Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle seat mounting assembly and a vehicle. Background Technology

[0002] In the prior art, the waterproof sealing of vehicle seat mounting assemblies is poor. Utility Model Content

[0003] In view of this, this application provides a seat mounting assembly for a vehicle and a vehicle to improve the problem of poor waterproof sealing.

[0004] In a first aspect, this application provides a seat mounting assembly, which includes a seat mounting frame, a seat base plate, a first annular seal, and a second annular seal. The seat mounting frame includes a first annular pressed portion and a second annular pressed portion. The projection range of the first annular pressed portion along the height direction is projection range T1, and the projection range of the second annular pressed portion along the height direction is projection range T2. Projection range T2 surrounds projection range T1, and the position height of the second annular pressed portion is greater than the position height of the first annular pressed portion. The first annular seal is pressed by the seat base plate above the first annular pressed portion, and the second annular seal is pressed by the seat base plate above the second annular pressed portion.

[0005] In this application, the seat mounting assembly includes at least two annular sealing structures. The first annular sealing structure includes a seat base plate, a first annular seal, and a first annular pressed portion. The second annular sealing structure includes a seat base plate, a second annular seal, and a second annular pressed portion. Even if water located below the seat mounting frame (water encountered by the vehicle in a wading environment) tends to enter the vehicle's passenger compartment after passing through an opening, both the first and second annular sealing structures can prevent water from entering the passenger compartment. Even if some parts of the first annular sealing structure have weaker sealing properties, allowing some water to pass through, this water is less likely to pass through the second annular sealing structure and enter the passenger compartment. Under gravity, water generally flows along the upper surface of the seat mounting frame. Because the height of the second annular pressed portion is greater than that of the first annular pressed portion, this height difference makes it difficult for water to flow from the relatively lower first annular pressed portion to the relatively higher second annular pressed portion by overcoming gravity. Therefore, in this application, the seat mounting assembly has good waterproof sealing performance.

[0006] Optionally, a set height distance H is provided between the first annular pressed part and the second annular pressed part, satisfying 30mm≤H≤50mm.

[0007] Optionally, the seat mounting frame includes a first annular step portion, and the first annular pressed portion is connected to the second annular pressed portion through the first annular step portion; the first annular step portion includes a water-blocking wall, and the water-blocking wall has a set included angle α with the height direction, satisfying 0°≤|α|≤10°.

[0008] Optionally, the first annular step portion further includes a first bent section, the height of which is greater than the height of the water-retaining wall, and at least a portion of the structure of the first bent section is in contact with the seat base.

[0009] Optionally, the first annular pressed portion and the second annular pressed portion have a set horizontal distance W, which satisfies 20mm≤W≤30mm.

[0010] Optionally, the seat base includes a first annular pressing portion and a second annular pressing portion, the position height of the second annular pressing portion being greater than the position height of the first annular pressing portion; the first annular seal is pressed by the first annular pressing portion above the first annular pressed portion, and the second annular seal is pressed by the second annular pressing portion above the second annular pressed portion.

[0011] Optionally, the seat base includes a second annular step portion, and the first annular pressing portion is connected to the second annular pressing portion through the second annular step portion.

[0012] Optionally, the seat base includes an edge structure, the edge structure including a second annular pressing portion.

[0013] Optionally, the seat base includes a pressure-receiving portion, and the distance between the first annular pressing portion and the pressure-receiving portion is smaller than the distance between the second annular pressing portion and the pressure-receiving portion.

[0014] Secondly, this application provides a vehicle that includes the seat mounting assembly described above. Accordingly, the vehicle of this application also includes the technical effects described above, which will not be repeated here.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0064] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0065] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0066] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0067] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0068] In the accompanying diagram, directions X, Y, and Z are perpendicular to each other. Direction Y represents the direction from the front of the vehicle to the rear, direction Z represents the height direction (from the top of the vehicle to the bottom of the vehicle), and direction I represents the direction of water flow.

[0069] In a first aspect, embodiments of this application provide a vehicle seat mounting assembly for mounting on the front floor of the vehicle. The seat mounting assembly is used to carry the front seat assembly of the vehicle. The front seat assembly may include a driver's seat assembly and a passenger seat assembly, each of which includes a seat body and a seat mounting bracket.

[0070] Please refer to Figure 1 As shown, the seat mounting bracket 202 is mounted above the seat mounting assembly 10, and the seat body 201 is mounted above the seat mounting bracket 202. The seat body 201 can slide relative to the seat mounting bracket 202 and is used to carry the driver or passenger.

[0071] Please refer to Figure 2 As shown, the seat mounting assembly 10 includes a seat mounting frame 1 and a seat base plate 2. Please refer to... Figure 3 As shown, the seat mounting frame 1 is used for mounting on the front floor of the vehicle (not shown in the figure). The seat mounting frame 1 is provided with an opening 1a, which is used to avoid obstructing the vehicle's main components (including the engine assembly, air filter, and battery). The seat base plate 2 is located above the seat mounting frame 1 and covers the opening 1a.

[0072] Please refer to Figure 1As shown, the seat mounting bracket 202 can be securely connected to the seat mounting frame 1 using fasteners (e.g., bolts). During the installation of the seat mounting bracket 202 to the seat mounting frame 1, the seat mounting bracket 202 is first pressed against the seat base plate 2, applying downward pressure to the seat base plate 2 to press it firmly against the seat mounting frame 1. After the seat mounting bracket 202 is securely connected to the seat mounting frame 1, both the pressure exerted by the seat mounting bracket 202 on the seat base plate 2 and the pressure exerted by the seat base plate 2 on the seat mounting frame 1 are maintained.

[0073] Please refer to Figure 4 As shown, the seat mounting frame 1 includes a first annular pressing portion 11 and a second annular pressing portion 12. Please refer to... Figure 5 As shown, the projection range of the first annular pressed portion 11 along the height direction (parallel to direction Z) is projection range T1, and the projection range of the second annular pressed portion 12 along the height direction is projection range T2. Projection range T2 surrounds projection range T1. Please refer to... Figure 6 As shown, the position height of the second annular pressed part 12 is greater than the position height of the first annular pressed part 11.

[0074] Please refer to Figure 3 As shown, the seat mounting assembly 10 includes a first annular seal 3 and a second annular seal 4. Please refer to... Figure 4 As shown, the first annular seal 3 is pressed by the seat base plate 2 above the first annular pressed portion 11, and the second annular seal 4 is pressed by the seat base plate 2 above the second annular pressed portion 12.

[0075] Based on the above, it can be inferred that in some embodiments of this application, the seat mounting assembly 10 includes at least two annular sealing structures. The first annular sealing structure includes a seat base plate 2, a first annular seal 3, and a first annular pressed portion 11. The second annular sealing structure includes a seat base plate 2, a second annular seal 4, and a second annular pressed portion 12. Even if water located below the seat mounting frame 1 (water encountered by the vehicle in a wading environment) tends to enter the vehicle's passenger compartment after passing through the opening 1a, both the first and second annular sealing structures can be used to prevent water from entering the vehicle's passenger compartment. Even if the sealing performance of some parts of the first annular sealing structure is weak, and some water can pass through the first annular sealing structure, this water that has passed through the first annular sealing structure is unlikely to pass through the second annular sealing structure and enter the vehicle's passenger compartment. Under the influence of gravity, water generally flows along the upper surface of the seat mounting frame 1. Since the height of the second annular pressed portion 12 is greater than the height of the first annular pressed portion 11, this height difference makes it difficult for water to flow from the relatively lower first annular pressed portion 11 to the relatively higher second annular pressed portion 12 by overcoming gravity. Therefore, in some embodiments of this application, the seat mounting assembly 10 has good waterproof sealing performance.

[0076] Furthermore, using a single seal for support can easily lead to a large load on that single seal and a high degree of stress concentration within it. In some embodiments of this application, the seat mounting frame 1 supports the seat base 2 via a first annular seal 3 and a second annular seal 4. The load borne by each of the first annular seal 3 and the second annular seal 4 is relatively small, and the degree of stress concentration within each is relatively small. Therefore, the service life of both the first annular seal 3 and the second annular seal 4 is relatively long.

[0077] Alternatively, please refer to Figure 6 As shown, there is a set height distance H between the first annular pressed part 11 and the second annular pressed part 12, satisfying 30mm≤H≤50mm. The height distance H can specifically be 30mm, 35mm, 40mm, 45mm or 50mm.

[0078] If the height distance H is less than 30mm, the water needs to climb a relatively small distance, requiring less kinetic energy, and the water can easily flow from the relatively lower first annular pressed part 11 to the relatively higher second annular pressed part 12. If the height distance H is greater than 50mm, the first annular pressed part 11 is too low, which can easily cause interference between the first annular pressed part 11 and the assembly (not shown in the figure). Therefore, a height distance H within the range of 30mm to 50mm is preferable.

[0079] Alternatively, please refer to Figure 6 As shown, the seat mounting frame 1 includes a first annular stepped portion 13, and a first annular pressed portion 11 is connected to a second annular pressed portion 12 via the first annular stepped portion 13. The first annular stepped portion 13 includes a water-retaining wall 131, which has a set angle α with the height direction (the direction parallel to direction Z), satisfying 0°≤|α|≤10°. The absolute value of the angle α can be equal to 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, or 10°. With this configuration, the water-retaining effect of the water-retaining wall 131 is better, and water is less likely to flow from the relatively lower first annular pressed portion 11 to the relatively higher second annular pressed portion 12.

[0080] If the included angle α equals 0°, please refer to... Figure 7 As shown, the water-retaining wall 131 extends along the height direction. If |α| is greater than 0° and |α| is less than or equal to 10°, then the extension direction of the water-retaining wall 131 is as follows. Figure 8 or Figure 9 As shown.

[0081] In addition, such as Figure 6 The first annular stepped portion 13 shown has good bending resistance, so that the structure between the first annular pressed portion 11 and the second annular pressed portion 12 can better resist bending moments about the X direction or about the Y direction.

[0082] Alternatively, please refer to Figure 6 As shown, the first annular step portion 13 also includes a first bent section 132. The position height of the first bent section 132 is greater than the position height of the water-blocking wall 131. At least a portion of the structure of the first bent section 132 can fit against the seat base plate 2. This arrangement can also form a baffle structure to reduce the possibility of water flowing from the relatively lower first annular pressed portion 11 to the relatively higher second annular pressed portion 12.

[0083] The first annular step portion 13 also includes a second bent section 133, the position height of which is less than the position height of the water-retaining wall 131.

[0084] In other embodiments, please refer to Figure 10As shown, the seat mounting frame 1 may also include a water-retaining groove 14, which may be located below the water-retaining wall 131. The concave direction of the water-retaining groove 14 is perpendicular to the height direction, and the concave direction of the water-retaining groove 14 is away from the first annular pressed portion 11. The opening of the water-retaining groove 14 faces the first annular pressed portion 11. Even if some water flows from the first annular pressed portion 11 to the water-retaining wall 131, the water first enters the water-retaining groove 14 to consume its kinetic energy. The water that enters the water-retaining groove 14 first is rebounded by the water-retaining groove 14 and moves out of the water-retaining groove 14. The water moving out of the water-retaining groove 14 consumes the kinetic energy of the water that enters the water-retaining groove 14 later. Therefore, the water-retaining groove 14 can reduce the possibility of water overflowing the water-retaining wall 131.

[0085] In other embodiments, referring to Figure 11, the seat mounting frame 1 may further include a water-retaining rib 15. The water-retaining rib 15 may be located below the water-retaining wall 131 and above the water-retaining groove 14. The protrusion direction of the water-retaining rib 15 is perpendicular to the height direction and faces the first annular pressed portion 11. The water-retaining rib 15 can dissipate the kinetic energy of the water, thereby reducing the possibility of water overflowing the water-retaining wall 131.

[0086] In other embodiments, please refer to Figure 12 As shown, the seat mounting frame 1 may include an annular ramp 16, and the first annular pressed portion 11 is connected to the second annular pressed portion 12 via the annular ramp 16. In this configuration, the annular ramp 16 can also be used to dissipate the kinetic energy of water to reduce the possibility of water flowing from the relatively lower first annular pressed portion 11 to the relatively higher second annular pressed portion 12.

[0087] Alternatively, please refer to Figure 6 As shown, the first annular pressed portion 11 and the second annular pressed portion 12 have a set horizontal interval W, which satisfies 20mm≤W≤30mm. The horizontal interval W can specifically be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm or 30mm.

[0088] If the horizontal spacing W is less than 20 mm, the water can easily flow from the first annular pressed part 11 to the second annular pressed part 12 after consuming less kinetic energy. If the horizontal spacing W is greater than 30 mm, the water can easily interfere with the first annular pressed part 11 and the assembly (not shown in the figure). Therefore, a horizontal spacing W within the range of 20 mm to 30 mm is preferable.

[0089] Alternatively, please refer to Figure 4As shown, the seat base 2 includes a first annular pressing portion 21 and a second annular pressing portion 22. The height of the second annular pressing portion 22 is greater than the height of the first annular pressing portion 21. The first annular seal 3 is pressed by the first annular pressing portion 21 above the first annular pressed portion 11, and the second annular seal 4 is pressed by the second annular pressing portion 22 above the second annular pressed portion 12. In this configuration, each annular pressing portion of the seat base 2 can be relatively close to its corresponding pressed portion in the height direction. The first annular pressing portion 21 is relatively close to the first annular pressed portion 11 in the height direction, so that the first annular pressing portion 21 can reliably press the first annular seal 3 against the first annular pressed portion 11. The second annular pressing portion 22 is relatively close to the second annular pressed portion 12 in the height direction, so that the second annular pressing portion 22 can reliably press the second annular seal 4 against the second annular pressed portion 12. Therefore, in some embodiments of this application, the seat mounting assembly 10 has good waterproof sealing performance.

[0090] Alternatively, please refer to Figure 13 As shown, the seat base plate 2 includes a second annular step portion 23, and the first annular pressing portion 21 is connected to the second annular pressing portion 22 through the second annular step portion 23. The first annular step portion 13 has good bending resistance, so that the structure between the first annular pressing portion 21 and the second annular pressing portion 22 can better resist bending moments about the X direction or about the Y direction.

[0091] Alternatively, please refer to Figure 13 As shown, the seat base 2 includes an edge structure 24, which includes a second annular pressing portion 22. Correspondingly, a first annular pressing portion 21 is located on the non-edge structure of the seat base 2.

[0092] Among them, the edge structure 24 can also be a flange structure 24a, which is flanged downward relative to the main structure of the seat base plate 2.

[0093] Alternatively, please refer to Figure 13 As shown, the seat base 2 includes a pressure-receiving portion 25, and the distance between the first annular pressing portion 21 and the pressure-receiving portion 25 is smaller than the distance between the second annular pressing portion 22 and the pressure-receiving portion 25. In this configuration, the pressure borne by the first annular pressing portion 21 from the pressure-receiving portion 25 is greater than the pressure borne by the second annular pressing portion 22 from the pressure-receiving portion 25. Consequently, the first annular pressing portion 21 can more reliably press the first annular seal 3 against the first annular pressed portion 11, making it less likely for water to pass through the first sealing structure.

[0094] At least a portion of the projection range of the pressure-bearing portion 25 in the height direction is located within the projection range of the first annular pressing portion 21 in the height direction.

[0095] In addition, the pressure borne by the pressure-bearing part 25 comes from the seat base plate 2.

[0096] In other embodiments, the projection range of the first annular pressing portion 21 in the height direction is located between the projection range of the pressed portion 25 in the height direction and the projection range of the second annular pressing portion 22 in the height direction. In other words, the projection range of the first annular pressing portion 21 in the height direction surrounds the projection range of the pressed portion 25 in the height direction.

[0097] In some embodiments, from a perspective along the height direction, the first annular pressed portion 11, the second annular pressed portion 12, the first annular stepped portion 13, the water-retaining groove 14, the water-retaining rib 15, and the annular ramp 16 mentioned above are all annular structures surrounding the opening 1a. Correspondingly, from a perspective along the height direction, the first annular pressed portion 21, the second annular pressed portion 22, the second annular stepped portion 23, and the edge structure 24 are all annular structures, and the first annular seal 3 and the second annular seal 4 are also annular structures. The annular structure can be a rectangular ring structure, a rectangular ring structure with rounded corners, a trapezoidal ring structure, a pentagonal ring structure, or other structures including closed rings.

[0098] Alternatively, please refer to Figure 14 As shown, the seat mounting frame may include a front structural member 1b, a side structural member 1c, a rear structural member 1d, and a middle structural member 1e. The direction from the front structural member 1b to the rear structural member 1d is the same as the direction from the front of the vehicle to the rear. The front structural member 1b and the rear structural member 1d are spaced apart and connected by two side structural members 1c and one middle structural member 1e, with the middle structural member 1e located between the two side structural members 1c. The front structural member 1b, the side structural member 1c, the rear structural member 1d, and the middle structural member 1e are fixed together by welding. The front structural member 1b, one of the side structural members 1c, the middle structural member 1e, and the rear structural member 1d enclose an opening 1a, and the front structural member 1b, the other side structural member 1c, the middle structural member 1e, and the rear structural member 1d enclose another opening 1a. Each opening 1a is covered by a corresponding seat base plate 2, and a corresponding first annular seal 3 and a second annular seal 4 are provided between each opening 1a and the corresponding seat base plate 2.

[0099] In some embodiments, Figure 4 It can be Figure 2 Partial sectional view of the middle structure along direction AA Figure 2 Partial sectional view of the middle structure along direction BB. Figure 2 A partial sectional view of the middle structure along the direction CC or Figure 2 A partial sectional view of the middle structure along direction DD. If... Figure 4 yes Figure 2 A partial sectional view of the middle structure along direction AA, then Figure 4 The structure pressed together by the first annular seal 3 and the second annular seal 4 can be the front structural member 1b of the seat mounting frame 1. If Figure 4 yes Figure 2 A partial sectional view of the middle structure along direction BB, then Figure 4 The structure pressed together by the first annular seal 3 and the second annular seal 4 can be the side structure 1c of the seat mounting frame 1. If Figure 4 yes Figure 2 A partial sectional view of the middle structure along direction CC, then Figure 4 The structure pressed together by the first annular seal 3 and the second annular seal 4 can be the rear structural member 1d of the seat mounting frame 1. If Figure 5 yes Figure 2 A partial sectional view of the middle structure along direction DD, then Figure 4 The structure pressed together by the first annular seal 3 and the second annular seal 4 can be the middle structural component 1e of the seat mounting frame 1.

[0100] Alternatively, please refer to Figure 4 As shown, the material of the first annular seal 3 includes silicone foam or foamed sealant. The first annular seal 3 has good flexibility, and under the pressure of the first annular pressing part 21, the first annular seal 3 can fit well against the first annular pressed part 11. Even if there is a height difference surface at the connection between the front structural member 1b and the side structural member 1c (or a stepped structure at the connection due to the welding process), the first annular seal 3 can still fit well against the height difference surface, resulting in good sealing performance. Similarly, even if there is a height difference surface at the connection between the front structural member 1b and the middle structural member 1e, the connection between the middle structural member 1e and the rear structural member 1d, and the connection between the side structural member 1c and the rear structural member 1d, the first annular seal 3 can still fit well against the height difference surface, resulting in good sealing performance.

[0101] Alternatively, please refer to Figure 15 As shown, the second annular seal 4 includes an adhesive portion 41, which is provided with a mating groove 411 and a protrusion 412. The protrusion 412 protrudes from the wall of the mating groove 411. The mating groove 411 is inserted into the flange structure 24a mentioned above. The protrusion 412 fits against the flange structure 24a, and there is a large static friction between the protrusion 412 and the flange structure 24a.

[0102] The second annular seal 4 also includes a metal profile 42, which is embedded in the adhesive portion 41. In the cross-sectional view, the metal profile 42 has a U-shaped structure and partially surrounds the mating groove 411 and the flange structure 24a. The material of the adhesive portion 41 can be the same as that of the first annular seal 3. The rigidity of the second annular seal 4 is greater than that of the first annular seal 3.

[0103] The second annular seal 4 also includes a first elastic extension 413 and a second elastic extension 414. The first elastic extension 413 is used to fit tightly against the seat base plate 2, and the second elastic extension 414 is used to fit tightly against the seat mounting frame 1. The first elastic extension 413 and the second elastic extension 414 support each other and form an approximately annular tube structure.

[0104] In some embodiments of this application, the seat mounting assembly 10 has good waterproof sealing performance, and correspondingly, the seat mounting assembly 10 also has good windproof and dustproof performance. That is, the two sealing structures of the seat mounting assembly 10 can be used to effectively isolate the opening and the cockpit.

[0105] Secondly, embodiments of this application provide a vehicle that includes the seat mounting assembly described above. Accordingly, the vehicle also includes the technical effects described above, which will not be repeated here.

[0106] The vehicle type can be a minivan, commercial vehicle, or SUV. If classified by engine layout, the vehicle type can be a mid-engine vehicle, meaning the engine is positioned below the driver's compartment or passenger compartment relative to the vehicle body.

[0107] Additionally, the vehicle may include a carpet (not shown in the figure), and the second annular pressing portion 22 can press the carpet onto the second annular pressed portion 12 via the second annular seal 4. For example, the front structural member 1b, the side structural member 1c, and the rear structural member 1d can all press the carpet onto the second annular pressed portion 12 via the second annular seal 4, while the middle structural member 1e can be pressed onto the second annular pressed portion 12 via the second annular seal 4.

[0108] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
