Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more specifically, to an electric connection self-locking mechanism. Background Art

[0002] With the development of the automotive industry, automotive safety has attracted more and more attention. The parking self-locking mechanism of an automobile is a part of the vehicle controller and is also an important mechanism affecting parking safety. The safety and reliability requirements of the parking self-locking mechanism are relatively high. Most of the existing parking self-locking mechanisms adopt a pressing type elastic self-locking mechanism. There is a pushable button, which is provided with an elastic member, a slider and a locking rod inside. The slider is provided with a locking groove. When the user presses the button, the button drives the slider to move inward, and the locking rod moves relative to the locking groove. After the user releases the button, the locking rod hooks the locking position on the locking groove to lock. When the user presses the button again, the locking rod disengages from the locking position and continues to move relative to the locking groove to return to the initial position, and the mechanism is unlocked. This kind of structure requires the locking rod to reciprocate in the locking groove. When the operation speed is too fast, the locking rod has the risk of disengaging from the locking groove. At the same time, when the locking rod is locking, it needs to move into the locking position and then disengage from the locking position. The process is very likely to cause jamming, and there is a situation where the locking rod cannot slide smoothly and cannot be unlocked. Moreover, when the locking rod is locking, it is subjected to the pulling force of the spring, and it is easy to be deformed after long-term use, which will cause the mechanism to be stuck and fail, and it is not reliable and stable enough in use. In addition, during the use of an automobile, there is often a situation where the user gets out of the car without shifting the gear to the parking gear after parking. When the vehicle is locked, the vehicle gear is not in the parking gear, which is likely to cause danger. Summary of the Utility Model

[0003] In order to overcome the defect that the existing parking self-locking mechanism of an automobile in the above-mentioned prior art is prone to jamming or jamming and is not stable and reliable enough, the utility model provides an electric connection self-locking mechanism to prevent jamming during use and improve the stability and reliability of the mechanism.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: an electrically connected self-locking mechanism, comprising: a bracket, an operating rod rotatably connected to the bracket, a first driving member connected to the bracket, a rotating member rotatably connected to the bracket, a first slider slidably connected to the bracket, a reset member connected to the first slider, a first sensor connected to the operating rod or the bracket, and a control member connected to the first driving member signal; the operating rod is provided with a first abutment portion, and the first slider is provided with a second abutment portion for abutting with the first abutment portion; the first sensor is connected to the first driving member signal, and the first sensor is triggered when the operating rod is rotated to a set position, the first driving member is used to push the rotating member to rotate, the rotating member is connected to the first slider and drives the first slider to move, the reset member drives the first slider to move and then resets, and when the first slider moves to the set position, the second abutment portion abuts against the first abutment portion and then locks the operating rod.

[0005] The self-locking mechanism is triggered by an operating rod. After the operating rod rotates to a set position relative to the bracket, the first sensor is triggered. The first sensor transmits a signal to the first driving member. The first driving member drives the rotating member to rotate, and then drives the first slider to slide, so that the second abutment on the first slider abuts against the first abutment on the operating rod, and the first driving member remains stationary after being driven, so that the operating rod is locked and cannot be reset, thereby completing the self-locking action. When unlocking is required, a signal is sent through the control member to reset the first driving member. During the process, the reset member drives the first slider to reset, and the first slider will also drive the rotating member to rotate in the opposite direction, so that the rotating member is also reset. After the first slider is reset, the second abutment is separated from the first abutment, and the operating rod is no longer restricted by the first slider, so that the operator can rotate the operating rod to reset, thereby releasing the lock. The rotating member is used as the transmission member of the first driving member and the first slider. The first driving member is pushed and rotated during the locking process, and the reset member and the first slider are pushed and rotated during the unlocking process. The main action in both operations is to push the rotating member, and no special slot or locking position is set. Compared with the prior art, the structure is simpler, the friction between the components is smaller, and the jamming and stuck phenomena are prevented, and the stability and reliability of the self-locking mechanism are improved; at the same time, in the prior art, the operator rotates the operating rod to the set position and then presses the push-type elastic self-locking mechanism to lock. The self-locking mechanism can automatically lock after the operating rod is rotated to the set position, eliminating the operation of pressing and locking once, and is more convenient to operate. Furthermore, a guide surface is provided on the second abutting portion, thereby further preventing the second abutting portion from jamming when sliding relative to the first abutting portion.

[0006] Among them, the control member can adopt a common button switch or be integrally arranged with the brake pedal. When the brake pedal is depressed, the switch is triggered, thereby resetting the first driving member, or other triggering methods well-known in the art can be adopted; the first driving member can be pushed by a linear driving member or a rotary driving member such as a motor cooperating with a cam; the reset member can adopt an elastic member or refer to the solution of the first driving member; the first sensor can adopt a distance sensor, a contact sensor, a Hall sensor, etc. The Hall sensor generally includes a magnet part and an induction part. When the Hall sensor is adopted, the magnet part is arranged on the operating rod or the bracket, and the induction part is arranged at the corresponding position on the bracket or the operating rod; between the first driving member and the rotating member, and between the first slider and the rotating member, abutting connection or rotating connection can be adopted. Abutting connection is preferably selected, which can further reduce friction and further reduce jamming.

[0007] Preferably, the rotating member is in the shape of a seesaw, and arc-shaped grooves are respectively provided on both sides. Arc-shaped protruding parts for abutting against the arc-shaped grooves are respectively provided on the driving end of the first driving member and the first slider.

[0008] Arc-shaped protruding parts are arranged on the driving end of the first driving member and the first slider, and arc-shaped grooves are arranged on the rotating member. The arc-shaped protruding parts abut against the arc-shaped grooves to reduce friction and improve the smoothness of transmission. Specifically, the arc-shaped protruding parts can be arc-shaped protrusions similar to a U shape, or spherical or quasi-spherical protrusions. The arc-shaped groove is specifically a groove with an arc-shaped bottom surface similar to a U shape. The arc centers of the above-mentioned arc-shaped protrusions and arc-shaped bottom surfaces are parallel to the rotation center of the rotating member.

[0009] Preferably, it further includes a limiting frame slidably connected to the first slider. A first limiting block for preventing the limiting frame from detaching from the first slider is provided on the first slider; the reset member is an elastic reset member, and the reset member is arranged between the limiting frame and the first slider. The limiting frame abuts against the bracket, and when the rotating member drives the first slider to move, the reset member is compressed.

[0010] The limiting frame is connected to the first slider, and under the limiting action of the first limiting block, the limiting frame will not detach from the first slider. The reset member is an elastic reset member and is arranged between the first slider and the limiting frame. Thus, the first slider, the reset member, and the limiting frame can form a sub-assembly, which is convenient for installation. The limiting frame abuts against the bracket. When the first slider is pushed by the rotating member, the reset member is compressed and stores energy. When the first driving member is reset, the reset member extends and drives the first slider and the rotating member to be reset. Setting the reset member as an elastic reset member can reduce costs. Further, a guide post is provided on the limiting frame, and the reset member is sleeved on the guide post to prevent the reset member from coming off.

[0011] Preferably, the first driving member is a solenoid valve.

[0012] Setting the first driving member as a solenoid valve can reduce costs, save installation space, and make the structure more compact.

[0013] Preferably, it further includes a driving device connected to the bracket, a second sensor for detecting whether there is someone in the cab, and a processor. The first sensor, the second sensor, and the driving device are respectively signal-connected to the processor, and the driving device is used to drive the operating lever to rotate and trigger the first sensor.

[0014] The second sensor is signal-connected to the driving device. When the user parks and leaves the vehicle and does not shift the vehicle gear to the parking gear, the second sensor detects that there is no one in the cab and transmits a signal to the processor. At this time, the processor determines whether the operating lever is in the locked state, that is, whether the vehicle is in the parking gear, according to the signal of the first sensor. If the operating lever is not in the locked state, the driving device is commanded to drive, driving the operating lever to rotate to a set position and trigger the first sensor, and then triggering the first driving member to lock the operating lever, and further switching the vehicle to the parking gear to ensure parking safety.

[0015] Preferably, the driving device includes a second driving member connected to the bracket, a transmission assembly connected to the driving end of the second driving member, and a cam member connected to the transmission assembly. The second driving member drives the cam member to rotate through the transmission assembly, and when the cam member rotates, it drives the operating lever to rotate and trigger the first sensor.

[0016] The second driving member is a rotary driving member, preferably a motor. The second driving member drives the cam member to rotate through the transmission assembly. When the cam member rotates, it pushes or drives the operating lever to rotate, so that the operating lever rotates to a set position and triggers the first sensor.

[0017] Preferably, the driving device further includes a second slider slidably connected to the bracket; one end of the second slider abuts against the cam member, and the other end abuts against the operating lever. The second slider is respectively provided with a second limiting block and a third limiting block for preventing the second slider from detaching from the bracket. When the second slider extends to the set position, the second limiting block abuts against the bracket, and when the second slider retracts to the set position, the third limiting block abuts against the bracket.

[0018] The second slider is arranged for transmission, so that one end of the cam member abuts against the second slider, and the other end of the second slider abuts against the operating lever. The wear caused by friction is set between the cam member and the second slider, reducing the maintenance cost. At the same time, the second limiting block and the third limiting block are provided to limit the second slider on the bracket, which further facilitates installation and also prevents the second slider from moving excessively, further avoiding jamming.

[0019] Preferably, the driving device further includes at least two ring members rotatably connected to the cam member. The ring members are snap-fitted on the bracket, and the cam member is indirectly rotatably connected to the bracket through the ring members.

[0020] The ring member is snap-fitted with the bracket and fixed relative to the bracket. The cam member is rotatably connected to the ring member, controlling the damage caused by rotational friction of the cam member between the ring member and the cam member, reducing the maintenance cost, improving the smoothness of rotation of the cam member, and facilitating the installation of the cam member. Among them, the ring member can be a general cylindrical ring member, with a clearance fit with the cam member; or a bearing can be used, with an interference fit with the cam member. Specifically, the cam member includes a cam and a rod, and the rod is rotatably connected to the ring member.

[0021] Preferably, the transmission assembly includes a worm connected to the second driving member and a worm wheel connected to the cam member, and the worm meshes with the worm wheel.

[0022] Using a worm and worm wheel in the transmission assembly can ensure transmission stability, and the worm and worm wheel also have a self-locking function, with better use effects. Specifically, the second driving member drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel is fixedly connected to the cam member, thereby driving the cam member to rotate.

[0023] Preferably, the driving device further includes a magnetic member installed on the side of the worm wheel and a third sensor installed on the bracket. The third sensor detects the rotation angle of the cam member by detecting the rotation angle of the magnetic member.

[0024] Through the rotation of the magnetic member, the third sensor detects the angular change of the magnetic pole of the magnetic member, and then judges the rotation angle of the cam member to ensure that the cam member can rotate according to the setting.

[0025] Compared with the prior art, the beneficial effects of the present utility model are:

[0026] The first driving member drives the rotating member to rotate, thereby driving the first slider to move, and then pressing against the operating rod for locking. When unlocking, the first slider is driven by the reset member to reset and unlock. The actions during locking and unlocking are both to push the rotating member, and no special slots or locking positions are provided, greatly reducing the friction between components. Moreover, the rotating member uses its own rotation method for power transmission, the overall power transmission is smooth, and there is no structure that will cause jamming, avoiding the situation of jamming or jamming, and improving the stability and reliability of the mechanism.

[0037] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0038] Embodiment 1

[0039] As Figures 1-7 shown, the electric connection self-locking mechanism includes: a bracket 1, an operating rod 2 rotatably connected to the bracket 1, a first driving member 3 connected to the bracket 1, a rotating member 4 rotatably connected to the bracket 1, a first slider 5 slidably connected to the bracket 1, a reset member 6 connected to the first slider 5, a first sensor 7 connected to the operating rod 2 or the bracket 1, and a control member 8 signal-connected to the first driving member 3; a first abutting portion 201 is provided on the operating rod 2, and a second abutting portion 501 for abutting against the first abutting portion 201 is provided on the first slider 5; the first sensor 7 is signal-connected to the first driving member 3, and when the operating rod 2 rotates to a set position, the first sensor 7 is triggered. The first driving member 3 is used to push the rotating member 4 to rotate. The rotating member 4 is connected to the first slider 5 and drives the first slider 5 to move. The reset member 6 drives the first slider 5 to move to achieve reset. When the first slider 5 moves to the set position, the second abutting portion 501 abuts against the first abutting portion 201 to lock the operating rod 2.

[0040] The self-locking mechanism is triggered by the operating rod 2. After the operating rod 2 rotates to the set position relative to the bracket 1, the first sensor 7 is triggered. The first sensor 7 transmits a signal to the first driving member 3. The first driving member 3 drives the rotating member 4 to rotate, and then drives the first sliding block 5 to slide, so that the second abutting portion 501 on the first sliding block 5 abuts against the first abutting portion 201 on the operating rod 2, and the first driving member 3 remains stationary after being driven, so that the operating rod 2 is locked and cannot be reset, thereby completing the self-locking action. When unlocking is required, a signal is sent through the control member 8 to reset the first driving member 3. During the process, the reset member 6 drives the first sliding block 5 to reset, and the first sliding block 5 will also drive the rotating member 4 to rotate in the opposite direction, so that the rotating member 4 is also reset. After the first sliding block 5 is reset, the second abutting portion 501 is separated from the first abutting portion 201, and the operating rod 2 is no longer restricted by the first sliding block 5, so that the operator can rotate the operating rod 2 to reset, thereby releasing the lock. The rotating member 4 is used as the transmission member of the first driving member 3 and the first slider 5. The first driving member 3 is pushed and rotated during the locking process, and the reset member 6 and the first slider 5 are pushed and rotated during the unlocking process. The main action in both operations is to push the rotating member 4. No special slot or locking position is set. Compared with the prior art, the structure is simpler, the friction between the components is smaller, and the jamming and jamming phenomenon are prevented, and the stability and reliability of the self-locking mechanism are improved. At the same time, in the prior art, the operator presses the push-type elastic self-locking mechanism to lock after rotating the operating rod 2 to the set position. The self-locking mechanism can automatically lock after the operating rod 2 is rotated to the set position, eliminating the operation of pressing and locking once, and is more convenient to operate. Further, a guide surface is provided on the second abutting portion 501, so as to further prevent the jamming of the second abutting portion 501 when sliding relative to the first abutting portion 201.

[0041] Among them, the control member 8 can be an ordinary button switch, or an integrated setting of the brake pedal. When the brake pedal is stepped on, the switch is triggered, thereby resetting the first drive member 3, or other triggering methods known in the field can be adopted; the first drive member 3 can be pushed by a linear drive member, or a rotating drive member such as a motor and a cam can be used to push it; the reset member 6 can be an elastic member, or refer to the scheme of the first drive member 3; the first sensor 7 can be a distance sensor, a contact sensor or a Hall sensor, etc. The Hall sensor generally includes a magnet part and a sensing part. When the Hall sensor is used, the magnet part is arranged on the operating rod 2 or the bracket 1, and the sensing part is arranged at the corresponding position of the bracket 1 or the operating rod 2; the first drive member 3 and the rotating member 4, and the first slider 5 and the rotating member 4 can adopt abutment connection or rotation connection, and abutment is preferred to further reduce friction and further reduce jamming.

[0042] Advantages of this embodiment: The first driving member 3 drives the rotating member 4 to rotate, thereby driving the first slider 5 to move, and then pressing against the operating rod 2 for locking. When unlocking, the reset member 6 drives the first slider 5 to reset and unlock in the reverse direction. The actions during locking and unlocking are both to push the rotating member 4, and no special slots or locking positions are provided, greatly reducing the friction between components. Moreover, the rotating member 4 uses its own rotation method for power transmission, the overall power transmission is smooth, and there is no structure that will cause jamming, avoiding jamming or jamming situations and improving the stability and reliability of the mechanism.

[0043] Embodiment 2

[0044] As Figures 1-7 shown, based on Embodiment 1, the difference from Embodiment 1 is that:

[0045] The rotating member 4 is in the shape of a seesaw, and arc-shaped grooves 401 are respectively provided on both sides. Arc-shaped protrusion parts 9 for abutting against the arc-shaped grooves 401 are respectively provided on the driving end of the first driving member 3 and the first slider 5. It also includes a limiting frame 10 slidably connected to the first slider 5. A first limiting block 502 for preventing the limiting frame 10 from detaching from the first slider 5 is provided on the first slider 5; the reset member 6 is an elastic reset member, and the reset member 6 is arranged between the limiting frame 10 and the first slider 5. The limiting frame 10 abuts against the support 1, and when the rotating member 4 drives the first slider 5 to move, the reset member 6 is compressed. The first driving member 3 is a solenoid valve.

[0046] Arc-shaped protrusion parts 9 are provided on the driving end of the first driving member 3 and the first slider 5, and arc-shaped grooves 401 are provided on the rotating member 4. The arc-shaped protrusion parts 9 abutting against the arc-shaped grooves 401 reduce friction and improve the smoothness of transmission. Specifically, the arc-shaped protrusion parts 9 can be arc-shaped protrusions similar to a U shape, or protrusions in the shape of a sphere or a quasi-sphere. The arc-shaped groove 401 is specifically a groove with an arc-shaped bottom surface similar to a U shape. The arc centers of the above-mentioned arc-shaped protrusions and arc-shaped bottom surfaces are all parallel to the rotation center of the rotating member 4. The limiting frame 10 is connected to the first slider 5, and under the limiting action of the first limiting block 502, the limiting frame 10 will not detach from the first slider 5. The reset member 6 is an elastic reset member and is arranged between the first slider 5 and the limiting frame 10. Thus, the first slider 5, the reset member 6, and the limiting frame 10 can form a small component, which is convenient for installation. The limiting frame 10 abuts against the support 1. When the first slider 5 is pushed by the rotating member 4, the reset member 6 is compressed and stores energy. When the first driving member 3 resets, the reset member 6 extends and drives the first slider 5 and the rotating member 4 to reset. Setting the reset member 6 as an elastic reset member can reduce costs. Further, a guide post 1001 is provided on the limiting frame 10, and the reset member 6 is sleeved on the guide post 1001 to prevent the reset member 6 from coming off. Setting the first driving member 3 as a solenoid valve can reduce costs and save installation space, making the structure more compact.

[0047] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0048] Embodiment 3

[0049] As Figures 1-7 shown, on the basis of Embodiment 1 or Embodiment 2, Embodiment 1 or Embodiment 2 is further limited. The difference lies in that:

[0050] It further includes a driving device 11 connected to the bracket 1, a second sensor 12 for detecting whether there is someone in the cab, and a processor 13. The first sensor 7, the second sensor 12, and the driving device 11 are all respectively signal-connected to the processor 13. The driving device 11 is used to drive the joystick 2 to rotate so as to trigger the first sensor 7. The driving device 11 includes a second driving member 1101 connected to the bracket 1, a transmission assembly connected to the driving end of the second driving member 1101, and a cam member 1102 connected to the transmission assembly. The second driving member 1101 drives the cam member 1102 to rotate through the transmission assembly. When the cam member 1102 rotates, it drives the joystick 2 to rotate so as to trigger the first sensor 7. The driving device further includes a second slider 1103 slidably connected to the bracket 1; one end of the second slider 1103 abuts against the cam member 1102, and the other end abuts against the joystick 2. The second slider 1103 is respectively provided with a second limiting block 1103a and a third limiting block 1103b for preventing the second slider 1103 from detaching from the bracket 1. When the second slider 1103 extends to a set position, the second limiting block 1103a abuts against the bracket 1. When the second slider 1103 retracts to the set position, the third limiting block 1103b abuts against the bracket 1. The driving device 11 further includes at least two ring members 1104 rotatably connected to the cam member 1102. The ring members 1104 are clamped on the bracket 1, and the cam member 1102 is indirectly rotatably connected to the bracket 1 through the ring members 1104. The transmission assembly includes a worm 1105 connected to the second driving member 1101 and a worm gear 1106 connected to the cam member 1102. The worm 1105 meshes with the worm gear 1106. The driving device 11 further includes a magnetic member 1107 installed on the side of the worm gear 1106 and a third sensor 1108 installed on the bracket 1. The third sensor 1108 detects the rotation angle of the cam member 1102 by detecting the rotation angle of the magnetic member 1107.

[0051] The second sensor 12 is signal - connected to the driving device 11. When the user parks the vehicle and gets out of the car and does not shift the vehicle gear to the parking gear, the second sensor 12 detects that there is no one in the cab and transmits a signal to the processor 13. At this time, the processor 13 determines whether the operating lever 2 is in the locked state according to the signal of the first sensor 7, that is, whether the vehicle is in the parking gear. If the operating lever 2 is not in the locked state, the driving device 11 is commanded to drive, driving the operating lever 2 to rotate to a set position and triggering the first sensor 7, and then triggering the first driving member 3 to lock the operating lever 2, and then switching the vehicle to the parking gear to ensure parking safety. The second driving member 1101 is a rotary driving member, preferably a motor. The second driving member 1101 drives the cam member 1102 to rotate through a transmission assembly. When the cam member 1102 rotates, it pushes or drives the operating lever 2 to rotate, so that the operating lever 2 rotates to the set position and triggers the first sensor 7. The second slider 1103 is arranged for transmission, so that one end of the cam member 1102 abuts against the second slider 1103, and the other end of the second slider 1103 abuts against the operating lever 2. The wear caused by friction is set between the cam member 1102 and the second slider 1103, reducing the maintenance cost. At the same time, the second limiting block 1103a and the third limiting block 1103b are arranged so that the second slider 1103 can be restricted on the bracket 1, which is also more convenient for installation and also prevents the second slider 1103 from moving excessively, further avoiding jamming. The ring member 1104 is clamped with the bracket 1 and is fixed relative to the bracket 1. The cam member 1102 is rotatably connected to the ring member 1104. The damage caused by the rotational friction of the cam member 1102 is controlled between the ring member 1104 and the cam member 1102, reducing the maintenance cost, improving the smoothness of the rotation of the cam member 1102, and also facilitating the installation of the cam member 1102. Among them, the ring member 1104 can be a general cylindrical ring member 1104, with a clearance fit with the cam member 1102; it can also be a bearing, with an interference fit with the cam member 1102. Specifically, the cam member 1102 includes a cam and a rod, and the rod is rotatably connected to the ring member 1104. The transmission assembly using the worm gear 1106 and the worm 1105 can ensure the transmission stability, and the worm gear 1106 and the worm 1105 also have a self - locking function, with better use effects.
