Description

Technical Field

[0001] This utility model relates to a sunroof for vehicles and a sunroof guide rail, and more specifically, it relates to a sunroof guide rail for passenger vehicles and a sunroof for passenger vehicles having the guide rail. Background Technology

[0002] Some existing passenger vehicles have sunroofs on the roof, which allow users to observe the top of the vehicle and provide a better experience. In order to provide sun protection, sunshade curtains are also installed on the sunroof to block sunlight. For the storage and opening of the sunshade curtains, a guide rail design is usually used to make the sunshade curtains easy to open and close. However, the existing sunroof guide rails are not only complex in structure, but also have a large longitudinal dimension, which takes up a lot of space in the vehicle. In addition, they make the entire sunroof structure more complicated and heavy, which can make users feel claustrophobic.

[0003] For example, Chinese Patent Publication No. CN210211997U, published on March 31, 2020, is entitled "A Car Sunroof Guide Rail," which includes a sunshade installation part and a mechanical assembly installation part. The sunshade installation part includes a plastic guide rail installation groove and a sunshade chain hole that communicates with the plastic guide rail installation groove through the sunshade installation groove. The plastic guide rail installation groove is formed by an outer guide rail plate, an upper guide rail plate, an inner guide rail plate, and a lower guide rail plate. The length of the outer guide rail plate is shorter than that of the inner guide rail plate, and the length of the upper guide rail plate is longer than that of the lower guide rail plate. The sunshade installation groove is formed by an outer curtain groove plate, a bottom curtain groove plate, and an inner curtain groove plate. The sunshade chain hole is formed by a chamfered groove plate, with one side of the chamfered groove plate connected to the extension plate of the lower guide rail groove plate, and the other side of the chamfered groove plate connected to the inner curtain groove plate. The advantage of this solution is that it integrates the mechanical assembly and the sunshade carrier into a single guide rail component, reducing the overall structural complexity of the sunroof, minimizing the risk of failure in the sunroof's operating unit, and improving reliability. However, the guide rail's structure is relatively complex, with multiple grooves along its longitudinal direction, increasing its longitudinal dimensions and occupying a significant amount of interior space. Utility Model Content

[0004] This invention overcomes the problems of existing sunroof guide rails and complex sunroof structures, and provides a sunroof guide rail for passenger vehicles and a sunroof for passenger vehicles with the guide rail. In this solution, the sunroof guide rail structure is simplified and the longitudinal dimension is reduced, the sunroof structure is simpler, and the overall performance of the vehicle can be improved.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a sunroof guide rail for passenger vehicles, including a guide rail body, a sliding groove on the guide rail body facing the middle of the passenger vehicle, and a fixing part on the side of the guide rail body away from the sliding groove. The opening direction of the sliding groove is the same as the fixing position of the fixing part and both face the roof of the passenger vehicle. The bottom position of the sliding groove is not lower than the bottom position of the fixing part. In this solution, both the sliding groove and the fixing part are set on the guide rail body, and the opening of the sliding groove and the fixing position of the fixing part are arranged facing the roof of the vehicle. This allows the sunroof to be closer to the bottom of the passenger vehicle, and the bottom of the sliding groove and the fixing part are basically on the same straight line, which can effectively reduce the longitudinal dimension of the guide rail body and the sunroof as a whole. In addition, the structural arrangement direction on the guide rail is all along the horizontal position, which not only reduces the longitudinal dimension but also simplifies the structure of the guide rail.

[0006] Preferably, the chute includes a support portion and a limiting portion located above the support portion. The width of the support portion is greater than the width of the limiting portion, and the support portion and the limiting portion are parallel. The support portion is provided with a hook portion, which forms a chute opening with the limiting portion. The support portion mainly supports the sunshade, while the limiting portion restricts the longitudinal displacement and movement of the sunshade on the chute. Ensuring that the support portion and the limiting portion are arranged in parallel can reduce the longitudinal dimension of the chute. Then, the hook portion is used to hook the sunshade, preventing it from detaching from the chute.

[0007] Preferably, a first receiving groove is provided between the slide groove and the fixing part. The first receiving groove includes a first groove body and a second groove body. The first groove body is cylindrical, and the second groove body is radially connected to the first groove body and inclined towards the top of the limiting part. The first receiving groove can accommodate a structure for limiting the position of the roller blind, which has a limiting effect on the roller blind arranged in the slide groove, and also reduces the weight of the guide rail body to a certain extent.

[0008] Preferably, the fixing part includes a fixing groove near the slide groove and a fixing plate away from the slide groove. The fixing groove and the fixing plate are inclined in opposite directions, with the fixing groove inclined towards the slide groove. The fixing groove and the fixing plate serve as mounting parts for the guide rail body, allowing the guide rail body to be installed at the bottom of the sunroof. The opposite inclination directions of the fixing groove and the fixing plate ensure the clamping effect of the fixing components on both, improving the fixing strength.

[0009] Preferably, a second receiving groove is provided between the fixing groove and the fixing plate, with the second receiving groove facing away from the roof of the passenger vehicle. The second receiving groove can reduce the mass of the guide rail body to a certain extent, and at the same time, it can accommodate some wiring harnesses on the sunroof and some structural components, thus improving the aesthetics of the sunroof interior.

[0010] Preferably, the fixing part further includes a limiting groove disposed between the fixing groove and the fixing plate, the limiting groove being located on the opposite side of the second receiving groove. The limiting groove, arranged between the fixing groove and the fixing plate, reduces the material used in the guide rail body, thereby reducing the overall weight of the guide rail body. Simultaneously, the limiting groove improves the installation stability of the guide rail body, ensuring its fixed position.

[0011] A sunroof for passenger vehicles includes a sunroof guide rail as described above, and a glass assembly. Two sets of guide rail bodies are fixed parallel to each other at the bottom of the glass assembly. The guide rail bodies have opposing grooves, and a sunroof curtain is slidably connected within each groove. The guide rail bodies are located below the glass assembly, i.e., inside the vehicle. The opposing grooves ensure that the sunroof curtain is installed within the grooves on the guide rail bodies on both sides, allowing the sunroof curtain to slide within the grooves.

[0012] Preferably, the guide rail body and the glass assembly are connected by a fastener, which includes a first fixing part and a second fixing part. The first fixing part is embedded in the fixing groove, and the second fixing part abuts against the side of the fixing plate away from the fixing groove. The first and second fixing parts are used to fix the guide rail body. Since the fixing groove and the fixing plate are arranged at an angle, the first and second fixing parts have a clamping effect on them, thereby clamping the guide rail body and achieving a stable connection.

[0013] Preferably, the fixing member is further provided with a top block, which is located between the first fixing part and the second fixing part, and abuts against the limiting groove. The top block can abut against the limiting groove at the top of the guide rail body to generate a certain clamping force, which, together with the first fixing part and the second fixing part, makes the guide rail arrangement more stable.

[0014] Preferably, the glass assembly is also equipped with a drive device and a roller blind lock, the roller blind lock being connected to the sunshade. The drive device enables electrically controlled extension and retraction of the roller blind lock, eliminating the need for manual control and providing convenience and labor-saving benefits.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) The sunroof guide rail structure is simplified and the longitudinal dimension is reduced, the sunroof structure is simpler, and the overall performance of the vehicle can be improved; (2) The guide rail body has the advantage of weight tilting, which ensures the light load on the top of the vehicle and improves the safety of the sunroof guide rail; (3) Automated control reduces the consumption of manpower and makes it more convenient for users to use the sunroof of passenger cars.

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Example 1: As Figure 1 The sunroof guide rail shown includes a guide rail body 1. The guide rail body 1 is generally elongated and its length is along the front-rear or left-right direction of the vehicle. The guide rail body 1 is also curved to adapt to the arc structure of the vehicle roof. A sliding groove 2 and a fixing part 3 for fixing the guide rail body 1 to the roof are provided on the guide rail body 1. The sliding groove 2 and the fixing part 3 are integral with the guide rail body 1 and can be made of plastic, which can greatly reduce the weight of the guide rail body 1 and achieve the effect of reducing the load on the vehicle roof. The sliding groove 2 is located on the side facing the middle of the vehicle, while the fixing part 3 is located on the side away from the middle of the vehicle. In this way, after the guide rail body 1 is fixed, the sunroof in the middle of the vehicle roof can be arranged on the sliding groove 2. The position of the sliding groove 2 and the position of the fixing part 3 are flush and both are located on the top of the guide rail body 1, that is, on the side of the guide rail body 1 closer to the vehicle roof. On the one hand, the fixing part 3 can be directly fixed to the sunroof. On the other hand, the position of the sliding groove 2 is closer to the vehicle roof, reducing the longitudinal dimension of the guide rail body 1.

[0024] Specifically, the slide 2 includes a support part 4 and a limiting part 5. The limiting part 5 is located above the support part 4, and the support part 4 and the limiting part 5 are in a relatively parallel state. The support part 4 and the limiting part 5 are arranged along the length direction of the guide rail body 1 and are consistent with the length of the guide rail body 1, thereby ensuring the effective travel of the roller blind and realizing the raising and lowering of the roller blind. Figure 1 As shown, the limiting part 5 has a relatively straight structure in the horizontal direction, while the supporting part 4 consists of two parts in the horizontal direction, including a first supporting part 4.1 and a second supporting part 4.2. The position of the first supporting part 4.1 is slightly higher than that of the second supporting part 4.2, and the first supporting part 4.1 is closer to the fixing part 3, that is, located inside the slide 2. The first supporting part 4.1 and the second supporting part 4.2 are connected together by a sloping step. A hook part 6 is provided on the side of the second supporting part 4.2 away from the first supporting part 4.1. The hook part 6 bends upward toward the position of the limiting part 5. The sum of the horizontal lengths of the first supporting part 4.1 and the sloping step is close to the horizontal length of the limiting part 5, that is, the second supporting part 4.2 is located outside the limiting part 5. Therefore, the overall horizontal dimension of the supporting part 4 is larger than the horizontal dimension of the limiting part 5, so that the interior of the slide 2 becomes horizontal, and a vertical slide groove opening 7 is formed between the hook part 6 and the limiting part 5. The horizontal structure inside the slide 2 can accommodate more of the sunshade, increase the connection with the sunshade, and improve the connection strength. The slide chute opening 7 and hook 6 can restrict and fix the sunshade, preventing the sunshade from detaching laterally from the slide chute, so that the sunshade can slide stably on the guide rail body 1.

[0025] On the other hand, the fixing part 3 is located on the side of the guide rail body 1 away from the slide groove 2, that is, the fixing part 3 is located on the side away from the middle of the vehicle. Similarly, the fixing part 3 is provided on the upper side of the guide rail body 1. Specifically, the fixing part 3 includes a fixing groove 11 and a fixing plate 12. The length direction of the fixing groove 11 and the fixing plate 12 is the same as the length direction of the guide rail body 1. The fixing groove 11 is arranged at the middle position in the length direction of the guide rail body 1, while the fixing plate 12 is arranged on the side of the guide rail body 1 away from the slide groove 2. Both the fixing plate 12 and the fixing groove 11 are arranged at a certain inclination. Figure 1 As shown, the inclined direction of the fixed groove 11 is towards the side where the slide 2 is located, while the inclined direction of the fixed plate 12 is away from the side where the slide 2 is located. Thus, the fixed groove 11 and the fixed plate 12 form a structure with a larger upper distance and a smaller lower distance. When the fixed structure and the fixed part 3 are used together, it is only necessary to make the distance between the fixed structures less than the maximum distance between the fixed groove 11 and the fixed plate 12, so as to achieve the clamping of the fixed part 3 and finally achieve the fixation of the guide rail body 1.

[0026] Specifically, a groove is provided on the outer side of the fixing plate 12 (the side away from the fixing groove 11). The groove allows the fixing structure to better clamp the fixing part 3, preventing the outer side of the fixing plate 12 from slipping due to being too smooth.

[0027] A first receiving groove 8 is also provided between the slide groove 2 and the fixing part 3. The first receiving groove 8 is located in the middle of the guide rail body 1 and is close to the fixing groove 11. The first receiving groove 8 and the fixing groove 11 share a groove wall. The first receiving groove 8 includes a first groove 9 and a second groove 10. The first groove 9 is a cylindrical groove and is located inside the guide rail body 1. One side of the second groove 10 is connected to the first groove 9, and the other side of the second groove 10 extends to the top of the guide rail body 1 and is arranged at an angle above the limiting part 5, forming the opening of the first receiving groove 8. The radial opening size of the first groove 9 is less than half the circle of the first groove 9, which can play a role in limiting and fixing the structure located in the first groove 9.

[0028] A limiting groove 14 and a second receiving groove 13 are also provided at the position of the fixing part 3. The limiting groove 14 and the second receiving groove 13 are located on the upper and lower sides of the guide rail body 1, respectively, that is, the back of the second receiving groove 13 is the limiting groove 14. The second receiving groove 13 is a cylindrical groove with the groove opening facing downwards, and the groove opening of the limiting groove 14 faces upwards. Both the second receiving groove 13 and the limiting groove 14 can significantly reduce the overall weight of the guide rail body 1. In addition, the groove opening size of the second receiving groove 13 is also smaller than half the arc length of the circle of the second receiving groove 13. This can limit the cylindrical structure arranged in the second receiving groove 13. The second receiving groove 13 can also store some wire harnesses on the skylight, which can achieve an aesthetic effect. The limiting groove 14 is formed by hollowing out between the fixing groove 11 and the fixing plate 12. It is mainly used to cooperate with the fixing parts to achieve the overall fixation of the guide rail body 1.

[0029] Example 2: As Figures 2 to 5The illustrated sunroof for a passenger vehicle includes the sunroof guide rails as shown in Embodiment 1, and also includes a glass assembly 15. The glass assembly 15 includes a base plate, a glass plate, a rubber sealing ring, and other structures, forming a thin plate-like structure, and is installed at the top of the passenger vehicle to form a sunroof. Two sets of guide rail bodies 1 are arranged parallel to each other at the bottom of the glass assembly 15, that is, inside the passenger vehicle. In this embodiment, taking the length direction of the guide rail body 1 along the front-rear direction of the passenger vehicle as an example, the two sets of guide rail bodies 1 are symmetrically arranged below the glass assembly 15. Below the glass assembly 15 and between the two sets of guide rail bodies 1, a roller blind 16 is also arranged. The two sides of the roller blind 16 in the width direction are arranged inside the slide grooves 2 of the two sets of guide rail bodies 1, and one end of the roller blind 16 in the length direction is arranged on one side of the glass assembly 15 in the length direction. Specifically, a roller 23 and a limiter 24 are provided on one side of the glass assembly 15. The roller blind 16 can be rolled up in the roller 23. The limiter 24 maintains a certain gap with the glass assembly 15, so that the roller blind 16 can pass through the gap between the limiter 24 and the glass assembly 15. The limiter 24 not only limits the bottom of the roller blind 16, but also guides the roller blind 16.

[0030] A fixing member 17 is also provided between the guide rail body 1 and the glass assembly 15. Several fixing members 17 are provided and evenly spaced along the length of the glass assembly 15. The fixing members 17 can engage with the fixing groove 11 and fixing plate 12 on the guide rail body 1. Specifically, for example... Figure 5 As shown, the fastener 17 includes a first fixing part 18 and a second fixing part 19. The first fixing part 18 and the second fixing part 19 are located below the fastener 17. The upper part of the fastener 17 is fixedly connected to the glass assembly 15. The ends of the first fixing part 18 and the second fixing part 19 are inclined towards each other to form a constricted shape. The first fixing part 18 is located on the right side, and the second fixing part 19 is located on the left side (as shown in the figure). Thus, the first fixing part 18 is embedded in the fixing groove 11. Since the fixing groove 11 is inclined, the inclination direction of the first fixing part 18 is the same as the inclination direction of the fixing groove 11. Similarly, the second fixing part 19 is tilted in the opposite direction to the first fixing part 18, and abuts against the groove on the side of the fixing plate 12 away from the fixing groove 11. Since the fixing groove 11 and the fixing plate 12 are generally larger at the top and smaller at the bottom, and the first fixing part 18 and the second fixing part 19 are also generally larger at the top and smaller at the bottom, the lower part of the fixing member 17 can clamp the upper part of the fixing part 3. The fixing plate 12 has a certain degree of flexibility and can undergo slight deformation to ensure that the force between the second fixing part 19 and the fixing plate 12 is large enough to improve the clamping effect.

[0031] In addition, a top block 20 is provided in the middle of the fixing part 17. The top block 20 is located in the middle of the first fixing part 18 and the second fixing part 19. The top block 20 is pressed against the limiting groove 11 of the guide rail body 1. The top block 20 can generate a certain downward force on the guide rail body 1, and the first fixing part 18 and the second fixing part 19 can generate an upward force on the guide rail body 1, thereby making the fixing of the guide rail body 1 more stable and preventing it from undergoing lateral and longitudinal displacement.

[0032] like Figure 4 As shown, a reinforcing member 25 is also provided in the first receiving groove 8 of the guide rail body 1. The reinforcing member 25 is embedded in the first receiving groove 8 and extends all the way to the top of the limiting part 5 and the top of the roller blind 16. It can limit the roller blind 16 from the top and also strengthen the structure of the guide rail body 1. The conduit 26 can be arranged in the second receiving groove 13 for placing wire harnesses and other structures.

[0033] Example 3: As Figures 2 to 5 The illustrated sunroof for a passenger vehicle includes the sunroof guide rails as shown in Embodiment 1, and also includes a glass assembly 15. The glass assembly 15 includes a base plate, a glass plate, a rubber sealing ring, and other structures, forming a thin plate-like structure, and is installed at the top of the passenger vehicle to form a sunroof. Two sets of guide rail bodies 1 are arranged parallel to each other at the bottom of the glass assembly 15, that is, inside the passenger vehicle. In this embodiment, taking the length direction of the guide rail body 1 along the front-rear direction of the passenger vehicle as an example, the two sets of guide rail bodies 1 are symmetrically arranged below the glass assembly 15. Below the glass assembly 15 and between the two sets of guide rail bodies 1, a roller blind 16 is also arranged. The two sides of the roller blind 16 in the width direction are arranged inside the slide grooves 2 of the two sets of guide rail bodies 1, and one end of the roller blind 16 in the length direction is arranged on one side of the glass assembly 15 in the length direction. Specifically, a roller 23 and a limiter 24 are provided on one side of the glass assembly 15. The roller blind 16 can be rolled up in the roller 23. The limiter 24 maintains a certain gap with the glass assembly 15, so that the roller blind 16 can pass through the gap between the limiter 24 and the glass assembly 15. The limiter 24 not only limits the bottom of the roller blind 16, but also guides the roller blind 16.

[0034] A fixing member 17 is also provided between the guide rail body 1 and the glass assembly 15. Several fixing members 17 are provided and evenly spaced along the length of the glass assembly 15. The fixing members 17 can engage with the fixing groove 11 and fixing plate 12 on the guide rail body 1. Specifically, for example... Figure 5As shown, the fastener 17 includes a first fixing part 18 and a second fixing part 19. The first fixing part 18 and the second fixing part 19 are located below the fastener 17. The upper part of the fastener 17 is fixedly connected to the glass assembly 15. The ends of the first fixing part 18 and the second fixing part 19 are inclined towards each other to form a constricted shape. The first fixing part 18 is located on the right side, and the second fixing part 19 is located on the left side (as shown in the figure). Thus, the first fixing part 18 is embedded in the fixing groove 11. Since the fixing groove 11 is inclined, the inclination direction of the first fixing part 18 is the same as the inclination direction of the fixing groove 11. Similarly, the second fixing part 19 is tilted in the opposite direction to the first fixing part 18, and abuts against the groove on the side of the fixing plate 12 away from the fixing groove 11. Since the fixing groove 11 and the fixing plate 12 are generally larger at the top and smaller at the bottom, and the first fixing part 18 and the second fixing part 19 are also generally larger at the top and smaller at the bottom, the lower part of the fixing member 17 can clamp the upper part of the fixing part 3. The fixing plate 12 has a certain degree of flexibility and can undergo slight deformation to ensure that the force between the second fixing part 19 and the fixing plate 12 is large enough to improve the clamping effect.

[0035] In addition, a top block 20 is provided in the middle of the fixing part 17. The top block 20 is located in the middle of the first fixing part 18 and the second fixing part 19. The top block 20 is pressed against the limiting groove 11 of the guide rail body 1. The top block 20 can generate a certain downward force on the guide rail body 1, and the first fixing part 18 and the second fixing part 19 can generate an upward force on the guide rail body 1, thereby making the fixing of the guide rail body 1 more stable and preventing it from undergoing lateral and longitudinal displacement.

[0036] like Figure 4 As shown, a reinforcing member 25 is also provided in the first receiving groove 8 of the guide rail body 1. The reinforcing member 25 is embedded in the first receiving groove 8 and extends all the way to the top of the limiting part 5 and the top of the roller blind 16. It can limit the roller blind 16 from the top and also strengthen the structure of the guide rail body 1. The conduit 26 can be arranged in the second receiving groove 13 for placing wire harnesses and other structures.

[0037] A drive unit 21 and a roller blind lock 22 are also provided on the glass assembly 15. The drive unit 21 is located near the roller drum 23, while the roller blind lock 22 is located at the positions of the guide rail bodies 1 on both sides. The roller blind lock 22 can drive and lock the roller blind 16 on the glass assembly 15, and the drive unit 21 drives the roller blind lock 22 to move, thereby controlling the roller blind 16. The roller blind 16 is extended and retracted by electric control of the roller blind lock 22, avoiding manual control and saving labor.
