Description

Technical Field

[0001] The present invention relates to the technical field of vehicle maintenance equipment, and particularly relates to a stacked vehicle ramp. Background Art

[0002] Currently, many vehicle owners will inspect, perform daily maintenance, and repair their vehicles. To facilitate access to the bottom of the vehicle, they will lift the front or rear of the vehicle to provide a suitable working environment. Amateur auto mechanics and vehicle owners use various portable ramps for this purpose. These ramps are usually made of metal and have various configurations to enable the wheels to be driven onto the inclined part of the ramp and then rest on the wheel fixing area of the ramp.

[0003] There is a prior utility model patent with the publication number CN204228424U, which protects a portable small vehicle parking brake inspection ramp. A portable small vehicle parking brake inspection ramp includes a plurality of identical inspection platforms, which are changed into a plurality of small inspection platforms with the same slope as required by the inspection standard. The plurality of small inspection ramps are simultaneously placed under each wheel of the vehicle in the same direction (for the axle of a double-wheel vehicle, only one small inspection ramp needs to be placed under any one of the double wheels). Separate equivalent vehicle uphill parking inspections or downhill parking inspections are carried out.

[0004] In the above technical solution, since the existing vehicle ramps are usually made of metal to be able to carry the vehicle, they are relatively heavy and occupy a large space, and are not convenient for users to move. Summary of the Invention

[0005] To solve the deficiencies of the prior art, the present invention provides a stacked vehicle ramp.

[0006] The technical solution of the present invention is as follows:

[0007] The present invention provides a stacked vehicle ramp, including a bottom frame. One end of the bottom frame is fixedly connected with an inclined plate. Side plates are fixedly provided on both sides of the bottom frame. The other end of the bottom frame is fixedly connected with a rear plate. The inclined plate is inclined upward from the end of the bottom frame away from the rear plate to the other end. The higher end of the inclined plate is fixedly connected with a horizontally arranged top plate. The inclined plate, the top plate, and the rear plate are all fixedly connected between the two side plates. The end of the top plate away from the inclined plate is fixedly connected to the rear plate;

[0008] The inclined plate is provided with a first left groove and a first right groove, both of which are arranged along the length direction of the inclined plate. The top plate is provided with a second left groove and a second right groove, both of which are arranged along the length direction of the top plate. The first left groove communicates with the second left groove, and the first right groove communicates with the second right groove. The bottoms of the first left groove, the first right groove, the second left groove, and the second right groove are coplanar with the bottom of the bottom frame;

[0009] Both the first left groove and the second left groove are formed with left arc-shaped depressions, and right arc-shaped depressions are formed at positions corresponding to the left arc-shaped depressions in the first right groove and the second right groove. The cross-sectional areas of the first left groove (21), the first right groove (22), the second left groove (41), the second right groove (42), the left arc-shaped depression (211), and the right arc-shaped depression (221) gradually increase from the bottom to the top. The convex surface of the left arc-shaped depression faces the right arc-shaped depression, and the convex surface of the right arc-shaped depression faces the left arc-shaped depression. Multiple arc-shaped grooves are provided on both side plates, and the convex surfaces of the arc-shaped grooves all face the other side plate.

[0010] The beneficial effects achieved by the present invention are as follows: The left arc-shaped depression, the right arc-shaped depression, and the arc-shaped grooves can all effectively improve the rigidity of the vehicle ramp. The first left groove, the first right groove, the second left groove, and the second right groove increase the contact area between the vehicle ramp and the ground, thereby increasing the strength of the vehicle ramp. The inner arch structure formed by the left arc-shaped depression and the right arc-shaped depression can distribute the lateral load and generate internal stress to offset the horizontal shear force generated during the movement and stationary state of the vehicle, further increasing the strength of the vehicle ramp. The longitudinal sections of the first left groove, the first right groove, the second left groove, the second right groove, the left arc-shaped depression, and the right arc-shaped depression are inverted triangles to increase the dispersion effect of the upward pressure on the vehicle ramp, further increasing the strength of the vehicle ramp. This enables the vehicle ramp of the present application to use lightweight materials such as plastics and still be sufficient to support the vehicle, facilitating the user to carry and move it. And because the bottom of the vehicle ramp is hollow, they can be stacked on top of each other, making it convenient to carry multiple vehicle ramps in the vehicle at the same time without occupying too much space.

[0011] Furthermore, a rear protrusion is fixedly connected to the top of the rear plate. The height of the rear protrusion exceeds that of the top plate, and a rear inclined surface is provided on the side of the rear protrusion close to the top plate. The rear inclined surface is inclined upward from the side close to the top plate to the other side. The rear plate is provided with a third left groove and a third right groove. Both the third left groove and the third right groove are arranged vertically. The second left groove is communicated with the third left groove, and the second right groove is communicated with the third right groove. The third left groove is inclined from the end close to the top plate to the other end away from the third right groove, and the third right groove is inclined from the end close to the top plate to the other end away from the third left groove. Rear arc-shaped depressions are provided at positions on the rear plate close to the third left groove and the third right groove, and the convex surfaces of the rear arc-shaped depressions face the top plate.

[0012] Through the above solution, when the vehicle drives onto the vehicle ramp, the rear protrusion will block the wheels, reducing the possibility of the wheels passing over the vehicle ramp and increasing the use safety. And the third left groove and the third right groove are distributed in a Y shape on the vehicle ramp and are communicated with the second left groove and the second right groove. When the wheels contact the rear inclined surface, the third left groove and the third right groove can effectively eliminate the pressure of the wheels, further increasing the strength of the vehicle ramp.

[0013] Furthermore, arc-shaped plates are fixedly connected to both the arc-shaped groove and the bottom of the rear arc-shaped depression, and the arc-shaped plates are fixedly connected to the bottom frame.

[0014] With the above solution, the arc-shaped plates increase the contact area between the vehicle ramp and the ground. At the same time, the arc-shaped plates are beneficial to the shaping of the left arc-shaped depression, the right arc-shaped depression, and the rear arc-shaped depression, further increasing the strength of the vehicle ramp.

[0015] Furthermore, a plurality of first anti-slip blocks are fixedly connected to the inclined plate near the lower end. Second anti-slip blocks are fixedly connected to the bottom of the arc-shaped plate directly below the top plate and at the positions of the second left groove and the second right groove close to the rear plate. First anti-slip patterns are fixedly provided at the bottoms of the first anti-slip blocks and the second anti-slip blocks.

[0016] With the above solution, the friction between the vehicle ramp and the ground is effectively enhanced, the wear on the bottom of the product is reduced, and the product life is increased. When the vehicle tire is on the inclined plate, the first anti-slip block will be stressed to prevent the vehicle ramp from sliding. When the vehicle tire moves to the top plate, the second anti-slip block will be stressed to prevent the vehicle ramp from sliding. When the vehicle continues to move and the tire reaches the rear plate, the second anti-slip blocks at the positions of the second left groove and the second right groove close to the rear plate will be stressed to prevent the vehicle ramp from sliding.

[0017] Furthermore, the widths of the first left groove, the first right groove, the second left groove, the second right groove, the third left groove, and the third right groove gradually decrease from the top to the bottom. A left support plate is fixedly connected to the bottom of the third left groove, and the left support plate is fixedly connected to the second left groove. The inclination direction of the left support plate is the same as the inclination direction of the third left groove. A right support plate is fixedly connected to the bottom of the third right groove, and the right support plate is fixedly connected to the second right groove. The inclination direction of the right support plate is the same as the inclination direction of the third right groove. The bottoms of the left support plate and the right support plate are coplanar with the bottom surface of the bottom frame.

[0018] With the above solution, the tapered structure with a narrow bottom and a wide top not only increases the strength but also makes it easier to stack the vehicle ramps. The left support plate and the right support plate can effectively extend the third left groove and the third right groove, increasing the strength of the rear part of the vehicle ramp.

[0019] Furthermore, drainage depressions are provided at the bottoms of the first left groove, the first right groove, the second left groove, and the second right groove. Drainage through grooves are provided at the positions corresponding to the drainage depressions at the bottoms of the first left groove, the first right groove, the second left groove, and the second right groove.

[0020] With the above solution, after water enters the first left groove, the first right groove, the second left groove, or the second right groove, the water can be discharged through the drainage through grooves and will not accumulate inside. The drainage depressions are used to ensure a certain height between the drainage through grooves and the ground, ensuring smooth drainage.

[0021] Furthermore, at the positions corresponding to the drainage depressions at the bottoms of the first left groove, the first right groove, the second left groove, and the second right groove, there are multiple drainage reinforcing ribs, and all the drainage reinforcing ribs are arranged along the width direction of the bottom frame.

[0022] Through the above solution, the drainage reinforcing ribs make up for the weakness in the strength of the bottom of the vehicle ramp caused by the drainage depression, ensuring the strength of the bottom of the vehicle ramp.

[0023] Furthermore, on the outer sides of the second left groove and the second right groove, and at the bottoms of the inclined plate and the top plate, there are multiple transverse reinforcing ribs fixedly connected, and at the bottoms of the inclined plate and the top plate, there are multiple longitudinal reinforcing ribs fixedly connected. The transverse reinforcing ribs are all arranged along the width direction of the bottom frame, the longitudinal reinforcing ribs are all arranged along the length direction of the bottom frame, and the bottom surfaces of the transverse reinforcing ribs and the longitudinal reinforcing ribs are higher than the height of the bottom frame.

[0024] Through the above solution, while increasing the strength of the vehicle ramp, the transverse reinforcing ribs and the longitudinal reinforcing ribs will not affect the stacking of the vehicle ramp due to their relatively high height.

[0025] Furthermore, circular reinforcing ribs are fixedly connected to the bottoms of the multiple transverse reinforcing ribs.

[0026] Through the above solution, the circular reinforcing ribs are used to strengthen the strength of the key - stressed transverse reinforcing ribs.

[0027] Furthermore, on both sides of the inclined plate, there are first side rails fixedly connected, and on both sides of the top plate, there are second side rails fixedly connected. The first side rails are all arranged along the length direction of the inclined plate, the second side rails are all arranged along the length direction of the top plate, the first side rails are higher than the upper surface of the inclined plate, and the second side rails are higher than the upper surface of the top plate.

[0028] Through the above solution, the first side rails and the second side rails are used to prevent the wheels on the vehicle ramp from falling off to both sides of the vehicle ramp.

[0029] A stacked vehicle ramp of the present invention has the following advantages:

[0030] 1. The left arc - shaped depression, the right arc - shaped depression, and the arc - shaped groove can all effectively improve the rigidity of the vehicle ramp. The first left groove, the first right groove, the second left groove, and the second right groove increase the contact area between the vehicle ramp and the ground, thereby increasing the strength of the vehicle ramp. The inner arch - shaped structure formed by the left arc - shaped depression and the right arc - shaped depression can distribute the lateral load, generating internal stress to offset the horizontal shear force generated during the movement and static state of the vehicle, further increasing the strength of the vehicle ramp. This enables the vehicle ramp of the present application to use lightweight materials such as plastic and still be sufficient to support the vehicle, facilitating the user to carry and move it. And because the bottom of the vehicle ramp is hollow, they can be stacked on top of each other, making it convenient to carry multiple vehicle ramps in the vehicle at the same time without taking up too much space.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0040] The present invention provides a stacked vehicle ramp, as Figure 1 and Figure 2 shown, which includes a bottom frame 1. One end of the bottom frame 1 is fixedly connected to an inclined plate 2. Side plates 3 are fixedly provided on both sides of the bottom frame 1. The other end of the bottom frame 1 is fixedly connected to a rear plate 5. The inclined plate 2 is inclined upward from the end of the bottom frame 1 far from the rear plate 5 to the other end. The higher end of the inclined plate 2 is fixedly connected to a horizontally arranged top plate 4. The side plates 3 are both inclined downward from the side close to the top plate 4 to the other side. The inclined plate 2, the top plate 4, and the rear plate 5 are all fixedly connected between the two side plates 3. The end of the top plate 4 far from the inclined plate 2 is fixedly connected to the rear plate 5. The vehicle ramp as a whole is made of plastic.

[0041] As Figure 1 and Figure 2 shown, second anti-slip patterns 29 are fixedly connected to both the inclined plate 2 and the top plate 4. The second anti-slip patterns 29 are used to increase the friction between the vehicle ramp and the wheels. A connection through hole 28 is opened at a position close to the lower end of the inclined surface. The connection through hole 28 can be used to install fasteners to fix the vehicle ramp, or straps, ropes, etc. can pass through the connection through hole 28 to tie multiple vehicle ramps together or lift the vehicle ramp. Handle grooves 27 are opened on both side plates 3. The handle grooves 27 facilitate the user to move the vehicle ramp.

[0042] As Figure 1 and Figure 2 shown, first side rails 26 are fixedly connected to both sides of the inclined plate 2, and second side rails 43 are fixedly connected to both sides of the top plate 4. The first side rails 26 are all arranged along the length direction of the inclined plate 2, and the second side rails 43 are all arranged along the length direction of the top plate 4. The first side rails 26 protrude above the upper surface of the inclined plate 2, and the second side rails 43 protrude above the upper surface of the top plate 4. The first side rails 26 and the second side rails 43 are used to prevent the wheels on the vehicle ramp from falling off to both sides of the vehicle ramp.

[0043] As Figure 1 and Figure 2As shown in the figure, the inclined plate 2 is provided with a first left groove 21 and a first right groove 22. Both the first left groove 21 and the first right groove 22 are arranged along the length direction of the inclined plate 2. The top plate 4 is provided with a second left groove 41 and a second right groove 42. Both the second left groove 41 and the second right groove 42 are arranged along the length direction of the top plate 4. The first left groove 21 communicates with the second left groove 41, and the first right groove 22 communicates with the second right groove 42. The bottoms of the first left groove 21, the first right groove 22, the second left groove 41 and the second right groove 42 are coplanar with the bottom of the bottom frame 1. The rear plate 5 is provided with a third left groove 51 and a third right groove 52. Both the third left groove 51 and the third right groove 52 are arranged vertically. The second left groove 41 communicates with the third left groove 51, and the second right groove 42 communicates with the third right groove 52. The third left groove 51 is inclined from one end close to the top plate 4 to the other end away from the third right groove 52, and the third right groove 52 is inclined from one end close to the top plate 4 to the other end away from the third left groove 51. The first left groove 21, the second left groove 41 and the third left groove 51 communicate with each other, and the first right groove 22, the second right groove 42 and the third right groove 52 communicate with each other, so that two continuous grooves are formed on the vehicle ramp, which is beneficial to the structural stability and production and processing. The first left groove 21, the first right groove 22, the second left groove 41 and the second right groove 42 increase the contact area between the vehicle ramp and the ground, thereby increasing the strength of the vehicle ramp.

[0044] As Figure 1 and Figure 2 shown in the figure, both the first left groove 21 and the second left groove 41 are formed with a left arc-shaped depression 211, and corresponding to the position of the left arc-shaped depression 211, both the first right groove 22 and the second right groove 42 are formed with a right arc-shaped depression 221. The cross-sectional areas of the left arc-shaped depression (211) and the right arc-shaped depression (221) gradually increase from the bottom to the top. The convex surface of the left arc-shaped depression 211 faces the right arc-shaped depression 221, and the convex surface of the right arc-shaped depression 221 faces the left arc-shaped depression 211. The two side plates 3 are provided with a plurality of arc-shaped grooves 31, and the convex surfaces of the arc-shaped grooves 31 all face the other side plate 3. The rear plate 5 is provided with a rear arc-shaped depression 54 at positions close to the third left groove 51 and the third right groove 52, and the convex surface of the rear arc-shaped depression 54 faces the top plate 4. The left arc-shaped depression 211, the right arc-shaped depression 221 and the arc-shaped grooves 31 can all effectively improve the rigidity of the vehicle ramp. The inner arch structure formed by the left arc-shaped depression 211 and the right arc-shaped depression 221 can share the lateral load and generate internal stress to offset the horizontal shear force generated in the moving and static states of the vehicle, further increasing the strength of the vehicle ramp.

[0045] As Figure 3 and Figure 4As shown, the widths of the first left groove 21, the first right groove 22, the second left groove 41, the second right groove 42, the third left groove 51 and the third right groove 52 gradually decrease from top to bottom. A left support plate 511 is fixedly connected to the bottom of the third left groove 51. The left support plate 511 is fixedly connected to the second left groove 41. The inclination direction of the left support plate 511 is the same as that of the third left groove 51. A right support plate 521 is fixedly connected to the bottom of the third right groove 52. The right support plate 521 is fixedly connected to the second right groove 42. The inclination direction of the right support plate 521 is the same as that of the third right groove 52. The ground surfaces of the left support plate 511 and the right support plate 521 are coplanar with the bottom surface of the bottom frame 1. The tapered structure with a narrow bottom and a wide top not only increases the strength but also makes it easier to stack the vehicle ramps. The left support plate 511 and the right support plate 521 can effectively extend the third left groove 51 and the third right groove 52, increasing the strength of the rear part of the vehicle ramp.

[0046] As Figure 1 and Figure 2 shown, arc-shaped plates 32 are fixedly connected to the bottoms of the arc-shaped groove 31 and the rear arc-shaped recess 54. The arc-shaped plates 32 are fixedly connected to the bottom frame 1. The arc-shaped plates 32 increase the contact area between the vehicle ramp and the ground. At the same time, the arc-shaped plates 32 are beneficial to the shaping of the arc-shaped groove 31 and the rear arc-shaped recess 54, further increasing the strength of the vehicle ramp.

[0047] As Figure 3 shown, a rear protrusion 53 is fixedly connected to the top of the rear plate 5. The height of the rear protrusion 53 exceeds that of the top plate 4. A rear inclined surface 531 is provided on one side of the rear protrusion 53 close to the top plate 4. The rear inclined surface 531 is inclined upward from the side close to the top plate � to the other side. When a vehicle drives onto the vehicle ramp, the rear protrusion 53 will block the wheels, reducing the possibility of the wheels passing over the vehicle ramp and increasing the use safety.

[0048] As Figure 5 shown, a plurality of first anti-slip blocks 23 are fixedly connected to the inclined surface near the lower end. Arc-shaped plates 32 are fixedly connected to the bottoms of the arc-shaped plates 32 directly below the top plate 4, and second anti-slip blocks 212 are fixedly connected to the positions of the second left groove 41 and the second right groove 42 close to the rear plate (5). First anti-slip patterns 231 are fixedly provided at the bottoms of the first anti-slip blocks 23 and the second anti-slip blocks 212. The first anti-slip blocks 23 effectively enhance the friction between the vehicle ramp and the ground, reduce the wear on the bottom of the product, and increase the service life of the product.

[0049] As Figure 5As shown, drainage depressions 213 are provided at the bottoms of the first left groove 21, the first right groove 22, the second left groove 41, and the second right groove 42, and drainage through grooves 214 are provided at positions corresponding to the drainage depressions 213 at the bottoms of the first left groove 21, the first right groove 22, the second left groove 41, and the second right groove 42. At positions corresponding to the drainage depressions 213 at the bottoms of the first left groove 21, the first right groove 22, the second left groove 41, and the second right groove 42, a plurality of drainage strengthening ribs 215 are provided, and the drainage strengthening ribs 215 are all arranged along the width direction of the bottom frame 1. After water enters the first left groove 21, the first right groove 22, the second left groove 41, or the second right groove 42, the water can be discharged through the drainage through grooves 214 and will not accumulate inside. The drainage depression 213 is used to ensure that there is a certain height between the drainage through groove 214 and the ground to ensure smooth drainage. The drainage strengthening ribs 215 make up for the shortcoming of the weakened strength of the bottom of the vehicle ramp brought by the drainage depression 213 and ensure the strength of the bottom of the vehicle ramp.

[0050] As Figure 5 [[ID=P5]]As shown, a plurality of transverse strengthening ribs 24 are fixedly connected to the outsides of the second left groove 41 and the second right groove 42, and the bottoms of the inclined plate 2 and the top plate 4. A plurality of longitudinal strengthening ribs 25 are fixedly connected to the bottoms of the inclined plate 2 and the top plate 4. The transverse strengthening ribs 24 are all arranged along the width direction of the bottom frame 1, and the longitudinal strengthening ribs 25 are all arranged along the length direction of the bottom frame 1. The bottom surfaces of the transverse strengthening ribs 24 and the longitudinal strengthening ribs 25 are higher than the height of the bottom frame 1. A circular strengthening rib 241 is fixedly connected to the bottoms of the plurality of transverse strengthening ribs 24. The transverse strengthening ribs 24 and the longitudinal strengthening ribs 25 increase the strength of the vehicle ramp. At the same time, due to their relatively high height, they will not affect the stacking of the vehicle ramp. The circular strengthening rib 241 is used to strengthen the strength of the transverse strengthening rib 24 that bears the key load.

[0051] The implementation principle of the stacked vehicle ramp provided by the present invention is as follows: The left arc-shaped depression 211, the right arc-shaped depression 221, and the arc-shaped groove 31 can all effectively improve the rigidity of the vehicle ramp. The first left groove 21, the first right groove 22, the second left groove 41, and the second right groove 42 increase the contact area between the vehicle ramp and the ground, thereby increasing the strength of the vehicle ramp. The inner arch structure formed by the left arc-shaped depression 211 and the right arc-shaped depression 221 can share the lateral load and generate internal stress to offset the horizontal shear force generated during the movement and static state of the vehicle, further increasing the strength of the vehicle ramp. This enables the vehicle ramp of the present application to use lightweight materials such as plastics and still be sufficient to support the vehicle, facilitating the user to carry and move it. And because the bottom of the vehicle ramp is hollow, they can be stacked on top of each other, making it convenient to carry multiple vehicle ramps in the vehicle at the same time without occupying too much space.

[0052] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
