Description

Technical Field

[0001] The invention relates to the field of bicycle parking equipment, and in particular to a locking mechanism for bicycle parking equipment. Background Art

[0002] Bicycles are two-wheeled common means of transportation, green and environmentally friendly. Bicycles are parked randomly, occupying space, making it very inconvenient to use bicycles, affecting traffic and the city appearance. In order to solve this problem, bicycle parking racks have emerged. In order to further save space, vertical lifting bicycle parking racks have emerged.

[0003] A driving assembly is arranged in the bicycle parking device to drive the parking rack to move between the upper and lower levels. When the parking rack is not parked with a bicycle, it is in a light-loaded state, and when the parking rack is placed with a bicycle, it is in a heavy-loaded state. In order to allow the user to save effort when pulling the parking rack to switch between the upper and lower levels, a switching mechanism needs to be arranged. In the light-loaded state, the pulling force of the driving assembly is adapted to the gravity of the parking rack, and in the heavy-loaded state, the pulling force of the driving assembly is adapted to the sum of the gravity of the parking rack and the bicycle. In addition, the space for the pillars of the bicycle parking device is limited. How to compactly and reliably arrange this switching mechanism is a problem that needs to be solved urgently. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a locking mechanism for a bicycle parking device which has a compact and reliable structure and can switch the lifting pulling force between a light-load state and a heavy-load state of the parking rack.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a locking mechanism for a bicycle parking device, the bicycle parking device comprises a pillar, a heavy-load hanging plate and a light-load hanging rod are arranged in the pillar, the heavy-load hanging plate is connected to a heavy-load spring group, the light-load hanging rod is connected to a light-load spring group, the locking mechanism comprises a movable locking block, a fixed locking block, and a driving locking block, the movable locking block is arranged on the heavy-load hanging plate and can extend relative to the heavy-load hanging plate and limit with the fixed locking block, or retract and release the limit with the fixed locking block,

[0006] The fixed locking block is fixedly arranged on the inner wall of the pillar, and the driving locking block is arranged on the inner wall of the pillar and is arranged above the fixed locking block. In a light-load state, the movable locking block extends relative to the heavy-loaded hanger plate and is limited by the fixed locking block to limit the heavy-loaded hanger plate from moving downward. In a heavy-load state, the parking rack is pressed downward, and when the heavy-loaded hanger plate moves upward, the driving locking block drives the movable locking block to retract relative to the heavy-loaded hanger plate, and the limit of the movable locking block and the fixed locking block is released, and the heavy-loaded hanger plate moves downward.

[0007] Compared with the prior art, the advantages of the present invention are:

[0008] In the light-load state, the heavy-load hanger plate is restricted from moving downward by the locking mechanism, and the heavy-load spring group cannot pull the heavy-load hanger plate downward and thus cannot pull the parking rack upward. The light-load spring group pulls the parking rack upward through the light-load hanger rod; in the heavy-load state, the parking rack is pressed downward, and after the heavy-load hanger plate moves upward, the driving lock block drives the movable lock block to retract relative to the heavy-load hanger plate, and the limit of the movable lock block and the fixed lock block is released. The heavy-load spring group and the light-load spring group jointly drive the parking rack to rise, making it easier for the user to operate the parking rack to move between the upper and lower floors. The heavy-load hanger plate and the light-load hanger rod are both arranged in the pillar, and the locking mechanism is arranged on the upper part of the heavy-load hanger plate, and moves between the heavy-load hanger plate and the pillar, and the structure is more compact.

[0011] In the overload state, the parking rack is pressed, and the movable lock block moves upward with the overload hanging plate, and the movable lock block drives the driving lock block to move upward until the driving lock block abuts against the limit block, and the movable lock block continues to move upward, and the driving angle abuts against the side wall of the driven angle and drives the movable lock block to retract into the overload hanging plate.

[0012] The movable locking block moves to the upper part of the driving locking block, and the driving locking block moves downward with gravity until it is against the fixed locking block, and the driven angle is against the side wall of the driving angle, and the pressing of the parking rack is cancelled. The heavy-load spring group pulls the heavy-load hanging plate downward, and the side wall of the driving angle is against the lower end surface of the driven angle and drives the movable locking block to retract the heavy-load hanging plate, and the movable locking block moves downward and passes over the fixed locking block.

[0013] Preferably, a second driving surface is provided at the lower portion of the fixed locking block, and when the movable locking block moves upward from below the fixed locking block, the second driving surface drives the driven angle to retract the movable locking block into the heavy-load hanging plate.

DETAILED DESCRIPTION

[0027] like Figures 1 to 7 As shown,

[0028] A bicycle parking device comprises a support column 1 and a parking rack 2.

[0029] The support 1 is arranged vertically, the parking frame 2 is arranged horizontally and the inner end is arranged on the support 1 through a sliding seat 2.1 to be vertically slidable. The lower part of the parking frame 2 is provided with a switch assembly 3, which limits the sliding seat 2.1 and the support 1.

[0030] A driving assembly 4, a pulley assembly 5, and a steel wire rope 6 are arranged in the pillar 1. The driving assembly 4 includes a light-loaded suspension rod 4.1, a heavy-loaded suspension plate 4.2, a locking mechanism 4.3, a light-loaded spring group 4.4, and a heavy-loaded spring group 4.5. The light-loaded suspension rod 4.1 is arranged through the heavy-loaded suspension plate 4.2, and the heavy-loaded suspension plate 4.2 can drive the light-loaded suspension rod 4.1 to move downward, and the light-loaded suspension rod 4.1 can drive the heavy-loaded suspension plate 4.2 to move upward.

[0031] The light-load spring group 4.4 is connected to the light-load suspension rod 4.1 and elastically drives the light-load suspension rod 4.1 to move downward. The heavy-load spring group 4.5 is connected to the heavy-load suspension plate 4.2 and elastically drives the heavy-load suspension plate 4.2 to move downward. The locking mechanism 4.3 is arranged between the heavy-load suspension plate 4.2 and the support 1 and is used to limit the heavy-load suspension plate 4.2 to move downward relative to the support 1.

[0032] The light load suspension rod 4.1 is connected to the pulley assembly 5, and the wire rope 6 passes through the pulley assembly 5 and is connected to the sliding seat 2.1.

[0033] When the parking rack 2 is in a light-load state, that is, when no bicycle is placed on the parking rack 2, the heavy-load hanging plate 4.2 is limited by the locking mechanism 4.3 and the support 1, the switch assembly 3 is unlocked, and the light-load spring group 4.4 pulls the light-load hanging rod 4.1 downward and pulls the parking rack 2 upward through the wire rope 6.

[0034] The parking rack 2 is in a heavy-load state, that is, after the parking rack 2 is placed with a bicycle, the bicycle is pressed and the parking rack 2 is driven to move downward, the light-loaded hanging rod 4.1 pulls the heavy-loaded hanging plate 4.2 upward and drives the locking mechanism 4.3 and the pillar 1 to release the limit, the pressing of the parking rack 2 is cancelled, the switch assembly 3 is unlocked, the heavy-loaded spring group 4.5 pulls the heavy-loaded hanging plate 4.2 downward and at the same time the light-loaded spring group 4.4 pulls the light-loaded hanging rod 4.1 downward, and the heavy-loaded spring group 4.5 and the light-loaded spring group 4.4 simultaneously pull the parking rack 2 upward through the wire rope 6.

[0035] The inner end of the parking frame 2 is slidably set on the outside of the pillar 1 through a sliding seat 2.1. A roller is provided on the sliding seat 2.1. A track cooperating with the roller is provided on the outside of the pillar 1. The sliding cooperation between the roller and the track is the prior art. The switch assembly 3 is set at the outer end of the parking frame 2. The limit between the sliding seat 2.1 and the pillar 1 is released by pulling the switch assembly 3. An installation cavity is provided inside the pillar 1, and the drive assembly 4, the pulley assembly 5, and the wire rope 6 are all set in the installation cavity.

[0036] Among them, the switch assembly 3 includes a handle switch arranged at the outer end of the parking frame 2, a switch lock tongue arranged at the inner end of the parking frame 2, a connecting rod connecting the handle switch and the switch lock tongue, and a switch lock block arranged in the pillar 1 for cooperating with the switch lock tongue. When the handle switch is pressed, the connecting rod pulls the switch lock tongue and the switch lock block to unlock. The switch assembly 3 can select relevant existing technologies, which will not be repeated here.

[0037] The outer peripheral protrusion of the light-loaded hanger rod 4.1 is provided with a protrusion 4.1.1, and the upper end surface of the protrusion 4.1.1 is abutted against the lower end surface of the heavy-loaded hanger plate 4.2. When the light-loaded hanger rod 4.1 moves downward relative to the heavy-loaded hanger plate 4.2 or the heavy-loaded hanger plate 4.2 moves upward relative to the light-loaded hanger rod 4.1, the heavy-loaded hanger plate 4.2 and the light-loaded hanger rod 4.1 are not limited. When the light-loaded hanger rod 4.1 moves upward relative to the heavy-loaded hanger plate 4.2 or the heavy-loaded hanger plate 4.2 moves downward relative to the light-loaded hanger rod 4.1, the upper end surface of the protrusion 4.1.1 is abutted against the lower end surface of the heavy-loaded hanger plate 4.2, and the heavy-loaded hanger plate 4.2 and the light-loaded hanger rod 4.1 are limited at this time. Therefore, the heavy-loaded hanger plate 4.2 can drive the light-loaded hanger rod 4.1 to move downward, and the light-loaded hanger rod 4.1 can drive the heavy-loaded hanger plate 4.2 to move upward.

[0038] The locking mechanism 4.3 includes a movable locking block 4.3.1, a fixed locking block 4.3.2, and a driving locking block 4.3.3. The movable locking block 4.3.1 is arranged on the heavy-load hanging plate 4.2 and can extend relative to the heavy-load hanging plate 4.2 and limit with the fixed locking block 4.3.2, or retract and release the limit with the fixed locking block 4.3.2.

[0039] The fixed locking block 4.3.2 is fixedly set on the inner wall of the pillar 1, and the driving locking block 4.3.3 is set on the inner wall of the pillar 1 and is set above the fixed locking block 4.3.2. In the light-load state, the movable locking block 4.3.1 extends relative to the heavy-loaded hanger plate 4.2 and limits the heavy-loaded hanger plate 4.2 with the fixed locking block 4.3.2 to limit the heavy-loaded hanger plate 4.2 from moving downward. In the heavy-load state, the parking rack 2 is pressed downward. When the heavy-loaded hanger plate 4.2 moves upward, the driving locking block 4.3.3 drives the movable locking block 4.3.1 to retract relative to the heavy-loaded hanger plate 4.2, and the limit of the movable locking block 4.3.1 and the fixed locking block 4.3.2 is released, and the heavy-loaded hanger plate 4.2 moves downward.

[0040] A limit block 4.3.4 is provided above the driving lock block 4.3.3. The side wall of the driving lock block 4.3.3 close to the movable lock block 4.3.1 is a driving angle 4.3.3.1 set obliquely downward. The side wall of the movable lock block 4.3.1 corresponding to the driving angle 4.3.3.1 is provided with a driven angle 4.3.1.1 set obliquely downward.

[0041] When the parking rack 2 is in a light-load state, the driving angle 4.3.3.1 is located above the driven angle 4.3.1.1, that is, the driving angle 4.3.3.1 abuts against the side wall of the driven angle 4.3.1.1, and the lower end surface of the driven angle 4.3.1.1 abuts against the upper end surface of the fixed locking block 4.3.2. The heavy-load hanging plate 4.2 is restricted from moving downward by the fixed locking block 4.3.2.

[0042] When the parking rack 2 is in the overload state, the parking rack 2 is pressed, and the movable lock block 4.3.1 moves upward with the overload hanging plate 4.2, and the movable lock block 4.3.1 drives the driving lock block 4.3.3 to move upward until the driving lock block 4.3.3 abuts against the limit block 4.3.4, and the movable lock block 4.3.1 continues to move upward, and the driving angle 4.3.3.1 abuts against the side wall of the driven angle 4.3.1.1 and drives the movable lock block 4.3.1 to retract into the overload hanging plate 4.2.

[0043] The movable locking block 4.3.1 moves to the upper part of the driving locking block 4.3.3, and the driving locking block 4.3.3 moves downward with gravity until it is against the fixed locking block 4.3.2, and the driven angle 4.3.1.1 is against the side wall of the driving angle 4.3.3.1, and the pressing of the parking rack 2 is cancelled. The heavy-load spring group 4.5 pulls the heavy-load hanging plate 4.2 downward, and the side wall of the driving angle 4.3.3.1 is against the lower end surface of the driven angle 4.3.1.1 and drives the movable locking block 4.3.1 to retract the heavy-load hanging plate 4.2, and the movable locking block 4.3.1 moves downward and passes over the fixed locking block 4.3.2.

[0044] A second driving surface 4.3.2.1 is provided at the lower part of the fixed locking block 4.3.2. When the movable locking block 4.3.1 moves upward from the lower part of the fixed locking block 4.3.2, the second driving surface 4.3.2.1 drives the driven angle 4.3.1.1 to make the movable locking block 4.3.1 retract the heavy-load hanging plate 4.2.

[0045] There are two locking mechanisms 4.3, which are respectively arranged on both sides of the upper part of the heavy-load hanging plate 4.2. A transversely arranged locking block spring 4.3.6 is arranged between the two movable locking blocks 4.3.1. The locking block spring 4.3.6 elastically drives the movable locking block 4.3.1 to extend out of the heavy-load hanging plate 4.2.

[0046] The principle of the locking mechanism 4.3 is:

[0047] Under light load condition, Figures 2-3 As shown, no bicycle is placed on the parking rack 2, and the driven angle 4.3.1.1 of the movable lock block 4.3.1 is between the driving lock block 4.3.3 and the fixed lock block 4.3.2. The lower end surface of the movable lock block 4.3.1 is against the upper end surface of the fixed lock block 4.3.2. The fixed lock block 4.3.2 limits the heavy-load hanger plate 4.2 to move downward, and the light-load hanger rod 4.1 can move downward relative to the heavy-load hanger plate 4.2. At this time, the light-load spring group 4.4 participates in the lifting of the sliding seat 2.1, while the heavy-load spring group 4.5 does not participate in the lifting of the sliding seat 2.1. The switch assembly 3 is unlocked, and the light-load spring group 4.4 can drive the parking rack 2 from the lower layer to the upper layer.

[0048] In heavy load state, such as Figure 4 As shown, push the bicycle into the parking rack 2. After the bicycle is completely in the parking rack 2, the parking rack 2 will drive the heavy-load hanging plate 4.2 to move downward a certain distance due to the gravity of the bicycle. At this time, the locking mechanism 4.3 is as shown in FIG. Figure 5As shown, the sliding seat 2.1 pulls the wire rope 6 downwards and at the same time the wire rope 6 pulls the light-loaded suspension rod 4.1 upwards through the pulley block, and the light-loaded suspension rod 4.1 drives the heavy-loaded suspension plate 4.2 to move upwards, and the lower end surface of the movable locking block 4.3.1 is separated from the lower end surface of the fixed locking block 4.3.2. At this time, the movable locking block 4.3.1 drives the driving locking block 4.3.3 to move upwards until the driving locking block 4.3.3 is against the limit block 4.3.4. At this time, if the user directly presses the bicycle, the lower end surface of the movable locking block 4.3.1 will still be against the upper end surface of the fixed locking block 4.3.2, and the heavy-loaded suspension plate 4.2 cannot move downwards;

[0049] The bicycle is placed in the parking rack 2, and the user presses the bicycle, and the parking rack 2 continues to move downward. Figure 6 As shown, at this time, the heavy-loaded hanging plate 4.2 continues to move upward, and the driving angle 4.3.3.1 of the driving lock block 4.3.3 pushes the driven surface of the movable lock block 4.3.1, and the movable lock block 4.3.1 retracts the heavy-loaded hanging plate 4.2 until the movable lock block 4.3.1 moves above the driving lock block 4.3.3, and the driving lock block 4.3.3 moves downward with gravity, and the side wall of the driving angle 4.3.3.1 is against the lower end surface of the driven angle 4.3.1.1, and the pressure on the bicycle is released. The heavy-loaded spring group 4.5 pulls the heavy-loaded hanging plate 4.2 downward. Since the distance a from the side wall of the driving lock block 4.3.3 close to the movable lock block 4.3.1 to the center of the heavy-loaded hanging plate 4.2 is, the fixed lock block 4.3.2 close to the movable lock block The distance between the side wall of the dynamic lock block 4.3.1 and the center of the heavy-load hanger plate 4.2 is b, and a is greater than b, that is, the side wall of the driving lock block 4.3.3 protrudes from the side wall of the fixed lock block 4.3.2. Therefore, when the dynamic lock block 4.3.1 moves downward with the heavy-load hanger plate 4.2, it can be directly moved from the side wall of the driving angle 4.3.3.1 to the side wall of the fixed lock block 4.3.2, and then move downward. During the process, the heavy-load hanger plate 4.2 is always pulled by the heavy-load spring group 4.5, and the heavy-load hanger plate 4.2 also synchronously pulls the light-load hanger rod 4.1 downward. At this time, the heavy-load spring group 4.5 and the light-load spring group 4.4 simultaneously participate in lifting the parking rack 2. When the parking rack 2 moves to the upper layer, the locking mechanism 4.3 is as shown in FIG. Figure 7 shown.

[0050] When the parking rack 2 is reset from the upper layer to the lower layer of the pillar 1, the heavy-loaded hanging plate 4.2 moves upward from the bottom of the fixed locking block 4.3.2, and the second driving surface 4.3.2.1 at the bottom of the fixed locking block 4.3.2 drives the movable locking block 4.3.1 to retract the heavy-loaded hanging plate 4.2. When the movable locking block 4.3.1 passes the side wall of the fixed locking block 4.3.2 and the driven surface of the movable locking block 4.3.1 abuts against the driving angle 4.3.3.1 of the driving locking block 4.3.3, the movable locking block 4.3.1 extends relative to the heavy-loaded hanging plate 4.2, and the driving locking block 4.3.3 is pushed upward, and the lower end surface of the movable locking block 4.3.1 abuts against the upper end surface of the fixed locking block 4.3.2 to complete the reset.

[0051] Among them, a vertical movable rod 4.3.5 is provided on the upper part of the fixed locking block 4.3.2, and a movable hole is provided in the center of the driving locking block 4.3.3 to cooperate with the movable rod 4.3.5. The movable rod 4.3.5 cooperates with the movable hole, so that the driving locking block 4.3.3 moves above the fixed locking block 4.3.2 in a guided manner.

[0052] Among them, the driving angle 4.3.3.1 is extended downwardly and is provided with a stopper 4.3.3.2. When the driving lock block 4.3.3 abuts against the fixed lock block 4.3.2, the stopper 4.3.3.2 is located on the outer side of the side wall of the fixed lock block 4.3.2. When the heavy-loaded hanging plate 4.2 moves downward, the stopper 4.3.3.2 can prevent the movable lock block 4.3.1 from being stuck into the gap between the driving lock block 4.3.3 and the fixed lock block 4.3.2, thereby ensuring that the movable lock block 4.3.1 moves downward smoothly; when the heavy-loaded hanging plate 4.2 moves upward, the movable lock block 4.3.1 abuts against the stopper 4.3.3.2 and drives the driving lock block 4.3.3 to move upward, so that the movable lock block 4.3.1 extends between the driving lock block 4.3.3 and the fixed lock block 4.3.2, thereby returning to its initial state.

[0053] Among them, the two movable locking blocks 4.3.1 include a first movable block 4.3.1.2 and a second movable block 4.3.1.3. The inner end of the first movable block 4.3.1.2 is provided with a first sliding portion 4.3.1.21, a first mounting column 4.3.1.22, and a first sliding groove 4.3.1.23. The inner end of the second movable block 4.3.1.3 is provided with a second sliding portion 4.3.1.31, a second mounting column 4.3.1.32, and a second sliding groove 4.3.1.33. The first sliding portion 4.3.1.21 is arranged at the upper part of the first sliding groove 4.3.1.23, the first mounting column 4.3.1.22 is arranged at the inner end of the first sliding portion 4.3.1.21, the second sliding portion 4.3.1.31 is arranged at the lower part of the second sliding groove 4.3.1.33, the second mounting column 4.3.1.32 is arranged at the inner end of the second sliding portion 4.3.1.31, and the first sliding portion The movable part 4.3.1.21 slides in the second sliding groove 4.3.1.33, and the second sliding part 4.3.1.31 slides in the first sliding groove 4.3.1.23. The locking block spring 4.3.6 is a tension spring arranged between the first mounting column 4.3.1.22 and the second mounting column 4.3.1.32. By setting the above structure, the two movable locking blocks 4.3.1 can be made more compact in height, and the first sliding groove 4.3.1.23 guides the sliding of the second sliding part 4.3.1.31, and the second sliding groove 4.3.1.33 guides the sliding of the first sliding part 4.3.1.21, so that the sliding fit is more accurate. At the same time, the locking block spring 4.3.6 is installed between the first mounting column 4.3.1.22 and the second mounting column 4.3.1.32, and is arranged on the outside of the movable locking block 4.3.1, which is more convenient for installation and disassembly and replacement.

[0054] The driving assembly 4 further comprises a spring base 4.6 arranged at the bottom of the pillar 1, the heavy-load spring group 4.5 is a plurality of tension springs arranged between the heavy-load hanger plate 4.2 and the spring base 4.6, and the light-load spring group 4.4 is a plurality of tension springs arranged between the light-load hanger rod 4.1 and the spring base 4.6.

[0055] The tension of the light-load spring group 4.4 is used to match the gravity of the parking rack 2 and the sliding seat 2.1, so that the user can save more effort when operating the parking rack 2 in a light-load state to move up. Generally, one tension spring can be selected to achieve this. The tension of the heavy-load spring group 4.5 is used to match the gravity of the bicycle, so that the user can save more effort when operating the parking rack 2 in a heavy-load state to move up. Generally, 2 to 6 tension springs can be selected to achieve this.
