Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the utility model may be practiced otherwise than as specifically illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The battery box locking device and the vehicle provided by the embodiment of the utility model are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1 to 4, the battery box locking device includes a rotary locking mechanism 10, a base 30, and a detection assembly 20; the rotary locking mechanism 10 is rotatably connected with the base 30, the sensing piece 11 is arranged on the rotary locking mechanism 10, the detection assembly 20 is fixed on the base 30, and the rotary locking mechanism 10 is used for locking the battery box; the rotating locking mechanism 10 is used for driving the sensing element 11 to move and switching the sensing element 11 between a first position and a second position, the detecting assembly 20 comprises a first detecting element 21 and a second detecting element 22, the first detecting element 21 and the second detecting element 22 are distributed at intervals, and the first detecting element 21 and the second detecting element 22 are fixed on the base 30; in the case where the sensing piece 11 is located at the first position, the sensing piece 11 faces the first detecting piece 21, the first detecting piece 21 senses the sensing piece 11, and the rotary locking mechanism 10 locks the battery box; when the sensing member 11 is located at the second position, the sensing member 11 faces the second detecting member 22, the second detecting member 22 senses the sensing member 11, and the rotary lock mechanism 10 releases the lock of the battery box.

In the embodiment of the present utility model, since the rotary locking mechanism 10 is rotatably connected with the base 30, and the sensing element 11 is mounted on the rotary locking mechanism 10, the rotary locking mechanism 10 can drive the sensing element 11 to move by rotating on the base 30, and can switch the sensing element 11 between the first position and the second position. Since the detection unit 20 is fixed to the base 30, and when the rotation lock mechanism 10 rotates on the base 30, the rotation lock mechanism 10 rotates with respect to the detection unit 20. Since the detecting assembly 20 includes the first detecting member 21 and the second detecting member 22, and the first detecting member 21 and the second detecting member 22 are spaced apart from each other, the first detecting member 21 and the second detecting member 22 are both fixed on the base 30; under the condition that the sensing piece 11 is positioned at the first position, the sensing piece 11 is opposite to the first detecting piece 21, the first detecting piece 21 senses the sensing piece 11, and the rotary locking mechanism 10 locks the battery box; under the condition that the sensing piece 11 is located at the second position, the sensing piece 11 is opposite to the second detecting piece 22, the second detecting piece 22 senses the sensing piece 11, and the rotary locking mechanism 10 is unlocked to the battery box, so that the sensing piece 11 can be detected by the detecting assembly 20 in real time, and different detection conditions of the sensing piece 11 by the first detecting piece 21 and the second detecting piece 22 in the detecting assembly 20 correspond to different locking states of the rotary locking mechanism 10, specifically, under the condition that the sensing piece 11 is sensed by the first detecting piece 21, the battery box is locked by the rotary locking mechanism 10, and under the condition that the sensing piece 11 is sensed by the second detecting piece 22, the battery box is unlocked by the rotary locking mechanism 10. In summary, in the battery box locking device of the utility model, the detection assembly 20 can detect the locking state of the rotating locking mechanism 10 on the battery box in real time, and the detection assembly 20 is connected with the rotating locking mechanism 10 only through the base 30, which is equivalent to that the detection assembly 20, the base 30 and the rotating locking mechanism 10 form a whole, in the running process of the automobile, the detection assembly 20 and the rotating locking mechanism 10 can synchronously move, namely, the relative shaking amount of the detection assembly 20 and the rotating locking mechanism 10 is smaller, the probability of false judgment is greatly reduced, the reliability of the detection assembly 20 is improved, and the stability of the battery box is further improved.

In addition, in some embodiments, the detecting assembly 20 may further include a mounting block 23, where the mounting block 23 is fixed to the base 30, and the first detecting member 21 and the second detecting member 22 are fixedly connected to the mounting block 23.

Because the mounting block 23 is fixed on the base 30, the first detecting member 21 and the second detecting member 22 are fixedly connected with the mounting block 23, and thus, the mounting block 23 is fixed on the base 30, the first detecting member 21 and the second detecting member 22 can be fixed on the base 30, and the installation is simpler and more convenient.

In the related art, a bracket is often arranged on a certain part of an automobile, then two proximity switches are installed on the bracket, and a detection surface of the proximity switch needs to be led out by using a bolt and is fixed by a locking nut. The detection assembly 20 of the battery box locking device of the utility model is simpler and more convenient to install than the device.

It should be noted that, the mounting block 23 has two counter bores, the base 30 has two corresponding threaded holes, and the mounting block 23 is fixed on the base 30 by inserting bolts into the counter bores and screwing the bolts into the corresponding threaded holes. Of course, the mounting block 23 may be fixed to the base 30 in other manners, for example: the mounting block 23 is bonded to the base 30 by a potting adhesive. The manner in which the mounting block 23 is secured to the base 30 is not limited in this regard.

In addition, in some embodiments, as shown in fig. 6, the base 30 may further include a first fixing plate 31 and a second fixing plate 32, the first fixing plate 31 and the second fixing plate 32 are spaced apart, a portion of the rotating locking mechanism 10 is located between the first fixing plate 31 and the second fixing plate 32, and the rotating locking mechanism 10 is rotatably connected to the first fixing plate 31 and the second fixing plate 32, and the sensing element 11 is mounted on a portion of the rotating locking mechanism 10 between the first fixing plate 31 and the second fixing plate 32; the mounting block 23 is fixed on the surface of the first fixed plate 31, which is away from the rotary locking mechanism 10, and the first fixed plate 31 is provided with a first through hole and a second through hole, the first detection piece 21 is positioned in the first through hole, and the second detection piece 22 is positioned in the second through hole; in the case that the sensing piece 11 is located at the first position, the sensing piece 11 faces the first through hole, so that the sensing piece 11 faces the first detecting piece 21; in the case where the sensing member 11 is located at the second position, the sensing member 11 faces the second through hole, so that the sensing member 11 faces the second detecting member 22.

Because the mounting block 23 is fixed on the surface of the first fixing plate 31, which is away from the rotary locking mechanism 10, and the first fixing plate 31 is provided with the first through hole and the second through hole, the first detection piece 21 is positioned in the first through hole, and the second detection piece 22 is positioned in the second through hole, on the premise that the mounting block 23 is fixed with the first fixing plate 31, the first detection piece 21 and the second detection piece 22 are also respectively positioned in the first through hole and the second through hole on the first fixing plate 31, so that the relative shaking amount of the detection assembly 20 and the base 30 is reduced, and further, the relative shaking amount of the detection assembly 20 and the rotary locking mechanism 10 is reduced; and the first and second detecting

members

21 and 22 are also respectively located in the first and second through holes on the first fixing plate 31, the installation space of the detecting assembly 20 can be reduced. Because the first fixing plate 31 and the second fixing plate 32 are distributed at intervals, part of the rotary locking mechanism 10 is located between the first fixing plate 31 and the second fixing plate 32, the rotary locking mechanism 10 is respectively in rotary connection with the first fixing plate 31 and the second fixing plate 32, and the sensing piece 11 is arranged on part of the rotary locking mechanism 10 between the first fixing plate 31 and the second fixing plate 32, so that the first sensing piece 21 and the second sensing piece 22 can sense the sensing piece 11 on part of the rotary locking mechanism 10 between the first fixing plate 31 and the second fixing plate 32, specifically, under the condition that the sensing piece 11 is located at the first position, the sensing piece 11 is opposite to the first through hole, namely, the sensing piece 11 is opposite to the first sensing piece 21, and the first sensing piece 21 senses the sensing piece 11 at the moment; in the case that the sensing element 11 is located at the second position, the sensing element 11 faces the second through hole, that is, the sensing element 11 faces the second detecting element 22, and at this time, the second detecting element 22 senses the sensing element 11.

In addition, in some embodiments, the first detecting member 21 includes a first hall sensor, the second detecting member 22 includes a second hall sensor, and the sensing member 11 is a magnetic member; alternatively, the first detecting member 21 includes a first photoelectric sensor, the second detecting member 22 includes a second photoelectric sensor, and the sensing member 11 is a reflective plate.

Since the first detecting member 21 includes the first hall sensor, the second detecting member 22 includes the second hall sensor, and the sensing member 11 is a magnetic member, the first hall sensor can sense the magnetic field of the magnetic member when the magnetic member faces the first hall sensor, that is, the detecting assembly 20 senses that the sensing member 11 is located at the first position at this time; in the case that the magnetic member faces the second hall sensor, the second hall sensor may sense the magnetic field of the magnetic member, that is, the sensing member 11 is sensed to be located at the second position by the sensing assembly 20.

Since the first detecting member 21 includes the first photoelectric sensor, the second detecting member 22 includes the second photoelectric sensor, and the sensing member 11 is a light reflecting plate, in the case that the light reflecting plate faces the first photoelectric sensor, the light emitted by the first photoelectric sensor is reflected by the light reflecting plate and received by the first photoelectric sensor, so that the first photoelectric sensor detects the light reflecting plate, that is, the detecting component 20 senses that the sensing member 11 is located at the first position at this time; under the condition that the reflecting plate is opposite to the second photoelectric sensor, light emitted by the second photoelectric sensor is reflected by the reflecting plate and received by the second photoelectric sensor, so that the second photoelectric sensor detects the reflecting plate, that is, the detection component 20 senses that the sensing piece 11 is located at the second position at the moment.

In the related art, the relative shaking amount of the proximity switch and the rotation locking structure is large, so that the detection range of the sensor in the proximity switch needs to be set to be large, so that the sensor cannot leave the detection range of the sensor due to shaking when facing a certain sensor, but the detection range is too large, so that the sensor accuracy is low, and the sensor and the rotation locking mechanism 10 are easy to shake relatively, so that the sensor which is not facing the sensing member 11 can easily detect the sensing member 11, thereby causing false alarm. In the present utility model, since the relative shaking amounts of the detecting unit 20 and the rotary lock mechanism 10 are small, the internal parameters of the first hall sensor/first photosensor and the second hall sensor/second photosensor are modified, that is, the detection ranges are redesigned and calibrated, for example, before the first detecting member 21 and the second detecting member 22 are mounted: when the center of the magnetic part is 2.5mm away from the center of the first Hall sensor, the first Hall sensor senses the sensing part 11, so that the detection range is reduced, the precision of the detection assembly 20 is improved, and the probability of false alarm of the detection assembly 20 is reduced.

It should be further noted that, when the first detecting element 21 includes a first hall sensor, the second detecting element 22 includes a second hall sensor, and the sensing element 11 is a magnetic element, the distance between the sensing surface of the first hall sensor and the mounting surface of the magnetic element is slightly smaller than the limit sensing distance of the first hall sensor, and the distance between the sensing surface of the second hall sensor and the mounting surface of the magnetic element is slightly smaller than the limit sensing distance of the second hall sensor, so that a certain mounting error is reserved between the first hall element and the sensing element 11 and between the second hall element and the magnetic element, so as to eliminate instability caused by other errors, and improve the reliability of the detecting assembly 20. For example: the distance between the sensing surface of the first Hall element and the mounting surface of the magnetic piece is 10 mm, the limit distance of the first Hall element is 15 mm, and the mounting error of 5mm is reserved.

Additionally, in some embodiments, the detection assembly 20 may further include a first enclosure and a second enclosure; the first packaging shell is provided with a first inner cavity, the first detection piece 21 is positioned in the first inner cavity, the first packaging shell is provided with a first opening, the first opening is communicated with the first inner cavity, the detection end of the first detection piece 21 faces the first opening, and the first packaging shell is adhered to the mounting block 23 through waterproof glue; the second packaging shell is provided with a second inner cavity, the second detection piece 22 is positioned in the second inner cavity, the second packaging shell is provided with a second opening, the second opening is communicated with the second inner cavity, the detection end of the second detection piece 22 faces the second opening, and the second packaging shell is adhered to the mounting block 23 through waterproof glue.

Because the first packaging shell is provided with the first inner cavity, the first detecting piece 21 is positioned in the first inner cavity, the first packaging shell can protect the first detecting piece 21 from the external injury of the first packaging shell, and the damage to the first detecting piece 21 is greatly reduced. Since the first package has the first opening, the first opening is communicated with the first inner cavity, and the detection end of the first detection member 21 faces the first opening, the first detection member 21 can still perform normal induction on the induction member 11 under the condition of being protected by the first package. Because the first encapsulation shell is adhered to the mounting block 23 through the waterproof glue, no water vapor permeates into the first encapsulation shell at the joint of the first encapsulation shell and the mounting block 23, a certain waterproof effect is achieved, and the first detection piece 21 is prevented from being affected by the water vapor to reduce the performance.

Because the second packaging shell is provided with the second inner cavity, the second detecting piece 22 is positioned in the second inner cavity, and therefore the second packaging shell can protect the second detecting piece 22 from the external injury of the second packaging shell, and the damage to the second detecting piece 22 is greatly reduced. Since the second package has the second opening, the second opening is communicated with the second inner cavity, and the detection end of the second detection member 22 faces the second opening, the second detection member 22 can still perform normal induction on the induction member 11 under the condition of being protected by the second package. Because the second encapsulation shell is adhered to the mounting block 23 through the waterproof glue, no water vapor permeates into the second encapsulation shell at the joint of the second encapsulation shell and the mounting block 23, a certain waterproof effect is achieved, and the second detection piece 22 is prevented from being affected by the water vapor to reduce the performance.

The first packaging shell and the second packaging shell are made of aluminum alloy materials, have good corrosion resistance, compression resistance and falling resistance, and can better protect the sensors inside. Of course, other materials may be used for the first package housing and the second package housing, for example: and (3) rubber. The materials of the first package housing and the second package housing are not limited herein.

In addition, in some embodiments, the battery box locking device may further include an alarm, a first signal processor, and a second signal processor, wherein an input end of the first signal processor is electrically connected to the first detecting member 21, and an input end of the second signal processor is electrically connected to the second detecting member 22; the output end of the first signal processor and the output end of the second signal processor are electrically connected with the alarm; the first signal processor is used for processing the signal sent by the first detecting element 21, the second signal processor is used for processing the signal sent by the second detecting element 22, and the alarm sends alarm information to the user when the signal received by the first signal processor or the second signal processor is different from the preset signal.

Since the input end of the first signal processor is electrically connected to the first detecting element 21 and the input end of the second signal processor is electrically connected to the second detecting element 22, the first signal processor can receive the signal sent by the first detecting element 21 and process the signal sent by the first detecting element 21, and the second signal processor can receive the signal sent by the second detecting element 22 and process the signal sent by the second detecting element 22. Because the output end of the first signal processor and the output end of the second signal processor are both electrically connected with the alarm, the alarm sends alarm information to the user under the condition that the signals received by the first signal processor or the second signal processor are different from the preset signals, so that after the first signal processor and the second signal processor process the received signals, whether the sensing piece 11 is at the preset position or not is determined by comparing the received signals with the preset signals, namely, whether the locking state of the rotary locking mechanism 10 to the battery box is the preset state or not is determined, and if the locking state is not the preset state, the first signal processor or the second signal processor can control the alarm to send the alarm information, so that the user can know that the battery box locking device is likely to be faulty at the moment.

It should be noted that, the preset position of the sensing element 11 can be only the first position or the second position, that is, only the first detecting element 21 senses the sensing element 11 or only the second detecting element 22 senses the sensing element 11. However, it may occur that the sensing member 11 is not sensed by the first sensing member 21 and the second sensing member 22 for a long time, and the battery box locking device is in a fault state at this time, and one of the first signal processor and the second signal processor receives a signal different from the preset signal and controls the alarm to send out alarm information.

In addition, in some embodiments, as shown in fig. 5, in the case that the first detecting member 21 includes a first hall sensor, the second detecting member 22 includes a second hall sensor, and the sensing member 11 is a magnetic member, the rotating locking mechanism 10 may further include a non-magnetized member 13 and a mechanism body 12, the mechanism body 12 is rotationally connected with the base 30, the non-magnetized member 13 is located at an end of the mechanism body 12 near the base 30, and the magnetic member is mounted on the non-magnetized member 13.

Since the first detecting member 21 includes the first hall sensor and the second detecting member 22 includes the second hall sensor, in the case where the sensing member 11 is a magnetic member, the magnetic member is mounted on the non-magnetization member 13, so that the magnetic member and the metal member are not in direct contact, and the magnetic member is prevented from magnetizing the metal portion of the rotary lock mechanism 10. Because the mechanism body 12 is rotationally connected with the base 30, the non-magnetized member 13 is located at one end of the mechanism body 12 near the base 30, so that the rotary locking mechanism 10 can still normally rotate relative to the base 30 on the premise that the magnetic member is not in direct contact with the metal part on the rotary locking mechanism 10, and the position of the magnetic member can still be opposite to the first detecting member 21 or the second detecting member 22.

It should be noted that, if the rotary locking mechanism 10 is made of metal material, the magnetic element will magnetize the rotary locking mechanism 10, and the first detecting element 21 and the second detecting element 22 will sense the magnetic element, and also sense the magnetized rotary locking mechanism 10, in the above case, no matter the magnetic element is located at the first position or the second position, the magnetized rotary locking mechanism 10 will sense both the first detecting element 21 and the second detecting element 22, so the magnetized rotary locking mechanism 10 will interfere the sensing of the magnetic element by the detecting element, so that the detecting element cannot detect the position of the magnetic element, and the sensing failure of the detecting element is caused. In the present utility model, therefore, the rotary lock mechanism 10 includes a mechanism body 12 and a non-magnetized member 13, the non-magnetized member 13 being used for mounting a magnetic member, preventing the magnetic member from directly contacting a metal material, and preventing the magnetic member from magnetizing the rotary lock mechanism 10.

It should be further noted that, the non-magnetizing member 13 may be a nylon block, the nylon block is fixed at one end of the mechanism body 12 close to the base, and the magnetic member is fixed on the nylon block, so that the magnetic member is prevented from magnetizing the rotary locking mechanism 10 when the rotary locking mechanism 10 is made of a metal material. Of course, the non-magnetized member 13 may be made of other materials that are not easily magnetized, such as: an aluminum alloy. The material of the non-magnetized member 13 is not limited in this embodiment.

The non-magnetized member 13 is screwed to the mechanism body 12 by a bolt, and screw-fastening glue is used to improve the connection strength.

In addition, in some embodiments, as shown in fig. 8, the detection assembly 20 may further include a first indicator light 24 and a second indicator light 25, where the first indicator light 24 and the second indicator light 25 are mounted on the mounting block 23; the first indicator lamp 24 is electrically connected with the first detecting member 21, and the second indicator lamp 25 is electrically connected with the second detecting member 22; the first indicator lamp 24 is turned on in the case that the first detecting member 21 senses the sensing member 11, and the second indicator lamp 25 is turned on in the case that the second detecting member 22 senses the sensing member 11.

Since the first indicator lamp 24 is electrically connected with the first detecting member 21, and the second indicator lamp 25 is electrically connected with the second detecting member 22, the first indicator lamp 24 can be turned on and off to display the sensing condition of the first detecting member 21 to the sensing member 11, and the second indicator lamp 25 can be turned on and off to display the sensing condition of the second detecting member 22 to the sensing member 11, specifically, the first indicator lamp 24 is turned on and the second indicator lamp 25 is turned off when the first detecting member 21 senses the sensing member 11, and the second indicator lamp 25 is turned on and the first indicator lamp 24 is turned off when the second detecting member 22 senses the sensing member 11. The first indicator lamp 24 and the second indicator lamp 25 are both installed on the installation block 23, so that in the process of disassembling and installing the battery box by a worker, the position of the sensing piece 11 can be better determined by observing the first indicator lamp 24 and the second indicator lamp 25, and the locking state of the rotary locking mechanism 10 to the battery box can be further determined.

The first indicator lamp 24 and the second indicator lamp 25 may be mounted on a side of the mounting block 23 facing away from the first detecting element 21 and the second detecting element 22, or may be mounted on an adjacent surface of the mounting block 23 having the first detecting element 21 and the second detecting element 22, and may be disposed upward. The installation positions of the first indicator lamp 24 and the second indicator lamp 25 are only convenient for the staff to observe, and the embodiment of the utility model is not limited herein.

In addition, in some embodiments, as shown in fig. 7, a side of the mounting block 23 facing away from the first and

second sensing pieces

21 and 22 has a wire outlet hole 231, and the wire outlet hole 231 is used to draw out the cables of the first and

second sensing pieces

21 and 22.

Because the side of the mounting block 23, which is away from the first detecting member 21 and the second detecting member 22, is provided with the wire outlet 231, the cables of the first detecting member 21 and the second detecting member 22 are led out from the wire outlet 231, so that the arrangement of the cables is facilitated, and meanwhile, the materials of the shielding layer and the protecting layer in the cables are saved.

It should be noted that, in the related art, two proximity switches are used to detect the position of the sensing element 11 on the rotating locking mechanism 10, and the cables of the two proximity switches are separated, resulting in a disorder of wiring, and the materials of the shielding layer and the protection layer in the cables are increased.

It should be noted that, the cables of the first detecting member 21 and the second detecting member 22 are connected to the sensor connector 26, so that the sensor connector 26 is connected to the power source, so that the first detecting member 21 and the second detecting member 22 can be simultaneously powered, that is, only one electrical interface is needed for the battery box locking device by the sensor connector 26. And the first detecting piece 21 and the second detecting piece 22 can be electrically connected with other components through the sensor connector 26, and in the maintenance and disassembly process, only the sensor connector 26 is required to be disconnected with other components, and the wires in the cable are not required to be disconnected with other components one by one.

An embodiment of the present utility model provides a vehicle, which includes a battery box and a battery box locking device in any of the above embodiments, where the battery box is connected to the battery box locking device.

In the embodiment of the present utility model, since the rotary locking mechanism 10 is rotatably connected with the base 30, and the sensing element 11 is mounted on the rotary locking mechanism 10, the rotary locking mechanism 10 can drive the sensing element 11 to move by rotating on the base 30, and can switch the sensing element 11 between the first position and the second position. Since the detection unit 20 is fixed to the base 30, and when the rotation lock mechanism 10 rotates on the base 30, the rotation lock mechanism 10 rotates with respect to the detection unit 20. Since the detecting assembly 20 includes the first detecting member 21 and the second detecting member 22, and the first detecting member 21 and the second detecting member 22 are spaced apart from each other, the first detecting member 21 and the second detecting member 22 are both fixed on the base 30; under the condition that the sensing piece 11 is positioned at the first position, the sensing piece 11 is opposite to the first detecting piece 21, the first detecting piece 21 senses the sensing piece 11, and the rotary locking mechanism 10 locks the battery box; under the condition that the sensing piece 11 is located at the second position, the sensing piece 11 is opposite to the second detecting piece 22, the second detecting piece 22 senses the sensing piece 11, and the rotary locking mechanism 10 is unlocked to the battery box, so that the sensing piece 11 can be detected by the detecting assembly 20 in real time, and different detection conditions of the sensing piece 11 by the first detecting piece 21 and the second detecting piece 22 in the detecting assembly 20 correspond to different locking states of the rotary locking mechanism 10, specifically, under the condition that the sensing piece 11 is sensed by the first detecting piece 21, the battery box is locked by the rotary locking mechanism 10, and under the condition that the sensing piece 11 is sensed by the second detecting piece 22, the battery box is unlocked by the rotary locking mechanism 10. In summary, in the battery box locking device of the utility model, the detection assembly 20 can detect the locking state of the rotating locking mechanism 10 on the battery box in real time, and the detection assembly 20 is connected with the rotating locking mechanism 10 only through the base 30, which is equivalent to that the detection assembly 20, the base 30 and the rotating locking mechanism 10 form a whole, in the running process of the automobile, the detection assembly 20 and the rotating locking mechanism 10 can synchronously move, namely, the relative shaking amount of the detection assembly 20 and the rotating locking mechanism 10 is smaller, the reliability of the detection assembly 20 is improved, the occurrence probability of misjudgment is greatly reduced, and the stability of the battery box is further improved.
