[0038] Throughout these figures, the same reference numerals denote the same or equivalent parts of the present invention. Detailed Implementation
[0039] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.
[0040] To facilitate the explanation of the positional relationships between the various components, this paper introduces a first direction, a second direction, and a third direction. The first sidewall 102 and the second sidewall 103 of the receiving cavity 101 are positioned opposite each other in the first direction, and the female buckle 100 and the male buckle 200 are joined along the second direction. The first direction is the width direction of the female buckle 100 and the male buckle 200, the second direction is the thickness direction of the female buckle 100 and the male buckle 200, and the third direction is the length direction of the female buckle 100 and the male buckle 200. The third direction is perpendicular to the first and second directions. To more clearly illustrate the positional relationships of the various structures, a three-dimensional Cartesian coordinate system is added to the accompanying drawings, with the first direction being the x-axis, the second direction being the y-axis, and the third direction being the z-axis.
[0041] The following is combined with Figures 1 to 6 The locking device according to the embodiment of this utility model will be described.
[0042] like Figure 1 and Figure 3D As shown, the locking device of this utility model embodiment includes: a female buckle 100 and a male buckle 200.
[0043] The female buckle 100 has a receiving cavity 101. The first sidewall 102 and the second sidewall 103 of the receiving cavity 101 are arranged opposite each other in a first direction (i.e., the x-axis direction). The first sidewall 102 of the receiving cavity 101 has a guide surface 104, and the second sidewall 103 of the receiving cavity 101 has a first limiting part 105. The female buckle 100 is equipped with a first magnet 300, which is disposed on the bottom wall 106 of the receiving cavity 101 or at a position close to the bottom wall 106 of the receiving cavity 101.
[0044] The male buckle 200 has an insertion portion 201 corresponding to the receiving cavity 101. One side of the insertion portion 201 has a second limiting portion 202 corresponding to the first limiting portion 105. The insertion portion 201 also has a second magnet 400 corresponding to the first magnet 300. The female buckle 100 and the male buckle 200 are engaged along the second direction (i.e., the y-axis direction).
[0045] The insertion part 201 can slide along the guide surface 104 to be inserted into the receiving cavity 101.
[0046] After insertion into the receiving cavity 101, the first limiting part 105 and the second limiting part 202 lock each other, and the first magnet 300 and the second magnet 400 align and attract each other in the second direction (i.e., the y-axis direction).
[0047] The first limiting part 105 and the second limiting part 202 are rigid structures, meaning they are not easily deformed elastically.
[0048] The present invention has the following beneficial effects:
[0049] (1) The first magnet 300 and the second magnet 400 generate a magnetic force that attracts each other in the second direction, so as to lock the male buckle 200 and the female buckle 100 in the second direction. In addition, the magnetic force can also restrict the relative movement of the male buckle 200 and the female buckle 100 in the first direction.
[0050] (2) The first limiting part 105 and the second limiting part 202 of the rigid structure can be locked to each other in the second direction to further lock the male buckle 200 and the female buckle 100 in the second direction, thereby improving the connection effect.
[0051] (3) The guide surface 104 can guide the insertion part 201 to be inserted into the receiving cavity 101, and the magnetic force can help the insertion part 201 to be inserted into the receiving cavity 101.
[0052] In one implementation scheme, such as Figure 2 As shown, the female buckle 100 includes: a female buckle base plate 180 and a female buckle cover plate 190.
[0053] like Figure 2 and Figure 3AAs shown, the female mounting base plate 180 has the aforementioned receiving cavity 101 and a first mounting groove 107 facing away from the receiving cavity 101, and the first magnet 300 is installed in the first mounting groove 107.
[0054] The female buckle cover 190 is installed on the side of the female buckle base plate 180 facing away from the receiving cavity 101 to cover the first mounting groove 107 and prevent dust and other impurities from entering the first mounting groove 107. Furthermore, the female buckle cover 190 and the female buckle base plate 180 are also used for the fixed installation of the female buckle 100, facilitating the connection of the female buckle 100 to the object being mounted. For example, the female buckle base plate 180 is located at the bottom of a bicycle bag, and the female buckle cover 190 is located inside the bicycle bag and connected to the female buckle base plate 180, thus allowing the female buckle 100 to be installed on the bicycle bag.
[0055] In one implementation scheme, such as Figure 2 As shown, the first limiting part 105 extends inward from the bottom wall 106 of the second side wall 103 of the receiving cavity 101 away from the receiving cavity 101 to form a first slot 108.
[0056] The male buckle 200 further includes a male buckle substrate 280, an insertion portion 201 located on the male buckle substrate 280, and a second limiting portion 202 extending outward from a position away from the male buckle substrate 280 on the side wall of the insertion portion 201 to form a second slot 203.
[0057] Wherein, after the insertion part 201 is inserted into the receiving cavity 101, the second limiting part 202 is located in the first slot 108, and the first limiting part 105 is located in the second slot 203, so that the first limiting part 105 and the second limiting part 202 are locked to each other.
[0058] In one implementation scheme, such as Figure 2 and Figure 3D As shown, the male buckle 200 has a second mounting groove 204, which penetrates the male buckle base plate 280 and extends into the interior of the insertion portion 201. The second magnet 400 is installed in the second mounting groove 204.
[0059] The male snap fastener 200 further includes a male snap fastener cover plate 290, which is mounted to the side of the male snap fastener base plate 280 opposite to the insertion portion 201 to cover the second mounting groove 204 and prevent dust and other impurities from entering the second mounting groove 204. Similarly, the male snap fastener base plate 280 and the male snap fastener cover plate 290 are also used for fixed installation, which can facilitate the installation of the male snap fastener 200 at the place of use. For example, the male snap fastener base plate 280 and the male snap fastener cover plate 290 are respectively clamped on different sides of the installation place. After the male snap fastener base plate 280 and the male snap fastener cover plate 290 are fixedly connected, the male snap fastener 200 can be installed at the place of use.
[0060] exist Figure 2In one implementation scheme, the second magnet 400 does not penetrate the bottom wall of the second mounting groove 204, and the first magnet 300 does not penetrate the bottom wall 106 of the receiving cavity 101. That is, the second magnet 400 and the first magnet 300 are not in direct contact when aligned. Alternatively, the second magnet 400 can be configured to penetrate the bottom wall of the second mounting groove 204, and the first magnet 300 can be configured to penetrate the bottom wall 106 of the receiving cavity 101, so that the second magnet 400 and the first magnet 300 are in direct contact when aligned.
[0061] In one embodiment, the S pole of the first magnet 300 faces the male buckle 200, and the N pole of the second magnet 400 faces the female buckle 100, so that a magnetic force of mutual attraction is generated between the first magnet 300 and the second magnet 400 in a second direction.
[0062] In another embodiment, the N pole of the first magnet 300 faces the male buckle 200, and the S pole of the second magnet 400 faces the female buckle 100, so that a magnetic force of mutual attraction is generated between the first magnet 300 and the second magnet 400 in a second direction.
[0063] Of course, the magnetic poles of the first magnet 300 and the second magnet 400 are set in such a way that the first magnet 300 and the second magnet 400 attract each other when they are close together, which includes but is not limited to the above-mentioned setting method.
[0064] In one embodiment, one first magnet 300 and one second magnet 400 are provided.
[0065] In another embodiment, a plurality of first magnets 300 are provided and are distributed sequentially in a third direction (i.e., the z-axis direction).
[0066] The number of second magnets 400 is the same as that of first magnets 300, and they are distributed in the third direction. They also correspond one-to-one with the first magnets 300 in the second direction to further enhance the magnetic attraction between the female buckle 100 and the male buckle 200.
[0067] In an exemplary embodiment, the first magnet 300 may be a permanent magnet. The type of the first magnet 300 is not limited to this, and it may be any form in the prior art, as long as it can achieve the above-mentioned functions.
[0068] In an exemplary embodiment, the second magnet 400 may be a permanent magnet. The type of the second magnet 400 is not limited to this, and it may be any form in the prior art, as long as it can achieve the above-mentioned functions.
[0069] In one implementation scheme, such as Figure 2 As shown, the guide surface 104 is a plane.
[0070] In another implementation, the guide surface 104 is a curved surface.
[0071] In one embodiment, the contact surfaces of the first limiting part 105 and the second limiting part 202 are planar or curved surfaces.
[0072] The locking device of this invention can be applied to the handlebars and bags of two-wheeled vehicles. Two-wheeled vehicles include, but are not limited to, bicycles, electric bicycles, and motorcycles. The bag can be used to hold items such as mobile phones. The female buckle 100 can be attached to the handlebar, and the male buckle 200 to the bag. Alternatively, the male buckle 200 can be attached to the handlebar, and the female buckle 100 to the bag.
[0073] Of course, this is just one application scenario, and the locking device of this utility model can also be used in other scenarios.
[0074] The operation of the locking device of the present invention will be described below with reference to the accompanying drawings. Its application scenario is that the female buckle 100 is set on the bag and the male buckle 200 is set on the rod. The user needs to install the bag on the rod.
[0075] When the male buckle 200 and the female buckle 100 are not locked, the insertion part 201 of the male buckle 200 can be roughly aligned with the guide surface 104 of the receiving cavity 101 of the female buckle 100 (see mating instructions). Figure 4 ).
[0076] When the male buckle 200 and the female buckle 100 come close together, the insertion portion 201 of the male buckle 200 contacts the guide surface 104 (see mating details). Figure 5 The insertion part 201 slides relative to the female buckle 100 along the guide surface 104 towards the female buckle 100 (there is relative movement between the female buckle 100 and the male buckle 200; if the female buckle 100 is fixed, the male buckle 200 moves; if the male buckle 200 is fixed, the female buckle 100 moves). Guided by the guide surface 104, the insertion part 201 moves relative to the female buckle 100 along the first direction and also along the second direction until the insertion part 201 is in contact with the bottom wall 106 of the receiving cavity 101 (see mating details). Figure 6 ).
[0077] As the male buckle 200 slides relative to the female buckle 100 along the guide surface 104, the first magnet 300 and the second magnet 400 generate a magnetic force that attracts each other. Under the action of this magnetic force, the insertion part 201 can slide along the guide surface 104 toward the female buckle 100. That is, during the sliding process along the guide surface 104 toward the female buckle 100, the user no longer needs to apply a force toward the male buckle 200 or the female buckle 100.
[0078] like Figure 6As shown, when the insertion part 201 is in contact with the bottom wall 106 of the receiving cavity 101, the second limiting part 202 of the insertion part 201 is aligned with the first slot 108 in the first direction, and the first limiting part 105 of the female buckle 100 is aligned with the second slot 203 of the male buckle 200 in the first direction.
[0079] After the insertion part 201 is attached to the bottom wall 106 of the receiving cavity 101, the second limiting part 202 of the male buckle 200 is inserted into the first slot 108 of the female buckle 100, and the first limiting part 105 of the female buckle 100 is inserted into the second slot 203 of the male buckle 200 (see mating details). Figure 2 At this time, the first limiting part 105 and the second limiting part 202 can limit each other in the second direction, thereby completing the mutual locking of the male buckle 200 and the female buckle 100 in the second direction.
[0080] When the second limiting part 202 of the male buckle 200 is inserted into the first slot 108 of the female buckle 100, the first magnet 300 and the second magnet 400 are aligned in the second direction, and the magnetic force between them reaches its maximum and extends along the second direction.
[0081] The magnetic force can also limit the relative movement of the male buckle 200 and the female buckle 100 in the first direction to prevent the second limiting part 202 of the male buckle 200 from disengaging from the first slot 108 of the female buckle 100 due to shaking, and to prevent the first limiting part 105 of the female buckle 100 from disengaging from the second slot 203 of the male buckle 200.
[0082] exist Figure 2 In one embodiment, the distance of the first slot 108 in the second direction is greater than the thickness of the second limiting part 202 in the second direction, so that the insertion part 201 fits against the bottom wall 106 of the receiving cavity 101, and when the first magnet 300 and the second magnet 400 are aligned in the second direction, the first limiting part 105 and the second limiting part 202 do not contact each other, that is, there is a gap between the first limiting part 105 and the second limiting part 202.
[0083] When the external force along the second direction exceeds the magnetic force between the first magnet 300 and the second magnet 400, the male buckle 200 moves away from the female buckle 100, and the first limiting part 105 and the second limiting part 202 come into contact, thereby restricting the separation of the male buckle 200 and the female buckle 100. That is, although the first magnet 300 and the second magnet 400 have separated at this time, the first limiting part 105 and the second limiting part 202 can still lock the male buckle 200 and the female buckle 100 in the second direction.
[0084] In another embodiment, the distance of the first slot 108 in the second direction can be set to be adapted to the thickness of the second limiting part 202 in the second direction. That is, the distance of the first slot 108 in the second direction is equal to the thickness of the second limiting part 202 in the second direction, so that the insertion part 201 fits against the bottom wall 106 of the receiving cavity 101, and the first limiting part 105 and the second limiting part 202 contact when the first magnet 300 and the second magnet 400 are aligned in the second direction. In this embodiment, a friction part can be provided on the contact surface of the first limiting part 105 and the second limiting part 202 to increase the sliding friction of the first limiting part 105 and the second limiting part 202 in the first direction, preventing them from losing their lock due to shaking. The friction part can be in the form of a corrugated pattern or a component with a high coefficient of friction.
[0085] When it is necessary to separate the male buckle 200 and the female buckle 100, a force is applied to the male buckle 200 from the second side wall 103 of the receiving cavity 101 pointing towards the insertion part 201, or a force is applied to the female buckle 100 from the insertion part 201 pointing towards the second side wall 103, so that the second limiting part 202 of the male buckle 200 disengages from the first slot 108 of the female buckle 100, and the first limiting part 105 of the female buckle 100 disengages from the second slot 203 of the male buckle 200, so that the second limiting part 202 and the first limiting part 105 no longer limit each other in the second direction.
[0086] Then, a force is applied to the male buckle 200 away from the female buckle 100, or a force is applied to the female buckle 100 away from the male buckle 200, thereby separating the male buckle 200 and the female buckle 100.
