Description

Technical Field

[0001] This utility model relates to the field of toy gun technology, and in particular to a toy gun. Background Technology

[0002] Water bullet toy guns can imitate guns firing bullets, making them very fun and playable.

[0003] Water bullet toy guns in related technologies typically include a shell, a firing control assembly disposed on the shell, a cylinder, a motor, and other main components, among which the firing control assembly is a relatively important part.

[0004] The patent with authorization announcement number CN213335782U, entitled "Internal Gearbox Structure of a Water Bullet Toy Gun," discloses an internal structure with a continuous firing effect. However, it also has many areas for improvement; for example, the internal gearbox structure lacks a single-shot control structure, making it difficult to provide a single-shot effect.

[0005] The patent with authorization announcement number CN 206905614 U and utility model name is a multi-mode firing device for an electric toy gun. Although it provides single-shot and burst-fire modes, its brake triggering structure uses a brake control structure composed of Hall sensor 18 and permanent magnet 19, which requires a high-cost and complex Hall sensor.

[0006] Therefore, there is an urgent need to provide a toy gun that can provide a new braking triggering structure that is simple in structure and low in cost. Utility Model Content

[0057] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0058] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0063] Figure 1 A three-dimensional structural diagram of a toy gun provided for embodiments of this application. Figure 1 ; Figure 2 A three-dimensional structural diagram of a toy gun provided for embodiments of this application. Figure 2 ; Figure 1 and Figure 2 A three-dimensional diagram of the toy shelf is shown from two different side views. (Reference) Figures 1-7 This application provides a toy gun comprising a housing 1, a cylinder assembly 2, a rack 3, a half gear 4, a control assembly 6, a cam 7, and a motor 5. The cylinder assembly 2 includes a cylinder body 21 fixed to the housing 1, a piston rod 22 slidably disposed on the cylinder body 21, and a compression spring 23 disposed on the housing 1 and connected to the piston rod 22. The piston rod 22 is reciprocating along a first direction X between a stretched position and a compressed position. The rack 3 is fixed to the piston rod 22 and extends along the first direction X. The half gear 4 is rotatably disposed on the housing 1 and configured to mesh with the rack 3. The transmission mechanism moves the piston rod 22 to the extended position; the motor 5 is connected to the half gear 4 via a transmission; the control component 6 includes a central control plate 61, a brake switch 62, and a trigger switch 63 disposed in the housing 1. The central control plate 61 is electrically connected to the brake switch 62, the trigger switch 63, and the motor 5. The brake switch 62 has a first trigger button 621; the cam 7 is coaxially and fixedly connected to the half gear 4. When the piston rod 22 is in the extended position, the cam 7 abuts against the first trigger button 621 and triggers the brake switch 62. When the piston rod 22 leaves the extended position, the cam 7 releases the trigger of the brake switch 62.

[0064] Compared to the existing brake switch 62 design with a magnet and a Hall sensor, the toy gun provided in this application adds a cam 7 and a brake switch 62 with a first trigger button 621. Its brake triggering design is a mechanical contact triggering structure. When the piston rod 22 is in the extended position, the cam 7 abuts against the first trigger button 621 and triggers the brake switch 62. The structure is simple and the cost is low.

[0065] Explanatory purposes: the circuit connections between the central control board 61 and the brake switch 62 and trigger switch 63, as well as the subsequent trigger control circuit and control method, can use existing ones. This application does not limit or improve them, so they will not be described in detail here.

[0066] In some implementations, reference Figures 3-7 The brake switch 62 is a micro switch. The first trigger button 621 is located on one side of the radial direction of the half gear 4. The first trigger button 621 has an abutment surface 6211 facing the half gear 4, and the abutment surface 6211 is a rounded curved surface. The rounded curved surface can realize the contact triggering function on the one hand, and help to avoid jamming problems caused by unreasonable structural shape on the other hand. Specifically, when the cam 7 rotates and passes the first trigger button 621, the rounded curved surface of the first trigger button 621 can tilt in the direction of rotation of the cam 7.

[0067] Explained, a microswitch is a switch that uses external mechanical force to trigger the opening and closing of a circuit. When a certain force or displacement is applied, the internal contacts of the microswitch actuate, thereby controlling the opening and closing of the circuit. Microswitches belong to the category of mechanical switches; they are very small, highly sensitive, and can be activated by a very small torque. Hall effect switches belong to the category of electrical inductive switches. Although they are also small and highly sensitive, their working principle is more complex, and they are relatively more expensive than microswitches.

[0068] refer to Figures 3-7 In some embodiments, the toy gun also includes a trigger 8, which is rotatably disposed on the housing 1. The trigger 8 has an abutment end 81 and can reciprocate between a pressed position and a non-pressed position. When the trigger 8 is in the pressed position, the abutment end 81 triggers the trigger switch 63. When the trigger 8 is in the non-pressed position, the abutment end 81 releases the trigger switch 63.

[0069] Explanatoryly, the control circuit or control method of the trigger switch 63 and the central control board 61 can be achieved using existing methods. The improvement of this application does not lie in this, and will not be elaborated upon.

[0070] In some implementations, reference Figures 3-7The trigger switch 63 is a micro switch with a second trigger button 631, which is configured to abut against the trigger 8. Similarly, micro switches are mechanical switches, very small in size, highly sensitive, and require only a small torque to operate; they are also relatively cheaper than Hall effect switches.

[0071] In some implementations, reference Figures 3-7 The central control board 61 includes a microcontroller. The microcontroller controls the start and stop of the motor 5 based on the electrical signals received from the brake switch 62 and the trigger switch 63. The control method can use existing methods, and this application will not improve upon them, nor will it be described in detail.

[0072] refer to Figures 3-7 In some embodiments, the toy gun also includes a gear assembly 100, through which the motor 5 is connected to the half gear 4 via the gear assembly 100. The gear assembly 100 serves as an indirect transmission mechanism, and the number and type of gears in the gear assembly 100 can be determined according to requirements, providing more flexibility for the arrangement of internal components of the toy gun.

[0073] In some implementations, reference Figures 3-7 The gear assembly 100 includes a first bevel gear 110, a second bevel gear 120, a first spur gear 130, a second spur gear 140, a third spur gear 150, and a fourth spur gear 160. The first bevel gear 110 is coaxially fixed to the rotating shaft of the motor 5; the second bevel gear 120 is rotatably mounted on the housing 1 and meshes with the first bevel gear 110; the first spur gear 130 is coaxially fixedly connected to the second bevel gear 120; the second spur gear 140 is rotatably mounted on the housing 1 and meshes with the first spur gear 130; the third spur gear 150 is coaxially fixedly connected to the second spur gear 140; and the fourth spur gear 160 is coaxially fixedly connected to the half gear 4 and meshes with the third spur gear 150.

[0074] In some implementations, reference Figures 3-7 The axis of the first bevel gear 110 is perpendicular to the axis of the second bevel gear 120, which plays a role in rotational reversal and facilitates more flexible adjustment of the arrangement position of the motor 5.

[0075] refer to Figures 3-7 In some embodiments, the diameter of the first spur gear 130 is smaller than the diameter of the second spur gear 140, thereby achieving a single-stage reduction transmission between the first spur gear 130 and the second spur gear 140. The reduction transmission is beneficial for increasing the rotational torque.

[0076] In some implementations, reference Figures 3-7The diameter of the third spur gear 150 is smaller than that of the fourth spur gear 160, thus achieving another stage of speed reduction transmission between the third spur gear 150 and the fourth spur gear 160. Speed ​​reduction transmission is beneficial to increasing rotational torque.

[0077] refer to Figures 3-7 In some embodiments, the toy gun also includes a one-way ratchet 200, a pawl 300, and an elastic element 400. The one-way ratchet 200 is coaxially and fixedly connected to the second bevel gear 120; the pawl 300 is rotatably connected to the housing 1; the elastic element 400 is connected to the pawl 300 and the housing 1, and is configured to provide a spring force to the pawl 300 that allows the pawl 300 to elastically abut against the teeth of the one-way ratchet 200. Through the cooperation of the one-way ratchet 200 and the pawl 300, the reverse rotation of the second bevel gear 120 can be prevented, allowing it to rotate only in one direction. This prevents the cam 7 and the half gear 4 from rotating in reverse, avoiding the toy gun from reversing. The elastic element 400 can be a torsion spring, tension spring, compression spring, etc., that provides a spring force to the pawl 300 that allows the pawl 300 to elastically abut against the teeth of the one-way ratchet 200.

[0078] Furthermore, in some implementations, reference is made to... Figures 3-7 The one-way ratchet 200, the second bevel gear 120, and the first spur gear 130 are integrally molded structures. Integral molding can reduce the number of parts and reduce assembly processes.

[0079] Further, refer to Figures 3-7 In some embodiments, the third spur gear 150 and the second spur gear 140 are integrally formed.

[0080] Further, refer to Figures 3-7 In some embodiments, the cam 7, the fourth spur gear 160, and the half gear 4 are integrally formed, which can reduce the number of parts and reduce assembly processes.

[0081] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above embodiments illustrate only one implementation of the present utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the appended claims.
