Description

Technical Field

[0001] The utility model belongs to the technical field of luggage box covers, and more specifically relates to a box cover inner plate, a luggage box and a vehicle. Background Art

[0002] The trunk lid of a car is mainly used to cover the internal space of the trunk. The trunk usually contains items such as on-board tools, electrical components, and spare tires. The lid seals the opening of the trunk body to prevent the items in the trunk from being exposed and to ensure a neat appearance of the trunk.

[0003] Most of the existing car trunk covers are made of steel plates or aluminum plates that are welded together. Due to the large number of parts and the high density of the steel plates, the trunk cover is heavy, which is not conducive to the lightweight of the car body. In addition, the stamping process is complex and requires a lot of investment, which is not conducive to reducing costs. In order to reduce the weight of the trunk cover, some car companies have begun to use lightweight materials instead of metal trunk covers, such as plastic or composite materials. However, compared with metal trunk covers, the mechanical properties of plastic or composite materials are insufficient, such as stiffness and strength. In long-term use, the inner plate of the trunk cover is prone to deformation or even cracks, which in turn causes the inner plate of the trunk cover to crack, affecting the normal use of the trunk cover.

In the claims, specification and the above drawings of the present utility model, if the terms "including", "having" and their variations are used, it is intended to mean "including but not limited to".

[0041] It should be noted that “inside” refers to the side close to the center of the inner panel body, and the opposite is “outside”.

[0042] Please also read Figures 1 to 4 The box cover inner plate, luggage box and vehicle provided by the utility model are now described. The box cover inner plate includes an inner plate body and a reinforcement structure. The inner plate body includes a main body 2 and a connecting flange 1 arranged around the outer periphery of the main body 2. The connecting flange 1 is connected to the outer plate. The main body 2 is recessed toward the side away from the outer plate. The main body 2 includes a main plate area 201 and a reinforcement area 202 arranged around the outer periphery of the main plate area 201. The main plate area 201 protrudes from the reinforcement area 202 toward the side close to the outer plate. The connecting flange 1 is connected to the outer edge of the reinforcement area 202. The reinforcement structure is connected to the reinforcement area 202 and is arranged around the outer periphery of the main plate area 201.

[0043] Compared with the prior art, the box cover inner plate provided by the utility model is connected to the outer plate through the connecting flange 1. Since the main body 2 is recessed toward the side away from the outer plate, after the outer plate is connected to the connecting flange 1, a receiving cavity is formed between the main body 2 and the outer plate. The main board area 201 in the middle part of the main body 2 protrudes toward the side close to the outer plate, forming a step-shaped protrusion in the receiving cavity, avoiding interference with the outer plate, and increasing the strength and anti-deformation ability of the main body 2 without increasing the thickness of the inner plate body. The reinforcement structure is arranged at the periphery of the main board area 201 to strengthen the strength of the reinforcement area 202. On the one hand, it can avoid the inner plate body 2 from cracking due to the impact force during the driving of the vehicle, and on the other hand, it can avoid the deformation of the inner plate body 2 caused by the long-term opening and closing of the box cover. The utility model increases its own strength by designing a convex and concave structure on the inner plate body, thereby improving the strength and anti-deformation ability of the inner plate body. At the same time, the reinforcement structure is designed to be located in the receiving cavity between the inner plate and the outer plate, which will not occupy the space in the box body, and also ensures the neatness and beauty of the appearance of the luggage box. In addition, since the reinforcement structure is arranged around the outer periphery of the main board area 201, not only the strength of the entire reinforcement area 202 is enhanced, but also the strength of each part is ensured to be uniform, thereby avoiding the problem of local stress concentration and subsequent damage after being subjected to force.

[0044] Optionally, an annular sealing area 204 is provided on the side of the inner plate body facing away from the outer plate.

[0045] Optionally, the reinforcement structure and the inner panel body may be an integral structure or a separate structure.

[0046] In some embodiments, see Figures 1 to 4 The main body 2 is also provided with a separation rib 203, which divides the reinforcement area 202 into an installation space 2022 and a reinforcement space 2021. The installation space 2022 is surrounded by the outer periphery of the main board area 201, and the reinforcement space 2021 is surrounded by the outer periphery of the installation space 2022.

[0047] The separation rib 203 is a closed rib body connected end to end, which can not only separate the reinforcement area 202 from the inside to the outside into the installation space 2022 and the reinforcement space 2021, but also further increase the strength of the reinforcement area 202 and reduce the probability of the reinforcement area 202 being deformed or cracked due to stress.

[0048] Optionally, the installation space 2022 is used to install hinges and locks.

[0049] In some embodiments, see Figures 1 to 4The reinforcement structure includes a first reinforcement component 3, a second reinforcement component 4 and a third reinforcement component 5. The first reinforcement component 3 is arranged in the reinforcement space 2021 and abuts against the separation rib 203 and the connection flange 1 respectively; the second reinforcement component 4 is arranged in the installation space 2022 and abuts against the main board area 201 and the separation rib 203 respectively; the third reinforcement component 5 is arranged in the reinforcement space 2021 and the installation space 2022 and abuts against the main board area 201 and the connection flange 1 respectively.

[0050] The first reinforcement component 3 is arranged in the reinforcement space 2021 to increase the strength of the reinforcement space 2021, and at the same time, it can also ensure the relative stability of the reinforcement space 2021 and the installation space 2022 after being subjected to force, and reduce the probability of deformation. The second reinforcement component 4 is arranged in the installation space 2022 to reduce the probability of deformation or fracture of the installation space 2022 after being subjected to force. At the same time, since the installation space 2022 is installed with components such as hinges and locks, it is easy to deform. Therefore, the second reinforcement component 4 can also increase the strength of the installation space 2022 and provide effective support for the hinges and locks. The third reinforcement member is arranged in the reinforcement space 2021 and the installation space 2022 to increase the strength and rigidity of the entire reinforcement space 2021 and the installation hole, and is distributed to abut against the main board area 201 and the connecting flange 1 to ensure that the reinforcement area 202 does not deform.

[0051] In some embodiments, see Figures 1 to 4 The first reinforcement component 3 includes a support module and a reinforcement module. The support module includes a plurality of support members arranged in sequence. The support member includes two cross-arranged support sheets 301. The inner end of each support sheet 301 abuts against the separation rib 203, and the outer end abuts against the connecting flange 1; the reinforcement module includes a plurality of reinforcement sheets 302 arranged in sequence at intervals. The inner end of the reinforcement sheet 302 abuts against the separation rib 203 and / or the outer end abuts against the connecting flange 1.

[0052] The support member, the connecting flange 1, and the separation rib 203 enclose a closed reinforcement space 2021, which improves the strength and rigidity of the reinforcement space. In addition, the support member includes two cross-arranged support sheets, which have strong anti-deformation ability and are not easy to deform or break after being subjected to force. The reinforcement sheet 302 limits the reinforcement space 2021 in the inner and outer directions. At the same time, the reinforcement sheet 302 is simple in structure relative to the support member, avoiding the problem of excessive weight of the inner plate of the box cover caused by setting too many support members.

[0053] In some embodiments, see Figures 1 to 4The second reinforcement component 4 includes a plurality of reinforcement modules spaced apart in sequence, each reinforcement module includes a plurality of reinforcement sheets 401 and connecting sheets 402, the plurality of reinforcement sheets 401 are spaced apart in sequence, the inner end of the reinforcement sheet 401 abuts against the main board area 201, and the outer end abuts against the separation rib 203; the plurality of reinforcement sheets 401 are all connected to the connecting sheet 402, and the plurality of reinforcement sheets 401 are cross-arranged with the connecting sheet 402.

[0054] The reinforcing sheet 401 ensures that the installation space 2022 does not deform in the inner and outer directions. The connecting sheet 402 is distributed and connected to multiple reinforcing sheets 401, so that multiple reinforcing sheets 401 are connected to form an integral structure, further increasing the strength and anti-deformation ability of the reinforcing module.

[0055] As another specific embodiment of the reinforcement module, the second reinforcement component 4 also includes a fastening plate 403 connecting two adjacent reinforcement modules. The fastening plate 403 is connected to the two adjacent reinforcement modules to form an integral structure. Compared with the multiple reinforcement modules arranged in a dispersed manner, the strength and rigidity thereof are further increased, thereby avoiding the problem of deformation of the inner panel of the box cover during the process of opening the box cover.

[0056] In some embodiments, see Figures 1 to 4 The third reinforcing component 5 includes a plurality of extension pieces 502 that are spaced apart from each other in sequence. The inner ends of the extension pieces 502 abut against the outer edges of the main board area 201 , and the outer ends are located in the installation space 2022 .

[0057] The extension pieces 502 are distributed in the main board area 201 and the installation space 2022, so as to strengthen the overall structure of the area and avoid damage caused by insufficient local strength.

[0058] As another specific implementation of the third reinforcement component 5, please refer to Figures 1 to 4 The third reinforcing component 5 also includes a limiting module 501, which includes a plurality of limiting plates 5011 arranged in sequence and at intervals, wherein the inner end of the limiting plate 5011 abuts against the outer edge of the main board area 201, and the outer end abuts against the connecting flange 1, and further includes a connecting strip 5012 connecting the plurality of limiting plates 5011, and the connecting strip 5012 is arranged at an angle to the limiting plate 5011.

[0059] The limiting module 501 connects a plurality of limiting pieces 5011 to form an overall structure through a connecting strip 5012, thereby avoiding relative displacement between adjacent limiting pieces 5011 and ensuring relative stability and strength of the overall structure. In this embodiment, the limiting module 501 and the extension module are provided at the same time, thereby ensuring overall strength and rigidity while avoiding the problem of weight increase caused by providing all limiting modules 501.

[0060] In some embodiments, see Figures 1 to 4The main board area 201 is provided with a plurality of weight-reducing holes 2011 , and the inner plate of the box cover further includes a reinforcing sheet 2012 arranged in the main board area 201 , and the reinforcing sheet 2012 is located on the outside of the weight-reducing holes 2011 .

[0061] The weight-reducing hole 2011 can reduce the weight of the inner plate body, but the strength of the peripheral area of ​​the weight-reducing hole 2011 will be reduced, and it is easy to deform after being subjected to force. Therefore, a reinforcing plate 2012 is set outside the weight-reducing hole 2011, and the main board area 201 is located in the peripheral area of ​​the weight-reducing hole 2011 to reduce the probability of deformation.

[0062] It should be noted that, due to the tail strip structure of the reinforcing plate 2012, the volume and weight are smaller than the portion removed from the main board area 201 (the area where the weight-reducing holes 2011 are formed), so the overall weight of the inner plate body is still reduced.

[0063] In some embodiments, see Figures 1 to 4 The inner panel body has a hinge mounting position and a lock mounting position, the hinge mounting position is recessed toward the side away from the outer panel, and the lock mounting position is protruding toward the side close to the outer panel.

[0064] The hinge mounting position and the lock mounting position need to be installed and fixed with components, so the strength requirement is relatively high. This embodiment increases the strength and reduces the probability of deformation by setting a concave or convex structure. In addition, since the hinge mounting position is concave toward the side away from the outer panel and the lock mounting position is convex toward the side close to the outer panel, stress offset can be achieved during processing to avoid breakage.

[0065] Based on the same inventive concept, the utility model also provides a luggage case, which comprises any one of the above-mentioned inner panels of the luggage cover.

[0066] The luggage box provided by the utility model adopts the above-mentioned box cover inner plate, which is connected to the outer plate through the connecting flange 1. Since the main body 2 is recessed toward the side away from the outer plate, after the outer plate is connected to the connecting flange 1, a receiving cavity is formed between the main body 2 and the outer plate. The main board area 201 in the middle part of the main body 2 protrudes toward the side close to the outer plate, forming a step-shaped protrusion in the receiving cavity, avoiding interference with the outer plate, and at the same time increasing the strength and anti-deformation ability of the main body 2 without increasing the thickness of the inner plate body. The reinforcement structure is arranged at the periphery of the main board area 201 to strengthen the strength of the reinforcement area 202. On the one hand, it can avoid the inner plate body 2 from cracking due to the impact force during the driving process of the vehicle, and on the other hand, it can avoid the deformation of the inner plate body 2 caused by the long-term opening and closing of the box cover. The utility model increases its own strength by designing a convex and concave structure on the inner plate body, thereby improving the strength and anti-deformation ability of the inner plate body. At the same time, the reinforcement structure is designed to be located in the receiving cavity between the inner plate and the outer plate, which will not occupy the space in the box body, and also ensures the neatness and beauty of the appearance of the luggage box. In addition, since the reinforcement structure is arranged around the outer periphery of the main board area 201, not only the strength of the entire reinforcement area 202 is enhanced, but also the strength of each part is ensured to be uniform, thereby avoiding the problem of local stress concentration and subsequent damage after being subjected to force.

[0067] Based on the same inventive concept, the utility model also provides a vehicle, which includes the above-mentioned luggage box.

[0068] The vehicle provided by the utility model adopts the above-mentioned luggage box, which is connected to the outer panel through the connecting flange 1. Since the main body 2 is recessed toward the side away from the outer panel, after the outer panel is connected to the connecting flange 1, a receiving cavity is formed between the main body 2 and the outer panel. The main board area 201 in the middle part of the main body 2 protrudes toward the side close to the outer panel, forming a step-shaped protrusion in the receiving cavity, avoiding interference with the outer panel, and at the same time increasing the strength and anti-deformation ability of the main body 2 without increasing the thickness of the inner panel body. The reinforcement structure is arranged at the periphery of the main board area 201 to strengthen the strength of the reinforcement area 202. On the one hand, it can avoid the inner panel body 2 from cracking due to the impact force during the driving of the vehicle, and on the other hand, it can avoid the deformation of the inner panel body 2 caused by long-term opening and closing of the box cover. The utility model increases its own strength by designing a convex and concave structure for the inner panel body, thereby improving the strength and anti-deformation ability of the inner panel body. At the same time, the reinforcement structure is designed to be located in the receiving cavity between the inner panel and the outer panel, which will not occupy the space in the box body, and also ensures the neatness and beauty of the appearance of the luggage box. In addition, since the reinforcement structure is arranged around the outer periphery of the main board area 201, not only the strength of the entire reinforcement area 202 is enhanced, but also the strength of each part is ensured to be uniform, thereby avoiding the problem of local stress concentration and subsequent damage after being subjected to force.
