Description

[0001] Vehicle, connecting mechanism and fixing device

[0002] Technical Field

[0003] This application relates to the field of vehicle-mounted device technology, and in particular to a vehicle, a connection mechanism, and a fixing device for securing the vehicle to a seat in a vehicle.

[0004] Background Technology

[0005] Vehicles, such as pet carriers and storage boxes, are often detachably mounted to vehicle seats using anchoring structures like ISOFIX. Common vehicles are often one-piece designs, with the anchoring structure typically located at the bottom. To ensure the bottom's sturdiness, the bottom is usually made relatively thick and heavy. This results in a relatively large overall weight for the vehicle, making it inconvenient for users to pick up and move.

[0006] Furthermore, the anchoring structure and the vehicle are inseparable, which results in a large overall size and mass of the vehicle, making it inconvenient for users to pick up and move the vehicle.

[0007] Animal caregivers typically use portable vehicles such as pet carriers, pet slings, and pet baskets to transport their animals. When traveling by vehicle, traditional vehicles may not be stably secured to the vehicle seats, causing them to shake, slide, or even fall off the seats during travel, posing safety concerns.

[0008] While some traditional vehicles can be secured to the vehicle's seats using seatbelts, this method is not always stable. For example, when driving on uneven surfaces, a vehicle secured by a seatbelt can still easily wobble relative to the seat. Furthermore, securing the vehicle to the seat requires maneuvering the seatbelt within the confined space of the vehicle, resulting in poor ease of installation and removal.

[0009] Summary of the Invention

[0010] Therefore, it is necessary to provide a carrier that can detach the housing from the base to address the aforementioned technical problems. One aspect of this application provides a carrier comprising: a housing; a base detachably connected to the housing; a locking mechanism disposed in one of the housing and the base; and a locking engagement mechanism disposed in the other of the housing and the base. The locking mechanism is configured to move between a locked position and an unlocked position. In the locked position, the locking mechanism engages with the locking engagement mechanism, and the connection between the housing and the base is locked. In the unlocked position, the locking mechanism disengages from the locking engagement mechanism, and the connection between the housing and the base is unlocked.

[0011] In one embodiment, the locking mechanism includes a movable member movably disposed in one of the housing and the base, and configured to move along a first direction between a locked position and an unlocked position. The locking engagement mechanism includes a locking engagement member fixedly disposed in the other of the housing and the base. In the locked position, the movable member engages with the locking engagement member; in the unlocked position, the movable member disengages from the locking engagement member.

[0012] In one embodiment, a locking portion is provided at the first end of the movable member, the locking portion being fixedly and / or pivotally disposed at the first end. In the locked position, the locking portion engages with a locking engagement member, and in the unlocked position, the locking portion disengages from the locking engagement member.

[0013] In one embodiment, the locking part is provided with a hook, and the locking engagement member includes a slot and / or a lever. When the hook enters the slot and / or the lever, the locking part engages with the locking engagement member. When the hook disengages from the slot and / or the lever, the locking part disengages from the locking engagement member.

[0014] In one embodiment, the locking mechanism further includes a reset member that abuts against a movable member and continuously applies a reset force to the movable member, causing the movable member to always have a tendency to move toward the locked position.

[0015] In one embodiment, the locking mechanism further includes a release member configured such that movement of the release member along a first direction from a first position to a second position drives a moving member to a release position.

[0016] In one embodiment, the release member is provided with a drive groove, and the second end of the movable member is provided with a drive post, which is drawn into the drive groove. When the release member moves from the first position to the second position along the second direction, the drive groove abuts against the drive post, thereby driving the movable member to move towards the release position.

[0017] In one embodiment, the locking mechanism further includes a release retainer configured such that when the movable member is in the release position, the release retainer restricts movement of the movable member in a first direction, and the movable member is held in the release position.

[0018] In one embodiment, the release retainer includes a main body and a limiting part arranged sequentially in the axial direction. The moving part is provided with a limiting hole, and the release retainer is inserted into the limiting hole. When the moving part is in the release position, the limiting part is received in the limiting hole and abuts against the inner wall of the limiting hole, and the movement of the moving part in the first direction is restricted, and the moving part is held in the release position; when the limiting part disengages from the limiting hole, the movement of the moving part in the first direction is allowed.

[0019] In one embodiment, the release retainer further includes a pushing portion extending axially from the limiting portion toward a direction opposite to the main body. The moving member also has a limiting groove extending in a first direction and communicating with a limiting hole, the limiting groove being adapted to receive the pushing portion. The pushing portion drives the release retainer to move upward in a third direction, causing the limiting portion to disengage from the limiting hole. The pushing portion aligns with the limiting groove in the first direction, and movement of the moving member in the first direction is permitted.

[0020] In one embodiment, a limiting perimeter (TT) is further provided between the main body and the limiting part. The limiting perimeter is approximately disc-shaped, with a diameter larger than that of the limiting hole. A retaining reset member is sleeved on the main body. The retaining reset member abuts against the limiting perimeter and continuously applies a reset force to the release retaining member, causing the release retaining member to always tend to press towards the moving member. In one embodiment, the locking mechanism includes a locking mechanism group, which includes a moving member. The moving member includes a first moving member and a second moving member. When the first moving member and the second moving member move away from each other in a first direction, the first moving member and the first moving member move towards the locking position, respectively. When the first moving member and the second moving member move closer to each other in a first direction, the first moving member and the second moving member move towards the release position, respectively. The locking engagement member includes a first locking engagement member adapted to engage with the first moving member; and a second locking engagement member adapted to engage with the second moving member.

[0021] In one embodiment, the locking part includes: a first locking part fixedly disposed at a first end of a first movable member; and a second locking part pivotally disposed at a first end of a first movable member. A first locking engagement member is configured as a slot, which engages with a hook of the first locking part; a second locking engagement member is configured as a lever, which engages with a hook of the second locking part.

[0022] In one embodiment, the movement of the second moving member toward the locking position can drive the second locking part to pivot to the hook position. When the second moving member moves to the locking position, the hook of the locking part hooks onto the lever. The movement of the second moving member toward the unlocking position can drive the second locking part to pivot to the disengaged position. When the second moving member moves to the unlocking position, the hook of the locking part disengages from the lever.

[0023] In one embodiment, the first end of the second moving member is provided with a pivot groove extending along a first direction and a drive groove extending along a third direction. The second locking part is provided with a pivot hole and a drive hole. A pivot pin passes through the pivot groove and the pivot hole, and a drive pin passes through the drive groove and the drive hole. When the second moving member moves between a locked position and an unlocked position along the first direction, the pivot pin moves relative to the second moving member in the pivot groove, and the drive pin moves relative to the second moving member in the drive groove. As the second moving member moves along the first direction, the movement of the drive pin drives the second moving member to pivot around the pivot pin between a hooked position and a disengaged position.

[0024] In one embodiment, the first direction is orthogonal to the third direction.

[0025] In one embodiment, the locking mechanism group further includes: a linkage mechanism, which is connected to the first movable member and the second movable member respectively, and the linkage mechanism is configured to drive the first movable member and the second movable member to move in opposite directions in a first direction.

[0026] In one embodiment, the linkage mechanism includes a first rod, a second rod, a third rod, and a fourth rod. One end of the first rod is pivotally connected to one end of the second rod, and the other end of the first rod is pivotally connected to a first movable member. The other end of the second rod is pivotally connected to a second movable member. One end of the third rod is pivotally connected to the other end of the first rod, and the other end of the third rod is pivotally connected to one end of the fourth rod. The other end of the fourth rod is pivotally connected between the two ends of the second rod, and the fourth rod is configured to pivot about a pivot axis located at the midpoint of the fourth rod.

[0027] In one embodiment, the pivot point of the first rod and the first moving member, the pivot point of the second rod and the second moving member, and the midpoint of the fourth rod are arranged on a straight line parallel to the first direction.

[0028] In one embodiment, the locking mechanism assembly further includes: a release member, configured such that movement of the release member along a first direction from a first position to a second position drives a first moving member and a second moving member to the release position. A pivot shaft is fixedly disposed relative to the base 3, and the release member is provided with a positioning groove extending along a second direction. When the release member moves to the first position, the pivot shaft abuts against one end of the positioning groove, and when the release member moves to the second position, the pivot shaft abuts against the other end of the positioning groove.

[0029] In one embodiment, the unlocking member is provided with a first driving groove and a second driving groove respectively arranged on both sides of the positioning groove. A first driving post is provided at the second end of the first moving member, and the first driving post is inserted into the first driving groove. A second driving post is provided at the second end of the second moving member, and the first driving post is inserted into the second driving groove. When the unlocking member moves from the first position to the second position along the second direction, the first driving groove and the second driving groove abut against the first driving post and the second driving post respectively, thereby driving the first moving member and the second moving member to move towards the unlocking position.

[0030] In one embodiment, the locking mechanism includes two sets of locking mechanism wires, one set of locking mechanism wires being connected to the other set of locking mechanism wires via a linkage configured to transmit tension.

[0031] In one embodiment, the locking mechanism includes two sets of locking mechanism groups, wherein the two ends of the fourth rod of one set of locking mechanism groups are respectively connected to the two ends of the fourth rod of the other set of locking mechanism groups via a linkage, the linkage being configured to transmit tension. In one embodiment, the linkage is a steel wire.

[0032] Another aspect of this application provides a connection mechanism for connecting a vehicle to a mobile device. The connection mechanism includes a locking assembly comprising a locking member, a blocking member, and a linkage member. The locking member is movably configured to be detachably connected to the vehicle. The blocking member is configured to be movable between a blocking position abutting the locking member and a release position disengaging from the locking member. The linkage member is operatively connected to the blocking member, and movement of the linkage member drives the blocking member to move between the blocking position and the release position. When the locking member is in a first locked position, the linkage member is in the first locked position, the blocking member is in the blocking position, and the locking member is locked in the first locked position. When the locking member is in the first locked position, the linkage member moves to a second unlocking position, the blocking member moves to the release position, and the locking member is released from the first locked position.

[0033] In one embodiment, the connecting mechanism further includes a release component, which includes a drive member operably connected to the linkage member, and rotation of the drive member drives the linkage member to move from a second locked position to a second release position.

[0034] In one embodiment, the release assembly further includes an actuating member and a rotating member. The actuating member is operably connected to the rotating member, and a driving member is connected to the rotating member, wherein rotation of the actuating member drives the rotating member to rotate, thereby driving the driving member to rotate.

[0035] In one embodiment, the linkage is operably connected to the blocking member, and movement of the linkage between a second locked position and a second unlocked position drives the blocking member to move between a blocking position and a released position.

[0036] In one embodiment, the locking assembly further includes a locking reset member. The locking reset member abuts against the linkage member, and the locking reset member continuously applies an elastic force to the linkage member, causing the linkage member to tend to move toward a second locking position.

[0037] In one embodiment, the locking assembly further includes a release reset member that abuts against the locking member and continuously applies an elastic force to the locking member, causing the locking member to tend to rotate away from the first locking position.

[0038] In one embodiment, the locking member is provided with a first retaining portion, and the linkage member is provided with a second retaining portion. When the locking member is in the first unlocking position and the linkage member is in the second unlocking position, the first retaining portion abuts against the second retaining portion to apply a pushing force to the linkage member. The pushing force counteracts the tendency of the linkage member to move toward the first locking position, thereby keeping the linkage member in the first unlocking position.

[0039] In one embodiment, the release assembly further includes: a drive seat fixed to the end of the rotating member, the driving member being disposed at the end of the drive seat and extending from the end of the drive seat in a direction away from the drive seat.

[0137] Detailed Implementation

[0138] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can adapt it without departing from the scope of this application.

[0139] Similar improvements can be made under the existing circumstances, therefore this application is not limited to the specific embodiments disclosed below.

[0140] It should be noted that when a feature or element is referred to herein as "on another feature or element," it may be directly on the other feature or element, or there may be intermediate features and / or elements present. Conversely, when a feature or element is referred to as "directly" on another feature or element, there are no intermediate features or elements present. It should also be understood that when a feature or element is referred to as "connected," "attached," or "joined" to another feature or element, it may be directly connected, attached, or joined to the other feature or element, or there may be intermediate features or elements present. Conversely, when a feature or element is referred to as "directly connected," "directly attached," or "directly joined" to another feature or element, there are no intermediate features or elements present.

[0141] While the terms "first" and "first" may be used herein to describe various features or elements, these features or elements should not be limited by these terms unless otherwise specified. These terms may be used to distinguish one feature or element from another. Thus, the first feature or element discussed below may be referred to as the second feature or element, and similarly, the second feature or element discussed below may be referred to as the first feature or element. In this text, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined. Words such as "a" or "one" do not necessarily indicate a quantity limitation. Words such as "including" or "contains" mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects.

[0142] Spatial terms such as “below,” “to the side of,” “above,” and “over” are used herein for descriptive purposes, particularly to describe the positional relationship between one feature or element and another, as shown in the figures. It should be understood that spatial terms are intended to include not only the orientation shown in the figures but also different orientations of the device in use or operation. For example, if the device in the figures is inverted, a feature or element described herein as “below” other features or elements would be oriented as “above” other features or elements. Thus, the exemplary term “below” can include both above and below orientations. The device may also be oriented otherwise (rotated 90 degrees or in other directions), and the spatially related descriptions used herein are interpreted accordingly. Similarly, unless otherwise specified, the terms “upward,” “toward,” “vertical,” and “horizontal” used herein are for illustrative purposes only.

[0143] Referring to Figures 1 and 2, a carrier 1 is provided according to one embodiment of this application. Optionally, the carrier 1 may be a carrying case such as a pet carrier or a storage box, and the user may choose to place items or animals in the carrier 1 as needed; this application does not limit this. The carrier 1 includes a case 2 and a base 3 that are detachably connected to each other. Optionally, the base 3 is provided with an ISOFIX plug 31 for connecting to an ISOFIX slot (not shown) of, for example, a vehicle seat, thereby securing the carrier 1 to the vehicle seat. Optionally, the base 3 may also be provided with a release switch 32 for releasing the ISOFIX plug 31; the user releases the connection between the ISOFIX plug 31 and the ISOFIX slot by operating the release switch 32, thereby releasing the fixed connection between the carrier 1 and the vehicle seat. Optionally, the base 3 may be provided with multiple ISOFIX plugs 31, which are operably connected to a release switch 32 via a pull member 35 (refer to FIG. 10), thereby allowing the release of multiple ISOFIX plugs 31 to be controlled by a single release switch 32.

[0144] In the embodiments shown in Figures 1 and 2, the housing 2 can be locked to the base 3, making them inseparable. The base 3 is also provided with a release mechanism 43, which the user can operate to release the housing 2 from the base 3, thus separating the housing 2 from the base 3. For example, if the vehicle 1 is fixedly connected to the vehicle seat via an ISOFIX connector 31, and it is necessary to remove the vehicle 1 from the vehicle, the user can operate the release mechanism 43 to release the housing 2 from the base 3. In this way, only the housing 2 can be removed from the vehicle without releasing the connection between the ISOFIX connector 31 and the ISOFIX slot, thereby reducing the weight to be taken out and improving the convenience of taking out and carrying.

[0145] For ease of description, the following directional terms are defined. As shown in Figure 1, with the vehicle 1 mounted to the vehicle seat via the ISOFIX connector 31 as a reference, the ISOFIX connector 31 protrudes from the rear side of the vehicle 1. Correspondingly, the side opposite to the rear side is the front side of the vehicle 1. The front-back direction is defined as the first direction D1. The two sides of the vehicle 1 are defined as the left and right sides, and the left-right direction is defined as the second direction D2. The side of the vehicle 1 away from the base 3 is defined as the upper side (i.e., the top side of the housing 2), and the side of the base 3 that contacts the vehicle seat is defined as the lower side of the vehicle 1. The up-down direction is defined as the third direction D3. O For example, the front, side 1' and left side of vehicle 1 can be observed in Figure 1.

[0146] Referring to Figures 3 to 5, optionally, release mechanisms 43 are provided on the left and right sides of the base 3 to facilitate the user releasing the housing 2 from the base 3. The carrier 1 is also provided with a locking mechanism 4 and a locking engagement mechanism 5 that engages with the locking mechanism 4. The locking mechanism 4 is movable between a locked position and an unlocked position. In the locked position, the locking mechanism 4 engages with the locking engagement mechanism...

[0147] 5. Engagement: The connection between the housing 2 and the base 3 is locked. In the unlocked position, the locking mechanism 4 disengages from the locking engagement mechanism 5, and the connection between the housing 2 and the base 3 is unlocked. For example, the locking mechanism 4 includes a hook-shaped first locking part 411 and a second locking part 461, and the locking engagement mechanism 5 includes, for example, a first locking engagement member 51 as a slot (shown in dashed lines in FIG. 5) and a second locking engagement member 52 as a lever. By engaging the first locking part 411 and the second locking part 461 to the slot and the lever respectively, the housing 2 is locked to the base 3. By operating the unlocking member 43, the engagement of the first locking part 411 with the R-slot and the engagement of the first locking part 461 with the R-lever can be released, thereby unlocking the housing 2 from the base 3. This will be explained in more detail below.

[0148] Optionally, the locking mechanism 4 may include only one of the first locking part 411 and the first locking part 461, and the locking engagement mechanism 5 may include only one of the first locking engagement member 51 and the second locking engagement member 52 that can engage with the locking mechanism 4. It should be noted that although the accompanying drawings show the locking mechanism 4 mounted on the base 3 and the locking engagement mechanism 5 not mounted on the housing 2, this is merely exemplary. The locking mechanism 4 and the locking engagement mechanism 5 may also be mounted in opposite positions, i.e., the locking mechanism 4 is mounted on the housing 2 and the locking engagement mechanism 5 is mounted on the base 3. The following description will use the example of the locking mechanism 4 being mounted on the base 3.

[0149] Referring to Figures 3 and 6, in one embodiment of this application, the base 3 includes an upper base cover 33 and a lower base cover 34, forming an installation space between the upper base cover 33 and the lower base cover 34, and the locking mechanism 4 is disposed in this installation space. Referring also to Figures 6 to 9, in one embodiment of this application, the locking mechanism 4 includes a movable member movably disposed on the base 3, for example, a first movable member 41. The first movable member 41 is configured as a generally rod-shaped member and is capable of moving, for example, sliding, between a locked position and an unlocked position along a first direction D1. Optionally, a first locking part 411 is fixedly disposed at the first end of the first movable member 41, and the first locking part 411 has a hook part 411a. The locking engagement mechanism 5 includes a first locking engagement member 51o fixedly disposed on the housing 2. Optionally, the first locking engagement member 51 is configured as a slot. When the first movable member 41 moves to the locked position, the hook part 411a of the first locking part 411 enters the slot. At this time, the first moving part 41 engages with the first locking engagement part 51, and the connection between the housing 2 and the base 3 is locked. When the first moving part 41 moves to the unlocking position, the hook 411a of the first locking part 411 disengages from the slot. At this time, the first moving part 41 disengages from the first locking engagement part 51, and the connection between the housing 2 and the base 3 is unlocked. Optionally, the first locking part 411 can be made of plastic or metal. Optionally, a locking mechanism 4 is provided at approximately the four corners of the base 3, and a locking foot engagement mechanism 5 is provided at the corresponding four corners of the housing 2. When the housing 2 is installed on the base 3, each locking mechanism 4 engages with a locking engagement mechanism 5. Optionally, an unlocking part 43 is provided for each locking mechanism 4.

[0150] Referring to Figures 10 to 14, in one embodiment of this application, the locking mechanism 4 further includes a reset member that continuously applies a reset force to the moving member, causing the moving member to always tend to move toward the locked position. For example, the reset member includes a first reset member 42, one end of which abuts against the first moving member 41, and the other end of which abuts against the base 3. Thus, the first reset member 42 can continuously apply a reset force to the first moving member 41, causing the first moving member 41 to always tend to move toward the locked position. Optionally, the first reset member 42 is made of an elastic material. Optionally, the first reset member 42 is a spring, torsion spring, sheet spring, etc.

[0151] Referring to Figures 8 and 10, in one embodiment of this application, a reinforcing member 49 is fixedly provided on the base 3. The reinforcing member 49 can improve the structural strength of the base 3 and provide stable mounting support for the locking mechanism 4. Optionally, the reinforcing member 49 can be a reinforcing tube. Optionally, a limiting frame 48 is fixedly provided on the base 3, and the first moving member 41 and / or the second moving member 46 are at least partially disposed within the limiting frame 48 and move within the limiting frame 48. Optionally, the limiting frame 48 is fixed to the reinforcing member 49. The limiting frame 48 can, on the one hand, ensure the smooth movement of the first moving part 41 and / or the second moving part 46, and protect the movement stroke of the first moving part 41 and / or the second moving part 46 to prevent foreign objects from entering the movement stroke and obstructing the movement. On the other hand, it can also provide a stable mounting support for the first moving part 41 and / or the second moving part 46. For example, when the vehicle 1 suffers an external impact, the limiting frame 48 can ensure the stable mounting of the first moving part 41 and / or the second moving part 46 to avoid the second moving part 41 and / or the second moving part 46 from moving undesirably.

[0152] Referring also to Figures 11 to 14, in one embodiment of this application, the unlocking member 43 is provided with a driving groove 431, for example, a first driving groove 431a. A driving post 44, for example, a first driving post 441, is provided at the second end of the first moving member 41. The first driving post 441 is inserted into the first driving groove 431a. During the process of the user driving the unlocking member 43 to move along the second direction D2 from the first position to the second position, the first driving groove 431a abuts against the first driving post 441 to drive the first moving member 41 to move along the first direction D1 toward the unlocking position. Optionally, the first driving groove 431a has a driving inclined edge that forms an angle with both the first direction D1 and the second direction D2, and the driving inclined edge abuts against the first driving post 441 to convert the movement of the unlocking member 43 along the second direction D2 into the movement of the first moving member 41 along the first direction D1.

[0153] Referring also to Figures 15 to 18, in one embodiment of this application, the locking mechanism 4 further includes a release retainer 45. When the moving member is in the release position, the release retainer 45 can restrict the movement of the moving member in the first direction D1, thereby holding the moving member in the release position. Optionally, the release retainer 45 includes a main body portion 451 and a limiting portion 453 arranged sequentially in the axial direction. The limiting portion 453 is configured as a generally disc-shaped part. The first moving member 41 is provided with a limiting hole 412, in which the release retainer 45 is inserted. When the first moving member 41 is in the release position, the limiting portion 453 is received in the limiting hole 412 and abuts against the inner wall of the limiting hole 412. At this time, the movement of the first moving member 41 in the first direction D1 is restricted, and the first moving member 41 is held in the unlocked position; when the user drives the limiting part 453 to disengage from the limiting hole 412, the movement of the first moving member 41 in the first direction D1 is allowed, that is, the first moving member 41 can leave the unlocked position and move to the locked position. Optionally, the unlocking retainer 45 also includes a push part 454, which extends axially (e.g., in the third direction D3) from the limiting part 453 toward a direction away from the main body part 451. Optionally, the push part 454 is configured as a generally cylindrical structure. The first moving member 41 is also provided with a limiting groove 413, which extends in the first direction D1 and communicates with the limiting hole 412. The groove width of the limiting groove 413 is greater than the diameter of the push part 454 to accommodate the push part 454. The user can press the push part 454 to move the first moving member 454. The limiting part 453 is driven to disengage from the limiting hole 412. For example, when the housing 2 is installed on the base 3, the bottom side of the housing 2 presses against the push part 454 to drive the limiting part 453 to disengage from the limiting hole 412. At this time, the push part 454 is aligned with the limiting groove 413 in the first direction D1. Since the groove width of the limiting groove 413 is greater than the diameter of the push part 454, the push part 454 can enter the limiting groove 413, and the movement of the first moving member 41 in the first direction D1 is allowed. It should be noted that, with the base 3, such as the base cover 34, as a reference, the release retainer 45 can only move in the third direction D3 so that the limiting part 453 enters or disengages from the limiting hole 412, thereby restricting or allowing the movement of the first moving member 41 in the third direction D1. Optionally, the first direction D1 and the third direction D3 are mutually exclusive.

[0154] Optionally, a limiting edge 452 is provided between the main body 451 and the limiting part 453. The limiting edge 452 is approximately disc-shaped, and its diameter is larger than the diameter of the limiting hole 412. Optionally, a retaining and resetting member 455 is sleeved on the main body 451. The retaining and resetting member 455 abuts against the limiting edge 452, and the retaining and resetting member 455 continuously applies a resetting force to the release retaining member 45, so that the release retaining member 45 always tends to press against the first moving member 41. For example, when the first moving member 41 is in the unlocked position, the retaining reset member 455 drives the unlocking retaining member 45 to move upward in the third direction D3, so that the limiting part 453 enters the limiting hole 412. Because the diameter of the limiting perimeter 452 is larger than the diameter of the limiting hole 412, the limiting perimeter 452 is located below the limiting hole 412 and presses against the inner wall of the first moving member 41. In this way, the limiting part 453 is held in the limiting hole 412. At this time, the pushing part 454 protrudes from the base cover 33 of the base 3. Optionally, the base cover 33 is provided with a through hole 331, and the pushing part 454 protrudes from the base cover 33 through the through hole 331. When the housing 2 is installed on the base 3, the bottom of the housing 2 presses against the pushing part 454, and the locking retainer 45 overcomes the reset force of the retaining reset member 455 and moves downward in the third direction D3, and the limiting part 453 disengages from the limiting hole 412. Under the action of the first reset member 42, the first moving member 41 moves toward the locked position. When the hook 411a of the first locking part 411 enters the slot, the first moving member 41 reaches the locked position, and the connection between the housing 2 and the base 3 is locked. Optionally, the retaining reset member 455 is made of an elastic material. Optionally, the retaining reset member 455 is a spring, torsion spring, spring sheet, etc.

[0155] Referring again to Figures 6 to 9, in one embodiment of this application, the movable member further includes a second movable member 46 movably disposed on the base 3. The second movable member 46 is capable of moving, for example, sliding, between a locked position and an unlocked position along the first direction D1. Optionally, a second locking portion 461, for example in the shape of a hook, is pivotally disposed at the first end of the second movable member 46. The locking engagement mechanism 5 includes a second locking engagement member 52 fixedly disposed on the housing 2. Optionally, the second locking engagement member 52 is configured as a lever. When the first movable member 46 moves to the locked position, the first movable member 46 drives the first locking portion 461 to pivot to the hook position, and the hook portion 461c of the second locking portion 461 hooks the lever. That is, the second movable member 46 engages with the second locking engagement member 52, and the connection between the housing 2 and the base 3 is locked. When the second moving member 46 moves to the unlocked position, it drives the second locking part 461 to pivot to the disengaged position, and the hook 461c of the second locking part 461 disengages from the lever. That is, the second moving member 46 disengages from the second locking engagement member 52, and the connection between the housing 2 and the base 3 is unlocked. Optionally, the second locking part 461 can be made of plastic or metal.

[0156] Referring again to Figure 1. In one embodiment of this application, the reset member further includes a second reset member 47. One end of the second reset member 47 abuts against the second moving member 46, and the other end of the second reset member 47 abuts against the base 3. Thus, the second reset member 47 can continuously apply a reset force to the second moving member 46, causing the second moving member 46 to constantly tend to move towards the locked position. Optionally, the second reset member 47 is made of an elastic material. Optionally, the second reset member 47 is a spring, torsion spring, sheet spring, etc.

[0157] Referring again to Figures 11 to 14, in one example of this embodiment, the drive groove 431 of the release member 43 further includes a second drive groove 431b. A drive post 44, for example, a second drive post 442, is provided at the second end of the second moving member 46. The second drive post 442 is inserted into the second drive groove 431b. During the user's movement of the release member 43 along the second direction D2 from the first position to the second position, the second drive groove 431b abuts against the second drive post 442 to drive the second moving member 46 to move along the first direction D1 toward the release position. Optionally, the second drive groove 431b has a drive slope that forms an angle with both the first direction D1 and the second direction D2. The drive slope abuts against the second drive post 442 to convert the movement of the release member 43 along the second direction D2 into the movement of the second moving member 46 along the first direction D1.

[0158] Referring again to Figures 15 to 18, in one embodiment of this invention, similar to the first moving member 41, the first moving member 46 is also provided with a limiting hole 412, in which a release retainer 45 is inserted. By moving the release retainer 45 in the third direction D1, the second moving member 46 is held in the unlocked position, or allowed to move towards the locked position in the first direction D1. The release retainer 45 according to this embodiment has the same structure and working principle as the release retainer 45 provided in the first moving member 41, and therefore will not be described again.

[0159] Referring also to Figures 20 to 22, in one embodiment according to the application, the first end of the second moving member 46 is provided with a pivot groove 462 extending along a first direction D1 and a drive groove 463 extending along a third direction D3. The second locking part 461 is provided with a pivot hole 461a and a drive hole 461b. By passing a pivot pin 464 through the pivot groove 462 and the pivot hole 461a, and by passing a drive pin 465 through the drive groove 463 and the drive hole 461b, the second locking part 461 is pivotally connected to the first end of the second moving member 46. As the second moving member 46 moves along the first direction D1 between the locked and unlocked positions, the pivot pin 464 moves relative to the second moving member 46 in the pivot groove 462, for example, sliding, and the drive pin 465 moves relative to the second moving member 46 in the drive groove 463, for example, sliding. And as the second moving member 46 moves along the first direction D1, for example, sliding, the actual movement of the drive pin 465 is a pivoting motion about the pivot pin 464. The pivoting of the drive pin 465 drives the second locking foot 461 to pivot about the pivot pin 464 between the hooked and disengaged positions. It should be noted that, taking the base 3, such as the base cover 34, as a reference, when the second moving member 46 moves along the first direction D1 toward the unlocking position, the pivot pin 464 remains stationary, and the drive pin 465 and the second locking part 461 pivot about the pivot pin 464 in the first pivot direction R1 (shown as clockwise in Figure 21). When the second moving member 46 moves along the first direction D1 toward the locking position, the pivot pin 464 remains stationary, and the drive pin 465 and the second locking part 461 pivot about the pivot pin 464 in the second pivot direction R2 (shown as counterclockwise in Figure 22).

[0160] In one embodiment of the application, the locking mechanism 4 may simultaneously include a first moving member 41 and a second moving member 46. For example, the locking mechanism 4 may include a locking mechanism group, which includes a first moving member 41, a second moving member 46, a release member 43, a first reset member 42, a second reset member 47, a release retaining member 45, and a linkage mechanism 61. In such an embodiment, the first moving member 41, the first moving member 46, the release member 43, the first reset member 42, the first reset member 47, the release retaining member 45, and the structures disposed on these devices are the same as in the aforementioned embodiments, and will not be described again here. Optionally, referring to Figures 6 to 9, for example, a locking mechanism group is provided on the left and right sides of the base 3. In such an embodiment, a moving member is provided at approximately the four apex positions of the base 3, wherein a second moving member 46 is provided at the two apex positions located on the rear side of the base 3, and a first moving member 41 is provided at the two apex positions located on the front side of the base 3. Optionally, a release element 43 is provided for each locking mechanism group to drive the first moving member 41 and the second moving member 46 in the locking mechanism group to the release position. Optionally, the first locking part 461 of the second moving member 46 is made of a metal material (e.g., aluminum alloy, steel, etc.); the second locking part 411 of the second moving member 41 is made of plastic. In such an embodiment, the pivotable second locking part 461 is made of a metal material, and the connection between the first locking part 461 and the second locking engagement member 52 is more secure. Therefore, the connection between the housing 2 and the base 3 is more secure, and the housing 2 and the base 3 will not unexpectedly detach when the carrier 1 is impacted. Optionally, both the first locking part 411 of the first moving member 41 and the second locking part 461 of the second moving member 46 are made of metal materials.

[0161] Referring again to Figures 6 to 9, in one embodiment of this application, a locking mechanism group includes a first moving member 41 and a second moving member 46. In the locking mechanism group, the first moving member 41 and the second moving member 46 are arranged along a first direction D1 on the side of the base 3. Optionally, two locking mechanism groups are provided, for example, the left and right sides of the base 3 can be respectively provided. In the locking mechanism group, when the first moving member 41 and the second moving member 46 move toward each other in the first direction D1, the first moving member 41 and the second moving member 46 move toward the unlocked position; when the first moving member 41 and the first moving member 46 move away from each other in the first direction D1, the first moving member 41 and the second moving member 46 move toward the locked position.

[0162] Referring to Figures 8 and 9, the locking mechanism group also includes a linkage mechanism 61, which is connected to the first moving member 41 and the second moving member 46 of the locking mechanism group. When one of the first moving member 41 and the second moving member 46 moves in the first direction D1, the linkage mechanism 61 can drive the other of the first moving member 41 and the second moving member 46 to move in the opposite direction in the first direction D1. That is, the linkage mechanism 61 can drive the first moving member 41 and the second moving member 46 of the same locking mechanism group to move in opposite directions in the first direction D1. By setting the linkage mechanism 61, the first moving member 41 and the first moving member 46 in the same locking mechanism group can only move simultaneously in the first direction D1 in a direction that is closer to or farther from each other.

[0163] In this case, the linkage mechanism 61 is configured as a four-bar linkage. For example, the linkage mechanism 61 includes a first bar 611, a second bar 612, a second bar 613, and a fourth bar 614. One end of the first bar 611 is pivotally connected to one end of the second bar 612, and the other end of the first bar 611 is pivotally connected to a first moving member 41; the other end of the second bar 612 is pivotally connected to a second moving member 46; one end of the third bar 613 is pivotally connected to the other end of the first bar 611, and the other end of the third bar 613 is pivotally connected to one end of the fourth bar 614; the other end of the fourth bar 614 is pivotally connected between the two ends of the second bar 612. A fastening screw 616 is provided at the midpoint 614a of the fourth bar 614, which is fixed to a pivot shaft 615, which is fixed relative to the base 3. The fourth bar 614 can pivot around the pivot shaft 615.

[0164] In such an embodiment, if one of the first moving member 41 and the second moving member 46 is driven to move toward the locked position, the angle α between the first link 611 and the second link 612 will increase under the action of the four-bar linkage. This causes the other of the first moving member 41 and the second moving member 46 to also move toward the locked position, that is, the first moving member 41 and the second moving member 46 will move away from each other along the first direction D1. Similarly, if one of the first moving member 41 and the second moving member 46 is driven to move toward the unlocked position, the angle α between the first link 611 and the second link 612 will decrease under the action of the four-bar linkage. This causes the other of the first moving member 41 and the second moving member 46 to also move toward the unlocked position, that is, the second moving member 41 and the second moving member 46 will move closer to each other along the second direction D1.

[0165] Referring again to Figures 8 and 9, optionally, the pivot point 611a of the first link 611 and the first moving member 41, the pivot point 612a of the second link 612 and the second moving member 46, and the midpoint 614a of the fourth link 614 are arranged on a straight line parallel to the first direction D1. This arrangement makes the operation of the four-bar linkage smoother and more fluid.

[0166] Referring to Figures 13 and 14, optionally, the release member 43 is provided with a positioning groove 432 extending along the second direction D2. A pivot shaft 615 passes through the positioning groove 432. When the release member 43 moves to the first position, the pivot shaft 615 abuts against one end of the positioning groove 432; when the release member 43 moves to the second position, the pivot shaft 615 abuts against the other end of the positioning groove 432. This restricts the travel of the release member 43 to prevent damage to the release member 43 or other structures cooperating with it due to excessive pulling by the user.

[0167] Referring again to Figures 13 and 14, optionally, the release member 43 is provided with a first driving inclined groove 431a and a second driving inclined groove 431b arranged on both sides of the positioning groove 432. A first driving post 441 is inserted into the first driving inclined groove 431a, and a second driving post 442 is inserted into the second driving inclined groove 431b. When the release member 43 moves from the first position to the second position along the second direction D2, the first driving inclined groove 431a and the second driving inclined groove 431b abut against the first driving post 441 and the second driving post 442 respectively, thereby driving the first moving member 41 and the second moving member 46 to move towards the release position. That is, the user can drive the first moving member 41 and the second moving member 46 to move simultaneously towards the release position through the release member 43. In the embodiment with the first driving groove 431a and the second driving groove 431b, the release member 43 can simultaneously abut against the first driving post 441 and the first driving post 442. The driving force applied by the user to the release member 43 can be evenly transmitted to the first moving member 41 and the second moving member 46. Thus, the force on the release member 43, the first moving member 41, and the second moving member 46 is uniform, ensuring the stability of the movement of the release member 43, the first moving member 41, and the second moving member 46. Optionally, the release member 43 may also be provided with only one of the first driving groove 431a and the second driving groove 431b, that is, only one driving groove 431 is provided. Correspondingly, one of the first moving member 41 and the first moving member 46 is provided with a driving post 44 that cooperates with the driving groove 431. In such an embodiment, while the locking member 43 directly drives one of the first moving member 41 and the second moving member 46 to move toward the locking position, the other of the first moving member 41 and the second moving member 46 will also move toward the locking position under the action of the linkage mechanism 61.

[0168] Referring to Figures 6 and 7, in one embodiment of this application, the locking mechanism 4 may include two sets of locking mechanism groups, wherein the two ends of the fourth rod 614 of one locking mechanism group are respectively connected to the two ends of the fourth rod 614 of the other locking mechanism group via a linkage 7, for example, a steel wire. The linkage 7 needs to be able to transmit at least tensile force; therefore, the linkage 7 may be made of a soft material, such as steel wire. Optionally, the linkage 7 may also transmit thrust. In such an embodiment, the linkage 7 may be a rod made of a rigid material.

[0169] The following description, in conjunction with Figures 6 to 9, illustrates the linkage process of the two sets of locking mechanisms according to an embodiment of this application. Referring to Figures 6 and 8, both the first moving member 41 and the second moving member 46 in the two sets of locking mechanisms are in the locked position, at which point the case 2 can be locked onto the base 3. When it is necessary to disassemble the case 2, the user pulls the release member 43 on the right side of the carrier 1 (as shown in Figure 8), the angle ci between the first rod 611 and the first rod 612 decreases, and the fourth rod 614 pivots in the third pivot direction R3 (shown as counterclockwise in Figure 8), causing the first moving member 41 and the second moving member 46 to move closer to each other toward the release position. During this process, the linkage member 7 near the rear of the carrier 1 in Figure 6 applies a pulling force to the fourth rod 614 located on the left side of the case, driving the fourth rod 614 to pivot in the second pivot direction R3. For the locking mechanism group located on the left side of the suitcase, under the action of the four-bar linkage, the included angle α between the first bar 611 and the second bar 612 decreases. The first bar 611 and the second bar 612 respectively drive the first moving part 41 and the second moving part 46 to move closer to each other towards the unlocking position, until the first moving part 41 and the second moving part 46 on both sides of the carrier 1 simultaneously reach the unlocking position. At this time, the suitcase 2 is unlocked from the base 3 and can be disassembled. It is understood that if the user pulls the unlocking part 43 on the left side of the carrier 1, the above unlocking process will be executed similarly. By setting the linkage 7, the user only needs to pull the unlocking part 43 on the left side of the carrier 1 to unlock all the locking mechanisms 4 in the carrier 1, which is convenient and simple to use.

[0170] Referring to Figures 23 and 24, one embodiment of this application provides a vehicle A1. Vehicle A1 includes a vehicle body A1 and a connecting mechanism A4. The vehicle body A1 includes multiple sides A14 and a bottom A12 located below the multiple sides A14, the multiple sides A14 and the bottom A12 together forming a receiving space. In this embodiment, the vehicle body A1 is configured as a suitcase. Optionally, the vehicle body A1 can also be configured in any other form or shape, for example, the vehicle body A1 can be configured as a backpack as shown in Figure 25; or as a child vehicle such as a bassinet, sleeping box, etc. For the suitcase according to this embodiment, the user can use the suitcase to carry objects or pets as needed, and this is not limited in this regard. Optionally, a fixing mechanism A3 is provided at the bottom A12 of the vehicle body All. One end of a connecting mechanism A4 is detachably connected to the fixing mechanism A3, and the other end of the connecting mechanism A4 is detachably connected to a moving device such as a vehicle seat, thereby detachably connecting the vehicle body All to the vehicle seat via the connecting mechanism A4. Optionally, an ISOFIX connector A50 is provided at the other end of the connecting mechanism A4, and the vehicle seat is provided with a connecting rod (not shown) that can engage with the ISOFIX connector A50. By engaging the ISOFIX connector A50 to the connecting rod, the connecting mechanism A4 is detachably connected to the vehicle seat. When it is not necessary to connect the vehicle body A11 to the mobile device, the connecting mechanism A4 can be detached from the fixing mechanism A3 of the vehicle body A11, thereby reducing the weight of the vehicle body A11 and making it easier for users to pick up and move the vehicle body A11. Optionally, the vehicle body A11 is provided with a hooking part A111 for attaching the connecting mechanism A4. When the connecting mechanism A4 is detached from the fixing mechanism A3, the connecting mechanism A4 can be hooked to the hooking part A111 to connect to the vehicle body A11. This reduces the overall volume of the vehicle A11, making it easier for users to pick up and move the vehicle A11, and also making it easier for users to easily pick up the connecting mechanism A4 and connect the vehicle body A11 to a mobile device such as a vehicle seat. Optionally, the hooking part A111 can be set as any suitable structure such as a hook, a ring, or a strap, as long as it can connect the connecting mechanism A4 to the vehicle body A11. The specific structure of the hooking part A111 is not limited in this document. Referring to Figure 26, optionally, the connecting mechanism A4 may be provided with an operating aid, such as a pull handle A54, which the user can operate to release the connection between the connecting mechanism A4 and the carrier A1.The operating aid is provided so that the user can perform the unlocking operation from a more convenient position. The operable connection between the operating aid and the connecting mechanism A4 will be described in more detail below.

[0171] Referring to Figures 27 to 30, in this embodiment, the bottom A12 of the vehicle body A1 includes an upper cover A121 and a lower cover A122. The upper cover A121 is connected (e.g., fixed to or detachably connected to) the bottom of the side A14, and a fixing mechanism A3 is fixed to the upper cover A121. The lower cover A122 is connected to the upper cover A121, and an installation space is formed between the lower cover A122 and the upper cover A121. Optionally, the lower cover A122 is provided with a connecting through hole A122a. The fixing mechanism A3 includes a fixing seat A31 and a connector A32 connected to each other. The fixing seat A31 is fixed to the upper cover A121. The connector A32 is disposed in the installation space and can be exposed from the connecting through hole A122a. In other words, one end of the connecting mechanism A4 can be detachably connected to the connector A32 through the connecting through hole A122a. Optionally, the connector A32 is a rod-shaped member. Optionally, the lower cover A122 is provided with an anti-slip pad A52 to increase the friction between the vehicle body A11 and the moving device supporting the vehicle body A11, making it difficult for the vehicle body A11 to slide relative to the moving device, thereby improving the stability of the connection between the vehicle body A11 and the moving device. Optionally, the vehicle body A11 also includes a reinforcing member A13. The reinforcing member A13 is fixed to the side A14 and / or bottom A12 of the vehicle body A11. The reinforcing member A13 includes a first fixing section A131 and a second fixing section A132. The first fixing section A131 is disposed in the installation space and is fixed to the fixing seat A31 of the fixing mechanism A3 by fasteners such as bolts. The second fixed section A132 is connected to the first fixed section A13L and the second fixed section A132 fixes the side A14 of the entire vehicle body A1. For example, the first fixed section A132 is fixed to the inside of the side A14 of the vehicle body A1, or the first fixed section A132 is embedded in the side A14 of the vehicle body A1.The inclusion of a reinforcing member A13 and a fixing seat A31 of the fixing mechanism A3 to the first fixing section A13L of the reinforcing member A13 increases the overall structural strength of the vehicle body A10. It also disperses the stress applied to the connector A32 to the reinforcing member A13 and other parts of the vehicle body A10 that contact the reinforcing member A13, such as the portion of the lower cover A122 that contacts the first fixing section A131, and the portion of the side A14 of the vehicle body A10 that contacts the second fixing section A132. This avoids the safety hazard of stress concentration on the connector A32 leading to damage (e.g., the connector A32 detaching from the fixing seat A31, or the connector A32 breaking), thereby causing the vehicle body A10 to unexpectedly disconnect from, for example, a vehicle seat. Furthermore, the reinforcing member A13 provides support for the vehicle body A10, which helps maintain its aesthetic shape. For example, for a vehicle body A1l made of a soft material, the second fixing section A132 can support the side A14 of the vehicle body A1l, which helps to prevent the vehicle body A1l from collapsing due to its own weight. Optionally, the second fixing section A132 is configured as a general U-shape, and the first fixing section A131 includes two extensions A132a, which are respectively connected to the ends of the two wings of the U-shape of the first fixing section A131. Optionally, the two extensions A132a are arranged parallel to each other. Referring together to Figures 31 to 33, in this embodiment, the connecting mechanism A4 includes a housing A41, a locking assembly A42, and an unlocking assembly A43. The housing A41 has a hollow structure to form an assembly space inside the housing A41. The housing A41 includes a locking portion A411 and a connecting portion A412 connected to each other. Optionally, the housing A41 is a one-piece structure, thereby realizing the connection between the locking portion A411 and the connecting portion A412. Parts of the locking assembly A42 and the unlocking assembly A43 are disposed within the locking portion A411 for detachable connection to the connector A32 of the fixing mechanism A3. The connecting portion A412 is used to mount an anchoring structure for detachable connection to a moving device such as a vehicle seat. In other words, the locking portion A411 and the connecting portion A412 can be two adjacent sections of the housing A41, with the locking portion A411 for connection to the fixing mechanism A3 and the connecting portion A412 for connection to the anchoring structure.In embodiments using ISOFIX connectors, the anchoring structure may be an ISOFIX connector plug A50. The locking assembly A42 includes a locking member A421 movably disposed within a locking portion A411. Optionally, the locking member A421 is rotatable or slidable relative to the locking portion A411. In this embodiment, the locking member A421 is rotatable relative to the locking portion A411 between a first locked position and a first unlocked position. For example, referring to Figures 31 and 32, the locking member A421 rotates counterclockwise from the first locked position to the first unlocked position, and correspondingly, rotates clockwise from the first...

[0172] The locking position is rotated to the first locking position. Optionally, the locking member A421 is configured as a locking hook. When the locking member A421 is rotated to the first locking position, the locking member A421 engages with the connecting member A32 of the fixing mechanism A3, for example, the hook of the locking hook engages with the rod-shaped connecting member A32. At this time, the connecting mechanism A4 cannot be disassembled from the fixing mechanism A3, that is, the connecting mechanism A4 cannot be disassembled from the vehicle body A3. When the locking member A421 is in the first unlocking position, the locking member A421 can be disengaged from the connecting member A32 of the fixing mechanism A3, and the connecting mechanism A4 can be disassembled from the fixing mechanism A3, that is, the connecting mechanism A4 can be disassembled from the vehicle body A3. Under the elastic force of the unlocking reset member A428, for example, a torsion spring, the locking member A421 rotates from the first locking position to the first unlocking position, which will be described in detail later.

[0173] Referring again to Figures 31 to 33, in this embodiment, the locking assembly A42 further includes a linkage A423. Linkage A423 is movable between a second locked position and a second unlocked position. For example, referring to Figures 31 and 32, linkage A423 slides to the right from the second locked position to the second unlocked position, and correspondingly, linkage A423 slides to the left from the second unlocked position to the second locked position. When locking member A421 is in the first locked position and linkage member A423 is in the second locked position, for example, by blocking member A424 simultaneously abutting against linkage member A423 and locking member A421, linkage member A423 locks locking member A421 in the first locked position, as shown in Figure 31. The structure and working principle of blocking member A424 will be described in detail later. At this time, locking member A421 engages with connecting member A32, and locking member A421 cannot disengage from connecting member A32. When locking member A421 is in the first locked position and linkage member A423 is in the second unlocked position, linkage member A423 releases the lock on locking member A421. For example, blocking member A424 no longer abuts against locking member A421, causing locking member A421 to unlock from the first locked position. At this time, the user drives one of locking member A421 and connecting member A32 to move away from the other of locking member A421 and connecting member A32. Locking member A421 can rotate from the first locked position to the first unlocked position, allowing locking member A421 to disengage from connecting member A32. That is, connecting mechanism A4 can be detached from the vehicle body A4, as shown in Figure 32. Specifically, when locking member A421 is in the first locked position and linkage member A423 is in the second unlocked position, locking member A421 unlocks from the first locking position. The user lifts the vehicle body All, driving connecting member A32 to move away from locking member A421, so that connecting member A32 no longer presses against locking member A421. Under the elastic force of the unlocking reset member A428, such as a torsion spring, locking member A421 rotates from the first locked position to the first unlocked position. During this process, locking member A421 disengages from connecting member A32, and connecting mechanism A4 is disassembled from vehicle body All.

[0174] Referring again to Figures 31 to 33, in this embodiment, the unlocking assembly A43 includes a drive member A433a. The drive member A433a is operatively connected to the linkage member A423, and movement of the drive member A433a can drive the linkage member A423 to move from the second locked position to the second unlocked position. In this embodiment, when the locking member A421 is in the first locked position and the linkage member A423 is in the second locked position, the user's operation causes the driving member A433a to rotate. The rotation of the driving member A433a drives the linkage member A423 to move from the second locked position to the first unlocked position. At this point, the linkage member A423 releases its lock on the locking member A421, and the locking member A421 is allowed to disengage from the vehicle body A1. Thus, the connecting mechanism A4 can be disassembled from the vehicle body A1. During this process, the locking member A421 rotates from the first locked position to the first unlocked position under the elastic force of the unlocking reset member A428. Optionally, the linkage A423 is provided with a drive groove A423d, and the drive member A433a passes through the drive groove A423d. Rotation of the drive member A433a causes it to push against the groove wall of the drive groove A423d, thereby driving the linkage A423 to move from the second locked position to the second unlocked position. It should be clarified that although a rotatable drive member A433a is shown in the application, this is merely exemplary. The drive member A433a can also be slidable, that is, the sliding of the drive member A433a drives the linkage A423 to move from the second locked position to the second unlocked position. This application does not impose any limitations on this.

[0175] When the vehicle body A1 according to the wooden embodiment is connected to, for example, a vehicle seat, the user can flexibly choose as needed: disconnect the connection between the connecting mechanism A4 and the fixing mechanism A3; or disconnect the connection between the connecting mechanism A4 and the vehicle seat; or disconnect the connection between the connecting mechanism A4 and the fixing mechanism A3 and reconnect the connecting mechanism A4 and the vehicle seat. This is very advantageous for certain application scenarios. For example, when the user needs to remove the vehicle body A1 from the vehicle seat, the user can simply disconnect the connection between the connecting mechanism A4 and the fixing mechanism A3, allowing the vehicle body A1 to be removed from the vehicle seat, while still maintaining the connection between the connecting mechanism A4 and the vehicle seat. This reduces the weight of the vehicle A1 that needs to be moved (no need to move the connecting mechanism A4, only the vehicle body A1 needs to be moved), and it is also convenient to reconnect the connecting mechanism A4 to the fixing mechanism A3 later to reconnect the vehicle body A1 to the vehicle seat. For example, when the user needs to connect the entire vehicle A1 to a device other than the vehicle seat, the user can disconnect the connecting mechanism A4 from the vehicle seat to move the entire vehicle A1 to another location and / or connect the vehicle A1 to other devices. For example, when the user needs to place the vehicle A1 in a relatively small space, the user can disconnect the connecting mechanism A4 from the fixing mechanism A3 and disconnect the connecting mechanism A4 from the vehicle seat, then attach the connecting mechanism A4 to the attachment part A111 on the main body of the vehicle A1. This reduces the overall volume of the vehicle A1 to meet the need to place the vehicle A1 in a relatively small space.

[0176] Referring again to Figures 31 to 33, in this embodiment, the locking assembly A42 includes a blocking member A424 as described above. The blocking member A424 is, for example, a blocking pin. A linkage member A423 is operatively connected to the blocking member A424, and movement of the linkage member A423 between a second locked position and a second unlocked position drives the blocking member A424 to move between the blocking position and the unlocked position. In other words, movement of the linkage member A423 from the first locked position to the first unlocked position drives the blocking member A424 to move from the blocking position to the unlocked position; movement of the linkage member A423 from the second unlocked position to the second locked position drives the blocking member A424 to move from the unlocked position to the blocking position. When locking member A421 is in the first locked position and linkage member A423 is in the second locked position, blocking member A424 is driven to the blocking position. Blocking member A424 simultaneously abuts against both locking member A421 and linkage member A423 to restrict rotation of locking member A421 towards the first unlocking position. Thus, locking member A421 is locked in the first locked position, preventing it from disengaging from connector A32 and connecting mechanism A4 from being detached from carrier A1. When locking member A421 is in the first locked position and linkage member A423 is in the first unlocking position, blocking member A424 is driven to the released position. Blocking member A424 no longer abuts against locking member A421, thus allowing rotation of locking member A421 towards the first unlocking position. At this time, the user can, for example, lift the vehicle body All to drive the connector A32 to move away from the locking foot A421. Under the elastic force of the release and reset member A428, such as a torsion spring, the locking member A421 rotates from the first locked position to the first released position, so that the locking member A421 is disengaged from the connector A32, and the connecting mechanism A4 is disassembled from the fixing mechanism A3 of the vehicle body All.

[0177] Referring again to Figures 31 to 33, in this embodiment, the locking assembly A42 further includes a mounting bracket A422. The mounting bracket A422 is fixed within the locking part A411. Optionally, the mounting bracket A422 is provided with a rotating hole A422d, and the locking member A421 is provided with a mounting hole A421b. By passing a rotating pin A427 through the rotating hole A422d and the mounting hole A421b, the locking member A421 is rotatably disposed in the mounting bracket A422, so that the locking member A421 can rotate relative to the mounting bracket A422 between a first locked position and a first unlocked position.

[0178] Optionally, the mounting bracket A422 is provided with a first stroke groove A422a extending along a first direction, and the blocking member A424 passes through the second stroke groove A422a and is movable along the second stroke groove A422a in the first direction AD1 between a blocking position and a release position. By providing the second stroke groove A422a, the blocking member A424 can only move relative to the mounting bracket A422 along the first direction AD1. Optionally, when the blocking member A424 moves to one end of the first stroke groove A422a, the blocking member A424 reaches the blocking position; when the blocking member A424 moves to the other end of the first stroke groove A422a, the blocking member A424 reaches the release position.

[0179] Optionally, the locking assembly A42 further includes a limiting member A425o, which may be configured as a limiting pin. The mounting bracket A422 is provided with a second travel groove A422b extending along a second direction AD2. The limiting member A425 passes through the second travel groove A422b and is movable along the second travel groove A422b in the second direction AD2. The linkage member A423 is provided with a limiting hole A423b, through which the limiting member A425 passes. The diameter of the limiting hole A423b is equal to or slightly larger than the outer diameter of the limiting member A425, thereby fixing the limiting member A425 relative to the linkage member A423 in the radial direction of the limiting hole A423b. Through the cooperation of the limiting member A425 and the second travel groove A422b, the linkage member A423 is movably positioned to support the mounting bracket A422. The limiting member A425 can only move along the second direction AD2 relative to the mounting bracket A422, and the linkage member A423 can also only move along the first direction AD2 relative to the mounting bracket A422. Optionally, the linkage member A423 is provided with a drive groove A423a, and the blocking member A424 passes through the drive groove A423a. Thus, the movement of the linkage member A423 between the first locked position and the first unlocked position allows the drive groove A423a to push against the blocking member A424, thereby driving the blocking member A424 to move between the blocking position and the released position. By providing the first stroke groove A422a, the second stroke groove A422b, and the drive groove A423a, the movement of the linkage member A423 along the second direction AD2 between the second locked position and the second unlocked position can drive the blocking member A424 along the first direction AD1 between the blocking position and the released position. In the wood embodiment, the first direction AD1 and the second direction AD2 are oriented in a specific way. However, this is only an example. Those skilled in the art can choose other suitable orientation relationships between the first direction AD1 and the second direction AD2 according to actual needs, as long as it can drive the movement of the linkage A423 and the movement of the blocking member A424.

[0180] Referring again to Figures 31 to 33, in this embodiment, the linkage A423 is provided with a receiving groove A423c. Optionally, the receiving groove A423c extends along the second direction AD2. The mounting bracket A422 is provided with a pushing portion A422c. For example, the pushing portion A422c can be configured as a pusher, which passes through the receiving groove A423c. The locking assembly A42 also includes a locking reset member A426. The locking reset member A426 is disposed in the receiving groove A423c, with one end abutting against the pushing portion A422c and the other end abutting against the end of the receiving groove A423c. The locking reset member A426 continuously applies an elastic force to the linkage A423, causing the linkage A423 to tend to move toward a first locked position. Optionally, the locking reset member A426 can be any suitable elastic element known in the art, such as a spring, torsion spring, or sheet spring.

[0181] Referring again to Figures 31 to 33, in this embodiment, the locking assembly A42 further includes a release reset member A428 as described above. One end of the release reset member A428 abuts against the mounting bracket A422, and the other end abuts against the locking member A421. The release reset member A428 continuously applies an elastic force to the locking member A421, causing the locking member A421 to tend to rotate away from the first locking position. Referring also to Figures 31 and 33, the release reset member A428 causes the locking foot member A421 shown in Figure 31 to tend to rotate counterclockwise. Optionally, the release reset member A428 can be any suitable elastic element known in the art, such as a torsion spring, spring, or spring sheet. Optionally, the locking assembly A42 further includes a stop A429, which is fixedly mounted on the mounting bracket A422. When the locking member A421 is in the first unlocked position, the locking member A421 abuts against the stop A429, thereby preventing the locking member A421 from continuing to rotate. In other words, the stop A429 defines the limit position to which the locking member A421 can rotate in a direction away from the first locking position (i.e., counterclockwise in Figure 31). Optionally, this limit position is the first unlocked position.

[0182] Referring to Figures 31 and 32, when the connecting mechanism A4 has been disassembled from the vehicle body A1, that is, when the connecting member A32 has disengaged from the locking member A421, the locking member A421 is in the first unlocked position, and the linkage member A423 is in the first unlocked position. At this time, under the elastic force applied by the locking reset member A426, the linkage member A423 tends to move towards the second locking position. For example, as shown in Figure 32, under the elastic force applied by the locking reset member A426, the linkage member A423 tends to move to the left. The movement of the linkage member A423 towards the first locking position will drive the blocking member A424 towards the blocking position, which may cause the blocking member A424 to interfere with the locking member A421 in the first unlocked position, that is, to abut against the locking member A421 in the first unlocked position. This may cause the locking member A421 to be fixed in the first unlocked position. This can be understood with reference to Figure 32. For example, if the linkage A423 shown in Figure 32 can move freely to the left toward the second locking position, the blocking member A424 is driven by the linkage A423 to move upward toward the blocking position until the blocking member A424 abuts against the lower part of the locking member A421 in the first unlocking position. At this time, the locking member A421 is fixed in the first unlocking position. This is very inconvenient for reconnecting the connecting mechanism A4 to the vehicle body All, because when the locking member A421 is fixed in the first unlocking position, the connecting member A32 cannot push the locking member A421 in the first unlocking position to rotate to the first locking position. That is, the connecting member A32 cannot directly engage with the locking member A421. The user needs to re-drive the release assembly A43 to return the linkage A423 and the blocking member A424 to the second release position and the released position respectively, so that the connecting member A32 can re-engage with the locking member A421. Ideally, simply pushing the locking member A421, which is in the first release position, with the connecting member A32 will drive the locking member A421 to rotate from the first release position to the first lock position, thereby engaging the connecting member A32 with the locking member A421. To achieve this, optionally, the locking member A421 is provided with a first retaining part A421a, and the linkage A423 is provided with a second retaining part A423e. When the connecting mechanism A4 has been disassembled from the vehicle body A1, that is, when the connecting member A32 has disengaged from the locking member A421, the locking member A421 is in the first release position, and the linkage A423 is in the second release position. At this time, the first retaining part A421a comes into contact with the second retaining part A423e.Understandably, under the elastic force applied by the locking reset member A426, the linkage member A423 tends to move towards the second locked position, and under the elastic force applied by the release reset member A428, the locking member A421 tends to move away from the first locked position. Therefore, by the first holding part A421a abutting against the second holding part A423e, the locking member A421 applies a pushing force to the linkage member A423. This pushing force counteracts the tendency of the linkage member A423 to move towards the second locked position, thus keeping the linkage member A423 in the second released position. In other words, the elastic force applied by the release reset member A428 causes the linkage member A423 to apply a pushing force to the locking member A421, but this pushing force is insufficient to overcome the tendency of the locking member A421 to move away from the first locked position; that is, it is insufficient to drive the locking member A421 to move towards the first locked position. In this way, locking member A421 is held in the first unlocked position, and linkage member A423 is held in the second unlocked position, as shown in Figure 32. When it is necessary to connect connecting mechanism A4 to vehicle body A11, simply push locking member A421 in the first unlocked position through linkage member A32 to overcome the elastic force applied by unlocking reset member A428, causing locking member A421 to rotate toward the first locked position, thereby connecting connecting mechanism A4 to vehicle body A11.

[0183] Referring to Figures 34 to 37, in this example, the release assembly A43 includes a fixing member A431, an operating member A432, and a rotating member A433. The fixing member A431 is, for example, a hollow fixing tube, which is fixedly disposed. For example, the end of the fixing tube is fixed to the locking foot A411 of the housing A41 of the connecting mechanism A4. The operating member A432 is, for example, an operating knob, which is sleeved on the outer periphery of the fixing member A431 and is rotatable about the axial direction of the fixing member A431. The rotating member A433 is, for example, a rotating tube, which is coaxially inserted inside the fixing member A431 and can rotate relative to the fixing member A431. Optionally, a drive member A433a is connected to the end of the rotating member A433. Optionally, the release assembly A43 further includes a drive seat A434, which is fixed to the end of the rotating member A433, for example, the drive seat A434 is snapped onto the end of the rotating member A433. A drive member A433a is disposed at the end of the drive seat A434 and extends from the end of the drive seat A434 in a direction away from the drive seat A434. An operating member A432 is drivably connected to the rotating member A433 such that rotation of the operating member A432 relative to the fixed member A431 can drive rotation of the rotating member A433 relative to the fixed member A431, thereby driving rotation of the drive member A433a. Optionally, the operating member A432 is provided with a connecting protrusion A432a, which passes through the tube wall of the fixing member A431 and inserts into the tube wall of the rotating member A433. Rotation of the operating member A432 causes the connecting protrusion A432a to push against the tube wall of the rotating member A433, thereby driving the rotating member A433 to rotate. Optionally, the fixing member A431 is provided with a rotational stroke groove A431a extending circumferentially along the fixing member A431, the number of rotational stroke grooves A431a corresponding to the number of connecting protrusions A432a. The rotating member A433 is provided with a mating hole A433b, through which the connecting protrusion A432a passes and inserts into the mating hole A433b. Rotation of the operating member A432 causes the connecting protrusion A432a to push against the wall of the mating hole A433b, thereby driving the rotating member A433 to rotate. When the operating member A432 rotates, the connecting protrusion A432a rotates along the rotational stroke groove A431a. In other words, the rotational stroke groove A431a provides clearance space for the rotation of the connecting protrusion A432a, allowing the connecting protrusion A432a to rotate together with the operating member A432.

[0184] Referring again to Figures 34 to 37, in this embodiment, the connecting mechanism A4 is provided with two sets of locking components A42 and two housings A41, with the two sets of locking components A42 respectively disposed in the two housings A41. The two ends of the fixing member A431 are respectively fixed to the two housings A41. Each end of the rotating member A433 is provided with a driving member A433a, which is operably connected to the linkage member A423o of the first set of locking components A42. Optionally, each end of the rotating member A433 is provided with a driving seat A434, and each driving seat A434 has a driving member A433a extending from the end of the driving seat A434 in a direction away from the driving seat A434. In this way, by rotating one operating element A432, the user can simultaneously drive the linkage A423 of both sets of locking components A42 to the second unlocking position, so as to allow the locking element A421 of both sets of locking components A42 to rotate to the first unlocking position.

[0185] Referring also to Figures 36 to 39, in this embodiment, the mounting bracket A422 is provided with a mounting hole A422e. The driving member A433a passes through the mounting hole A422e into the mounting bracket A422 to be operably connected to the driving groove A423d of the linkage member A423. The diameter of the mounting hole A422e is greater than or equal to the diameter of the virtual circle formed by the rotation path of the driving member A433a. In other words, the mounting hole A422e provides rotational space for the driving member A433a.

[0186] When the connecting mechanism A4 according to an embodiment of this application is connected to a device such as a vehicle seat, the release assembly A43, especially the operating member A432, is located between the seat back and the vehicle body A1, and close to the upper surface of the seat. Therefore, the space for the user to directly contact the operating member A432 is relatively limited. To address this, in this embodiment, an operating aid is provided operably connected to the operating member A432. The user drives the operating aid to rotate the operating member A432, thereby driving the linkage A423 to move to the second release position. By providing the operating aid, the user does not need to directly contact the operating member A432, thus allowing the user to rotate the operating member A432 from a more convenient position.

[0187] Referring to Figures 40 to 42, in the embodiments shown in Figures 40 to 42, the operating aid includes an operating part for user operation and a driving part connected between the operating part and the operating member A432. The driving part is used to drive the operating member A432 to rotate. Optionally, the operating part can be any structure suitable for user operation, such as a handle A54, a pull ring A53 (refer to Figure 44), a pull cord, etc. Optionally, the driving part can be any structure suitable for transmitting driving force (generated by the user's operation of the operating part), such as a webbing A51, a cable, etc. As shown in Figures 41 and 42, optionally, the operating member A432 is provided with a connecting hole A432b, which is used for the driving part to pass through, so that the driving part can drive the operating member A432 to rotate, thereby realizing an operable connection between the driving part (operating aid) and the operating member A432 (connecting mechanism A4). For example, in an embodiment where the driving part is a webbing A51, the webbing A51 can pass through the connecting hole A432b and wrap around the hole wall K of the connecting hole A432b, so that the webbing A51 is fixedly connected to the operating member A432. In the embodiments shown in Figures 40 to 42, the operating part is a pull handle A54. The user pulls the pull handle A54 along the first release direction AD, and the pull handle A54 drives the operating member A432 to rotate along the second release direction AR through the webbing A51, as shown in Figures 41 and 42. It should be noted that in this embodiment, the first release direction AD is set to the vertically upward direction shown in Figures 41 and 42, and the second release direction AR is set to the counterclockwise direction shown in Figures 41 and 42. However, this is only exemplary, and those skilled in the art can reasonably choose other first release directions AD and second release directions AR according to actual needs.

[0188] Referring to Figures 41 and 42, in this embodiment, the length of the drive unit is relatively short, thereby allowing the operating part, such as a pull handle A54, to be positioned near and protrude from the operating member A432 for easy user access. It should be noted that the length of the drive unit, such as a webbing A51, can be reasonably selected according to actual needs. For example, in the embodiment shown in Figure 44, the length of the drive unit is relatively long, allowing the operating part, such as a pull ring A53, to be positioned on the side of the vehicle body A1 away from the connecting mechanism A4 for easy user access. Optionally, the drive unit can have other suitable lengths, and the operating part can also be positioned in other suitable locations, such as a length that allows the operating part to be positioned at the top of the vehicle body A1. This application does not limit the length of the drive unit or the position of the operating part. Optionally, in other embodiments, the operating aid may only include the drive unit, such as the webbing A51, which the user can directly pull to drive the operating member A432 to rotate. By setting up an operating aid, the user can drive the operating component A432 to rotate from a more convenient position, thereby making it easier for the user to complete the unlocking operation.

[0189] Referring to Figures 43 and 44, in some embodiments of this application, the connecting mechanism A4 may also be provided with a protective pad A40, which, for example, is fitted onto a portion of the connecting mechanism A4. When the connecting mechanism A4 is connected to the fixing mechanism A3, the protective pad A40 may be disposed below the bottom A12 (refer to Figure 25) of the vehicle body A11 to separate the bottom A12 from the device located below the bottom A12 for supporting the vehicle body A11, thereby protecting the bottom A12 and the device located below the bottom A12 from mutual abrasion or contamination. For example, the protective pad A40 may be located between the bottom A12 of the vehicle body A11 and the surface of the vehicle seat, thereby preventing the bottom A12 from abrading the fabric or leather surface of the vehicle seat, and also preventing dirt on one of the bottom A12 and the vehicle seat from contaminating the other. In the embodiment shown in Figure 44, the webbing A51 passes between the bottom A12 of the vehicle body All and the protective pad A40, such that the other end of the webbing A51 reaches the side of the vehicle body All away from the connecting mechanism A4, so that the user can pull the webbing A51.

[0190] In related technologies, there are securing devices for attaching portable vehicles such as pet carriers, pet slings, and pet baskets to vehicle seats. However, conventional securing devices are complex in structure and usually require the use of the vehicle's seatbelts to secure the vehicle to the seat, making the installation and removal of the vehicle inconvenient.

[0191] This application provides an improved securing device for attaching a vehicle to a vehicle seat. This device can securely fasten the vehicle to the vehicle seat with a simple structure and simplifies user operation. Specifically, one aspect of this application provides a securing device for attaching a vehicle to a vehicle seat, comprising a support frame and at least one connector. The at least one connector is disposed on the support frame and configured to be detachably connected to an anchor provided on the seat. The securing device can be installed to the vehicle seat through engagement of the at least one connector with the anchor. The support frame includes at least one first rod. The first rod is configured to be detachably connected to the vehicle. When the first rod is connected to the vehicle, the vehicle can be supported by the support frame and held fixed relative to the support frame, thereby being secured to the vehicle seat via the securing device.

[0192] Figures 45 to 47 illustrate a fixing device B1 according to one embodiment of this application. As shown in Figure 45, the fixing device B1 is used to fix the carrier B2 to the seat B3 of a vehicle. The carrier B2 can be a pet carrier, pet basket, pet sling, or other device suitable for carrying a pet; it can also be a stroller, infant carrier, infant sleeping box, or other device suitable for carrying an infant; or it can be a wheelchair or other carrier. In the embodiment shown in Figure 45, the carrier B2 is exemplarily a pet carrier. The fixing device B1 is adapted to be detachably connected to an anchor (not shown) disposed on the seat B3 for installation to the seat B3. The carrier B2 is adapted to be detachably connected to the fixing device B1 for fixing to the seat B3 via the fixing device B1.

[0193] For ease of description, the terms "longitudinal direction," "lateral direction," and "vertical direction" are used in this document to describe the extensional directions of the components of the fixing device B1. These directional terms should be interpreted as follows: when the fixing device B1 is installed to the seat B3 of the vehicle, "longitudinal direction" corresponds to the front-rear direction of the vehicle, "lateral direction" corresponds to the left-right direction of the vehicle, and "vertical direction" corresponds to the direction perpendicular to the plane of the vehicle. In the accompanying drawings, arrows BX and BX- schematically indicate the "left" and "right" directions, arrows BY and BY- schematically indicate the "front" and "rear" directions, and arrow Z- schematically indicates the "up" direction. These directional or orientation terms are only used to make the description of the embodiments of this application clearer and are not intended to unduly limit the scope of protection of this application.

[0194] Referring to Figures 46 and 47, the fixing device B1 includes a support frame B11 and a connector B12. The connector B12 is disposed on the support frame B11 and configured to be detachably connected to an anchor installed on the seat B3 of the vehicle. The anchor can be, for example, an ISOFIX interface of the seat B3 of the vehicle. In this case, the connector B12 can be an ISOFIX connector suitable for detachable connection to the ISOFIX interface. In particular, the fixing device B1 includes two connectors B12, each of which can be detachably connected to two TSOFTX interfaces of the seat B3 of the vehicle, to securely install the fixing device B1 to the seat B3, thereby effectively preventing the fixing device B1 from wobbling relative to the seat B3.

[0195] The support frame B11 includes at least one first rod Bill, which is configured to be detachably connected to the carrier B2. In this embodiment, the support frame B11 includes two parallel first rod Bills, which are adapted to be detachably connected to two opposite sides B21 of the carrier B2. The two opposite sides B21 of the carrier B2 can be, for example, the front and rear sides of the carrier B2, or the left and right sides of the carrier B2. The carrier B2 can be secured to the support frame B11 by connection with the first rod Bills. It is understood that in other embodiments, only one first rod Bill may be provided, or more than one first rod Bill may be provided, as long as the carrier B2 can be secured. It is also understood that in other embodiments, at least one first rod Bill may be configured to be detachably connected to the bottom surface of the carrier B2.

[0196] The support frame B11 also includes a second member B112 and a third member B113 connected to the second member B112. The second member B112 extends in a first direction (e.g., a transverse direction), and two connecting members B12 are respectively disposed at opposite ends of the second member B112. The third member B113 extends generally in a second direction (e.g., a longitudinal direction) perpendicular to the first direction, specifically, as shown in Figure 46, it extends from the second member B112 in the direction indicated by arrow BY. That is, the extension direction of the third member B113 is generally perpendicular to the extension direction of the first member B112. It can be understood that when the member is a straight member, the extension direction of the member corresponds to the angular direction of the member.

[0197] A first member Bill is connected to a third member B113, and the extension direction of the first member Bill is generally perpendicular to the extension direction of the third member B113. Specifically, the first member Bill has opposing first and second ends. The first end of the first member Bill is connected to the second member B113, and the second end of the first member Bill is provided with a first connecting member B13. The first end of the first member Bill corresponds to its lower end, and the second end of the first member Bill corresponds to its upper end. A second connecting member B22 is provided on the side B21 of the vehicle B2. The first connecting member B13 is adapted to releasably engage with the second connecting member B22. Through the engagement of the first connecting member B13 and the first connecting member B22, the vehicle B2 can be securely mounted to the first member Bill and supported by the third member Bill. Exemplarily, the releasable engagement of the first engaging member B13 and the second engaging member B22 can be achieved by a snap-fit ​​mechanism. Specifically, the first engaging member B13 is provided with a snap-fit ​​protrusion B131, and the first engaging member B22 is provided with a snap-fit ​​recess B221. When the carrier B2 is placed on the support frame B11 from top to bottom, the snap-fit ​​protrusion B131 is adapted to insert into the snap-fit ​​recess B221 to mount the carrier B2 to the first member Bill, thereby securing the carrier B2 to the seat B3 via the fixing device B1. When it is necessary to remove the carrier B2 from the fixing device B1, the carrier B2 can be moved from bottom to top, causing the second engaging member B22 to separate from the first engaging member B13. Alternatively or additionally, an engaging protrusion may be provided on the second engaging member B22, and an engaging recess may be provided on the first engaging member B13. Alternatively or additionally, an additional retaining member may be provided to retain the engagement of the first engaging member B13 and the second engaging member B22. It is understood that any other engagement method known in the art can be used to achieve the releasable engagement of the first engaging member B13 and the first engaging member B22, which will not be elaborated here.

[0198] The third link B113 is slidably connected to the second link B112 along the extension direction of the second link B112. Thus, when the vehicle B2 is mounted to the first link Bill, the lateral position of the vehicle B2 can be adjusted by sliding the first link B113 along the second link B112, allowing the vehicle B2 to move closer to or further away from the caregiver as needed. For example, when the vehicle B2 is secured to the left rear seat of the vehicle via the foot-locking device B1, and the caregiver is seated on the right rear seat, the vehicle B2 moves to the right by sliding the third link B113 to the right along the second link B112. This reduces the distance between the vehicle B2 and the caregiver, bringing the vehicle B2 closer to the caregiver, making it easier for the caregiver to care for the contents (e.g., an animal) carried in the vehicle B2. Conversely, by sliding the third rod B113 to the left along the second rod B112, the vehicle B2 moves to the left, moving further away from the caregiver. Furthermore, by adjusting the lateral position of the vehicle B2, the caregiver's line of sight to the object inside the vehicle B2 can be adjusted, allowing for better monitoring of the object.

[0199] A first sliding member B1133 is provided at the end where the third member B113 connects to the second member B112. The first sliding member B1133 is configured to slide along the second member B112. The first sliding member B1133 can be, for example, in the form of a sleeve. The first sliding member B1133 is fitted onto the second member B112 and is slidable along the second member B112. A positioning element (not shown) can be provided between the first sliding member B1133 and the second member B112 to selectively restrict or allow the sliding of the third member B113 relative to the first member B112. The positioning element allows the first sliding member B1133 to be positioned at a predetermined position relative to the second member B112 in the lateral direction, thereby limiting the sliding of the first sliding member B1133 relative to the second member B112. This ensures that the third member B113 and the first member Bill connecting the second member B113 are held in the predetermined position relative to the second member B112 in the lateral direction. Correspondingly, the carrier B2 mounted to the first member Bill is also held in the predetermined position relative to the second member B112 in the lateral direction. The positioning element can be any suitable positioning element known in the art, and will not be described in detail here.

[0200] Optionally, the first member B112 may be provided with a guide structure (not shown), configured to guide the first sliding member #61133 to slide along the second member B112. The guide structure may be, for example, in the form of a groove or a slide rail. Through the sliding engagement of the first sliding member B1133 with the guide structure, the first sliding member B1133 can slide along the second member B112 in a predetermined direction or within a predetermined range. It is understood that the sliding engagement between the third member B113 and the second member B112 can be implemented in any other manner known in the art, and will not be elaborated upon here.

[0201] The third member B113 can be a telescopic rod. Specifically, the third member B113 includes a first segment B1131 and a second segment B1132, with the first segment B1131 slidably inserted into the second segment B1132 relative to the first segment B1132. The length of the third member B113 can be adjusted by sliding the first segment B1131 relative to the second segment B1132. The connection between the first segment B1131 and the second segment B1132 can be a sleeve connection, an embedded connection, etc., as long as it allows the first segment B1131 to be telescopic relative to the second segment B1132. In the illustrated embodiment, one end of the second segment B1132 is connected to the second member B112, and the first segment B1131 is telescopically disposed at the other end of the second segment B1132 relative to the second segment B1132. In other words, in use, the first segment B1132 serves as the fixed segment of the third member B113, and the first segment B1131 serves as the movable segment of the third member B113. Although in the illustrated embodiment the first segment B1131 is slidably inserted into the first segment B1132 relative to the second segment B1132, in other embodiments the first segment B1131 can be configured to be slidably fitted onto the second segment B1132 relative to the second segment B1132.

[0202] One of the two first-bar bills has its first end connected to the first segment B1131, and the other of the two first-bar bills has its first end connected to the second segment B1132. That is, the two first-bar bills are respectively connected to the first segment B1131 and the second segment B1132 of the third-bar bill B113. Since the extension directions of the two first-bar bills are generally perpendicular to the extension direction of the third-bar bill B113, the length of the third-bar bill B113 can be adjusted by sliding the first segment B1131 relative to the first segment B1132, while simultaneously adjusting the distance between the two first-bar bills. This allows the fixing device B1 to accommodate vehicles B2 of various sizes, especially vehicles B2 of various widths or heights. For example, for a small-sized vehicle B2, the distance between the two first members Bill can be reduced, while for a large-sized vehicle B2, the distance between the two first members Bill can be increased, so that the first connecting member B13 provided on the two first members Bill can just engage with the second connecting member B22 provided on the opposite sides of the vehicle B2.

[0203] Referring to Figures 48 and 49, by sliding the first segment B1131 relative to the second segment B1132 so that the portion of the first segment B1131 extending from the first segment B1132 has a different length, the distance between the two first segments B1131 can be adjusted. For example, compared to the usage state of the fixing device B1 shown in Figure 48, in the usage state shown in Figure 49, the second segment B1131 extends a longer portion from the first segment B1132, thus having a larger distance between the two first segments B1132. The fixing device B1 in the usage state shown in Figure 48 is suitable for fixing a small-sized (e.g., smaller in length or width) vehicle B2, while the fixing device B1 in the usage state shown in Figure 49 is suitable for fixing a large-sized (e.g., larger in length or width) vehicle B2.

[0204] A locking mechanism can be provided between the first segment B1131 and the second segment B1132 to selectively restrict or allow the sliding of the first segment B1131 relative to the second segment B1132. For example, the first segment B1131 may be provided with a plurality of first locking parts B1134 along its extension direction, and the second segment B1132 may be provided with a plurality of second locking parts B1135 along its extension direction. The fixing device B1 also includes a locking member (not shown) movable between the first segment B1131 and the second segment B1132. The locking member is adapted to selectively insert into one of a plurality of second locking portions B1135 and one of a plurality of first locking portions B1134 aligned with the second locking portion B1135, to restrict the sliding of the first segment B1131 relative to the second segment B1132, thereby defining the length of the first segment B1131 extending from the second segment B1132, and thus defining the distance between the two first members B111. Furthermore, the locking member is adapted to disengage from the first locking portions B1134 and the second locking portions B1135 to allow the sliding of the first segment B1131 relative to the second segment B1132, thereby enabling adjustment of the length of the first segment B1131 extending from the first segment B1132, and thus adjusting the distance between the two first members B111. At least one of the first locking part B1134 and the second locking part B1135 may be, for example, in the form of a locking hole or a locking groove. The locking element may be, for example, in the form of a locking pin. Alternatively, multiple locking parts may be provided only in one of the first rod segment B1131 and the first rod segment B1132, while no locking part is provided in the other of the first rod segment B1131 and the second rod segment B1132, and the locking element is movably provided in the other of the first rod segment B1131 and the second rod segment B1132. In this case, the locking element is configured to selectively insert into one of these locking parts to restrict the sliding of the first rod segment B1131 relative to the second rod segment B1132. It is understood that any other locking mechanism known in the art can be used to achieve the lockable sliding of the first rod segment B1131 relative to the first rod segment B1132, which will not be described in detail here. It is also understood that the third member B113 can be any other form of telescopic rod known in the art, as long as it can make the distance between the two first members Bill connected to the different segments of the third member B113 adjustable, which will not be elaborated here.

[0205] Referring to Figures 46 and 47, when the fixing device B1 is in use, that is, in the state of fixing the vehicle B2 to the seat B3, the two first rods Bill extend generally along a third direction perpendicular to the extension direction of the second rod B112 (e.g., the lateral direction) and the extension direction of the third rod B113 (e.g., the longitudinal direction), which is, for example, the vertical direction. That is, the two first rods Bill are generally perpendicular to the plane containing the second rod B112 and the third rod B113. In particular, the first rods Bill, the second rod B112, and the third rod B113 are set to form a generally 90-degree angle with each other. The first rods Bill, the second rod B112, and the third rod B113 extending in three directions perpendicular to each other can form a stable three-dimensional structure, thereby providing a stable support space for the vehicle B2 installed to the fixing device B1.

[0206] When the fixing device B1 is in a non-use state, the two first rods Bill can be rotated to be roughly located in the plane containing the first rod B112 and the third rod B113, so that the first rod Bill, the second rod B112, and the third rod B113 are roughly in the same plane. This reduces the space occupied by the fixing device B1 when it is not in use, thus facilitating its carrying or storage. When the two first rods Bill are roughly perpendicular to the plane containing the second rod B112 and the third rod B113, the state of the fixing device B1 can be called the unfolded state, and when the two first rods Bill are roughly located in the plane containing the second rod B112 and the third rod B113, the state of the fixing device B1 can be called the folded state.

[0207] Optionally, the third member B113 can be configured to be rotatably connected to the second member B112 about its axis. In this document, the axis of a member refers to a straight line passing through its geometric center and extending along its direction. With the two first members B111 fixedly connected to the third member B113, rotation of the third member B113 about its axis can drive the two first members B112 to rotate, thereby changing the angle of the extension direction of the two first members B112 relative to the plane containing the second and third members B112, thus enabling the fixing device B1 to switch between an extended and retracted state. A rotation locking mechanism can be provided between the second member B113 and the second member B112 to selectively allow or restrict the rotation of the third member B113 relative to the second member B112. The rotation locking mechanism can be implemented using any suitable locking mechanism known in the field, and will not be elaborated here.

[0208] Optionally, both first members Bill can be configured to be rotatably connected to the third member B113 about its axis. By rotating each first member Bill about the third member B113, the angle of the extension direction of each first member Bill relative to the plane containing the first and third members B112 can be changed, thereby switching the fixing device B1 between its extended and retracted states. A rotation locking mechanism can also be provided between each first member B112 and the third member B113 to selectively allow or restrict the rotation of the first member Bill relative to the third member B113. The rotation locking mechanism can be implemented using any suitable locking mechanism known in the field, and will not be elaborated upon here.

[0209] Figures 50 to 55 illustrate a foot-fixing device B1 according to an embodiment of this application. The main differences between the fixing device B1 in this embodiment and the fixing device B1 in the above embodiments will be described below, and the similarities will not be repeated.

[0210] Referring to Figures 50 and 52, the two first-stage bills connected to the third-stage bill B113 are both telescopic rods. Specifically, each first-stage bill includes a first segment B1111 and a second segment B1112, with the first segment B1111 slidably fitted onto the second segment B1112 relative to the second segment B1112. The length of the first-stage bill can be adjusted by sliding the first segment B1111 relative to the second segment B1112. The connection between the first segment B1111 and the second segment B1112 can be a fitted connection, an embedded connection, etc., as long as it allows the first segment B1111 to be telescopic relative to the second segment B1112. In the illustrated embodiment, one end of the second segment B1112 is connected to the third member B113, and the first segment B1111 is telescopically disposed at the other end of the second segment B1112 relative to the second segment B1112. That is, in use, the second segment B1112 serves as the fixed segment of the first member Bill, and the second segment B1111 serves as the movable segment of the first member Bill. Although in the illustrated embodiment the first segment B1111 is slidably sleeved on the second segment B1112 relative to the second segment B1112, in other embodiments the first segment B1111 can be configured to be slidably inserted into the second segment B1112 relative to the first segment B1112.

[0211] The first segment B1111 has a first end and a second end opposite to each other. The first end of the first segment B1111 is slidably connected to the second segment B1112, and the second end of the first segment B1111 is provided with a first coupling member B13. As described above, the first coupling member B13 is adapted to releasably engage with the first coupling member B22 provided on the carrier B2. Since the first segment Bill extends substantially vertically, the height of the first coupling member B1113 can also be adjusted by sliding the first segment B1111 relative to the second segment B1112, thereby allowing the fixing device B1 to accommodate carriers B2 of various sizes, especially various heights.

[0212] Referring to Figures 51 and 52, the height of the first connecting member B13 can be adjusted by sliding the first segment B1111 relative to the second segment B1112 so that the portion of the second segment B1112 extending from the first segment B1111 has a different length. For example, compared to the usage state of the fixing device B1 shown in Figure 51, in the usage state shown in Figure 52, the first segment B1112 extends a longer portion from the first segment B1111, therefore, the first connecting member B11 has a longer length, and correspondingly, the first connecting member B13 has a higher height. The fixing device B1 in the usage state shown in Figure 51 is suitable for fixing a small-sized (e.g., low-height) vehicle B2, while the fixing device B1 in the usage state shown in Figure 52 is suitable for fixing a large-sized (e.g., high-height) vehicle B2.

[0213] A locking mechanism may be provided between the first segment B1111 and the second segment B1112 to selectively restrict or allow the sliding of the first segment B1111 relative to the second segment B1112. For example, the first segment B1111 may be provided with a plurality of first locking parts B1113 along its extension direction, and the first segment B1112 may be provided with a plurality of second locking parts B1114 along its extension direction. The fixing device B1 also includes a locking element (not shown) movable between the first segment B1111 and the second segment B1112. The locking member is adapted to selectively insert into one of a plurality of first locking portions B1113 and one of a plurality of second locking portions B1114 aligned with the first locking portion B1113, to restrict the sliding of the first segment B1111 relative to the second segment B1112, thereby defining the length of the second segment B1112 extending from the first segment B1111, and thus defining the length of the first member Bill. Furthermore, the locking member is adapted to disengage from the first locking portions B1113 and B1114 to allow the sliding of the first segment B1111 relative to the second segment B1112, thereby adjusting the length of the first segment B1111 extending from the second segment B1112, and thus adjusting the length of the first member Bill. At least one of the first locking portions B1113 and B1114 may be, for example, in the form of a locking hole or a locking groove. The locking element can be, for example, in the form of a locking pin. Alternatively, multiple locking parts can be provided only in one of the first segment B1111 and the second segment B1112, while no locking part is provided in the other of the first segment B1111 and the second segment B1112, with the locking element movably disposed in the other of the first segment B1111 and the second segment B1112. In this case, the locking element is configured to selectively insert into one of these locking parts to restrict the sliding of the first segment B1111 relative to the first segment B1112. It is understood that any other locking mechanism known in the art can be used to achieve the lockable sliding of the first segment B1111 relative to the second segment B1112, which will not be elaborated here. It is also understood that the first segment Bill can be any other telescopic rod form known in the art, as long as the length of the first segment Bill is adjustable, which will not be elaborated here.

[0214] At least one of the two first rods B113 has its first end slidably connected to a third rod B113 along the extension direction of the first rod B113. The distance between the two first rods B113 can be adjusted by sliding at least one of the two first rods B113 along the third rod B113, allowing the foot-fixing device B1 to accommodate various sizes, particularly various widths or lengths of the carrier B2. Referring to Figures 50, 53, and 55, in this embodiment, the first rod B113 closer to the second rod B112 is slidably connected to the third rod B113. Hereinafter, the first rod B113 closer to the second rod B112 will be referred to as the rear-side first rod B113, and the other first rod B113 will be referred to as the front-side first rod B113. A second sliding member B1115 is provided at the end where the first rod B111 connects to the third rod B113. The second sliding member B1115 is constructed to slide along the third rod B113, and specifically, along the second segment B1132 of the third rod B113. The second sliding member B1115 can be, for example, in the form of a sliding sleeve. The second sliding member B1115 is fitted onto the second segment B1132 and is slidable along the second segment B1132. Hereinafter, the end of the second segment B1132 connected to the second rod B112 is referred to as the front end of the second segment B1132, and the end of the second segment B1132 away from the second rod B112 is referred to as the rear end of the first segment B1132.

[0215] With the angle of the third member B113 unchanged and the position of the first member Bill on the front side of the third member B113 unchanged, the position of the first member Bill on the rear side of the third member B113 can be changed by sliding the second slider B1115 between the front and rear ends of the first member segment B1132, thereby adjusting the distance between the two first members Bill. For example, as shown in FIG53, when the second slider B1115 is generally located at or adjacent to the rear end of the second member segment B1132, there is a large first distance between the two first members Bill. At this time, the fixing device B1 is suitable for fixing a large-sized (e.g., large length or width) carrier B2. As shown in FIG55, when the first slider B1115 is generally located at or adjacent to the front end of the second member segment B1132, there is a small second distance between the two first members Bill. At this point, the fixing device B1 is suitable for fixing a small-sized (e.g., small in length or width) carrier B2. As shown in FIG54, when the second sliding member B1115 is approximately located at the middle of the second rod segment B1132, there is a second distance between the two first rods Bi111, which is between the first distance and the second distance. At this point, the fixing device B1 is suitable for fixing a moderately sized (e.g., moderate in length or width) carrier B2.

[0216] A positioning element (not shown) can be provided between the second sliding member B1115 and the second rod segment B1132 to selectively restrict movement.

[0217] Alternatively, it may allow the second slider B1115 to slide relative to the first link segment B1132. The positioning element can position the second slider B1115 at a predetermined position on the second link segment B1132 to limit the sliding of the second slider B1115 relative to the second link segment B1132, so that the first link segment Bill located on the rear side remains in a predetermined position on the second link segment B1132, and correspondingly, a predetermined distance is maintained between the two first link segments Bill. The positioning element can be implemented using any suitable positioning element known in the art, and will not be described in detail here.

[0218] Optionally, the second segment B1132 may be provided with a guide structure (not shown), configured to guide the sliding of the second slider B1115 along the second segment B1132. The guide structure may be, for example, in the form of a groove or a rail. Through the sliding engagement of the second slider B1115 with the guide structure, the first slider B1115 can slide along the second segment B1132 in a predetermined direction or within a predetermined range. It is understood that the first member Bill located at the front can also be slidably connected to the second member B113 along the extension direction of the second member B113, and the sliding engagement between the first member Bill located at the rear or the first member Bill located at the front and the third member B113 can be achieved in any other manner known in the field of woodworking, and will not be elaborated here.

[0219] Figures 56 to 59 illustrate a fixing device B1 according to one embodiment of the present invention. The main differences between the fixing device B1 in this embodiment and the fixing device B1 in the above embodiments will be described below, and the similarities will not be repeated.

[0220] Referring to Figure 56, the support frame B11 further includes a fourth rod B114, which is connected to the third rod B113. Specifically, the fourth rod B114 is connected to the end of the second rod B113 furthest from the second rod B112. Although in the illustrated embodiment, the first rod B113 is a single rod with a non-adjustable length, in other embodiments, the first rod B113 may also be a telescopic rod similar to the embodiments shown in Figures 45 to 49 above, or the embodiments shown in Figures 50 to 55. The two first rods Bill of the support frame B11 are arranged in parallel. The first ends of the two first rods Bill are respectively connected to the opposite ends of the fourth rod B114, and the first ends of the two first rods Bill are respectively provided with first connecting members B13. As described above, the first connecting member B13 is adapted to releasably engage with the second connecting member B22 of the carrier B2. The extension direction of the fourth member B114 is generally parallel to the extension direction of the second member B112, and correspondingly, generally perpendicular to the extension direction of the third member B113. The extension direction of each of the two first members Bill is generally perpendicular to the extension direction of the fourth member B114. The fourth member B114 can be integrally formed with the two first members Bill to form a generally U-shaped structure. In particular, similar to the embodiments shown in Figures 50 to 55 above, the first members Bill can be telescopic rods, including a first segment B1111 and a second segment B1112. In this case, the fourth member B114 can be integrally formed with the second segment B1112 of the two first members Bill.

[0221] As shown in Figure 56, when the fixing device B1 is in use, that is, in a state for fixing the vehicle B2 to the seat B3, the two first rods Bill extend generally along a third direction perpendicular to the extension direction of the second rod B112 (e.g., the lateral direction) and the extension direction of the third rod B113 (e.g., the longitudinal direction), which is, for example, the vertical direction. That is, the two first rods Bill are generally perpendicular to the plane containing the second rod B112 and the first rod B113. In particular, the first rods Bill, the second rod B112, and the third rod B113 are set to form a generally 90-degree angle with each other. The first rods Bill, the second rod B112, and the third rod B113 extending in three directions perpendicular to each other can form a stable three-dimensional structure, thereby providing a stable support space for the vehicle B2 installed to the fixing device B1.

[0222] The first member B112, the third member B113, and the fourth member B114 can be substantially located in the same plane. Optionally, the fourth member B114 can be configured to be rotatably connected to the third member about an axis. By rotating the fourth member B114 about its axis, the two first members Bill can be rotated, thereby changing the angle of the extension direction of the two first members Bill relative to the plane containing the second member B112, the second member B113, and the fourth member B114, so as to achieve the switching of the fixing device B1 between the extended state and the retracted state. In the retracted state, the two first members Bill can be rotated to be substantially located in the plane containing the second member B112, the third member B113, and the fourth member B114, so that the first member Bill, the second member B112, the third member B113, and the fourth member B114 are substantially in the same plane. This reduces the space occupied by the fixing device B1 when it is not in use, thus facilitating its carrying or storage. A rotation locking mechanism can be provided between the fourth member B114 and the third member B113 to selectively allow or restrict the rotation of the fourth member B114 relative to the third member B113. The rotation locking mechanism can be implemented using any suitable locking mechanism known in the art, and will not be described in detail here.

[0223] Referring to Figures 56, 57 to 59, similar to the embodiments shown in Figures 45 to 49 above, the first sliding member B1133 is provided at the end where the first member B113 connects to the second member B112. The first sliding member B1133 is configured to slide along the second member B112. The first sliding member B1133 can be, for example, in the form of a sliding sleeve. The first sliding member B1133 is sleeved on the second member B112 and slides along the second member B112. Therefore, when the vehicle B2 is installed on the first rod B111, the position of the vehicle B2 in the lateral direction can be adjusted by sliding the second rod B113 along the second rod B112, allowing the vehicle B2 to move closer to or further away from the caregiver as needed. For example, when the vehicle B2 is fixed to the left rear seat of the vehicle by the fixing device B1, and the caregiver is sitting on the right rear seat, the vehicle B2 moves to the right by sliding the third rod B113 along the second rod B112 toward the right (for example, the third rod B113 moves from the position shown in Figure 57 to the position shown in Figure 58 on the first rod B112). This reduces the distance between the vehicle B2 and the caregiver, bringing the vehicle B2 closer to the caregiver and making it easier for the caregiver to care for the object (e.g., an animal) carried in the vehicle B2. Conversely, by sliding the second rod B113 along the second rod B112 toward the left... (For example, the second link B113 moves from the position shown in Figure 57 to the position shown in Figure 59, between the second link B112 and the position shown in Figure 57), and the carrier B2 moves to the left, moving further away from the caregiver. Furthermore, by adjusting the lateral position of the carrier B2, the caregiver's line of sight to the object carried in the carrier B2 can be adjusted, allowing for better monitoring of the object.

[0224] A positioning element (not shown) can be provided between the first sliding member B1133 and the first rod B112 to selectively restrict or allow the sliding of the third rod B113 relative to the second rod B112. The positioning element allows the first sliding member B1133 to be positioned in a predetermined position relative to the second rod B112 in the lateral direction, thus restricting the sliding of the first sliding member B1133 relative to the second rod B112. This ensures that the second rod B113 and the first rod Bill connected to the second rod B113 are held in a predetermined position relative to the second rod B112 in the lateral direction. Correspondingly, the carrier B2 mounted to the first rod Bill is also held in a predetermined position relative to the second rod B112 in the lateral direction. The positioning element can be any suitable positioning element known in the field of woodworking, and will not be described further here.

[0225] Optionally, the first member B112 may be provided with a guide structure (not shown), configured to guide the sliding of the first slider B1133 along the second member B112. The guide structure may be, for example, in the form of a groove or a slide rail. Through the sliding engagement of the first slider B1133 with the guide structure, the first slider B1133 can slide along the second member B112 in a predetermined direction or within a predetermined range. It is understood that the sliding engagement between the third member B113 and the second member B112 can be implemented in any other manner known in the art, and will not be elaborated upon here.

[0226] Figures 60 to 63 illustrate a fixing device B1 according to one embodiment of the wood application. The main differences between the foot fixing device B1 in this wood embodiment and the foot fixing device B1 in the above embodiments will be described below, and the similarities will not be repeated.

[0227] As shown in Figure 60, the support frame B11 includes two parallel first rods Bill and two parallel third rods B113o. Both third rods B113 are slidably connected to the second rod B112 along its extension direction and are also connected to the two first rods Bill. Specifically, the first ends of the two third rods B113 are slidably connected to the second rod B112 along its extension direction, and the second ends of the two third rods B113 are respectively connected to the first end of a corresponding first rod Bill. The second ends of the two first rods Bill are each provided with a first connecting member B13o. As described above, the first connecting member B13 is adapted to releasably engage with a second connecting member B22 provided on the carrier B2. Although in the illustrated embodiment, the third member B113 is a single member with a non-adjustable length, in other embodiments, the third member B113 may also be a telescopic rod similar to the embodiments shown in Figures 45 to 49 and Figures 50 to 55 above.

[0228] The extension directions of the two third members B113 are generally perpendicular to the extension direction of the second member B112. The extension directions of the two first members Bill are also generally perpendicular to the extension directions of the two third members B113. Each third member B113 is integrally formed with the first member Bill to which it is connected, forming a generally L-shaped structure. In particular, similar to the embodiments shown in Figures 50 to 55 above, the first member Bill can be a telescopic rod, including a first segment Bill and a second segment B1112. In this case, each third member B113 can be integrally formed with the second segment B1112 of the first member Bill to which it is connected.

[0229] Referring to Figures 60, 61 to 63, similar to the embodiments shown in Figures 45 to 49 above, each third member B113 has a first sliding member B1133 at one end connected to the second member B112. The first sliding member B1133 is configured to slide along the second member B112. The first sliding member B1133 can be, for example, in the form of a sliding sleeve. The first sliding member B1133 is fitted onto the second member B112 and slides along the second member B112. Through their respective first sliding members B1133, both third members B113 can slide independently along the second member B112. In this way, not only can the distance between the two first rods Bill be adjusted, allowing the fixing device B1 to accommodate various sizes of vehicles B2, especially vehicles B2 with various widths or angles, but also the position of the vehicle B2 in the lateral direction can be adjusted when the vehicle B2 is installed on the two first rods Bill 11. For example, referring to Figures 61 and 62, with the position of the right-side first rod B113 on the second rod B112 remaining unchanged, the left-side third rod B113 is slid to the left along the second rod B112 (the left-side third rod B113 moves from the position shown in Figure 61 to the position shown in Figure 62 on the second rod B112), increasing the distance between the two third rods Bill. As a result, the distance between the two first rods Bill increases, and compared to the usage state shown in Figure 61, in the usage state shown in Figure 62, the fixing device B1 can fix a larger size (e.g., larger angle or width) vehicle B2. Referring to Figures 62 and 63, with the third link B113 on the left side remaining in the same position on the second link B112, the second link B113 on the right side slides to the right along the second link B112 (the third link B113 on the right side moves from the position shown in Figure 62 to the position shown in Figure 63 on the second link B112), further increasing the distance between the two second links B113. As a result, the distance between the two first links B111 is further increased, and compared to the usage state shown in Figure 62, in the usage state shown in Figure 63, the fixing device B1 can fix a larger (e.g., longer or wider) vehicle B2.

[0230] Furthermore, when the carrier B2 is installed on the two second rods (Bill), the position of the carrier B2 in the lateral direction can be adjusted by simultaneously sliding the two third rods B113 to the left or right along the second rod B112, allowing the carrier B2 to move closer to or further away from the caregiver as needed. The sliding engagement between the two second rods B113 and the second rod B112 can be referred to the sliding engagement between a single second rod B113 and the second rod B112 described in the above embodiments, and will not be repeated here.

[0231] Figures 64 and 65 illustrate a fixing device B1 according to one embodiment of the wood application. The main differences between the fixing device B1 in this embodiment and the fixing device B1 in the above embodiments will be described below; similarities will not be repeated.

[0232] Referring to Figures 64 and 65, the support frame B11 of the fixing device B1 includes two parallel first rods Bill, each of which has a generally L-shaped structure. Two connectors B12 are respectively disposed at the lower end or upper part of the two first rods Bill, and the upper end or upper part of the two first rods Bill is adapted to be detachably connected to the side B21 of the fixture B2. As described above, the connectors B12 can be detachably connected to the anchors of the seat provided in the vehicle. Although in the illustrated embodiment, the support frame B11 includes two first rods Bill, in other embodiments, the support frame B11 may include more than one first rod Bill. The first rod Bill includes a first rod portion Bl1a and a second rod portion Bl11b, the extension direction of the first rod portion Bl1a being generally perpendicular to the extension direction of the second rod portion Bl11b. Exemplarily, the first member Bill11a extends along a first direction (e.g., vertical), and the second member Bill11a extends generally along a second direction (e.g., longitudinal) perpendicular to the first direction. The first member Bill11a and the second member Bill11b can be integrally formed. Specifically, the junction of the first member Bill11a and the second member Bill11b, i.e., the bend in the L-shaped structure of the first member Bill, is generally arc-shaped, making the transition between the first member Bill11a and the second member Bill11b smoother, avoiding sharp corners, and thus reducing abrupt changes and concentrations of stress in localized areas.

[0233] The support frame B11 also includes a reinforcing member B115, which is connected between the two first member bills. Although in the illustrated embodiment, the support frame B11 includes only one reinforcing member B115, in other embodiments, the support frame B11 may include two or more reinforcing members B115. The reinforcing member B115 extends generally perpendicular to the extension direction of the first member bill 111a, and also extends in a third direction (e.g., a lateral direction) perpendicular to the extension direction of the first member bill 111a. By providing the reinforcing member B115, in the event of an impact, the reinforcing member B115 can transfer the impact force from the more stressed first member bill to the other first member bill, thereby reducing the risk of bending, loosening, or swaying of the support frame B11.

[0234] Referring again to Figures 64 and 65, the side surface B21 of the carrier B2 is provided with two fasteners B23. The upper ends or upper parts of the two first rods Bill are adapted to be inserted into the two fasteners B23 respectively and are detachably connected to the side surface B21 of the carrier B2. Exemplarily, each fastener B23 forms a through hole extending vertically on the side surface B21 of the carrier B2. When the carrier B2 is installed to the fixing device B1 from top to bottom, the upper end of the first rod portion Bl11a of each first rod Bill is inserted into the through hole formed by the corresponding fastener B23 and passes through the through hole. The carrier B2 can be installed to the fixing device B1 by the insertion and engagement of the first rod portion Bl11a with the fastener B23. When the carrier B2 is installed to the fixing device B1, the first rod portion Bl11a can substantially conform to the side surface of the carrier B2. It is understood that the fastener B23 may also be provided with a blind hole, rather than a through hole, suitable for insertion and mating with the upper end of the first rod Bllla, as long as it can secure the carrier B2 to the first rod Bllla. It is also understood that any other engagement method known in the art can be used to achieve a detachable connection between the first rod Bllla and the fastener B23, which will not be elaborated here.

[0235] Figures 66 and 67 illustrate the fixing device B1 according to the first embodiment of this application. The main differences between the fixing device B1 in this embodiment and the fixing device B1 in the embodiments shown in Figures 64 and 65 above will be described below, and the similarities will not be repeated.

[0236] Similar to the embodiments shown in Figures 64 and 65 above, the side B21 of the carrier B2 is provided with a fixing member B23. The difference is that the upper ends or upper parts of the two first rods Bill are adapted to be inserted into the same fixing member B23. In particular, when the carrier B2 is installed onto the fixing device B1 from top to bottom, the upper ends of the first rod portions B11a of the two first rods Bill are adapted to be inserted into the through holes formed by the fixing member B23 and protrude from the through holes. Compared to providing multiple fixing members B23 that cooperate with multiple first rods B111 respectively, providing only one fixing member B23 that cooperates with multiple first rods Bill simultaneously allows the user to more easily and quickly fix the carrier B2 to the first rods Bill.

[0237] The fastener B23 can be made of a rigid material or a flexible material. For example, the fastener B23 can be made of a rigid metal sheet, with the width of the through hole formed on the side B21 of the carrier B2 matching the thickness of the upper end of the first rod Billa, and the length of the through hole matching the distance between the opposite sides of the two first rod Billa, allowing the two first rods Billa to be inserted into the through hole at the same size. Alternatively, the fastener B23 can be made of a single-stranded band, with a through hole formed between the inner side of the fastener B23 and the side B21 of the carrier B2, allowing the upper ends of the two first rods Billa to pass through. When the upper parts of the two first rods Billa pass through the through hole between the inner side of the fastener B23 and the side B21 of the carrier B2, the elastic contraction force of the fastener B23 keeps the carrier B2 fixed relative to the two first rods Billa.
