Description

Technical Field

[0001] This utility model relates to a shock-absorbing sealing block structure for a locking actuator. Background Technology

[0002] The charging port cover is a component installed on new energy vehicles to close the charging interface. The charging port cover typically has a locking actuator. The locking actuator's locking components include a locking rod, a spring that moves up and down with the locking rod, and a locking structure that locks or unlocks the charging port cover. When the charging port cover needs to be locked, the locking rod is pressed into the actuator, engaging with the locking structure and compressing the spring. When the charging port cover needs to be unlocked, the locking rod is pressed again to disengage from the locking structure, and the spring returns the locking rod to its original position. Currently, the locking actuators are prone to colliding with surrounding structures when the spring moves up and down with the locking rod, producing noise and potentially causing malfunctions.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown, a locking actuator shock-absorbing sealing block structure includes a housing 1 and a top cover 2 that cooperate with each other. The housing 1 includes a shell 11 and a bottom shell 12 that cooperate with each other.

[0022] The housing 11 includes a first receiving cavity 111 and a second receiving cavity 112. A locking member 3 is provided in the first receiving cavity 111, and a motor is provided in the second receiving cavity 112. The top cover 2 is provided with a sleeve that cooperates with the locking member 3. A positioning groove 113 is provided on the inner wall of the first receiving cavity 111, and an upwardly protruding protrusion 121 is provided on the inner side of the bottom shell 12.

[0023] The locking component 3 includes a locking rod 31, with a spring 32 connected to the lower end of the locking rod 31. The top end of the spring 32 abuts against the locking rod 31, and the bottom end abuts against the inner side of the bottom shell 12. A locking plate 33 that cooperates with the locking rod 31 is provided inside the spring 32. The locking rod 31 can slide up and down in the first receiving cavity 111. When it is necessary to lock the fuel tank cover or the charging port cover, press the top of the locking rod 31, and the locking rod 31 moves downward axially, compressing the spring 32. When it moves to a certain position, the locking rod 31 cooperates with the locking plate 33 to lock. When it is necessary to unlock, press the locking rod 31 again, and the locking rod 31 unlocks on the locking plate 33 and resets with the help of the elastic force of the spring 32.

[0024] A base plate 4 is provided above the base shell 12. The base plate 4 has a through hole to allow the spring 32 to pass through. A shock-absorbing structure 5 is provided on the base plate 4. The shock-absorbing structure 5 includes a flat pad 51 and a shock-absorbing ring 52 disposed above the flat pad 51. The flat pad 51 and the shock-absorbing ring 52 are integrally formed. The shock-absorbing ring 52 is sleeved on the outside of the spring 32. The shock-absorbing ring 52 has a through-hole structure, allowing the spring 32 to pass through and abut against the inside of the base shell 12. The bottom of the flat pad 51 is fitted and fixed to the base plate 4 to provide a sealing and waterproof function. The flat pad 51 is also provided with positioning holes 511 that cooperate with the protrusion 121 to prevent the shock-absorbing structure 51 from being installed backwards during assembly; positioning blocks 521 that cooperate with positioning grooves 113 are provided on opposite sides of the outer wall of the shock-absorbing ring 52; a fixing block 522 that engages with the lower end slide groove of the locking plate 33 is also provided on the outer wall of the shock-absorbing ring 52. When the spring 32 extends or retracts, the shock-absorbing ring 52 can prevent the spring 32 from colliding with other surrounding structures and making noise, thus playing a role in shock absorption and noise reduction.

[0025] The shock-absorbing sealing block structure of the locking actuator of this utility model has a shock-absorbing structure 5 set on the base plate 4. The shock-absorbing structure 5 is provided with a shock-absorbing ring 52 which is sleeved on the outside of the spring 32. This prevents the spring 32 from colliding with other structures and making noise when it extends and retracts, thus playing a role in shock absorption and noise reduction, reducing the collision rate and thereby reducing the damage rate.

[0026] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
