[0030] Example 1

[0031] A specific embodiment of this utility model discloses a portable car door anti-collision bar, such as... Figure 1 and Figure 2 As shown, the device includes a telescopic guard bar 1, support pads 2, and a suspension mechanism 3. The telescopic guard bar 1 comprises multiple bar sections. Multiple support pads 2 are provided and fixedly installed on the bar sections, forming multi-point support for the telescopic guard bar 1 to enhance its stability. The suspension mechanism 3 can be fixedly connected to different support pads 2 according to different vehicle models, or fixedly connected to different positions on the telescopic guard bar 1, and can be connected to the vehicle body, thus allowing the telescopic guard bar 1 to be installed on different vehicle models. Compared with existing technologies, the suspension mechanism 3 can be fixedly connected to different support pads 2 according to different vehicle models, or fixedly connected to different positions on the telescopic guard bar 1, enabling the door impact bar to be installed on various vehicle models and effectively protect them. This expands the applicability of the door impact bar, improves its adaptability and versatility, and is easy to use and carry.

[0032] Preferably, the rod section has a mounting part located at the head end of the rod section. The mounting part is used to fix and install the support pad 2. When the telescopic protective rod 1 is retracted, the multiple support pads 2 can contact each other tightly, thereby minimizing the length of the door anti-collision rod and reducing the space required for storage. This allows it to be easily stored in the door storage compartment, making it convenient for the driver to take out and put in, without having to go to the trunk to take it out each time.

[0033] Preferably, the suspension mechanism 3 includes a first suspension mechanism and a second suspension mechanism, both of which can be connected to the door handle. The first and second suspension mechanisms can also be fixedly connected to different support pads 2 according to the distance between the door handles (i.e., the front door handle and the rear door handle) of different car models, or fixedly connected to different positions of the telescopic guard bar 1, thereby enabling the door anti-collision bar to be installed on the body of different car models, so that the door anti-collision bar can provide protection for multiple car models, which not only expands the application range of the door anti-collision bar, but also improves its adaptability and versatility.

[0034] Preferably, such as Figure 3 As shown, the first suspension mechanism and the second suspension mechanism have the same structure. The first suspension mechanism includes a hook 31 and a connector 32. The connector 32 includes a male lock buckle 321 and a female lock buckle 322. The female lock buckle 322 is fixedly installed on different support pads 2 or fixedly installed at different positions of the telescopic guard bar 1. The male lock buckle 321 is fixedly connected to the hook 31 and can be inserted into the female lock buckle 322, thereby enabling the hook 31 to be fixedly connected to the support pad 2 or the telescopic guard bar 1. When the male lock buckle 321 is inserted into different female lock buckles 322, the first suspension mechanism and the second suspension mechanism are quickly fixedly connected to different support pads 2 or quickly fixedly connected to different positions of the telescopic guard bar 1, thereby enabling the door anti-collision bar to be quickly installed on the body of different vehicle models, so that the door anti-collision bar can provide protection for multiple vehicle models, thereby expanding its application range and enhancing the adaptability and versatility of the door anti-collision bar.

[0035] Preferably, such as Figure 4 and Figure 5 As shown, the male latch 321 is provided with a latch 3211, and the latch 3211 is provided with a locking protrusion; the female latch 322 is provided with a locking cavity 3221, and the inner wall of the locking cavity 3221 is provided with a locking groove; the latch 3211 can be inserted into the locking cavity 3221, and the locking protrusion can be inserted into the locking groove; when the latch 3211 is inserted into the locking cavity 3221 and the locking protrusion is inserted into the locking groove, the male latch 321 and the female latch 322 are quickly and firmly fixedly connected; conversely, when it is necessary to disengage, simply press the latch 3211 to make the locking protrusion exit the locking groove and the latch 3211 exit the locking cavity 3221, and the male latch 321 and the female latch 322 can be easily and quickly separated. The whole process is simple to operate and very convenient to use.

[0036] Preferably, the support pad 2 is circular; the diameters of the multiple support pads 2 are equal, so that all the support pads 2 can be in close contact with the vehicle body, thereby enhancing the support stability of the telescopic guard bar 1, reducing excessive deformation of the telescopic guard bar 1 caused by nearby vehicles opening their doors, and thus improving the protective performance of the door anti-collision bar; in addition, the multiple support pads 2 can contact the vehicle body and support the telescopic guard bar 1, which can achieve force distribution and avoid only some support pads 2 bearing concentrated pressure, thereby preventing damage to the vehicle body.

[0037] Preferably, the support pad 2 is not limited to a circle, but can also be any polygon, such as a triangle, a quadrilateral, a pentagon, etc.

[0038] Preferably, the outer circumference of the support pad 2 is provided with a magnetic strip. The magnetic force of the magnetic strip can be used to firmly attach the support pad 2 to the vehicle body, preventing it from slipping under the influence of external forces (such as wind), thereby avoiding damage to the vehicle paint.

[0039] Preferably, the support pad 2 is made of an elastic material.

[0040] Preferably, the door anti-collision bar also includes an anti-theft device 4, which includes an anti-theft rope 41 and a retractable device 42. The retractable device 42 is fixedly installed in the door storage compartment. One end of the anti-theft rope 41 is fixedly connected to the telescopic protective bar 1, and the other end is connected to the retractable device 42. The retractable device 42 can retract excess anti-theft rope 41.

[0041] Preferably, such as Figure 6 As shown, the take-up device 42 includes a cable box 421, a spiral spring 422, and a winding post 423. The winding post 423 is disposed inside the cable box 421 and is rotatably connected to the cable box 421. The winding post 423 is used to wind the anti-theft rope 41. One end of the spiral spring 422 is fixedly connected to the cable box 421, and the other end is fixedly connected to the winding post 423. The spiral spring 422 can drive the winding post 423 to rotate, thereby winding the excess anti-theft rope 41 extending out of the take-up device 42 onto the winding post 423 to prevent the anti-theft rope 41 from being accidentally snagged on other objects.

[0042] Preferably, the take-up device 42 further includes an isolation disc 424, which is fixedly mounted on the winding post 423 and can rotate with the winding post 423. The isolation disc 424 is used to isolate the spiral spring 422 and the anti-theft rope 41, prevent the anti-theft rope 41 from getting tangled in the spiral spring 422, and ensure the normal operation of the take-up device 42.

[0043] Example 2

[0044] Example 2 is a second structure of connector 32 in Example 1, including a nut and a bolt. The bolt is fixedly installed on different support washers 2 or at different positions of the telescopic guardrail 1. The nut is fixedly connected to the hook 31, and the nut can be threadedly connected to the bolt, thereby enabling the hook 31 to be fixedly connected to the support washer 2 or to the telescopic guardrail 1. When the nut is threadedly connected to different bolts, the first suspension mechanism and the second suspension mechanism can be quickly fixedly connected to different support washers 2 or quickly fixedly connected to different positions of the telescopic guardrail 1, thereby enabling the door anti-collision bar to be quickly installed on the body of different vehicle models, so that the door anti-collision bar can provide protection for multiple vehicle models, thereby expanding its application range and enhancing the adaptability and versatility of the door anti-collision bar. Compared with the first structure, the second structure of connector 32 enables a tighter connection between the telescopic guardrail 1 and the hook 31, effectively preventing the telescopic guardrail 1 from detaching from the hook 31.

[0045] Example 3

[0046] Example 3 is a third structure of connector 32 in Example 1, including a first gripper, a second gripper, and a clamping spring. The first or second gripper is fixedly connected to the hook 31. The first and second grippers are hinged and arranged crosswise. One end of the clamping spring is fixedly connected to the first gripper, and the other end is fixedly connected to the second gripper, and always applies an elastic thrust to the first and second grippers to keep them engaged. When the first and second grippers are pressed, they can be engaged under the elastic thrust of the clamping spring at different angles. The first and second suspension mechanisms can be quickly and securely connected to different support pads 2 or to different positions of the telescopic guard bar 1, thereby enabling the door anti-collision bar to be quickly installed on the body of different vehicle models. This allows the door anti-collision bar to provide protection for multiple vehicle models, thus expanding its application range and enhancing its adaptability and versatility. The third structure of the connector 32 is more convenient to use than the first and second structures.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
