Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to a vehicle. Background Art

[0002] Conventional vehicles have a frame that spans the front and rear axles, with wheels mounted on either end of the axles to enable normal vehicle operation. To improve the smoothness of vehicle operation, especially when navigating bumpy roads, the axles are connected to the frame via a suspension system. Common suspension systems, such as leaf spring suspension systems, allow the axles to move relative to the frame through the suspension system, cushioning the impact forces transmitted to the frame from bumpy roads. To prevent hard contact between the axles and the frame during relative movement and to prevent the suspension system from moving beyond a predetermined safe travel range, a limiting structure is typically provided on the axle or frame. The rubber blocks on the limiting structure come into contact with the axle or frame, limiting the movement of the suspension system and preventing hard contact between the axle and frame.

[0003] In the prior art, rubber blocks are mounted on the retaining members of the retaining structure through vulcanization. Over time, the rubber blocks wear out and age, and their thickness gradually decreases as they come into contact with the axle or frame while buffering deformation. If the rubber blocks fall off or become too thin, the retaining structure loses its cushioning capacity, causing the axle and frame to collide, damaging the axle or frame and shortening the service life of the frame and axle. Furthermore, the suspension system moves beyond its safe travel, causing damage and, in the case of leaf spring suspension systems, shortening the service life of the leaf spring system. Utility Model Content

[0004] The present application provides a vehicle to solve the technical problem that the buffer parts of the limiting structure wear out and lose their buffering ability, and cannot warn people that the buffer parts need to be replaced.

[0005] The technical solutions adopted in this application are:

[0006] A vehicle comprises an axle and a frame, wherein the axle is movably arranged relative to the frame, and further comprises: a limiting structure, wherein the limiting structure comprises a limiting member provided on one of the frame and the axle, and a buffer member connected to the limiting member; a sounding paddle; a triggering member movable relative to the limiting member, wherein the triggering member is provided with a toggle portion for toggling the sounding paddle to produce a sound, and the triggering member can move under the collision of the buffer member to toggle the sounding paddle to produce a sound through the toggle portion.

[0007] A vehicle in this application also includes the following additional technical features:

[0008] The limiting member has a limiting end connected to the buffer member, and a fixed end located on the side of the limiting end facing away from the buffer member and connected to the axle or the frame; the trigger member is slidably arranged on the limiting member to have an initial state and a trigger state for toggling the sounding paddle; the limiting end is provided with a through hole for the trigger member to move up and down.

[0009] The side where the buffer is connected to the limiting end is provided with an avoidance groove which is recessed toward a side away from the limiting member to avoid the triggering member. In the initial state, there is a collision avoidance gap between the triggering member and the avoidance groove.

[0010] The limiting member further includes a connecting arm connecting the limiting end and the fixed end, one end of the sounding pick is fixedly connected to the connecting arm, and the other end extends toward the trigger member.

[0011] The trigger member is provided with a stop portion. In the initial state, the stop portion abuts against the limit end to prevent the trigger member from being separated from the limit member.

[0012] The trigger member is provided with a plurality of toggling parts at intervals along its axial direction, and one of the toggling parts close to the limiting end constitutes the stopping part.

[0013] The trigger member has an initial state and a trigger state for tossing the sounding paddle. The trigger member is provided with a plurality of toggling parts at intervals along its axial direction, and an avoidance recess is formed between two adjacent toggling parts. In the trigger state, the trigger member moves to drive at least part of the toggling parts to abut against the sounding paddle one by one to toggle the sounding paddle to produce sound.

[0014] In the initial state, the toggle portion abuts against the sounding paddle, or an end of the sounding paddle close to the trigger member corresponds to the avoidance recess.

[0015] The trigger member includes a toggle section, an extension section connected to the toggle section and located on a side away from the buffer member, and a trigger section capable of contacting the buffer member. The toggle portion is provided on the toggle section. In the initial state, the projection of the toggle end of the sounding paddle toward the trigger member is located on the extension section.

[0016] The trigger member has an initial state and a trigger state of shifting the sound-generating paddle. The vehicle further includes a reset member, which is used to apply force to the trigger member so that the trigger member switches from the trigger state to the initial state.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. This application, by providing a limiter and a buffer, can limit the displacement of the axle relative to the frame, effectively preventing the suspension system connecting the axle and the frame from exceeding the safe movement range and being damaged. At the same time, by providing a buffer, hard contact between the axle and the frame can be avoided, the impact force of the axle on the frame can be buffered, and the stability of the vehicle can be improved. This application provides a sounding paddle and a triggering member that is movable relative to the limiter. The triggering member is provided with a toggle portion for toggling the sounding paddle. When the axle moves relative to the frame, the axle or frame contacts the buffer, the buffer can deform, and then can collide with the triggering member, so that the triggering member moves to drive the sounding paddle to sound. In one embodiment, as the buffer wears, the degree of deformation of the buffer increases, and the buffer reaches a warning value of maximum wear. The increase in deformation of the buffer can collide with the trigger part to move, driving the sounding paddle to make a sound, thereby reminding the driver that the buffer has reached the maximum wear value and needs to be replaced, so as to avoid the buffer being worn too thin, the buffering capacity of the buffer being insufficient, the impact force between the axle and the frame increasing, causing damage to the axle and frame, and the suspension system exceeding the movement range, causing damage to the suspension system.

[0019] 2. As a preferred embodiment of the present application, a limit end and a fixed end are provided, and a trigger member is provided that can slide up and down on the limit member. Because the axle moves up and down relative to the frame, the impact force on the buffer mainly comes from the vertical direction. Due to the restriction of the limit end, the buffer is flattened by the impact of the frame or axle, and the deformation in the left and right directions is large, and the thickness of the buffer becomes thinner. As the buffer wears, the degree of deformation of the buffer under force increases, and the thickness of the buffer becomes thinner after the force deformation. Therefore, the up and down sliding of the trigger member can more directly be hit by the buffer. At the same time, it can more directly reflect the current thickness of the buffer and reflect the buffer's buffering capacity. After reaching a preset warning value, the trigger member toggles the sounding paddle to sound, reminding the driver to replace the buffer. By setting the trigger member to have an initial state for sliding up and down, and a trigger state for toggling the sounding paddle, the trigger member can toggle the sounding paddle during the up and down sliding process, and the sounding paddle can provide timely feedback. A through hole is provided at the limit end for the trigger to move, and the limit end is connected to the buffer. When the buffer is worn to the warning value, the buffer can collide with the trigger more directly to make the sounding pick sound, thereby improving the accuracy of the sounding pick.

[0020] 3. As a preferred embodiment of the present application, a clearance groove is provided to avoid the trigger member, allowing the trigger member to partially reside in the clearance groove. When the buffer member is impacted by the axle or frame, the buffer member will have a tendency to deform in multiple directions. The clearance groove provides a margin for the trigger member to erroneously contact, preventing malfunction of the trigger member when the buffer member has sufficient buffering capacity, thereby improving the accuracy of the sounding pick. By providing a collision avoidance gap, the disturbance of the trigger member to the buffer member when it has sufficient buffering capacity can be reduced. The thickness warning value of the buffer member can also be adjusted by controlling the size of the collision avoidance gap, thereby improving the accuracy of the sounding pick.

[0021] Furthermore, by setting a connecting arm, one end of the sounding pick is fixedly connected to the connecting arm, and the other end extends toward the trigger member. The structure and setting method of the sounding pick and the trigger member are simple, easy to design, manufacture and install, and also more convenient for the trigger member to move the sounding pick to make a sound.

[0022] 4. As a preferred embodiment of the present application, the trigger member is provided with a stop portion. By setting the stop portion to abut against the limit end, the trigger member can be prevented from detaching from the limit member, thereby improving the stability of the trigger member and keeping the trigger member in its initial state.

[0023] Furthermore, by providing multiple toggle parts, the frequency of toggling the sounding pick is increased, making the sound of the sounding pick more continuous and more obvious, which helps the driver to notice it. At the same time, by providing a toggle part near the limit end to form a stop part, it achieves multiple functions, avoids the design and manufacturing costs of providing a separate stop part, and realizes a compact layout of the limit structure.

[0024] 5. As a preferred embodiment of the present application, by providing multiple toggle parts, the frequency of toggling the sounding paddle is increased, making the sound of the sounding paddle more continuous and more obvious, which helps the driver to detect it. By providing an avoidance recess, the force of the toggle part's toggling of the sounding paddle can be controlled. By providing a trigger member that moves to drive some of the toggle parts into contact with the sounding paddle, the sound effect of the sounding paddle is further ensured, which helps the driver to detect it.

[0025] Furthermore, by arranging the toggle portion to abut against the sounding paddle, the toggle portion drives the sounding paddle more directly, causing the sounding paddle to sound in a timely manner. By aligning the end of the sounding paddle close to the trigger member with the avoidance recess, the toggle portion increases the toggle amplitude of the sounding paddle, improves the toggle effect of the toggle portion on the sounding paddle, and makes it easier to alert the driver.

[0026] 5. As a preferred embodiment of the present application, by providing an extension section, in the initial state, the projection of the end of the sound - generating flap that is to be toggled onto the trigger member is located on the extension section. The sound - generating flap needs to pass through the extension section before it can be toggled by the toggling section, which improves the anti - interference ability of the sound - generating flap. This avoids the mis - operation of the trigger member causing the sound - generating flap to sound when the buffer member has buffering ability, and improves the accuracy of the sound - generating flap.

[0027] 6. As a preferred embodiment of the present application, by providing a reset member, a force can be applied to the trigger member to switch the trigger member from the triggered state to the initial state. On the one hand, it enables the trigger member to automatically reset after being triggered, improving the applicability of the trigger member, realizing the repeated triggering of the trigger member, avoiding the driver not noticing a single trigger, and improving the warning effect. On the other hand, during the reset process of the trigger member, the toggling portion can toggle the sound - generating flap again, prolonging the sound of the sound - generating flap, and thus improving the warning effect of the sound - generating flap.

[0037] To more clearly illustrate the overall concept of the present application, the following is a detailed description by way of example in conjunction with the drawings of the specification.

[0038] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application may also be implemented in other ways than those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features of each embodiment may be combined with each other unless there is a conflict.

[0039] like Figure 1 As shown, a vehicle includes an axle and a frame, the axle is movably arranged relative to the frame, and also includes a limiting structure, the limiting structure includes a limiting member 1 provided on one of the frame and the axle, and a buffer member 2 connected to the limiting member 1; a sounding paddle 3; a trigger member 4 movable relative to the limiting member 1, the trigger member 4 is provided with a toggle portion 41 for toggle the sounding paddle 3 to make a sound, and the trigger member 4 can move under the collision of the buffer member 2 to toggle the sounding paddle 3 to make a sound through the toggle portion 41.

[0040] By providing a limiter 1 and a buffer 2, the present application can limit the displacement of the axle relative to the frame, effectively preventing the suspension system connecting the axle and the frame from exceeding the safe movement range and being damaged. At the same time, by providing the buffer 2, hard contact between the axle and the frame can be avoided, the impact force of the axle on the frame can be buffered, and the stability of the vehicle can be improved. The present application provides a sounding paddle 3 and a trigger 4 that is movable relative to the limiter 1. The trigger 4 is provided with a toggle portion 41 for toggling the sounding paddle 3. When the axle moves relative to the frame, the axle or frame contacts the buffer 2, and the buffer 2 can deform, thereby colliding with the trigger 4, so that the trigger 4 moves and drives the sounding paddle 3 to sound. In one embodiment, as the buffer 2 wears, the deformation of the buffer 2 increases, and the buffer 2 reaches the warning value of maximum wear. The increase in the deformation of the buffer 2 can collide with the trigger 4 to move, driving the sound-generating paddle 3 to make a sound, thereby reminding the driver that the buffer 2 has reached the maximum wear value and needs to be replaced, so as to avoid the buffer 2 being worn too thin, the buffering capacity of the buffer 2 being insufficient, the impact force between the axle and the frame being increased, causing damage to the axle and the frame, and the suspension system exceeding the movement range, causing damage to the suspension system. It is clear to those skilled in the art that the buffer 2 can be made of rubber material or other materials that can be elastically deformed. The sound-generating paddle 3 is moved to make a sound, which can be as follows Figure 1 The sheet structure shown, or other structures that can make sounds when collided, etc., are not limited in this application. It is clear to those skilled in the art that the warning value of the buffer 2 belongs to the thickness of the buffer 2. When the wear thickness of the buffer 2 reaches the warning value, the deformation of the buffer 2 can collide with the trigger part 4.

[0041] In this application, the trigger member 4 may be configured in any of the following ways:

[0042] Implementation method 1: Figure 1As shown, the limit member 1 has a limit end 11 connected to the buffer member 2, and a fixed end 12 located on the side of the limit end 11 facing away from the buffer member 2 and connected to the axle or frame; the trigger member 4 is slidably arranged on the limit member 1 so as to have an initial state and a trigger state for toggling the sounding paddle 3; the limit end 11 is provided with a through hole 111 for the trigger member 4 to move up and down.

[0043] By providing a limit end 11 and a fixed end 12, the trigger member 4 is configured to slide up and down on the limit member 1. As the axle moves up and down relative to the vehicle frame, the impact force on the buffer 2 primarily comes from the vertical direction. Due to the restriction of the limit end 11, the buffer 2 is flattened by the impact of the vehicle frame or axle, deforming significantly to the left and right, and the thickness of the buffer 2 decreases. As the buffer 2 wears, the degree of deformation caused by the force increases, and the thickness of the buffer 2 further decreases after the force deformation. Therefore, the up and down sliding of the trigger member 4 can more directly impact the buffer 2. At the same time, it can more directly reflect the current thickness of the buffer 2 and the buffering capacity of the buffer 2. When the preset warning value is reached, the trigger member 4 activates the sounding paddle 3 to produce a sound, reminding the driver to replace the buffer 2. By providing an initial state for the up and down sliding of the trigger member 4 and a trigger state for the sounding paddle 3, the trigger member 4 can activate the sounding paddle 3 during the up and down sliding process, and the sounding paddle 3 can provide timely feedback. A through hole 111 is provided at the limit end 11 for the trigger member 4 to move, and the limit end 11 is connected to the buffer member 2. When the buffer member 2 is worn to the warning value, the buffer member 2 can collide with the trigger member 4 more directly to make the sounding pick 3 sound, thereby improving the accuracy of the sounding pick 3.

[0044] In the first embodiment, the buffer member 2 may be arranged in any of the following ways:

[0045] Example 1: Figure 1 As shown, the side of the buffer 2 connected to the limit end 11 is provided with an avoidance groove 21 that is recessed toward the side away from the limit member 1 to avoid the trigger member 4. When the buffer 2 is hit by the axle or frame, the buffer 2 will have a tendency to deform in multiple directions. The avoidance groove 21 provides space for the trigger member 4 to touch the ground accidentally, preventing the trigger member 4 from malfunctioning when the buffer 2 has sufficient buffering capacity, thereby improving the accuracy of the sounding pick 3. By setting a collision avoidance gap, the disturbance of the trigger member 4 by the buffer 2 when it has sufficient buffering capacity can be reduced. The size of the collision avoidance gap can also be controlled to adjust the thickness warning value of the buffer 2, thereby improving the accuracy of the sounding pick 3.

[0046] In embodiment 1, after the buffer member 2 falls off, the trigger member 4 can still be moved up and down by the axle or the frame abutting against the trigger member 4 to drive the sounding pick 3 to make a sound.

[0047] In Example 1, the configuration of the sounding pick 3 can be any one of the following specific examples:

[0048] Specific example 1: if Figure 1 As shown, the limiter 1 further includes a connecting arm 13 connecting the limiter end 11 and the fixed end 12, one end of the sounding pick 3 is fixedly connected to the connecting arm 13, and the other end extends toward the triggering member 4. As a preferred embodiment, Figure 1 、 Figure 2 As shown, the sounding pick 3 is arranged to extend horizontally, as shown in FIG. Figure 1 、 Figure 2 By providing a connecting arm 13, one end of the sounding pick 3 is fixedly connected to the connecting arm 13, and the other end extends toward the trigger member 4. The structure and setting method of the sounding pick 3 and the trigger member 4 are simple, easy to design, manufacture and install, and also more convenient for the trigger member 4 to move the sounding pick 3 to produce sound.

[0049] Specific example 2: This specific example 2 is not shown in the figure, the sounding pick 3 is connected to the limit end 11 or the fixed end 12, and has one end extending toward the trigger member 4. As an example, the sounding pick 3 is connected to the fixed end 12 and has an L-shaped structure.

[0050] It is clear to those skilled in the art that the sounding paddle 3 can be set as in Specific Example 1 or Specific Example 2, or one end can be connected to the limiting end 11 and the other end can be connected to the fixed end 12. The sounding paddle 3 is also provided with an end extending toward the trigger member 4, and the sounding paddle 3 is T-shaped.

[0051] Embodiment 2: This embodiment 2 is not shown in the figure. The limiting end 11 is provided with a receiving groove. The receiving groove is provided with a through hole 111 for the trigger member 4 to move up and down. There is a collision avoidance gap between the trigger member 4 and the buffer member 2. When the thickness of the buffer member 2 is reduced and the degree of deformation is increased, in the event of a collision with the axle or the frame, the buffer member 2 can enter the receiving groove and collide with the trigger member 4, causing the trigger member 4 to move up and down and drive the sounding paddle 3 to make a sound.

[0052] In a preferred embodiment of the embodiment below, as Figure 1 As shown, the trigger member 4 is provided with a stop portion 42 . In the initial state, the stop portion 42 abuts against the limiting end 11 to prevent the trigger member 4 from being separated from the limiting member 1 .

[0053] The trigger member 4 is provided with a stopper 42 , which abuts against the limit end 11 to prevent the trigger member 4 from detaching from the limit member 1 , thereby improving the stability of the trigger member 4 and keeping the trigger member 4 in its initial state.

[0054] In this embodiment, the stopper 42 may be provided in any of the following specific examples:

[0055] Specific example 3: ifFigure 1 、 Figure 2 As shown, the trigger member 4 is provided with a plurality of toggling portions 41 at intervals along its axial direction, and a toggling portion 41 close to the limiting end 11 constitutes a stop portion 42 .

[0056] By providing multiple toggle portions 41, the frequency of toggling the sounding paddle 3 is increased, making the sounding paddle 3 sound more continuous and more obvious, which helps the driver to notice it. At the same time, by providing a toggle portion 41 near the limit end 11 to form the stop portion 42, a multi-purpose device is achieved, avoiding the design and manufacturing costs of providing a separate stop portion 41, and achieving a compact limit structure layout.

[0057] Specific example 4: This specific example 4 is not shown in the figure. The trigger member 4 is provided with a stop portion 42, and the stop portion 42 can abut the limit end 11. The trigger member 4 is also provided with a plurality of toggle portions 41 at intervals. A toggle portion 41 close to the limit end 11 is spaced apart from the stop portion 42. By providing the stop portion 42, hard contact between the toggle portion 41 and the limit end 11 can be avoided during movement, thereby protecting the toggle portion 41 and extending the service life of the toggle portion 41.

[0058] Embodiment 2: This embodiment 2 is not shown in the figure. The limiter 1 has a limit end 11 connected to the buffer 2, and a fixed end 12 located on the side of the limit end 11 facing away from the buffer 2 and connected to the axle or frame. The trigger 4 is arranged on the left or right side of the buffer 2. The trigger 4 can be arranged on the limiter 1 so as to move horizontally. The buffer 2 is deformed laterally by the collision of the frame or the axle. When the buffer 2 is worn to the warning value, the thickness of the buffer 2 becomes thinner, the degree of lateral deformation increases, and thus drives the trigger 4 to move laterally. At this time, the sounding paddle 3 is vertically arranged at the fixed end 12. The trigger 4 is a 匚-shaped structure. The limit end 11 is provided with a guide groove for guiding the lateral movement of one end of the 匚-shaped structure.

[0059] It is clear to those skilled in the art that the trigger member 4 can be Figure 1 The cylindrical structure in the figure can also be a square or special-shaped structure such as a 匚-shaped structure, which is not limited in this application.

[0060] As a preferred embodiment of the present application, Figure 1 As shown, the trigger member 4 has an initial state and a trigger state for toggling the sounding pick 3, as shown in FIG. Figure 1As shown, the trigger member 4 is in its initial state. The trigger member 4 is provided with a plurality of toggling portions 41 spaced along its axial direction, and an avoidance recess 43 is formed between two adjacent toggling portions 41. In the triggered state, the trigger member 4 moves to drive at least some of the toggling portions 41 to abut against the sounding paddle 3 one by one to toggle the sounding paddle 3 to produce a sound. By providing a plurality of toggling portions 41, the frequency of toggling the sounding paddle 3 is increased, making the sound of the sounding paddle 3 more continuous and more obvious, which helps the driver to notice. By providing the avoidance recess 43, the force with which the toggling portion 41 toggles the sounding paddle 3 can be controlled. By providing the trigger member 4 to move to drive some of the toggling portions 41 to abut against the sounding paddle 3, the sound effect of the sounding paddle 3 is further ensured, which helps the driver to notice.

[0061] It is clear to those skilled in the art that the trigger member 4 can be provided with a protrusion extending in the axial direction of the trigger member 4 , and the trigger member 4 is provided in such a manner that avoidance recesses 43 are spaced apart on the protrusion and two adjacent avoidance recesses 43 form a toggle portion 41 .

[0062] In this embodiment, in the initial state, as Figure 1 As shown, the arrangement of the paddle portion 41 and the sounding paddle 3 can be any one of the following embodiments:

[0063] Embodiment 3: In the initial state, the toggle portion 41 is in contact with the sounding paddle 3. By setting the toggle portion 41 in contact with the sounding paddle 3, the toggle portion 41 drives the sounding paddle 3 more directly, so that the sounding paddle 3 makes a sound in time.

[0064] Example 4: The end of the sounding paddle 3 closest to the trigger 4 corresponds to the avoidance recess 43. By aligning the end of the sounding paddle 3 closest to the trigger 4 with the avoidance recess 43, the amplitude and effect of the toggle portion 41 on the sounding paddle 3 are increased, making it easier for the driver to notice.

[0065] In this application, the toggle portion 41 may be as follows: Figure 1 、 Figure 2 As shown, the annular protrusion provided on the trigger member 4 can also be a sheet-shaped or block-shaped protrusion extending toward the side where the sounding pick 3 is located. The number of sounding picks 3 provided can be one or more. Figure 1 The middle trigger member 4 can be provided with a sounding paddle 3 in all directions around it to increase the sound volume of the sounding paddle 3 and the warning effect, which is more helpful for the driver to notice.

[0066] As a preferred embodiment of this embodiment, Figure 1 、 Figure 2As shown, the trigger member 4 includes a toggle section 44, an extension section (not shown in the drawings) connected to the toggle section 44 and located on the side away from the buffer member 2, and a trigger section 45 that can contact the buffer member 2. The toggle portion 41 is provided on the toggle section 44. In the initial state, the projection of the toggle end of the sounding paddle 3 toward the trigger member 4 is located on the extension section. The extension section can extend toward the fixed end 12. Along the axial direction of the trigger member 4, the extension section, the toggle section 44, and the trigger section 45 are arranged in sequence. It is clear to those skilled in the art that, in this embodiment, the buffer member 2 can be spaced apart from the trigger section 45 to further improve the accuracy of the collision trigger member 4, while also facilitating personnel to adjust the thickness warning value of the buffer member 2.

[0067] By setting the extension section, in the initial state, the projection of the end of the sounding pick 3 that is plucked toward the trigger member 4 is located in the extension section. The sounding pick 3 needs to pass through the extension section before it can be plucked by the plucking section 44, thereby improving the anti-interference ability of the sounding pick 3 and avoiding the trigger member 4 from malfunctioning and causing the sounding pick 3 to sound when the buffer member 2 has the buffering capacity, thereby improving the accuracy of the sounding pick 3.

[0068] As a preferred embodiment of the present application, Figure 1 、 Figure 2 As shown, the trigger member 4 has an initial state and a trigger state of the sounding paddle 3, and the vehicle further includes a reset member 5, which is used to apply force to the trigger member 4 to switch the trigger member 4 from the trigger state to the initial state. It is clear to those skilled in the art that the reset member 5 can be as follows Figure 1 、 Figure 2 The reset spring provided in the embodiment can also be a rubber block made of elastic material, etc., and this application does not limit this. By providing the reset member 5, a force can be applied to the trigger member 4, causing the trigger member 4 to switch from the triggered state to the initial state. On the one hand, the trigger member 4 can automatically reset after being triggered, improving the applicability of the trigger member 4, enabling repeated triggering of the trigger member 4, avoiding the driver's perception of the triggering, and improving the warning effect. On the other hand, during the reset process of the trigger member 4, the toggle portion 41 can toggle the sounding paddle 3 again, prolonging the sounding of the sounding paddle 3, thereby improving the warning effect of the sounding paddle 3.

[0069] It is clear to those skilled in the art that when the limiter 1 is set on the vehicle frame and the trigger 4 is arranged vertically downward, the trigger 4 can be reset by its own gravity, which can save the use of the reset member 5. The present application also provides a reference for the separate arrangement of the buffer 2 and the limiter 1. One of the limiter 1 and the buffer 2 is set on the axle, and the other is set on the frame. An avoidance groove 21 is set on the limiter 1 or the buffer 2, so that when the thickness of the buffer 2 becomes thinner and reaches the warning value, the frame or axle collides with the buffer 2, and the buffer 2 drives the trigger 4 to operate. At the same time, it can make it easier to maintain and replace the limiter 1 and the buffer 2 in the future.

[0070] Those not described in this application can be implemented by adopting or referring to the prior art.

[0071] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the key points of each embodiment are the differences from other embodiments.

[0072] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, various changes and modifications can be made to this application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.

A vehicle, the vehicle comprising an axle and a vehicle frame, the axle being movably arranged relative to the vehicle frame, characterized in that: Also includes: A limiting structure, the limiting structure comprising a limiting member provided on one of the vehicle frame and the vehicle axle, and a buffer member connected to the limiting member; sounding picks; A triggering member is movable relative to the limiting member, and the triggering member is provided with a toggling portion for toggling the sound-generating pick to produce sound. The triggering member can move under the collision of the buffer member to toggle the sound-generating pick to produce sound through the toggling portion.

2. A vehicle according to claim 1, characterized in that: The limiting member has a limiting end connected to the buffer member, and a fixed end located on the side of the limiting end facing away from the buffer member and connected to the axle or the frame; the trigger member is slidably arranged on the limiting member to have an initial state and a trigger state for toggling the sounding paddle; the limiting end is provided with a through hole for the trigger member to move up and down.

3. A vehicle according to claim 2, characterized in that: The side where the buffer is connected to the limiting end is provided with an avoidance groove which is recessed toward a side away from the limiting member to avoid the triggering member. In the initial state, there is a collision avoidance gap between the triggering member and the avoidance groove.

4. A vehicle according to claim 3, characterized in that: The limiting member further includes a connecting arm connecting the limiting end and the fixed end, one end of the sounding pick is fixedly connected to the connecting arm, and the other end extends toward the trigger member.

5. The vehicle according to claim 2, characterized in that: The trigger member is provided with a stop portion. In the initial state, the stop portion abuts against the limit end to prevent the trigger member from being separated from the limit member.

6. A vehicle according to claim 5, characterized in that: The trigger member is provided with a plurality of toggling parts at intervals along its axial direction, and one of the toggling parts close to the limiting end constitutes the stopping part.

7. The vehicle according to claim 1, characterized in that: The trigger member has an initial state and a trigger state for tossing the sounding paddle. The trigger member is provided with a plurality of toggling parts at intervals along its axial direction, and an avoidance recess is formed between two adjacent toggling parts. In the trigger state, the trigger member moves to drive at least part of the toggling parts to abut against the sounding paddle one by one to toggle the sounding paddle to produce sound.

8. A vehicle according to claim 7, characterized in that: In the initial state, the toggle portion abuts against the sounding paddle, or an end of the sounding paddle close to the trigger member corresponds to the avoidance recess.

9. The vehicle according to claim 7, characterized in that: The trigger member includes a toggle section, an extension section connected to the toggle section and located on a side away from the buffer member, and a trigger section capable of contacting the buffer member. The toggle portion is provided on the toggle section. In the initial state, the projection of the toggle end of the sounding paddle toward the trigger member is located on the extension section.

10. The vehicle according to claim 1, characterized in that: The trigger member has an initial state and a trigger state of shifting the sound-generating paddle. The vehicle further includes a reset member, which is used to apply force to the trigger member so that the trigger member switches from the trigger state to the initial state.
