Description

Technical Field

[0001] This invention belongs to the field of protective seat technology, specifically a protective seat. Background Technology

[0002] Connectors, also known as plugs or sockets, are generally electrical connectors. They are devices that connect two active components to transmit current or signals. Due to their electrical connection function, connectors are frequently used in new energy vehicles. Typically, during installation, the connector is directly bolted to the vehicle body before power is applied. However, this process has the following drawbacks:

[0003] When the vehicle body is impacted, the connector is more likely to be hit, which may cause the connector and the base to deform, break, or separate under stress, resulting in equipment damage and poor power connection. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a protective seat, which effectively solves the problem that when the vehicle body is impacted, the connector is easily hit, thereby affecting the connection stability of the connector.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective base, comprising a base plate, wherein a buffer base is installed at the bottom end of the base plate;

[0006] The buffer base includes an upper plate below a base plate, a lower plate below the upper plate, a buffer seat between the upper plate and the lower plate, the buffer seat is made of shock-absorbing rubber, the buffer seat has evenly spaced recesses inside, two through slots are symmetrically opened on the upper plate, and a side protection component is installed at the top of the lower plate.

[0007] The side protection assembly includes fixed boxes symmetrically installed on the top of the lower plate. Inside the fixed boxes are movable blocks. A top rod is fixedly installed on the top of the movable block. The top of the top rod passes through a through slot to the inside of a positioning slot. The positioning slots are symmetrically opened at the bottom of the bottom plate. The inner wall of the positioning slots is symmetrically provided with slots.

A connecting exhaust unit is installed between the lower plate and the fixed box. A snap-fit ​​connection unit is installed on the top rod. A magnet control unit is installed on one side of the fixed box.

[0008] Preferably, four fixing screws are installed at the four corners of the bottom of the base plate. Four slots corresponding to the positions of the fixing screws are opened on the upper plate, the lower plate, and the buffer seat. During installation, the fixing screws are inserted into the slots, and the base plate and the buffer base are fixed by nuts. Side slots are symmetrically opened at both ends of the buffer seat, and the fixing box is located inside the side slots. Three wire slots are opened on the upper plate, the lower plate, and the buffer seat (203). The three wire slots are used for the wires of electrical appliances to pass through the base plate.

[0009] Preferably, the connecting exhaust unit includes first air grooves evenly distributed on the lower plate, with each first air groove corresponding to a recess. When the buffer seat is compressed, air inside the recess can enter the first air groove. Two second air grooves are symmetrically distributed inside the lower plate, located below the fixed box. A connecting groove is provided inside the lower plate, connecting each first air groove and the two second air grooves. Side pipes are symmetrically installed on both sides of the fixed box, and air chambers are provided inside the side pipes. The bottom end of the air chamber is connected to the second air groove, and the other end of the air chamber is connected to the inner cavity of the fixed box. An intake and exhaust unit is installed on the air chamber.

[0010] Preferably, the snap-fit ​​connection unit includes an upper inner groove opened inside the top rod, a longitudinal moving block is movably installed inside the upper inner groove, two connecting rods are symmetrically hinged to the top of the longitudinal moving block, and a locking block is hinged to the top of the connecting rod. The locking block is slidably installed inside the rod groove, and the rod groove is symmetrically opened on both sides of the top rod.

[0011] Preferably, the movable block has a lower inner groove inside, which is connected to the bottom end of the upper inner groove. A fixed shaft is symmetrically installed inside the lower inner groove, and a rotating push plate is rotatably installed on the outside of the fixed shaft. A top box is symmetrically installed at the top of the movable block, and a pressure block is movably installed inside the top box. A pressure rod is symmetrically installed at the top of the pressure block. A pressing piston is provided above the movable block. The inner wall of the pressing piston is in close contact with the outer wall of the top rod, and the outer wall of the pressing piston is in close contact with the inner wall of the fixed box. A second spring is installed at an equal angle between the movable block and the pressing piston. The two ends of the fixed shaft are located at the bottom end of the pressure block and the bottom end of the longitudinal moving block, respectively. One end of the air chamber is located above the pressing piston.

[0012] Preferably, the intake and exhaust unit includes a plate groove formed on one side of the air chamber, a guide rod is fixedly installed inside the plate groove, a toothed plate is slidably installed inside the plate groove, a guide plate is installed on the toothed plate, the guide plate is slidably connected to the guide rod, a third spring is fixedly installed on one side of the guide plate, one end of the third spring is fixedly connected to the inner wall of the plate groove, a magnetic block is installed on the guide plate, and an electromagnet is installed on the inner wall of one end of the plate groove.

[0013] Preferably, the air cavity is provided with a rotating plate inside, and a toothed ring is fixedly installed on the outer side of the rotating plate. The toothed ring meshes with the toothed plate. Two first through slots are symmetrically opened on the rotating plate. Through holes are symmetrically opened on the rotating plate. The through holes are composed of small holes. A fixed plate is provided below the rotating plate. The fixed plate is fixedly installed inside the air cavity. The bottom wall of the rotating plate is in close contact with the top wall of the fixed plate, and the rotating plate and the fixed plate are rotatably connected. Second through slots are symmetrically opened on the fixed plate.

[0014] Preferably, two limiting plates are installed on the guide rod. In the original state, when the guide plate is in contact with one of the limiting plates, the first through groove corresponds to the second through groove. When the electromagnet generates a repulsive force on the magnetic block, the guide plate is in contact with the other limiting plate, so that the second through groove corresponds to the through hole.

[0015] Preferably, the magnet control unit includes a transverse air box fixedly installed on one side of the fixed box. The transverse air box and the fixed box are connected in space below the movable block. An exhaust port is opened at the end of the transverse air box. A transverse piston is movably installed inside the transverse air box. The outer wall of the transverse piston is in close contact with the inner wall of the transverse air box. A conductive rod is installed on one side of the transverse piston. Conductive strips are symmetrically installed on the inner walls of both sides of the transverse air box. The two ends of the conductive rod are in contact with the two conductive strips respectively.

[0016] Preferably, a first magnetic plate is installed at the top of the transverse air box, and a second magnetic plate is installed at the bottom of the transverse air box. The two conductive strips are electrically connected to the electromagnet. When the transverse piston moves away from the fixed box, the conductive rod cuts the magnetic field lines to generate current. The current flows into the electromagnet, causing the electromagnet to generate a repulsive force on the magnetic block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) During operation, when the top of the base plate is subjected to an impact force, the buffer seat is compressed to buffer the impact force. The buffer seat is evenly provided with recesses. When the buffer seat deforms, the impact force on the base plate is further released through the recesses, which improves the buffer protection of the equipment at the top of the base plate. At the same time, the base plate moves downward, which compresses the first spring. Under the elastic force of the first spring, the impact force is further buffered, which improves the buffer protection effect of the equipment.

[0019] 2) During operation, the compressed buffer seat causes the air in the recessed part to enter the space above the pressing piston inside the fixed box through the air chamber. This causes the pressing piston to move towards the movable block, pushing the longitudinal block to move upward. The connecting rod pushes the locking block to move outward and lock it into the slot, thereby improving the connection strength between the base plate and the buffer seat, ensuring the installation stability of the equipment base, and protecting the equipment.

[0020] 3) During operation, when the movable block moves downward, the first through slot on the rotating plate aligns with the second through slot on the fixed plate, allowing air to smoothly enter the fixed box. When the movable block moves upward, the rotating plate rotates until the through hole aligns with the second through slot on the fixed plate, causing the airflow to be obstructed by the rotating plate and slowing down. This causes the movable block to continuously consume the force stored in the first spring as it moves upward, thereby damping the first spring and allowing the base plate to move back smoothly, thus protecting the equipment.

[0021] 4) During operation, when the movable block moves downward, the transverse piston moves towards the exhaust port, causing the conductive rod to cut the magnetic field lines to generate current and pass into the electromagnet. This causes the electromagnet to attract the magnetic block, ensuring that the first through slot corresponds to the second through slot, allowing air to smoothly enter the fixed box and ensuring a buffering effect. When the movable block moves back, the conductive rod moves in the opposite direction, causing the electromagnet to repel the magnetic block, thereby driving the rotating plate to rotate to the position where the through hole corresponds to the second through slot, thus facilitating the smooth return of the base plate.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example 1, by Figure 1-12The present invention relates to a protective seat, comprising a base plate 1, a buffer base 2 mounted on the bottom end of the base plate 1, the buffer base 2 comprising an upper plate 201 located below the base plate 1, a lower plate 202 located below the upper plate 201, a buffer seat 203 mounted between the upper plate 201 and the lower plate 202, the buffer seat 203 being made of shock-absorbing rubber, the buffer seat 203 having uniformly distributed recesses 204 inside, two through slots 205 symmetrically formed on the upper plate 201, and a side protective component 3 mounted on the top end of the lower plate 202.

[0039] The side protection assembly 3 includes a fixed box 301 symmetrically installed on the top of the lower plate 202. A movable block 302 is installed inside the fixed box 301. A top rod 303 is fixedly installed on the top of the movable block 302. The top of the top rod 303 passes through a through slot 205 to the interior of a positioning slot 101. The positioning slot 101 is symmetrically opened at the bottom of the base plate 1. A slot 102 is symmetrically opened on the inner wall of the positioning slot 101. A first spring 304 is symmetrically installed at the bottom of the movable block 302. The bottom of the first spring 304 is fixedly connected to the inner bottom wall of the fixed box 301. A connecting exhaust unit 305 is installed between the lower plate 202 and the fixed box 301. A snap-fit ​​connection unit 306 is installed on the top rod 303. A magnet control unit 308 is installed on one side of the fixed box 301. Four fixing screws are installed at the four corners of the bottom of the base plate 1. The upper plate 201, the lower plate 202, and the buffer seat 203 are also equipped with... Four slots are provided corresponding to the positions of the fixing screws. During installation, the fixing screws are inserted into the slots, and the base plate 1 and the buffer base 2 are fixed with nuts. The buffer base 203 has symmetrical side slots at both ends. The fixing box 301 is located inside the side slots. Three wire slots 4 are provided on the upper plate 201, the lower plate 202, and the buffer base 203. The three wire slots 4 are used to pass the wires of the electrical appliances on the base plate 1. When the top of the base plate 1 is subjected to an impact force, the buffer base 203 is compressed to buffer the impact force. The buffer base 203 has evenly distributed recesses 204. When the buffer base 203 deforms, the recesses 204 further release the impact force on the base plate 1, improving the buffer protection of the equipment at the top of the base plate 1. At the same time, the base plate 1 moves downward, causing the first spring 304 to be compressed. Under the elastic force of the first spring 304, the impact force is further buffered, improving the buffer protection effect of the equipment.

[0040] The connecting exhaust unit 305 includes first air grooves 3051 evenly distributed on the lower plate 202, and the first air grooves 3051 correspond one-to-one with the recesses 204. When the buffer seat 203 is compressed, the air inside the recesses 204 can enter the first air grooves 3051. Two second air grooves 3053 are symmetrically distributed inside the lower plate 202. The second air grooves 3053 are located below the fixed box 301. A connecting groove 3052 is provided inside the lower plate 202, which connects each of the first air grooves 3051 and the two second air grooves 3053. Side pipes 3054 are symmetrically installed on both sides of the fixed box 301. An air chamber 3055 is provided inside the side pipe 3054. The bottom end of the air chamber 3055 is connected to the second air groove 3053, and the other end of the air chamber 3055 is connected to the inner cavity of the fixed box 301. An intake and exhaust unit 307 is installed on the air chamber 3055.

[0041] The snap-fit ​​connection unit 306 includes an upper inner groove 3062 formed inside the top rod 303. A longitudinal moving block 3065 is movably mounted inside the upper inner groove 3062. Two connecting rods 3064 are symmetrically hinged to the top of the longitudinal moving block 3065. A locking block 3063 is hinged to the top of each connecting rod 3064. The locking block 3063 is slidably mounted inside the rod groove 3061, which is symmetrically formed on both sides of the top rod 303. The movable block 302 has a lower... The lower inner groove 3066 is connected to the bottom end of the upper inner groove 3062. A fixed shaft 3067 is symmetrically installed inside the lower inner groove 3066. A rotating push plate 3068 is rotatably installed on the outside of the fixed shaft 3067. A top box 3069 is symmetrically installed at the top of the movable block 302. A pressure block 30610 is movably installed inside the top box 3069. A pressure rod 30611 is symmetrically installed at the top of the pressure block 30610. A [missing information - likely a design feature] is located above the movable block 302. A pressure piston 30612 is provided, with its inner wall tightly against the outer wall of the top rod 303 and its outer wall tightly against the inner wall of the fixed box 301. A second spring 30613 is installed at an equal angle between the movable block 302 and the pressure piston 30612. The two ends of the fixed shaft 3067 are located at the bottom ends of the pressure block 30610 and the longitudinal moving block 3065, respectively. One end of the air chamber 3055 is located above the pressure piston 30612, providing a buffer. When seat 203 is compressed, the air in recess 204 enters through air chamber 3055 into the space above the pressure piston 30612 inside the fixed box 301. This causes the pressure piston 30612 to move toward the movable block 302, pushing the longitudinal block 3065 to move upward. Through connecting rod 3064, the locking block 3063 moves outward and locks into the slot 102, thereby improving the connection strength between the base plate 1 and the buffer seat 203, ensuring the stability of the equipment base installation, and protecting the equipment.

[0042] The intake and exhaust unit 307 includes a plate groove 3071 formed on one side of the air chamber 3055. A guide rod 3072 is fixedly installed inside the plate groove 3071. A toothed plate 3073 is slidably installed inside the plate groove 3071. A guide plate 3074 is installed on the toothed plate 3073. The guide plate 3074 is slidably connected to the guide rod 3072. A third spring 3075 is fixedly installed on one side of the guide plate 3074. One end of the third spring 3075 is fixedly connected to the inner wall of the plate groove 3071. A magnet 3076 is installed on the guide plate 3074. A magnet 3076 is installed on the inner wall of one end of the plate groove 3071. The electromagnet 3077 has a rotating plate 3078 inside the air cavity 3055. A gear ring 3079 is fixedly installed on the outer side of the rotating plate 3078, and the gear ring 3079 meshes with the gear plate 3073. Two first through slots 30710 are symmetrically opened on the rotating plate 3078, and through holes 30711 are symmetrically opened on the rotating plate 3078. The through holes 30711 are composed of small holes. A fixing plate 30712 is provided below the rotating plate 3078. The fixing plate 30712 is fixedly installed inside the air cavity 3055, and the bottom wall of the rotating plate 3078 is in close contact with the top wall of the fixing plate 30712. Furthermore, the rotating plate 3078 is rotatably connected to the fixed plate 30712. The fixed plate 30712 has symmetrically opened second through slots 30713. Two limiting plates are installed on the guide rod 3072. In the original state, when the guide plate 3074 is in contact with one of the limiting plates, the first through slot 30710 corresponds to the second through slot 30713. When the electromagnet 3077 generates a repulsive force on the magnetic block 3076, the guide plate 3074 contacts the other limiting plate, so that the second through slot 30713 corresponds to the through hole 30711. When the movable block 302 moves downward, the first through slot on the rotating plate 3078... The second through slot 30710 on the fixed plate 30712 corresponds to the second through slot 30713 on the fixed plate 30712, allowing air to smoothly enter the fixed box 301. When the movable block 302 moves upward, the rotating plate 3078 rotates until the through hole 30711 corresponds to the second through slot 30713 on the fixed plate 30712. This causes the air return flow to be obstructed by the rotating plate 3078, slowing down the flow rate. As the movable block 302 moves upward, it continuously consumes the force stored in the first spring 304, thereby damping the first spring 304 and allowing the base plate 1 to move back smoothly, thus protecting the equipment.

[0043] The magnet control unit 308 includes a transverse air box 3081 fixedly installed on one side of the fixed box 301. The transverse air box 3081 is connected to the space below the movable block 302 of the fixed box 301. An exhaust port 3082 is opened at the end of the transverse air box 3081. A transverse piston 3083 is movably installed inside the transverse air box 3081. The outer wall of the transverse piston 3083 is in close contact with the inner wall of the transverse air box 3081. A conductive rod 3084 is installed on one side of the transverse piston 3083. The inner walls on both sides of the transverse air box 3081 are... Conductive strips 3085 are symmetrically installed. The two ends of a conductive rod 3084 are in contact with the two conductive strips 3085 respectively. A first magnetic plate 3086 is installed at the top of the transverse air box 3081, and a second magnetic plate 3087 is installed at the bottom of the transverse air box 3081. The two conductive strips 3085 are electrically connected to an electromagnet 3077. When the transverse piston 3083 moves away from the fixed box 301, the conductive rod 3084 cuts the magnetic field lines, generating current. This current flows into the electromagnet 3077, causing the electromagnet 3077 to engage with the magnetic block 3085. 76 generates a repulsive force. When the movable block 302 moves downward, the transverse piston 3083 moves towards the exhaust port 3082, causing the conductive rod 3084 to cut the magnetic field lines, generating current and passing it into the electromagnet 3077. This causes the electromagnet 3077 to attract the magnetic block 3076, ensuring that the first through slot 30710 corresponds to the second through slot 30713, allowing air to smoothly enter the fixed box 301 and ensuring a buffering effect. When the movable block 302 moves back, the conductive rod 3084 moves in the opposite direction, causing the electromagnet 3077 to attract the magnetic block 3076. The magnetic block 3076 generates a repulsive force, which drives the rotating plate 3078 to rotate to the position corresponding to the through hole 30711 and the second through slot 30713, thereby facilitating the smooth return of the base plate 1. It is necessary to coat the outer wall of the fixed box 301 and the outer wall of the transverse air box 3081 with a magnetic shielding protective coating. The magnetic shielding protective coating provides magnetic shielding protection for the magnetic plate and the conductive rod 3084 inside the transverse air box 3081, so as to avoid electromagnetic interference from the high-voltage equipment in the car to the magnetic plate and to avoid affecting the current generated by the conductive rod 3084.

[0044] Working principle: During operation, the equipment to be installed is first placed on the top of the base plate 1 for protection. When the top of the base plate 1 is subjected to an impact force, the base plate 1 moves downward under pressure, causing the buffer seat 203 to be compressed for buffering. The buffer seat 203 undergoes new deformation during compression, and the impact force on the base plate 1 is further released through the recessed part 204, thereby improving the buffer protection of the equipment on the top of the base plate 1. When the base plate 1 moves downward, the top of the top rod 303 is inserted into the positioning groove 101, thereby pushing the movable block 302 to move downward, causing the first spring 304 to be compressed. Under the left and right pressure of the first spring 304, the impact force is further buffered, improving the protection effect.

[0045] When the buffer seat 203 is compressed, the air inside the recess 204 enters the second air groove 3053 through the first air groove 3051 and the connecting groove 3052, and enters the space above the pressing piston 30612 inside the fixed box 301 through the air chambers 3055 on both sides of the fixed box 301. This generates downward pressure on the pressing piston 30612, thereby pushing the pressing piston 30612 to move towards the movable block 302, pushing the pressure block 30610 downward, causing one end of the rotating push plate 3068 to move downward. After the rotating push plate 3068 rotates around the fixed shaft 3067, the other end moves upward, pushing the longitudinal block 3065 upward. Then, through the connecting rod 3064, it pushes the two locking blocks 3063 to move outward and lock into the locking groove 102, thereby improving the installation stability of the base plate 1 and the upper plate 201, and thus improving the stability of the equipment.

[0046] When air enters the fixed box 301 through the air chamber 3055, the first through slot 30710 on the rotating plate 3078 corresponds to the second through slot 30713 on the fixed plate 30712, allowing air to smoothly enter the fixed box 301. When the movable block 302 moves downward, it pushes the transverse piston 3083 towards the exhaust port 3082 under air pressure transmission, causing the conductive rod 3084 to cut the magnetic field lines between the first magnetic plate 3086 and the second magnetic plate 3087, generating a current in the conductive rod 3084, which is then transmitted to the electromagnet 3077 through the conductive strip 3085. This causes the electromagnet 3077 to attract the magnetic block 3076, thus ensuring the stability of the correspondence between the first through slot 30710 and the second through slot 30713. When the impact force disappears, the movable block 302 moves back under the elastic force of the first spring 304, thereby ensuring the stability of the air chamber 301. Under pressure transmission, the transverse piston 3083 moves back towards the fixed box 301, causing the conductive rod 3084 to move in the opposite direction. This causes the conductive rod 3084 to generate a reverse current, which flows into the electromagnet 3077. The electromagnet 3077 then generates a repulsive force on the magnetic block 3076, pushing the toothed plate 3073 to move. The toothed plate 3073 meshes with the toothed ring 3079, thereby driving the rotating plate 3078 to rotate. This causes the second through slot 30713 to align with the through hole 30711. When the first spring 304 moves upward, it pushes the air above to flow back into the recess 204. When the air flows back through the through hole 30711, the air flow speed slows down due to the obstruction of the rotating plate 3078. This consumes the energy stored in the first spring 304 when it is compressed, thus providing shock absorption for the first spring 304. This allows the base plate 1 to move back smoothly, thereby protecting the equipment at the top of the base plate 1.
