[0042] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0043] The direction terms mentioned in the utility model, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only the orientation of the drawings, and the direction terms are used to explain and understand the utility model, rather than to limit the utility model.

[0044] The terms "first", "second", etc. in the utility model are only for the purpose of description, and cannot be understood as indicating or implying relative importance, and are not limited as the order.

[0045] In the utility model, unless otherwise clearly defined and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] When passengers take the bus, sometimes they put paper money, sometimes they put coins, and sometimes they roll the paper money into a ball. The balled paper money can jam the coin slot of the coin machine, preventing the following passengers from normal coin feeding. Therefore, the coin machine is internally provided with a coin rolling mechanism, which usually includes a set of driving wheels, a set of floating wheels and a compression spring. The driving wheels rotate at a fixed position so that the thicker coins can pass between the driving wheels and the floating wheels. The elastic force of the compression spring moves the floating wheels towards the driving wheels, so that the thicker coins can be clamped between the driving wheels and the floating wheels. Under the action of friction, the driving wheels rotate to convey the coins downward.

[0047] The applicant found that many poor performance coin rolling mechanisms are due to damaged compression springs, mainly because the compression spring is easily corroded or affected by foreign matter, causing the compression spring to not work normally. In the prior art, the compression spring is sleeved on a fixed rod in a bare state, so it is necessary to improve the working environment of the compression spring to improve the performance of the entire mechanism and prolong the service life of the mechanism.

[0048] The following is a preferred embodiment of a bus coin machine provided by the utility model to solve the above technical problems.

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the bus coin machine includes a coin rolling mechanism compatible with different thickness coins. The coin rolling mechanism compatible with different thickness coins includes a base cover 11, a bracket 12, a driving assembly 13, a floating assembly 14, an elastic pushing assembly 15 and a driving assembly 16.

[0050] The base cover 11 is provided with a throwing opening 111. The support 12 is connected to one side of the base cover 11, and the support 12 is provided with a receiving hole 122. The driving assembly 13 is arranged on the support 12, and the driving assembly 13 comprises a first winding wheel 132. The floating assembly 14 is arranged on the support 12, and the floating assembly 14 comprises a second winding wheel 142. The second winding wheel 142 is distributed opposite to the first winding wheel 132, and both of them are located below the throwing opening 111, so as to wind the coins entering the throwing opening 111 into the space between the second winding wheel 142 and the first winding wheel 132. The second winding wheel 142 can move relative to the first winding wheel 132 to approach and move away from the first winding wheel 132. The axial direction of the receiving hole 122 is the same as the moving direction of the second winding wheel 142. Figure 6 The middle arrow direction is the axial direction of the receiving hole 122. It should be noted that the two directions are the same, and are not limited to absolute same direction, and can allow error. The elastic pushing assembly 15 comprises a compression spring 152, which is located in the receiving hole 122 and indirectly abuts against the second winding wheel 142 in the compression direction of the compression spring 152. The driving assembly 16 is used to drive the first winding wheel 132 to rotate. In the process of moving the second winding wheel 142 away from the first winding wheel 132, the second winding wheel 142 compresses the compression spring 152, and the compression spring 152 generates an elastic force to drive the second winding wheel 142 to approach the first winding wheel 132.

[0051] After the coins are thrown into the slot machine, the driving assembly 16 drives the first winding wheel 132 to rotate. The second winding wheel 142 is distributed opposite to the first winding wheel 132, and under the action of friction, the coins can be wound into the space between the second winding wheel 142 and the first winding wheel 132. When the coins are thick, the coins wound into the space between the second winding wheel 142 and the first winding wheel 132 apply a pushing force to the second winding wheel 142 to move the second winding wheel 142 away from the first winding wheel 132, so that the coins can pass through the space between the second winding wheel 142 and the first winding wheel 132 smoothly. Since the second winding wheel 142 indirectly abuts against the compression spring 152, the compression spring 152 is located in the receiving hole 122, and the axial direction of the receiving hole 122 is the same as the moving direction of the second winding wheel 142. When the second winding wheel 142 moves away from the first winding wheel 132, the compression spring 152 is compressed, and the compressed compression spring 152 generates an elastic force to drive the second winding wheel 142 to approach the first winding wheel 132, so that the second winding wheel 142 approaches the first winding wheel 132. Since the coins are located between the second winding wheel 142 and the first winding wheel 132, the approach of the second winding wheel 142 to the first winding wheel 132 increases the friction between the second winding wheel 142 and the coins, and also increases the friction between the first winding wheel 132 and the coins, so that the coins pass through the space between the second winding wheel 142 and the first winding wheel 132 smoothly.

[0052] Since the compression spring 152 is located in the accommodating hole 122, the hole wall of the accommodating hole 122 protects the compression spring 152, which can avoid the compression spring 152 from contacting with foreign matters, so that the compression spring 152 is not easy to be corroded and is not affected by foreign matters, effectively ensuring that the compression spring 152 can work normally, improving the performance of the entire mechanism, and prolonging the service life of the mechanism. The axial direction of the accommodating hole 122 is the same as the moving direction of the second winding wheel 142, which facilitates the compression spring 152 in the accommodating hole 122 to be compressed by the second winding wheel 142 during movement, on the one hand, the compression spring 152 can be protected by the hole wall of the accommodating hole 122 during compression and rebound, on the other hand, the structure of the coin winding mechanism is simple, which is convenient for production and manufacturing.

[0053] The first winding wheel 132 and the second winding wheel 142 can be rubber wheels or other wheel-shaped structures with certain friction. The number of the first winding wheel 132 and the second winding wheel 142 can be two, three, four or five. In other embodiments, the number of the first winding wheel 132 can be adjusted to at least one, and the number of the second winding wheel 142 can also be adjusted to at least one.

[0054] Please refer to Figure 6 , the elastic pushing assembly 15 further comprises a pushing rod 151, one end of the pushing rod 151 indirectly abuts against the second winding wheel 142, and the other end of the pushing rod 151 abuts against one end of the compression spring 152. The presence of the pushing rod 151 can better push the second winding wheel 142 to approach the first winding wheel 132, and can also prolong the service life of the compression spring 152. Of course, in other embodiments, the pushing rod 151 can be omitted.

[0055] Please refer to Figure 6 , the other end of the pushing rod 151 is located in the accommodating hole 122, and during the movement of the second winding wheel 142 pushed by the pushing rod 151, the compression spring 152 can be completely located in the accommodating hole 122 during compression and rebound, which improves the protection degree of the compression spring 152.

[0056] Please refer to Figure 3 and Figure 5 , the bracket 12 is further provided with an elongated movable hole 121, the length direction of the movable hole 121 is the same as the axial direction of the accommodating hole 122, and one end of the accommodating hole 122 communicates with the movable hole 121. The floating assembly 14 further comprises a floating shaft 141, and the second winding wheel 142 is arranged on the floating shaft 141, and the rotation of the floating shaft 141 can drive the rotation of the second winding wheel 142. At least two second winding wheels 142 can be arranged on the floating shaft 141 to increase the contact between the coins and the second winding wheel 142.

[0057] Further, the floating assembly 14 further comprises a rotating bearing 143 connected to the end of the floating shaft 141. The presence of the rotating bearing 143 can make the rotation of the floating shaft 141 more smooth. The rotating bearing 143 is arranged in the movable hole 121 and can move along the length direction of the movable hole 121 so as to move the second winding wheel 142 away from or close to the first winding wheel 132. One end of the pushing rod 151 abuts against the rotating bearing 143, thereby indirectly abutting the compression spring 152 and the second winding wheel 142. The movable hole 121 can limit the moving track of the rotating bearing 143, so that the second winding wheel 142 can move along the axial direction of the accommodating hole 122 smoothly and is not easy to deviate, thereby enabling the second winding wheel 142 to cooperate with the first winding wheel 132 to clamp the coin. In another embodiment, the rotating bearing 143 can be omitted, and the pushing rod 151 directly abuts against the floating shaft 141.

[0058] Please refer to Figure 1 , Figure 5 and Figure 6 , the bracket 12, the rotating bearing 143 and the elastic pushing assembly 15 can be arranged as two matched ones, so that the relatively thick coin can be smoothly conveyed whether it is thrown close to the left side or the right side. Of course, in other embodiments, the number of the bracket 12, the rotating bearing 143 and the elastic pushing assembly 15 can be flexibly arranged according to actual conditions, which is not limited herein.

[0059] Please refer to Figure 6 , the other end of the accommodating hole 122 penetrates through one side of the bracket 12, so as to facilitate the installation of the compression spring 152. A limiting piece (not shown in the figure) is arranged at the other end of the accommodating hole 122, and one end of the compression spring 152 away from the pushing rod 151 abuts against the limiting piece. During installation, the pushing rod 151 can be first put into the accommodating hole 122 from the other end of the accommodating hole 122, then the compression spring 152 can be installed from the other end of the accommodating hole 122, and finally the limiting piece can be installed. The limiting piece can limit one end of the compression spring 152 away from the pushing rod 151, and one end of the compression spring 152 away from the pushing rod 151 abuts against the limiting piece, so that the other end of the accommodating hole 122 can facilitate the installation of the pushing rod 151 and the compression spring 152.

[0060] Please continue to refer to Figure 6 , the bracket 12 further comprises a threaded hole 123, which is arranged in the axial direction intersecting with the axial direction of the accommodating hole 122 and communicates with the other end of the accommodating hole 122. The limiting piece is threadedly connected to the threaded hole 123 and extends into the accommodating hole 122. The compression spring 152 intersects with the limiting piece, so that the contact area between the compression spring 152 and the limiting piece is larger, thereby making the one end of the compression spring 152 away from the pushing rod 151 more stable.

[0061] Please continue to refer toFigure 6 The axial direction of the threaded hole 123 is perpendicular to the axial direction of the accommodating hole 122, further increasing the contact area between the compression spring 152 and the limiting member, and facilitating the installation of the limiting member into the threaded hole 123.

[0062] Please continue to refer to Figure 6 The threaded hole 123 penetrates through two opposite side walls of the accommodating hole 122, and the threaded hole 123 and the accommodating hole 122 intersect to form a cross shape, which can ensure that the limiting member can extend into the accommodating hole 122, and make the limiting member and the bracket 12 firmly connected.

[0063] Please refer to Figure 6 Both ends of the push rod 151 are provided with chamfered structures, so that it is simple to insert the push rod 151 into the accommodating hole 122 through either end. The other end of the push rod 151 is located in the compression spring 152, which can make the axial direction of the push rod 151 consistent with the axial direction of the compression spring 152, so that the push rod 151 can smoothly move along the axial direction of the accommodating hole 122, and is not easy to deviate.

[0064] Please refer to Figure 6 The movable hole 121 is a racetrack shape, and the radius of the two ends of the movable hole 121 is slightly greater than or equal to the radius of the rotating bearing 143. When the rotating bearing 143 is located at the end of the movable hole 121 away from the accommodating hole 122, the first winding wheel 132 abuts against the second winding wheel 142. Specifically, in this embodiment, the first winding wheel 132 is engaged with the second winding wheel 142. The maximum distance between the first winding wheel 132 and the second winding wheel 142 is generally 9mm. By using the above structure, the size of the movable hole 121 can be accurately determined.

[0065] Please refer to Figure 3 and Figure 4 The driving assembly 13 further comprises a driving shaft 131 and a first driving gear 133. The driving shaft 131 is rotatably connected to the bracket 12, and the first driving gear 133 is connected to the driving shaft 131. The first winding wheel 132 is fixedly sleeved on the driving shaft 131, and the driving assembly 16 is connected to the first driving gear 133. The driving assembly 16 drives the first winding wheel 132 to rotate by driving the first driving gear 133.

[0066] The driving assembly 16 drives the first driving gear 133, the driving shaft 131, the first winding wheel 132, the second driving gear 134, the floating gear 144, the floating shaft 141 and the second winding wheel 142 to rotate, so that the first winding wheel 132 and the second winding wheel 142 are both driven, the coin winding force is increased, and the coin is not easy to be stuck.

[0067] Please refer to Figure 1 and Figure 3 The driving assembly 16 comprises a motor 161 and a driving gear 162, the driving gear 162 is rotationally connected to the support 12 and is in meshing connection with the first driving gear 133, and the diameter of the driving gear 162 is greater than that of the first driving gear 133. In the above structure, when the motor 161 drives the driving gear 162 to rotate one circle, the first driving gear 133 can be simultaneously driven to rotate more than one circle, so that the rotation of the first winding wheel 132 is accelerated, and the coins are rapidly conveyed.

[0068] The working principle of the coin winding mechanism compatible with coins of different thicknesses in the preferred embodiment of the utility model is as follows:

[0069] When installing, the pushing rod 151 can be first put into the containing hole 122 from the other end of the containing hole 122, then the compression spring 152 is installed from the other end of the containing hole 122, and finally the limiting piece is installed.

[0070] After the coins are put into the slot machine, the driving assembly 16 drives the first driving gear 133, the driving shaft 131, the first winding wheel 132, the second driving gear 134, the floating gear 144, the floating shaft 141 and the second winding wheel 142 to rotate, and under the action of friction, the coins can be wound between the second winding wheel 142 and the first winding wheel 132. When the coins are thicker, the coins wound between the second winding wheel 142 and the first winding wheel 132 apply a pushing force to the second winding wheel 142, so as to push the second winding wheel 142 away from the first winding wheel 132, so that the coins can smoothly pass between the second winding wheel 142 and the first winding wheel 132.

[0071] When the second winding wheel 142 moves in the direction away from the first winding wheel 132, the floating shaft 141, the rotating bearing 143 and the push rod 151 also move in the same direction, and the compression spring 152 is compressed, the compressed compression spring 152 generates the elastic force to drive the second winding wheel 142 to be close to the first winding wheel 132, so that the second winding wheel 142 is close to the first winding wheel 132. Since the coin is located between the second winding wheel 142 and the first winding wheel 132, the second winding wheel 142 close to the first winding wheel 132 can increase the friction between the second winding wheel 142 and the coin, and also increase the friction between the first winding wheel 132 and the coin, so that the coin can pass smoothly between the second winding wheel 142 and the first winding wheel 132.

[0072] Thus, the working principle of the coin winding mechanism compatible with different thickness coins of the preferred embodiment is completed.

[0073] The coin winding mechanism compatible with different thickness coins of the utility model, since the compression spring is located in the containing hole, the hole wall of the containing hole protects the compression spring, can avoid the compression spring from contacting with foreign matters to some extent, makes the compression spring not easy to be corroded, also will not be affected by foreign matters, effectively guarantees that the compression spring can work normally, improves the performance of the whole mechanism. The axial direction of the containing hole is same with the moving direction of the second winding wheel, is convenient for the compression spring in the containing hole to be compressed in the moving process of the second winding wheel, on the one hand, makes the compression spring can be protected by the hole wall of the containing hole in the compression and rebound process, on the other hand, makes the structure of the coin winding mechanism simple, is convenient for production and manufacture.

[0074] In conclusion, although the utility model has disclosed above with preferred embodiment, the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme of the utility model within the technical range disclosed by the utility model, all should be covered in the protection scope of the utility model.
