Description

Technical Field

[0001] This utility model relates to the field of electric lock technology, specifically to an electric seat pad lock that is easy to install. Background Technology

[0002] Electric vehicles have become an important means of transportation in people's daily lives. Due to their size and weight limitations, electric vehicles or motorcycles are difficult to carry around, so people need to store them at office buildings or temporary parking areas in residential areas. However, theft of the entire vehicle or battery frequently occurs, causing property losses to users. Therefore, improving anti-theft features is increasingly important. As a means of anti-theft, electric locks are now commonly installed on electric vehicles. The function of electric locks is to lock the electric vehicle after it is parked to prevent theft.

[0003] An existing type of electronic lock, such as Figure 6 As shown, the lock includes a self-locking module and a motor module 02 mounted on a lock plate 01. The self-locking module includes a locking block 03 and an unlocking block 04. The locking block is connected to the seat pad lock plate and the unlocking block via elastic elements. The motor module 02 is fixed to the back of the lock plate 01 by multiple screws and has a rotating block that cooperates with the unlocking block. The automatic unlocking operation of the electric lock is achieved through the cooperation of the unlocking block and the rotating block. From the structure of the electric lock described above, it can be seen that using multiple screws to fix the motor module increases assembly time and labor intensity. The installation involves many parts, making the entire installation process cumbersome and inefficient. Furthermore, in environments with vibration, the screws may gradually loosen due to mechanical stress, which can cause the motor module to shift or wobble, reducing the overall reliability of the lock. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the problems of increased assembly time and labor intensity, numerous installation parts, cumbersome and inefficient installation process, and poor installation reliability caused by using multiple screws to fix the motor module in the prior art. Therefore, this utility model provides a convenient electric control seat pad lock with a simple installation structure, reduced number of parts and assembly steps, shortened assembly time, and improved installation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a conveniently installed electric control seat lock, including a fixed plate and a drive module and a locking assembly disposed on the front and back of the fixed plate.

[0006] As a preferred embodiment, the drive housing has a mounting surface that fits and connects to the back of the fixing plate, the limiting hook is L-shaped and disposed at one end of the mounting surface, and the positioning block and locking buckle are respectively disposed at the other end of the mounting surface.

[0007] As a preferred embodiment, the locking buckle includes a main support portion integrally formed on the drive housing, and two elastic buckle portions disposed opposite to the main support portion, the two elastic buckle portions being engaged with the fixing plate through locking holes.

[0008] As a preferred embodiment, the engaging ends of the two elastic buckle parts are each provided with an arc-shaped guide slope.

[0010] As a preferred embodiment, one end of the fixing plate is provided with a limiting groove adjacent to the limiting hole, and the driving housing is provided with a limiting block that is engaged in the limiting groove. The limiting block blocks the opening of the limiting groove and forms a closed wire passage hole between them.

[0011] As a preferred embodiment, the locking assembly includes a locking buckle and a locking hook rotatably disposed on the front side of the fixed plate, and an unlocking spring disposed between the locking buckle and the locking hook. The fixed plate is provided with a locking groove. The locking buckle and the locking hook have a locking state in which they are rotatably engaged to block the locking groove, and an unlocking state in which they are rotatably disengaged to open the locking groove. The drive module has an unlocking wheel rotatably disposed on the outside of the drive housing. The unlocking wheel passes through the fixed plate and is connected to the locking buckle. The top of the unlocking wheel is provided with an unlocking rod offset from its axis. One side of the locking buckle is provided with a connecting groove that cooperates with the unlocking rod.

[0012] As a preferred embodiment, the drive assembly includes a motor, a transmission gear set, and an unlocking wheel disposed in the electrical control box. The transmission gear set includes a meshing transmission gear and a drive gear. The drive gear is coaxially linked with the unlocking wheel. The bottom of the unlocking wheel is provided with a push rod offset from its axis. The drive housing is provided with an arc guide groove for the push rod to make circumferential motion. A return spring is disposed in the arc guide groove. When the unlocking wheel drives the locking element to unlock, the push rod compresses the return spring.

[0013] As a preferred embodiment, the unlocking wheel includes an annular base covering the opening of the arc guide groove, the push rod is disposed on the annular base, the arc guide groove includes a positioning groove section for positioning and installing the return spring, and two sets of limiting bosses disposed at both ends of the positioning groove section, the two ends of the return spring are limited and abutted against the two sets of limiting bosses, and when the push rod rotates into the positioning groove section, it squeezes one end of the return spring.

[0014] As a preferred embodiment, the fixing plate is provided with a signal detection switch located on the movement path of the locking hook, and the signal detection switch is positioned close to the limiting groove so that the line connecting the signal detection switch passes through the limiting groove.

[0015] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0016] 1. In the electrically controlled seat lock provided by this utility model, the drive module and the fixed plate are reliably fixed through multiple cooperation mechanisms: specifically, a limit hook and a limit hole form a hook-and-limit mechanism at one end, allowing the limit hook to pass through the limit hole and hook onto the fixed plate in the opposite direction to resist axial tension; a positioning block and a positioning hole form a precise positioning mechanism at the other end, ensuring that the motor module is accurately positioned and does not shift; and an elastic buckle and a locking hole provide a continuous locking force. The three mechanisms work together to ensure that the drive module and the fixed plate are tightly fitted and their relative positions are stable. Furthermore, the elasticity of the elastic buckle provides a certain buffer during vibration, reducing the risk of loosening and improving the overall reliability of the lock body. The installation structure of this electrically controlled lock, through the combination design of the limit hook hooking onto the limit hole, the positioning block inserting into the positioning hole, and the locking buckle and locking hole buckle connection, eliminates the need for multiple screws. It achieves rapid positioning and fixing of the drive module and the fixed plate solely through buckles and positioning insertions, reducing the number of parts and assembly steps, significantly shortening assembly time, reducing labor intensity, and significantly improving installation efficiency.

[0017] 2. In the electrically controlled seat lock provided by this utility model, the mounting surface of the drive housing is attached to the back of the fixed plate. According to the limit hook, positioning block and locking buckle respectively set at both ends of the mounting surface, a precise positioning layout is formed. The positioning block is inserted into the positioning hole and cooperates with the limit hook to abut in the limit hole, which can quickly calibrate the relative position of the drive module and the fixed plate. The positioning block and the positioning hole form a tight-fitting positioning plug-in, and the limit hook and the limit hole form an anti-disengagement hook, which helps to eliminate assembly errors and avoid installation offset. Then, the locking buckle cooperates with the locking hole. This elastic locking buckle deforms and gets into the locking hole when pressed. After rebounding, it generates a continuous locking force, which further ensures that the drive module and the fixed plate are tightly attached, reduces gaps and improves structural stability.

[0018] 3. In the electrically controlled seat pad lock provided by this utility model, the locking buckle adopts a symmetrical structure of a main support part and two elastic buckle parts. The two elastic buckle parts are respectively engaged with the fixing plate from both sides of the locking hole, forming a bidirectional balanced locking force. This symmetrical design can avoid loosening or displacement caused by uneven force on one side of the buckle, ensuring a tighter fit between the drive module and the fixing plate, and further enhancing the overall structure's resistance to loosening under vibration. The main support part is integrally formed into the drive housing, providing stable support for the elastic buckle parts, ensuring that the buckle parts are not easily deformed during long-term use or repeated vibration, maintaining a continuous locking effect, and extending the service life of the structure.

[0019] 4. In the electrically controlled seat pad lock provided by this utility model, the connection between the drive module and the fixed plate is further enhanced by the cooperation of the limiting block and the limiting groove. It is equivalent to adding an auxiliary positioning point at one end of the fixed plate, which avoids local loosening that may be caused by the force of a single limiting hook, and enhances the stability of the installation structure. At the same time, the closed wire hole formed by the limiting groove and the limiting block provides a dedicated wire path for the wire, forcing the wire to be arranged along a fixed trajectory, ensuring that the line is neat and orderly, and avoiding the safety hazards caused by messy tangling, thus realizing the wire protection function.

[0031] Example

[0032] This embodiment provides, as follows: Figure 1-5The diagram illustrates a conveniently installed electrically controlled seat lock, comprising a fixed plate 1 and drive modules and locking components disposed on both sides of the fixed plate 1. The drive module includes a drive housing 2 and a drive component disposed on the drive housing 2. An installation structure is provided between the drive module and the fixed plate 1 to maintain their relative positions. The installation structure includes: a limiting hole 11 disposed at one end of the fixed plate 1, and a limiting hook 21 disposed on the drive housing 2 and passing through the limiting hole 11 to abut against the fixed plate 1; a positioning hole 12 disposed at the other end of the fixed plate 1, and a positioning block 22 disposed on the drive housing 2 and matched and inserted into the positioning hole 12 to form a positioning fit; and at least one locking hole 13 disposed on the fixed plate 1, and a locking buckle 23 disposed on the drive housing 2 and elastically connected to the locking hole 13.

[0033] The above-described implementation method is the core technical solution of this example. The drive module and the fixed plate 1 are reliably fixed through multiple cooperations: specifically, the limit hook 21 and the limit hole 11 form a hook-and-hold mechanism at one end, so that the limit hook 21 passes through the limit hole 11 and hooks the fixed plate 1 in the opposite direction to resist axial tension; then the positioning block 22 and the positioning hole 12 form a precise positioning mechanism at the other end to ensure that the position of the motor 41 module is accurate and does not deviate; and the elastic buckle and the locking hole 13 provide a continuous locking force. The three work together to make the drive module and the fixed plate 1 fit tightly and have a stable relative position. In addition, the elastic characteristics of the elastic buckle can also provide a certain buffer during vibration, reduce the risk of loosening, and improve the overall reliability of the lock body. This type of electrically controlled seat pad lock uses an installation structure that combines a limit hook 21 engaging with the limit hole 11, a positioning block 22 inserting into the positioning hole 12, and a locking buckle 23 engaging with the locking hole 13. This design eliminates the need for multiple screws and allows for quick positioning and fixing of the drive module and the fixing plate using only buckles and positioning plugs. This reduces the number of parts and assembly steps, significantly shortens assembly time, reduces labor intensity, and significantly improves installation efficiency.

[0034] In a further preferred configuration, the drive housing 2 has a mounting surface that fits and connects to the back of the fixing plate, the limiting hook 21 is arranged in an L-shape at one end of the mounting surface, and the positioning block 22 and the locking buckle 23 are respectively arranged at the other end of the mounting surface. In this structural configuration, the mounting surface of the drive housing 2 is attached to the back of the fixing plate 1. The limiting hook 21, positioning block 22, and locking buckle 23 are respectively positioned at both ends of the mounting surface, forming a precise positioning layout. The positioning block 22, inserted into the positioning hole 12 and engaged with the limiting hook 21 in the limiting hole 11, allows for quick calibration of the relative position of the drive module and the fixing plate. The positioning block 22 and the positioning hole 12 form a tight-fitting positioning connection, and the limiting hook 21 and the limiting hole 11 form an anti-disengagement hook, which helps eliminate assembly errors and prevent installation misalignment. Then, the locking buckle 23 engages with the locking hole 13. This elastic locking buckle deforms and engages in the locking hole 13 when pressed, and after rebounding, it generates a continuous locking force, further ensuring a tight fit between the drive module and the fixing plate, reducing gaps, and improving structural stability.

[0035] like Figure 4 As shown, the locking buckle 23 includes a main support portion integrally formed on the drive housing 2, and two elastic latching portions 231 oppositely disposed on the main support portion. The main support portion has a cylindrical structure, and the two elastic latching portions 231 are engaged with the fixing plate 1 through the locking hole 13. This locking buckle 23 adopts a symmetrical structure of the main support portion and the two elastic latching portions 231. The two elastic latching portions 231 are engaged with the fixing plate 1 from both sides of the locking hole 13, forming a bidirectional balanced locking force. This symmetrical design can avoid loosening or displacement caused by uneven force on one side of the latch, ensuring a tighter fit between the drive module and the fixing plate, and further enhancing the overall structure's resistance to loosening under vibration. Since the main support portion is integrally formed on the drive housing 2, it provides stable support for the elastic latching portions 231, ensuring that the elastic latching portions 231 are not easily deformed during long-term use or repeated vibration, maintaining a continuous locking effect, and extending the service life of the structure.

[0036] In a further preferred configuration, the engaging ends of the two elastic buckle parts 231 are each provided with arc-shaped guide slopes. This design plays a guiding and buffering role during installation: when the drive module drives the locking buckle to be installed in the locking hole 13 of the fixed plate 1, the arc-shaped slopes will first contact the edge of the locking hole. Through the smooth transition of the slopes, the installation force perpendicular to the fixed plate 1 is converted into a lateral force that causes the elastic buckle parts 231 to slightly contract inward. Without deliberate alignment or applying excessive pressure, the buckle parts can pass smoothly through the locking hole 13. After passing through the locking hole 13, the elastic buckle parts 231 reset under their own elasticity, so that the flat part of the engaging end will abut against the other side of the fixed plate 1, completing the locking. The whole process does not require tools such as screwdrivers, and can be quickly engaged by manual operation, which greatly reduces the operation threshold and labor intensity of installation.

[0037] To enhance the tightness and reliability of the connection between the drive module and the mounting plate, refer to... Figure 1-2 One end of the fixing plate 1 is provided with a limiting groove 14 adjacent to the limiting hole 11. The drive housing 2 is provided with a corresponding limiting block 24 that abuts against the limiting groove 14. The limiting block 24 blocks the opening of the limiting groove 14 and forms a closed wire passage hole between them. This structure, through the cooperation of the limiting block 24 and the limiting groove 14, further enhances the tightness of the connection between the drive module and the fixing plate 1. It is equivalent to adding an auxiliary positioning point at one end of the fixing plate 1, avoiding local loosening that may be caused by the force of a single limiting hook 21, and enhancing the stability of the installation structure. At the same time, the closed wire passage hole formed by the limiting groove 14 and the limiting block 24 provides a dedicated wire path for the wire, forcing the wire to be arranged along a fixed trajectory, ensuring that the line is neat and orderly, and avoiding the safety hazards caused by messy tangling, thus achieving the wire protection function. In addition, the installation structure also includes an auxiliary fastener 3 set between the fixing plate 1 and the drive housing 2. The auxiliary fastener 3 is preferably an auxiliary screw, which is then used for final locking, taking into account both the needs of quick assembly and precise fixation.

[0038] In this embodiment, combined with Figure 1-3As shown, the locking assembly includes a locking buckle 7 and a locking hook 8 rotatably mounted on the front of the fixed plate 1, and an unlocking spring 9 disposed between the locking buckle 7 and the locking hook 8. The fixed plate 1 has a locking groove. The locking buckle 7 and the locking hook 8 have a locking state where they are rotatably engaged to block the locking groove, and an unlocking state where they are rotatably disengaged to open the locking groove. The drive module has an unlocking wheel 43 rotatably mounted on the outside of the drive housing 2. The unlocking wheel 43 passes through the fixed plate 1 and connects to the locking buckle 7. The top of the unlocking wheel 43 has an unlocking rod 431 offset from its axis. One side of the locking buckle 7 has a connecting groove that mates with the unlocking rod 431. 1. Driven by the unlocking wheel 43, the locking element 7 is pushed to complete the unlocking movement; further, the driving assembly includes a motor 41, a transmission gear set and an unlocking wheel 43 disposed in the electrical control box. The transmission gear set includes a meshing transmission gear and a drive gear 42. The drive gear 42 is coaxially linked with the unlocking wheel 43. The bottom of the unlocking wheel 43 is provided with a push rod 432 that is offset from its axis. The driving housing 2 is provided with an arc guide groove 6 that allows the push rod 432 to make circumferential movements. A return spring 5 is disposed in the arc guide groove 6. When the unlocking wheel 43 drives the locking element 7 to unlock, the push rod 432 squeezes the return spring 5. In this structural configuration, during the unlocking operation of the electric lock, the motor 41 drives the unlocking wheel 43 to rotate forward via the transmission gear set. This causes the unlocking wheel 43 to drive the locking buckle 7 to rotate to the unlocked position. When the unlocking wheel 43 rotates, it drives the push rod 432 to move in the arc guide groove 6 and press one end of the return spring 5. At this time, the arc-shaped return spring 5 will exert a counter-pushing force on the unlocking wheel 43 and the drive gear 42. Correspondingly, during the locking operation of the electric lock, the motor 41 drives the unlocking wheel 43 to rotate in the opposite direction, causing the unlocking wheel 43 to rotate away from the locking buckle 7. This makes way for the locking movement of the locking buckle 7 and drives the push rod 432 to move along the arc guide groove 6 and press the other end of the return spring 5. In summary, the return spring 5 uses its elastic force to drive the unlocking wheel 43 and the drive gear 42 to rotate a certain distance, causing the drive gear 42 to briefly disengage and then re-engage with the transmission gear. This releases the gear meshing force during the disengagement process to prevent jamming, effectively protecting the motor and ensuring the stability and reliability of the transmission between the motor, gear assembly, and unlocking wheel. In this text, forward and reverse rotation refer to two rotations of a component in opposite directions, not to its actual rotation direction.

[0039] For further optimization settings, refer to Figure 3The unlocking wheel 43 includes an annular base 433 covering the opening of the arc guide groove 6. The push rod 432 is disposed on the annular base 433. The arc guide groove 6 includes a positioning groove section for positioning and installing the return spring 5, and two sets of limiting bosses 61 disposed at both ends of the positioning groove section. The return spring 5 is an arc-shaped spring structure, and its two ends are limited and abut against the two sets of limiting bosses 61. When the push rod 432 rotates into the positioning groove section, it squeezes one end of the return spring 5. In this structural configuration, the unlocking wheel 43 blocks the top opening of the arc guide groove 6 through the annular base 433. This restricts the return spring 5 from disengaging from the top opening of the arc guide groove, thus positioning the return spring 5 in the positioning groove section of the arc guide groove 6. Two sets of limiting bosses 61 limit the ends of the arc spring. Since the push rod 432 reciprocates along the arc guide groove, the unlocking wheel 43 can drive the push rod 432 to compress the return spring 5 when rotating forward or backward under the drive of the motor. The elastic force of the arc spring under compression is used to push the unlocking wheel 43 and the drive gear 42 to achieve the purpose of rotation.

[0040] like Figure 1 As shown, the fixing plate 1 is provided with a signal detection switch 10 located on the movement path of the locking hook 8. The signal detection switch 10 is located close to the limiting groove 14, so that the line connected to the signal detection switch 10 passes through the limiting groove 14. The opening of the limiting groove 14 is blocked by the limiting block 24, which can prevent the line of the signal detection switch 10 from leaving the limiting groove 14. The unlocking or locking status of the electric seat pad lock can be detected by the contact or separation between the signal detection switch 10 and the locking hook 8.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
