Abstract
Description
Technical Field
[0001] The utility model relates to the field of mobile equipment protection, in particular to an anti-collision detection device. Background Art
[0002] The batteries of new energy vehicles require cooling during operation to ensure stable and safe performance, while the air conditioning system also requires refrigerant to function properly. On the automotive production line, refilling refrigerant or coolant into the vehicles being assembled is a critical step in ensuring the vehicle's subsequent performance.
[0003] However, vehicles are constantly moving on the production line, progressing through each production stage. To accurately refill refrigerant or coolant onto these moving vehicles, the corresponding refueling equipment must also move with them. While this mobile refueling model improves production efficiency, it also carries certain risks. Due to limited space on the production line and the simultaneous operation of multiple machines, refueling equipment can easily collide with other equipment or obstacles while following the vehicle. This can damage the refueling equipment and disrupt the normal operation of the entire production line. Therefore, to ensure smooth production, mobile equipment like refueling equipment on the automotive production line is equipped with anti-collision devices. This anti-collision device can detect when the mobile equipment comes into contact with other objects and take appropriate measures to prevent collisions, thereby ensuring the safety of the mobile equipment and the continued stable operation of the production line. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problem that mobile equipment, while following a vehicle, is prone to collisions with other equipment or obstacles, resulting in damage to the mobile equipment. This utility model provides an anti-collision detection device that can promptly sense when a mobile equipment contacts another object and take appropriate measures to avoid the collision, thereby ensuring the safety of the mobile equipment and the continued stable operation of the production line.
[0005] In order to solve the above technical problems, the embodiment of the present utility model discloses an anti-collision detection device, which includes:
[0006] a bracket extending in a first direction, the bracket being configured to connect to an external mobile device, the external driving member being configured to drive the external mobile device to move in a second direction, the second direction being perpendicular to the first direction;
[0007] a slide rail extending along the second direction and connected to the bracket in a manner of being slidable along the second direction;
[0008] an anti-collision portion, connected to a front end of the slide rail along the second direction, and configured to contact an external moving object;
[0009] A travel switch, the travel switch being connected to the bracket and being used for electrically connecting to an external driving member;
[0010] a detection portion, along a third direction, the detection portion being connected to one side of the slide rail, the detection portion extending along the second direction, the third direction being perpendicular to the first direction;
[0011] an elastic member, wherein along the third direction, the elastic member is located on the other side of the slide rail; along the second direction, one end of the elastic member is connected to the bracket, and the other end of the elastic member is connected to the rear end of the slide rail;
[0012] The anti-collision detection device includes a collision state and a non-collision state;
[0013] In the non-collision state, along the first direction, the travel switch and the detection portion are spaced apart, and the elastic member is in a compressed state;
[0014] In the collision state, the travel switch contacts the detection portion, and the elastic member is in an extended state.
[0015] With this solution, the anti-collision component is connected to the front end of the slide rail, placing it at the very front end of the anti-collision detection device in its moving direction. This ensures that when a moving object crosses the device's path, the anti-collision component is the first structure to come into contact with it.
[0016] When the anti-collision component contacts a moving object, the anti-collision detection device continues to move in the predetermined second direction. This relative motion causes the anti-collision component to experience an impact force from the moving object. This impact force causes the anti-collision component to move in a direction opposite to the direction of movement of the bracket. Because the anti-collision component is connected to the slide rail, this movement causes the slide rail to slide along with it. The sliding motion of the slide rail is then transmitted to the detection component, causing it to also slide in a direction opposite to the direction of movement of the bracket.
[0017] In this series of chain reactions, the detection part will change from being spaced apart from the limit switch to being in contact with the limit switch, that is, the anti-collision detection device will switch from a non-collision state to a collision state. When the moving object has not moved away, the detection part will continue to be in contact with the limit switch. This contact is not short-term and discrete, but forms a continuous contact signal. Once the limit switch receives this continuous contact signal, it will send an electrical signal to stop moving to the external drive component. After receiving this electrical signal, the external drive component will immediately stop working, causing the external mobile device to stop moving. At the same time, the anti-collision detection device connected to the external mobile device will also stop moving, effectively avoiding equipment damage and production accidents that may be caused by collisions.
[0018] Furthermore, when the anti-collision component contacts an external moving object and in the subsequent chain reaction, the elastic member, originally in a compressed state, gradually transitions from a compressed state to an extended state under the action of these forces. When the external moving object moves away, the stored elastic potential energy of the elastic member is converted into kinetic energy, generating a rebound force. This rebound force acts on the slide rail, driving it to slide in the second direction. As the slide rail slides, the detection component also slides in the same direction as the bracket's movement, gradually transitioning from contact with the limit switch to a position spaced apart from it. This transitions the anti-collision detection device from a collision state to a non-collision state. In this state, the limit switch no longer receives a continuous contact signal and transmits an electrical signal to the external driver to initiate movement. Upon receiving this electrical signal, the external driver resumes operation, driving the external mobile device to move again in the second direction. Simultaneously, the anti-collision detection device, connected to the external mobile device, also resumes movement, allowing the entire production process to continue smoothly.
[0019] Therefore, the anti-collision detection device in the present application can timely sense and take corresponding measures when the mobile device contacts other objects to avoid collision, thereby ensuring the safety of the mobile device and the continuous and stable operation of the production line.
[0020] When the external drive element is just activated and in its initial operation, the external mobile device, driven by the external drive element, begins to move the anti-collision detection device in the second direction. However, due to inertia, the slide rail remains in its original position. At this point, if observed with the moving bracket as a reference, it can be seen that the slide rail is sliding in the direction opposite to the bracket's movement.
[0021] The occurrence of this relative movement affects the elastic member connecting the bracket and the slide rail. In this case, the elastic member, originally in a compressed state, will briefly change its state from a compressed state to an elongated state due to the slide rail sliding in the opposite direction relative to the bracket. As the state of the elastic member changes, the elastic potential energy stored within it begins to take effect, generating an elastic force acting on the slide rail. The slide rail is subjected to tension, and its sliding direction begins to change. The slide rail, which originally slid in the direction opposite to the movement of the bracket, gradually changes its direction of movement, eventually shifting to the same direction as the bracket's movement. During this process, the elastic member continues to adjust with the movement of the slide rail until it returns to a compressed state.
[0022] The duration of the above process is relatively short, and within this brief period, two different situations may occur. In one case, the detection unit remains spaced from the limit switch, with no contact between the two. In the other case, although the detection unit and the limit switch may make contact, this contact is brief and discontinuous. Because the limit switch requires a continuous and stable contact signal to respond, in this case of brief contact or no contact, the limit switch will not produce any action, and the entire anti-collision detection equipment will continue to operate as planned.
[0023] In addition, in the present application, when the anti-collision detection device is in a non-collision state, the elastic member is in a compressed state, and when the anti-collision detection device is in a collision state, the elastic member is in an extended state, which greatly increases the buffering stroke of the anti-collision detection device.
[0024] According to another specific embodiment of the present invention, the detection portion includes a first portion, an oblique portion, and a second portion connected in sequence, wherein the height of the first portion is greater than the height of the second portion, and along the second direction, the first portion is located between the anti-collision portion and the oblique portion;
[0025] In the non-collision state, along the first direction, the travel switch is spaced apart from the second portion;
[0026] In the collision state, the first portion contacts the travel switch.
[0027] With this technical solution, when the anti-collision portion contacts a moving object, the anti-collision detection device gradually transitions from a non-collision state to a collision state. Thanks to the inclined section, the travel switch gradually contacts the first portion during this transition, rather than suddenly colliding with it. This gradual contact effectively avoids damage to the travel switch caused by sudden, intense impacts, ensuring its proper operation.
[0028] Furthermore, at the moment the external drive is activated, the bracket, carrying the limit switch, begins moving in the second direction, while the slide rail remains in its original position due to inertia. At this point, the limit switch transitions from being spaced apart from the second portion to being spaced apart from the inclined portion. Therefore, the inclined portion acts as a buffer zone, preventing the limit switch from directly contacting the first portion at the moment the drive is activated. Without the inclined portion as a buffer zone, the limit switch would directly contact the first portion, causing the system to misjudge a collision, thereby affecting the normal operation of the entire device.
[0029] According to another specific embodiment of the present invention, the bracket includes a vertical structure and a horizontal structure, the vertical structure extends along the first direction, the vertical structure is used to connect with an external mobile device, and the horizontal structure extends along the third direction. The bracket also includes a plurality of sliders arranged on the horizontal structure, the plurality of sliders are arranged at intervals along the second direction, and the plurality of sliders are slidably connected to the slide rail.
[0030] By adopting the above technical solution, a plurality of sliders are slidably connected to the slide rail, thereby enabling the detection portion to slide relative to the horizontal structure along the second direction, thereby enabling the travel switch to contact the first portion.
[0031] In the present application, the slider is typically a block-shaped structure, and its contact with the slide rail is surface contact. When the entire device is subjected to torque, the torque will generate a distributed force on the contact surface between the slider and the slide rail. Taking the case of a square slider and a rectangular slide rail as an example, when torque is applied to the anti-collision detection device, the torque will cause the sides of the slider to squeeze or rub against the corresponding sides of the slide rail. Since the contact area of this surface contact method is relatively large, the force generated by the torque can be dispersed over this larger contact surface, allowing the entire structure to withstand greater torque without damage. Moreover, the multiple sliders and the slide rail are a synchronized whole. Even if a moving object hits one end of the anti-collision part, the slide rail will slide relative to the multiple sliders, and the slide rail and the sleeve will not be misaligned. Therefore, the connection method of multiple sliders and the slide rail can improve the torsional strength of the anti-collision detection device, so that it can still maintain a stable and reliable operating state when facing complex external forces.
[0032] According to another specific embodiment of the present invention, along the third direction, both sides of the vertical structure include a plurality of mounting members spaced apart along the first direction, and the mounting members are used to connect to external mobile devices.
[0033] According to another specific embodiment of the present utility model, the travel switch includes a travel switch body and a connecting member, the connecting member includes a vertical portion and a horizontal portion, the vertical portion extends along the first direction, the horizontal portion extends along the third direction, the travel switch body is connected to the vertical portion, and the horizontal portion is connected to the horizontal structure;
[0034] In the non-collision state, along the first direction, the travel switch body and the second portion of the detection portion are spaced apart;
[0035] In the collision state, the first portion of the detection portion contacts the travel switch body.
[0036] According to another specific embodiment of the present invention, the vertical portion is connected to the travel switch body via bolts, and the vertical portion includes a plurality of long holes, and the length of the long holes is greater than the diameter of the bolts.
[0037] With the above-mentioned technical solution, achieving absolutely precise dimensions during the connector production process is difficult, and a certain degree of production error will occur. To address this, the length of the slotted hole in the connector is intentionally set to be greater than the bolt diameter. Even if the slotted hole is not precisely positioned, but the length is greater than the bolt diameter, the travel switch body can still be accurately fixed in the desired position, thus leaving room for error in the connector production process.
[0038] According to another specific embodiment of the present utility model, the anti-collision detection device includes a first limiter, which is provided at the rear end of the slide rail along the second direction, and is provided above the slide rail along the first direction. The bracket includes a limiter structure, which extends along the third direction, and both ends of the limiter structure are respectively connected to the vertical structure;
[0039] In the non-collision state, along the second direction, the first limiting member contacts the limiting structure;
[0040] In the collision state, the first limiting member is not in contact with the limiting structure.
[0041] With this technical solution, when the moving object moves away, the anti-collision detection device transitions from a collision state to a non-collision state. The resilient force of the elastic member acts on the slide rail, causing it to slide back to its original position in the second direction. When the first limit member contacts the limit structure, the slide rail's movement is restricted, and the slide rail can no longer slide in the current direction, indicating that the slide rail has returned to its original position. This separation between the travel switch body and the second portion prevents the slide rail from separating from the slider.
[0042] According to another specific embodiment of the present invention, the anti-collision detection device includes a second limiting member, and along the second direction, the second limiting member is arranged at the front end of the slide rail, along the first direction, the second limiting member is arranged above the slide rail, and in the non-collision state, along the second direction, the second limiting member is spaced apart from the limiting structure.
[0043] With this technical solution, when a moving object collides with the anti-collision portion, the slide rail, under the force of the impact, begins to drive the second stopper to slide relative to the slider in the second direction. During this process, the second stopper gradually approaches the stopper structure as the slide rail moves. When the second stopper contacts the stopper structure, the slide rail's movement is restricted, and the slide rail can no longer slide in the current direction, preventing it from separating from the slider.
[0044] According to another specific embodiment of the present invention, the anti-collision detection device includes a buffer component, which is arranged at the rear end of the slide rail along the second direction, and is spaced apart from the first limiting component along the third direction. In the non-collision state, the buffer component is in contact with the limiting structure along the second direction.
[0045] With the above technical solution, when the moving object moves away, the anti-collision detection device transitions from a collision state to a non-collision state. The rebound force of the elastic member acts on the slide rail, causing it to slide back to its original position along the second direction. The rebound force generated by the elastic member is often relatively large. Without a buffer member to dissipate some of the rebound force, the first limit member moves rapidly along the slide rail. Under such high-speed movement, the first limit member is likely to instantly collide with the limit structure. At this time, the impact force can easily cause serious damage to the limit structure, thereby affecting the normal function and service life of the entire anti-collision detection device.
[0046] According to another specific embodiment of the present invention, the anti-collision portion is made of flexible rubber material.
[0047] By adopting the above technical solution, the rubber material can flexibly contact the person being hit or the moving object to prevent the person being hit from being injured. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0069] refer to Figures 1 to 3 An embodiment of the present application provides an anti-collision detection device, which includes a bracket 10, a slide rail 20, an anti-collision portion 30, a travel switch 40, a detection portion 50 and an elastic member 60.
[0070] The bracket 10 extends along a first direction X and is configured to connect to an external mobile device (not shown). The external driver (not shown) is configured to drive the external mobile device in a second direction Y, which is perpendicular to the first direction X. The external driver may be a motor or a cylinder, and the external mobile device may be a filling machine, material handling equipment, or an automated guided vehicle. The slide rail 20 extends along the second direction Y and is slidably connected to the bracket 10 in the second direction Y.
[0071] Along the second direction Y, the anti-collision portion 30 is connected to the front end of the slide rail 20, and the anti-collision portion 30 is used to contact an external moving object (not shown in the figure), such as a machine, a field worker, etc. The limit switch 40 is connected to the bracket 10, and the limit switch 40 is used to be electrically connected to an external driving member. Along the third direction Z, the detection portion 50 is connected to one side of the slide rail 20, and the detection portion 50 extends along the second direction Y, and the third direction Z is perpendicular to the first direction X. Along the third direction Z, the elastic member 60 is located on the other side of the slide rail 20, and along the second direction Y, one end of the elastic member 60 is connected to the bracket 10, and the other end of the elastic member 60 is connected to the rear end of the slide rail 20.
[0072] The anti-collision detection device has a collision state and a non-collision state. In the non-collision state, the travel switch 40 and the detection unit 50 are spaced apart along the first direction X, and the elastic member 60 is in a compressed state. In the collision state, the travel switch 40 is in contact with the detection unit 50, and the elastic member 60 is in an extended state.
[0073] With this solution, the anti-collision member 30 is connected to the front end of the slide rail 20, placing it at the very front end of the anti-collision detection device in its moving direction. This ensures that when a moving object crosses the device's path, the anti-collision member 30 is the first structure to come into contact with it.
[0074] When the anti-collision portion 30 contacts a moving object, at that moment, the anti-collision detection device continues to move along the predetermined second direction Y. Due to this relative motion, the anti-collision portion 30 is subjected to an impact force from the moving object. Under the action of this impact force, the anti-collision portion 30 moves in a direction opposite to the direction of movement of the bracket 10. Since the anti-collision portion 30 is connected to the slide rail 20, this movement will cause the slide rail 20 to slide together. The sliding of the slide rail 20 is further transmitted to the detection portion 50, causing the detection portion 50 to also slide in a direction opposite to the direction of movement of the bracket 10.
[0075] In this series of chain reactions, the detection part 50 will change from being spaced apart from the limit switch 40 to being in contact with the limit switch 40, that is, the anti-collision detection device switches from a non-collision state to a collision state. When the moving object has not moved away, the detection part 50 will always be in contact with the limit switch 40. This contact is not short-term and discrete, but forms a continuous contact signal. Once the limit switch 40 receives this continuous contact signal, it will send an electrical signal to stop moving to the external drive component. After receiving this electrical signal, the external drive component will immediately stop working, thereby causing the external mobile device to stop moving. At the same time, the anti-collision detection device connected to the external mobile device will also stop moving, thereby effectively avoiding equipment damage and production accidents that may be caused by collisions.
[0076] Furthermore, when the anti-collision portion 30 contacts an external moving object and in the subsequent chain reaction, the elastic member 60, originally in a compressed state, gradually transitions from a compressed state to an extended state under the action of these forces. When the external moving object moves away, the stored elastic potential energy of the elastic member 60 is converted into kinetic energy, generating a rebound force. This rebound force acts on the slide rail 20, driving the slide rail 20 to slide in the second direction Y. As the slide rail 20 slides, the detection portion 50 also slides in the same direction as the movement of the bracket 10, gradually transitioning from contact with the limit switch 40 to a position spaced apart from the limit switch 40. This means that the anti-collision detection device switches from a collision state to a non-collision state. In this state, the limit switch 40 no longer receives a continuous contact signal and transmits an electrical signal to the external driver to initiate movement. Upon receiving this electrical signal, the external driver resumes operation, driving the external mobile device to move again in the second direction Y. Simultaneously, the anti-collision detection device connected to the external mobile device also resumes movement, allowing the entire production process to continue smoothly.
[0077] Therefore, the anti-collision detection device in the present application can timely sense and take corresponding measures when the mobile device contacts other objects to avoid collision, thereby ensuring the safety of the mobile device and the continuous and stable operation of the production line.
[0078] When the external drive element is just activated and in its initial operation, the external mobile device, driven by the external drive element, drives the anti-collision detection device to begin moving in the second direction Y. However, due to inertia, the slide rail 20 remains in its original position. At this point, if the moving bracket 10 is used as a reference system, it can be seen that the slide rail 20 is sliding in a direction opposite to the direction of movement of the bracket 10.
[0079] The occurrence of this relative movement will have an impact on the elastic member 60 connecting the bracket 10 and the slide rail 20. In this case, the elastic member 60, which was originally in a compressed state, will briefly change its state from a compressed state to an elongated state due to the reverse sliding of the slide rail 20 relative to the bracket 10. As the state of the elastic member 60 changes, the elastic potential energy stored inside it begins to play a role, generating an elastic force acting on the slide rail 20. The slide rail 20 is subjected to tension, and its sliding direction begins to change. The slide rail 20, which originally slid in the direction opposite to the movement direction of the bracket 10, gradually changed its movement direction and eventually turned into the same direction as the movement direction of the bracket 10. In this process, the elastic member 60 is also constantly adjusting with the movement of the slide rail 20 until it returns to a compressed state.
[0080] The time taken for the above process to occur is relatively short. During this short period of time, two different situations may occur. In one case, the detection part 50 still maintains a state of being spaced apart from the limit switch 40, and there is no contact between the two. In the other case, although the detection part 50 and the limit switch 40 may come into contact, this contact is short-lived and discontinuous. Since the working principle of the limit switch 40 is that it needs to receive a continuous and stable contact signal before it will respond, in the case of such short contact or no contact, the limit switch 40 will not produce any action, and the entire anti-collision detection equipment will continue to operate as planned.
[0081] In addition, in the present application, when the anti-collision detection device is in a non-collision state, the elastic member 60 is in a compressed state, and when the anti-collision detection device is in a collision state, the elastic member 60 is in an extended state, which greatly increases the buffering stroke of the anti-collision detection device.
[0082] It should be noted that the specific structure of the elastic member 60 is not specifically limited in this embodiment of the present application. For example, in other possible embodiments, the elastic member 60 may be a spring, an elastic alloy, etc. The length of the slide rail 20 is not specifically limited in this embodiment of the present application. For example, in other possible embodiments, the length of the slide rail 20 may be 100 cm, 115 cm, 123 cm, etc. The length of the slide rail 20 is determined by the specific situation.
[0083] In some possible implementations, reference Figures 3 to 4B The detection portion 50 includes a first portion 51, an oblique portion 52, and a second portion 53 connected in sequence. The first portion 51 is taller than the second portion 53. Along the second direction Y, the first portion 51 is located between the anti-collision portion 30 and the oblique portion 52. In the non-collision state, along the first direction X, the limit switch 40 is spaced apart from the second portion 53. In the collision state, the first portion 51 contacts the limit switch 40.
[0084] With this technical solution, when the anti-collision portion 30 contacts a moving object, the anti-collision detection device gradually transitions from a non-collision state to a collision state. Due to the provision of the inclined section 52, the travel switch 40 can gradually and gently contact the first portion 51 during this gradual transition, rather than suddenly colliding with the first portion 51. This gradual contact effectively avoids damage to the travel switch 40 caused by a sudden, strong impact, ensuring the normal operation of the travel switch 40.
[0085] In addition, at the moment the external driving member is activated, the bracket 10 starts to move along the second direction Y with the limit switch 40, while the slide rail 20 remains in its original position due to the influence of inertia. At this time, the limit switch 40 changes from a state of being spaced apart from the second part 53 to a state of being spaced apart from the oblique section 52. Therefore, the oblique section 52 can serve as a buffer zone to prevent the limit switch 40 from directly contacting the first part 51 at the moment the driving member is activated. If there is no oblique section 52 as a buffer zone, the limit switch 40 will directly contact the first part 51, causing the system to misjudge and mistakenly believe that a collision has occurred, thereby affecting the normal operation of the entire device.
[0086] In some possible implementations, reference Figures 1 to 3 The bracket 10 includes two vertical structures 11 and a horizontal structure 12. The vertical structure 11 is a rectangular parallelepiped and extends along a first direction X. The vertical structure 11 is used to connect to an external mobile device. The horizontal structure 12 extends along a third direction Z. The bracket 10 also includes two sliders 13 disposed on the horizontal structure 12. The two sliders 13 are spaced apart along a second direction Y and are slidably connected to the slide rail 20.
[0087] By adopting the above technical solution, the two sliders 13 are slidably connected to the slide rail 20 , so that the detection part 50 can slide relative to the horizontal structure 12 along the second direction Y, thereby enabling the travel switch 40 to contact the first part 51 .
[0088] In the present application, the slider 13 is typically a block-shaped structure, and its contact with the slide rail 20 is surface contact. When the entire device is subjected to torque, the torque generates a distributed force on the contact surface between the slider 13 and the slide rail 20. Taking the case of a square slider 13 and a rectangular slide rail 20 as an example, when torque is applied to the anti-collision detection device, the torque causes the various sides of the slider 13 to squeeze or rub against the corresponding sides of the slide rail 20. Because the contact area of this surface contact method is relatively large, the force generated by the torque can be dispersed across this larger contact surface, allowing the entire structure to withstand greater torque without damage. Moreover, the multiple sliders 13 and the slide rail 20 are synchronized as a whole. Even if a moving object hits one end of the anti-collision portion 30, the slide rail 20 will slide relative to the multiple sliders 13, and the slide rail 20 will not be misaligned with the sleeve. Therefore, the connection method of multiple sliders 13 and the slide rail 20 can improve the torsional strength of the anti-collision detection device, allowing it to maintain a stable and reliable operation even in the face of complex external forces.
[0089] It should be noted that the embodiment of the present application does not impose any specific limitation on the number of vertical structures 11. For example, in other possible implementations, the number of vertical structures 11 can be three, four, etc. The embodiment of the present application does not impose any specific limitation on the number of sliders 13. For example, in other possible implementations, the number of sliders 13 can be three, four, etc. The embodiment of the present application does not impose any specific limitation on the shape of the vertical structure 11. For example, in other possible implementations, the shape of the vertical structure 11 can be a cylinder, an irregular body, etc. The embodiment of the present application does not impose any specific limitation on the length of the vertical structure 11. For example, in other possible implementations, the length of the vertical structure 11 can be 113 cm, 135 cm, 146 cm, etc. The length of the vertical structure 11 depends on the specific situation.
[0090] In some possible implementations, reference Figures 1 to 3 Along the third direction Z, both sides of the vertical structure 11 include two mounting members 111 spaced apart along the first direction X, and the mounting members 111 are used to connect to external mobile devices.
[0091] It should be noted that the embodiment of the present application does not impose any specific limitation on the number of mounting members 111 included on each side of the vertical structure 11. For example, in other possible implementations, the number of mounting members 111 included on each side of the vertical structure 11 may be one, three, and so on.
[0092] In some possible implementations, reference Figures 1 to 3 The limit switch 40 includes a limit switch body 41 and a connecting member 42. The connecting member 42 includes a vertical portion 421 and a horizontal portion 422. The vertical portion 421 extends along a first direction X, and the horizontal portion 422 extends along a third direction Z. The limit switch body 41 is connected to the vertical portion 421, and the horizontal portion 422 is connected to the horizontal structure 12.
[0093] In the non-collision state, the travel switch body 41 is spaced apart from the second portion 53 of the detection portion 50 along the first direction X. In the collision state, the first portion 51 of the detection portion 50 is in contact with the travel switch body 41 .
[0094] In some possible implementations, reference Figures 1 to 3 The vertical portion 421 is connected to the travel switch body 41 through a bolt 4211 . The vertical portion 421 includes four long holes 4212 . The length of the long holes 4212 is greater than the diameter of the bolt 4211 .
[0095] Using the above-mentioned technical solution, achieving absolutely precise dimensions during the production of connector 42 is difficult, and certain production errors may occur. To address this, the length of elongated hole 4212 is intentionally set to be greater than the diameter of bolt 4211 during the design of connector 42. Even if elongated hole 4212 is not precisely positioned, as long as the length of elongated hole 4212 is greater than the diameter of bolt 4211, the travel switch body 41 can still be accurately secured in the desired position, thus allowing for margin for error during the production of connector 42.
[0096] In some possible implementations, reference Figures 1 to 3 The anti-collision detection device includes a first limiter 70 disposed at the rear end of the slide rail 20 along the second direction Y. The first limiter 70 is disposed above the slide rail 20 along the first direction X. The bracket 10 includes a rectangular limiter structure 14 extending along the third direction Z. Both ends of the limiter structure 14 are connected to the vertical structure 11.
[0097] In the non-collision state, the first limiting member 70 contacts the limiting structure 14 along the second direction Y. In the collision state, the first limiting member 70 does not contact the limiting structure 14.
[0098] With the above technical solution, when the moving object moves away, the anti-collision detection device transitions from a collision state to a non-collision state, and the rebound force of the elastic member 60 acts on the slide rail 20, causing the slide rail 20 to slide back to its original position along the second direction Y. When the first limit member 70 contacts the limit structure 14, the sliding movement of the slide rail 20 is restricted. At this point, the slide rail 20 can no longer slide in the current direction, indicating that the slide rail 20 has returned to its original position. In other words, the travel switch 40 body is spaced apart from the second portion 53, and the slide rail 20 is prevented from separating from the slider 13.
[0099] It should be noted that the embodiment of the present application does not impose any specific restrictions on the shape of the limiting structure 14. For example, in other possible embodiments, the shape of the limiting structure 14 may be elliptical, trapezoidal, etc. The embodiment of the present application does not impose any specific restrictions on the specific structure of the first limiting member 70. For example, in other possible embodiments, the first limiting member 70 may be a bolt, a block, etc.
[0100] In some possible implementations, reference Figures 1 to 3 The anti-collision detection device includes a second limiter 80. The second limiter 80 is disposed at the front end of the slide rail 20 along the second direction Y and above the slide rail 20 along the first direction X. In the non-collision state, the second limiter 80 is spaced apart from the limit structure 14 along the second direction Y.
[0101] With the above technical solution, when a moving object collides with the anti-collision portion 30, the slide rail 20, under the action of the impact force, begins to drive the second limiter 80 to slide relative to the slider 13 in the second direction Y. During this process, the second limiter 80 gradually approaches the limit structure 14 as the slide rail 20 moves. When the second limiter 80 contacts the limit structure 14, the sliding movement of the slide rail 20 is restricted, and the slide rail 20 can no longer slide in the current direction, preventing the slide rail 20 from separating from the slider 13.
[0102] It should be noted that the embodiment of the present application does not impose any specific restrictions on the specific structure of the second limiting member 80. For example, in other possible implementations, the second limiting member 80 may be a bolt, a block, etc.
[0103] In some possible implementations, reference Figures 1 to 3 The anti-collision detection device includes a buffer member 90, which is disposed at the rear end of the slide rail 20 along the second direction Y and spaced apart from the first limiting member 70 along the third direction Z. In the non-collision state, the buffer member 90 contacts the limiting structure 14 along the second direction Y.
[0104] Using the above technical solution, when the moving object moves away, the anti-collision detection device transitions from a collision state to a non-collision state. The rebound force of the elastic member 60 acts on the slide rail 20, causing the slide rail 20 to slide back to its original position along the second direction Y. The rebound force generated by the elastic member 60 is often relatively large. Without the buffer member 90 to partially absorb the rebound force, the first limit member 70 would move rapidly along with the slide rail 20. Under such high-speed movement, the first limit member 70 would likely instantly collide with the limit structure 14. In this case, the impact force could easily cause serious damage to the limit structure 14, thereby affecting the normal function and service life of the entire anti-collision detection device.
[0105] It should be noted that the embodiment of the present application does not impose any specific restrictions on the specific structure of the buffer member 90. For example, in other possible implementations, the buffer member 90 may be a hydraulic cylinder, a spring, etc.
[0106] In some possible implementations, the anti-collision portion 30 is made of flexible rubber material.
[0107] By adopting the above technical solution, the rubber material can flexibly contact the person being hit or the moving object to prevent the person being hit from being injured.
[0108] It should be noted that the embodiment of the present application does not impose any specific restrictions on the specific type of the anti-collision part 30. For example, in other possible implementations, the anti-collision part 30 may be natural rubber, butadiene rubber, sponge, etc.
