[0026] The present invention will be further described below with reference to the accompanying drawings.
[0027] This utility model provides an anti-rollover device that can prevent vehicles from rolling away during parking, thus avoiding safety hazards during vehicle parking. It is also convenient to use and has a simple structure, reducing processing and manufacturing costs.
[0028] Figure 1 This is a schematic diagram of the anti-rollover device in use according to one embodiment of this application. Figure 1 As shown, this application embodiment provides an anti-rollover device 1000. The anti-rollover device 1000 includes a fixed base 100, a limiting member 200, and a support assembly 300. One end of the limiting member 200 is rotatably connected to the fixed base 100. Multiple limiting portions 210 are provided on the side of the limiting member 200 facing the fixed base 100. The multiple limiting portions 210 are sequentially spaced along a direction perpendicular to the rotation axis of the limiting member 200. The support assembly 300 includes a support rod 310. The support rod 310 includes a first end and a second end relative to each other along its own length. The first end is rotatably connected to the fixed base 100, and the rotation axis of the support rod 310 is parallel to the rotation axis of the limiting member 200. The second end can be individually connected to each limiting portion 210.
[0029] It should be noted that the limiting member 200 has multiple limiting parts 210 on the side facing the fixed base 100, and these limiting parts 210 are distributed sequentially at intervals along the direction perpendicular to the rotation axis of the limiting member 200. This arrangement allows the second end of the support rod 310 to be connected to different limiting parts 210 as needed, thereby adjusting the position and angle of the limiting member 200.
[0030] The second end of the support rod 310 is connected to the limiting part 210. The second end of the support rod 310 can abut against the limiting part 210, or the second end of the support rod 310 can be detachably connected by fasteners such as bolts, screws or connecting pins. As long as the support rod 310 can support the limiting part 200 after it is connected to the limiting part 210, it is acceptable.
[0031] One end of the limiting member 200 is rotatably connected to the fixed base 100. The limiting member 200 and the fixed base can be hinged together or rotatably connected through a bearing or universal joint.
[0032] The fixed base 100 and the limiting component 200 can be plate parts or a frame made of multiple steel profiles welded together.
[0033] According to the embodiment of this application, the anti-rollover device 1000, when it is necessary to fix the vehicle, rotates the limiting member 200 so that the limiting member 200 can rotate relative to the fixing seat 100 around the rotation axis. After rotating to a suitable angle, the second end of the support rod 310 is connected to the appropriate limiting part 210 on the limiting member 200. Through the supporting action of the support rod 310, the limiting member 200 can limit the wheels of the vehicle to prevent the vehicle from rolling away, avoid safety hazards during vehicle parking, and is convenient to use and has a simple structure, reducing processing and manufacturing costs.
[0034] like Figure 1 As shown, in some embodiments, the support component 300 further includes a connecting component 320. The connecting component 320 is connected to the second end and to the limiting portion 210.
[0035] It should be noted that when the limiting part 210 of the limiting member 200 is a limiting block, the connecting component 320 can be a sleeve that is connected to the second end of the support rod 310 and cooperates with the limiting block. The sleeve is sleeved on the outside of the limiting block to limit the limiting block. Of course, the limiting part 210 can also be a limiting member 200 with a through hole. In this case, the connecting component 320 includes a connecting end and a fastener. The connecting end is connected to the second end of the support rod 310 and is also provided with a through hole. The fastener is connected to the through hole of the limiting block and the through hole of the connecting end respectively. The fastener can be a pin or a bolt and nut, etc.
[0036] In this embodiment, the second end of the support rod 310 is connected to the limiting part 210 of the limiting member 200 through the connecting component 320 to support the limiting member 200, thereby enhancing the connection strength, stability and flexibility between the support rod 310 and the limiting part 210.
[0037] like Figure 1 As shown, in some embodiments, the connecting assembly 320 includes a connecting portion 321. The connecting portion 321 is fixedly connected to the second end and is hook-shaped. The limiting portion 210 includes a retaining ring 211. The retaining ring 211 is fixedly connected to the limiting member 200. The connecting portion 321 and the retaining ring 211 are engaged and connected.
[0038] In this embodiment, the limiting part 210 includes a retaining ring 211. The connecting part 321 of the connecting assembly 320 is fixedly connected to the second end of the support rod 310, and the connecting part 321 is hook-shaped. When it is necessary to connect the support rod 310 to the limiting part 210, the user only needs to insert the hook-shaped part of the connecting part 321 into the retaining ring 211, which will form a stable connection between the support rod 310 and the limiting member 200, thereby preventing the vehicle from slipping. The design of the hook-shaped connecting part 321 and the retaining ring 211 makes the connection process between the support rod 310 and the limiting member 200 simpler and faster. The user can connect the support rod 310 to the limiting part 210 without complicated operations or tools, thereby improving work efficiency. At the same time, since the design of the connecting part 321 and the retaining ring 211 is relatively simple and easy to inspect, maintenance is also more convenient. The user can easily check the wear of the connecting part 321 and the retaining ring 211 and replace or repair them when necessary.
[0039] like Figure 1 As shown, in some embodiments, the anti-rollover device 1000 further includes a first support member 400. The first support member 400 is disposed in the receiving groove 110, and the first support member 400 abuts against the support rod 310 in the thickness direction of the fixed seat 100.
[0040] In this embodiment, the first support member 400 provides support for the support rod 310 when it is placed in the receiving groove 110.
[0041] like Figure 1 As shown, in some embodiments, the anti-rollover device 1000 further includes a second support member 500. The second support member 500 is disposed on the side of the fixed base 100 facing the limiting member 200. The second support member 500 and the limiting member 200 abut against each other in the thickness direction of the fixed base 100.
[0042] In this embodiment, when the anti-rollover device 1000 is not in use, the limiting member 200 and the fixed seat 100 rotate to a stacked state, and the second support member 500 can support the limiting member 200 stacked on the fixed seat 100.
[0043] like Figure 1 As shown, in some embodiments, an anti-slip component 220 is provided on the side of the limiting member 200 opposite to the fixing base 100. The anti-slip component 220 includes an anti-slip element 221, which is connected to the limiting member 200.
[0044] It should be noted that the anti-slip component 221 can be an anti-slip mat or an anti-slip protrusion provided on the limiting component 200, etc.
[0045] In this embodiment, when the anti-rollover device 1000 is in use, the limiting member 200 rotates to a suitable angle, and the support rod 310 supports the limiting member 200. The side of the limiting member 200 away from the fixed seat 100 abuts against the wheel of the vehicle. The anti-slip member 221 in the anti-slip assembly 220 on the side of the limiting member 200 away from the fixed seat 100 can effectively increase the friction between the contact surface with the vehicle wheel and play an anti-slip role on the vehicle wheel, thereby preventing the device from sliding or displacing.
[0046] like Figure 1 As shown, in some embodiments, the anti-slip element 221 is an anti-slip pad. The anti-slip assembly 220 also includes an adhesive element 222, through which the anti-slip pad and the limiting element 200 are connected.
[0047] In this embodiment, the anti-slip component 221 is an anti-slip pad, which is bonded to the limiting component 200 by the adhesive component 222 to ensure a tight connection and coordinated operation between the two, while also facilitating the replacement of the anti-slip pad.
[0048] In some optional embodiments, the adhesive component 222 includes a first adhesive component 222 and a second adhesive component 222 that cooperate with each other. The first adhesive component 222 is fixedly connected to the anti-slip mat, and the second adhesive component 222 is fixedly connected to the limiting component 200. The anti-slip mat is connected to the limiting component 200 through the adhesion of the first adhesive component 222 and the second adhesive component 222. When the anti-slip mat needs to be replaced, simply separate the first adhesive component 222 from the second adhesive component 222, and then adhere a new anti-slip component 221 with the first adhesive component 222 to the second adhesive component 222, thus facilitating the replacement of the anti-slip mat.
[0049] like Figure 1 As shown, in some embodiments, the limiting member 200 further includes a mounting groove 230. The anti-slip component 220 is disposed in the mounting groove 230.
[0050] In this embodiment, the anti-slip component 220 is disposed in the mounting groove 230 to prevent it from falling off or shifting during use, and to ensure that the anti-slip component 220 can be firmly fixed on the limiting member 200.
[0051] like Figure 1 As shown, in some optional embodiments, a shock absorber 130 is also provided on the side of the fixed base 100 opposite to the limiting member 200. The shock absorber 130 is connected to the fixed base 100. In this embodiment, the shock absorber 130 can play a role in shock absorption and protection of the fixed base 100, improving the safety of the device.
[0052] like Figure 1-2As shown, in some embodiments, both the fixing base 100 and the limiting member 200 are plate parts. The fixing base 100 is provided with a receiving groove 110 with an opening facing the limiting member 200 on the side facing the limiting member 200, and the support rod 310 is disposed in the receiving groove 110.
[0053] In this embodiment, the fixing base 100 is a plate. The side of the fixing base 100 facing the limiting member 200 is provided with a receiving groove 110 with an opening facing the limiting member 200. The support rod 310 is disposed in the receiving groove 110. When the anti-slip device 1000 is not in use, the two plates, the fixing base 100 and the limiting member 200, can be rotated to stack on each other. At this time, the support rod 310 does not need to support the limiting member 200. The support rod 310 can be stored in the receiving groove 110, which simplifies the structure of the device and improves its overall performance and practicality.
[0054] like Figure 3 As shown, in some embodiments, the mounting base 100 further includes multiple fastening components 120, each of which is connected to the mounting base 100. The mounting base 100 is securely fixed to a predetermined position by the fastening components 120, ensuring that the anti-slip device 1000 does not loosen or shift during use. The number and distribution of the fastening components 120 are typically determined based on the size and shape of the mounting base 100 and the load it needs to withstand. For example, placing fastening components 120 at the four corners or edges of the mounting base 100 ensures stable support for the mounting base 100 in all directions.
[0055] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
