Description

Technical Field

[0001] This utility model relates to the field of machine cover lock technology, specifically to a self-priming and self-opening machine cover lock. Background Technology

[0002] Traditional self-closing and self-opening machine cover locks typically only have one-way manual opening and closing functions, and lack an effective anti-pinch protection mechanism. During the cover closing process, if a foreign object (such as a human finger or other object) becomes stuck in the closing area, the traditional lock body cannot detect the obstacle in time and stop the action, easily causing pinching injuries or equipment damage, posing a significant safety hazard. Therefore, those skilled in the art have provided self-closing and self-opening machine cover locks to solve the problems mentioned in the background art. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a self-priming and self-opening cover lock. The cover lock includes a housing, and a switch base is installed at the bottom of the housing. Micro switch one, micro switch two, and micro switch three are respectively embedded in the switch base.

[0004] The housing also includes an emergency opening mechanism, a pawl mechanism, a force-relieving mechanism, a ratchet mechanism, an ejection mechanism, a self-priming mechanism, and a self-priming linkage mechanism. The ratchet mechanism and the ejection mechanism are coaxially mounted, and one end of the self-priming linkage mechanism is connected to the self-priming mechanism.

[0005] Before the cover is locked, the actuator drives the self-priming mechanism to rotate and engages the self-priming linkage mechanism with the ejection mechanism so that it engages with the unloading mechanism. When the ejection mechanism touches the micro switch one, the actuator is reset and the unloading is completed.

[0006] If the ejection mechanism and the unloading mechanism are engaged to a semi-locked state, the electric strut will drive the door mechanism to push the ratchet mechanism to rotate around the ratchet axis and engage with the pawl mechanism. The ratchet will stop when it touches the micro switch two, and the semi-locked state will be achieved.

[0007] When the ratchet mechanism touches the micro switch two, it sends a signal, and the actuator drives the self-priming mechanism to rotate and engages the self-priming linkage mechanism, which in turn drives the ratchet mechanism to rotate around the ratchet axis and engage with the pawl mechanism, thus locking the entire mechanism.

[0008] If the ejection mechanism and the unloading mechanism cannot engage to the semi-locked state, it is determined that there is an obstacle in the hood area. The electric strut will prevent the door mechanism from smoothly pushing the ratchet mechanism to rotate around the ratchet axis and engage with the pawl mechanism in the semi-locked state. The electric strut will then perform an opening action to achieve anti-pinch.

[0009] Preferably, when the self-priming linkage mechanism and the ratchet mechanism are locked, the emergency opening mechanism is pulled to open the self-priming linkage mechanism and release the ratchet mechanism.

[0010] Preferably, the housing consists of an upper cover, a lower cover, and a decorative cover. The upper cover and the lower cover are fixed together by riveting, and the decorative cover, which is located on the top of the upper cover and the lower cover, is fixed to the upper cover by screws.

[0011] Preferably, the ratchet mechanism includes a ratchet insert, the outside of which is coated with plastic, and the inside of which is a ratchet shaft with an ejection mechanism mounted on the ratchet shaft.

[0012] The ejection mechanism includes an ejection insert. The ejection insert has an ejection plastic coating at one end near the unloading mechanism. The ejection insert is sleeved on the ratchet shaft. An ejection spring is sleeved on the ratchet shaft and connected to the ejection insert.

[0013] Preferably, the self-priming mechanism includes a self-priming rocker arm insert, the outside of which is wrapped with a layer of self-priming rocker arm plastic coating, a self-priming rocker arm shaft is provided inside the self-priming rocker arm insert, a self-priming rocker arm return spring is provided on the self-priming rocker arm shaft, and the self-priming mechanism is connected to the self-priming linkage mechanism.

[0014] Preferably, the self-priming linkage mechanism includes a self-priming linkage arm insert, a self-priming linkage shaft is provided at the bottom of the self-priming linkage arm insert, the self-priming linkage shaft is installed in the self-priming rocker arm insert, and a self-priming linkage return spring is sleeved on the self-priming linkage shaft. The top of the self-priming linkage arm insert is provided with a self-priming linkage arm plastic wrap, and a cooperating shaft is provided on the side wall of the self-priming linkage arm plastic wrap.

[0015] Preferably, the pawl mechanism includes a pawl insert, the outer side of which is provided with pawl plastic coating, and the pawl insert is provided with a pawl shaft inside. A pawl spring is provided on the side of the pawl insert near the lower cover, and a pawl signal paddle spring and a pawl signal paddle are provided on the side of the pawl insert near the upper cover and sleeved on the pawl shaft.

[0016] Preferably, the unloading mechanism includes an unloading pawl, an unloading pawl shaft, and an unloading pawl spring. The unloading pawl is mounted on the unloading pawl shaft, and an unloading pawl spring is provided between the unloading pawl shaft and the unloading pawl. The top of the unloading pawl is provided with an arc-shaped U-shaped groove, which is sleeved on the pawl shaft. The side wall of the unloading pawl is provided with a groove.

[0017] Preferably, the emergency opening mechanism includes an opening rocker arm insert, a connector, and an emergency release rocker arm. The opening rocker arm insert is sleeved on the opening rocker arm rotation shaft, and the opening rocker arm rotation shaft is also provided with an opening rocker arm return spring connected to the opening rocker arm insert. The bottom of the opening rocker arm insert is provided with an opening rocker arm plastic coating. The opening rocker arm plastic coating is connected to the connector by a pull wire. The opening rocker arm insert is connected to the emergency release rocker arm through the emergency release rocker arm shaft. The upper part of the emergency release rocker arm is provided with an inner groove, and the emergency release rocker arm is sleeved on the self-priming rocker arm shaft through the inner groove.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] In this utility model, the linkage design of micro switch one and ejection mechanism is used to detect obstacles in the closed section in real time. The self-priming linkage mechanism drives the ejection mechanism to rotate. When the ejection mechanism can trigger micro switch one, the unloading process is completed. There are no obstacles during the closing of the cover. Otherwise, the locking action is forcibly stopped and the cover is opened, which effectively prevents hand pinching or object damage and significantly improves safety.

[0020] In this utility model, the emergency opening mechanism is linked to the emergency release rocker arm by a pull wire. When the self-priming linkage mechanism and the ratchet mechanism are locked, the joint can be manually pulled to open the plastic wrapping of the self-priming linkage arm and quickly release the ratchet mechanism, solving the unlocking needs in emergency situations. It is easy to operate and highly reliable.

[0021] In this invention, the ejection mechanism and the micro switch are separated to reduce mechanical wear and extend the service life of the switch; each mechanism is protected by plastic coating to improve overall durability.

[0022] This utility model's self-priming and self-opening cover lock can automatically open and close, identify obstacles, and has an anti-pinch function, making it safer. Attached Figure Description

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0046] Please refer to Figures 1 to 13 In this embodiment, a self-priming and self-opening cover lock is provided, such as... Figures 1-3 As shown, the cover lock includes a housing, which consists of an upper cover 1, a lower cover 2, and a decorative cover 3. The upper cover 1 and the lower cover 2 are fixed together by riveting. The decorative cover 3, which is set on the top of the upper cover 1 and the lower cover 2, is fixed to the upper cover 1 by screws. The three together form the outer housing, which realizes the installation and protection of its internal structural components.

[0047] like Figure 3 as well as Figure 6 As shown, a switch base 5 is installed at the bottom of the housing. The bottom of the switch base 5 is connected to the wiring harness assembly 6 for easy wiring. Microswitches 1 51, 2 52 and 3 53 are embedded in the switch base 5. Different switches correspond to different structures, which will be described in detail below.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, the housing is equipped with an emergency opening mechanism 4, a pawl mechanism 7, a force-relieving mechanism 8, a ratchet mechanism 9, an ejection mechanism 10, a self-priming mechanism 11, and a self-priming linkage mechanism 12.

[0049] Among them, the ratchet mechanism 9 and the ejection mechanism 10 are coaxially installed, the pawl mechanism 7 is located on one side of the ratchet mechanism 9, and the two are locked when they are linked and engaged; otherwise, the cover lock is in the open state. The pawl mechanism 7 is on the same side as the unloading mechanism 8, and one end of the self-priming linkage mechanism 12 is connected to the self-priming mechanism 11.

[0050] The ejection mechanism 10, in conjunction with its ejection spring 103, can lift the car hood to a certain height. Before the hood lock body performs electric engagement, there is a force-relieving process, that is, unloading the ejection force, so that the electric support rod can drive the hood smoothly and evenly into the half-lock state of the lock body through the door mechanism. Figure 12 , Figure 11 The diagram shows the door fully open. (It should be noted that the door mechanism is a structural component installed on the car to drive the ratchet mechanism 9 and other structural parts. It is existing technology and, like the electric strut, is independent of the lock body and serves as an external power source.)

[0051] When the car hood receives an automatic door closing command, the actuator works, pulling the self-closing mechanism 11 on the lock body to rotate. The rotation of the self-closing mechanism 11 will drive the cooperating shaft 123 on the self-closing linkage mechanism 12 to engage with the ejection mechanism 10, and push the ejection mechanism 10 to rotate. The ejection mechanism 10 rotates until the trigger signal micro switch 51 stops. At this time, the actuator resets, and the self-closing mechanism 11 and the self-closing linkage mechanism 12 return to their original positions. At this time, the ejection mechanism 10 is mechanically engaged with the unloading pawl 81 in the cooperating mechanism 8 in the half-lock position. This process is the unloading logic.

[0052] If the hood closes without encountering any obstacles during this process, the electric strut, through the action of the door mechanism, smoothly pushes the ratchet mechanism 9 to the half-lock position, triggering the signal microswitch 52 to stop. The electric strut stops working, and at this time, the ratchet mechanism 9 and the pawl mechanism 7 are mechanically engaged in the half-lock position. Figure 12 As shown;

[0053] If an obstacle is encountered during this process, the ejection mechanism 10 and the cooperating mechanism 8 will not be able to mechanically engage to the half-lock position during the unloading logic process. As a result, the electric strut will stop the closing action through the door mechanism and perform the opening action to achieve the anti-pinch function.

[0054] When the ratchet mechanism 9 and the pawl mechanism 7 are mechanically engaged in a half-lock position, the signal of micro switch 52 is triggered, the actuator works, pulls the self-closing mechanism 11 on the lock body to rotate, drives the self-closing linkage arm insert 121 in the self-closing linkage mechanism 12 to engage with the ratchet insert 91 in the ratchet mechanism 9, and pushes the ratchet mechanism 9 to rotate, so that the ratchet mechanism 9 and the pawl mechanism 7 are fully mechanically engaged to the full-lock position, as shown in Figure 13. At the same time, the pawl signal paddle 75 in the pawl mechanism 7 triggers the signal micro switch 53, and the actuator stops and resets.

[0055] During the locking process, the mutual linkage between the self-priming linkage mechanism 12 and the ejection mechanism 10, as well as the ejection mechanism 10 and the unloading mechanism 8, plays a role in preventing pinching. Moreover, the ejection mechanism 10 and the micro switch 51 are designed separately, which can extend the service life of the switch. At the same time, through the interaction between the self-priming mechanism 11 and the self-priming linkage mechanism 12 and the ejection mechanism 10, the two functions of unloading and self-priming can be realized.

[0056] Moreover, during this process, the engagement of the ejection mechanism 10 and the unloading mechanism 8 not only achieves the anti-pinch function of the lock body, but also enables the switching between high and low configurations of single and double locks;

[0057] When the self-priming linkage mechanism 12 and the ratchet mechanism 9 are locked, the emergency opening mechanism 4 can be pulled, which will open the self-priming linkage mechanism 12, thereby allowing the ratchet mechanism 9 to work normally, acting as an emergency switch and achieving emergency disengagement. Figure 9 As shown;

[0058] like Figure 7 , Figure 8 As shown, the ratchet mechanism 9 includes a ratchet insert 91, and a ratchet coating 92 is provided on the outside of the ratchet insert 91. The ratchet coating 92 is used to protect the ratchet insert 91 and play a role in wear resistance and protection. A ratchet shaft 93 is provided inside the ratchet insert 91. An ejection mechanism 10 is installed on the ratchet shaft 93. The ejection mechanism 10 includes an ejection insert 101. An ejection coating 102 is provided at one end of the ejection insert 101 near the unloading mechanism 8. At the same time, the ejection insert 101 is sleeved on the ratchet shaft 93. An ejection spring 103 is sleeved on the ratchet shaft 93. The ejection spring 103 is connected to the ejection insert 101 and rotates around the ratchet shaft 93.

[0059] The self-priming mechanism 11 includes a self-priming rocker arm insert 111. The outside of the self-priming rocker arm insert 111 is wrapped with a layer of self-priming rocker arm plastic coating 112. The self-priming rocker arm insert 111 is provided with a self-priming rocker arm shaft 113. The self-priming rocker arm shaft 113 is provided with a self-priming rocker arm return spring 114. The self-priming rocker arm return spring 114 realizes the self-priming rocker arm insert 111 returning to its original state.

[0060] The self-priming mechanism 11 is connected to the self-priming linkage mechanism 12. The self-priming linkage mechanism 12 includes a self-priming linkage arm insert 121. The bottom of the self-priming linkage arm insert 121 is provided with a self-priming linkage shaft 124. The self-priming linkage shaft 124 is installed in the self-priming rocker arm insert 111, and a self-priming linkage return spring 125 is sleeved on the self-priming linkage shaft 124. By relying on the action of the self-priming linkage return spring 125 and the self-priming linkage shaft 124, the self-priming linkage arm insert 121 can return to its original position.

[0061] The top of the self-priming linkage arm insert 121 is provided with a self-priming linkage arm plastic cover 122, and the side wall of the self-priming linkage arm plastic cover 122 is provided with a cooperating shaft 123. The actuator drives the self-priming rocker arm insert 111 to move, which causes the self-priming linkage arm insert 121 to rotate together through the self-priming linkage shaft 124, so that the self-priming linkage arm plastic cover 122 on its top also rotates together. The cooperating shaft 123 on the self-priming linkage arm plastic cover 122 moves and engages with the ejector insert 101, thereby driving the ejector mechanism 10 to rotate and engage with the unloading mechanism 8. If the ejector plastic cover 102 can contact the micro switch 51, it means that there is no obstacle in the unloading process and a half-lock state can be achieved, and the car hood can be closed normally. Conversely, if there is an obstacle, the ejector plastic cover 102 cannot contact the micro switch 51, that is, the unloading process cannot be achieved. The electric support rod opens the hood in the direction of the hood to achieve the anti-pinch function in the hood closing process.

[0062] like Figure 6 As shown, the pawl mechanism 7 includes a pawl insert 71, a pawl-coated plastic 72 on the outside of the pawl insert 71, and a pawl shaft 73 inside the pawl insert 71. A pawl spring 76 is provided on the side of the pawl insert 71 near the lower cover 2. The pawl spring 76 is used to realize the return of the pawl insert 71. On the side of the pawl insert 71 near the upper cover 1, there is a pawl signal paddle spring 74 and a pawl signal paddle 75. Both the pawl signal paddle spring 74 and the pawl signal paddle 75 are sleeved on the pawl shaft 73. The pawl shaft 73 limits the unloading mechanism 8. During the rotation of the pawl shaft 73, it will drive the pawl signal paddle 75 to move together. Then the pawl signal paddle 75 will interact with the micro switch 53 to realize signal transmission. The signal is sent to the actuator, thereby operating the pawl mechanism 7.

[0063] The unloading mechanism 8 includes an unloading pawl 81, an unloading pawl shaft 82, and an unloading pawl spring 83. The unloading pawl 81 is mounted on the unloading pawl shaft 82, and an unloading pawl spring 83 is provided between the unloading pawl shaft 82 and the unloading pawl 81. The top of the unloading pawl 81 is provided with an arc-shaped U-shaped groove, which is sleeved on the pawl shaft 83 to limit the movement of the unloading pawl 81. The side wall of the unloading pawl 81 is provided with a groove, which can engage with the ejector insert 101 in the ejector mechanism 10.

[0064] In this application, as Figure 4 and Figure 6As shown, the emergency opening mechanism 4 is used as an emergency switch. It includes an opening rocker arm insert 41, a connector 44, and an emergency release rocker arm 48. The opening rocker arm insert 41 is sleeved on the opening rocker arm rotation shaft 45, and the opening rocker arm rotation shaft 45 is also provided with an opening rocker arm return spring 46 connected to the opening rocker arm insert 41. The opening rocker arm return spring 46 drives the opening rocker arm insert 41 to return to its original position after the opening rocker arm insert 41 rotates. The bottom of the opening rocker arm insert 41 is provided with an opening rocker arm plastic coating 42. The opening rocker arm plastic coating 42 is connected to the connector 44 by a pull wire 43. Pulling the connector 44, the opening rocker arm insert 41, which is fixed together with the opening rocker arm plastic coating 42, can rotate through the action of the pull wire 43.

[0065] Then, the opening rocker arm insert 41 is connected to the emergency release rocker arm 48 through the emergency release rocker arm shaft 47. The upper part of the emergency release rocker arm 48 has an inner groove. The emergency release rocker arm 48 is sleeved on the self-priming rocker arm shaft 113 through the inner groove. When the self-priming linkage arm plastic wrap 122 and the ratchet insert 91 are jammed, the opening rocker arm insert 41 is rotated by pulling the connector 44 under the action of the pull wire 43, which in turn drives the emergency release rocker arm 48 to move. The emergency release rocker arm 48 will push open the self-priming linkage arm plastic wrap 122, so that the ratchet insert 91, that is, the ratchet mechanism 9, is released and can move again.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
