Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a door sill beam and a vehicle. Background Technology
[0002] With the rapid development of new energy vehicles, their driving range has become a key indicator of user concern, directly impacting the convenience of travel. The overall vehicle weight directly affects the driving range; therefore, lightweight design of the vehicle body is necessary.
[0003] By using hollow aluminum alloy for the door sill beams, a lightweight design can be achieved. However, during vehicle operation, the hollow structure of the door sill beams can easily cause a whistling sound. Furthermore, when the vehicle is wading through water, water can enter the vehicle interior through the hollow structure of the door sill beams, thus affecting the user experience. Utility Model Content
[0004] In view of this, this application provides a door sill beam and a vehicle. By setting a sealing structure, the hollow structure of the door sill beam can be sealed to solve the problem of water entering the vehicle interior through the hollow structure of the door sill beam, which affects the user experience.
[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0006] In a first aspect, embodiments of this application provide a door sill beam, which includes:
[0007] A sill beam body, wherein the sill beam body has at least one internal cavity, and the internal cavity has a port at the end of the sill beam body;
[0008] A sealing structure comprising a skeleton and a flexible body, the flexible body being arranged around the outer periphery of the skeleton and sealingly connected to the end of the sill beam body to seal the port of the internal cavity;
[0009] The mounting component is disposed on the sill beam body and located within the internal cavity, and the sealing structure is connected to the mounting component.
[0010] The sill beam provided in this application embodiment has a sealing structure that can be fixed to the sill beam body via an mounting component. The sealing structure is disposed at the end of the sill beam body. The sealing structure can be used to seal the port of the internal cavity, so that the internal cavity can be in a sealed state, thereby preventing the internal environment of the sealed internal cavity from being connected to the external environment of the sill beam body. This reduces the possibility of resonance and howling phenomena occurring between the internal and external environments of the sealed internal cavity.
[0011] Furthermore, by sealing the ports of the internal cavity through the sealing structure, it is not easy for liquid to enter the internal cavity, thereby reducing the possibility of liquid accumulating in the internal cavity or even entering the vehicle interior through the internal cavity, which could affect the user experience.
[0012] During the installation of the sealing structure onto the sill beam body, the frame can move towards the internal cavity along the length of the sill beam body. At this time, the flexible body can deform to create a mutual abutting force with the sill beam body, thereby sealing the end of the internal cavity.
[0013] The skeleton enhances the overall strength of the sealing structure, ensuring a stable connection between the sealing structure and the sill beam body when impacted by liquids or other objects. The flexible body allows for deformation, which in turn enables a tighter connection between the sealing structure and the sill beam body, thereby improving the sealing effect of the sealing structure on the internal cavity.
[0014] In one possible implementation of this application, the flexible body includes an inner annular surface and an outer annular surface;
[0015] The inner ring surface is sealed to the skeleton, and the outer ring surface is sealed to the end of the sill beam body.
[0016] In one possible implementation of this application, the outer ring surface is provided with an inclined sealing portion, at least a portion of which is used for a sealing connection with the inner wall of the sill beam body;
[0017] Along the length of the sill beam body and pointing towards the end of the sill beam body, the longitudinal cross-sectional area of the inclined sealing part gradually increases, and the longitudinal cross-section is perpendicular to the length of the sill beam body.
[0018] In one possible implementation of this application, the outer ring surface is provided with a sealing lip, the sealing lip is located outside the inner cavity, and the sealing lip abuts against the outer end face of the sill beam body.
[0019] In one possible implementation of this application, the sealing lip is connected to the inclined sealing portion, and an opening towards the internal cavity is formed between the sealing lip and the inclined sealing portion.
[0020] In one possible implementation of this application, the inner annular surface is provided with a mounting groove, and a portion of the outer periphery of the skeleton is located in the mounting groove.
[0021] In one possible implementation of this application, the mounting component includes a connecting part and a supporting part connected together, the connecting part being connected to the sill beam body, and the supporting part being connected to the frame.
[0022] In one possible implementation of this application, a reserved gap is provided between the support and the frame along the length direction of the threshold beam body.
[0023] In one possible implementation of this application, a first connector is further included, which is passable through the sill beam body and the connecting portion, and the first connector is sealed to the sill beam body; and / or,
[0024] It also includes a second connector, which can be inserted into the frame and the support, and the second connector is sealed to the frame.
[0025] Secondly, embodiments of this application provide a vehicle that includes the sill beam found in any of the above embodiments.
[0026] The vehicle provided in this application embodiment can use an aluminum alloy frame with an internal cavity for the sill beam, thereby reducing the weight of the vehicle body. Since the sill beam includes a sealing structure, this structure can seal the ports of the internal cavity, thereby reducing the possibility of whistling and also reducing the possibility of liquid entering the vehicle interior.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0045] This application provides a door sill beam that can be applied to a vehicle. The door sill beam is typically located below the vehicle door. It can extend along the side of the vehicle body and connects the front and rear doors, making it an important part of the vehicle body structure.
[0046] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.
[0047] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.
[0048] By using hollow aluminum alloy for the door sill beams, a lightweight design can be achieved. However, during vehicle operation, the hollow structure of the door sill beams can easily cause a whistling sound. Furthermore, when the vehicle is wading through water, water can enter the vehicle interior through the hollow structure of the door sill beams, thus affecting the user experience.
[0049] The sill beam provided in this application embodiment can seal the port of the internal cavity of the sill beam body by setting a sealing structure at the end of the sill beam body. On the one hand, it can avoid resonance between the internal cavity and external airflow vibration, mechanical vibration, etc., thereby reducing the possibility of the sill beam producing a whistling sound. On the other hand, liquids (such as water) are less likely to enter the interior of the sill beam body, thereby reducing the possibility of water accumulation inside the sill beam or liquid entering the vehicle interior through the sill beam.
[0050] Based on this, refer to Figures 1 to 4 This application also provides a door sill beam 100. The door sill beam 100 includes a door sill beam body 110, a sealing structure 120, and a mounting component 130.
[0051] The sill beam body 110 has at least one internal cavity 110a. The internal cavity 110a has a port 110b at one end of the sill beam body 110. The sealing structure 120 includes a frame 121 and a flexible body 122. The flexible body 122 is arranged around the outer periphery of the frame 121. The flexible body 122 is sealingly connected to the end of the sill beam body 110 to seal the port 110b of the internal cavity 110a. A mounting member 130 is disposed on the sill beam body 110 and located within the internal cavity 110a. The sealing structure 120 is connected to the mounting member 130.
[0052] In this embodiment, the sealing structure 120 can be fixed to the sill beam body 110 via the mounting member 130. The sealing structure 120 is disposed at the end of the sill beam body 110. The sealing structure 120 can be used to seal the port 110b of the internal cavity 110a, so that the internal cavity 110a can be in a sealed state, thereby preventing the internal environment of the sealed internal cavity 110a from being connected to the external environment of the sill beam body 110, and thus reducing the possibility of resonance and howling between the internal and external environments of the sealed internal cavity 110a.
[0053] Furthermore, by sealing the port 110b of the internal cavity 110a with the sealing structure 120, it is not easy for liquid to enter the internal cavity 110a, thereby reducing the possibility of liquid accumulating in the internal cavity 110a or even entering the vehicle interior through the internal cavity 110a, which could affect the user experience.
[0054] During the installation of the sealing structure 120 on the sill beam body 110, the frame 121 can move towards the inner cavity 110a along the length direction X of the sill beam body 110. At this time, the flexible body 122 can deform to have a mutual abutting force with the sill beam body 110, so that the sealing structure 120 can seal the end of the inner cavity 110a.
[0055] The skeleton 121 enhances the overall strength of the sealing structure 120, ensuring a stable connection between the sealing structure 120 and the sill beam body 110 when impacted by liquids or other objects. The flexible body 122 can deform, allowing for a tighter connection between the sealing structure 120 and the sill beam body 110, thereby improving the sealing effect of the sealing structure 120 on the internal cavity 110a.
[0056] In some examples, the skeleton 121 may be, but is not limited to, a plastic structure. During the installation of the skeleton 121 onto the sill beam body 110, the skeleton 121 may undergo slight deformation so that the flexible body 122 of the sealing structure 120 can fit tightly against the sill beam body 110.
[0057] The mounting component 130 in this embodiment can be used to fix the sealing structure 120 to the sill beam body 110 to improve the connection reliability between the sealing structure 120 and the sill beam body 110.
[0058] In this embodiment, the specific structure of the mounting component 130 is not limited, as long as a stable connection between the sealing structure 120 and the sill beam body 110 can be achieved.
[0059] In this embodiment, the connection method between the mounting component 130 and the sill beam body 110, as well as the connection method between the mounting component 130 and the sealing structure 120, are not limited.
[0060] In some examples, since the internal cavity 110a extends through the sill beam body 110, both ends of the sill beam body 110 can be provided with sealing structures 120 to seal the two ports 110b of the internal cavity 110a respectively.
[0061] In some examples, when the sill beam body 110 is provided with multiple internal cavities 110a, each internal cavity 110a port 110b can be provided with a corresponding sealing structure 120, or, one or more of the internal cavities 110a ports 110b can be sealed as needed. No specific limitations are made in this embodiment.
[0062] In some examples, the frame 121 may be, but is not limited to, a plate-like structure, so that the structure of the frame 121 is simple, easy to manufacture, helps to reduce the manufacturing cost of the sealing structure 120, and can also promote the lightweight design of the vehicle body.
[0063] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The flexible body 122 may include an inner annular surface and an outer annular surface. The inner annular surface can be used for a sealing connection with the frame 121. The outer annular surface can be used for a sealing connection with the end of the sill beam body 110.
[0064] In this embodiment, since the flexible body 122 can be arranged around the outer periphery of the frame 121, the flexible body 122 can have a ring structure. The flexible body 122 can be fitted onto the outer periphery of the frame 121 through its inner ring surface and be sealed to the frame 121. The flexible body 122 can be transitionally fitted with the sill beam body 110 through its outer ring surface, so that the sealing structure 120 and the sill beam body 110 are sealed together through the tight fit between the flexible body 122 and the sill beam body 110.
[0065] In some examples, the shape of the sealing structure 120 can be set according to the cross-sectional shape of the internal cavity 110a. The cross-section of the internal cavity 110a can refer to the surface perpendicular to the length direction X of the sill beam body 110. When multiple internal cavities 110a have different cross-sectional shapes, various specifications of sealing structures 120 can be provided.
[0066] In some examples, the shape of the skeleton 121 can be the same as the cross-sectional shape of the internal cavity 110a. For example, when the cross-sectional shape of the internal cavity 110a is quadrilateral, the shape of the skeleton 121 can also be quadrilateral. The flexible body 122 is a quadrilateral ring structure.
[0067] In some examples, along the length direction X of the sill beam body 110, the orthographic projection of the outer torus of the flexible body 122 can be located inside the orthographic projection of the outer contour of the sill beam body 110.
[0068] Furthermore, in some embodiments of this application, reference is made to... Figure 3 and Figure 4 The outer ring surface is provided with an inclined sealing portion 1221. At least a portion of the inclined sealing portion 1221 is used for sealing connection with the inner wall of the sill beam body 110. Along the length direction X of the sill beam body 110 and pointing towards the end of the sill beam body 110, the longitudinal cross-sectional area of the inclined sealing portion 1221 gradually increases. The longitudinal section is perpendicular to the length direction X of the sill beam body 110.
[0069] In this embodiment, the inclined sealing part 1221 can be used to absorb the manufacturing tolerance of the sill beam body 110, so that the flexible body 122 can be tightly fitted to the sill beam body 110 through the inclined sealing part 1221, thereby ensuring that the sealing structure 120 and the sill beam body 110 can be sealed together.
[0070] Specifically, the inclined sealing portion 1221 can be used to connect with the inner wall of the sill beam body 110. At least a portion of the inclined sealing portion 1221 can be located within the inner cavity 110a. The inclined sealing portion 1221 has an inclined surface. Therefore, when the inner wall of the sill beam body 110 has different dimensions due to manufacturing tolerances, the depth to which the inclined sealing portion 1221 extends into the inner cavity 110a varies. The inclined surface of the inclined sealing portion 1221 can accommodate sill beam bodies 110 with different tolerances, and maintain a sealed connection between the inclined sealing portion 1221 and the sill beam body 110.
[0071] In some examples, the partially inclined seal 1221 may be located on the side of the skeleton 121 facing the interior space.
[0072] Based on this, refer to Figure 3 and Figure 4In some embodiments of this application, the outer ring surface may be provided with a sealing lip 1222. The sealing lip 1222 is located outside the inner cavity 110a. The sealing lip 1222 abuts against the outer end face of the sill beam body 110.
[0073] In this embodiment, the sealing lip 1222 abuts against the outer end face of the sill beam body 110, thereby achieving a double-layer seal between the sealing structure 120 and the sill beam body 110.
[0074] Specifically, the sealing lip 1222 can be sealed to the outer end face of the sill beam body 110 to achieve a first layer of sealing between the flexible body 122 and the sill beam body 110. By sealing the inclined sealing part 1221 to the inner wall of the sill beam body 110, a second layer of sealing between the flexible body 122 and the sill beam body 110 can be achieved. Thus, the sealing performance between the sealing structure 120 and the sill beam body 110 can be improved more effectively through the sealing lip 1222 and the inclined sealing part 1221.
[0075] Furthermore, in some embodiments of this application, reference is made to... Figure 3 and Figure 4 The sealing lip 1222 is connected to the inclined sealing portion 1221. An opening 122a is formed between the sealing lip 1222 and the inclined sealing portion 1221, facing the internal cavity 110a.
[0076] In this embodiment, the sealing lip 1222, connected to the inclined sealing portion 1221, can form an opening 122a facing the internal cavity 110a. Partial opening 122a can correspond to the outer end face of the sill beam body 110. Because the flexible body 122 is flexible, during the connection between the sealing structure 120 and the sill beam body 110, the sealing lip 1222 can deform, increasing the size of the opening 122a. This allows the sealing lip 1222 to fit tightly against the outer end face of the sill beam body 110, thus achieving a sealed connection between the sealing structure 120 and the sill beam body 110.
[0077] Furthermore, in some embodiments of this application, reference is made to... Figure 3 and Figure 4 The inner ring surface is provided with a mounting groove 122b. The outer periphery of part of the skeleton 121 is located in the mounting groove 122b.
[0078] In this embodiment of the application, by setting the outer periphery of part of the skeleton 121 to be located in the mounting groove 122b, the contact area between the skeleton 121 and the flexible body 122 can be increased, thereby improving the connection reliability between the skeleton 121 and the flexible body 122 and thus improving the sealing effect between the skeleton 121 and the flexible body 122.
[0079] In some examples, a portion of the flexible body 122 may be located on the side of the frame 121 facing the inner cavity 110a. A portion of the flexible body 122 may also be located on the side of the frame 121 facing away from the inner cavity 110a. A portion of the flexible body 122 may be located on the outer periphery of the frame 121, between the inner wall of the sill beam body 110 and the frame 121. Therefore, the frame 121 and the sill beam body 110 can be sealed together via the flexible body 122.
[0080] Furthermore, in some embodiments of this application, reference is made to... Figure 3 The mounting component 130 includes a connecting portion 131 and a supporting portion 132 connected together. The connecting portion 131 can be connected to the sill beam body 110. The supporting portion 132 can be connected to the frame 121.
[0081] In this embodiment, since the sealing structure 120 corresponds to the internal cavity 110a of the sill beam body 110, the support portion 132 can provide support for the sealing structure 120 within the internal cavity 110a. On the one hand, the support portion 132 can prevent the sealing structure 120 from easily moving towards the internal cavity 110a; on the other hand, the support portion 132 can provide support for the frame 121, thereby increasing the strength of the frame 121 and reducing the possibility of the frame 121 concave towards the internal cavity 110a.
[0082] In some examples, the connecting portion 131 may be connected to the inner wall of the sill beam body 110. There may be an angle between the connecting portion 131 and the support portion 132. For example, the angle between the connecting portion 131 and the support portion 132 may be approximately perpendicular. "Approximately perpendicular" can mean that the angle is between 80° and 100°. The angle may be, but is not limited to, 80°, 85°, 90°, 95°, or 100°.
[0083] In some examples, the material of the mounting member 130 is not limited in this application embodiment. The mounting member 130 can provide support for the sealing structure 120 through the support portion 132. For example, the mounting member 130 can be made of sheet metal.
[0084] Furthermore, in some embodiments of this application, reference is made to... Figure 4 Along the length direction X of the threshold beam body 110, there is a reserved gap 110c between the support part 132 and the frame 121.
[0085] In this embodiment of the application, during the installation of the sealing structure 120 and the sill beam body 110, a reserved gap 110c can be set so that the flexible body 122 can be pressed against the sill beam body 110, thereby improving the sealing reliability of the sealing structure 120 and the sill beam body 110.
[0086] Specifically, during the installation of the sealing structure 120 on the sill beam body 110, the frame 121 can move towards the inner cavity 110a so that the reserved gap 110c can gradually decrease. At this time, the flexible body 122 can fit tightly against the sill beam body 110 so that the flexible body 122 deforms, thereby sealing the connection between the flexible body 122 and the sill beam body 110.
[0087] In some examples, along the length direction X of the threshold beam body 110, the reserved gap 110c between the support 132 and the frame 121 can be greater than or equal to 0.5 mm and less than or equal to 1 mm.
[0088] When the reserved gap 110c between the support 132 and the frame 121 is less than 0.5mm, the movement distance of the sealing structure 120 towards the internal cavity 110a is limited during the installation of the sealing structure 120. This can easily lead to insufficient contact force between the flexible body 122 and the sill beam body 110, thus affecting the sealing effect between the flexible body 122 and the sill beam body 110, and consequently affecting the sealing effect between the sealing structure 120 and the sill beam body 110. When the reserved gap 110c between the support 132 and the frame 121 is greater than 1mm, the contact force between the flexible body 122 and the sill beam body 110 can easily become too large, increasing the assembly difficulty. Furthermore, it can also easily cause a local area of the frame 121 to move excessively towards the internal cavity 110a, resulting in severe deformation of the frame 121. Therefore, setting the reserved gap 110c to be greater than or equal to 0.5mm and less than or equal to 1mm can effectively solve the above technical problems.
[0089] Furthermore, in some embodiments of this application, reference is made to... Figure 3 The sill beam 100 may also include a first connector 140. The first connector 140 may be inserted through the sill beam body 110 and the connecting part 131, and the first connector 140 is sealed to the sill beam body 110.
[0090] In this embodiment, the mounting component 130 can be connected to the sill beam body 110 via the first connector 140. Since the first connector 140 can pass through both the sill beam body 110 and the connecting portion 131, the sill beam body 110 has a through hole through which the first connector 140 passes. By sealing the connection between the first connector 140 and the sill beam body 110, the possibility of liquid accumulating inside the sill beam body 110 can be prevented from entering the internal cavity 110a through the through hole.
[0091] In some examples, the portion of the first connector 140 located outside the inner cavity 110a can be sealed to the sill beam body 110.
[0092] For example, the first connector 140 and the sill beam body 110 can be sealed together with sealant. For example, Figure 3 Sealant can be applied within the circled area shown.
[0093] In some examples, the first connector 140 may be, but is not limited to, a pop rivet.
[0094] Furthermore, in some embodiments of this application, reference is made to... Figure 3 The threshold beam 100 also includes a second connector 150. The second connector 150 can be inserted into the frame 121 and the support 132, and the second connector 150 is sealed to the frame 121.
[0095] In this embodiment, the frame 121 of the sealing structure 120 can be connected to the support portion 132 of the mounting member 130 via the second connector 150. Since the second connector 150 can pass through both the frame 121 and the support portion 132, the frame 121 has a through hole through which the second connector 150 can pass. By sealing the connection between the second connector 150 and the frame 121, the possibility of liquid accumulating inside the sill beam body 110 can be prevented from entering the internal cavity 110a through the through hole.
[0096] In some examples, the portion of the second connector 150 located outside the internal cavity 110a can be sealed to the skeleton 121.
[0097] For example, the second connector 150 and the frame 121 can be sealed together with sealant. Figure 3 Sealant can be applied within the circled area shown.
[0098] In some examples, the second connector 150 may be, but is not limited to, a bolt. A nut may be provided on the side of the support 132 facing away from the frame 121. The bolt and nut connection can be used to lock the frame 121 and the mounting member 130 together.
[0099] This application embodiment can also provide a vehicle. The vehicle may include the sill beam 100 in any of the above embodiments.
[0100] In this embodiment, the sill beam 100 of the vehicle can be made of an aluminum alloy frame with an internal cavity 110a to reduce the weight of the vehicle body. Since the sill beam 100 includes a sealing structure 120, the sealing structure 120 can block the port 110b of the internal cavity 110a, thereby reducing the possibility of whistling and also reducing the possibility of liquid entering the vehicle interior.
