Description

Technical Field

[0001] This utility model relates to the field of electric damper technology, and in particular to an electric damper transmission structure. Background Technology

[0002] In the automotive industry, the application of electric damper drive structure is crucial for the airflow control of vehicle air conditioning system. However, among the related products currently on the market, electric damper drive devices with a one-to-two structure have many obvious problems and shortcomings.

[0003] Specifically, this type of one-to-two structure has a large number of parts, which directly leads to the complexity of its transmission structure. In actual operation, the complex transmission structure makes it easier for the coordination and movement between the components to deviate and interfere, which in turn makes the abnormal noise generated during the transmission process more obvious. This abnormal noise not only affects the quietness of the vehicle interior and brings a bad experience to the driver and passengers, but may also reflect abnormal wear between transmission components, affecting the service life of the overall structure.

[0004] Furthermore, due to the large number of parts and the complexity of the structure, more raw materials, processing steps, and assembly time are required in the production and manufacturing process, which undoubtedly increases the manufacturing cost of this type of structure. The higher manufacturing cost will be directly reflected in the final price of the product, which is not conducive to improving the product's market competitiveness, but may also put cost pressure on vehicle manufacturers, thereby affecting the market performance of related models. Utility Model Content

[0005] The purpose of this utility model is to provide an electric damper transmission structure that solves the problems of existing one-to-two structures having a large number of parts, complex transmission structure, obvious abnormal noise during transmission, and high manufacturing cost.

[0006] To achieve the above objectives, this utility model provides an electric damper transmission structure, including a housing, a control component, an air guide component, and a connecting component. The control component includes a transmission box, a transmission shaft, a control kit, a transmission crank, and a transmission gear. The transmission box is detachably connected to the housing and located on the outside of the housing. The transmission shaft is rotatably connected to the transmission box and passes through the transmission box. The control kit is connected to the transmission shaft and located inside the transmission box. A control crank is provided on one side of the control kit, and a control gear is also provided on the outside of the control kit. The transmission crank is rotatably connected to the transmission box and cooperates with the control crank. The transmission gear is rotatably connected to the transmission box and meshes with the control gear.

[0007] The control component further includes a damper and a guide vane. The damper is connected to the transmission crank and is located inside the housing. The guide vane is connected to the transmission gear and is located inside the housing.

[0008] The air guide assembly includes an air guide bracket and air guide blades. The air guide bracket is detachably connected to the housing and is located inside the housing. There are multiple air guide blades, which are rotatably connected to the air guide bracket and pass through the air guide bracket.

[0009] The air guide assembly further includes a connecting gear and an air guide gear. The connecting gear is rotatably connected to the air guide blades and is located on the top of the housing. The air guide gear is rotatably connected to the housing and meshes with the connecting gear.

[0010] The connecting assembly includes a sealing gasket and an air outlet plate. The sealing gasket is fixedly connected to the housing and located on the outside of the housing. The air outlet plate is detachably connected to the housing and located on the side of the housing opposite to the sealing gasket.

[0011] This utility model discloses an electric damper transmission structure. The housing connects the device to the vehicle body and provides support. The transmission box supports the control assembly and provides a seal for the transmission structure. The transmission shaft is connected to an external power source to power the control assembly. The control crank is located on one side of the transmission shaft, and the control gear (a half-gear) is located on the other side of the control crank. The transmission crank and the control crank cooperate to control the damper. The transmission gear and the control gear cooperate to control the air guide plate. When control of the damper is required... An external motor drives the transmission shaft to rotate, causing the control crank to insert into the transmission crank, thereby controlling the damper. When the damper does not need to be controlled, but the air guide plate needs to be controlled, the external motor rotates, driving the transmission shaft to rotate. This causes the control crank to control the transmission crank, keeping the damper open. The transmission shaft continues to rotate, causing the control gear to mesh with the transmission gear, facilitating the control of the air guide plate angle. This solves the problems of existing one-to-two structures having a large number of parts, complex transmission structure, obvious abnormal noise during transmission, and high manufacturing cost.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

Figure 2 This is an exploded view of the control component according to the first embodiment of the present invention. Figure 3 This is a schematic diagram of the air guide assembly of the first embodiment of the present invention. The present invention provides an electric damper transmission structure, including a housing 101, a control assembly, an air guide assembly, and a connecting assembly. The control assembly includes a transmission box 102, a transmission shaft 103, a control kit, a transmission crank 106, a transmission gear 107, an air damper 108, and an air guide plate 109. The air guide assembly includes an air guide bracket 110, air guide blades 111, a connecting gear 112, and an air guide gear 113. The connecting assembly includes a sealing gasket 114 and an air outlet plate 115. The aforementioned solution solves the problems of existing one-to-two structures having a large number of parts, complex transmission structure, obvious abnormal noise during transmission, and high manufacturing cost.

[0020] In this specific embodiment, the transmission box 102 is detachably connected to the housing 101 and is located on the outside of the housing 101. The transmission shaft 103 is rotatably connected to the transmission box 102 and passes through the transmission box 102. The control kit is connected to the transmission shaft 103 and is located inside the transmission box 102. A control crank 104 is provided on one side of the control kit, and a control gear 102 is also provided on the outside of the control kit. The transmission crank 106 is rotatably connected to the transmission box 102 and cooperates with the control crank 104. The transmission gear 107 is rotatably connected to the transmission box 102 and meshes with the control gear 105. The air guide assembly and the connecting assembly are respectively connected to the housing 101. The housing 101 is used to connect the device to the vehicle body and provide support for the device. The transmission box 102 provides support for the control assembly and provides a sealing function for the transmission structure. The transmission shaft 103 is connected to an external power source to provide power to the control assembly. The control crank 104 is located on one side of the drive shaft 103, and the control gear 105 is a half gear located on the other side of the control crank 104. The transmission crank 106 cooperates with the control crank 104 to control the damper 108, and the transmission gear 107 cooperates with the control gear 105 to control the air guide plate 109. When the damper 108 needs to be controlled, an external motor drives the drive shaft 103 to rotate, causing the control crank 104 to engage with the transmission shaft 103. Inside the crank 106, the damper 108 is controlled. When the damper 108 does not need to be controlled, but the air guide plate 109 needs to be controlled, the external motor rotates, driving the transmission shaft 103 to rotate. At this time, the control crank 104 controls the transmission crank 106 to keep the damper 108 in an open state. The transmission shaft 103 continues to rotate, causing the control gear 105 to mesh with the transmission gear 107, which facilitates the control of the angle of the air guide plate 109.

[0021] The damper 108 is connected to the transmission crank 106 and is located inside the housing 101. The air guide plate 109 is connected to the transmission gear 107 and is located inside the housing 101. The damper 108 is used to control the air intake volume, and the air guide plate 109 is used to control the air intake angle.

[0022] Secondly, the air guide bracket 110 is detachably connected to the housing 101 and is located inside the housing 101. There are multiple air guide blades 111, which are rotatably connected to the air guide bracket 110 and pass through the air guide bracket 110 respectively. The air guide bracket 110 provides support for the air guide assembly. The air guide blades 111 are used to control the left and right angle of the air intake. The air guide blades 111 are connected by a linkage.

[0023] Furthermore, the connecting gear 112 is rotatably connected to the air guide blade 111 and is located on the top of the housing 101. The air guide gear 113 is rotatably connected to the housing 101 and meshes with the connecting gear 112. The connecting gear 112 is used to drive the air guide blade 111 in the middle. The air guide gear 113 is connected to an external motor to provide power to the air guide assembly.

[0024] Finally, the sealing gasket 114 is fixedly connected to the housing 101 and located on the outside of the housing 101. The air outlet plate 115 is detachably connected to the housing 101 and located on the side of the housing 101 away from the sealing gasket 114. The sealing gasket 114 is used to seal the housing 101 and the air duct, and the air outlet plate 115 is used to guide the airflow.

[0025] Using the electric damper transmission structure of this embodiment, the housing 101 connects the device to the vehicle body and provides support for the device; the transmission box 102 provides support for the control component and provides a seal for the transmission structure; the transmission shaft 103 is connected to an external power source to provide power to the control component; the control crank 104 is located on one side of the transmission shaft 103; the control gear 105 is a half gear located on the other side of the control crank 104; the transmission crank 106 cooperates with the control crank 104 to control the damper 108; the transmission gear 107 cooperates with the control gear 105 to control the air guide plate 109 when control of the damper 108 is required. An external motor drives the transmission shaft 103 to rotate, causing the control crank 104 to insert into the transmission crank 106, thereby controlling the damper 108. When it is not necessary to control the damper 108 but the air guide plate 109 needs to be controlled, the external motor rotates, driving the transmission shaft 103 to rotate. At this time, the control crank 104 controls the transmission crank 106 to keep the damper 108 in an open state. The transmission shaft 103 continues to rotate, causing the control gear 105 to mesh with the transmission gear 107, which facilitates the control of the angle of the air guide plate 109. This solves the problems of existing one-to-two structures having a large number of parts, complex transmission structure, obvious abnormal noise during transmission, and high manufacturing cost.
