Figure 1 The orientation of is used as a reference. The position of the mounting seat 2 relative to the supporting seat 3 is defined as "upper"; the position of the supporting rod 11 relative to the sleeve 12 is defined as "inner".

[0029] As mentioned above, an articulated vehicle is a wheeled vehicle or tracked vehicle consisting of two or more vehicle bodies connected by a hinge. It uses a special hydraulic mechanism to enable the vehicle bodies to move relatively in the horizontal plane, vertical longitudinal section or cross section, and change the direction of travel by rotating the connecting rings between the vehicle bodies. Articulated vehicles play an important role in various fields, especially in situations where large amounts of materials or passengers need to be transported.

[0030] The hood, also known as the engine cover, is an important component of the car body. It is located on the top of the engine compartment and plays the role of protecting from rain and sun, and insulating from heat and sound.

[0031] During routine maintenance and troubleshooting of articulated trucks, it is often necessary to lift the engine hood so that the operator can enter the engine compartment to carry out operations. The engine hood is heavy and may weigh more than 500kg. If the lifting cylinder fails, the engine hood will fall and cause serious injuries to the operator below. Therefore, after the engine hood is lifted, a support device is required to ensure the safety of the operator. However, the engine hood support device on the market is a support rod with a non-adjustable length, which cannot adapt to different engine hood opening angles, resulting in the engine hood support rod being too long and inconvenient to store.

[0032] In order to solve at least one of the technical problems existing in the prior art or related art, the embodiment of the present application provides a hood support device, including: a telescopic rod, a mounting seat, a support seat and a storage seat, wherein the telescopic rod includes: a support rod and a sleeve, the support rod is arranged in the sleeve, the support rod and the sleeve are provided with a plurality of positioning holes, and the positioning pins are arranged in the positioning holes; the mounting seat and the storage seat are respectively fixed on the hood, and the support seat is arranged on the frame; one end of the sleeve is hinged with the mounting seat; the support seat is used to fix the support rod; and the storage seat is used to store the telescopic rod. When the hood needs to be supported, the support rod can be slid in the sleeve, adjusted to a suitable length, the positioning pin is inserted into the corresponding positioning hole, and the support rod is placed in the support seat to complete the fixation, and the combined length of the support rod and the sleeve can be adjusted with the opening angle of the hood. When the hood does not need to be supported, the support rod can be slid in the sleeve to the shortest length and then fixed with the positioning pin, the support rod is rotated around the mounting seat, and the support rod is placed in the storage groove on the storage seat. At this time, the entire hood support device is fixed on the hood frame, which can save storage space.

[0033] The following describes an engine hood support device according to some embodiments provided by the present application with reference to the accompanying drawings.

[0034] See also Figures 1 to 7An engine hood support device provided in an embodiment of the present application includes: a telescopic rod 1, a mounting seat 2, a support seat 3 and a storage seat 4, wherein the telescopic rod 1 includes: a support rod 11 and a sleeve 12, the support rod 11 is arranged in the sleeve 12, and a plurality of positioning holes 13 are provided on the support rod 11 and the sleeve 12, and the positioning pins 14 are arranged in the positioning holes 13; the mounting seat 2 and the storage seat 4 are respectively fixed on the engine hood, and the support seat 3 is arranged on the frame; one end of the sleeve 12 is hinged to the mounting seat 2; the support seat 3 is used to fix the support rod 11; the storage seat 4 is used to store the telescopic rod 1.

[0035] like Figure 1 As shown, the support rod 11 is arranged in the sleeve 12 to form a telescopic structure. The support rod 11 can be extended or shortened in the sleeve 12. By changing the combined length of the support rod 11 and the sleeve 12, the opening angle of the engine hood can be adapted. When the positioning pin 14 is inserted into the positioning hole 13, as shown in FIG. Figure 2 As shown, the relative position of the support rod 11 and the sleeve 12 is fixed, and the combined length of the support rod 11 and the sleeve 12 is also fixed. The mounting seat 2 and the storage seat 4 are arranged on the frame of the engine hood, and the support seat 3 is arranged on the vehicle frame. When the engine hood needs to be supported, the support rod 11 can be slid in the sleeve 12, and after adjusting to a suitable length, the positioning pin 14 is inserted into the corresponding positioning hole 13, and the support rod 11 is rotated around the mounting seat 2, and the support rod 11 is placed in the support seat 3, and the gravity of the engine hood is used to complete the fixation. When the engine hood does not need to be supported, the support rod 11 can be slid in the sleeve 12 to the shortest length and then fixed with the positioning pin 14, and the support rod 11 is rotated around the mounting seat 2, and the support rod 11 is placed in the storage groove on the storage seat 4. At this time, the entire engine hood support device is fixed on the engine hood frame, which can save storage space.

[0036] Furthermore, the support rod 11 and the sleeve 12 are both provided with equally spaced positioning holes 13 along the length direction. When the positioning holes 13 of the support rod 11 and the sleeve 12 are aligned, the positioning pin 14 can be inserted into the positioning hole 13 to achieve axial positioning, thereby fixing the combined length of the support rod 11 and the sleeve 12. The number of positioning holes 13 on the support rod 11 can be the same as the number of positioning holes 13 on the sleeve 12; the number of positioning holes 13 on the support rod 11 can also be different from the number of positioning holes 13 on the sleeve 12, for example, the support rod 11 is provided with 5 positioning holes 13, and the sleeve 12 is provided with 5 positioning holes 13; or, the support rod 11 is provided with 6 positioning holes 13, and the sleeve 12 is provided with 8 positioning holes 13. It can be understood that the number of positioning holes 13 can affect the adjustment range of the combined length of the support rod 11 and the sleeve 12. The more the number of positioning holes 13 is set, the finer the adjustment range of the combined length of the support rod 11 and the sleeve 12.
