[0089] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0090] Reference Figure 1 and Figure 2 As shown, for the convenience of introduction, the upper and lower directions are adopted in the corresponding drawings to facilitate the introduction of the relative position relationship between the various parts in this application, which should not be understood as a limitation on the absolute position.

[0091] Moreover, in the present application, the first direction corresponds to the up and down direction. Here, the first direction indicates the up and down direction only for the convenience of introducing the specific embodiments of the present application. There is no absolute corresponding relationship between the first direction and the up and down direction.

[0092] The first directions of the present application are only for expressing relative positional relationships. They only indicate approximate orientations rather than absolute geometric relationships.

[0093] According to the first aspect of the present application, reference Figures 1 to 5 , a collision detection sensor 100 is provided, including: a base 110, a contact member 120 and a converter 130.

[0094] The contact member 120 and the base 110 are movably connected so that the contact member 120 can move relative to the base 110 . The converter 130 is used to convert the change of the relative position of the contact member 120 and the base 110 into the change of the output current of the collision detection sensor 100 .

[0095] Through the above technical solution, the converter 130 is used to convert the relative position change between the contact member 120 and the base body 110 into the change of the output current of the collision detection sensor 100, so that the impact degree of the detected area can be detected according to the value of the output current.

[0096] In the present application, the area to be tested may be the bottom of the power battery, the plug-in port of the power battery, or other areas on the vehicle 1 that need to be tested for impact. In the present application, the impact degree of the power battery is the main test object.

[0097] In some embodiments, reference Figure 1 and Figure 2 The converter 130 includes: a conversion conductor 131 and a feedback component 132 .

[0098] The conversion conductor 131 is used to transmit the output current of the collision detection sensor 100 , and the feedback component 132 is used to change the magnetic field of the conversion conductor 131 and / or the resistance of the conversion conductor 131 in response to the change in the relative position of the contact 120 and the base 110 .

[0099] By setting a conversion conductor 131 and a feedback component 132, the conversion conductor 131 is used to transmit the output current of the collision detection sensor 100, and the feedback component 132 can change the magnetic field in which the conversion conductor 131 is located when the relative position of the contact piece 120 and the base body 110 changes accordingly, thereby changing the output current of the collision detection sensor 100 transmitted by the conversion conductor 131. The impact degree of the power battery can be detected by detecting the value of the output current of the collision detection sensor 100 transmitted by the conversion conductor 131, and the characterization method is easy to detect.

[0100] Of course, in response to the change in the relative position of the contact member 120 and the base body 110 , the feedback component 132 can change the resistance of the conversion conductor 131 , and further can change the output current of the collision detection sensor 100 .

[0101] In some embodiments, reference Figure 3 , the feedback component 132 includes: an induction component 1321.

[0102] The inductive component 1321 is used to generate a magnetic field in which the conversion conductor 131 is located. The conversion conductor 131 is in the magnetic field generated by the inductive component.

[0103] The magnetic field in which the conversion conductor 131 is located is generated by setting the inductive component 1321, and the conversion conductor 131 is set in the magnetic field generated by the inductive component. When the relative position of the contact piece 120 and the seat body 110 changes, the magnetic field generated by the inductive component 1321 will also change, thereby causing the induced current generated by the conversion conductor 131 after the magnetic field changes to also change.

[0104] Therefore, the induced current with different current values ​​can be output according to the degree of change in the relative position of the contact member 120 and the seat body 110, so that the impact degree of the power battery can be detected according to the value of the current output by the collision detection sensor 100, which is simple and easy to operate.

[0105] Of course, in some other embodiments, the feedback component 132 may also include:

[0106] The variable resistor (not shown in the figure) can adjust the resistance value through the variable resistor, thereby also changing the current output by the collision detection sensor 100.

[0107] The feedback component 132 may include an inductive component 1321 or a variable resistor, both of which can be used to change the output current value of the collision sensor. The adjustment methods of the two structures are simple and easy to operate.

[0108] In some embodiments, reference Figure 2 The seat body 110 includes or is connected with: an adjusting component 133.

[0109] The adjusting component 133 is used to change the magnetic field generated by the induction component 1321 , wherein the adjusting component 133 is configured as an electrical conductor.

[0110] By providing the adjustment component 133 , the magnetic field generated by the induction component 1321 can be changed so that the conversion conductor 131 transmits different current values, thereby enabling the collision detection sensor 100 to output different current values.

[0111] In some embodiments, reference Figure 2, the adjustment component 133 is constructed as a sheet structure; during the movement of the contact member 120 relative to the seat body 110, the adjustment component 133 is suitable for cutting the magnetic flux lines of the magnetic field generated by the induction component 1321 to change the output current of the conversion conductor 131 transmitting the collision detection sensor 100.

[0112] By constructing the adjustment component 133 as a sheet structure, the sheet structure of the adjustment component 133 can increase the contact area of ​​the magnetic flux lines of the magnetic field generated by the cutting sensing component 1321 to maximize the change of the output current of the conversion conductor 131 transmitting the collision detection sensor 100.

[0113] In some embodiments, reference Figure 1 , the contact member 120 and the base body 110 form a relative movement along the first direction.

[0114] By making the contact member 120 and the seat body 110 perform relative movement along the first direction, the magnetic flux lines of the magnetic field can be cut along the preset first direction to ensure the stability of the magnetic flux lines cutting, thereby making the collision detection sensor 100 output a stable current value.

[0115] In the present application, the first direction may be an up-and-down movement, that is, the contact member 120 and the seat body 110 form an up-and-down movement along the first direction.

[0116] In some embodiments, along a projection plane perpendicular to the first direction, a projection of the adjusting component 133 and a projection of the sensing component 1321 are completely staggered.

[0117] By completely staggering the projection of the adjusting component 133 and the projection of the sensing component 1321 along a projection plane perpendicular to the first direction, interference between the adjusting component 133 and the sensing component 1321 can be avoided when the relative positions of the contact member 120 and the seat body 110 change, thereby ensuring stable operation of the collision sensor.

[0118] In some embodiments, along a projection plane perpendicular to the first direction, the projection of the conversion conductor 131 is located within the projection of the inductive component 1321 .

[0119] By locating the projection of the conversion conductor 131 within the projection of the induction component 1321 along a projection plane perpendicular to the first direction, the conversion conductor 131 can generate a maximum current due to the change in the magnetic flux of the magnetic field of the induction component 1321, thereby avoiding the situation where the current is too small and cannot be detected.

[0120] In some embodiments, reference Figure 4The inductive component 1321 is used to provide a central space 1321a that runs through the central space 1321a in a plane-parallel direction perpendicular to the first direction; wherein at least a portion of the conversion conductor 131 is located in the central space 1321a.

[0121] By utilizing the sensing component 1321 to provide a central space 1321a that runs through a plane parallel to the first direction, at least a portion of the conversion conductor 131 is located in the central space 1321a, and the sensing component 1321 and the conversion conductor 131 are reasonably arranged, the overall structure of the collision detection sensor 100 can be more compact and can output a stable current.

[0122] Exemplarily, the induction component 1321 can be constructed as an induction coil, the conversion conductor 131 can be constructed as a wire, and the induction coil can be connected to a low-voltage power supply. Therefore, the coil will generate a lower magnetic field. After the adjustment component 133 cuts the magnetic flux lines of the magnetic field, the magnetic field changes, so the induced current generated by the wire will also change, and the generated induced current will be used as the current output by the collision detection sensor 100. When the relative positions of the seat body 110 and the contact piece 120 are different, the magnetic flux lines of the magnetic field of the coil will be cut to different degrees by the adjustment component 133, thereby enabling the collision detection sensor 100 to output different current values ​​when the relative positions of the seat body 110 and the contact piece 120 are different.

[0123] In some embodiments, reference Figure 5 The collision detection sensor 100 further includes: a mounting member 140 .

[0124] The contact member 120 is used to provide a conversion cavity 1322a, and the mounting member 140 is used to connect the inductive component 1321 and the conversion conductor 131 with the contact member 120, wherein at least part of the inductive component 1321 and the conversion conductor 131 are located in the conversion cavity 1322a.

[0125] By setting the mounting member 140, the mounting member 140 is used to connect the induction component 1321 and the conversion conductor 131 to the contact member 120, and at least part of the induction component 1321 and the conversion conductor 131 is located in the conversion cavity 1322a, thereby achieving the effect of installing the induction component 1321 and the conversion conductor 131 in the conversion cavity 1322a of the contact member 120.

[0126] In this application, in some embodiments, reference is made to Figure 4 and Figure 5 The mounting member 140 is used to provide a through space 140a that penetrates along a plane-parallel direction perpendicular to the first direction, wherein the inductive component 1321 is suitable for surrounding at least a portion of the mounting member 140, and the mounting member 140 surrounds at least a portion of the conversion conductor 131.

[0127] By utilizing the mounting member 140 to provide a through space 140a that penetrates along a plane parallel to the first direction, the sensing component 1321 is adapted to surround at least a portion of the mounting member 140, and the mounting member 140 surrounds at least a portion of the conversion conductor 131, thereby completing the sleeve connection of the sensing component 1321, the mounting member 140, and the conversion conductor 131. This structure can further save the volume occupied by the feedback component 132, so as to optimize the structural arrangement of the feedback component 132.

[0128] Exemplarily, the mounting member 140 is also configured as a conductor and is constructed as a copper tube, which enables the conversion conductor 131 to better generate an induced current in the magnetic field generated by the induction component 1321 .

[0129] In some embodiments, reference Figure 2 The seat body 110 is used to provide a accommodating cavity 110a that can accommodate the adjusting component 133, wherein, along the projection plane perpendicular to the first direction, the projection of the outer wall of the accommodating cavity 110a formed by the seat body 110 falls into the projection of the inner wall of the conversion cavity 1322a formed by the contact piece 120, so that when the contact piece 120 moves relative to the seat body 110 along the first direction, the accommodating cavity 110a of the seat body 110 overlaps with the accommodating cavity 110a of the contact piece 120.

[0130] In the present application, a accommodating cavity 110a capable of accommodating an adjusting component 133 is provided by utilizing a seat body 110, and along a projection plane perpendicular to the first direction, a projection of an outer wall of the accommodating cavity 110a formed by the seat body 110 falls within a projection of an inner wall of a conversion cavity 1322a formed by the contact member 120, so that during the movement of the contact member 120 relative to the seat body 110 along the first direction, the accommodating cavity 110a of the seat body 110 overlaps with the accommodating cavity 110a of the contact member 120, that is, the seat body 110 can be transported into the conversion conductor 131 of the contact member 120, so that the adjusting component 133 can cut the magnetic flux lines of the magnetic field generated by the induction component 1321. This method can be coordinated with the magnitude of the impact force received by the seat body 110 so that the degree to which the adjusting component 133 cuts the magnetic flux lines of the magnetic field generated by the induction component 1321 also has a magnitude.

[0131] In some embodiments, reference Figure 2 The collision detection sensor 100 further includes: a reset member 150 .

[0132] The reset member 150 is located between the contact member 120 and the base body 110 , wherein the reset member 150 is adapted to act on the contact member 120 and the base body 110 respectively, so that the contact member 120 and the base body 110 tend to move away from each other.

[0133] By setting the reset member 150, when the relative positions of the contact member 120 and the seat body 110 change so that the collision detection sensor 100 stops outputting current, the reset member 150 can move the contact member 120 and the seat body 110 away from each other, so as to detect the degree of impact on the power battery next time. This method does not require much user participation and is easy to use.

[0134] Exemplarily, the reset member 150 can be constructed as a columnar spring, one end of the columnar spring is connected to the upper wall of the contact member 120, and the other end of the columnar spring is connected to the lower wall of the seat body 110. When the relative position of the seat body 110 and the contact member 120 changes, for example, the seat body 110 and the contact member 120 approach each other, the columnar spring will be compressed, and the elastic potential energy of the compressed columnar spring can make the contact member 120 and the seat body 110 tend to move away from each other.

[0135] It should be noted that both ends of the reset member 150 can be connected to the seat body 110 and the contact member 120 respectively by bolts.

[0136] In some embodiments, reference Figure 3 The collision detection sensor 100 further includes: a guide structure 160 .

[0137] The guide structure 160 guides the relative movement between the contact piece 120 and the base body 110 , wherein the guide structure 160 is located between the inner side wall of the contact piece 120 and the outer side wall of the base body 110 .

[0138] By providing the guide structure 160 to guide the relative movement between the contact member 120 and the base body 110 , the contact member 120 and the base body 110 can be stably moved in the first direction.

[0139] Exemplarily, the guide structure 160 can be constructed as a guide rail and guide groove structure, for example, a guide rail is set on the inner wall surface of the contact piece 120, and a guide groove is opened on the inner wall surface of the seat body 110. The relative movement of the guide rail and the guide groove is more stable, and this setting method is also easy to open the mold.

[0140] In some embodiments, reference Figure 1 The collision detection sensor 100 further includes: a pressure detection component 170 .

[0141] The pressure detection member 170 can be used to enable the collision detection sensor 100 to output a collision limit current, wherein the pressure detection member 170 is located in the conversion cavity 1322 a , and the induction component 1321 is located between the pressure detection member 170 and the adjustment component 133 .

[0142] The pressure detection component 170 can be configured as a pressure plate. After the relative positions of the base 110 and the contact component 120 move to the limit, the pressure detection component 170 will cause the collision detection sensor 100 to output a collision limit current, indicating that the impact degree on the power battery has reached the limit and immediate inspection is required.

[0143] It should be noted that after the pressure detection component 170 detects pressure, it indicates that the body of the contact component 120 is also damaged and inspection is required.

[0144] In the collision detection sensor 100 of the present application, the change speed of the relative positions of the base 110 and the contact component 120 depends on the speed of the foreign object impacting the bottom. The force values generated by the foreign object at different speeds are also different. Therefore, the impact force on the bottom can be judged according to the magnitude of the current.

[0145] Therefore, when the compression speed of the change speed of the relative positions of the base 110 and the contact component 120 is faster, the generated current is larger, and vice versa, the generated current is smaller.

[0146] According to the second aspect of the present application, refer to Figure 6 , a collision detection system 20 is provided, including: a collision detection sensor 100 and a controller 200.

[0147] Among them, the collision detection sensor 100 is the collision detection sensor 100 described above, and the controller 200 is configured to output collision level data according to the change of the output current of the collision detection sensor 100.

[0148] The collision detection system 20 has all the beneficial effects of the above-mentioned collision detection sensor 100, and will not be elaborated herein.

[0149] Moreover, the collision detection system 20 of the present application can correspondingly output collision level data according to the change of the output current of the collision detection sensor 100, and can distinguish the collision levels for the user to better distinguish the impact degree on the power battery.

[0150] In the present application, the collision levels can be divided into no collision, low-level damage, medium-level damage, and high-level damage. The current thresholds corresponding to each level are I0, I1, I2 (i.e., the collision limit current), and the output current of the collision sensor is defined as I output .

[0151] When I0 is greater than I output , the risk level is no collision;

[0152] When I0 < I output < I1, the risk level is low level;

[0153] When I1 < Ioutput When I2, the risk level is medium;

[0154] When I2 < I output the risk level is high.

[0155] The low - level risk warns the user that the battery pack power distribution area has been bumped and warns the user to drive carefully; the medium - level risk warns the user that the rear socket of the battery pack has been bumped and recommends safety and airtightness inspections; the high - level risk warns the user that there is a risk of seal failure at the socket at this time, and to avoid wading, and recommends immediate safety and airtightness inspections of the power battery.

[0156] In some embodiments, the collision detection system further includes: the controller 200 is further configured to obtain the output current of the collision detection sensor 100.

[0157] In this application, by using the controller 200 to obtain the output current of the collision detection sensor 100, the function multiplexing of the controller 200 is realized.

[0158] In some embodiments, the controller 200 includes the vehicle 1 ECU.

[0159] By setting the controller 200 as the vehicle's ECU, it is possible to use the vehicle ECU to multiplex the detection of the impact degree on the power battery, without the need to additionally set up a controller 200, which can reduce costs to a certain extent and simplify the overall structure of the collision detection system.

[0160] According to the third aspect of the present application, a chassis assembly is provided, including a shielding plate and a battery pack having an interface for charging and discharging; the chassis assembly further includes the collision detection sensor 100 as above or the collision detection system as above;

[0161] Wherein, the housing 110 of the collision detection sensor 100 is connected to the shielding plate, and the contact member 120 of the collision detection sensor 100 is used to contact the interface.

[0162] This chassis assembly has all the beneficial effects of the above - mentioned collision detection sensor 100, and the present application will not elaborate here.

[0163] This chassis assembly has all the beneficial effects of the above - mentioned collision detection system, and the present application will not elaborate here.

[0164] In the present application, the base 110 of the collision detection sensor 100 can be connected to the shielding plate, and the contact piece 120 of the collision detection sensor 100 is used to contact the plug interface. After the shielding plate is subjected to the force of foreign matter (such as stones on the road surface), the shielding plate will carry the collision detection sensor 100 upward toward the plug interface. After the contact piece 120 contacts the cantilevered plug interface, it will be limited. At this time, the base 110 will move relative to the contact piece 120, and the adjustment component 133 will cut the magnetic field generated by the induction component 1321 located in the contact piece 120, thereby causing the current induced by the conversion conductor 131 to change.

[0165] In the present application, the collision detection sensor 100 can also act as a buffer. When there is a foreign object bumping into it, the whole formed by the contact piece 120 and the base body 110 can act as an energy absorption box, which absorbs the impact energy through the compression process and the overall stiffness formed by the contact piece 120 and the base body 110, thereby reducing the bump damage to the power battery plug interface.

[0167] Step S102 : outputting collision level data according to the change of the output current of the collision detection sensor 100 .

[0168] By outputting collision level data according to the change of the output current of the collision detection sensor 100 , the impact degree of the power battery plug interface can be detected, so that the user can better distinguish the impact degree of the power battery.

[0169] In some embodiments, the collision detection method further comprises:

[0170] S101 : Obtaining the output current of the collision detection sensor 100 .

[0171] By acquiring the output current of the collision detection sensor 100 , the output current is assigned a level.
