DETAILED DESCRIPTION

[0043] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further detailed in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model, that is, the described examples are only a part of the examples of the utility model, but not all the examples. The components of the utility model embodiments described and shown in the drawings herein can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0045] The features and performance of the utility model will be further described in detail in combination with the examples below.

[0046] Embodiment 1 of the hidden automobile displacement device of the utility model:

[0047] As Figures 1-8 shown, the device comprises a walking support, which is a folding-unfolding type walking support. "Folding-unfolding" means that the walking support has a folding state and an unfolding state. When not in use, it can be folded together and hidden under the vehicle body, and when in use, it can be unfolded for moving the vehicle.

[0048] As shown in Figure 6 , the walking support frame includes a connecting frame 12 (which can also be formed by a part of the vehicle body) and a front support leg 13 and a rear support leg 13' arranged on the connecting frame 12. In this embodiment, the connecting frame is divided into two parts, which are used to connect the left and right sides of the vehicle body, respectively. The front support leg 13 and the rear support leg 13' are both folding support legs. The upper end of the front support leg 13 is hingedly connected to the connecting frame 12 through the upper end of the first hinge shaft 11, and the upper end of the rear support leg 13' is hingedly connected to the connecting frame 12 through the second hinge shaft 11'. The folding and unfolding can be achieved by swinging around the hinge points. The lower end is provided with a walking wheel. In this embodiment, the walking wheel is a bearing. The walking wheel on the front support leg 13 is a front roller 10, and the walking wheel on the rear support leg 13' is a rear roller 10'. In order to ensure the stability of the front and rear support legs after unfolding, the upper end of the front and rear support legs is provided with an angle limiting structure for cooperating with the connecting frame 12 to limit the angle of the support leg. In this embodiment, the angle limiting structure on the front support leg 13 is specifically composed of the front support leg upper end surface 14, and the angle limiting structure on the rear support leg 13' is specifically composed of the rear support leg upper end surface 14'. Therefore, the hinge points of the front and rear support legs and the connecting frame are all arranged on the side of the upper end (in the radial direction of the hinge shaft).

[0049] In this embodiment, the front support leg 13 is folded forward, and the rear support leg 13' is folded backward. In order to achieve automatic folding and unfolding of the front and rear support legs, the front and rear support legs are provided with folding and unfolding driving devices. In this embodiment, the folding and unfolding driving device is specifically a driving oil cylinder 8. One end of the driving oil cylinder 8 is connected to the front support leg 13 through the first connecting pin shaft 9, and the other end is connected to the rear support leg 13' through the second connecting pin shaft 9'. The contraction of the driving oil cylinder 8 can drive the front and rear support legs to unfold, and the front and rear support legs can lift the vehicle body after unfolding. The extension of the driving oil cylinder 8 can drive the front and rear support legs to switch to the folded state.

[0050] In order to provide support to the walking support frame and enable it to walk on various road conditions (ditches, bumps, soft beaches), the walking support frame is connected with a support pillow rail. The support pillow rail is connected with the walking support frame, that is, they have a direct or indirect linkage relationship. When the walking support frame is unfolded, the support pillow rail will fall to the ground and support the walking support frame accordingly. When the walking support frame is folded, the support pillow rail will be folded and hidden accordingly. The structure of the support pillow rail is shown in Figures 3-5 , which can be simultaneously referred to in Figure 1 , 2The support sleeper rail is telescopic, and in the embodiment, the support sleeper rail comprises a first section and a second section. The first section and the second section are in the shape of a U with an inner flange. The second section is inserted into the first section, and the first section is referred to as an outer rail 1 and the second section is referred to as an inner rail 1' herein. In the embodiment, the inner rail and the outer rail are in sliding fit. The outer rail 1 is provided with an outer rail rear limiting point 6 (specifically, a limiting pin), an outer rail front limiting point 7, an outer rail rear traction rope end fixing point 2" and an outer rail front traction rope end fixing point 3". The inner rail 1' is provided with an inner rail front limiting point 6', an inner rail rear limiting point 7', an inner rail front traction rope end fixing point 4" and an inner rail rear traction rope end fixing point 5". The outer rail rear limiting point 6, the outer rail front limiting point 7, the inner rail front limiting point 6' and the inner rail rear limiting point 7' are in fit, so that the inner rail and the outer rail are in anti-disengagement fit. The walking wheel of the walking support is clamped in the slot of the inner rail 1', and is blocked by the flange at the opening of the inner rail 1', so that the walking wheel cannot disengage.

[0051] As shown in FIGS. Figure 1 , 2 , 6, in order to realize the telescoping of the support sleeper rail, the support sleeper rail is provided with a telescoping driving device. In the embodiment, the telescoping driving device is a rope traction driving device, which realizes the lengthening and shortening of the support sleeper rail through rope traction. The rope traction driving device comprises a rope winding device and a pulley block. The rope winding device is a winch (electric winch). The winch has two, which are a first winch 23 and a second winch. The first winch 23 is provided with a first traction rope 2 and a second traction rope 3 which are wound in opposite directions. The first traction rope 2 is connected to the outer rail rear traction rope end fixing point 2", and the second traction rope 3 is connected to the outer rail front traction rope end fixing point 3". The first traction rope is provided with a first redirection pulley 2' on the front leg 13, and the second traction rope 3 is provided with a second redirection pulley 3' on the rear leg. The second winch is connected to a third traction rope 5, and the third traction rope 5 is connected to the inner rail rear traction rope end fixing point 5" of the inner rail. The third traction rope 5 is provided with a third redirection pulley 5' on the front leg 13.

[0052] Through the above structure, when the first winch 23 rotates, the rear end of the outer rail 1 will be pulled forward with the first redirection pulley 2' as a fulcrum, so that the outer rail 1 is extended forward. At the same time, since the second traction rope 3 is wound on the first winch 23 in the opposite direction synchronously with the first traction rope 2, the second traction rope 3 will be automatically and synchronously released by a corresponding length during the forward movement of the outer rail 1. When the walking support moves forward and the inner rail 1' needs to be retracted forward, the third traction rope 5 is pulled by the second winch, and the rear end of the inner rail 1' is pulled forward with the third redirection pulley 5' as a support point. At this time, the first winch 23 is in a dragged state, which is realized through a clutch between the first winch 23 and the corresponding motor.

[0053] To achieve automatic movement of the vehicle body, the traveling support is equipped with a traveling drive mechanism. In this embodiment, the traveling drive mechanism includes a traveling drive device and a traveling transmission mechanism that is connected between the traveling drive device and the traveling support. Specifically, the traveling drive device is also the second winch mentioned above, and the traveling transmission mechanism adopts a movable pulley mechanism. The movable pulley mechanism includes a movable pulley 4' mounted on the second support leg 13' and a fourth traction rope 4 connected to the second winch, with a winding direction opposite to that of the third traction rope 5. The fourth traction rope 4 is connected to the fixed point 4" at the front end of the inner guide rail. Therefore, when the second winch rotates, it can drive the traveling support forward. At the same time, the third traction rope 5 is released synchronously to adapt to the movement of the traveling support.

[0054] In order to tension the first, second, third, and fourth traction ropes, and to allow the system a certain degree of freedom, in this embodiment, each of the first, second, third, and fourth traction ropes is equipped with a tension wheel assembly 15, such as... Figure 7 As shown, the tension wheel assembly 15 includes a compression spring 17, a guide rod, and a rope wheel 16. During use, the compression spring 17 can be compressed to accommodate small changes in the length of the traction rope.

[0055] like Figure 8 As shown, the operation of the concealed car displacement device of this utility model is as follows: Under normal conditions, the walking bracket is folded and hidden at the bottom of the vehicle body. When the car encounters difficulties while moving, the front and rear outriggers can be extended to a certain angle by first retracting the drive cylinder 8. At this time, the outer guide rail 1 is extended forward by the first winch 23, and the inner and outer guide rails will form the walking support of the walking bracket. After the outer guide rail 1 is extended to its full length, the front and rear outriggers are further extended by the drive cylinder 8. At this time, the vehicle body is lifted, and the entire weight of the vehicle body is borne by the walking bracket. Then, start the second winch and simultaneously disengage the clutch of the first winch 23. The second winch will then pull the traveling bracket along the telescopic sleeper rail via the fourth traction rope 4, using the fixed point 4' at the front end of the inner guide rail as the fulcrum. Once the traveling bracket is in position, the front and rear outriggers are folded by the drive cylinder 8, and the inner guide rail 1' can be pulled back by the second winch and the third traction rope 5. Of course, in some scenarios, the outer guide rail can also be extended backward as needed to move the vehicle backward to get out of trouble. In this case, only the rotation direction of the first and second winches needs to be adjusted.

[0056] Embodiment 2 of the concealed vehicle displacement device of this utility model:

[0057] In Embodiment 1 of the concealed vehicle displacement device of this utility model, the two parts of the connecting frame of the traveling bracket are independent of each other. In this embodiment, unlike Embodiment 1, as... Figure 9As shown, the connecting frame of the walking support is connected as a whole structure through a cross beam, and a rotary driving mechanism is arranged on the cross beam, and the rotary driving mechanism is used to drive the walking support to rotate relative to the vehicle body, so that two functions can be realized: 1. When the vehicle body is jacked up, the vehicle body can be turned at the original position or 360 degrees; 2. Before the vehicle body is jacked up, the walking support can be driven to rotate relative to the vehicle body, and after the vehicle body is jacked up, the lateral translation of the vehicle body can be realized, so that the vehicle can be parked laterally. In the embodiment, the rotary driving mechanism comprises a connecting shaft 18 arranged at the center position of the walking support, and an external gear 19 arranged outside the connecting shaft 18, so that the shaft sleeve can be driven to rotate. During rotation, the smaller winding amount of each traction rope is compensated by the tension wheel assembly 15.

[0058] Embodiment 3 of the hidden automobile displacement device of the utility model:

[0059] In the embodiment 2 of the hidden automobile displacement device of the utility model, the expansion and folding of the walking support is realized through the folding and unfolding of the front and rear supporting legs under the action of the driving oil cylinder. In this embodiment, unlike the embodiment 2, the front and rear supporting legs in this embodiment are non-folding supporting legs, and the driving oil cylinder arranged for the front and rear supporting legs is omitted accordingly; as shown, Figure 10 As shown, a push-pull hydraulic oil cylinder 20 perpendicular to the ground is arranged on the connecting frame, and the folding and unfolding of the walking support and the lifting of the vehicle body are realized through the extension and contraction of the push-pull hydraulic oil cylinder 20. The flange plate 21 on the push-pull hydraulic oil cylinder 20 is connected to the center position of the vehicle body, the flange plate 21 on the body of the hydraulic oil cylinder 20 is sleeved with a rotatable external gear 19 at the lower part, two anti-rotation rods 22 penetrating through the external gear 19 are arranged on the cross beam, when the vehicle body is lifted to a certain height by the hydraulic oil cylinder 20 (the extension amount of the traction rope is provided by the extension and contraction of the tension wheel assembly 15), at this time, the upper end of the anti-rotation rod 22 moves downward to the lower part of the flange plate 21 and is located in the external gear 19, that is, the mutual locking of the vehicle body and the telescopic pillow rail is released, and the external gear 19 is driven to rotate, which can drive the telescopic pillow rail to rotate with the center of the hydraulic oil cylinder as the rotation axis, when the rotation angle is 90 degrees, the vehicle can be further jacked up by the hydraulic oil cylinder 20, and then the lateral parking of the vehicle can be realized through the cooperation of the walking support and the telescopic pillow rail, and the traction rope is extended and contracted by the tension wheel assembly 15 to provide a smaller winding extension amount.

[0060] Embodiment 4 of the hidden automobile displacement device of the utility model:

[0061] In the embodiment 1 of the hidden automobile displacement device of the utility model, the expansion and folding of the walking support is realized through the folding and unfolding of the front and rear supporting legs under the action of the driving oil cylinder.
