DETAILED DESCRIPTION
[0047] Based on the above factors, the technical core of the utility model is to provide a lock structure to prevent external liquids such as water from entering the backpack through the lock core.
[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel work are within the scope of protection of the utility model.
[0049] See also Figure 1-Figure 7 In a first aspect, the utility model discloses a lock structure 100 for a backpack of a vehicle, through which the backpack can be opened and closed.
[0050] The lock structure 100 includes a lock core 101 and a lock core cover 102 , wherein the lock core 101 is sealed and installed on the backpack to prevent liquids such as water from entering the backpack through the connection between the lock core 101 and the backpack.
[0051] The lock core cover 102 covers the end of the lock core 101 away from the backpack to prevent foreign matter from entering the lock core 101 , thereby effectively protecting the lock core 101 .
[0052] The lock core 101 is provided with a liquid discharge mechanism for discharging liquid to the outside of the lock core 101. The liquid discharge mechanism can timely discharge the water or other liquid in the lock core 101, thereby preventing the water or other liquid from entering the backpack and causing the items in the backpack to get damp.
[0053] In some embodiments, the lock structure 100 further includes a lock housing 103, which is sealed and mounted on the backpack. Specifically, a mounting hole for mounting the lock housing 103 is provided on the backpack. Figure 7 As shown, the lock shell 103 is a cylindrical structure with one end open, and the outer wall of the open end of the lock shell 103 is provided with a limiting boss 103a, the lock shell 103 is installed in the installation hole, and the limiting boss 103a is limitedly abutted against the outer wall of the backpack, in order to achieve the sealing between the lock shell 103 and the backpack, the lock shell 103 is provided with a sealing gasket 108, and the sealing gasket 108 is located between the limiting boss 103a and the outer wall of the backpack to seal the lock shell 103 and the backpack. In order to reduce the weight of the lock shell 103, the limiting boss 103a can be set as a truncated cone with a decreasing cross section along the direction away from the backpack.
[0054] In order to prevent the lock structure 100 from protruding from the backpack, in a specific embodiment of the utility model, a receiving groove is provided on the backpack, the mounting hole is opened at the bottom of the receiving groove, and the limiting boss 103a is received in the receiving groove. Specifically, the receiving groove is formed by a part of the outer wall of the backpack being recessed into the inner cavity of the backpack.
[0055] like Figure 6 and Figure 7 As shown, an external thread is provided on the outer wall of the lock housing 103, and the external thread of the lock housing 103 is connected to a nut 107, and the nut 107 cooperates with the limiting boss 103a to clamp the backpack, so that the lock housing 103 is fixed to the backpack. In this embodiment, by screwing the nut 107, backpacks of different thicknesses can be used, thereby improving the versatility of the lock structure 100.
[0056] The lock core 101 is inserted into the lock housing 103 , and the outer wall of the lock core 101 is sealed and connected to the inner wall of the lock housing 103 at a preset position. Specifically, a sealing ring 110 can be provided between the lock core 101 and the lock housing 103 to achieve sealing between the two.
[0057] like Figure 2-Figure 4As shown, the liquid discharge mechanism includes a liquid discharge through hole 104 provided on the lock core 101, and the inlet of the liquid discharge through hole 104 is connected to the inner cavity of the lock core 101, and the outlet of the liquid discharge through hole 104 is located between the preset position of the outer wall and the lock core cover 102. The liquid such as water in the lock core 101 can flow out to the inner wall of the lock shell 103 along the liquid discharge through hole 104, and flow out to the outside along the inner wall of the lock shell 103. Since the outlet of the liquid discharge through hole 104 is located between the preset position of the outer wall and the lock core cover 102, and the lock shell 103 is sealed at the preset position of the outer wall, after the liquid flows out from the liquid discharge through hole 104 to the inner wall of the lock shell 103, it cannot flow into the backpack along the lock shell 103, and can only be discharged to the outside, thereby preventing the items in the backpack from getting damp due to the liquid entering the backpack.
[0058] It should be noted that the number of the drainage through hole 104 is not limited to 1, and may be set to 2 or more. The drainage through hole 104 may be a circular hole or a square hole, etc. In this embodiment, the drainage through hole 104 is a square hole as an example, specifically, the length of the square hole is 4 mm and the width is 3 mm.
[0059] It should also be noted that the drainage mechanism is not limited to the drainage through hole 104 , but may also include a drainage groove provided on the lock core 101 , or a drainage pipe connected to the inner cavity of the lock core 101 .
[0060] It can be understood that, in order to facilitate processing, the drainage through hole 104 can be set as a straight hole. Of course, the drainage through hole 104 can also be set as a curved hole, etc.
[0061] In order to facilitate the discharge of water or other liquids in the lock core 101, a drainage hole 104 can be set at the bottom of the lock core 101, so that water or other liquids in the lock core 101 can quickly enter the drainage hole 104 and be discharged, avoiding the accumulation of water or other liquids in the lock core 101.
[0062] In some embodiments, Figure 2 As shown, the lock core 101 has a keyhole 101a, and the lock core cover 102 has a keyhole 102a, which is arranged opposite to the keyhole 101a, so that the car key can be inserted into the keyhole 101a through the keyhole 102a, and the lock core 101 is turned to open and close the lock.
[0063] The inlet of the liquid discharge hole 104 is located between the lock core cover 102 and the keyhole 101a, and is lower than the keyhole 101a, so as to prevent liquids such as water from entering the backpack along the keyhole 101a.
[0064] In order to reduce the amount of liquid such as water that enters the lock core 101, the lock structure 100 further includes a lock core baffle 105, such as Figure 5As shown, the lock core baffle 105 can be opened and closed and installed at the key hole 102a. Specifically, the lock core baffle 105 can be pressed at the key hole 102a by a torsion spring 109, and the lock core baffle 105 can be opened by pushing the lock core baffle 105. It can be understood that the above-mentioned lock core baffle 105 is pressed at the keyhole 102a by the torsion spring 109 to block the keyhole 102a, which is only a specific embodiment of the present invention. In actual applications, a sliding groove can also be opened at the end of the lock core cover 102 facing the lock core 101, so that the lock core baffle 105 slides along the sliding groove. The compression spring is accommodated in the sliding groove, and one end is fixed on the lock core cover 102, and the other end is connected to the lock core baffle 105 to push the lock core baffle 105 to move to the position of blocking the keyhole 102a. When the keyhole 102a needs to be opened, it is only necessary to push the lock core baffle 105 to squeeze the compression spring to expose the keyhole 102a.
[0065] In some embodiments, Figure 2 and Figure 3 As shown, an annular connecting tube 101b is provided at one end of the lock core 101 connected to the lock core cover 102, and the annular connecting tube 101b is sealingly sleeved in the lock shell 103. Specifically, a sealing boss 101b-1 is provided outside the annular connecting tube 101b, and a sealing groove is opened on the sealing boss 101b-1. A sealing ring 110 is sleeved in the sealing groove, and the sealing ring 110 is sealingly fitted with the inner wall of the lock shell 103, and the sealing ring 110 is used to realize the sealed connection between the lock core 101 and the lock shell 103.
[0066] like Figure 4 As shown, the lock core cover 102 blocks the end of the annular connecting tube 101b away from the lock core 101 to achieve blocking of the lock core 101. The drainage through hole 104 is provided on the annular connecting tube 101b. The setting of the annular connecting tube 101b, on the one hand, facilitates the connection with the lock housing 103 and the lock core cover 102, and on the other hand, increases the space for storing liquids such as water entering the lock core 101, further preventing liquids from entering the backpack.
[0067] In some embodiments, the drainage hole 104 is provided at the bottom of the inner wall of the annular connecting tube 101b. It should be noted that the bottom of the inner wall of the annular connecting tube here refers to the bottom of the lock structure 100 when it is installed on the backpack of the vehicle, so that liquids such as water can be discharged as quickly as possible along the drainage hole 104.
[0068] In some embodiments, a guide groove is provided on the inner wall of the annular connecting tube 101b. Specifically, the guide groove is provided around the inlet of the drainage hole 104, and the cross section of the guide groove gradually decreases along the direction from the top to the bottom of the annular connecting tube 101b. It should be noted that the direction from the top to the bottom of the annular connecting tube 101b is limited to the direction when the lock structure 100 is installed on the backpack of the vehicle for use, which is only for the convenience of expression and does not have other specific meanings. The provision of the guide groove further facilitates the rapid entry of liquids such as water entering the lock core 101 into the drainage hole 104 for discharge, which is convenient and quick.
[0069] Of course, a drainage groove may be provided on the inner wall of the lock housing 103 either alone or simultaneously, one end of the drainage groove being connected to the bottom end of the drainage through hole 104, and the other end of the drainage groove extending to the end of the lock housing 103 away from the backpack. The provision of the drainage groove facilitates the discharge of the liquid in the drainage through hole 104. It should be noted that the bottom of the drainage groove may be provided in a downwardly inclined direction from one end to the other end of the drainage through hole 104, further facilitating the outflow of the liquid.
[0070] It is understandable that an inclined surface may be used instead of the drainage groove, that is, the inner wall of the bottom end of the lock housing 103 is arranged to be inclined downward along the direction from one end to the other end of the drainage through hole 104 .
[0071] In some embodiments, the lock structure 100 further includes a lock tongue 106 , which is mounted on the lock housing 103 and is in driving connection with the lock core 101 , and is used to extend out of the lock housing 103 to lock the backpack, or to retract into the lock housing 103 to unlock the backpack.
[0072] The locking tongue 106 is used to slide on the locking surface 106a of the mounting plate of the backpack, and at least a part of it is concave to reduce the contact area between the locking tongue 106 and the mounting plate, thereby reducing the friction force of the mounting plate on the locking tongue 106, so that when the backpack is hit by an external force and the mounting plate vibrates, it can avoid the friction between the mounting plate and the locking tongue 106, which causes the locking tongue 106 to shrink into the lock shell 103 and be opened by mistake.
[0073] It can be understood that the above-disclosed locking surface 106a of the lock tongue 106 is concave to reduce the contact area between the lock tongue 106 and the mounting plate is only a specific embodiment of the present invention. In actual application, it can also be set that along the direction in which the lock tongue 106 extends out of the lock housing 103, the locking surface 106a is inclined in the direction away from the mounting plate, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.
[0074] The backpack includes a bag body and a bag cover, wherein the lock structure 100 is integrally mounted on the bag cover of the backpack, and the mounting plate is a part of the bag body. The locking tongue 106 is engaged with the mounting plate to lock the bag cover to the bag body.
[0075] In some embodiments, a sliding groove 103 b is provided in the lock housing 103 , and the locking tongue 106 can be slidably installed in the sliding groove 103 b . The sliding groove 103 b limits the sliding direction of the locking tongue 106 to avoid problems such as the locking tongue 106 being tilted.
[0076] The car key is inserted into the keyhole 101a and rotated, driving the lock core 101 to rotate. A driving groove 106b is provided on one side of the lock surface 106a of the lock tongue 106. The end of the lock core 101 extending into the backpack passes through the groove wall of the sliding groove 103b and extends into the driving groove 106b. When the lock core 101 rotates, it acts on the sliding groove 103b, thereby pushing the lock tongue 106 to rotate. Due to the limiting effect of the sliding groove 103b on the lock tongue 106, the lock tongue 106 can only move in the direction of extending out of the lock shell 103 or shrinking into the lock shell 103.
[0077] In order to facilitate the resetting of the lock tongue 106, a specific embodiment of the utility model discloses that a return spring is installed in the sliding groove 103b, one end of the return spring is connected to the sliding groove 103b, and the other end is connected to the lock tongue 106, so that the lock tongue 106 is in a state of extending out of the lock housing 103 under normal conditions.
[0078] A second aspect of the present invention provides a backpack device, comprising a backpack and a lock structure 100 as in any one of the above embodiments, wherein the lock structure 100 is installed on the backpack.
