Description

Technical Field

[0001] The utility model belongs to the field of motorcycle shock absorbers, and particularly relates to a motorcycle air suspension shock absorber and a motorcycle shock control system. Background Art

[0002] A motorcycle shock absorber is a device installed between a motorcycle frame and a swing arm, which has the function of suppressing resonance, reducing the bumps and vibrations of the motorcycle during driving, and improving the comfort of the passengers and the handling performance of the motorcycle.

[0003] Currently, there are various types of shock absorbers used on motorcycles, such as hydraulic shock absorbers, spring shock absorbers or air suspension shock absorbers. The air suspension shock absorbers in the prior art often adopt airbag type. For example, the technical solutions disclosed in the patents with publication numbers CN213541155U (adopting an external airbag arranged outside the damper) or CN219529683U (adopting an airbag layout coaxial with the damper).

[0004] However, the airbag type air suspension shock absorbers used on motorcycles still have certain deficiencies, specifically: the product has a large volume (it is difficult to achieve a compact design), and the airbag is easily damaged, resulting in a reduction or failure of the air shock absorption effect.

[0005] Based on this, the applicant considers designing a motorcycle air suspension shock absorber and a motorcycle shock control system with a more compact structure, higher reliability and better versatility. Summary of the Invention

[0006] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is:

[0007] How to provide a motorcycle air suspension shock absorber, a motorcycle shock control system and a control method with a more compact structure, higher reliability and better versatility.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A motorcycle air suspension shock absorber, including a damper, the damper having a damper housing and a damper telescopic rod; further including a regulation air chamber, characterized in that:

[0010] The regulation air chamber includes a cylindrical shell coaxially arranged with the damper, one axial end of the cylindrical shell being a sliding socket end and the other end being a sealed mounting end;

[0011] There is a sliding seal socket between the sliding socket end and the outer side wall of the damper housing;

[0012] A end cover is fixedly arranged at the sealed installation end, and the end cover is fixedly connected in a sealed manner with the outer end of the damping telescopic rod;

[0013] An airtight air cavity is formed inside the cylindrical shell, and an air charging and discharging interface that is hermetically connected to the airtight air cavity is also arranged on the cylindrical shell.

[0014] Compared with the prior art, the advantages of the motorcycle air suspension shock absorber in this technical solution are:

[0015] 1. The structure can be more compact, the reliability is higher, and the versatility is better

[0016] In the motorcycle air suspension shock absorber of this solution, the built-in or external air storage airbag is cancelled, and the above-mentioned cylindrical shell and the damper are used together to form an airtight air cavity inside the cylindrical shell for air charging and discharging, and it is easy to realize that the shock absorber quickly adjusts the elastic force and its own length of the air spring to reduce vibration.

[0017] Based on this, the shock absorber of this solution can not only effectively control the overall volume of the shock absorber, but especially can greatly reduce the outward convex size of the shock absorber in the radial direction, making the overall structure of the shock absorber more compact and improving the applicability of installation and use on motorcycles of different sizes, and effectively reducing the wind resistance.

[0018] At the same time, it can also make the overall shape of the shock absorber appear more concise and beautiful.

[0019] In addition, because the cylindrical shell is made of hard material, it can effectively prevent the shock absorption failure caused by the puncture of the airbag; improve the reliability of long-term use.

[0020] 2. It has better anti-pinch and use safety

[0021] The external part of the motorcycle air suspension shock absorber of this solution is not equipped with a shock absorption spring, so it can effectively avoid the shock absorption spring from compressing and clamping the body of the driver and passenger or the carried object due to large vibrations, so as to play a better anti-pinch role and improve the safety of long-term use.

[0022] A motorcycle shock absorption control system, characterized in that: it includes a motorcycle air suspension shock absorber; it also includes an electric control air pump, an electric control valve air charging and discharging distribution valve, a control module and a parameter detection sensor;

[0023] The motorcycle air suspension shock absorber is used for being installed in pairs between the frame and the swing arm of the motorcycle;

[0024] The output port of the electronically controlled air pump is hermetically connected to the input port on the electronically controlled valve air charging and discharging distribution valve through an air pipe; the electronically controlled valve air charging and discharging distribution valve has an air discharging port and at least one air charging port. Among them, the air charging port is hermetically connected to the air charging and discharging interface on the motorcycle air suspension shock absorber through an air pipe and forms an air charging and discharging loop;

[0025] The electronically controlled air pump and the electronically controlled valve air charging and discharging distribution valve are electrically controlled and connected to the corresponding interfaces on the control module through cables respectively;

[0026] The parameter detection sensor is electrically connected to the input interface on the control module through a cable; the parameter detection sensor includes a pressure sensor and a height sensor. The detection end of the pressure sensor is used to detect the air pressure in the pipeline of the air charging and discharging loop; the height sensor is fixedly installed on the motorcycle and is used to detect the body height;

[0027] The control module can also obtain the real-time driving speed parameter of the motorcycle. Description of the Drawings

[0041] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0042] The motorcycle air suspension shock absorber comprises a damper, wherein the damper has a damper housing and a damping telescopic rod; and further comprises a regulating air chamber,

[0043] The regulating air chamber comprises a cylindrical shell coaxially arranged with the damper, one axial end of the cylindrical shell is a sliding sleeve end, and the other end is a sealing installation end;

[0044] The sliding sleeve connection end and the outer side wall of the damper housing are connected in a sliding sealing sleeve connection;

[0045] The sealing installation end is fixedly provided with an end cover, and the end cover is sealed and fixedly connected to the outer end of the damping telescopic rod;

[0046] A sealed air cavity is formed inside the cylindrical shell, and a gas charging and discharging interface sealedly connected to the sealed air cavity is also provided on the cylindrical shell.

[0047] During implementation, the end of the damper housing away from the damping telescopic rod and the outer end surface of the end cover are both provided with an assembly connection structure, and the assembly connection structure can adopt a connecting lug (for fitting), a threaded rod (for threaded connection) or a welding end (for fixed connection).

[0048] During implementation, the damper is an air damper or a hydraulic damper.

[0049] During implementation, the cylindrical shell of the regulating air chamber is made of hard anti-corrosion metal (such as stainless steel or aluminum alloy).

[0050] Wherein, the gas charging and discharging interface is located on the outer end surface of the end cover.

[0051] In this way, the air charging and discharging interface can be made closer to the upper end position of the entire shock absorber along the axial direction, which is closer to the upper side of the motorcycle frame. This can shorten the distance between the air charging and discharging interface and the air charging and discharging control valve, shorten the length of the air pipeline, and improve the reliability of the entire air pipeline.

[0052] During implementation, an implementation manner of the sliding sealing sleeve structure between the above-mentioned regulating air chamber and the damper is as follows:

[0053] A structure can be adopted in which an annular sealing groove is provided on the contact surface between the sliding sleeve end of the cylindrical shell and the outer side wall of the damper housing, and an O-ring is filled in the annular sealing groove.

[0054] Preferably, the sliding sealing sleeve between the regulating air chamber and the damper adopts the following structure:

[0055] Wherein, a ring of inwardly convex limiting steps is provided at a position inside the cylindrical shell close to the sliding sleeve end, and a bushing is coaxially and fixedly connected to the radially inner end surface of the limiting step, and a sliding fit connection is formed between the bushing and the outer side wall of the damper housing;

[0056] An annular space is formed inside the cylindrical shell along its own axial direction from the limiting step to between the sliding sleeve end and the damper housing. An annular washer, an annular sealing packing, and a locking retaining ring for tightly locking the annular sealing packing are sequentially arranged along the axial direction in the annular space starting from the limiting step.

[0057] The setting of the above-mentioned bushing can form surface contact, avoid local accelerated wear caused by stress concentration, effectively reduce the friction of the sliding contact between the cylindrical shell and the damper housing, better ensure the smoothness of the sliding fit connection between the two for a long time, and better ensure the reliability of the shock absorber for a long time.

[0058] The above-mentioned annular packing seal is used to seal the gap between the sliding contact surfaces between the sliding sleeve end of the cylindrical shell of the regulating air chamber and the outer side wall of the damper housing.

[0059] The above-mentioned sliding sealing sleeve structure is relatively simple and easy to assemble.

[0060] During implementation, the bushing can be made of smooth and wear-resistant metal (such as bearing alloy or stainless steel) or non-metal (such as nylon or polypropylene).

[0061] During implementation, a sliding seal lubrication structure is further provided between the sliding sleeve end of the cylindrical shell of the regulating air chamber and the outer side wall of the damper housing. The sliding seal lubrication structure includes a sealing ring

[0062] During implementation, the annular washer can be an elastic metal sheet with a fracture opening in the circumferential direction. Correspondingly, an annular assembly groove is provided on the inner side of the cylindrical housing, into which the radially outer end of the elastic expandable annular washer can be snapped. In this way, the annular washer for locking can be sleeved after compression and finally expand and lock in the annular assembly groove under its own elastic force, and at the same time, the annular sealing packing can be tightly pressed and locked by its own end face.

[0063] Among them, the upper section in the axial direction of the end cover is a cylindrical structure, and the lower section in the axial direction is a cylindrical structure;

[0064] The outer side of the cylindrical structure of the end cover is provided with an external thread, and the lower end is an open end; it is fixedly connected through the external thread and the internal thread of the cylindrical housing of the control air chamber;

[0065] An annular sealing groove with an O-ring sleeved is provided on the outer side of the cylindrical structure of the end cover adjacent to the external thread;

[0066] The end face of the cylindrical structure of the end cover above the annular sealing groove protrudes radially outward to form a limiting convex ring, which is used to abut and connect with the end face of the cylindrical housing of the control air chamber, and the outer diameter of the limiting convex ring is less than or equal to the outer diameter of the end face of the cylindrical housing of the control air chamber.

[0067] The above-mentioned end cover has high self-structural strength, and the lower section is a cylindrical structure, which can form a larger threaded connection surface on the outside to improve the reliability of the threaded connection;

[0068] At the same time, the volume of the sealed air chamber can also be increased through the internal space of the cylindrical structure, the pressure regulation range of the control air chamber can be improved, and the personalized requirements of different working conditions and users for shock absorption performance can be better met.

[0069] During implementation, a shock pad is also sleeved on the length section of the damping telescopic rod in the sealed air chamber, and the shock pad is made of rubber or silica gel material.

[0070] Among them, a through hole for the damping telescopic rod to penetrate through hermetically is provided at the center of the cylindrical structure of the end cover, and an annular sealing groove with an O-ring sleeved is provided on the inner wall of the through hole;

[0071] The outer end of the damping telescopic rod is a threaded connection section with an external thread; an installation hole communicating with the through hole is provided on the outer end face of the cylindrical structure of the cover, and the threaded connection section of the damping telescopic rod is located in the installation hole and is fixedly connected by threads with a limit nut and an upper joint with a threaded hole at the bottom.

[0072] The end cap adopting the above structure can not only play a role in reliably sealing the end face, but also make full use of its own structure to form a simple and convenient assembly and fixation between the damping telescopic rod and the upper joint, thereby helping to improve the assembly efficiency between the entire shock absorber and the upper joint.

[0073] Wherein, an enhanced protective sleeve is fixedly sleeved on the outer side surface of the damper housing, and a sliding sealing sleeve connection is formed between the outer side surface of the enhanced protective sleeve and the sliding sleeve end of the cylindrical housing of the regulating air chamber.

[0074] After adopting the above enhanced protective sleeve, the structural strength and wear resistance of the damper housing can be enhanced through the enhanced protective sleeve, and a lasting and reliable sliding fit connection with the cylindrical housing of the regulating air chamber can be better ensured, thereby lasting ensuring the reliability of the shock absorber of this solution for long-term use.

[0075] Wherein, the enhanced protective sleeve includes a fixed sleeve and a detachable sleeve with an overall cylindrical structure;

[0076] The fixed sleeve is fixedly sleeved at a position on the damper housing far from the damping telescopic rod in the length direction; on the fixed sleeve, there are successively arranged from bottom to top a limiting end with a circumferential limiting protrusion protruding radially outward, a sealing section with a sealing groove internally sleeved with an O-ring, and a threaded section for threaded connection;

[0077] The lower section of the detachable sleeve has an internal thread for threaded connection with the threaded section. The detachable sleeve is fixedly connected to the threaded section through the internal thread, and the lower section of the detachable sleeve is located below the internal thread and is sleeved and connected with the sealing section, and the lower end abuts against the upper end surface of the limiting protrusion;

[0078] The upper section of the detachable sleeve is sleeved with the damper housing, and a sliding sealing sleeve connection is formed between the outer side surface of the upper section of the detachable sleeve and the sliding sleeve end of the cylindrical housing of the regulating air chamber.

[0079] The advantages of the above enhanced protective sleeve including the fixed sleeve and the detachable sleeve are as follows:

[0080] 1. The two are component structures, more suitable for separate production, and the assembly is also relatively simple, which can help improve the assembly efficiency.

[0081] 2. The detachable sleeve has a sliding fit connection with the regulating air chamber. Once the detachable sleeve is worn, it is easy to disassemble and replace separately; in this way, the cost of replacement and maintenance for long-term use of this product can be reduced.

[0082] During implementation, both the fixed sleeve and the limiting sleeve are made of metal hard materials (such as: stainless steel or aluminum alloy).

[0083] During implementation, the fixed sleeve can be welded or integrally formed with the damper housing.

[0084] During implementation, the motorcycle air suspension shock absorber further includes a dust cover. Annular clamping grooves are provided on the outer side of the lower section of the detachable sleeve and on the outer side of the sliding socket end of the cylindrical housing of the regulating air chamber. Protrusions for clamping in the annular clamping grooves are provided on the inner sides of the two open ends of the dust cover. The dust cover is then assembled by sleeving a clamping hoop on the outer side of the dust cover at the location corresponding to the protrusion.

[0085] The above dust cover can shield the regulating air chamber and the structural section where it is slidably and sealingly sleeved, better avoiding the situation where dust adheres to this place and causes accelerated wear. It can be seen that the above dust cover can play a better protective role and extend the service life of the product.

[0086] The motorcycle shock control system includes the above-mentioned motorcycle air suspension shock absorber; it also includes an electric control air pump, an electric control valve air charging and discharging distribution valve, a control module, and a parameter detection sensor;

[0087] The motorcycle air suspension shock absorber is used to be installed in pairs between the motorcycle frame and the swing arm.

[0088] The output port of the electric control air pump is hermetically connected to the input port on the electric control valve air charging and discharging distribution valve through an air delivery pipe; the electric control valve air charging and discharging distribution valve has one air discharging port and at least one air charging port. Among them, the air charging port is hermetically connected to the air charging and discharging interface on the motorcycle air suspension shock absorber through an air delivery pipe to form an air charging and discharging loop;

[0089] The electric control air pump and the electric control valve air charging and discharging distribution valve are each electrically controlled and connected to the corresponding interfaces on the control module through cables;

[0090] The parameter detection sensor is electrically connected to the input interface on the control module through a cable; the parameter detection sensor includes a pressure sensor and a height sensor. The detection end of the pressure sensor is used to detect the air pressure in the pipeline of the air charging and discharging loop; the height sensor is fixedly installed on the motorcycle and is used to detect the vehicle body height;

[0091] The control module can also obtain the real-time driving speed parameter of the motorcycle.

[0092] During implementation, the control module can adopt an independent ECU, an independent single-chip microcomputer, or the ECU of the motorcycle. Preferably, the control module adopts an independent ECU, and this ECU is electrically connected to the ECU of the motorcycle through a cable to obtain the driving speed parameter of the motorcycle.

[0093] During implementation, it is preferred that the electronically controlled valve charging and discharging distribution valve has two charging ports, and each charging port is hermetically connected to the charging and discharging interface of a corresponding motorcycle air suspension shock absorber through a pipeline, forming two independent charging and discharging circuits.

[0094] A sealed air chamber expansion component is also provided in the charging and discharging circuit. The sealed air chamber expansion component includes an expansion gas cylinder and a three-way joint. The expansion gas cylinder has a sealed chamber inside and a charging and discharging port on the cylinder body that is connected to the sealed chamber. The charging and discharging port is hermetically connected to one of the interfaces of the three-way joint, and the other two interfaces of the three-way joint are hermetically connected to the pipeline of the charging and discharging circuit.

[0095] After adopting the above-mentioned sealed air chamber expansion component, the volume of the sealed air chamber can be increased through the sealed chamber of the expansion gas cylinder, further expanding the pressure regulation range of the control air chamber, and better meeting the personalized requirements of different working conditions and users for shock absorption performance.

[0096] The control method of the motorcycle shock absorption control system includes the following steps:

[0097] step1. Set preset values:

[0098] The body height of the motorcycle in the low position mode is preset as Hl in the control module, the body height of the motorcycle in the high position mode is preset as Hh in the control module, Hl is less than Hh; the preset regulation speed value Vd is set in the control module.

[0099] step2. Obtain real-time values:

[0100] The real-time driving speed of the motorcycle is Vr, the real-time detection value of the height sensor is Hr, and the real-time detection value of the pressure sensor is Pr.

[0101] step3. Logical judgment and control:

[0102] When Vr is less than or equal to Vd: The control module regulates the electronically controlled air pump and the electronically controlled valve charging and discharging distribution valve to achieve charging and discharging until Hr is approximately equal to Hl.

[0103] When Vr is greater than Vd: The control module regulates the electronically controlled air pump and the electronically controlled valve charging and discharging distribution valve to achieve charging and discharging until Hr is approximately equal to Hh.

[0104] During implementation, it is preferred that Vd is 10 - 30 kilometers per hour (the default preferred setting is 15 kilometers per hour), and this value can be customized according to different users.

[0105] The above low mode and high mode can better meet the driving needs of motorcycle riders at low and high speeds and optimize the riding experience. For example, in the low mode at low speeds, the vehicle body is in a low-slung state, which is more suitable for people to touch the ground with their feet for temporary parking; when in the high mode, the vehicle body rises and has better passability, flexibly optimizing the driving experience of the motorcycle.

[0106] During specific implementation, the control module is signal-connected to the ECU of the motorcycle through the CAN bus; after the control module is powered on, the main control reads the vehicle speed signal of the motorcycle in real time through the CAN network and obtains the real-time driving speed of the motorcycle as Vr.

[0107] When the real-time driving speed Vr is lower than the preset regulation speed value Vd, if the vehicle body height is not within the expected height range (low mode), the control module regulates the electronic control air pump and the electronic control valve air charging and discharging distribution valve to achieve air charging and discharging, so as to achieve the purpose of adjusting the vehicle body height and shock absorption.

[0108] When the real-time driving speed Vr is greater than the preset regulation speed value Vd, if the vehicle body height is not within the expected height range (high mode), the control module regulates the electronic control air pump and the electronic control valve air charging and discharging distribution valve to achieve air charging and discharging, so as to achieve the purpose of adjusting the vehicle body height and shock absorption.

[0109] During the entire driving process of the motorcycle, the main control module will continuously read the real-time detection value Hr of the height sensor for real-time regulation. When the vehicle body height reaches the preset height, the exhaust or inflation action will be stopped immediately.

[0110] During implementation, the heights of the low mode and the high mode respectively can be set for Hl and Hh in the control module according to the actual situation. The control module can be communicatively connected to the mobile phone via Bluetooth and use the software pre-installed on the mobile phone to set the preset values and detect and obtain the real-time values, thereby facilitating personalized settings.

[0111] It can be seen that this technical solution can more flexibly meet the shock absorption needs and riding habits of different users (for example, riders with a taller height can set Hl and Hh relatively higher; users with a shorter height or a heavier weight can set Hl and Hh relatively lower).

[0112] The above is only the preferred implementation mode of the present utility model. It should be noted that for those skilled in the art, without departing from the premise of this technical solution, several deformed and improved technical solutions should also be regarded as falling within the scope protected by this claim book.
