Description

Technical Field

[0001] The present application relates to the technical field of automotive parts, and particularly relates to a slide rail assembly and a vehicle. Background Art

[0002] With the improvement of people's loading requirements, the space design of the automobile trunk is getting larger and larger. However, most of the existing trunks are not provided with a luggage fixing mechanism. When the vehicle accelerates, decelerates, turns or brakes suddenly during driving, the luggage in the trunk is likely to shake, topple or even flip back and forth and hit the vehicle body, which is likely to cause damage to the luggage or the vehicle body.

[0003] In order to prevent the luggage from rolling and flipping in the trunk, the prior art discloses a luggage fixing mechanism, including two parallel slide rails. Fixed supports are connected to both ends of the slide rails. A partition baffle is arranged between the two slide rails. Both ends of the partition baffle are connected to the fixed supports to be slidably connected to the corresponding side slide rails respectively. A stopper is arranged on one side of the fixed support to limit the sliding of the partition baffle along the slide rail. By dividing the automobile trunk into two completely independent spaces, it is possible to prevent luggage with a small size or a thin thickness from sliding in the automobile trunk. However, the stopper for limiting the sliding of the partition baffle along the slide rail is realized by configuring a locking bolt and tightening the locking bolt, which has problems such as inconvenient operation and stuck cooperation.

[0034] It should also be noted that the first direction mentioned in this embodiment refers to the length direction of the slide rail body, the second direction refers to the width direction of the slide rail body, and the third direction refers to the height direction of the slide rail body. The axial direction mentioned in this embodiment refers to the central axis direction of the pin shaft or through hole, and the axial direction coincides with the third direction; the circumferential direction mentioned in this embodiment refers to the circumferential direction around the central axis of the pin shaft or through hole.

[0035] As Figures 1 to 6As shown in the figure, this embodiment provides a slide rail assembly, including a slide rail body 1, a slide seat body 2, a locking pin 3 and an elastic element 4. The slide rail body 1 is provided with a guiding groove 11 extending along a first direction S1 and opening outward. A plurality of groups of limiting teeth 12 are provided on the relative inner sides of the guiding groove 11 in a second direction S2, and the plurality of limiting teeth 12 are distributed along the first direction S1. The slide seat body 2 is slidably connected to the slide rail body 1 and moves along the guiding groove 11. The slide seat body 2 defines a receiving cavity 21, and a through hole 211 penetrating the bottom of the slide seat body 2 is provided at the bottom of the receiving cavity 21. The locking pin 3 is circumferentially rotatable and axially movable in the receiving cavity 21, and one end thereof extends out of the through hole 211 and extends into the guiding groove 11. The locking pin 3 has an unlocking position 222 and a locking position 221 distributed along a third direction S3 relative to the slide seat body 2, and has an unlocking state and a locking state relative to the slide rail body 1. Among them, the first direction S1, the second direction S2 and the third direction S3 are perpendicular to each other in pairs. The locking pin 3 is misaligned with the limiting teeth 12 in the third direction S3 at the unlocking position 222, that is, the height of the end of the locking pin 3 extending out of the through hole 211 is different from that of the limiting teeth 12 in the third direction S3. Furthermore, the locking pin 3 can be rotated to switch between the unlocking state and the locking state. The height of the locking pin 3 at the locking position 221 corresponds to that of the limiting teeth 12 in the third direction S3. At the same time, the width of the end of the locking pin 3 extending into the guiding groove 11 in the second direction S2 is different in the unlocking state and the locking state. Among them, when the locking pin 3 is in the unlocking state, the width of the end of the locking pin 3 extending into the guiding groove 11 in the second direction S2 is smaller than the distance between the limiting teeth 12 on both sides of the guiding groove 11, so as to be able to disengage from the limiting teeth 12 in the unlocking state. When the locking pin 3 is in the locking state, the width of the end of the locking pin 3 extending into the guiding groove 11 in the second direction S2 is greater than the distance between the limiting teeth 12 on both sides of the guiding groove 11, so as to be able to engage with the limiting teeth 12 in the locking state. The elastic element 4 is arranged between the locking pin 3 and the slide seat body 2, and is adapted to reset the locking pin 3 along the third direction S3 to the locking position 221. In this way, when unlocking is required, the locking pin 3 is pressed or pulled by an external force along the third direction S3 to move it to the unlocking position 222, and then the locking pin 3 is rotated to switch it to the unlocking state. Subsequently, the external force applied to the locking pin 3 is released, and the locking pin 3 is reset based on the elastic potential energy of the elastic element 4, and the locking pin 3 is maintained at the locking position 221 in the unlocking state. In the unlocking state, the locking pin 3 can disengage from the limiting teeth 12 so that the slide seat body 2 and the slide rail body 1 can move relative to each other. When locking is required, the locking pin 3 is pressed or pulled by an external force along the third direction S3 to move it to the unlocking position 222, and then the locking pin 3 is rotated in the reverse direction to switch to the locking state. Subsequently, the external force applied to the locking pin 3 is released, and the locking pin 3 is reset based on the elastic potential energy of the elastic element 4 and is maintained at the locking position 221 in the locking state. In the locking state, the locking pin 3 can engage with the limiting teeth 12 to limit and fix the slide seat body 2 on the slide rail body 1, and the operation is convenient and fast.

[0036] Specifically, as Figures 2 to 6As shown, the locking pin 3 includes a pin shaft 31 and a locking portion 32. The pin shaft 31 is rotatable in the circumferential direction and axially movable through the through hole 211. At least a part of the first end of the pin shaft 31 is located in the accommodation cavity 21. The second end of the pin shaft 31 extends out of the through hole 211 and into the guide groove 11, and is connected with the locking portion 32. Wherein, the central axis of the pin shaft 31, the central axis of the through hole 211 and the third direction S3 coincide, and are perpendicular to the first direction S1 and the second direction S2 at the same time. The locking pin 3 has an unlocking position 222 and a locking position 221 distributed along the third direction S3 relative to the sliding seat body 2, and the locking portion 32 has an unlocking state and a locking state relative to the slide rail body 1. Wherein, when the locking portion 32 is in the unlocking state, its width in the second direction S2 is smaller than the distance between the limiting teeth 12 on both sides of the guide groove 11, so as to be able to disengage from the limiting teeth 12 in the unlocking state. When the locking portion 32 is in the locking state, its width in the second direction S2 is larger than the distance between the limiting teeth 12 on both sides of the guide groove 11, so as to be able to engage with the limiting teeth 12 in the locking state. When the locking pin 3 is located at the unlocking position 222, the locking portion 32 and the limiting teeth 12 are misaligned in the third direction S3, that is, the heights of the locking portion 32 and the limiting teeth 12 in the third direction S3 are different. Furthermore, the locking portion 32 can be switched between the unlocking state and the locking state by rotating the pin shaft 31. When the locking pin 3 is located at the locking position 221 and the locking portion 32 is in the locking state, the heights of the locking portion 32 and the limiting teeth 12 in the third direction S3 correspond to each other, and the locking portion 32 is engaged with the limiting teeth 12 to limit and fix the sliding seat body 2 on the slide rail body 1. When the locking pin 3 is located at the locking position 221 and the locking portion 32 is in the unlocking state, the locking portion 32 is disengaged from the limiting teeth 12, that is, the heights of the locking portion 32 and the limiting teeth 12 in the third direction S3 correspond to each other, but they are misaligned in the second direction S2. The locking portion 32 and the limiting teeth 12 have different position degrees in the second direction S2, so that the sliding seat body 2 can slide along the first direction S1 in the guide groove 11. One end of the elastic element 4 is connected to the sliding seat body 2, and the other end is connected to the locking pin 3, and is adapted to reset the locking pin 3 along the third direction S3 to the locking position 221.In this way, the locking pin 3 can axially move and circumferentially rotate on the slide base body 2. When unlocking is required, by externally pressing or pulling the pin shaft 31 to move the locking portion 32 along the third direction S3 to the unlocking position 222, then rotating the pin shaft 31 to drive the locking portion 32 to rotate, so as to switch the locking portion 32 to the unlocking state. Subsequently, the external force applied to the pin shaft 31 is released, and the locking pin 3 resets based on the elastic potential energy of the elastic element 4, and the locking portion 32 is maintained at the locking position 221 in the unlocking state. In the unlocking state, the locking portion 32 can disengage from the limiting teeth 12 so that the slide base body 2 and the slide rail body 1 can move relatively; when locking is required, by externally pressing or pulling the pin shaft 31 to move the locking portion 32 along the third direction S3 to the unlocking position 222, then reversely rotating the pin shaft 31 to drive the locking portion 32 to reversely rotate, so as to switch the locking portion 32 to the locking state. Subsequently, the external force applied to the pin shaft 31 is released, and the locking pin 3 resets based on the elastic potential energy of the elastic element 4, and the locking portion 32 is maintained at the locking position 221 in the locking state. In the locking state, the locking portion 32 can engage with the limiting teeth 12 to limit and fix the slide base body 2 on the slide rail body 1, which is convenient and fast to operate.

[0037] It can be understood that the elastic element 4, as a part providing a force distributed along the third direction S3, can be of a structural type such as a spring, a tension spring or an elastic sheet, etc. The setting range can be inside the accommodation cavity 21 or outside the accommodation cavity 21. The connection relationship can be between the pin shaft 31 and the slide base body 2, or between the locking portion 32 and the slide base body 2. It is adaptively selected according to the design orientation of the locking position 221 and the unlocking position 222 or the application method of the axial force on the pin shaft 31, as long as the locking pin 3 can be axially reset to the locking position 221 along the pin shaft 31.

[0038] For example, Figures 2 to 6As shown, the slider body 2, the accommodation cavity 21, and the locking pin 3 are arranged on the slide rail body 1 along the third direction S3. Among them, the radial cross-sectional shape of the pin shaft 31 of the locking pin 3 can be designed as a circle, and the through hole 211 is designed as a corresponding circle so that the locking pin 3 can be rotatably arranged in the through hole 211 along the circumferential direction and can move along the third direction S3; the locking portion 32 of the locking pin 3 can be formed into a rectangular block, and the distance between the two ends in the length direction of the rectangular block can be designed to be able to correspond and engage with the limiting teeth 12 on both sides of the guide groove 11 to achieve limitation, while the distance between the two ends in the width direction of the rectangular block can be designed to be smaller than the distance between the two limiting teeth 12 on both sides. In this way, the locking portion 32 has an unlocking state with the length direction parallel to the first direction S1 and a locking state with the length direction parallel to the second direction S2. By rotating the pin shaft 31 along the circumferential direction, the locking portion 32 can be driven to rotate to realize the switching between the unlocking state and the locking state; the lower end surface where the through hole 211 is located is made to correspond to the height of the limiting teeth 12 in the third direction S3, and the radial dimension of the locking portion 32 is designed to be larger than the radial dimension of the through hole 211. In this way, the bottom of the slider body 2 can be used to axially limit the locking portion 32 below the through hole 211 to play a limiting role; at this time, the height position of the lower end surface of the through hole 211 can also be defined as the locking position 221. When the locking portion 32 contacts the bottom of the slider body 2, the locking pin 3 is located at the locking position 221, and the unlocking position 222 is preset to a certain height below the locking position 221 along the third direction S3 so that the locking portion 32 can be offset from the limiting teeth 12 of the slide rail body 1 in the third direction S3 at the unlocking position 222; the elastic element 4 can be a compression spring arranged in the accommodation cavity 21. Compared with setting the elastic element 4 on the side where the locking portion 32 is located, it can protect the elastic element 4 and avoid movement interference between the elastic element 4 and the limiting teeth 12; the compression spring is sleeved on the pin shaft 31 to improve the connection stability of the compression spring; one end of the compression spring is fixedly connected to the pin shaft 31, and the other end abuts against the bottom of the accommodation cavity 21 to provide an upward prestress for the locking pin 3, and further press the locking portion 32 against the lower end surface of the through hole 211 at the bottom of the slider body 2, that is, the locking position 221.Press the pin shaft 31 to move the locking portion 32 downward along the axial direction, i.e., the third direction S3. The compression spring is compressed by an external force and stores elastic potential energy. When the locking portion 32 moves downward to the unlocking position 222, the locking portion 32 is misaligned with the limiting tooth 12 in the third direction S3. At this time, the pin shaft 31 can be rotated to drive the locking portion 32 to rotate and switch to the unlocking state. Then, the external force applied to the pin shaft 31 is released, and the compression spring restores its deformation and releases the elastic potential energy, thereby driving the pin shaft 31 and the locking portion 32 upward along the third direction S3 until the locking portion 32 contacts the lower end surface of the bottom through hole 211 of the slide base body 2, i.e., the locking position 221, and pressing the locking portion 32 in the unlocking state at the locking position 221. In the unlocking state, the length direction of the locking portion 32 is parallel to the first direction S1, and there is no movement interference between the width direction of the locking portion 32 and the limiting tooth 12, and the slide base body 2 and the slide rail body 1 can move relative to each other. After the slide base body 2 reaches the specified position, press the pin shaft 31 to move the locking portion 32 downward along the third direction S3 to the unlocking position 222, rotate the pin shaft 31 to drive the locking portion 32 to rotate and switch to the locking state. Then, release the external force applied to the pin shaft 31, and the compression spring resets and drives the pin shaft 31 and the locking portion 32 upward along the third direction S3 to the locking position 221, and presses the locking portion 32 in the locking state at the locking position 221. In the locking state, the locking portion 32 can be engaged with the limiting tooth 12 to limit and fix the slide base body 2 on the slide rail body 1. Thus, the locking is completed.

[0039] Preferably, the bottom of the accommodating cavity 21 can also be set to have a certain thickness or an installation seat with a certain thickness is provided corresponding to the through hole 211, so that there is a preset space with a certain thickness in the axial direction of the through hole 211. Furthermore, the pin shaft 31 can be axially guided by the side wall of the through hole 211 at the through hole 211, improving the stability of the axial movement of the pin shaft 31 at the through hole 211.

[0040] In some embodiments, such as Figures 1 to 3As shown, the locking pin 3 further includes a limiting portion 33, and the limiting portion 33 is connected to one end of the pin shaft 31 located in the accommodating cavity 21; a limiting groove 22 is formed in the side wall of the accommodating cavity 21, and the limiting portion 33 is movably embedded in the limiting groove 22 and can move circumferentially and in the third direction S3 within the limiting groove 22; since both the limiting portion 33 and the locking portion 32 are connected to the pin shaft 31 and move synchronously with the pin shaft 31, the moving distance of the locking portion 32 in the axial direction is the same as the moving distance of the limiting portion 33 in the axial direction. Therefore, the unlocking position 222 and the locking position 221 of the locking portion 32 can be determined by the position of the limiting portion 33, that is, the two ends of the limiting groove 22 in the third direction S3 can be respectively used as the locking position 221 and the unlocking position 222. By the action of the elastic element 4 on the locking pin 3, the limiting portion 33 can be reset to and held at the locking position 221. By using the switching between the unlocking position 222 and the locking position 221 of the limiting portion 33 in the limiting groove 22, the switching between the unlocking position 222 and the locking position 221 of the locking portion 32 is realized; wherein, the elastic element 4 acts on the locking pin 3, which can be directly applied to the limiting portion 33, thereby reducing the connection structure setting between the pin shaft 31 and the elastic element 4.

[0041] For example, as Figure 2 and Figure 3 shown, in this embodiment, the locking position 221 is arranged at the upper end of the limiting groove 22, and the unlocking position 222 is arranged at the lower end of the limiting groove 22. The elastic element 4 is a compression spring arranged in the accommodating cavity 21. One end of the compression spring abuts against the limiting portion 33, and the other end abuts against the bottom of the accommodating cavity 21, thereby pressing the limiting portion 33 at the locking position 221 at the upper end of the limiting groove 22. At this time, the locking portion 32 and the limiting teeth 12 correspond in height in the third direction S3; pressing the limiting portion 33 to move the limiting portion 33 downward along the limiting groove 22 to the unlocking position 222 at the lower end of the limiting groove 22, the locking portion 32 will move downward synchronously with the limiting portion 33 along the third direction S3 and be displaced from the limiting teeth 12 in the third direction S3, and the state can be switched by rotation.

[0042] In some embodiments, such as Figure 7As shown, since both the limiting portion 33 and the locking portion 32 are connected to the pin shaft 31 and move synchronously with the pin shaft 31, the circumferential rotation range of the locking portion 32 is the same as that of the limiting portion 33. Therefore, the two circumferential ends of the limiting groove 22 can be used as the starting position 223 and the ending position 224 respectively. When the pin shaft 31 is rotated to move the limiting portion 33 circumferentially to the starting position 223, the locking portion 32 rotates accordingly to switch to the unlocked state. When the limiting portion 33 moves circumferentially to the ending position 224, the locking portion 32 switches to the locked state. Among them, the included angle α between the radial connecting line from the starting position 223 to the axis of the pin shaft 31 and the radial connecting line from the ending position 224 to the axis of the pin shaft 31 is 90°. In this way, the rotation angle of the locking pin 3 can be accurately controlled through the limiting groove 22, avoiding the situation that the state of the locking portion 32 cannot be switched properly due to too large or too small rotation amplitude.

[0043] In some embodiments, as Figure 7 shown, the limiting groove 22 further includes at least two limiting sub-grooves 225 that are circumferentially rotationally symmetrically arranged on the side wall of the accommodating cavity 21. The limiting portion 33 includes at least two limiting sub-portions 331 that are arranged on the circumference of the pin shaft 31 corresponding to the limiting sub-grooves 225. Each limiting sub-portion 331 is correspondingly clamped in a limiting sub-groove 225 and can move circumferentially and in the third direction S3 within the corresponding limiting sub-groove 225. By circumferentially rotationally symmetrically arranging each limiting sub-groove 225 and the corresponding limiting sub-portion 331, the locking pin 3 can be evenly stressed in the accommodating cavity 21, making the rotation and movement of the locking pin 3 smoother and more stable.

[0044] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 shown, the slide rail body 1 includes a first guide rail 13. The upper end surface of the first guide rail 13 is provided with a first opening 131 for opening the guide groove 11 to the outside. A first baffle 132 and a second baffle 133 covering the guide groove 11 are respectively arranged on both sides of the first opening 131 in the second direction S2. The first baffle 132 and the second baffle 133 extend along the first direction S1, and a guide gap 134 extending along the first direction S1 is formed between the first baffle 132 and the second baffle 133. When the locking portion 32 is in the unlocked state, the diameter of the locking portion 32 in the second direction S2 is smaller than the width of the guide gap 134. In this way, when the locking portion 32 is switched to the unlocked state, the slide seat body 2 and the locking pin 3 can be loaded and unloaded at any position on the first guide rail 13, avoiding opening a notch for installing the slide seat body 2 on the first guide rail 13 and making the slide rail body 1 more beautiful.

[0045] In some embodiments, as Figure 1 、 Figure 3 and Figure 6As shown, each group of limiting teeth 12 includes a first limiting sub-tooth 121 and a second limiting sub-tooth 122, and the first limiting sub-tooth 121 and the second limiting sub-tooth 122 are symmetrically arranged on the relative inner sides of the first baffle 132 and the second baffle 133; the locking portion 32 is provided with two locking protrusions 321, and the two locking protrusions 321 are rotationally symmetrically arranged about the axis of the pin shaft 31. In this embodiment, the two locking protrusions 321 are respectively arranged on both sides in the length direction of the locking portion 32. When the locking pin 3 is located at the locking position 221 and the locking portion 32 is in the locked state, the locking portion 32 abuts against the lower end surfaces of the first baffle 132 and the second baffle 133, and the two locking protrusions 321 are respectively engaged with the first limiting sub-tooth 121 and the second limiting sub-tooth 122. By symmetrically arranging the first limiting sub-tooth 121 and the second limiting sub-tooth 122 on the relative inner sides of the first baffle 132 and the second baffle 133, the locking position 221 can be set on the upper end surface of the first guide rail 13, and the locking portion 32 can be placed below. The first guide rail 13 is clamped between the locking portion 32 and the slide base body 2 by using the elastic element 4 to improve the connection stability between the slide base body 2 and the slide rail body 1; at the same time, by engaging the two locking protrusions 321 with the first limiting sub-tooth 121 and the second limiting sub-tooth 122 on both sides in the second direction S2, the force on the locking portion 32 can be made uniform, and the stability of the engagement can be improved.

[0046] It can be understood that the engagement between the locking protrusion 321 and the limiting teeth 12 is, in this embodiment, clamped between two adjacent groups of limiting teeth 12 to achieve the purpose of preventing the locking portion 32 and the slide base body 2 from sliding along the first direction S1 on the slide rail body 1.

[0047] In some embodiments, such as Figure 1 and Figure 3 As shown, the slide rail body 1 further includes a second guide rail 14, and the second guide rail 14 covers the first guide rail 13. A second opening 141 corresponding to the first opening 131 is provided on the upper end surface of the second guide rail 14 to expose the guide groove 11 and the guide gap 134 to the outside. In this way, the first guide rail 13 and its limiting teeth 12 can be protected by the second guide rail 14, the probability of the first guide rail 13 and the limiting teeth 12 contacting the outside can be reduced, and the first guide rail 13 and the limiting teeth 12 can be prevented from being damaged by collision.

[0048] In some embodiments, such as Figure 3 and Figure 4As shown, a guiding portion 23 is further provided at the bottom of the sliding seat body 2. The guiding portion 23 is slidably supported on the second opening 141. In this way, the sliding guiding can be realized by the sliding connection between the guiding portion 23 and the second guide rail 14, thereby improving the moving smoothness and connection stability of the sliding seat body 2 on the slide rail body 1. Preferably, in this embodiment, the guiding portion 23 can be correspondingly arranged below the through hole 211 and penetrate the guiding portion 23 through the through hole 211 to increase the designed thickness of the through hole 211. In other embodiments, the guiding portion 23 can also be arranged on both sides of the through hole 211 along the first direction S1, as long as it does not interfere with the rotation of the locking portion 32.
