Description

Technical Field

[0001] This utility model relates to a stabilization system for mobile devices, and more particularly to a chassis system with a stabilization mechanism. Background Technology

[0002] In the application of mobile devices, when the device is pushed to a designated position, it needs to be locked to secure it and prevent unexpected movement or shaking during use. There are several commonly used locking methods for mobile devices, such as using one or two foot pedals and a linkage drive mechanism, or using a hydraulic pump, hydraulic lines, and hydraulic cylinders, or utilizing three or four electric support systems.

[0003] However, all of these solutions currently have some drawbacks. For example, the foot-operated and drive mechanism solution is very expensive, while the hydraulic system solution has high initial and maintenance costs and complex maintenance procedures, and the solution with multiple electric support systems is expensive and difficult to achieve simultaneous ground contact and effective support. In addition, all three solutions share a common drawback: large mechanical clearances, resulting in weak stability during support.

[0004] Therefore, an improved chassis system is still needed to address the aforementioned issues. Utility Model Content

[0006] According to one aspect of the present invention, a chassis system for moving and fixing a mobile device is provided. The chassis system includes a chassis assembly and a support assembly. The chassis assembly is used to support and move the device that needs to be moved and fixed. The support assembly is used to lock the device in a designated position when the device is moved to that position. The chassis assembly includes a chassis and casters connected to the chassis. The support assembly includes a support base plate, an electric push rod, and a sliding guide device. The electric push rod and the sliding guide device are arranged between the chassis and the support base plate. The extension and retraction of the electric push rod allows the support base plate to move relative to the chassis under the guidance of the sliding guide device.

[0007] Optionally, the sliding guide device and the electric push rod are arranged side by side between the chassis and the supporting base plate, and the sliding guide device and the electric push rod are arranged such that the sliding guiding direction of the sliding guide device and the extension and retraction direction of the electric push rod are both perpendicular to the main surface of the chassis and / or the main surface of the supporting base plate.

[0008] Optionally, one end of the electric actuator has a protruding connecting portion, the connecting portion and the supporting base plate are fixedly connected by a first fastener, and the other end of the electric actuator opposite to the connecting portion is fixedly connected to the chassis by a second fastener.

[0009] Optionally, the sliding guide device includes a guide rail and a slider configured to slide along the guide rail, wherein the slider is fixedly connected to the supporting base plate via a slider-to-base plate connecting flange, and the guide rail is fixedly connected to the chassis via a guide rail mounting flange.

[0010] Optionally, the slider-to-base plate connecting flange and the guide rail mounting flange are each L-shaped, the L-shape including a transverse bottom and a longitudinal sidewall.

In the following description, numerous specific features are set forth to enable those skilled in the art to gain a more complete understanding of the present invention. However, it will be understood by those skilled in the art that implementations of the present invention may not have some of these specific features.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0020] Figures 1 to 3 A chassis system 100 for moving and fixing a movable device (not shown) according to one embodiment of the present invention is illustrated. Figure 1 and Figure 3 As shown, the chassis system 100 may include a chassis assembly 10 and a support device 20. The chassis assembly 10 can be used to support and move equipment that needs to be moved and fixed, and the support device 20 can be used to lock the equipment in a designated position when the equipment is moved to that position.

[0021] like Figure 2 and Figure 3 As shown, the chassis assembly 10 may include a chassis 1 and casters 2 connected to the chassis 1, and the support assembly 20 may include a support base plate 6, an electric push rod 3, and a sliding guide device. The electric push rod 3 and the sliding guide device may be arranged between the chassis 1 and the support base plate 6.

[0022] When the equipment is moved, the support device 20 is suspended off the ground below the chassis 1, and the chassis system 100 uses casters 2 to move the equipment to the designated position. After reaching the designated position, the support base plate 6 moves downward with the help of electric push rods 3 and sliding guide devices until it touches the ground, thereby fixing the equipment in place at the designated position.

[0023] The sliding guide device and the electric push rod 3 can be arranged side by side between the chassis 1 and the supporting base plate 6. The sliding guide device and the electric push rod 3 can be arranged such that the sliding direction of the sliding guide device and the extension direction of the electric push rod 3 are both perpendicular to the main surface of the chassis 1 and / or the main surface of the supporting base plate 6.

[0024] like Figure 3 As shown, one end of the electric actuator 3 may have a protruding connecting portion 32, and the connecting portion 32 and the support base plate 6 may be fixedly connected by a first fastener 801. Furthermore, by means of a second fastener 802, the other end of the electric actuator 3 opposite to the connecting portion 32 may be fixedly connected to the chassis 1.

[0025] Reference Figure 2 and Figure 3 The sliding guide device may include a guide rail 4 and a slider 5 configured to slide along the guide rail 4. The slider 5 is fixedly connected to the supporting base plate 6 via a slider-to-base plate connecting flange 501, and the guide rail 4 is fixedly connected to the chassis 1 via a guide rail mounting flange 401.

[0026] like Figure 3 Preferably, the slider-to-base plate connecting flange 501 and the guide rail mounting flange 401 are each L-shaped, the L-shape including a transverse bottom and a longitudinal sidewall. The transverse bottom of the slider-to-base plate connecting flange 501 can be fixedly connected to the supporting base plate 6 using a third fastener 803, while its longitudinal sidewall can be fixedly connected to the slider 5 using a third fastener 803. The transverse bottom of the guide rail mounting flange 401 can be fixedly connected to the chassis 1 using a fourth fastener 804, and its longitudinal sidewall can be fixedly connected to the guide rail 4 using a fifth fastener 805.

[0027] The first fastener 801 to the fifth fastener 805 can be a screw or a screw-nut combination.

[0028] In use, when the electric push rod 3 is driven to extend, the electric push rod 3 causes the support base plate 6 to move downward and away from the chassis 1, resulting in an increase in the distance between the support base plate 6 and the chassis 1. Since the guide rail mounting flange 401 is fixedly connected to the chassis 1 and the guide rail 4 is fixedly connected to the guide rail mounting flange 401, the guide rail 4 remains stationary relative to the chassis 1. Meanwhile, the slider fixedly connected to the support base plate 6 and the base plate connecting flange 501 drive the slider 5 to move along the guide rail 4 (downward).

[0029] When moving the device to the designated location and intending to secure it there, the chassis system 100 of this embodiment needs to be operated. First, the electric actuator 3 is energized, causing it to extend. Since the support base plate 6 and the electric actuator 3 are fixedly connected together by the first fastener 801, the support base plate 6 will begin to move downwards under the force of the electric actuator 3. The support base plate 6 and the slider 5 are rigidly connected by the slider-to-base plate connecting flange 501 and the third fastener 803. Therefore, the support base plate 6 and the slider 5 move downwards together along the guide rail 4 under the action of the electric actuator 3 until the support base plate 6 touches the ground, thereby securing the device in the designated location.

[0030] When you want to move the device, energize the electric push rod 3 to retract it. At this time, the support base plate 6 and the slider 5 move upward together along the guide rail 4, the support base plate 6 is lifted off the ground and suspended below the chassis 1. The device can then be moved using the casters 2.

[0031] In summary, the electric actuator 3 provides power and determines the direction of movement of the support base plate 6, while the sliding guide device controls the direction of movement of the support base plate 6. Furthermore, since the movement gap of the slider-guide rail combination is typically at the micrometer level or even zero, precise movement clearance and stable support effects can be guaranteed. In addition, the support base plate 6 can achieve a large contact area with the ground, thereby providing high friction to ensure equipment stability.

[0032] Therefore, the chassis system design of this utility model uses only one electric push rod and a simple slider-guide rail combination. Other structural components are simple machined parts or common fasteners (screws or combinations of screws and nuts). Therefore, the chassis system of this utility model not only has fewer parts and lower cost, but also has good support effect and has better application value.

[0033] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved thereon. The structures described in the embodiments can be freely combined without causing any conflict in structure or principle.

[0034] After a detailed description of the preferred embodiments of the present invention, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the appended claims, and that the present invention is not limited to the embodiments described in the specification.
