The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Examples

The present application provides a surfboard including a board body 100 and a battery 300 mounted to the board body 100.

As shown in fig. 1, a battery compartment (not shown due to the shielding relationship) is formed in the plate body 100, and a mounting frame 200 is provided at the opening edge of the battery compartment, and the mounting frame 200 may be integrally formed with the plate body 100. The mounting frame 200 may also be detachably mounted to the board body 100, i.e., the mounting frame 200 and the battery 300 constitute a battery pack, which may be installed on a new surfboard and also used for modifying an old surfboard.

When the battery 300 is assembled in the battery compartment of the board 100, the housing 310 of the battery 300 is flush with the mounting frame 200, or flush with the surface of the board 100.

To fix the battery 300, as shown in fig. 2, 3 and 4, a latch hook 210 is formed in the mounting frame 200, and a locking mechanism is formed on the housing 310 of the battery 300, and when the battery 300 is assembled in the battery compartment, the locking mechanism is engaged with the latch hook 210 to prevent the battery 300 from being removed.

Referring to fig. 5 again, the locking mechanism disposed on the housing 310 of the battery 300 includes a handle 400, a holder 500 and a locking pin 610, the holder 500 is fixed to the housing 310, a receiving cavity 510 is formed in the holder 500, the locking pin 610 can protrude from the receiving cavity 510 to cooperate with the locking hook 210 to be locked, and the handle 400 is disposed on an outer surface of the housing 310 and is interlocked with the locking pin 610.

When the battery 300 is disassembled, the handle 400 is pulled in the first direction a from the outside, so that the lock pin 610 can be retracted into the accommodating cavity 510 in the second direction B to be disengaged from the lock hook 210, thereby unlocking and removing the battery 300.

Therefore, when the surfboard of the embodiment needs to replace the battery 300, the handle 400 is pulled to unlock and take out the battery 300, so that the battery 300 is convenient to replace.

In order to mount the battery 300 stably, four holders 500 are provided on the housing 310 of the battery 300, and the four holders 500 are substantially symmetrically arranged at four corners of the housing 310, so that the four corners of the housing 310 have locking pins 610. Correspondingly, four latch hooks 210 are arranged on the mounting frame 200, and the four latch hooks 210 can be independently arranged; the four latch hooks 210 may also be integrally connected, i.e., a continuous flange is formed along the inner wall of the mounting frame 200, and the flange is configured as the latch hook 210.

Referring to fig. 6, the latch hook 210 is seen to have a blocking surface 212, and the blocking surface 212 faces the bottom of the battery compartment of the plate body 100. Accordingly, the lock pin 610 is formed with a lock surface 612, and the lock surface 612 faces the opening of the battery compartment. When the battery 300 is installed in the battery compartment, the locking surface 612 on the locking pin 610 abuts against the blocking surface 212 on the locking hook 210, so as to limit the removal of the battery 300.

Two handles 400 are arranged on the outer surface of the shell 310, and two ends of each handle 400 are linked with one lock pin 610 respectively, so that when the battery 300 needs to be disassembled, two hands respectively hold one handle 400 and pull the handle, that is, the four lock pins 610 can be synchronously separated from the lock hook 210, thereby realizing unlocking. Therefore, the surfboard provided by the embodiment can also take the convenience problem of unlocking and taking out the battery 300 into consideration under the condition that the installation stability of the battery 300 is kept, and the unlocking and taking out of the battery 300 can be completed by one-step operation.

To facilitate mounting of the battery 300, as shown in fig. 6, the latch 610 is further formed with a third inclined surface 611, and the latch hook 210 is formed with a fourth inclined surface 211. The third inclined surface 611 is formed on the rear surface of the locking surface 612, and the fourth inclined surface 211 is formed on the rear surface of the blocking surface 212. When the battery 300 is installed, the battery 300 is aligned with the battery compartment (or aligned with the installation frame 200) and put into and lightly press the housing 310, the lock pin 610 is pressed back to the accommodating cavity 510 under the guiding action of the third inclined surface 611 and the fourth inclined surface 211, when the battery 300 is installed in place, the lock pin 610 slips off from the fourth inclined surface 211 (i.e. the lock pin 610 passes through the hook body part of the lock hook 210), and the lock pin 610 can extend out again, so that the locking surface 612 on the lock pin 610 abuts against the blocking surface 212 on the lock hook 210, and the installation and locking of the battery 300 are completed. Compared with the installation steps of firstly unlocking, then placing the battery 300 and then locking in the prior art, the installation of the battery 300 in the embodiment can be completed only by slightly pressing when the battery 300 is placed, and the installation is convenient and quick.

In the locking mechanism, the linkage structure of the handle 400 and the lock pin 610 can be combined with that shown in fig. 6.

As described above, the holder 500 is fixed to the case 310 of the battery 300, the first slider 600, the second slider 800 and the elastic member 700 are provided in the receiving chamber 510 of the holder 500, and the receiving chamber 510 is provided with the first window 511 and the second window 512.

The lock pin 610 is formed on the first slider 600, and the first slider 600 can move in the first direction a in the accommodating chamber 510 to move the lock pin 610 in the first direction a to extend out of the first window 511 or retract into the first window 511, and engage with the lock hook 210 when the lock pin 610 extends out of the first window 511, and disengage from the lock hook 210 when the lock pin 610 retracts from the first window 511. The elastic member 700 is held between the first slider 600 and the inner wall of the receiving chamber 510 to support the locking pin 610 to extend out of the first window 511 to be locked.

The handle 400 is provided with a connecting rod 810, the connecting rod 810 passes through the second window 512 and is connected with the second slider 800, and the width of the second slider 800 is larger than that of the second window 512, so that the second slider 800 cannot be separated from the second window 512. The second slider 800 is matched with the first slider 600, the second slider 800 can be driven by the handle 400 to move along the second direction B, and when the second slider 800 moves along the second direction B, the first slider 600 can be driven to move along the first direction a.

In some embodiments, the first direction a and the second direction B may be the same direction, the handle 400 is made of a deformable flexible material, when the handle 400 is pulled, two ends of the handle 400 can be drawn together, the connecting rod 810 slides along the first direction a at the second window 512, the second slider 800 is driven to slide along the first direction a, the first slider 600 is driven, and the lock pin 610 retracts into the first window 511 to unlock. In this case, the first slider 600 and the second slider 800 may be provided to be integrally formed.

In this embodiment, the first direction a is perpendicular to the second direction B, and the first slider 600 is provided with a first inclined surface 630, and the second slider 800 is provided with a second inclined surface 820. That is, the first slider 600 and the second slider 800 are respectively formed as wedge blocks, and the first slider 600 is simultaneously coupled with the latch 610 as one body.

In the locking state, as shown in fig. 6 and 7, the locking pin 610 of the first slider 600 protrudes through the first window 511 under the support of the elastic member 700, and the first inclined surface 630 of the first slider 600 abuts on the second inclined surface 820 of the second slider 800.

When unlocking is required, as shown in fig. 8 and 9, the handle 400 is pulled in the second direction B to drive the second slider 800. Since the width of the second slider 800 is greater than the width of the second window 512, the second slider 800 only partially moves out of the second window 512, and it should be noted that, when the second slider 800 is used as a wedge-shaped block, the width of the second slider is the maximum width of the wedge-shaped block, that is, the size of the widest position at the bottom of the wedge-shaped block. During the movement of the second slider 800 in the second direction B, the bottom corner of the second inclined surface 820 abuts against the first inclined surface 630, and as the bottom corner gradually moves upwards, the first slider 600 gradually moves in the first direction a and compresses the elastic member 700 under the guiding action of the first inclined surface 630, and the lock pin 610 retracts into the accommodating cavity 510 to disengage from the lock hook 210.

In order to make the first slider 600 and the second slider 800 fit more stably, the first slider 600 is provided in a structure having a recess 620.

Fig. 10 is a schematic view of the first slider 600 cut away therefrom, which shows the internal structure of the first slider 600, and it can be seen that the first slider 600 has a rectangular body, a locking pin 610 is formed on one surface of the rectangular body, an opening is formed on the other surface of the rectangular body, a recess 620 is formed by recessing inward from the opening, and a first inclined surface 630 is formed on a side wall of the recess 620.

Fig. 11 is a schematic view of the second slider 800 cut away therefrom, which shows the internal structure of the second slider 800, and it can be seen that the second slider 800 is a wedge, the second inclined surface 820 is a wedge surface, and a connection hole for installing the connection rod 810 of the handle 400 is further formed on the second slider 800. The connecting rod 810 can be coupled to the connecting hole in various ways, such as threaded connection, snap connection, etc.

The first slider 600 is disposed in the receiving cavity 510, and the second slider 800 is disposed in the recess 620 of the first slider 600, the opening of the recess 620 corresponding to the second window 512.

The opening size of the recess 620 is not limited by the second window 512. In this embodiment, the opening of the recess 620 is adapted to the width of the second slider 800, and one sidewall of the recess 620 forms a first slope 630 such that the width of the recess 620 gradually increases from the opening to the bottom. Thus, the recess 620 is a wedge-shaped cavity having a width greater than that of the wedge-shaped second slider 800, so that the second slider 800 can partially move out of the recess 620 in the second direction B and push the first slider 600 to move in the first direction a relative to the second slider 800.

When the second slider 800 moves in the second direction B, since the second slider 800 cannot be disengaged from the second window 512, the second slider 800 cannot be disengaged from the recess 620, so that the first slider 600 and the second slider 800 can always maintain the engaged state.

In addition, the cradle 500 is formed with a buffer chamber 520, and the buffer chamber 520 is located between the housing 310 and the receiving chamber 510. Referring again to fig. 6, the holder 500 is attached to the inner surface of the housing 310 to form an inner installation space in which a partition is formed to divide the installation space into a buffer chamber 520 adjacent to the housing 310 and an accommodation chamber 510 distant from the housing 310.

The second window 512 of the accommodating chamber 510 is formed on the partition, and the accommodating chamber 510 is communicated with the buffer chamber 520 through the second window 512. Therefore, when the second slider 800 protrudes from the second window 512, please refer to fig. 9 again, the protruding portion of the second slider 800 is located in the buffer chamber 520.

In the case of providing the buffer chamber 520, the second window 512 does not need to be opened in the housing 310, or the housing 310 does not need to be opened with an excessively large hole so that the second slider 800 can be partially protruded. The housing 310 only needs to be provided with a hole with an inner diameter matched with the diameter of the connecting rod 810.

In the locked state, the second slider 800 is in the accommodation chamber 510, the connection rod 810 is received in the buffer chamber 520, and the handle 400 is close to the surface of the housing 310.

In the unlocked state, the handle 400 is pulled up, the connecting rod 810 extends out of the buffer chamber 520, and the second slider 800 extends partially into the buffer chamber 520.

In both the locked state and the unlocked state, the second slider 800 is not exposed outside the housing 310, and the mechanical performance of the locking mechanism can be effectively protected. Moreover, the sealing performance of the case 310 is improved, the inside of the locking mechanism is easily damaged by water, and water can be prevented from entering the battery 300.

To further improve the sealing performance, an elastic sealing ring or a sliding seal is disposed at the opening of the housing 310 to prevent water from entering through the gap between the inner wall of the opening and the connecting rod 810.

To reduce the external resistance of the surfboard, the connecting rod 810 is configured to be able to be substantially retracted into the cushion chamber 520 such that the handle 400 is affixed to the surface of the housing 310 in the locked state. Alternatively, the overall length of the connecting rod 810 and the second slider 800 is set to be equal to the total height of the buffer chamber 520 and the receiving chamber 510, and in this embodiment, the height of the buffer chamber 520 and the receiving chamber 510 is the size of the buffer chamber 520 and the receiving chamber 510 along the first direction a.

Further, as shown in fig. 12, a groove 311 is formed on the surface of the housing 310 of the battery 300, and the groove 311 is adapted to the shape of the handle 400 and falls into the groove 311 when the handle 400 is attached to the surface of the housing 310. Therefore, the handle 400 can not protrude out of the surface of the plate body 100, the effect of protecting the handle 400 is achieved, the probability that the handle 400 is damaged or the battery 300 falls off due to the fact that the handle 400 rubs and hangs objects is reduced, sundries in water can be effectively prevented from being hung on the handle 400, and the resistance generated by water blocking of the handle 400 is greatly reduced.

The recess 311 is partially expanded outward from the edge position thereof to form an expanded opening 312 away from the handle 400, facilitating the pulling up of the handle 400 from the position of the expanded opening 312. Through the above arrangement, the installation stability and the convenience of disassembly and assembly of the battery 300 are further considered under the condition of reducing the resistance of the surfboard.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
