Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle motors, in particular to a motorcycle motor tail housing structure. Background Art

[0002] The well-known stepper motor rotates by the interaction between the magnetic rotor core and the pulse electromagnetic field generated by the stator. The screw stepper motor converts the rotational motion into linear motion inside the motor. The airflow control is achieved by setting an adjustment head at the end of the stepper motor output shaft. The motorcycle motor tail shell structure is a stepper motor mounting shell structure used for controlling airflow control on a motorcycle.

[0003] Existing motorcycle motor tail housing structures all have electrical plug interfaces to achieve electrical control connection, but the internal seal of the electrical plug interface is mostly sealed with a rubber ring. When the motorcycle is running, it is easy to cause the joint to vibrate, causing the rubber sealing ring to deform or be damaged by friction, and often lose the sealing effect, so that the external gas containing water vapor or other impurities enters the interior of the electrical plug interface and eventually affects the stability of the connection. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that the internal seal of an electrical plug interface is mostly sealed by a rubber ring, which easily causes the joint to vibrate when a motorcycle is running, causing the rubber sealing ring to deform or be damaged by friction and often lose its sealing effect. A motorcycle motor tail shell structure is provided, in which an annular air bag ring is arranged in the inner cavity of the electrical plug interface to cooperate with an air supply regulating mechanism to control the air supply of the annular air bag ring, thereby reducing the influence of the electrical plug interface moving backward during vibration on the extrusion deformation and friction of the annular air bag ring, and improving the sealing effect when the electrical plug interface is plugged in.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model discloses a motorcycle motor tail shell structure, comprising a motor tail shell body, a stepper motor assembly is installed in the motor tail shell body, and the output shaft end of the stepper motor assembly is fixedly connected with an adjusting head, the motor assembly comprises a stator fixed in the motor tail shell body, a rotor is rotatably arranged inside the stator, and an output shaft is spirally connected in the rotor, the adjusting head is fixedly connected with the end of the output shaft, the output shaft is axially rotated and locked, and when the rotor rotates, the output shaft is driven to move linearly, and finally the adjusting head is driven to move synchronously by the linear movement of the output head to achieve airflow control, and an electrical plug interface is integrally formed at the bottom of the motor tail shell body, and an annular airbag ring is arranged in the inner cavity of the electrical plug interface;

[0007] The bottom of the inner cavity of the electrical plug port is also provided with an air supply regulating mechanism, which is connected to the annular airbag ring. When the electrical plug port is plugged in, the air supply regulating mechanism passively drives the annular airbag ring to expand so as to seal during plugging.

[0008] Preferably, an annular notch is provided in the inner cavity of the electrical plug port, and the annular airbag ring is embedded and installed in the annular notch.

[0009] Preferably, the air supply regulating mechanism comprises a piston cylinder arranged at the top of the inner cavity of the electrical plug port, the piston cylinder is connected to the annular airbag ring through a connecting pipe, and a piston rod is embedded in the piston cylinder.

[0010] Preferably, a support spring is provided between the piston rod and the end of the piston cylinder, and the elastic force of the support spring is used to drive the piston rod to move away from the piston cylinder. When the electrical plug interface is plugged in, it will squeeze and drive the piston rod to move inside the piston cylinder. At this time, the piston rod injects the gas in the piston cylinder into the annular airbag ring through the connecting pipe, so that the annular airbag ring expands and protrudes to the outside of the annular notch to achieve sealing when the electrical plug interface is plugged in. At the same time, when vibration occurs and causes the electrical plug interface to move backward, at this time, under the action of the elastic force of the support spring, the piston rod moves away from the piston cylinder, and the gas in the annular airbag ring is returned to the piston cylinder, causing the annular airbag ring to shrink and deform, reducing the impact of the backward movement of the electrical plug interface on the extrusion deformation and friction of the annular airbag ring during vibration, and significantly providing a sealing effect when the electrical plug interface is plugged in.

[0011] Preferably, mounting protrusions are formed on both sides of the motor tail housing body, and mounting screw holes are provided on the mounting protrusions, and the mounting protrusions are used to install the motor tail housing body.

[0012] Preferably, a locking lug structure is provided on the outside of the electrical plug interface for locking the electrical plug interface when it is plugged in.

[0013] Preferably, the locking lug structure includes a docking seat integrally formed on the outside of the electrical plug interface, a snap-on portion is slidably sleeved on the docking seat, an adjusting screw is spirally penetrated and connected on the docking seat, and the bottom end of the adjusting screw is rotatably connected to the docking seat. Since the electrical plug interface vibrates when the motorcycle is running, it will cause extrusion and friction between the locking lug structure and the snap-on hole, causing deformation of the locking lug structure, thereby affecting the stability of the electrical plug interface connection, causing the vibration to intensify and causing poor contact. By setting the locking lug structure to be connected in a combined manner by the docking seat and the snap-on portion through the adjusting screw, the snap-on portion can be driven to protrude by the adjusting screw, thereby improving the stability of the electrical plug interface connected through the snap-on portion and preventing poor contact.

[0014] Compared with the prior art, the utility model has the following beneficial effects: by arranging an annular airbag ring and an air supply regulating mechanism in the inner cavity of the electrical plug interface, when the electrical plug interface is plugged in, the air supply regulating mechanism passively drives the annular airbag ring to expand for plugging and sealing, and when the electrical plug interface vibrates and moves backward when the motorcycle is running, the air supply regulating mechanism synchronously drives the annular airbag ring to contract to reduce the extrusion deformation and friction effects of the annular airbag ring during vibration, thereby improving the sealing effect when the electrical plug interface is plugged in.

[0015] Secondly, the present application arranges the locking lug structure to be connected in combination by a docking seat and a snap-fitting part through an adjusting screw. When the locking lug structure is deformed due to vibration of the electrical plug interface generated when the motorcycle is running for a long time, the snap-fitting part can be driven to protrude through the adjusting screw, thereby improving the stability of the electrical plug interface connected through the snap-fitting part and preventing poor contact.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4, further illustrating the specific implementation of the utility model of a motorcycle motor tail housing structure, to overcome the prior art that the internal sealing of the electrical plug interface is mostly sealed with a rubber ring, which is easy to cause vibration at the joint when the motorcycle is running, resulting in deformation or friction damage of the rubber sealing ring, which often loses the sealing effect, and provides a motorcycle motor tail housing structure, by arranging an annular airbag ring in the inner cavity of the electrical plug interface to cooperate with the air supply adjustment mechanism to adjust the air supply of the annular airbag ring, reduce the impact of the electrical plug interface backward movement on the annular airbag ring during vibration, and improve the sealing effect when the electrical plug interface is plugged in. The utility model of a motorcycle motor tail housing structure is not limited to the description of the following embodiments.

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, a motorcycle motor tail housing structure includes a motor tail housing body 1, a stepper motor assembly 2 is installed in the motor tail housing body 1, and the output shaft end of the stepper motor assembly 2 is fixedly connected with an adjusting head 3. Specifically, the motor assembly includes a stator fixed in the motor tail housing body 1, a rotor is rotatably arranged inside the stator, and an output shaft is spirally connected in the rotor, and the adjusting head 3 is fixedly connected to the end of the output shaft, and the output shaft is locked in axial rotation. When the rotor rotates, the output shaft is driven to move linearly, and finally the adjusting head 3 is driven to move synchronously by the linear movement of the output head to achieve airflow control;

[0024] An electrical plug port 12 is integrally formed at the bottom of the motor tail housing body 1. The electrical plug port 12 is used to make an electrical connection with an external connector. An inner cavity of the electrical plug port 12 is provided with an annular airbag ring 13. An air supply regulating mechanism 14 is also provided at the bottom of the inner cavity of the electrical plug port 12. The air supply regulating mechanism 14 is connected to the annular airbag ring 13. When the electrical plug port 12 is plugged in, the air supply regulating mechanism 14 passively drives the annular airbag ring 13 to expand for plug-in sealing.

[0025] The inner cavity of the electrical plug port 12 is provided with an annular notch, and the annular airbag ring 13 is embedded and installed in the annular notch. The air supply adjustment mechanism 14 includes a piston cylinder 142 arranged at the top of the inner cavity of the electrical plug port 12, and the piston cylinder 142 is connected with the annular airbag ring 13 through a connecting pipe 141, and a piston rod 143 is embedded in the piston cylinder 142. A support spring 144 is provided between the piston rod 143 and the end of the piston cylinder 142, and the elastic force of the support spring 144 is used to drive the piston rod 143 to move away from the piston cylinder 142. The two sides of the motor tail housing body 1 are formed with mounting protrusions 11, and the mounting protrusions 11 are provided with mounting screw holes.

[0026] Specifically, when the electrical plug interface 12 is plugged in, it will squeeze and drive the piston rod 143 to move into the piston cylinder 142. At this time, the piston rod 143 injects the gas in the piston cylinder 142 into the annular airbag ring 13 through the connecting tube 141, so that the annular airbag ring 13 expands and protrudes to the outside of the annular groove to achieve sealing when the electrical plug interface 12 is plugged in. At the same time, when vibration occurs and causes the electrical plug interface 12 to move backward, at this time, under the action of the elastic force of the support spring 144, the piston rod 143 moves away from the piston cylinder 142. At this time, the gas in the annular airbag ring 13 is returned to the piston cylinder 142, causing the annular airbag ring 13 to shrink and deform, thereby reducing the squeezing, deformation and friction effects of the annular airbag ring 13 caused by the backward movement of the electrical plug interface 12 during vibration, and significantly providing a sealing effect when the electrical plug interface is plugged in.

[0027] Embodiment 2:

[0028] like Figure 4 As shown, on the basis of Example 1, a locking lug structure 15 for locking the electrical plug interface 12 when plugged is provided on the outside of the electrical plug interface 12. Specifically, a clamping hole is provided on the connector that is plugged with the electrical plug interface 12, and the locking lug structure 15 is embedded in the clamping hole when the electrical plug interface 12 is plugged with the connector, so that the electrical plug interface 12 and the connector are locked. It should be noted that due to the vibration of the electrical plug interface when the motorcycle is running, the locking lug structure 15 and the clamping hole will be squeezed and rubbed, resulting in deformation of the locking lug structure 15, thereby affecting the stability of the connection of the electrical plug interface 12, causing the vibration to intensify and cause poor contact.

[0029] The locking lug structure 15 includes a docking seat 151 integrally formed on the outer side of the electrical plug interface, and a clamping portion 152 is slidably sleeved on the docking seat 151. Since the clamping portion 152 is slidably sleeved on the docking seat 151, the clamping portion 152 can be slidably adjusted on the docking seat 151, but cannot be rotatably adjusted. An adjusting screw 153 is spirally penetrated and connected to the docking seat 151, and the bottom end of the adjusting screw 153 is rotatably connected to the docking seat 151.

[0030] Specifically, by arranging the locking lug structure 15 to be connected in combination by the docking seat 151 and the clamping portion 152 through the adjusting screw 153, when the locking lug structure 15 is deformed due to the vibration of the electrical plug interface 12 generated when the motorcycle is running for a long time, the adjusting screw 153 can be manually rotated and adjusted, so that the clamping portion 152 is driven to slide and protrude through the adjusting screw 153, and the deformation of the clamping portion 152 is compensated, thereby providing stability for the electrical plug interface 12 to be connected and locked through the clamping portion 152, and preventing poor contact.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
