Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an integrated structure of a button and sealing ring for an automotive electric hatch cover. Background Technology

[0002] Car covers (such as charging port covers and fuel filler caps) are important functional components of the vehicle body. They not only provide shielding and protection, but also undertake multiple responsibilities such as sealing and dust prevention, waterproofing and frost prevention, safety locking, and user interaction.

[0003] For example, CN217812997U discloses a rotary opening charging port cover actuator, which includes a housing, a bottom cover at the bottom of the housing, and a connecting buckle at the top of the housing for connecting with the charging port cover plate. The housing is hollow, and a drive motor is installed on one side of the bottom of the housing. The output shaft of the drive motor is connected to a worm gear. A guide sleeve, an output shaft, and a worm wheel screw are sequentially connected inside the housing. The worm wheel screw has an external thread, and a worm wheel is provided at the bottom of the worm wheel screw. The worm wheel meshes with the worm gear. A sealing ring is provided between the outer wall of the output shaft and the end of the housing.

[0004] However, existing sealing rings can only seal a single area. If multiple areas need to be sealed, multiple sealing rings are required, which makes installation inconvenient. Furthermore, conventional sealing rings are prone to falling off, affecting the sealing effect. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes an integrated structure of button and sealing ring for an electric car hatch.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] An integrated button and sealing ring structure for an automotive electric hatch includes a base housing, an actuator rod inserted into the base housing, a drive assembly for extending and retracting the actuator rod inside the base housing, and a request switch for actuating the drive assembly.

[0008] The control part of the request switch is exposed on the base housing. The base housing has a sliding opening for the actuator rod to extend out, and a sealing ring is provided on the base housing. The sealing ring includes a first sealing part and a second sealing part that engage. The first sealing part covers the control part of the request switch, and the second sealing part is embedded in the sliding opening and abuts against the outer periphery of the actuator rod.

[0009] Preferably, the base housing has a first embedding groove for embedding the first sealing part and a second embedding groove for embedding the second sealing part. With the above improvement, the first sealing part is embedded in the first embedding groove and the second sealing part is embedded in the second embedding groove, so that the sealing ring is installed on the base housing to ensure the sealing between the request switch and the base housing and the actuator.

[0010] Preferably, the sealing ring further includes a connecting portion for connecting the first sealing part and the second sealing part. The connecting portion has a first embedding section that is horizontally embedded in the base housing and a second embedding section that is vertically embedded in the base housing. Through the above improvements, the first sealing part and the second sealing part are connected by the connecting portion, which improves the convenience of sealing ring installation. Furthermore, the first embedding section and the second embedding end are embedded in the base housing in the horizontal and vertical directions, respectively, which greatly improves the stability of the entire sealing ring installation.

[0011] Preferably, the first sealing part forms a mounting cavity into which the control part of the request switch is placed, the second sealing part forms a sliding groove through which the actuator rod passes, and the second sealing part forms an annular abutment part that abuts against the actuator rod. Through the above improvements, the control part of the request switch is placed in the mounting cavity, thereby enabling the first sealing part to be pressed to drive the request switch and ensuring the sealing protection of the request switch. At the same time, the second sealing part forms an annular abutment part that abuts against the outer periphery of the actuator rod, ensuring the sealing between the actuator rod and the base housing.

[0012] Preferably, the sealing ring further includes a reinforcing portion connecting the first sealing portion and the connecting portion. The reinforcing portion is horizontally embedded in the base housing and is perpendicular to the connecting portion. Through the above improvements, the reliability of the sealing ring installation is further enhanced by utilizing the cooperation between the reinforcing portion and the connecting portion.

[0013] Preferably, the reinforcing part has a first reinforcing segment and a second reinforcing segment along the extending direction, and the thickness of the second reinforcing segment is greater than that of the first reinforcing segment. Through the above improvements, the first reinforcing segment and the second reinforcing segment have different thicknesses, thereby increasing the reliability of the connection between the reinforcing part and the base shell.

[0014] Preferably, the first sealing part and the second sealing part are integrally injection molded, and the structural strength of the entire sealing ring is improved through the above improvements.

[0015] Preferably, the drive assembly includes a drive unit, a transmission gear set connected to the output end of the drive unit, and a drive rod meshing with the transmission gear set. The drive rod has a threaded connection section. The actuator is sleeved on the drive rod and threadedly connected to the threaded connection section. The drive rod rotates to drive the actuator to perform telescopic movement. The base housing has a positioning block with a guide protrusion. The outer wall of the actuator has a spiral guide groove for the guide protrusion to be inserted. Through the above improvements, the drive assembly drives the actuator to move, achieving stable and high-thrust rotational ejection to drive the cover to open or close. Compared with the traditional press-and-buckle structure, it has both ice-breaking and unlocking functions, improving the convenience of daily use. The guide protrusion is inserted into the spiral guide groove, so that as the drive rod rotates, the actuator will perform telescopic movement with stable high thrust.

[0016] Preferably, the base housing includes an adjacent control area and a drive area, with a reinforcing connecting rib between the control area and the drive area. The first sealing part is disposed on the control area, and the second sealing part is disposed on the drive area. The reinforcing connecting rib has an embedded mounting groove for the connecting part to be inserted. Through the above improvements, the reinforcing connecting rib strengthens the structure and provides a connection position for the sealing ring. Furthermore, the adjacent arrangement of the two areas reduces the material used for the sealing ring and optimizes the space ratio of the housing.

[0017] Preferably, the base housing is provided with a positioning block, the positioning block is provided with a guide protrusion, and the outer wall of the actuator is provided with a spiral guide groove for the guide protrusion to be inserted. With the above improvements, the guide protrusion is inserted into the spiral guide groove, so that as the drive rod rotates, the actuator will perform telescopic movement and has a stable large thrust.

[0018] Preferably, a micro switch is provided inside the base housing, and an abutment piece is formed on the outer periphery of the actuator rod. When the actuator rod is retracted into the base housing, the abutment piece presses against the micro switch. When the actuator rod extends out of the base housing, the abutment piece moves away from the micro switch. Through the above improvements, the switch is turned on and off by the change in the position of the push rod, accurately determining whether the cover is in a locked (retracted) or released (extended) state, thereby converting mechanical displacement into an electrical signal, thereby improving the vehicle dashboard and linking other systems.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] By dividing the sealing ring into a first sealing part and a second sealing part, the first sealing part covers the control part of the request switch, and the second sealing part is embedded in the sliding port and abuts against the outer periphery of the actuator rod. This not only achieves sealing protection for the request switch at the same time, but also ensures the sealing between the actuator rod and the base housing. Compared with conventional sealing, this not only saves the number of sealing rings and increases installation efficiency, but also makes the installation more stable and prevents the sealing ring from falling off.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0030] like Figure 1-6 As shown, an integrated structure of button and sealing ring 5 for an electric car hatch includes a base housing 1, an actuator 2 inserted on the base housing 1, a drive assembly 3 for driving the actuator 2 to extend and retract inside the base housing 1, and a request switch 4 for driving the drive assembly 3 to operate.

[0031] Specifically, the control part of the request switch 4 is exposed on the base housing 1. The base housing 1 has a sliding opening 1.1 for the actuator 2 to extend out, and a sealing ring 5 is provided on the base housing 1. The sealing ring 5 includes a first sealing part 1.2 and a second sealing part 1.3 that engage. The first sealing part 1.2 covers the control part of the request switch 4, and the second sealing part 1.3 is embedded in the sliding opening and abuts against the outer periphery of the actuator 2.

[0032] By dividing the sealing ring 5 into a first sealing part 1.2 and a second sealing part 1.3, the first sealing part 1.2 covers the control part of the request switch 4, and the second sealing part 1.3 is embedded in the sliding port 1.1 and abuts against the outer periphery of the actuator 2. This not only achieves sealing protection for the request switch 4, but also ensures the sealing between the actuator 2 and the base housing 1. Compared with conventional sealing, this not only saves the number of sealing rings 5 ​​and increases installation efficiency, but also makes the installation more stable and prevents the sealing rings 5 ​​from falling off.

[0033] like Figures 1 to 3 As shown, to further explain the fit between the base housing 1 and the sealing ring 5, the base housing 1 has a first embedding groove 1.4 for the first sealing part 1.2 to be embedded in, and a second embedding groove 1.5 for the second sealing part 1.3 to be embedded in. The first sealing part 1.2 has a mounting cavity 2.3 for the insertion of the control part of the request switch 4. The second sealing part 1.3 has a sliding groove 2.4 through which the actuator 2 passes, and an annular abutment part 2.5 abutting the actuator 2.

[0034] During the installation of the sealing ring 5, it is only necessary to embed the first sealing part 1.2 into the first embedding groove 1.4 and the second sealing part 1.3 into the second embedding groove 1.5, so that the sealing ring 5 is installed on the base housing 1 to ensure the sealing between the request switch 4, the base housing 1 and the actuator 2. The control part of the request switch 4 will be placed in the mounting cavity 2.3, so that the first sealing part 1.2 can be pressed to drive the request switch 4 and ensure the sealing protection of the request switch 4. At the same time, the second sealing part 1.3 forms an annular abutment part 2.5, which abuts against the outer periphery of the actuator 2 to ensure the sealing between the actuator 2 and the base housing 1.

[0035] Specifically, the sealing ring 5 also includes a connecting part 1.6 that connects the first sealing part 1.2 and the second sealing part 1.3. The connecting part 1.6 has a first embedding section 2.1 that is horizontally embedded in the base housing 1 and a second embedding section 2.2 that is vertically embedded in the base housing 1. By connecting the first sealing part 1.2 and the second sealing part 1.3 with the connecting part 1.6, not only can the convenience of installing the sealing ring 5 be improved, but also the first embedding section 2.1 and the second embedding end are embedded in the base housing 1 in the horizontal and vertical directions respectively, which greatly improves the stability of the entire sealing ring 5 installation and prevents the sealing ring 5 from falling off.

[0036] The base housing 1 includes an adjacent control area 5.1 and a drive area 5.2. A reinforcing connecting rib 5.3 is formed between the control area 5.1 and the drive area 5.2. A first sealing part 1.2 is provided on the control area 5.1, and a second sealing part 1.3 is provided on the drive area 5.2. An embedded mounting groove 5.4 for the connecting part 1.6 to be inserted is formed on the reinforcing connecting rib 5. The reinforcing connecting rib 5.3 not only strengthens the structure, but also provides a connection position for the sealing ring 5. The adjacent arrangement of the two areas reduces the material used for the sealing ring 5 and optimizes the space ratio of the housing.

[0037] In addition, the sealing ring 5 also includes a reinforcing part 1.7 that connects the first sealing part 1.2 and the connecting part 1.6. The reinforcing part 1.7 is horizontally embedded in the base housing 1, and the reinforcing part 1.7 is perpendicular to the connecting part 1.6. The cooperation between the reinforcing part 1.7 and the connecting part 1.6 further improves the reliability of the installation of the sealing ring 5.

[0038] The reinforcing part 1.7 has a first reinforcing section 2.6 and a second reinforcing section 2.7 along the extension direction, and the thickness of the second reinforcing section 2.7 is greater than that of the first reinforcing section 2.6, thereby increasing the reliability of the connection between the reinforcing part 1.7 and the base housing 1.

[0039] Preferably, the end of the second reinforcing section 2.7 is rounded to increase the embedding area.

[0040] Preferably, the first sealing part 1.2 and the second sealing part 1.3 are integrally injection molded, which can not only improve the production efficiency of the sealing ring 5, but also improve the structural strength of the entire sealing ring 5.

[0041] like Figures 3 to 6 As shown, to further explain the specific structure of the drive assembly, the drive assembly includes a drive unit 3.1, a transmission gear set 3.2 that is connected to the output end of the drive unit 3.1, and a drive rod 3.3 that meshes with the transmission gear set 3.2. The drive rod 3.3 has a threaded connection section 3.4. The actuator 2 is sleeved on the drive rod 3.3 and threadedly connected to the threaded connection section 3.4. The drive rod 3.3 rotates to drive the actuator 2 to perform telescopic movement.

[0042] During the entire movement of the actuator 2, the drive assembly 3 drives the drive rod 3.3 to rotate, and the drive rod 3.3 drives the actuator 2 to extend and retract, achieving a stable and powerful rotational push-out to drive the cover to open or close. Compared with the traditional press-and-lock structure, it has both ice-breaking and unlocking functions, improving the convenience of users in daily use.

[0043] Furthermore, the base housing 1 is provided with a positioning block 4.1, and a guide protrusion 4.2 is formed on the positioning block 4.1. The outer wall of the actuator 2 is provided with a spiral guide groove 4.3 for the guide protrusion 4.2 to be inserted. When the guide protrusion 4.2 is inserted into the spiral guide groove 4.3, the actuator 2 will rotate and perform telescopic movement as the drive rod 3.3 rotates, and it has a stable large thrust.

[0044] In some other embodiments, a micro switch 4.4 is provided inside the base housing 1, and an abutment piece 4.5 is formed on the outer periphery of the actuator 2. When the actuator 2 is retracted into the base housing 1, the abutment piece 4.5 presses against the micro switch 4.4. When the actuator 2 extends out of the base housing 1, the abutment piece 4.5 moves away from the micro switch 4.4. The switch is turned on and off by the change in the position of the push rod, accurately determining whether the cover is in a locked (retracted) or released (extended) state, thereby converting mechanical displacement into an electrical signal, thereby lifting the vehicle dashboard and linking other systems.

[0045] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
