[0028] This utility model proposes a support device 100 for the engine hood of a vehicle.

[0029] Please see Figures 1 to 4 In one embodiment of the present invention, the engine hood support device 100 of the vehicle has a first opening at the bottom of the engine hood; the support device 100 includes a support rod 10 and a mounting structure 20; wherein, the two ends of the support rod 10 are a mounting end 11 and a support end 12, respectively, and the support end 12 forms a support plug 121, which is used to insert into the first opening to support the engine hood; the mounting structure 20 includes a snap-fit ​​seat 21 and a locking assembly 22, the snap-fit ​​seat 21 is mounted on the mounting end 11, the locking assembly 22 is mounted on the snap-fit ​​seat 21, the snap-fit ​​seat 21 forms a snap-fit ​​groove 211, and the snap-fit ​​groove 211 is used to snap-fit ​​with the vehicle frame 200, so that the snap-fit ​​seat 21 can support the frame 200, and the locking assembly 22 can lock-fit with the frame 200.

[0030] The technical solution of this utility model involves inserting the support plug 121 into the first opening at the bottom of the engine hood, so that the support rod 10 is vertically positioned between the engine hood and the frame 200. Then, the snap-fit ​​slot 211 of the snap-fit ​​seat 21 is aligned with the frame 200 and pressed down until the snap-fit ​​slot 211 and the frame 200 form a snap-fit ​​engagement. At this point, the locking assembly 22 and the frame 200 are locked together, and the support rod 10 is fixed to the frame 200, stably supporting the engine hood. Because the snap-fit ​​slot 211 and the frame 200 are engaged, and the locking assembly 22 and the frame 200 are also engaged, the support rod 10 remains fixed to the frame 200 during vehicle production line operation and will not fall off the frame 200, thus preventing the support rod 10 from falling into the production line equipment and causing equipment downtime. The snap-fit ​​slot 211 directly engages with the frame 200, and the locking assembly 22 directly locks the frame 200, requiring no additional parts, resulting in a simple structure and quick installation.

[0031] In one embodiment of the present invention, the snap-fit ​​seat 21 includes a bottom plate 212, a top plate 213 and a side plate 214. The bottom plate 212 and the top plate 213 are respectively connected to the two sides of the side plate 214 to form a snap-fit ​​groove 211. The opening 2111 of the snap-fit ​​groove 211 is set directly opposite the side plate 214. The frame 200 can enter the snap-fit ​​groove 211 through the opening 2111 and engage with the snap-fit ​​groove 211.

[0032] Specifically, the snap-fit ​​seat 21 consists of a base plate 212, a top plate 213, and a side plate 214. The side plate 214 is fixedly connected to the mounting end 11 of the support rod 10. The base plate 212 and the top plate 213 are vertically welded or integrally formed on the upper and lower sides of the side plate 214, respectively. The three together form a snap-fit ​​groove 211 with a "U"-shaped cross-section. The groove opening 2111 faces the side plate 214, that is, it is open towards the frame 200. In use, the frame 200 enters the snap-fit ​​groove 211 horizontally through the groove opening 2111. The base plate 212 and the top plate 213 together restrict the horizontal displacement of the support rod 10; the side plate 214 restricts the vertical displacement of the support rod 10. Thus, the frame 200 is clamped between the bottom plate 212 and the top plate 213, and at the same time abuts against the side plate 214, achieving three-way limiting. Furthermore, the support rod 10 and the frame 200 form a rigid whole, which can effectively prevent the support rod 10 from falling into the equipment on the production line.

[0033] In one embodiment of the present invention, the top plate 213 is bent away from the side plate 214 at one end in a direction away from the bottom plate 212, so that the slot 2111 is gradually widened in a direction away from the side plate 214.

[0034] Specifically, such as Figure 2As shown, the top plate 213 is bent away from the side plate 214 at one end, away from the bottom plate 212, causing the slot 2111 to gradually widen away from the side plate 214, forming a trumpet-shaped slot 2111. When the snap-fit ​​seat 21 is installed on the frame 200, the frame 200 first contacts the gradually widening slot 2111, and smoothly enters the snap-fit ​​slot 211 through the guidance of the bent section. This allows for quick insertion without precise alignment, improving assembly efficiency and reducing manufacturing and subsequent maintenance costs.

[0035] In one embodiment of the present invention, the bottom plate 212 protrudes toward the top plate 213 to form a snap-fit ​​protrusion 2121, and the snap-fit ​​protrusion 2121, the top plate 213 and the side plate 214 surround to form a snap-fit ​​groove 211.

[0036] Specifically, such as Figure 2 As shown, the bottom plate 212 protrudes towards the top plate 213 to form a snap-fit ​​protrusion 2121. This protrusion, together with the top plate 213 and the side plate 214, forms a snap-fit ​​groove 211. When the snap-fit ​​seat 21 is installed on the frame 200, the frame 200 is clamped between the snap-fit ​​protrusion 2121 and the top plate 213, achieving a snap-fit ​​engagement. The snap-fit ​​protrusion 2121 reduces the effective height within the groove, resulting in a tighter clamping between the frame 200, the protrusion, and the top plate 213. This significantly reduces the horizontal sway of the support device 100 relative to the frame 200, preventing it from loosening due to vibration during vehicle production line transfer and avoiding it falling into the production line equipment and causing downtime. The protrusion structure is simple and can be formed in one piece without adding extra parts, which reduces manufacturing difficulty and improves assembly efficiency.

[0037] In one embodiment of the present invention, the snap-fit ​​protrusion 2121 extends along the side plate 214 in the direction of the slot 2111 of the snap-fit ​​groove 211. The two ends of the snap-fit ​​protrusion 2121 along its extension direction are a connecting end and a guiding end, respectively. The connecting end is connected to the side plate 214, and the guiding end is set close to the slot 2111. The end face of the guiding end forms a guiding surface 2122, and the guiding surface 2122 is inclined toward the bottom plate 212 along the direction of the side plate 214 in the direction of the slot 2111 of the snap-fit ​​groove 211.

[0038] Furthermore, the snap-fit ​​protrusion 2121 extends along the side plate 214 towards the slot 2111, with its connecting end integrally formed with the side plate 214, and its guide end positioned close to the slot 2111. The end face of the guide end forms a guide surface 2122, which slopes from the side plate 214 toward the slot 2111 towards the bottom plate 212. When the snap-fit ​​seat 21 is installed on the frame 200, the guide surface 2122 first contacts the frame 200, guiding the frame 200 smoothly into the snap-fit ​​slot 211 via the inclined surface, enabling rapid assembly without precise alignment; the guide surface 2122 simultaneously provides a gradually increasing clamping force, causing the frame 200 to be gradually clamped by the snap-fit ​​protrusion 2121 and the top plate 213 during entry, improving snap-fit ​​stability. The guide surface 2122 and the snap-fit ​​protrusion 2121 are integrally formed, requiring no additional parts, resulting in a simple structure, reduced manufacturing and assembly costs, and effectively reduced installation resistance caused by alignment errors.

[0039] In one embodiment of this utility model, the guide surface 2122 is an arc surface protruding towards the top plate 213.

[0040] Furthermore, the guide surface 2122 is an arc-shaped surface protruding towards the top plate 213. The arc-shaped surface smoothly transitions from the connecting end to the guide end and continues to extend along the side plate 214 in the direction pointing towards the slot 2111. When the snap-fit ​​seat 21 is installed on the frame 200, the frame 200 first contacts the arc-shaped surface. The arc-shaped surface provides continuously changing tangential guidance, allowing the frame 200 to be gradually lifted during horizontal advancement and smoothly slide into the snap-fit ​​slot 211. The curvature of the arc-shaped surface causes the contact point to continuously change, reducing local friction and lowering insertion resistance. The arc-shaped surface and the snap-fit ​​protrusion 2121 are integrally formed, eliminating the need for additional parts, which simplifies the mold structure, improves assembly smoothness, and further shortens the installation time.

[0041] In one embodiment of the present invention, the frame 200 has a second opening 201, and the locking assembly 22 includes a handle 221 and a locking bar 222. One end of the handle 221 is hinged to the locking seat 21, and the other end of the handle 221 is equipped with the locking bar 222. The extension directions of the handle 221 and the locking bar 222 are set at an angle. The locking bar 222 can rotate with the handle 221 to insert into the second opening 201 when the locking seat 21 is supported on the frame 200, so as to lock and engage with the frame 200.

[0042] Specifically, as shown in the figure, the frame 200 has a second opening 201. The locking assembly 22 consists of a handle 221 and a locking bar 222: one end of the handle 221 is hinged to the locking seat 21, and the other end is fixed to the locking bar 222, with their extension directions intersecting at an angle. When the locking seat 21 is supported on the frame 200 through the locking groove 211, the operator only needs to rotate the handle 221, and the locking bar 222 will swing synchronously with the handle 221 until it is inserted into the second opening 201 of the frame 200, thus achieving locking engagement with the frame 200. Under the action of gravity, the locking bar 222 can remain inserted into the second opening 201 to achieve continuous locking engagement with the frame 200. Rotating the handle 221 in the opposite direction will disengage the locking bar 222 from the second opening 201, completing the unlocking process. This structure converts rotational motion into pin action, and the entire locking process can be completed with one hand without additional tools. At the same time, the insertion direction of the locking rod 222 and the second opening 201 is perpendicular to the snap-fit ​​direction of the snap-fit ​​groove 211, forming a two-way constraint. This ensures that the support device 100 remains rigidly connected to the frame 200 during long-term, multi-station vehicle transfer, completely preventing it from falling off and ensuring continuous operation of the production line.

[0043] In one embodiment of this utility model, one end of the snap-fit ​​seat 21 is hinged to the mounting end 11, and the other end of the snap-fit ​​seat 21 is provided with a claw 23, which is used to hold the support rod 10.

[0044] Specifically, such as Figure 2 As shown, one end of the snap-fit ​​seat 21 is hinged to the mounting end 11, and the other end has a clamp 23. When the engine hood support device 100 of the vehicle provided by this utility model is needed, the snap-fit ​​seat 21 can rotate relative to the mounting end 11 around the hinge point, and the support rod 10 changes its tilt angle accordingly to adapt to different opening heights of the engine hood or to avoid surrounding parts; when the angle is adjusted to the correct position, the clamp 23 clamps the support rod 10, and the snap-fit ​​seat 21 and the support rod 10 are rigidly locked together, ensuring that the snap-fit ​​groove 211 and the frame 200 maintain a stable snap-fit ​​engagement. After the operation is completed, the clamp 23 is released, and the snap-fit ​​seat 21 can rotate again, allowing the support device 100 to fold and retract, reducing the space occupied.

[0045] In one embodiment of the present invention, the two ends of the support plug 121 are a connecting part and a free part, respectively. The connecting part is connected to the support end 12. An abutting ring plate 122 is provided on the outer periphery of the support plug 121 near the connecting part. The free part is used to insert into the first opening. The abutting ring plate 122 is used to abut against the bottom of the engine cover when the free part is inserted into the first opening.

[0046] Specifically, such as Figure 1As shown, the support plug 121 is divided into a connecting part and a free part. The connecting part is fixedly connected to the support end 12, and the free part is used to insert into the first opening at the bottom of the engine hood. When the free part enters the first opening, the abutment ring plate 122 surrounding the connecting part immediately fits against the bottom plane of the engine hood, forming an end face support, preventing the support plug 121 from going further in, thereby precisely limiting the opening height of the engine hood and distributing the load, avoiding stress concentration and deformation at the edge of the first opening. The abutment ring plate 122 and the support plug 121 are integrally formed, requiring no additional parts, with a simple structure and convenient manufacturing, which not only improves the reliability of installation and positioning, but also extends the service life of the engine hood and the first opening.

[0047] In one embodiment of this utility model, a handle 30 is also provided on the support rod 10, and the handle 30 is disposed between the support end 12 and the mounting end 11.

[0048] Specifically, the support rod 10 has a handle 30 integrally formed or welded between the support end 12 and the mounting end 11, and the handle 30 is ring-shaped. When using the engine hood support device 100 of the vehicle provided by this utility model, the operator can hold the handle 30 to carry, insert, remove, or adjust the support device 100 with one hand; the handle 30 is located in the middle section of the support rod 10, with a moderate lever arm, making it easy to carry and preventing interference with the engine hood or frame 200. The handle 30 is formed synchronously with the main body of the support rod 10, without increasing the number of parts, resulting in a simple structure, significantly shortening the disassembly and assembly time, and reducing labor intensity.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
