The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1, a cartesian coordinate system is established, and it is defined that the length direction of the snow rescue device is parallel to the direction shown by the x-axis, the width direction of the snow rescue device is parallel to the direction shown by the y-axis, and the height direction of the snow rescue device is parallel to the direction shown by the z-axis. It is to be understood that the above definitions are merely to facilitate understanding of the relative positional relationship of the parts in the snow rescue apparatus and should not be construed as limiting the present application.

In outdoor activities such as snowboarding or skiing, dangerous situations such as avalanche, stepping on empty and collapse are occasionally encountered. When the user is buried in snow, if the user cannot be rescued in time, life safety can be brought to the user.

The embodiment provides a snow rescue device, which can identify the position of a user to an external landmark when the user is buried in snow, namely identify the position of the user above the snow surface, so that rescuers can find the user in time and the user can be rescued in time.

As shown in fig. 1 to 5, the snow rescue apparatus includes an apparatus case 10, a telescoping mechanism 20, and an identification mechanism 30.

Wherein, telescopic machanism 20 includes a plurality of elastic telescopic unit 21, and a plurality of elastic telescopic unit 21 are the end-to-end connection in proper order. In one embodiment, the elastic expansion unit 21 may comprise a contracted state 21a and an expanded state 21b, and the elastic expansion unit 21 may be switched between the contracted state 21a and the expanded state 21 b. When the elastic expansion unit 21 is in the contracted state 21a, elastic potential energy may be stored in the elastic expansion unit 21, and the elastic potential energy may be used to drive the elastic expansion unit 21 to switch from the contracted state 21a to the extended state 21 b. It will be appreciated that the length of the elastically telescopic unit 21 in the extended state 21b is greater than the length of the elastically telescopic unit 21 in the contracted state 21 a.

The retracting mechanism 20 is telescopically mounted in the device case 10, and the identification mechanism 30 may be mounted at one end of the retracting mechanism 20.

It will be appreciated that the snow rescue apparatus may include a use condition and a non-use condition. When the snow rescue apparatus is not in use, each of the elastic expansion units 21 may be in a contracted state 21a to shorten the length of the expansion mechanism 20, and the expansion mechanism 20 may be contracted in the apparatus case 10. At the same time, the identification means 30 can also be retracted in the device housing 10.

When the snow rescue apparatus is in use, at least one elastic expansion unit 21 of the expansion mechanism 20 may be in an expanded state 21b to increase the length of the expansion mechanism 20. Accordingly, the telescoping mechanism 20 can bring the identification mechanism 30 out relative to the device housing 10.

When the user is buried under snow, the length of the telescopic mechanism 20 can be extended to drive the identification mechanism 30 to extend above the snow surface, so that the rescue workers can know the position of the user. In addition, when the user is buried under the snow, the user basically has no activity space, and the elastic potential energy stored by the elastic telescopic unit 21 per se in the application can drive the elastic telescopic unit 21 to be switched from the contraction state 21a to the extension state 21b so as to drive the identification mechanism 30 to extend out above the snow surface, so that the trouble of manual operation can be reduced, the activity of the user can be reduced, correspondingly, the danger of further collapse of the snow pile and the like caused by the activity of the user can be avoided, meanwhile, the energy consumption of the user can be reduced, and the physical strength of the user can be saved.

As shown in fig. 1 to 4, in some embodiments, the axis L of the telescopic mechanism 20 may extend in the height direction of the snow rescue apparatus. A through hole is formed in a side wall of the device case 10 opposite to the identification mechanism 30, so that the identification mechanism 30 and the telescoping mechanism 20 can extend out of the device case 10. In some embodiments, the side of the device case 10 in which the through-hole is opened may be the top of the device case 10, i.e., the top of the snow rescue device. Correspondingly, a side wall of the device case 10 opposite to the through hole may be a bottom of the device case 10, i.e., a bottom of the snow rescue device.

In some embodiments, the snow rescue apparatus further comprises a cover plate 11 for closing the through hole. When the snow rescue device is not in use, the cover plate 11 can cover the through hole. It will be appreciated that the cover plate 11 is removably connected to the device housing 10 to open the through-hole. Illustratively, the cover plate 11 may be fixed in the through-hole position by a frictional force between the side wall of the cover plate 11 and the inner wall of the through-hole.

When the snow rescue device is used, the cover plate 11 can be separated from the device shell 10 under the pushing of the identification mechanism 30, so that the through hole is opened, and the identification mechanism 30 and the telescopic mechanism 20 can conveniently extend out of the device shell 10. In the process, the cover plate 11 does not need to be manually opened by a user, so that the manual operation steps of the user can be reduced, and the use by the user is facilitated. It can be understood that the friction between the cover plate 11 and the inner wall of the through hole is smaller than the pushing force generated when the telescoping mechanism 20 is triggered, so that the cover plate 11 can be smoothly separated from the through hole.

Of course, in other embodiments, the cover plate 11 may be disposed at the through hole position by screwing, snapping, or the like, so that the user can open the through hole.

As shown in fig. 4 and 5, the telescoping mechanism 20 further includes a base 22. The base 22 can be fixedly connected to an elastic expansion unit 21 of the expansion mechanism 20 farthest from the identification mechanism 30, and the base 22 is connected to an end of the elastic expansion unit 21 away from the identification mechanism 30.

As shown in fig. 3, in some embodiments, the base 22 can be fixedly attached to the bottom of the device housing 10. for example, the base 22 can be fixed to the bottom of the device housing 10 by screwing, snapping, bonding, etc. Meanwhile, one end of the base 22 away from the elastic expansion unit 21 is exposed outside the device case 10.

As shown in fig. 6, a plurality of support legs 221 are further disposed on a side of the base 22 away from the elastic expansion unit 21, and in use, the support legs 221 can be inserted into snow to provide a supporting and fixing function. In one embodiment, the leg 221 is hinged to the base 22 by a hinge (not shown). When the supporting legs 221 are folded, the supporting legs 221 can be embedded in the base 22, and correspondingly, the base 22 can be provided with embedding grooves 222 for accommodating the supporting legs 221. In embodiments, the legs 221 may be provided in three, four, five, etc. numbers.

As shown in fig. 4 and 5, the elastic expansion unit 21 may include a connection seat 211 and an elastic member 212. The connecting seat 211 can be used to connect two adjacent elastic expansion units 21. Specifically, one end of the connecting seat 211 may be connected to one end of the elastic member 212, and the other end of the connecting seat 211 may be connected to the elastic member 212 of the adjacent elastic expansion unit 21, wherein the adjacent elastic expansion unit 21 may refer to the elastic expansion unit 21 near one end of the connecting seat 211. In the elastic expansion unit 21 disposed close to the base 22, one end of the connection seat 211 far from the elastic member 212 may be fixedly connected to the base 22.

Referring to fig. 7 and 8, in some embodiments, the elastic member 212 may be a spiral spring. The elastic member 212 may include a first end 212a and a second end 212b, and when the elastic expansion unit 21 is in the contracted state 21a, a portion between the first end 212a and the second end 212b may be spirally nested in the first end 212a, presenting a spiral structure nested in multiple layers. In some embodiments, the elastic member 212 may be made of a steel plate, and accordingly, when the elastically telescopic unit 21 is in the contracted state 21a, the elastic member 212 may store corresponding elastic potential energy.

When the elastic expansion unit 21 is in the expanded state 21b, the second end 212b can be ejected relative to the first end 212a, and the elastic member 212 is in a spiral tubular structure with a certain length. It will be appreciated that the length of the elastic member 212 in the extended state 21b is greater than the length in the contracted state 21 a.

In some embodiments, the first end 212a of the elastic member 212 may be fixedly connected to the connection seat 211 of the same unit, and the second end 212b may be fixedly connected to the connection seat 211 of the adjacent elastic expansion unit 21.

As shown in fig. 8, in some embodiments, the first end 212a may be fixedly connected to the first connection tube 214 by welding, clamping, or the like, an external thread is disposed on an outer side of the first connection tube 214, an internal thread matched with the first connection tube 214 is disposed on the connection seat 211, and the first connection tube 214 and the connection seat 211 may be detachably connected by screwing.

Correspondingly, the second end 212b may be fixedly connected to the second connection pipe 215 by welding, clamping, or the like, and the second connection pipe 215 may also be connected to the connection seat 211 in the adjacent elastic expansion unit 21 by screwing. In some embodiments, the second connecting tube 215 may extend outward to have a certain thickness, or the corresponding end of the corresponding connecting seat 211 may have a certain inward closing so that the second connecting tube 215 and the corresponding connecting seat 211 are smoothly connected in a matching manner.

In other embodiments, the first connection tube 214 and the second connection tube 215 may be connected to the corresponding connection seat 211 by welding, clamping, or the like.

In an embodiment, when the second end 212b is sprung open relative to the first end 212a, the adjacent elastic expansion units 21 may be pushed to move upward synchronously.

As shown in fig. 9 and 10, in some embodiments, the elastic extension unit 21 further comprises a locking assembly 213 for locking the elastic extension unit 21 in the contracted state 21 a.

Specifically, the locking assembly 213 can include a locking bar 2131 and a connecting wire 2132, one end of the connecting wire 2132 can be fixedly connected to the second end 212 b. The other end of the connecting wire 2132 is fixedly connected to the locking rod 2131. When the elastic expansion unit 21 is in the contracted state 21a, the connecting wire 2132 can be inserted into the elastic element 212, the locking rod 2131 can be limited at one end of the elastic element 212 close to the connecting seat 211, and the locking rod 2131 is connected with the connecting seat 211. Meanwhile, the connecting wire 2132 may pull the second end 212b toward the first end 212a, so that the elastic member 212 stores elastic potential energy, and the elastic member 212 is in a compressed state. During this time, the connecting lines 2132 are under tension. Accordingly, the elastic expansion and contraction unit 21 can be held in the contracted state 21a by the restraining action of the lock lever 2131 and the connection wire 2132.

As shown in fig. 9 and 10, the locking rod 2131 is detachably connected to the connecting seat 211. When the elastic telescopic unit 21 is in the contracted state 21a, the locking rod 2131 is inserted into and connected with the connecting seat 211 to realize locking action. Correspondingly, a pair of locking holes 2111 matched with the locking rod 2131 is formed in the connecting seat 211, the two locking holes 2111 are coaxially arranged, and a connecting line between the two locking holes 2111 is perpendicular to the axis L. It will be appreciated that the two locking holes 2111 are positioned to avoid threads in the attachment socket 211.

When the elastic telescopic unit 21 is in the contracted state 21a, the two ends of the locking rod 2131 can be correspondingly limited and inserted into the two locking holes 2111, and under the action of the locking holes 2111, the locking rod 2131 can be limited in the direction of the axis L.

When the elastic telescopic unit 21 is switched from the contracted state 21a to the expanded state 21b, one end of the locking rod 2131 can be pushed from one side of the connecting seat 211 to be disengaged from the locking hole 2111, so as to enter the connecting seat 211. The locking rod 2131 is inclined by the elastic force of the elastic member 212 and gradually moves away from the first end 212 a. The other end of the locking rod 2131 can also slide into the connecting seat 211 gradually, so that the locking rod 2131 is unlocked from the connecting seat 211 to completely release the second end 212b of the elastic element 212. Subsequently, the elastic member 212 can release the elastic potential energy, so that the second end 212b springs away from the first end 212a, and the elastic expansion unit 21 is switched to the extended state 21 b.

In one embodiment, the locking rod 2131 may have a hemispherical shape at both ends. Meanwhile, when the locking rod 2131 is inserted into the connecting seat 211, two end portions of the locking rod 2131 may be respectively inserted into the locking holes 2111 of the corresponding sides, or protrude for a smaller length relative to the locking holes 2111, for example, the locking rod 2131 may protrude for 0.5mm, 1.0mm, and the like relative to the locking holes 2111. Therefore, the locking rod 2131 can be ensured to slide into the connecting seat 211 smoothly in the unlocking process.

As shown in fig. 1 and 2, in some embodiments, the device housing 10 is further provided with a plurality of trigger keys 72 corresponding to the locking rods 2131 of the telescoping mechanism 20. In the embodiment, the plurality of trigger keys 72 may be arranged in series in the height direction of the snow rescue apparatus. In use, a user can press one of the trigger keys 72 to unlock the corresponding locking rod 2131 from the corresponding connecting seat 211, and release the second end 212b of the corresponding elastic member 212, so that the elastic member 212 springs open.

As shown in fig. 11, a push rod 721 is provided to protrude from the trigger key 72 on a side close to the telescopic mechanism 20. The opposing push rods 721 may be coaxial with the locking rod 2131 when the elastically telescopic unit 21 is in the contracted state 21 a. And the diameter of the push rod 721 may be smaller than the diameter of the locking hole 2111. When the user presses the trigger key 72, the push rod 721 can be pushed to move, and then the push rod 721 pushes the opposite locking rod 2131 to unlock the connecting seat 211.

As shown in fig. 1, 12 and 13, in some embodiments, the snow rescue apparatus further includes a safety catch assembly 73 to prevent a user from operating the telescopic mechanism 20 by mistake when not in use.

Specifically, the safety catch assembly 73 may include an actuation key 731 and a stop plate 732 connected together. Wherein the execution key 731 is slidably installed on the top of the device case 10, and a sliding direction of the execution key 731 is parallel to a length direction of the snow rescue device. The stopper 732 may be located within the device housing 10 and may move synchronously with the actuation key 731. In an embodiment, the stop plate 732 may be located between the push rod 721 and the telescoping mechanism 20.

In the embodiment, the stopper plate 732 has a plurality of through holes 733, and the through holes 733 are disposed in one-to-one correspondence with the push rods 721. In a non-use state, the through holes 733 are staggered with the corresponding push rods 721 along the length direction of the snow rescue device, and one ends of the push rods 721 far away from the trigger keys 72 can be opposite to non-through hole areas in the stop plates 732, so that the push rods 721 are prevented from touching the corresponding locking rods 2131.

When the snow rescue apparatus is used, the actuating key 731 can be pushed to move to drive the stop plate 732 to move relative to the trigger key 72, so that the through hole 733 is opposite to the corresponding push rod 721, that is, the through hole 733 is coaxial with the push rod 721 and the locking rod 2131. In this state, the trigger key 72 can be pressed to push the push rod 721 to pass through the through hole 733, so that the push rod 721 can push the corresponding locking rod 2131 to unlock the connecting seat 211. It will be appreciated that the diameter of the via 733 is greater than the diameter of the pushrod 721.

As shown in fig. 5, 7 and 8, when the elastic expansion and contraction unit 21 is in the expanded state 21b, the interior of the elastic member 212 may be hollow and form a flow passage 2121 for air to flow. In an embodiment, the connecting seat 211 may also be a tubular structure with two open ends, and the flow passage 2121 may communicate with the connecting seats 211 at two ends. Accordingly, the elastic expansion units 21 can communicate with each other, and air flows in the expansion mechanism 20.
