Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a roof assembly for highway vehicles and an industrial production method thereof. Background Technology

[0002] In the manufacturing process of highway vehicles (such as buses and trucks), the assembly of the roof assembly is one of the key steps in vehicle production. Traditional roof assemblies typically include components such as the body, roof frame, roof panel, and air conditioning system. The assembly process involves the installation and fixing of multiple independent parts, making it cumbersome and time-consuming. Specifically, the roof frame must first be welded to the vehicle body, and then operators need to climb onto the roof to install the roof panel and air conditioning system sequentially. Each step must be completed separately using bolts, riveting, or adhesives, resulting in low overall assembly efficiency.

[0003] Therefore, this application provides a roof assembly for highway vehicles and an industrial production method thereof. Summary of the Invention

[0004] The purpose of this application is to solve at least one technical problem raised in the background art.

[0005] This application provides a roof assembly for a highway vehicle, including a vehicle body, which is composed of a cargo box and a roof assembly. The roof assembly includes a roof frame made of high-strength steel, a roof panel mounted on the roof frame, and an air conditioning system mounted on the roof frame via an assembly mechanism. The assembly mechanism is used to securely install the air conditioning system and also provides protection for it. It includes an assembly frame, a protective housing adapted to the assembly frame, and a locking component provided on the surface of the protective housing for locking with the assembly frame. The assembly frame is welded to the roof frame, and the surface of the roof panel has a clearance groove adapted to the assembly frame. The air conditioning system components are encapsulated in the protective housing.

[0006] By adopting the above technical solution, the roof assembly consists of a roof frame made of high-strength steel and a lightweight heat-insulated roof panel. The roof frame is fixed to the vehicle body by welding to ensure structural strength and stability. The roof panel uses lightweight materials and is designed with a heat insulation layer to effectively reduce temperature fluctuations inside the vehicle and improve passenger comfort. The mounting frame is welded to the roof frame and a stable connection is achieved through locking components.

[0007] Preferably, the locking component includes a rectangular groove formed in the inner wall of the assembly frame, four sets of locking pins rotatably mounted in a rectangular array on the lower surface of the protective housing via a rotating shaft, a pull plate fixedly mounted on one end of the locking pins, a retainer disposed on the lower surface of the protective housing, and a driving component disposed on the lower surface of the protective housing for driving the retainer to move.

[0008] By adopting the above technical solution, the protective shell is placed in the clearance groove. When the pull plate rotates, it will drive the locking pin to rotate along the axis of the rotating shaft, thereby driving the locking pin to enter or disengage from the rectangular groove.

[0009] Preferably, the retainer consists of two transverse tie rods, two longitudinal tie rods, and four triangular adapters, and the four triangular adapters, together with the two transverse tie rods and the two longitudinal tie rods, form a rectangular retainer.

[0010] Preferably, the upper ends of the four triangular adapters are rotatably connected to the lower surface of the protective shell, one end of the two horizontal tie rods and the two vertical tie rods are rotatably connected to the surfaces of the four triangular adapters, and guide posts are fixedly installed on the positions of the two horizontal tie rods and the two vertical tie rods corresponding to the positions of the traction plate, and guide grooves for sliding of the guide posts are opened on the surface of the traction plate.

[0011] By adopting the above technical solution, when the four triangular adapters rotate 90 degrees counterclockwise, they will first drive the two horizontal tie rods and the two vertical tie rods to move away from each other, and then move closer to each other. At the same time as the two horizontal tie rods and the two vertical tie rods move away from each other and then move closer to each other, the two vertical tie rods will move to the left in sync, and the two horizontal tie rods will move backward. At this time, the guide post will slide in the guide groove and drive the pull plate to rotate, causing the locking post to rotate until it is disengaged from the rectangular groove. Conversely, when the four triangular adapters rotate 90 degrees clockwise, the two vertical tie rods will move to the right in sync, and the two horizontal tie rods will move forward in sync. At this time, the pull plate can be driven to rotate, causing the locking post to rotate until it enters the rectangular groove.

[0012] Preferably, one end of the guide post is provided with a roller, a clamping block is fixedly installed on the inner wall of the rectangular groove, the end of the clamping block near the roller is provided with a slope surface and a plane respectively, a sealing groove is opened on the upper surface of the assembly frame, and a sealing gasket is provided on the inner wall of the sealing groove.

[0013] By adopting the above technical solution, a sealing gasket is placed inside the seal, and then the protective shell is placed into the assembly frame. When the locking pin enters the rectangular groove, it will drive the roller to enter the plane along the slope of the pressing block, thereby fixing the protective shell on the assembly frame. The transition of the slope can drive the protective shell to press the sealing gasket, thereby improving the sealing performance.

[0014] Preferably, the driving component includes a first connecting rod rotatably connected to the lower surface of the protective housing, a first spur gear fixedly installed on the lower surface of the first connecting rod, a second spur gear rotatably connected to the lower surface of the protective housing, a protective cover fixedly installed on the lower surface of the protective housing, and a limiting component disposed on the surface of the protective cover. The first spur gear and the second spur gear mesh and drive each other. The end of the first connecting rod away from the first spur gear is hinged to the surface of the longitudinal tie rod behind the retainer. The surface of the protective cover is provided with a clearance notch for the first connecting rod to rotate.

[0015] By adopting the above technical solution, when the second spur gear rotates, it will drive the first spur gear to rotate, thereby driving the first connecting rod to rotate and causing the longitudinal tie rod located behind the cage to move, thus driving the entire cage to move. When the first connecting rod and the longitudinal tie rod are in a perpendicular state, the two lateral tie rods and the two longitudinal tie rods will move away from each other. When the first connecting rod and the longitudinal tie rod are in an inclined state, the two lateral tie rods and the two longitudinal tie rods will move closer to each other.

[0016] Preferably, the limiting component includes a through hole on the surface of the protective cover, an insertion rod that slides on the inner wall of the through hole, a protrusion fixedly installed on one end of the insertion rod, and a tension spring sleeved on the surface of the insertion rod, wherein the two ends of the tension spring are fixedly connected to the opposite surfaces of the protrusion and the protective cover, and one end of the insertion rod extends into the interior of the protective cover and is inserted into the tooth groove of the second spur gear.

[0017] By adopting the above technical solution, in the initial state, the tension spring can drive the insertion rod to insert into the tooth groove of the second spur gear, thereby restricting the rotation of the second spur gear. Therefore, the action of the first connecting rod can be restricted. When the insertion rod is pulled, the insertion rod disengages from the tooth groove of the second spur gear, thereby restoring the rotation of the second spur gear.

[0018] Preferably, the drive component further includes a second link rotatably connected to the lower surface of the protective housing, a first sprocket fixedly mounted on the lower surface of the second link, and a second sprocket fixedly mounted on the lower surface of the second spur gear. The first sprocket is connected to the second sprocket via a chain, and the end of the second link away from the first sprocket is hinged to a longitudinal tie rod located in front of the cage.

[0019] Preferably, the first spur gear, the second spur gear, and the second sprocket are all located inside the protective cover. An operating handle is rotatably connected to the lower surface of the protective cover, and one end of the operating handle extends into the interior of the protective cover and is fixedly connected to the shaft end of the second sprocket.

[0020] By adopting the above technical solution, when the operating handle is turned, the second spur gear and the second sprocket will be driven to rotate. The chain transmission can drive the first sprocket to rotate, which in turn drives the first connecting rod and the second connecting rod to rotate and drive the cage to move, thus improving the stability of the drive.

[0021] An industrial production method for highway vehicles includes the following steps:

[0022] Step 1: The roof panel is bonded and molded using adhesive to ensure a firm bond. After molding, it is installed on the roof rack.

[0023] Step 2: The air conditioning system is installed on the roof rack;

[0024] Step 3: Install the pre-assembled roof assembly onto the pre-treated carriage, precisely adjust its position, and then weld the roof frame to the carriage.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The roof assembly for highway vehicles and its industrial production method described in this application are installed separately by the vehicle body and the roof assembly. After the various structures on the roof assembly are installed, they are hoisted onto the vehicle body for welding. This eliminates the need to climb to the roof to install the roof panel and air conditioning system in sequence, thereby improving assembly efficiency.

[0027] 2. The roof assembly for highway vehicles and its industrial production method described in this application utilizes the three-stage linkage of "expansion-contraction-translation" formed by the transverse and longitudinal tie rods to ensure that the rollers smoothly transition to the plane locking along the slope of the clamping block, thereby enabling the rapid installation and removal of the protective shell.

[0028] 3. The roof assembly for highway vehicles and its industrial production method described in this application drive the second spur gear and the first sprocket through the operating handle, which simultaneously drives the first connecting rod and the second connecting rod to move, thereby achieving precise movement of the cage and improving the stability of the drive.

[0042] The following combination Figures 1 to 7 This application will be described in further detail below.

[0043] Example 1

[0044] Please refer to the following carefully. Figures 1 to 3 A roof assembly for a highway vehicle includes a vehicle body, which is composed of a cargo box 100 and a roof assembly 200. The roof assembly 200 includes a roof frame made of high-strength steel, a roof panel mounted on the roof frame, and an air conditioning system mounted on the roof frame via an assembly mechanism 300. The assembly mechanism 300 is used to securely install the air conditioning system and also provides protection for it. It includes an assembly frame 301, a protective housing 302 adapted to the assembly frame 301, and a locking component 400 provided on the surface of the protective housing 302 for locking with the assembly frame 301. The assembly frame 301 is welded to the roof frame, and the surface of the roof panel has a clearance groove adapted to the assembly frame 301. The air conditioning system components are encapsulated in the protective housing 302.

[0045] Specifically, the roof assembly 200 consists of a roof frame made of high-strength steel and a lightweight heat-insulated roof panel. The roof frame is fixed to the vehicle body 100 by welding to ensure structural strength and stability. The roof panel uses lightweight materials and is designed with a heat insulation layer to effectively reduce temperature fluctuations inside the vehicle and improve passenger comfort. The mounting frame 301 is welded to the roof frame and is securely connected by locking components 400.

[0046] Please refer to Figure 3 , Figure 4 and Figure 7 The locking component 400 includes a rectangular groove formed in the inner wall of the assembly frame 301, four sets of locking pins 401 rotatably mounted in a rectangular array on the lower surface of the protective housing 302 via a rotating shaft, a pull plate 402 fixedly mounted on one end of the locking pins 401, a retainer provided on the lower surface of the protective housing 302, and a drive component 500 provided on the lower surface of the protective housing 302 for driving the retainer to move.

[0047] Specifically, when the protective housing 302 is placed into the clearance groove, the pulling plate 402 rotates, which will drive the locking pin 401 to rotate along the axis of the rotating shaft, thereby driving the locking pin 401 into or out of the rectangular groove.

[0048] Please refer to Figure 4 and Figure 7 The retainer consists of two transverse tie rods 403, two longitudinal tie rods 404, and four triangular adapters 405. The four triangular adapters 405, together with the two transverse tie rods 403 and the two longitudinal tie rods 404, form a rectangular retainer. The upper ends of the four triangular adapters 405 are rotatably connected to the lower surface of the protective shell 302. One end of the two transverse tie rods 403 and the two longitudinal tie rods 404 are rotatably connected to the surface of the four triangular adapters 405, respectively. Guide posts 406 are fixedly installed on the two transverse tie rods 403 and the two longitudinal tie rods 404 at the positions corresponding to the pull plate 402. The surface of the pull plate 402 is provided with guide grooves 407 for the guide posts 406 to slide.

[0049] Specifically, when the four triangular adapters 405 rotate 90 degrees counterclockwise, they first drive the two horizontal tie rods 403 and the two vertical tie rods 404 to move away from each other, and then move closer together. Simultaneously, as the two horizontal tie rods 403 and the two vertical tie rods 404 move away from each other and then move closer together, the two vertical tie rods 404 move to the left, and the two horizontal tie rods 403 move backward. At this time, the guide post 406 slides within the guide groove 407, driving the pull plate 402 to rotate and causing the locking post 401 to rotate until it disengages from the rectangular groove. Conversely, when the four triangular adapters 405 rotate 90 degrees clockwise, the two vertical tie rods 404 move to the right, and the two horizontal tie rods 403 move forward. This drives the pull plate 402 to rotate and causes the locking post 401 to rotate until it enters the rectangular groove.

[0050] Please refer to Figure 3 and Figure 7 One end of the guide post 406 is provided with a roller 408, and a clamping block 409 is fixedly installed on the inner wall of the rectangular groove. The end of the clamping block 409 near the roller 408 is provided with a slope and a flat surface respectively. A sealing groove 410 is opened on the upper surface of the assembly frame 301, and a sealing gasket is provided on the inner wall of the sealing groove 410.

[0051] Specifically, a sealing gasket is placed in the sealing groove 410, and then the protective housing 302 is placed in the assembly frame 301. When the locking pin 401 enters the rectangular groove, it will drive the roller 408 to enter the plane along the slope of the pressing block 409, thereby fixing the protective housing 302 on the assembly frame 301. The transition of the slope can drive the protective housing 302 to press the sealing gasket, thereby improving the sealing performance.

[0052] Please refer to Figure 4 and Figure 6 The drive component 500 includes a first connecting rod 501 rotatably connected to the lower surface of the protective housing 302, a first spur gear 502 fixedly installed on the lower surface of the first connecting rod 501, a second spur gear 503 rotatably connected to the lower surface of the protective housing 302, a protective cover 504 fixedly installed on the lower surface of the protective housing 302, and a limiting component 600 provided on the surface of the protective cover 504. The first spur gear 502 and the second spur gear 503 mesh and drive each other. The end of the first connecting rod 501 away from the first spur gear 502 is hinged to the surface of the longitudinal tie rod 404 located behind the retainer. The surface of the protective cover 504 is provided with a clearance notch for the first connecting rod 501 to rotate.

[0053] Specifically, when the second spur gear 503 rotates, it drives the first spur gear 502 to rotate, which in turn drives the first connecting rod 501 to rotate and move the longitudinal tie rod 404 located behind the cage, thereby driving the entire cage to move. When the first connecting rod 501 and the longitudinal tie rod 404 are in a perpendicular state, the two transverse tie rods 403 and the two longitudinal tie rods 404 will move away from each other. When the first connecting rod 501 and the longitudinal tie rod 404 are in an inclined state, the two transverse tie rods 403 and the two longitudinal tie rods 404 will move closer to each other.

[0054] Please refer to Figure 6 The limiting component 600 includes a through hole on the surface of the protective cover 504, an insertion rod 601 that slides on the inner wall of the through hole, a protrusion fixedly installed on one end of the insertion rod 601, and a tension spring 602 sleeved on the surface of the insertion rod 601. The two ends of the tension spring 602 are fixedly connected to the protrusion and the opposite surface of the protective cover 504, respectively. One end of the insertion rod 601 extends into the interior of the protective cover 504 and is inserted into the tooth groove of the second spur gear 503.

[0055] Specifically, in the initial state, the tension spring 602 can drive the insertion rod 601 to insert into the tooth groove of the second spur gear 503, thereby restricting the rotation of the second spur gear 503 and thus restricting the action of the first connecting rod 501. When the insertion rod 601 is pulled, the insertion rod 601 disengages from the tooth groove of the second spur gear 503, thereby restoring the rotation of the second spur gear 503.

[0056] The working principle of this embodiment is as follows: First, the sealing gasket is placed into the sealing groove 410, and then the protective shell 302 is placed into the clearance groove. Then, the second spur gear 503 is rotated counterclockwise, which drives the first spur gear 502 to rotate clockwise. This drives the first connecting rod 501 to rotate clockwise, which in turn drives the longitudinal tie rod 404 located behind the cage. When the first connecting rod 501 rotates to a position perpendicular to the longitudinal tie rod 404, the two transverse tie rods 403 and the two longitudinal tie rods 404 will move away from each other. Then, the first connecting rod 501 continues to rotate, causing the first connecting rod 501 and the longitudinal tie rod 404 to be in an inclined state. At the same time, when the two transverse tie rods 403 and the two longitudinal tie rods 404 move, the triangular adapter 405 will rotate clockwise and pull the two longitudinal tie rods 404 to move synchronously to the right. The two transverse tie rods 403 will move forward. At this time, the guide post 406 will slide in the guide groove 407. The pull plate 402 is driven to rotate, causing the locking pin 401 to rotate and enter the rectangular groove. After the locking pin 401 enters the rectangular groove, it will drive the roller 408 to enter the plane along the slope of the pressing block 409, thereby fixing the protective shell 302 on the assembly frame 301. The slope transition can drive the protective shell 302 to press the sealing gasket, thereby improving the sealing performance. When unlocking is required, the second spur gear 503 is rotated clockwise, which will drive the first spur gear 502 to rotate counterclockwise and drive the two longitudinal tie rods 404 to move to the left in sync. The two transverse tie rods 403 will move backward, thereby driving the pull plate 402 to rotate and drive the roller 408 to rotate out of the rectangular groove, thus completing the unlocking. After the various structures on the roof assembly 200 are installed, they are hoisted to the carriage 100 for welding. There is no need to climb to the roof to install the roof panel and air conditioning system in sequence, thereby improving assembly efficiency.

[0057] Example 2

[0058] Compared with Embodiment 1, another implementation of this application is as follows:

[0059] Please refer to Figure 5 and Figure 6 The drive component 500 also includes a second connecting rod 505 rotatably connected to the lower surface of the protective housing 302, a first sprocket 506 fixedly mounted on the lower surface of the second connecting rod 505, and a second sprocket 507 fixedly mounted on the lower surface of the second spur gear 503. The first sprocket 506 is connected to the second sprocket 507 via a chain 508. The end of the second connecting rod 505 away from the first sprocket 506 is hinged to a longitudinal tie rod 404 located in front of the cage. The first spur gear 502, the second spur gear 503, and the second sprocket 507 are all inside the protective cover 504. An operating handle 509 is rotatably connected to the lower surface of the protective cover 504, and one end of the operating handle 509 extends into the interior of the protective cover 504 and is fixedly connected to the shaft end of the second sprocket 507.

[0060] Specifically, when the operating handle 509 is turned, the second spur gear 503 and the second sprocket 507 will be driven to rotate. The chain 508 will drive the first sprocket 506 to rotate, which will synchronously drive the first connecting rod 501 and the second connecting rod 505 to rotate and drive the cage to move, thus improving the stability of the drive.

[0061] The working principle of this embodiment is as follows: When the operator manually rotates the operating handle 509, the operating handle 509 is fixedly connected to the shaft end of the second sprocket 507, thus driving the second sprocket 507 to rotate synchronously. The second sprocket 507 is connected to the first sprocket 506 through the chain 508. The rotation of the second sprocket 507 will drive the chain 508 to move, thereby driving the first sprocket 506 to rotate synchronously. Therefore, the rotation of the first connecting rod 501 and the second connecting rod 505 will respectively drive the two longitudinal tie rods 404 on the cage to move. This design uses the operating handle 509 for centralized drive and utilizes the chain 508 and gear meshing to achieve synchronous transmission of the double connecting rod, which improves the transmission efficiency and stability of the driving force and ensures the reliable operation of the locking component 400.

[0064] Step 2: The air conditioning system is installed on the roof rack;

[0065] Step 3: Install the pre-assembled roof assembly 200 onto the pre-processed carriage 100, and after precisely adjusting the position, weld the roof frame to the carriage 100.
