DETAILED DESCRIPTION

[0038] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0039] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the devices or elements indicated by the terms to have a specific orientation, to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0041] Referring to Figures 4-6 The present application provides a movement assembly, which comprises a drive mechanism 1, a transmission mechanism 2 and a gear set 3. The transmission mechanism 2 is arranged side by side with the drive mechanism 1. The transmission mechanism 2 comprises a screw rod 21 and a nut 22 threadedly connected with the screw rod 21. The gear set 3 is drivingly connected with an output end of the drive mechanism 1 and an axial end of the screw rod 21, so that the drive mechanism 1 is drivingly connected with the transmission mechanism 2 through the gear set 3. When the drive mechanism 1 drives the screw rod 21 to rotate through the gear set 3, the screw rod 21 drives the nut 22 to reciprocate along the axial direction of the screw rod 21.

[0042] The driving mechanism 1 and the transmission mechanism 2 are arranged side by side, and can be arranged on the same horizontal plane, or arranged vertically. For example, when the movement assembly is installed, if the installation space is sufficient on the same horizontal plane, the driving mechanism 1 can be installed on one side of the transmission mechanism 2 on the same horizontal plane; if the installation space is sufficient in the vertical direction, the driving mechanism 1 can be installed above or below the transmission mechanism 2. Whether the driving mechanism 1 and the transmission mechanism 2 are arranged on the same horizontal plane or vertically, it is necessary to ensure that there is a gap between the driving mechanism 1 and the transmission mechanism 2, so as not to affect the independent movement of the two.

[0043] Compared with the existing driving mechanism 1 and transmission mechanism 2 linear connection structure, the driving mechanism 1 and the transmission mechanism 2 of the utility model are arranged side by side and are connected through the gear set 3, on the one hand, the driving mechanism 1 can drive the screw rod 21 to rotate through the gear set 3, so that the screw rod 21 drives the nut 22 to reciprocate along the axial direction, thereby ensuring the transmission effect of the movement assembly; on the other hand, the side-by-side arrangement of the driving mechanism 1 and the transmission mechanism 2 can shorten the length of the movement assembly, thereby reducing the space occupied by the movement assembly.

[0044] In the utility model, the driving mechanism 1 includes a motor 11, and the output shaft 111 of the motor 11 is in transmission connection with the gear set 3. The utility model takes the driving mechanism 1 installed below the transmission mechanism 2 as an example for description, the output shaft 111 of the motor 11 rotates, and the rotation of the output shaft 111 is transmitted to the gear set 3 to drive the screw rod 21 to rotate, so that the screw rod 21 drives the nut 22 to reciprocate along the axial direction of the screw rod 21.

[0045] The gear set 3 includes a first gear 31 and a second gear 32, the first gear 31 is connected with the output shaft 111, the second gear 32 is connected with one end of the screw rod 21 in the axial direction, and the first gear 31 and the second gear 32 are in meshing connection. The first gear 31 can be fixedly connected with the end portion of the output shaft 111, or can be sleeved on the output shaft 111. Similarly, the second gear 32 can be fixedly connected with the end portion of one end of the screw rod 21 in the axial direction, or can be sleeved on one end of the screw rod 21 in the axial direction. In this way, the rotation of the output shaft 111 of the motor 11 can drive the first gear 31 to rotate synchronously, and the first gear 31 and the second gear 32 are in meshing connection, so that the second gear 32 is driven to rotate synchronously, thereby driving the screw rod 21 to rotate through the second gear 32, so that the screw rod 21 drives the nut 22 to reciprocate along the axial direction of the screw rod 21.

[0046] The first gear 31 and the second gear 32 are connected in meshing through at least one third gear 33. Since the transmission mechanism 2 and the driving mechanism 1 occupy a certain space in the side-by-side direction, and the driving mechanism 1 and the transmission mechanism 2 are arranged at intervals, when the sizes of the first gear 31 and the second gear 32 are small, the meshing between the first gear 31 and the second gear 32 can not be achieved, at this time, a proper number and size of the third gear 33 are arranged according to the interval between the first gear 31 and the second gear 32, so as to achieve the meshing between the first gear 31 and the second gear 32 through the third gear 33, thereby ensuring the transmission connection effect of the driving mechanism 1 and the transmission mechanism 2 through the gear set 3.

[0047] Based on the above structure, the transmission mechanism 2 further comprises a transmission base, the transmission base comprises a first fixed seat 23 and a second fixed seat 24 arranged at the two axial ends of the lead screw 21, the axial one end of the lead screw 21 is connected to the gear set 3 through the first fixed seat 23, the axial other end of the lead screw 21 is rotatably arranged in the second fixed seat 24, and the axial other end of the lead screw 21 is connected to the second fixed seat 24 through the buffer 25. The transmission base plays a role of bearing the lead screw 21 without affecting the rotation of the lead screw 21, and can limit the rotation axis of the lead screw 21 to prevent rotation deviation. The axial other end of the lead screw 21 penetrates into the second fixed seat 24 and abuts against the second fixed seat 24 through the buffer 25, which can move the buffer 25 relative to the second fixed seat 24 when the lead screw 21 is extruded by external force, thereby buffering and protecting the lead screw 21 by the buffer 25, reducing the deformation and damage of the lead screw 21 caused by external force extrusion, and simultaneously playing a buffering role for the flap 3 in the locking state when the core assembly is installed in the parking lock.

[0048] The buffer 25 can be a spring or a rubber piece.

[0049] The axial one end of the lead screw 21 is connected to the gear set 3 through the first fixed seat 23, the gear set 3 can be arranged outside the first fixed seat 23, the axial one end of the lead screw 21 penetrates through the first fixed seat 23 to connect the gear set 3, and the gear set 3 is connected to the output shaft 111 of the motor 11. Alternatively, in the utility model, the gear set 3 is arranged on the first fixed seat 23, the axial one end of the lead screw 21 penetrates into the first fixed seat 23 to connect the second gear 32, and the output shaft 111 penetrates into the first fixed seat 23 to connect the first gear 31. The first fixed seat 23 is provided with a mounting groove for the rotation of the gear set 3, and the axial one end of the lead screw 21 and the output shaft 111 of the motor 11 both penetrate into the mounting groove of the first fixed seat 23 to connect the second gear 32 and the first gear 31 respectively, thereby realizing the transmission connection of the driving mechanism 1 and the transmission mechanism 2 through the gear set 3. The gear set 3 is mounted on the first fixed seat, which can reduce the volume and space occupied by the core assembly.

[0050] The end of the motor 11 with the output shaft 111 is provided with a mounting portion 112, which is fixed on the first fixed seat 23. When the output shaft 111 is connected to the first gear 31 in the first fixed seat 23, the mounting portion 112 is arranged in abutment with the first fixed seat 23 and is fixed by the bolt 4 to ensure the stability of the installation of the motor 11 and thus ensure the transmission effect.

[0051] In addition to the above basic structure, the outer wall of the screw rod 21 is sleeved with an elastic and retractable sealing sleeve 26 along the axial direction. The inner wall of the sealing sleeve 26 is spaced apart from the outer wall of the screw rod 21. The sealing sleeve 26 is arranged at the axial two ends of the nut 22 and is sealingly connected with the nut 22 and the transmission base. Specifically, the outer wall of the screw rod 21 is sleeved with two elastic and retractable sealing sleeves 26 along the axial direction. The inner walls of the two sealing sleeves 26 are both spaced apart from the outer wall of the screw rod 21. The nut 22 is arranged between the two sealing sleeves 26. The axial two ends of the nut 22 are respectively sealingly connected with one end of the corresponding sealing sleeve 26. The other ends of the two sealing sleeves 26 are respectively sealingly connected with the first fixed seat 23 and the second fixed seat 24. When the driving mechanism 1 drives the screw rod 21 to rotate through the gear set 3 to drive the nut 22 to reciprocate along the axial direction of the screw rod 21, the corresponding sealing sleeve 26 can be extruded, and the other sealing sleeve 26 can be elongated, so that the sealing sleeve 26 can always seal the screw rod 21 to achieve the effect of waterproofing.

[0052] In combination Figure 3 , the transmission mechanism 2 further comprises a guide plate 28. The nut 22 is slidingly connected with the guide plate 28, and the guide plate 28 limits the displacement of the nut 22 perpendicular to the sliding direction on the guide plate 28. The guide plate 28 can be provided with one or two guide plates. The guide plate 28 is fixedly connected with the first fixed seat 23 and the second fixed seat 24 through the bolt 4 and / or the pin shaft 10, which has a guiding effect, so that the rotation of the screw rod 21 and the axial movement of the nut 22 are both along the guide plate 28, avoiding the deviation of the action. Moreover, the guide plate 28 has a moving protection and shock absorption effect. Based on the sliding connection relationship between the guide plate 28 and the nut 22, the guide plate 28 can not only assist the linear movement of the nut 22, but also limit the displacement perpendicular to the direction when it is impacted by external force, so as to offset the external impact force, thereby protecting the nut 22 and avoiding deformation or damage.

[0053] The guide plate 28 is provided with a guide groove 281, and the nut 22 is provided with a sliding block 221 matched with the guide groove 281. The guide groove 281 limits the displacement of the sliding block 221 perpendicular to the sliding direction. During the axial movement of the nut 22 along the screw rod 21, the sliding block 221 is always in abutment in the guide groove 281. In this way, the impact force received by the nut 22 can be transmitted to the sliding block 221, and then transmitted to the installation position by the guide plate 28, thereby achieving the effect of protecting the nut 22 and the screw rod 21.

[0054] And, the guide plate 28 is provided with a fixing hole 282 corresponding to the motor 11, and the side wall of the motor 11 is provided with a matched fixing shaft 113 corresponding to the fixing hole 282, the fixing shaft 113 is arranged in the fixing hole 282 and avoids the sliding of the nut 22. On the basis of not affecting the sliding effect of the nut 22, the fixing shaft 113 is fixed in the fixing hole 282, can be matched with the mounting portion 112 fixed on the first fixing seat 23, and the stability of the motor 11 installation is further improved.

[0055] The upper cover of the screw rod 21 and the nut 22 is provided with a protective cover 29, both ends of the protective cover 29 are fixed on the first fixing seat 23 and the second fixing seat 24 respectively, and the protective cover 29 is arranged at a distance from the screw rod 21 and the nut 22. The protective cover 29 protects the screw rod 21 and the nut 22 from external impact. The protective cover 29 is fixed on the first fixing seat 23 and the second fixing seat 24 by bolts 4.

[0056] Referring to Figures 1-4 The utility model also provides a parking stall lock, which comprises a mounting seat 5, a flap 6, a connecting arm 7 and the above-mentioned movement assembly, the flap 6 and the movement assembly are both mounted on the mounting seat 5, and the two ends of the connecting arm 7 are rotatably connected to the nut 22 and the flap 6 respectively. The driving mechanism 1 drives the screw rod 21 to rotate through the gear set 3, so as to drive the nut 22 to reciprocate along the axial direction of the screw rod 21, simultaneously drive the connecting arm 7 to move synchronously and rotate relative to the nut 22, so that the connecting arm 7 drives the flap 6 to rotate to a closed state or an open state.

[0057] The movement assembly can be installed on the side of the flap 6 or the side of the flap 6 facing the mounting seat 5. The nut 22 is provided with a connecting block 222 to rotatably connect the connecting arm 7, the connecting block 222 is connected to one end of the sliding block 221 away from the guide plate 28, so that the structure of the nut 22 is more compact, and the impact force received by the flap 6 can be transferred by the guide plate 28 to prevent damage to the flap 6, the connecting arm 7 and the movement assembly. The number of the connecting arm 7 can be one, two or more than two according to requirements.

[0058] Although the driving mechanism 1 and the transmission mechanism 2 are arranged side by side and are not directly connected, they are transmissionally connected through the gear set 3. In this way, the driving mechanism 1 can be controlled by the control box 9, so that the driving mechanism 1 can drive the screw rod 21 to rotate through the gear set 3, so that the screw rod 21 drives the nut 22 to reciprocate along its axial direction, thereby ensuring the transmission effect of the movement assembly, so that when applied to the parking stall lock, the movement assembly can be used to realize the rotation of the flap 6 to the closed state or the open state through the connecting arm 7, so as to realize the closing or opening of the parking stall lock. Moreover, the side-by-side arrangement of the driving mechanism 1 and the transmission mechanism 2 can shorten the length of the movement assembly, thereby reducing the space occupied by the movement assembly. When the movement assembly is applied to the parking stall lock, it is beneficial to reduce the volume of the parking stall lock, realize the miniaturization of the parking stall lock, and facilitate the selection of the installation position of the parking stall lock.

[0060] The central axes of the main shaft 61 and the connecting shaft 62 are offset, when the motor 11 drives the screw rod 21 to rotate, the screw rod 21 drives the nut 22 to slide along the guide plate 28, and the connecting arm 7 slides along the nut 22 and rotates relative to the nut 22, the connecting arm 7 drives the flap 6 to flip around the main shaft 61 to the closed state or the open state, so that the motor 11 can drive the flap 6 to flip with a small torque, and the movement amplitude of the connecting arm 7 is small, which is beneficial to realize the miniaturization design of the parking lock.

[0061] The flap 6 is provided with a containing groove 63 for avoiding the connecting arm 7 in the rotation process of the flap 6, and the connecting shaft 62 is arranged in the containing groove 63 and connected with the connecting arm 7. The containing groove 63 needs to ensure the connection between the connecting arm 7 and the connecting shaft 62, and also needs to provide enough space for the movement of the connecting arm 7, so as not to affect the complete closing of the flap 6.
