[0041] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0042] Specific structure such as Figures 1 to 5 shown.

[0043] The present embodiment provides a luggage restraint device, which is arranged on the bottom wall of the luggage compartment 1 of a passenger car and is used to restrain the luggage in the luggage compartment 1. The luggage restraint device includes: a guardrail 2 and a pair of bases 3; the guardrail 2 includes a restraint portion 4 and a connection portion 5, both ends of the restraint portion 4 have a connection portion 5, and the connection portion 5 is bent relative to the restraint portion 4; the base 3 is used to be connected to the bottom wall of the hatch of the luggage compartment 1, and a card slot 6 and a vertical long hole 7 are provided on the base 3, the card slot 6 and the vertical long hole 7 are spaced laterally, and the card slot 6 is higher than the vertical long hole 7, and the vertical long hole 7 has a first rotation area and a second rotation area. area, and the first rotation area is higher than the second rotation area; the end of the connecting part 5 away from the constraint part 4 is hinged to the vertical long hole 7 through the first hinge assembly 8, and the first hinge assembly 8 can move between the first rotation area and the second rotation area, and the end of the connecting part 5 close to the constraint part 4 is connected with the second hinge assembly 9, and a limiting portion 10 is arranged in the slot 6; when the first hinge assembly 8 is located in the first rotation area, the second hinge assembly 9 can enter and exit the slot 6, and when the first hinge assembly 8 is located in the second rotation area, the limiting portion 10 can limit the second hinge assembly 9 from entering and exiting the slot 6.

[0044] In this embodiment, the guardrail 2 can be fixed to the bottom wall of the hatch of the luggage compartment 1 through a pair of bases 3, and the guardrail 2 can be flipped relative to the pair of bases 3 through the first hinge shaft assembly 8. When the first hinge shaft assembly 8 is located in the second rotation area and the first hinge shaft is located in the slot 6, the limiting portion 10 limits the second hinge shaft from exiting the slot 6. At this time, the guardrail 2 is in a self-locking state, and even if the restraining portion 4 is impacted, it will not move, which can effectively restrain the items in the luggage compartment 1. When it is necessary to release the self-locking state of the guardrail 2, it is only necessary to lift the restraining portion 4 upwards, so that the first hinge shaft assembly 8 is raised from the second rotation area to the first rotation area, and the restraining portion 4 is flipped outwards to make the second hinge shaft assembly 9 exit the slot 6 until The constraint part 4 is flipped to the outside of the hatch of the luggage compartment 1 and then put down the constraint part 4, so that the first hinge shaft assembly 8 falls back from the first rotation area to the second rotation area. At this time, the guardrail 2 is in the open state, and items can be taken in and out. After taking and putting in, since the constraint part 4 is located outside the hatch of the luggage compartment 1, the door cannot be closed. It is necessary to lift the constraint part 4 to make the first hinge shaft assembly 8 rise from the second rotation area to the first rotation area, and then flip it into the luggage compartment 1 to make the second hinge shaft assembly 9 enter the slot 6, and then put down the constraint part 4 to make the first hinge shaft assembly 8 fall back from the first rotation area to the second rotation area, and return to the self-locking state. At this time, the door can be closed to achieve active protection. At the same time, the overall structure is simple, the operation is convenient, and the efficiency is high.

[0045] In the optional technical solution of this embodiment, the limiter 10 is located at the notch of the slot 6 near the vertical long hole 7. This allows the second hinge assembly 9 to have a large amount of movement in the slot 6, and has a certain buffering effect when the guardrail 2 is impacted, thereby preventing the guardrail 2 from being damaged.

[0046] However, the present embodiment is not limited thereto, and may also be located below the notch, as long as the position limiting function can be satisfied.

[0047] In the optional technical solution of this embodiment, the slot 6 is arc-shaped along the depth direction of the slot 6. Since the guardrail 2 is switched between the self-locking state and the open state by flipping, the motion trajectory of the second hinge shaft assembly 9 during the flipping of the guardrail 2 is an arc, and the slot 6 is arranged in an arc shape, which is more matched with the motion trajectory of the second hinge shaft assembly 9, and the slot 6 has a better limiting effect on the second hinge shaft assembly 9.

[0048] In the optional technical solution of this embodiment, along the depth direction of the card slot 6, the card slot 6 is straight and inclined relative to the vertical long hole 7. That is, the card slot 6 is an oblique slot, and the width of the oblique slot needs to be able to meet the entry and exit of the second hinge shaft assembly 9, which also has a good limiting effect.

[0049] In the optional technical solution of this embodiment, the base 3 includes a bottom plate 11 and a pair of hinged plates 12 arranged on the bottom plate 11; the bottom plate 11 is used to be connected to the bottom wall of the hatch of the luggage compartment 1; the hinged plate 12 is provided with a card slot 6 and a vertical long hole 7, the end of the connecting part 5 away from the constraint part 4 is hinged between the pair of vertical long holes 7 through the first hinge assembly 8, and the end of the connecting part 5 close to the constraint part 4 is correspondingly matched with the pair of card slots 6 through the second hinge assembly 9. The overall structure is simple and the connection is stable. The bottom plate 11 is connected to the bottom wall of the hatch of the luggage compartment 1 by screws 19.

[0050] In the optional technical solution of this embodiment, the first hinge shaft assembly 8 and the second hinge shaft assembly 9 both include a hollow shaft 13 and a bolt 14; an axial hole 15 is provided on the connecting portion 5, and the hollow shaft 13 is passed through the axial hole 15 and connected to the axial hole 15; a thread that cooperates with the bolt 14 is provided in the hollow shaft 13. At this time, the hollow shaft 13 can act as a hinge shaft, or the bolt 14 can act as a hinge shaft, and the head of the bolt 14 can also limit axial movement. The first hinge shaft assembly 8 and the second hinge shaft assembly 9 have a simple structure and low cost. Among them, the hollow shaft 13 is welded or bonded to the axial hole 15.

[0051] In the optional technical solution of this embodiment, the first hinge shaft assembly 8 and the second hinge shaft assembly 9 further include a bushing 16; the bushing 16 is sleeved on the bolt 14 to form a hinge shaft. The bushing 16 acts as a hinge shaft, has good wear resistance, and is easy to replace.

[0052] Specifically, the bushing 16 has a first section 17 and a second section 18 along the axial direction, and the diameter of the first section 17 is larger than the diameter of the second section 18; the first section 17 is located on the side of the hinge plate 12 away from the connecting portion 5, and can limit the axial movement, and the second section 18 forms a hinge axis. At the same time, a groove is provided on the first section 17, and the head of the bolt 14 is located in the groove to avoid being exposed, which is beautiful and prevents interference with the outside.

[0053] In an optional technical solution of this embodiment, the constraint portion 4 is U-shaped, and the relative bending angle between the constraint portion 4 and the connecting portion 5 is greater than 90° and less than 150°.

[0054] In this embodiment, the first rotation area is located at the upper end of the vertical long hole 7, and the second rotation area is located at the lower end of the vertical long hole 7, which is convenient for operation, but is not limited to this. The first rotation area can be any position higher than the second rotation area, and the inner bottom wall of the slot 6 is higher than the second rotation area. When the guardrail 2 is in the self-locking state, the connecting part 5 is inclined, and the relative bending angle between the constraint part 4 and the connecting part 5 is set to be greater than 90° and less than 150°, so that when the guardrail 2 is in the self-locking state, the constraint part 4 is in a vertical state, and the constraint effect is better.

[0055] The present embodiment provides a passenger car, including the luggage restraint device described above. Therefore, the technical advantages and effects achieved by the passenger car include the technical advantages and effects achieved by the luggage restraint device described above, which will not be described in detail here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
