locomotive side windows

Abstract

This application relates to the field of railway locomotive side windows, and more particularly to a locomotive side window that, through the interaction of a connecting rod mechanism, a balancing mechanism, an electric drive device, and a mode switching mechanism, has two modes of opening and closing: purely mechanical manual opening and closing; and electrically powered lifting and closing. The mode switching mechanism controls the up and down movement of the motor base relative to the fixed frame, thereby causing the driving gear in the electric drive device to engage or disengage with the sector gear fixed to the rocker arm. When the driving gear and the sector gear are engaged, the electric drive device can drive the connecting rod mechanism to control the up and down movement of the movable frame, thereby electrically lifting and closing the window. When the driving gear and the sector gear are disengaged, the locomotive driver can manually lift or lower the movable frame to control its up and down movement, thereby achieving purely mechanical manual opening and closing. The two window opening and closing modes can be freely switched to meet the needs of different scenarios.

Description

Technical Field

[0001] The present application relates to the technical field of railway locomotive side windows, and in particular to a locomotive side window. Background Art

[0002] Traditional locomotive windows mostly use purely mechanical manual opening and closing mechanisms, which are relatively laborious to operate. With the rapid development of technology, locomotive drivers are increasingly demanding driving comfort and convenience. Consequently, some push-button electric window systems have emerged on the market. These utilize electric drive components such as motors and electric telescopic rods, along with an electronic control unit, to drive the movable window up and down, offering simple and convenient operation.

[0003] The purely mechanical manual window opening and closing structure and the electric lifting window opening and closing structure each have their advantages and disadvantages. Although the purely mechanical manual window opening and closing structure is relatively laborious to operate, it has good stability and rarely fails because there are no electric drive components such as motors and electric telescopic rods and corresponding electronic control parts. Although the electric lifting window opening and closing structure is simple and convenient to operate, when problems occur in any of the electric drive components such as motors and electric telescopic rods and the corresponding electronic control parts, the lifting function will not be able to be used normally, affecting the opening and closing of the car windows.

The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0049] It should also be noted that, in the embodiments of the present application, the same figure mark represents the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0050] The embodiment of the present application provides a locomotive side window, such as Figure 1-Figure 2 As shown, the motorcycle side window includes a fixed frame 10 , a movable frame 20 , a mounting frame 30 , a connecting rod mechanism 40 , a balancing mechanism 50 , an electric drive device 60 and a mode switching mechanism 70 .

[0051] A window 101 is formed at the top of the fixed frame 10. A movable frame 20 slides up and down within the fixed frame 10. Glass is mounted within the movable frame 20, which drives the glass to rise or fall vertically along the fixed frame 10, thereby opening and closing the window 101. A mounting bracket 30 is mounted on the fixed frame 10 below the window 101.

[0052] The connecting rod mechanism 40 includes a load-bearing rod 41, a rocker arm 42 and a connecting rod 43. The load-bearing rod 41 includes a first rod body 411 and a second rod body 412 connected to one end of the first rod body 411. The connection between the first rod body 411 and the second rod body 412 is hinged to the mounting frame 30, and the end of the first rod body 411 away from the second rod body 412 is pressed against the lower end of the movable frame 20; one end of the rocker arm 42 is hinged to the mounting frame 30; one end of the connecting rod 43 is hinged to the second rod body 412, and the other end is hinged to the rocker arm 42.

[0053] The balancing mechanism 50 is arranged between the fixed frame 10 and the rocker arm 42. The balancing mechanism 50 is used to provide the connecting rod mechanism 40 with a bearing capacity to support the movable frame 20. That is, the force provided by the balancing mechanism 50 to the connecting rod mechanism 40, the gravity of the movable frame 20, and the gravity and friction between the various components can maintain a balance, so that the movable frame 20 can hover at any position.

[0054] The electric drive device 60 is arranged on the fixed frame 10 below the mounting frame 30. The electric drive device 60 includes a motor base 61, a drive motor 62, a driving gear 63 and a fan gear 64. The drive motor 62 is movably mounted on the fixed frame 10 through the motor base 61. The driving gear 63 is fixed on the motor shaft of the drive motor 62. The fan gear 64 is fixed to the end of the rocker arm 42 away from the mounting frame 30.

[0055] The mode switching mechanism 70 is provided on the fixed frame 10 and connected to the motor base 61. Under the action of the mode switching mechanism 70, the motor base 61 can move up and down relative to the fixed frame 10 to engage or disengage the driving gear 63 with the sector gear 64. When the driving gear 63 and the sector gear 64 are in an engaged state, the electric drive device 60 can drive the connecting rod mechanism 40 to operate to control the up and down movement of the movable frame 20. When the driving gear 63 and the sector gear 64 are in a disengaged state, the movable frame 20 is manually lifted or pressed down to control the up and down movement of the movable frame 20.

[0056] It is understood that when the driving gear 63 and the sector gear 64 are in meshing state, the drive motor 62 in the electric drive device 60 drives the driving gear 63 to rotate, and the rotation of the driving gear 63 drives the sector gear 64 meshed therewith to rotate. Since the sector gear 64 is fixed to the end of the swing arm 42 away from the mounting frame 30, the rotation of the sector gear 64 drives the swing arm 42 to swing about its hinged connection with the mounting frame 30, and then drives the support rod 41 to swing about its hinged connection with the mounting frame 30 through the connecting rod 43. By controlling the forward and reverse rotation of the drive motor 62, the movable frame 20 can be controlled to move up and down along the fixed frame 10. When the driving gear 63 and the sector gear 64 are out of meshing state, the swing of the swing arm 42 is not restricted by the sector gear 64 located thereon and the driving gear 63 fixed to the motor shaft of the drive motor 62. Therefore, by manually lifting or pressing the movable frame 20, the movable frame 20 can be controlled to move up and down along the fixed frame 10.

[0057] In the embodiment of the present application, the locomotive side window cooperates with the connecting rod mechanism 40, the balancing mechanism 50, the electric drive device 60 and the mode switching mechanism 70, and has two modes of purely mechanical manual window opening and closing and electric lifting and closing window opening and closing. The mode switching mechanism 70 can realize free switching between the two window opening and closing modes to meet the usage requirements in different scenarios.

[0058] In addition, compared with the existing locomotive side windows that use a single electric drive lifting method, when the electric drive lifting structure fails or malfunctions, the mode switching mechanism 70 can be used to switch to manual control of window lifting, without affecting the normal opening and closing of the window.

[0059] The driving motor 62 may be a double-ball shaft brushless DC motor, which has the characteristics of high torque, high power, high efficiency, long life (up to 10,000 operating hours), low noise, and automatic overload protection.

[0060] In one embodiment, if Figure 1-Figure 2 As shown, the length of the first rod 411 is greater than the length of the second rod 412, and the support rod 41 formed by the connection between the first rod 411 and the second rod 412 is L-shaped. A roller 4111 is rotatably provided at the end of the first rod 411 that abuts the movable frame 20. The roller 4111 is used to reduce wear between the first rod 411 and the movable frame 20, thereby extending the service life.

[0061] In one embodiment, if Figure 1-Figure 2 As shown, one end of the connecting rod 43 is hinged to an end of the second rod body 412 away from the first rod body 411 , and the other end of the connecting rod 43 is hinged to the middle part of the rocker arm 42 .

[0062] In one embodiment, if Figure 3-Figure 4As shown, a mounting plate 80 is provided on the fixed frame 10 below the mounting frame 30, one end of the motor seat 61 is hinged to the mounting plate 80, and the other end is connected to the mounting plate 80 through an elastic member 611; the driving motor 62 is fixed on the motor seat 61, and the motor shaft of the driving motor 62 is close to the elastic member 611, and the switching mechanism is connected to one end of the motor seat 61 close to the elastic member 611.

[0063] The mounting plate 80 provides a mounting carrier for the electric drive device 60 on the fixed frame 10. By hingedly connecting one end of the motor base 61 to the mounting plate 80 and connecting the other end to the mounting plate 80 via an elastic member 611, the motor shaft of the drive motor 62 is arranged close to the elastic member 611. This arrangement not only achieves reliable installation of the motor base 61 on the mounting plate 80, but also enables the motor base 61 to rotate around the hinge under the drive of the switching mechanism, driving the drive motor 62 to move up and down, thereby achieving engagement or disengagement of the driving gear 63 and the sector gear 64.

[0064] Specifically, the elastic member 611 can be a vertically arranged spring, the upper and lower ends of the spring are respectively connected to the motor base 61 and the mounting plate 80, and the spring provides an upward elastic force for the motor base 61.

[0065] In a specific embodiment, Figure 3-Figure 4 As shown, the driving gear 63 and the sector gear 64 are located on the same side of the mounting plate 80, and the motor base 61 and the drive motor 62 are located on the other side of the mounting plate 80. A vertically extending avoidance hole is provided on the mounting plate 80, and the motor shaft of the drive motor 62 passes through the avoidance hole and is fixedly connected to the driving gear 63.

[0066] Due to the above arrangement, the driving part composed of the motor base 61 and the driving motor 62 and the transmission part composed of the driving gear 63 and the sector gear 64 do not interfere with each other, and the layout is reasonable.

[0067] In one embodiment, if Figure 3-Figure 6 As shown, the mode switching mechanism 70 includes a base shell 71, a turntable 72, an eccentric wheel 73, a linkage rod 74 and a rotating handle 75. The base shell 71 is installed on the fixed frame 10, the turntable 72 is rotatably arranged in the base shell 71, the eccentric wheel 73 is arranged on the side of the turntable 72 close to the fixed frame 10, and one end of the linkage rod 74 is provided with a ring 741 adapted to the eccentric wheel 73. The ring 741 is sleeved on the eccentric wheel 73, and the other end of the linkage rod 74 is connected to the motor base 61; the rotating handle 75 is provided on the side of the turntable 72 away from the fixed frame 10. Rotating the rotating handle 75 drives the linkage rod 74 to move up and down through the eccentric wheel 73, and then drives the motor base 61 to move up and down, so that the driving gear 63 and the sector gear 64 on the drive motor 62 are switched between the engaged state and the disengaged state.

[0068] The mode switching mechanism 70 realizes mode switching through a purely mechanical structure. Compared with an electric switching mechanism, it has reliable performance and a low failure rate.

[0069] Among them, such as Figure 3 As shown, the rotary handle 75 is also provided with "electric" and "manual" text markings and arrows. These text markings and arrows are arranged as follows: when the rotary handle 75 is rotated so that the "electric" marking is facing upward, the driving gear 63 and the sector gear 64 are in meshing state, enabling electric lifting and opening of the window; when the rotary handle 75 is rotated so that the "manual" marking is facing upward, the driving gear 63 and the sector gear 64 are disengaged, enabling manual lifting and opening of the window. The locomotive driver can check the markings on the rotary handle 75 to understand the current mode of the locomotive side window, providing convenient operation.

[0070] Preferably, a bearing is provided between the turntable 72 and the seat shell 71 , and the bearing is used to reduce the friction between the turntable 72 and the seat shell 71 , so that the turntable 72 can rotate more flexibly.

[0071] Specifically, if Figure 7 As shown, the turntable 72 and the eccentric wheel 73 are an integrated structure, and are easily manufactured by plastic integral injection molding. Of course, they can also be manufactured by milling.

[0072] In a specific embodiment, Figure 6-Figure 9 When the handle 75 is in the unlocked position, the locking cam 77 is engaged with the locking cam 78 and the retaining ring 71 is engaged with the locking cam 76. When the handle 75 is unlocked, the locking cam 77 is engaged with the locking cam 76 and the retaining ring 71 is engaged with the locking cam 76.

[0073] By the above arrangement, only when the rotating handle 75 is pressed and rotated, the rotating disk 72 and the eccentric wheel 73 can be driven to rotate by the rotating handle 75, and then the mode switching can be achieved through the linkage rod 74, which can prevent accidental contact.

[0074] In a specific embodiment, Figure 6As shown, one of the opposing inner sides of the base housing 71 and the rotating handle 75 is provided with a plurality of positioning grooves 711, and the other is provided with a plurality of elastic positioning members 751. When the driving gear 63 and the sector gear 64 are in the meshing state or in the disengaging state, the plurality of elastic positioning members 751 are respectively embedded in the plurality of positioning grooves 711. This design, through the mutual cooperation between the elastic positioning members 751 and the positioning grooves 711, can play a certain role in positioning the rotating handle 75, and has the function of preventing accidental contact.

[0075] Specifically, the elastic positioning member 751 can be a ball plunger.

[0076] In one embodiment, if Figure 1-Figure 2 As shown, the balancing mechanism 50 includes two mounting seats 51 and a plurality of gas springs 52 arranged in parallel between the two mounting seats 51 . The opposite ends of each gas spring 52 are hinged to the two mounting seats 51 , respectively. One of the mounting seats 51 is fixed on the fixed frame 10 , and the other mounting seat 51 is hinged to the rocker arm 42 .

[0077] Specifically, the balancing mechanism 50 and the connecting rod 43 are respectively located on the left and right sides of the rocker arm 42 , and the gas spring 52 in the balancing mechanism 50 is arranged substantially parallel to the horizontal plane.

[0078] The gas spring 52 has significant advantages over ordinary springs: relatively slow speed, little change in dynamic force (generally within 1:1.2), and easy control.

[0079] It should be noted that the number and specifications of the gas springs 52 can be selected according to actual conditions and are not limited here.

[0080] In one embodiment, the motorcycle side window further includes a controller (not shown in the figure) and an electric control button (not shown in the figure) and a voice control module (not shown in the figure) electrically connected to the controller. The controller is electrically connected to the drive motor 62. The electric control button and the voice control module are used to control the operation of the drive motor 62 manually and by voice, respectively.

[0081] The electric control button offers both a light-touch, inching control and a long-press, continuous control, similar to the power windows in a car. The voice control module offers voice control functions such as wake-up, retreat, window opening, window closing, and opening and closing a certain amount.

[0082] In addition, the locomotive side windows can also be equipped with rain sensors, light curtain sensors, etc. The light curtain sensors can be used to realize non-contact anti-pinch function, and the rain sensors can be used to realize automatic closing of windows in rainy days.

[0083] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are 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.

[0084] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
