Description

Technical Field

[0001] This utility model belongs to the field of lock technology and relates to an electric integrated lock. Background Technology

[0002] The most common lock body structures on the market are double-fast double-action lock bodies and mechanical lock bodies;

[0003] Double-fast and double-active lock body: "Double-fast" means that both the inner and outer handles can be lifted upwards to quickly lock the door and pressed downwards to quickly open the door; "double-active" means that both the inner and outer handles can be pressed downwards to open the door. For example, in an emergency, it can open or lock the door more quickly, improving efficiency.

[0004] Mechanical lock body: It mainly relies on mechanical structure to achieve basic locking and unlocking functions. It usually completes the unlocking action by rotating a square shaft (partially rotating the lock cylinder) through an external motor, which is relatively simple and direct.

[0005] Double-fast, double-active lock bodies offer greater convenience, while mechanical lock bodies maintain the simplicity and reliability of traditional locks. Currently, there is a lack of lock body structures that can combine the functions of both double-fast, double-active lock bodies and mechanical lock bodies, and allow users to selectively switch between the two based on their needs. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems with existing lock body structures by proposing a lock body structure that combines the functions of a double-fast double-active lock body and a mechanical lock body, and allows users to selectively switch between using either the double-fast double-active lock body or the mechanical lock body according to their needs.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An electric integrated lock includes a lock panel and a main lock assembly, two side lock assemblies, and an electric control assembly mounted on the lock panel. The two side lock assemblies are respectively located on the upper and lower sides of the main lock assembly.

[0009] The main lock assembly includes a main lock box and a main lock tongue, a main latch, a rack, and a gear 1 coaxially arranged with the lock cylinder. A gear pair 1 is provided between the gear 1 and the rack. When the lock cylinder rotates, it can drive the gear 1 to drive the rack to move through the gear pair 1. A transmission component 1 is provided between the rack and the main lock tongue. When the rack moves, it can drive the main lock tongue to move through the transmission component 1.

[0010] The main lock assembly is characterized by further comprising a rotating shaft coaxially arranged with the handle, and three paddles (a first, a second, and a third) sleeved on the rotating shaft and coaxially arranged with the rotating shaft. When the handle is rotated, the rotating shaft can drive paddles (a first and a third) to rotate. Paddle (a second) is detachably fixed to paddle (a first) by a fastener. Paddle (a third) is provided with a protrusion. When paddle (a third) rotates, the protrusion can push the main latch to move horizontally.

[0011] The main lock box is equipped with a rotating plate, which is connected to the second lever and the rack and pinion respectively. When the fastener is installed, rotating the handle causes the first lever to rotate the second lever, which in turn drives the rotating plate to rotate through the first pin. The rotating plate then drives the rack and pinion to move through the second pin. After the fastener is removed, rotating the handle causes the second lever and the rotating plate to remain stationary relative to the pivot, thus keeping the main lock tongue stationary.

[0012] In the aforementioned electric interlocking lock, the rotating plate is provided with guide groove 1 and guide groove 2, a pin 1 is fixed on the lever 2, and a pin 2 is fixed on the rack. Pin 1 is inserted into guide groove 1, and pin 2 is inserted into guide groove 2.

[0013] In the aforementioned type of electric interlocking lock, the fastener is a screw.

[0014] In the aforementioned electric interlocking lock, the gear pair includes gear two and gear three rotatably disposed within the main lock housing. Gear two is a double-row gear with a coaxial gear ring one and gear ring two. Gear one meshes with gear ring one, gear ring two meshes with gear three, and gear three meshes with the aforementioned rack. When the lock cylinder rotates, it can drive gear one to drive the transmission, gear one drives gear two to rotate, gear two drives gear three to rotate, and gear three drives the rack to translate.

[0015] In the aforementioned electric interlocking lock, the transmission assembly includes a gear four rotatably disposed within the main lock housing and a push plate coaxially disposed with the gear four. The gear four meshes with a rack. An arc groove is provided on the push plate, and a protrusion is fixed on the gear four. The protrusion is inserted into the arc groove. A locking block is also fixed on the push plate, and a locking groove is provided on the main lock tongue. The locking block is inserted into the locking groove. When the rack moves horizontally, it can drive the gear four to rotate. The gear four drives the push plate to rotate through the protrusion, and the push plate pushes the main lock tongue to move horizontally through the locking block.

[0016] In the aforementioned electric interlocking lock, when the rack moves backward to reset, it drives the fourth gear to synchronously reverse to reset. The protrusion rotates along the arc groove. During the partial stroke of the rack's reverse reset, the push plate can remain stationary relative to the fourth gear so that the main lock tongue remains stationary, forming a false position.

[0017] In the aforementioned type of electric interlocking lock, the rotating plate is rotatably mounted on the main lock box via a central shaft. The center distance between the central shaft and the first pin is set as L1, and the center distance between the central shaft and the second pin is set as L2, where L2 > L1. According to the principle of motion, the farther an object is from the center of a circle, the greater the distance it travels when moving at the same angle. The purpose of this design is to amplify the rack displacement and overcome the spatial limitations.

[0018] In the aforementioned electric interlocking lock, a torsion spring is also provided between the main lock box and the main latch, which is used to push out the main latch.

[0019] In the aforementioned electric interlocking lock, the side lock assembly includes a secondary lock box, a hook tongue and a secondary inclined tongue disposed on the secondary lock box, and rack one and rack two slidably disposed on the secondary lock box. A gear pair two is also provided between rack one and rack two, so that rack one can drive rack two to move when it translates. A transmission component two is provided between the secondary inclined tongue and rack two, so that rack two can drive the secondary inclined tongue to move when it translates. A transmission component three is provided between the hook tongue and rack two, so that rack two can drive the hook tongue to move when it translates.

[0020] In the aforementioned electric interlocking lock, the gear pair two includes a first gear and a second gear rotatably mounted on the secondary lock box and coaxially arranged. The first gear meshes with a rack, and the second gear meshes with a rack. When the rack moves, it can drive the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the rack to move.

[0021] In the aforementioned electric interlocking lock, the transmission assembly two includes a transmission plate rotatably mounted on the secondary lock box, a pin fixed on the rack two, a slide groove on the transmission plate, and a pin fixed on the secondary inclined tongue. The pin two is inserted into the slide groove one. When the rack two moves, the pin one moves to abut against the transmission plate and pushes the transmission plate to rotate. The transmission plate drives the secondary inclined tongue to move through the pin two.

[0022] In the aforementioned electric interlocking lock, the transmission component three includes a pin three fixed on the rack two and a slide groove two opened on the hook tongue. The pin three is inserted into the slide groove two, and the hook tongue is rotatably disposed in the secondary lock box. When the rack two moves, it can drive the hook tongue to rotate through the pin three.

[0023] In the aforementioned electric interlocking lock, a plurality of limiting blocks are fixed on the first gear, and a limiting arc groove corresponding to the position of the limiting blocks is opened on the second gear. The limiting blocks are inserted into the limiting arc groove. When the rack moves in the reverse direction to reset, it drives the first gear to synchronously reverse and reset. The limiting blocks rotate along the limiting arc groove. During the partial stroke of the rack's reverse reset, the second gear can remain stationary relative to the first gear so that the hook tongue remains stationary and forms a false position.

[0024] In the aforementioned type of electric interlocking lock, the pitch circle diameter of the first gear is smaller than that of the second gear. The purpose of this design is to allow the second gear to travel a greater distance, thus overcoming the limitation on output distance caused by space constraints.

[0025] In the aforementioned electric interlocking lock, the rack in the main lock assembly is connected to the racks in the two side lock assemblies via two pull rods, and the rack can drive the two racks to move when it moves.

[0026] In the aforementioned electric interlocking lock, the electronic control component includes a mounting box and two drive motors, a drive rack, and a transmission gear disposed within the mounting box. A gear pair three is provided between the drive motors and the transmission gear. The two drive motors are respectively connected to the transmission gear through the gear pair three. The two drive motors work together to provide power to the transmission gear to drive the transmission gear to rotate. A gear pair four is provided between the transmission gear and the drive rack. The transmission gear drives the drive rack to translate through the gear pair four.

[0027] In the aforementioned electric interlocking lock, the gear pair three includes a cylindrical gear one, a cylindrical gear two, and a face gear. The cylindrical gear one is fixedly connected to the output shaft of the drive motor, the cylindrical gear two is coaxially fixedly connected to the face gear, the cylindrical gear one meshes with the face gear, and the cylindrical gear two meshes with the aforementioned transmission gear.

[0028] In the aforementioned electric interlocking lock, the axis of the cylindrical gear is perpendicular to the axis of the face gear.

[0029] In the aforementioned type of electric interlocking lock, two drive motors are arranged in parallel intervals and symmetrically relative to the transmission gears, and two sets of gear pairs are arranged symmetrically relative to the transmission gears.

[0030] In the aforementioned electric interlocking lock, the gear pair four includes a large gear one, a large gear two, a large gear three, a small gear one, a small gear two, and a small gear three. The small gear one is coaxially fixed to the large gear, the small gear two is coaxially fixed to the aforementioned transmission gear, the small gear three is coaxially fixed to the large gear two, the large gear one meshes with the small gear two, the small gear one meshes with the large gear two, the small gear three meshes with the large gear three, and the large gear three meshes with the aforementioned drive rack.

[0031] In the aforementioned electric interlocking lock, the electronic control component further includes a detection device for detecting the movement position of the drive rack.

[0032] In the aforementioned electric interlocking lock, the detection device includes a Hall sensor and a magnet. The Hall sensor is fixed inside the mounting box, and the magnet is fixed on the drive rack, which drives the magnet to move horizontally.

[0033] In the aforementioned electric interlocking lock, the mounting box is provided with a locking position, an unlocking position, and a stopping position. After the drive motor is powered on, it drives the drive rack and magnet to move horizontally. When the magnet moves to the locking position, unlocking position, and stopping position respectively, the motor is powered off to stop the rack and magnet from moving.

[0034] In the aforementioned electric interlocking lock, the drive rack is fixedly connected to a mounting plate, and the magnet is fixedly mounted on the mounting plate.

[0035] In the aforementioned electric interlocking lock, the mounting plate is fixedly connected to the pull rod, and when the rack is driven to move, it can drive the rack in the main lock assembly and the racks in the two side lock assemblies to move as well.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. When the fastener is installed, rotating the handle causes the first lever to rotate the second lever, which in turn rotates the rotating plate via the first pin. The rotating plate then moves the rack via the second pin, resulting in a double-fast, double-active lock body. After removing the fastener, rotating the handle only moves the main bolt. The second lever and the rotating plate remain stationary relative to the pivot, keeping the main bolt stationary. This results in a mechanical lock body. This invention allows for quick switching between a double-fast, double-active lock body and a mechanical lock body by simply removing and installing screws.

[0038] 2. There is a play between gear four and the push plate. When the rack returns to its original position, it drives gear four to rotate. Within a reasonable travel range, gear four can keep the push plate stationary and the main bolt stationary. By adding a play design to the lock body, when the door is ajar, the main bolt does not work, only the latch bolt is active. At this time, the door can be opened directly by the handle without complicated operations such as keys or fingerprints, realizing the functions of quick entry and exit without keys and temporary door fixation.

[0039] 3. There is a play between the first gear and the second gear. When the rack returns to its original position, it drives the first gear to rotate. Within a reasonable travel range, the first gear can keep the second gear stationary. The rack, hook tongue, and secondary bevel tongue also remain stationary. When the main lock tongue in the main lock assembly is not working, only the bevel tongue is active. The hook tongue and secondary bevel tongue in the side lock assembly also remain stationary, just like the main lock tongue.

[0040] 4. Two drive motors, which work together on a single gear, increase output power. Compared to motors with the same output force, the overall thickness of the dual motors is smaller. The gear and the gear plate are engaged without locking, and the motor can be unlocked with a mechanical key or handle in any state. Attached Figure Description

Detailed Implementation

[0063] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0064] like Figure 1 and Figure 2 As shown, the electric integrated lock of this utility model includes a lock panel and a main lock assembly 1, two side lock assemblies 2, and an electric control assembly 3 installed on the lock panel. The two side lock assemblies 2 are respectively located on the upper and lower sides of the main lock assembly 1.

[0065] like Figures 3 to 5As shown, the main lock assembly 1 includes a main lock box 101 and a main lock tongue 102, a main latch 103, a rack 104, and a gear 105 coaxially arranged with the lock cylinder, all disposed on the main lock box 101. A gear pair is provided between the gear 105 and the rack 104. When the lock cylinder rotates, it can drive the gear 105 to drive the rack 104 to translate through the gear pair. A transmission assembly is provided between the rack 104 and the main lock tongue 102. When the rack 104 translates, it can drive the main lock tongue 102 to translate through the transmission assembly.

[0066] like Figure 9 and Figure 10 As shown, the main lock assembly 1 also includes a rotating shaft 106 coaxially arranged with the handle, and three paddles 107, 108, and 109 sleeved on the rotating shaft 106 and coaxially arranged with the rotating shaft 106. When the handle is rotated, the rotating shaft 106 can drive the paddles 107 and 109 to rotate. The paddle 108 is detachably fixed to the paddle 107 by a fastener 110. The paddle 109 is provided with a protrusion 116. When the paddle 109 rotates, the protrusion 116 can push the main latch 103 to move horizontally. A torsion spring 128 is also provided between the main lock box 101 and the main latch 103. The torsion spring 128 is used to push the main latch 103 out.

[0067] like Figure 13 As shown, a rotating plate 111 is rotatably mounted inside the main lock box 101. The rotating plate 111 has a first guide groove 112 and a second guide groove 113. A first pin 114 is fixed to a second lever 108, and a second pin 115 is fixed to a rack 104. The first pin 114 is inserted into the first guide groove 112, and the second pin 115 is inserted into the second guide groove 113. When the fastener 110 is installed, rotating the handle causes the first lever 107 to rotate the second lever 108. The second lever 108, through the first pin 114, drives the rotating plate 111 to rotate, and the rotating plate 111, through the second pin 115, drives the rack 104 to translate. After removing the fastener 110, rotating the handle causes the second lever 108 and the rotating plate 111 to remain stationary relative to the pivot 106, thus keeping the main lock tongue 102 stationary. The fastener 110 is a screw.

[0068] like Figure 13 As shown, the rotating plate 111 is rotatably mounted on the main lock box 101 via a central shaft 127. The center distance between the central shaft 127 and the first pin 114 is set as L1, and the center distance between the central shaft 127 and the second pin 115 is set as L2, where L2 > L1. According to the principle of motion, the farther an object is from the center of a circle, the greater the distance it travels when moving at the same angle. The purpose of this design is to amplify the displacement of the rack 104 and overcome the spatial limitations.

[0069] like Figures 6 to 8As shown, the gear pair includes a second gear 117 and a third gear 118 rotatably disposed within the main lock box 101. The second gear 117 is a double-row gear with a coaxial gear ring 119 and a gear ring 120. The first gear 105 meshes with the gear ring 119, the gear ring 120 meshes with the gear ring 118, and the gear ring 118 meshes with the rack 104. When the lock cylinder rotates, it can drive the first gear 105 to drive the gear 105 to rotate, the first gear 105 drives the second gear 117 to rotate, the second gear 117 drives the third gear 118 to rotate, and the third gear 118 drives the rack 104 to translate.

[0070] like Figure 11 As shown, the transmission assembly includes a gear 121 rotatably disposed within the main lock box 101 and a push plate 122 coaxially disposed with the gear 121. The gear 121 meshes with a rack 104. An arc groove 123 is provided on the push plate 122. A protrusion 124 is fixedly disposed on the gear 121 and inserted into the arc groove 123. A locking block 125 is also fixedly disposed on the push plate 122. A locking groove 126 is provided on the main lock tongue 102 and the locking block 125 is inserted into the locking groove 126. When the rack 104 translates, it can drive the gear 121 to rotate. The gear 121 drives the push plate 122 to rotate through the protrusion 124. The push plate 122 pushes the main lock tongue 102 to translate through the locking block 125.

[0071] like Figure 12 As shown, when the rack 104 reverses and resets, it drives the gear 4 121 to synchronously reverse and reset. The protrusion 124 rotates along the arc groove 123. During the partial stroke of the rack 104 reversing and resetting, the push plate 122 can remain stationary relative to the gear 4 121 so that the main locking tongue 102 remains stationary and forms a false position.

[0072] like Figure 14 and Figure 15 As shown, the side lock assembly 2 includes a secondary lock box 201, a hook tongue 202 and a secondary oblique tongue 203 disposed on the secondary lock box 201, and a rack 1 204 and a rack 205 slidably disposed on the secondary lock box 201. A gear pair 2 is also provided between the rack 1 204 and the rack 205. When the rack 1 204 translates, it can drive the rack 205 to translate through the gear pair 2. A transmission assembly 2 is provided between the secondary oblique tongue 203 and the rack 205. When the rack 205 translates, it can drive the secondary oblique tongue 203 to move through the transmission assembly 2. A transmission assembly 3 is provided between the hook tongue 202 and the rack 205. When the rack 205 translates, it can drive the hook tongue 202 to move through the transmission assembly 3.

[0073] like Figure 16 and Figure 17As shown, the second gear pair includes a first gear 206 and a second gear 207 rotatably mounted on the secondary lock box 201 and coaxially arranged. The first gear 206 meshes with a rack 204, and the second gear 207 meshes with a rack 205. When the rack 204 translates, it can drive the first gear 206 to rotate, the first gear 206 drives the second gear 207 to rotate, and the second gear 207 drives the rack 205 to translate. The second transmission assembly includes a transmission plate 208 rotatably mounted on the secondary lock box 201, a first pin 209 fixed on the second rack 205, a first groove 210 formed on the transmission plate 208, and a second pin 211 fixed on the secondary inclined tongue 203. The second pin 211 is inserted into the first groove 210. When the second rack 205 translates, the first pin 209 moves to abut against the transmission plate 208 and pushes the transmission plate 208 to rotate. The transmission plate 208 drives the secondary inclined tongue 203 to translate via the second pin 211. The third transmission assembly includes a third pin 212 fixed on the second rack 205 and a second groove formed on the hook tongue 202. The third pin 212 is inserted into the second groove. The hook tongue 202 is rotatably mounted in the secondary lock box 201. When the second rack 205 translates, it can drive the hook tongue 202 to rotate via the third pin 212.

[0074] like Figure 18 As shown, the first gear 206 is fixed with several limiting blocks 215, and the second gear 207 has limiting arc grooves 216 corresponding to the positions of the limiting blocks 215. The limiting blocks 215 are inserted into the limiting arc grooves 216. When the rack 204 reverses and resets, it drives the first gear 206 to synchronously reverse and reset. The limiting blocks 215 rotate along the limiting arc grooves 216. During the partial stroke of the rack 204's reverse reset, the second gear 207 can remain stationary relative to the first gear 206 so that the hook tongue 202 remains stationary, forming a false position. The pitch circle diameter of the first gear 206 is smaller than that of the second gear 207. The purpose of this design is to allow the second gear 207 to move a greater distance, thus solving the limitation on output distance caused by space constraints.

[0075] like Figure 19 As shown, the electronic control component 3 includes a mounting box 301 and two drive motors 302, a drive rack 303, and a transmission gear 304 disposed within the mounting box 301. A gear pair 3 is provided between the drive motors 302 and the transmission gear 304. The two drive motors 302 are respectively connected to the transmission gear 304 via the gear pair 3. The two drive motors 302 work together to provide power to the transmission gear 304 to drive its rotation. A gear pair 4 is provided between the transmission gear 304 and the drive rack 303, through which the transmission gear 304 drives the drive rack 303 to translate. Figure 21As shown, the two drive motors 302 are arranged in parallel and symmetrically relative to the transmission gear 304, and the two sets of gear pairs are symmetrically arranged relative to the transmission gear 304.

[0076] like Figure 20 As shown, the gear pair three includes a first cylindrical gear 305, a second cylindrical gear 306, and a face gear 307. The first cylindrical gear 305 is fixedly connected to the output shaft of the drive motor 302. The second cylindrical gear 306 is coaxially fixedly connected to the face gear 307. The first cylindrical gear 305 meshes with the face gear 307, and the second cylindrical gear 306 meshes with the aforementioned transmission gear 304. The axis of the first cylindrical gear 305 is perpendicular to the axis of the face gear 307. The gear pair four includes a large gear 308, a large gear 309, a large gear 310, a small gear 311, a small gear 312, and a small gear 313. The small gear 311 is coaxially fixed to the large gear 308, the small gear 312 is coaxially fixed to the aforementioned transmission gear 304, and the small gear 313 is coaxially fixed to the large gear 309.
