Description

Technical Field

[0001] This utility model relates to the field of side panel technology, specifically to a vehicle side panel assembly and a vehicle. Background Technology

[0002] During vehicle operation, the operation of the engine and motor, the friction between the tires and the ground, and the airflow generate various noises. These noises propagate in the cavities of the vehicle body side panels (which may include A-pillars, B-pillars, C-pillars, and D-pillars, etc.) and may cause resonance phenomena within the cavities, resulting in a decrease in NVH (noise, vibration, and harshness) performance and a significant reduction in ride comfort.

[0003] In related technologies, the cavity of the vehicle body side panel is usually equipped with an expansion sealing block. After being heated in an electrophoretic drying oven (the heating temperature can be 140℃~180℃, and the heating duration is about 20 minutes), the expansion sealing block expands, thereby sealing the cavity and effectively blocking the transmission of air noise and structural noise in the cavity, achieving sound insulation and noise reduction. This structure has the functions of sealing, vibration reduction and noise reduction.

[0004] However, because the side panels of the vehicle body need to fit with the roof, the top of the side panels has an outward-bending section to cover the seam between the side panels and the roof in the left and right directions of the vehicle. To balance aesthetics and structural strength, the design of the bending section causes uneven thickness of the cavity. That is, the cavity thickness in the area away from the bending section is too small (about 2mm), while the cavity thickness in the area where the bending section is located is too large (more than 20mm). If the expansion sealing block is too thick, it is easy to interfere with the side panel, resulting in a difficult side panel assembly. If the expansion sealing block is too thin, it is difficult to fully fill the cavity. Utility Model Content

[0005] This invention provides a vehicle side panel assembly and a vehicle to solve the problem that expansion sealing blocks are difficult to simultaneously meet the dual requirements of avoiding assembly interference and achieving effective cavity sealing.

[0006] In a first aspect, the present invention provides a vehicle side panel assembly, comprising: a housing, including an outer plate, an inner plate, and a reinforcing plate, the reinforcing plate being connected between the outer plate and the inner plate, a cavity being defined between the outer plate and the reinforcing plate, the outer plate having an outwardly bent section to form a positioning groove suitable for mating with a vehicle top cover; and an expansion member disposed within the cavity, the expansion member including a base and a thickened portion, the base being connected to the reinforcing plate, the thickened portion being connected to the side of the base facing away from the reinforcing plate, the thickened portion being located at one end of the base near the bent section, and the thickened portion having a deformation cavity.

[0007] Beneficial effects: By connecting the base to the reinforcing plate, the relative positions of the expansion member and the reinforcing plate are fixed during the assembly and heating processes of the vehicle side panel assembly, ensuring effective sealing of the cavity by the expansion member. During the assembly of the outer plate, inner plate, and reinforcing plate, the thickened portion can deform towards the deformation cavity, reducing its height and the probability of interference between the outer plate and the thickened portion, ensuring smooth assembly of the shell. After shell assembly, the thickened portion rebounds to its original shape. At this point, the expansion member can be heated, and the thickened portion fills the space near the bent section, while the base fills the remaining areas of reduced thickness within the cavity. This ensures that areas of varying thickness within the cavity are fully filled and sealed, meeting the dual requirements of avoiding assembly interference and achieving effective cavity sealing.

[0008] In one alternative embodiment, the deformation cavity extends through the thickened portion along the width direction of the thickened portion.

[0009] Beneficial effects: The thickened section has a larger deformable space, which helps to improve its deformation capacity. During the assembly of the outer panel and reinforcing plate, the thickened section is significantly compressed and deformed, increasing the ease of assembly. In addition, during electrophoresis on the shell, the electrophoretic solution can flow smoothly through the deformation cavity, ensuring sufficient electrophoresis within the cavity and guaranteeing the anti-corrosion effect.

[0010] In one alternative embodiment, the thickened portion has a first end and a second end, the first end being the end of the thickened portion away from the bent section, and the second end being the end of the thickened portion close to the bent section. The first end is fixedly connected to the base, and the second end is fixedly connected to or detachably connected to the base.

[0011] Beneficial effects: By fixing both the first and second ends to the base, the connection strength between the thickened portion and the base is high, which helps to increase the reliability of the relative position between the thickened portion and the base. By fixing the first end to the base and detachably connecting the second end to the base, the second end remains connected to the base during the assembly of the shell, and separates from the base during thermal expansion, allowing the thickened portion to better fill areas with larger cavity thicknesses.

[0012] In one alternative embodiment, the base has a third end disposed near the bent section, and the end face of the third end is spaced apart from the second end.

[0013] Beneficial effects: Avoids setting the bending section too close to the end face of the third end, ensuring that the second end of the expansion component can be reliably connected to the base during processing, and improving the product yield of the expansion component.

[0014] In one optional embodiment, the thickened portion includes: an inclined segment, the first end of which is formed in the inclined segment, and the distance between the inclined segment and the base gradually increases in the thickness direction of the base from the first end to the second end; and a connecting segment, the second end of which is formed in the connecting segment, and the connecting segment is connected to the inclined segment and forms an arc transition.

[0015] Beneficial effects: The closer to the bending section, the greater the distance between the inclined section and the base in the thickness direction of the base. The thickened part can better adapt to the shape of the cavity to ensure the effectiveness of the expansion component in filling the cavity, improve the sealing of the cavity, and reduce noise.

[0016] In one alternative embodiment, the foaming ratio of the thickened portion is greater than the foaming ratio of the base portion.

[0017] Beneficial effects: Since the cavity near the bending section is relatively thick, by increasing the foaming ratio of the thickened part, it is possible to achieve efficient filling of the thicker area of ​​the cavity, ensuring the sealing of the cavity. In addition, the foaming ratio of the base is reduced, which can reduce the cost of the expansion component while meeting the filling needs of other areas of the cavity.

[0018] In one optional embodiment, the foaming ratio of the thickened portion is between 8 and 12 times; and / or, the foaming ratio of the base portion is between 5 and 8 times.

[0019] Beneficial effects: The foaming ratio of the thickened portion is not less than 8 times, ensuring a sufficiently large foaming ratio to effectively fill the space near the bending section and improve the cavity's sealing performance. A foaming ratio of not more than 12 times for the thickened portion reduces its cost. The foaming ratio of the base is not less than 5 times, ensuring effective filling of other areas within the cavity. A foaming ratio of not more than 8 times for the base reduces its cost.

[0020] In one optional embodiment, the vehicle side panel assembly further includes: a plurality of fasteners, the fasteners passing through the base and the reinforcing plate, the plurality of fasteners being spaced apart along the length direction of the base, and the fasteners being spaced apart from the thickening.

[0021] Beneficial effects: By setting multiple fasteners, the connection reliability between the expansion member and the reinforcing plate can be improved. In addition, the fasteners will not be exposed from the shell, which improves the aesthetics of the vehicle side panel assembly and reduces the probability of interference between the vehicle side panel assembly and the outside world. Furthermore, the fasteners and the thickened part are spaced apart to avoid interference between the fasteners and the thickened part, which not only prevents the thickened part from being damaged by friction from the fasteners, but also improves the ease of installation of the fasteners.

[0022] In one optional embodiment, the base has a receiving groove on the side facing away from the reinforcing plate, the fixing member includes a fixing post and a fixing cap, the fixing post passes through the base and the reinforcing plate, the fixing cap is connected to the fixing post, the fixing cap is located in the receiving groove, and the cross-sectional area of ​​the fixing cap is larger than the cross-sectional area of ​​the fixing post.

[0023] Beneficial effects: By setting a fixing post, the relative position between the base and the reinforcing plate can be fixed. By setting a fixing cap abutting against the side of the base facing away from the reinforcing plate, the size of the fixing member inserted into the base and the reinforcing plate can be limited, preventing the fixing member from detaching from the base and the reinforcing plate. Furthermore, by setting a receiving groove, at least a portion of the fixing cap can be accommodated, reducing the size of the fixing cap protruding from the side of the base facing away from the reinforcing plate, ensuring the fit between the base and the outer shell after expansion, and improving the sealing effect of the expansion member on the cavity.

[0024] Secondly, this utility model also provides a carrier, including: the aforementioned carrier side panel assembly; and a carrier top cover, the carrier top cover being fitted into the positioning groove.

[0025] Beneficial effects: The vehicle of this utility model embodiment, through the above-mentioned vehicle side panel assembly, can reduce noise, improve riding comfort, and has high production efficiency. Attached Figure Description

[0035] 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 embodiments of this utility model, not all embodiments. 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.

[0036] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, in one aspect, a vehicle side enclosure assembly 1 is provided, which includes a housing 100 and an expansion member 200.

[0040] The housing 100 includes an outer plate 110, an inner plate 120 and a reinforcing plate 130. The reinforcing plate 130 is connected between the outer plate 110 and the inner plate 120. A cavity 101 is defined between the outer plate 110 and the reinforcing plate 130. The outer plate 110 has an outwardly bent section 111 to form a positioning groove 112 suitable for mating with the top cover of a vehicle.

[0041] The expansion member 200 is disposed in the cavity 101. The expansion member 200 includes a base 210 and a thickened portion 220. The base 210 is connected to the reinforcing plate 130. The thickened portion 220 is connected to the side of the base 210 facing away from the reinforcing plate 130. The thickened portion 220 is located at one end of the base 210 near the bending section 111. The thickened portion 220 is provided with a deformation cavity 230.

[0042] The vehicle side panel assembly 1 may include A-pillars, B-pillars, C-pillars, and D-pillars, all of which can mate with the vehicle roof. An expansion member 200 may be provided at least one of the A-pillars, B-pillars, C-pillars, and D-pillars. By providing the bending section 111, the left and right sides of the vehicle roof can be partially obscured, reducing the probability of observing the seam between the vehicle roof and the vehicle side panel assembly 1, thus improving aesthetics. Furthermore, the bending section 111 increases the structural strength of the shell 100.

[0043] In addition, the deformation cavity 230 can be provided on the side of the thickened portion 220 facing the base portion 210, and the base portion 210 covers part of the opening of the deformation cavity 230.

[0044] In the vehicle side enclosure assembly 1 of this utility model embodiment, by connecting the base 210 to the reinforcing plate 130, the relative positions of the expansion member 200 and the reinforcing plate 130 are fixed during the assembly and heating process of the vehicle side enclosure assembly 1, ensuring that the expansion member 200 effectively seals the cavity 101.

[0045] When the outer plate 110, inner plate 120 and reinforcing plate 130 are assembled, the thickened part 220 can deform in the direction of the deformation cavity 230, reducing the height of the thickened part 220 and reducing the probability of interference between the outer plate 110 and the thickened part 220, ensuring the smooth assembly of the shell 100. After the shell 100 is assembled, the thickened part 220 rebounds back to its own shape. At this time, the expansion member 200 can be heated, for example by baking. The thickened part 220 fills the space near the bending section 111, and the base 210 fills the remaining areas of the cavity 101 with reduced thickness, ensuring that areas of different thicknesses in the cavity 101 can be fully filled and sealed, meeting the dual requirements of avoiding assembly interference and achieving effective sealing of the cavity 101.

[0046] In some embodiments, such as Figures 2-4 , Figure 6 As shown, the deformation cavity 230 extends through the thickened portion 220 along its width. This provides a larger deformable space for the thickened portion 220, improving its deformability. During assembly of the outer plate 110 and the reinforcing plate 130, the thickened portion 220 is significantly compressed and deformed, increasing the ease of assembly. Furthermore, during electrophoresis in the shell 100, the electrophoretic solution can flow smoothly through the deformation cavity 230, ensuring sufficient electrophoresis within the cavity 101 and guaranteeing corrosion protection.

[0047] In some embodiments, such as Figures 3-4 As shown, the thickened portion 220 has a first end 221 and a second end 222. The first end 221 is the end of the thickened portion 220 away from the bending section 111, and the second end 222 is the end of the thickened portion 220 close to the bending section 111. The first end 221 is fixedly connected to the base 210, and the second end 222 is fixedly connected to the base 210 or detachably connected.

[0048] By fixing both the first end 221 and the second end 222 to the base 210, the connection strength between the thickened part 220 and the base 210 is high, which helps to increase the reliability of the relative position between the thickened part 220 and the base 210.

[0049] By fixing the first end 221 to the base 210 and detachably connecting the second end 222 to the base 210, the second end 222 remains connected to the base 210 during the assembly of the housing 100. During subsequent thermal expansion, the second end 222 separates from the base 210, and the thickened portion 220 can better fill the area with a larger thickness in the cavity 101. The second end 222 and the base 210 can be connected by an adhesive. The viscosity of the adhesive decreases after heating, thereby achieving the separation of the second end 222 and the base 210.

[0050] Furthermore, such as Figures 3-4 As shown, the base 210 has a third end 211, which is located close to the bending section 111. The end face of the third end 211 and the second end 222 are spaced apart. This avoids the bending section 111 being too close to the end face of the third end 211, ensuring that the second end 222 of the expansion member 200 can be reliably connected to the base 210 during processing, thereby improving the product yield of the expansion member 200.

[0051] In some embodiments, such as Figure 3As shown, the thickened portion 220 includes an inclined section 223 and a connecting section 224. A first end 221 is formed in the inclined section 223, and from the first end 221 to the second end 222, the distance between the inclined section 223 and the base 210 in the thickness direction of the base 210 gradually increases. The second end 222 is formed in the connecting section 224, which connects to the inclined section 223 and forms an arc-shaped transition.

[0052] In other words, the closer to the bending section 111, the greater the distance between the inclined section 223 and the base 210 in the thickness direction of the base 210. The thickened section 220 can better adapt to the shape of the cavity 101 to ensure the effectiveness of the expansion member 200 in filling the cavity 101, improve the sealing of the cavity 101, and reduce noise.

[0053] By connecting the inclined section 223 and the connecting section 224 with an arc-shaped transition, the overall stress is more evenly distributed when the thickened portion 220 expands, avoiding stress concentration at the connection point of the inclined section 223 and the connecting section 224, and reducing the probability of damage to the thickened portion 220. Alternatively, the connecting section 224 can also be constructed in an arc shape to ensure even stress distribution, thereby reducing the probability of damage to the thickened portion 220.

[0054] In some embodiments, the expansion ratio of the thickened portion 220 is greater than that of the base portion 210, that is, during the heating process, the base portion 210 has a smaller degree of expansion, while the thickened portion 220 has a larger degree of expansion.

[0055] Since the cavity 101 near the bending section 111 is relatively thick, by increasing the foaming ratio of the thickened part 220, the thicker area of ​​the cavity 101 can be efficiently filled, ensuring the sealing of the cavity 101 and reducing noise transmission efficiency. Furthermore, the foaming ratio of the base 210 is reduced, which can reduce the cost of the expansion component 200 while meeting the filling requirements of other areas of the cavity 101.

[0056] Specifically, the expansion ratio of the thickened portion 220 is between 8 and 12 times, wherein the expansion ratio of the thickened portion 220 can be 8, 9, 10, 11, or 12 times. The expansion ratio of the base portion 210 is between 5 and 8 times, wherein the expansion ratio of the base portion 210 can be 5, 6, 7, or 8 times.

[0057] Thus, the foaming ratio of the thickened portion 220 is not less than 8 times, ensuring that the foaming ratio of the thickened portion 220 is large enough to effectively fill the space near the bent section 111 and improve the sealing performance of the cavity 101. Furthermore, the foaming ratio of the thickened portion 220 is not higher than 12 times, which can reduce the cost of the thickened portion 220. The foaming ratio of the base portion 210 is not less than 5 times, ensuring that the base portion 210 effectively fills other areas within the cavity 101. Furthermore, the foaming ratio of the base portion 210 is not higher than 8 times, which can reduce the cost of the base portion 210.

[0058] In some embodiments, such as Figures 1-6 As shown, the vehicle side panel assembly 1 also includes a plurality of fasteners 300, which pass through the base 210 and the reinforcing plate 130. The plurality of fasteners 300 are spaced apart along the length of the base 210, and the fasteners 300 are spaced apart from the thickened portion 220.

[0059] The fastener 300 and the thickened portion 220 are spaced apart along the length of the base 210 to ensure that the width of the thickened portion 220 is the same as the width of the base 210, thereby improving the filling effect of the thickened portion 220 on the cavity 101.

[0060] By setting multiple fasteners 300, the connection reliability between the expansion member 200 and the reinforcing plate 130 can be improved. In addition, the fasteners 300 will not be exposed from the housing 100, which improves the aesthetics of the vehicle side panel assembly 1 and reduces the probability of interference between the vehicle side panel assembly 1 and the outside world. Furthermore, the fasteners 300 and the thickened part 220 are spaced apart to avoid interference between the fasteners 300 and the thickened part 220. This not only prevents the thickened part 220 from being damaged by friction from the fasteners 300, but also improves the ease of installation of the fasteners 300.

[0061] Furthermore, the base 210 has a receiving groove 240 on the side facing away from the reinforcing plate 130. The fastener 300 includes a fixing post 310 and a fixing cap 320. The fixing post 310 passes through the base 210 and the reinforcing plate 130. The fixing cap 320 is connected to the fixing post 310 and is located in the receiving groove 240. The cross-sectional area of ​​the fixing cap 320 is larger than the cross-sectional area of ​​the fixing post 310.

[0062] By setting the fixing post 310, the relative position between the base 210 and the reinforcing plate 130 can be fixed. By setting the fixing cap 320 to abut against the side of the base 210 facing away from the reinforcing plate 130, the size of the fixing member 300 inserted into the base 210 and the reinforcing plate 130 can be limited, preventing the fixing member 300 from detaching from the base 210 and the reinforcing plate 130. Furthermore, by setting the receiving groove 240, at least a portion of the fixing cap 320 can be accommodated, reducing the size of the fixing cap 320 protruding from the side of the base 210 facing away from the reinforcing plate 130, ensuring the fit between the base 210 and the outer shell after expansion, and improving the sealing effect of the expansion member 200 on the cavity 101.

[0063] According to an embodiment of the present invention, another aspect provides a vehicle, including the aforementioned vehicle side panel assembly 1 and vehicle top cover, the vehicle top cover fitting into the positioning groove 112. The vehicle can be a vehicle or a low-altitude aircraft, or other means of transportation capable of carrying people or goods.

[0064] The vehicle of this utility model embodiment, through the aforementioned vehicle side panel assembly 1, not only reduces noise and improves riding comfort, but also has high production efficiency.

[0065] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
