[0002] There are a wide variety of cable actuators on the current automotive market. A cable actuator is a device that allows remote release of any latch in a vehicle. After receiving a control signal, the cable actuator converts electricity into mechanical power to pull the cable, which in turn drives the unlocking mechanism. It can be used to unlock mechanisms such as the center armrest, fuel tank cap, door locks, charging ports, and headrests. Depending on the situation, a self-resetting function can be selected.

[0003] In existing technologies, a soft steel wire cable is usually used to pull the load to unlock the device. This method can only unlock the device by pulling and cannot recognize multiple positions. If a motor Hall effect memory function is used to provide real-time feedback on different positions during the push-pull process, the position may be inaccurate due to accumulated tolerances.

Detailed Implementation

[0042] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0043] Please see Figure 1-8 This utility model provides a technical solution: a push-pull actuator, comprising:

[0044] A drive component 100 is provided with an output terminal 100a, the direction of movement of the output terminal 100a being the drive direction;

[0045] A cable assembly 200 includes a sleeve 201 and a rigid member 202. The rigid member 202 is configured to be movably connected to the sleeve 201 along the driving direction. The output end 100a is driven to be connected to the rigid member 202.

[0046] The position feedback component 300 includes a support member 301 and a sliding potentiometer 302. The support member 301 supports and connects the drive component 100, the sleeve 201, and the sliding potentiometer 302. The sliding potentiometer 302 is provided with a slider 3021, which is adapted to move along the drive direction on the sliding potentiometer 302. The slider 3021 is connected between the rigid member 202 and the output terminal 100a.

[0047] This push-pull actuator replaces the flexible cable of the prior art with a rigid component 202, enabling unlocking in both push and pull modes. The rigid component 202 is driven to move within the sleeve 201 by the output terminal 100a of the drive component 100. The linear sliding potentiometer 302 located between the rigid component 202 and the output terminal 100a can provide real-time feedback on various different positions of the output structure. This avoids the position inaccuracy problem caused by the cumulative tolerance of the traditional motor Hall memory function, and also eliminates the need for external limit switches.

[0048] It should be noted that the sliding potentiometer 302 is existing technology. The slider 3021 outputs different voltages at different positions of the sliding potentiometer 302. The position of the rigid component 202 can be obtained by reading the voltage data.

[0049] In the driving direction, the travel of the slider 3021 on the linear potentiometer 302 matches the travel of the rigid member 202 on the sleeve 201. Specifically, see... Figure 10 and Figure 11The cable assembly 200 has at least two working states: the maximum extension state and the maximum drawout state. When the cable assembly 200 is in the maximum extension state, the side of the rigid member 202 near the output end 100a is close to the side of the sleeve 201 near the output end 100a. At this time, the slider 3021 is located on the side of the linear potentiometer 302 away from the drive assembly 100. When the cable assembly 200 is in the maximum drawout state, the side of the rigid member 202 near the output end 100a is away from the side of the sleeve 201 near the output end 100a. At this time, the slider 3021 is located on the side of the linear potentiometer 302 near the drive assembly 100.

[0050] See Figure 3 Regarding the specific structure of the cable assembly 200, the rigid member 202 is a cylindrical rigid steel wire. The rigid member 202 is movably connected to the inner side of the sleeve 201. In use, the rigid member 202 can output thrust and apply tension to achieve bidirectional load operation. One end of the rigid member 202 in the length direction is connected to the output end 100a of the drive assembly 100, and the other end of the rigid member 202 in the length direction is connected to the external frame.

[0051] See Figure 7 and 8 Furthermore, the push-pull actuator also includes an adapter 400, through which the output terminal 100a, the rigid member 202, and the slider 3021 are all connected. The adapter 400 and the linear potentiometer 302 are both concealed within the support member 301. The adapter 400 simultaneously connects the output terminal 100a, the rigid member 202, and the slider 3021, achieving integrated installation with the support member 301. This results in a small overall size for the actuator, avoiding the need for external limit switches that would increase its overall space requirements.

[0052] Furthermore, the output end 100a, the rigid member 202, and the slider 3021 are detachably connected to the adapter 400.

[0053] Specifically, the adapter 400 is a cylindrical adapter 400, the axial direction of the adapter 400 coincides with the driving direction, a mounting groove 401 is formed on one side of the adapter 400 in the radial direction, the mounting groove 401 connects the two sides of the adapter 400 in the axial direction, a contour groove 4011 is formed on the inner wall of the mounting groove 401 on the side in the driving direction, and a limiting groove 4012 is formed on the other side of the inner wall of the mounting groove 401 in the driving direction; one end of the rigid member 202 connected to the output end 100a extends radially to form a die-casting head 2. 021, the die-casting head 2021 matches the contouring groove 4011, and the output end 100a matches the limiting groove 4012. Preferably, the contouring groove 4011 and the die-casting head 2021 are interference-fitted, and the output end 100a and the limiting groove 4012 are interference-fitted. In use, the die-casting head 2021 is inserted into the contouring groove 4011 of the adapter 400 by dimensional constraints to prevent radial dislodgement, and can push the rigid member 202 in the driving direction. The output end 100a is inserted into the limiting groove 4012 of the adapter 400 by dimensional constraints. Optionally, the die-casting head 2021 is cylindrical or spherical.

[0054] The adapter 400 has a terminal slot 402 formed on its radially outer wall. The terminal slot 402 matches the slider 3021. Preferably, the terminal slot 402 and the slider 3021 are interference-fitted. In one embodiment of the present invention, both the terminal slot 402 and the slider 3021 are rectangular.

[0055] Furthermore, in the radial direction of the adapter 400, the size of the mounting groove 401 is not smaller than the size of the rigid member 202. Preferably, in the radial direction of the adapter 400, the size of the mounting groove 401 is slightly larger than the size of the rigid member 202. This is to facilitate the insertion of the rigid member 202 into the mounting groove 401 and prevent it from coming out.

[0056] See Figure 3-8 Regarding the connection structure between the support member 301, the drive assembly 100, the sleeve 201, and the linear potentiometer 302: The support member 301 is detachably connected to the drive assembly 100 on one side in the drive direction, and detachably connected to the sleeve 201 on the other side in the drive direction.

[0057] For details, see Figure 4 and 5The support member 301 has a support cavity 3011. The support member 301 has a support opening 3012 on one side perpendicular to the driving direction, which connects the inside and outside of the support cavity 3011. This allows the support member 301 to be fitted onto the connection between the output end 100a and the cable assembly 200 in a manner perpendicular to the driving direction. The support opening 3012 has a driving groove 3013 and a cable groove 3014 respectively on the middle part of its two sides in the driving direction. The cross-sectional shape of the driving groove 3013 and the cable groove 3014 is U-shaped. The driving assembly 100 has a housing 101. The output end 100a is located on the housing 101. The housing 101 and the driving groove 3013 are interference-fitted. The cable groove 3014 and the sleeve 201 are interference-fitted on the side near the driving assembly 100.

[0058] Furthermore, an annular groove 2011 is formed on the radial outer wall of the sleeve 201. The groove 2011 is arranged close to the drive assembly 100, and the inner wall of the groove 2011 is interference-fitted with the inner wall of the cable groove 3014. Even further, one groove 2011 is provided on each of the two sides of the sleeve 201 along its axial direction. Figure 3 As can be seen, the cross-sectional shape of the groove 2011 on the sleeve 201 is I-shaped. In use, the sleeve 201 can be radially interference-fitted with the support 301 to maintain connection with the groove 2011.

[0059] For ease of installation, the movable distance of the rigid member 202 within the sleeve is greater than the movable distance of the rigid member 202 within the support cavity 3011 in the driving direction.

[0060] See Figure 4 and 5The sliding potentiometer 302 is detachably installed within the support cavity 3011. Specifically, the bottom wall of the support cavity 3011 and the sliding potentiometer 302 are connected by snap fasteners 3022. The snap fasteners 3022 are divided into multiple groups, with adjacent groups arranged at intervals along the driving direction. Each group contains multiple snap fasteners 3022, which are arranged perpendicular to the driving direction on both sides of the sliding potentiometer 302. In one embodiment of this invention, the number of snap fasteners 3022... There are six clips 3022 in total. The clips 3022 are divided into three groups. The three groups of clips 3022 are arranged at equal intervals in the driving direction. The clips 3022 in the middle group are set close to the center of the sliding potentiometer 302. There are two clips 3022 in each group. The clips 3022 in each group are distributed on both sides of the center of the sliding potentiometer 302. In use, the sliding potentiometer 302 is fixed to the support member 301 through the clips 3022 and is built into the support member 301, achieving the effect of small size and compact structure.

[0061] See Figure 1 Regarding the specific structure of the drive component 100, the drive component 100 includes:

[0062] Housing 101, wherein a power source 102 is installed inside the housing 101;

[0063] A lead screw 103 is provided with a transmission unit 104, which is connected to the power source 102. The power source 102 can drive the lead screw 103 to rotate via the transmission unit 104.

[0064] Nut 105, one end of which is threaded onto lead screw 103, and nut 105 is capable of horizontal reciprocating along the axial direction of lead screw 103. The other end of nut 105 is the output end 100a.

[0065] Furthermore, the drive component 100 also includes:

[0066] An automatic return unit is disposed on the end of the lead screw 103 away from the nut 105. When the power source 102 is activated or not activated, the automatic return unit can drive the lead screw 103 to rotate automatically, thereby moving the nut 105 to reset.

[0067] In one embodiment of this utility model, the automatic return unit is a torsion spring. When the power source 102 is not activated, the torsion spring can drive the lead screw 103 to rotate automatically, thereby moving the nut 105 to reset.

[0068] Optionally, the power source 102 is a motor capable of outputting a certain torque;

[0069] The housing 101 includes a box body and a box cover. The box body and the box cover are fastened together to form a space for the transmission unit 104 to move. Preferably, the box body and the box cover are connected by positioning buckles 3022 arranged circumferentially.

[0070] It should be noted that, in one embodiment of this utility model, the structure of the drive component 100 is the same as that of a small electric unlocking actuator with self-resetting function disclosed in Chinese utility model patent with publication number CN215255392U, which is prior art and will not be described in detail here.

[0071] See Figure 12 An electrical opening 1011 is provided on the housing 101, and the electrical wiring harness connected to the power source 102 is configured to enter and exit the housing 101 through the electrical opening 1011.

[0072] The support member 301 has an output opening 3015 that connects the inside and outside, and the wire harness on the linear potentiometer 302 is configured to enter and exit the support member 301 through the output opening 3015.

[0073] The power-on opening 1011 and the output opening 3015 are located on the same side perpendicular to the driving direction to facilitate wiring and subsequent maintenance.

[0074] See Figure 9 The assembly method of this push-pull actuator is as follows:

[0075] 1. The sliding potentiometer 302 is installed on the inner side of the support 301 via the clips 3022 on both sides;

[0076] 2. Insert the die-casting head 2021 on the rigid member 202 into the contour groove 4011 on the adapter 400 to prevent the rigid member 202 from coming out radially, and to push the rigid member 202 in the driving direction;

[0077] 3. Insert the output terminal 100a into the limiting slot 4012 on the adapter 400;

[0078] 4. In a manner perpendicular to the driving direction, the support member 301 is fitted onto the outside of the adapter 400 through the support port 3012 on the support member 301, wherein the slider 3021 is inserted into the terminal groove 402 on the adapter 400, the gearbox is inserted into the drive groove 3013 on the support member 301, and the sleeve 201 is inserted into the cable groove 3014 on the support member 301, thereby realizing the connection between the drive assembly 100, the cable assembly 200 and the position feedback assembly 300.

[0079] How to use:

[0080] After the drive component 100 is powered on, the output terminal 100a pushes the rigid component 202 to move in the driving direction. At the same time, it pushes the slider 3021 on the sliding potentiometer 302 to move through the adapter 400, changing the resistance of the sliding potentiometer 302, so that the voltage of the sliding potentiometer 302 changes, and the output displacement and voltage curve are obtained, thereby realizing the feedback of position change during product operation.

[0081] When the drive component 100 is powered on in reverse, the output terminal 100a of the drive component 100 moves in the reverse direction, pushing the slider 3021 on the linear potentiometer 302 to move in the reverse direction, thereby obtaining the output displacement and voltage curve. If the drive component 100 is equipped with an automatic recovery unit, the output terminal 100a of the drive component 100 can move in the reverse direction by turning off the power to the drive component 100, thereby pushing the slider 3021 on the linear potentiometer 302 to move in the reverse direction.

[0082] It should be noted that the operating direction and voltage relationship of the output terminal 100a on the drive component 100 can be adaptively adjusted according to the situation.

[0083] In one application scenario, the air cushion adjustment of the truck driver's seat is manually adjustable. A handle switch is set on the side of the seat. Adjusting the handle up and down will open and close the air pump valve, thereby adjusting the shock absorption of the air cushion seat. This push-pull actuator replaces the manual button adjustment, and electric operation replaces manual operation, making it faster and more convenient.

[0084] In summary, the output end of the drive component in this push-pull actuator drives the cable assembly, and the linear potentiometer is integrated into the support component. It can detect the interlocking stroke position with high precision and provide real-time feedback of the position of the output structure to the vehicle body. The integrated installation is small in size and simple and convenient.

[0085] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
