Description

Technical Field

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

[0002] Some vehicles require door locks to be installed between the side door and the upper side panel beam. For example, some vehicles without a B-pillar require the lock body to be installed at the upper side panel beam. Installing door locks between the side door and the upper side panel beam may cause the following technical problems: Deterioration of sealing performance: Holes are usually made in the door lock installation area on the upper side beam of the side panel, which can easily form a path for water and air leakage, resulting in deterioration of the vehicle's sealing performance; Weakening of the upper side beam structure: Holes are made in the door lock installation area of ​​the upper side beam, which will damage the cavity structure of the upper side beam, resulting in a weakening of the upper side beam structure and a decrease in the torsional stiffness of the vehicle body. Insufficient collision safety: When a vehicle is involved in a side collision, the upper side beam needs to bear the load transmitted by the door lock. The weakened upper side beam is prone to local deformation, which adversely affects the integrity of the passenger compartment. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] like Figure 1 and Figure 2 The vehicle body structure shown includes a side upper beam, a door lock body 4, a first sealing strip 5, and a second sealing strip 6. The door lock body 4 is mounted on the side upper beam, and a clearance opening is provided on the side upper beam to allow passage of the door lock body 4 and / or the door lock latch 8 that matches the door lock body 4. The lengths of the first sealing strip 5 and the second sealing strip 6 extend along the length direction of the side upper beam, and the first sealing strip 5 and the second sealing strip 6 are mounted on the outer wall of the side upper beam. The first sealing strip 5 is located above the clearance opening, and the second sealing strip 6 is located below the clearance opening.

[0020] By adopting the above technical solution, by installing the first sealing strip 5 and the second sealing strip 6 on the side wall upper beam, the path of external water spray or airflow entering the passenger compartment through the avoidance opening can be blocked, thus ensuring the sealing performance of the vehicle.

[0021] In some embodiments, the upper side beam includes an upper beam body 1 and a mounting bracket 3 fixedly connected to the upper beam body 1, with the door lock body 4 mounted on the mounting bracket 3. By providing the mounting bracket 3, the impact of installing the door lock body 4 on the structural performance of the upper side beam can be reduced.

[0022] In some embodiments, the mounting bracket 3 is fixedly connected to the side of the upper side beam 1 closest to the vehicle interior. Properly positioning the mounting bracket 3 allows for efficient use of the space on the side of the upper side beam closest to the vehicle interior, helping to reduce the requirements for the internal space of the upper side beam and the size of the clearance opening.

[0023] In practice, the mounting bracket 3 can be fixedly connected to the inner plate 102 of the upper beam by welding, and the door lock body 4 can be detachably and fixedly mounted on the mounting bracket 3 by bolt fastening. The bolt fastening connection allows for the removal and replacement of the door lock body 4 to adapt to different car models' door lock types.

[0024] In some embodiments, the upper beam body 1 includes an outer upper beam plate 101, an inner upper beam plate 102, and an upper upper beam reinforcing plate 103. The upper edges of the outer upper beam plate 101, the upper edges of the reinforcing plate 103, and the upper edges of the inner upper beam plate 102 are stacked and overlapped. The lower edges of the outer upper beam plate 101, the lower edges of the reinforcing plate 103, and the lower edges of the inner upper beam plate 102 are stacked and overlapped. The outer upper beam plate 101 and the reinforcing plate 103 form a first cavity, and the reinforcing plate 103 and the inner upper beam plate 102 form a second cavity. A reasonable design of the upper beam body 1 helps to improve the structural performance of the side upper beam.

[0025] In practical implementation, the clearance opening extends through the upper side beam body 1 from the inside to the outside of the vehicle, forming a first clearance hole 104 on the outer plate 101 of the upper side beam, a second clearance hole 105 on the reinforcing plate 103 of the upper side beam, and a third clearance hole 106 on the inner plate 102 of the upper side beam. The door lock body 4 can extend into the inner cavity of the upper side beam body 1 through the clearance opening, which helps to reduce the difficulty of arranging the door lock body 4.

[0026] In some embodiments, the vehicle body structure includes a side door 2, on which a door lock latch 8 is installed that matches the door lock body 4. When the side door 2 is closed, a first sealing strip 5 contacts the side door 2 to form a seal above the clearance opening, and a second sealing strip 6 contacts the side door 2 to form a seal below the clearance opening. By installing the first sealing strip 5 and the second sealing strip 6 on the upper side beam of the side panel, two seals are formed, which can block the path of external water or airflow into the passenger compartment through the clearance opening, thus ensuring the sealing performance of the vehicle.

[0027] In some embodiments, the vehicle body structure includes two side doors 2, which form a suicide door configuration. The suicide door is configured to open or close via relative movement between the two side doors 2. In specific implementations, the two side doors 2 can be connected to the vehicle body via door hinges or a sliding mechanism. The suicide door configuration, especially after the elimination of the B-pillar, creates a larger entry and exit space. This application provides convenience for installing the door lock body 4 on the upper side beam of the side panel, which is particularly suitable for models with suicide doors.

[0028] In some embodiments, the vehicle body structure is a pillarless body structure. A pillarless body structure allows for greater entry and exit space, and this application facilitates the installation of the door lock body 4 on the upper side beam, making it particularly suitable for pillarless body structures.

[0029] In some embodiments, a third sealing strip 7 is installed on the vehicle side door 2. When the vehicle side door 2 is closed, the third sealing strip 7 contacts the upper side beam of the side panel to form a seal above the door lock latch 8 and the clearance opening. By setting the third sealing strip 7, the path of external water or airflow entering the passenger compartment through the clearance opening can be better blocked, thereby further ensuring the sealing performance of the vehicle.

[0030] As a preferred example, a first sealing strip 5, a third sealing strip 7, and a second sealing strip 6 form a triple seal between the upper side beam of the side panel and the vehicle side door 2. The first sealing strip 5 forms the first seal, located between the upper end of the vehicle side door 2 and the upper side beam of the side panel, used to block and guide some external rainwater and airflow. The third sealing strip 7 forms the second seal, covering the edge gap of the clearance opening. The second sealing strip 6 forms the third seal, capable of intercepting residual noise.

[0031] In practice, the first sealing strip 5 is installed on the upper side beam of the side panel and compressed to match the upper edge of the vehicle side door 2. The first sealing strip 5 can be a T-section foamed rubber strip, and its base can be fixed to the upper side beam of the side panel using clips or 3M tape. When the vehicle side door 2 is closed, the foamed part of the first sealing strip 5 is compressed by the upper edge of the vehicle side door 2, typically by 3mm-4mm, forming the first elastic sealing barrier, mainly used to block external water spray and high-speed airflow.

[0032] In practical implementation, the third sealing strip 7 serves as the main overlapping seal integrated into the vehicle side door 2. The third sealing strip 7 is installed on the inner door panel 202 near the clearance opening. The third sealing strip 7 can be a composite sealing strip, with the fixing part using dense rubber with good tensile strength, and the compression part using foamed rubber with good deformation performance. The third sealing strip 7 can be rigidly connected to the reinforcing ribs of the inner door panel 202 via clips or 3M tape. When the vehicle side door 2 is closed, the foam part of the third sealing strip 7 tightly overlaps with the upper side beam of the side panel, with a contact pressure typically greater than or equal to 5N / 100mm. This primarily serves to block external moisture and noise from entering the passenger compartment through openings such as the clearance opening. Simultaneously, the third sealing strip 7 also buffers the vibration of the vehicle side door 2, reducing the impact of the vibration on the sealing performance of the vehicle side door 2.

[0033] In practical implementation, the second sealing strip 6 is installed at the lower stop edge of the upper side beam of the side panel. The second sealing strip 6 can be a U-shaped sealing strip with a steel frame, which is engaged with the lower stop edge of the upper side beam of the side panel through a U-shaped groove. When the vehicle side door 2 is closed, the free end of the second sealing strip elastically overlaps with the sealing flange of the inner door panel 202, with a compression amount of typically 2mm-3mm, forming an inner sealing barrier to intercept residual moisture and high-frequency noise that were not blocked by the first two seals, especially wind noise above 600Hz.

[0034] The three seals work synergistically through layered interception and compensation. Layered interception: The first seal intercepts over 80% of external rainwater and airflow; the second seal blocks intrusion through gaps in the clearance opening, intercepting approximately 15% of external rainwater and airflow; and the third seal intercepts the remaining 5% of residual moisture and noise, resulting in a total sealing efficiency of ≥99%. Compensation synergy: When the first seal experiences slight loosening due to vibration, the second and third seals immediately compensate for the sealing pressure, ensuring overall sealing reliability. This three-seal structure reduces rainwater permeability in the door lock installation area by 90% and noise by 3-5 dB, superior to traditional B-pillar models.

[0035] In some embodiments, a latch mounting portion is provided on the inner panel 202 of the vehicle side door 2, and the door lock latch 8 is fixedly mounted on the latch mounting portion. A mounting portion reinforcement plate 203 is fixedly connected to the inner panel 202 to reinforce the latch mounting portion. Providing the mounting portion reinforcement plate 203 can improve the installation stability of the door lock latch 8.

[0036] In specific implementation, the vehicle side door 2 includes an outer door panel 201, an inner door panel 202, and a mounting reinforcement plate 203. The outer door panel 201 and the inner door panel 202 are fixedly connected together to form a door cavity. The mounting reinforcement plate 203 is located in the door cavity and is fixedly connected to the inner door panel 202 by welding.

[0037] When side door 2 is closed, the door cavity, the first cavity of the upper side beam, and the second cavity of the upper side beam form a multi-layered cavity structure, which better ensures the structural performance of the door lock mounting area. Using this body structure in B-pillarless models allows the torsional stiffness of the door lock mounting area to be restored to the level of traditional B-pillar-equipped models.
