Description

Technical Field

[0001] This utility model relates to the field of truck front cover technology, and in particular to a truck front cover support mechanism. Background Technology

[0002] The truck hood is similar to the hood of a small car. However, the difference is that the hood of a small car is generally horizontal, and when you need to view the engine compartment, you need to flip the hood up from its horizontal position to an upward tilt. The truck hood, on the other hand, is located at the front of the truck and is vertical. When you need to view the internal structure of the hood, you need to flip the hood up from its vertical position to an upward tilt.

[0003] Existing truck front cover supports generally use gas springs and locking structures. When the front cover is open, the gas spring provides support, and when the front cover is closed, the gas spring is compressed and locked by the locking structure. For example, Chinese invention patent CN109823411B discloses a long-nose truck engine cover flipping limit and locking device. In this structure, the locking mechanism is relatively complex, occupies a large space, and is difficult to maintain. Utility Model Content

Detailed Implementation

[0022] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] A truck front cover support mechanism, reference Figures 1 to 4 The truck's internal structure includes a vehicle floor 1 and a front bulkhead 2. The vehicle floor 1 is fixedly connected to the truck chassis. The front bulkhead 2 is fixedly installed on the vehicle floor 1. The front cover 3 is hinged to the front bulkhead 2. The hinge is connected by a hinge, which allows the front cover 3 to be flipped.

[0024] Between the front cover 3, the outer front panel 2, and the vehicle floor 1, a retractable support and a locking mechanism are provided. The retractable support is used to support the front cover 3 when it is open, and the locking mechanism is used to lock the front cover 3 when it is closed. There are two sets of retractable support and locking mechanism, which are respectively set on both sides of the front cover 3 to provide more stable support for the front cover 3.

[0025] In this embodiment, the retractable support component is a gas spring 4, which has a simple structure and is easy to use. In other embodiments, structures such as helical spring telescopic rods can also be used, as long as they can effectively support the front cover 3.

[0026] The gas spring 4 is installed with an upper bracket 5 on the front cover 3 and a lower bracket 6 on the vehicle floor 1. Both ends of the gas spring 4 are hinged to the upper bracket 5 and the lower bracket 6 respectively. The lower bracket 6 is provided with a pin 7, which is fixedly connected to the lower bracket 6. One end of the gas spring 4 is rotatably connected to the pin 7, and the connection end is located on the outside of the lower bracket 6. The lower bracket 6 has a cavity on its inner side. The overall structure is U-shaped. The middle part of the pin 7 is located in the cavity of the lower bracket 6 and is used to connect with the locking mechanism.

[0027] The locking mechanism includes a mounting bracket 8 fixedly connected to the front cover 3. A fixing rod is fixed on the mounting bracket 8. A locking plate 9 is rotatably mounted on the fixing rod. A locking groove 10 is provided at the lower end of the locking plate 9, and an elastic connector is connected to the upper end. The locking groove 10 divides the lower end of the locking plate 9 into a short end 11 and a long end 12. The long end 12 is closer to the front cover 3, and the short end 11 is away from the front cover 3.

[0028] The elastic connector includes a connecting rod 13, one end of which is provided with a connecting part 18. The connecting part 18 has an inverted U-shaped structure. A locking plate 9 is provided in a notch below the connecting part 18. A connecting hole is provided coaxially on the connecting part 18 and the locking plate 9. A connecting shaft 19 is provided in the connecting hole. The connecting shaft 19 is fixedly connected to the connecting part 18 and rotatably connected to the locking plate 9. An elastic element is provided on the connecting rod 13. In this embodiment, the elastic element is a support spring 17. A limit ring 14 is rotatably provided on the mounting bracket 8. One end of the connecting rod 13 is sleeved in the limit ring 14. One end of the support spring 17 is fixedly connected to the connecting part 18, and the other end is fixedly connected to the limit ring 14. Rotating rods 15 are provided at both ends of the limit ring 14. Mounting limit grooves 16 are provided on both sides of the upper end of the mounting bracket 8. The rotating rods 15 are located in the mounting limit grooves 16.

[0029] The locking mechanism in this embodiment has a simple structure. The pin is connected to the gas spring, serving as both the rotation shaft of the gas spring and providing support for the locking plate. This makes the structure more compact, occupies less space, and is simple to install and maintain.

[0030] The working principle of this embodiment is as follows:

[0031] When the front cover 3 is closed, the gas spring 4 retracts. At this time, the pin 7 is in the limiting groove 16 of the locking plate 9. Under the action of the support spring 17, the locking plate 9 is in an inclined state, with one side of its lower long end 12 abutting against the mounting bracket 8, and the upper end of the locking plate 9 moving away from the front cover 3. In this state, the elastic force of the support spring 17 is greater than the force of the gas spring 4, so that the front cover 3 remains in the closed state. (Reference) Figure 3 ;

[0032] During the opening process of the front cover 3, the operator manually flips the front cover 3, applying an opening flipping force. Subsequently, the pin 7 abuts against the short end 11 of the locking plate 9. As the front cover 3 continues to flip open, the locking plate 9 rotates. During this rotation, the upper end of the locking plate 9 slowly approaches the front cover 3 and eventually abuts against the mounting bracket 8. During this process, the locking plate 9 pushes the connecting rod 13 upwards and then downwards. During the upward movement, the support spring 17 is compressed. To open the front cover 3, the operator needs to overcome the elastic force of this support spring 17. When the locking plate 9 rotates from one side of the vertical direction to the other, the support spring 17 is released, pushing the upper end of the locking plate 9 to abut against the mounting bracket 8. At this point, the tilt direction of the locking plate 9 is opposite to its initial position. The orientation of the limiting groove 16 allows the locking plate 9 to disengage from the pin 7, thus allowing the front cover 3 to open. Under the action of the gas spring 4, it fully opens. The locking mechanism after opening is referenced. Figure 4 ;

[0033] During the closing process of the front cover 3, the user manually flips the front cover 3, applying a closing flipping force. When the front cover 3 is about to close, the pin 7 first abuts against the long end 12 at the lower end of the locking plate 9. As the front cover 3 continues to close, the user increases the force, pressing the front cover 3. Subsequently, the pin 7 pushes the locking plate 9 to rotate through the long end 12. During the rotation, the upper end of the locking plate 9 moves away from the front cover 3, while the lower end gradually approaches the mounting bracket 8. Finally, the long end 12 at the lower end of the locking plate 9 abuts against the mounting bracket 8. At this time, the pin 7 is located in the locking groove 10 of the locking plate 9, and the locking plate 9 is in an inclined state with its upper end moving away from the mounting bracket 8. At this time, the support spring 17 applies a force to the upper end of the locking plate 9, keeping the locking plate 9 in this state. Without the action of external force, the locking mechanism will remain in this state unless the action of external force can overcome the elastic force of the spring to open the front cover 3.

[0034] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
