Technical Field

[0001] This invention relates to the field of traffic control technology, and in particular to a method for limiting the speed of non-motorized vehicles and a speed limit device for non-motorized vehicles. Background Technology

[0002] Speeding is a common phenomenon when non-motorized vehicles are in motion, especially among electric bicycles.

[0003] Speeding often poses safety hazards, especially in confined spaces such as tunnels and bridges, where these traffic safety risks can be significant.

[0004] Therefore, various measures are needed to limit the speed of non-motorized vehicles to a safe range. In key road sections such as tunnels and bridges, physical speed limit devices should also be installed.

[0005] However, the aforementioned physical speed limiting device does not exist in the existing technology.

[0006] Therefore, how to implement physical speed limits on non-motorized vehicle lanes has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of the above-mentioned deficiencies of the prior art, the present invention provides a method for limiting the speed of non-motorized vehicles and a speed limit lever device for limiting the speed of non-motorized vehicles. The purpose is to use a telescopic lever to move along the direction of travel at the maximum speed limit of non-motorized vehicles, so as to block non-motorized vehicles that exceed the speed limit and allow vehicles behind to follow below the speed limit.

[0008] To achieve the above objectives, this invention discloses a method for limiting the speed of non-motorized vehicles; used to control the extension and retraction of each telescopic barrier installed on one side of the non-motorized vehicle lane, comprising the following steps:

[0009] Step 1: When the speed limiting device including the telescopic lever is activated, control all the telescopic levers to retract;

[0010] Step 2: Detect whether all the telescopic barriers are on the straight guide rail moving in the forward direction along the corresponding non-motorized vehicle lane or on the straight guide rail moving in the reverse direction along the corresponding non-motorized vehicle lane.

[0011] For each telescopic barrier that is moving along the straight guide rail in the positive direction of the corresponding non-motorized vehicle lane, step 2.A1 is performed;

[0012] For each telescopic stop that is moving in the opposite direction along the corresponding non-motorized vehicle lane, step 2.B1 is performed;

[0013] Step 2.A1: The telescopic lever is in a forward motion state;

[0014] Step 2.A2: Check whether there are people or obstacles in the front and rear safety zones of the telescopic barrier;

[0015] If there are people or obstacles in the safety zone in front of or behind the telescopic barrier, then the telescopic barrier is retracted, or the telescopic barrier is kept in the retracted state, and step 2.A2 is repeated.

[0016] If there are no people or obstacles in the safety zone in front of and behind the telescopic barrier, then extend the telescopic barrier, or keep the telescopic barrier extended, and proceed with the subsequent steps.

[0017] Step 2.A3: Detect whether there is a stopped, slow-moving, or reversing object in front of the telescopic barrier;

[0018] If there is a stopped, slow-moving, or reversing object in front of the telescopic barrier, then retract the telescopic barrier and repeat steps 2.A2 to 2.A3.

[0019] If there are no stopped, slow-moving, or reversing objects in front of the telescopic barrier, the telescopic barrier remains extended, and subsequent steps are executed.

[0020] Step 2.A4: Detect whether the telescopic stop is on the straight guide rail that is moving forward relative to the corresponding non-motorized vehicle lane;

[0021] If so, repeat steps 2.A1 to 2.A4;

[0022] If not, proceed to steps 2.B1 to 2.B3;

[0023] Step 2.B1: The telescopic lever is in the reverse motion state;

[0024] Step 2.B2: Retract the telescopic lever, or keep the telescopic lever in its retracted state;

[0025] Step 2.B3: Detect whether the telescopic stop is on the straight guide rail that moves in the opposite direction to the corresponding non-motorized vehicle lane;

[0026] If so, repeat steps 2.B2 to 2.B3;

[0027] If not, proceed with steps 2.A1 to 2.A4.

[0028] Preferably, the moving speed of each of the telescopic barriers is the maximum speed limit of the non-motorized vehicle lane.

[0029] The present invention also provides a speed limit device for non-motorized vehicles, for implementing the above-described speed limit method for non-motorized vehicles, comprising a track disposed on one side of the non-motorized vehicle lane, a plurality of base plates disposed on the track and movable along the track, and a telescopic speed limit device disposed on each of the base plates.

[0030] Preferably, each of the telescopic levers includes a transverse cantilever telescopic lever formed by multiple sets of hinged four-bar linkages connected in sequence, and an identification plate set at the suspended end of the corresponding transverse cantilever telescopic lever.

[0031] Each of the transverse cantilever telescopic rods has two suspended ends of a set of four-bar linkages closest to the corresponding base plate that are hinged to two sliders on the corresponding base plate. The linkage extends when the distance between the two sliders decreases and retracts when the distance between the two sliders increases.

[0032] Preferably, each of the substrates is provided with a detection device facing the start and end points of the corresponding non-motorized vehicle lane.

[0033] Preferably, the track includes an inner ring track and an outer ring track that are similar in shape and both have an elongated hole shape;

[0034] Both the inner and outer ring tracks include two parallel straight guide rails and turning guide rails located at both ends;

[0035] Each of the substrates is provided with rollers on the inner side of the inner ring track and on the outer side of the outer ring track, which are capable of locking the inner ring track or the outer ring track at the corresponding positions.

[0036] A mechanical drive chain is provided between the inner ring track and the outer ring track;

[0037] The mechanical drive chain is a pulley mechanism driven by two belts, a two-mechanism driven by two sprockets, or a synchronous belt mechanism driven by two synchronous pulleys. The corresponding V-belts, chains, or synchronous belts are all arranged along the elongated oval gap between the inner ring track and the outer ring track.

[0038] Each of the substrates is connected to the corresponding V-belt, chain, or timing belt via a cable clamp at the position facing the gap between the inner and outer ring tracks, and is driven to move along the tracks by the corresponding V-belt, chain, or timing belt.

[0039] Preferably, each substrate is provided with a plurality of rollers capable of engaging the inner or outer ring track at the corresponding positions on the inner side of the inner ring track and the outer side of the outer ring track.

[0040] Each of the aforementioned turning guide rails meets the requirements for passing through curves, that is, the gauge of the arc segment is slightly smaller than the gauge of the corresponding straight guide rail. The specific reduction in width must be calculated and determined based on the component size and turning radius.

[0041] More preferably, each of the curved guide rails has a transition curve between its arc segment and the corresponding straight guide rail.

[0053] Example

[0054] like Figure 1 As shown, the method for limiting the speed of non-motorized vehicles; used to control the extension and retraction of each telescopic barrier 3 installed on one side of the non-motorized vehicle lane, which reciprocates, includes the following steps:

[0055] Step 1: When the speed limiting device, including the telescopic gear lever 3, is activated, control all telescopic gear levers 3 to retract.

[0056] Step 2: Check whether all telescopic barrier bars 3 are on the straight guide rail moving forward along the corresponding non-motorized vehicle lane or on the straight guide rail moving backward along the corresponding non-motorized vehicle lane.

[0057] For each telescopic barrier 3 that is moving along the straight guide rail in the positive direction of the corresponding non-motorized vehicle lane, step 2.A1 is executed;

[0058] For each telescopic stop 3 that is moving in the opposite direction along the corresponding non-motorized vehicle lane on the straight guide rail, step 2.B1 is executed.

[0059] Step 2.A1, Telescopic lever 3 is in the forward motion state;

[0060] Step 2.A2: Check whether there are people or obstacles in the front and rear safety zones of the telescopic barrier 3;

[0061] If there are people or obstacles in the safety zone in front of and behind the telescopic barrier 3, then retract the telescopic barrier 3, or keep the telescopic barrier 3 in the retracted state and repeat step 2.A2.

[0062] If there are no people or obstacles in the safety zone in front of and behind the telescopic barrier 3, extend the telescopic barrier 3, or keep the telescopic barrier 3 in the extended state and proceed with the next steps.

[0063] Step 2.A3: Check if there are any stopped, slow-moving, or reversing objects in front of the telescopic lever 3;

[0064] If there is a stopped, slow-moving, or reversing object in front of the telescopic lever 3, then retract the telescopic lever 3 and repeat steps 2.A2 to 2.A3.

[0065] If there are no stopped, slow-moving, or reversing objects in front of the telescopic gear lever 3, keep the telescopic gear lever 3 in the extended state and proceed with the next steps.

[0066] Step 2.A4: Check whether the telescopic stop is on the straight guide rail that is moving in the positive direction relative to the corresponding non-motorized vehicle lane;

[0067] If so, repeat steps 2.A1 to 2.A4;

[0068] If not, proceed to steps 2.B1 to 2.B3;

[0069] Step 2.B1, the telescopic lever 3 is in the reverse motion state;

[0070] Step 2.B2: Retract the telescopic lever 3, or keep the telescopic lever 3 in the retracted state;

[0071] Step 2.B3: Check whether the telescopic stop is on the straight guide rail that moves in the opposite direction to the corresponding non-motorized vehicle lane;

[0072] If so, repeat steps 2.B2 to 2.B3;

[0073] If not, proceed with steps 2.A1 to 2.A4.

[0074] In some embodiments, the moving speed of each telescopic lever 3 is the maximum speed limit of the non-motorized vehicle lane.

[0075] In this invention, the telescopic lever 3 moves forward in the direction of non-motorized vehicle riding at a set speed limit on the straight guide rail that moves forward relative to the corresponding non-motorized vehicle lane in the extended state. After switching to the straight guide rail that moves in the opposite direction relative to the corresponding non-motorized vehicle lane, it switches to the retracted state; and then returns in the retracted state along the straight guide rail that moves in the opposite direction relative to the corresponding non-motorized vehicle lane.

[0076] During this process, when it is detected that there are no people or obstacles nearby, the telescopic lever 3 extends outward and switches to the extended state;

[0077] When the telescopic barrier 3 moves forward along the direction of non-motorized vehicle riding on the straight guide rail that moves forward relative to the corresponding non-motorized vehicle lane, if it detects a person or object that is stationary, moving slowly, or moving in the opposite direction in front, the telescopic barrier 3 will automatically retract to avoid collision. When it detects again that there are no obstacles or people within the safe range in front and behind, the telescopic barrier 3 will extend outward again.

[0078] like Figures 2 to 7 As shown, the present invention also provides a speed limit device for non-motorized vehicles, used to implement the above-mentioned speed limit method for non-motorized vehicles, including a track 1 set on one side of the non-motorized vehicle lane, a plurality of base plates 2 set on the track 1 and capable of moving along the track 1, and a telescopic stop bar 3 set on each base plate 2.

[0079] In some embodiments, each telescopic lever 3 includes a transverse cantilever telescopic lever 32 formed by multiple sets of hinged four-bar linkages 31 connected in sequence, and an identification plate 33 set at the suspended end of the corresponding transverse cantilever telescopic lever 32.

[0080] Each transverse cantilever telescopic rod 32 has two suspended ends of a set of four-bar linkages 31 closest to the corresponding base plate 2, which are respectively hinged to two sliders 22 on the corresponding base plate 2. The rod extends when the distance between the two sliders 22 decreases and retracts when the distance between the two sliders 22 increases.

[0081] In this invention, the transverse cantilever telescopic rod 32, which is formed by connecting multiple sets of hinged four-bar linkages 31 in sequence, is installed on the groove 21 of the corresponding base plate 2, which includes two sliders 22. The two suspended ends are respectively hinged to the two sliders 22 on the corresponding base plate 2. The extension and retraction of the transverse cantilever telescopic rod 32 is realized by sliding the two sliders 22.

[0082] In some embodiments, each substrate 2 is provided with a detection device 23 facing the start and end points of the corresponding non-motorized vehicle lane.

[0083] In some embodiments, track 1 includes an inner ring track 11 and an outer ring track 12 that are similar in shape and both have an elongated hole shape;

[0084] Both the inner ring track 11 and the outer ring track 12 include two parallel straight guide rails and turning guide rails located at both ends;

[0085] Each substrate 2 is provided with rollers 25 on the inner side of the corresponding inner ring track 11 and the outer side of the corresponding outer ring track 12, which can lock the inner ring track 11 or the outer ring track 12 at the corresponding position.

[0086] A mechanical drive chain is provided between the inner ring track 11 and the outer ring track 12;

[0087] The mechanical drive chain is a pulley mechanism driven by two belts, a two-mechanism driven by two sprockets, or a synchronous belt mechanism driven by two synchronous pulleys. The corresponding V-belt, chain, or synchronous belt 13 is set along the elongated oval gap between the inner ring track 11 and the outer ring track 12.

[0088] Each substrate 2 is connected to the corresponding V-belt, chain, or synchronous belt 13 at the position facing the gap between the inner ring track 11 and the outer ring track 12 via a cable clamp, and is driven to move along the track 1 by the corresponding V-belt, chain, or synchronous belt 13.

[0089] The base of the present invention is mounted on the track 1 by two rollers 25 that can respectively engage the inner ring track 11 and the outer ring track 12, and can slide along the track 1;

[0090] The base is connected to the corresponding V-belt, chain or timing belt 13 via cable clamps, and moves along the track 1 by the movement of the corresponding V-belt, chain or timing belt 13.

[0091] In some embodiments, each substrate 2 is provided with a plurality of rollers 25 on the inner side of the corresponding inner ring track 11 and the outer side of the corresponding outer ring track 12, which can lock the inner ring track 11 or the outer ring track 12 at the corresponding positions.

[0092] At each turn, the guide rail meets the turning requirements, that is, the gauge of the arc segment is less than the gauge of the straight segment. In this example, with an inner radius of 380mm for the turn, a gauge of 390mm for the straight segment, and a turning angle of 180 degrees, the narrowest gauge at the turn is 335mm.

[0093] In some embodiments, a transition curve is provided between the arc segment of each turning guide rail and the corresponding straight guide rail.

[0094] The presence of a transition curve can minimize the difference in track distance between the front and rear of substrate 2.

[0095] In some embodiments, a spring is provided between the roller 25 of each substrate 2 and the corresponding substrate 2.

[0096] In practical applications, the presence of the spring allows the roller 25 to smoothly navigate corners even with slight differences in the front and rear wheel tracks.

[0097] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
