Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle parts, and in particular to a connection and sealing structure based on a motorcycle motor. Background Technology
[0002] In the electronic control system of modern motorcycles, the throttle control motor is responsible for regulating the airflow into the engine, thus directly affecting engine performance, fuel consumption, and emissions. To ensure the motor operates normally under various environmental conditions, the design of the sealing structure is particularly important. However, many current throttle control motors have certain defects in their sealing structures, resulting in poor sealing performance. Existing sealing structures often fail to effectively prevent the intrusion of moisture and other external factors, especially in humid or rainy environments. Moisture can easily penetrate into the motor from the connection points, potentially causing moisture corrosion of the internal electrical components and mechanical parts, leading to a series of problems.
[0003] First, moisture penetration can cause corrosion of internal motor components. Metal parts are prone to reacting with moisture in humid environments, forming a rust layer, which can lead to component failure in severe cases. Once corrosion occurs inside the motor, the mechanical and electrical properties of the components will be affected, thus impacting the normal operation of the entire throttle control system.
[0004] Secondly, the moisture that seeps in may also cause poor contact in the motor. After being corroded by moisture, the conductivity of the internal connection terminals and circuit boards of the motor may decrease, or even short circuits may occur. Poor contact will prevent the motor from accurately receiving control signals, thereby affecting the adjustment of the intake air volume, and thus affecting the performance and response speed of the engine. Utility Model Content
[0005] (I) Purpose of the utility model
[0006] In view of this, the purpose of this utility model is to propose a connection sealing structure based on a motorcycle motor. This device provides a sealing element between the plug end and the motorcycle terminal housing. The sealing element ensures the airtightness between the plug end and the motorcycle terminal housing, preventing moisture from seeping into the plug end from the connection point and causing corrosion of the internal components, resulting in poor contact and increasing the safety of the device.
[0007] (II) Technical Solution
[0008] To achieve the above technical objectives, this utility model provides a connection and sealing structure based on a motorcycle motor, which includes a motorcycle terminal housing and a motor body. The motorcycle terminal housing is mounted on the motorcycle, and a tail shell is provided at the rear of the motor body. A plug-in end is provided on one side of the tail shell. One end of the plug-in end is detachably inserted into the motorcycle terminal housing. A sealing element is embedded and installed circumferentially around the outer surface of the plug-in end. A sealing groove is opened at a corresponding position on the inner wall of the motorcycle terminal housing to accommodate the sealing element, so that when the plug-in end is inserted into the motorcycle terminal housing, the sealing element is engaged in the sealing groove, thereby sealing the connection position between the plug-in end and the motorcycle terminal housing.
[0009] As a further description of the above technical solution: the sealing element is elastic.
[0010] As a further description of the above technical solution: the sealing element includes a rigid mating base, a first protrusion and a second protrusion. The rigid mating base is embedded on the surface of the insertion end. The first protrusion and the second protrusion are respectively adhered to or integrally formed on the surface of the rigid mating base, and the first protrusion and the second protrusion completely cover the rigid mating base. This double-protruding sealing structure greatly improves the sealing effect of the sealing element.
[0011] As a further description of the above technical solution: the cross-sections of the first protrusion and the second protrusion both adopt a semi-circular structure. The cross-sectional diameter of the first protrusion is smaller than that of the second protrusion. The first protrusion is located on the side closer to the outer end of the plug-in terminal, and the second protrusion is located on the side farther from the outer end of the plug-in terminal. Therefore, during the process of inserting the plug-in terminal into the motorcycle terminal sleeve, it will first come into contact with the first protrusion and then gradually come into contact with and be squeezed to the second protrusion, which facilitates the insertion of the plug-in terminal.
[0012] As a further description of the above technical solution: the first protrusion and the second protrusion are respectively provided with a first air chamber and a second air chamber, which are interconnected. The plug end is provided with an air passage that can inflate the first air chamber and the second air chamber. Therefore, during the insertion of the plug end, the air passage can be opened to discharge the gas in the first air chamber and the second air chamber, thereby facilitating the insertion of the plug end. After the plug end is inserted into place, air is inflated into the first air chamber and the second air chamber through the air passage, so that the sealing element forms a sealing structure between the plug end and the motorcycle terminal sleeve.
[0013] As a further description of the above technical solution: the plug end is provided with side ridges on both sides, the motorcycle terminal sleeve is provided with side ridge mating sleeves that are adapted to the side ridges on both sides, the sealing element surrounds and covers the side ridges, the air passage is opened in the side ridges, one end of the air passage extends to the end of the side ridge near the tail shell and is fitted with a plug, and the other end of the air passage passes through the hard fitting bottom plate and communicates with the first air cavity in the first protrusion.
[0014] In the above technical solution, the present invention provides a connection sealing structure based on a motorcycle motor. This device controls the movement of the adjusting cap by the motor, changes the gap between the adjusting cap and the throttle valve seat, and realizes the control of the intake volume of the motorcycle throttle valve channel. The whole control is simple, and the intake control response is fast and efficient. In addition, the device adopts a split structure, that is, the adjusting cap and the inner sleeve for installing the adjusting cap are both detachable. Therefore, the adjusting cap and adjusting screw can be replaced periodically to ensure the stability and accuracy of the intake control.
[0015] The motor in this device is detachably inserted into the motorcycle terminal housing via a plug-in end and is fastened together by a fastening assembly. Therefore, when it is necessary to disassemble the entire device, it is only necessary to unlock the plug-in end from the motorcycle terminal housing by using the fastening assembly and then pull out the plug-in end. The operation is convenient and quick.
[0016] This device uses a seal between the plug-in terminal and the motorcycle terminal housing to ensure a tight seal between them. This prevents moisture from seeping into the plug-in terminal from the connection point, which could lead to corrosion of internal components and poor contact. This increases the device's safety. Furthermore, the seal's structural design enhances its sealing performance and minimizes its impact on plug-in terminal installation, making installation easier. Attached Figure Description

[0028] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.
[0029] Example 1
[0030] like Figures 1-5 As shown: This embodiment provides a technical solution: a connection sealing structure based on a motorcycle motor, including a motor body 1, an inner sleeve 6, and an adjusting cap 3. The inner sleeve 6 has a cylindrical structure and is detachably assembled at the front end of the motor body 1. The adjusting cap 3 is movably sleeved on the inner sleeve 6 and can move along the axial direction of the inner sleeve 6. A threaded adjusting rod 61 is rotatably installed at the center of the inner sleeve 6. The end of the threaded adjusting rod 61 is connected to the output shaft of the motor body 1. An inner limiting sleeve 32 is installed axially at the center of the adjusting cap 3. A threaded hole 320 is opened axially at the center of the inner limiting sleeve 32. The front end of the threaded adjusting rod 61 is screwed into the threaded hole 320, so that when the threaded adjusting rod 61 rotates, the adjusting cap 3 can move axially on the inner sleeve 6 to realize the control of the air intake volume of the motorcycle passage.
[0031] Working principle: This device is installed on the motorcycle throttle body and is used to control the air intake of the motorcycle throttle passage by changing the gap between the adjusting cap 3 and the throttle valve seat. In use, the motor body 1 is first installed on the motorcycle throttle body. After installation, the front end of the adjusting cap 3 extends into the motorcycle throttle valve seat. When the motor body 1 is running, the motor body 1 drives the threaded adjusting rod 61 to rotate. When the threaded adjusting rod rotates, its front end is screwed into the threaded hole 320, causing the adjusting cap 3 to move axially on the inner sleeve 6, thereby controlling the air intake of the motorcycle passage.
[0032] Specifically, such as Figures 2-5 As shown, in order to ensure that the adjusting rod 61 can drive the adjusting cap 3 to move axially when it rotates, in this embodiment, the inner sleeve 6 has an axial cavity 60. The cross-section of the cavity 60 is waist-shaped. The cross-sectional shape of the inner limiting sleeve 32 is adapted to the cross-sectional shape of the cavity 60, so that there is no relative rotation between the inner limiting sleeve 32 and the inner sleeve 6. Therefore, when the threaded adjusting rod rotates, the adjusting cap 3 moves axially on the inner sleeve 6 to realize the air intake control of the motorcycle passage.
[0033] Specifically, such as Figures 2-5As shown, in order to achieve accurate control of the air intake volume of the motorcycle passage, in this embodiment, the adjusting cap 3 includes an adjusting head 30 and a cylindrical part 31. The adjusting head 30 is disposed at the front end of the cylindrical part 31. The adjusting head 30 adopts a frustum-shaped structure with the diameter gradually increasing from top to bottom. The inner limiting sleeve 32 is disposed inside the cylindrical part 31. Based on this, when the adjusting head 30 moves, the adjusting head 30 at its front end can achieve accurate control of the air intake volume of the motorcycle passage.
[0034] Specifically, such as Figures 2-5 As shown, since the adjustment head 30 is used very frequently, the adjustment cap 3 needs to be replaced regularly. In order to facilitate the replacement of the adjustment cap 3, in this embodiment, a base plate 64 is installed at the bottom of the inner sleeve column 6. The base plate 64 is fixedly installed at the front end of the motor body 1 by connecting studs 10. Therefore, the entire adjustment cap 3 and the inner sleeve column 6 can be disassembled and replaced to ensure the stable movement of the adjustment cap 3 for long-term use, thereby ensuring accurate control of the air intake volume of the motorcycle channel.
[0035] Specifically, such as Figures 2-5 As shown, in order to facilitate the disassembly and replacement of the adjusting cap 3, in this embodiment, the threaded adjusting rod 61 and the output shaft of the motor body 1 are detachably assembled and connected. A coaxial plug 11 is welded and installed on the output shaft of the motor body 1. A coaxial insertion hole 610 is provided axially at the bottom of the threaded adjusting rod 61. When the threaded adjusting rod 61 is connected to the output shaft of the motor body 1, the coaxial plug 11 is inserted into the coaxial insertion hole 610. The coaxial plug 11 adopts a non-cylindrical structure so that when the coaxial plug 11 is inserted into the coaxial insertion hole 610, the threaded adjusting rod 61 can rotate synchronously with the output shaft of the motor body 1.
[0036] Specifically, such as Figures 2-5 As shown, in order to ensure a stable connection between the threaded adjusting rod 61 and the output shaft of the motor body 1, in this embodiment, a bearing 66 is fixedly connected to the lower part of the inner sleeve column 6 via a connecting rod 65. The bottom of the threaded adjusting rod 61 is inserted into the bearing 66, and the threaded adjusting rod 61 is rotatably installed in the inner sleeve column 6 via the bearing 66.
[0037] Specifically, such as Figures 2-5As shown, in order to separate the adjusting cap 3 from the inner sleeve post 6 after disassembly or to prevent accidental separation, in this embodiment, a retaining ring 62 is provided at the upper edge of the inner sleeve post 6. The retaining ring 62 has at least one opening 63. A baffle 33 is provided at the corresponding position of the opening 63 on the lower inner wall of the adjusting cap 3. The length of the baffle 33 is the same as the width of the opening 63. Telescopic spring rods 330 are provided at both ends of the baffle 33. Based on this, when the spring rod 330 is pressed and retracted into the baffle 33, the adjusting cap 3 can move upward to move the baffle 33 out of the opening 63, thereby separating the adjusting cap 3. When the spring rod 330 remains extended, the baffle 33 cannot move out of the opening 63, and the adjusting cap 3 cannot be separated from the inner sleeve post 6. This allows the device to meet different scenario requirements. That is, when it is necessary to separate the adjusting cap 3, the spring rod 330 can be pressed to separate the adjusting cap 3. When it is not necessary to separate the adjusting cap 3, the adjusting cap 3 will not fall off abnormally.
[0038] Example 2
[0039] like Figures 6-9 As shown: This embodiment provides a technical solution: a detachable motorcycle motor, wherein the motor body 1 is detachably connected to the motorcycle terminal housing 5, the tail of the motor body 1 is provided with a tail shell 2, and a plug-in end 4 is provided on one side of the tail shell 2. One end of the plug-in end 4 is detachably inserted into the motorcycle terminal housing 5 and is fastened and connected by a fastening component 42.
[0040] Specifically, such as Figures 6-9 As shown, in order to achieve the fastening connection of the fastening assembly 42, in this embodiment, the fastening assembly 42 includes a wedge-shaped buckle 420 movably mounted on the surface of the plug-in end 4 and a locking slot 52 formed on the surface of the motorcycle terminal housing 5. The wedge-shaped buckle 420 can be moved into the plug-in end 4 by pressing. When the plug-in end 4 is inserted into the motorcycle terminal housing 5, the wedge-shaped buckle 420 is engaged in the locking slot 52. This structural arrangement ensures that when the wedge-shaped buckle 420 is engaged in the locking slot 52, the plug-in end 4 is fixedly connected to the motorcycle terminal housing 5. When the wedge-shaped buckle 420 is moved out of the locking slot 52, the plug-in end 4 can be pulled out from one end of the motorcycle terminal housing 5, thereby realizing the locking and unlocking of the plug-in end 4.
[0041] Specifically, such as Figures 6-9As shown, in order to install the wedge-shaped buckle 420, in this embodiment, an installation cavity 43 is provided on the surface of the plug end 4 at the position where the wedge-shaped buckle 420 is installed. The wedge-shaped buckle 420 is movably assembled in the installation cavity 43, so that the wedge-shaped buckle 420 can be pressed into the installation cavity 43. Based on this, when the wedge-shaped buckle 420 is pressed and can be retracted into the installation cavity 43, the plug end 4 can be pulled out from one end of the motorcycle terminal sleeve 5. Conversely, the plug end 4 is locked in the motorcycle terminal sleeve 5.
[0042] Specifically, such as Figures 6-9 As shown, in order to ensure that the wedge-shaped buckle 420 can automatically pop out and engage in the locking slot 52 when it is not pressed, thereby locking the insertion end 4, in this embodiment, two elastic components 421 are symmetrically installed between the bottom of the wedge-shaped buckle 420 and the interior of the mounting cavity 43. The elastic components 421 can provide an outward elastic force to the wedge-shaped buckle 420, so that when the wedge-shaped buckle 420 is not under pressure, it can automatically pop out and engage in the locking slot 52, thereby locking the insertion end 4. Specifically, the elastic component 421 is a spring or a sheet.
[0043] Furthermore, such as Figure 9 As shown, in order to prevent the wedge-shaped buckle 420 from coming out of the mounting cavity 43, anti-detachment plates 422 are provided on both sides of the bottom of the wedge-shaped buckle 420. The inner wall of the mounting cavity 43 is provided with a limiting groove (not shown in the figure) that can restrict the movement of the anti-detachment plates 422, so that the movement of the wedge-shaped buckle 420 is always limited to the range of the limiting groove.
[0044] Specifically, such as Figures 6-9 As shown, in order to prevent moisture from seeping into the plug end 4 from the locking slot 52 and causing corrosion of the internal components of the plug end 4, resulting in poor contact, in this embodiment, a sealing sleeve 51 is provided on the surface of the motorcycle terminal sleeve 5 at the locking slot 52. The sealing sleeve 51 is made of elastic rubber and covers the locking slot 52. Based on this, the sealing sleeve 51 will not block the wedge-shaped buckle 420 pressed and engaged in the locking slot 52, and can also ensure the sealing of the locking slot 52 after the plug end 4 is installed.
[0045] Example 3
[0046] like Figures 6-9As shown: This embodiment provides a technical solution: a connection sealing structure based on a motorcycle motor. In order to improve the sealing performance between the plug-in end 4 and the motorcycle terminal sleeve 5, and to prevent moisture from penetrating into the interior of the plug-in end 4 from the connection position between the plug-in end 4 and the motorcycle terminal sleeve 5, which could lead to corrosion of the internal components of the plug-in end 4 and poor contact, in this embodiment, a sealing element 40 is circumferentially embedded and installed on the outer surface of the plug-in end 4. A sealing groove that can accommodate the sealing element 40 is opened at the corresponding position on the inner wall of the motorcycle terminal sleeve 5. When the plug-in end 4 is inserted into the motorcycle terminal sleeve 5, the sealing element 40 is engaged in the sealing groove, thereby achieving a seal at the connection position between the plug-in end 4 and the motorcycle terminal sleeve 5.
[0047] Specifically, such as Figures 6-8 As shown, in order to ensure that the plug-in end 4 can be smoothly inserted into the motorcycle terminal sleeve 5, in this embodiment, the seal 40 is made of elastic material.
[0048] Specifically, such as Figures 6-8 As shown, in order to improve the sealing effect of the seal 40, in this embodiment, the seal 40 includes a rigid mating base plate 404, a first protrusion 400 and a second protrusion 401. The rigid mating base plate 404 is embedded on the surface of the insertion end 4. The first protrusion 400 and the second protrusion 401 are respectively adhered to or integrally formed on the surface of the rigid mating base plate 404, and the first protrusion 400 and the second protrusion 401 completely cover the rigid mating base plate 404. This double-protruding sealing structure greatly improves the sealing effect of the seal 40.
[0049] Specifically, such as Figures 6-9 As shown, in order to facilitate the insertion of the plug end 4 into the motorcycle terminal sleeve 5, in this embodiment, the cross-sections of the first protrusion 400 and the second protrusion 401 are both semi-circular. The cross-sectional diameter of the first protrusion 400 is smaller than that of the second protrusion 401. The first protrusion 400 is located on the side closer to the outer end of the plug end 4, and the second protrusion 401 is located on the side farther from the outer end of the plug end 4. Therefore, during the process of inserting the plug end 4 into the motorcycle terminal sleeve 5, it will first come into contact with the first protrusion 400, and then gradually come into contact with and be squeezed to the second protrusion 401. This facilitates the insertion of the plug end 4.
[0050] Specifically, such as Figures 6-9As shown, in order to reduce the obstruction of the sealing member 40 during the insertion of the plug-in terminal 4 into the motorcycle terminal sleeve 5, thereby facilitating the insertion of the plug-in terminal 4, in this embodiment, the first protrusion 400 and the second protrusion 401 are respectively provided with a first air chamber 402 and a second air chamber 403. The first air chamber 402 and the second air chamber 403 are interconnected, and the plug-in terminal 4 is provided with an air passage 411 that can inflate the first air chamber 402 and the second air chamber 403. Therefore, during the insertion of the plug-in terminal 4, the air passage 411 can be opened to discharge the gas in the first air chamber 402 and the second air chamber 403, thereby facilitating the insertion of the plug-in terminal 4. After the plug-in terminal 4 is inserted in place, the first air chamber 402 and the second air chamber 403 are inflated through the air passage 411, so that the sealing member 40 forms a sealing structure between the plug-in terminal 4 and the motorcycle terminal sleeve 5.
[0051] Specifically, such as Figures 6-9 As shown, in order to facilitate the inflation of the first air chamber 402 and the second air chamber 403 through the air passage 411, in this embodiment, side ridges 41 are provided on both sides of the plug end 4, and side ridge mating sleeves 50 adapted to the side ridges 41 are provided on both sides of the motorcycle terminal sleeve 5. The sealing member 40 surrounds and covers the side ridges 41, and the air passage 411 is opened in the side ridge 41. One end of the air passage 411 extends to the end of the side ridge 41 near the tail shell 2 and is fitted with a plug 410. The other end of the air passage 411 passes through the hard fitting bottom plate 404 and the first protrusion 400. The first air chamber 402 is connected, so when it is necessary to inflate the first air chamber 402 and the second air chamber 403, the plug 410 can be removed directly, and air can be inflated into the first air chamber 402 and the second air chamber 403 through the air passage 411. The operation is convenient and the inflation is unobstructed. In addition, it should be noted that in order to ensure the sealing effect, a pressure sensor can also be installed in the air passage 411. The pressure sensor can sense the air pressure in the air passage 411, the first air chamber 402 and the second air chamber 403, so as to understand the sealing effect of the sealing element 40.
[0052] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
