Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to a chassis and a parking lock. Background Art

[0002] Parking locks are usually installed on parking spaces to prevent others from occupying private or paid parking spaces at will. They allow vehicles to park at any time without the need for personnel management. For paid parking spaces, parking locks usually drive a baffle to stand up to lock the parking space through the chassis. The baffle will only be lowered after the parking fee is settled, and the vehicle can leave.

[0003] Among them, a driving mechanism and a transmission arm are provided in the chassis, and the two ends of the transmission arm are respectively connected to the power output end of the driving mechanism and the rotatable baffle. Since the transmission arm moves up and down in an inclined upward direction during the transmission process, when the transmission arm is arranged in the chassis, the height of the chassis needs to be set higher to provide height space for the transmission arm to move up and down. In addition, in the chassis of the prior art, the signal module in the control component is installed on the top of the chassis, which will also increase the height of the chassis. When the height of the chassis is set higher, when the vehicle is parked in the parking lock, the door may hit the chassis when it is opened, thereby affecting the opening of the door. Moreover, when the height of the chassis is set higher, it will also affect people getting off the vehicle, such as blocking or tripping the feet of people getting off the vehicle.

[0004] Therefore, there is an urgent need for a chassis and a parking lock to overcome the above-mentioned defects. Utility Model Content

[0005] In order to overcome at least one of the defects described in the above-mentioned prior art, one of the objects of the present utility model is to provide a chassis, which can design the height of the chassis shell to be smaller without affecting the movement range of the power output end of the drive component, thereby avoiding the impact of the high height of the chassis on opening the door and getting off the vehicle.

[0006] The second purpose of the utility model is to provide a parking lock, in which the movement range of the power output end of the driving component in the chassis is not affected by the height of the chassis, so the height of the chassis shell can be designed to be smaller, so that the parking lock is relatively flat as a whole, avoiding the influence of the high height of the chassis on opening the car door and getting off the car.

[0007] One of the technical solutions adopted by the utility model to solve the problem is:

[0008] A chassis is installed on a parking lock, comprising a chassis shell and a driving component arranged in the chassis shell. A guide groove is provided on the side of the chassis shell, and the opening of the guide groove extends from the side of the chassis shell to the top surface of the chassis shell. The guide groove passes through the outside of the chassis shell to the inside of the chassis shell; the power output end of the driving component slides in the guide groove so that the power output end of the driving component extends out or retracts into the guide groove.

[0009] Thus, the power output end of the drive assembly can extend out of the top surface of the chassis shell through the upward opening portion of the guide groove, so that the inclined upward movement of the power output end of the drive assembly is not restricted by the height of the chassis shell, thereby reducing the height of the chassis shell as much as possible, thereby preventing the high height of the chassis from affecting the opening of the door and getting off the vehicle.

[0010] Furthermore, the opening of the guide groove on the side of the chassis shell is a first opening, and the opening of the guide groove on the top surface of the chassis shell is a second opening. The power output end of the drive component drives the flap of the parking lock to rotate through the first opening and the second opening, and the power output end of the drive component can extend out of the top surface of the chassis shell through the second opening.

[0011] Therefore, the power output end of the driving component can drive the flap to rotate through the first opening on the side, and the flap and the chassis shell can be arranged side by side to reduce the overall height of the parking lock; the power output end of the driving component can extend out of the top surface of the chassis shell through the second opening, so that the inclined upward movement of the power output end is not restricted by the height of the chassis shell, thereby allowing the height of the chassis shell to be reduced when it is set.

[0012] Furthermore, a guiding surface is provided in the guiding groove, and the guiding surface is arranged opposite to the power output end of the driving assembly; the power output end of the driving assembly slides along the guiding surface.

[0013] Therefore, the guide surface can support the power output end of the drive assembly to enhance the transmission force of the drive assembly; and can guide the power output end to move up and down to ensure the stability of the transmission process of the drive assembly.

[0014] Further, the guide surface is an arc-shaped guide surface, and the guide surface includes a first arc segment, a slope segment and a second arc segment connected in sequence along the sliding direction of the power output end, the first arc segment is a convex arc toward the power output end of the drive component, and the second arc segment is a concave arc toward the power output end of the drive component, and the power output end of the drive component slides into the guide surface through the first arc segment and slides out of the guide groove through the second arc segment.

[0015] Therefore, the guiding surface is an arc-shaped guiding surface, so that the guiding groove can better accommodate the power output end of the driving assembly, which is beneficial to the rotation of the power output end of the driving assembly.

[0016] Furthermore, the width of the guide surface is not less than the width of the power output end of the drive assembly.

[0017] In this way, the supporting effect of the guide surface on the driving assembly can be better ensured, and it is beneficial for the driving assembly to slide thereon, thereby ensuring the transmission stability of the driving assembly.

[0018] Furthermore, the power output end of the driving assembly includes a transmission member, and the power output end of the transmission member extends into the guide groove and can slide in the guide groove.

[0019] Therefore, when the driving assembly drives the power input end of the transmission member to move, the power input end of the transmission member drives the power output end of the transmission member to slide in the guide groove, and the power output end of the transmission member slides in the guide groove and drives the flap to flip.

[0020] Furthermore, the driving assembly includes a motor, a screw and a nut, one end of the screw is connected to the output shaft of the motor, and the nut is threadedly connected to the screw; the transmission member includes a connecting arm, the power input end of the connecting arm is rotatably connected to the nut, and the power output end of the connecting arm extends into the guide groove and can slide in the guide groove.

[0021] Therefore, the cooperation of the screw and the nut can convert the rotational motion of the motor into the forward and backward motion of the nut, and the connecting arm can convert the forward and backward motion into the up and down motion. In this way, the driving assembly can drive the flap to rotate around the rotating axis through the transmission action of the connecting arm, and the driving system formed in this way has a compact connection and stable transmission.

[0022] Furthermore, the chassis shell is provided with an installation opening, the installation opening is provided with a guide block, the guide block is provided with a slide rail parallel to the axial direction of the screw, the nut is provided with a slider that cooperates with the slide rail, and the nut is slidably connected to the guide block through the slider and the slide rail.

[0023] Therefore, the guide block can limit the nut from sliding along the axial direction of the screw, so that the connecting arm can drive the flap to rotate more smoothly; and the guide block supports the nut through the slider, so that the nut can slide more smoothly in a straight line; More importantly, when the connecting arm drives the flap to rotate, the pressure from the flap is transmitted to the slide rail, and does not act on the screw through the nut, which can protect the screw.

[0024] Furthermore, a keyhole is provided on the chassis shell, and an unlocking slot is provided on the screw rod, and the unlocking slot is arranged opposite to the keyhole.

[0025] Therefore, when the motor has a problem and cannot automatically raise or lower the flap, the key can be inserted into the unlocking slot at one end of the screw rod through the keyhole, and the screw rod can be rotated forward or reversed by turning the key, thereby manually raising or lowering the flap.

[0026] Furthermore, a mounting hole is provided on the side of the chassis shell, and a signal module of the parking lock is installed in the mounting hole.

[0027] Therefore, there is no need to set the signal module on the top of the chassis, which can reduce the height of the chassis; and the signal module is set on a side of the chassis away from the flap, which can prevent the flap or other components from interfering with the signal module.

[0028] Furthermore, a speaker hole is provided on the side of the chassis shell, and the speaker of the parking lock is located inside the chassis shell, and the speaker of the parking lock is directly opposite to the speaker hole.

[0029] Thus, while the chassis shell protects the speaker components, the sound of the speaker can also penetrate the chassis shell and be transmitted to the outside.

[0030] Furthermore, a scanning area for setting a charging code is provided on the top surface of the chassis shell.

[0031] The second technical solution adopted by the utility model to solve the problem is:

[0032] A parking lock comprises a support seat, a flap and the above-mentioned chassis, wherein the flap is rotatably connected to the support seat via a rotating shaft; a driving shaft is provided on the flap, and the driving shaft is rotatably connected to the power output end of the transmission member; the axis of the rotating shaft is parallel to the axis of the driving shaft and is arranged at intervals, and the power output end of the driving assembly drives the flap to rotate around the rotating shaft via the driving shaft.

[0033] Therefore, the flap can be installed on the ground or base through a support seat. When the flap is driven to flip, the driving component in the chassis is started, the driving component drives the transmission member to move, and the transmission member drives the drive shaft to move, so that the flap rotates around the rotating axis, and the active side of the flap approaches or moves away from the ground during the rotation process.

[0034] In addition, the axis of the rotating shaft is arranged parallel to the axis of the driving shaft, which can ensure that there is a certain lever arm between the driving shaft and the rotating shaft. When pushing the flap to rotate, the existence of the lever arm can effectively reduce the force, making the rotation of the flap more labor-saving.

[0035] Furthermore, the rotating shaft is arranged on one side of the flap, and the distance between the driving shaft and the rotating shaft is not greater than half of the width of the flap.

[0036] Therefore, the larger the distance between the driving shaft and the rotating shaft, the longer the force arm is, and the less effort is required according to the lever principle; therefore, the driving shaft can drive the flap to rotate around the rotating shaft with less effort.

[0037] In summary, the chassis and parking lock provided by the utility model have the following technical effects:

[0038] 1) The chassis shell is provided with a guide groove that runs through the inside and outside of the chassis shell, so that the power output end of the driving component in the chassis can slide in the guide groove, and the opening of the guide groove extends from the side of the chassis shell to the top surface of the chassis shell, so that the power output end of the driving component can extend to the top surface of the chassis shell, thereby avoiding the limitation of the height movement of the power output end by the height of the chassis shell, achieving the purpose of designing a shorter chassis height, and avoiding the influence of the high chassis height on the opening and getting off of the car;

[0039] 2) A parking lock having the above-mentioned chassis, wherein a guide groove is provided in the chassis, and the opening of the guide groove extends from the side of the chassis shell to the top surface of the chassis shell, so that when the driving flap is rotated, the power output end of the driving component in the chassis can extend out of the top surface of the chassis shell through the guide groove, so that the height of the chassis shell can be designed to be as small as possible, thereby realizing a flat and ultra-thin design of the parking lock.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0054] Embodiment 1

[0055] See also Figure 1 , Figure 2 and Figure 3 The utility model discloses a chassis, referring to Figure 4The chassis is installed on the parking lock, the parking lock includes a flap 21, and the chassis is installed on one end of the flap 21. Specifically, the chassis includes a chassis shell 1, and a driving component arranged in the chassis shell 1. A guide groove 12 is arranged on a side of the chassis shell 1 close to the flap 21. The guide groove 12 runs from the outside of the chassis shell 1 to the inside of the chassis shell 1, and the opening of the guide groove 12 extends from the side of the chassis shell 1 to the top surface of the chassis shell 1. Figure 3 The power output end of the driving component is located in the guide groove 12 and can slide in the guide groove 12 so that the power output end of the driving component extends out or retracts into the guide groove 12.

[0056] On the basis of this structure, when using the chassis of the utility model, refer to Figure 3 As shown, the chassis shell 1 can be installed on the base 20 of the parking lock. At the same time, the chassis shell 1 covers the periphery of the driving component and the control component of the parking lock, and various accessories can be fixed. In addition, the hard chassis shell 1 can play a supporting and protective role.

[0057] Specifically, when the parking lock is in use, see Figures 4 to 7 As shown, the driving component drives the flap 21 of the parking lock to flip, and the flap 21 can rise or fall relative to the ground after flipping, so that the parking lock can be used in a locked state to lock the parking space or in an unlocked state to unlock the parking space. When the flap 21 is raised, one use scenario is that external vehicles cannot enter the private parking space, which can protect the private parking space from being occupied; another use scenario is that vehicles in the paid parking space cannot exit the parking space, and the flap 21 can only be unlocked after the owner settles the parking fee, which can realize the unmanned management mode of the paid parking space.

[0058] In the parking lock, the power output end of the driving component is driven to swing and drive the flap 21 of the parking lock to flip, while the driving component and its power output end in the prior art are sealed together inside the chassis shell, and only the flap passes through the side of the chassis shell through a rotating shaft to connect with the power output end of the driving component inside the chassis shell. Since the power output end of the transmission member has a large displacement in the height direction when the transmission member is driven to swing inside the chassis shell, in order to avoid the movement of the transmission member being restricted, the height of the existing chassis shell is set higher to ensure sufficient height space to accommodate the vertical movement of the transmission member. However, when the height of the chassis shell is higher, when the vehicle is parked at the parking lock, the door may hit the chassis when it is opened, thereby affecting the opening of the door; in addition, the higher height of the chassis will also affect people getting off the vehicle, such as blocking or tripping the feet of people getting off the vehicle.

[0059] Therefore, in order to avoid the above situation, see Figures 1 to 4As shown, the utility model sets a guide groove 12 on the side of the chassis shell 1, and the guide groove 12 runs from the outside of the chassis shell 1 to the inside of the chassis shell 1. It is worth noting that the opening of the guide groove 12 extends from the side of the chassis shell 1 to the top surface of the chassis shell 1. Among them, since the guide groove 12 runs through the inside and outside of the chassis shell 1, the power output end of the drive component in the chassis shell 1 can pass through the chassis shell 1 to extend into the guide groove 12, and the drive component is located in the chassis shell 1. In addition, the opening of the guide groove 12 extends from the side of the chassis shell 1 to the top surface of the chassis shell 1, so the power output end of the drive component can extend to the top surface of the chassis shell 1 through the opening of the guide groove 12 when it is driven to swing.

[0060] It should be noted that the chassis shell 1 includes two oppositely disposed side surfaces, two oppositely disposed end surfaces, and a top surface, the two side surfaces and the two end surfaces together enclose a storage space for accommodating the drive assembly and the control module, and the top surface is connected to the two side surfaces and the upper part of the two end surfaces to cover the upper part of the storage space. Among them, the guide groove 12 is provided on the side surface of the chassis shell 1 facing the parking lock flap 21, and the opening of the guide groove 12 extends from the side surface of the chassis shell 1 to the top surface of the chassis shell 1, so that the storage space is open to the parking lock flap 21 and the upper part of the chassis.

[0061] Thus, by providing the guide groove 12, the power output end of the driving assembly can be placed outside the chassis housing 1, and the power output end can be extended or retracted under the guidance of the guide groove 12, so that the inclined upward movement of the power output end is not limited by the height of the chassis housing 1, so that the height of the chassis housing 1 can be reduced as much as possible. When the height of the chassis housing 1 is designed to be small, when the vehicle is parked in the parking space and locked, the door will not hit the chassis when it is opened, and it is not easy to block or trip the feet of the person getting off the vehicle.

[0062] In this embodiment, the opening of the guide groove 12 on the side of the chassis shell 1 is a first opening 122, and the opening of the guide groove 12 on the top surface of the chassis shell 1 is a second opening 123. Figure 4 The power output end of the driving assembly drives the flap 21 of the parking lock to rotate through the first opening 122. After the flap 21 rotates to the right position, refer to Figure 6 The power output end of the driving assembly can extend out of the top surface of the chassis shell 1 through the second opening 123 .

[0063] Since the power output end of the driving assembly drives the flap 21 of the parking lock to rotate through the first opening 122 and the second opening 123, the flap 21 can move up and down under the drive of the power output end of the driving assembly. Figure 7 and Figure 8The power output end of the driving assembly is rotatably connected to the driving shaft 22 of the flap 21, and the power output end of the driving assembly drives the flap 21 to rotate around the rotation axis 23 through the driving shaft 22. The flap 21 is rotatably connected to the base 20 of the parking lock or the ground through the rotation axis 23, and the flap 21 realizes locking or unlocking of the parking lock during the rotation process.

[0064] Therefore, when the chassis shell 1 is installed on the parking lock, in order to enable the power output end of the driving component to drive the flap 21 to rotate through the first opening 122 on the side of the chassis shell 1 and the second opening 123 on the top thereof, the flap 21 is facing the side of the chassis shell 1 at one end in its length direction.

[0065] In this embodiment, a guide surface 121 is provided in the guide groove 12 , and the guide surface 121 is arranged opposite to the power output end of the driving assembly, and the power output end of the driving assembly can slide on the guide surface 121 .

[0066] Specifically, the guide surface 121 is arranged at the bottom of the guide groove 12 and is arranged opposite to the power output end of the drive assembly. When the drive assembly drives the flap 21 to flip, the power output end of the drive assembly rotates in the guide groove 12 and moves up and down. If the bottom of the guide groove 12 is suspended, the power output end has a small transmission force and is unstable without bottom support, and it is difficult to drive the flap 21 to rotate while bearing the gravity of the flap 21. Even if the drive assembly can drive the flap 21 to flip, the connection strength between the flap 21 and the power output end of the drive assembly is weak, and the transmission is prone to failure when subjected to external forces.

[0067] Therefore, by setting a guide surface 121 at the bottom of the guide groove 12, and the guide surface 121 is set opposite to the power output end of the driving component, when the power output end of the driving component extends out of or retracts into the guide groove 12 through the second opening 123, the guide surface 121 can support the power output end of the driving component, enhance the transmission force of the driving component, and guide the power output end of the driving component to make an inclined up and down movement along the guide surface 121, thereby ensuring the stability of the transmission process of the driving component.

[0068] Furthermore, the guide surface 121 includes a first arc segment 1211, a slope segment 1212, and a second arc segment 1213 connected in sequence along the sliding direction of the power output end of the drive assembly, and the first arc segment 1211 is a convex arc toward the power output end of the drive assembly, and the second arc segment 1213 is a concave arc toward the inside of the power output end of the drive assembly. The power output end of the drive assembly slides into the guide surface 121 through the first arc segment 1211, and slides out of the guide groove 12 through the second arc segment 1213.

[0069] Specifically, the chassis shell 1 is bent downward at the side and top surfaces where the guide groove 12 is opened to form a guide surface 121, wherein the first arc segment 1211 protrudes toward the power output end of the drive assembly, which is beneficial for the power output end of the drive assembly to first abut against the first arc segment 1211 and enter the inclined surface segment 1212 with the help of force; then, the power output end of the drive assembly enters the second arc segment 1213 along the inclined surface segment 1212. Since the second arc segment 1213 is recessed toward the power output end of the drive assembly, the guide surface 121 can more smoothly guide the power output end of the drive assembly to extend upward out of the second opening 123, thereby achieving the locking of the flap 21 in place.

[0070] In this embodiment, the width of the guide surface 121 is not less than the width of the power output end of the driving assembly.

[0071] Since the guide surface 121 can support the power output end of the drive assembly, when the width of the guide surface 121 is greater than or equal to the width of the power output end of the drive assembly, the support effect can be better ensured and the transmission strength of the drive assembly can be enhanced. In addition, when the width of the guide surface 121 is set wider, it is conducive to the power output end of the drive assembly sliding thereon, ensuring the transmission stability of the drive assembly.

[0072] In this embodiment, the power output end of the driving assembly includes a transmission member 15 , and the power output end of the transmission member 15 extends into the guide groove 12 and can slide in the guide groove 12 .

[0073] Among them, the transmission member 15 has a power input end and a power output end, and the two ends of the transmission member 15 are respectively rotatably connected with the driving component in the chassis and the flap 21 outside the chassis. The power input end of the transmission member 15 makes a forward and backward translational motion under the drive of the driving component, and at the same time drives the power output end of the transmission member 15 to slide in the guide groove 12. The power output end of the transmission member 15 extends into the guide groove 12 and is connected to the flap 21 on the side of the chassis, so that the power output end of the transmission member 15 drives the flap 21 to rotate around the rotating shaft 23, and at the same time, the power output end of the transmission member 15 produces an inclined upward displacement with the rotation of the flap 21.

[0074] Among them, the opening of the guide groove 12 extends from the side of the chassis shell 1 to the top surface of the chassis shell 1, so the power output end of the transmission member 15 can extend from the guide groove 12 to the top surface of the chassis shell 1 during the transmission process, so that the oblique upward movement of the transmission member 15 is not limited by the internal height of the chassis. Therefore, the overall height of the chassis of the utility model can be set to be relatively small, which can prevent the vehicle from colliding with the chassis during the process of opening the door in the parking space. In addition, the height of the chassis is relatively small, and it is not easy to trip pedestrians, which is conducive to improving road safety.

[0075] In this embodiment, see Figure 5The driving assembly includes a motor 16, a screw 17 and a nut 18, one end of the screw 17 is connected to the output shaft of the motor 16, and the nut 18 is threadedly connected to the screw 17. The transmission member 15 includes a connecting arm, wherein the power input end of the connecting arm is rotatably connected to the nut 18, and the power output end of the connecting arm extends into the guide groove 12 and can slide in the guide groove 12.

[0076] Based on this structure, the extension direction of the connecting arm is the same as that of the screw 17; when the transmission is performed, the motor 16 is started and drives the screw 17 to rotate through the motor output shaft, and the rotation of the screw 17 drives the nut 18 to move forward and backward on the screw 17. Since the power input end of the connecting arm is connected to the nut 18, the nut 18 will drive the power input end of the connecting arm to move forward and backward. Since the power output end of the connecting arm rotates to connect the flap 21, the power input end of the connecting arm will drive the power output end of the connecting arm to tilt up and down in the guide groove 12 during the forward and backward movement, and then the power output end of the connecting arm drives the flap 21 to rotate.

[0077] Among them, the screw 17 and the nut 18 can cooperate to convert the rotational motion of the motor 16 into the forward and backward linear motion of the nut 18, and the connecting arm can convert the forward and backward linear motion into the inclined up and down motion. In this way, the driving component can drive the flap 21 to rotate around the rotating shaft 23 through the transmission action of the connecting arm, so that the flap 21 rises and locks or falls and unlocks relative to the ground during the rotation process. The driving system formed in this way has a compact connection and stable transmission.

[0078] In addition, the transmission member 15 may also include a drive shaft 22, one end of the drive shaft 22 is connected to the power output end of the connecting arm, and the other end of the drive shaft 22 is fixed to the flap 21 of the parking lock, so that the connecting arm can drive the flap 21 to rotate around the rotating shaft 23 through the drive shaft 22, thereby raising and lowering the flap 21.

[0079] Further, see Figure 1 The chassis housing 1 is provided with a mounting opening 10, see Figure 3 A guide block 101 is provided in the installation opening 10, and a slide rail parallel to the axial direction of the screw rod 17 is provided on the guide block 101. Figure 5 The nut 18 is provided with a slider 102 that cooperates with the slide rail, and the nut 18 is slidably connected to the guide block 101 through the slider 102 and the slide rail.

[0080] The guide block 101 is connected to the base 20 by fasteners such as screws, and the slider 102 is arranged on the side of the nut 18 facing the connecting arm. When in use, the guide block 101 can limit the sliding of the nut 18 along the axis direction of the screw 17, and prevent the nut 18 from rotating under the drive of the screw 17, thereby ensuring the driving accuracy of the drive assembly. As a result, the nut 18 can move along the axis direction of the screw 17 under the guiding sliding action of the guide block 101, thereby driving the connecting arm to convert the forward and backward movement of the power input end into the inclined up and down movement of the power output end, so that the connecting arm drives the flap 21 to rotate more smoothly.

[0081] What is important is that when the connecting arm drives the flap 21 to rotate, the pressure exerted by the flap 21 on the connecting arm can be transmitted to the slide rail via the guide block 101, and will not act on the screw 17 via the nut 18. This can reduce the load borne by the transmission components such as the nut 18 and the screw 17 during the transmission process, and protect the screw 17.

[0082] See also Figure 3 The installation opening 10 is also connected to the guide groove 12, so that when the guide block 101 is installed in the installation opening 10, the guide block 101 is also connected to the guide surface 121. In this way, when the power output end of the connecting arm is in the guide groove 12, it can be against the top of the guide block 101, and under the drive of the driving assembly, it can move up and down along the guide surface 121, wherein the guide block 101 plays a supporting role.

[0083] In addition, see Figure 5 A stop block 103 is provided on the side of the nut 18 away from the connecting arm, and correspondingly, a notch for installing the stop block 103 is provided on the chassis housing 1. A slide rail is also provided on the stop block 103, and a slider 102 is also provided on the side of the nut 18 facing the stop block 103, and the slider 102 is slidably connected to the slide rail on the stop block 103. Thus, the two sides of the nut 18 are guided to slide by the guide block 101 and the stop block 103 respectively, so that the nut 18 can slide more smoothly and more labor-savingly when sliding linearly.

[0084] In this embodiment, a control module is also installed in the chassis housing 1, and the motor 16 is electrically connected to the control module. The signal module 14 is also electrically connected to the control module. The motor 16 and the screw 17 are coaxially arranged, and the control module also extends along the axial direction of the screw 17. The control module, the screw 17, and the motor 16 are arranged side by side, and do not occupy the space in the height direction of the chassis housing 1, thereby making the height of the chassis housing 1 can be designed to be smaller, realizing a flat and ultra-thin design of the chassis.

[0085] In this embodiment, refer to Figure 6 and Figure 7A key hole 19 is provided on the chassis shell 1 , an unlocking groove 115 is provided on the screw rod 17 , and the unlocking groove 115 is arranged opposite to the key hole 19 .

[0086] Based on this structure, when the motor 16 has a problem or the transmission fails and cannot drive the flap 21 to rise or fall, the key can be inserted into the unlocking slot 115 at one end of the screw 17 through the keyhole 19. By turning the key, the screw 17 can be rotated forward or reversed, thereby realizing manual raising or lowering of the flap 21 and enhancing the versatility of the chassis shell 1.

[0087] In this embodiment, refer to Figure 2 and Figure 6 A mounting hole 11 is provided on the side of the chassis housing 1, and a signal module 14 of the parking lock is installed in the mounting hole 11.

[0088] On the basis of this structure, the mounting hole 11 passes through one side of the chassis shell 1, and the mounting hole 11 is preferably set on a side of the chassis shell 1 away from the flap 21. It should be noted that in the prior art, the signal module 14 is set on the top of the chassis. Although this can prevent other components from interfering with the signal of the signal module 14, it will also cause the height of the chassis to increase. Therefore, the present application sets the signal module 14 on the side of the chassis, and sets it on the side of the chassis away from the flap 21, which can prevent the flap 21 or other components from interfering with the signal module 14, and can further reduce the height of the chassis. Among them, the signal module 14 of the parking lock can specifically be a 4G antenna module, which can connect the parking lock to the Internet and / or the terminal product.

[0089] In this embodiment, a speaker hole 111 is provided on the side of the chassis shell 1, and a speaker 112 of the parking lock is also provided inside the chassis shell 1, and the generating part of the speaker 112 of the parking lock faces the speaker hole 111. The speaker hole 111 is provided on the side of the chassis shell 1, which can effectively prevent the speaker hole 111 from being blocked by foreign objects such as sand and gravel, and enhances the versatility of the chassis shell 1.

[0090] Among them, the speaker hole 111 is arranged on a side surface of the chassis shell 1 away from the flap 21, and preferably, the speaker holes 111 are arranged at both ends of the side surface, and the end surfaces of the chassis shell 1 are also provided with speaker holes 111, that is, the two corners of the chassis shell 1 away from the flap 21 are respectively provided with a group of speaker holes 111. Among them, the speaker 112 of the parking lock is at least facing a group of speaker holes 111. While the chassis shell 1 protects the speaker 112 components, the sound of the speaker 112 can also penetrate the chassis shell 1 and be transmitted to the outside. In addition, since a group of speaker holes 111 are provided at the two corners of the chassis shell 1 away from the flap 21, when the internal components of the chassis shell 1 are reasonably arranged, the speaker 112 can be installed at any position of the two corners of the chassis shell 1, which significantly improves the versatility of the chassis shell 1.

[0091] In this embodiment, see Figure 4 The top surface of the chassis shell 1 is provided with a scanning area 113 for setting a charging code, thereby enhancing the versatility of the chassis shell 1.

[0092] When in use, a sticker or display board printed with the payment code can be pasted on the scanning area 113 through an adhesive layer or fixed by screws. After the car owner scans the code and pays the parking fee, the flap 21 can be flipped toward the ground and unlocked to release the lock on the parking space, and the car owner can drive the vehicle out of the parking space.

[0093] Among them, after the vehicle is parked, the chassis shell 1 is usually located on the outside of the vehicle, so the scanning area 113 is set on the top surface of the chassis shell 1, which is convenient for the car owner to directly scan the code to pay without putting the mobile phone under the car.

[0094] In this embodiment, see Figure 1 A chamfer 114 is provided at the connection between the top surface of the chassis shell 1 and the side surface of the chassis shell 1 .

[0095] Specifically, the chamfer 114 makes the peripheral edge of the top surface of the chassis shell 1 tilt downward; the setting of the chamfer 114 can reduce the stress concentration at the intersection of the two surfaces of the chassis shell 1 and enhance the strength of the chassis shell 1. In addition, the chamfer 114 also prevents the chassis shell 1 from having sharp edges and corners that scratch car tires, etc.

[0096] In this embodiment, refer to Fig. 9 A reinforcing rib 13 is provided on the inner side of the chassis shell 1 .

[0097] Specifically, the reinforcing ribs 13 are arranged on the inner side of the top wall of the chassis shell 1 , which can enhance the strength of the pressure-bearing surface of the chassis shell 1 , reduce the deformation degree of the chassis shell 1 , and extend the service life of the chassis shell 1 .

[0098] Embodiment 2

[0099] This embodiment discloses a parking lock. Figures 6 to 8 , which includes the chassis, support base 24 and flap 21 in the first embodiment, wherein the flap 21 is rotatably connected to the support base 24 via a rotating shaft 23. In addition, a driving shaft 22 is provided on the flap 21, and the driving shaft 22 is rotatably connected to the power output end of the transmission member 15 in the chassis. The axis of the rotating shaft 23 is parallel to the axis of the driving shaft 22 and is spaced apart, and the power output end of the driving assembly drives the flap 21 to rotate around the rotating shaft 23 via the driving shaft 22.

[0100] On this structural basis, during assembly, the support base 24 can be fastened to the ground by screws or other fasteners, and the flap 21 can be rotatably connected to the support base 24 by the rotating shaft 23. Preferably, two support bases 24 are used to install the flap 21 on the ground along the length direction of the flap 21.

[0101] When the parking lock of the utility model is used, when the parking lock is applied to a paid parking space, when a vehicle enters the parking space, the parking lock automatically identifies and raises the flap 21 to restrict the movement of the vehicle. The flap 21 has a connection side and a movable side arranged on the opposite side of the connection side, and the connection side is hinged to the ground through a rotating shaft 23 or directly, so that the movable side of the flap 21 can rotate around the connection side.

[0102] When the flap 21 flips over, the driving assembly in the chassis starts, and the driving assembly drives the transmission member 15 to move. The transmission member 15 pushes the movable side of the flap 21 to rotate around the rotating shaft 23 through the driving shaft 22. The movable side of the flap 21 approaches or moves away from the ground during the rotation.

[0103] It should be noted that the transmission member 15 moves in the height direction during the transmission process, so the chassis shell 1 is provided with a guide groove 12, and the power output end of the transmission member 15 is located in the guide groove 12 and can slide in the guide groove 12. In addition, the opening of the guide groove 12 extends from the side of the chassis shell 1 to the top surface, so the power output end of the transmission member 15 can be connected with the outer drive shaft 22 through the opening of the side of the guide groove 12, or the drive shaft 22 extends into the guide groove 12 through the opening of the side of the guide groove 12 and connects with the power output end of the transmission member 15. At the same time, the power output end of the transmission member 15 can extend upward to the top surface of the chassis shell 1 through the opening at the top of the guide groove 12 to drive the flap 21 to flip and rise; that is, the movement of the power output end of the transmission member 15 in the height direction is not affected by the height of the chassis, so that the height of the chassis shell 1 can be set smaller when designing the chassis, so that when the chassis is installed on the ground, the height of the chassis will not affect the vehicle door opening, making the entire parking lock more flat and ultra-thin.

[0104] Among them, when the parking space is located outdoors and the ground is relatively uneven, the flap 21 can be directly installed on the ground through the support seat 24, which can overcome the installation inconvenience caused by the uneven terrain.

[0105] As a preferred embodiment, the parking lock further comprises a base 20, the flap 21 is rotatably connected to the base 20 via a rotating shaft 23, and the base 20 is locked on a relatively flat ground via fasteners such as screws. Specifically, the base 20 can be a bottom plate, and a support base 24 is mounted on the bottom plate via fasteners such as screws, see Figure 7 The flap 21 is rotationally connected to the support seat 24 through the rotating shaft 23, which includes two connection methods. One is that the rotating shaft 23 is relatively fixedly connected to the flap 21, and the rotating shaft 23 is rotationally connected to the support seat 24. The other is that the rotating shaft 23 is rotationally connected to the flap 21, and the rotating shaft 23 is relatively fixedly connected to the support seat 24. Both methods can realize the rotation connection between the flap 21 and the support seat 24 through the rotating shaft 23.

[0106] Since the connection side of the flap 21 is rotatably connected to the base 20 via the rotation shaft 23, when the driving assembly drives the power input end of the transmission member 15 to move toward the power output end of the transmission member 15, the power output end of the transmission member 15 will push the movable end of the flap 21 away from the base 20 through the driving shaft 22, so that the flap 21 rotates around the rotation shaft 23 and rises. Conversely, when the driving assembly is reset and drives the power input end of the transmission member 15 to move away from the power output end of the transmission member 15, the power output end of the transmission member 15 will drive the movable end of the flap 21 to approach the base 20, so that the flap 21 rotates around the rotation shaft 23 and falls.

[0107] Thus, by setting the rotating shaft 23, one side of the flap 21 can be fixed on the base 20, and the other side of the flap 21 can be raised or lowered in the process of approaching or moving away from the base 20. Since the flap 21 can be attached to the base 20 after approaching the base 20, when the parking lock is in the unlocked state and the vehicle presses over the parking lock to enter or exit the parking space, the pressure on the flap 21 and the support seat 24 can be dispersed through the base 20, thereby improving the pressure bearing capacity of the support seat 24.

[0108] In addition, when the parking lock includes a base 20, the driving component or control component in the chassis can also be directly installed on the base 20. The driving component and rotating parts of the parking lock can be integrated on the base 20, which facilitates the overall installation of the parking lock on the parking space and saves installation time.

[0109] In this embodiment, refer to Figure 8 The axis of the rotating shaft 23 is parallel to the axis of the driving shaft 22 and is arranged at a certain distance.

[0110] When the driving shaft 22 is subjected to the force transmitted by the transmission member 15, the driving shaft 22 will rotate around the rotating shaft 23 together with the flap 21. When the axis of the rotating shaft 23 is parallel to the axis of the driving shaft 22 and the interval therebetween, it can be ensured that there is a certain force arm between the driving shaft 22 and the rotating shaft 23. When the transmission member 15 acts on the driving shaft 22 to drive the flap 21 to rotate around the rotating shaft 23, the rotation of the flap 21 is more labor-saving, that is, the output force of the transmission member 15 is smaller, and then the output power of the motor 16 can be designed to be smaller, thereby saving costs.

[0111] In this embodiment, the rotating shaft 23 is arranged on one side of the flap 21, and the driving shaft 22 is spaced apart from the rotating shaft 23. The axial direction of the rotating shaft 23 is the length direction of the flap 21, and the driving shaft 22 and the rotating shaft 23 are spaced apart in the width direction of the flap 21, and the spacing between the driving shaft 22 and the rotating shaft 23 is less than half of the width value of the flap 21. When the transmission member 15 acts on the driving shaft 22 to drive the flap 21 to rotate around the rotating shaft 23, the distance that the driving shaft 22 moves up is the spacing between the driving shaft 22 and the rotating shaft 23, and the spacing between the driving shaft 22 and the rotating shaft 23 is less than half of the width value of the flap 21, which will not make the distance that the driving shaft 22 moves up too high, and can also make the output force of the transmission member 15 as small as possible, that is, while realizing the flat and ultra-thin parking lock, it can also realize that the motor 16 can output a large torsional torque with low power.

[0112] In this way, the flap 21 can rotate around the rotating shaft 23 driven by the driving shaft 22 and the transmission member 15, thereby achieving lifting or lowering. The driving shaft 22 is arranged at a distance from the rotating shaft 23, and the larger the distance between the driving shaft 22 and the rotating shaft 23, the longer the force arm is according to the lever principle, and the more labor is saved, so the driving shaft 22 can drive the flap 21 to rotate around the rotating shaft 23 with relatively less labor.

[0113] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
