Description

TECHNICAL FIELD

[0001] The utility model belongs to the automobile technical field, concretely relates to a hidden tailgate opening limiting device. BACKGROUND

[0002] In vehicle design, especially for the vehicle model with double-side opening tailgate, the opening angle of the tailgate has a significant influence on the access channel of passengers and goods and the surrounding space layout. In theory, if the tailgate can be rotated to open to 270° and keep the minimum gap with the vehicle side, the space can be maximized and the convenience can be improved. However, in practical application, most of the passenger and goods vehicles equipped with double-side opening tailgate also have a vehicle side sliding door.

[0046] In order to better understand the above technical scheme, the above technical scheme will be described in detail below with reference to the drawings and specific embodiments.

[0047] Embodiment:

[0048] As shown in Figures 1 to 6 The utility model discloses a hidden tailgate opening limiting device for accurately positioning and locking tailgate and avoiding random movement, which comprises a vehicle compartment 1, a double-side opening tailgate 2 and two limiting structures 3.

[0049] The vehicle compartment 1 is in a box structure and serves as the main structure of the vehicle.

[0050] The double-side opening tailgate 2 is installed at the tail end of the vehicle compartment 1 and has two independent door plates 201, and a hidden groove 2011 is formed on the outer side of each door plate 201 to accommodate and hide part of the limiting structure 3, so as to maintain the neat appearance of the tailgate when it is closed.

[0051] Two limiting structures 3 are arranged on both sides of the compartment 1, for providing stable limiting support when the tail door is opened.

[0052] Each limiting structure 3 comprises a retractor 301, a low-foot limiting block 302, a high-foot limiting block 303, an elastic reset member 304, a connecting rod mechanism 305, and a pull wire 306, which are specifically arranged as follows:

[0053] The retractor 301 is installed inside the side plate of the compartment 1, between the outer panel and the interior trim panel, and is not exposed, so as to avoid interference from external factors and improve long-term use stability, and is responsible for winding and unwinding the pull wire 306 to control the action of the high-foot limiting block 303.

[0054] The low-foot limiting block 302 is installed on the outer side of the compartment 1, as a limiting point when the tail door is opened to the maximum angle.

[0055] The high-foot limiting block 303 is hinged in the hidden groove 2011, and can cooperate with the low-foot limiting block 302 after the tail door is opened to achieve stable limiting of the tail door, and its shape and size are matched with the hidden groove 2011 to ensure the hiding effect.

[0056] The elastic reset member 304 is installed in the hidden groove 2011 and connected with the high-foot limiting block 303, for automatically resetting the high-foot limiting block 303 to a hidden state when the tail door is closed.

[0057] The connecting rod mechanism 305 is installed inside the door panel 201 and covered by the panel and the interior trim panel, so as to avoid interference from external factors and improve long-term use stability, and is drivingly connected with the high-foot limiting block 303, for realizing extension and retraction of the high-foot limiting block 303 through driving action.

[0058] The pull wire 306 is constrained inside the door panel 201 and the compartment 1, with one end wound in the retractor 301 and the other end connected with the connecting rod mechanism 305, and can control the action of the connecting rod mechanism 305 to control the extension and retraction of the high-foot limiting block 303, and at the same time, the pull wire 306 is constrained inside the door panel 201 and the compartment 1 to ensure the stability and reliability of its movement.

[0059] The above technical solution has the following working principle:

[0060] In the closed state of the tail door, the high-foot limiting block 303 is in a hidden state under the action of the elastic reset member 304, i.e. embedded in the hidden groove 2011, so as to realize hiding, so as to keep the outer side of the door panel 201 clean and flat.

[0061] During the opening process of the tail gate, the pull wire 306 is pulled to make the winding device 301 release the pull wire 306 and generate a pulling force greater than the elastic reset member 304, so that the pull wire 306 pulls the connecting rod mechanism 305, and the connecting rod mechanism 305 drives the high-foot limiting block 303 to rotate, thereby protruding the door plate 201 to the working state.

[0062] During the closing process of the tail gate, the winding device 301 reclaims the pull wire 306, the pull wire 306 no longer generates a pulling force, and then the elastic reset member 304 drives the high-foot limiting block 303 to reset, and then the high-foot limiting block 303 rotates to reset to the hidden state.

[0063] When the tail gate is opened to the limit position, the high-foot limiting block 303 protruding the door plate 201 to the working state is connected with the corresponding low-foot limiting block 302, thereby completing the positioning and locking of the tail gate.

[0064] The utility model discloses a tail gate opening drives the pull wire 306 to generate displacement, makes the winding device 301 release the pull wire 306 and generate the pulling force greater than the elastic reset member 304, thereby through connecting rod mechanism 305 drive high-foot limiting block 303 rotates, make it from hidden recess 2011 rotate to protruding door plate 201, contrarily when closing, winding device 301 reclaim the pull wire 306, let elastic reset member 304 drive high-foot limiting block 303 reset, thus realized the stable limiting function of tail gate in the opening process, effectively reduced the external protruding of vehicle, improved the external modeling, guaranteed the fluent nature and overall aesthetic feeling of vehicle appearance, and excluded the security risk.

[0065] In some embodiments, as shown in Figures 3 to 4 The hinge end of the high-foot limiting block 303 is provided with a containing groove 3031 inside, which is used for accommodating and protecting the key components, and the containing groove 3031 is provided with a vertical hinge shaft 3032, which penetrates the high-foot limiting block 303 and is connected with the hidden recess 2011.

[0066] The containing groove 3031 and the hinge shaft 3032 are arranged to realize the stable hinge connection of the high-foot limiting block 303 with the hidden recess 2011, which provides reliable limiting support for the stable opening of the tail gate, improves the stability and safety of the tail gate opening, and maintains the neatness and beauty of the vehicle appearance.

[0067] On the basis of the above-mentioned embodiments, as shown in Figure 4As shown, the elastic reset member 304 is a torsion spring, which can realize the reset function through the restoring force generated by its torsion, the torsion spring is arranged in the accommodating groove 3031 and is sleeved on the hinge shaft 3032, effectively utilizing the space, improving the structural compactness, also ensuring the stability and durability, and is constrained between the door panel 201 and the high-foot limiting block 303, ensuring that the torsion spring can stably play a role in the process of opening and closing the tail door, providing a reliable power source for the extension and retraction of the high-foot limiting block 303.

[0068] By adopting the torsion spring as the elastic reset member 304 and arranging as described above, the stable reset function of the high-foot limiting block 303 is realized, the smoothness and stability of opening and closing the tail door are improved, the durability of long-term use is ensured, and the neatness and beauty of the vehicle appearance are also maintained.

[0069] In some embodiments, as Figures 3 to 5 As shown, the connecting rod mechanism 305 includes a slide rail 3051, a slide rod 3052 and a pull rod 3053, which are specifically provided as follows:

[0070] The slide rail 3051 is installed inside the door panel 201 to provide a stable sliding path for the slide rod 3052, ensuring that the slide rod 3052 can slide linearly along the predetermined track, improving the stability and durability;

[0071] The slide rod 3052 is linearly slidably connected with the slide rail 3051, and one end is connected with the pull wire 306, which can transmit power to other parts of the connecting rod mechanism 305;

[0072] The pull rod 3053 is hingedly connected at one end with the end of the slide rod 3052 away from the pull wire 306, and at the other end with the high-foot limiting block 303, which can rotate with the sliding of the slide rod 3052, thereby pushing or pulling the high-foot limiting block 303 to realize the extension or retraction action thereof.

[0073] In operation, the pull wire 306 drives the pull rod 3053 to slide linearly along the predetermined track, thereby driving the pull rod 3053 to rotate, which pushes or pulls the high-foot limiting block 303 to rotate, so as to overcome the elastic restoring force of the elastic reset member 304 and rotate the convex door panel 201 to the working state.

[0074] Through the cooperative work of the slide rail 3051, the slide rod 3052 and the pull rod 3053, the pulling force of the pull wire 306 is converted into the extension and retraction action of the high-foot limiting block 303, which improves the smoothness and stability of opening and closing the tail door, also ensures the compactness and reliability of the limiting structure 3, and since the connecting rod mechanism 305 is cleverly hidden inside the door panel 201, the neatness and beauty of the vehicle appearance are also maintained.

[0075] On the basis of the above embodiments, asFigure 1 , Figures 3 to 5 As shown, the limiting structure 3 also includes: multiple fasteners 307, which are installed at intervals inside the door panel 201 and the side panel of the carriage 1, and are fastened to the wire 306.

[0076] Specifically, the fasteners 307 are designed in multiples and are installed at intervals inside the door panel 201 and the side panel of the carriage 1. This not only ensures that the wire drawing 306 is stably supported throughout the entire transmission path, but also improves the strength and durability of the entire limiting structure 3.

[0077] Specifically, each fastener 307 is snap-fitted to the wire 306, which is not only simple and reliable, but also easy to install and disassemble, providing convenience for the maintenance and replacement of the device, and ensuring that the wire 306 can be firmly fixed, thereby avoiding loosening or falling off during the transmission process.

[0078] In addition, the design of the fastener 307 also takes into account the protection of the wire drawing 306, which can prevent the wire drawing 306 from being excessively worn or squeezed during transmission, thereby extending its service life. It can also guide the wire drawing 306 to ensure that it is transmitted along a predetermined path, thereby improving accuracy and reliability.

[0079] By setting the fastener 307, not only is the necessary support and guidance provided for the wire drawing 306, but the strength and durability of the entire limiting structure 3 are also improved; at the same time, it also plays a role in protecting and guiding the wire drawing 306, thereby ensuring the stability and reliability of the entire device.

[0080] In some embodiments, such as Figure 2 As shown, the top of the short-leg limiting block 302 is provided with an insertion hole 3021 that is compatible with the high-leg limiting block 303.

[0081] Specifically, the shape, size, and position of the insertion hole 3021 are carefully designed to ensure a perfect fit with the high-leg limit block 303. When the tailgate is opened to a certain angle, the high-leg limit block 303 extends under the drive of the linkage mechanism 305 and the wire puller 306 and accurately inserts into the insertion hole 3021 of the low-leg limit block 302; this insertion action limits further opening of the tailgate and provides additional stability and safety.

[0082] By setting the socket 3021, the connection between the high foot limit block 303 and the low foot limit block 302 is made more secure and reliable. Even if the vehicle shakes or vibrates, it can ensure that the high foot limit block 303 can be firmly held in the socket 3021, thereby avoiding the risk of the tailgate accidentally loosening.

[0083] In some embodiments, the high foot limiting block 303 is provided with a metal piece in the limiting end, and the low foot limiting block 302 is provided with a magnetic piece at the top end.

[0084] When the high foot limiting block 303 extends to be close to the low foot limiting block 302, the magnetic attraction force between the metal piece and the magnetic piece can further stabilize the connection of the two, prevent loosening or disconnection caused by vibration or shaking, simplify the docking process, improve the docking efficiency, and provide additional fixing effect and improve the locking effect.
