[0023] The embodiments of the utility model will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as a limitation of the utility model.
[0024] The following will be described with reference toFigures 1-3 The vehicle roof 10 according to the embodiments of the present application can be used in a vehicle with a sunroof, and a separation layer 2 is arranged between a roof body 1 and a fabric layer 3 to prevent the fabric layer 3 from being cut by a blade during an edge cutting operation, thereby reducing the risk of damage to the fabric layer 3 caused by cutting.
[0025] Referring to Figures 1-3 As shown in the drawings, the vehicle roof 10 according to the embodiments of the present application comprises a roof body 1, a separation layer 2 and a fabric layer 3. The roof body 1 has a sunroof area 20. The separation layer 2 is arranged on the inner side of the roof body 1 and covers the sunroof area 20. The fabric layer 3 is arranged on the side of the separation layer 2 away from the roof body 1 and is fixedly connected to the roof body 1.
[0026] The roof 10 can be arranged on the inner side of the roof of a vehicle. The roof 10 can have the functions of sound absorption, heat insulation and decoration. The roof body 1, the separation layer 2 and the fabric layer 3 of the roof 10 are arranged in sequence in the thickness direction of the roof 10, that is, the separation layer 2 is arranged between the roof body 1 and the fabric layer 3. The roof body 1 can be fixedly connected to the roof of the vehicle. The roof body 1 can be connected to the vehicle by clamping or bonding. The fabric layer 3 is arranged on the side of the separation layer 2 away from the roof body 1. The fabric layer 3 is fixedly connected to the roof body 1. The fabric layer 3 and the roof body 1 can be connected by bonding, clamping or fasteners. The fasteners can be nails, paper clips or the like.
[0027] It should be noted that the roof 10 can be formed by molding. Before the molding of the roof 10, the size of the separation layer 2 needs to be designed according to the size of the sunroof of the vehicle. The size of the separation layer 2 is greater than that of the sunroof area 20, and the separation layer 2 covers the sunroof area 20. After molding, a part of the structure of the roof body 1 can be fixedly connected to the separation layer 2, and another part of the structure of the roof body 1 can be fixedly connected to the fabric layer 3. Before the roof 10 is installed on the vehicle, the roof 10 needs to be pre-cut. The size of the pre-cut is smaller than that of the sunroof area 20. In the direction of the plane on which the roof 10 is arranged, the pre-cut is within the sunroof area 20. After the pre-cut, the roof body 1 and the fabric layer 3 both have excess parts. Then, an edge cutting operation is performed according to the size of the sunroof area 20 to accurately cut and peel off the excess part of the roof body 1 in the sunroof area 20. In this process, the fabric layer 3 is not cut. The excess part of the fabric layer 3 can be edge covered to avoid the exposure of burrs. In addition, the roof 10 has better sound and heat insulation effects and is more beautiful.
[0028] In the edge cutting operation, the excess ceiling body 1 in the skylight window area 20 can be manually cut by a wallpaper cutter, or automatically cut by a corresponding cutting device. Since the separation layer 2 is arranged between the ceiling body 1 and the fabric layer 3, the blade can cut to the separation layer 2 in the edge cutting operation, and the blade is not easy to cut to the fabric layer 3, so that the precision requirement of the blade extension length is reduced, the edge cutting operation has greater fault tolerance, the manual skill requirement of the edge cutting operation can be reduced, the risk of damage of the fabric layer 3 caused by cutting is reduced, the yield of the ceiling 10 is improved, and the edge cutting efficiency is improved, which is beneficial to improve the production rate.
[0029] In the above embodiment, the separation layer 2 is arranged between the ceiling body 1 and the fabric layer 3, so that the blade is not easy to cut to the fabric layer 3 in the edge cutting operation, the precision requirement of the blade extension length is reduced, the edge cutting operation has greater fault tolerance, the manual skill requirement of the edge cutting operation can be reduced, the edge cutting can be manually performed or automatically performed by a robot, the labor intensity of the operator is reduced, the risk of damage of the fabric layer 3 caused by cutting is reduced, the yield of the ceiling 10 is improved, the production cost is reduced, and the edge cutting efficiency is improved, so that the production rate is improved.
[0030] As some embodiments of the utility model, the ceiling body 1 can be a polyurethane composite board (PU composite board), which has good heat preservation effect, good waterproof effect, good fire resistance, no toxicity and harmlessness, and long service life, and can make the ceiling 10 have better properties.
[0031] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The separation layer 2 and the ceiling body 1 are fixedly connected.
[0032] The separation layer 2 and the ceiling body 1 can be connected by adhesion, clamping or fasteners, and the fasteners can be nails, paper clips and the like. By fixedly connecting the separation layer 2 and the ceiling body 1, the relative position of the separation layer 2 and the ceiling body 1 is fixed, so that the separation layer 2 can be arranged at the skylight window area 20 according to the preset position, the ceiling body 1 and the fabric layer 3 are separated by the separation layer 2 at the skylight window area 20, so that the blade is not easy to cut to the fabric layer 3 in the edge cutting operation, the precision requirement of the blade extension length is reduced, the risk of damage of the fabric layer 3 caused by cutting is reduced, and the yield of the ceiling 10 is improved.
[0033] In some embodiments of the utility model, the separation layer 2 and the ceiling body 1 are fixedly connected by adhesion.
[0034] The partition layer 2 and the ceiling body 1 can be adhesively connected, the partition layer 2 can be adhesively connected to the ceiling body 1 by using glue, or in the process of die forming of the ceiling 10, the ceiling body 1 can be partially melted by heating, and the melted ceiling body 1 can adhesively connect the partition layer 2 and the ceiling body 1 into an integral whole. By adhesively connecting the partition layer 2 and the ceiling body 1, the operation of fixedly connecting the partition layer 2 and the ceiling body 1 can be simplified, the production process is easy to implement, the cost is low, an additional structure for fixedly connecting the partition layer 2 and the ceiling body 1 is not needed, the production cost can be reduced, and the production efficiency is improved.
[0035] As some embodiments of the utility model, in order to make the partition layer 2 and the ceiling body 1 adhesively connect into an integral whole, the oven temperature can be increased by 10 DEG C to 20 DEG C, so that the ceiling body 1 is heated sufficiently, and the adhesion process is more smooth
[0036] In some embodiments of the utility model, as shown in Figures 1-3 The normal projection of the sunroof window area 20 is located in the partition layer 2 along the thickness direction of the ceiling 10.
[0037] The ceiling body 1, the partition layer 2 and the fabric layer 3 of the ceiling 10 are sequentially arranged along the thickness direction of the ceiling 10, and the normal projection of the sunroof window area 20 is located in the partition layer 2, that is, the area size of the partition layer 2 is greater than the area size of the sunroof window area 20, and the partition layer 2 is arranged on the sunroof window area 20, so that the blade is not easy to cut the fabric layer 3 in the cutting operation, the risk of damage of the fabric layer 3 caused by cutting is reduced, and the yield of the ceiling 10 is improved.
[0038] In some embodiments of the utility model, as shown in Figures 1-3 The interval distance between the circumferential edge of the sunroof window area 20 and the corresponding circumferential edge of the partition layer 2 is D, and the relationship 20mm≤D≤30mm is met.
[0039] The interval distance D between the circumferential edge of the sunroof window area 20 and the corresponding circumferential edge of the separation layer 2 satisfies the relationship: 20mm≤D≤30mm, and D can be 20mm, 25mm, 30mm, etc. Along the direction from the center position of the sunroof window area 20 to the edge position of the sunroof window area 20, the circumferential edge of the separation layer 2 is located outside the circumferential edge of the corresponding sunroof window area 20, so that the separation layer 2 completely covers the sunroof window area 20, so that the blade is not easy to cut the fabric layer 3 in the cutting edge operation, and the risk of cutting and damaging the fabric layer 3 is reduced, so as to improve the yield of the ceiling 10. By setting 20mm≤D≤30mm, the area size of the separation layer 2 can be reasonable, and when the excess ceiling body 1 of the sunroof window area 20 is cut and peeled off, the probability of tearing the separation layer 2 and pulling the circumferential edge of the separation layer 2 into the sunroof window area 20 can be reduced, so that the separation layer 2 can be stably fixed in the ceiling 10, and the separation layer 2 can better protect the fabric layer 3 at the sunroof window area 20, and the area size of the separation layer 2 can be reduced as much as possible to save the cost of producing the separation layer 2.
[0040] In some embodiments of the present application, as shown in Figures 1-3 The part of the fabric layer 3 and the separation layer 2 that is staggered is fixedly connected with the ceiling body 1.
[0041] The separation layer 2 is arranged to cover the sunroof window area 20, and the area of the separation layer 2 is greater than the area of the sunroof window area 20, and the area of the separation layer 2 is less than the area of the fabric layer 3, so that the separation layer 2 completely covers the sunroof window area 20, and the part of the fabric layer 3 and the separation layer 2 that is staggered is fixedly connected with the ceiling body 1, so that the separation layer 2 is covered on the sunroof window area 20 while the area of the separation layer 2 is reduced as much as possible, the contact area of the fabric layer 3 and the ceiling body 1 is increased, the connection stability of the fabric layer 3 and the ceiling body 1 is enhanced, and the connection stability of the whole ceiling 10 is enhanced, and the fabric layer 3 and the ceiling body 1 are conveniently fixedly assembled.
[0042] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The circumferential edge of the separation layer 2 is fixedly connected with the fabric layer 3.
[0043] The circumferential edge of the separation layer 2 can be fixed to the fabric layer 3, and the circumferential edge of the separation layer 2 can be connected to the fabric layer 3 by adhesive connection, clamping connection or through fasteners, which can be nails, paper clips and the like. In this way, the position of the separation layer 2 relative to the fabric layer 3 can be kept unchanged, so that the separation layer 2 can always cover the sunroof opening area 20. In the edge cutting operation, the blade can cut the separation layer 2, but it is not easy to cut the fabric layer 3, thereby reducing the risk of damage to the fabric layer 3 caused by cutting, and improving the yield of the roof 10. Moreover, in the edge cutting operation, the cut roof body 1 can be easily peeled off from the separation layer 2, and the risk of tearing the separation layer 2 and damaging the structure of the fabric layer 3 caused by the roof body 1 can be reduced, so that the edge cutting operation can be smoothly carried out, the yield of the roof 10 can be improved, and the production rate can be improved.
[0044] In some embodiments of the present application, the separation layer 2 is a non-woven fabric layer.
[0045] The non-woven fabric has the advantages of light weight, good flexibility, lightness, non-toxicity, non-odor and low price. By configuring the separation layer 2 as a non-woven fabric layer, the fabric layer 3 can be well protected, and lightweight design can be achieved. The user of the vehicle can not have adverse effects, and the production cost can be reduced.
[0046] In some embodiments of the present application, the density p of the non-woven fabric satisfies the relationship: 35g / m2≤p≤60g / m2, and p can be 35g / m2, 45g / m2, 55g / m2, 60g / m2, etc. The non-woven fabric can be selected from spunlace non-woven fabric, silicone non-woven fabric, hot-rolled non-woven fabric, etc. In this way, the weight, toughness and structural strength of the separation layer 2 can meet the standard, so that the separation layer 2 can achieve the effect of protecting the fabric layer 3, reduce the risk of damage to the fabric layer 3 caused by cutting, and improve the yield of the roof 10. Moreover, the separation layer 2 with good toughness can avoid the risk of peeling off the sponge layer in the fabric layer 3 when the roof body 1 is peeled off in the edge cutting operation, thereby avoiding the quality problem of unevenness after subsequent edge covering.
[0047] According to the vehicle of the present application, the roof 10 of the vehicle is provided with the separation layer 2 between the roof body 1 and the fabric layer 3. In the edge cutting operation, the blade is not easy to cut the fabric layer 3, which can reduce the precision requirement for the extension length of the blade, so that the edge cutting operation has greater fault tolerance, thereby reducing the requirement for the skill of the edge cutting operation, and the edge cutting operation can be carried out manually or automatically by a robot, which can reduce the labor intensity of the operator, reduce the risk of damage to the fabric layer 3 caused by cutting, improve the yield of the roof 10, reduce the production cost, and improve the edge cutting efficiency and the production rate.
