[0038] The present utility model is described in more detail below in connection with the figures and embodiments.

[0039] Orientation terms such as up, down, left, right, front, back, front, back, up, down, etc., referred to or may be referred to in this description, are defined with respect to the configuration illustrated in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a particular component, respectively. These are relative concepts that may change depending on the location and state of use in which they are employed. Therefore, these and other orientation terms should not be interpreted as restrictive terms.

[0040] With reference to [Fig. 1] to [Fig. 5], the present embodiment illustrates a quick-release luggage rack device and a bicycle luggage rack, both of which can be assembled or, alternatively, supplied independently (and can be assembled separately with other suitable device structures). With reference to [Fig. 7], when the quick-release luggage rack device 1 is assembled onto the bicycle luggage rack 2, they form a functional assembly component. In the case of the bicycle luggage rack, the installation position on the bicycle, for example, the mounting position, can vary according to the actual application requirements. The installation position of the bicycle luggage rack is defined according to the actual application requirements.For example, a bicycle rack can be used as either the front or rear rack of the bicycle.

[0041] Referring to [Fig. 2], 3 and 4, the quick-release luggage rack device in this embodiment comprises a base 11, a fixed mounting seat 12 and a movable mounting seat 13, and at least one compressible elastic element 14. In this embodiment, the base 11 is supported on the bicycle luggage rack during assembly, and the fixed mounting seat 12 and the movable mounting seat 13 are arranged in a fixed and movable manner on a lower portion of the base. 11, respectively, and each of the fixed assembly seat 12 and the movable assembly seat 13 is provided with a locking tab formed by a projection. The luggage rack of a bicycle comprises two assembly bars 21 spaced apart, in which two sides of the two assembly bars 21 facing the same side or opposite sides are each provided with a locking groove 2a, and the two assembly bars 21 correspond respectively to the fixed assembly seat 12 and the movable assembly seat 13.The base 11 of the quick-release luggage rack device is supported on the bicycle rack. The corresponding locking tab la of each of the fixed mounting bracket 12 and the movable mounting bracket 13 engages in the locking groove 2a of the two mounting bars 21 in the same horizontal direction or in opposite horizontal directions, respectively, to allow the quick-release luggage rack device to be assembled onto the bicycle rack. The locking tab la is horizontally snapped into the locking grooves 2a on the mounting bars 21 to form a rigid lock to prevent separation in the vertical direction. The retaining effect of the walls of the locking grooves 2a on the locking tab la improves the performance of the assembly by resisting loosening that occurs under load or vibration.Overall, the locking tab 1a and the locking groove 2a fit together without sacrificing the convenience of disassembly and assembly, greatly enhancing the anti-displacement stability of the assembly, thus preventing loosening.

[0042] Thus, for the quick-release luggage rack device, the fixed assembly seat 12 and the movable assembly seat 13 are designed such that the corresponding locking tab 1a of each provides a gripping state in the same horizontal direction or in opposite horizontal directions, respectively, in order to obtain an assembled state of the quick-release luggage rack device. For the bicycle luggage rack, the two assembly bars 21 are designed such that the corresponding locking grooves 2a of each provide a gripping state in the same horizontal direction or in opposite horizontal directions, respectively, in order to obtain an assembled state of the bicycle luggage rack.

[0043] When assembling the quick-release luggage rack device onto a bicycle rack, the user can pre-compress the elastic element 14 to keep the movable assembly seat 13 retracted, then engage the fixed assembly seat 12 horizontally onto the corresponding part of the bicycle rack, and then use the elasticity of the elastic element 14 to release the movable assembly seat 13 to automatically complete the The engagement process is simple, and the two parts are spaced apart in the direction of engagement to ensure the stability of the locking state. The disassembly process is more convenient; a simple compression of the elastic element 14 causes the movable assembly seat 13 to release the buckle, thus enabling the quick separation of the assembly and the bicycle rack. The quick-release rack disassembly device of this embodiment greatly simplifies the assembly and disassembly steps and is easy to use. The components are not easily loosened during normal use because the movable assembly seat 13 and the fixed assembly seat 12 are independently spaced. Overall, this embodiment effectively solves the problem of the cumbersome disassembly of the prior art.

[0044] In this embodiment, a space is provided between the locking tab la of the fixed assembly seat 12 and the movable assembly seat 13 and the base 11, and the locking tab la is structurally a structure formed by one end of the fixed assembly seat 12 / movable assembly seat 13 protruding in the gripping direction, such that an auxiliary slot 1b is formed in the space between the locking tab la of the fixed assembly seat 12 and the movable assembly seat 13 and the base 11; the two assembly bars 21 have a spacing at their upper faces and the upper edges of the respective locking grooves 2a, a part (namely the part corresponding to the auxiliary slot 1b) forms an auxiliary insertion rod 2b, the auxiliary insertion rod 2b and the auxiliary slot 1b are in an insertion relationship,so that the locking tab engages in the locking grooves 2a at the same time as the auxiliary slot 2b is inserted synchronously into the auxiliary slot 1b. The locking tab engages with the locking groove 2a to provide a basic vertical constraint to prevent disengagement of the assembly, while the auxiliary insertion rod 2b is inserted into the auxiliary slot 1b to form a complementary constraint, creating a double lock in addition to the original horizontal engagement of the locking tab and the locking groove 2a, thus making the assembly stronger and more stable.

[0045] Thus, for the quick-release luggage rack device, the fixed mounting seat 12 and the movable mounting seat 13 are further designed so that, when the corresponding locking tab of each of them provides the engaged state in the same horizontal direction or in the opposite horizontal direction, the corresponding auxiliary slot 1b of each of them provides an inserted state in the same horizontal direction or in the opposite horizontal direction, respectively and in a synchronized manner. For the bicycle luggage rack, the two assembly bars 21 are designed so that, when the locking groove 2a corresponding of each of these provides respectively the gripping state in the same horizontal direction or in the opposite horizontal direction, the corresponding auxiliary insertion rod 2b of each of these provides an inserted state in the same horizontal direction or in the opposite horizontal direction, respectively and in a synchronized manner.

[0046] In certain embodiments, in connection with [Fig.2] and 4, the fixed assembly seat 12 and the assembly bar 21 have, on the basis of the grip of the locking tongue la and the locking groove 2a, and the insertion of the auxiliary insertion rod 2b and the auxiliary slot 1b, the auxiliary insertion rod 2b corresponding to the assembly bar 21 of the fixed assembly seat 12 has a positioning groove 2c on its lateral side, the positioning groove 2c being formed by embedding in the gripping direction and the width of the positioning groove 2c being progressively narrowed in the horizontal direction from the opening of the groove to the lower part of the groove.The movable assembly seat 13 is provided with a positioning structure le in the auxiliary slot 1b which can be inserted into the positioning groove 2c, the positioning structure le having a width in the horizontal direction such that the positioning groove 2c is inserted synchronously when the locking tab la of the fixed assembly seat 12 is snapped into the corresponding locking groove 2a, and that the two sides in the horizontal direction of the width of the positioning structure le are abutted against the positioning groove 2c.The reduction in the width of the positioning groove 2c is adjusted so that the positioning structure le of the movable assembly seat 13 is inserted synchronously into the positioning groove 2c during the process of engaging the locking tab la of the fixed assembly seat 12 in the locking groove 2a. The insertion phase continuously guides the transverse movement, automatically correcting the small positional deviation of the base 11 relative to the bicycle rack until the relative position of the base 11 and the bicycle rack is precisely locked at the end of the engagement. This method allows the locking seat 15 of the base 11 and the corresponding part of the bicycle rack to achieve zero-deviation contact, so that the overall structure reaches a solid state without gaps after assembly.

[0047] Thus, for the quick-release luggage rack device, the fixed assembly seat 12 is further designed so that, when the auxiliary slot 1b corresponding to that which provides the inserted state, the positioning structure provides it with an insertion state in the horizontal direction in a synchronized manner, and two sides thereof in the horizontal width direction are abutted in order to achieve the positioning of the quick-release luggage rack device. For the bicycle luggage rack, the assembly bar of the fixed assembly seat 12 is further designed so that, when its corresponding auxiliary insertion rod 1b provides the insertion state, the positioning groove 2c synchronously provides the inserted state in the horizontal direction, and thanks to the reduction in width, the positioning groove 2c is thus adapted to allow horizontal positioning by means of the stop of two corresponding groove walls.

[0048] In the embodiment, the positioning structure le is formed by at least two reinforcing bars extending from the bottom of the base 11 to the top of the locking tongue la, which, in addition to helping with snap-fit ​​positioning, is at the same time able to improve the structural resistance between the base 11 and the locking tongue la.

[0049] In the embodiment, in conjunction with [Fig. 1] and 4, several locking seats 15 are arranged on the lower part of the base 11 at or near its edges, the locking seats 15 being presented as a structure projecting downwards from the lower surface of the base 11, and the luggage rack of a bicycle further comprises two assembly bars 21 spaced apart from each other, and two side bars 22, and four edge structures are formed at the point of intersection of the side bars 22 and the assembly bars 21. The locking seat 15 of the base 11 corresponds to the corner structures, and when the quick-release luggage rack device is in the assembled state, the locking seat 15 is embedded in the corner structures and is offset from the side bars 22 and the assembly bars 21, respectively.This multidirectional constraint effectively limits the tendency of the base 11 to move in the horizontal plane, with the fixed assembly seat 12, the mobile assembly seat 13 and the corresponding part of the luggage rack of a bicycle, forming a synergistic system, making the quick-release device of the luggage rack of the embodiment less easy to loosen or move when loaded or subjected to vibrations, and improving the stability of the overall assembly state.

[0050] Thus, for the luggage rack quick-release device, the luggage rack quick-release device is designed such that, when the luggage rack quick-release device is in the assembled state, the locking seats 15 provide a stop state in at least two different horizontal directions, respectively. For the bicycle luggage rack, when the bicycle luggage rack is in the assembled state, the connection of the side bar 22 and the assembly bars 21 ensures a stop state in two different horizontal directions.

[0051] In the embodiment, in conjunction with [Fig. 3] and 4, the locking tab la of the movable assembly seat 13 has a contact surface f that can come into contact with the assembly bar 21, and the contact surface f is gradually and smoothly raised in the direction of the grip. During assembly, the locking tab la of the fixed assembly seat 12 is first snapped into the locking groove 2a of the corresponding assembly bar 21, and then the locking tab la of the movable assembly seat 13 is pressed against the corresponding assembly bar 21.At this point, the base 11 is pressed downwards, and the contact surface f slides smoothly along the assembly bar 21, causing the movable assembly seat 13 to move on the base 11 and continuously compress the elastic element 14 until the locking tab la is detached from the contact point of the assembly bar 21. At this point, the elastic element 14 instantly releases its elastic force and precisely pushes the locking tab la to be secured in the locking groove 2a. The process does not require manual pre-compression of the elastic element 14 or any additional adjustment actions. The unidirectional downward pressure can be synchronized to complete the lifting of the locking tab la and the automatic fastening step, effectively simplifying the operating process and preventing misalignment of the assembly, while maintaining the initial simplicity of disassembly.

[0052] In the embodiment, the two locking grooves 2a in the sides and the lower part of the corresponding assembly bar 21 are formed with openings, the side of the opening corresponds to the loop of the locking tongue la in the lower part of the opening, which makes it possible to effectively avoid the first loop in the fixed assembly seat 12 when the entire base assembly tilted, which results in the locking tongue la being blocked in the locking grooves 2a in the event of the occurrence of the situation.

[0053] In the embodiment, the lower surface of the movable assembly seat 13 has a groove 132, which facilitates user access to the groove 132 to pull the movable assembly seat 13 during disassembly.

[0054] In the present embodiment, as shown in [Fig. 1], 3 and 5, the lower part of the base 11, corresponding to the movable assembly seat 13, is provided with a housing groove 111, a part of the movable assembly seat 13 (namely the upper part) is connected in a sliding manner in the housing groove 111, the elastic element 14 is disposed in the housing groove 111 and two ends of it respectively support a wall of the housing groove 111 and the part of the movable assembly seat 13 in the housing groove 111.

[0055] In the embodiment, the housing groove 111 has two slides 112 on either side and extends in the direction of the grip, and the upper sides of the seat mobile assembly seat 13 includes slides 133 suspended from corresponding slides 112 and cooperating in a sliding manner with them, respectively, in order to achieve the movement of the mobile assembly seat 13 on the base 11.

[0056] In the embodiment, the end of the base 11 is provided with a removable cover 124, and the cover 124 is a component forming a complete housing groove 111, so that the cover 124 can be assembled after the movable assembly seat 13 and the elastic element 14 have been assembled in the housing groove 111.

[0057] In some embodiments, the elastic element 14 is unique, and in other embodiments, the elastic element 14 is provided in the form of two or two more and are placed next to each other.

[0058] In the embodiment, the lower surface of the base 11 is fixed using a soft rubber pad, so that the base 11 can absorb shocks and fix itself when supported by the luggage rack of a bicycle, and the number of soft rubber pads as well as the adjustment position are defined according to the actual application requirements.

[0059] For the functional assembly component in the embodiment, as shown in Figures 6 and 7, the base 11 is assembled with a functional component 3, wherein the functional component 3 has at least one optional type, and the optional type includes a storage type. The functional component is designed according to the actual usage requirements; for example, it may be designed as a support type, such as a chair seat, a child safety seat, a pizza holder, a shoulder bag, etc.

[0060] The present embodiment proposes a bicycle comprising the functional assembly component.
