear rack will have little effect on the wind resistance of the vehicle when driving at high speed, and will basically not increase the vehicle's energy consumption.

[0091] The present application will be described in detail below with reference to specific drawings and implementation methods.

[0092] In the embodiment of the present application, the luggage rack may mainly include: a guide member 13 and a luggage rack body 2 that can slide relative to each other.

[0093] The guide member 13 can be fixed on the roof sheet metal 11 and arranged along the first direction X. Specifically, the guide member 13 and the luggage rack body 2 can be in the form of a guide rail and a guide groove. Between the guide member 13 and the luggage rack body 2, one of them can be provided with a guide rail, and the other can be provided with a guide groove.

[0094] Please refer to Figure 1 , Figure 5 and Figure 6 In one embodiment, the guide member 13 can be a sliding guide rail, and the sliding guide rail has a first clamping portion 131. The luggage rack body 2 has a second clamping portion 201 that cooperates with the first clamping portion 131. The first clamping portion 131 and the second clamping portion 201 cooperate to form a clamping mechanism.

[0095] In this embodiment, the guide member 13 may be in the form of a sliding guide rail, which may be connected to the roof sheet metal 11 by a fixed connection. Overall, the sliding guide rail may be longitudinally extended along a first direction X. The first direction X is the front-rear direction of the vehicle.

[0096] Wherein, the sliding guide rail may include a first rail and a second rail arranged at a certain distance apart. The cross-sections of the first rail and the second rail may be symmetrically (or approximately symmetrically) arranged in an inverted L shape. Taking the first rail located on the left side of the figure as an example, the first rail may include a first side wall extending along a third direction Z (height direction) as a whole and a left end wall located at the top of the first side wall and extending outward in a direction away from the second rail. Correspondingly, taking the second rail located on the right side of the figure as an example, the second rail may include a second side wall extending along the height direction as a whole and a right end wall located at the top of the second side wall and extending outward in a direction away from the first rail. The left end wall and the right end wall are used to form the first clamping portion 131.

[0097] The luggage rack body 2 is provided with a second clamping portion 201 that is buckled on both sides of the first rail and the second rail near the bottom of the sliding guide rail. The second clamping portion 201 can be a structure that is formed downward and inward on the bottom surface of the luggage rack body 2 and is compatible with the first end wall and the second end wall, such as a group of L-shaped ribs that are buckled on the left end wall and the right end wall respectively. After the first clamping portion 131 and the second clamping portion 201 cooperate to form a clamping mechanism, the luggage rack body 2 can not only be guided by the sliding guide rail, but also limited, thereby ensuring that the luggage rack body 2 can be reliably installed on the vehicle body sheet metal.

[0098] Of course, the specific setting method of the card-connecting structure can also be other methods, and is not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0099] In the implementation manner of the present application, the luggage rack body 2 can extend longitudinally along the first direction X as a whole, and can be slidably matched with the guide member 13. Specifically, the power for the luggage rack body 2 to slide relative to the guide member 13 can include multiple forms, such as manual form, automatic form, or a combination of manual and automatic form. When the power is automatic, it can improve the convenience of use and improve the user experience. In the implementation manner of the present application, the electric form in the automatic form is used as an example for explanation.

[0100] In one embodiment, the luggage rack may further include a first driving mechanism 4, which is connected to the front luggage rack 21 and is used to drive the luggage rack body 2 to slide forward and backward along the first direction X relative to the guide member 13.

[0101] In this embodiment, the luggage rack body 2 can be driven by a first driving mechanism 4. Specifically, the power source of the first driving mechanism 4 can be electricity or other methods.

[0102] like Figure 6 As shown, specifically, the luggage rack body 2 may be a hollow structure with a cavity formed inside. Specifically, the luggage rack body 2 may be made of a profile, and the corresponding cavity formed inside may be a cavity structure. The first driving mechanism 4 is installed in the cavity, and the first driving mechanism 4 includes: a motor, a roller 41 and a fixed shaft 42. The motor is used to drive the roller 41 to rotate; when the roller 41 rolls along the guide member 13 driven by the motor, it drives the fixed shaft 42 to move along the guide member 13; the fixed shaft 42 is fixedly connected to the front luggage rack 21, and when the fixed shaft 42 moves along the guide member 13, it drives the luggage rack to move along the guide member 13.

[0103] In this embodiment, the luggage rack body 2 can be a hollow frame structure with a cavity arranged inside, and the first drive mechanism 4 can be installed in the cavity. Of course, the embodiment of the present application does not exclude the form of partially arranging the first drive mechanism 4 outside the cavity.

[0104] The first driving mechanism 4 may include: a motor as a power source, the motor may output torque, thereby driving the roller 41 to rotate. The motor may be arranged in the roller 41. When the motor is integrated in the roller 41, not only the transmission structure between the motor and the roller 41 can be reduced, but also the roller 41 can be used to protect the motor, thereby extending the service life of the motor.

[0105] The roller 41 may be cylindrical as a whole, and may be located on the upper surface of the guide member 13. Specifically, both ends of the roller 41 may be overlapped on the upper end surfaces of the first rail and the second rail, respectively.

[0106] The two ends of the fixed shaft 42 can be fixed on the front luggage rack 21, and the middle part can be fixedly connected with the roller 41 or form a relatively static torque transmission structure with the roller 41 in the circumferential direction, so as to convert the torque output by the roller 41 into the power to drive the luggage rack body 2 to move. Specifically, the fixed shaft 42 can be located at the center of the roller 41.

[0107] When the motor drives the roller 41 to rotate, the roller 41 rolls along the guide member 13 driven by the motor, thereby driving the fixed shaft 42 and the luggage rack body 2 connected to the fixed shaft 42 to move along the guide member 13 .

[0108] In the embodiment of the present application, the luggage rack body 2 may include a front luggage rack 21, a rear luggage rack 22, and a bending structure 3 disposed between the front luggage rack 21 and the rear luggage rack 22. The front luggage rack 21 and the rear luggage rack 22 may be bent at the bending structure 3.

[0109] The front luggage rack 21 can always be located on the roof sheet metal 11, so that it can always be constrained and limited by the guide member 13. The rear luggage rack 22 can be located behind the roof sheet metal 11 before sliding and folding, and can be located at the rear of the vehicle after sliding and folding, and can be fixed to the rear sheet metal 12, so as to cooperate with the front luggage rack 21 to form a rear luggage rack.

[0110] The power form of the bending structure 3 to achieve bending of the rear luggage rack 22 relative to the front luggage rack 21 at a predetermined angle may be manual, automatic, or a combination of manual and automatic.

[0111] For example, the bending structure 3 may include: a connector that is deformable as a whole, and the connector may be deformed according to the structure of the vehicle body sheet metal, so as to meet the requirement that the above-mentioned rear luggage rack 22 bends downward at a predetermined angle. Alternatively, the bending structure 3 may include a rotating shaft, and the rotating shaft is used as the rotation center to achieve the above-mentioned rear luggage rack 22 bending downward at a predetermined angle. Alternatively, the bending structure 3 may also be a combination of the above two, or it may also be other forms that can achieve the rear luggage rack 22 bending at a predetermined angle relative to the front luggage rack 21. Its specific form is not limited to the above description. Technicians in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the protection scope of this application.

[0112] like Figure 7 As shown in one embodiment, the bending structure 3 may include: a front axle 31, which is arranged on the side of the front luggage rack 21; a rear axle 32, which is arranged on the side of the rear luggage rack 22; a first rotating shaft 33, which is located between the front axle 31 and the rear axle 32, and is rotatably connected to both the front axle 31 and the rear axle 32; when the luggage rack body 2 is switched from the first position to the second position, the rear luggage rack 22 is bent downward by a predetermined angle relative to the front luggage rack 21 around the first rotating shaft 33.

[0113] In this embodiment, the bending structure 3 may include a rotating shaft. A front shaft 31 may be provided on the side of the front luggage rack 21, and a rear shaft 32 may be provided on the side of the rear luggage rack 22. The ends of the front shaft 31 and the rear shaft 32 that are close to each other are both rotatably connected to the first rotating shaft 33. When the luggage rack body 2 needs to be switched from the first position to the second position, the rear luggage rack 22 may be bent downward at a predetermined angle relative to the front luggage rack 21 around the first rotating shaft 33.

[0114] Among them, any one of the front axle 31 or the rear axle 32 can be fixed relative to the front luggage rack 21 or the rear luggage rack 22 (for example, fixedly connected, or integrally formed, etc.), or can be movable relative to the front luggage rack 21 or the rear luggage rack 22. For example, when the front axle 31 can move relative to the front luggage rack 21 along the first direction X, and the rear axle 32 is fixed relative to the rear luggage rack 22, when bending, the front axle 31 can first drive the first rotating shaft 33 to move a certain distance relative to the front luggage rack 21, so as to avoid interference between the front luggage rack 21 and the rear luggage rack 22 at the bent ends when bending.

[0115] Of course, in some other embodiments, the rear axle 32 can be moved relative to the rear luggage rack 22, and the front axle 31 is fixed relative to the front luggage rack 21. Relatively speaking, since the front luggage rack 21 is always located on the roof sheet metal 11 and is limited by the guide member 13, when the front axle 31 moves relative to the front luggage rack 21, the direction of its movement is controllable, which facilitates accurate switching between two different positions. In the embodiments of the present application, this case is mainly used as a typical embodiment for detailed description, and other cases can be adaptively referred to the present application.

[0116] like Figure 8 As shown, one end of the front luggage rack 21 close to the rear luggage rack 22 is a front docking end, and one end of the rear luggage rack 22 close to the front luggage rack 21 is a rear docking end. The bending structure 3 also includes a flexible seal 40, and the flexible seal 40 is connected between the front docking end and the rear docking end.

[0117] In this embodiment, the front luggage rack 21 has a front docking end connected to the rear luggage rack 22, and the rear luggage rack 22 has a rear docking end connected to the front luggage rack 21. In order to ensure the sealing of the front docking end and the rear docking end at the matching position, the bending structure 3 may include a flexible sealing member 40. The flexible sealing member 40 is provided between the front docking end and the rear docking end to achieve a sealing effect, thereby preventing water, particulate matter and impurities in the external environment from entering the luggage rack body 2 through the docking position of the front luggage rack 21 and the rear luggage rack 22; at the same time, the bending structure 3 at this position can be protected.

[0118] Specifically, the flexible seal 40 can be made of PVC flexible material with good waterproof performance, so as to better play the role of waterproofing and protecting the internal bending structure 3. When the flexible seal 40 is PVC flexible material, the PVC flexible material can be glued between the front docking end and the rear docking end. Of course, the material of the flexible seal 40 is not limited to the above examples, and it can also be other forms.

[0119] Please combine Figure 7 , Figure 8 , Fig. 9 and Fig.10 In one embodiment, the end of the front luggage rack 21 close to the rear luggage rack 22 is a front docking end, and a front baffle 38 is provided at the front docking end. The periphery of the front baffle 38 is connected to the front luggage rack 21, and the middle of the front baffle 38 is provided with a first opening 381 for passing the front axle 31 and the first rotating shaft 33.

[0120] In this embodiment, a front baffle 38 may be provided at the front docking end, the periphery of the front baffle 38 may be connected to the inner surface of the front luggage rack 21, and the middle portion of the front baffle 38 may be provided with a first opening 381 for passing the front axle 31 and the first rotating shaft 33, thereby providing support for the front axle 31, so that when it moves relatively, it can be suspended in the cavity of the front luggage rack 21 without contacting the inner surface of the front luggage rack 21, thereby ensuring the flexibility and reliability of sliding.

[0121] Specifically, the front shaft 31 as a whole may be in the shape of a rod extending longitudinally along the first direction X, and the shape of the first opening 381 may be adapted to the larger cross section of the front shaft 31 and the first rotating shaft 33. For example, when the cross section of the first rotating shaft 33 is larger, the cross section of the first opening 381 may be the same as or close to the cross section of the first rotating shaft 33.

[0122] Among them, the entire circumferential contour of the periphery of the front baffle plate 38 can be adapted to the cross-section of the front partial luggage rack 21 at the front docking end, and the periphery of the front baffle plate 38 can be sealed and connected to the inner surface of the luggage rack, thereby further improving the sealing and waterproof performance of the front partial luggage rack 21.

[0123] Please combine Figure 7 , Figure 8 , Fig. 9 and Fig.10 The end of the rear luggage rack 22 close to the front luggage rack 21 is a rear docking end, and a rear baffle 39 is provided at the rear docking end. The periphery of the rear baffle 39 is connected to the rear luggage rack 22, and the middle of the rear baffle 39 is provided with a second opening 391 for passing the rear axle 32.

[0124] In this embodiment, a rear baffle 39 may be provided at the rear docking end, and the periphery of the rear baffle 39 may be connected to the inner surface of the rear luggage rack 22, and the middle portion of the rear baffle 39 may be provided with a second opening 391 for passing the rear axle 32, thereby providing support for the rear axle 32, so that when it moves relatively, it can be suspended in the cavity of the rear luggage rack 22 without contacting the inner surface of the rear luggage rack 22, thereby ensuring the flexibility and reliability of rotation.

[0125] The entire circumferential contour of the rear baffle 39 can be matched with the cross section of the rear luggage rack 22 at the front docking end, and the periphery of the rear baffle 39 can be sealed and connected with the inner surface of the luggage rack, thereby further improving the sealing and waterproof performance of the rear luggage rack 22. The rear axle 32 is at least provided with a transition part, such as a sleeve, that is matched with the first rotating shaft 33. Of course, in this embodiment, since the rear axle 32 is fixed relative to the rear luggage rack 22, there are many ways for the rear axle 32 to be fixed on the rear luggage rack 22. Therefore, the specific shape and structure of the rear axle 32 are not specifically limited in this application.

[0126] For example, Figure 7 As shown, the rear axle 32 can be a longitudinally extending shaft section as a whole, one end of which can be fixed by the rear baffle 39, and the other end can be fixed by the rear plate 392. The rear plate 392 can be fixed in the rear luggage rack 22. Overall, the rear axle 32, the rear baffle 39 and the rear plate 392 can be a whole, which can be formed by an integral structure or fixed by assembly connection.

[0127] In a specific embodiment, a front baffle 38 is provided at the front docking end, and a rear baffle 39 is provided at the rear docking end. One of the front baffle 38 and the rear baffle 39 is provided with a protrusion with a gradually decreasing cross-section, and the other is provided with a groove with a gradually increasing cross-section. The protrusion and the groove cooperate to form a docking guide structure.

[0128] In this embodiment, in the case where a front baffle plate 38 is provided at the front docking end and a rear baffle plate 39 is provided at the rear docking end, the structures of the front baffle plate 38 and the rear baffle plate 39 are adaptively arranged so as to form a docking guide structure.

[0129] Please combine Figure 7 , Figure 8 , Fig. 9 and Fig.10 For example, a convex portion with a gradually reduced cross section is provided on the rear baffle 39, and the convex portion can be used to form an insertion head; a groove portion with a gradually increased cross section is provided on the front baffle 38, and the groove portion can be used to form an insertion cavity. When the rear luggage rack 22 needs to be switched from the second position to the first position with the front luggage rack 21, the docking guide structure formed by the cooperation of the two can enable the rear luggage rack 22 to accurately dock and reset with the front luggage rack 21.

[0130] In some embodiments, the bending structure 3 can be used to realize that the power form of the rear luggage rack 22 bending a predetermined angle relative to the front luggage rack 21 is an automatic form, which can improve the convenience of use and improve the user experience. In the embodiments of this application, the electric form in the automatic form is used as an example for explanation.

[0131] In some embodiments, the bending structure 3 may further include: a second driving mechanism 34, the second driving mechanism 34 is used to drive the front axle 31 to move along the first direction X and / or to drive the rear luggage rack 22 to bend downward at a predetermined angle relative to the front luggage rack 21.

[0132] In this embodiment, the second driving mechanism 34 can provide driving force for the movement of the front axle 31 and / or the second driving mechanism 34 can provide driving force for the rear luggage rack 22 to bend relative to the front luggage rack 21. In the embodiment of the present application, the second driving mechanism 34 provides driving force for the movement of the front axle 31 and provides driving force for the bending of the rear luggage rack 22 as an example for illustration.

[0133] Specifically, the second driving mechanism 34 may be in the form of a motor. Of course, the specific form of the second driving mechanism 34 may also be other, and the present application does not make any specific limitation here.

[0134] For the form in which the second driving mechanism 34 is provided, taking a motor as an example, the motor can be located in the cavity of the front luggage rack, so that the motor is protected by the front luggage rack 21. The motor can be fixed to the front axle 31, so as to provide the front axle 31 with a driving force to drive the front axle 31 to move along the first direction X.

[0135] When the luggage rack body 2 needs to be switched from the first position to the second position, the second drive mechanism 34 can be started after the front luggage rack 21 reaches a predetermined position, that is, a designated stop position. The stop position of the front luggage rack 21 can be close to the rear sheet metal 12. Specifically, it can be achieved by setting a matching limit mechanism between the end of the guide member 13 and the front luggage rack 21. For example, when the front luggage rack 21 reaches the end of the guide member 13, the two cooperate to form a limit mechanism, that is, the designated stop position is reached; and / or, the travel of the front luggage rack 21 is monitored by the first drive mechanism 4. For example, when the first drive mechanism 4 detects that the moving distance of the front luggage rack 21 reaches the set travel, the front luggage rack 21 can be stopped from being driven, so that it stays at the designated stop position; of course, the form of controlling the stop position of the front luggage rack 21 to be the designated stop position can also be other ways, and the present application does not make specific limitations here.

[0136] In order to allow the rear luggage rack 22 to be smoothly bent relative to the front luggage rack 21, the second driving mechanism 34 can be used to provide a driving force so that the front axle 31 pushes the rear luggage rack 22 to separate from the front luggage rack 21 first and then bends them.

[0137] Specifically, after the front luggage rack 21 stops at a designated stop position under the action of the first driving mechanism 4, the second driving mechanism 34 can be used to drive the front axle 31 to continue to move relative to the front luggage rack 21, so that a bending spacing distance is formed between the rear luggage rack 22 and the front luggage rack 21, thereby forming the space required for the front luggage rack 21 and the rear luggage rack 22 to bend.

[0138] Furthermore, the bending structure 3 may also include: a limiting structure, which is arranged at the end of the front luggage rack 21 close to the rear luggage rack 22 and is located at the lower side of the front luggage rack 21 along the height direction; a limiting slide 35, which is slidably matched with the limiting structure, and the limiting slide 35 is connected to the front axle 31, and can be driven by the front axle 31 to slide along the first direction X; a second rotating shaft 36, which is arranged at one end of the limiting slide 35 close to the rear luggage rack 22, and the second rotating shaft 36 is rotatably connected to one end of the rear luggage rack 22 close to the front luggage rack 21.

[0139] When the luggage rack body 2 switches from the first position to the second position, after the front luggage rack 21 stops sliding, the second driving mechanism 34 drives the front axle 31 to move relative to the front luggage rack 21 and drives the limiting slide 35 to move; when the limiting slide 35 is constrained by the limiting structure and stops moving, the front axle 31 continues to move a predetermined distance, and the rear luggage rack 22 bends downward at a predetermined angle relative to the front luggage rack 21 around the first rotating shaft 33 and the second rotating shaft 36.

[0140] See also Fig.11 and Fig.12 Specifically, the limiting structure may include a limiting groove 37 arranged on the front luggage rack 21 and extending along the first direction X, the limiting groove 37 has a relative starting end 371 and an ending end 372 in the first direction X, the limiting slide plate 35 includes a plate-like body, and the side edge of the plate-like body is provided with a limiting portion 351 that cooperates with the limiting groove 37, and the limiting portion 351 moves between the starting end 371 and the ending end 372.

[0141] In this embodiment, a mounting bottom groove 210 may be provided on the lower side wall surface of the front luggage rack 21 near the front docking end, and a limiting groove 37 is provided on at least one side of the mounting bottom groove 210 in the second direction Y perpendicular to the first direction X. In this embodiment, two limiting grooves 37 are provided as an example, namely a left limiting groove and a right limiting groove, and the left limiting groove and the right limiting groove are arranged opposite to each other. Along the first direction X, the limiting groove 37 has a starting end 371 and a terminating end 372. The starting end 371 is an end close to the second driving mechanism 34, and the terminating end 372 is an end away from the second driving mechanism 34. The terminating end 372 has a certain stopping distance from the front docking end. The stopping distance can firstly ensure that the end of the limiting slide 35 provided with the second rotating shaft 36 can extend out of the front part of the luggage rack 21. At the same time, the stopping distance can ensure that the limiting slide 35 is subjected to uniform force, especially reducing the relative force between the limiting part 351 and the limiting groove 37, thereby extending the service life of the limiting slide 35.

[0142] The movable distance of the limiting slide plate 35 in the first direction X is S1, and the wall thickness of the lower side of the rear luggage rack 22 close to the body sheet metal is S2, and S1 is greater than or equal to S2. The movable length S1 of the limiting slide plate 35 needs to be greater than the wall thickness S2 of the bottom of the rear luggage rack 22, and the rear luggage rack 22 can retreat backwards to a sufficient space to ensure that when the rear luggage rack 22 is folded downward, the bottom of the rear luggage rack 22 will not interfere with the bottom of the front luggage rack.

[0143] On the whole, through the cooperation of the limiting slide plate 35 and the limiting structure, it is equivalent to adding a first-level anti-interference structure on the basis of the original structure in which the front axle 31 moves relative to the front luggage rack 21, which can improve the stability and reliability of the front luggage rack 21 and the rear luggage rack 22 when bending, and effectively avoid the interference between the two at the bottom of the rear luggage rack 22 and the bottom of the front luggage rack when bending; at the same time, it cooperates with the above-mentioned front axle 31, the first rotating shaft 33 and the rear axle 32, and can also realize the automatic bending of the rear luggage rack 22 relative to the front luggage rack 21 under the drive of the second driving mechanism 34, so that the rear luggage rack 22 bends downward at a predetermined angle until it contacts the rear sheet metal 12.

[0144] In a specific embodiment of the present application, the bending structure 3 may include: a second driving mechanism 34, the second driving mechanism 34 is used to drive the front axle 31 to move along the first direction X; a limiting structure, the limiting structure is arranged at the end of the front luggage rack 21 close to the rear luggage rack 22 and is located at the lower side of the front luggage rack 21 along the height direction; a limiting slide 35, the limiting slide 35 cooperates with the limiting structure, and the limiting slide 35 is connected to the front axle 31, and can be driven by the front axle 31 to slide along the first direction X; a second rotating shaft 36, the second rotating shaft 36 is arranged at one end of the limiting slide 35 close to the rear luggage rack 22, and the second rotating shaft 36 is rotatably connected to one end of the rear luggage rack 22 close to the front luggage rack 21. When the luggage rack body 2 switches from the first position to the second position, after the front luggage rack 21 stops sliding, the second driving mechanism 34 drives the front axle 31 to move relative to the front luggage rack 21 and drives the limiting slide 35 to move; when the limiting slide 35 is constrained by the limiting structure and stops moving, the front axle 31 continues to move a predetermined distance, and the rear luggage rack 22 bends downward at a predetermined angle relative to the front luggage rack 21 around the first rotating shaft 33 and the second rotating shaft 36.

[0145] In this embodiment, the bending structure 3 including: the first driving mechanism 4, the front axle 31, the rear axle 32, the first rotating shaft 33, the second driving mechanism 34, the limiting structure, the limiting slide plate 35 and the second rotating shaft 36 is taken as an example for detailed description.

[0146] The specific structures, connection relationships and functions of the first driving mechanism 4, the front axle 31, the rear axle 32, the first rotating shaft 33 and the second driving mechanism 34 can refer to the specific description of the above embodiments, and the same points will not be described in detail in this application. The first rotating shaft 33 is located in the middle of the luggage rack body 2, and serves as the main rotating shaft of the bending structure 3. The second rotating shaft 36 is located on the lower side of the first rotating shaft 33 and also on the lower side of the luggage rack body 2 (for example, on the bottom wall of the front part of the luggage rack 21), and can serve as the secondary rotating shaft of the bending structure 3.

[0147] The luggage rack provided in the embodiment of the present application, when it is necessary to switch from the first position to the second position, can first use the first driving mechanism 4 to drive the entire luggage rack body 2 to move to the rear of the vehicle body sheet metal; after reaching the predetermined position; the first driving structure stops driving; and the second driving mechanism 34 is started. Under the action of the second driving mechanism 34, the front axle 31 and the limiting slide 35 move to the rear of the vehicle body sheet metal at the same time, and the rear luggage rack 22 moves backward along the first direction X (horizontal direction), providing space for the rear luggage rack 22 to fold downward, so as to avoid the rear luggage rack 22 from interfering with the front luggage rack 21 when folding downward. The limiting slide 35 is provided with a limiting structure, which can be located at one end of the limiting slide 35 away from the second rotating shaft 36 or at a position half the length of the limiting slide 35. Of course, the limiting structure can also be located at other positions. In the embodiment of the present application, the limiting structure is located at a position half the length of the limiting slide 35 as an example for illustration.

[0148] When the limiting slide plate 35 moves back halfway, the limiting slide plate 35 is limited by the limiting structure, and the two remain relatively still. At this time, the secondary shaft can only rotate along the axis, and the front shaft 31 continues to move backward. Under the driving action of the second driving mechanism 34, and under the rotation cooperation of the main shaft and the secondary shaft, the rear luggage rack 22 slowly folds downward until the rear luggage rack 22 reaches the specified folding position, and the second driving mechanism 34 stops working. At this time, the rear luggage rack 22 is folded into place.

[0149] In some embodiments, the luggage rack may further include a connecting component connected between the luggage rack body 2 and the vehicle body sheet metal. When the rear luggage rack 22 is bent downward at a predetermined angle relative to the front luggage rack 21 at the bending structure 3, the luggage rack body 2 is fixed to the vehicle body sheet metal through the connecting component.

[0150] The number of the connecting components may be one or more, and the number of the connecting components may vary according to the length of the luggage rack body 2 (the front luggage rack 21 and the rear luggage rack 22), the setting position of the connecting components, the connection strength of the connecting components, etc.

[0151] For example, in order to ensure that the luggage rack has a better load-bearing capacity, the connection components between the luggage rack and the body sheet metal can be set as two groups between the front luggage rack 21 and the roof sheet metal 11, such as Figure 3 As shown, they are respectively at position P1 and position P2; two groups are set between the rear luggage rack 22 and the rear sheet metal 12, such as Figure 4As shown, they are position P3 and position P4 respectively. Position P1 and position P2 are set at the front and rear ends of the front luggage rack 21, position P1 is close to the front end of the front luggage rack 21, position P2 is close to the rear end of the front luggage rack 21, and close to the rear end of the roof sheet metal 11. Position P3 and position P4 are set at the rear end of the rear luggage rack 22, position P3 is set near the upper part of the rear sheet metal 12, and position P4 is set at the rear end of the rear luggage rack 22.

[0152] The connection form of the connection component may include various forms. Specifically, the connection component may include a manual quick-connect structure or an automatic quick-connect structure.

[0153] Among them, in order to improve the overall convenience of the luggage rack and enhance the user experience, the connecting component can be an automatic quick-connect structure.

[0154] like Fig.13 or Fig.14 As shown, in one embodiment, the connection assembly can be an automatic quick-connect structure. The connection assembly includes: a telescopic support assembly, which can be telescopically moved in a direction away from the vehicle body sheet metal or close to the vehicle body sheet metal after being driven; a limit switch assembly, which is arranged in the luggage rack body 2 and is used to cooperate with the telescopic support assembly to form a locked state and an unlocked state. In the locked state, the telescopic support assembly applies a restraining force to the luggage rack body 2 through the limit switch assembly.

[0155] In this embodiment, the connection assembly may include a telescopic support assembly and a limit switch assembly. When the rear luggage rack 22 is bent at a predetermined angle relative to the front luggage rack 21 and contacts the rear sheet metal 12, the power mechanism in the vehicle can drive the telescopic support assembly to move away from the body sheet metal, and the telescopic support assembly cooperates with the limit switch assembly to form a locked state, thereby applying a restraining force to the luggage rack body 2, realizing the automatic connection function between the luggage rack body 2 and the body panel, and at the same time ensuring that the luggage rack has sufficient load-bearing capacity.

[0156] Specifically, the telescopic support assembly may include: a support member 5, the support member 5 having a lower end extending into the vehicle body sheet metal and an upper end extending out of the vehicle body sheet metal, the upper end being provided with an upper conical structure 50, the cross-section of the upper conical structure 50 gradually increasing from top to bottom; a lower conical structure 6, the lower conical structure 6 being movably mounted on the support member 5 and located on the inner side of the upper conical structure 50, the cross-section of the lower conical structure 6 gradually decreasing from top to bottom.

[0157] The limit switching assembly may include: a limit base 7, which is fixed on the luggage rack body 2 and is provided with a center hole 70 along the telescopic direction of the support member 5, and is provided with a plurality of movement cavities 71 perpendicular to the telescopic direction; a latch member 8, which is inserted into the movement cavity 71, with one end of the latch member 8 resting against the outer side surface of the limit base 7, and the other end being able to extend out of the movement cavity 71 to cooperate with the upper conical structure 50 or the lower conical structure 6; a return member 9, which is located in the movement cavity 71 and can provide a return force for the latch member 8.

[0158] When the connecting assembly switches from the unlocked state to the locked state, the support member 5 extends into the center hole 70, and the latch member 8 moves from the inside to the outside in the movement cavity 71 under the action of the upper conical structure 50. When the latch member 8 reaches the bottom of the upper conical structure 50, the latch member 8 is reset under the action of the return member 9 and is located between the upper conical structure 50 and the lower conical structure 6.

[0159] In this embodiment, the limit switch assembly can be installed inside the luggage rack. Specifically, the limit switch assembly can be set inside the cavity of the luggage rack and fixed to the bottom bearing surface of the luggage rack. The limit switch assembly can include a limit base 7, a latch member 8 and a return member 9.

[0160] Among them, the limiting base 7 can be roughly in the form of a nut. Of course, the specific structure of the limiting base 7 can also be in other forms. In the embodiment of the present application, the limiting base 7 is illustrated as a nut-like structure. The limiting base 7 has a center hole 70 along the axial direction, that is, along the telescopic direction of the support member 5, so as to provide a movement space for the telescopic support assembly. Among them, the center hole 70 can be a through hole or a blind hole with a closed upper end. A plurality of motion cavities 71 are evenly spaced in the circumferential direction of the limiting base 7, so as to provide space for the movement of the latch. Specifically, the number of the motion cavities 71 can be 2, and the two motion cavities 71 are symmetrically distributed at an interval of 180° in the circumferential direction. Of course, the number of the motion cavities 71 can also be more, and the present application does not make a unique numerical limitation here. The specific structure of the motion cavity 71 may include a first hole segment with a first aperture, and the two ends of the first hole segment are respectively provided with a second hole segment with a smaller aperture close to the center and a third hole segment far from the center.

[0161] The restoring member 9 is disposed in the movement cavity 71. Specifically, the restoring member 9 may be in the form of a spring. Of course, the restoring member 9 may also be in other forms, which are not specifically limited in the present application. The restoring member 9 is disposed in the first hole section in the middle.

[0162] The latch member 8 is inserted into the movement cavity 71, one end of the latch member 8 abuts against the outer side surface of the limiting base 7, and the other end can extend out of the movement cavity 71 to cooperate with the upper conical structure 50 or the lower conical structure 6. The end of the latch member 8 abutting against the outer side surface of the limiting base 7 is the outer end, which can be in the form of a nut, the outer diameter of which is larger than the aperture of the third hole segment, so that the latch member 8 can be limited, so that when the latch member 8 moves inward under the action of the return member 9, its limit position is that the nut contacts the outer side wall of the limiting base 7. The middle part of the latch member 8 can be a rod segment, the diameter of which can be close to the diameter of the third hole segment, for example, it can be slightly smaller than the aperture of the third hole segment. The inner side of the latch member 8 closest to the center can be a rod section whose diameter matches the first hole section, and the head of the latch member 8 (i.e., the mating end of the latch member 8 and the upper conical structure 50 or the lower conical structure 6) can be in a sloped structure to ensure that the telescopic support assembly can retract downward.

[0163] The telescopic support assembly is arranged on the body sheet metal, and can be driven by the cylinder inside the body sheet metal to perform upward and downward telescopic movement. The telescopic support assembly can include: a support member 5, an upper conical structure 50 and a lower conical structure 6.

[0164] The support member 5 has a lower end extending into the body sheet metal and an upper end extending out of the body sheet metal, and the upper end is provided with an upper conical structure 50. The cross section of the upper conical structure 50 gradually increases from top to bottom.

[0165] The support member 5 may include a rod-shaped support body, which includes a first rod body 51 and a second rod body 52. ​​The diameter of the first rod body 51 is smaller than the diameter of the second rod body 52. ​​A limiting step 512 for limiting the lower conical structure 6 is formed at the junction of the first rod body 51 and the second rod body 52. ​​The lower conical structure 6 is movably mounted outside the first rod body 51.

[0166] The lower conical structure 6 is movably mounted on the support member 5 and is located inside the upper conical structure 50. The cross section of the lower conical structure 6 gradually decreases from top to bottom. The support member 5 and the upper conical structure 50 are a whole and are relatively stationary. The lower conical structure 6 can move up and down on the first rod 51, that is, between the second rod 52 and the upper conical structure 50.

[0167] Please combine Figure 3 and Fig.13As shown, when the luggage rack body 2 of the vehicle is moved and folded into place, when the connection assembly needs to be switched from the unlocked state to the locked state, the telescopic support assembly is inserted into the cavity of the luggage rack, and the latch member 8 moves radially outward under the action of the upper conical structure 50. When it reaches the bottom of the upper conical structure 50, the latch member 8 rebounds inward due to the action of the return member 9. Thereafter, the telescopic support assembly provides a downward pulling force under the action of the cylinder, and the pulling force is sequentially transmitted from the bottom of the upper conical structure 50 to the limiting base 7, the luggage rack, and then to the guide member 13 and the body sheet metal. The carrying capacity of the luggage rack is guaranteed by the pulling force between the guide member 13 and the luggage rack.

[0168] Please combine Figure 4 and Fig.14 As shown, for the rear panel 12, the difference from the above embodiment is that no guide member 13 is provided on the rear panel 12. During the transmission process, the pulling force is sequentially transmitted from the bottom of the upper conical structure 50 to the limiting base 7, the luggage rack, and then to the vehicle body panel.

[0169] like Fig.13 As shown, when the luggage rack body 2 needs to be switched from the second position to the first position, the connecting component needs to be switched from the locked state to the unlocked state. When the connecting component is switched from the locked state to the unlocked state, the movement of the telescopic support assembly can be divided into two parts.

[0170] Part 1: The telescopic support assembly first moves upward, the lower conical structure 6 contacts the latch member 8, and after the lower conical structure 6 contacts the latch member 8, it can move radially outward under the action of the lower conical structure 6. In order to ensure that the latch member 8 can move outward with the upward movement of the lower conical structure 6, in the telescopic direction of the support member 5, before the latch member 8 contacts the lower conical structure 6, the inclined surface of the latch member 8 can cover the maximum outer contour of the lower conical structure 6 when projected onto the lower conical structure 6.

[0171] Part 2: The telescopic support assembly moves downward. Since the lower conical structure 6 can perform telescopic movement up and down on the first rod body 51 with a smaller diameter, and the latch member 8 is subjected to an inward force due to the action of the return member 9, the lower conical structure 6 will move upward, opposite to the movement direction of the support member 5, until the upper end face of the lower conical structure 6 contacts the lower end face of the upper conical structure 50.

[0172] like Fig.15As shown, taking the upper conical structure 50 as a whole being a truncated cone as an example, the diameter of the lower end surface of the upper conical structure 50 is D1; ​​taking the lower conical structure 6 as a whole being a truncated cone as an example, the diameter of the upper end surface of the lower conical structure 6 is D2. Among them, the diameter D1 of the lower end surface of the upper conical structure 50 is equal to the diameter D2 of the upper end surface of the lower conical structure 6. At this time, as the telescopic support assembly continues to move downward, the latch member 8 will continue to slide onto the upper conical structure 50 until it finally stops contacting the telescopic support assembly. At this time, the luggage rack is disassembled. The telescopic support assembly continues to retract into the roof sheet metal 11.

[0173] To ensure that the telescopic support assembly structure can smoothly perform telescopic movement, the diameter D4 of the mounting hole provided on the vehicle body sheet metal and the diameter D3 of the opening provided on the luggage rack are both larger than the maximum diameter D1 / D2 of the telescopic rod assembly.

[0174] like Fig.16 As shown, the upward movement stroke of the telescopic support assembly is L1, the length of the first rod body 51 is L2, and when it abuts against the limiting step 512, the distance between the upper conical structure 50 and the lower conical structure 6 is L3, wherein L3<L1<L2.

[0175] In this embodiment, L1 is the upward movement stroke of the telescopic support assembly, L2 is the length of the thinner first rod 51, and L3 is the distance between the lower cone structure 6 and the upper cone structure 50 when the lower cone structure 6 is in a self-hanging state (i.e., when it abuts against the limit step 512). To ensure normal operation during disassembly, in the first part of the movement stroke of the telescopic support assembly, it is necessary to ensure that L3<L1<L2. Among them, L3<L1 can ensure that the latch member 8 can move to contact the lower cone structure 6. L1<L2 can ensure that the latch member 8 does not contact the second rod 52 with a larger diameter.

[0176] A vehicle is also provided in an embodiment of the present application, and the vehicle includes the above-mentioned luggage rack. The vehicle can achieve the technical effect achieved by the luggage rack embodiment by setting up the luggage rack. For details, please refer to the specific description of the above-mentioned embodiment, and the present application will not repeat them here.

[0177] In one embodiment, the vehicle body sheet metal includes a roof sheet metal 11 and a rear sheet metal 12, and multiple groups of connecting components are arranged between the luggage rack body 2 and the vehicle body sheet metal; a first mounting hole 111 for installing the connecting component is arranged on the roof sheet metal 11, and the first mounting hole 111 is located in the middle of the guide member 13; a second mounting hole 121 for installing the connecting component is arranged on the rear panel, and the luggage rack also includes a hollow supporting component 10 arranged on the rear sheet metal 12, and the supporting component 10 is arranged outside the second mounting hole 121.

[0178] For the embodiment in which the first mounting hole 111 is provided on the roof sheet metal 11, and the first mounting hole 111 is provided with a connecting component, it can be combined with reference to Figure 3 and Fig.13 , and the detailed description of the above-mentioned luggage rack implementation method will not be repeated in this application.

[0179] For the embodiment in which the second mounting hole 121 is provided on the rear sheet metal 12 and the second mounting hole 121 is provided with a connecting component, it can be combined with reference to Figure 4 and Fig.14 , and the specific description of the above luggage rack implementation method, the present application will not repeat them here. As for the support component 10, it can be fixedly connected to the periphery of the second mounting hole 121. Specifically, the support component 10 can be specifically annular, and the inner diameter of the support component 10 can be larger than the aperture of the second mounting hole 121, so as not to interfere with the support member 5. The outer diameter of the support component 10 can be smaller than the spacing between the two second clamping portions 201 of the rear luggage rack 22, so that one end of the support component 10 can extend between the two second clamping portions 201, thereby contacting the outer bottom wall of the rear luggage rack 22.
