[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] like Figure 1 and Figure 2 As shown, a walking protection device 10 provided in one embodiment of the present invention includes a protection switch 1 and a trigger 2. The protection switch 1 is adapted to be installed on the frame 20 of the vehicle 100. One end of the trigger 2 is connected to the protection switch 1, and at least a portion of the trigger 2 extends along a first direction. When the vehicle 100 travels along a second direction and collides with an external object 200, the trigger 2 can trigger the protection switch 1 to stop the vehicle 100. The first direction intersects with the second direction.

[0037] In this embodiment, in addition to being triggered by the collision protection switch 1, the external object 200 can also trigger the protection switch 1 by the collision trigger 2. Compared with the prior art setting method that only uses the protection switch 1 for protection, the setting of this embodiment can trigger the protection switch 1 over a wider range, thereby increasing the protection range of the walking protection device 10 and improving the safety of the vehicle 100 using the walking protection device 10.

[0038] Among them, the external object 200 can be a person or a thing.

[0039] When the vehicle 100 travels in the second direction, the trigger extends along the first direction intersecting the second direction, forming a protective barrier on one side of the vehicle along the second direction. When the vehicle collides with an external object, the trigger first contacts the external object, triggering the protection switch 1, and the vehicle 100 stops, minimizing the risk of collision between the vehicle 100 and the external object.

[0040] exist Figure 1 and Figure 2 Of the directions shown, the first direction is parallel to the X-axis, and the second direction is parallel to the Y-axis. Alternatively, the first and second directions can be perpendicular to each other.

[0041] In one application scenario, the first direction can be left or right, and the second direction can be front or back.

[0042] In one embodiment, the protective switch 1 has normally open and normally closed contacts. The normally closed contact is connected to the safety circuit, and the normally open contact is connected to the control circuit. When the protective switch 1 is triggered, the normally closed contact opens and the normally open contact closes. The opening of the normally closed contact disconnects the safety circuit, de-energizing the vehicle's braking device and stopping the vehicle. The closing of the normally open contact activates the control circuit, generating a corresponding electrical signal output to the controller. The controller can then control an alarm device to issue an alarm message. The controller can be, for example, a PLC or a microcontroller, and the alarm device can be a buzzer or an indicator light.

[0043] It should be noted that the structure and usage of the protective switch 1 are existing technologies.

[0044] like Figure 2 As shown, in one embodiment, the trigger 2 includes a pull rope 21, and the protection switch 1 is disposed on one side of the frame 20 along the first direction. One end of the pull rope 21 is connected to the protection switch 1, and the other end of the pull rope 21 is connected to the other side of the frame 20 along the first direction. When the trigger 2 collides with an external object 200, the pull rope 21 contacts the external object 200, thus avoiding a rigid collision between the trigger 2 and the external object 200 and improving the protective effect of the walking protection device 10.

[0045] In addition, the pull rope 21 is connected to the other side of the frame 20 along the first direction, which can increase the coverage of the pull rope 21 and improve the protection effect of the walking protection device 10.

[0046] Furthermore, using a pull cord as the trigger can reduce costs. This design also offers advantages such as impact resistance and ease of installation and maintenance.

[0047] In one embodiment, the protective switch 1 can be a pull-cord switch. The pull-cord switch is a mechanically triggered switch that maintains 100% sensitivity even after multiple consecutive triggers in a high-temperature environment. It has a stable structure and strong anti-interference capabilities. Pull-cord switches are inexpensive, readily available, reliable in structure, and easy to install and maintain.

[0048] In one embodiment, the pull cord 21 is flexible and its material can be metal, polyester, or nylon, etc.

[0049] In one embodiment, the protective switch 1 may be installed at one end of the frame 20 (defined as the first end of the frame 20), and the end of the frame 20 connected to the pull rope 21 is the second end of the frame 20. In a first direction, the first end and the second end are opposite ends of the frame 20.

[0050] like Figure 2 As shown, in one embodiment, the walking protection device 10 further includes a support base 3 and multiple guide members 4. The support base 3 is mounted on the frame of the vehicle. Multiple guide members 4 are installed on the support base 3 to guide the pull rope 21. The guide members 4 allow for reversing the direction of the pull rope 21, positioning it appropriately within the vehicle 100. Furthermore, the multiple guide members 4 enable multiple reversals of the pull rope 21, making it easier to position it correctly. This also facilitates the placement of the protection switch 1 in a suitable location.

[0051] In this context, "multiple" refers to two or more. The meaning of the word "multiple" is the same in all embodiments and will not be repeated hereafter.

[0052] like Figure 3 As shown, in one embodiment, the support base 3 is provided with a hollow structure 31, which can reduce the weight of the support base 3.

[0053] In one embodiment, each guide 4 is detachably connected to the support base 3, so that if one guide 4 is damaged, only the damaged one needs to be replaced, thereby reducing the maintenance cost of the walking protection device 10.

[0054] In one embodiment, the guide member 4 is a pulley with grooves. The grooves of multiple pulleys form a guide space for the pull rope 21 to pass through. After assembly, the pull rope 21 can be confined within the grooves, allowing it to be held in a predetermined position.

[0055] In addition, the groove surrounds the pulley, and the groove is coaxial with the pulley.

[0056] In addition, the pulley is connected to the support base 3 and can rotate relative to the support base 3 around its own axis. This reduces the friction between the pull rope 21 and the guide 4. When the pull rope 21 collides with the external object 200, it is easier to transmit the force of the pull rope 21 to the protection switch 1, so that the protection switch 1 can be triggered smoothly.

[0057] In practical scenarios, the pull rope 21 only wraps around a portion of the pulley's circumference, which facilitates the transfer of force on the pull rope 21 from one side of the pulley to the other.

[0058] like Figure 3 As shown, in one embodiment, at least one guide retainer 5 is provided on the support base 3, and the pull rope 21 is passed through the guide retainer 5 so that the pull rope 21 keeps in contact with the guide member 4.

[0059] The guide retainer 5 is provided with a guide hole, which passes through the guide retainer 5. The pull rope 21 passes through the guide hole and then passes through the guide retainer 5, thus achieving its placement on the guide retainer 5.

[0060] The sidewall of the guide hole can contact the pull rope 21 and limit the pull rope 21 passing through it so that the part of the pull rope 21 passing through the guide retainer 5 can be held in the proper position in the radial direction of the guide hole.

[0061] In addition, the limiting function of the guide retainer 5 can also effectively prevent the pull rope 21 from coming out of the pulley groove when it is hit.

[0062] In one embodiment, the guide retainer 5 may be disposed between two adjacent pulleys and spaced apart from the pulleys.

[0063] like Figures 2 to 4As shown, in one embodiment, the pull rope 21 includes a first pull rope 211, a second pull rope 212, and a third pull rope 213. The first pull rope 211 is connected between the second pull rope 212 and the third pull rope 213. The end of the second pull rope 212 away from the first pull rope 211 is connected to the protection switch 1. The end of the third pull rope 213 away from the first pull rope 211 is connected to the frame 20 of the vehicle 100. The first pull rope 211 extends in a first direction. When the first pull rope 211 collides with an external object 200, the protection switch 1 can be triggered by the second pull rope 212.

[0064] Among them, the second pull rope 212 and the third pull rope 213 are equivalent to the lead-out part of the pull rope 21, and the first pull rope 211 is equivalent to the trigger part of the pull rope 21. The lead-out part is used to make the trigger part avoid the corresponding structure on the frame 20, so that the trigger part can be more easily collided with the external object 200 of the vehicle 100, thereby improving the protection effect of the walking protection device 10.

[0065] In addition, when the first pull rope 211 collides with the external object 200, the force it receives can be transmitted to the second pull rope 212, and then to the protection switch 1, thereby triggering the protection switch 1.

[0066] In one embodiment, the first pull rope 211, the second pull rope 212, and the third pull rope 213 are all formed by the pull rope 21 being guided and reversing by the guide member 4.

[0067] The extension direction of the first pull rope 211 intersects the extension direction of the second pull rope 212, and the extension direction of the first pull rope 211 intersects the extension direction of the third pull rope 213.

[0068] In one application scenario, the second pull rope 212 extends along the second direction, and the third pull rope 213 extends along the second direction. Of course, in other embodiments, the extension direction of the first pull rope 211 can also be parallel to the extension direction of the second pull rope 212. Similarly, the extension direction of the first pull rope 211 can also be parallel to the extension direction of the third pull rope 213.

[0069] like Figure 2 , Figure 5 as well as Figure 6As shown, in one embodiment, the pull rope 21 further includes a fourth pull rope 214 and a fifth pull rope 215. The fourth pull rope 214 is connected between the first pull rope 211 and the second pull rope 212, and the fifth pull rope 215 is connected between the first pull rope 211 and the third pull rope 213. The fourth pull rope 214 and the fifth pull rope 215 extend along a third direction, and the first direction, the second direction, and the third direction intersect each other. By setting the fourth pull rope 214 and the fifth pull rope 215, the first pull rope 211 can better avoid the corresponding structure on the frame 20.

[0070] exist Figure 2 and Figure 5 Of the directions shown, the third direction is parallel to the Z-axis.

[0071] In one embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. In a scenario where the first direction is left-right and the second direction is front-back, the third direction can be up-down.

[0072] In one embodiment, the first pull rope 211, the second pull rope 212, the third pull rope 213, the fourth pull rope 214, and the fifth pull rope 215 are all formed by the pull rope 21 being guided and reversing by the guide member 4.

[0073] like Figure 3 and Figure 5 As shown, there are four guide members 4, namely a first guide member 41, a second guide member 42, a third guide member 43, and a fourth guide member 44. The first guide member 41 and the second guide member 42 form one group (defined as the first group), and the third guide member 43 and the fourth guide member 44 form another group (defined as the second group). The first group and the second group are spaced apart along a first direction. In addition, the first guide member 41 and the second guide member 42 are spaced apart along a third direction, and the third guide member 43 and the fourth guide member 44 are spaced apart along a third direction. Furthermore, the axis of the first guide member 41 is parallel to the first direction, the axis of the second guide member 42 is parallel to the second direction, the axis of the third guide member 43 is parallel to the second direction, and the axis of the fourth guide member 44 is parallel to the first direction.

[0074] After the pull rope 21 is connected to the protective switch 1, it passes sequentially around the first guide member 41, the second guide member 42, the third guide member 43, and the fourth guide member 44. The portion of the pull rope 21 between the protective switch 1 and the first guide member 41 is the second pull rope 212; the portion between the first guide member 41 and the second guide member 42 is the fourth pull rope 214; the portion between the second guide member 42 and the third guide member 43 is the first pull rope 211; the portion between the third guide member 43 and the fourth guide member 44 is the fifth pull rope 215; and the portion between the fourth guide member 44 and the area where the pull rope 21 connects to the frame 20 is the third pull rope 213.

[0075] In addition, when the third direction is up or down, the first guide member 41 can be located above the second guide member 42, and the third guide member 43 can be located below the fourth guide member 44.

[0076] In one embodiment, a guide retainer 5 is provided between the first guide member 41 and the second guide member 42, and a guide retainer 5 is also provided between the third guide member 43 and the fourth guide member 44. In addition, the first guide member 41 and the second guide member 42 are connected to a support base 3, and the third guide member 43 and the fourth guide member 44 are connected to another support base 3.

[0077] like Figure 6 As shown, in one embodiment, the walking protection device 10 further includes a damper 6 and a damper mounting base 7. The damper mounting base 7 is installed on the frame 20 of the vehicle 100. One end of the damper 6 is connected to the damper mounting base 7, and the other end of the damper 6 is connected to the trigger 2. The damper 6 absorbs the vibration of the pull rope 21, preventing the vibration of the vehicle 100 traveling in the second direction from being transmitted to the pull rope 21 and accidentally triggering the protection switch 1.

[0078] In one embodiment, the damper 6 can be a spring, such as a helical spring. When the pull rope 21 is impacted and applies force to the protective switch 1 to trigger the protective switch 1, this force can also be transmitted to the spring to cause the spring to undergo elastic deformation.

[0079] like Figure 6 As shown, in one embodiment, the third section of the pull rope 213 is connected to a spring, in which case the spring can produce elastic deformation in the second direction.

[0080] In addition, the spring has hooks at both ends, one end of which is connected to the damper mounting base 7, and the other end of which is connected to the pull rope 21.

[0081] like Figure 6As shown, in one embodiment, the damper mounting base 7 includes a base 71 and a pull ring 72. The base 71 is connected to the frame 20, and the spring is connected to the pull ring 72. When the spring has a hook, the hook is hooked onto the pull ring 72.

[0082] like Figure 1 As shown, one embodiment of this utility model also provides a transport vehicle 100, which includes a frame 20, a walking device 30, and a walking protection device 10 described in any of the above-mentioned embodiments. The walking device 30 is installed at the bottom of the frame 20, and the protection switch 1 is installed on the frame 20. This arrangement can improve the safety of the transport vehicle 100.

[0083] Among them, the walking device 30 can be an AGV trolley, etc.

[0084] In one embodiment, in the second direction, walking protection devices 10 are provided on both opposite sides of the frame 20.

[0085] An embodiment of this utility model also provides a laminating device, which includes a running track 300 (reference). Figure 1 The frame 20 includes a laminator and the aforementioned transport vehicle 100, which moves along the running track 300 to transport materials from the frame 20 to the laminator or remove materials from the laminator.

[0086] The setting of the running track 300 can ensure the distance between the transport vehicle 100 and the laminating equipment, which is conducive to placing materials into the laminating equipment and removing materials from the laminating equipment.

[0087] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0088] In other embodiments, the portion of the pull rope 21 along the first direction can also be replaced by a swing arm, which can be a rod-shaped or plate-shaped structure.

[0089] In other embodiments, the pulley may be non-rotatable relative to the support 3. Alternatively, the pulley may be replaced by a pivot, which may be a cylindrical structure.

[0090] In other embodiments, the damper 6 may also be a hydraulic or pneumatic damping device.

[0091] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
