Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning damper end caps, specifically a high-sealing automotive air conditioning damper actuator injection molded end cap. Background Technology

[0002] The automotive air conditioning damper actuator is a core component controlling the opening and closing of the air duct. Its end cover, as a crucial part protecting the internal gear transmission system and motor, is of paramount importance. Traditional end covers are mostly simple box-shaped structures, which have the following drawbacks:

[0003] 1. Since most existing end caps are made of plastic, they lack rigidity during use and are prone to slight deformation when working in high-temperature environments for extended periods. This reduces the meshing accuracy of the internal gear components, causing the actuators to jam or generate significant noise.

[0004] 2. At the same time, since the air conditioner damper actuator is one of the most important electronic control units in the air conditioner, the internal circuit of the actuator injection molded end cover is highly integrated and the circuit arrangement is relatively complex. As a result, the wiring of the relatively small internal space of the injection molded end cover is complicated and cumbersome when it is installed and fixed, which leads to the problem of inconvenience when installing and fixing the injection molded end cover. Utility Model Content

[0005] The purpose of this utility model is to provide a high-sealing automotive air conditioning damper actuator injection end cap to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-sealing automotive air conditioning damper actuator injection-molded end cap, including a housing and a sealing cap. A controller is fixedly installed inside the housing, and a drive motor is also fixedly installed inside the housing. A positioning post is fixedly connected to the bottom of the inner cavity of the housing. A compression sleeve is fixedly fitted inside the housing, and a bolt is threaded into the internal thread of the compression sleeve. A reinforcing mechanism is provided inside the housing, the reinforcing mechanism including:

[0007] The first positioning groove is located on the front side of the inner wall of the housing, and the second positioning groove is located on the side of the inner wall of the housing. The first positioning groove is movably fitted with a first reinforcing plate, and the second positioning groove is movably fitted with a second reinforcing plate. The second reinforcing plate is perpendicular to the first reinforcing plate.

[0008] Preferably, the housing is provided with a positioning mechanism, which includes a positioning seat fixedly connected to the bottom of the housing cavity. A limiting post is movably sleeved inside the extrusion sleeve. A clamping seat is fixedly connected to the bottom of the limiting post, and a spring is movably sleeved outside the limiting post. A fixing component is provided outside the sealing cover, and a sealing ring is fixedly sleeved at the top of the inner cavity of the sealing cover.

[0009] Preferably, the fixing component includes a positioning slot, which is formed on the front of the housing, and a locking post is fixedly connected to the bottom of the sealing cover, the locking post being adapted to the positioning slot.

[0010] Preferably, the sealing ring is made of silicone material, and the bottom of the sealing ring is in close contact with the top of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-sealing automotive air conditioning damper actuator injection end cap, by setting a reinforcing mechanism, when the injection end cap needs to be installed and fixed, the first reinforcing plate and the second reinforcing plate are respectively sleeved inside the first positioning groove and the second positioning groove. At this time, the extrusion sleeve is sleeved inside the housing and the bolt is rotated, so that the bolt can drive the extrusion sleeve to extrude the first reinforcing plate, thereby achieving the fixation of the first reinforcing plate and the second reinforcing plate. This makes the first reinforcing plate and the second reinforcing plate reinforce the housing in the horizontal and vertical directions, thus avoiding the problem of deformation of the housing when heated for a long time, which would cause the position of the drive motor to shift. This greatly improves the stability of the injection end cap during use.

[0012] In addition, this high-sealing automotive air conditioning damper actuator injection-molded end cap also features a positioning mechanism. When the controller needs to be installed, the limit post is raised, causing the clamping seat to rise. At this time, the controller wire is sleeved on the top of the positioning seat and the limit post is released, allowing the spring to drive the clamping seat to tightly press against the top of the wire, thus achieving the effect of clamping and fixing multiple wires. This avoids the problem of inconvenient wire harness fixing due to the small internal space of the housing, improving the regularity of the internal space of the injection-molded end cap and facilitating the installation of electrical components inside the injection-molded end cap.

[0024] Please see Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a high-sealing automotive air conditioning damper actuator injection-molded end cap, comprising a housing 1 and a sealing cover 2. A controller 3 is fixedly installed inside the housing 1, and a drive motor 4 is also fixedly installed inside the housing 1. A positioning post 5 is fixedly connected to the bottom of the inner cavity of the housing 1. A compression sleeve 6 is fixedly sleeved inside the housing 1, and a bolt 7 is threaded into the compression sleeve 6. A reinforcing mechanism 8 is provided inside the housing 1. The reinforcing mechanism 8 includes a first positioning groove 81, which is located on the front of the inner wall of the housing 1, and a second positioning groove 82, which is located on the side of the inner wall of the housing 1. A first reinforcing plate 83 is movably sleeved inside the first positioning groove 81, and a second reinforcing plate 84 is movably sleeved inside the second positioning groove 82. The reinforcing plate 84 and the first reinforcing plate 83 are perpendicular to each other. By setting the reinforcing mechanism 8, when the injection molded end cap needs to be installed and fixed, the first reinforcing plate 83 and the second reinforcing plate 84 are respectively fitted into the first positioning groove 81 and the second positioning groove 82. At this time, the extrusion sleeve 6 is fitted into the inside of the housing 1 and the bolt 7 is rotated, so that the bolt 7 can drive the extrusion sleeve 6 to extrude the first reinforcing plate 83, thereby achieving the fixation of the first reinforcing plate 83 and the second reinforcing plate 84. This makes the first reinforcing plate 83 and the second reinforcing plate 84 reinforce the housing 1 in the horizontal and vertical directions, thus avoiding the problem of deformation of the housing 1 when heated for a long time, which would cause the position of the drive motor 4 to shift. This greatly improves the stability of the injection molded end cap during use.

[0025] Please see Figure 4 and Figure 5 The housing 1 has a positioning mechanism 9 inside, which includes a positioning seat 91 fixedly connected to the bottom of the inner cavity of the housing 1. A limiting post 92 is movably sleeved inside the extrusion sleeve 6. A clamping seat 93 is fixedly connected to the bottom of the limiting post 92, and a spring 94 is movably sleeved outside the limiting post 92. A fixing assembly 10 is provided outside the sealing cover 2, and a sealing ring 11 is fixedly sleeved at the top of the inner cavity of the sealing cover 2. By setting the positioning mechanism 9, when the controller 3 needs to be installed, the limiting post 92 is raised, so that... The limiting post 92 drives the clamping seat 93 to lift. At this time, the controller 3 wire is sleeved on the top of the positioning seat 91 and the limiting post 92 is released, so that the spring 94 drives the clamping seat 93 to tightly press against the top of the wire, thereby achieving the effect of clamping and fixing multiple wires, that is, achieving the effect of arranging and positioning multiple wires. This avoids the problem that the small internal space of the housing 1 makes it inconvenient to fix the wire harness, thus improving the regularity of the internal space of the injection molded end cap, thereby bringing convenience to the installation of electrical components inside the injection molded end cap.

[0026] Please see Figure 1 and Figure 2The fixing component 10 includes a positioning slot 101, which is located on the front of the housing 1. A locking post 102 is fixedly connected to the bottom of the sealing cover 2, and the locking post 102 is adapted to the positioning slot 101. By setting the fixing component 10, when the housing 1 is fixed, the sealing cover 2 is sleeved on the top of the housing 1, so that the sealing cover 2 can drive the locking post 102 to be sleeved inside the positioning slot 101. Thus, the locking post 102 can drive the sealing cover 2 to be locked and fixed on the top of the housing 1, thereby achieving the effect of fixed connection between the sealing cover 2 and the housing 1, which brings convenience to the installation and fixing of the injection molded end cap.

[0027] Please see Figure 3 The sealing ring 11 is made of silicone material, and the bottom of the sealing ring 11 is in close contact with the top of the housing 1. By setting the sealing ring 11, when the sealing cover 2 is installed and fixed, the sealing cover 2 can be tightly squeezed and fixed on the top of the sealing ring 11, thereby achieving the filling effect of the gap between the sealing cover 2 and the housing 1, thus avoiding the problem of large abnormal noise when the sealing cover 2 vibrates for a long time, thereby improving the sealing performance of the injection molded end cap.

[0028] Working principle: When the injection-molded end cap needs to be installed and fixed, the first reinforcing plate 83 and the second reinforcing plate 84 are respectively fitted into the first positioning groove 81 and the second positioning groove 82. At this time, the extrusion sleeve 6 is fitted into the inside of the housing 1 and the bolt 7 is rotated, so that the bolt 7 drives the extrusion sleeve 6 to extrude the first reinforcing plate 83, thereby fixing the first reinforcing plate 83 and the second reinforcing plate 84. This makes the first reinforcing plate 83 and the second reinforcing plate 84 reinforce the housing 1 in the horizontal and vertical directions, thus avoiding the deformation of the housing 1 when heated for a long time, which would cause the position of the drive motor 4 to shift. This greatly improves the stability of the injection-molded end cap during use. When the controller 3 needs to be installed, the limit post 92 is lifted, so that the limit post 92 drives the clamping seat 93 to lift. At this time, the controller 3 wire is fitted into the top of the positioning seat 91 and the limit post 92 is released, so that the spring 94 drives the clamping seat 93 to tightly press against the top of the wire, thereby achieving the effect of clamping and fixing multiple wires. This achieves the effect of arranging and positioning multiple wires, avoiding the problem of inconvenient wire harness fixing due to the small internal space of the housing 1. It improves the regularity of the internal space of the injection-molded end cap, thus facilitating the installation of electrical components inside the injection-molded end cap. When the housing 1 is fixed, the sealing cover 2 is fitted onto the top of the housing 1, allowing the sealing cover 2 to drive the locking post 102 to engage inside the positioning slot 101. This allows the locking post 102 to lock the sealing cover 2 onto the top of the housing 1, achieving a fixed connection between the sealing cover 2 and the housing 1. This facilitates the installation and fixing of the injection-molded end cap. During the installation and fixing of the sealing cover 2, it is tightly pressed and fixed onto the top of the sealing ring 11, thus filling the gap between the sealing cover 2 and the housing 1. This avoids the problem of significant abnormal noise during long-term vibration of the sealing cover 2, thereby improving the internal sealing performance of the injection-molded end cap.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
