Description

Technical Field

[0001] The present invention relates to the technical field of automobile transportation, and in particular to a vehicle frame and a car carrier. Background Art

[0002] The contents in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In the automotive logistics and transportation sector, car carriers are specialized vehicles used to transport cars. To improve transportation efficiency and reduce single-trip costs, some car carriers feature a double-deck loading platform design to increase the number of cars transported in a single trip.

[0004] In a vehicle frame with a double-deck loading platform design, in order to ensure smooth loading and unloading of vehicles on the upper and lower loading platforms, the lower loading platform is usually equipped with a rotatable tailgate at its rear end. The tailgate flips and forms a loading and unloading ramp with the ground, making it easier for vehicles to get on and off. The upper loading platform often uses a hydraulic lifting system. During loading and unloading, the upper loading platform is first lowered to a predetermined height as a whole, and then its rear end is tilted downward and overlapped with the lower loading platform. Finally, loading and unloading is completed with the help of the tailgate of the lower loading platform.

[0005] However, this frame structure design has the following technical defects:

[0006] 1. High operating precision is required: The smooth connection of the upper platform requires precise control of the descending height and tilt angle. Any deviation will affect the safety of loading and unloading;

[0007] 2. Frequent manual intervention: Operators need to continuously control the hydraulic system and achieve accurate positioning of the platform through visual inspection and repeated adjustments;

[0008] 3. Low operating efficiency: According to actual operation tests, the entire adjustment process usually takes 8-12 minutes, which seriously restricts loading and unloading efficiency. Summary of the Invention

[0009] In view of this, the object of the present invention is to provide a vehicle frame and a car carrier to at least overcome the technical problems of the known vehicle frame with a double-layer loading platform design, such as high operating precision requirements, frequent manual intervention, and low operating efficiency.

[0010] The purpose of the present invention is achieved through the following technical solutions:

[0017] A pushing member is provided at the bottom of the upper loading platform between the tail plate and the head end of the upper loading platform, the pushing member being configured to reciprocate along a first direction, and the tail plate being located on a movement path of the pushing member;

[0018] The upper loading platform is further provided with a locking member; the locking member is configured to lock or unlock the first slot and the first rotating shaft when the first slot is engaged with the first rotating shaft;

[0019] A blocking member is provided on the lower loading platform and is located outside the tailgate. The blocking member is configured to be capable of turning over outside the tailgate.

[0020] Optionally, the side of the pushing member facing the tail plate is an outwardly convex arc structure.

[0021] Optionally, the blocking member includes two blocking plates, and the two blocking plates are spaced apart and arranged on both sides of the tail plate along the second horizontal direction;

[0022] Both sides of the tail plate in the second horizontal direction are provided with blocking portions corresponding to the blocking plates.

[0023] Optionally, both the upper and lower sides of the blocking plate are in an arc-shaped structure, and the diameter of the upper side of the blocking plate is larger than the diameter of the lower side.

[0024] Optionally, the locking member is a buckle that can be extended and retracted along the second horizontal direction;

[0025] When the buckle is extended, the buckle presses the first slot and the first rotating shaft to lock the first slot and the first rotating shaft; when the buckle is retracted, the buckle no longer presses the first slot and the first rotating shaft to release the lock on the first slot and the first rotating shaft.

[0026] Optionally, there are two tail plates, and the two tail plates are spaced apart along the second horizontal direction.

[0027] On the other hand, the present invention discloses a car carrier, comprising the above-mentioned frame.

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, additional components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0036] Example 1

[0037] Please refer to Figures 1 to 3 Embodiment 1 of the present invention discloses a vehicle frame, particularly a vehicle frame suitable for use in a car carrier for transporting cars.

[0038] Figure 1 This is a schematic structural diagram of an exemplary vehicle frame disclosed in an embodiment of the present invention. Figure 1 In the embodiment shown, the vehicle frame may include an upper loading platform 10 and a lower loading platform 20 sequentially arranged in the height direction, wherein the upper loading platform 10 may be located above the lower loading platform 20, and the two may be parallel to each other.

[0039] Both the upper loading platform 10 and the lower loading platform 20 are equipped with a plurality of parking spaces arranged sequentially along a first horizontal direction, with each space being suitable for parking a single vehicle. The first horizontal direction described in this embodiment of the present invention can be understood as the length of the vehicle frame, specifically the length of the car carrier, i.e., the direction from the front to the rear of the car carrier. This design facilitates the sequential parking of vehicles in designated spaces as needed.

[0040] For example, the drawings of the present invention illustrate a case where both the upper loading platform 10 and the lower loading platform 20 are provided with four parking spaces arranged sequentially along a first horizontal direction, such that each of the upper loading platform 10 and the lower loading platform 20 can accommodate four vehicles. Of course, in other embodiments of the present invention, the number of parking spaces on each loading platform may be any other suitable number, which is not limited herein.

[0041] The upper loading platform 10 and the lower loading platform 20 each include a front end and a rear end that are opposite to each other in a first horizontal direction. The front end of the loading platform described in the embodiments of the present invention can be understood as the end of the loading platform closer to the front of the car carrier; correspondingly, the rear end of the loading platform can be understood as the end of the loading platform farther from the front of the car carrier.

[0042] Furthermore, the upper loading platform 10 is configured to be movable in height so as to adjust the height of the upper loading platform 10 according to the loading and unloading requirements of the vehicle. A hydraulic lifting system (not shown) can be arranged to drive the upper loading platform 10 to reciprocate in height.

[0043] On this basis, to enable smooth loading and unloading of vehicles on both the upper loading platform 10 and the lower loading platform 20, the vehicle frame disclosed in the embodiment of the present invention may further include a tailgate 30. The tailgate 30 is adapted to be shared by both loading platforms, thereby establishing a loading and unloading ramp between the corresponding loading platforms and the ground for vehicles to load and unload onto the loading platforms.

[0044] Specifically, the tail lift 30 is configured to selectively form a driving connection with the rear end of the upper loading platform 10 or the rear end of the lower loading platform 20. In other words, the tail lift 30 can form a driving connection with the rear end of the upper loading platform 10, but can also be released from the driving connection with the rear end of the upper loading platform 10 and formed a driving connection with the rear end of the lower loading platform 20, or vice versa.

[0045] Among them, when the tail lift 30 forms a driving connection with the rear end of the upper loading platform 10, the tail lift 30 can be flipped relative to the upper loading platform 10 to form an upper loading and unloading ramp between the upper loading platform 10 and the ground, and the upper loading and unloading ramp is mainly used for allowing cars to get on and off the upper loading platform 10; when the tail lift 30 forms a driving connection with the rear end of the lower loading platform 20, the tail lift 30 can be flipped relative to the lower loading platform 20 to form a lower loading and unloading ramp between the lower loading platform 20 and the ground, and the lower loading and unloading ramp is mainly used for allowing cars to get on and off the lower loading platform 20.

[0046] Based on the above configuration, when the vehicle frame is actually used for loading and unloading vehicles, it is only necessary to properly establish a driving connection between the tail lift 30 and the rear end of the upper loading platform 10 or the rear end of the lower loading platform 20. With the help of the tail lift 30, a loading and unloading ramp can be formed between the corresponding loading platform and the ground, thereby smoothly completing the vehicle loading and unloading operation. The vehicle loading and unloading operation can be divided into two situations: loading and unloading.

[0047] When loading, the order of loading the cars on the upper loading platform 10 first and then loading the cars on the lower loading platform 20 is as follows: first, the tail lift 30 is connected to the tail end of the upper loading platform 10 by a driving force, so that the tail lift 30 can be flipped to a suitable position relative to the upper loading platform 10 (for example, a position parallel to the horizontal plane); then, the upper loading platform 10 and the tail lift 30 are synchronously lowered to a suitable height in the height direction, and on this basis, the tail lift 30 is flipped relative to the upper loading platform 10, so that the end of the tail lift 30 away from the upper loading platform 10 is overlapped on the ground, so that the tail lift 30 serves as an upper loading and unloading ramp. After that, the cars to be loaded on the upper loading platform The cars on the loading platform 10 can be driven onto the upper loading platform 10 with the help of the tail lift 30. After the cars on the upper loading platform 10 are loaded, the upper loading platform 10 is raised to a predetermined height. Subsequently, the driving connection between the tail lift 30 and the rear end of the upper loading platform 10 is released, and the tail lift 30 is driven to the rear end of the lower loading platform 20. On this basis, the tail lift 30 is flipped relative to the lower loading platform 20 so that the end of the tail lift 30 away from the lower loading platform 20 is overlapped on the ground, thereby allowing the tail lift 30 to serve as a lower loading and unloading ramp. After that, the cars to be loaded on the lower loading platform 20 can be driven onto the lower loading platform 20 with the help of the tail lift 30.

[0048] When unloading, the order is exactly the opposite of that when loading, that is, the car on the lower loading platform 20 needs to be unloaded first, and then the car on the upper loading platform 10 needs to be unloaded. The specific process is as follows: first, the tail lift 30 is connected to the rear end of the lower loading platform 20 by driving, and then the tail lift 30 is turned relative to the lower loading platform 20 so that the end of the tail lift 30 away from the lower loading platform 20 is overlapped on the ground, so that the tail lift 30 serves as a lower loading and unloading ramp. After that, the car on the lower loading platform 20 can be driven out of the lower loading platform 20 with the help of the tail lift 30; wait for the lower loading platform 20 to be loaded. After the cars on the lower loading platform 20 are unloaded, the driving connection between the tail lift 30 and the rear end of the lower loading platform 20 is released, and the tail lift 30 is driven to the rear end of the upper loading platform 10. On this basis, the upper loading platform 10 is lowered to a suitable height. Then, the tail lift 30 is flipped relative to the upper loading platform 10 so that the end of the tail lift 30 away from the upper loading platform 10 is overlapped on the ground, thereby allowing the tail lift 30 to serve as an upper loading and unloading ramp. After that, the cars on the upper loading platform 10 can be driven off the upper loading platform 10 with the help of the tail lift 30.

[0049] It can be seen that the vehicle frame disclosed in the embodiment of the present invention forms a switchable single tailboard 30 dual-platform shared structure by arranging the tailboard 30 to be selectively connected to the rear end of the upper loading platform 10 or the rear end of the lower loading platform 20 by driving, so that the upper loading platform 10 and the lower loading platform 20 can share one tailboard 30. With this design, when loading and unloading the upper loading platform 10, it is only necessary to control the upper loading platform 10 to be lowered to an appropriate height, and there is no need to repeatedly operate the hydraulic lifting system to accurately adjust the position of the upper loading platform 10. This not only helps to simplify the operation difficulty and reduce manual intervention, but also helps to improve the loading and unloading efficiency.

[0050] In some embodiments, the tailgate 30 can selectively form a driving connection with the tail end of the upper loading platform 10 or the tail end of the lower loading platform 20 in the following manner.

[0051] Combine Figure 2 and Figure 3 As shown, the tail ends of the upper loading platform 10 and the lower loading platform 20 are respectively provided with a first rotating shaft 40 and a second rotating shaft 41 extending along a second horizontal direction and rotatable.

[0052] The horizontal second direction described in the embodiment of the present invention is perpendicular to the horizontal first direction, that is, the horizontal second direction can be understood as the width direction of the car carrier or the width direction of the car to be fixed.

[0053] The tail plate 30 is provided with a first slot 31 and a second slot 32 on the upper and lower sides thereof. The first slot 31 can be engaged with the first rotating shaft 40 , and the second slot 32 can be engaged with the second rotating shaft 41 .

[0054] A push member 42 is also provided at the bottom of the upper loading platform 10, located between the tailgate 30 and the front end of the upper loading platform 10. The push member 42 is configured to reciprocate in a first direction. For example, the push member 42 can be driven by a conventional linear actuator such as a pneumatic cylinder or an electric push rod. The tailgate 30 is located in the motion path of the push member 42, so that the push member 42 moving in the first direction can push the tailgate 30.

[0055] At the same time, a locking member 43 may also be provided on the upper loading platform 10. This locking member 43 is configured to lock or unlock the first slot 31 and the first rotating shaft 40 when the first slot 31 of the tailgate 30 is engaged with the first rotating shaft 40. For example, the locking member 43 may be a buckle that can extend and retract along a second horizontal direction to clamp the first slot 31 and the first rotating shaft 40 together. When the buckle extends, it presses against the first slot 31 and the first rotating shaft 40 to lock them together. When the buckle retracts, it no longer presses against the first slot 31 and the first rotating shaft 40 to unlock them.

[0056] The lower loading platform 20 is provided with a stopper 44 located outside the tailgate 30. The stopper 44 is configured to be tiltable outside the tailgate 30. For example, the stopper 44 may be hingedly connected to the rear end of the lower loading platform 20 and may be tiltable under the drive of a drive device (not shown) such as a motor provided on the lower loading platform 20. The tilting path of the stopper 44 is consistent with the tilting path of the tailgate 30, particularly the tailgate 30 that is drive-connected to the lower loading platform 20.

[0057] Based on the above configuration, assuming that in the initial state, the first and second slots 31, 32 of the tail lift 30 are respectively engaged with the first and second rotating shafts 40, 41, the locking member 43 locks the first slot 31 and the first rotating shaft 40 together, and the blocking member 44 flips to a vertical position to form a block on the outside of the tail lift 30, thereby reliably retaining the tail lift 30 between the upper loading platform 10 and the lower loading platform 20. During the subsequent normal operation of the car carrier to transport cars, the tail lift 30 can be maintained in this initial position, allowing the tail lift 30 to be stored while also forming a reliable block at the rear end of the lower loading platform 20.

[0058] When the tail lift 30 needs to be driven only with the upper loading platform 10 to load or unload vehicles on the upper loading platform 10, the blocking member 44 only needs to be flipped outwardly away from the tail lift 30. On this basis, the pushing member 42 moves in the first direction toward the tail lift 30 and pushes the tail lift 30. Because the first engaging slot 31 of the tail lift 30 is locked with the first rotating shaft 40 by the locking member 43, while the second engaging slot 32 of the tail lift 30 is not locked with the second rotating shaft 41, when the pushing member 42 pushes the tail lift 30, the first engaging slot 31 of the tail lift 30 rotates synchronously with the first rotating shaft 40, disengaging the second engaging slot 32 of the tail lift 30 from the second rotating shaft 41, thereby causing the tail lift 30 to flip outward. When the upper loading platform 10 is lowered to a suitable height, the tail lift 30 flips so that its lower side contacts the ground, thereby establishing the aforementioned upper loading and unloading ramp between the upper loading platform 10 and the ground through the tail lift 30.

[0059] On this basis, when a drive connection is required between the tailgate 30 and the lower loading platform 20, the upper loading platform 10 is first raised. During this process, the tailgate 30 tilts inward under its own weight, causing its second engaging slot 32 to continuously approach the second rotation axis 41. The pushing member 42 then retracts in the first direction away from the tailgate 30 until the second engaging slot 32 is aligned with the second rotation axis 41. The blocking member 44 then tilts inward until it pushes the tailgate 30 from the outside, allowing the second engaging slot 32 of the tailgate 30 to engage the second rotation axis 41. Subsequently, the locking member 43 releases the lock between the first engaging slot 31 and the first rotation axis 40.

[0060] Afterwards, the blocking member 44 slowly flips outward again. During this process, the pushing member 42 moves in the first direction toward the tailgate 30 and pushes the tailgate 30. Since the lock between the first slot 31 of the tailgate 30 and the first rotation axis 40 has been released, the first slot 31 will disengage from the first rotation axis 40, and the second slot 32 will rotate synchronously with the second rotation axis 41. During this process, the tailgate 30 is always supported by the blocking member 44 and slowly flips, thereby preventing the second slot 32 from disengaging from the second rotation axis 41. After the pushing member 42 moves to its maximum stroke and disengages from the tailgate 30, the tailgate 30 will continue to flip outward under the action of its own weight, supported by the blocking member 44, until the upper side of the tailgate 30 flips over and contacts the ground, thereby establishing an upper loading and unloading ramp between the lower loading platform 20 and the ground through the tailgate 30.

[0061] Accordingly, when the tailgate 30 needs to be restored to its initial state, the blocking member 44 is flipped inward to drive the tailgate 30 to flip inward until the first slot 31 of the tailgate 30 is re-engaged with the first rotation shaft 40, and then the locking member 43 can be used to lock the first slot 31 and the first rotation shaft 40 again.

[0062] It is worth noting that the above method not only realizes the selective driving connection between the tailgate 30 and the tail ends of the upper loading platform 10 and the lower loading platform 20, but also the entire process basically does not require human intervention, thereby further improving the degree of automation in loading and unloading vehicles and reducing manual labor intensity.

[0063] In some embodiments, as Figure 3 As shown, the side of the pushing member 42 that faces the tailgate 30, i.e., the side of the pushing member 42 that is used to push the tailgate 30, is convex and arc-shaped. This design helps reduce friction between the pushing member 42 and the tailgate 30 when pushing the tailgate 30, thereby preventing the pushing member 42 from hindering the flipping of the tailgate 30.

[0064] In some embodiments, there may be two tailgates 30, and the two tailgates 30 are spaced apart along the second horizontal direction. In this case, the aforementioned locking member 43, pushing member 42, and blocking member 44 correspond to each tailgate 30 one by one, so that both tailgates 30 can achieve the aforementioned drive connection with the upper loading platform 10 or the lower loading platform 20.

[0065] In some embodiments, as Figure 2 As shown, the blocking member 44 may further include two blocking plates 441 spaced apart along the second horizontal direction on either side of the tailgate 30. In this case, the tailgate 30 is provided with blocking portions 33 on both sides of the tailgate 30 in the second horizontal direction, corresponding to the blocking plates 441. When the tailgate 30 is in the initial state, the two blocking portions 33 on the tailgate 30 respectively abut against the two blocking plates 441, thereby reliably restraining the tailgate 30 in the initial state through the two blocking plates 441.

[0066] Furthermore, both the upper and lower sides of the blocking plate 441 are arc-shaped, and the diameter of the upper side of the blocking plate 441 is larger than the diameter of the lower side of the blocking plate 441. Such a design helps to further improve the reliability of the blocking plate 441 in restricting the tail plate 30 to the initial state.

[0067] On the other hand, an embodiment of the present invention further discloses a car carrier, comprising the above-mentioned frame. It is understood that by adopting the above-mentioned frame, the car carrier at least has the beneficial effects of the above-mentioned frame.

[0068] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
