Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile protection, in particular to an engine protection device. BACKGROUND

[0002] At present, in common automobile structure, the bottom of the engine is directly exposed outside the vehicle body, and the phenomenon of dragging the bottom is prone to occur when the vehicle encounters obstacles during driving, which causes damage to the bottom of the engine and its accessories, especially for vehicles running on complex off-road conditions, such as mine vehicles and engineering vehicles, the phenomenon of dragging the bottom is more common. In the prior art, engine protection plates are often added to protect the engine, but the existing engine protection plates mostly adopt a closed structure to shield the engine to achieve protection. After the protection plate is damaged and deformed, it is easy to collide with the engine oil pan and its accessories, the protection effect is poor, and the existing engine protection plate also has the problems of shielding the engine, which is not convenient for the maintenance of the bottom of the vehicle, and easy to accumulate sand or debris, which is not convenient to clean. SUMMARY

[0003] The present application aims to at least solve one of the problems in the prior art or related art.

[0004] To this end, the purpose of the present application is to provide an engine protection device.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present application provides an engine protection device, comprising: a protection plate arranged below the vehicle body carrying the engine, and the protection plate is arranged on one side of the engine, both ends of the protection plate extend towards the engine, and the protection plate forms a non-zero first included angle, so as to guide the obstacles in the direction of travel of the vehicle body to both sides of the engine through the protection plate.

[0006] According to the engine protection device of the present application, the protection plate is arranged below the vehicle body carrying the engine to protect the engine. Specifically, the protection plate is arranged on one side of the engine, and both ends of the protection plate extend towards the engine, so that both ends of the protection plate form a non-zero first included angle, i.e. the opening on the side of the engine gradually increases, so as to block the obstacles in the direction of travel of the vehicle body through the opening structure of the protection plate, and further guide the obstacles to both sides of the engine to prevent the obstacles from colliding with the engine, thereby protecting the engine and effectively reducing the cost of vehicle use. In addition, the protection plate is arranged on one side of the engine, so that the bottom of the engine is not shielded, which does not affect the maintenance operation of the bottom of the vehicle, and also does not cause the protection plate to accumulate sand or debris, which is difficult to clean and even causes the engine to be bumped. The protection plate can be arranged on the front side or the rear side of the engine along the length direction of the vehicle body, of course, it can also be arranged at a certain angle with the length direction of the vehicle body, and multiple protection plates can also be arranged in different directions to enhance the protection performance.

[0007] Optionally, the first included angle ranges from 30° to 180°, and more particularly, the first included angle ranges from 60° to 150°.

[0008] It should be emphasized that the protective plate can be a V-shaped structure with both ends extending towards the engine, or a trapezoidal structure with both ends of the protective plate extending towards the engine, or a U-shaped structure or other structure that can guide the obstacles to the ends of the engine.

[0009] It should be noted that the size of the engine protection device in the vertical direction is smaller than the minimum ground clearance of the vehicle body (referring to the distance between the lowest point of the vehicle excluding the tire and the supporting plane when the vehicle is fully loaded and stationary), so as to prevent the engine protection device from contacting the ground and affecting the normal driving of the vehicle; the lowest point of the protective plate is lower than the lowest point of the engine, so as to ensure that the obstacles with a height lower than the lowest point of the protective plate cannot directly contact the engine; the size of the engine protection device along the width direction of the vehicle body is smaller than or equal to the maximum width of the vehicle body, so as to prevent the engine protection device from colliding with external objects or vehicles outside the vehicle body.

[0010] In addition, the engine protection device in the above technical solution provided by the present application can further have the following additional technical features:

[0011] In the above technical solution, the mounting plate is fixedly connected to the top of the protective plate, and the mounting plate can be detachably connected to the bottom of the vehicle body.

[0012] In this technical solution, the mounting plate that can be detachably connected to the bottom of the vehicle body is provided, and the mounting plate is fixedly connected to the top of the protective plate, so that the protective plate can be detachably connected with the vehicle body, thereby facilitating the disassembly and assembly of the engine protection device; at the same time, the fixed connection of the mounting plate and the protective plate can strengthen the strength of the protective plate and reduce the possibility of deformation and damage of the protective plate after being impacted, thereby enhancing the protection performance of the engine protection device. The fixed connection includes but is not limited to welding, riveting, and bolt connection.

[0013] Further, the end of the protective plate away from the mounting plate extends obliquely towards the engine, and a second included angle is formed between the protective plate and the mounting plate.

[0014] In the technical scheme, the end of the protection plate away from the mounting plate is inclined towards the engine, and the second included angle is formed between the protection plate and the mounting plate, so that the obstacle can be extruded and compacted by the inclined structure of the protection plate, the height of the obstacle is reduced, and the possibility of collision with the engine is reduced, and the sand or debris on the protection plate can be prevented from accumulating to affect the guiding effect of the protection plate. It can be understood that in general off-road conditions, especially in the road conditions where mine vehicles often travel, the ground is relatively soft, and when the vehicle encounters hard obstacles such as stones, the obstacles can be extruded below the ground by the inclined structure of the protection plate, or when some relatively soft obstacles are encountered, the obstacles can be crushed by the inclined structure of the protection plate.

[0015] Optionally, the second included angle ranges from 0° to 90°, and more particularly, the second included angle ranges from 45° to 75°.

[0016] In the above technical scheme, the engine protection device further comprises: at least one vertical rib plate arranged on the side of the protection plate facing the engine, and each vertical rib plate is fixedly connected to the mounting plate and the protection plate at the top end and one side end, respectively.

[0017] In the technical scheme, at least one vertical rib plate is arranged on the side of the protection plate facing the engine to strengthen the strength of the protection plate. Specifically, the bottom end of each vertical rib plate is fixedly connected to the mounting plate, and one side end of each vertical rib plate is fixedly connected to the protection plate to support the protection plate when the protection plate is stressed, thereby reducing the possibility of deformation and bending of the protection plate. The fixed connection includes but is not limited to welding, riveting, and bolt connection.

[0018] Further, the number of vertical rib plates is multiple, each vertical rib plate is arranged perpendicularly to the mounting plate, and the vertical rib plates are arranged perpendicularly to the protection plate, and the multiple vertical rib plates are symmetrically arranged in the extension direction of the protection plate, wherein the number of vertical rib plates is less than or equal to 26.

[0019] In the technical scheme, multiple vertical rib plates are arranged on the side of the protection plate facing the engine, and each vertical rib plate is arranged perpendicularly to the mounting plate and the protection plate to further strengthen the strength of the protection plate. The multiple vertical rib plates are symmetrically arranged in the extension direction of the protection plate to make the stress of the protection plate more uniform when the protection plate collides with the obstacle. By limiting the number of vertical rib plates to be less than or equal to 26, the overall weight of the engine protection device can be reduced, and the processing complexity and cost can be reduced.

[0020] In the above technical scheme, the protection plate comprises: a first guide plate and a second guide plate, one end of the first guide plate facing the inner side of the vehicle body abuts against one end of the second guide plate facing the inner side of the vehicle body, and a first included angle is formed between the first guide plate and the second guide plate.

[0021] In the technical scheme, the first guide plate and the second guide plate of the protection plate abut against each other at one end of the first guide plate towards the inner side of the vehicle body and one end of the second guide plate towards the inner side of the vehicle body, so that there is no opening in the extension direction of the protection plate, to prevent obstacles from passing through the opening and colliding with the bottom of the engine; a first included angle is formed between the first guide plate and the second guide plate, so that the protection plate as a whole forms a V-shaped structure, and the opening side of the V-shaped structure faces the engine, to intercept obstacles in the advancing direction by the first guide plate and the second guide plate, and guide the obstacles to the two sides of the engine, to reduce the possibility of collision between the obstacles and the engine.

[0022] Further, the first guide plate and the second guide plate are fixedly connected.

[0023] In the technical scheme, the first guide plate and the second guide plate are fixedly connected, so that when obstacles collide with any position on the protection plate, the force received by the obstacles can be borne by the first guide plate and the second guide plate together, to further improve the overall strength of the protection plate and reduce the possibility of deformation of the first guide plate or the second guide plate due to force. The fixed connection includes but is not limited to welding, riveting, and bolt connection.

[0024] Further, the engine protection device further comprises a cross rib plate arranged on the side of the protection plate facing the engine and fixedly connected with the first guide plate and the second guide plate respectively.

[0025] In the technical scheme, the cross rib plate fixedly connected with the first guide plate and the second guide plate respectively is arranged on the side of the protection plate facing the engine, to further strengthen the connection strength between the first guide plate and the second guide plate and reduce the possibility of change in the angle of the first included angle due to force on the protection plate. It can be understood that when the first guide plate or the second guide plate is deformed due to collision force, the inclination angle of the first guide plate or the second guide plate towards the engine direction is likely to change, which further causes the second included angle to become smaller, thereby reducing the protection range and the guiding range of the protection plate. The fixed connection includes but is not limited to welding, riveting, and bolt connection.

[0026] Still further, the shape of one end of the cross rib plate towards the protection plate is adapted to the first included angle.

[0027] In the technical scheme, the cross rib plate is arranged to strengthen the strength of the first guide plate and the second guide plate; the shape of one end of the cross rib plate towards the protection plate is adapted to the first included angle, that is, one end of the cross rib plate towards the protection plate also forms a V-shaped structure adapted to the protection plate, and the connection area between the cross rib plate and the protection plate is increased, so that the force transmission is more uniform when the protection plate is collided, thereby improving the overall strength of the engine protection device.

[0028] In the above technical solution, the number of the protection plates is two, which are respectively arranged on the front side and the rear side of the engine along the running direction of the vehicle body.

[0029] In the technical solution, one protection plate is arranged on the front side and the rear side of the engine along the running direction of the vehicle body, so that the engine protection device can block and guide the obstacles when the vehicle encounters the obstacles during the forward or reverse movement, thereby expanding the protection range and further reducing the possibility of damage caused by the collision between the engine and the obstacles, which is beneficial to reduce the use cost and facilitate the use of the vehicle.

[0030] It should be noted that the number of the protection plates in the engine protection device is not limited to one or two, but can be multiple, and multiple protection plates can be arranged on the different sides of the engine, for example, on the left side and the right side of the engine, so as to further expand the protection range.
