However, if the driver delays or makes a mistake in operation, it is still easy for the forklift to collide with the obstacle, which may cause a dangerous accident in serious cases. Utility Model Content

[0003] The utility model provides a forklift reversing anti-collision system and a forklift, which are used to solve the problem that the existing forklift is prone to reversing collision and thus causes dangerous accidents.

[0004] According to a first aspect of the utility model, a forklift back-up collision avoidance system is provided, comprising:

[0005] A distance detection device, the distance detection device is used to detect the distance between the rear of the forklift and the obstacle;

[0006] An auxiliary brake drive device, the auxiliary brake drive device is connected to the brake pedal of the forklift and is used to assist in adjusting the braking state of the brake pedal;

[0007] A control device is connected to the distance detection device and the auxiliary brake drive device, and is used to adjust the working state of the auxiliary brake drive device based on the detection result of the distance detection device.

[0008] According to a forklift reverse collision avoidance system provided by the utility model, the auxiliary brake drive device includes a braking position and a release position. In the braking position, the auxiliary brake drive device can press the brake pedal. In the release position, the auxiliary brake drive device can release the brake pedal.

[0009] According to a reversing anti-collision system for a forklift provided by the utility model, when the actual distance between the rear of the forklift and the obstacle is greater than a first preset distance value, and the actual distance is less than or equal to a second preset distance value, the control device controls the auxiliary brake drive device to first switch to the braking position and then switch to the release position.

[0010] Wherein, the first preset distance value is smaller than the second preset distance value.

[0011] According to a forklift reversing collision avoidance system provided by the utility model, when the actual distance between the rear of the forklift and the obstacle is less than or equal to a first preset distance value, the control device controls the auxiliary brake drive device to switch and maintain it in the braking position.

[0012] According to a forklift reversing anti-collision system provided by the utility model, the auxiliary brake drive device includes a drive member and a telescopic pull rod.

[0013] The driving member is connected to the telescopic rod, and the telescopic rod is used to be connected to the brake pedal. The driving member is used to drive the telescopic rod to switch between the braking position and the releasing position.

[0014] According to the forklift reverse collision avoidance system provided by the utility model, in the braking position, the driving member can drive the telescopic rod to retract to switch the brake pedal to the braking state. In the release position, the driving member can release the telescopic rod so that the telescopic rod can freely retract and retract along with the brake pedal.

[0015] According to the utility model, a forklift reversing collision avoidance system is provided, the forklift reversing collision avoidance system further comprises a display screen which is connected to the distance detection device and the auxiliary brake drive device and is used to display the detection result of the distance detection device and the working state of the auxiliary brake drive device.

[0016] According to a forklift reversing anti-collision system provided by the utility model, the distance detection device includes a radar detector.

[0017] According to the forklift reversing anti-collision system provided by the utility model, the distance detection device is installed in the forklift taillight lampshade.

[0018] According to a second aspect of the utility model, a forklift is provided, comprising the forklift reverse collision avoidance system as described above.

[0019] The reverse collision avoidance system for a forklift provided by the utility model includes a distance detection device, an auxiliary brake drive device and a control device. Among them, the distance detection device is installed at the rear of the forklift and is used to detect the distance between the rear of the forklift and the obstacle. The auxiliary brake drive device is connected to the brake pedal of the forklift. The auxiliary brake drive device can assist in adjusting the braking state of the brake pedal. For example, the auxiliary brake drive device can press or release the brake pedal. When it presses the brake pedal, the forklift can be put into a braking state; when it releases the brake pedal and no other external force acts on the brake pedal, the forklift can be put into a brake-released state. The control device is connected to the distance detection device and the auxiliary brake drive device, and the distance detection device can send the detection result to the control device. The control device can adjust the working state of the auxiliary brake drive device based on the detection result of the distance detection device to make it press / drag or release the brake pedal.

[0020] During the forklift's reversing process, when the distance detection device detects that the distance between the forklift's rear end and the obstacle is relatively close, the control device automatically adjusts the working state of the auxiliary brake drive device to switch the dynamic brake pedal to the braking state, thereby assisting the forklift in braking. When the distance detection device does not detect an obstacle, or detects that the distance between the forklift's rear end and the obstacle is relatively far, the control device can adjust the working state of the auxiliary brake drive device to restore the brake pedal to a normal state. That is, in a normal state, when the driver steps on the brake pedal, the forklift brakes, and when the driver does not step on the brake pedal, the forklift releases the brakes.

[0021] With this structural arrangement, during the forklift's reversing process, the control device can automatically adjust the working state of the auxiliary brake drive device based on the detection result of the distance detection device, so as to automatically assist the brake pedal to perform the forklift braking operation when the rear of the forklift approaches an obstacle. Thus, it is possible to avoid the occurrence of dangerous accidents such as collisions caused by delayed operation or misoperation by the driver.

[0022] Furthermore, in the forklift provided by the present invention, since both are equipped with the forklift reversing anti-collision system as described above, they also have the advantages as described above. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0032] Combine the following Figure 1 A forklift reversing anti-collision system and a forklift provided by the utility model are described. It should be understood that the following description is only an illustrative embodiment of the utility model and does not constitute any particular limitation to the utility model.

[0033] The first embodiment of the utility model provides a forklift reverse collision avoidance system, such as Figure 1 As shown, the forklift reversing anti-collision system includes:

[0034] A distance detection device 100, the distance detection device 100 is used to detect the distance between the rear of the forklift and the obstacle;

[0035] An auxiliary brake driving device 200, the auxiliary brake driving device 200 is connected to the brake pedal 400 of the forklift and is used to assist in adjusting the braking state of the brake pedal 400;

[0036] The control device 300 is connected to the distance detection device 100 and the auxiliary brake drive device 200 , and is used to adjust the working state of the auxiliary brake drive device 200 based on the detection result of the distance detection device 100 .

[0037] The reverse collision avoidance system for a forklift provided by the utility model includes a distance detection device 100, an auxiliary brake drive device 200 and a control device 300. The distance detection device 100 is installed at the rear of the forklift and is used to detect the distance between the rear of the forklift and an obstacle. The auxiliary brake drive device 200 is connected to the brake pedal 400 of the forklift. The auxiliary brake drive device 200 can assist in adjusting the braking state of the brake pedal 400. For example, the auxiliary brake drive device 200 can press or release the brake pedal 400. When it presses the brake pedal 400, the forklift can be put into a braking state; when it releases the brake pedal 400 and no other external force acts on the brake pedal 400, the forklift can be put into a brake-released state. The control device 300 is connected to the distance detection device 100 and the auxiliary brake drive device 200. The distance detection device 100 can send the detection result to the control device 300. The control device 300 can adjust the working state of the auxiliary brake drive device 200 based on the detection result of the distance detection device 100 to press / drag or release the brake pedal 400.

[0038] During the forklift's reversing process, when the distance detection device 100 detects that the distance between the rear of the forklift and the obstacle is relatively close, the control device 300 automatically adjusts the working state of the auxiliary brake drive device 200 to switch the dynamic brake pedal 400 to the braking state, thereby assisting the forklift in braking. When the distance detection device 100 does not detect an obstacle, or detects that the distance between the rear of the forklift and the obstacle is relatively far, the control device 300 can adjust the working state of the auxiliary brake drive device 200 to restore the brake pedal 400 to a normal state. That is, in a normal state, when the driver steps on the brake pedal 400, the forklift brakes, and when the driver does not step on the brake pedal 400, the forklift releases the brakes.

[0039] With this structural setting, during the forklift reversing process, the control device 300 can automatically adjust the working state of the auxiliary brake drive device 200 based on the detection result of the distance detection device 100, so as to automatically assist the brake pedal 400 to perform the forklift braking operation when the rear of the forklift approaches an obstacle. In this way, the occurrence of dangerous accidents such as collisions caused by delayed operation or erroneous operation by the driver can be avoided.

[0040] In one embodiment of the present invention, the auxiliary brake drive device 200 includes a braking position and a release position. In the braking position, the auxiliary brake drive device 200 can press the brake pedal 400; in the release position, the auxiliary brake drive device 200 can release the brake pedal 400.

[0041] In other words, in the state of the braking position, the auxiliary brake drive device 200 can make the brake pedal 400 in a pressed state, i.e., a braking state. In the state of the release position, the auxiliary brake drive device 200 can release the brake pedal 400, and in this state, the auxiliary brake drive device 200 does not affect the driver's normal stepping on the brake pedal 400.

[0042] In one embodiment of the present invention, when the actual distance between the rear of the forklift and the obstacle is greater than the first preset distance value and the actual distance is less than or equal to the second preset distance value, the control device 300 controls the auxiliary brake drive device 200 to first switch to the braking position and then switch to the release position.

[0043] The first preset distance value is smaller than the second preset distance value.

[0044] Further, in an embodiment of the present invention, when the actual distance between the rear of the forklift and the obstacle is less than or equal to the first preset distance value, the control device 300 controls the auxiliary brake drive device 200 to switch and maintain the braking position.

[0045] For example, the first preset distance value is 0.5 meters, and the second preset distance value is 1 meter. When the distance detection device 100 detects that the actual distance between the rear of the forklift and the obstacle is greater than 0.5 meters and less than or equal to 1 meter, the control device 300 controls the auxiliary brake drive device 200 to switch to the braking position first, and then switch to the release position. In other words, the control device 300 controls the auxiliary brake drive device 200 to drive the brake pedal 400 to brake once. On the one hand, it can assist braking; on the other hand, it can prompt the driver. When the distance detection device 100 detects that the actual distance between the rear of the forklift and the obstacle is less than or equal to 0.5 meters, the control device 300 controls the auxiliary brake drive device 200 to switch and remain in the braking position. In other words, the control device 300 controls the auxiliary brake drive device 200 to drive the pedal 400 to perform continuous braking, or locking. In this way, the forklift can be prevented from colliding with the obstacle.

[0046] It should be understood that the auxiliary brake drive device 200 is also equipped with a button for switching the working state, which can be installed in the cab. When the auxiliary brake drive device 200 is switched and maintained in the braking position, if the driver still wants to continue to reverse and approach the obstacle, he can manually press the button to switch its working position to the release position.

[0047] It should be noted that the above embodiment is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention. In other words, the first preset distance value and the second preset distance value can be set according to actual needs.

[0048] In one embodiment of the present invention, the auxiliary brake driving device 200 includes a driving member and a telescopic pull rod.

[0049] The driving member is connected to the telescopic rod, the telescopic rod is used to be connected to the brake pedal 400, and the driving member is used to drive the telescopic rod to switch between the braking position and the release position.

[0050] Furthermore, in one embodiment of the utility model, in the braking position, the driving member can drive the telescopic rod to retract to switch the brake pedal 400 to the braking state; in the release position, the driving member can release the telescopic rod so that the telescopic rod can freely retract and retract with the brake pedal 400.

[0051] For example, the driving member is a cylinder. The piston rod of the cylinder is connected to one end of the telescopic rod, and the other end of the telescopic rod is connected to the brake pedal 400. The piston rod of the cylinder can shrink or float. For example, when the rod chamber of the cylinder is inflated, the piston rod of the cylinder can shrink. At this time, the piston rod of the cylinder can drive the telescopic rod to pull the brake pedal 400, so that the brake pedal 400 is switched to a pressed brake state. When the rod chamber and the rodless chamber of the cylinder are both connected to the atmosphere, the piston rod of the cylinder is in a floating state, and then the telescopic rod is also in a free state, which can freely expand and contract with the brake pedal 400. In this state, the telescopic rod does not affect the driver's normal action of stepping on and releasing the brake pedal 400.

[0052] In one embodiment of the utility model, the reverse collision avoidance system for a forklift further includes a display screen 500. The display screen 500 is connected to the distance detection device 100 and the auxiliary brake drive device 200, and is used to display the detection result of the distance detection device 100 and the working state of the auxiliary brake drive device 200. Thus, the driver can understand the distance between the rear of the forklift and the obstacle in real time, and determine the working state of the auxiliary brake drive device 200 in real time.

[0053] In one embodiment of the present invention, the distance detection device 100 includes a radar detector.

[0054] In another embodiment of the present invention, the distance detection device 100 is installed in the taillight cover of a forklift, thereby saving space and realizing the above functions without any damage to the forklift.

[0055] An embodiment of a second aspect of the utility model provides a forklift, comprising the forklift reversing anti-collision system as described above.

[0056] Furthermore, in the forklift provided by the present invention, since it includes the forklift reversing anti-collision system as described above, it also has the advantages as described above.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
