Description

Technical Field

[0001] This application relates to the field of bicycles, and more particularly to a protective device for the seat cushion of a shared bicycle. Background Technology

[0002] In current technology, shared bicycles are mostly parked in the open, with the bicycle seats exposed. In the hot summer, the seats get hot from the sun; on rainy days or when city sanitation workers spray water, the seats get wet and leave water stains; on windy and sandy days, the seats get covered in dust. Before riding, users often wipe the seats with tissues or put them in plastic bags, and some even throw the soiled tissues directly on the ground or in the bicycle basket, or leave the plastic bags directly on the seats. This not only affects the riding experience but also the appearance of the city and increases the workload of sanitation workers. Shared bicycles with seats that are too dirty or too hot from the sun are often left unused, resulting in a decrease in the utilization rate of shared bicycles.

[0003] Most existing bicycle saddle covers are made of fabric or leather and are sold in a standardized manner on the market. These covers are separate from the bicycle and have nowhere to be stored after being removed while riding, which is inconvenient for promotion in the shared bicycle industry. Other covers are integrated with the frame and are fixed to it, making it inconvenient to adjust the seat height, which directly affects the user experience of shared bicycles. These covers are in direct contact with the upper surface of the seat and have poor heat insulation when exposed to the sun, which directly affects the riding experience.

[0004] In the past two years, shared bicycles have promoted the use of "cooling mats" in the summer. The mats do not need to be removed while riding and have a certain cooling effect. However, when exposed to high temperatures, the surface temperature can reach over 50°C, resulting in poor heat insulation. They are not waterproof and can get wet after wear and tear, which does not improve the riding experience. The mats are attached to the seat with a rope, which makes them easy to remove and thus susceptible to theft. They are also prone to wear and tear and need to be replaced frequently, resulting in high operating costs.

[0005] Existing patent CN209938803U relates to a bicycle saddle protector, but the saddle and the protector are separate, requiring the protector to be removed from the bicycle frame and installed around the bicycle saddle, which is inconvenient and time-consuming. Existing patent CN210734365U relates to a saddle protection device, which includes a horizontally set baffle. The baffle is moved above the saddle or retracted from the saddle by a telescopic rod, so that the baffle can provide sun or rain protection for the saddle. However, the baffle is only a flat plate and does not fit the saddle very well, so the effect of shielding and protecting is very limited.

[0006] Existing patent CN215323011U relates to a bicycle seat cover, including a cover and a miniature electronic lock. However, its opening / closing action relies on the shared bicycle control logic and power supply module. Currently deployed shared bicycles do not have extra power supply interfaces and control communication signal lines at the seat. If the seat cover of patent CN215323011U is to be installed in existing shared bicycles, the entire bicycle needs to be transported to a designated factory and professional technicians need to run conduits and wires. The modification and implementation cost is extremely high, and the production cost of the device is also relatively high. The existing stock of shared bicycles on the market is already saturated, making it even more inconvenient to promote and apply.

[0007] Bike-sharing operators know that improving user experience is the only way to increase bike utilization. There is an urgent need for a sun and rain protection device that can both improve the user experience of shared bikes and be easy to implement and promote. Summary of the Invention

[0008] This application discloses a protective device for a shared bicycle seat cushion, the protective device comprising:

[0009] Protective cover (100) and delayed flip cover assembly (200); wherein:

[0010] The protective cover includes: a cover (101), a side (102), and a support plate (103); one end of the support plate (103) is connected to one side of the cover (101), and the included angle between the cover (101) and the support plate (103) is α°, where α is in the range of 90°≤α≤140°; under the vertical support of the support plate (103), the cover (101) can maintain a certain gap with the cushion (1), increasing the sun protection and heat insulation effect, where the height of the gap is H mm, and H is in the range of 5 mm≤H≤30 mm; the protective cover The side (102) of (100) has a combination of curved and inclined surfaces to enhance the adaptability and coverage of the protective cover (100); the protective cover (100) is made of plastic, and the cover (101), the side (102) and the support plate (103) are bonded together or integrally injection molded; the side (102) is soft and can eliminate the influence of lateral external forces; the cover (101) and the support plate (103) are hard and tough, which is sufficient to support the flipping force on the protective cover (100) and its own weight; a heat insulation layer can also be provided on the surface of the protective cover (100).

[0011] The delayed flip-top device assembly includes: a housing (201), a central axle (202), a power spring (203), a main gear (204), a driven gear (205), an escapement mechanism, and a control mechanism; the housing (201) is fixedly installed on the lower surface of the base plate (4) of the seat cushion (1), the housing (201) includes a front wall, a rear wall, a left wall, a right wall, an upper wall, and a lower wall, and the housing (201) is provided with one or more partition strips (20103), the front wall of the housing (201) is close to the tail of the seat cushion (1) and directly opposite the support plate (103), and the left wall, right wall, and partition strips (20103) of the housing (201) are each provided with a shaft hole; the central axle (202) passes through the... The shaft holes on the left wall of the box body (201), the shaft holes of the partition strip (20103), the shaft hole of the main gear (204), and the shaft hole on the right wall of the box body (201) are rotatably connected to the left and right walls of the box body (201). To prevent the central wheel shaft (202) from moving left and right, a retaining ring (20205) is provided on the central wheel shaft (202). To reduce the rotational friction of the central wheel shaft (202), a bearing (216) can also be provided in the shaft hole of the box body (201). The central wheel shaft (202) is rotatably connected to the bearing (216). The central wheel shaft (202) is connected to the support plate (103) so that the central wheel shaft (202) can drive the protective cover (100) to flip.

[0012] The escapement mechanism includes an escape wheel (206) and a balance wheel (207). The escape wheel (206) is configured as a double-gear, and the large gear of the escape wheel (206) is configured as a helical gear (20601). The balance wheel (207) is configured with two pinions (20701). The two ends of the central shaft of the driven gear (205), the central shaft of the escape wheel (206), and the central shaft of the balance wheel (207) are respectively located on the right wall of the housing (201) and the partition strip (20103). The master gear (204), the driven gear (205), and the... The escape wheels (206) are sequentially meshed, and the helical teeth (20601) of the escape wheels (206) and the locking pins (20701) of the balance wheel (207) are close to each other, so that the escape wheels (206) can only rotate in one direction. Alternatively, according to the process assembly requirements, the two ends of the central shaft of the driven gear (205), the central shaft of the escape wheels (206) and the central shaft of the balance wheel (207) can be respectively set on two left and right strips (219), and then the two strips (219) are embedded into the groove formed by the right wall of the box body (201) and the partition strip (20103).

[0013] The central axle (202) is equipped with a limiting pin (20201), the main gear (204) is equipped with a limiting pin (20401) and a limiting pin (20402), there is one or more driven gears (205), one of which is configured as a one-way transmission gear and the driven gear (205) is configured as a double-layer gear; the power spring (203) is mounted on the central axle (202), the power spring (203) is selected as a torsion spring, and one end of the power spring (203) is mounted on the limiting pin (20402);

[0014] When the central axle (202) rotates counterclockwise, the limiting pins (20201 and 20401) abut against each other, causing the main gear (204) to rotate counterclockwise and the power spring (203) to tighten and store energy. The main gear (204) synchronously drives the driven gear (205) to rotate. Since the driven gear (205) is configured as a one-way transmission gear, it does not transmit power to the escape wheel (206) in this direction of rotation. The purpose of configuring the driven gear (205) as a one-way transmission gear is to meet the requirement that the escape wheel (206) can only rotate in one direction. When the tightened power spring (203) releases energy, the limiting pins (20402) drive the main gear (204) to rotate counterclockwise. 4) Rotating clockwise, the limiting pin (20401) and the limiting pin (20201) come into contact and drive the central wheel shaft (202) to rotate clockwise. The energy released by the power spring (203) and the power transmitted to the central wheel shaft (202) are sufficient to drive the protective cover (100) to flip upwards on the seat (1). The mutual transmission of the main gear (204), the driven gear (205) and the escape wheel (206) drives the helical tooth (20601) to periodically collide with the locking pin (20701) one tooth at a time, causing the balance wheel (207) to swing periodically, causing the power spring (203) to release energy in a delayed manner, thereby achieving the effect of automatically flipping the protective cover (100) in a delayed manner.

[0015] The control mechanism includes an electronic lock (208), a control board (209), a power supply module (210), and a sensor (211); the latch (20801) of the electronic lock (208) is directly opposite the balance wheel (207); during the energy release process of the power spring (203), the balance wheel (207) swings periodically. When the latch (20801) is close to the balance wheel (207), that is, when the two are in a engaged state, the balance wheel (207) is prevented from swinging by the latch (20801), which simultaneously prevents the sequentially connected escape wheel (206), the driven gear (205), and the master gear (204) from moving, thereby preventing the power spring (203) from releasing energy and pausing the flipping of the protective cover (100);

[0016] The sensor (211) transmits the collected information to the control board (209) to obtain two states: riding and non-riding. The control board (209) controls the latch (20801) and the swing wheel (207) to maintain two states: engaged and disengaged, according to the current riding / non-riding state of the shared bicycle. When the control board (209) obtains that the riding state has been switched to the non-riding state, the latch (20801) is deviated from the swing wheel (207), and the power spring (203) begins to release energy to achieve the effect of automatically flipping the protective cover (100).

[0017] The power supply module (210) supplies power to the control board (209). The battery of the power supply module (210) is configured as a rechargeable secondary battery. A solar charging panel (21001) is provided on the protective cover (100) or the delay flip cover assembly. The solar charging panel (21001) transmits the generated current to the power supply module (210) for charging, so as to achieve the self-sufficiency of the power required by the control mechanism.

[0018] In a preferred embodiment, a tray (301) can be configured as needed, the tray (301) being fixed under the base plate (4) of the cushion (1), the tray (301) being used to support the delayed flip cover assembly (200).

[0019] In a preferred embodiment, the box (201) is a semi-open structure, and the box (201) is fixed to the base plate (4) of the cushion (1) or the tray (301); the base plate (4) replaces the upper side wall of the box (201), or the tray (301) replaces the lower side wall of the box (201), and the two can be fixed to each other by riveting, gluing or integral injection molding.

[0020] In a preferred embodiment, the combination of the escapement mechanism is selected from one of the following groups: a combination of escape wheel (206) and balance wheel (207), or a combination of escape wheel (206), escape fork (212), hairspring (213) and balance wheel (207); both combinations of the escapement mechanism cause the balance wheel (207) to oscillate periodically by periodically colliding one tooth at a time.

[0021] In a preferred embodiment, the power spring (203) is selected from one of the following groups: torsion spring and spring, which stores energy by changing the elastic deformation of the torsion spring or spring through external force rotation, releases the energy of the torsion spring or spring when necessary, and cooperates with other components of the delay flip device group (200) to achieve the effect of delaying the flipping of the protective cover (100).

[0022] In a preferred embodiment, the delayed flip cover assembly is further configured with an assisting spring (214) and a limiting pin (20202). The limiting pin (20202) is disposed on the central axle (202), and the assisting spring (214) is disposed on the left or right end of the central axle (202). During operation, the assisting spring (214) and the power spring (203) synchronously tighten to store or release energy. When the assisting spring (214) and the power spring (203) synchronously release energy, they jointly drive the central axle (202) to rotate clockwise. The power transmitted by the assist spring (214) and the power spring (203) to the central axle (202) is sufficient to drive the protective cover (100) to flip over the seat cushion (1) until it covers the seat cushion (1); when the latch (20801) of the electronic lock (208) prevents the power spring (203) from releasing energy, the power of the assist spring (214) when releasing energy is insufficient to drive the protective cover (100) to flip, and the assist spring (214) stops releasing energy; the assist spring (214) is selected from one of the following groups: torsion spring and spring.

[0023] In a preferred embodiment, the support plate (103) of the protective cover (100) is provided with a shaft hole, and the shape of the central wheel axle (202) is selected from one of the following groups: "I", "C", double "U", double "L" and double "Z", and the central wheel axle (202) is connected to the support plate (103) through the shaft hole of the support plate (103).

[0024] In a preferred embodiment, the central axle (202) is further equipped with a limit pin (20203), a positioning pin (20204), and a positioning spring (215), the positioning spring (215) being selected from one of the following groups: torsion spring and clock spring; the shape of the central axle (202) is selected as "C", double "U" or double "Z", and the central axle (202) is rotatably connected to the support plate (103) through the lower end shaft hole of the support plate (103), and in The positioning pin (20204) and the positioning spring (215) work together to keep the support plate (103) and the center wheel axle (202) relatively fixedly connected. When the protective cover (100) covers the seat cushion (1), when the vertical external force causes the protective cover (100) to move downward, the center wheel axle (202) embedded in the lower end shaft hole of the support plate (103) moves downward at the same time to eliminate the influence of the vertical external force on the device.

[0025] In a preferred embodiment, the protective cover (100) has ventilation holes on its side (102) to achieve heat dissipation and water leakage functions. When the seat (1) is covered, the protective cover (100) and the upper surface of the seat (1) form a relatively closed narrow space. When the sunlight intensity is too high, the ventilation holes of the protective cover (100) allow the relatively closed narrow space to maintain ventilation and heat dissipation from the outside. When riding in the rain, the protective cover (100) is in a flip-top state, and the rainwater falling inside the protective cover (100) leaks out through the ventilation holes of the protective cover (100) to prevent water accumulation inside the protective cover (100).

[0026] In a preferred embodiment, the power supply of the control board (209) is selected from one of the following groups: power supply module (210) and shared bicycle battery (9).

[0027] In a preferred embodiment, the method by which the control board (209) collects information about the riding status is selected from one of the following groups: sensor (211) and the opening and closing lock command of the shared bicycle, wherein the sensor (211) is selected from one of the following groups: infrared sensor (21101), ultrasonic sensor (21102) and photoelectric sensor (21103).

[0028] In a preferred embodiment, the battery of the power supply module (210) is selected from one of the following groups: a replaceable primary battery and a rechargeable secondary battery; the energy storage source of the rechargeable battery is selected from one of the following groups or a combination thereof: a solar charging panel (21001) and a micro generator (21002).

[0029] In a preferred embodiment, the delayed flip cover assembly is further equipped with a bevel ring (217) and a touch switch (218). The bevel ring (217) and the touch switch (218) cooperate to obtain two states: the protective cover (100) covering the cushion (1) and the flip cover. When the protective cover (100) covers the cushion (1), the power supply to the control board (209) is stopped to save power. When the protective cover (100) is in the flip cover state, the power supply to the control board (209) is turned off.

[0030] The advantages of this invention are:

[0031] 1. By utilizing the energy storage and energy release delay of the power spring of the delayed flip cover device, the protective cover placed behind the seat cushion is automatically flipped to the top of the seat cushion in a short time, thus achieving the effect of automatically flipping the protective cover.

[0032] 2. The control board of this device automatically flips the protective cover and covers the seat when switching from riding mode to non-riding mode, thus achieving the effect of automatically covering the seat.

[0033] 3. The delayed opening action of the protective cover at the end of the ride makes this device more suitable for the alternating use of shared bicycles, avoiding disturbing the next rider by closing it instantly.

[0034] 4. This device features low energy consumption and self-sufficiency in electricity, achieving overall modularity and independence.

[0035] 5. The device is fixed to the bottom of the seat cushion and is integrated with the seat cushion, making it easy to adjust the height of the seat cushion;

[0036] 6. This device and the seat cushion are integrated, and existing shared bicycles can be replaced with seats equipped with this device anywhere. No professional technicians are required, and the implementation is convenient, quick, and low-cost, making it easy to promote and apply.

[0037] 7. This device has a simple structure and can be installed on existing shared bicycle seats, reducing waste and saving modification costs;

[0038] 8. This protective cover not only has sun protection and heat insulation effects, but also effectively resists wind and rain, keeping the shared bicycle seat clean for a long time.

[0039] The specification of this application contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which should be considered as described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description

[0078] like Figure 1 As shown, one end of the support plate 103 is connected to one side of the cover 101, and the included angle between the cover 101 and the support plate 103 is α°, where the value of α ranges from 90° to 140°. Figure 2 As shown, the side surface 102 has a combination of curved and inclined surfaces. The cover 101, the side surface 102 and the support plate 103 are bonded together or integrally injection molded. A heat insulation layer is provided on the surface of the protective cover 100.

[0079] like Figure 3 As shown, the box body 201 is fixedly installed on the lower surface of the base plate 4 of the cushion 1. The box body 201 includes a front wall, a rear wall, a left wall 20101, a right wall 20102, an upper wall, and a lower wall. The front wall of the box body 201 is located near the tail of the cushion 1 and is directly opposite the support plate 103. A partition strip 20103 is provided inside the box body 201. Each of the left wall 20101, the right wall 20102, and the partition strip 20103 of the box body 201 is provided with a shaft hole.

[0080] like Figure 4 As shown, the power spring 203, main gear 204, driven gear 205, escape wheel 206, balance wheel 207 and electronic lock 208 are disposed in the slot formed by the right wall 20102 and the partition bar 20103 of the housing 201;

[0081] like Figure 3As shown, the central axle 202 passes sequentially through the shaft hole on the left wall of the box 201, the shaft hole of the partition strip 20103, the shaft hole of the main gear 204, and the shaft hole on the right wall of the box 201, and is rotatably connected to the left and right walls of the box 201; a retaining ring 20205 is provided on the central axle 202 to prevent the central axle 202 from shifting left or right, or a retaining pin 20206 can be used instead of the retaining ring 20205; Figure 3 As shown, the shaft hole is located at the front of the front wall of the housing 201, as... Figure 5 As shown, the shaft hole can also be set behind the front wall of the housing 201 as needed;

[0082] like Figure 1 As shown, the central wheel axle 202 is fixed to the support plate 103, so that the central wheel axle 202 can drive the protective cover 100 to rotate.

[0083] like Figure 4 As shown, the driven gear 205 is configured as a unidirectional transmission gear and is a double-layer gear; the escape wheel 206 is configured as a double-layer gear; the large gear of the escape wheel 206 is configured as a helical gear 20601; and the balance wheel 207 is equipped with two locking pins 20701. The two ends of the central shaft 20501 of the driven gear 205, the central shaft 20602 of the escape wheel 206, and the central shaft 20702 of the balance wheel 207 are respectively set on the right wall 20102 and the partition bar 20103 of the housing 201. The master gear 204, the driven gear 205, and the escape wheel 206 are sequentially meshed with each other. The helical gear 20601 of the escape wheel 206 and the locking pins 20701 of the balance wheel 207 are close to each other, so that the escape wheel 206 can only rotate in one direction.

[0084] like Figure 6 As shown, the gear 205, escape wheel 206 and balance wheel 207 can also be first set between the two slats 219 as needed, and then the two slats 219 can be embedded into the groove formed by the right wall of the box 201 and the partition strip 20103.

[0085] like Figure 7 , 8 As shown, the central axle 202 is equipped with a limiting pin 20201, and the main gear 204 is equipped with a limiting pin 20401 and a limiting pin 20402, with the limiting pin 20201 and the limiting pin 20401 abutting against each other; the power spring 203 is selected as a torsion spring, and the power spring 203 is set on the central axle 202. One end of the power spring 203 abuts against the second limiting pin 20402 of the main gear of the main gear 204, and the other end of the power spring 203 is set on the wall of the box 201. The corresponding stiffness coefficient is adapted to the power spring 203 according to the actual power required by the flip protective cover 100.

[0086] like Figure 4As shown, the latch 20801 of the electronic lock 208 is directly opposite the balance wheel 207. During the energy release process of the power spring 203, the balance wheel 207 oscillates periodically. When the latch 20801 is close to the balance wheel 207, that is, when the two are in a engaged state, the balance wheel 207 is prevented from oscillating by the latch 20801, which simultaneously prevents the sequentially connected escape wheel 206, driven gear 205 and main gear 204 from moving, thereby preventing the power spring 203 from releasing energy and pausing the flipping of the protective cover 100. Under the control of the control board 209, the latch 20801 is deviated from the balance wheel 207, and the balance wheel 207 is freed from the obstruction of the latch 20801, allowing the power spring 203 to freely release energy, driving the central wheel axle 202 to rotate clockwise, and simultaneously flipping the protective cover 100 upwards until it covers the seat.

[0087] The power supply module 210 of the control mechanism is equipped with a rechargeable secondary battery. A solar charging panel 21001 is installed on the support plate 103 of the protective cover 100. The solar charging panel 21001 transmits the generated current to the power supply module 210 for charging, achieving self-sufficiency of the power required by the control mechanism. Figure 9 As shown, the solar charging panel 21001, power supply module 210, control board 209, and electronic lock 208 are connected by wires. The displacement information of the rider in a specific area in front of the seat collected by sensor 211 is sent to control board 209 through signal line. Control board 209 and power supply module 210 are set inside box 201. Sensor 211 is fixedly set on the lower surface of base plate 4 and near the front end of seat 1. Sensor 211 is selected as infrared sensor 21101. Control board 209 starts a new round of detection from the first time the rider appears in the detection area. The timer starts from the moment the rider leaves the detection area. If there is no rider for X seconds, the electronic lock 208 is powered on, causing the locking tongue 20801 to deviate from the swing wheel 207 and automatically flip the protective cover 100 until it covers the seat. The value of X is in the range of 1 second ≤ X ≤ 10 seconds.

[0088] Optionally, in one embodiment, the tray 301 can be configured as needed, such as... Figure 10 As shown, the tray 301 is fixed below the base plate 4, so that the tray 301 and the base plate 4 are kept in a relatively fixed position.

[0089] Optionally, in one embodiment, the box 201 has a semi-open structure, such as... Figure 11 , Figure 12 As shown, the box body 201 is fixed to the base plate 4 or tray 301 of the cushion 1; the base plate 4 replaces the upper side wall of the box body 201, or the tray 301 replaces the lower side wall of the box body 201, and the two can be fixed to each other by riveting, gluing or integral injection molding.

[0090] Optionally, in one embodiment, the combination of the escapement mechanism is selected from one of the following groups: as Figure 4 shown, the combination of the escape wheel 206 and the balance wheel 207, Figure 13 shown, the combination of the escape wheel 206, the escape fork 212, the hairspring 213 and the balance wheel 207.

[0091] Optionally, in one embodiment, the power spring 203 is selected from one of the following groups: torsion spring and mainspring. The power spring 203 is arranged on the center wheel shaft 202, one end is arranged on the limit pin 20402 of the main gear 204, and the other end is arranged on the box body 201. As Figure 8 shown, the power spring 203 is selected as an assembly structure of a torsion spring.

[0092] Optionally, in one embodiment, the delay flip device group is further configured with a boost spring 214 and a limit pin 20202. The boost spring 214 is arranged on the left end or the right end of the center wheel shaft 202. The limit pin 20202 is arranged on the center wheel shaft 202 and abuts against one end of the boost spring 214. The other end of the boost spring 214 is arranged on the tray 301 or the box body 201. The boost spring 214 is selected from one of the following groups: torsion spring and mainspring. As Figure 14 shown, the boost spring 214 is selected as an assembly structure of a torsion spring. When the protective cover 100 is flipped backward, the center wheel shaft 202 rotates counterclockwise, driving the main gear 204 to rotate counterclockwise. The limit pin 20402 of the main gear 204 causes the power spring 203 to tighten and store energy. At the same time, the limit pin 20202 of the center wheel shaft 202 causes the boost spring 214 to tighten and store energy synchronously with the power spring 203. When the backward flipping of the protective cover 100 stops, the power spring 203 and the boost spring 214 release energy at the same time, jointly driving the center wheel shaft 202 to rotate clockwise, driving the protective cover 100 to flip upward above the seat cushion 1. During the process of the power spring 203 and the boost spring 214 releasing energy, when the control mechanism prevents the power spring 203 from releasing energy, the power generated when the boost spring 214 releases is not enough to drive the protective cover 100 to flip, and there is not enough power to drive the center wheel shaft 202 to rotate clockwise. The limit pin 20202 of the center wheel shaft 202 causes the boost spring 214 to continue to maintain the tightened state, and the boost spring 214 pauses to release energy. The corresponding stiffness coefficients are adapted for the power spring 203 and the boost spring 214 according to the actual power required to flip the protective cover 100.

[0093] Optionally, in one embodiment, a shaft hole is provided at the lower end of the support plate 103 of the protective cover 100. The shape of the center wheel shaft 202 is selected from one of the following groups: as Figure 1 shown, the "one" shape, as Figure 15 shown, the "C" shape, as Figure 16 shown, the double "U" shape, as Figure 17 shown, the double "L" shape and as Figure 18 The double "Z" shape shown; as Figure 19 As shown, when the shape of the central wheel axle 202 is selected as a double "U" shape, the left and right "U" shaped central wheel axles 202 are inserted into the lower shaft holes of the support plate 103 from the left and right sides of the support plate 103 respectively and are fixedly connected to each other; as Figure 20 As shown, when the shape of the central axle 202 is selected as a double "U" shape, one end of the central axle 202 is inserted into the shaft hole provided at the tail of the cover 101 of the protective cover 100 and fixedly connected to it, so that the central axle 202 also has the function of vertically supporting the protective cover 100 and replacing the support plate 103; when the shape of the central axle 202 is selected as a "C" shape, double "U" shape, or double "L" shape, it can also be equipped with... Figure 5 The shaft hole of the box 201 shown is located behind the front side wall of the box 201.

[0094] Optionally, in one embodiment, the central axle 202 is further configured with a limit pin 20203, a positioning pin 20204, and a positioning spring 215; the positioning spring 215 is selected from one of the following groups: torsion springs and mainsprings, such as... Figure 21 As shown, the positioning spring 215 is selected as a torsion spring; the shape of the central axle 202 is selected as a double "U" shape, the central axle 202 extends into the lower end shaft hole of the support plate 103 and is rotatably connected to the support plate 103, the outer diameter of the central axle 202 is the same as the inner diameter of the lower end shaft hole of the support plate 103; the positioning pin 20204 abuts against the front side of the support plate 103 to prevent the support plate 103 from rotating counterclockwise around the central axle 202, and a vertical groove is provided on the tube body of the lower end shaft hole of the support plate 103 at the positioning pin 20204, so that the support plate 103 is not restricted by the positioning pin 20204 when rotating clockwise around the central axle 202; one end of the positioning spring 215 abuts against the limiting pin 20203, and the other end abuts against the rear side of the support plate 103 to prevent the support plate 103 from rotating clockwise around the central axle 202; as Figure 22 As shown, under the combined action of the positioning pin 20204 and the positioning spring 215, the support plate 103 and the central wheel axle 202 are kept relatively fixedly connected. When the protective cover 100 covers the seat cushion 1, the torque of the positioning spring 215 is sufficient to prevent the support plate 103 from rotating clockwise around the central wheel axle 202, so that the central wheel axle 202 and the support plate 103 work together to achieve the effect of vertically supporting the protective cover 100; when the vertical external force is downward, the protective cover 100 is lowered, driving the protective cover 100 and the support plate 103 to descend to the position shown in the figure. Figure 23During the process shown, the central wheel shaft 202 embedded in the lower end shaft hole of the support plate 103 rotates counterclockwise relative to the lower end shaft hole of the support plate 103, causing the positioning spring 215 to tighten and store energy. At the same time, the central wheel shaft 202 embedded in the lower end shaft hole of the support plate 103 rotates counterclockwise around the shaft hole of the box 201. The central wheel shafts 202 on the shaft holes on the left and right walls of the box 201 rotate counterclockwise synchronously. Through the transmission of the limiting pins 20201 and 20401, the main gear 204 rotates counterclockwise. The limiting pins 20402 follow the main gear 204. 4. A counter-clockwise rotation causes the power spring 203 to tighten and store energy. During the downward action of a vertical external force, the positioning spring 215 and the power spring 203 simultaneously tighten and store energy, eliminating the influence of the external force on the delayed flip cover assembly 200. When the external force is removed, the positioning spring 215 releases energy and drives the front side of the support plate 103 to abut against the positioning pin 20204. The power spring 203 releases energy to drive the central axle 202, embedded in the lower end shaft hole of the support plate 103, to rotate clockwise around the shaft hole of the box 201, causing the protective cover 100 to rise and return to its original position. Optionally, in one embodiment, the structure can be simplified as follows: Figure 22a as well as Figure 22b As shown, where Figure 22a Remove the balance wheel Figure 22b The gears and escapement mechanism are eliminated, retaining only the main gear. These two structural elements simplify the existing structure, making it simpler and more reliable. Figure 22a and Figure 22b The structure can only achieve instantaneous closure of the protective shield.

[0095] Optionally, in one embodiment, the protective cover 100 is provided with ventilation holes. When the cover 101 is in a horizontal state, a plurality of horizontal ventilation holes are provided around the side 102 to ensure horizontal ventilation and prevent rainwater from flowing into the inside of the protective cover 100 when it drips onto the surface of the protective cover 100.

[0096] Alternatively, in one embodiment, the power supply method of the control board 209 is selected from one of the following groups: power supply module 210 and shared bicycle battery 9.

[0097] Optionally, in one embodiment, the method for collecting riding status information by the control board 209 is selected from one of the following groups: the sensor 211 and the lock / unlock command of the shared bicycle. The sensor 211 is selected from one of the following groups: infrared sensor 21101, ultrasonic sensor 21102 and photoelectric sensor 21103. When the information collection method is selected as the lock / unlock command of the shared bicycle, the control board 209 establishes a wireless or wired communication link with the shared bicycle controller 10. When the control board 209 obtains the lock command, it determines that the riding has entered a non-riding state. The control board 209 supplies power to the electronic lock 208, causing the lock tongue 20801 to retract and deviate from the swing wheel 207. The power spring 203 begins to release energy and drives the protective cover 100 to flip upwards towards the seat 1 until it covers the seat 1.

[0098] Optionally, in one embodiment, the battery of the power supply module 210 is selected from one of the following groups: replaceable primary batteries and rechargeable secondary batteries; the energy storage source of the rechargeable battery is selected from one of the following groups or a combination thereof: solar charging panel 21001 and micro generator 21002; such as Figure 24 As shown, when the power source of the rechargeable battery is selected as the micro generator 21002, the central shaft of the escape wheel 206 is fixedly connected to the central shaft of the gearbox of the micro generator 21002. When the escape wheel 206 rotates, its central shaft drives the central shaft of the gearbox to rotate, thereby increasing the rotor speed of the generator 21002 through the gearbox. The current generated by the rotor rotation of the micro generator 21002 is supplied to the battery of the power supply module 210. The charging time is the flipping time of the protective cover 100 automatically covering the seat cushion 1. According to the actual power required by the flipping protective cover 100 and the driving micro generator 21002, the power spring 203 is matched with the corresponding stiffness coefficient. It can be fixedly connected to the central shaft of the gearbox of the micro generator 21002 by the central shaft of the driven gear 205 as needed.

[0099] Optionally, in one embodiment, the delayed flip cover assembly is further configured with a beveled ring 217 and a touch switch 218, such as Figure 25 As shown, the beveled ring 217 is fixedly mounted on the central axle 202, and rotates with the central axle 202. The touch switch 218 is fixedly mounted inside the housing 201, and the button end of the touch switch 218 rests against the beveled ring 217. Figure 26 As shown, the two contacts of the touch switch 218 are connected to the line between the control board 209 and the power supply module 210; when the protective cover 100 covers the seat cushion 1, the positional relationship between the beveled ring 217 and the touch switch 218 is as follows. Figure 25 As shown, the touch switch 218 is in the off state, as... Figure 26 As shown, the circuit between the control board 209 and the power supply module 210 is disconnected; when the protective cover 100 is flipped behind the seat cushion 1, the central wheel axle 202 rotates counterclockwise, synchronously driving the inclined ring 217 to rotate counterclockwise and press the touch switch 218, entering as... Figure 27 As shown, the touch switch 218 is in the open state, as indicated. Figure 28 As shown, the circuit between the control board 209 and the power supply module 210 is connected.

[0100] The workflow of this embodiment is as follows:

[0101] Before cycling, such as Figure 1 , Figure 4 , Figure 7 , Figure 8 As shown, when the protective cover 100 is manually flipped to the rear under the seat cushion 1, the drive center wheel axle 202 rotates counterclockwise during the manual flipping process. The center wheel axle 202 drives the first limit pin 20201 of the center wheel axle to rotate. The first limit pin 20201 of the center wheel axle 202 drives the first limit pin 20401 of the main gear 204 to rotate. The first limit pin 20401 of the main gear 204 drives the main gear 204 to rotate counterclockwise, gradually causing the power spring 203, which is set on the second limit pin 20402 of the main gear 204, to tighten and store energy. Since the driven gear 205 is configured as a one-way transmission gear, the driven gear 205 does not transmit power to the escape wheel 206, and the escape wheel 206 does not rotate with the manual flipping of the protective cover 100.

[0102] When cycling, such as Figure 29 As shown, during the flipping of the protective cover 100 and when the flipping of the protective cover 100 stops, the locking tongue 20801 of the electronic lock 208 touches the balance wheel 207, preventing the balance wheel 207 from swinging, preventing the escape wheel 207 and the driven gear 205 from rotating, and thus preventing the main gear 204 from rotating clockwise, so that the power spring 203 cannot release energy. During the ride, the locking tongue 20801 always touches the balance wheel 207, so that the protective cover 100 is kept at the rear of the seat 1, achieving the normal riding effect.

[0103] At the end of the ride, such as Figure 30 As shown, when the rider leaves the seat 1, the control board 209 promptly obtains the information collected by the sensor 211. The control board 209 analyzes that the rider is no longer in the specific area of ​​the seat 1, and uses this as a reason to transition to a non-riding state. The control board 209 supplies power to the electronic lock 208, causing the locking tongue 20801 to retract and deviate from the balance wheel 207. When there is no external force to stop the balance wheel 207, it begins to swing, canceling the obstruction of the escape wheel 206, the driven gear 205, and the master gear 204. The master gear 204 begins to rotate clockwise during the energy release process of the power spring 203, synchronously driving the center wheel axle 202 to rotate clockwise, driving the protective cover 100 to flip upwards on the seat 1 until it covers the seat 1.

[0104] like Figure 30As shown, when the protective cover 100 is flipped at any angle, it can also be manually flipped upwards towards the seat cushion 1 until it covers the seat cushion 1. When the protective cover 100 is manually flipped upwards towards the seat cushion 1, the central wheel axle 202 is driven to rotate clockwise. The limiting pin 20401 of the central wheel axle 202 is deviated from the limiting pin 20401 of the main gear 204, and the central wheel axle 202 rotates freely clockwise without the resistance of the main gear 204.

[0105] like Figure 31 As shown, during the process of driving the protective cover 100 to flip, when the angle between the cover surface 101 of the protective cover 100 and the upper surface of the seat cushion 1 is β°, the power spring 203 releases all its energy and stops driving. The protective cover 100 falls under its own gravity and covers the seat cushion 1. The value of β is in the range of 20° < β < 90°.

[0106] When the protective cover 100 is flipped to the lowest point behind the seat cushion 1, the timing starts from the first moment when the power spring 203 releases energy, causing the protective cover 100 to automatically flip until it covers the seat cushion 1. The time taken is t seconds, where t ranges from 5 seconds to 120 seconds. The value of t depends on the gear parameters of the main gear 204, the driven gear 205, and the escape wheel 206.

[0107] The maximum rotation angle of the central wheel axle 202 is γ°, and the value of γ is in the range of 90°≤γ≤180°.

[0108] Sensor 211 detects whether the rider is in a specific area, which is a fan-shaped area of ​​K meters and P degrees in front of the front end of the seat 1 as the reference point; the value range of K is 0.2m≤K≤0.6m, and the value range of P is 90°≤P≤120°.

[0109] like Figure 22 As shown, under the vertical support of the support plate 103, the cover 101 maintains a certain gap with the seat cushion 1, and the height of the gap is H mm. The value of H is in the range of 0 mm ≤ H ≤ 30 mm.
