Description

Technical Field

[0001] This utility model relates to the field of automotive interior structure technology, specifically to a novel luggage compartment flip panel mounting structure. Background Technology

[0002] In the field of automotive interior design, the gap between the trunk and the rear seat has long been a problem. When the rear seat angle is adjusted, the size of this gap dynamically changes, directly affecting the overall aesthetics of the interior. Existing solutions typically use a flip-up panel assembly linked to the seat angle to cover the gap. Its structure includes: mounting brackets located at the flip-up panel's fixing and flipping parts, and torsion springs at both ends that are respectively engaged with the mounting bracket's slots. However, this structure still has the following drawbacks in use:

[0003] 1. Dynamic abnormal noise problem: Because the existing torsion spring is connected to the mounting bracket by a slot, when the torsion spring is in contact with the mounting bracket, there will be a gap between it and the flip plate body, which will cause the torsion spring to shake during the flipping process and thus produce abnormal noise. At the same time, based on the existing installation method of the torsion spring, it will crush the spring limiting ribs on the mounting bracket and the flip plate during the flipping process, which will increase the gap between the flip plate body and the mounting bracket limiting spring, making it very easy for the spring to knock up and down during the flipping process, thus further aggravating the abnormal noise problem.

[0004] 2. Assembly process defects: Due to the size limitations of the mounting bracket, there are often problems such as small pressing space and pain in the hand when pressing the torsion spring into the slot during the process of pressing it.

[0005] Therefore, there is an urgent need for a new type of luggage flip panel installation structure. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a novel luggage flip panel installation structure.

[0007] This utility model discloses a novel luggage flip panel mounting structure, including:

[0008] A flip-up cover plate, comprising a fixed part and a rotating part rotatably connected by a number of rotating components;

[0009] A rotating component includes a first mounting bracket, a second mounting bracket, and a torsion spring. The first mounting bracket and the second mounting bracket are respectively mounted on a fixed part and a rotating part. The torsion spring connects the first mounting bracket and the second mounting bracket. Both the first mounting bracket and the second mounting bracket are provided with through holes for the two ends of the torsion spring to pass through and connect with shafts. The first mounting bracket and the second mounting bracket are respectively provided with a first Y-direction limiting part and a second Y-direction limiting part to limit the Y-direction displacement of the torsion spring.

[0010] The fixing part and the rotating part are respectively provided with Z-direction mounting parts corresponding to the first mounting bracket and the second mounting bracket. The first mounting bracket and the second mounting bracket are both provided with Z-direction limiting plane mating surfaces that cooperate with the Z-direction mounting parts.

[0011] As a further improvement of this utility model, first screw mounting portions are respectively provided on both sides of the Z-direction mounting portion on the fixing portion and the rotating portion;

[0012] Both ends of the first mounting bracket and both ends of the second mounting bracket are respectively provided with second screw mounting parts that cooperate with the first screw mounting part. After the screw passes through the second screw mounting part, it is screwed onto the first screw mounting part.

[0013] As a further improvement of this utility model, the first screw mounting part is a BOSS post, and the second screw mounting part is a positioning countersunk hole that mates with the BOSS post.

[0014] As a further improvement of this utility model, the torsion spring includes a winding part and a first mounting bracket through-shaft hole matching shaft and a second mounting bracket through-shaft hole matching shaft extending outward from both ends of the winding part. The end of the first mounting bracket through-shaft hole matching shaft near the winding part forms a Y-direction limiting point matching shaft, and the end face of the second mounting bracket through-shaft hole matching shaft forms a Y-direction limiting rib matching surface.

[0015] The first mounting bracket through-shaft hole matching shaft and the second mounting bracket through-shaft hole matching shaft are respectively inserted into the through-shaft holes on the first mounting bracket and the second mounting bracket; the Y-direction limiting point matching shaft and the Y-direction limiting rib matching surface are respectively engaged with the first Y-direction limiting part and the second Y-direction limiting part.

[0016] As a further improvement of this utility model, the first Y-direction limiting part includes a first mounting bracket spring Y-direction limiting point, and the Y-direction limiting point is matched with a shaft that is engaged within the first mounting bracket spring Y-direction limiting point; the second Y-direction limiting part includes a second mounting bracket spring Y-direction limiting rib, and the matching surface of the Y-direction limiting rib abuts against the second mounting bracket spring Y-direction limiting rib.

[0017] As a further improvement of this utility model, the first mounting bracket spring Y-direction limiting point is integrally formed with the first mounting bracket; the second mounting bracket spring Y-direction limiting rib is integrally formed with the second mounting bracket.

[0018] As a further improvement of this utility model, one end of the Z-direction mounting part of the fixing part is further provided with a spring limiting part, which is used to fit against the Y-direction limiting locking point matching shaft.

[0019] As a further improvement of this utility model, the number of rotating components is three, and the three rotating components are evenly spaced apart.

[0020] As a further improvement of this utility model, when the first mounting bracket and the fixing part are assembled in place, the Z-direction mounting part on the fixing part is in contact with the Z-direction limiting plane mating surface of the first mounting bracket.

[0021] When the second mounting bracket is assembled with the rotating part, the Z-direction mounting part on the rotating part is in contact with the Z-direction limiting plane mating surface of the second mounting bracket.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model features a simple structure and convenient assembly. By changing the fixing mode of the torsion spring, the traditional slot-type pressing assembly is modified to a through-shaft hole type through-shaft installation. With the first and second Y-axis limiting parts located on the first and second mounting brackets, the two ends of the torsion spring are firmly fixed in the first and second mounting brackets, thereby reducing the shaking of the torsion spring during the flipping process and reducing the possibility of abnormal noise caused by shaking. At the same time, it effectively solves the problems of limited pressing space and hand pain during the assembly process of the torsion spring. It also saves assembly time for individual units, shortens the cycle time, and effectively improves the company's overall profits, enhances user experience, and increases customer satisfaction.

[0024] This invention modifies the fixing method of the torsion spring, concentrating the force of the torsion spring onto the mounting bracket. This effectively prevents the torsion spring from crushing the spring limiting ribs on the mounting bracket and the flip cover, thereby avoiding the problem of increased gap between the flip cover and the mounting bracket limiting spring due to crushing of the spring limiting ribs, as well as the problem of increased abnormal noise from the spring being struck up and down.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings:

[0048] like Figure 1-3 As shown, a novel luggage flip panel mounting structure according to this utility model includes a flip cover plate 1 and a rotating component 2. The flip cover plate 1 includes a fixed part 11 and a rotating part 12 rotatably connected by several rotating components 2. The rotating component 2 includes a first mounting bracket 21, a second mounting bracket 22, and a torsion spring 23. The first mounting bracket 21 and the second mounting bracket 22 are respectively mounted on the fixed part 11 and the rotating part 12. The torsion spring 23 connects the first mounting bracket 21 and the second mounting bracket 22. The first mounting bracket 21 and the second mounting bracket 22 are each provided with a through-shaft hole for the two ends of the torsion spring 23 to be connected by a shaft. The first mounting bracket 21 and the second mounting bracket 22 are respectively provided with a first Y-direction limiting part and a second Y-direction limiting part to limit the Y-direction displacement of the torsion spring 23. The fixed part 11 and the rotating part 12 are respectively provided with Z-direction mounting parts corresponding to the first mounting bracket 21 and the second mounting bracket 22. The first mounting bracket 21 and the second mounting bracket 22 are each provided with a Z-direction limiting plane mating surface that cooperates with the Z-direction mounting part.

[0049] In this embodiment, the structure is simple and easy to assemble. By changing the fixing mode of the torsion spring 23, the traditional slot-type pressing assembly is modified to a through-shaft mounting through-hole type. With the first and second Y-direction limiting parts located on the first mounting bracket 21 and the second mounting bracket 22, the two ends of the torsion spring 23 are firmly fixed in the first mounting bracket 212 and the second mounting bracket 22, thereby reducing the shaking of the torsion spring 23 during the flipping process and reducing the possibility of abnormal noise caused by shaking. At the same time, it effectively solves the problem of limited pressing space and hand pain during the assembly process of the torsion spring 23. By modifying the fixing mode of the torsion spring 23, the force of the torsion spring 23 is concentrated on the mounting bracket, which can effectively prevent it from crushing the spring limiting ribs on the mounting bracket and the flip cover plate 1. This avoids the problem of increased gap between the flip cover plate 1 and the mounting bracket limiting spring due to crushing of the spring limiting ribs, as well as the problem of aggravated abnormal noise caused by the up and down tapping of the spring.

[0050] Specifically:

[0051] like Figure 4-5 As shown, in the above embodiment, preferably, the two sides of the Z-direction mounting portion on the fixing part 11 and the rotating part 12 are respectively provided with first screw mounting portions 15; the two ends of the first mounting bracket 21 and the two ends of the second mounting bracket 22 are respectively provided with second screw mounting portions that cooperate with the first screw mounting portions 15, and the screw 24 passes through the second screw mounting portion and is screwed onto the first screw mounting portion 15; one end of the Z-direction mounting portion of the fixing part 11 is also provided with a spring limiting portion 16.

[0052] In specific implementation, the fixing part 11 is provided with a first mounting bracket Z-direction limiting plane 13 corresponding to the first mounting bracket 21, and the rotating part 12 is provided with a second mounting bracket Z-direction limiting plane 14 corresponding to the second mounting bracket 22. First screw mounting parts 15 are respectively provided at both ends of the first mounting bracket Z-direction limiting plane 13 and at both ends of the second mounting bracket Z-direction limiting plane 14. In this embodiment, the first screw mounting parts 15 are all BOSS posts. A spring limiting part 16 is also provided on one side of the first mounting bracket Z-direction limiting plane 13.

[0053] like Figure 6-7 As shown, in the above embodiment, preferably, the torsion spring 23 includes a winding portion 231 and a first mounting bracket through-hole matching shaft 232 and a second mounting bracket through-hole matching shaft 233 extending outward from both ends of the winding portion 231. The first mounting bracket through-hole matching shaft 232 near the winding portion 231 forms a Y-direction limiting point matching shaft 234, and the end face of the second mounting bracket through-hole matching shaft 233 forms a Y-direction limiting rib matching surface 235. During actual assembly, the first mounting bracket through-hole matching shaft 232 and the second mounting bracket through-hole matching shaft 233 are respectively inserted into the through-holes on the first mounting bracket 21 and the second mounting bracket 22. The Y-direction limiting point matching shaft 234 and the Y-direction limiting rib matching surface 235 respectively cooperate with the first Y-direction limiting portion and the second Y-direction limiting portion.

[0054] In the above embodiment, preferably, after the first mounting bracket 21 and the fixing part 11 are installed in place, the Y-direction limiting point matching shaft 234 and the spring limiting part 16 are engaged.

[0055] like Figure 8-10As shown, in the above embodiment, preferably, the first mounting bracket 21 includes a Z-direction limiting plane mating surface 213 that mates with the Z-direction limiting plane 13 of the first mounting bracket. Each end of the first mounting bracket 21 is provided with a second screw mounting portion that mates with the first screw mounting portion 15. The second screw mounting portion is a positioning countersunk hole that mates with the BOSS post. The outer surface of the positioning countersunk hole constitutes the screw mounting limiting plane 211 of the first mounting bracket, and a screw mounting hole 212 of the first mounting bracket is formed within the positioning countersunk hole. On the back of the first mounting bracket 21 (the side near the fixing portion 11), a plurality of through holes 214 of the first mounting bracket are provided at intervals along its length. A first mounting bracket spring Y-direction limiting point 215 is also provided on one side of the back of the first mounting bracket 21. The first mounting bracket spring Y-direction limiting point 215 constitutes a first Y-direction limiting portion, and the through-axis direction of the first mounting bracket spring Y-direction limiting point 215 is perpendicular to the through-axis direction of the plurality of through holes 214 of the first mounting bracket. During actual assembly, the Y-direction limiting point of the torsion spring 23 matches the shaft 234 and engages with the Y-direction limiting point 215 of the first mounting bracket spring.

[0056] like Figure 11-13 As shown, in the above embodiment, preferably, the second mounting bracket 22 includes a Z-direction limiting plane mating surface 223 that mates with the Z-direction limiting plane 14 of the second mounting bracket. Both ends of the second mounting bracket 22 are respectively provided with second screw mounting portions that mate with the first screw mounting portion 15. These second screw mounting portions are positioning countersunk holes that mate with the BOSS post. The outer surface of the positioning countersunk hole forms the screw mounting limiting plane 221 of the second mounting bracket, and a screw mounting hole 222 of the second mounting bracket is formed within the positioning countersunk hole. On the back of the second mounting bracket 22 (the side near the rotating part 12), a plurality of through holes 224 of the second mounting bracket are provided at intervals along its length. A second mounting bracket spring Y-direction limiting rib 225 is also provided on one side of the back of the second mounting bracket 22, constituting a second Y-direction limiting portion. During actual assembly, the mating surface of the Y-direction limiting rib of the torsion spring 23 abuts against the second mounting bracket spring Y-direction limiting rib 225.

[0057] In the above embodiments, preferably, the first mounting bracket spring Y-direction limiting point 215 is integrally formed with the first mounting bracket 21; the second mounting bracket spring Y-direction limiting rib 225 is integrally formed with the second mounting bracket 22.

[0058] In the above embodiments, preferably, the number of rotating components 2 is 3, and the 3 rotating components 2 are evenly spaced.

[0059] In the above embodiments, preferably, when the first mounting bracket 21 is assembled with the fixing part 11, the Z-direction limiting plane 13 of the first mounting bracket on the fixing part 11 is in contact with the Z-direction limiting plane mating surface 213 of the first mounting bracket; when the second mounting bracket 22 is assembled with the rotating part 12, the Z-direction limiting plane 14 of the second mounting bracket on the rotating part 12 is in contact with the Z-direction limiting plane mating surface 223 of the second mounting bracket.

[0060] In the above embodiments, preferably, the rotational connection is achieved through a specific rotating component 2. The torsion spring 23 in the rotating component 2 is connected to the first and second mounting brackets through a through-shaft and is provided with a Y-direction limiting part. At the same time, a Z-direction mounting part and a Z-direction limiting plane mating surface are also provided. This structure plays a key role in solving the problem of deformation and warping after humid heat aging. Specifically, in the existing slot-type torsion spring 23 mounting structure, the torsion spring 23 is squeezed between two planes. When subjected to force, the torsion spring 23 flips. Because the material PA66 of the mounting bracket is harder than the material PP+EPDM-TD20 of the flip cover plate, the flip cover plate 1 deforms upward under the spring force when the humid heat aging part is heated. However, in the structure of this embodiment, the torsion spring 23 is connected to the first and second mounting brackets through a through-shaft hole. The force of the modified torsion spring 23 is all on the first and second mounting brackets, which effectively avoids deformation and warping caused by uneven force under humid heat aging environment from the structural level.

[0061] In the above embodiments, preferably, the coordinate system is established based on the vehicle coordinate system, specifically with the direction of the roof and bottom of the vehicle as the Z direction, the direction of the front and rear of the vehicle as the X direction, and the direction of the driver's side and passenger side as the Y direction.

[0062] The assembly method of this embodiment:

[0063] 1. Pre-assembly of rotating component 2 (e.g.) Figure 14 As shown):

[0064] After aligning the first mounting bracket through-hole matching shaft 232 on the torsion spring 23 with the first mounting bracket through-hole 214 on the first mounting bracket 21 and passing through both holes, press down the torsion spring 23 so that the Y-direction limiting point matching shaft 234 on the torsion spring 23 is engaged with the first mounting bracket spring Y-direction limiting point 215 on the first mounting bracket 21.

[0065] Align the shaft 233 of the second mounting bracket through hole on the torsion spring 23 with the shaft 224 of the second mounting bracket on the second mounting bracket 22 and pass through the two holes. Then press hard to make the Y-direction limiting rib matching surface 235 of the torsion spring 23 fit with the Y-direction limiting rib 225 of the second mounting bracket spring on the second mounting bracket 22. At this time, the pre-assembly of the rotating component 2 is completed.

[0066] 2. The flip cover 1 and the rotating component 2 are assembled to form the flip cover assembly:

[0067] Align the first mounting bracket screw mounting hole 212 on the first mounting bracket 21 in the rotating component 2 with the first screw mounting part 15 on the fixing part 11 on the flip cover plate 1. At this time, the spring limiting part 16 on the flip cover plate 1 is in contact with the Y-direction limiting point matching shaft 234 on the torsion spring 23.

[0068] Tighten the two screws at 24 points. After tightening, the Z-direction limiting plane 13 of the first mounting bracket on the flip cover plate 1 fits into the Z-direction limiting plane mating surface 213 of the first mounting bracket on the first mounting bracket 21.

[0069] Align the second mounting bracket screw mounting hole 222 on the second mounting bracket 22 in the rotating component 2 with the first screw mounting part 15 on the rotating part 12 of the flip cover plate 1.

[0070] And tighten the two screws 24, so that the Z-direction limiting plane 14 of the second mounting bracket on the flip cover plate 1 after tightening fits with the Z-direction limiting plane mating surface 223 of the second mounting bracket on the second mounting bracket 22;

[0071] 3. Assembly of the remaining rotating parts 2 and the flip cover 1.

[0072] like Figure 15 As shown, the installation structure disclosed in this embodiment is intended for concealing unsightly features after the rear seat angle is adjusted. The rear seat has three states: normal seat position A, seat tilted back 16° position B, and seat folded down position C.

[0073] When the seat is in its normal state A, the flip cover 100 that matches the normal state of the seat is as follows: the first mounting bracket through-shaft hole on the torsion spring 23 matches the shaft 232 with the shaft 214 of the first mounting bracket on the first mounting bracket 21; at the same time, the Y-direction limiting point on the torsion spring 23 matches the shaft 234 with the Y-direction limiting point 215 of the first mounting bracket spring on the first mounting bracket 21; the second mounting bracket through-shaft hole on the torsion spring 23 matches the shaft 233 with the shaft 224 of the second mounting bracket on the second mounting bracket 22; at the same time, the Y-direction limiting rib on the torsion spring 23 matches the surface 235 with the Y-direction limiting rib 225 of the second mounting bracket spring on the second mounting bracket 22. At this time, the rotating component 2 is in a positioning state.

[0074] The fixing part 11 on the flip cover 1 is fixed to the first mounting bracket 21 by screws 24, and the entire Z-direction limiting spring of the Y-direction limiting point matching shaft 234 on the torsion spring 23 is fixed by the spring limiting part 16 on the flip cover 1; the rotating part 12 on the flip cover 1 is fixed to the second mounting bracket 22 by screws 24.

[0075] When the seat is in the reclined position C, the flip cover 300 that matches the reclined position is in the following state: the rotating part 12 on the flip cover 1 flips the rotating part 12 of the flip cover assembly upward by flipping the seat, and at this time the torsion spring 23 gives the rotating part 12 of the flip cover assembly a downward pulling force.

[0076] When the seat is flipped back 16° in state B, the state of the flip cover 200 that matches the 16° flipped back state of the seat is as follows: the rotating part 12 on the flip cover 1 flips down by flipping the seat, and at this time the torsion spring 23 gives the rotating part 12 on the flip cover 1 an upward pulling force.

[0077] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
